Drug Policy :: essays research papers

Drug Policy Colloquium Reflection   Ã‚  Ã‚  Ã‚  Ã‚  The war on drugs and the violence that comes with it has always brought around a hot debate about drug legalization. The amount of violence that is associated with drugs is a result from harsher drug laws and prohibition.   Ã‚  Ã‚  Ã‚  Ã‚  The business of buying and selling drugs comes with high transactions costs. The dealer cannot risk being caught or scammed so he buys a gun to defend himself from the police and other dealers. The buyer of the drugs does not to be killed for his money if the dealer gets greedy so he buys a gun for himself. Now we have two people that if it came down to it, would kill for their crack rocks. Also, if a buyer got a bad crack rock or got less than he paid for, he cannot go the police or file a complaint. He must take matters into his own hands resulting in violence. If drugs were legalized, they would be safer in the sense that the crack-head that needs his daily crack rock would not have to deal directly with dangerous drug dealers and criminals and risk getting shot for his money. Instead, he can go down to the local â€Å"drug store† and get his drugs safely.   Ã‚  Ã‚  Ã‚  Ã‚  Drugs will even become safer for those who are willing to use them. Government regulations on drug quality will make the drugs more pure, and potent, taking the harmful additives that some drug makers put in. Like cigarettes, warnings would probably be posted on drug packages stating â€Å"The use of crack may be harmful to your health.† As well as on windows of the stores that sells the drugs. An age limit to buy drugs would probably be 21. Clean, sterile needles would also be provided to heroin users and stop the spread of diseases such as AIDS from contaminated and dirty needles.   Ã‚  Ã‚  Ã‚  Ã‚  I think that if drugs were legalized, use of legal drugs would tend to rise because it would be easier to obtain them and it may encourage people to try them out. However, the increase would only be for a short time period. In the long run, drug use would decrease because all the users that are using more drugs because they are easier to get would overdose and kill themselves and set an example for other people thinking about trying drugs. Another reason why drug use would decrease is that the reason why some people use drugs is because they are illegal.

The Fate of The Universe Revealed

The Fate of The Universe Revealed Free Online Research Papers Abstract By introducing virtual 4th dimension to represent time in similar manner like 3 dimensions of space which can be measure in terms of length, the attempt is made to explain how velocity of the object in â€Å"Special Theory of Relativity† causes time dilation and how matter affects time in case of â€Å"General Theory of Relativity†. Same concept has been used to solve the â€Å"Galaxy Rotation Curve† problem and pioneer anomaly without need of any dark matter. Finally, it is shown that, increase in time affects gravity giving new definition to gravity based on which explosion of black hole and evolution of Universe is predicted. Keywords: Galaxy Rotation Curve, Dark Matter, Special and General Theory of Relativity. Introduction Our Universe is made of 3 dimensional space and one dimensional time (atleast these are the dimensions which are directly affecting to us in our day to day life and are not hidden like those remaining 7 dimensions in case of string theory). As per special and general theory of relativity, these 3 dimensional space and time are not two separate things, but are closely connected to each other. Hence, instead of measuring time in terms of unit of second, by introducing virtual 4th dimension, we can represent time in terms of measuring unit meter such that one second equal to 3*108 meter. Time Dilation in Special Theory of Relativity In following figure, the 3 dimensional space is considered as 2 dimensional sheet moving in remaining vertical virtual dimension at the speed of light, (c= 3 * 108 m) for mass less (energy) particles like photons. In real Universe, the vertical dimension shown in figure is not as like dimensions of the space having length, but it is an imaginary dimension. Here, for simplicity, it is assumed that the vertical dimension representing time is similar to dimensions of space having length as measuring quantity so that 1 second in vertical dimension is equivalent to 3* 108 m. In other words, 3 Dimensional Space is moving in 4th Dimension at the speed equal to speed of light for mass less particles like photon. Figure – 1.0 The above concept very well explains why particles like photons can travel at speed of light? It is a mass less particle which do not affect space-time geometry. Also, from figure it is seen that, for photon which is travelling at the speed of the light, its time from the frame of reference of the stationary object should be equal to zero i.e vertical distance measured in above figure should be zero. In other words, photon or energy particles should entirely live only in 3 Dimensional space. For the object having velocity less than the speed of light, the vertical distance or time can be calculated as shown in following figure. Figure – 2.0 In above figure, when the object is at stationary (V=0), the vertical dimension will always measure the distance equal to 3 * 108 m in 1 second. But, if the same object travels at velocity ‘V’, then, in one second, the vertical distance will measure [c*Sqrt{1-(V2/c2)}] m, because, the path of the object no longer remain perpendicular to our 2 Dimensional sheet but remains in inclined direction as shown in figure -2. Therefore, time of the moving object will always remain less than time in reference frame of stationary object or time is slowed down with increase in velocity ‘V of the object which is nothing but â€Å"Time Dilation† phenomenon in â€Å"Special Theory of Relativity†. Also, for moving object, time get slow down and not for the stationary object, hence, twin paradox will never happen. It is something like every object (moving as well as stationary) always remains attached with fixed or absolute frame of reference in their frame of referen ce. It means, the moving as well as stationary object in their respective frame of reference will always measure one second equal to 3* 108m in above figure. For stationary object, time and space never mixed with each other or remains as separate entities, while for moving object, its velocity V in space affects its time or vertical distance measured in virtual dimension. Time Dilation in General Theory of Relativity As per General Theory of Relativity, matter bends space-time making curvature of space-time around it giving effect of gravity and this curvature depends upon quantity of matter. More matter, more will be curvature of space-time. This concept usually demonstrated by scientists as the heavy object kept in middle of 2 dimensional rubber sheet representing fabric of 3 dimensional space which bends the rubber sheet due to its weight. When another light object is moved from edge of rubber sheet towards the heavy object, it got trapped in curvature (gravity effect) made by heavy object and follow inward spiral trajectory around this heavy object such that its velocity increases with decrease in distance from the heavy object. Finally, it collapsed into heavy object. Thus, in this demonstration, curvature of rubber sheet due to presence of heavy object very well explains gravity effect according to General Theory of Relativity. But, there is one hidden thing in above demonstration that is, in order to produce curvature effect on rubber sheet due to weight of heavy object, it requires additional force in remaining 3rd dimension (perpendicular to 2 dimensional rubber sheet) which is nothing but gravitational force produced by the Earth. For example, if same demonstration is done on the moon, the curvature produced by heavy object will become less than that on the Earth because gravitational strength of the Earth is six times greater than the moon. Now, Einstein is on right track with respect to his General Theory of Relativity which has been already confirmed through number of experiments like bending of light, mercury perihelion, gravitational lensing etc. It suggests that in order to produce effect of curvature of space-time, matter must have to produce force in the vertical virtual dimension so that this force causes the matter to move in opposite direction of flow of time. In other words, the object due to presence of its matter always moves in opposite direction wi th respect to direction of flow of time. It can be explained in the following figure: Figure – 3.0 From above, it is clear that presence of matter bends space-time slowing down time such that time near surface of the object is always less than away from it. But as already told, the vertical dimension is a virtual dimension representing time for our sake of simplicity, in real universe, instead of bending of space in time or virtual vertical dimension, it remains as flat 2 dimensional sheet such that its density become higher near the surface of the object which decreases as moving away from the object. Or space-time is not empty but filled with medium having its own density representing flat space-time which can be called as vacuum density. Thus, presence of matter causes increase in vacuum density near the object which decreases while going away from the object and finally become constant to represent flat space-time. But, if gravitational constant, G is really a constant, then curvature of space-time in above figure should not changed with increase in time difference, ?T because of increase in time itself. This can be achieved by keeping restriction on gravitational strength (acceleration) due to Gravitational Constant, G up to specified region such that beyond this region effect of G on gravitational strength become very negligible and it entirely depends upon increase in time i.e. changes in curvature of space-time is more beyond this region. The equation for gravitational strength can be written as: g = (G*M/r2)*{1+ (3P/?c2)} f(T) = a f(T) (1) -Ve sign indicates that spreading of curvature of space-time radially out. In other words, the force due to f(T) acts like repulsive force or opposite to attractive gravitational force. Where, g = Gravitational strength or acceleration, G = Gravitational constant = 6.67*10-11 m3/(Kg*Sec2); M = Mass of the object creating gravitational field, r= distance from the center of the object, and f(T) = Function of Time which acts opposite to gravitational strength. From above eq., for f(T) very less than a, G dominates the gravitational strength and as a becomes very less than f(T) because of inverse square relationship with r, g must be expressed in terms of f(T). Note that value of G always remains constant and changes in curvature of space-time is governed by f(T) beyond the region from where effect of G becomes negligible while effect of increase in time dominates beyond this region. The above analysis can be well illustrated in following figure; Figure – 4.0 From above figure, the region for which value of af(T) the change in the value of g is very small while for a

Civil Wars Wet Plate Collodion Photography

Civil War's Wet Plate Collodion Photography The wet plate collodion process was a manner of taking photographs which used panes of glass, coated with a chemical solution, as the negative. It was the method of photography in use at the time of the Civil War, and it was a fairly complicated procedure. The wet plate method was invented by Frederick Scott Archer, an amateur photographer in Britain, in 1851. Frustrated by the difficult photography technology of the time, a method known as calotype, Scott Archer sought to develop a simplified process for preparing a photographic negative. His discovery was the wet plate method, which was generally known as the â€Å"collodion process.† The word collodion refers to the syrupy chemical mixture which was used to coat the glass plate. Numerous Steps Were Required The wet plate process required considerable skill. The required steps: A glass sheet was coated with chemicals, known as collodion.The coated plate was immersed in a bath of silver nitrate, which made it sensitive to light.The wet glass, which would be the negative used in the camera, was then placed in a light-proof box.The negative, in its special light-proof holder, would be placed inside the camera.A panel in the light-proof holder, known as the dark slide, along with the lens cap of the camera, would be removed for several seconds, thereby taking the photograph.The â€Å"dark slide† of the light-proof box was replaced, sealing the negative up in darkness again.The glass negative was then taken to the darkroom and developed in chemicals and â€Å"fixed,† making the negative image on it permanent. (For a photographer working in the field during the Civil War, the darkroom would be an improvised space in a horse-drawn wagon.)The negative could be coated with a varnish to ensure the permanence of the image.Prints would later be generated from the glass negative. The Wet Plate Collodion Process Had Serious Drawbacks The steps involved in the wet plate process, and the considerable skill required, imposed obvious limitations. Photographs taken with the wet plate process, from the 1850s through the late 1800s, were almost always taken by professional photographers in a studio setting. Even photographs taken in the field during the Civil War, or later during expeditions to the West, required the photographer to travel with a wagon full of equipment. Perhaps the first war photographer was a British artist, Roger Fenton, who managed to transport cumbersome photographic equipment to the battlefront of the Crimean War. Fenton had mastered the wet plate method of photography soon after it became available and put it into practice shooting landscapes of the British midlands. Fenton took a trip to Russia in 1852 and took photographs. His travels proved that the latest photographic method could be utilized outside of a studio. However, traveling with the equipment and the necessary chemicals to develop the images would present a formidable challenge. Traveling to the Crimean War with his photographic wagon was difficult, yet Fenton managed to shoot impressive photographs. His images, while praised by art critics upon his return to England, were a commercial failure. Roger Fentons photographic van used in the Crimean War, with his assistant posing on its bench. Library of Congress While Fenton had transported his ungainly equipment to the front, he purposely avoided photographing the ravages of war. He would have had many opportunities  to depict wounded or dead soldiers. But he probably assumed his intended  audience in Britain did not want to see such things. He sought to portray a more glorious side of the conflict, and tended to photograph officers in their dress uniforms. In fairness to Fenton, the wet plate process made it impossible to photograph action on the battlefield. The process allowed for a shorter exposure time than previous photographic methods, yet it still required the shutter to be open for several seconds. For that reason there could not be any action photography with wet plate photography, as any action would blur. There are no combat photographs from the Civil War, as people in the photographs had to hold a pose for the length of the exposure. And for photographers working in battlefield or camp conditions, there were great obstacles. It was difficult to travel with the chemicals required for preparing and developing the negatives. And the glass panes used as negatives were fragile and carrying them in horse-drawn wagons presented a whole set of difficulties. Generally speaking, a photographer working in the field, such as Alexander Gardner when he shot the carnage at Antietam, would have an assistant along who mixed the chemicals. While the assistant was in the wagon preparing the glass plate, the photographer could set up the camera on its heavy tripod and compose the shot. Even with an assistant helping, each photograph taken during the Civil War would have required about ten minutes of preparation and developing. And once a photograph was taken and the negative was fixed, there was always a problem of a negative cracking. A famous photograph of Abraham Lincoln by Alexander Gardner shows damage from a crack in the glass negative, and other photographs of the same period show similar flaws. By the 1880s a dry negative method began to be available to photographers. Those negatives could be purchased ready to be used, and did not require the complicated process of preparing the collodion as required in the wet plate process.

International business strategies Essay Example | Topics and Well Written Essays - 3000 words

International business strategies - Essay Example Either the author of the statement is unbelievably naive, or it is merely an attempt to be provocative with didactic intent. Take the classic example of Mark & Spencer plc, which began in 1894 as a single high street store owned by two men, selling all items said to be costing no more than a penny to the customer. Over the years it conquered the retail sector with branches in prime locations all over the UK, and in overseas territories, totalling more than 885 stores. Not only did Marks & Spencer evolve into the giant corporation which it is today by reading the changes in the environment well, and meeting the growing needs of more and more affluent consumers, it also influenced the shopping habits of its clients. The business firm is not a faceless entity; at best, it can be an icon of social and economic progress, and at worst become vanquished by its inability to read the environment, Woolworths and MFI being two recent examples of such failure. How the environment impacts on the fortunes of the business firm is nowhere more evident than in the collapse of many business enterprises including financial institutions (banks) in the current worldwide economic downturn. Even starker is the effect of continuing bad weather either in the form of floods or snow on the viability of a whole range of firms in the UK. Had the environment represented by the UK government not provided a lifeline to some of the major banks in the form of taxpayer subsidies, or buy-outs, they would not have survived. Different political ideologies at different times affect the business enterprise in different ways. The collapse of communism and the breaking down of the Berlin wall in 1989, coupled with the Internet phenomenon resulted in the abolition of legislation preventing global communication and industrialisation. Since then there has been a plethora of international mergers, acquisitions

EUROPEAN UNION EQUALITY POLICIES AND WORKPLACE LEGISLATION Essay

EUROPEAN UNION EQUALITY POLICIES AND WORKPLACE LEGISLATION - Essay Example The legislation also advocate for the provisions that ensure that the disabled people in the society are able to work comfortably. This essay shall discuss the equality policies and workplace legislations that cover gender, age, religion and belief, race, and ethnicity. The European Union has formulated policies that advocate for gender equality in many angles. They ensure and promote the existence of equity between men and women, the promote application of gender mainstreaming and facilitate exploration of transgender issues. The policies ensure that the European Union observes gender equality in all the activities at the workplace. The legislations through the Treaty of Rome came up with a principle that ensure that each member state shall give equal pay for men women for equal work (Allen QC & Crasnow, 2001). This principle advocates for equality between men and women and concentrates in the equality at the workplace than in the society. Among all the inequalities in the workplace, the European Union takes more focus to address the issue of gender inequality. The European Union has so far launched a committee that advocates for women rights in its member states. It then established a commission on equal opportunities for all gender to support th e activities carried out by the advisory that handles issues on the availability of equal opportunities between men and women. To sum all these efforts up the European Union has a Commissioner that issues an annual report on gender equality (Carver & Mottier, 1998). The European union refers to equality between men and women when dealing with issues of gender equality rather than women rights since the latter appears as one sided which shows one kind of gender is given dominance. Apart from the provision of equal pay for equal work of an equal value for all gender the European Union has a directive that ensures equal treatment for all gender in matters concerning access to training and employment. This clause also

Does globalization threaten cultural diversity Essay - 2

Does globalization threaten cultural diversity - Essay Example Indeed, inter-dependency of resources, including economic pressures, labor, cultural competency, market compulsion etc. are important imperatives that give thrust to the process of globalization. People move from one country to another to exploit opportunities for personal and professional growth which has resulted in multicultural societies. Big businesses look for new opportunities across globe to expand their business and revenues. This necessitates understanding of people and their culture so that they can interact with empathy and develop mutual respect for peaceful existence. Thus, globalization helps people become more understanding of other cultures and promotes acculturation to become part of mainstream society of the host country. Julia Galeota’s main argument is that globalization is actually promoting American hegemony and directly and indirectly is responsible for other cultures to lose their identity under the powerful influence of American values. The economic and military power of America has been an important ingredient that has significantly impacted global market and spread American culture across national borders. She claims that globalization has brought in more multinational companies in the developing and under developed countries and popularized their products. McDonald’s burgers and Coca Cola are easily available across the globe and people are increasingly learning English to adapt to American way of life. It contends that technology and media have been vital propellants that have helped America’s monopoly in global environment which has motivated people to adopt American ways, including goods and services, which has threatened the survival of their own unique culture and values. Phillipe Legraine argues more rationally and looks at globalization with greater insight and wider perspective of development. He rightly asserts that when American businesses expand across globe, they localize their products to suit the requirements of people. Thus, MTV in Saudi Arabia and China does not focus on the latest hip hop or rock music of America but adapts itself and showcases local music. They could experiment and mix but primarily they cater to the local demands. In America also, the cultural diversity is emphasized because of the changing socio-economic and political compulsions. The world is changing fast and inter-dependency of resources has become a reality. Cultural diversity not only provides firms and individuals with more leverage to compete but the nations also benefit because of the unique talents that diversity brings with it. Globalization has given a big boost to industrialization and development and created platform for equity and equal opportunit ies in all spheres of life and therefore has promoted the causes of cultural diversity. Answer 3 Julia Galeota’s assertion that globalization has threatened cultural diversity to certain extent supports Samuel Huntington’s view that the dominating source of conflicts would be cultural (Huntington, 1993). Huntington believes that civilization, as highest cultural grouping of people where people gain different identities within the broader precinct of their national identities, can also become main issue of conflict in the modern world. For example, Galeota says that China, Cube and
