The case of European Court of Justice Free Essay Example, 2000 words

Theories of actuarial science have been used since the advent of modern-day insurance. Actuarial science can provide general insight into risk management issues (Poitras, 2002). It examines situations where the chance of loss or no loss is considered. The concept of insurance is hinged on the aspect of risk sharing (pooling of risks). Insurance often uses actuaries to perform risk assessment and determine the level of premiums that an individual need to pay according to risks that may occur. Different people from different occupations are predisposed to different risks. Therefore, insurance companies find it difficult to assign a uniform premium rate to clientele in the same pool since these clients suffer different levels of predisposition to the same risks. The ECJ made a final ruling that determined that the offering of different insurance premiums or other benefits based on gender are a violation of the fundamental right to equal treatment. In this ruling, the ECJ; the highest E uropean court, barred European insurance companies from pricing premiums differently based on the sex of prospective policyholders. Women tend to obtain cheaper premiums as they attributed to as a low-risk group.

The court ruled that the rules were not compatible with Article 6(2) of the Treaty. The decision by the ECJ on the insurance discrimination case was met by inflamed opinions concerning the authority of supranational European legal bodies (Lui, 2011). The case based on Council Directive 2004/113 implementing the principle of equal treatment of both genders in the access to and supply of all goods and services. According to Wagner (2011), a directive, in European law, tells member states on what they ought to achieve but the details on how to go about the achievement are left to the member state to decide.

Essay on An Exploration of Love Poetry - 1691 Words

An Exploration of Love Poetry Coursework Poetry is an idiosyncratic way of a person trying to articulate their feelings or other in a different way about a variety of topics, love, past experiences, politics etc. With the use of metaphors and similes, one can show diverse things without having to be precise about them. Not just words can tell us about the poem, a lot of the time we can learn how the poet is trying to express themselves, by looking at the sentence composition, how it is laid out, how many lines there are, etc. The roles of the masculine and feminine civilization in society were remarkably dissimilar through a long period between the 16th and 17th century.

The characters in the poems both see women as sexual objects; furthermore they both try to show men as the stronger and more influential sex. These two poems convey their message in very dissimilar styles. The two poems use very different arguments to try to persuade the woman to do similar things. These two arguments are close to being completely the opposite even though they are trying to achieve the same thing. Marvells playful entanglements of sex and condescension are conspicuous in his metaphysical poem. He achieves this by using overwrought similes outsized metaphors and hyperboles for example, an hundred years, like amorous birds of prey and vegetable love.

McDonald, unethical marketing free essay sample

McDonald is the largest leading multinational fast food restaurant with more than 33000 food chains worldwide in 119 countries, serving 68 millions of customers daily. Despite McDonald’s prevalent brand name under globalization, many of its marketing strategies are come into question in terms of ethnicity. In the following essay, some of those unethical issues of McDonald being criticized will be analyzed based on the values-oriented framework, which refers to the AMA Statement of Ethics and ICC International Code of Advertising Practice. Successful marketing could seize the opportunity according to the need of the public, giving people what they want while maintaining profitable. In response to the changing customer tastes towards a healthier life style, McDonald has provided healthier and low calories options like salads and fruit. It also offered larger variety of nutritious food in Happy Meals. (G. M. Cheeseman, 2011) All these are the marketing strategies McDonald adopted in order to establish a health-friendly brand image. We will write a custom essay sample on McDonald, unethical marketing? or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page According to the AMA Statement of Ethics, marketers should embrace ethical values like honesty, fairness, responsibility and transparency. For honesty and fairness, McDonald does not offer food of nutritious value as it claims in its advertisement. Deceptive advertising strategy is used to depict that its food is healthy for daily consumption. In spite of McDonald’s willingness to disclose the nutrition information of its food, the customers will never be acknowledged of the use of additives, preservatives and chemical value added to the food, which may adversely affect our health upon over-consumption. For instance, it had been discovered that chemical ingredients like preservative TBHQ is contained in McDonald’s nuggets. (CNN Health, 2010) Transparency is undoubtedly violated given that McDonald’s intention of trying to conceal the harmful production process and risk of food consumption. On the other hand, the recent introduction of the â€Å"Super Captain† meal is known as fattening as 6 bowls of rice, supporting the fact that McDonald will hardly be a healthy choice. Apart from the unauthentic advertising of its nutrition value, McDonald also employs the â€Å"limited availability† and â€Å"back due to demand† marketing tactic to facilitate the demand of the product. Knowing that the product would soon be unavailable, people would rush to try out so as to ensure that they would not miss anything. (K. Johnson, 2012) Fairness and responsibility are infringed given that McDonald is trying to seek financial profit to the detriment of the nations health. Marketing to children is another issue that McDonald has long been criticized and accused of. Including toy in Happy Meal is one of the marketing strategies directly targeted to children. The lure of toys and cartoon charterers in the advertisement can be acted as an inducement for them to consume the meal, which has direct relationship to childhood obesity, diet related diseases and other impacts on children’s health. (G. O. Brien, 2011) However, most of the McDonald advertisements are usually aired during kid’s programming afternoon sessions. It is believed that children are vulnerable to marketing and they are immature enough to understand the marketing tactic nor having the final purchasing power. Restriction and legislation concerning marketing to children therefore exist. According to the consolidated ICC Code regarding the marketing to children, products inappropriate for children should not be advertised in media targeted to them. On one hand, fast food eating culture should not be encouraged to the young people given its negative impact to health. On the other hand, it is unethical to leave parents out of the marketing strategies. (C. Smith, 2010) To conclude, unethical marketing strategies and marketing to children should be strictly prohibited given its adverse impact to the society. In fact, we can see that McDonald has put its effort towards establishing a healthier and more marketing ethnical publicity comparing to years back. However, further improvement can still be made. Multination Corporation like McDonald which has immense impact on the society should have the responsibility to be a leader in ethical marketing.

The Giver Givers Essay Example For Students

The Giver Givers Essay The Giver onas lives in a perfect world where war, disease, and suffering have all been eradicated. Everything is in order; everything is under control. The people have no worries or cares. The Community strives for sameness, in which everyone and everything are the same and equal. To help the Community function as a cohesive unit, each member is assigned a position in society. When Jonas turns twelve, the Community selects him to be the new Receiver of Memories. Only the Giver knows the truth and memories of the past, and now he must pass these memories on to Jonas. We will write a custom essay on The Giver Givers specifically for you for only $16.38 $13.9/page Order now The Giver is a wonderful book. Lois Lowry skillfully crafted an intriguing and profoundly thoughtful story. She subtly creates an uneasy feeling that something is wrong with this perfect world. The Communitys advisors intend to establish security within utopian society, but they really establish a stifling dystopia. To protect people from the risks of making poor or wrong decisions in life, the advisors plan and dictate the lives of the people. In effect, the citizens have no freedom of choice; they do not choose their job or even their spouse. Moreover, the advisors inhibit the peoples ability to feel because they want to spare them from the hardships and pain of life. For instance, individuals must take a pill everyday, which suppresses passionate feelings. The citizens do not know or experience true emotions like love. One of the goals of the Community is to achieve sameness so that no one feels embarrassed or gets excluded for being different. However, this limits individuality and freedom of expression because everyone conforms to a certain desired image. Finally, to relieve the population of the horrors and devastation of the world and the past, the advisors isolate the Community from the rest of the world (also known as Elsewhere) and give the burden of holding the memories of the past to a single member of society: the Receiver. Therefore, the Community lives only in the present, and the people have a narrow perspective of life because they only know their community and way of life. They are naive; they do not gain knowledge or wisdom from the memories. While receiving the memories, Jonas learns a different and better way to live and realizes what he and the Community have been missing. He decides that something must be done to change the current conditions and enlighten his community. Although it is a Newbery Award Winner, The Giver is a controversial book that has been challenged and even banned. After parents complained that the violent and sexual passages were inappropriate for children, the Bonita Unified School District in California temporarily banned the novel from classes. The Giver has been challenged in other school districts around the country for its mature themes of euthanasia, infanticide, and suicide. I do not agree with banning and challenging of this novel. It is a great book, and part of what makes it so great is the incorporation of these controversial issues. They force readers to wrestle with their own thoughts and figure out their stance on the issues. Good literature makes readers think. Banning this book takes away the freedom of speech, the freedom to read, and the freedom to learn and explore. The banning of The Giver is ironically similar to the actions of the Community that lead the Community to its suppressive and stifling state. A powerful story, The Giver keeps readers in suspense, touches them, and stays with them for a long time. I love this book, and I encourage everyone to read it. .

Canadas Growing Autonomy †Sociology Essay

Canadas Growing Autonomy – Sociology Essay Free Online Research Papers Canadas Growing Autonomy Sociology Essay The twentieth century was a turning point in Canadian history as Canada went through many changes, including economic, and population growths. Today Canada has a position in the world as one of the middle powers. This was achieved by great progress on many fields during the twentieth century. The three most prominent events during the twentieth century which have helped Canada slowly drift away from Great Britain are the King-Byng affair in 1926, the Statute of Westminster in 1931, and finally the creation of Canada’s own flag, in 1965. In the twentieth century, Canada has grown increasingly autonomous from the United Kingdom. In 1926, the King-Byng affair was a great step forward in Canada’s independence from Britain. It all began when Prime Minister Mackenzie King asked the governor general, William Byng, to dissolve parliament and call a general election, where he refused (Wales). As a result of Byng’s refusal, King ensured that, once back in power, he would strip certain powers from the governor general. This would make Canada more independent from the Queen and Britain. This event has changed the way the job of the governor general has been carried out throughout the twentieth century (Wales). After this event Canada could freely pass laws and bills, without fear of intervention by the governor general. As King said after the affair, â€Å"It is a complete control by an individual† about Byng (The National). This showed the kind of power the governor general had before this event, where as now he/she must accept the laws given to be signed. The King-Byng affair is one major event where Canada has moved forward in its independence from Great Britain because Byng refused to call an election, it changed the job of the governor general, and it reduced the amount of power this job has. The statute of Westminster, in 1931, was another step forward in Canada’s autonomy from Britain. This statute removed some restricting acts from the past which restricted Canada’s independence including the Colonial Laws Validity Act of 1865 (Wales). This meant that Canada did not have to follow all the British laws created in Britain. This gave Canada more freedom and independence. As stated in the statute: â€Å"No Act of Parliament of the United Kingdom passed after the commencement of this Act shall extend or be deemed to extend, to a Dominion as part of the law of that Dominion, unless it is expressly declared in that Act that Dominion has requested, and consented to, the enactment thereof.† (Wales) This gave Canada the privileges to not follow all the same rules as the United Kingdom giving Canada more independence. This document gave all former dominions of the United Kingdom equal independence from the UK (Hallowell, 598). All former dominions had equal i ndependence because they could now freely create their own laws without the UK looking over their shoulder throughout the whole process. The statute of Westminster has helped Canada’s independence come a long way because it removed binding acts from the past, gave way for Canada to create their own laws, and gave all former dominions equal independence as the UK. When Canada created their own flag in 1965 they furthered their independence than ever before. The old flag, the Union Jack showed great ties with the United Kingdom because it had a strong bond with the UK (Wales). After the flag was created, the strong bond between the UK and Canada in their flags was broken and Canada was able to use and display their own flag. With the creation of the new flag Canada had their own flag to fly at international events (Wales). With the new flag Canada showed their independence from the UK in international events, such as the Olympics where Canada was respected for their own flag. Canada now had an original symbol to represent their country (Halowell, 428). The maple leaf is now Canada’s symbol which shows great autonomy from England because they are thought of being their own country without any affiliation with the UK. Canada’s new flag was a great step forward in Canadian independence from the UK because strong ties in the union jac k was demolished, it gave Canada something to be represented by, and Canada become known as its own country instead of a country with a back bone in England. Canada has grown increasingly independent from the UK throughout the twentieth century. Canada’s growing autonomy has been shown through the three important events discussed above: which are the creation of Canada’s flag in 1965, the Statute of Westminster in 1931, and finally the King-Byng affair in 1926. Canada should be greatly accredited for its increasing autonomy but on the other hand this process has been very slow. In addition, Canada still has many ties to the UK, which must be removed permanently for Canada to become its own independent country, with no backbone support by England.

Procompsognathus - Facts and Figures

Procompsognathus - Facts and Figures Name: Procompsognathus (Greek for before the elegant jaw); pronounced PRO-comp-SOG-nah-thuss Habitat: Swamps of western Europe Historical Period: Late Triassic (210 million years ago) Size and Weight: About four feet long and 5-10 pounds Diet: Small animals and insects Distinguishing Characteristics: Small size; bipedal posture; long legs and snout About Procompsognathus Despite its namebefore Compsognathusthe evolutionary relationship of Procompsognathus to the later and much-better known Compsognathus is uncertain at best. Because of the poor quality of this dinosaurs fossil remains, the best we can say about Procompsognathus is that it was a carnivorous reptile, but beyond that, its unclear if it was an early theropod dinosaur or a late archosaur akin to the bipedal Marasuchus (and thus not a dinosaur at all). In either event, though, Procompsognathus (and other reptiles like it) certainly lay at the base of later dinosaur evolution, either as direct progenitors of this fearsome breed or great-uncles a few times removes. One of the little known facts about Procompsognathus is that it was this dinosaur, and not Compsognathus, that had cameos in Michael Crichtons novels Jurassic Park and The Lost World. Crichton portrays compies as slightly venomous (in the books, Procompsognathus bites render their victims drowsy and ready for the kill), as well as eager consumers of sauropod poop. Needless to say, both of these attributes are complete inventions; to date, paleontologists have yet to identify any venomous dinosaurs, and there is no fossil evidence that any dinosaurs ate excrement (though its certainly not outside the range of possibility).

Managing Human Resources in Health and Social Care Essay

Managing Human Resources in Health and Social Care - Essay Example 1.1) Planning a recruitment drive for health facility workers is a crucial process of obtaining the best possible workforce. Every health facility desires the best for its optimum operations. A facility planning to hire health workers, therefore, needs to create an environment that attracts its target labor force. Most workers usually discern good employers from the amount of money the employers pay. Being a health worker, however, is more of a calling than mere employment opportunity for dedicated health and social care givers. Social care workers derive more fulfillments from results of what they do than the pay they get from it. The period of recruitment should be preceded by an extensive publicity campaign intended for the target workforce. Healthcare or social facilities planning to carry out recruitment should pre-package its success stories and present them to a local media house. The same stories should be produced in newsletters, facility website and the social media. There should also be a spotlight on healthcare providers considered icons by the society. These service heroes should tell of their fulfillment and joy derived from working for the institution. As mentioned before, health and social work is a sacrifice, and individuals value fulfillment more than earnings. The facility needs to rely on its representatives and associates to take their image message to masses. An example is a facility that cares for the aged. Major drive to work for such institutions is service to humanity. They should work at improving their image to attract required qualified staff by portraying a superior picture. The institutions cannot afford to entice workers with heavy payment packs, and, therefore, have to prove their ability t o provide an environment for self-satisfaction for their prospective staff. 1.2) Other than

Mary Shellys Frankenstein Essay Example for Free

Mary Shellys Frankenstein Essay Mary Shellys novel is structured in a way, which attempts to give authority to her views. Opening with an authors introduction, and supported with a preface with her famous husband. Mary Shellys novel starts with a series of letters claiming to know the truth of Victor Frankensteins story. This family involvement, followed by professional distancing, reveals the strength of the authors feelings on the responsibilities of family and scientists. For a century and a half, many readers of the Mary Shellys novel Frankenstein have debated over which character could be associated with the expression Monster. Mary Shelly said in the preface the reason why she produced this nineteenth century novel was a ghost story oh! If I could only contrive one which would frighten my reader as I myself had been frightened that night. She wanted her readers to feel the terror that she had dreamed one night. The readers of Mary Shellys novel Frankenstein might believe that the creature is the monster, however there are two potential monsters in the novel. These two characters from the novel are the Creature itself and the creator of the creature, Dr Victor Frankenstein. One candidate who might be believed to be the monster is Dr Victor Frankenstein. At the age of seventeen Victors parents suggested that he should become a student at the university of Ingolstadt. Unfortunately Victors mother passed away while giving birth to his brother. The death of his mother shocked him and caused him to search for ways to extend life. After the death of his mother, Victor took his parents advice and went to university. My departure for Ingolstadt which had been deferred by these events it appeared to me sacrilege so soon to leave the repose, akin to death, of the house of mourning and to rush into the thick if life. This suggests he wasnt sure if it was the respectable move to make, to leave his mourning family behind and go off to university. While at university Victor became fascinated in biology: One of the phenomena, which had peculiarly attracted my attention was the structure of the human frame, and indeed any animal endued with life. Victor was focused to stop death. He was grieving so much because he had lost someone so important and close to him: I thought that if I could bestow animation upon lifeless matter renew life where death had apparently devoted the body to corruption. His fascination with extending life overtook his studying; he became so committed to finding a way, he had set himself a challenge and he was so sure to achieve that challenge. A time in the novel where we are shown that Victor is related as a monster is the time when he begins to dig up the dead and raid graveyards. Who shall conceive the horrors of my secret toil as I dabbled among the unhallowed damps of the grave or tortured I collected bones from charnel-houses secrets of the human frame. This is a sign of immoral, abnormal attitude and is offensive towards the bodies. The definition of a monster is a misshapen animal or plant; person of wickedness; huge animal or thing. The part of the definition where it says a person of wickedness is what should be used to describe Victor Frankenstein. No normal person would dig up the dead and use body parts to make a creation. Another way, in which Victor could be considered as the monster is the way he treated the creature once he had brought it to life. Victor disowned the creature; he refused to acknowledge it and to accept that the creature was his own: For this I had deprived myself of rest ad health. I had desired it with an ardour at length lassitude succeeded to the tumult endeavouring to seek a few moments of forgetfulness but it was in vain. Victor had no intention of caring for the creature, it was as if he was afraid of his own creation. He discards the Creature immediately after its creation, calling it a wretch and leaving it to fend for itself. This shows how irresponsible he is. It is also another example of him neglecting his family, since the Creature sees him as its father. The creature approaches Victor like a baby would to its father: He held up the curtain of the bed; and his eyes, if eyes they may be called, were fixed on me while a grin wrinkled his cheeks. How could Victor abandon the creature, he had no sympathy towards it. The way in which the creature is described when it approaches Victor is just like the way a baby would approach its parents, maybe at this part of the novel, we readers are to feel sympathy for the creature and to consider Victor as the monster for the way he treated the creature, it was his own creation he should of cared for it and been its companion. Victor should of treated the creature like his own child, possibly if he did show care for the creature and not show fear, maybe the creature wouldnt have been so vile because he knew no different. The creature didnt know how to treat or care for other people. So really it wasnt the creatures fault for the deaths caused and for the way in which he treated people because overall he didnt know any different and wasnt taught by Victor how to treat others.

THE SELLING OF ORGANS: RIGHT OR WRONG :: Ethical Issues, Human Organs

I Introduction All humans have organs. The organ is very important to the humans because without organ humans will not be able to live well. At present, there are many actions that are done by irresponsible people to sell organs. Organ sales cases occur when a person sells or transfers an organ from one body to another body for the purpose of replacing the recipient’s damaged organ. There are thousands of people dying to buy a kidney, and thousands of people dying to sell a kidney because of the lack of organs availability. Lives should not be wasted, they should be saved.

Mark powers Period 2 C physics March 17 Thermodynamics lab I. The purpose of this experiment is to keep a certain amount of water as hot as possible for as long as possible. We also get to use whatever materials we want as long as our product is or is smaller than 20cm. II. For my project I used Styrofoam, tinfoil, insulation, silicone, and a cork. I used the Styrofoam as a box to put the can in and the Styrofoam also acts as a thermal insulation. I used the tin foil because it serves as an insulator and keeps the radiant heat inside the box.Next I used insulation, which does what its name is, it keeps whatever inside of it insulated or prevents convection. I used silicone to block off the holes from the Styrofoam to make a good box for the heat to stay in. finally I used a cork on the top of my can to have the smallest hole for the heat to escape it. III. For this experiment I used Styrofoam, tinfoil, insulation, silicone, and a cork. I also need a thermometer to measure the change in temperature of the water during the course of the experiment.IV. First I cut out Styrofoam to the appropriate lengths and made sure it wasn’t over the 20 cm limit. I then covered the Styrofoam with tin foil and sealed off all the cracks on the inside with silicone. After that I put insulation on the whole inside of the box with enough room to put the can in on the inside. I finally added a cork on the top of the can to make the smallest opening so that the heat had little room to escape to conclude my project. Time| Temperature (C °)| 0 minutes| | 20 minutes| |V. Data VI. 1. I think the most important type of the 3 types of energy transfer that we had to minimize was convection because convection is heat transfer via heating surrounding fluid and then the fluid moves. 2. The sun doesn’t heat us through convection or conduction because for heat to heat through conduction it need to be touching it and we don’t touch the sun, and for conduction is heat transfe r via heating surrounding fluid and then the fluid moves but us humans are solids, not liquids. . Mammals that live in cold climates and cold water insulate themselves with their fur and being cold blooded. The mammals that don’t live in water use their fur as an insulator to keep their warm air inside them and keep the cold air outside, and the cold-water mammals usually are cold blooded so that their temperature doesn’t really change with the cold conditions that they are around all the time. VII. Thermodynamics Lab Abstract: This report will show the acquired understanding of the refrigeration cycle by using first and second laws of thermodynamics. In order to analyze this system several assumptions where made such like an isentropic process at the compressor an isenthalpic expansion in the throttling valve. Diagrams will be provided to depict these thermodynamic processes in addition to computing the heat transferred to the system and the work input to the compressor.

Also, determent the heat transfers by using the mass and energy balance. Introduction: The term â€Å"refrigeration† may be defined as the process of removing heat from a substance under controlled conditions. It also include s the process of reducing and maintaining the temperature of a body below the general temperature of its surroundings. In other words, the refrigeration means a continued extraction of heat from a body whose temperature is already below temperature of its surroundings.In this lab 1,1,1,2-Tetrafluoroethane (R-134a) was used as refrigerant. Since energy cannot be destroyed according to first law of thermodynamics. In a refrigerator, heat is virtually pumped from a lower temperature to a higher temperature. According to Clausius Statement of Second Law of Thermodynamics states that heat will not pass cold to hotter region without the aid of an external agency. Thus, process can only be performed with the aid of some external work. It is thus obvious that supply of power is regularly required to drive a refrigerator.Theoretically, a refrigerator is a reversed heat engine or a heat pump which pumps heat from a cold body and delivers it to a hot body. The substance, which works in a pump to extract heat from a cold body and to deliver it to a hot body, is known as refrigerant. Description of Refrigeration cycle description: Most commonly used refrigeration/heat pump cycle and involves the same four processes as a heat engine cycle but in the reverse order (i. e. evaporation – compression – condensation – expansion/throttling).Figure 1 gives a schematic representation of the four essential mechanical components in this cycle. Heat out 3 2 Condenser Throttle Work in Valve Evaporator Compressor 4 1 Heat in Figure 1: Refrigeration Cycle components Compressor: The compressor in a refrigeration system is essentially a pump. It is used to pump heat uphill from the cold side to the hot side of the system Condenser: The condenser or cooler consists of coils of pipe in which the high pressure and temperature vapour refrigerant is cooled and condensed.Expansion valve: As the high-pressure high temperature liquid refrigerant passes the throttling valve seat ing, its pressure and temperature drop to that of the evaporator. The drop in temperature is changed liquid phase to a mixture of low-pressure and temperature liquid and vapour enter the evaporator without any change in enthalpy Evaporator: The purpose of the evaporator is to remove unwanted heat from the product, via the liquid refrigerant 3 2 4 1 Superheating Sub-cooling Critical Point Liquid Pressure Enthalpy 3 2 4 1 Superheating Sub-cooling Critical PointLiquid Pressure Enthalpy Figure 2: Refrigeration cycle on pressure – enthalpy diagram. In cycle the refrigerant vapour is compressed to a higher temperature and pressure (12). The compressed vapour is then condensed isobarically which results in heat rejection to the surroundings (23). The next step is the adiabatic throttling of the refrigerant to the low temperature and pressure (34). The final step is where the refrigerant is evaporated at low temperature and pressure, which results in the absorption of heat from its s urroundings (41). Theory /Analysis:Figure 3 According to first law of thermodynamics energy (heat, work), cannot destroyed but energy changing from one form to another. ?H+? Ke+? Pe=? Q+? W (1) (Balmer, 2011) Where H=enthalpy, K=kinetic energy, P= potential energy, Q= heat and W= work. In order to simplify the calculation for the energy balance, the following assumptions were made: – Kinetic and potential energy changes are negligible throughout the system So, ?H=? Q+? W – In a constant pressure for the condenser (work=0). The heat transfer of the condenser is the heat loss, in other words Q2-3 and is given by:Q2-3= m(h3-h2) – In a constant pressure for evaporator (work=0), he heat gain by the evaporator is equal to Q1-4 and is given by: Q4-1= m(h1-h4) – The work done by the compressor is the same as the work in the cycle and is given by: Q1-2= (h2-h1) – The power drawn by the compressor defined by the following equation: Power= Voltage ? Current ? Power Factor – Coefficient of performance is defined as: COP=Q4-1? Q2-3? -Q4-1 (2) (Balmer, 2011) -The heat transfer water can be calculated from the water flow rates and temperature changes using the following formula where Cp is specific heat capacity:Q= mCp ?

During this process the T2 temperature of refrigerant decrees from. We know that during isentropic compression, no heat is absorbed or rejected. The refrigerant is now (compressed/ evaporated) isobarically (P2 = P3) and (P4=P3) as shown by the p-h.

After that refrigerant exit the evaporator in saturated vapour. In a isobarically process 4-1 as shown by the p-h Result:Discussion: It was seen in the refrigeration cycle; Carnot cycle and the Ideal cycle there are different coefficients of performance on refrigerant. If we look at COP formula the low heat is divided by the work in in this case where the refrigerant entered the compressor could significantly hinder the performance of this component by change (superheating). Also the refrigerant leaving the condenser will effect the COP (sup-cooling) . If we compare Carnot cycle to the actual cycle, in Carnot refrigerant super- heating has increased, which will increase the COP.In the other hand, in Ideal cycle the sub-cooling has decreased which the sub-cooling decrease the liquid during expansion to saturated liquid-vapour and increases the refrigerating performance, but by decreases the sub-heating in the evaporator exit from vapour to saturated vapour. Which in this case the COP decreased but it will be higher that the actual cycle. The heat transfer occur in the basic refrigeration cycle, by calculate the energy balance in the cycle. The sum of the energy will not be even close to zero and this violates the first law of thermodynamics.So, there is heat lost in the cycle according to the second law of thermodynamics, heat always flows from a material at a high temperature to a material at a low temperature. For heat to transfer there has to be a temperature difference between the two materials. This heat can be calculated by Convection is the transfer o f heat from one place to a different location by circulating it with a fan or natural movement. Figure 6:Temperature vs. distance condenser Figure 7: Temperature vs. distance evaporator In figure 6 and 7 shows the heat exchange, in figure 6 the cold-water flow co-current with the hot refrigerant.With both entering the same end. This application will be useful to if we want a limited outlet temperature. It’s also useful to drop more quickly temperature because the large difference in the temperature. Where in figure 7 the hot-water flow countercurrent with the cold refrigerant the temperature is achievable by the cold stream can never exceed that of the hot steam. (Ulrich, 2004) Conclusion: This experiment was carried out in order to observe the properties and functions of a refrigeration cycle. With the properties of the refrigerantR134a at all the stages of the refrigeration cycle known, the heat transfer at the condenser and evaporator were calculated. The heat absorbed by the system (evaporator) was determined to be 16 w. The heat given off by the condenser was calculated to being -73. 46 w. The work done by the compressor was also calculated to being -60. 19 W. With this, the refrigeration performance of the cycle was calculated and was equal to 4. 42. Works Cited Balmer, R. T. (2011).

Definition of Politics Essay

The art and science of government; dealing with the form, organisation and administration of a state or part of one, and of the regulation of its relations with other states†¦political [means] belonging to or pertaining to the state, its government and policy. Oxford English Dictionary. There are two types of political systems, the Centralised political system, and the Decentralised political system. The centralised political system is a means to run the country under central control, with no local authorities creating rules and regulations for a specific area, an example of this is the former Soviet Union, or modern China. This ruling is known as communism. Sports in communist countries are controlled in the same way as any other social agencies, such as education. Sport was used for boosting morale, production, and effectiveness of the military and to provide a successful image for their regime around the world. The athletes of the communist bloc regimes dominated world sport for many years until the cold war ended. A decentralised political system is one where the administration of government is re-organised into smaller autonomous units such as local authorities in the UK and individual states in the USA. Each area decides its own policies on sport provision and effectiveness of sport in schools. Many sports people see sport as a means of escaping every day life, which is controlled by the government and do not which to see sport controlled except by their own governing, bodies e.g. IOC, FIFA. However, government influence cannot be avoided in some circumstances. Sport has been used for government propaganda purposes, for example the Nazi propaganda in the 1936 Olympic Games, which Hitler used to promote his Nazi ideals. In Russia, the government insisted that a fitness campaign called â€Å"Ready for labour and defence† was compulsory for all its citizens and was still operational in the latter half of the 20th century. In our own country, following heavy losses in the Boer war, it was felt that the military was not fit enough and so compulsory fitness exercises was instigated in all state schools in the early 20th century to improve the fitness of the working class. More recently, we can see how politics and sport cannot be separated when the English cricket team pulled out of a group match due to political unrest between Zimbabwe and England. Sport can be used to introduce or reinforce social harmony. By introducing good sporting facilities into areas that have suffered unrest, the government hopes to lure youths to use the facilities wisely in their spare time rather than be involved in anti-social behaviour. The governments Education Act of 1988 affected the provision of sport in schools. The conservative government wanted more control over the teaching of physical education in schools and produced a report called â€Å"Raising the game.†Ã‚  In reality, sport needs politics as much as politics needs sport. For example, the government can provide finance and locations to stage major sporting events such as the Olympics and the World Cup. In return, sporting teams who perform well promote a country to the rest of the world, and raises national pride. All beneficial to any government. Drugs have been used throughout history, since the time of the Greeks and Romans who took substances to improve their performance and so it is not a modern problem. However, drug use in modern sport has become more widespread, and is now shown to be a problem across all the sports and in both genders, at both amateur and professional levels. An increase in drug use came about through various factors such as advances in biology and medicine, the use of drugs in WW2, the development, and availability of testosterone steroids and growth hormones in the 1950’s. Weight trainers saw the potential of these drugs and used them to their own advantage and other athletes were able to see the potential of using drugs to improve their own play e.g. snooker players used beta-blockers to steady nerves.

Man vs. Himself essays

Man vs. Himself essays Self-fulfillment is what people live for, without it how can a person live? A failed search for self-fulfillment often leads to death. Demonstrated in A Tale of Two Cites, Hamlet, and A Death of a Salesman, each novel includes one character that struggles to fulfill his life, which results in death. Self-fulfillment can include being loved, wealthy, happiness, remembered, respected, or even a being hero. Sadly if none of these objectives is met, the character seems to think death is the only way option. Nothing great will ever be achieved without great men, and men are great only if they are determined to be so as said by Charles DeGaulle, relates to each character in the three novels that they were never determined to improve their life. The first example of failed self-fulfillment resulting in death is Willy Lomans from the novel A Death of a Salesman. Loman fails to be well-liked and also fails to provide for his family and decides that the only way to provide for them is to commit suicide so they can collect the insurance money. Loman spent most of his life trying to convince his family that he is the best in the business and he wants his sons, Biff and Happy to be the same. Willy tells his sons that with his success hell be Bigger than Uncle Charley! Because Charley is not liked. He's liked, but he's not well liked.(Miller, I.iii) Little do Biff and Happy know, that their father isnt liked at all, hes just trying to fulfill one of his goals in life, being well-liked. Later when Loman is fired from his job he starts to think about all the hard work hes contributed to wanting to become successful and then concludes that, Funny, y'know? After all the highways, and the trains, and the appointments, and the yea rs, you end up worth more dead than alive.(Miller, II.iv) Now Willy starts to see death as the only way to provide for his f...

Impact of WWI on European Society Essay Example | Topics and Well Written Essays - 750 words

Impact of WWI on European Society - Essay Example This paper briefly analyses the impacts of WW1 on European society. The total deaths of all nations who fought in the WW1 are thought to have been 8.5 million with 21 million being wounded.  Alongside these statistics, was the fact that vast areas of north-eastern Europe had been reduced to rubble. Flanders in Belgium had been all but destroyed with the ancient city of Ypres being devastated. The homes of 750,000 French people were destroyed and the infrastructure of this region had also been severely damaged. Roads, coal mines, telegraph poles had all been destroyed and such a loss greatly hindered the area's ability to function normally (The Treaty of Versailles). Apart from the 116,000 American soldiers, all the other soldiers killed in the WW1 were from Europe. In other words, Europe suffered heavy casualties as a result of WW1. It should be noted that along with the loss of lives, Europe faced a lot of destruction of its properties. The return of war prisoners after WW1 caused many social problems in Europe. Millions of Europeans were in jails after WW1. They forced to spend longer periods in jails even after the end of WW1. Decades after the end of WW1, they got freedom and their return caused new social problems in Europe. â€Å"Emaciated and physically broken, they experienced psychological and material difficulties adjusting to normal life. Their spouses had often remarried. The state aid they received after the release was insufficient and they failed to get new employment† (Paxton, & Hessler, p.472) â€Å"The birth rate in Northern and Western Europe declined by one half after the WW1† (Paxton & Hessler, p.18). It should be noted that the birth rate reduced considerably after WW1 since European couples were either separated after the war or failed to engage in sexual activities because of the physical and psychological trauma caused by this war. Moreover, European women forced to come out from kitchens and work in the factories just l ike men after WW1. They started to lead a more independent life after WW1 (Paxton & Hessler, p.20). Such free life helped them to avoid pregnancy and forced sexual activities. The 1919 Treaty of Versailles was instrumental in ending WW1. It was signed on 28 June 1919. This treaty created a lot of controversies in Europe, especially in Germany. It puts the entire blame on Germany for causing WW1. It forced Germany to concede many of its lands and pay heavy compensation to certain countries. The "Big Three" (David Lloyd George of Britain, Clemenceau of France and Woodrow Wilson of America) were responsible for the preparation of the clauses of Treaty of Versailles. The Big Three were keen on humiliating German feelings as much as possible. In fact, they were concerned about the rise of communism in Europe and they tried to block the spreading of communism in Europe through this treaty. Some people believe that the controversial clauses in the Treaty of Versailles were the exact reason for the occurrence of WW2. Hitler, through his inspirational speeches, injected nationalism in the veins of Germans. He argued that German culture is superior to other cultures and hence Germans have the right to rule the world. He had pointed out that the allied powers caused shame to Germans while forcing them to accept the responsibilities of WW1. In short, the end of WW1 actually prepared a way for WW2.  

Why was Ulysses S. Grant so successful in finally ending the Civil War Research Paper

Why was Ulysses S. Grant so successful in finally ending the Civil War - Research Paper Example Some of them argued that the major issues of the conflict are related with the rights of the States, and others underlined the fact that quandary of slavery had paved the way of American Civil War. However, by the end of 1860s, one can find Ulysess S Grant making a personal mark in the history of American civil war, blowing a series of battles, conquering a Confederate army and earning the status of an antagonistic military general. Grant’s stubbornness and self reliance contributed stability in success and that helped him to mark his name in the history of American Civil War and the ultimate success is coined with Grant’s army. Grant’s idea of total war helped him to maintain consistency in the battlefield. It is a part of common knowledge is that a war place is filled with turmoil and sufferings. The haunting sounds of guns and the frustrated whispering of officials characterize the battlefield. A military general has the duty to stand lonely in the middle of t hese commotions with fear, anxiety, suspicion, and official responsibility. As an experienced military general who witnessed in the American Civil War at close quarters Ulysses S. Grant was better equipped to triumph over the barriers of the battlefield through his war policies and brilliant administrative tactics. Grant succeeded to gain the support from the President Lincoln, leaders of Republican Party, the Media and a significant number of common people in the United States. Grant’s efforts to use the federal army or legislation to preserve the rights of blacks paved the way for White’s aggression and opposition. However, political and material backgrounds during the time of 1860s paved the way for the success of Grant’s army. Thus, one can note that Grant’s domestic political transactions, foreign and domestic policies, professional tactics and his innate abilities were instrumental in his success in American Civil War. American civil war which is

Final Project Reflective Paper - Team Beta Assignment

Final Project Reflective Paper - Team Beta - Assignment Example Consequently, it is a suitable platform for human resource managers to evaluate their progress and effect adjustment in their human resource management strategies. Management Introduction While implementing projects in new environments, any organization will require to strategize on how to manage its resources including the human labour in an effort to penetrate the market and compete with the external and internal market forces. The human labour is a crucial element of any business, and its management and effective utilization has a direct impact on the organization’s success. The productivity of human labour in all the phases of project implementation lies on the shoulders of the organizational managers. The role of human resource manager in an organization is to recruit, train, monitor, evaluate and motivate the employees during the project implementation process. The performance of an organization will depend on its ability to exercise effective organization behavior and s kills while managing teamwork among the role players within the system. To do this, a company will require to conduct a SWOT analysis as a strategy of re-evaluating its effectiveness in gathering its strengths, neutralizing its threats and weaknesses and grasping its opportunities presented in the environment. Effective team management and organizational behavior are the basic elements that the human resource management must possess in order to survive in the diverse market. Just like any other organization, Team Beta has faced the challenge of managing the team players during the implementation of its performance based scenario planning project. To maintain teamwork within the four members who have a variant cultural background is a credit worth effort that requires effective management skills that can stand the tests of a harsh project environment. The purpose of this article is engage in a critical reflective practice that Brookfield (1998) terms as an effective procedure to chec k the success of any team leader at each stage of a project. Organizational Behaviors and Skills Required in a Successful 21st-Century Organizational transformation is an element of business that an organization cannot ignore in the 21st century. With the proliferation of technology the barriers of business boundaries have become a thing of the past and the world has condensed into a small village. This is a century that has been dominated by trade globalization and extension of business boundaries to feature international business markets (Kreitman, 1997). These changes have had a great impact on trade and organizations are under the pressure to readjust their organizational behavior to suit diversified business environments that are characterized with unpredictable market forces. In team management, it is important to adopt a behavior that suits the modern approach of team management. One challenge that arises team management is the understanding of the available labour force, its management and motivation of the role players. Global diversity management advocates that team leaders provide opportunities for each employee to grow and develop within the organizations that they work in. It requires that the organization takes

Functional Relationship Network Architecture

Functional Relationship Network Architecture A computer network, is referred to as a network, it is a harvest of computers and instruments interconnected via communication channels that enables communications among users and permits users to allocated resources. Networks may be classified according to a wide range of characteristics. A computer network permits sharing of resources and knowledge among interconnected devices. Fig1:Block diagram of computer network Connection method Computer networks can be classified according to the hardware and software engineering that is accustomed to interconnect the individual devices in the network, such as optical fiber, Ethernet, wireless LAN. Functional relationship (network architecture) Computer networks may be classified according to the functional relationships which exist among the elements of the network, e.g., active networking, client-server and peer-to-peer architecture. Network topology Computer networks may be classified according to the network topology upon which the network is grounded, such as bus network, star network, ring network, mesh network. Network topology is the coordination by which tools in the network are organized in their rational family members to one another, independent of physical arrangement. Even if networked computers are physically placed in a linear arrangement and are joined combined to a hub, the network has a star topology, alternatively a bus topology. In this regard the visual and operational aspects of a network are distinct. Networks may be classified grounded on the process of knowledge adapted to carry the data; these include digital and analog networks. Fig2. Mesh topology Fig3. Star Topology Fig4. Ring topology What is a firewall? Fig5. firewall A firewall is a component of a computer system or network that is arranged to avoid unauthorized access where letting agent communications. It is a implement or set of tools that is configured to sanction or turn down network transmissions grounded upon a set of administers and other criteria. Firewalls can be implemented in either hardware or software, or a combination of two. Firewalls are commonly adapted to prevent unauthorized Internet users from accessing private networks joined combined to the Internet, especially intranets. All messages entering or withdrawing the intranet surpass through the firewall, which inspects each outcome and prevents those that do not find the specified protection criteria. There are several types of firewall techniques: Packet filter: Packet filtering checks each packet that is passing through the network and accepts or refuses it based on particular IP addresses that is user defined. Although difficult to configure, it is effective and mostly transparent to its users. It is vulnerable to Internet Protocol spoofing. Fig6. Packet filters This type of packet filtering pays no heed to if a packet is part of an older stream of traffic (i.e. it stores no information on connection state). Instead, it filters each packet based only on information contained in the packet itself . TCP and UDP protocols consists most communication over the net, and because TCP and UDP traffic by convention uses well known ports for some types of traffic, a stateless packet filter can differentiate between, and hence control, those types of traffic (such as web browsing, remote printing, email transmission, file transfer), untill the machines on each side of the packet filter are both using the same non-standard ports. Packet filtering firewalls work mainly on the initial three layers of the OSI reference model, which means most of the work is done in between the network and physical layers, with a little bit of peeking into the transport layer to find out source and destination port numbers. When a packet originates from the sender and filters through a firewall, the device finds matches to any of the packet filtering rules that are configured in the firewall and removes or rejects the packet accordingly. When the packet goes through the firewall, it checks the packet on a protocol/port number basis (GSS). Application gateway: Applies security mechanisms to some applications, such as FTP server. This is effective, but can degrade the performance Fig7.OSI reference model The benefit of application layer filtering is that it can understand applications and protocols and it can also detect if an unwanted protocol is sneaking through on a non-standard port or if a protocol is being used in any harmful way. An application firewall more secure and reliable as compared to packet filter firewalls as it works on all 7 layers of the OSI reference model, from the application to the physical layer. This is similar to a packet filter firewall but here it also filters information on the basis of content. In 2009/2010 the focus of the best comprehensive firewall security vendors turned to expanding the list of applications such firewalls are aware of now covering hundreds and in some cases thousands of applications which can be identified automatically. Many of these applications can not only be blocked or allowed but copied by the more advanced firewall products to allow only certain functionally enabling network security administrations to give users functionality without enabling unnecessary vulnerabilities. As a consequence these advanced versions of the Second Generation firewalls are being referred to as Next Generation and bypass the Third Generation firewall. It is expected that due to malicious communications this trend will have to continue to enable organizations to be truly secure. Third generation: stateful filters Fig8. Stateful filter Third-generation firewalls, in addition to what first- and second-generation look for, regard placement of each packet within the packet series. This technology is generally referred to as a stateful packet inspection as it maintains records of all connections going through the firewall and is able to determine whether a packet is the start of a new connection, a part of an existing connection, or is an invalid packet. Though there is still a set of defined rules in such a firewall, the state of a connection can itself be one of the criteria which trigger specific rules. This type of firewall can actually be exploited by certain Denial-of-service attacks which can fill the connections with illegitimate connections. Circuit-level gateway: Applies security mechanisms when a TCP or UDP connection is established. Once the connection has been done, packets can go between the hosts without checking further. Stateful filters Fig8. Stateful filter Third-generation firewalls, in addition to what first- and second-generation look for, regard placement of each packet within the packet series. This technology is referred to as a stateful packet inspection as it maintains records of all connections going through the firewall and is able to determine whether a packet is the start of a new connection, a part of an existing connection, or is an invalid packet. Though there is still a set of static rules in such a firewall, the state of a connection can itself be one of the criteria which trigger specific rules. This type of firewall can actually be abused by some Denial-of-service attacks which can fill the connection tables with false connections. Proxy servers Checks all messages entering and leaving the network. The proxy server hides the right network addresses. Fig9.Proxy server In computer networks, a proxy server is a server that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, asking for some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server processes the request according to its filtering rules. For example, it may filter traffic by IP address. If the request is passed by the filter, the proxy provides the resource by connecting to the relevant server and requesting the service on behalf of the client. A proxy server may alter the clients request or the servers response, and sometimes it may pass the request without contacting the specified server. In this case, it caches responses from the remote server, and sends back subsequent requests for the same content directly. Types of proxy Forward proxies Fig10.Forward proxies A forward proxy taking requests from an internal network and forwarding them to the Internet. Forward proxies are proxies where the client server names the target server to connect to. Forward proxies are able to get from a wide range of sources. The terms forward proxy and forwarding proxy are a general description of behavior (forwarding traffic) and hence ambiguous. Except for Reverse proxy, the types of proxies described on this article are more specialized sub-types of the general forward proxy concepts. Open proxies Fig11.Open proxies An open proxy forwarding requests from and to anywhere on the Internet. An open proxy is a forward proxy server that is accessible by any Internet user. Gordon Lyon estimates there are hundreds of thousands of open proxies on the Internet. An anonymous open proxy allows users to conceal their IP address while browsing the Web or using other Internet services. Reverse proxies Fig12.Reverse proxies A reverse proxy taking requests from the Internet and forwarding them to servers in an internal network. Those making requests connect to the proxy and may not be aware of the internal network. A reverse proxy is a proxy server that appears to clients to be an ordinary server. Requests are forwarded to one or more origin servers which handle the request. The response is returned as if it came directly from the proxy server. Reverse proxies are installed in the neighborhood of one or more web servers. All traffic coming from the Internet and with a destination of one of the web servers goes through the proxy server. The use of reverse originates in its counterpart forward proxy since the reverse proxy sits closer to the web server and serves only a restricted set of websites. There are several reasons for installing reverse proxy servers: Encryption / SSL acceleration: when secure web sites are created, the SSL encryption is often not done by the web server itself, but by a reverse proxy that is equipped with SSL acceleration hardware. See Secure Sockets Layer. Furthermore, a host can provide a single SSL proxy to provide SSL encryption for an arbitrary number of hosts; removing the need for a separate SSL Server Certificate for each host, with the downside that all hosts behind the SSL proxy have to share a common DNS name or IP address for SSL connections. This problem can partly be overcome by using the SubjectAltName feature of X.509 certificates. Load balancing: the reverse proxy can distribute the load to several web servers, each web server serving its own application area. In such a case, the reverse proxy may need to rewrite the URLs in each web page (translation from externally known URLs to the internal locations). Serve/cache static content: A reverse proxy can offload the web servers by caching static content like pictures and other static graphical content. Compression: the proxy server can optimize and compress the content to speed up the load time. Spoon feeding: reduces resource usage caused by slow clients on the web servers by caching the content the web server sent and slowly spoon feeding it to the client. This especially benefits dynamically generated pages. Security: the proxy server is an additional layer of defense and can protect against some OS and Web Server specific attacks. However, it does not provide any protection to attacks against the web application or service itself, which is generally considered the larger threat. Extranet Publishing: a reverse proxy server facing the Internet can be used to communicate to a firewalled server internal to an organization, providing extranet access to some functions while keeping the servers behind the firewalls. If used in this way, security measures should be considered to protect the rest of your infrastructure in case this server is compromised, as its web application is exposed to attack from the Internet. VPN A virtual private network (VPN) is a computer network that uses a public telecommunication infrastructure such as the Internet to provide remote offices or individual users with secure access to their organizations network. It aims to avoid an expensive system of owned or leased lines that can be used by only one organization. It encapsulates data transfers between two or more networked devices which are not on the same private network so as to keep the transferred data private from other devices on one or more intervening local or wide area networks. There are many different classifications, implementations, and uses for VPNs. Fig13 VPN Vulnerabilities:- Unauthorized access: This simply means that people who shouldnt use your computer services are able to connect and use them. For example, people outside your company might try to connect to your company accounting machine or to your network file server. There are various ways to avoid this attack by carefully specifying who can gain access through these services. You can prevent network access to all except the intended users. Exploitation of known weaknesses: Some programs and network services were not originally designed with strong security in mind and are inherently vulnerable to attack. The BSD remote services (rlogin, rexec, etc.) are an example. The best way to protect yourself against this type of attack is to disable any vulnerable services or find alternatives. With Open Source, it is sometimes possible to repair the weaknesses in the software. Denial of service: Denial of service attacks cause the service or program to cease functioning or prevent others from making use of the service or program. These may be performed at the network layer by sending carefully crafted and malicious datagrams that cause network connections to fail. They may also be performed at the application layer, where carefully crafted application commands are given to a program that cause it to become extremely busy or stop functioning. Preventing suspicious network traffic from reaching your hosts and preventing suspicious program commands and requests are the best ways of minimizing the risk of a denial of service attack. Its useful to know the details of the attack method, so you should educate yourself about each new attack as it gets publicized. Spoofing: This type of attack causes a host or application to mimic the actions of another. Typically the attacker pretends to be an innocent host by following IP addresses in network packets. For example, a well-documented exploit of the BSD rlogin service can use this method to mimic a TCP connection from another host by guessing TCP sequence numbers. To protect against this type of attack, verify the authenticity of datagrams and commands. Prevent datagram routing with invalid source addresses. Introduce unpredictability into connection control mechanisms, such as TCP sequence numbers and the allocation of dynamic port addresses. Eavesdropping: This is the simplest type of attack. A host is configured to listen to and capture data not belonging to it. Carefully written eavesdropping programs can take usernames and passwords from user login network connections. Broadcast networks like Ethernet are especially vulnerable to this type of attack Here are a few examples of firewalls :- Untangle Fortiguard Netnanny Websense ClearOS These firewalls can be affected by the above vulnerabilities. One way how a firewall/web filter can be bypassed is by using VPN. As studied above we can VPN to some external network and use that network. So we can bypass the firewall by doing VPN to a remote network and using its default gateway. Below are the precise steps how to setup a VPN server, Client, AD and LB configurations. Complete VPN Configuration Below is the complete procedure on how to setup VPN server and client side Note:- Windows XP and Windows 7 both have the capability to act as VPN servers VPN Server Configuration Open Network connections and follow the below :- Click next on the welcome page Select the options highlighted in the below snags :- Once you have followed the steps above you are done with the server side configuration. VPN Client Configuration Below snags show the client side configuration Once the above steps are followed the client side is also setup The work is still not over Port Forward Port needs to be forwarded from the modem/LB etc Follow the instructions below to get it rolling :- Dial in Rights on AD The final step is to give the user permissions to VPN First RDP to the AD Login Open Active Directory Find the user and go in properties Follow the snag it once the above is done :- The best firewall:- According to the first hand experience we found Untangle to be the best firewall as it is free and has a host of functions too. Below is a screenshot of the untangle dashboard:- Fig14. Untangle dashboard Conclusion:- Our aim was to explain what a firewall is and expose a few vulnerabilities in it. We have studied how a firewall works, its architecture, types of firewalls and vulnerabilities. We have thus compared the firewalls on various parameters and have concluded that Untangle is the best firewall with reference to the features and cost of it.

There are many events in this book which lead me to say how prejudiced our country was at that time. One thing that stays on my mind is the conflict between Cassie and Lillian Jean, a white girl about the same age as Cassie. During Cassie's first visit to the town of Strawberry, she accidentally bumps into Lillian Jean. It is then that Lillian Jean starts calling Cassie names (comparing Cassie's "nasty little self" with "decent white folk"), and makes her apologize. Big Ma and Charlie Simms, Lillian Jean's father, force Cassie to do so, and Cassie is also told to call her, "Miz" Lillian Jean. Cassie does not understand why this must be so, and the idea of calling someone "Miz", who is the same age as herself, hits Cassie hard.

Discuss how Stevenson presents duality in ‘Dr Jekyll and Mr Hyde Essay

In this essay I will show how Robert Louis Stevenson has presented duality in his novella ‘Dr Jekyll and Mr Hyde’. The novella is about a respectable gentleman, Dr Jekyll, and how, under the pressure of high society in Victorian England, experiments with potions to eventually come up with one that would turn him into Mr Hyde, a disreputable and evil man. Written in 1886, the novella was based around the pressure to be respectable that Robert Louis Stevenson himself felt in high society of the Victorian era. It was also influenced by scandals of the time such as Deacon Brodie. Brodie, who suffered from gambling debts, was a cabinet maker for people in the higher class. To try and pay off his debts he would break into the cabinets that he had sold and steal the valuables inside. This fits into the story of Jekyll and Hyde since Jekyll is a nice, respectable gentleman who turns into an evil, lower class man, Hyde. There was also a growing awareness of chemistry and psychology at the time the novella was written. Sigmund Freud, a famous chemist and psychologist, convinced people that duality did exist in humans – that in one person there could be both good and evil, such as in Jekyll and Hyde, who were the same person, with the help of a potion, but Jekyll was good and Hyde evil. Since the novella was written in 1886 it was targeted at Victorian people. When it was first published it sold around 40,000 copies, mainly to the higher classes of Victorian England. They would have seen it as a twist on a horror book. The Victorians were into gothic books, except that they were always set in foreign countries and in the past. ‘Dr Jekyll and Mr Hyde’ differs to these stories since it was set in London and in the then present day. In 1888, Jack the Ripper surfaced in the newspapers. This would not only have boosted the sales of Stevenson’s novella but would have been connected to it. Both the former and the latter ideas are because of the rumour that went around England at the time that Jack the Ripper was someone of upper class and respectable by day but commit atrocious murders by night, like the duality of Jekyll and Hyde. Duality appears throughout the novella, including the characters. Mr Utterson is a lawyer and good friend of Henry Jekyll. â€Å"†¦of a rugged countenance, that was never lighted by a smile; cold, scanty†¦Ã¢â‚¬  This description of Mr Utterson, from the first page, portrays him to be a grumpy man, with sharp features on his face, who doesn’t get on with anybody and who would drink on his own. However: â€Å"†¦somehow loveable.† This quote, again from the first page, shows the duality of the book since Utterson is described to be miserable and yet everybody loves him. This is enforced by the adjective ‘lovable’ since this word implies that he is pretty easy to get on with and he isn’t just liked by those who know and get on with him, instead he is loved. The quotes convey that no matter what someone’s demeanour they can still be kind and popular. This introduces the theme of duality for the reasons said above. â€Å"I let my brother go to the devil in his own way.† Being a lawyer, Mr Utterson is supposed to help others in any way he can, however, this metaphor is telling the reader that no matter how much he could do for someone, Utterson doesn’t really care about them. This portrays Robert Louis Stevenson’s idea of duality. â€Å"†¦least save his credit†¦I shall be back before midnight, when we shall send for the police.† This quote shows duality since Utterson himself said that he would ‘let his brother go to the devil in his own way’, yet here he is trying to save the reputation of one of his very good friends, Jekyll. To do this though, the good, honourable, respectable, law abiding lawyer does not send for the police as soon as he and Poole, Dr Jekyll’s butler, discover the dead body of a certain Mr Edward Hyde lying on Jekyll’s cabinet floor. Instead, he goes home for two hours to read the letters that both Dr Lanyon, another good friend of both Utterson and Jekyll, and Jekyll left for him to read on the disappearance or death of Henry Jekyll. It also shows duality in that Utterson is a lawyer, who should go to the police but doesn’t. â€Å"†¦in case of disappearance†¦read the name Gabriel John Utterson.† This quote shows duality because as Utterson finds, and reads, Jekyll’s Last Will and Testament, Utterson, to his own amazement, reads his name instead of Hyde’s. This shows duality since Utterson is down as the last good friend of Dr Henry Jekyll, who would become disreputable and a big scandal if any one were to find out what he did. Dr Lanyon is another character in the novella, and a good friend of Jekyll and Utterson. â€Å"This was a hearty, healthy, dapper, red faced gentleman with a shock of hair prematurely white.† This quote portrays Lanyon to be a friendly, upper class gentleman who has plenty to drink. However, later on in the novella, Stevenson describes Lanyon: â€Å"The rosy man had grown pale; his flesh had fallen away; he was visibly balder and older†¦Ã¢â‚¬  This quote and the latter, reveals the duality between them since in the first quote he is described as being healthy and in the second as being on his death bed. The reader would want to know what has happened in such a short time to make this change in Lanyon appear so suddenly – because he saw Hyde mix the potion, take a drink, and turn to Jekyll in front of his very own eyes – all of which is revealed in the second to last chapter ‘Dr Lanyon’s Narrative’. To get the potions to Hyde however, Jekyll had to get Lanyon to steal for him. The very idea of Jekyll wanting another respectable gentleman breaking in and stealing the potions for him and Hyde would have been a very big scandal if Lanyon was caught, and Lanyon would go from respectable gentleman to disrespectable in a few hours. Stevenson’s novella is all about Dr Jekyll and Mr Hyde. â€Å"†¦the doctor gave one of his pleasant dinners†¦Ã¢â‚¬  This shows how Jekyll is popular among the upper class, among his friends, and rich enough to hold dinners. The adverb ‘pleasant’ conveys to the audience that everyone Jekyll invited got on with each other and it reinforces the idea that Jekyll is rich since he can hold dinners and provide nice food. â€Å"†¦sat Dr Jekyll, looking deadly sick.† This quote describes Jekyll sitting in his large cabinet room, after the death of sir Danvers Carew. It reveals how Jekyll is feeling remorse for knowing, or as the reader later finds out, for being Mr Hyde – who was identified as the murderer of Carew. It portrays how Jekyll regrets his actions and wishes, to get away from the pressures of high society life in Victorian England. â€Å"†¦8th of January Utterson had dined at the doctors†¦On the 12th, and again on the 14th, the door was shut against the lawyer.† This reference conveys to the audience the duality in the novella, since four days after Utterson had seen Jekyll, and dined with him and Dr Lanyon, he was being denied entry to Jekyll’s house. This shows the duality since Jekyll was so ill that he couldn’t stand up to greet Utterson when Utterson went to see him, before being fine and healthy enough to hold a dinner party and then not allowing anyone into his house to see him all of a sudden without anybody knowing why. â€Å"†¦born in 18__ to a large fortune†¦Ã¢â‚¬  This quote portrays how Henry Jekyll recognises how he was born into a rich family. The adjectives ‘large’ and ‘fortune’ suggests he was born into a highly respected family, something that was of high importance in Victorian England. It shows how he didn’t have to work hard for the position in society that he was in, only keep up his appearances with others of his class. â€Å"†¦worst of my faults was a certain gaiety of disposition, such as made the happiness of many†¦Ã¢â‚¬  This reference shows that Jekyll felt money wasn’t everything. He felt that where it made most men content, it didn’t make him happy. It conveys to the reader how he wants to be happy, although where he is in life and society wasn’t making his wishes come true. We learn later in the novella how this wish brings him to start mixing formulas that would eventually turn him into Mr Hyde. â€Å"†¦found it hard to reconcile with my imperious desire to carry my head high†¦Ã¢â‚¬  The quote above portrays how, although Jekyll wants to be happy, he believes the only way would be one that was irreputable. However, he does not wish to lose his place in the upper class of society and he does not wish to lose his friends, both of which would happen if he did what he desired to do to become happier. This therefore is what led Jekyll to create the potion, as well as the written version of events, for Utterson to read, in ‘Henry Jekyll’s full statement of the case’ where Dr Jekyll writes his version, and the truth of what happened in the last months of his life. â€Å"Hence it came about that I concealed my pleasures†¦Ã¢â‚¬  This reveals how Jekyll had been hiding secrets since before creating the mixture that would turn him to Hyde, hiding what it was that was making him happy. The verb ‘concealed’ tells the reader that Jekyll was being very careful about his pleasures. It conveys the importance of nobody finding out about Jekyll’s secret more than if Stevenson had written the verb ‘hid’ instead. â€Å"†¦already committed to a profound duplicity of life.† This conveys one of the themes in the novella, the theme of duplicity, and how it is not only in the settings and the characters but that the characters knew about it. We know this because of the adjective ‘duplicity’ – portraying to the reader how Jekyll has two lives, however different they are. â€Å"†¦morbid sense of shame.† This quote reveals how although Jekyll wanted to be happy, he is ashamed of how his life has turned out. The alliteration of the ‘s’ sound in ‘sense’ and ‘shame’ enforces the idea, in the readers mind, that he is ashamed of being Mr Hyde, of what he has done and is still doing as Mr Hyde and that both of these irreputable things are making him happy. â€Å"†¦not truly one, but truly two.† This does not reveal duality within the story, rather in the themes of the novella. It indicates the views of Dr Jekyll – that in one man, there is both good and evil, one of the themes. Jekyll describes how good and evil are different parts of the soul, and that good conquers evil in a raging war within the soul, and that is what makes a man good. â€Å"†¦flushed as I was with hope and triumph, to venture in my new shape†¦Ã¢â‚¬  As this quote conveys, Stevenson has written about how someone can be addicted to drugs. It shows that even someone of high stature can become addicted, in this case Dr Jekyll. Jekyll is addicted to how he can do what he wants as Mr Hyde, without losing any of his own stature, rather than do the respectable things he would have to do as himself to be happy. It reveals duality in the fact that a respectable gentleman such as Jekyll can be addicted to the painful pangs and nausea the mixture makes him feel, whilst turning into Hyde. Edward Hyde is often portrayed animal-like. â€Å"†¦like a monkey jumped up from among the chemicals.† This quote makes the reader imagine a monkey like creature jumping up upon hearing Poole, Jekyll’s butler, coming towards Jekyll’s cabinet. It creates the picture of Hyde being small, dumpy, and hairy and as having very long arms, whilst showing duality since Hyde is a man not a monkey. â€Å"The other snarled aloud into a savage laugh†¦Ã¢â‚¬  In this quote the adjective ‘snarled’ gives the image of Hyde as a savage beast, again being portrayed as some sort of animal. It also conveys how Hyde is an evil person, since someone who is portrayed as being a savage cannot be any good, and this would have been the view of people in Victorian England. Stevenson has used language to paint a picture of what Hyde might look like in the readers mind. â€Å"†¦so ugly that it brought out the sweat on me like running.† This reference, again, allows the reader to imagine what Hyde looks like. It conveys how the other characters react to Hyde, that they all feel an air of deformity whenever they see him or speak to him, and that he looks so ugly, so mean that they feel uneasy around him. All of the latter three quotes show duality since Hyde is portrayed as being a small and ugly man with the impression of being deformed somewhere on his body. He is also conveyed as a mean, evil person via the descriptive language used by Stevenson. This is in contrast to Jekyll, since Jekyll is a respected gentleman and doctor of chemistry, who is regularly invited to dinner parties hosted by other well respected people in society. He is also taller, thinner and older than Hyde. All of the characters who ‘meet’ Hyde in the novella seem to act in the same way towards him. This conveys to the reader just how unlikeable Hyde is. This is important to the story because it shows how everybody thinks him an evil man. It helps show the duality between Jekyll and Hyde. However, it isn’t just the characters that show duality within Stevenson’s â€Å"Dr Jekyll and Mr Hyde†. It is also revealed in the settings – the weather and the buildings – and also in the narrative structure. â€Å"The door†¦neither bell nor knocker, was blistered and distained. Tramps slouched†¦Ã¢â‚¬  This quote portrays the quality of the door that Hyde uses to enter Dr Jekyll’s house and grounds. This is in contrast to the front of Jekyll’s house: â€Å"†¦which wore a great air of wealth and comfort†¦Ã¢â‚¬  This portrays an image of what Jekyll’s house looks like from the front – a grand house whose owner is wealthy and of a high social class. The latter quote also shows duality with Hyde’s house in Soho. â€Å"†¦showed him a dingy street†¦Ã¢â‚¬  This quote portrays what kind of area Hyde’s house is in. In the Victorian era, Soho was poverty stricken and full of prostitution, although there is no indication that Hyde was into prostitution and gambling (other than Jekyll turning into Hyde because doing respectable things did not make him happy). It shows the difference between Jekyll’s big, respectable house in a respectable of London and Hyde’s dingy flat on a polluted street in the centre of London. â€Å"An ivory faced and silvery haired woman†¦Ã¢â‚¬  This quote describes the Soho house landlady (or Hyde’s landlady). When the reader reads this they presume she is a nice friendly woman. However: â€Å"She had a smooth face, smoothed by hypocracy†¦Ã¢â‚¬  shows duality in contrast with the quote before. It shows how a nice old lady may look nice but in fact can be evil, someone who doesn’t like herself. I say evil because later in the chapter ‘The Carew Murder Case’ she is excited and delighted by the idea of Hyde being in trouble with the police. Hyde’s house in Soho is, to Utterson’s surprise, well furnished. â€Å"†¦furnished with luxury and good taste†¦Ã¢â‚¬  This conveys duality with how the house looks on the outside. With Soho being a dodgy area in Victorian England, and the street being described as ‘dingy’, the reader first imagines a poor, poverty filled room, not a luxury, well furnished house. London is also shown in a dual nature. â€Å"†¦down a by street in a busy quarter of London. The street was small and what is called quiet.† This quote shows duality in how although a street is in a busy area of London, off a busy main street; it is actually very quiet (it would be expected to be busy if it’s off a main street). Stevenson has even included duality in the weather. â€Å"†¦cool and a little damp, and full with premature twilight,†¦still bright with sunset.† This quote conveys duality to the reader since Jekyll’s courtyard is described at the beginning of the quote – that it is cold and looks as though it is around the time frame of dusk. However, the later half of the quote explains, it is in fact still sunny (nearing sunset) and so in theory Jekyll’s courtyard should be quite light. â€Å"A fog rolled over the city†¦ early part of the night was cloudless.† This reveals duality because it shows how the night was cloudless, until the fog came in. the adjective ‘rolled’ gives the impression that the fog came swiftly, rather than slowly. â€Å"About nine in the morning†¦ number of degrees and hues of twilight†¦ dark like the back end of evening†¦Ã¢â‚¬  This quote conveys to the reader that whatever time of day it is in Soho, it still looks like it’s dark, like it is night. This quote shows the duality of the weather by giving the time of day and describing what it looked like. The fog described is more likely to be smog from the factories, since the novella is set in the Victorian times. However, it does cast an eerie effect on the image conjured in the readers mind, would have made them think something sinister was about to happen. There are many locked doors in Stevenson’s novella. This symbolises how secretive the story is, Utterson hypothetically being stopped solving the mystery of Jekyll and Hyde, by doors not able to be opened until another section of the mystery is found, and the actual looked doors that Jekyll shuts himself up behind. The narrative structure also shows duality since in the first seven chapters the narrative is third person. â€Å"†¦resumed the lawyer.† This shows the third person narrative structure of ‘The Last Night’. However, the last two chapters are written in first person, ‘Dr Lanyon’s Narrative’ is written by Lanyon from his point of view and tells of what he knows about Jekyll and Hyde, and explains the cause of his death. The last chapter is also in first person, however this is from the perspective of Dr Jekyll himself, who explains everything that had happened. â€Å"I rose from my place†¦Ã¢â‚¬  These show duality because the first seven chapters, although written in third person, are all about Utterson and what he does to try and unravel the mystery between Jekyll and Hyde. They also show Utterson’s thoughts and feelings. The chapters are all arranged to follow what happens to Utterson and the titles are all to do with what happens within the chapter itself (and give a clue to what the chapter is about). The last two are in the order they are because that way Lanyon doesn’t repeat what the reader knows from reading Jekyll’s chapter, if they were the other way around. In this essay I have shown how Robert Louis Stevenson has presented the theme of duality in his novella ‘Dr Jekyll and Mr Hyde’. I have achieved this by analysing the language of the text that describes the characters, weather, buildings and the narrative structure.
