How War Is Necessary Essay Example for Free

How War Is Necessary Essay Mr.Weirzbowski-English 10 War has been with mankind for many millenniums. The reasons for wars in mankind’s history have all been various, however one big reason for war is that countries want to grow bigger, by taking over one another. Throughout history, rulers would not be satisfied with the amount of land that they had or wanted to spread their beliefs around the world. So, they did it by trying to take over others. However, some didn’t want to give up their land or change, so they fought. Fighting these wars are, however, necessary no matter what people believe. This is because fighting them and winning will stop them from controlling others. Some wars that stopped countries from controlling others are the second world war, the war in Vietnam, and the Revolutionary war. However, there are claims that the Vietnam war could’ve been avoided, but there would’ve been consequences for going to war. War is necessary because it’s a way to try to stop countries from dominating over others and controlling them. There are many ways that war has stopped countries from controlling one another. Firstly, the Vietnamese war was necessary because, the war would’ve stopped the spreading of communism to neighboring asian countries, also known as the â€Å"domino theory†. The idea of communism started with the election of Ho Chi Minh in North Vietnam. Kennedy wasn’t concerned with Vietnam until Lyndon B Johnson called Ngo Dinh Diem the â€Å"Wi nston Churchill of Asia† because, Diem was the only one trying to resist the communists and Johnson promised to help him. Noam Chomsky, a US philosopher, stated that if a country better its economy due to communism, neighboring countries would try to improve their economy using communism, as seen when China influenced North Vietnam. Had communism been successfully spread to South Vietnam, then Thailand, Malaysia, Indonesia, etc. Also, other countries would’ve lost faith in the US for not protecting S.Vietnam in their time of need. This shows that the US needed to fight this war to stop the communistic ideals from spreading to countries and to keep the confidence of other countries around the world, so that they could help the US when the US needs them. The second world war as necessary  because, it showed how the world responds to a fascist ruler controlling a major country, trying to claim the world. It also showed how the US would react when attacked by another major country. Hitler want to create a â€Å"master race†, which was blonde-haired, blue-eyed people. So when he came into power, he had convinced the german people that jewish people were less than humans and should be treated as such. Thus he started taking over various countries in Europe and started killing jewish people to start his plan. While that was happening, the US was maintaining neutrality and supplying Britain, Russia, and China with weapons until the japanese attacked pearl harbor on December 1941. The US then declared war on Japan and fought in the Pacific theater until August 15th, 1945. Had the axis powers won World War II, North America and South America would be surrounded by dictators ready to destroy democracy and take over the world. Also, H itler’s plan would’ve probably been completed and the world would’ve been comprised of blonde, blue-eyed people. However, the war told us that when we are concerned with individualism, we become selfish and corrupted or under the influence of corrupted selfish nations. This war was needed because, when one tries to dominate and take over another country, we become blinded and end falling. We need teamwork to stay strong in the world. Finally, the Revolutionary War was necessary because, it allowed rights normally granted by the king, to be for every single individual. It also sparked other revolutions, along with stopping Britian from controlling the colonies. When the French Indian War concluded, King George III made the Proclamation of 1763, which stated that no colonists may settle west of the Appalachian and anyone other than Indians there had to move from the area. The Boston Massacre also brought them closer to the revolution, because British soldiers killed 5 civilians for calling them names. The Stamp Act of 1765, Townshend Act of 1767, and the Tea Act of 1773, were all attempt of Britian to try and control the colonies in North America. However after the war, the Declaration of Independence was signed and Britian let the colonies rule themselves. With this newfound freedom, the colonists were allowed to trade with anyone they wanted, colonize past the Appalachian Mountains, set up a new government and th e British moved out of the colonies. Had the colonists lost the war, the US would probably still be under British rule to this day. Even with all this evidence that war is necessary, people still see war as a terrible thing. Going back to the Vietnam War, the Vietnamese War could’ve been avoided because the US could’ve stayed neutral and let the problem in Vietnam blow over, instead of sacrificing 50,000 men. The war would’ve been avoided and Vietnam would’ve became a communist country along with possibly, part of Asia. Robert McNamara, defense chief under John F Kennedy and Lyndon B Johnson, says that he doubted Vietnam would let China or Russia use them as a base, but that’s the US had feared at the time. The US had feared that China or Russia would use them as a base they could use to control more parts of Asia. The Vietnamese could’ve probably fought the war themselves and probably resisted the communistic ways of China and/or Russia. The belief about if war is needed in the world or not cuts both ways. Either that it helps bring everlasting peace in the world closer or it’s useless and all it does is kill off innocent people. War is a big thing that stops countries from trying to gain total global domination or keeping them at bay until they give up. Until that happens, there will be allies who will attack at a moments notice when a country is trying to bite off more than it can chew.There are so many more examples of how war is necessary in the world that this would be a lot longer than it is already. The concept of war may seem bad, but in the end, it’s all worth it.

Adaptation to Climate Change

Adaptation to Climate Change ADAPTATION TO CLIMATE CHANGE; AN ISSUE THAT MUST NOT BE OVERLOOKED There are many compelling questions one can ask about how climate science experts and economic experts interpret the change in climate and man’s contribution to it. To argue that our earth is not warming is futile; nonetheless, the risk of trying to prevent it is very high. It is only useful if we try to adapt. In the field of climate change, scientists denounce non-science experts claiming that these are technical questions for those who understand the theories and concepts. The controversy over whether global warming exists or not, is undoubtedly, a scientific question. However, deciding whether we should intervene, and if so, what actions to embrace is clearly not a scientific question. It is an economic question, which puts us firmly in the realm of economic experts. For any continuing event, there are five theory responses: maximizing, inverting, preventing, adapting and ignoring. Supposing we do not want to maximize or ignore global warming, the three applicable options are reversing, prevention (known as â€Å"mitigation† in the climate change idiom) or adaptation. Right up until the present day, the favoured option has been prevention. For a period of twenty-five years, public servants have debated only this response. Margaret Thatchers speech to the UN assembly (in 1989) throws light on the beginning of this approach. Later came Al Gore and Kyoto with the Stern Review adding to the list. Currently, David Cameron and Edward Miliband debate about whether or not climate change is a national security threat and which party is best placed to prevent this threat. There are good scientific reasons to believe that prevention (or even inverting) is a realistic option. Since the `90s there have been tremendous breakthroughs with our ability to reduce chlorofluorocarbons. Despite this, there are those who believe that the past twenty-five years have brainwashed us into believing that our potential and ability to prevent global warming by reducing Carbon emissions is much less compared to some Sulphur emissions and other pollutants. These years of framing tremendous exorbitant prevention schemes only took some few degrees centigrade off global warming, in comparison with the rise of three to four degrees. This puts the minimum price of such vanity at 5 per cent of Gross Domestic Product each year, with some models recommending that the definite cost is realistically more than 20 per cent. Scientific inclined people reply by saying we must increase our attempt to prevent global warming from advancing. However, China and India and America will disagree and in economically desolate Britain there are no chances requesting for more. Considering prevention were realistic, policy analysis recommends it would be dreadful an idea to consider. At the moment, according to government criteria in the UK, there is difficulty in trying to get access to a global warming mitigation scheme that matches cost with benefits. As an example, the rediscovery of the strategy for the renewal of energy having a twenty-year cost of fifty-seven billion pounds to seventy billion pounds but only benefits around four billion pounds to five billion pounds. The problem is so worse that couple of years back the guidance for the ministerial sign-off of policy impact assessments amended the strategy so that ministers no longer proclaim that their assertion that benefits will exceed costs. At the present moment, they sign to acknowledge they solely assume that benefits â€Å"justify† costs. The few analysis that found more positive net profits, such as the Climate Change Act of 2008, reckoned a global consensus that has not been implemented. On that note, it is absurd to recommend that the UK’s doing ten times more to prevent warming proceedings could perhaps be an outstanding scheme, even though it will be possible to work. The economics of preventing global warming has simply not been up to the task. Prior to the famous Stern Review, economic experts observing the sector thought that adapting to the change in climate patterns should be the pivotal strategy. What â€Å"adaptation† will suggest in a practical way is that we cut the risk of spending too much money, and the program will be less complicated. There are some UK Green schemes that influence the public to use extravagant energy and make them pay out incompetent immense sum of capital to cater for insulation. These Green systems also tax their traveling in ways that force them to execute reduced trade and craft which does not only hamper the growth, but also make adaptation very hard and unyielding. In the year 2012 the UK authority acquired forty-five billion pounds from fuel taxes, which corresponds to 2.9% GDP. While UK authorities evaluate green schemes will increase medium-scaled vocation invoice by thirty-eight per cent over the next sixteen years. On the contrary, the most outstanding project is by instigatin g GDP to allow the folks to be more prone to behaving in ways that are friendly to their habitat Moreover, the public should not misuse their wealth, on mitigation attempts while fragmenting capital for adaptation. If the UK authorities do not have enough funds and they should opt between money for energy and money for flooding protection, it must be considered a walkover. There is the need to investigate several ways to adapt to the warming of our globe with likely brutal climate. These strategies should change the methods of supporting our rivers by building flood defence systems, developing of crops that can be tolerant to drought and using water sources that are scarce in a more efficient manner. Adaptation would not be inexpensive or straightforward. However, it will be more attainable than prevention and will cost so much less. Additionally, adaptation is highly safer than prevention on two significant techniques. Firstly, we do expect that global warming will not occur as we presume. Ten years earlier, scientists studying climate patterns have scuffled to explain that the temperature has not sprung in view of the late 80s. They persist it does not make any discrepancy to their indelible tale about whether warming advancement exists, and what their consequential effects are. Moreover, perchance, it could be right. Nevertheless it makes a change to policy assessment.   If, in 1997, it was clear that abstaining from mitigation of climate patterns could not cause any rise in temperatures, there should have been a concern to adjust the way we assess our schemes. Virtually no scheme which has no effect within three to five years is a good one to start, by virtue of how we discount our future. Secondly, adaptation is much safer considering we only know nearly insufficient facts about prevention strategies and may suffer a great loss if they do not function, or they might develop delinquent long duration response. When we adapt only when there is a need, there is a reduction in waste of time and capital that is crucial to sustainable development.   At the point of finality, adaptations make us prosperous and have richer tastes. It seems plausible that we can devise means that can stop global warming from getting out of hand. However, we have wasted twenty-five years in trying to prevent warming of our globe, and have merely scraped the plain. In that initiative, we have lost untold large sums of money and are planning to waste even more. We do not have to disbelief the real existence of climate change to reject the notion that adaptation is a not a good tactic. Our method of prevention has perished, adaptation is the key.

The mesh generation

The mesh generation Describe general methods (structured, unstructured, hybrid, adaptive, etc.) and discuss their key features and applications A key step of the finite element method for numerical computation is mesh generation. One is given a domain (such as a polygon or polyhedron; more realistic versions of the problem allow curved domain boundaries) and must partition it into simple â€Å"elements† meeting in well-defined ways. There should be few elements, but some portions of the domain may need small elements so that the computation is more accurate there. All elements should be â€Å"well shaped† (which means different things in different situations, but generally involves bounds on the angles or aspect ratio of the elements). One distinguishes â€Å"structured† and â€Å"unstructured† meshes by the way the elements meet; a structured mesh is one in which the elements have the topology of a regular grid. Structured meshes are typically easier to compute with (saving a constant factor in runtime) but may require more elements or worse-shaped elements. Unstructured meshes are often computed using quadtrees, or by Delaunay triangulation of point sets; however there are quite varied approaches for selecting the points to be triangulated The simplest algorithms directly compute nodal placement from some given function. These algorithms are referred to as algebraic algorithms. Many of the algorithms for the generation of structured meshes are descendents of â€Å"numerical grid generation† algorithms, in which a differential equation is solved to determine the nodal placement of the grid. In many cases, the system solved is an elliptic system, so these methods are often referred to as elliptic methods. It is difficult make general statements about unstructured mesh generation algorithms because the most prominent methods are very different in nature. The most popular family of algorithms is those based upon Delaunay triangulation, but other methods, such as quadtree/octree approaches are also used. Delaunay Methods Many of the commonly used unstructured mesh generation techniques are based upon the properties of the Delaunay triangulation and its dual, the Voronoi diagram. Given a set of points in a plane, a Delaunay triangulation of these points is the set of triangles such that no point is inside the circumcircle of a triangle. The triangulation is unique if no three points are on the same line and no four points are on the same circle. A similar definition holds for higher dimensions, with tetrahedral replacing triangles in 3D. Quadtree/Octree Methods Mesh adaptation, often referred to as Adaptive Mesh Refinement (AMR), refers to the modification of an existing mesh so as to accurately capture flow features. Generally, the goal of these modifications is to improve resolution of flow features without excessive increase in computational effort. We shall discuss in brief on some of the concepts important in mesh adaptation. Mesh adaptation strategies can usually be classified as one of three general types: r-refinement, h-refinement, or p-refinement. Combinations of these are also possible, for example hp-refinement and hr-refinement. We summarise these types of refinement below. r-refinement is the modification of mesh resolution without changing the number of nodes or cells present in a mesh or the connectivity of a mesh. The increase in resolution is made by moving the grid points into regions of activity, which results in a greater clustering of points in those regions. The movement of the nodes can be controlled in various ways. On common technique is to treat the mesh as if it is an elastic solid and solve a system equations (suject to some forcing) that deforms the original mesh. Care must be taken, however, that no problems due to excessive grid skewness arise. h-refinement is the modification of mesh resolution by changing the mesh connectivity. Depending upon the technique used, this may not result in a change in the overall number of grid cells or grid points. The simplest strategy for this type of refinement subdivides cells, while more complex procedures may insert or remove nodes (or cells) to change the overall mesh topology. In the subdivision case, every â€Å"parent cell† is divided into â€Å"child cells†. The choice of which cells are to be divided is addressed below. For every parent cell, a new point is added on each face. For 2-D quadrilaterals, a new point is added at the cell centroid also. On joining these points, we get 4 new â€Å"child cells†. Thus, every quad parent gives rise to four new offsprings. The advantage of such a procedure is that the overall mesh topology remains the same (with the child cells taking the place of the parent cell in the connectivity arrangement). The subdivision process is similar for a triangular parent cell, as shown below. It is easy to see that the subdivision process increases both the number of points and the number of cells A very popular tool in Finite Element Modelling (FEM) rather than in Finite Volume Modelling (FVM), it achieves increased resolution by increasing the order of accuracy of the polynomial in each element (or cell). In AMR, the selction of â€Å"parent cells† to be divided is made on the basis of regions where there is appreciable flow activity. It is well known that in compressible flows, the major features would include Shocks, Boundary Layers and Shear Layers, Vortex flows, Mach Stem , Expansion fans and the like. It can also be seen that each feature has some â€Å"physical signature† that can be numerically exploited. For eg. shocks always involve a density/pressure jump and can be detected by their gradients, whereas boundary layers are always associated with rotationality and hence can be dtected using curl of velocity. In compressible flows, the velocity divergence, which is a measure of compressiblity is also a good choice for shocks and expansions. These sensing paramters which can indicate regions of flow where there are activity are referred to as ERROR INDICATORS and are very popular in AMR for CFD. Just as refinement is possible by ERROR INDICATORS as mentioned above, certain other issues also assume relevance. Error Indicators do detect regions for refinement, they do not actually tell if the resolution is good enough at any given time. In fact the issue is very severe for shocks, the smaller the cell, the higher the gradient and the indicator would keep on picking the region, unless a threshold value is provided. Further, many users make use of conservative values while refining a domain and generally end up in refining more than the essential portion of the grid, though not the complete domain. These refined regions are unneccesary and are in strictest sense, contribute to unneccesary computational effort. It is at this juncture, that reliable and resonable measure of cell error become necessary to do the process of â€Å"coarsening†, which would reduce the above-said unnecessary refinement, with a view towards generatin an â€Å"optimal mesh†. The measures are given by sensors referred to as ERROR ESTIMATORS, literature on which is in abandunce in FEM, though these are very rare in FVM. Control of the refinement and/or coarsening via the error indicators is often undertaken by using either the solution gradient or soultion curvature. Hence the refinement variable coupled with the refinement method and its limits all need to be considered when applying mesh adaptation A hybrid model contains two or more subsurface layers of hexahedral elements. Tetrahedral elements fill the interior. The transition between subsurface hexahedral and interior tetrahedral elements is made using degenerate hexahedral (pyramid) elements. High quality stress results demand high quality elements, i.e., aspect ratios and internal angles as close to 1:1 and 90 °, respectively, as possible. High quality elements are particularly important at the surface. To accommodate features within a component, the quality of elements at the surface of a hexahedral model generally suffers, e.g., they are skewed. Mating components, when node-to-node contact is desired, can also adversely affect the models element quality. Even more difficult is producing a tetrahedral model that contains high quality subsurface elements. In a hybrid model, the hexahedral elements are only affected by the surface mesh, so creating high quality elements is easy. Minimal effort is required to convert CAD data into surface grids using the automated processes of pro-surf. These surface grids are read by pro-am. The surface grid is used to extrude the subsurface hexahedral elements. The thickness of each extruded element is controlled so that high quality elements are generated. The interior is filled automatically with tetrahedral elements. The pyramid elements that make the transition are also generated automatically. A hybrid model will generally contain many more elements than an all-hexahedral model thus increasing analysis run-time. However, the time saved in the model construction phase the more labor intensive phase more than makes up for the increased run-time. Overall project time is reduced considerably. Also, as computing power increases, this â€Å"disadvantage† will eventually disappear. Hexahedral Meshing ANSYS Meshing provides multiple methods to generate a pure hex or hex dominant mesh. Depending on the model complexity, desired mesh quality and type, and how much time a user is able to spend meshing, a user has a scalable solution to generate a quick automatic hex or hex dominant mesh, or a highly controlled hex mesh for optimal solution efficiency and accuracy. Mesh Methods: Automated Sweep meshing Sweepable bodies are automatically detected and meshed with hex mesh when possible Edge increment assignment and side matching/mapping is done automatically Sweep paths found automatically for all regions/bodies in a multibody part Defined inflation is swept through connected swept bodies User can add sizing controls, mapped controls , and select source faces to modify and take control over the automated sweeping Adding/Modifying geometry slices/decomposition to the model also greatly aids in the automation of getting a pure hex mesh. Thin Solid Sweep meshing This mesh method quickly generates a hex mesh for thin solid parts that have multiple faces as source and target. Can be used in conjunction with other mesh methods User can add sizing controls, mapped controls, and select source faces to modify and take control over the automated sweeping MultiZone Sweep meshing This advanced sweeping approach uses automated topology decomposition behind the scenes to attempt to automatically create a pure hex or mostly hex mesh on complicated geometries Decomposed topology is meshed with a mapped mesh or a swept mesh if possible. A user has the option to allow for free mesh in sub-topologies that cant be mapped or swept. Supports multiple source/target selection Defined inflation is swept through connected swept bodies User can add sizing controls, mapped controls and select source faces to modify and take control over the automated meshing Hex-dominant meshing This mesh method uses an unstructured meshing approach to generate a quad dominant surface mesh and then fill it with a hex dominant mesh This approach generally gives nice hex elements on the boundary of a chunky part with a hybrid hex, prism, pyramid, test mesh internally Tetrahedral Meshing The combination of robust and automated surface, inflation and tet meshing using default physics controls to ensure a high-quality mesh suitable for the defined simulation allows for push-button meshing. Local control for sizing, matching, mapping, virtual topology, pinch and other controls provide additional flexibility, if needed. Mesh Methods: Patch conforming mesh method: Bottom-up approach (creates surface mesh, then volume mesh) Multiple triangular surface meshing algorithms are employed behind the scenes to ensure a high quality surface mesh is generated, the first time From that inflation layers can be grown using several techniques The remaining volume is meshed with a Delaunay-Advancing Front approach which combines the speed of a Delaunay approach with the smooth-transitioned mesh of an advancing front approach Throughout this meshing process are advanced size functions that maintain control over the refinement, smoothness and quality of the mesh Patch independent mesh method: Top-down approach (creates volume mesh and extracts surface mesh from boundaries) Many common problems with meshing occur from bad geometry, if the bad geometry is used as the basis to create the surface mesh, the mesh will often be bad (bad quality, connectivity, etc.) The patch independent method uses the geometry only to associate the boundary faces of the mesh to the regions of interest thereby ignoring gaps, overlaps and other issues that give other meshing tools countless problems. Inflation is done as a post step into the volume mesh. Since the volume mesh already exists, collisions and other common problems for inflation are known ahead of time. Note: For volume meshing, a tetrahedral mesh generally provides a more automatic solution with the ability to add mesh controls to improve the accuracy in critical regions. On the contrary, a hexahedral mesh generally provides a more accurate solution, but is more difficult to generate. Shell and Beam Meshing For 2-D planar (axisymmetric), shell and beam models, ANSYS Meshing provides efficient tools for quickly generating a high quality mesh to accurately simplify the physics. Mesh Methods for shell models: Default surface meshing Multiple surface meshing engines are used behind the scenes to provide a robust, automated surface mesh consisting of all quad, quad dominant or all tri surface mesh. User can add sizing controls, and mapped controls to modify and take control over the automated meshing Uniform surface meshing Orthogonal, uniform meshing algorithm that attempts to force an all quad or quad dominant surface mesh that ignores small features to provide optimum control over the edge length Describe key features of ALL existing meshing options in Ansys Mesh module and discuss their applications The meshing tools in ANSYS Workbench were designed to follow some guiding principles: Parametric: Parameters drive system Persistent: Model updates passed through system Highly-automated: Baseline simulation w/limited input Flexible: Able to add additional control w/out complicating the workflow Physics aware: Key off physics to automate modelling and simulation throughout system Adaptive architecture: Open system that can be tied to a customers process CAD neutral, meshing neutral, solver neutral, etc. By integrating best in class meshing technology into a simulation driven workflow, ANSYS Meshing provides a next generation meshing solution.

The Slavery Effect In Todays Society

The Slavery Effect In Todays Society In the eighteenth century there were an estimated six million slaves in the world. That number, large as it was, does not come close to the number of slaves in todays society. The current worldwide estimates are over twenty-seven million. Every year seventeen thousand slaves are trafficked into the United States, of that number, eighty percent are women and fifty percent of those (seven thousand) are children. Seventy percent of the females are imported for prostitution. It is astonishing how even though slavery is not seen or heard of much in todays society it still exists heavily and quietly affects our everyday life. It is extremely sad, yet, regretfully true. The history of slavery dates back to 1780 B.C. though laws have been passed in most countries that prevent, or at least lessen, slavery, it still exists today. By definition, slavery means the complete ownership and control by a master: to be sold into slavery. Slavery indicates a state of subjugation or captivity often involving burdensome and degrading labor. Slavery occurs when people -known as slaves- were placed in servitude as the property of a household or company. Slaves are deprived of their personal freedom and compelled to perform labor or services. Slaves are the properties of another person, household, company, corporation, or government and are unable to leave or have any freedom. Primarily slaves were sold amongst companies, corporations, governments, or people. The practice of exporting slaves is called slave trafficking. Slavery is currently found in many countries all over the world. In other countries, though known by another name, it is still slavery. In Canada sl aves are called servants and in Nordic countries they are called thralls. In the year 1670 the first African slave was introduced to America. The slaves of that time period were treated poorly; most were beaten with whips for the slightest infraction. Most, were simply tired, hungry or thirsty; some just too old to do the work and were brutally beaten to death. Many slaves would die of illnesses like malaria or yellow fever because of their limited immunities to these diseases. Others died from malnutrition, poor living conditions, and exhaustion; there was a very high mortality rate among slaves. To this day slaves are still exploited all over the world even though we actually do not see it or hear about it. Although in most countries in todays society traditional slavery has been abolished, it still exists in some countries and much of the slavery that exists is done so illegally. Some of the countries that have abolished slavery are the United States, Africa, many European countries, and China. Though abolished, it still exists, just using a different title. The highest percentage of slavery that is seen in todays age is child labor. Many countries have enacted child labor laws, protecting the rights of children. Typically children are not allowed to work until they reach the age of fourteen. There are children as young as four working on plantations. Most child labor laws state that only children over the age of fourteen can work between the hours of seven in the morning until nine at night and no more than forty hours per week or eight hours in one day excluding school da ys in which they can work after school until 8:00 PM. Children, prior to the age of 18 must get a work permit filled out by their school before they are allowed to work; these children must maintain at least a 2.0 grade point average in order to continue their employment. In many countries this is not the case and the childrens primary duty is work. These children do not have the chance of an education. Child labor is not the only form of slavery still in existence. Some companies maintain a policy of only enslaving adults, while others only employ children. Many children who are put into slavery end up working in clothing manufacturing plants also known as sweatshops. A sweatshop is a factory where workers make products in very poor working conditions. Child labor is also abused in harvesting cotton, fruits, and vegetables. Many slaves also work in sugar cane and coffee factories. The selling of females, as disgusting as this may sound, is still a common practice in some countries. Young women are often sold by their families for marriage, domestic uses, like cleaning and cooking, while others are sold into sex trafficking and were forced into prostitution. Many children are taken from their families to become soldiers. Countries such as Lebanon and Colombia regularly enlist young children to carry guns and become soldiers of war. Rarely is this considered a form of slavery, yet by definition, it is. As you can see there are many types of slavery that still exist today. The following exhibits how the name has changed but the practice is still the same. Bonded Labor occurs when people have taken a simple loan for something such as medicine, food or housing for themselves or their family and to pay it back they are put to work by the lender creating a type of slavery. With bonded labor often the child of the debtor are put to work in order to pay the bond. Early and Forced Marriage is the parental practice of selling off daughters as they reach adolescence. Daughters are sold for monetary gain. Frequently, there are also religious reasons for this practice. Their families give the girls into arranged marriages. They have no choice as to who they are to marry. Once married they are owned by their new husband. Forced Labor is where a person is forced into work by the threat of physical harm. Much like the slavery that we read of in our history books, these slaves work out of fear of violence. Slavery by Descent means simply that a child is born into slavery. The parents are slaves, thus the child is a slave. It just continues generation after generation. Trafficking, according to the Coalition to Abolish Slavery and Trafficking (C.A.S.T.), is the recruitment and transportation of persons within or across boundaries by force, fraud, or deception for the purpose of exploiting them economically. Trafficked people most commonly work in sweatshops, restaurants, on farms, in manufacturing, prostitution and as private domestic workers Sadly, many parents end up giving their child into slavery to pay off a debt or simply sell their own children for support their families. Many young women are raped by their owners ending up pregnant thus bring more children into the life of slavery. This article could have been written in 1808, or 1908, but sadly, it is being written in 2008. Youd think that in todays civilized society that slavery would truly have been completely abolished, however, the name has just been changed. Slavery affects todays society so much, even though we do not notice it, slavery is everywhere. Next time youre in a department store, pick up some of the products and look to see where they were manufactured. It is highly unlikely that it will have the name of a country with strict child labor laws in place. There are U.S. companies that even move their manufacturing plants outside of the U.S. in order to employ children at a lesser cost. It is extremely hard to believe but most products we use on a daily basis were produced in countries that allow this type of slavery. Products such as sugar, shoes, tea, coffee, chocolate, fruits, and vegetable are made by modern-day slaves. The U.S. Department of Labor disclosed that our countrys largest retailer, Wal-Mart, was fined a measly 135,000.00 for violating child labor laws. The violation: Children operating chain saws and box crushing machinery. Toys-R-Us was cited for working 14-year-old children late into the night. The management for this huge corporations stated that they misunderstood the child labor laws pertaining to how long they could work a fourteen-year-old child. While driving through a large city, maybe in the seedier part of town, notice the young girls on the streets. Where did they come from? Did slave traffickers transplant them here? Are they runaways with no other alternatives? Think about the practices of the Fundamentalist Church of Jesus Christ of Later Day Saints. How is what was going on in Eldorado, Texas any different than sexual slavery? Over 200 women and children were recently taken from this remotely locate temple only after a teenage girl reported that she was being held there against her will and had been forced to marry a fifty year old man as well as have his child. Though illegal, it goes on unknown to most of us to this day. Most of us, unknowingly, support these new forms of slavery. We buy the products from the companies that employ these workers. We, as a nation, do little more than smirk when we read about the religious organizations that condone arranged, under-aged marriages as well as polygamy. In conclusion, though you may not see it, slavery still exists. It has taken on new forms. The name has changed. It doesnt look the same as we have read about in the history books but by any other name it is still slavery. Think about it next time you buy that cute tank top or stop in for your favorite latte.

Architectural Designs Of Castles Vs. Modern Homes :: essays research papers

Is the architectural design of modern homes slowly changing back to the architectural design of castles in the Middle Ages? If design of homes is changing back to design of castles is it a reflection on our society that castles of the Middle Ages were built primarily for defense. Does this mean that as a society we are tying to pull away from each other? There are many similar characteristics and features between modern homes and castles that are incorporated into the design specifically for defense reasons.   Ã‚  Ã‚  Ã‚  Ã‚  Castles in the Middle Ages were built primarily for defense in war. They were constantly being attacked so they had to be built very strong and almost impenetrable. Castles were very large to protect from invaders, but they were definitely not made for comfort. They were very dirty inside, but their main purpose was for defense. Castles were built with very strong walls. Some of the castles had walls that could be as big as thirty feet thick. They also had multiple walls so that if invaders got past the outer wall they still had to get past one or two more, this made defending the castle much easier. The walls were constructed with narrow, wedge-shaped slits in them for archers to shoot arrows at invaders. The outer walls also had holes in the floors for defenders to drop rocks down on invading people who had gotten through the first wall. These holes were called murder holes. Inside the castle were many knights, archers, and soldiers prepared to defend against an yone who breaks all of the way through the walls and gets inside of the castle. Castles also had very large gates and gatehouses to let people into the castle. There was a gatehouse for each wall. Each gatehouse usually had a very large metal and wooden gate that could be lowered into the opening to stop an enemy from getting in or it could be raised to let friends in. Besides huge gates, outer gatehouses also had drawbridges, which could be lowered across moats to let people into the castle. They were also raised to prevent people form getting across. Castles were also built in strategic places so that they could use natural defenses. For instance, some castles were built on the sides of mountains. Others were built in places with many trees surrounding them. Some were built near lakes and rivers, but most of them had moats dug around them.

Political Philosophy Essay examples -- Politics Essays

Political Philosophy Part One (Question 2) Aristotle, Locke, and Hobbes all place a great deal of importance on the state of nature and how it relates to the origin of political bodies. Each one, however, has a different conception of what a natural state is, and ultimately, this leads to a different conception of what a government should be, based on this natural state. Aristotle’s feelings on the natural state of man is much different than that of modern philosophers and leads to a construction of government in and of itself; government for Hobbes and Locke is a departure from the natural state of man. Aristotle’s emphasis is on the city-state, or the political world as a natural occurrence. He says â€Å"every city-state exists by nature, since the first communities do.† (Aristotle 3). Aristotle continually reiterates the notion that the creation of a community comes from necessity; individuals aim at the highest good of all, happiness, through their own rationality, and the only way to achieve happiness is through the creation of the city-state. Aristotle follows the creation of a household and a village to the creation of the city-state in which citizens are able to come together to aim at the â€Å"good which has the most authority of all,† (Aristotle 1) happiness. In turn, this necessity for the formation of a city state comes from the idea of man as a rational being. â€Å"It is also clear why a human being is more of a political animal than a bee or any other gregarious animal†¦ no animal has speech except for a human being.† (Aristotle 4). For Aristotle, human beings are political animals because of their ability to speak, their ability to communicate pleasures and desires, and their ability to reason. Aristotle’s state com... ...ased on their heritage as nobles or the virtues of their fathers. Burke states that â€Å"there is no qualification for government but virtue and wisdom,† (Burke 561). The most compelling argument for Burke against Locke is his idea that â€Å"government is not made in virtue of natural rights, which may and do exist in total independence of it†¦ but their abstract perfection is their practical defect.† (Burke 564). Burke looks at the rights laid out by Locke and Rousseau and scoffs at them, stating that they have no merit in the real world, attractive as they are in principle. He believes that the pretended rights of these theorists are all extremes, and are therefore morally and politically false. Burke believes that â€Å"the rights of men are in a sort of middle,† (Burke 565), and their incapability of definition completely contradicts the extreme rights as defined by Locke.

Taking a Deeper Look at The Piano Lesson by August Wilson Essay

Taking a Deeper Look at The Piano Lesson by August Wilson Winner of multiple awards such as the Tony Award, the New York Drama Critics Circle Award, and the Pulitzer Prize, August Wilson is known most for his forceful cultural plays. Born and raised in Pittsburgh, Pennsylvania, Wilson was born to a white father that later abandoned his family, and a black mother. Wilson dropped out of school in the ninth grade after being accused of plagiarism. Wilson after went to public libraries and read various books; this was an initiation for Wilson and his successful future. When Wilson first started writing he didn’t think he was able to write his own works because of such great writers before him. â€Å"Quote black literature criticism†. However Wilson has managed to accomplish great works such as his second Pulitzer Award winning play, The Piano Lesson. The play introduces an outstanding and dynamic cultural view of many black Americans in the twentieth century. It conveys a family feud that is set off by a piano, a miraculous piano. In The Piano Lesson, August Wilson introduces two siblings, Boy Willie Charles and Berniece Charles Crawley, set in 1937. Wilson first reveals that Boy Willie lives in Mississippi, and Berniece lives in Pittsburgh, Pennsylvania (set of the play). This identification of the two allows the audience and reader to know that there is and will be a difference between the two siblings. The play is about the two siblings and their conflict between the piano. During slavery time, Boy Willie and Bernieces’ grandfather’s (Willie Boy Charles) slave owner Sutter had exchanged their grandmother and uncle for the piano as a gift for his wife. After getting worn out of the piano, Sutter’s wife missed her slaves so much, Sutter had Willie Boy to hand-carve the faces of his wife and son’s faces on the legs of the piano. However, Willie Boy didn’t stop there; he carved all of their ancestors on to the piano. The conflict between Boy Willie and Berniece is set off when Berniece’s husband dies due to stealing the piano with Boy Willie. Because of this, Berniece blames her brother for the cause of her husband’s death. She moves to Pittsburgh after and leaves Boy Willie. When the land that their ancestors worked on is offered to Boy Willie, Boy Willie decides to sell the piano as a down payment. Boy Willie thinks that it’ll b e better to have the land and m... ...to sit in her home unused. She loses all ties with her heritage while in Pittsburgh and only praises the piano for it’s meaning from what she sees on the outside of the piano. The song symbolizes how worthy the piano is; it has to be played. The song is also what makes Sutter’s ghost disappear at the end of the play. It plays a very important role in the play in that it was taught to Berniece by her mother. Perhaps her mother appeared to Berniece spiritually at the end of the play to urge Berniece to play the song again to get rid of Sutter’s ghost. Having Sutter’s ghost appear to Berniece doesn’t only motivate her to play the song, but also sends Boy Willie back to Mississippi. After frightening both Berniece and Boy Willie, it is clear to the two that the piano is more significant than they both thought before. August Wilson does a very fine job by presenting three symbols: the piano, Sutter’s ghost, and the song. All three symbols play major roles and are the foundations of the play. The symbols here allows the reader and audience to tie the history of the Charles family and the feud between Boy Willie and Berniece together. It’s a relation between the past and the present.
