What You Need to Know About the Weak Force

What You Need to Know About the Weak Force The weak nuclear force is one of the four fundamental forces of physics through which particles interact with each other, together with the strong force, gravity, and electromagnetism. Compared to both electromagnetism and the strong nuclear force, the weak nuclear force has a much weaker intensity, which is why it has the name weak nuclear force. The theory of the weak force was first proposed by Enrico Fermi in 1933 and was known at that time as Fermis interaction. The weak force is mediated by two types of gauge bosons: the Z boson and W boson. Weak Nuclear Force Examples The weak interaction plays a key role in radioactive decay, the violation of both parity symmetry and  CP symmetry, and changing the flavor of quarks (as in beta decay). The theory that describes the weak force is called quantum flavourdynamics (QFD), which is analogous to quantum chromodynamics (QCD) for the strong force and quantum electrodynamics (QFD) for the electromagnetic force. Electro-weak theory (EWT) is the more popular model of the nuclear force. Also Known As:  The weak nuclear force is also referred to as: the weak force, the weak nuclear interaction, and the weak interaction. Properties of the Weak Interaction The weak force is different from the other forces: It is the only force that violates  parity-symmetry (P).It is the only force that violates charge-parity symmetry (CP).It is the only interaction that can change one kind of quark into another or its flavor.The weak force is propagated by carrier particles that have significant masses (about 90  GeV/c). The key quantum number for particles in the weak interaction is a physical property known as the weak isospin, which is equivalent to the role that electric spin plays in the electromagnetic force and color charge in the strong force. This is a conserved quantity, meaning that any weak interaction will have a total isospin sum at the end of the interaction as it had at the beginning of the interaction. The following particles have a weak isospin of 1/2: electron neutrinomuon neutrinotau neutrinoup quarkcharm quarktop quark The following particles have a weak isospin of -1/2: electronmuontaudown quarkstrange quarkbottom quark The Z boson and W boson are both much more massive than the other gauge bosons that mediate the other forces (the photon for electromagnetism and the gluon for the strong nuclear force). The particles are so massive that they decay very quickly in most circumstances. The weak force has been unified together with the electromagnetic force as a single fundamental electroweak force, which manifests at high energy (such as those found within particle accelerators). This unification work received the 1979 Nobel Prize in Physics, and further work on proving that the mathematical foundations of the electroweak force were renormalizable received the 1999 Nobel Prize in Physics.

Policy analysis - Assignment Example For instance, calculation of the costs and benefits that are valued in executing a water project today is bound to change in the coming years. Consumer price index is the absolute measure of price levels of consumer products whose calculation is based on the product type, region, and buying power of consumers. The price index is usually a fixed value that is set by a regulatory body, for instance, the department of labor in US. The value is based on a fixed weight price of goods that consumers purchase in every month (Adler & Posner, 2006). However, inflation is the measure of the increase in price levels in the economy in average terms. Its value is dependent on market forces since most economies operate under a free market system where forces of demand and supply play a crucial role. Therefore, the main reason why CPI overstates the value of inflation is because CPIs determination is done by an authorized body while inflation rate is determined by the market forces. The CPI figure is based on predictable parameters, and it is fixed for a period while inflationary changes are unpredictable. Indeed, economic value of life is dependent greatly on how one maximizes on the potential loss within the earning system. The value of lost earnings affects individual’s capacity for meeting certain life objectives due to eminent constraints. As noted by various economists, lost time, leads to lost earnings that in turn expose one to diminishing life value. Therefore, the assertion that economic value of life should be based on the present value of lost earnings instead of current earnings is real. Statistical reports from various empirical studies also affirm the fact that lost earnings exposes individuals to serious risks. Lost time has immense negative economic connotations that can be mitigated through effective measures. Willingness-to-pay measures that are based on

Super Size Me Essay Essay Example for Free

Super Size Me Essay Essay SuperSize Me shows that the food industry is to blame for the obesity epidemic in America. Do you agree? –Agree. Throughout the film, SuperSize Me shows that the food industry is to blame for the obesity epidemic in America. After watching the film, one would evidently come to terms with the fact that these industries are to blame. Spurlock presents information, outlining that these companies are only out to get your dollar, regardless of how they achieve their profits. As they continue to grow, these fast food industries find new ways to mass produce their food, quickly and cheaply. This in turn, sacrifices the quality of the food, as SuperSize Me emphasizes the cheap and health threatening ingredients they inject into their food though cartoons and other visual aids to help illustrate. Advertising also plays a major role in the companies’ scheme to inculcate their messages in your thinking, so you buy their product the next time you pass their stores. The film also goes on to highlight that the convenience of these stores along with the addictive elements appended to them, will only have a short term effect on the consumer, stating if these â€Å"trends† continue for the average obese American, the average obese American may not be around for much longer. As one of the highlights of the film, SuperSize Me continually brings up the danger of fast foods has on our health. Spurlock shows the audience this each time he goes for his regular check up with his recruited army of doctors. Each time he attends, his heath clearly declines from its point of origin when the only dependent variable changing his body, is the food he consumes. Until the end of his diet, his ‘glorified’ poor health is accentuated through the words of his health experts as a result of the food he had been consuming. From a point of view outlining film technique, Spurlock ‘intimidates’ the audience with a disturbing 20 lbs. (9kg) jar full of fat placed on the table. This was a confronting move he played in order to get his audience thinking about the reality of the danger in fast food when it is placed in front of the individual. Even more so, Spurlock consumed 30lbs. of sugar by the end of his diet. Mostly in the coke, the sugar also accounted for about 10% of the meal, that is, the buns, meat and fries. The poor quality of the food also adds to the problem, in one snippet of the film, Spurlock continues about the â€Å"McFrankenstein† elements of meat they compose together to create foods â€Å"not utilised by the home cook. In this case, chicken nuggets were the issue. SuperSize Me also informs the audience of the use of advertising, and its psychological effects it can have on individuals. Fast food giants have learned that inculcating their messages into consumers’ minds; will get them in their stores and purchasing their products more often. They have seen advertising as an investment rather a waste of money as they spend â €Å"1. billion dollars on direct media advertising worldwide in 2001† By repetitively bombarding individuals with their brand or logo essentially brainwashes the way they make calculated decisions, next time meal time comes around. This is known as â€Å"brand imprinting† and the film focuses on how this infiltrates the minds of children in particular, stating each child will see â€Å"at least 10,000 advertisements on fast food alone each year. † Children chanting about the fast food brands at the start of the film is a great example of this; the repetitive chant effectively inundates the mind with constant thought of food. These brands aren’t just a food service; they are a basis of comfort as children conduct in playful games around these brands as if they are a part of their life. Spurlock conducted a small experiment on a handful of children to test this brand imprinting. He showed the kids multiple flash cards, each with an icon or image on it such as Wendy’s, Jesus, etcetera. Each time McDonalds came up, every child was able to identify it. Essentially, the bottom line of brand imprinting is to create a positive experience for the consumer at a young age. By doing so you create a safe haven for the customer experience, and as they become adults free to make their own decisions they are then hooked on the products of the company produces, and continues to purchase them. As the generations progress, this can pose a new problem with obesity having an echo effect on the generations to come. The convenience of these stores also contains contributing factors to the obesity epidemic. SuperSize Me shows fast food companies have made it too easy for consumers to get their hands on their products through the plethora of ways you can get your food. All too many times the audience is shown Spurlock receiving his food through the drive-thru or home delivery, but in some cases he will get it himself generally when McDonalds is just down the stairs from the sky rise he is in. The availability of these restaurants is also quite remarkable, Spurlock states â€Å"McDonalds operates over 30,000 restaurants in more than 100 countries on six continents† not to mention most of them never close up shop. On the other hand, some people seem to think that exercising personal responsibility can be the answer to the obesity casualty. This may be possible; however it is short-sighted thinking to overlook the facts about how these food giants have achieved to get to where they are now and continue to do. If we could exercise personal responsibility, then why didn’t we do so when these companies were at their weakest? They are where they are now because they worked around our will power with subtle plans of attack. SuperSize Me has given clear evidence that these food industries are a problem, and has taken an unfortunate turn to result in the harm of our general wellbeing. We can stop them by demanding change, rather than suing them for our problems we can go to our government and demand guidelines by which these companies has to follow by to serve fresh, healthy food that’s not loaded up with sugar and fat. By eating these foods, â€Å"we are part of the problem, but we are also part of the solution. † Wether chose to take action depicts the quality of life we bestow upon ourselves and future generations. â€Å"I guess the big question is, who do you want to see go first? You? Or them? †

Coopers deerslayer: View Of The Native Americans :: essays research papers fc

Cooper's "Deerslayer": View of the Native Americans James Fenimore Cooper was born on September 15, 1789 in Burlington, New Jersey. He was the son of William and Elizabeth (Fenimore) Cooper, the twelfth of thirteen children (Long, p. 9). Cooper is known as one of the first great American novelists, in many ways because he was the first American writer to gain international followers of his writing. In addition, he was perhaps the first novelist to "demonstrate...that native materials could inspire significant imaginative writing" (p. 13). In addition his writing, specifically The Deerslayer, present a unique view of the Native American's experiences and situation. Many critics, for example, argue that The Deerslayer presents a moral opinion about what occurred in the lives of the American Indians. Marius Bewley has said that the book shows moral values throughout the context of it. He says that from the very beginning, this is symbolically made clear. The plot is a platform for the development of moral themes. The first contact the reader has with people in the book is in the passage in which the two hunters find each other. "The calls were in different tones, evidently proceeding from two men who had lost their way, and were searching in different directions for their path" (Cooper, p. 5). Bewley states that this meeting is symbolic of losing one's way morally, and then attempting to find it again through different paths. Says Bewley, "when the two men emerge from the forest into the little clearing we are face to face with... two opposing moral visions of life which are embodied in these two woodsmen" (cited in Long, p. 121). Critic Donald Davie, however, disagrees. His contention is that the plot is poorly developed. "It does not hang together; has no internal logic; one incident does not rise out of another" (cited in Long, p. 121). But according to Robert Long, Bewley has a better grasp of the meaning and presentation of ideas throughout the book. According to Long, although the plot development may not be "strictly linear," it is still certainly coherent and makes sense. In addition, Long feels that, as Bewley states, the novel is a way in and through which Cooper presents moral ideas about the plight of the Native Americans (p. 121). The story of The Deerslayer is simple. It is novel which tells the events which occur in the travels of a frontiersman. His name is Natty, and he is a young man at only twenty years old. Coming from New York of the eighteenth century, he is unprepared in many ways for what he encounters in the frontier.

Foxconn and Apple

Subject: Apple and Foxconn controversy from the eye of the consumer Over the last couple years, Apple and Foxconn have been partaking in poor business methods thus causing them a great deal of deserved criticism. The consumer, must decide whether or not to continue buying from Apple because the consumer is what causes Apple to continue to make new products which results in the poor conditions at Foxconn. Foxconn and Apple violate many ethical, moral and basic human principles. The SituationOver the past several years, Apple's major hardware and development contributor, Foxconn, has received a great deal of criticism over their working conditions and benefits. There are over a dozen Foxconn factories in China, all of which employ hundreds of thousands of people. To this day Foxconn remains the leader in electronic component manufacturing. Since 2010, various accounts of mistreatment of employees have arose, causing many controversies. The most significant to date, are the many reporte d suicides of Foxconn plant workers.In early June, the most recent suicide occurred of twenty three year old man. It was the first suicide since Foxconn agreed with the United States and Apple to improve working conditions (Foxconn Suicide, 2012). Prior to this suicide, there had been over a dozen suicides in direct correlation to the poor working conditions and low pay. Various news reports and documentaries arose in 2012 exposes this supposedly giant scandal. Apple, one of the worlds most prominent developers of consumer electronics, is making numerous attempts to fix the current issues at Foxconn. The move comes after Apple, criticized over working conditions at its sprawling chain of suppliers in China, agreed to an investigation by the independent Fair Labor Association earlier this year to stem criticism that its products were built in sweatshop-like conditions† (Foxconn Suicide, 2012). The next several years will be dedicated to making Foxconn a positively labeled corpo ration thus giving Apple is good reputation back. The Impact on a Stakeholder Group (Consumer) As a consistent consumer of Apple products over the last decade, one can only be disappointed in the decisions made by Apple.Of course the consumers were not directly involved in the poor conditions of the company or the deaths of many workers. In reality, we the consumers, are indirectly contributing to the current issues at Foxconn. We choose to purchase their products, buy stocks and invest our hard earned money into a company that chooses to do things the easy way rather than the smart way. In a report written by the Insider Staff in 2012 called Apple, Foxconn and China: The Cost of Manufacturing, they said â€Å"Think of your iPhone you would as a hamburger—the meat was once part of a living, breathing animal.Its life was taken so you could have lunch. This is the price for the type of life we lead, whether it's the price we pay to buy something once living that's now a packag e of hamburger or the price for a brand-new iPhone. † The iPhone, Macbooks and iPods we purchase were all at one point a collection of parts. Thanks to the many news reports, we realize that these parts are stained with the blood, sweat and tears of the many workers just trying to make a living. The consumer is the most affected party in this scenario. We choose to purchase Apple's new products for lower prices and faster shipping.We demand Apple to make newer products knowing that we will then buy them. Through these actions taken by the consumers, it allows for all the problems occurring at the Foxconn factories to continue. Apple does deserve come credit for the attempts they have made to fix all of the previously stated issues. â€Å"There is no question that Foxconn has been scrutinized because it produces products for Apple. Also a few years ago there were a number of suicides at Foxconn factories, which prompted labor groups to start looking into working conditions the re.Apple sent a team to China, including a group led by Tim Cook, who is now Apple's CEO. Apple also hired the non-profit Fair Labor Association to audit working conditions at Foxconn. The group has said that Foxconn has made progress at reducing workers' hours and improving conditions, and that Foxconn and Apple do make an effort to let students know they can resign from Foxconn and still graduate, and link the jobs they do at Apple with their studies† (Adams, 2012). The Fair Labor Association conducted a two week examination of the company to make sure it was up to date on all laws and regulations.Foxconn has raised all workers salaries by 16 to 25 percent. They have chosen to hire tens of thousands of more workers so that never again would an individual die from working a thirty hour shift. The FLA conducts interviews of over a hundred thousand employees to make sure they are content and have no serious, life threatening issues with Foxconn (Poeter, 2012). They correct step s have been taken to regain Apple's status as an ethical and beneficial company, while also fixing all of Apple's supplier companies like Foxconn. Ethical Dilemmas There were many ethical dilemmas after the Foxconn Apple scandal was exposed.A CNN documentary team went there and filmed the companies average work day. On January 29th the CNN report appeared which displayed graphic images of the Foxconn factory. â€Å"The segment graphically showed the suicide nets and the factory, it showed workers reportedly as young as 12 who worked shifts as long as 12 to 14 hours a day, six days a week. It also reported on the death of one worker who died at work after a shift of more than 30 hours. There's no question these condition approach the emotional feeling of slavery, if not legal definition.What's missing from the conversation is that Foxconn builds electronics products for a wide variety of companies, not just Apple† (Apple, Foxconn and China, 2012). All of the previously stated conditions violate countless ethical laws. In an article called Business Ethics- Issues written by Jim Riley, he says that a business can not claim to be ethical if the violate ethical practices such as child labor, production is sweatshops, violation of basic rights and ignoring health and safety issues. Foxconn violated absolutely every single one of these practices.The employed children to work and had them working shifts just as long as your average adult would. The physical conditions of the company were terrible, people were hardly allowed to eat, grime and dirt layered the floors and people worked countless hours shoulder to shoulder. Some have even chosen to compare it to Nazi death camps and the blood diamond controversies in Africa. Due to the constant allegations and controversies, Apple has taken giant steps towards creating a bright future. Apple sent in a Chief Operating Officer to the Chinese facility.The team interviewed more than one thousand workers along with crea ting a 24-hour care center (Sherr, 2011). Since 2007 Apple has audited 288 supplier facilities and even continues to do so even if it mean no longer working with them. Apple has found 91 underage workers in these facilities and will break off any ties to those who choose to overlook the issue. Apple is working hard to establish a good reputation for itself. They are pushing their supplier factories to follow every ethical and business guideline so that we the consumer can be happy and comfortable with the products we are purchasing.Analysis of Solution/Actions The 7 Guidelines for Making Ethical Decisions are a perfect example of the rules in which Apple and Foxconn decided to disobey. Firstly, the TV Test states that managers should always ask, â€Å"would they feel comfortable explain this to a TV audience? † Going back to Foxconn and Apple the clear and most obvious answer to this question is NO. Apple and Foxconn hid every negative aspect of the company for over two years . It was not until 2012 where CNN was allowed to go in and film the factory.If the numerous child workers, poor conditions and suicides were exposed earlier, this issue may have been resolved by now. Instead Foxconn covered up the scandal and allowed it to grow and infest throughout the company. Secondly, every child was raised by the Golden Rule, treat others they way you want to be treated. From the managers perspective, they chose to get things done rather than doing them the right way. What this means is that managers did not obey any ethical rules, rather they pushed workers to the extreme so that they could make as many products as possible.In conclusion, Apple's and Foxconn's violations were unacceptable. However, Apple has taken the right approach in correcting all of the issues at Foxconn. Whether or not it works, Apple has done all they can. Now it lies in the hands of the stakeholders to continue to or not to buy the companies products. Cited Work Adams, S. (2012). Apple' s New Foxconn Embarrassment. Forbes. Com, 8.

An analysis of the influence of technology on contemporary interior architecture Essay

The analysis of the articles is based on the influence of technology on interior architecture education and of employer’s expectations in the interior design industry. This also addresses the issues faced by interior designers in today’s world and how technology is hindering/fostering their creativity. Talking about the article on â€Å"Technology Changing the Face of the Modern Fit out†, it addresses a strong point of how the interior design industry was never considered as a crucial part of the industry and was dealt with a stereotype attitude that interior designers dealt only withthe part of â€Å"decorating† the space until technology gained importance. Technology has now given a 180-degree turn to the industry because of which the industry has finally started gaining the deserved recognition. The underlying point in the article â€Å" is technology hindering or fostering the creativity in interior design†, although is on similar lines like the above mentioned article about the positive aspects of technology, it also talks about the pitfall side of technology on the industry. Their argument is supported with an example cited of a professor from a state university of how although he accepts that the technology has given the students, the most innovative platform to communicate their design ideas, somewhere down the lane, the students who are the prospective interior designers are lacking the basic creative skills and hand drafting techniques. â€Å"Interior Designers’ Perceptions of the Influence †¨of Technology on Workplace Performance† article gives us a different perspective of the influence of technology and how it caters to the interior designers. The statement is supported by examples cited by employees from the industry who have been interviewed of how 2D and 3D software have enabled the designers to get their work done in reduced time in comparison to how it was in the past. It also talks about what the expectations of the employers from new hires are, which includes being efficient in 2D and 3D software which will enable them to be proficient in expressing their design ideas. The other side of the coin is that it is hindering the employers in certain ways. This point is well supported by examples they cite of how in case if the computer crashes the students are unable to come up with a hand made drawing ready for a meeting. The over dependence on the computer has led to this state where the new graduates are finding it tough to inculcate sketching and hand drafting although their competent computer skills enable them to complete a design project in no time. The articles that we have looked at firmly state that the influence of technology has its pros and cons. The use of technology has catered to designers in various ways in terms of the time factor, design output etc. But the basic thing we have to understand is every opportunity has both sides. So technology is definitely fostering the designers but having said that it is better that we don’t become over dependent on it that it hinders our creative and innovative skills of designing.

Bolivian Economic Crisis essays

Bolivian Economic Crisis essays Bolivia, as we know it today, is one of the poorest nations of the world, but it is not located in Africa or Indonesia, it is in the middle of South America. Bolivia was, in Colonial times, one of the richest nations in the World. So how can this wealthy nation have fallen so hard in such a short period of time? It might be hard to explain and even harder to understand. Many factors influenced the roller coaster ride that this nation took and some of those factors are still pushing the economy down. However, if we pay more attention to the process of decadence that this nation lived, we may even come to the conclusion that this country was destined to be poor (Bolivian Gov. pg 1). Colonial exploitation, wars, and revolutions were just the beginning of the problems that were followed by adverse atmospheric conditions, geographical disadvantages, and the crumbling of the silver and tin market prices, which led to uncontrollable migration and international debt. Among the possible solutions to restore the nations economy, we find some macro economic reforms that require the capitalization of the state-owned enterprises, the stabilization of the economy by remonitisation, and the international help of entities like the World Bank, the Inter American Bank of Development and US Aid (Bolivian Gov. pg 1). At the beginning of the 17th century, Bolivia was the greatest producer of silver and gold in the world, and the opulence of the country improved Spains economy. According to Norman Galls report (pg 4), it is estimated that 43,000 tons of gold and silver were shipped to Europe by the Spanish conquistadors. In a 1730 census conducted by the Spanish government, the city of Potosi reported an estimated population of 120,000 at a time when London had an estimated population of 200,000. But forced labor and the consumption of food and materials created an extensive trade system that supported operations at Potosi. However, f...

The History and Definition of Solar Cells

The History and Definition of Solar Cells Any device that directly converts the energy in light into electrical energy through the process of photovoltaics is a solar cell. The development of solar cell technology begins with the 1839 research of French physicist Antoine-Cà ©sar Becquerel. Becquerel observed the photovoltaic effect while experimenting with a solid electrode in an electrolyte solution when he saw a voltage develop  when the light fell upon the electrode. Charles Fritts - First Solar Cell According to Encyclopedia Britannica, the first genuine solar cell was built around 1883 by Charles Fritts, who used junctions formed by coating selenium (a ​semiconductor) with an extremely thin layer of gold. Russell Ohl - Silicon Solar Cell Early solar cells, however, had energy conversion efficiencies of under one percent. In 1941, the silicon solar cell was invented by Russell Ohl. Gerald Pearson, Calvin Fuller, and Daryl Chapin - Efficient Solar Cells In 1954, three American researchers, Gerald Pearson, Calvin Fuller, and Daryl Chapin, designed a silicon solar cell capable of a six percent energy conversion efficiency with direct sunlight. The three inventors created an array of several strips of silicon (each about the size of a razor blade), placed them in sunlight, captured the free electrons and turned them into electrical current. They created the first solar panels. Bell Laboratories in New York announced the prototype manufacture of a new solar battery. Bell had funded the research. The first public service trial of the Bell Solar Battery began with a telephone carrier system (Americus, Georgia) on October 4, 1955.

The technology is a port-based access control method that is defined by the Institute of Electrical and Electronics Engineering which can be configured to require mandatory authentication between the network and the client. Communications become impossible without the authentication. Many people consider the 802.1x technology as the foundation of wireless security. However, deploying the 802.1x technology has its challenges. The technology requires devices that are compatible with 802.1x . The technology has weakness in its protocol, as it only authenticates at the establishment of a connection. Further connection does not require authentication, resulting in security risks (Al-Shaer, 2014). Additionally, the technology does not have centralized management capability. As such, the IPsec VPN became introduced. The Virtual Private Networks based on IPsec allow a layer of security to become a part of the wireless network, allowing for the protection of all traffic that flows in and out of the network. The method has several advantages over 802.1x including; Invisibility - Since the technology is based at the network level, it remains invisible in its operations (Snader, 2014). The end users do not have to learn its existence, nor do they have to interact directly with it, which is different from the 802.1x technology that requires authentication from clients. Lack of dependence on applications - The IPsec technology does not depend on applications to become effective, as the s=entire system is operated at the network level. As such, it avoids compatibility issues, which are common in 802.1x systems. Broken algorithms - A number of key algorithms used by the IPsec have been cracked,
