A pest causes damage to agriculture by feeding on crops. For example, boll weevil is a pest on cotton. It attacks the cotton crop, thereby reducing its yield. Weeds also reduce crop productivity by competing with the main crop for nutrients, light, and space. Similarly, abiotic factors such as salinity, temperature, etc. affect the net crop production. Some natural calamities such as droughts and floods are unpredictable. Their occurrence has a great impact on crops sometimes, destroying the entire crop. Question 2: What are the desirable agronomic characteristics for crop improvements Answer: The desirable agronomic characteristics for crop improvements are: (i) Tallness and profuse branching in any fodder crop. (ii) Dwarfness in cereals. These desirable agronomic characteristics help in increasing crop productivity.

They are six in number. Since they are required in large quantities, they are known as macro-nutrient. The six macro-nutrients required by plants are nitrogen, phosphorus, potassium, calcium, magnesium, and sulphur. Question 2: How do plants get nutrients Answer: Plants require sixteen essential nutrients from nature for their growth and development. All these nutrients are obtained from air, water, and soil. Soil is the major source of nutrients. Thirteen of these nutrients are available from soil. The remaining three nutrients (carbon, oxygen, and hydrogen) are obtained from air and water.

Answer: Manures increase soil fertility by enriching the soil with organic matter and nutrients as it is prepared by the decomposition of animal excreta and plant wastes. On the other hand, fertilizers are mostly inorganic compounds whose excessive use is harmful to the symbiotic micro-organisms living in soil. Their excessive use also reduces soil fertility. Hence, fertilizers are considered good for only short term use.

(b) Farmers use ordinary seeds, adopt irrigation and use fertilizer. (c) Farmers use quality seeds, adopt irrigation, use fertilizer and use crop protection measures. Answer: (c)Farmers using good quality seeds, adopting irrigation, using fertilizers, and using crop protection measures will derive most benefits. (i) The use of good quality seeds increases the total crop production. If a farmer is using good quality seeds, then a majority of the seeds will germinate properly, and will grow into a healthy plant. (ii) Proper irrigation methods improve the water availability to crops. (iii) Fertilizers ensure healthy growth and development in plants by providing the essential nutrients such as nitrogen, phosphorus, potassium, etc. (iv) Crop protection measures include various methods to control weeds, pests, and infectious agents. I f all these necessary measures are taken by a farmer, then the overall production of crops will increase. Page 5 of 14 Class IX Chapter 15 â€Å" Improvement in Food Resources Science Question 1: Why should preventive measures and biological control methods be preferred for protecting crops Answer: Preventive measures and biological control methods should be preferred for protecting crops because excessive use of chemicals leads to environmental problems. These chemicals are also poisonous for plants and animals. Preventive measures include proper soil and seed preparation, timely sowing of seeds, intercropping and mixed cropping, usage of resistant varieties of crops, etc. On the other hand, biological control methods include the usage of bio-pesticides that are less toxic for the environment. An example of bio-pesticides is Bacillus thuringenesis,which is an insect pathogen that kills a wide range of insect larvae. Therefore, both preventive measures and biological control methods are considered eco- friendly methods of crop protection. Question 2: What factors may be responsible for losses of grains during storage Answer: During the storage of grains, various biotic factors such as insects, rodents, mites, fungi, bacteria, etc. and various abiotic factors such as inappropriate moisture, temperature, lack of sunlight, flood, etc. are responsible for losses of grains. These factors act on stored grains and result in degradation, poor germinability, discolouration, etc. Page 6 of 14 Class IX Chapter 15 â€Å" Improvement in Food Resources Science Question 1: Which method is commonly used for improving cattle breeds and why Answer: Cattle farming is commonly used for improving cattle breeds. The purpose of cattle farming is to increase the production of milk and draught labour for agricultural work. Dairy animals (females) are used for obtaining milk and draught animals (males) are engaged in agricultural fields for labour work such as carting, irrigation, tilling, etc. Cross breeding between two good varieties of cattle will produce a new improved variety. For example, the cross between foreign breeds such as Jersey Brown, Swiss (having long lactation periods) and Indian breeds such as Red Sindhi, Sahiwal (having excellent resistance power against diseases) produces a new variety having qualities of both breeds.

Answer: Poultry in India is the most efficient converter of low fibre food stuff into highly nutritious animal protein food. In poultry farming, domestic fowls are raised to produce eggs and chicken. For this, the fowls are given animal feeds in the form of roughage, which mainly consists of fibres. Thus, by feeding animals a fibre rich diet, the poultry gives highly nutritious food in the form of eggs and chicken. Page 8 of 14 Class IX Chapter 15 â€Å" Improvement in Food Resources Science Question 1: What management practices are common in dairy and poultry farming Answer: Common management practices in dairy and poultry farming are: (i) Proper shelter facilities and their regular cleaning. (ii) Some basic hygienic conditions such as clean water, nutritious food, etc. (iii) Animals are kept in spacious, airy, and ventilated place. (iv) Prevention and cure of diseases at the right time is ensured. Question 2: What are the differences between broilers and layers and in their management Answer: Layersare meant for egg production, whereas broilers are meant for poultry meat. Nutritional, environmental, and housing conditions required by broilers are different from those required by egg layers. A broiler chicken, for their proper growth, requires vitamin rich supplements especially vitamin A and K. Also, their diet includes protein rich food and enough fat. They also require extra care and maintenance to increase their survival rate in comparison to egg layers. Page 9 of 14 Class IX Chapter 15 â€Å" Improvement in Food Resources Science Question 1: How are fish obtained Answer: Fish can be obtained by two ways: (i) Capture fishing: It is the process of obtaining fish from natural resources. (ii) Culture fishery: It is the practice of farming fishes. Farming can be done in both freshwater ecosystem (which includes river water, pond water) and marine ecosystem. Question 2: What are the advantages of composite fish culture Answer: An advantage of composite fish culture is that it increases the yield of fish. In a composite fish culture, five or six different species are grown together in a single fish pond. Fishes with different food habitats are chosen so that they do not compete for food among themselves. Also, this ensures a complete utilization of food resources in the pond. As a result, the survival rate of fish increases and their yield also increases. Page 10 of 14 Class IX Chapter 15 â€Å" Improvement in Food Resources Science Question 1: What are the desirable characters of bee varieties suitable for honey production Answer: Bee varieties having the following desirable characters are suitable for honey production: (i) They should yield high quantity of honey. (ii) They should not sting much. (iii) They should stay in the beehive for long durations. (iv) They should breed very well. Question 2: What is pasturage and how is it related to honey production Answer: Pasturage is the availability of flowers from which bees collect nectar and pollen. It is related to the production of honey as it determines the taste and quantity of honey. Page 11 of 14 Class IX Chapter 15 â€Å" Improvement in Food Resources Science Question 1: Explain any one method of crop production which ensures high yield. Answer: Crop rotationis one of the methods of crop production that ensures high yield. It is the method of growing two or more varieties of crops on the same land in sequential seasons. A crop utilises some particular nutrients in larger quantities from the soil. Then, if the same crop is grown in subsequent seasons those nutrients will get depleted in the soil. Therefore, crops having different nutrient requirements are rotated. For example, legumes which have nitrogen-fixing bacteria in their root nodules supply the soil with nitrogen. Therefore, these legumes are rotated with nitrogen requiring cereals such as wheat and maize. This method reduces the need of fertilizers, thereby increasing the overall yield of crops. Question 2: Why are manures and fertilizers used in fields Answer: Manures and fertilizers are used in fields to enrich the soil with the required nutrients. Manure helps in enriching the soil with organic matter and nutrients. This improves the fertility and structure of the soil. On the other hand, fertilizers ensure a healthy growth and development in plants. They are a good source of nitrogen, phosphorus, and potassium. To get an optimum yield, it is instructed to use a balanced combination of manures and fertilizers in the soil. Question 3: What are the advantages of inter-cropping and crop rotation Answer: Inter-cropping and crop rotation both play an important role in increasing the yield of crops. Inter-cropping helps in preventing pests and diseases to spread throughout the field. It also increases soil fertility, whereas crop rotation prevents soil depletion, increases soil fertility, and reduces soil erosion. Both these methods reduce the need for fertilizers. It also helps in controlling weeds and controls the growth of pathogens and pests in crops. Page 12 of 14 Class IX Chapter 15 â€Å" Improvement in Food Resources Science Question 4: What is genetic manipulation How is it useful in agricultural practices Answer: Genetic manipulationis a process where the gene for a particular character is introduced inside the chromosome of a cell. When the gene for a particular character is introduced in a plant cell, a transgenic plant is produced. These transgenic plants exhibit characters governed by the newly introduced gene. For example, let us assume there is a wild plant that produces small fruits. If the gene responsible for a larger fruit size is introduced in this plant, this plant becomes transgenic, and starts producing larger fruits. Similarly, genes for higher yield, disease resistance, etc. can be introduced in any desired plant. Therefore, gene manipulation plays an important role in agricultural practices. It helps in improving crop variety. It ensures food security and insect resistant crops. It also improves the quality and yield of crops. Question 6: How do good animal husbandry practices benefit farmers Answer: Cattle farming is one of the methods of animal husbandry that is most beneficial for farmers. Using this method, better breeds of draught animals can be produced. Such draught animals are engaged in agricultural fields for labour work such as carting, irrigation, tilling, etc. Question 7: What are the benefits of cattle farming Answer: Benefits of cattle farming: (i) Good quality and quantity of milk can be produced. (ii) Draught labour animals can be produced for agricultural work. (iii) New variety that are resistant to diseases can be produced by crossing two varieties with the desired traits. Page 13 of 14 Class IX Chapter 15 â€Å" Improvement in Food Resources Science Question 8: For increasing production, what is common in poultry, fisheries and bee-keeping Answer: The common factor for increasing production in poultry, fisheries, and bee keeping is the proper management techniques that are to be followed. Regular cleaning of farms is of utmost importance. Maintenance of temperature and prevention and cure of diseases is also required to increase the number of animals. Question 9: How do you differentiate between capture fishing, mariculture and aquaculture Answer: Capture fishing It is the method of obtaining fishes from natural resources. Mariculture It is the culture of marine fishes for Aquaculture It involves the production of aquatic animals that are of high economic value such as prawns, lobsters, commercial use. fishes, crabs, etc. Page 14 of 14

Discussion Essay Example | Topics and Well Written Essays - 500 words - 53

Discussion - Essay Example Most people have a reluctance to find reliable and trusted resources about important national and government events. Studies also reveal that facts have little effect in changing people and their perception towards the government operations. Political ignorance has been paramount for a number of years and people often base their opinions based on beliefs rather than democratic ideals and human intelligence. Facts ought to dictate beliefs and preconceived notions. People should dedicate time to learn more about the government and its policies. People tend to seek consistency as they interpret information to their beliefs. Through motivated reasoning, people should strive to accept that the sophistication of governance alters existing norms to incorporate structural or political development. Through E-government portals, the public should access any government events or services. E-governments are responsible in ensuring effectiveness in government delivery services as well as simplifying the compliance of citizen participation and government regulations. Through the e-government orientation, citizens will participate in government activities and strengthen their trust. This action will also ensure cost-effective business practices and responsive, streamlined government services are achieved. The access of information will allow people to access various government services and information. People will also participate in democracy and cause a great impact as to how the government can interact efficiently with its citizens. The e-government has various benefits regarding the participation of the public. More people will have free access to various platforms in which they can express their opinions in the government. For example, a certain minister may choose to get opinion about certain amendments to the constitution that he or she may wish to make. It is important that the public participate in these proposed new

Reaction #2 - Term Paper Example With the progressive change in warfare after the Second World War, more questions have been raised on how to deal with asymmetrical warfare under the Geneva conventions. After this convention of 1949, most nations’ security has been threatened non-state actors organizations such as ISIS and al-Qaeda are not fully covered by the rules of war. The armed groups have over and over again sought to defeat their military weakness by employing strategies that deliberately violet international law. These range from planned attacks against civilians, sexual violence, forced conscription as well as using civilians to guard military objectives (Slomanson, 1999). The risks of civilians are further increased as military superior parties, in fighting the rival that is often tricky to identify, responds with means and methods of warfare that may violet the principles of difference and proportionality, giving rise to further civilian victims. International armed conflict between the states and terrorist non-state actors raises a concern on how states in question should actually respond to these groups considering the fact that they have comparatively few rights under the international Humanitarian Law. There is also a big concern as to whether the wars on the non-state actors are international or non-international under Geneva Conventions. But on the other hand, the involved states also consider these rebellious groups as illicit combats who are dispossessed of any legality; their actions are unsympathetically punished in line with the domestic laws of the state. The context of these armed conflicts is claims of legitimacy, as the state pretends to have a greater claim to legitimacy than non-state actors. States seek to de-legitimize non-state actors’ claim while advancing their own claims of legitimacy (Slomanson, 1999). The non-state actors should not be

African Americans History As Slaves And Contemporary Poverty History Essay

African Americans History As Slaves And Contemporary Poverty History Essay It is often argued that the main cause of Africas poverty rates is mainly related to the lack of pro-growth derived from either the colonial system or the period of slavery. (Jerven, p.77) This argument has recently been applied to the United States social scene in order to explain the existent and continuing problems of income and economic inequality especially within the African American race. In fact, the phenomenon is so troubling that several campaigns have been recently launched to combat the problem. Among these is the Campaign to Reduce Poverty in America whose aim is to accomplish a decrease of 50% in poverty rates by 2020. (Catholic Charities USA) The problem of poverty is thus present and confirmed in the high rates of unemployment, the social disparities and the various and different attempts to deal with the problem whether by private, religious or governmental organizations. However, what is especially interesting to analyze further in this discussion are the causes of this social and economic problem. The origins of poverty are for example drawn upon by Gunja SenGupta in his book From Slavery to Poverty: The Racial Origins of Welfare in New York, 1840-1918, in which he argues that the historic roots of the problem run deeper than the present which consequentially implies the need to reflect on historic events that could be a determinant and influential factor in the continuance of contemporary social dilemmas. (NYU Press) This author is not the only person who perceived a link between poverty and historical problems such as slavery. In fact, although slavery was abolished over a hundred and forty years ago many people believe that the enslavement of humans has continued in the less direct but similarly hash and cruel form of poverty; a belief that challenges the notions of slavery itself. In short, the current problem of African American poverty is intrinsically related to the long history of subjugation, oppression and racial segregation that we re in their turn caused by the slavery system. Poverty is indeed a reality in America, a country that is considered to be among the richest and most progressed nations in the world. According to the US Census Bureau, 35.9 million people live below the poverty line in America, a number that includes also around 12.9 million children. The statistics are in fact shocking when gathered together. For example, according to the Bread for the World Institute, 3.5% of U.S households experience hunger which means that some members within these families skip meals or eat less than required to sustain a healthy lifestyle. (Siddiqi) The facts are more troubling when applied to the African American community. In a country where 12 percent of the population is black it is also noted that approximately a quarter of African Americans are classified as poor, a problem that has been part of the American social scene for many years. Poverty is thus very common among the members of this particular race. Poverty among African Americans is deeply conne cted to many issues among which is the lack of proper education that many African American children still do not receive. This decreases the chances of good employment and increases the possibility of experiencing poverty. There are other reasons through which to understand the problem of poverty among African Americans. However, what is interesting to reflect on further is the relationship between these high rates of poverty among African Americans and the problems of race and inequality that are still found socially and do impact the quality of life of the blacks in America. As Jonathan Alter, a writer for Newsweek, pointed out: Poverty is caused by a tangle of financial and personal pain that often goes beyond insufficient resources and lack of training, wage stagnation, social isolation, and a more subtle form of class-based racism. (Green) This quote affirms the existence of deeper rooted cause as an explanation of African American poverty. The link between racism and lesser op portunities and chances to advance are clear and hardly require any further elaboration. Since racism is related to the institutionalized system of slavery it is hence important to draw further on the significance of this system in the continued existence of poverty among African Americans. One of the most famous statements in the Declaration of Independence that has come to be part of what being an American means is: We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. This sentence is one that stipulates the basic human rights of every American citizen which is freedom, equality, safety and equal chances to realize their dreams of economic prosperity. This sentence has been quoted during the era of the Civil War and the Civil Rights movements to argue against the injustice of slavery that the black people were subjected to. However, equality for all was never part of the social reality even after the abolition of slavery. The perception of white people regarding the blacks was one of superiority that minimized and trivialized the importance of any contribution that could be possibly made by African Americans. For this reason, blacks were denied the same education opportunities as white people which only added to the poverty rates. The fact is that African Americans still lag behind in education attainment compared to white or other minority groups such as Asian Americans. African Americans attend college at half the rate of white citizens. (Kozol, p.26) The historic problem of segregation is deeply linked to these current statistics. Since education empowers an individual to compete in the work force it is hence evident why over a quarter of African Americans continue to experience poverty. Slavery expanded quickly from the time of is introduction until the beginning of the Civil War that lasted from 1861 to 1865. By the time the war started, nearly 4 million slaves were part of the southern society. Their work was diverse but was founded mainly on the principle of sustaining and enhancing the agricultural economy. They picked or planted cotton. Some other blacks worked within the house. There were slaves trained in the art of blacksmiths or carpentry among others. Slavery was a diverse system that was spread across different sectors of society in the South. Yet, what all types of work had in common is the deprivation of all black people from their rights of choice and ability to earn anything dignifying, materialistically or emotionally, from their work. Slavery is one of the most well-documented, well-known yet not most pride igniting phases of American history. It has effectively managed to leave its impacts on society, racial integration and ethnic tolerance throughout the centuries since its abolishment and up to the present day. African Americans were enslaved for centuries beginning with the time the United States came into existence in the 17th century until after the Civil War when slavery was officially declared to be unconstitutional. The War itself was mainly caused as a result of the differences in opinion about the issue between the Northern states, the abolitionists, and the Southern states, that depended on the slave system for the maintenance and growth of their agricultural economy. The history of slavery in the United States is however more complicated than a simple time line can serve to shed light on. The institution did not simply start for one obvious reason at one specific time and the same thing can be said ab out the way it came to an end after the Civil War. Though the wars purpose was the liberation of slaves and the provision of equal rights for all, slavery did not stop right after the war and continued to be part of the social picture, though to a lesser extent, especially in certain Southern regions. Southern states did especially not desire to completely eliminate the institution of slavery, which was an integral part of their economy, leading with that to the development of a complicated pattern in how the issue came to be dealt with right before, during and after the Civil War. All this implies that slavery was based on the exploitation of individuals for profit; an aspect of the system that served to dehumanize the black population to grave extents. This dehumanizing dimension of slavery served to complicate the integration of African Americans and led to problems of racism and deep-rooted rejection of their integration in American society. This rejection has on the other hand impacted the economic conditions of the blacks as it extended over all areas of life including work and education. It is no secret that there was a sharp division historically between the Southern and Northern states about the subject of slavery. What is however pertinent in this fact is its application to the economic conditions of blacks in the North versus the South during the 19th century. Racism was more prevalent in the South where many states refused to loosen their harsh racial policies that restricted African Americans to working mainly working in the fields. Though racism was also present in the northern states it was less severe and allowed the black population the opportunity to prosper culturally and intellectually; a growth that is for example evident in the Harlem Renaissance. However, despite these periods of flourishing, the history of African Americans is especially characterized by inequality; an inequality whose main cause is directly related to the centuries of enslavement. As noted before, racism is one of the main causes of the continued economic disadvantage of many Africa n Americans. When slavery was ended, notions as natural rights were socially introduced and impacted the perception of blacks of their own role in society. Blacks started becoming aware of the extremely suffocating environment that they were part of and which desperately attempted to keep them in the dark about their rights a human beings and citizens of a nation based on the principles of equality for all. (Mcpherson, p.39) It are these aspects and perceptions of oppression, cruelty and savageness of treatment for the mere promotion of selfish economical gain that continue to generate feelings of freedom and oppression which has managed , and continues, to make the greatest difference nowadays in the interaction of black and white people. Though theoretically slaves were no longer slaves after the Civil War, they continued to be treated as an extremely inferior race. This was of course different from area to another. In the south, ex-slaves were treated with the same attitude as before the Civil War while in northern states, where the bitterness was more directed towards white southern Americans rather than African-Americans, ex-slaves were treated better than slaves yet not fully as citizens. Emancipation had become a reality with the end of the war but it remains obvious that the place of African-Americans in society was far from being either resolved or clear. The questions that arose consequentially about race served to define the discourse and the relationships between the two different races and are still traceable in the many sensitive taboos that characterize certain racial subjects and words. In the aftermath of the Civil War, practical problems arose in the south in regard to the manner of integrating slaves within society. Whether the freedmen ought to be regarded as citizen and be granted rights as the ability to possess property was central to the debate. Voting rights were another concern as they gave significant importance to the freedmen enabling them to contribute and impact society and their level of prosperity within it. The most important question of all seemed however to revolve around the possibility or impossibility of the peaceful co-existence of blacks and whites together which is a question history has managed to answer so far. (Tallant, p.5) The rise of intolerance, the problem of segregation and the prevention of blacks from voicing their economic or political needs through the democratic voting system have all led to the enhancement of sentiments of antagonism among both sides which led to the blacks desire to create their own defensive and distinct identity that was at the core resentful of white peoples influence, and led the white population to adopt on the other hand a segregated and superior outlook. This shows how the history of slavery and the subsequent rise of the problems of racism distanced the two groups from interacting and mutually benefitting from the same opportunities. In short, because of slavery and racism many blacks did not and do not get the chance to benefit from the same opportunities as white people which complicates the chances of finding a good job later on and increases as a result the chances of poverty. Blacks continued to work mostly on lands owned by white farmers due to the aforementioned complications that arose when they desired to purchase a piece of land for themselves. Neither the federal government nor the local people seemed to support that and the final choice they were left with in the post war era was to keep working for the white planters. There was of course a difference in the way they lived compared to the period before the war. The freedmen exercised now more control over their lives and could not be treated with the same inhumanity as before. They did not have to work before sunrise and continue until after sunset. They could determine their workload more favorably compared to their previous working conditions. They could also determine whom of their family members they wished to be part of the plantation work. Previously, their children were forced at an early age to do the work and this could be prevented with the choices they had after he Civil War. This does o f course not mean that the situation changed dramatically to the better including complete freedom and equal rights. To claim that is to dismiss the fundamental aspect about social change: it happens gradually. The living conditions had simply significantly improved from the completely intolerable to the harsh and challenging. Overcoming the social challenges caused by their racial status proved to be a long and trying process that spanned over many years and continues until the present day in the form of the continued attempt to decrease the problems of the black community such as a high level of crime, poverty and a lower rate of educational degrees among the youth. The fact is that blacks have been perceived to be inferior for a long time in America which is a prejudice that affected the opportunities available for this particular race and hence impacted their current economic social position. It is thus undeniable that slavery had an extremely malignant and negative influence on the development of African- American culture and identity. Being regarded as an inferior race, especially in the South where the idea was the main justification provided to legitimize the slavery institution, was detrimental to the enhancement of any sense of pride in ones heritage. The change towards that began only slowly. The way they were treated, the destruction of any sense of belonging and attachment to their African heritage during the years of enslavement, the restriction of simple communication between slaves are all facets of slavery that significantly influenced the emancipation process and the development of the African-American culture in addition to complicating the nature of relationships and the form of interaction between whites and blacks. Slavery disrupted thus the sense of belonging to the African heritage and led to the emergence of a defensive attitude among blacks. Even aft er emancipation, slavery continued to play a role on African Americans future and chances of progress. This is evident in the themes of their music and art whether written or visual. These themes deal often with the idea of social inequality, oppression and economic disadvantage as a direct consequence of racial history. Slavery made blacks without doubt socially disadvantaged and led to the subsequent rise of the Civil Rights Movement in the 20th century. The racism and harassment that African Americans have had to deal with is still part of the races consciousness until the present day. This is nowhere signified but in the multitude of subjects that continue to rise a sense of sensitivity when brought up. It is thus no exaggeration to conclude that slavery has left a tremendous impact on the African-Americans as a whole. The resolution of such a problem had to be done, and continues to be struggled with, over the period of two centuries. Overcoming the past completely has proven t o be impossible. The history of enslavement is part of what defines every African-American up to the present despite many peoples refusal to admit this. Though most blacks do not reflect on the period of enslavement, the impacts of it, in the form of social disadvantages still experienced through work and educational chances, are not easily dismissible and serve as a harsh reminder.(Healey, p.175) The removal of their culture, the limitation of their freedom, the oppression of their most fundamental basic rights for centuries, and the final negative development of social distinctions between blacks and whites in the period after emancipation, have all managed to impact the culture the African-American ethnic group has since then created a culture whose characteristics include for example less favorable economic conditions for millions of African Americans. Slavery has thus proven to be a very powerful institution whose impacts are hard to erase. The discussion of poverty among African Americans in the present day is thus incomplete without an analysis of their historic journey that is characterized by a long period of oppression and segregation which impacted both white and black peoples attitude towards the other race. The fact that millions of African Americans live in poverty is hardly a random fact but is deeply rooted in the historical experience of this race. The historical experience of African Americans has already been drawn upon in detail. What merits however further analysis is the consequent question that rises in regard to the future. If slavery and the long history of racism and unequal opportunities in education and work, are among the main factors in the current high rates of poverty among African Americans then what is the solution? Does this conclusion imply that African Americans are destined for poverty? Regardless of the present and continued rates of poverty and inequality, it is undeniable to note that African Americans went through different stages of progress that were not as successful or as fast as desired at all times but made the necessary advancement that enabled the country to be led by a black president for the first time in the countrys history. What was essential to the assurance of advancement was persistence and endurance, two characteristics of the African American long struggle for rights as freedom, dignity, respect and equality. The period from 1976 until the present marked the growing representation of African Americans in politics, arts and entertainment and academic disciplines among others. The larger opportunities enabled African Americans to be elected to legislative positions and work in the executive and judicial branch. This does clearly not mean that the situation is ideal in the present. Regardless of the election of the first black president and the in creasing influence of this race in the United States, full equality is still a subject of heated debate and controversy. As noted, many African Americans continue to live in poverty and the ruling elite of the US is still predominantly white. While school segregation is officially over, facts point to the dominance of the continuance of the phenomenon in several public white schools where the presentation of white student exceeds 99%. (essay-911.com) However, regardless of these points that affirm the need for more progress despite the positive accomplishments obtained, the fact is that African Americans have endured a long history of oppression, pain and segregation and managed to rise above the many challenges to their current position. While the present situation requires progress advancement has been and will continue to be made while racial tension will continue to decrease. Affirming that the black race is destined for poverty seems therefore to be an implausible and pessimist ic outlook on the future and history alike. In conclusion, the history of African Americans has thus been long and complex in the United States. It is this experience that led to the formation of the present African American identity with all that that encompasses in terms of culture, art and literature. As mentioned before, blacks were largely denied opportunities for education and personal advancement until after the Civil Rights Movement. The fact that many blacks live still in poverty does however not mean that this movement was unsuccessful or that no advancement has been achieved. Continuous social change needs to be still made since the rates of unemployment among blacks compared to whites is relatively the same as it was in the early 1960s. Employment opportunities are still hard to obtain for black men while neighborhood segregation is still present in many areas in the United States. Research confirms also that blacks continue to be victims in the real estate market. (Friedlander) This all proves that blacks are stil l socially disadvantaged. However, as has been noted, racial segregation in public has been ended and more African Americans have come to contribute in elective politics signifying the slow but existent rise of this race from the dark impacts of slavery.

Chemestry Assessed Practical :: Papers

Chemestry Assessed Practical Variables: The variables for this practical are: 1. The metal that it used- magnesium, copper or iron. 2. The amount of metal that is used- any amount as long as it is divisible by 0.5 grams. 3. The concentration of the solution of the solution- molarity 0.1M or 0.5M. I am going to change the amount of metal. Fair Test: To make this a fair test I must keep everything constant except the variable (the amount of metal). But even the variable must be changed at a consistent rate (going up in 0.5g). Method Apparatus List:  · Copper Sulfate solution (0.5M).  · Powdered magnesium (15g in total).  · 2x Beaker.  · Measuring cylinder.  · Safety goggles. Measurements: I am going to use 50cm ³ of copper sulfate and then us the following measurements of powdered magnesium 0.5g, 1.0g, 1.5g, 2.0g, and 2.5g. =================================================================== Safety: I will wear safety goggles throughout the experiment, I will be careful when I pour the solution and when I am shaking it I will shake it gently. Equations: [IMAGE]Magnesium + Copper Magnesium + Copper Sulfate Sulfate [IMAGE]Mg + CuSO4 MgSO4 + Cu Method: I will measure out 50cm ³ of copper sulfate solution (0.5M) in a measuring cylinder then add it to a polystyrene cup, as polystyrene is a bad conductor of heat. Before I add the magnesium I will wait until the copper sulfate solution is at a consistent temperature and take and record the start temperature. I will then add the desired amount of magnesium (as it already weighed out for me) to the copper sulfate solution. I will observe what happens and measure the temperature change from the start to 1 minute and to 2 minutes. I will repeat this twice and then work out an average temperature change for each separate amount of powdered magnesium. If I get a result that is completely different to the other one then I will record this as a Chemestry Assessed Practical :: Papers Chemestry Assessed Practical Variables: The variables for this practical are: 1.
