See more: Foot Binding In China essay Usually what happen when we go through literature in our classroom either by ourselves or teacher use to teach one thing matters very much and that is the importance of literature for students. The first significant thing is the artistic quality of all literature. All art is the expression of life in forms of truth and beauty or in another word which exist in this world and which remain unnoticed until bought to our attention by some sensitive human soul same like the delicate curves of the shell reflects sounds and harmonies too faint to be otherwise noticed. In the same pleasing,surprising way,all artistic work must be a kind of revelation as architecture is probably the oldest creative work of arts and yet we still have many builders but few architects,that is,men whose work in wood or stone suggests some hidden truth and beauty to the human senses. It is a prevalent opinion that literature is like all arts is mere play of imagination,pleasing enough like a new novel without any serious or practical importance. Nothing could be farther from the truth, Literature preserves the ideals of a people and these ideal are love, faith, duty, friendship, freedom and reverence which are the part of human life most worthy of preservation. * To know the beauty of creation, to know about human evolution, to know the various cultures & civilizations, to be compassionate, to understand human values and concerns about other earthlings, to enjoy the fine art of writing, to learn how to express in simple words, to converse politely, to respect the ignorant and the learned, and so on. * Without literature there would be no reference to the past. 2. Define literature * (from Latin litterae (plural); letter) is the art of written work. The word literature literally means â€Å"things made from letters. † Literature is commonly classified as having two major forms—fiction & non-fiction—and two major techniques—poetry and prose. * Literature may consist of texts based on factual information (journalistic or non-fiction), a category that may also include polemical works, biography, and reflective essays, or it may consist of texts based on imagination (such as fiction, poetry, or drama). Literature written in poetry emphasizes the aesthetic and rhythmic qualities of language—such as sound, symbolism, and metre—to evoke meanings in addition to, or in place of, ordinary meanings, while literature written in prose applies ordinary grammatical structure and the natural flow of speech. Literature can also be classified according to historical periods, genres, and political influences. * Important historical periods in English literature include Old English, Middle English, the Renaissance, the Elizabethan era of the 16th century (which includes the Shakespearean era), the 17th Century Restoration period, the 18th century Age of Enlightenment, the Romanticism of the early 19th century, the later 19th Century Victorian, and 20th Century Modernism and Post-modernism. Important intellectual movements that have influenced the study of literature include feminism, post-colonialism, psychoanalysis, post-structuralism, post-modernism, romanticism, and Marxism. 3. What are the different general types of literature? *

In recent years Essay

In recent years, the selective and mobility promoting function of education has become more important than its socialising function` Do you agree? Explain I agree with the opinion that in recent years, the selective and mobility promoting function of education has become more important than its socialising function. While both these functions retain their importance, the selective and mobility one has received greater prominence. In the US, education has always been a gateway to professional life and a vehicle for social mobility. In a sense, this is a great advantage of the US society compared to those with traditionally rigid social structures since promotion to upper classes through education opens the way for those from low-income families to move up in their socioeconomic status relatively quickly. With years, however, educational institutions became a tool for sorting school graduates into those who qualify for professional careers and those who do not. Reliance on standardised tests has turned the US system of education into an institution that selects those fitting into the standards and gives them chances for social mobility. At the same time, the socializing function has become less important. Modern adolescents still seek to make new friends, to have cheerful college years. Their professors remind them that socializing is also important for social mobility, prompting them to build a network of acquaintances that will later contribute to their career. Thus, even socializing has been turned into a vehicle for social mobility. Students increasingly view their educational experience as a step toward career progress rather than a chance to gain friends or broaden their world outlook. This is visible, for instance, in graduate students’ aspirations to get into top MBA programs that many see as a gateway to high-salaried executive world. The main advantage of the top programs as compared to the rest, in the eyes of a large part of student body, is that they have sifted through applicants at the beginning, chosen the best ones and sent them off to high posts in business organisations. Socializing takes a second place in these considerations because students are mostly interested in career ambitions and see education as a way to realize them.

Cultural Imperialism Essay Example | Topics and Well Written Essays - 3000 words

Cultural Imperialism - Essay Example Since media plays a vital role in the cultural lives of millions of people and the fact that media sector is by and large controlled by Western interests, there have been arguments in favor of the idea ‘cultural imperialism’. Although the central postulate of cultural imperialism thesis remains valid due to the lopsidedness in the global media market, the so-called cultural imperialism through the Western cultural products cannot be seen as one sided as the theorists of cultural imperialism perspective understood it to be. In the light of the recent developments taking place in the media sector, especially the regional media in the developing countries and the changes bought by the new media technologies, this paper intends to present the basic theoretical tenets of cultural imperialism and the challenges to it from various perspectives. The core concern of the essay is to examine what is remaining relevant with the arguments and concerns regarding cultural imperialism a nd the criticisms provided by the contesting theoretical doctrines from the vantage point of the tremendous transformations occurring with the global media culture from the very beginning of twenty first century. Explaining Cultural Imperialism The widespread availability of American cultural products such as music, television channels, entertainment and informational commodities is one of the important factors that enable the lopsided influence of American culture over the rest of the world. Therefore, Schiller famously defines cultural imperialism as "the sum of processes by which a society is brought into the modern world system and how its dominating stratum is attracted, pressured, forced, and sometimes bribed into shaping social institutions to correspond to, or even promote, the values and structures of the dominating centre of the system" (Schiller, 1976: 9). Importantly, Schiller (1969) has found a common ground between the study of media dominance and theories of economic imperialism. For him, it is necessary to look at theories such as world systems and dependency theories in order to explore the dynamics of domination in the sphere of communication. For Schiller, it is nothing but the viability of American indu strial economy that furthers "the movements towards international commercialization of broadcasting" (Schiller, 1969: 9). And, hence, the enhanced spread of cultural imperialism. On the economic realm, the proliferation of American products has a penetrating impact over the determination of the cultural aspects of the lives of millions of people from outside the United States. Many theorists have almost equated cultural imperialism with American cultural imperialism as if the United States alone is the conductor of the concert of global cultural imperialism. What is important to note that there is no single culture that alone oppresses other cultures. With reference to the nation state as the overwhelming reality in the modern world, it is possible to classify cultural imperialism as cultural imperia

Social Media and the Affects on Personal Relationships Research Paper

Social Media and the Affects on Personal Relationships - Research Paper Example Such a framework of ethics is especially important in a scenario where there is a world where multiculturalism is an important part. In such an environment, it is important that there are many ways in which people from all over the world are able to understand the methods that are used by one another at least at the virtual plane that social media exists at. This is then an important part of the entire enterprise of social media and its use by people of a particular organization. The paper shall look at the ethics of politicization of media and the role of social media within this. It shall also look at how personal relationships are affected by all of this. Relationships between customers and sellers have been fast changing as a result of social media. In traditional approaches to the ways in which customers and the people who used to sell commodities and services interacted, there would often be a system that would enable consumers to talk to the managers of their companies and the managers would then be able to talk to the consumers. This would be different in a modern setup as the consumers are able to talk to each other through social networking sites (Mangold and Faulds, 2009). They are able to communicate with each other the problems that they may face in dealing with the managers of a company. This would alter the paradigms of the relationships between the consumers and the managers of the company. Apart from this, it would also alter the paradigms of the relationships between the different consumers of the same product. This would then need to adhere to certain norms of ethics to lead to a constructive process. Rules of professionalism need to be adhered to even in such circumstances. If not, there would... This report approves that relationships between customers and sellers have been fast changing as a result of social media. In traditional approaches to the ways in which customers and the people who used to sell commodities and services interacted, there would often be a system that would enable consumers to talk to the managers of their companies and the managers would then be able to talk to the consumers. This would be different in a modern setup as the consumers are able to talk to each other through social networking sites. There are plenty of such websites that are willing to provide information free of cost to people who wish to access it. This then becomes a point where several people from different parts of the globe can converge and possibly even, through an exchange of information regarding places, build persona relationships. This can then point towards a situation where people from different parts of the world can form bonds merely on the basis of knowledge. One then see s the importance of knowledge and an ethical and honest use of it within the space of social media for it to be constructive for it users across the world. This essay makes a conclusion that political relations between people too form a part of the matrix of personal relations that people form amongst themselves in the society. This then points to the role that social media plays in the creation of political relationships between people. Clay Shirky talks of the different roles that are played by forms of social media in creating new forms of political relationships in the world. Shirky attributes the development of political awareness to a certain extent to social media and the different forms of it

Listening, Learning and Communication Essay Example | Topics and Well Written Essays - 1500 words

Listening, Learning and Communication - Essay Example There is such a thing as ineffective communication, which instead of creating a fine relationship with others, it creates tension between people who are trying to create connection with their fellowmen. This is where communication roadblocks enter the discussion. These roadblocks are usually encountered because of the differences of each human individual. It could be noted that because of the differences of each person, the receiving and giving of message through words and action between people may not be that common enough to easily understand. Within the paragraphs that follow, the said twelve roadblocks shall be discussed clearly as based from the sensation, perception and attention practice that had been performed by the author of this paper. The roadblocks mentioned earlier could be identified to fall into three major divisions. These include judging, sending solutions, and avoiding other's concerns. These three divisions are then subdivided into few more 12 subsections. At some point, these destructive procedures of communication at times happen when two persons are in a discussion that is involving problems or personal troubles. Because of the tension that is usually built up due to the problem being talked about, the sense of right reasoning is usually lost because of the lack of understanding that exists due to the tension. To be able to understand everything, the twelve roadblocks should be discussed herein in a clearer pattern: Judging Criticizing This is the way by which a person intends to manipulate the thinking of the other person through questioning the attitudes of the other. Not only that, the situation usually aggravates the questioning of the attitude of the other towards the other person. Robert Bolton comments on the matter saying: "Many of us feel we need to be critical, or other people will never improve we make a negative evaluation of the other person, for his or her actions, or attitudes." (Burtis, 2005, 18) The attitude of man to even aggravate the situation being faced by the other because of some emotional attachment to the issue makes this particular roadblock an effective way of stopping or heating up a particular conversation. Name-calling At some point, when people get pissed off because of a heated conversation, they tend to course the other or at times they name-call the others with insulting titles that makes it hard for the other party of communication to understand clearly what is happening. The result then leads to a more aggravated heated conversation. Bolton further adds, "Name calling and labeling usually have negative overtones to both the sender and receiver. Labeling prevents us from getting to know ourselves and other individuals." (1999) Diagnosing At some point, when people argue over something, they become too much sensitive with how the other reacts upon a certain situation or how a person intends to talk back to them. The sensitiveness results to diagnosis of the reaction of the other and the way of speech that he or she uses within the conversation. Instead of simply listening to what the person says, reading between the lines becomes another way of decoding the bodily message of the person who is speaking. Another comment from Bolton reads: "We analyze

Do Annual Financial Reports have to be so lengthy and cluttered Essay

Do Annual Financial Reports have to be so lengthy and cluttered - Essay Example According to a recent report by Deloitte, many of the larger firms have reports that are more than 309 pages in length. Companies disclose their business risks, the key performance indicators, and these disclosures are in response to the EU Transparency Obligations Directive. A few areas that lead to clutter are immaterial disclosures, needless explanations that prevent the reader from understanding important information. Other areas for clutter are long explanations given as declarations and footnotes that do not change every year. Other examples are detailed notes online items, share-based payments and so on. These are included more as behavioural influence from the previous years. Accountants fear comments from regulatory agencies that the reports do not disclose all the required information and hence they include a number of declarations and narrations about even minor items. Other areas that lead to excess clutter is information on corporate social responsibility, deferred tax, directors’ report and statutory information, financial instruments, intangibles, principal subsidies, movement tables, post-retirement benefits, principal risks and remuneration report.... Other examples are detailed notes on line items, share based payments and so on. These are included more as behavioural influence from the previous years (Campbell and Slack, 2008). Accountants fear comments from regulatory agencies that the reports do not disclose all the required information and hence they include a number of declarations and narrations about even minor items. Other areas that lead to excess clutter is information on corporate social responsibility, deferred tax, directors’ report and statutory information, financial instruments, intangibles, principal subsidies, movement tables, post retirement benefits, principal risks and remuneration report (Holmes, et al, 2008). One of the most abused areas that have excessive clutter is the Corporate Social Responsibility section. Many firms, such as BP and Wall-Mart, actually devote more areas on providing information and high gloss pictures on the CSR activities than they do for the actual financial reporting (Kindle berger and Aliber, 2005). While the information given in this section is entertaining and helps to understand that the company does social work also, the large volumes of information, data about various committees, sub activities, and so on do not help an investor to allot resources or to understand the health of the firm (Humpherys, et al, 2011). Another area that sees the most clutter is the section on governance. The UK Corporate Governance Code has 52 provisions but firms can show compliance to only 18. In the annual report, the firm can demonstrate how it has complied with these 18 codes. For the remaining codes, it can give the number and state briefly the reason for non-compliance. However, many

How did the rise of the corporation affect the United States What Essay

How did the rise of the corporation affect the United States What factors helped corporations form, and - Essay Example The strategy gave rise to big businesses that led to fewer people controlling the market. The presence of machines for agriculture made the United States pioneer in productions of agricultural products. The rise of the corporations transformed the United States because its economy matured (Sauvant, Mendoza & Irmak, 2008). During this time, there was a rapid expansion of big business and the rise of national labor unions. Despite all positive effects, the rise of the corporations led to the rise of wars against Americans and the removal of indigenous people from their early homes. The rise of corporations led to the growth of the population in urban centers. It also enhanced the proportion of immigrants. The most affected individuals lived in the urban centers due to the need to expand agricultural fields (Sauvant, Mendoza & Irmak,

Elasticity of demand Essay Example | Topics and Well Written Essays - 500 words

Elasticity of demand - Essay Example e behavior of price elasticity under monopolistic competition, oligopoly, and monopoly to determine the differences in price elasticity among the economic structures. Under monopolistic competition the price elasticity is high. One of the reasons this occurs is because there are many firms competing in the marketplace. Firms can enter easily into this market structure because there are no barriers of entry. An example of a firm operating under monopolistic competition is the fast food giant McDonalds. It is clear for customer that the prices between fast food chains change a lot based on the price moves made by others. When McDonalds introduced its one dollar value menu, competitors in the industry such as Burger King and Wendy’s followed with an economical menu of their own. The intense competition in under this market structure raises the price elasticity of demand for its players. In an oligopoly market structure the price elasticity of demand is medium. An oligopoly market is one in which there are a limited number of firms participating in the marketplace. Since there is competition the price elasticity of demand is affected by others. There are barriers of entry which limit the number of participants. The price elasticity of demand is lower in monopoly than in monopolistic competition since it now in the best interest of the participants for price wars to occur. Many fluctuations in price among participant in the market can be very damaging to the entire market structure. An example of an oligopoly is the airline industry. Airlines can not go in full price wars since their activities are interconnected as far as sharing resources from airports and the firm know the aggregate demand for flying is somewhat stable, thus a price war will only lower the total profits of all the participants in the market structure. The economic profits of firms participating in an oligopoly depend on the other players which lower the price elasticity of demand. A third market

Environmental web portal Essay Example | Topics and Well Written Essays - 750 words

Environmental web portal - Essay Example An environmental web portal can serve as scientific as well as educational purposes for the community that uses its information. It provides a platform whereby resources, information, and experts in environmental science can converge and exchange ideas.Moreover,it will create an online opportunity for researchers to further their fieldwork and establish a bridge between class work and field work The web portal is aimed at enriching its information through accepting contributions from people visiting the site like the inclusion of a video blog, data collection, equipment operation and different observations from site visitors (Popovic, Lindic, Stemberger and Jaklic, 2005). The portal will form a basis of scientific research and verification of data through engaging in discussions and other activities that enhance environmental awareness. Environmental Web Portals host research, lesson plans, and online coursework, monitor student outcomes, and satisfy the reporting standards established. The environmental science projects require people to establish common grounds through which they can share knowledge and join efforts to solve environmental problems. The areas of interest include pressures of urbanization, information management and ensuring information accessibility to both the research hers and to those visiting the web portal.The environmental web portal will enhance both live and recorded online presentations of data and will enable visitors to understand how field equipment and other equipments are used in the process of data collection and analysis. In addition, the environmental portal will have a clear indication of the research funded by the government, its achievements and challenges. A clear description of the investment in people, the equipment to be used and the relevance of the research and how it is bound to affect people’s lives will be highlighted. Through the environmental analysis, the portal can be developed using basic technologies and helps in the achievement of tasks like development of online communities, administrators and environmental experts. Properly designed portals can act as effective communication tools that can enhance adoption of best practices in the environmental conservation campaigns. Availability of the environmental documentaries online enables constant updating on the latest research findings like discovery of new species, those facing extinction and effects of climatic change on the survival of organisms. According to Popovic, Lindic, Stemberger and Jaklic (2005), rapid technological and environmental changes pose new challenges to researchers and environmentalists that have been tasked with the responsibility of explaining the changes and recommending the desired course of action. The government aims at building an environmental research infrastructure to necessitate the adoption of environmental research data management. The Atlas of Living Australia (ALA) and the Terrestrial Ecosystem Research Network (TERN) were structured by the government and given the responsibility to initiate an environmental monitoring network. The Institute of Sustainable Resources (IRS) received funding from the Grains Research Development Corporation

Step By Wicked Step by Anne Fine Essay Example for Free

Step By Wicked Step by Anne Fine Essay The setting for the story Step by Wicked Step is one dark stormy night when five schoolchildren on a school trip stayed in a towering mansion. They found secret tower room that was hidden behind a wall. The lights in the mansion were not working and they has to depend on the streaks of lightning and the moonlight for light. The tower room, covered in a coat of dust, had not been used for a long time. There were heavy drapes, plain dark coverlet and frame old maps. A dusty green album revealed the story of Richard Clayton Harwick’s journal entitiled† My story, Read and Weep. Following this each one of them related their own sad story of their broken homes and relationship with their family members.

Richard related the story of his life with his stepfather and he ran away to escape his problems. All the five children symphatised with Richard’s situation and they each has their own sad tale to tell. The setting enhances the plot of the story by providing the atmosphere for the story. The tower was dark except for flashes of lightning and later the moonlight. It gave the children the mood and courage to tell their story. The dust in the room symbolized their past which should be wiped away so they could look forward to a brighter future. Write about difficult decision made by one of the characters The novel Step by Wicked Step is about five schoolchildren who found and read Richard Clayton Harwick’s journal of his life with his stepfather and his running away from home. The five children were inspired to tell their own sad family stories of broken homes. In the story, Richard Clayton Harwick made the difficult decision of running away. Richard Clayton Harwick felt sidetracked by his father who made him promise to look after his mother and sister after his death. His father made no reference to him. He was disappointed and to make matters worse, his mother remarried. His stepfather Mr. Coldstone or the ‘black, black bat’ as Richard referred to him imposed very strict rules on Richard, to the extend that he felt his home was more of a prison. He was sent to Mordanger School where he spent ‘four long years’ and it was a place of bad memories. He was extremely unhappy in his own home, a place where he had such a good memories of his father. He was disappointed that his mother did not seem to want to make any effort to protect him from his stepfather. Richard decided to run away from home. He felt that the three of them, his stepfather, mother and Charlotte would be happier without him around. His mother would find life more pleasant, Mr Coldstone would be pleased and Charlotte would not miss him. I think this was wrong decision as his decision changed three lives for the worst. His mother died of heartbreak, his stepfather of fury while Charlotte probably of childbirth. I feel he should have stayed on and tried to get along with his stepfather for his mothers’ sake. He should have let the past go and kept the happy memories of his father instead of feeling and showing unhappiness all the time. As Charlotte told him just because life had dealt them one hard blow, there was no reason fro them to be unhappy forever. His decision to run away was not right decision as it caused too much sorrow.

Richard came from a happy family unit until his father passed away and his mother married to Mr. Coldstone, somebody Richard could not get along well with. He felt that he did not belong to his family, his mother and his sister anymore. While Cahrlotte got along well with their stepfather, Richard could not and did not want to. So, he decided to run away, thus breaking off family relationship with them rather than bear the unhappiness of bad family relationship. The five schoolchildren coming from broken homes had to deal with stepparents, stepsiblings, and half siblings. Some accepted these relationships well other could not. Most of the time they pretended to be amiable for their parents’ sake. When matter came to head, some like Claudia and Pixie sorted to out their feeling with their stepmothers. They were thus able to rebuild their family relationships. Others like Callie, Robbo’s sister, preferred to run away from their problems. The common thing about them was they felt their opinions and feelings did not count with their parents. Family relationships should be built on understanding and parents should take into account children’s opinion, especially on the issue of family relationship.

The glycerol formed with ATP in the presence of glycerol Kinase forms Glycerol 3 Phosphate which is oxidized by the enzyme glycerol phosphate oxidase to form hydrogen peroxide. The hydrogen peroxide further reacts with phenolic compound and 4-aminoantioyrine by the catalytic action of peroxidase to form a red coloured quinoneimine dye complex. Intensity of the colour formed is directly proportional to the amount of triglycerides present in the sample. The intensity of chromogen (Quinoneimine) formed is proportional to the Triglyceride in the sample when measured at 505nm (500-540nm). Preparation of working Solution: Allow the reagent bottle and AQUA-4 to attain room temperature .Add the amount of AQUA-4 indicated on the label to the contents of each vial.

SOD Activity= Normal range: 12-16 unit/mg protein 3.7.2 Estimation of Ceruloplasmin activity in serum/plasma: At pH 5.4, ceruloplasmin catalyzes the oxidation of PPD to yield a colored product, which is believed to correspond either to Bandrowski’s base or to Wuerster’s red . The rate of formation of the colored oxidation product is proportional to the concentration of serum ceruloplasmin if a correction is made for nonenzymatic oxidation of PPD. Therefore, simultaneous assays are carried pH 5.45, which has been warmed to 37 ºC.The contents of the flask are adjusted to pH 5.45 at 37 ºC by dropwise addition of sodium hydroxide solution (1 mol/liter), and diluted to the mark with acetate buffer solution. The solution is stable for3h. Procedure (1) Into two test tubes (12 X 75 mm), labeled R (reaction) and B (blank), 2 ml of acetate buffer solution was pipetted.

Opto-Electronics for Communications: Spectrum Analysis

Opto-Electronics for Communications: Spectrum Analysis This experiment studies the wavelengths of the colours in the spectrum of a light source. I will measure the angle at which colour splits. I will carry out this experiment with three different light sources: Tungsten LED Laser Diode Light Source Spectrum The electromagnetic spectrum describes all the wavelengths. It ranges from the smallest waves possible, radio waves to the largest waves, Gamma radiation. All different size waveforms have different uses. Energy Frequency Wavelength Radiation type Typical use Lowest Lowest Longest Radio waves Television signals Microwaves Cooking, mobile phones Infrared Optical fibre communication Visible light Seeing Ultraviolet Detecting forged bank notes X-rays Medical images of bones Highest Highest Shortest Gamma radiation Killing cancer cells The only Electromagnetic waves we can see are Visible Light Waves. We see visible light waves as colours of the rainbow. Each different colour has its own wavelength different to the others. The longest wavelength is Red, with the shortest wavelength being Violet. The combination of all the light wave colours makes white light. Diffraction We can see each colour of the Visible light spectrum by shining a white light through a prism. By diffraction, the white light splits apart into different colours of visible light. Water vapour can carry out the same effect of diffraction, and the result is a rainbow. Gratings A diffraction grating is a slide with a number of parallel slits drawn on it. The slits are very small, usually 600 per 1mm. When a beam of light is directed at the grating, light will diffract of it and the light is dispersed in certain directions only. This is commonly used to separate colours of the incident light because the diffracted light has different angles according to: All equipment used for this experiment was taken from the PASCO Educational Spectrophotometer Accessory Kit Rotary Motion Sensor Aperture Bracket Light Source PASCO data acquisition software High Sensitivity Light Sensor Equipment Setup Set up the Spectrophotometer next to your chosen light source as shown in Figure 2. Mask the light source with Collimating Slits so it transmits a thin 0.5 to 1.0 cm beam. A hood should be used over the light source to remove any distortion in the experiment results. Align the light source. Turn on the light source and align the light beam by adjusting the Collimating Slits, Collimating Lens and Focusing Lens so a clear image of the central ray appear on the light sensor. Connect the Light Sensor and Rotary Motion Sensor to channels A and B of the PASCO computer interface. Software Setup Open the PASCO data acquisition software. Connect Digital channels 1 and 2 to the Rotary Motion Sensor. Connect Analog Channel A to the Light Sensor. Set up parameters for the Rotary Motion Sensor. A sample rate of 20 Hz with a high resolution of 1440 Divisions per Rotation. Use the PASCO softwares calculator function to calculate the Actual Angular Position based on the Angular Position measurement made by the Rotary Motion Sensor. The measured Angular Position should be divided by 2à Ã¢â€š ¬. Data Recording Setup In the PASCO data acquisition software, select the graph mode. Select the vertical axis as Light Intensity, and Horizontal axis as Actual Angular Position. Turn off the lights in the laboratory to ensure the results are as accurate as possible and no background light interferes. On the top of the light sensor select the appropriate gain setting. Different light sources will require different settings. Select Start Recording Data Turn the light sensor slowly in one complete circle. This will scan through the first order spectrum lines and data will be recorded in the PASCO data acquisition software. Select Stop Recording Data Data Analysis Setup The size of the wavelength can be calculated by analysing the results of the experiments and using the gratings equation. By using a visible light spectrum, we can determine what colour the light is from the size of the calculated waveform. Wavelength Measure the two peaks, R1and R2 Use the visible light wavelength spectrum below to find out what the wavelegth is Tungsten Light Source Dating back to the 1800s, Tungsten light sources are the oldest and most tested light source invented. They first became commercialised by Thomas Edison at the end of the century, leading on to the first light fittings, named after Edison himself. The Edison Screw or ES. A Tungsten filament is the key element to a Tungsten light source. Light is emitted from the filament when it is heated. The filament is heated by passing current through it. This is possible because of the high amount of current passing through such a small conductor. Inert gas such as Argon usually surrounds the conductor to ensure that it does not ignite. 95% of the energy from a Tungsten light source is wasted in the form of heat. Only 5% of the energy is actually used in the form of visible light. This makes it a very inefficient light source. Being a blackbody radiator, a Tungsten light source has a continuous spectrum of light. It generates a high amount of red light compared to natural day light, which gives it the yellow tint. Beyond the visible light spectrum a Tungsten light source even emits infrared wavelengths. This is a waste of energy as it cannot be seen by the human eye. On the next page are the results from the PASCO data acquisition software whilst carrying out the experiment procedure using a Tungsten light source. The light sensor was set to have a gain setting of 100 because of the large spectrum that the wavelength covers. Peak to peak wavelength: Infrared Waveform Trough to trough: Ultraviolet Waveform My experiment results show that the Tungsten light source is emitting wavelengths in the range of 317.88 to 895.14nm. The Tungsten light source is a warm white light as well as Infrared and Ultraviolet light. LED Light Source A LED or Light Emitting Diode is a semiconductor that gives out light when current is passed through it. It is a much more efficient method of emitting light compared to more conventional light sources such as Incandescent lights or Fluorescent lights because less heat is generated, resulting in less heat loss. As well as being more energy efficient compared to Incandescent light sources, LED light sources have a much longer operational time. At the end of an Incandescent lights life the filament will burn out, resulting in the bulb not emitting light. A LED light source after 50,000 hours of use will start to become dimmer and emit less light. The result of this is a light source that lasts a lot longer. The first commercial LED light sources developed were by Hewlett Packard in 1968 to replace indicator lamps. At this time, only LEDs emitting red light were available. Only later on in 1994 were LEDs that emitted blue light first demonstrated by Isamu Akasaki and Hiroshi Amano, who went on to be awarded the 2014 Nobel Prize in physics for their discovery. With the invention of blue coloured LEDs, the invention of white LEDs became apparent. The white LED is a combination of LEDs that emit red, green and blue light. This then led to the LED light source revolution we currently live within. The working principle behind a LED is what is called a P-N Junction. A P-N junction will convert electric current into visible light. This is often called electroluminescence. Colour Wavelength (nm) Typical Material Used Infrared > 760 Gallium arsenide Red 610 to 760 Aluminium gallium arsenide Orange 590 to 610 Gallium arsenide phosphide Yellow 570 to 590 Gallium arsenide phosphide Green 500 to 570 Gallium phosphide Blue 450 to 500 Zinc selenide Violet 400 to 450 Indium gallium nitride Ultraviolet Indium gallium nitride White Broad Spectrum Cool white is a blue LED combined with a yellow phosphor. Warm white is a blue LED combined with a orange phosphor. Table 1: Wavelengths of each colour LED Above is a table outlining the individual wavelengths for each colour that is produced by Light Emitting Diodes. The most common type of LED light source shines line in a single direction. The result of this is a light bulb that only lights up a small area. To correct this problem for use as light sources to light up areas and not as indication lights, most LED light sources are coupled with reflective plates that distribute the light evenly around the room. On the next page are the results from the PASCO data acquisition software whilst carrying out the experiment procedure using a LED light source. The light sensor was set to have a gain setting of 100 because of the large spectrum that the wavelength covers. Peak 1 Peak to peak wavelength: Yellow Waveform Trough to trough: Green Waveform Peak 2 Peak to peak wavelength: Blue Waveform Trough to trough: Blue Waveform My experiment results show that the LED light source is emitting visible light in the ranges of 388 to 473nm and 514 to 583nm. The LED is emitting a combination of yellow and blue to create a cool white colour. White LED By combining yellow and blue waveforms, a cool white colour is formed. This is carried out by lining a blue LED with yellow phosphor. Both yellow and blue photons are emitted. This method of creating white light is much more effective than the more conventional LED RGB method of combining red, green and blue waveforms. This effect was discovered by Sir Isaac Newton in the early 1700s when he was performing colour matching experiments. The colour temperature of the white LED light source is controlled by the thickness of the yellow phosphor that is coated onto the blue LED. Over time, the yellow phosphor will degrade and so the colour characteristics of the LED light source will change. Operating at high temperatures can accelerate this. Laser Light Source Laser is an acronym of Light amplification by simulated emission of radiation. A laser light source emits light when electrons in the atoms of gases become excited by absorbing energy from electrical current. Electrons travel from the lower energy point to the higher energy point around the atoms nucleus. When they travel back from the higher point to their resting state the electrons emit visible light. The wavelength of the photons emitted are constant and coherent, unlike ordinary visible light from other light sources. This means that only one wavelength of light is emitted from a laser light source, resulting in only one specific colour. Also because of this, the light is not diffused like a conventional light source. The light emitted is a very tight beam. The result of this is a beam of light that can travel much further than other light sources. By harvesting the narrow powerful light, laser light sources have various applications such as: Entertainment Laser light shows are created by bouncing different lasers into each other to create special effects Computing Lasers can be used as a form of communication due to the high speed of light. The most common application is fibre optics. Production Due to the high amount of energy concentrated in a laser light source, they can be used in production to cut a range of materials. Optical Fibre Communications Information in the form of coded light of infrared signals are carry across Optical Fibres. The information carried across Optical Fibres can be much more than an ordinary copper data cable of the same diameter. An optical fibre is a very thin shard of glass. Next to no light is absorbed by the glass. Light is carried from one end to the other by total internal reflection (TIR), even when the fibre is bent. The signals in optical fibres do not weaken as much over long distances as the signals in ordinary cables. The laser diode that is used for optical fibre communications is typically either 850nm, 1300nm or 1550nm. This means that the waveform used is in the infrared field of the electromagnetic spectrum. We use infrared because the attenuation if the fibre is less at infrared wavelengths. On the next page are the results from the PASCO data acquisition software whilst carrying out the experiment procedure using a LED light source. The light sensor was set to have a gain setting of 10 because of the small spectrum that the wavelength covers. Peak to peak wavelength: Red Waveform Trough to trough: Red Waveform My experiment results show that the laser light source is emitting visible light in the range of 624 to 690nm. The laser is emitting a red light. The overall results of the spectrum experiment look unique to each other. All three light sources have different spectra to each other. The Tungsten light source has a wide range across the spectrum covering all the visible colours, as well as ultraviolet light to infrared. The LED light source has a much smaller range across the spectrum compared to the Tungsten light source by only emitting waveforms that combine colours to create a cool white effect. The Laser light source had the smallest range on the visible light spectrum, only covering the colour red. This light source is much more concentrated on one area of the spectrum compared to the other light sources. From the results, I can see why each type of light source is used for its applications. Tungsten light sources cover all colours within the visible light spectrum, and so they are good for illuminating objects, in the form of a light bulb. LED light sources only cover specific colours within the visible light spectrum, and so they are good for indication lamps and signals. Laser light sources only cover one area of the light spectrum and therefor used for communications. Laser diode light sources are the key piece of equipment for optical communications because of the small wavelength that they emit. This small wavelength can be interpreted as data signals and used as optical communications. The overall results of this experiment where great. The result were exactly how I predicted them to be. If I could change anything about the experiment, it would be the Tungsten light source. I would use a larger light source as the Tungsten light source used was not very effective during the experiment.

Odyssey Theme Paper :: essays research papers

The Odyssey Theme Paper   Ã‚  Ã‚  Ã‚  Ã‚  The Odyssey is mainly about the tribulations of a great hero; that hero would be Odysseus. Although Odysseus does not appear in this epic until the fifth book, he is still the main character. Odysseus, whom I will call the hero, has many tribulations in this epic. Read on to see what I mean.   Ã‚  Ã‚  Ã‚  Ã‚  This story starts right after the Trojan War; the Greeks have won, thanks to one of Odysseus’ great ideas. All the kings are now trying to get back home to their families. Odysseus, however, will have the most problems.   Ã‚  Ã‚  Ã‚  Ã‚  The first place Odysseus goes after the war is the land of the Ciconians. He and his men raid the island and destroy the village. However the next day, more Ciconians arrive and defeat Odysseus and his men. Several men are killed, and Odysseus experiences his first of many sorrows and tribulations. Next, the hero goes to the land of the lotus-eaters. Some of his men eat the lotus plant and instantly want to stay there and never leave. Odysseus manages to get his men away from the island, and they leave. Then the hero arrives at the home of Polyphemos. Polyphemos is a huge cyclops and also a cannibal. Odysseus and twelve of his men are trapped inside Polyphemos’ cave and can’t get out. Polyphemos comes back and eats some of the hero’s men. The next night Odysseus gets the cyclops drunk on wine, and when it falls asleep, Odysseus and his remaining men blind it with a large pole. He and his men barely escape with their lives and continue on the voyage. The hero soon lands on Aeolus’ island. (Aeolus is the Keeper of the Winds.) He helps Odysseus on his way by giving him the right winds to take him home to Ithaca. The hero gets within site of his home but a hurricane blows him all the way back to Aeolus’ island. This time Aeolus turns Odysseus away, and he is forced to continue his journey. The hero and his men next end up in the Land of the Midnight Sun, where the Laestrygonians live. The Laesrtygonians attack the men and sink eleven of the twelve ships. Only Odysseus’ ship and forty-four men escape to safety. This is one of the most painful tribulations Odysseus faces on his journey. Soon afterwards, Odysseus and his now small crew arrive on Circe’s island.

Fahrenheit 451 by Ray Bradbury Essay -- Literature Fahrenheit 451 Book

Fahrenheit 451 There appears to be some writing on the note ... Fahrenheit 451, by Ray Bradbury, is a science fiction novel that discusses and shows the life of a very controlled society. The society is not allowed to read books and is punished for doing so. The books are burned at 451 degrees Fahrenheit, which is the temperature it takes book paper to burn (Bradbury 1). Although society today isn't like that as far as books are concerned, the author still shows some trends that are occurring today. Some of the characters in the novel are similar to people in today's society in the way they act towards society's views. The society in Fahrenheit 451 is similar to the society in "Those Who Walk Away From Omelas," a story by Ursula LeGuin. Although the novel and the short story have a completely different plot and narrative, the themes and moral issues are similar. The society in the novel is a very controlled society as far as values and beliefs are concerned. The government has set rules and regulations that books are not allowed and will be burned if they are being read or seen by anybody. Instead of the fire department putting out fires, they are actually the ones setting the books on fire. The beliefs are forced into people's heads by television or the radio that books are bad and should never be read. Most of the people in this society listen to whatever the government tells them and believe that books are not good and will alarm the fire department if anyone is going against the rules. The people of this society are stuck in this matrix, or belief system, and they have no choice to get out, similar to the movie "The Matrix." They have to obey all the rules of the matrix perfectly or else they will be the "outcas t" an... ... today's society are similar to some of the characters in the novel. Fahrenheit 451 can also be related to some stories in literature because of the issues and themes it discusses. Both today's society and the society in the novel have certain rules that the people in the matrices are supposed to follow but the rules in the novel are less common and their punishments tend to be stranger and harsher. Whether or not these rules and beliefs are morally right or fair is a different subject, however, it doesn't seem fair to make the laws so strict without any flexibility. When doing this, there tends to be more rebellion, which is seen in the novel Fahrenheit 451. Works Cited Bradbury, Ray. Fahrenheit 451. New York: Ballantine Books, 1953 Kennedy, X. J., Dana Gioia.

Gender Changes In Popular Media Essay examples -- essays research pape

Gender Differences as Portrayed in LIFE Magazine from 1937-1960 Between the years of 1937 and 1960,LIFE underwent changes involving the portrayal of the genders. In popular literature, stereotypes and views of certain subjects are often displayed for future study. In the case of gender differences, advertisements and articles yield the best portrayal of gender stereotyping of the time. The following issues of LIFE magazine were used in this paper: January-February 1937, January-February 1945, January-February 1952, and January-February 1960. At the end of the Great Depression in 1937, women had a very simple stereotype in the popular media. They were portrayed as staying home, cleaning, cooking, and mothering. The only pictures of women in LIFE were of housewives doing some sort of domestic work. Men were portrayed exactly the opposite, out at social functions or at some sort of important occupation. One of the first ads in the magazine was an advertisement for Colgate toothpaste. It pictured a girl in college complaining to her roommate that no one likes her and she is quitting school, â€Å"I should have never gone to college†. She then goes to her dean to quit and realizes she has bad breath. The dentist gives her Colgate and soon she has a date for the prom. â€Å"I love college now.† This cartoon advertisement seems to imply that in 1937, women went to college to get married. Most of the other articles involving women were ones that involved housework. Every last one of the cleaning and food advertisements had a pretty lady in a dress holding the item. Moreover, if there was a man in the picture, he was either getting food at the dinner table or sick in bed with his wife nursing him back to health. All of these articles implied the same thing: women stayed in the house and took care of all the domestic activities. Some ads did portray women outside the home. One cigarette ad had both a man and a woman on it. The Camel man was a cowboy, watching his herd, the Camel woman was a pretty young secretary busy a t her typewriter. There was obviously a clear division of labor in 1937. Finally there was an popular art series exhibited in LIFE in January. The article was written about a series of murals painted of the depression. All the men in the paintings were working hard, carrying mailbags, building a house, farm work, and other hard labor jobs. The women were s... .... Less and less of the advertisements pictured women in a traditional dress. Also, while most of the articles in the previous issues had been about men, the 1960 issue was written as much about female accomplishments as it was about men’s. Concerning changes in male gender roles, one article titled, â€Å"New Roles in the Household† described instances of men tending to the house, cooking cleaning, and the kids, while the mother was out at work. In addition, one of the cover stories was of the US women’s Olympic ski team. Attitudes were changing by the early 1960’s. Women were not conforming to the past gender stereotypes. Instead, they were inventing a new one, which continues to further change today.   Ã‚  Ã‚  Ã‚  Ã‚  Gender roles changed a lot in this century and popular literature like LIFE magazine changed with it. At first women had a set role in the house, expected to tend to the house and children and not pursue careers of their own. Thirty years later men and women had changed the way they lived life as a gender. Popular magazine articles provided a good illustration of what we were like culturally seventy years ago, and how we have changed today.

Chad Foster’s “Teenagers Preparing for the real world” Essay

Chad Foster’s book Teenagers Preparing for the Real World, is a great motivational piece for teens and leaves a lasting impression on the reader. In the chapter â€Å"Mr. X and Mr. President,† Foster instills the importance of contacts and friendship in a person’s life. His example of Mr. X shows kids that a friendship formed in a person’s younger years can pay off greatly down the road, emotionally and even financially. He then tells the tale of his father’s first experience in the work world, where he met two men, had a brief friendship for a few months, then moved. Foster senior continued to correspond with these men for the next thirty years, never even seeing each other. As it turns out, one of these men was President George Bush and Foster had the opportunity to meet him in person. This story is significant because it shows that everyone grows up to be someone in the world, and someday you just might want to be their contact. Overall, this is a very well put together chapter and defiantly leaves an impression on the reader.

Unit 1 Assignment 1 Windows 2008 Network Services

Unit 1 – Assignment 1 – Windows 2008 Network Services If you have a routed local area network and high-speed links that are fairly reliable, you might be able to use one DNS server for a larger, multiple sub-netted network area. If you have a high number of client nodes on a single subnet design, you might want to add more than one DNS server to the subnet to provide backup and failover if the preferred DNS server stops responding.When determining the number of DNS servers you need to use, assess the effect of zone transfers and DNS query traffic on slower links in your network. Although DNS is designed to help reduce broadcast traffic between local subnets, it does create some traffic between servers and clients that should be reviewed, particularly when used in complexly routed LAN or WAN environments. Consider the effects of zone transfer over slower speed links, like those typically used for a wide area network (WAN) connection.Windows 7 Check Your UnderstandingAlth ough the DNS Server service supports incremental zone transfers and DNS clients and servers can cache recently used names, traffic considerations are sometimes still an issue, particularly when DHCP leases are shortened and, as a result, dynamic updates in DNS are performed more frequently. One option for dealing with remote locations on WAN links is to set up a DNS server at these locations to provide caching-only DNS service. With most installations, you should have at least two server computers hosting each of your DNS zones for fault tolerance.DNS was designed to have two servers for each zone, one as a primary server and the other as a backup or secondary server. When making any final determinations about the number of servers to use, first assess the level of fault tolerance you need for your network. Because there is no fixed limit to the maximum number of clients a DHCP server can service or to the number of scopes you can create on a DHCP server, the primary factors to cons ider when you determine the number of DHCP servers to use are network architecture and server hardware.For example, in a single subnet environment, only one DHCP server is necessary, although you may want to use two servers or deploy a DHCP server cluster for increased fault tolerance. In multiple subnet environments, routers must forward DHCP messages between subnets, so router performance can affect your DHCP service. In both cases, DHCP server hardware affects service to clients.

Social inequlity

We live in a world that is culturally diverse. Gender, sexuality, race, ethnicity are Just some of the diverse areas In society that are believed to be Important. In spite of these differences, we tend to centre ourselves round people who we can relate to In somewhat and those who are similar to us, If that being people who are the same status, share physical or biological traits or even have the same or similar lifestyle to us. Due to all this, it's in our human nature to be ethnocentric towards people who re different from us.This causes discrimination, which in time causes social inequality, something that is becoming very common in our society today. One of the noticeable areas of discrimination is race. Race refers to the biological characteristics of one; skin color, hair/ eye color, height etc. Related to race is ethnicity, which relates to the cultural factor such as nationality, ancestry, language, beliefs and culture. Both race and ethnicity can cause a big controversy all around the world, the controversy being racism.Focusing on Australia, the nation Is known or their warm welcoming to different races and ethnicities. Many people believe that Australia being so open to different cultures etc. Is a wonderful thing they tend to miss out on the racism that occurs. As with America, Australia represents a large percentage of racism towards different races all across. For instance; Indigenous people of Australia. These people are known to be the first people on Australian land, it's their land, so why all the hate towards them.Many indigenous are very disadvantage as they live In poor remote areas of all parts of Australia, when they are men by â€Å"white people†, they don't have a bad word to say, but as soon as the â€Å"white person† glances at them, racial abuse is Just heard. Indigenous sport players have encountered some on ground racism throughout matches, 1 993 saw SST Skill's Nick Winner responds to racists taunts from the oppositi on crowd by lifting his shirt, pointing to his skin and saying that his proud to be black.In another example of discrimination Is, the article Office work and crack alternative, Philippe Bourbons shows how a group of Puerco Rican Immigrants faced discrimination due to their ace, which resulted in deprivation of jobs at a range of work places and they were stereotyped as lazy and good for nothing people. Ethnicity has played a huge role in social inequality. The trust of one's own ethnic group(ethnocentrism) allows a system in which societies rank categories of people in a hierarchy ( social stratifications) creating inequality (Furze 2012).This all then results to all sorts of things, such as; personal insults (egg. Name calling), structural obstacles (egg. No loans). This can effect a person's physical and mental health which could then lead to harming oneself. ND gender is not the same thing but they do have some connection between each other. Sex comes down to our biological char acteristics; it's the genitals that we are born with that distinguish from female and male. Gender on the other hand, Is our behavioral characteristics that involve feelings and attitudes (Furze 2012).Not everyone Is the same, no matter what sex your born some people may feel different inside, this is called interest, it's a condition where a person is born with a or male. Transgender are people who self-identity does not conform definitely to invitational notions of male or female gender. Panderer who are people are those who do not wish to be labeled as female or male in gender, as they feel that they do not fit into binary genders because they feel they are all genders.Homosexuality is a sexual attraction to (or sexual relations with) persons of the same sex (Lower,J 2012). There are four theories of gender; Functionalism, Conflict theories, Symbolic interaction theories and the Feminist Theory. Symbolic interaction theory relates to how gender is formed with the connections and interpretations of society. It is analyses with a mirror perception and an examination of gender on a day to day level, for example men will talk over women to demonstrate a higher level of power.Functionalism is really relating to how the society works as a whole. From where men do contributing and active work and where women commit to the expressive roles to society. In this theory theorists saw the big wage gap of inequalities as result, women would commit to families roles rather than working roles. Conflict theories a society where women are severely disadvantaged with the inequalities that have be formed u to social structure.An example of this is a problem that has been happening for decades the wage inequalities between men and women; we see that men have been having earning more than women even if it's the same role in a Job. Lastly, the feminist theory is the theory where women have operated a movement that aims to demonstrate the position of women in society and to highly improve their status in society. Gender inequality can and should be changed for the benefit of all. All these theories can in the end result to gender division of labor.

How consumers are protected in contracts for the sale Essay

Goods are any form of products that are supplied to consumers for their convenience. They are generally modelled as having diminishing marginal utility. Ultimately, whether an object is a good or a bad depends on each individual consumer and therefore, it is important to realize that not all goods are good all the time and not all goods are goods to all people. Sourced: http://en.wikipedia.org/wiki/Good_(economics) Role of the Sales of Goods Act 1979: The Sales of Goods Act 1979 gives consumers the opportunity of returning or exchanging products which do not fit the description for example, if a consumer has joined a new contract with the O2 and have been told that with the new contract they get a contract phone in black, however on the day when the phone arrives its white then the consumer can take their problem straight back to O2 and they would have to change the product straight away as it doesn’t look like what it is said to. Also if the contract clearly states that it will be a particular phone and turns out to be a different make then O2 would have to make sure the exchange the products and supply the customer with the one they have stated. Express Terms of the Sales of Goods Act 1979: An express term of a contract is a declaration which is made by two or more organisations; and has agreed upon what is stated in the contract, the contracts can be made through verbal methods or by word of mouth. Once the contract has been agreed upon both the organisations have to make sure the follow the deal. Conditions: A condition is a term which has to be followed within the agreement, For example, if O2 are selling their phone contract to customers, whereas supply customers with a different phone contract then it shows that  O2 did there bit of providing the customer with a mobile phone contract however didn’t provide them with the right one. A breach of contract will entitle O2 to follow the correct law of the contract and provide the consumer with the right one. Warranties: A warranty is a term that does not fully follow all agreements, so For example, carrying on from the O2 phone contract issue , when the customers buys the phone contract and is assured by the company that they will receive a special tariff with the contract. Therefore, when the phone contract arrives on the day there is no extra tariff, when the party doesn’t stick to its word then this is seen as a warranty. The customer is able to sue the supplier however it doesn’t mean that the agreement will end. Implied terms of the Sales of Goods Act 1979: There are sequence of conditions which are automatically prepared in every contract by the sales of goods act; and they would be dealing with the following which include: title, description, fitness for purpose and satisfactory quality. I have stated these factors below and explained what each and every one of them means: Title: this is when there is an implied condition which allows the sellers to have the right to sell the goods for example, O2 impliedly confirms that the phone contract it sells actually belong to it and also that it can legally pass on the ownership to another telecommunications company, however if O2 are not able to pass on the title to the buyers then it will mean that O2 will be liable for breach for the contract. Description: the contract must fully explain how the product has been described, when there is a contract for the sales of goods by description then there will be an implied condition that the goods will correspond with that description. However the slightest removal from the description will then enable the buyer into rejecting the goods for breach of condition of the contract made. Fitness for purpose: A fitness for purpose is where a seller who in this case  is O2 plans to sell its goods in the good courses of their business, for example if O2 was to sell their contract to the consumers for the business to be better and make more sales. There is an implied condition for this was they are fit for the particular purpose, this means that the buyer (consumer) has expressly or impliedly known to the seller. Satisfactory quality: The satisfactory quality is where the sellers sell goods for the good of their business; there is an implied term that the goods that is supplied are of the right satisfactory quality. However except to the extent of defects which are brought straight to the buyer’s attention, this will be done before the contract is made meaning that T-Mobile will need to sell satisfactory quality to their consumers. Conclusion: Overall in the briefing sheet I have made sure that all evidence is provided, also that a clear explanation is made of how a contract protects the consumer and what happens if that contract is breached. Mainly information is suggested on the different conditions made by the sales of goods act such as title, description, fitness for purpose and also satisfactory quality. Factors that invalidate contracts: There are many factors that can make a contract invalidated, which means that the contracts cannot be used anymore, such as the following: Misrepresentation: Misrepresentation is where there is a false statement in the contract which is made by one of the parties to the other before the contract is agreed on. There is no general duty to disclose facts, and silence will not normally amount to a misrepresentation. But gestures, smiles or a course of conduct may amount to a representation. Duress: Duress is where a party enters into a contract against their will for example, if O2 is forced into a contract by either violence or treat of violence to themselves or to their family then it means that the contract that is being made may become invalid. In this case the affected party can avoid the contract on the ground of duress; this is because all parties who are entering a contract must enter freely. Mistake: In general terms a mistake  is when a contract is being made however one of the party members may have made a mistake in knowing what they are agreeing to or a contract can be made which turns out to be wrong, this i s down to a mistake occurring, sometimes when there is a mistake in a contract it can make it invalidated.

London Networking Solutions Article Example | Topics and Well Written Essays - 3750 words

London Networking Solutions - Article Example (This is a brief introduction to a ghost company, which is not in existence in reality. It's just a creation to answer the question.) MaxiProfit is a management consultancy firm. Management consulting simply refers to both the industry, and the practice of, helping organizations to basically improve their performance, primarily through the analysis of existing business problems and development of plans for improvement. Organizations often hire the services of management consultants. This is because the pursuit of expansion is vigorous and extensive. Experts in the business fields are therefore required for a number of reasons, including, for example, to gain external, and presumably more objective advice and recommendations, which may help solve the problem at hand or for long term plans. Another is to gain access to the consultants' specialized expertise, where the hiring of permanent employees is not required. Because of the exposure of consultants and their relationships with numerous organizations, consultancies are also said to be aware of industry 'best practices,' this is as noted by Sam Palmisano of IBM (2007) although the transferability of such practices from one organization to another is the subject of debate. Upon successful negotiation of a deal, Consultancies may also provide organizational change management assistance, development of coaching skills to the lead staff of the Host Company, technology implementation, strategy development, and operational improvement services. Management consultants generally bring their own, wealth of methodology and frameworks to guide the identification of problems, and to serve as the basis for recommendations for more effective or efficient ways of performing business tasks. Planning is basically important, so as to end up with a workable procedure. This will help save on many things especially financial. Small and medium enterprises Companies always enter into acquisitions for the main reason of assuming the market monopoly. Ancient philosophers once noted that it's better to expand to a giant. One Socrates further created a light moment that one needs not worry of growing slowly but rather should worry of standing still. Growth by acquisition is a thoroughly tried and trusted strategy. This system allows one to move into new markets or increase their existing market share at much more rapid rate than would be likely through the commonly used organic expansion. This is as discovered by Anita Roddick of Beware management consultants (the learned man 2007). Companies hit the mergers acquisitions trail for a host of reasons. Among those noted also include: 1. Taking the threats of main competitors out of the market. For London Networking Solutions the main competitors are all the IT firms that perform network installations within and without the great UK. IBM and SAGEM, being some of them. 2. Another reason could be to Scale up in a particular sector. These sectors include servicing of the installed networks, offering of spare parts and consultancy as far as IT is concerned. These are the main interests of London Networks.

Law for Business BREF 1 Essay Example | Topics and Well Written Essays - 1000 words

Law for Business BREF 1 - Essay Example This is because at the time of the sale, the toys were not yet in a deliverable state and Megastores’ duty to prepare it for delivery was not yet discharged. The conclusion is that Megastores should shoulder the responsibility for the damage to the two toys whilst Toys4U should be free from such responsibility. The parties involved here are Megastores and Toys4U, the seller and the buyer, respectively. The subject of the contract of sale is a Polaris missile toy, ten units of them. Megastores contended that Toys4U was liable for the damage of two of the toys because ownership had already passed to the latter at the time the damage occurred. The issue here is whether or not ownership had already passed to Toys4U at the time of the damage. Toys4U is not liable for the damage of the two Polaris missiles toys because it occurred before ownership passed from Megastores to Toys4U. This is supported by the provisions of the Sale of Goods Act 1979 (SoGA) and pertinent case law previously decided by the courts. The applicable statute here is the Sale of Goods Act 1979 (SoGA hereafter), which received Royal Assent on December 6, 1979 and took effect commencing January 1, 1980. The SoGA governs transactions of sale of goods within the jurisdiction of the United Kingdom. Specific provisions of said law applicable here are: s 2(1), which defines a contract of sale; s 17 (1) and (2), which provide for the exact time specific or ascertained goods are deemed transferred from seller to buyer; s 18 Rule 2, which provides for the exact time property passes from seller to buyer when seller is first required to put goods in a deliverable state, and; s 20 (1), which allocates risk liability to parties. Section 20 (1) of the SoGA 1979 provides that the property subject of the sale remains at the risk of the seller until transferred to the buyer. This means that Megastores should shoulder damage sustained by the toys unless ownership was explicitly or implicitly

The Future of Healthcare Information Systems Coursework

The Future of Healthcare Information Systems - Coursework Example Some of the required skills include the web and computer technology. Additionally, they need the managerial and organizational leadership and competencies needed for the changes in the operational roles and methods. It had become important to comprehend the functional capabilities of technologies that are associated with e-health, health records, and also telecare (Bashshur, 2013). In standardization the automation process and services will not be feasible in the absence of data standards that enables communication through the internet oriented programs and languages. Some of the core limitation in setting up the standards concern the substandard definition of deliverables. The health sector will fail in determining the objective and the functionalities that are desired for the health application and their conflicts to define the minimum sets of data for clinical and operational management of e-health. The implementations and standard development is a slow process and tends to need a lot of regulatory actions (Bashshur,

Managing Organisational Change Essay Example | Topics and Well Written Essays - 500 words - 1

Managing Organisational Change - Essay Example ge in the organization that there are change management models and dynamics of change theories to serve as guides in the cases of change in the organization. The major cause of the problem in the case study is approach. The approach with which the industrial engineer went about his change is to blame for the problems that were encountered. This argument is made against two of eight dynamics of change lessons suggested by Fullan (1993) and quoted in North Central Regional Educational Laboratory. According to Fullan (1993), â€Å"You cant mandate what matters. The more complex the change, the less you can force it.† In fact, the change desired by the engineer was a very major change that should have gone through a series of step-by-step processes in implementing. The engineer seemed to be in a hurry to make the change and perhaps his glory shine. He was therefore eager to force the change (forgoing how his team leader felt about it). The second point raised by Fullan (1993), which is closely related to the first is that â€Å"individualism and collectivism must have equal power. There are no one-sided solutions to isolation and gro up think.† For this reason, the engineer should have worked more on convincing all stakeholders in the department to fully understand him before implementing the change and in implementing the change he should have factored in the views and ideas of each and every stakeholder to the latter. Looking at the kind of change that the industrial engineer wanted to undertake, it is the kind that can be described as individual change. For this reason, ADKAR model for individual change developed by Prosci is recommended for future changes of that nature. â€Å"Proscis model of individual change is called ADKAR - an acronym for Awareness, Desire, Knowledge, Ability and Reinforcement† (Prosci, 2010). From the ADKAR model, the industrial engineer should have sensitized an Awareness of the need for change among all stakeholders in the team, sort the
