Essay on Effects of the Great Depression - 1418 Words

The Effects of the Great Depression The Great Depression was a horrible event that took place almost 100 years ago. It was a time in our society when people had no money and no food. Everyone was losing their jobs because the companies couldn’t afford to pay them and stay in business at the same time. After the Stock Market crashed and the economy went downhill, a lot of changes were made within the government to make sure that nothing like this would ever happen again. This period in time was a sad period, but there were a lot of good things that happened and took place because of it. In order to really understand all the effects that happened after the Great Depression, you truly needed to live during the time period, but we can’t do†¦show more content†¦As their lives were filled with sadness and no hope, they would soon learn that all of that was about to change for them. As the 1932 Presidential elections were coming up, the citizens had to choose the rig ht person to lead them out of the Great Depression. In November of 1932, the United States held a Presidential Election that was crucial to America. The voting was a one sided outcome, as Franklin D. Roosevelt won the election by a landslide over his opponent Herbert Hoover. In his acceptance speech in 1932 when he was a Democratic Party nominee for running president, he made a promise to the citizens of America that there would be a â€Å"new deal for the American people.† He was determined to keep his promise to the citizens of America, that a new deal was coming. He would later keep that promise and would eventually change the economy for the better. Roosevelt’s â€Å"New Deal Programs† were based on helping the economic problems in several different ways. The programs that he designed were to help; â€Å"federal assistance for people who had lost their jobs, houses, savings, and livelihoods†, â€Å"job creation for the unemployed through massive pub lic works projects†, â€Å"agricultural assistance for troubled farmers†, â€Å"manufacturing assistance for troubled industries†, â€Å"stricter banking regulations to prevent bank failures†, â€Å"creation of the FDIC to protect bank customer’s deposits†Show MoreRelatedThe Great Depression And Its Effects1166 Words   |  5 Pages The Great Depression The Great Depression is one of the single most important events in the financial history of the United States and the world; the effects of and leading to the Great Depression lasted for several years (Shindo).

The Rise of Colonialism and its Impact on Modern Society Free Essays

In the middle of the 1 5th century, as the Roman Empire was weakening, the fall of Constantinople marked a bigger impact than anyone could have considered. The Ottoman Empire had reign to advance into the Mediterranean, and that meant that traveling east on land was not an option. With the Renaissance about to emerge, it became a springboard for the development of advanced ships. We will write a custom essay sample on The Rise of Colonialism and its Impact on Modern Society or any similar topic only for you Order Now This marked the beginning of the Age of Exploration and Colonialism. The Europeans had every advantage. Their immune system had seen all the diseases in the Old World, while he native conquered people’s immune system had only seen a few diseases. The Europeans had far more superior crops and domesticated animals. Cows, pigs, and chicken are considered super animals compared to their wild counterparts, although the wild counterparts do not even exist in the New World. The same could be said for rice, barley, and wheat. The New World had never seen these types of food. The conquered spent their days looking for sustenance while the Europeans were developing guns and telescopes. Because the backbone of the European nations was so developed and stable, their technology and power skyrocketed. With the power, colonization and slavery thrived. From Africa and Asia to the New World, pockets of colonies emerged and developed. Often conquering the entire continent, the colonizers went to work to extract what they thought was important. There were no rights for the conquered. They were in the European man’s world and had to go along for the ride. Racial prejudice rears its ugly head throughout the two World Wars and exists even today. The concept of racism was developed during the Age of Colonialism. The thought that any particular type of person based on looks and color was better did not exist ecause it is not true. But during and after the Age of Colonialism, racism was taught to Europeans and enforced to non-Europeans. Europeans thought that looks and color of the Anglos meant more trustworthiness and intelligence. Unfortunately, the majority of Europeans did not realize that trustworthiness and intelligence are both learned behaviors, and that non-Europeans were taught to be â€Å"uncivilized†. With the conviction of superiority, the Europeans subdued and dominated regions throughout the planet. Africa, in particular, has a long history of colonization from the Europeans. Conquest is defined as the subjugation and assumption of control of a place or people by the use of military force. Major parts of Africa were conquered by the Europeans since ancient times. From the 7th century, Arab trade with sub-Saharan Africa led to a gradual colonization of East Africa, around Zanzibar and other bases. Although trans-Saharan trade led to a small number of West African cities developing Arab quarters, these were not intended as colonies, and while Morocco attempted to conquer areas of the Sahel in the Moroccan war, it was soon forced to withdraw its troops atter pillaging the area. Early European expeditions concentrated on colonizing previously uninhabited islands such as the Cape Verde Islands and S ¤o Tom © Island, or establishing coastal forts as a base for trade. These forts often developed areas of influence along coastal strips, but, with the exception of the Senegal River, the vast interior of Africa was not colonized and was little-known to Europeans until the late 19th century. Vincent Khapoya mentions Ali Mazrui’s three interrelated broad reasons for European exploration of Africa: to increase knowledge, to spread Christianity and to increase national esteem. European enslavement of Africans, and visa-versa, existed along the coasts of East and West Africa since ancient times. The business exploded, however, after the Age of Colonialism was under way. During what was called by the European powers as, â€Å"The Scramble for Africa,† colonization was motivated by the European hunger for African resources. The subsequent exploitation of the African people and the uprooting of their spiritual values by Christian missionaries would leave a permanent European stamp on the continent. Britain took the largest piece of the African cake, rom Cairo to Cape Town, in addition to Nigeria and a few West African regions. It was also the British Empire that in 1894, imposed an arbitrary boundary around the many diverse ethnic groups and kingdoms that would make up modern day Uganda. By exploiting linguistic, ethnic, and cultural differences between the different ethnic groups, Britain’s divide and rule policies created tensions between the divided ethnic groups that helped maintain British rule. Officially, between 1884 and 1906 the Congo was controlled by a company entirely owned by King Leopold. The area was referred to as the ‘Belgian Free State. Until the end of the 1800s this company primarily exported ivory and palm-oil, a lubricant, from the Congo. Only a small profit was made from these products. At the end of the century, however, the world discovered rubber. Soon everyone wanted it to make tires, hoses, tubes, valves and many other products. Rubber is produced from a latex ‘sap’ that came either from a tree or a vine, both of which grew exceptionally well in the Congo Jungle. Because of the new demand, the Belgian companies began demanding massive amounts of rubber from the Jungle and forced the natives to find massive amounts of it and eliver it to them. King Leopold became incredibly wealthy from the sale of rubber and the Congo paid the price. The method that most harvesters used to get the sap destroyed the trees and vines they took it from. Soon the Belgians began to hire soldiers to make sure that the natives produced the raw material. They threatened them with starvation, mutilation or even death if they did not produce enough rubber. Many times they followed through with the threats. Between the 1880s and 1903 the population of the Congo was reduced from over 20 million people to about 8. 5 million. Joseph Conrad, an author who was there during this time, in his book Heart of Darkness, best illustrated what was going on there when one character on his death bed comments on the situation by simply saying: â€Å"the horror, the horror. The term ‘imperialism’ should not be confused with ‘colonialism’. Robert Young writes that imperialism operates from the center, it is a state policy, and is developed for ideological as well as financial reasons whereas colonialism is nothing more than development for settlement or commercial intentions. The Age of Imperialism was a ime period beginning around 1700 when modern, relatively developed nations were taking over less developed areas, colonizing them, or intluencing them in order to expand their own power. Although imperialist practices have existed for thousands of years, the term â€Å"Age of Imperialism† generally refers to the activities of nations such as the United Kingdom, France, Germany, Italy, Japan and the United States in the early 18th through the middle 20th centuries, the â€Å"The Great Game† in Persian lands, the â€Å"Scramble for Africa† and the â€Å"Open Door Policy† in China. Genocide is the eliberate or systematic destruction, in whole or in part, of an ethnic, racial, caste, religious, or national group. The Germans decided that certain ethnic groups were to be eradicated in Namibia. German Lieutenant-General Lothar von Trotha said, ‘l wipe out rebellious tribes with streams of blood and streams of money. Only following this cleansing can something new emerge’. Von Trotha brought with him to German South West Africa 10,000 heavily-armed men and a plan for war. During the period of colonization and oppression, many women were used as sex slaves. â€Å"To receive omen and children, most of them ill, is a serious danger to the German troops. And to feed them is impossible. I find it appropriate that the nation perishes instead of infecting our soldiers. † In the Herero work camps there were numerous children born to these abused women, and a man called Eugen Fischer, who was interested in genetics, came to the camps to study them. He decided that each mixed-race child was physically and mentally inferior to its German father and wrote a book promoting his ideas: â€Å"The Principles of Human Heredity and Race Hygiene†. Adolf Hitler read it hile he was in prison in 1923, and cited it in his own infamous pursuit of â€Å"racial purity’. We can see a trend that follows. For the colonized, life became a living hell. For the colonizers, life became extravagant and easy. These give and take relationships created the modern global economy that we have today. The scars of the past still haunt the wounds of today. Third world countries are still struggling for survival while the well fed first world nations are aligning themselves together to maintain their dominance. While the obvious means of colonization may not be visible, the same characters are in control. How to cite The Rise of Colonialism and its Impact on Modern Society, Papers

We will write a custom essay sample specifically for you Proceed Although the academic literature on terrorism has been largely a theoretical, explanations of the causes and consequences of this phenomenon can be derived from sociological theories. Within sociology, the major frameworks used to examine societal change have been consensus and conflict models. Developed by Friedrich Nietzsche and Karl Marx, respectively, these perspectives have served as the major impetus for sociological theorizing for over a century. Although criminological theorists have shifted away from these polar models, contemporary perspectives on terrorism, as well as on virtually every other form of socially questionable behavior, reflect the influence of Nietzsche or Marx. The two models represent opposite extremes regarding beliefs about human nature, the utility of social institutions, and the rate and type of social change beneficial to society. Our Customers Very Often Tell EssayLab writers: How much do I have to pay someone to make my paper online? Essay writer professionals suggest: Essay Writing Is not Than Hard Although, as Austin Turk notes, a growing number of sociologists eschew both extremes and are working from and toward a model of social reality as variable and dialectical, a basic understanding of the polar models is essential as a starting point for theoretical exploration. At the risk of oversimplification, the dominant themes of the two perspectives are presented below to demonstrate their polarity. An examination of contemporary legal and social responses to terrorism utilizing conflict/consensus as a variable rather than an assumption may create a model capable of predicting governmental response under varying conditions. Karl Marx was optimistic about human nature, believing that people could create a utopian existence on earth. Unfortunately, a shortage of goods and services forced humanity into competition and conflict. As societies progressed through a series of economic-driven political systems (primarily feudalism and capitalism), the working class increasingly became separated from ownership of the means of production. The advent of capitalism found the small businesses of independent craftsperson replaced by factories owned by entrepreneurs who invested nothing more than capital in the production of goods and services. These middlemen later came to be known as the middle class, or bourgeoisie, not because of their income level but as a result of their intercessory role as the buyers of labor from the working class and the sellers of goods to the upper class. Lacking only political power to protect their economic interests, early capitalists in Europe incited social revolutions of the late eighteenth and early nineteenth centuries in Europe that produced the political power desired by the nouveaux riches (Marx 55). Solidifying their hold over society, capitalists further corrupted social institutions, such as the political and legal systems, to control the economic have-nots. Workers increasingly experienced what Marx referred to as alienationa social position as well as an effect that describes the helplessness of the worker when separated from the means of production. Consequently, Marx advocated the rapid dissolution of these social institutions so that a restructured and the more equitable economic system could arise. Revolutionary change, violent if necessary, was seen as necessary to accomplish this dialectic. Terrorism, while not advocated by Marx, was viewed by some of his followers as one way to develop class consciousness, there by inciting the proletariat to revolution (Ibid, 58). In contrast, Friedrich Nietzsche believed that people possessed insatiable desires and viewed social institutions (which Marx disdained) as necessary to control the evil impulses of humans. Furthermore, Nietzsche focused on the way in which these social institutions adapted the master-slave morality. The adverse effects of the industrial revolution in the late nineteenth century led him to conclude, in contrast to Marx, that social change should progress slowly and naturally, thereby giving society time to adapt to dysfunctional relations between institutions that might produce pathological manifestations of social deviance. Not surprisingly, perspectives derived from the conflict model tend to be suspicious of governmental actions, while adherents of the consensus frame-work generally assume that the polity acts in the best interests of its constituents. Nietzsche dichotomizes that the genesis of punishment is one thing and its definitive functions are another thing: [A]ll purposes, all utilities, are only signs that a will to power has become lord over something less powerful and has stamped its own functional meaning onto it (Nietzsche 51). He outlines a variety of functional meanings that punishment has had and continues to have, in support of his hypothesis that the concept of punishment in fact no longer represents a single meaning at all but rather an entire synthesis of meanings, that its history finally crystallizes into a kind of unity that is difficult to dissolve, difficult to analyze andone must emphasizeis completely and utterly indefinable, to which he adds in a parenthesis, only that which has no history is definable (Ibid, 53). Nietzsches observation about the distinction between origins and purposes (or functional meanings) is made in the context of his essay on guilt. Guilt, he speculates, was originally simply an economic debt, but its meaning has evolved and undergone profound changes (Ibid, 35-66). The distinction between origins and meanings is less clear in his discussion of values belonging to the noble and slave modes of valuation taken up in the first essay of the Genealogy. These values became detached, he notes, from their original political contexts and is held now by people who are neither nobles nor slaves. Nobility, for example, became a set of spiritual qualities that were originally associated with the political elite but might, in fact, be possessed by individuals regardless of their social origins and might be lacking in some of the privileged. Other than that, it is not clear what changes, if any, noble and slave values have undergone. The meanings of these values appear, in Nietzsches account, more highly colored by their origins than the meanings of guilt and punishment as discussed in Genealogy 2. Nietzsche presents the judgment bad as coming, originally, from the perspectives of noble elites, aristocrats, who first of all joyously affirmed themselves as good (exceptional, fortunate, happy, beautiful, powerful, and so on) and then, and only by comparison, looked down on common folk as bad, that is, inferior (ordinary, common, miserable, unfortunate, ugly, and so on). He presents judgments of evil (dangerous, destructive, harmful, hurtful) as coming, originally, from the perspectives of the impotent masses, slaves, common people, who regarded as evil those who conquered and enslaved them, and then, and only by comparison, found themselves to be good (not dangerous or harmful but helpful, nice, accommodating, pleasant, and so on). Thus, he represents the noble mode of valuation (good vs. bad) as originating in a powerful victors perspective and the slave mode (good vs. evil) in that of a relatively impotent victim. perspectivism may be understood as the idea that perspectives furnish all the material we have for comprehending the world and for the concepts we use to do so. In its unraveling of the ancestral lines of a concept, genealogical investigation yields a variety of perspectives. We may understand his perspectivism simply as the idea that all thinking, like all perception, is from some angle or other and that the only way to correct errors is also from some angle or other. Thinking from a perspective does not imply distortion but only a bias, a slant, which has limitations but also may offer special vantage points. The thinking within the limits of a particular bias (slant) may be good or bad, distorted or true, or exhibit some combination of truth and distortion. Whether Nietzsche would have agreed with it or not, this interpretation of his perspectivism makes good sense of his own evaluations and evaluations. Generally, examinations of terrorism from these two perspectives have focused on two issues: 1) the causes of terrorism and 2) a governments response to terrorism. Regarding the first issue, authoritative examinations of the causes of terrorism from either a consensus or conflict perspective have been rare. While consensus theorists have hinted that terrorism reflects the revolutionary's inability to adapt to the strains of a society experiencing disjunction between cultural goals and means to achieve, conflict theorists have suggested that terrorism indicates excessive frustration over the speed with which social change is progressing. Although a discussion of the causes of terrorism from both of these approaches is warranted (in fact, badly needed), our purpose is an examination of the second issuethe polity's response to terrorism. Consequently, while passing reference may be made to causative factors (indeed, governmental response and the labeling of terrorism may be viewed as ca usative), this work is most concerned with the manner in which conflict and consensus theories might interpret and predict governmental reactions to terroristic violence. In toto, terroristic activities are deeply rooted in the capitalistic nature of the society, that because competition and valuation exist, the society is led astray from the possibility of obtaining a utopic society. Social institutions paved the way to the alienation of the workers, and thus resulted to their dismal existence. This is exactly how terrorism originated for Marx, and the only solution is to dissolve all social institutions. Nietzsche also argues that social institutions must be dissolved (he term this as anti-establishment) because according to him for as long as there is a schematization in society, then the morality that will thrive within that society is perverse. And since it perverse, the master-slave morality will be prevalent, thus members of society will adopt terrorism just to advantage their own causes. Thus, terrorism is a by-product of institutionalization of the society and posting of schemas that will establish a society for capitalistic gains and misappr opriation of the slaves.

Hydraulics Pneumatics Essays

Hydraulics Pneumatics Essays Hydraulics Pneumatics Essay Hydraulics Pneumatics Essay HYDRAULICS IN MISSILES Nowadays, the electro-hydraulic actuator plays an important role in some modern tactical missiles. High power, great robustness and high tracking precision are the most significant demands for the missile actuator. Therefore an advanced method of active disturbance rejection control (ADRC) is presented aiming at the dynamics of the system are highly nonlinear and have large extent of model uncertainties, such as tremendous changes in load. Firstly, a novel ADRC controller is designed for estimating and compensating disturbance based on the mathematical model of missile electro-hydraulic actuator. Then, the influence of rudder load on the system performance is analyzed in this paper. Simulation results show that the ADRC control approach can decrease the tracking error and enhance the robustness of missile electro-hydraulic actuator system when the rudder load changed tremendously. But the phenomenon of Anti-Control has disadvantageous effect on the transition period of actuator loop and evenly causes the system divergence. HYDRAULIC SUSPENSION IN BOGIES The application of oil-hydraulic actuators for active suspension of railway vehicles has been examined experimentally by using a 3-DOF half-vehicle model. The LQG control law was adopted, in which state variables were estimated from measurable ones on the actual railway vehicle. The results show the possibility that the controllable frequency range extends with the oil-hydraulic actuator. The addition of bogie acceleration measurement to body related measurement provides a significant advantage for the performance. When actual body weight becomes lighter than that of the controller design value, the control performance and the stability deteriorate. Therefore, it is recommended to use the empty car body weight for design of the active suspension controller. The control effect can reach to the maximum vibration isolation level by shortening the sampling period to 2 ms PNEUMATIC GREASE GUN A grease gun is a common workshop and garage tool used for lubrication. The purpose of the grease gun is to apply lubricant through an aperture to a specific point, usually on agrease fitting. The channels behind the grease nipple lead to where the lubrication is needed. The aperture may be of a type that fits closely with a receiving aperture on any number of mechanical devices. The close fitting of the apertures ensures that lubricant is applied only where needed. There are three types of grease gun: A grease gun (pneumatic) 1. Hand-powered, where the grease is forced from the aperture by back-pressure built up by hand cranking the trigger mechanism of the gun, which applies pressure to a spring mechanism behind the lubricant, thus forcing grease through the aperture. 2. Hand-powered, where there is no trigger mechanism, and the grease is forced through the aperture by the back-pressure built up by pushing on the butt of the grease gun, which slides a piston through the body of the tool, pumping grease out of the aperture. . Air-powered (pneumatic), where compressed air is directed to the gun by hoses, the air pressure serving to force the grease through the aperture. Russell Gray, inventor of the air-powered grease gun, founded Graco based on this invention The grease gun is charged or loaded with any of the various types of lubricants, but usually a thicker heavier type of grease is used. It was a close resemblance to contemporary hand-power ed grease guns that gave the nickname to the World War II-era M3 submachine gun. PNEUMATICS IN AIRCRAFT Bleed air in gas turbine engines is compressed air taken from within the engine, after the compressor stage(s) and before the fuel is injected in the burners. While in theory bleed air could be drawn in any gas turbine engine, its usage is generally restricted to jet engines used in aircraft. Bleed air is valuable in an aircraft for two properties: high temperature and high pressure (typical values are 200-250Â °C and 275 kPa (40 PSI), for regulated bleed air exiting the engine pylon for use throughout the aircraft). 1] This compressed air can be used within the aircraft in many different ways, from de-icing, to pressurizing the cabin, to pneumatic actuators. However, bleed air is quite hot and when being used in the cabin or other low temperature areas, it must first be cooled or even refrigerated by the aircrafts environmental control system (ECS). Newer aircraft rely more on electricity, reducing the need for compressed air. Since most gas turbine engines use multiple compressor stages, some newer engines have the bleed air inlet between compressor stages to reduce the temperature of the compressed air.

Heres How Crabs Find Food

Here's How Crabs Find Food Crabs may be a favorite food for some people, but they need to eat too. They often live in dark or muddy areas, where it can be difficult to find prey by eyesight. So how do crabs find food, and how do they eat? And, interestingly, what types of food do they like to eat? How Crabs Find Food Like many other marine animals, crabs rely on their sense of smell to find prey. Crabs have chemoreceptors that allow them to detect chemicals in the water that are released by their prey. These chemoreceptors are located on a crabs antennae. These are long, segmented appendages near the crabs eyes that have both chemoreceptors and allow them to feel its surroundings. Crabs also have antennules, shorter antenna-like appendages near the antennas that allow them to sense their environment. A crab can taste using hairs on its mouthparts, pincers and even its feet. Senses of Taste and Smell Crabs have pretty well-developed senses of taste and smell. Fishing for crabs, or crabbing, using pots and cages relies on these senses, and makes it possible to catch crabs. The pots are baited with a variety of smelly things, depending on the target crab species. Bait can include chicken necks, pieces of fish such as eel, menhaden, squid, herring and mackerel. As the bait hangs in the trap in a bag or in a bait jar, odorous chemicals waft out into the ocean, attracting hungry crabs. Depending on water flow, these conditions can affect their senses to detect prey. What and How Crabs Eat Crabs arent picky eaters. They will eat everything from dead and living fish to barnacles, plants,  snails, shrimp, worms and even other crabs. They use their claws to grab food particles and put the food into their mouths. This is similar to the way humans eat using their hands or utensils. Crabs also use their claws to manipulate or break up the food so they can place it into their mouths more easily in smaller bites. When crabs have to break through shells of other sea life, their strong claws come in especially handy while their other appendages help them quickly move to catch various types of prey. Different Crabs, Different Diets Different crabs like to eat different types of sea life and plants.  Dungeness crabs, for example, may snack on squid and worms, while king crabs like to nosh on clams, mussels, worms and sea urchins. Basically, king crabs hunt for prey on the ocean floor and often eat decaying animal matter as well as live sea life.

Karl Marx & Political Life Term Paper Example | Topics and Well Written Essays - 750 words

Karl Marx & Political Life - Term Paper Example It was these that guided these revolutionaries in their struggles to change the status quo and introduce a new system in society. At the core of Marxist ideas is the tool of analysis that is to be used in understanding the essential features of society. The Marxist social analysis is actually the most essential principle behind the socialist ideology. Without social analysis, it is apparently impossible to discover the factors that could lead to the progress of society from one historical stage to another. Without it, the leadership of such movements for change would not be able to identify the motive forces as well as those that would seek to maintain the status quo. As a social scientist, Marx was among the first to articulate that to understand society, it is necessary to focus on the material basis of its existence, the economy. He actually began his investigations of society by first understanding the dynamics of capitalist economy, particularly its mode of production. It was th rough his observations in the relationship among the people involved in production that he was able to formulate a theory about social classes and the political structure arising from it. Therefore, Marx does not consider politics as independent from economic life. Instead, he considers it to be a reflection of the relations in production. At the same time, however, he also explains that the nature of the economy can also be altered by changes in politics. Even as Marx formulated a social theory that eventually led to the organization and mobilization of the working class for social change, he was not a worker himself. A lawyer by training and education, he belonged to the middle class. Therefore, it was impossible for him develop the political standpoint and ideological viewpoint of the proletariat. However, he was drawn to socialist ideas and was also a Hegelian; both of which were contributing factors to his determination in learning about the potential elements that could lead t o radical social transformation. As a socialist, Marx appreciated the benefits of a society where there are no distinctions based on wealth and participation on labor. As a Hegelian, he was also very interested in discovering dialectics in society; the contradictions that could lead to change. Aside from being a socialist and a Hegelian, Marx also upheld the principal aspects of political economy as articulated by Adam Smith and David Ricardo, especially in the concept that the wealth of society originates from the combination of nature and human labor. All these were vital to the development of Marx’s systematic theory. Inspired by his socialist principles and Hegelian-influenced methods of analysis, Marx went on to investigate the mode of production.
