Legal and Ethical Considerations in Marketing, Product Safety, and Essay - 1
Legal and Ethical Considerations in Marketing, Product Safety, and Intellectual Property - Essay Example Correspondingly, recommendations have also been provided in the essay so as to mitigate the identified challenges. Ethical issues relating to marketing and advertising, intellectual property, and regulation of product safety Use of negative advertisement techniques The use of negative techniques refers to the adoption of comparative advertisement strategy by the companies. In this unethical practice, the advertisement focuses on the disadvantages of the competitor’s product. Arguably, in the modern phenomenon, this technique has become a major tool for promoting the utility of the products of a particular company (Majtan & Dubcova, n.d.). Misleading or dishonest advertisement It is one of the most serious ethical problems that have been observed as commonly used by many of the advertisers in the modern day. It involves not only misleading facts about the product but also false impression forecasted. Any advertiser who fails to promote the truth of the product not only goes aga inst morality but also against the law as it violates customer protection rights to information. The advertisement must also not include any kind of false statement regarding the product or claim for the dishonest value of that product (Majtan & Dubcova, n.d.). Copyright infringement It is one of the most serious unethical issues that are observed in the field of intellectual property. Notably, the copyright infringement occurs whenever a person who does not own the copyright violates any of the rights of others without permission. The most common practice found in this aspect is breach of reproduction right and invention of new work base under the existing one (Tehranian, 2007). Use of unsafe raw materials in the production Many of the companies use cheap quality material in the production of its final product for the sake of earning maximum profits. They do not keep consumer health or stakeholders’ interest into consideration being highly concerned about the profitability o f their company. For example, in a free market, if a health drink manufacturing company uses cheap quality ingredients in production, it would ultimately affect the health of the consumers offering the company with profits, but only for a limited period in the short-run, inhibiting the company’s sustainability interests to a substantial extent (Dufferin-Peel Catholic District School Board, 2013). Argue for Direct-to-Consumer (DTC) marketing by drug companies The sponsorship of pharmaceutical drugs through Direct-to-Consumer (DTC) has much significance in the current market scenario as it promotes customer confidence and provides better opportunity to the company to align the marketing strategies with customer preferences to a greater extent. In the US, majority of the drug companies have been found spending double than the total amount in DTC marketing technique (Mogull, 2008). On the contrary, there exist many customers who are strictly against this technique of advertising on grounds that because the technique requires substantial financial investments, the drug companies focusing on direct-to-customers selling concept have to spent maximum money on advertising rather than on research and development. However, considering its positive effects, the Food and Drug Administration (FDA)

Chemistry and Computers Essay But often the device simply acts as the electronic equivalent of an on-off switch. When on, it completes a circuit and lets current flow; when off, it breaks the electrical path. †¢ lone transistors suck- strength in numbers †¢ Transistors are possible because the semiconductors they’re built fromâ€â€elements like silicon and germaniumâ€â€have one strange and very useful property: They carry electricity better than insulators, such as glass, but not as well as conductorsâ€â€aluminum for example. Scientists can push a semiconductor’s conductivity one way or the other by dopingâ€â€adding small amounts of impurities. (Arsenic and boron are two of the commonly used elements. ) â€Å"When you dope silicon you make it act differently,†says Shahidi. â€Å"It can act like an insulator or as a metal. †Doping specific areas of a semiconductor in different ways is what creates a transistor enables its switching action. †¢ Experts have been working for many years to understand how to work with electronic material produced on an increasingly small scale. In the emerging field of nano-science and nano-technologies it is important for scientists to be able to control the structure and bonding of molecules that are used in creating small scale electronic components for products such as computers. Scientists have succeeded in imaging and forming a unique bond between a single gold atom and a single organic molecule called a pentacene. They managed to bind the atom to the pentacene and take images of rearrangements of the electrons participating in the formation of the chemical bond.

edgar allen poe :: essays research papers fc
Poe's first collection, Tales of the Grotesque and Arabesque, appeared in 1840. It contained one of his most famous work, 'The Fall of the House of Usher.' In the story the narrator visits the crumbling mansion of his friend, Roderick Usher, and tries to dispel Roderick's gloom. Although his twin sister, Madeline, has been placed in the family vault dead, Roderick is convinced she lives. Madeline arises in trance, and carries her brother to death. The house itself splits asunder and sinks into the tarn. The tale has inspired several film adaptations. Roger Corman's version from 1960, starring Mark Damon, Harry Ellerbe, Myrna Fahey, and Vincent Price, was the first of the director's Poe movies. The Raven (1963) collected old stars of the horror genre, Vincent Price, Peter, Lorre, Boris Karloff, who mostly played for laughs. According to the director, Price and Lorre "drove Boris a little crazy" - the actor was not used to improvised dialogue. Corman filmed the picture in fi fteen days, using revamped portions of his previous Poe sets. In Poe's Narrative of Arthur Gordon Pym (1838) the secret theme is the terror of whiteness. In the novel Poe has invented tribes that live near the Antarctic Circle. The strange bestial human are black, even down to their teeth. They have been exposed to the terrible visitations of men and white storms. These are mixed together, and they slaughter the crew of Pym's vessel. The Argentinean writer Jorge Luis Borges has assumed that Poe chose the color intuitively, or for the same reasons as in Melville explained in the chapter 'The Whiteness of the Whale' in his Moby-Dick. Later the 'lost world' idea was developed by Edgar Rice Burroughs in The Land That Time Forgot (1924) and other works. During the early 1840s Poe's best-selling work was curiously The Conchologist's First Book (1839). It was based on Thomas Wyatt's work which sold poorly because of its high prize. Wyatt was Poe's friend and asked him to abridge the book and put his own name on its title Page - the publisher had strongly opposed any idea of producing a cheaper edition. The Conchologist's First Book was a success. Its first edition was sold out in two months and other editions followed.

Police Personality Essay
The issue regarding the phrase â€Å"police personality†has acquired great debate. Arguably this has been primarily over the problem of definition and development. What is a police personality? How does it form? Is it a pre-existing condition, thus predisposing certain individuals to police work, or whether it is just a product of occupational socialization (on the job experiences). Perhaps the issue is not as simply dichotomous as that; conceivably it is an amalgam of both predispositions and experiences that shapes this intangible personality. Does this personality make them any different from the general population which they vowed to â€Å"serve and protect†? How do these attitudes and affect not only himself and the department he belongs to but also the police-community relation in general? These are some questions relating to the issue of police personality that will be answered along the way. To start with, how do we define â€Å"police personality†? There are a few who made several models or theories about this idea. According to G.A. Kelly (1955), personality is our abstraction of the activity of a person and our ensuing simplification of this abstraction to all matters of his relationship to other persons, known and unknown, as well as to anything else that may seem particularly valuable. His theory is based on the vantage point of personality as a personal construct model. G. Alport (1937), another theorist describes this as a three-pronged task for a certain individual: (1) self-objectification, (2) extension of self, (3) unifying philosophies of life. According to him, it can be further understood as a mixture of major and minor â€Å"traits†by which a single life is known and that a personality â€Å"trait†is a biological, psychological and social mixture that disposes a person toward specific kinds of action under specific circumstances. (Monte, 1999). With respect to the development of the police personality, Allport can be said to be adhering to the predisposition model-that a certain type of person becomes a police officer as opposed to the notion that job experiences shape the personality construct. A third psychologist, H. Kohut (1977) describes that normal development was a process of interaction between the growing infant and his mirroring and idealizing self-objects. This assumption tends to support the view that police personality is a mixture of the predisposition model and the experience model. But regardless of the process by which this certain personality has developed from, what are these traits that make up a police personality?            The characteristics usually associated with police personalities in present times are machismo, bravery, authoritarianism, cynicism and aggression. Additional characteristics have been associated with police personalities as well: suspicious, solidaristic, conservative, alienated and thoroughly bigoted (Balch, Skolnick 1977). In movies like â€Å"Lethal Weapon†which stars Mel Gibson, we see an image of a cop that is not only brave and proficientâ€â€but a super cop, who can handle almost anything that goes in his way. The movie â€Å"Training Day†by acclaimed actor Denzel Washington also depicts a vicious, sadistic cop. Gone are the days when people picture cops as men in uniform, walking around the neighborhood helping children to get their pet cat down from a tree (a Boy Scout persona). Modern pop culture and the media have greatly helped the public’s perception of today’s policemen.            Little is known about how these men undergo series of screenings in order to be accepted though. Before being hired, aspiring policemen go through several personality tests that determine whether they are capable enough to handle the job. Only men who display particular personality profiles (e.g. bravery, honesty, punctuality) are accepted to the force. But these screening, even with the help of psychologists, does not give us a clear picture of what police personality is all about. In contrast, it tells us what the police persona is NOT. There certain traits that make entry-level policemen unfit for the job. Examples are tardiness, excessive absences, alcoholism, and lack of assertiveness among many others.            From the successful ones however we can gather some commonalities in their traits that may help us define police personality. People who enter the force turn out to be psychologically healthy and competent young men who display common personality features. They are generally assertive and restless, with a high degree of physical energy. One trait that stands out from this however, is cynicism. Some professionals view cynicism as counterproductive and in due course, harmful not only to the individual but to the department as well. It said to that for the most part, it is a precursor to corruption, brutality, and misconduct for men in uniform. However, some also believe that, in recent years, findings show that cynicism is to be considered a police survival tool (Caplan, 2003).            The police personality based on Skolnick’s (1977) idea of the â€Å"working personality†is composed of three main elements: danger, authority, and efficiency. The dangerous nature of being a police officer not only draws officers closer together but also makes them alienated from the general population. The sense of authority by police officers, experienced by interacting with the public, further makes them feel isolated. So is the notion of efficiency in which the use deception as a means of getting the job done. Some experts believe though, that the idea of alienation is not intrinsic to police officers, it rather lies in the community’s perceptions of the policemen. It is important that the community and the force work hand in hand in trying to rid the locale of criminality. In countries that are just developing, criminal cases are usually very high. Thus, the police force must be able to transform their image as a widely feared and despised organization to a friendly and service-driven institution that works in close partnership with the community. This is especially hard when the image of a certain department for example is a corrupt and brutal one. People tend to generalize that idea, and view the force being corrupt and all as a whole.            Examining the psychological and sociological paradigms on police personality we get a clearer view of what makes the police men different from the rest of the population. The psychological paradigm posits that people with certain personalities are drawn to join the force (predisposition model). On the other hand, the sociological model suggests that these traits are developed along the way (based from the day to day experiences of police officers). Police personality, as a distinct entity, does exist. It exists as a result of the convergence of a specific baseline set of desirable personalities and work-related socialization. It is also a utility of, and is strongly characterized by, a police culture, shaped by the needs of officers to uphold personal safety and augment their professional potentials.

Emma and Clueless
Transformations often involve familiar themes but reflect those themes in a different context in order to resonate the values and interests of that society. Thus, context dictates form and meaning as well as the values inherent in the texts. Amy Heckerling’s, 20th century American film, Clueless is a transformation of Jane Austen’s conservative Regency England, Emma. The use of different techniques and medium allow Emma’s themes of personal growth, social structure and the role of women in society to be conveyed in a more appropriate form in Clueless.The main characters, Emma and Cher are representational products of their society and parallels can be drawn in the opening scenes, particularly in relation to self-knowledge. The Bildungsroman progression from delusion to social awareness is a universal value in both texts despite their differing contexts. Emma is introduced as â€Å"handsome, clever, and rich†who had â€Å"a disposition to think a little t oo well of herself. †Austen’s satirical tone as the omniscient narrator alerts the responder to Emma’s inability to understand her position in society. Furthermore, while Emma successfully matches Mr. Weston and Ms.Taylor, her motives are superficial as she sees it as â€Å"the greatest amusement in the world! †She also believes Harriet’s beauty â€Å"should not be wasted on the inferior society†, and it would be â€Å"interesting and highly becoming†to â€Å"improve her†. Austen employs verbal irony through Emma’s dialogue, which exposes her flaws of arrogance and shallowness. However, Emma eventually develops self awareness as shown when she realizes her mistake of matching Harriet with Mr. Elton and influencing her to refuse a suitable marriage with Mr. Martin. There is a similar character development in Cher despite the difference in context.Heckerling implements voice overs to create an immediate sense of irony wh en Cher’s â€Å"way normal life for a teenage girl†is juxtaposed with a dolly-tracking shot of her choosing outfits from a computer operated wardrobe in a grand bedroom. In doing so, Heckerling continues Austen’s satirical mode by highlighting Cher’s lack of social awareness. This is further reinforced through her dialogue, â€Å"I have direction†¦towards the mall†and Dionne’s statement, â€Å"Cher’s main thrill in life is a make-over†¦it gives her a sense of control in a world full of chaos†, which imply her superficial obsession with image and materialistic values.Cher’s final ability to see beyond the superficial and realize her mistakes â€Å"I was just totally clueless†is parallel to Emma’s reconciliation to society and its values. Similar to Austen, Heckerling reflects values that are consistent with any age and time- the absolute necessity for young people to gain social awareness. Socia l hierarchy in Regency England was permanent and immobile. It was governed by strict rules of adherence to rank and place, and was determined by birthright and inheritance. Miss.Churchill and Captain Weston’s marriage challenged the social hierarchy due to a large social imbalance in their marriage, and through authorial intrusion, it was deemed â€Å"an unsuitable connection and did not produce much happiness. †Austen demonstrates the virtually impermeable social structure through her criticism of the Coles and that †it was not for them to arrange the terms on which the superior families would visit them†, indicating that money gained through trade and not birthright, doesn’t indicate status.Emma’s high modality and contemptuous tone employed when she claims â€Å"the yeomanry are precisely the order of people with whom I feel I can have nothing to do†further highlights the inflexibility on class interactions. Finally, Harrietâ€℠¢s marriage to Mr. Martin, a farmer, results in the loss of friendship between Emma and Harriet as stated by Austen’s authorial intrusion, â€Å"the intimacy between her and Emma must sink. †This epitomizes the clear demarcation of status and that Emma shouldn’t associate with Harriet due to their differing social status. Cher’s world also has a class structure that underpins her society.This idea is explored through the camera panning out to take long shots of the rigid societal tiers, whilst Cher introduces Tai to the stratified social groups at school including the â€Å"Persia mafia†, the crew and the â€Å"loadies†. Elton’s indignant tone conveys class consciousness in his rhetorical questions towards Cher as she suggests Tai as a romantic partner, â€Å"Why Tai?! Do you know who my father is? †Later, Cher is abandoned in a carpark by Elton, and the far shot of a blinking neon sign of a clown symbolizes society’s mockery of her attempt to undermine a defined system of class.Clearly, class consciousness pervades both societies, especially in selecting romantic partners. Regency England dictated the position of women in society by strict codes of conduct. Primarily, women of Emma’s class were constrained by society’s expectations of a match within their social class. Captain Weston’s marriage to Miss. Churchill is juxtaposed to Miss. Taylor’s, thus allowing Austen to comment on the female and male positions in society, in that women are meant to be passive and have less say in their marriage. According to Mr.Weston’s idea, â€Å"it’s being a great deal better to chuse than to be chosen, to excite gratitude than to feel it†, hence demonstrating the double moral standard prevalent in society. Furthermore, Emma’s sister, Isabella, is married to John Weston, and through authorial intrusion, Austen comments that â€Å"Isabella always thinks a s he does†demonstrating a women’s duty as a wife. The use of dialogue in Mr. Knightley’s warning to Emma, â€Å"Men of family would not be very fond of connecting themselves with a girl of such obscurity†¦[Harriet]†, exemplifies society’s expectation of women to interact within their own social class.On the other hand, Clueless doesn’t offer the restricted patriarchal world of Austen as young women could be independent, outspoken and have many more choices, including marriage. The focus of the medium shot on Cher as she struts down the schoolyard in her vibrant yellow costuming portrays her outgoing attitude. The eye contact of male passerbys creates vectors and the comment â€Å"As if! †highlight Cher’s disgust at their attention, exemplifying women’s freedom to choose their romantic partners. This idea is reinforced by Cher’s comment on Dionne’s relationship, â€Å"Dee, you could do so much better. Contrary to Austen, Heckerling recognizes the change in the position of women in society in that they have more freedom in their social behavior and relationships. In conclusion, Emma and Clueless offer profound and satirical insights into their respective contexts. While the need for social stability and the need for young people to gain social awareness, remain unchanged, but the position of women in society has shifted dramatically. Such ideas are reinforced by the different mediums, both of which effectively reflect the themes and values of that context.

The History of LCD Technology
The History of LCD Technology An LCD or liquid crystal display is a type of flat panel display commonly used in digital devices, for example, digital clocks, appliance displays, and portable computers. How an LCD Works Liquid crystals are liquid chemicals whose molecules can be aligned precisely when subjected to electrical fields, much in the way metal shavings line up in the field of a magnet. When properly aligned, the liquid crystals allow light to pass through. A simple monochrome LCD display has two sheets of polarizing material with a liquid crystal solution sandwiched between them. Electricity is applied to the solution and causes the crystals to align in patterns. Each crystal, therefore, is either opaque or transparent, forming the numbers or text that we can read. History of Liquid Crystal Displays In 1888, liquid crystals were first discovered in cholesterol extracted from carrots by Austrian botanist and chemist, Friedrich Reinitzer. In 1962, RCA researcher Richard Williams generated stripe patterns in a thin layer of liquid crystal material by the application of a voltage. This effect is based on an electrohydrodynamic instability forming what is now called â€Å"Williams domains†inside the liquid crystal. According to the IEEE, Between 1964 and 1968, at the RCA David Sarnoff Research Center in Princeton, New Jersey, a team of engineers and scientists led by George Heilmeier with Louis Zanoni and Lucian Barton, devised a method for electronic control of light reflected from liquid crystals and demonstrated the first liquid crystal display. Their work launched a global industry that now produces millions of LCDs. Heilmeiers liquid crystal displays used what he called DSM or dynamic scattering method, wherein an electrical charge is applied which rearranges the molecules so that they scatter light. The DSM design worked poorly and proved to be too power hungry and was replaced by an improved version, which used the twisted nematic field effect of liquid crystals invented by James Fergason in 1969. James Fergason Inventor James Fergason holds some of the fundamental patents in liquid crystal displays filed in the early 1970s, including key US patent number 3,731,986 for Display Devices Utilizing Liquid Crystal Light Modulation In 1972, the International Liquid Crystal Company (ILIXCO) owned by James Fergason produced the first modern LCD watch based on James Fergasons patent.

The 10 Deadliest Tsunamis of All Time
The 10 Deadliest Tsunamis of All Time When the ocean floor moves enough, the surface finds out about it - in the resulting tsunami. A tsunami is a series of ocean waves generated by large movements or disturbances on the oceans floor. The causes of these disturbances include volcanic eruptions, landslides, and underwater explosions, but earthquakes are the most common. Tsunamis can occur close to the shore or travel thousands of miles if the disturbance occurs in the deep ocean. Wherever they occur, though, they often have devastating consequences for the areas they hit. For example, on March 11, 2011, Japan was struck by a magnitude 9.0 earthquake that was centered in the ocean 80 miles (130 km) east of the city of Sendai. The earthquake was so large that it triggered a massive tsunami that devastated Sendai and the surrounding area. The earthquake also caused smaller tsunamis to travel across much of the Pacific Ocean and cause damage in places like Hawaii and the west coast of the United States. Thousands were killed as a result of both the earthquake and tsunami and many more were displaced. Fortunately, it was not the worlds deadliest. With a death toll of only 18,000 to 20,000 and Japan being particularly active for tsunamis throughout history, the most recent doesnt even make the top 10 deadliest. Fortunately, warning systems are becoming better and more widespread, which can cut down on the loss of life. Also, more people understand the phenomena and heed the warnings to move to higher ground when a tsunami possibility exists. The 2004 Sumatran disaster spurred UNESCO to set a goal to establish a warning system for the Indian Ocean ​like exists in the Pacific and increase those defenses worldwide. ​​ The Worlds 10 Deadliest Tsunamis Indian Ocean (Sumatra, Indonesia)Estimated Number of Deaths: 300,000Year: 2004 Ancient Greece (Islands of Crete and Santorini)Estimated Number of Deaths: 100,000Year: 1645 B.C.

Some sources may list the tsunami figures along with the earthquake or volcanic eruption death figures and not split out the amount killed just by the tsunami. Also, some numbers may be preliminary and are revised down when missing people are found or revised up when people die of diseases in coming days brought on by the floodwaters.

Research Paper Example The moko symbolized several things. It created tribal identity for in individual and showed genealogy. Moreover, the art form showed an individual’s rank and status in society, with those having the mark considered to have a higher social status than those that did not. The moko marked the stage an individual was at in their life. It marked the transition of an individual from childhood to adulthood. In addition, some forms of the mark showed when an individual became eligible for marriage. The moko was a sacred abject highly valued by the Maori people. In recent times, the people in the rest of the world take interest in the moko with some opting to get the mark. However, the use of moko by the non-Maori in many ways alter the meaning and true function of the mark. One thing that stands out about the Maori culture from the moko is that status ranked importantly in society. Individuals interacted based on their status. Those who ranked lowly in the community worked hard to acq uire some form of status. All through, the moko showed an individual’s status depending on the pattern that came with the mark. Several tattoos were unique to the women that were set aside as a result of their high rank in society. A partial facial moko signified a woman of such high rank in society that never married or got children as finding a mate to match her lineage status became impossible. (Simmons 87) Among men, tattoos on the right side of the face were a symbol of paternal lineage and rank; and showed whether this rank was hereditary or acquired. The left side face had markings showing the lineage and status an individual acquired from their side of the mother. Bravery gave an individual status in society. Warriors that performed exemplary well in war got a moko to show to everyone that met them of their bravery. (Durie 305) Such marks earned them respect and admiration from the society, and in turn added to their social status. The social structure of the Maori ga ve the first born sons a higher social status than that of lower born sons. These first born sons were the only one eligible to become leaders and chiefs. A special moko symbolized this status. However, lower born sons got a chance to achieve status by showing acts of bravery and kindness. Therefore, many used warfare as a chance to buy social status and get a tattoo showing they had rank. Leaders in Maori culture used Moko to symbolize their status. The type of moko showed the rank of a chief. The tattoo on a high ranking chief in the society was so unique that people who saw it immediately linked the individual with the mark with chiefdom and immediately accorded them the respect that came with that mark. Maori chiefs included their moko marks as signs on legal documents such as letters and title deeds. Any document bearing such a mark gained political recognition as validated by the chief; therefore asserting it eligibility. The Maori culture shows through the moko that it was hi ghly stratified along gender lines. The moko on men and women had significant differences. In addition, the marks on men bore different meanings than those done on women. Many times, the moko on women revolved around their eligibility to marry, whom to marry and what status they had in society. On the other hand, the moko among men predominantly showed rank, superiority and bravery. Only men had mokos symbolizing political leadership such as the marks of chiefs. However, marks on women
How software engineering differs from other fields of engineering Essay
How software engineering differs from other fields of engineering - Essay Example The concept is applied with reference to engineering and computer science principles and practices, when exploring the development, operability and the maintenance of software systems. This paper will explore the aspects that differentiate software from other fields of engineering like mechanical and electrical engineering. The paper will also discuss the specific characteristics of the ‘software’ product, which differentiate the field from other engineering domains. The differences between software engineering and other traditional engineering disciplines The field of software engineering, unlike other traditional fields of engineering, can be traced to the growth in the field of computing and information technology. The growth in the field of computing and information technology has prompted the tremendous growth of the field of software engineering (Ghezzi, Jazayeri and Mandrioli, 2003). On the other hand, other fields of engineering can be traced to the development a nd the growth of respective fields of study and practice, and not necessarily the field of computing and information technology (Sommerville, 2008). ... erent from traditional engineering disciplines, in that many of the other fields of engineering – including civil, chemical, mechanical, and electrical engineering – can be traced to the discrete application of mathematical basements. On the other hand, software engineering can be traced to the application of technical computer and mathematical science principles, which resulted from the need of maintaining and improving software systems (Ghezzi, Jazayeri and Mandrioli, 2003). This difference shows that the field depends, mainly, on the principles of discrete mathematics, particularly that related to logic (Jones, 1995). Software engineering is different from traditional engineering fields, in that many of the engineers practicing these other fields construct real artifacts, but software engineers construct virtual/ abstract artifacts. This points out that the products developed by software engineers may not be subjected to the evaluation and the testing which is releva nt to those produced by the engineering practicing in the traditional fields. Additionally, traditional engineering fields are mature fields incorporating continuous mathematics and physical sciences, but software engineering is more immature, and reliant on discrete mathematics and computer sciences (Herbsleb and Goldenson, 1996). In traditional engineering, there are two major concerns about the products produced, including the costs of production and the reliability of the product, which is a function of time and failure (Jalote, 2005). On the other hand, in software engineering, the main concerns related to the products developed include the costs of development and the reliability of the virtual product, which is a function of the number of errors noted for every thousand lines of the source

Developing an Integrated SLA Theory Research Paper
Developing an Integrated SLA Theory - Research Paper Example on this theory, Second language acquisition is mainly concerned the process of acquiring a new language other than the inborn language and how the process is affected by other disciplines such as the social-cultural theories. The theory offers a clear reflection from a new perception, on some of the challenges that people face during new language acquisition. It offers some pedagogical suggestions for foreign linguistic teaching. However according to Moore and Kearsly (1996), foreign language educators ought to maintain three types of interactions: learner- content, learner-tutor and learner-learner. According to Krashen’s theory on second language acquisition, comprehensible input and interactions are crucial. Interactions facilitate practice that has the advantage of enhancing the acquisition and fluency of the foreign language. This paper makes attempts to expound Social-Cultural Theory’s paradigms, its influence on second language acquisition and the tutorial sugges tions for foreign language coaching (Vygotsky, 1978). An overview of main second language acquisition theories that reveal that advance of the concepts of comprehensible input, understandable output, and interactions are significant in the second language acquisition. Many theories contain diverse views on the ways of ensuring interactions and the role it plays in the second language acquisition. Krashen’s theory (1985, 1994) has since becoming the most predominant theory in the acquisition of a second language and teaching exercise. According to the theory, SLA is determined by the extent of the compressible input during teaching. It asserts that the one-way contribution in the second language that is not only understandable but also at the level is just beyond the existing language proficiency of learners. The theory asserts that the prediction upon which learners acquire the notions of the second language relays of the method they get and understand the messages. Krashen’s (1994) offers

Rationalism and Empiricism - Essay Example Empiricism after Hume’s philosophy, however, requires an a posteriori knowledge apart from analytical endeavor for such theory posits that matters of fact in the world may only be ascertained by perceiving through the senses. In the light of an empirical attempt for one to obtain certainty with truths that may be contingent, Hume necessitates engagement with observations wherein an observer becomes capable of designating philosophical connections with contiguity and identity of objects [2]. _____________________ 1. â€Å"Rationalism – Rene Descartes.†2012.

Web. http://www.philosophos.com/philosophical_connections/profile_068.html. A rationalist like Descartes proposes that the knowledge we may acquire is derived from the ideas that are intrinsic by nature. As such, the mathematical knowledge that th e sum of all three angles in any triangle is always equal to 180 degrees is an innate conception that is part of a universal set of absolute truths the discovery of which is made by reasoning. It is believed under the argument of Descartes that since genuine knowledge is inborn, God has created the natural laws for this knowledge to constitute our mental faculties inherently. The rationalist thereby goes on to state – â€Å"there is no single one we cannot understand if our mind proceeds to consider it†for the things conceived already exist as they are and are brought to cognition only to reveal their proofs yet to be unfolded in the absence of regard for senses [3]. On the contrary, nevertheless, an empiricist like Hume maintains that beliefs regarding matters of fact, hence, determine genuine progress for explicating that no self-evident relation exists when ideas bear apparent distinctions and separability within their number. For Hume, we possess no knowledge of s uch factual matters since connections in beliefs presupposed by cause and effect can only be yielded at after experiencing cases with similar characteristics that not even inferential validity of previous encounters would do alone to make adequate explications of these same beliefs [4]. What –ism seems to be stronger in your mind and why? What are the arguments for and against Rationalism and Empiricism?

POLITICAL ECONOMY OF THE SINGLE EUROPEAN MARKET Essay
POLITICAL ECONOMY OF THE SINGLE EUROPEAN MARKET - Essay Example 195 billion budget was prepared by the European Union for the purpose of Structural Funds from the period of January 01, 2000 to December 21, 2006. This allocation of the budget was used in different sectors, especially the transport sector, and poorer regions of the continent were supported and integrated with different developing schemes of these structural funds. On the other hand, the budget for the Cohesion Fund was allocated to the amount of 18 billion, which was also used for different schemes and allocations in the European Union. (Halkier, 2004) In this regard, the major amount of the European Union's funding is spent on the Structural Funds, and the bulk of European Union's funding is made up these structural and cohesion funds. In addition, the Common Agricultural Policy is also included in the bulk of European Union's funding along with the abovementioned funds. (Artis, 2006) The areas and regions of the European continent, which are under the pressure of various difficulties are helped and supported by the European Union's Structural Funds. The decline of the local European industry could be the reason of these difficulties. Else, reduction of farm incomes due to the reduction in commodity prices could also be responsible for the lacking of resources to these regions. (Evans, 1999) In the result, sponsor projects are helped and supported by these structural funds, by which, locally identified needs would be addressed directly by it. Some of the sponsor projects that are fun by the structural funds are credited to train local people with different skills, which may help them in building their careers, or help them in setting-up their new businesses. Mainly, there are two objectives of the European Union's Structural Funds. Firstly, the regions with lack of development are enhanced and advanced by the adjustment of structural funds, which help in promoting development in these areas. Mostly, the lagging-behind areas are supported in the first objective of the European Union's Structural Funds. Secondly, local areas that are found to be facing structural difficulties are converted socially and economically by the support of these structural funds. The social and economic conversion is done in such a way that areas are provided with different developing opportunities, which help them in developing and advancing themselves and their areas. (Evans, 1999) Another objective was regarded in the structural funds of the European Union. In this regard, education, employment, as well as, the training systems and policies of the European regions are adapted and modernized by the support and coordination of the structural funds and their different planning and implementation of different projects in these areas. In all these three objectives, the transport sector has been specifically given a significant importance in the funding of these structural funds by the European Union. However, outside the specific areas of the first objective of the structural funds, the fisheries sector is also being restructured by the implementation of a special scheme. In addition, the European Union is witnessing the implementatio

Rebellion or Revolution Essay Example | Topics and Well Written Essays - 1000 words
Rebellion or Revolution - Essay Example In this paper I will take a specific position on the two concepts and aim to define each one of them. There have been numerous revolution and rebellions in the past. There has been confusion to some extent in terming an event a rebellion or a revolution. Numerous authors, researchers, historians, have all tried to establish a difference between a rebellion and a revolution. In the following paragraphs I will attempt to establish the difference between the two by taking a specific position on each. In order to do so, I have fallen back on the work of other scholars and some real life examples from the past. First, I will define each of them individually and then try to establish the difference between the two. According to me, a rebellion is an act of protesting or defying the higher authority. In most cases rebellion is a protest or against an ideology, requirement or a restriction. Through a rebellion, an attempt is made at changing a part of a system (for example part of a governme nt). A rebellion is always associated with a negative attitude if not a destructive one. Rebellions lack a proper direction and in most cases lack an affirmative program. Rebellion in most cases is associated with violence. Brinkley (2010) in his article points how to rebellion attitude is associated with negative emotions. But a rebellion is not always violent and negative. But a rebellion is an aggressive attempt to walk away from the routine and the accepted. Rebellion is a fight against the flaws or loopholes in a system that is accepted by majority of the society. It is aimed at changing or refining a part of the system. Rebellion is not associated with majority of the population but is supported only by a few. Hence, the scale of a rebellion is small. A rebellion unlike the common belief can be both violent and non-violent. Example of violent rebellion is rebellion against the Gaddafi government in Libya. A very good example of a non-violent rebellion is the protest by Gandhi against the injustice SA against the Indians. This is very well depicted in the 1982 movie Gandhi (Gandhi, 1982). This is will addressed again later. A revolution on the other hand is much larger in scale and is aimed at overthrowing the entire system or bringing in a major change in the way a system works. A revolution is associated with a positive attitude and is supported by majority of the society. As a result of a revolution there is a fundamental change being brought about with respect to power in a system. Revolution is mainly associated with political change and is much shorter with respect to duration but on a much bigger scale than a rebellion. A revolution brings in a major reform and attracts huge support from different quarters of the society. World has seen numerous revolutions in the past which has resulted in a total change. A revolution can be both violent and non-violent but it is always associated with positive emotion. Russian revolution was a violent revolution which bought a major political change in Russia while the Indian independence movement was a non-violent revolution which got India freedom. Now that the definitions and concepts of the two have been established, let’s see how they are different from each other. To put in a simplest way, revolution is born put of a rebellion. Rebellion is on a smaller scale and is aimed at showing discontent about the system while revolution is aimed at completely overthrowing a system. Rebellion is a narrow domain while revolution is a much broader field. A rebellion becomes a revolution when it gains momentum and realize its capability to bring in change on a large scale. A rebellion can happen at a individual level and might consider individual interests or interests of a small section of the society. Rebellion attitudes are

Legislative Requirements Essay Example for Free
Legislative Requirements Essay The purpose of this assignment is to identify the key aspects of current legislative requirements and codes of practice for teaching within the animal care sector. As a teacher within the establishment, it is my responsibility to ensure that none of my students are disadvantaged, by taking into account the Equal opportunity legislation, formally known as the Equality Act 2010, which came into force on the 6th October. It states that â€Å"no one is to be discriminated against irrespective of age, ethnic origin, gender, race, nationality, disability or domestic circumstances†the Equality act also replaces the Disability discrimination act. It would be my responsibility as a teacher, to ensure that any resources such as handouts and other learning material are free from bias (Wilson 2008 Pg 21 chap 1). Being in part, a vocational course, the health and safety at work act 1974 would be a key legislative requirement, as an educator I would be expected to demonstrate a model of best practice for my students to look up to and follow, subsequently, The management of Health and safety at work regulations 1999 would also be another piece of legislation which would be particulary relevant Furthermore, as an educator by law I have a duty of care towards my students, the legislation states that as teachers if you are proven negligent, you may have to compensate the injured party, not only does this apply to individuals but the organisation as well, I would have to ensure that whilst providing learners the opportunity to experiment and develop independence, it would have to be achieved in a safe working environment. Reporting of injuries diseases and dangerous occurrences 1995 is also relevant, being an educator in a potentially hazardous environment, more commonly known as RIDDOR, and states that certain incidents are reportable by law, they must be reported to the health and safety executive and the local authority, An example of this being if hospital treatment is needed to be administered to a student following an activity, the educational establishment should have clear guidelines on how to report incidents. There are numerous legislative requirements which as an educator I would have to adhere to. Wilson (2008) states that whilst some of these aspects need only awareness of context, many of them will impact on your first teaching experience, therefore require a detailed knowledge.

Parents Should Be Involved in Their Children’s School :: Argumentative Essays
There are many reasons that parents should get involved in their children’s school. Students who have concerned and involved parents tend to get better grades. When a parent asks questions about homework and assignments, supervises to make sure that they get done, and even helps with homework, it is more likely that assignments will be completed and handed in on time. Another factor in grades is attendance. With a low attendance rate, assignments will be missed, and the student will get behind in content as well. Parents who do not get involved in the school might not know that their child is not attending on a regular basis, or even care if their child goes. When children are first starting school, or transitioning from pre-school to elementary school or elementary to middle school, the transition is easier when parents are involved. If a child is unhappy about being in school, but their parents volunteer in the school, the child will see their parents there and be less upset because they will not be separated from them. For whatever reason, if a child is nervous or simply misses his or her parent, seeing the familiar face in the hallway or just knowing that they are in the building is comforting and makes the transition into school easier. Along with parents helping with homework and supervising that projects are completed, giving support to a child will make them more likely to pass from grade to grade. Without parent involvement, unless a child is self-motivated to go to school and do their work, it will be difficult to pass to the next grade level, and in time, graduate. When students see that their parents are involved in their school, it shows them that their parents care about their education. This sets a good example for the student, and they are likely to model their parents and believe that education is important and beneficial. This is especially true when students see their parents volunteering in their school. In order for a child to see their education as something important, they have to believe that their parents feel the same, especially at a young age. Reasons Parents Don’t Get Involved Sometimes parents do not get involved in their child’s education for a completely different reason than not caring.

American Poet: Phillis Wheatley Essay -- African American Poet Poetry
American Poet: Phillis Wheatley Phillis Wheatley was an African-born slave in the last quarter of the eighteenth-century in New England. She was born in West Africa and brought to America on the slave ship Phillis. She was, however, much more than chattel-she was a poet. Phillis was the first African American to have a book published. In a time when women were not expected to be able to read or write, and when teaching an African American to be literate was frowned upon, Phillis Wheatley became educated in Latin and English literature. The education of Phillis Wheatley was, for the most part, for the intent of training "a servant and would-be companion for domestic utility," in which they undoubtedly succeeded. However, they "got an intellectual adornment" who, with her knowledge of the poems of Alexander Pope, the "Puritanical whiteness of her thoughts," and ability to write poems, soon became a celebrity among Boston?s social elite (Richmond 18,19). Phillis's published her first poem in 1767, only a few short years after her initial introduction to the English language. Between the time of the publication of her first poem and her first book, Poems on Various Subjects, in 1773, Phillis gained notoriety by publishing elegies in New England newspapers; her most famous elegy being that for a popular Methodist minister, Reverend George Whitefield in 1770. Although Phillis?s poetry was well received throughout New England, there were people who did not believe all of the poetry was actually written by Phillis. Her expertise with the heroic couplet form perfected by her literary hero Alexander Pope and the allusions to classic Greek and English poetry caused the speculation. In order to prove the validity of her poetry, Joh... ...iterature. New York: Norton, 1997. 165-167. O?Neale, Sondra A. "Phillis Wheatley."

Abnormal Psychology in the Media Essay
The film â€Å"A Beautiful Mind†(Grazer, 2001) tells of the true life of John Nash, a Nobel Prize winner who has struggled the majority of his life with paranoid schizophrenia. This essay will evaluate John Nash’s exhibited behaviors, and how therapists from the 5 perspectives of abnormal psychology would have treated his illness. At the beginning of the movie â€Å"A beautiful Mind†(Grazer, 2001), John Nash is moving into a dorm room at Princeton University in 1947. John Nash appears slightly strange by exhibiting social withdrawal by avoiding people, along with a drop in school performance as he does not attend his classes. Soon visual hallucinations become apparent as Charles; his roommate makes appearances with his niece Marcie throughout the movie, along with Parcher, the head of the Department of Defense, who appears later in the movie as John Nash’s hallucinations become worse. John Nash begins to believe that he is employed by the Department of Defense, deciphering secret codes from the Soviets. As John’s hallucinations peak, he is admitted to a mental hospital under the care of Dr. Rosen, who diagnoses him with advanced schizophrenia. During the hospital stay, John received Thorazine injections, rendering him unconscious. John is seen during his stay at the hospital restrained to a chair, as well as a bed. During the time that he is restrained to a bed, Doctor Rosen is seen administering insulin injections, resulting in seizure activity as John’s wife is viewing the procedure through a window. Doctor Rosen tells Johns wife, Alicia that John must have insulin therapy several times a week in order to get well. Once John has returned home, he is seen taking two pink tablets several times a day. John appears to be keeping to himself while trying to deal with the effects of his medication; he decides to stop taking it without anyone knowing. Soon Alicia discovers that John is again having hallucinations of working for the department of defense requiring John to return to Doctor Rosen. After John resumes his medications, he begins to realize that Charles, Marcie and Parcher are not real. John goes to his friend Martin, who is in charge of the math department at Princeton University, asking for permission to sit in classes in order for him to get back into society which results in John gaining a teaching position after learning to deal with his illness by ignoring his hallucinations. The five perspectives of abnormal psychology are: biological, psychodynamic, humanistic, cognitive, and sociocultural. The biological model of abnormal psychology â€Å"focuses on genetics, neurotransmitters, brain changes, and other physical factors†(Kearney, C., & Trull, T., 2012 Pg. 23). Treatment through this model would begin with a â€Å"diagnostic interview along with images of the brain structure from an MRI†(Kearney, C., & Trull, T., 2012, Pg. 25). After these evaluations, a therapist would decide on the treatment necessary to treat the disorder such as therapy, social training skills, vocational rehabilitation, and medications. John Nash would possibly be given dopamine which â€Å"generally has antipsychotic effects easing the symptoms of schizophrenia†(Kearney, C., & Trull, T., 2012, Pg. 25) and therapy. According to Saul McLeod (2007) the biological approach believes that most behavior is inherited and has an adaptive function. Biological factors such as hormones, chromosomes, and the brain have significant influence on behavior, in the case of John Hall having schizophrenia; biological psychologists believe that levels of dopamine are the cause (Pg. 6). The psychodynamic model of abnormal psychology â€Å"focuses on internal personality characteristics†(Kearney, C., & Trull, T., 2012, Pg. 25). Treatments from this perspective would begin with a â€Å"therapist exploring the patients past for unresolved conflicts†(Kearney, C., & Trull, T., 2012, Pg. 30). â€Å"Other treatments would be the use of free association, or dream analysis†(Kearney, C., & Trull, T., 2012, Pg. 31). In John Nash’s circumstance, the psychodynamic model therapist would be looking into his past for the answer to his hallucinations. According to Laura Saunders (2011) the goal of the psychodynamic model therapist is to enable the patient to gain access to their repressed ideas and conflicts encouraging them to face up to whatever emerges from their unconscious (Pg. 1). The humanistic model of abnormal psychology â€Å"focuses on personal growth, choice, and responsibility†(Kearney, C., & Trull, T., 2012, Pg. 23), that â€Å"Assumes the person’s behavior is determined by perceptions of themselves and others†(Kearney, C., & Trull, T., 2012, Pg. 33). The humanistic models treatment begins with â€Å"qualitative assessments to find out the unique characteristics of the client, and their perceptions of the world. The therapist will then engage the client in conversations so that the client can develop solutions to their problems†(Kearney, C., & Trull, T., 2012, Pg. 34). Treating John Nash with this type of therapy would include conversations about his hallucinations in order for him to develop his own solutions. According to Kendra Cherry (2013) therapists from the humanistic model of abnormal psychology are focused on the individual’s potential and stress the importance of growth and self-actualization. The fundamental belief of the humanistic model is that people are innately good and that mental and social problems result from deviations from natural tendency (Pg. 1). The cognitive-behavioral model of abnormal psychology â€Å"focuses on specific thoughts and learning experiences†(Kearney, C., & Trull, T., 2012, Pg. 23). Treatment from the cognitive-behavioral model would include a â€Å"functional analysis, evaluating antecedents and consequences of behavior, followed by cognitive-behavioral therapy to change patterns of thinking and behaviors that are contributing to the patients problems†(Kearney, C., & Trull, T., 2012, Pg. 38), and â€Å"exposure treatment, which involves directly confronting the patients problem, or token economy, which reinforces certain behaviors with rewards†(Kearney, C., & Trull, T., 2012, Pg. 39), which John Nash, would possible be involved in, earning points for positive behaviors, and attending therapy. According to Jean Galica (2013), the cognitive behavioral model is an approach designed to change mental images, thoughts and thought patterns in order to help the patient overcome emotional and behavioral problems. This model is based upon a theory that behaviors and emotions are caused in part by cognitions and cognitive processes that the patient can learn to change (Pg. 3). The sociocultural model of abnormal psychology focuses on â€Å"external environmental events and includes the family systems perspective†(Kearney, C., & Trull, T., 2012, Pg. 23). Therapy within this model would consist of an â€Å"assessment of the patient’s culture, family structure, dynamics, and environment in order to understand the person’s mental health†(Kearney, C., & Trull, T., 2012, Pg. 44). As therapists from this model focus on addressing the patients problems in order to decrease or prevent stress, along with having family and couples therapy in order to include multiple family members into the therapy†(Kearney, C., & Trull, T., 2012, Pg. 44). Within this model, John Hall would have attended both individual therapy as well as couples therapy with his wife. According to Sheila Grant (N.D.) therapists from the sociocultural model believe that abnormal behavior may be found in the failures of society rather than from within the person, and that psychological problems can be rooted in requiring the therapist to look deep within the person’s relationships and social life (Pg. 7). This writer feels that the biological method of abnormal psychology is the best to treat John Nash’s schizophrenia since it â€Å"focuses on genetics, neurotransmitters, brain changes, and other physical factors†(Kearney, C., & Trull, T., 2012, Pg. 23). Along with the fact that treatment begins with a diagnostic interview containing MRI brain images (Kearney, C., & Trull, T., 2012, Pg. 25) before a treatment plan for schizophrenia would begin. According to NIMA.Gov (2013) it has been long known that schizophrenia can be inherited, that there are several genes associated with the disease (Pg. 1) resulting in treatments being based upon eliminating the patients symptoms by using medications such as: â€Å"antipsychotic medications to help normalize the biochemical imbalances, controlling hallucinations, delusions and confusion, along with supportive therapies†(Grohol, J., 2011, Pg. 1).

If the visit is a success and we learn about a local enterprise including products and services offered, the use of ICT in the business and health and safety procedures followed we will have achieved our first aim. . If we find out about the current strengths, weakness, opportunities and threats of KPW then we will have achieved our second aim. 3. Working as part of a team will help me improve my communication and organisational skills. Collecting the correct amount of money for the bus fare and lodging it to the office will help me to improve my mathematical skills. I will ask my LCVP teacher to access my communication and organisational skills at the end of the visit.
A Property of the Clan Essay
I have chosen to explore the theme of Peer Pressure from the text â€Å"A property of the clan†and the film â€Å"Thirteen†. In â€Å"A property of the clan†peer pressure plays a major part in the unfortunate events that unravelled within the play. This is most evident in the scene, when no one knew what had actually happened that night of the party, except those who had committed the act, and Jared. Page 28, Jared confesses to Ricko that he had witnessed the raping of Tracy that night at Black Rock.But Jared had not said anything to anyone as those who committed the felony, were in fact his friends. Jared tells Ricko â€Å"It's a madhouse. Davo and them running round saying don't be a dobber, and then the posters on telegraph poles. Shame Black Rock Shame. †This cleary portrays peer pressure as he feels as though he needs to refrain from telling the truth, to not be labelled a snitch. And he is put under more pressure considering the fact that they are his friends, and he believes that he cannot go against them, even if it is the right thing to do.After Jared tells Ricko what he had saw, Ricko gets defensive and tells Jared to keep his mouth shut. â€Å"Forget you even saw it. Nobody knows you were there. It's just the way things happen. †. Jared respons with â€Å"All right! †This represents peer pressure as Jared is put on the spot and being hassled not to tell anyone what he had seen. Jared's response with â€Å"All right! †shows him giving into peer pressure and is listening to what they are telling him to do. Powerlessness is shown in this scene by the main character Jared, as he is the vitim in the situation.This is shown mainly with the use of language techniques. For instance, page 31, â€Å"Not a word. Not a name. Not a single fucking name. Get it? †says Ricko. The use of slang and cursive lauguage by Ricko portrays aggressiveness toward Jared, putting Jared in a powerless state as he liste ns and just goes with it, not saying one word. Also, this use of launguage portrays Ricko's assertivness and puts Jared in a state where he cannot do anything about it, and that he has to listen to him. He is powerless in the situation.My poster promotes peer pressure through visual techniques such as juxaposition. This is evident as in the background, the people are positioned close together as a group, to show isolation and power over the main image of the girl. Also the use of colour is simple but eye-catching as it creates the focal point (girl) due to the contrast in colour (black and white). This layout portrays how in the play, Jared is left to decide for himself, whether he should do the right thing, or stick by his peers. Peer pressure also plays a huge role in the film â€Å"Thirteen†.Tracy (7th grader) becomes friends with the most popular girl in school, Evie, and is introduced to drugs, alcohol and sex. But Peer pressure was first and most evident when Tracy firs t hung out with Evie at a popular clothing store. Tracy shockingly witnesses Evie and her friend stealing clothing and accessories but steps outside the store as she knew it was wrong, and was laughed at and looked down by them. She had a moment to herself and thought about what had just happened. Ironically, a woman then sat next to her, and put her purse down. Tracy had a thought to herself.And only moments later, reunites with Evie, showing the wallet she had stolen and all the money that was inside. Evie's attitude toward Tracy was flipped and was then happily welcomed by her. This shows a form of peer power as Tracy is felt unwelcomed and as if she weren't fitting in, leading her to feel pressured into stealing aswell. Both power and powerlessness is shown by the main character Tracy in this scene. Powerlessness is shown through the technique juxtaposition, as Evie and her friend are always positioned close together, where as Tracy is always by herself ; portraying power over T racy.But at the end of this scene, when Tracy decided to steal the purse, she was welcomed by Evie and the use of up-beat music showed power as they walked happily together; ending the scene. Again, my poster promotes the theme of peer pressure through visual techniques such as colour. The colour of the people in the background are coloured in a shade of black, to contrast with the main image of the person in the foreground, to represent isolation and power over her. Also, the gestures made by the main image, (e. g. er stance and facials) show the feel of uneasiness in the situation, as she is under pressure by her peers. This contrasting image reflects how in the film, Tracy felt powerless and also uneasy about the situation she was in, but eventually gave in due to her peers. To conclude, peer pressure is clearly present in both the related texts â€Å"A Porperty of the Clan†and the film†thirteen†. Peer pressure is an inevitable part of life, which everyone wi ll evetually encounter; And these both these texts show the consequences of such.

Analytical Report on the core reasons for the dilution of the Assignment
Analytical Report on the core reasons for the dilution of the Singaporean spirit in youths and for them being uncomfortable in t - Assignment Example The most recent estimates place foreigners claiming at least 40 percent of the Singaporean labor force and more than a quarter of the 5 million residents registered in Singapore. (Chong 2010, p. 145) This phenomenon is not entirely surprising and is actually demonstrated in the experiences of countries who have adopted the same strategy – that of actively attracting immigration and pursuing foreign workers. The resulting multiculturalism and plurality in their respective societies have generated problems especially for native citizens. The seemingly universal consequence of this phenomenon is explained by the following perceptions: It is believed that the influx of foreign immigrants would mean less political and economic opportunities for the native citizens; Immigration erodes traditions and a nation’s way of life; Language and other cultural artifacts are endangered; Immigration would lead to a lowered quality of life, low standards in education, and so forth. (Hirsc hman, Kasinitz and DeWind 1999, p. 394) Most of the concerns that have been outlined above are actually valid. For instance, the sheer number of foreign residents in Singapore can hold hostage the government with regards to some policy issues by simply refraining to work. An excellent example is when a group of 100 Bangladeshi migrant workers gathered outside Singapore’s labour ministry, protesting for the release of their severance salary. (Reuters 2009) The protesters were not arrested and no further reports were made as to what the government did especially given the fact that Singapore has strict laws against this kind of activities. Writing for Temasek Review, a Singaporean, Fang Zhi Yuan (2010), questioned this development, stating: â€Å"Singaporeans will be wondering why the foreign workers are not arrested for assembly in a public area which can potentially lead to social unrest and disorder while the government and media often kick up a ruckus over a couple of loca ls committing the same deed.†The political consequence of having a sizable number of constituents that come from elsewhere is indeed a threatening prospect for Singaporeans. This is also true in other areas such as the economic and cultural. The prevailing opinion is that these mass of foreign workers brought with them an equally sizable coterie of customs, beliefs, culture, point of view and so forth that could potentially clash with the native’s own. On the other hand, it is also important to underscore that some adverse reactions and perceptions towards immigration or the government’s policy to invite more foreign workers are misplaced. For instance, there is the myth about the damage to economic opportunities for Singaporean. As Senior Minister Goh Chok Tong, in his speech at the NTU Students Union Ministerial Forum last October 2010, foreign labor is crucial in the overall health of Singapore’s economy. Then, there are also the misconceptions about m ulticulturalism.

Quistclose trust and the requirements for its creation Essay
Quistclose trust and the requirements for its creation - Essay Example It is whether his conduct renders him liable for having assisted in a breach of trust.†Lord Millett in Twinsectra Ltd v Yardley and Others [2002] 2 AC 164 at paragraph 52. Definition of a Quistclose trust A Quistclose trust is created when a creditor extends a loan to a debtor with the condition that the money lent should be used for a particular purpose. In commercial parlance, a Quistclose trust is â€Å"a means by which a lender of money can retain a ‘security interest’ in loan moneys only for specified purposes†.1 If the money is used by the borrower for a purpose other than that specified in the loan agreement, a trust is then imposed on the money in favour of the lender. How this works in the lender’s favour is best appreciated at such instance that the borrower is rendered insolvent. During insolvency or bankruptcy proceedings, the insolvent borrower’s estate is distributed according to the procedure specified by law. If a trust were no t created on the loan amount, then the creditor who extends such loan is an unsecured creditor, and his claim on the borrower’s assets will be included and classified among the other claims from other creditors. It shall therefore be settled pursuant to the hierarchy of claims, of which such unsecured loans have a low priority and may remain unsatisfied due to insufficiency of the estate.2 On the other hand, the Quistclose trust creates a security interest on the loan, meaning that such may not be distributed in the insolvency proceedings from the borrower’s remaining estate. Even if the borrower is not rendered insolvent after the loan is contracted, the lender retains the right to recover the loan amount, even to trace the loan money into the hands of third parties to whom it was given in breach of the loan contract.3 First Issue: Nature of the Quistclose trust and the requirements for its creation The Quistclose trust (from the judgement rendered in Barclays Bank Lt d v Quistclose Investments, Ltd. in 1970) gives rise to several legal requisites: (1) It is important to precisely identify the sort of â€Å"security interest†the lender acquires. (2) It is important to know whether the lender â€Å"retains†a right in the original loan moneys throughout the life of the loan contract, or whether the right is created for the first time only at such time the borrower disobeys the terms of the loan contract, or whether the right comes into existence in some other ways. (3) It is important to categorize which kind of trust the Quistclose trust is – whether it is an express trust, resulting trust, constructive trust, or another type of construct. (4) It is important to consider how the precise terms of any loan contract alter the appropriate analysis on the facts of any given case.4 The difficulty with defining Quistclose trusts in terms of the foregoing is that Quistclose trusts are created by operation of law, arising out of any situation involving a loan where the creditor insists that the borrower use the money only for a stated purposes, in a manner which seems to imply that the borrowed sum is not at the borrower’s free disposal. If this were the case, then the determination of the three certainties of express trust (intention, subject matter and objects) which would normally justify a finding that a trust existed, would have to be proved. As it is, in finding that a Quitclose trust existed from the mere intention

Film Art Essay Example | Topics and Well Written Essays - 1000 words
Film Art - Essay Example While Zombieland may exist in the kitsch horror genre, the film can be analyzed with the same critical tools as more artistic films. This essay examines a portion of Zombieland to consider the way elements of mise-en-scene, cinematography, editing, and sound combine to help the viewer understand the complete film. A film’s mise-en-scene is perhaps its most comprehensive element. Mise-en-scene is a French term referring to everything that appears on the screen.1 There are a number of prominent mise-en-scene elements in the clip from Zombieland. From an overarching perspective one considers that the entire film world has been altered as a means of establishing the post-apocalyptic environment. In this way there is minimal order. There are overturned cars in many scenes. Businesses are depicted as ransacked. In addition to these atmospheric elements, these scenes establish many of the narrative concerns that will be featured throughout the film. For instance, in one scene the mise-en-scene contains a football field, a man running, and a zombie running after the man. These elements are used to establish the importance of escaping zombies. In another scene the film displays an individual sitting on a bathroom stall. In this scene, mise-enâ€â€scene elements are combined with sound noises to create suspense and horror. A medium-range shot establishes the individual sitting in the bathroom stall. Loud zombie noises are then heard, before the individual is finally attacked by a zombie. Another major film element is cinematography. Cinematography is the movement of the camera capturing the film.2 This specific scene makes great use of cinematography. The opening shots feature an upside-down car. The camera is then turned upside-down as a zombie enters the screen. The next major scene is a long-shot the world. This long-shot of the world demonstrates to the viewer how large-scale the zombie problem has become, as it is clear that the

Successful Employee-Volunteer Programs and Its Benefits Assignment
Successful Employee-Volunteer Programs and Its Benefits - Assignment Example Therefore, for an EVP to be considered effective it must have the following features: First of all, it must have a plan. Effective EPVs have clear and attainable goals with specific strategies, focused efforts to achieve them. This can be achieved through an annual retreat of all EVP members to deliberate on an annual plan that will include goals, strategies and priority programs. Initial planning allows members to create backup plans in case the main strategies falter; this reduces time wasting that may occur when a program is hurriedly rushed into without prior planning and a problem occurs, where the members have to deliberate, look for funding, set up new strategies and designate duties to members. Secondly, the programs must have some level of measurement. This is to ascertain whether they have been accomplishing their plans in the past or not. The measurement should also include the effects of the programs on communities they are imposed on. Are they bringing joy to the people? Or their effects are not felt by the people. For instance, if it is proven that less volunteer hours is the main culprit behind poor results, then the company can create incentives to encourage employees to participate more on volunteer work, such as higher monetary rates for extra hours. An effective EVP must also embrace the design of the company. Since the volunteers are from the company, the way they are perceived by the public will mirror back to the company. It is therefore imperative that the workers portray the company well in terms of behavior and physical appearance. They should adorn new and improved gear with the company’s logo and positive and encouraging messages. Socially adept individuals should be the ones interacting with the people and working concurrently with them. Their quieter and less social peers should concentrate in areas with less social experiences. The volunteering should be a happy

AIRLINE BARGAINING PROCESS Essay Example | Topics and Well Written Essays - 2500 words
AIRLINE BARGAINING PROCESS - Essay Example The labor agreement includes various basic procedures which are truly essential to be followed by the unions. According to the report on Aviation sector it has been advised that the â€Å"unions must not agree to long-term concessions but rather to define measures on a short-term basis.†A tentative labor agreement calls for improved wages, job security and increased productivity and details a mutual commitment to labor partnerships and commitment towards employers. The election of the arbitrator should be done by both employer and union. The union and the employers have to go by the final decision taken by the arbitrator. The bargaining agent should be certified by the labor board as it represents all workers in the bargaining unit and negotiates a collective agreement with the employer. Once certified the union then has the legal right to represent all employees in the unit. The bargaining units determine the group of workers who are a part of the union, who are considered by the labor board as an appropriate group to bargain and those who are covered by the same collective agreement. The bargaining unit must pay union dues whether or not the members of the union. Collective bargaining is the negotiation between a union and the employer for a collective agreement. Breaching it leads to various unhealthy labor-management relations. But â€Å"currently there is no centralized bargaining forum in the Aviation industry†. The changed law of â€Å"privatization for workers has also led to various strikes†placing â€Å"excessive demands on the unions and fragmenting worker solidarity†. Such work rules are affecting labor-management relation to a lot.

Texas Science Scholars program Essay Example for Free
Texas Science Scholars program Essay Mrs. Page, I would like you to know that I do not consider English as one of my strongest subjects; however, I still am excited to be in this class. From what I can tell, your particular style of instruction will definitely be helpful towards my education in literature. I feel you are someone who can help me to better myself in writing. My name is Michael Cortinas. I will be majoring in Computer Science and I am currently part of the Texas Science Scholars program. I enjoy reading, but struggle when it comes to writing on a designated prompt. In high school, I was part of both the varsity track, and cross-country team. Before college, I would run two or three miles every morning, but, because all my classes take place in the morning, I haven’t had time. I have been working part-time at H-E-B for nearly a year now, where I do anything from cashier to push carts. I currently live with my mother, step-father, and three younger siblings, meaning most of my homework will be done on campus. When it comes to college, I hope to obtain the skills necessary to become an impact in my community and in the lives of those close to me. I feel if I can get enough from college, I can be the type of person that people feel confident in putting their trust and coming to for advice. I guess this desire was inspired my great-grandfather, who passed away last year. He was someone that everyone felt comfortable confiding in and always seemed to know just what to say. Your class, being one that works with word choice, is a great start towards this goal. I feel that I am going to enjoy your class and all it has to offer.
Analysis of Docker Technology
Analysis of Docker Technology What is the technology? Docker is a software containerization platform. What does it do and how does it improve upon previous technologies? Docker allows users to run multiple different software packages, including multiple instances of the same piece of software within an isolated virtual container. The behaviour and features are similar to that of running a virtualized operating system, such as allowing isolation from the host machines operating system, the ability to run multiple instances of the same software package simultaneously and the storage of applications in a format that can be transferred between physical machines. Traditional virtualization hypervisors such Hyper-V, ESXi and Xen all rely on each virtualized instance to have their own complete operating system, drivers, libraries and software packages to be installed and running. Docker moves away from this method and instead provides an abstraction layer between the host operating systems kernel and the containerization application. The containerized applications are configured to share the same operating system and libraries. This removes the overhead of running multiple instances of these items reducing system resource utilization. In addition to the performance benefits, Docker maintains the security features provided by virtualization hypervisors. Docker containers are configured to use virtualized network interfaces allowing segregation, VLAN tagging and inter-container networking amongst other features. The Docker container files are self-contained allowing them to be transferred freely between different physical hardware without the need for reconfiguration. This has also led to multiple repositories of Docker containers to be created, allowing the public to upload and share pre-configured open-source software packages. How might it transform computers and devices using it? Tell us some scenarios. By converting from using a traditional virtualized operating based configuration, end users can increase the utilization by running more software on less physical hardware. This in turn will reduce hardware, energy and other related costs and improve efficiency when deploying new software instances. Web hosting services could increase the amount of services existing hardware could provide and increase efficiency when deploying new services. For example, each WordPress installation could be configured in individual containers while accessing a shared SQL database, rather than each installation requiring a full virtualized operating system to be deployed per instance. Software developers can also take advantage of Docker to assist with their development and deployment cycles. Software can be configured and optimized on developers local machines or development servers and be easily transferred to quality assurance teams and finally to production environments. Why is it interesting and important? Docker is an important step forward from traditional virtualization technology. The software has been developed under the open-source Apache License 2.0 allowing anyone to take part in development and to also freely use and modify any components for their own project both personal and commercial providing they follow the licensing requirements in their scenario. By consolidating existing infrastructure energy emissions will be reduced, reducing the carbon footprint of users. Other consumables used in certain operations can also be reduced, such as water in server farm cooling configurations and physical space used allowing more compact configurations. Management and maintenance of software packages can also be improved. If issues are found with particular software version updates, providing the previous container is kept the singular application can be rolled back rather than the entire operating system. What is the device? Ring an IoT connected doorbell What does it do? How would you use it? Tell us some scenarios. Ring is a doorbell with an integrated camera, microphone, speaker, motion sensor and is internet connected via WiFi. By connecting the doorbell to the internet it is able to alert the user via a smartphone app when the doorbell is rung or the motion sensor is triggered. The user can then check the video feed from the door, to determine who is at the door. In response, the user can then choose to activate the speaker function to speak with the person at the door using the smart device, similar to that of a traditional intercom system. The device also saves its video recordings to a cloud service allowing the footage to be viewed anywhere using a compatible smart device. The device can be used in a number of ways. If the user is expecting a parcel and is not at the address at the time of the delivery, they will be alerted on their smart device when the doorbell is rung. Once the user is alerted via their smart device, they can then activate the video feed to confirm who is at the door and then use the speaker to advise the courier to leave the parcel in a safe location. Home security can also be improved by using the device. The video recording functionality will be triggered with any motion near the front door, even if the doorbell is not rung. This footage will then be stored off-site via a cloud storage service. In the unfortunate event of a break in, the intruder will be unable to destroy the footage, which can then be used to assist authorities in subsequent investigations. In addition, some insurance providers may offer reduced insurance premiums when such devices are installed. Briefly outline the devices interesting software/hardware/networking. In what way does computer technology transform or realise the device? Ring is provided with a mobile application that allows the doorbell to be paired with the users iOS or Android based mobile device. The doorbell has an integrated WiFi adapter which is used to connected to the users home WiFi network to provide internet access to the device. This allows the doorbell to provide notifications to the smart device application regardless of if the user is at home on the same network or are located elsewhere, provided they have access to an internet connection. The doorbells integrated motion sensor and camera add further functionality previously not possible. The camera used has been selected for its low-light performance, in combination with infra-red LEDs to provide illumination to the recorded footage without any light being visible to the human eye. This enhances its ability to be an inconspicuous security device. Recorded footage is saved off-site using a cloud storage service. This is used by the mobile application to provide the user with the ability to watch footage while away from their local network and to provide an archive solution without requiring a large amount of local storage. Why is the device an interesting or important example of embodiment? As defined by Professor Tony Hey in his book The Computing Universe: A Journey through a Revolution Butler Lampsons third age of computing is about using computers for embodiment that is, using computers to interact with people in new and intelligent ways This is shown through the Ring doorbell, in the way it allows the user to connect with the outside world in a new way. It provides the user the ability The ring doorbell provides a new way for users to connect with the outside world. It removes the need for a person to be home to accept parcels, it tracks motion which can provide the user with a greater sense of security at home all through the adoption of technology. Week 2 What are the devices? Device 1: Smartwatch Device 2: PC Characterise the computing requirements of the two devices? Device 1: CPU A smartwatch requires a CPU(Central Processing Unit) to process all machine instructions provided by applications and the operating system. Most smartwatches use an ARM architecture CPU. Bluetooth Bluetooth is a networking protocol used for the smartwatch to communicate with the host device (usually a smartphone). NFC NFC (Near Field Communication) is a networking protocol used for communicating with external devices. This is commonly used in contactless payment systems GPS GPS (Global Positioning System) is geolocation system used to provide location data to the device. This is commonly used for maps and navigation systems Battery A custom made lithium-ion battery. Used to provide power to all the components in the device. To recharge the battery either a port is provided to connect the watch to a power source or wireless charging is implemented to provide from a wireless power source Display A display is used to provide visual interface for providing information to the user. Touch interface A touch interface (Also known as a digitizer) is used to allow the user to interact with the smartwatch by touching on the display. Touch screens are commonly used due to the limited space on a smartwatch for other methods of interfacing with the device, such as buttons. RAM RAM (Random Access Memory) is required for the CPU to store data while is processing instructions. RAM is volatile memory and is not used for persistent data storage. Persistent Storage Persistent storage is required to store the operating system, applications and user data. This is commonly a form of NAND flash memory due, as it offers compact storage with no moving parts which could be damaged in a device that is moved during operation. Speaker Speakers are used to provide aural feedback to the user. Microphone A Microphone is used to receive aural data from the users, for example a phone call will require the Sensors There are numerous sensors located on a smartwatch that each monitor a different function.Most smartwatches have an Accelerometer to monitor acceleration, a Barometer to measure atmospheric pressure, a Gyroscope to measure the angle of the device, a Heart Rate monitor to measure pulse and an ambient light sensor to determine the backlight of the screen. GPU The GPU (Graphics Processing Unit) is used to accelerate the creation of visual elements. This is commonly integrated as part of the CPU in smartwatches due to size constraints. WiFi WiF is a networking protocol used to transmit data in a local network. This is used in a smartwatch to provide network connectivity when the host device (e.g. smartphone) is not available. Device 2: CPU A PC requires a CPU(Central Processing Unit) to process all machine instructions provided by applications and the operating system. Most PCs use an x86 architecture CPU. RAM RAM (Random Access Memory) is required for the CPU to store data while is processing instructions. RAM is volatile memory and is not used for persistent data storage. Persistent Storage Persistent storage is required to store the operating system, applications and user data. This can be a mechanical hard disk drive, utilizing magnetic platters to store data or a solid state disk which uses NAND flash memory to store data. Network Adapter A network adapter is required to connect the PC to a local network. This can be achieved through a range of interfaces including a wired ethernet connection or a wireless WiFi connection. Some systems will have both options available. GPU The GPU (Graphics Processing Unit) is used to accelerate the creation of visual elements. This can either be integrated into the CPU or can be provided through a discrete graphics adapter, for enhanced performance. USB Ports Power supply A power supply is required to convert mains AC power into DC power required to power the individual PC components. Some PCs (such as laptop computers) may utilize a battery to provide an additional power source Video Ports Audio Ports C.

Moores Law Why might Moores Law come to an end soon? Explain based on current technologies. Moores Law was originally conceived in 1965 when Intel co-founder Gordon Moore posted an article about microprocessors. In the article Moore observed that the number of transistors in integrated circuits doubles roughly every 12 months. After 10 years once more data had become available Moore updated his theory from 12 months to 24 months. Intels latest processors are built using a 14 nanometer manufacturing process, however production of Intels next generations of processors with 10 nanometer transistors has already been pushed back by a year. Intel have stated that this was not a one-off occurrence and that they are not able to continue to keep up with the rate they used to. This shows that Moores law is now coming to an end too. One main reason that Moores law slowing down and potentially coming to an end is that its not possible to continue to keep shrinking transistors, while maintaining a functional device at the rate that is required to continue improving at the rate theorized. As MOSFET transistors follows the principles of quantum mechanics, as the transistors shrinks it makes it harder to determine if it is in the 0 or 1 state. The electrons inside the transistor can travel through devices with little resistance, therefore as the transistors get smaller, the resistance also gets lower which eventually lead to quantum mechanical phenomenon described as tunnelling rendering MOSFET based transistors non-functional. https://www.technologyreview.com/s/601102/intel-puts-the-brakes-on-moores-law/ http://spectrum.ieee.org/semiconductors/devices/the-tunneling-transistor Discuss a new or future technology which might overcome these technological limitations. Instead of trying to find ways to prevent quantum tunneling in transistors, researchers are investigating a new transistor design called TFET or Tunneling Field Effect Transistors. This style of transistor is designed to manipulate when quantum tunneling occurs in a controlled manner. This allows for transistors to be produced at an even smaller scale than MOSFETS can be without quantum tunnelling becoming a negative side-effect. Another advantage of this technology is that has the potential to be implemented in place of MOSFETs without the need for technology that implements them to be completely redesigned due to the similarities between TFET and MOSFET transistors. http://berc.berkeley.edu/tunneling-field-effect-transistors-beyond-moores-law/ https://engineering.nd.edu/news-publications/pressreleases/more-energy-efficient-transistors-through-quantum-tunneling What might be the ramifications if Moores Law comes to an end or slows down? If Moores Law comes to an end or slows down, the rate at which processor performance improves will decrease. This would reduce the rate at which new technologies are developed and would slow innovation in field relying on technology. 3. Non Von Neumann Processors Investigate a non von Neuman processor such as a graphics processor, FPGA or signal processor. How and why is it different from a general purpose CPU such as you might find a phone or PC? An FPGA or Field-programmable gate array is a type of integrated circuit that can be digitally re-programmed after it has been manufactured, unlike for example, the logic within a microcontroller which is hardwired during manufacturing. This It allows the user to program custom digital circuits using hardware description language to suit their requirements. FGPAs are sold without any pre-programmed instructions and are instead sold based on the physical features of the FGPA such as how many logic gates or how much memory it has, making it a very flexible device. As FPGAs can be reprogrammed without any need to change the physical hardware, this lends them to being used heavily in development and prototyping environments. Developers can create and update the logic throughout the development process without the need to purchase new hardware each time a change needs to be made. This is different to hardware such as a x86 CPU which cannot be reprogrammed and only supports the provided instruction sets. http://download.springer.com.ezp01.library.qut.edu.au/static/pdf/116/bok%253A978-1-4302-6248-0.pdf?originUrl=http%3A%2F%2Flink.springer.com%2Fbook%2F10.1007%2F978-1-4302-6248-0token2=exp=1490752308~acl=%2Fstatic%2Fpdf%2F116%2Fbok%25253A978-1-4302-6248-0.pdf%3ForiginUrl%3Dhttp%253A%252F%252Flink.springer.com%252Fbook%252F10.1007%252F978-1-4302-6248-0*~hmac=b61cb59b461de816fe408c9ab730e0d9cd6ab12d55885171f66b3c880d9aafaa 3-5 Week 3 OS 1 IBMs z/OS IBM z/OS is a operating system designed to be run solely on IBM mainframe computers. Mainframe computers are large, high-end computers designed specifically for processing large amounts of data, often used by large organizations. IBM describe the key features of the z/OS operating system as its stability, security and high availability (IBM, 2014, para. 1). OS 2 Embedded Linux Embedded Linux is a term used to cover the Linux operating system being used on embedded computer systems. These embedded systems are generally very low-end computers, designed to run a very specific and minimal set of software that are then embedded inside another product, for example they can be found in some models of washing machine to offer further functionality. Linux is described as being flexible and open (Siever et al., 2003, p.1-3) which offers developers to ability to customize it to their exact needs and requirements. Comparison and contrasting Both of these operation systems are designed to run very specific types of workloads. The z/OS mainframe operating system is designed to process and analyse large data sets to provide in-depth insight on the data (IBM, 2015). The operating system is designed to handle very high performance workloads and to run as quick and efficiently as possible. Embedded Linux operating systems are designed to run a very specific workload such a smart TVs interface with as minimal overheads as possible due to the hardware restrictions of the low-power systems that are used in most Embedded Linux implementations (Simmonds, 2015, p.1-12). Both systems are designed to run specific processes, however the z/OS operating system is designed to run processes on high-end hardware on a large scale, whereas the Embedded Linux operating system is most commonly used on low performance hardware on a small scale. Open Source Software Security/Flexibility Open source software gives users the option to modify and adapt software to their needs. As the entire source code is publicly available and the software can be adapted, used within another software package or re-released as a different product, depending on the license type the original developer released the software under (Open Source Initiative, 2016). This also provides security to users, as they can audit the code themselves for security issues and if required patch the source code directly, rather than relying on a third party to find and resolve any potential issues. Cost Licenses for closed source commercial operating systems can range from a few hundred dollars up to thousands of dollars per installation (Microsoft, 2016). This can become very expensive for businesses that rely on a large amount of physical and virtualized operating systems. Open source software has no licensing costs associated with it, which can significantly reduce licensing costs, depending on the use case. This is also applicable to embedded platforms, which are generally designed to have a low cost per unit. Open source software can remove software and operating system licensing costs, helping to maintain a low cost per unit. Operating System Arch Linux a lightweight and flexible LinuxÂÂ ® distribution (Arch Linux, 2017) How are new features developed? New features developed in two main ways. The first of which is by the individual package developers, for example new features to the Netcat package will be developed by the Netcat developer community. Arch Linux package maintainers are then responsible for packaging new releases for the Arch Linux operating system and adding them to the Arch Linux package repository. The second way features are developed are by the Arch Linux developer team (Arch Linux, 2017). The features they develop range from developing and implementing software developed specifically for the operating system, to configuration and modification of third party packages and managing what packages are included and how they are used in the base operating system installation. How do new features make their way into a release? Arch Linux doesnt follow a traditional fixed release cycle, rather it employs a rolling release model (Arch Wiki, 2017) which allows individual components to be updated as soon as they are deemed ready. Packages are updated as soon as the maintainer has deemed the package stable and ready for release, after which it is upload and added to the repository. This model aims to remove the stagnation between fixed releases and instead aims to keep all at their latest releases. References: Arch Linux. (2017). A simple, lightweight distribution.

Week 4 Network 1 WiFi WiFi (also known as Wireless LAN or WLAN) is a network technology designed as a replacement to LAN cabling and is developed around the IEEE 802.11 specification. The IEEE 802.11 specification is the standard dictating the use of the 802.11 radio frequency that WiFi uses to transmit data wirelessly (Tjensvold, 2007). Within the 802.11 specification there are a range of protocols that have been developed, with the current standard being the 802.11ac revision. This specification has support for speeds over 1Gb/s, depending on the antenna configuration in use. The range of a WiFi signal is generally quite short at approximately 20-25 metres depending on obstructions. This makes it good for use in home and business environments where access points can be installed where WiFi signal is required, but makes it a poor choice for larger area networks, such as mobile phone data. WiFi power usage is split between the access point and the client receiving the data. The access point uses significa ntly more power to broadcast the signal than the client device needs to receive it (Zeng, 2014). The latency provided by modern WiFi specifications, such as the 802.11ac revision offers low latency communication between clients and access points. The exact latency the client will note, will be dependant on the band being used (either 2.4GHz or 5Ghz in the case of 802.11ac), obstructions and the amount of antenna in use on the access point. Security of WiFi networks is dependant on how they are configured. A basic home configuration using outdated security technologies such as WEP or WPA1 to authenticate users is at risk of unauthorized users gaining access to the network. WPA2 authentication offers a stronger level of security by implementing the AES-CCMP algorithm. WiFi networks can also be vulnerable to MITM (Man in the middle) attacks, where a potential attacker can attempt to spoof the WiFi network, which clients may unsuspectingly connect to which will then allow the attacker to see any traffic of the connected clients. The effectiveness of this type of attack can be counte racted by ensuring traffic is being transmitted over secure protocols such as HTTPS and SSH, which will render the intercepted data unreadable (Joshi, 2009). Network 2 Bluetooth 4 and Bluetooth Low Energy (BLE) Bluetooth 4 is a short range network technology developed by the Bluetooth Special Interest Group. Bluetooth 4 covers a range of specifications including Bluetooth low energy, Bluetooth High speed and Classic bluetooth. Bluetooth is used for short range personal area (PAN) and ad-hoc networks, primarily in portable devices such as smart phones. Bluetooth devices are classified into 3 classes, depending on the transmission power of the device and the intended usable range. Class 1 devices have 100 mW transmission power and are designed to be used at ranges of up to 100 meters, class 2 devices have 2.5 mW transmission power and are designed for use at up to 10 meters and class 3 devices have 1 mW of transmit power and are only usable at ranges of under 10 meters. Class 1 and 2 are the most commonly used types, with class 1 devices generally being used in desktops, laptops and other devices with a large battery or mains connected power supply. Class 2 devices are generally used in porta ble devices such as smart phones, IoT connected devices and wireless headsets. Class 2 still allows for a usable range while keeping power usage to a minimum (Wright, 2007). The Bluetooth specification has 4 different security modes in which devices can operate. The security mode in which the device will operate will be selected based on the Bluetooth standard in use on both devices. Bluetooth 2.1 and later devices have a mandatory requirement to use security mode 4, proving both devices support it. Service mode 4 forces encryption for all services, providing security for all communications except for service discovery (Padgette, 2012). Compare and contrast fibre optic and wireless technologies within the context of a National Broadband Network (NBN) for Australia. Fibre Optic (FTTP) The National Broadband Network (NBN) provides a range of connection types with fibre optic technology being utilised in multiple service types including fibre to the premises (FTTP), fibre to the node (FTTN) and fibre to the distribution point (FTTdp) (NBN, 2017). Fibre optic connections use a optical fibre cable that uses light to transmit data. This type of cable transmits data faster, further and with a lower latency than the traditional copper cable which transmits data by electrical impulses. As this technology relies on a physical connection to the premises it is not practical to utilize this technology for remote locations, however for areas with higher population densities supplying broadband via FTTP is more practical as the cost per premises is decreased and reduces load on wireless services. Fibre optic cable is not affected by signal degradation as significantly as copper cabling and is therefore able transmit data across long distances more effectively . As the cable transmits data by light pulses the cable is resistant to any noise and ground vibrations interrupting or degrading the signal. Fibre optic cable is also able to supply much higher bandwidth connections (Malaney, 2010), with NBN already offering 1Gbps products to service providers, although this product is not currently being on-sold to consumers due to factors including demand and pricing accordin
