Modern democracy develop in America Essay Example for Free
Modern democracy develop in America Essay The English colonies on the eastern coast of American can be divided into three groups, the North, the Middle Colonies and the South. They all have very different attitudes but they all came here to America to escape from the oppression back in Europe and to develop a new, democratic country. To establish democracy, they all have to face the same enemy, the British. Modern democracy involves the right to vote, check and balance, and an elected representative. The main reasons for development of modern democracy in America were religion, wealth, political freedom, pragmatism and secularism. Religion and political freedom are strongly related to each other because Christianity provided an essential moral foundation for liberal democratic government. The Pilgrims who reached New England in 1620 escaped from religious persecution by the English church and government and the corruptions of Holland. Soon they decided to set up their own government base on Christian ideas, particular the idea of equality. It was one of the early steps towards modern democracy in America. The Pilgrims drew up an important agreement called the Mayflower Compact. The agreement stated that the government would make just laws and equal with the consent of the colonists. In practice this meant that adult male Pilgrims met from time to time to elect a governor and a small group to assist him. The Puritans also hated the hierarchy system in the English church. But comparing to the Pilgrims, the Puritans were more ambitious. They thought it was destiny and Gods will that brought them to America. Religion and the idea of city upon the hill caused them to form a democratic government. City upon a hill was proposed by John Winthrop. He meant that the new colony would be an example for the rest of the world of how God meant men and women to live. The Puritans should build their city well and it would become a model which England might follow. Wealth also hindered the movement of democracy. First of all, the colonists in the south went to American hoping to find wealth and success which they found by growing tobacco and slave trade. Once they got wealth, they wanted to protect their property and to gain further profit. The only way to doà this is to have a government system where it will concern about peoples self interest. As a result, a democratic government is developed where most issues were approved or discussed by the people before it was passed. Pragmatism means human taking practical actions to problems. America is a new, strange land to the colonists. The colonists had to be very flexible to cope with the wilderness. Secularism means the exclusion of religious and supernatural beliefs. These two ideas combined to develop another characteristic of modern democracy that is religious freedom. It was first suggested by William Penn, a Quaker. They believed all men are equal no matter what race or what religion they believed in. The Quakers thought religion does not dictate political decisions, though the moral views originating in Christianity remain. Rather then concentrating on the religious aspect, they concentrate on improving their lives in this new country. The Shakers held a similar idea with the Quakers. They believed in Hands to work, heart to God. This developed the idea of you can believe in any religion or none at all, with little legal or social sanction, that is the freedom of religion. The main cause of the American War of Independence is how the British treated Americans after the Seven Years War. The Seven Years War (1756-1763) had the French on one side and Prussia backed by British gold on the other. The Seven Years War was mainly the result of trading rights. The British colonials (Americans) were pinned up against the Atlantic seaboard, with only the Hudson Bay Company in the north challenging the French trading. The colonists were running out of land. British found the need to expand. But doing so, they would enter the Ohio Valley, controlled by France. In the end, France was defeated. Although Britain won the war, they found themselves in an unfavourable situation. The war was longer than the British had expected and was expensive. Even worse, the colonists were moving west. In order to maintain their new land in America British must send troops to protect it, this was another huge spending. Since Britain had defended the thirteen colonies, they thought tha t the colonists should pay for the troops by various taxes. Starting from 1763, Britain tried to apply its own policy onto the American colonists. The American colonists were unpleased because the reason why there were here in America was to escape from English rule but now the British government was making decisions, disregarding the assemblies that they established earlier. A few events highlighted the colonists resentments and anger toward Britain. In 1764, the Revenue Act was introduced. It stated that colonists have to pay duty for molasses which is used to make rum. It was the first time that the colonists felt the unjust of British rule. The next year, British introduced another tax through Stamp Act. This Act made colonists to buy stamps for newspaper and many other essential items. They even have to buy license for playing cards and dice. The colonists became outrageous, they believed only their assemblies can tax on them, not the London Parliament which is few thousands miles away and they had not much power in it. The anger towards British rule was intense by Britain demolishing all duties in the Townshend Act apart from tea. The colonists regarded this as a bribe to make them end the boycott with British government so that the British can tax them. As a result, a first actual rebellion was broke out and it was known as the Boston Tea Party. Few colonists disguised themselves as Indians and threw cargos of tea into the harbour. This rebellion alerted the British. The British decided to make a harsher plan towards America. The Intolerable Acts were made in 1774 to gain total control over American colonists. The British block ports and only allow American assemblies to meet once a year. This is the ultimate reason for making the American wanted to go to war with Britain. The Acts caused the colonists to stop all trade with Britain and raise their own troops. Americans felt that Britain was taking their democracy away by simply ruling them in British way. Under British rule, Americans did not have the right to vote or to elect government. They did not have religion freedom and must follow the English church. They could not have their own trade. The colonists feelings could be expressed through the Philosophes arguments. As the famous philosophe, Voltaire said, I disagree with everything you say, but will defend to the death your right to say it!, he believed that the Church stood in the way of truth by telling people what to believe instead of allowing them to think for themselves. The American extended thisà idea even further and thought that Britain was in the way of their democracy and that the welfare of the colony and the Empire were not always synonymous. The philosophes also emphasised on human rights and this related to how the American thought when a government does not consent the governed, it should be change. The colonists fled from the oppression back in Europe and wanted to start a new life. Their religion, ambition and attidtues finally led them to the road to modern democracy. But Britain disregarded their rights and democracy and this is the immediate cause of the American War of Independence.

Benefits of Adult Foster Care (AFC)
Benefits of Adult Foster Care (AFC) Types of Community-Based Long Term Care Services Crystal Mullen What did you learn this week that you did not know before or that you found interesting? What outside resources did you use this week? Your submission should be 1 page APA formatted paper, not including your title page. Although I was blessed to grow up in a home with a mom who loved me and provided for all my needs, I knew not all children were as blessed. I remember watching television shows like ââ¬Å"MacGyverâ⬠and talk shows like ââ¬Å"Donahueâ⬠and ââ¬Å"Oprahâ⬠that spoke about foster children who grew up in various homes until their 18th birthday. Then, almost without warning they are dropped out of the foster care system because they are now legally considered an ââ¬Å"adultâ⬠. I always thought that once a person turns 18 there is basically no long term assistance for individuals who are unable to care for themselves and I always found that premise to be so cruel because there are adults who need to be cared for. Well, Iââ¬â¢m happy to report that for those who need it the most, there is such a thing as Adult Foster Care (AFC). AFC offers physically or mentally impaired, frail senior citizens or simply ailing adults around the clock assistance that they may not receive from their own family members or caregivers. Often these caregivers are overwhelmed and find themselves unable to continue the necessary care for their loved one. In these cases the only alternative would be to admit them into the AFC system (Boehlke, 2013). Many times AFC homes are large homes that are set up to mimic a traditional, mainstream home that could teach these adults life-skills that will help them interact with society the best of their own ability (Boehlke, 2013). AFC is no substitute for a therapeutic residential facility where an adult would receive services like awake night or nursing care support (Fosterparenting.com, 2013). However, the home does provides 24 hour assistance for up to five adults for those who are simply unable to care for themselves. Adults receive their meals, are supported, supervised, and even receive as sistance with their personal care needs while obtaining necessary training in living skills. Licensed providers are paid by the state that has the home, usually on a monthly basis (Fosterparenting.com, 2013). Reviewing the facts with the various types of AFC homes as well as the duration of stay will help a family member or caregiver determine an informed alternative on where he or she can send their loved one to be cared for long term (Boehlke, 2013). If a person were to develop an AFC home, he or she would require vision, a competent staff, a budget, and the capability of meeting all applicable policies and procedures, regulations and laws. These items can be realized by taking the following steps: 1 A person who is interested in developing an AFC home should research the applicable state laws and regulations where the home is to be founded. States govern AFC through their Bureau of Children and Adult Licensing, Social Services Department, Department of Health, or the stateââ¬â¢s Department of Human Services. This is because when an AFC home is being set up, the applicable state office that oversees AFC homes needs be identified. The rules and regulations for creating and establishing an AFC home in each state can be found through Internet research (Rappeport, 2013). 2 Interview people who already manage foster homes. AFC homes may be found through the state office that provides licenses for AFC homes. That are quite a few questions that may arise would be appropriate to discuss when planning to create an AFC. One question to consider would be what type of population does this particular home serve? For example, are they mostly developmentally challenged individuals, emotionally challenged individuals or a mixture of both? Another set of questions to consider would be what is the general age range this AFC home serves? If there is a diversity of ages in the home, how do individuals interact with each other despite the age differences? Finally though certainly not exhaustively I would consider asking the question what does the AFC home schedule look like. For example, does the schedule enable those who can to work outside the home? If so, how are residents able to obtain work (Rappeport, 2013)? Answers to questions like these and many others could prepare an individual for opening an AFC home. 3 Contact the state as well as federal government office that offers grants for the establishment of AFC homes. Periodically, the Department of Health and Human Services (HHS) provides grants and/or loans for the development of AFC homes. As soon as the home has been approved the appropriate government entities will then allocate the proper compensation that will be allocated toward the eligible AFC individuals to manage the home and care for their residents in a licensed AFC facility (Rappeport, 2013). 4 Licensed assistants and staff need to be recruited and implemented to help maintain the facility. What the home will need to run efficiently will be based on the needs of the residents they house. This includes the severity of their disabilities and the number of residents who live in the home. The stateââ¬â¢s regulatory office that governs AFC homes will make available a list of the requirements that state holds for the staff in that home. Information for these requirements can be retrieved from the offices website. Generally, most states require that those desiring a job in a foster care home complete a basic course in AFC followed by continued education hours annually. A criminal background check may also be required (Rappeport, 2013). Conclusion I can now see how AFC can benefit more than the adults who live there. First of all, adults who are unable to take care of themselves have a place to go where they can both receive care while also be enabled to live as independently and autonomously as possible. Furthermore, family members and caregivers who become overwhelmed with the responsibility of caring for these adults have an option of ensuring care for their loved one while restoring a sense of normalcy within their own home. Finally, though not exhaustively, I can see how AFC can be a viable business option where licensed personnel can be compensated for caring for those who cannot care for themselves. I donââ¬â¢t know if they are adequately paid for their services, but I still see it as a selfless occupation. Therefore, AFCs give hope to adults to live a fulfilling life without being tossed out by the traditional system. They benefit adults, their families, and those who manage the AFC home.

Wireless Charging Of Mobile Phones
Wireless Charging Of Mobile Phones Abstract -With mobile phones becoming a basic part of life, the recharging of mobile phone batteries has always been a problem. The mobile phones vary in their talk time and battery standby according to their manufacturer and batteries. All these phones irrespective of their manufacturer and batteries have to be put to recharge after the battery has drained out. The main objective of their manufacturer and battery make. In this paper a new proposal has been made so as to make the recharging of the mobile phones is done automatically as you talk in your mobile phone! This is done by use of microwaves. The microwave signal is transmitted from the transmitter along with the message signal using special kind of antennas called slotted wave guide antenna at a frequency of 2.45GHz. There are minimal additions, which have to be made in the mobile handsets, which are the addition of a sensor, a rectenna and a filter. With the above setup, the need for separate chargers for mobile phones is e liminated and makes charging universal. Thus the more you talk, the more is your mobile phone charged! With this proposal the manufacturers would be able to remove the talk time and battery standby from their phone specifications! INTRODUCTION THE ELECTROMAGNETIC SPECTRUM To start with, to know what a spectrum is: when white light is shone through a prism it is separated out into all the colours of the rainbow; this is the visible spectrum. So white light is a mixture of all colours. Black is NOT a colour; it is what you get when all the light is taken away. Some physicists pretend that light consists of tiny particles which they call photons. They travel at the speed of light (what a surprise). The speed of light is about 300,000,000 meters per second. When they hit something they might bounce off, go right through or get absorbed. What happens depends a bit on how much energy they have. If they bounce off something and then go into your eye you will see the thing they have bounced off. Some things like glass and Perspex will let them go through; these materials are transparent. Black objects absorb the photons so you should not be able to see black things: you will have to think about this one. These poor old physicists get a little bit confused when they try to explain why some photons go through a leaf, some are reflected, and some are absorbed. They say that it is because they have different amounts of energy. Other physicists pretend that light is made of waves. These physicists measure the length of the waves and this helps them to explain what happens when light hits leaves. The light with the longest wavelength (red) is absorbed by the green stuff (chlorophyll) in the leaves. So is the light with the shortest wavelength (blue). In between these two colours there is green light, this is allowed to pass right through or is reflected. (Indigo and violet have shorter wavelengths than blue light.) Well it is easy to explain some of the properties of light by pretending that it is made of tiny particles called photons and it is easy to explain other properties of light by pretending that it is some kind of wave. The visible spectrum is just one small part of the electromagnetic spectrum. These electromagnetic waves are made up of two parts. The first part is an electric field. The second part is a magnetic field. So that is why they are called electromagnetic waves. The two fields are at right angles to each other. THE MICROWAVE REGION Microwave wavelengths range from approximately one millimeter (the thickness of a pencil lead) to thirty centimeter (about twelve inches). In a microwave oven, the radio waves generated are tuned to frequencies that can be absorbed by the food. The food absorbs the energy and gets warmer. The dish holding the food doesnt absorb a significant amount of energy and stays much cooler. Microwaves are emitted from the Earth, from objects such as cars and planes, and from another because microwave energy can penetrate haze, the atmosphere. These microwaves can be detected to give information, such as the temperature of the object that emitted the microwaves. Microwaves have wavelengths that can be measured in centimeter! The longer microwaves, those closer to a foot in length, are the waves which heat our food in a microwave oven. Microwaves are good for transmitting information from one place to light rain and snow, clouds, and smoke. Shorter microwaves are used in remote sensing. These mi crowaves are used for radar like the Doppler radar used in weather forecasts. Microwaves, used for radar, are just a few inches long. Because microwaves can penetrate haze, light rain and snow, clouds and smoke, these waves are good for viewing the Earth from space Microwave waves are used in the communication industry and in the kitchen as a way to cook foods. Microwave radiation is still associated with energy levels that are usually considered harmless except for people with pace makers. Here we are going to use the S band of the Microwave Spectrum. Microwave frequency bands Designation Frequency range K Band 18 to 26 GHz Ka Band 26 to 40 GHz Q Band 30 to 50 GHz U Band 40 to 60 GHz V Band 46 to 56 GHz W Band 56 to 100 GHz L Band 1 to 2 GHz S Band 2 to 4 GHz C Band 4 to 8 GHz X Band 8 to 12 GHz Ku Band 12 to 18 GHz The frequency selection is another important aspect in transmission. Here we have selected the license free 2.45 GHz ISM band for our purpose. The Industrial, Scientific and Medical (ISM) radio bands were originally reserved internationally for non-commercial use of RF electromagnetic fields for industrial, scientific and medical purposes. The ISM bands are defined by the ITU-T in S5.138 and S5.150 of the Radio Regulations. Individual countries use of the bands designated in these sections may differ due to variations in national radio regulations. In recent years they have also been used for license-free error-tolerant communications applications such as wireless LANs and Bluetooth: 900 MHz band (33.3 cm) ( also GSM communication in India )2.45 GHz band (12.2 cm) IEEE 802.11b wireless Ethernet also operates on the 2.45 GHz band. TRANSMITTER DESIGN The MAGNETRON (A), is a self-contained microwave oscillator that operates differently from the linear-beam tubes, such as the TWT and the klystron. View fig(1) is a simplified drawing of the magnetron. CROSSED-ELECTRON and MAGNETIC fields are used in the magnetron to produce the high-power output required in radar and communications equipment. The magnetron is classed as a diode because it has no grid. A magnetic field located in the space between the plate (anode) and the cathode serves as a grid. The plate of a magnetron does not have the same physical appearance as the plate of an ordinary electron tube. Since conventional inductive-capacitive (LC) networks become impractical at microwave frequencies, the plate is fabricated into a cylindrical copper block containing resonant cavities that serve as tuned circuits. The magnetron base differs considerably from the conventional tube base. The magnetron base is short in length and has large diameter leads that are carefully sealed into the tube and shielded. The cathode and filament are at the centre of the tube and are supported by the filament leads. The filament leads are large and rigid enough to keep the cathode and filament structure fixed in position. The output lead is usually a probe or loop extending into one of the tuned cavities and coupled into a waveguide or c oaxial line. The plate structure, shown in fig(1), is a solid block of copper. The cylindrical holes around its circumference are resonant cavities. A narrow slot runs from each cavity into the central portion of the tube dividing the inner structure into as many segments as there are cavities. Alternate segments are strapped together to put the cavities in parallel with regard to the output. The cavities control the output frequency. The straps are circular, metal bands that are placed across the top of the block at the entrance slots to the cavities. Since the cathode must operate at high power, it must be fairly large and must also be able to withstand high operating temperatures. It must also have good emission characteristics, particularly under return bombardment by the electrons. This is because most of the output power is provided by the large number of electrons that are emitted when high-velocity electrons return to strike the cathode. The cathode is indirectly heated and is constructed of a high-emission material. The open space between the plate and the cathode is called the INTERACTION SPACE. In this space the electric and magnetic fields interact to exert force upon the electrons. Fig (1) The magnetron structure RECEIVER DESIGN The basic addition to the mobile phone is going to be the rectenna. A rectenna is a rectifying antenna, a special type of antenna that is used to directly convert microwave energy into DC electricity. Its elements are usually arranged in a mesh pattern, giving it a distinct appearance from most antenna .A simple rectenna can be constructed from a schottky diode placed between antenna dipoles. The diode rectifies the current induced in the antenna by the microwaves. Rectennae are highly efficient at converting microwave energy to electricity. In laboratory environments, efficiencies above 90% have been observed with regularity. Some experimentation has been done with inverse rectennae, converting electricity into microwave energy, but efficiencies are much loweronly in the area of 1%. With the advent of nanotechnology and MEMS the size of these devices can be brought down to molecular level. It has been theorized that similar devices, scaled down to the proportions used in nanotechnology, could be used to convert light into electricity at much greater efficiencies than what is currently possible with solar cells. This type of device is called an optical rectenna. Theoretically, high efficiencies can be maintained as the device shrinks, but experiments funded by the United States National Renewable Energy Laboratory have so far only obtained roughly 1% efficiency while using infrared light. Another important part of our receiver circuitry is a simple sensor. This is simply used to identify when the mobile phone user is talking. As our main objective is to charge the mobile phone with the transmitted microwave after rectifying it by the rectenna, the sensor plays an important role. The whole setup looks something like this. THE PROCESS OF RECTIFICATION Studies on various microwave power rectifier configurations show that a bridge configuration is better than a single diode one. But the dimensions and the cost of that kind of solution do not meet our objective. This study consists in designing and simulating a single diode power rectifier in hybrid technology with improved sensitivity at low power levels. We achieved good matching between simulation results and measurements thanks to the optimisation of the packaging of the Schottky diode. Microwave energy transmitted from space to earth apparently has the potential to provide environmentally clean electric power on a very large scale. The key to improve transmission efficiency is the rectifying circuit. The aim of this study is to make a low cost power rectifier for low and high power levels at a frequency of 2.45 GHz with good efficiency of rectifying operation. The objective also is to increase the detection sensitivity at low levels of power. Different configurations can be used to convert the electromagnetic wave into DC signal, the study done in showed that the use of a bridge is better than a single diode, but the purpose of this study is to achieve a low cost microwave rectifier with single Schottky diode for low and high power levels that has a good performances. This study is divided on two kind of technologies the first is the hybrid technology and the second is the monolithic one. The goal of this investigation is the development of a hybrid microwave recti fier with single Schottky diode. The first study of this circuit is based on the optimization of the rectifier in order to have a good matching of the input impedance at the desired frequency 2.45GHz. Besides, the aim of the second study is the increasing of the detection sensitivity at low levels of power. SENSOR CIRCUITRY The sensor circuitry is a simple circuit, which detects if the mobile phone receives any message signal. This is required, as the phone has to be charged as long as the user is talking. Thus a simple F to V converter would serve our purpose. In India the operating frequency of the mobile phone operators is generally 900MHz or 1800MHz for the GSM system for mobile communication. Thus the usage of simple F to V converters would act as switches to trigger the rectenna circuit to on. A simple yet powerful F to V converter is LM2907. Using LM2907 would greatly serve our purpose. It acts as a switch for triggering the rectenna circuitry. The general block diagram for the LM2907 is given below. Thus on the reception of the signal the sensor circuitry directs the rectenna circuit to ON and the mobile phone begins to charge using the microwave power. CONCLUSION Thus this paper successfully demonstrates a novel method of using the power of the microwave to charge the mobile phones without the use of wired chargers. Thus this method provides great advantage to the mobile phone users to carry their phones anywhere even if the place is devoid of facilities for charging. A novel use of the rectenna and a sensor in a mobile phone could provide a new dimension in the revelation of mobile phone.

A Comparative Analysis of the Lvov-Warsaw School and Frege-Russells Tradition :: Lvov-Warsaw School Frege Russell Tradition
A Comparative Analysis of the Lvov-Warsaw School and Frege-Russell's Tradition ABSTRACT: The aim of this paper is a comparative analysis of the Lvov-Warsaw School and Frege-Russell's tradition. The Comparison of these is made on the grounds of the analysis of existence. Choosing "existence" as the object of the analysis is very essential. It is so because understanding of the category of existence is strongly connected with the whole system. Thus, while analyzing the category, one can make a reconstruction of the concept scheme (in both traditions); show their functioning; and compare them to each other. It is easy to notice that in both these systems: a) analyzing is strongly connected with the way of expressing existence in a language, b) the essential problem is to which category existence belongs, c) the main question is whether existence is a predicate. Since the problem of analyzingââ¬âespecially the problem of applying logic in philosophyââ¬âplayed an essential role both in Frege-Russell's system and Twardowski's school, the author of this paper wants to show how this was understood there (especially application of logic to some philosophical problems). I. Introductory Remarks G. Frege in the introduction of his "Grundlage der Aritmetik" formulates a general principle: "nach der Bedeutung der Wà ¶rter im Zusammenhang, nicht in iherer Vereinzelung gefragt werden mu" (G. Frege, Grundlage der Arithmetik, Darmstadt 1961, p. XXII, p. 161. H. Sluga, Gottlob Frege, London 1980, p. 94.). This principle is often called a "context principle". It is stated in there that: 1) A term has a meaning when it belongs to a proposition (is one of its elements); 2) Previous analysis of a proposition is a condition for analysis of the term. Such a view presupposes that proposition is something complex and heterogeneous i.e., its elements belong to different semantic categories. The principle given above makes the following distinctions possible: 1) Division of grammatical elements from logical elements, 2) Division of subjective (psychological) elements from objective elements. Quine in his Two Dogmas of Empiricism states that applying this principle makes an important reorien tation in semanticsââ¬â"the reorientation whereby the primary vehicle of meaning came to be seen no longer in the term but in the statement" (W.V.O. Quine, Two Dogmas of Empiricism, in: From a logical point of view, New York 1963, p. 39). From the above it is easy to see that the meaning of a term is connected with its function in the proposition, for as we know the function depends upon it's location in the proposition.

Singapore Essay example -- Politics, Social Control
Can Singapore be described in terms of a Foucauldian ââ¬Ëdisciplinary societyââ¬â¢ or a Deleuzian ââ¬Ëcontrol societyââ¬â¢? Deleuze proposed that we are in the midst of shift from Foucaultââ¬â¢s ââ¬Ësociety of disciplineââ¬â¢ to a ââ¬Ësociety of controlââ¬â¢ (1992: 3). Unlike the ââ¬Ëdisciplinary societyââ¬â¢ where subjects progress from one ââ¬Ëmouldingââ¬â¢ institution to another (schools, college, factories, offices, etc.), a ââ¬Ëcontrol societyââ¬â¢ is typified by constant modulation (Wise, 2002: 32). According to Rose, control operates by affiliating subjects to a variety of practices which by design encourage adherence to certain norms in modern liberal societies (2000: 325). This is what Deleuze meant by a ââ¬Ësociety of controlââ¬â¢. Best believes we need to adopt the Deleuzian concept of a ââ¬Ëcontrol societyââ¬â¢ to explain the societies emerging in the context of the increased surveillance and network capacity perm itted by new ICTs (2010: 9). On the other hand, Hardt and Negri propose this ââ¬Ësociety of controlââ¬â¢ is simply an 'intensification and generalisation of the normalising apparatuses of disciplinarity', that now reaching beyond the institutions that initiated them and into fluctuating networks (2000: 23). Likewise, Munro believes Foucaultââ¬â¢s disciplinary mechanism need updating to bring it in-line with the capacities of modern technologies, not replacing (2000: 693). It is necessary to distinguish between unconscious social control and social control in relation to the institution, the latter being the planned management of a socialised human activity (Lianos, 2003: 415). Institutional control is integral to the specific activities, is usually bureaucratic, and 'is part both of the rationale and the outcome of these activities' (Lianos, 2003: 415). Lianos uses the example of... ... Google offers 'free' storage space, along with other privileges and useful tools, in exchange for personal information that it might use to market targeted goods to its users (Andrejevic, 2007: 296). People submitted their details to Google and Facebook not out of fear or a sense of duty, but so they may enjoy the benefits offered. Although Singaporeans do value their privacy, they are willing to submit that privacy in exchange for financial rewards or convenience (Hui et al., 2007: 27). These authors also report a growing disgruntlement at the increasing amounts of information that websites are demanding. However, it was the quantity of information requested, rather than the sensitivity of the information that had any significant influence on compliance (Hui et al., 2007: 27). This certainly aligns with the ââ¬Ëenticement modelââ¬â¢ proposed by Whitaker (1999: 141).

Affect of Unemployment in Economy Essay
Unemployment (or joblessness) occurs when people are without work and actively seeking work. The unemployment rate is a measure of the prevalence of unemployment and it is calculated as a percentage by dividing the number of unemployed individuals by all individuals currently in the labor force. During periods of recession, an economy usually experiences a relatively high unemployment rate.[2] According to International Labour Organization report, more than 197 million people globally are out of work or 6% of the worldââ¬â¢s workforce were without a job in 2012. There remains considerable theoretical debate regarding the causes, consequences and solutions for unemployment. Classical economics, New classical economics, and the Austrian School of economics argue that market mechanisms are reliable means of resolving unemployment. These theories argue against interventions imposed on the labor market from the outside, such as unionization, bureaucratic work rules, minimum wage laws, taxes, and other regulations that they claim discourage the hiring of workers. How does unemployment affect the economy? Some of the well-known effects of unemployment on the economy are: Unemployment financial costs The government and the nation suffer. In many countries the government has to pay the unemployed some benefits. The greater the number of the unemployed or the longer they are without work the more money the government has to shell out. Therefore, the nation not only has to deal with the lost income and decreased production but also with additional cost. Spending power The spending power of an unemployed person and his/her family decreases drastically and they would rather save than spend their money, which in turn affects the economy adversely. Reduced spending power of the employed Increased taxes and the insecurity about their own work may affect the spending power of the working people as well and they too may start to spend less than before thus affecting the economy and also the society in a negative manner. Recession With the increase rates of unemployment other economy factors are significantly affected, such as: the income per person, health costs, quality of health-care, standard of leaving and poverty. All these affect not just the economy but the entire systems and the society in general. Here are some aspects of the impact of unemployment on our society: The effect of unemployment on our society Unemployment affects not just the person himself but also his/her family and in the long run the society where he lives. Unemployment brings with it despair, unhappiness and anguish. It forces people to live their lives in a way they do not wish to ââ¬â The life expectancy is negatively affected. Life expectancy is the ease by which people living in a time/place are able to satisfy their needs/wants. Here are the main aspects: 1. Mental health: Mental health problems like: Law self-confidence, feeling unworthy, depression and hopelessness. With the lost income and the frustration involved in it, the recently unemployed may develop negative attitudes toward common things in life and may feel that all sense of purpose is lost. Frequent emotions could be ââ¬â low self-esteem, inadequateness and feeling dejected and hopeless. 2. Health diseases: The unemployment overall tension can increase dramatically general health issues of individuals. 3. Tension at home: Quarrels and arguments at home front which may lead to tension and increased numbers of divorces etc. 4. Political issues: Loss of trust in administration and the government which may lead to political instability 5. Tension over taxes rise: Unemployment also brings up discontent and frustration amongst the tax paying citizens. In order to meet the demands of the unemployment fund the government many a times may have to increase the taxes thus giving way to restlessness amongst the tax paying citizens. 6. Insecurity amongst employees: The prevailing unemployment and the plight of the unemployed people and their families may create fear and insecurity even in the currently employed people. 7. Crime and violence: Increase in the rate of crime. 8. Suicide cases: Increase in the rate of suicide attempts and actual suicides as well. 9. Social outing: Unemployment may bring a decrease in social outings and interactions with other people, including friends. 10. Stigma: Unemployment brings with more than just ââ¬Ëno workââ¬â¢. It also brings with it the disgrace that the person has to bear. Nobody likes to be termed as unemployed. 11. Standard of leaving: In times of unemployment the competition for jobs and the negotiation power of the individual decreases and thus also the living standard of people with the salaries packages and income reduced. 12. Employment gaps: To further complicate the situation the longer the individual is out of job the more difficult it becomes to find one. Employers find employment gasps as a negative aspect. No one wants to hire a person who has been out of work for some time even when thereââ¬â¢s no fault of the individual per say. 13. Lose of skillsââ¬â¢ usage: The unemployed is not able to put his/her skills to use. And in a situation where it goes on for too long the person may have to lose some of his/her skills Benefits The primary benefit of unemployment is that people are available for hire, without being headhunted away from their existing employers. This permits new and old businesses to take on staff. Unemployment is argued[citation needed] to be ââ¬Å"beneficialâ⬠to the people who are not unemployed in the sense that it averts inflation, which itself has damaging effects, by providing (in Marxian terms) a reserve army of labour, that keeps wages in check. However the direct connection between full local employment and local inflation has been disputed by some due to the recent increase in international trade that supplies low-priced goods even while local employment rates rise to full employment. Full employment cannot be achieved because workers would shirk if they were not threatened with the possibility of unemployment. The curve for the no-shirking condition (labeled NSC) goes to infinity at full employment as a result. The inflation-fighting benefits to the entire economy arising from a presumed optimum level of unemployment has been studied extensively. The Shapiro-Stiglitz model suggests that wages are not bid down sufficiently to ever reach 0% unemployment. This occurs because employers know that when wages decrease, workers will shirk and expend less effort. Employers avoid shirking by preventing wages from decreasing so low that workers give up and become unproductive. These higher wages perpetuate unemployment while the threat of unemployment reduces shirking. Before current levels of world trade were developed, unemployment was demonstrated to reduce inflation, following the Phillips curve, or to decelerate inflation, following the NAIRU/natural rate of unemployment theory, since it is relatively easy to seek a new job without losing oneââ¬â¢s current one. And when more jobs are available for fewer workers (lower unemployment), it may allow workers to find the jobs that better fit their tastes, talents, and needs. As in the Marxian theory of unemployment, special interests may also benefit: some employers may expect that employees with no fear of losing their jobs will not work as hard, or will demand increased wages and benefit. According to this theory, unemployment may promote general labour productivity and profitability by increasing employersââ¬â¢ rationale for their monopsony-like power (and profits). Optimal unemployment has also been defended as an environmental tool to brake the constantly accelerated growth of the GDP to maintain levels sustainable in the context of resource constraints and environmental impacts. However the tool of denying jobs to willing workers seems a blunt instrument for conserving resources and the environment ââ¬â it reduces the consumption of the unemployed across the board, and only in the short term. Full employment of the unemployed workforce, all focused toward the goal of developing more environmentally efficient methods for production and consumption might provide a more significant and lasting cumulative environmental benefit and reduced resource consumption . If so the future economy and workforce would benefit from the resultant structural increases in the sustainable level of GDP growth. Some critics of the ââ¬Å"culture of workâ⬠such as anarchist Bob Black see employment as overemphasized culturally in modern countries. Such critics often propose quitting jobs when possible, working less, reassessing the cost of living to this end, creation of jobs which are ââ¬Å"funâ⬠as opposed to ââ¬Å"work,â⬠and creating cultural norms where work is seen as unhealthy.

Market Segmentation
Division of marketing for Kit Kat ââ¬â chocolate bar, into geographic , demographic, psychographic and behavioural segmentation. Geographic segmentation The market is broadly divided into Urban (cities and towns) and Rural (villages). Kit Kat caters the high urban need by making products available that too with a variety with the help of which the rural crowd can be kept attracted. Rural needs are also kept in mind and there is nothing even required for Kit Kat to make an effort to attract rural crowd because of the price.Kit Katââ¬â¢s price is very reasonable that attracts rural crowd and gives them proper quantity of chocolate as well be it the two-finger Kit Kat or the four-finger. Since Kit Kat has its price stable and has a very minor change in its price, it can still target the rural crowd by making them aware that compared to their competitors Cadbury their product is cheaper and much affordable. Demographic segmentation With the youth population getting larger, Kit Kat looks to take an advantage of that.They have also segmented the market for children, adults and aged people. Kit Kat is a type of a chocolate that is light and can be consumed by every age group. Majority of the customer base in market comprises of middle class and upper middle class. But income groups have never been a concern for Kit Kat, the prices of Kit Kat have been stable for decades and the prices are such that any income group can afford it. Psychographic segmentation Market Segmentation Market segmentation Market consists of large number of actual and potential customers. The process of splitting the market into different groups or segments based on the needs, characteristics or buyer behavior is called as Segmentation (Kotler, Brown, Adam, and Armstrong, 2007). Singapore Airlines (SIA) has used traditional approach adopted by legacy carriers for segmentation. SIA focuses on business travelers and the price sensitive leisure travelers. The business paradigm of SIA has clearly differentiated these two segments by catering to their heterogonous need. In order to penetrate their existing market and expand their revenue base they are also focusing on additional segment based on consumer loyalty. The increasing revenue of SIA has been depicted in appendix 1. Detailed analysis of segmentation strategy used by Singapore Airline is given as below: Psychographic variables Preferences: The two major groups of business and leisure travelers differ in their preferences. Itââ¬â¢s believed that on an average in aviation industry elite travelers contribute up to 50% of revenue though they add up to less than 20% in passenger number (Brancatelli, 2009). Hence the preference of this particular segment (Business travelers) is given additional importance. They are given exclusive in-flight service with respect to variety of cuisines being served, exotic drinks and special seating comfort (Wirtz and Johnston, 2003). At the same time since the other segment i. e. the leisure travelers form the major chunk of passengers their preferences also cannot be ignored. They too are given in-flight services which can be termed best as per industry practices. Nature of demand: Since the nature of demand varies with respect to business and leisure travelers it is used as a parameter for discriminator analysis. Business travelers demand more working space, internet and telephone connections whereas leisure travelers demand more in-flight entertainment features (Singapore Airlines, 2009) Behavioral variables: Brand loyalty: Customer loyalty can also be used as a basis for market segmentation (Kotler et al, 2007). SIA has also segmented their market on the basis of customer loyalty. Retaining an existing customer goes a long way in bringing in additional revenues for the company and this is exactly the reason why SIA has chosen loyalty as a variable for segmentation. SIA gives KrisFlyer and PPS club membership to their loyal customers in a bid to retain their loyalty. KrisFlyer silver group members, enjoy certain privileges such as they are allowed to fly on short notice even if the reservation is not confirmed. Similarly PPS club members are given privileges like free accident and travel insurance, increased baggage allowance etc. Singapore Airlines, 2009) Targeting Target marketing basically refers to the division of the market into various different segments and then focusing on prominent and significant key segments (Kotler et al, 2007). SIA targets customers based on lifestyle, income group and social class. Lifestyle SIA targets segments based on lifestyle (Murali and Murali, 2008). SIA ensures that customers, who give more importance to comfort and luxury , have a great experience on board. SIA places special focus on high end and discerning customers and targets customers accordingly. Income Group Income group is also used as a parameter for targeting customers (Murali et al, 2008). SIA is a premium airline which focuses on providing value based flying experience to the customer and it comes with a heavy price tag. Hence, SIA aims to tap the high and middle income groups which are more likely to pay for quality. Social Class SIA also targets customers based on their social class. Every social class has beliefs and attitudes, which shapes their buying behavior (Kotler et al, 2007). People belonging to the elite class will go for a high end brand, so being a luxury airline SIA targets the high social classes. Positioning Positioning can be defined as the process of framing the image of a company in the view of the target market, based on the products and services offered (Kotler et al, 2007). SIA positions itself as a premium luxury carrier. SIA portrays itself as an airline that provides all the luxuries that one may desire while travelling, be it comforts, a hospitable crew or an overwhelming in-flight experience. The primary message used by SIA, is self explanatory; A Great Way to Fly (Singapore Airlines, 2009). The marketing strategy has been consistent all the way, the message that SIA wants to send across to the target market is that; it is the best airline in its segment. SIA joined the Star Alliance in 2000, which is the first and the largest airline alliance of its kind (Singapore Airlines, 2009). The ââ¬Å"Singapore Girlâ⬠strategy was a very influential idea that gave SIA the push it needed and went on to become a very successful brand icon (Roll, 2009). This brand personality of ââ¬Å"Singapore Girlâ⬠further helps them reaffirm their position as an airline which provides high level of hospitality. Brand positioning for SIA is depicted in the diagram shown below. The strategy adapted by SIA is to position themselves as a high quality and high value brand and especially with the ââ¬Å"Singapore Girlâ⬠concept they show the level of hospitality offered to the customers. SIA positions itself away from the competitors in every class, be it economy class, business class or first class. In the above diagram; AIQ ââ¬â AirAsia ALK ââ¬â Srilankan Airlines DLH ââ¬â Lufthansa SIA ââ¬â Singapore Airlines In the current scenario, where premium airlines are cutting down onboard services to reduce prices in order to compete with the low-cost carriers, SIA continues to maintain their brand image. The management of SIA believes that there are customers willing to spend a good amount for quality products and services (Roll, 2009). So looking for high end customers is not an issue, rather their job is to position the brand in such a way that customers get attracted to fly on SIA, and so far SIA has been able to create, what they refer to as the Wow Effect (Wirtz et al, 2003).
