Indians Immigrating To America Essays - Free Essays, Term Papers

Indians Immigrating To America Essays - Free Essays, Term Papers Indians Immigrating To America Their homeland has the second largest population in the world, yet in America they form one of our smallest minorities. Americans were influenced by their beliefs long before the first immigrants arrived, and an important interchange of ideas has continued to the present day. Although many came to America as early as the turn of the century, they were denied citizenship until a congressional act granted it in 1946. Now they are students and teachers in our universities; they are artists and writers, musicians and scientists. Their contributions to industry, commerce, and agriculture have been valuable to America and to the world. Who are these people? They are the East Indians in America. Asian Indians have supplied innumerable contributions to the culture and well being of the United States; the majority of these contributions are geared notably to engineering and the sciences. The reason for immigration in the period from 1830-1890 is quite clear. India was in a great shape. Howeve r when the British took over India, they depleted the country of all her wealth and gave her poor citizens no choice but to leave. The main reason why everybody wants to go to the United States is because if they would go somewhere else, like France or Japan although they would get higher wages, there is much greater chance of getting harassed, arrested or deported in those countries as opposed to the United States (Takai 32). Here in the United States land remained plentiful and cheap. Jobs were abundant and labor was scarce. The United States, in the nineteenth century, remained a strong magnet to immigrants, with offers of jobs and land for farms (Hess 12). The Jews came for religious freedom, Italians and Asians came for work, and the Russians came to escape persecution. America had jobs and religious freedom. Consequently, America was referred to in many countries as the Land of Opportunity. This is land is also often called the melting Pot of the World. This is because it is b elieved that people from all over the world come to the United States and loose their cultural identity and 'melt' into or assimilate into the American culture. However, nowadays, the above is an unfair statement to make. Nowadays with the growing Chinese restaurants, Indian grocery stores, and European languages is school, etc., one can say that individual cultures are trying hard to voice their distinction amongst the overall American culture. One can therefore refer to the United States as the Salad Bowl of the World where every culture has its own flavor, just like in a salad, where every vegetable has its own taste even though it has a common dressing, the American culture. Amongst the Chinese, Japanese, Europeans, etc. and other immigrants, the East Indians represented a big group of those people who wanted to be part of the American culture. The East Indians, who came to America, were mostly spread out in little groups up and down the West Coast (Pavri 56). Their story is an especially important part of the history of Asian Americans, for they were a new kind of immigrant. The large majorities of the first immigrants from India were Punjabis, from a region called the Punjab. Most of these immigrants were young men, between 16 and 35 years old (Daniels 33). Many of them were married; however, they did not bring their wives across the sea with them. Their family and community ties remained strong after they left home; they came to America in small groups of cousins and village neighbors, and these relationships formed a network of interconnections among them in the new country as they lived and worked together. They had many reasons for leaving their homeland. They were being repressed by the British rule and had no land to farm on. To make matters worse, famine devastated India from 1899 to 1902. Thus, large-scale immigration began in 1906, when six hundred Asians applied to enter the United States (Millis 32). These families became the basis for the new East Indian communities. They had come to the United States with high hopes, expecting to make their fortunes, but they discovered that life in America was unexpectedly challenging.

Collaborative Model of Criminal Justice Essay Example | Topics and Well Written Essays - 4000 words

Collaborative Model of Criminal Justice - Essay Example Interest in the field hastened in the 20th century with the universal establishment of police force, crime management and control. According to Hirsch and Gottfredson (1990), the study of crime has evolved from being a corollary or application of social science into being a distinct field with the recognition of the impact of crime and victimization to society as well as in consideration of its operation as a social institution in ensuring peace, order and stability. However, the premise that crime as a social construct and individual criminality is not at question, has not been absolute or indistinguishable amongst criminological theories. As Estrada (2004) points out, perspectives have changed significantly over time, as indicated by changes in policies. The need to understand the similarities and contradictions is not so much to establish distinctions between sets of theories but rather to develop insights on the modes or perceptions regarding crime, society and individuals over t ime. Before the 20th century the prevailing theories on crime considered individualistic perspective on the development of crime. The motivation to commit criminal acts was considered to be due to the perceived rewards or gains of the acts. In such a setting, the offender actively and deliberately chooses to commit the crime to fulfill a personal desire, derive reward or to pursue an interest. One of the challenges of such a perspective is that there is limited consideration for the development of criminal behaviors or the factors that contribute to their prevalence or the means preempting crime beyond control measures. Shedler and Westen (2004) believe that there the current perspective on crime, particularly regarding its sociological development still need retooling to accommodate personalities that do not comply with models. One aspect that they refer to is that though there is recognition of conscious and unconscious mind of an individual as well as collective consciousness with the development of psychoanalytic perspectives, there is till a significant reliance on models or archetypes. This in turn may limit cultural or social sensitivity which is a critic cal component of crime as a social construct. Similarly, there are some studies indicating that though general personality theories utilizing psychoanalysis may be sufficient for assessment purposes, they may not provide the same level of insights for the development of interventions or therapy (Jackson, 2004). The sociological study of crime developed in the 1940's. Influenced by Freudian psychoanalysis and psychoanalysis, the proposition was that individuals are influenced by their social experience and thus, their desires and motivations can be linked to social developments and issues (Plotnik, 2005). In sociological approaches in the criminology, the perception is that crime is not just individually motivated, going beyond personal choice, motivations, desires or rewards (Brown, 2003). It also diminishes the significance of biological characteristics as precursors of crime. As strange as it may seem based on contemporary knowledge, a number of studies prior to the development of organized police in Europe were conducted to compile physical characteristics of offenders, one of the earliest efforts in profiling (Plotnik, 2005; Oberwittler & Hfer, 2005). Furthermore,

Catholic Wedding Essay Example | Topics and Well Written Essays - 1000 words

Catholic Wedding - Essay Example According to the study being considered the oldest Catholic Church in Victoria, St. Francis’ Church humbly stands as an example of grandeur. It has a simple faà §ade but its structure alone overwhelms visitors from all walks of life. When one enters this solemn edifice, any person would be struck by the intricate design and the colorful mosaic of glass etching with vivid illustrations of the first family and saints where the Blessed Sacrament is enthroned. The altar is viewed in simplicity with the crucifix void of designs exemplifying the life that Jesus lived. The rationale might be to prevent churchgoers into being distracted by elaborate designs and colors. It is strategically located at a corner lot for easy accessibility. From this paper it is clear that the ritual identified here is the order of the marriage ceremony including the symbols used. It was fortunate to be accorded the opportunity to observe a wedding of couples who appear to be of Asian descent probably from the Philippines. The St. Francis Church is home to the Filipino community where a special mass schedule has been earmarked every second Sunday of each month at precisely 2:30pm. The groom wore a traditional Filipino â€Å"barong Tagalog†, made from a cloth known as the jusi fabric woven from banana or abacca plants. He stood on the altar patiently waiting for his bride.  

Identify and describe 4 additional items that can be added to improve Assignment

Identify and describe 4 additional items that can be added to improve the STEP criteria for assessment of SOCIAL,ECONOMIC,ENVIRONMENTAL,impacts - Assignment Example Apart from the internal green team, which oversees the institutions sustainability initiatives (David,2011), the company should establish external independent evaluators who will constantly inform the management on the progress towards achievement of sustainability activities and strategies. The business entity should have a written service delivery charter, which shows the standards of service delivery which the business pledges to the community especially for offsite tourism activities. This should supplement the business code of conduct as indicated in the STEP criteria(Patterson, 2005). This is a good framework for a sustainable business development as it provides a criterion for both the business its customers and the community to evaluate the performance of the business. There should be a well set communication plan which indicates the mechanism through which the entity cascades its sustainability plan to the community. Chief among them is through the organization of a get together of the business management, employees and stakeholders. As such, the business should come up with a plan showing how often such activities will be held and consequently adhere to its plan. This can be evaluated by ascertaining the existence of such a plan at the time of evaluation. To ensure that there is proper monitoring of the sustainability plan, the business should formulate the policy or strategy implementation matrix. The matrix should indicate the employees and stakeholders involved in its implementation, and the time frame and resources required. In addition, it should indicate the economic implication to all stakeholders involved. This is vital in ensuring that the local community can ascertain their benefit if they assist in achievement of entities objectives. The existing STEP criterion indicates that the company should indicate the volume of garbage it recycles. However, it is important for the

History of the River Nile

History of the River Nile The Nile River At over 4,100 miles long, the Nile River is the largest river in the world. It is located in the northwestern part of Africa. The Nile River flows through many African countries. These countries include Egypt, Sudan, Ethiopia, Uganda, and Burundi. The White and Blue Nile are two extensive channels that feed into the Nile River. The Nile River runs north into the Mediterranean Sea. The Nile River had a major impact on Ancient Egypt and Ancient Egyptians. Around the same time, every year, the Nile would flood. The flooding would happen between June and September. There are two reasons people believed why. One reason was the snow and summer rain would overflow the river. Another reason, or theory consisted of the goddess Isis. Ancient Egyptians believed the Nile would flood because she would cry so much over the death of her husband, Osiris. Out of these two theories, back in Ancient Egypt the most believed one was the snow and summer rain theory. As a result of the flooding, the Nile River provided many sources for the Ancient Egyptians. One of these sources included fertile soil. The soil around the Nile River was very rich, therefore it was good for farmlands. Papyrus, wheat, and flax were the three main crops grown from this rich soil. These weren’t only the main crops, but they were the most important crops grown. The papyrus was used to make sandals, ropes, baskets and paper. Wheat was used for making bread; the flax was used for linen cloth, which was used for clothes. As a result of the rich soil, and the growing of the three crops, the Ancient Egyptians were able to make a living. The Nile was also good for building materials. The flooding of the river provided a black silt. This black mud was used for building homes. The silt was used for many purposes especially for building purposes like walls. The Nile River was also used for transportation. Ancient Egyptians used this a major tradeplace. They used the river for transporting goods and people. The Nile River has three of its own seasons. The first season, which was the season of the flooding was named Akhet. The second season, Peret, which was for growing their crops. Finally, the last season, Shemu, was for harvesting. Each season has it own special purpose, just like the seasons we have today. The calendars that the Ancient Egyptians used were created around these three seasons. The Ancient Egyptians divided the calendars they used up into these three seasons. The Ancient Egyptians divided the calendars they used up into these three seasons. In ancient Egypt there was a god for just about everything. Hapi was the god for the Nile River. Hapi was often depicted with women breasts and a bulging belly, even though Hapi was a male. The breasts and belly portrayed fertility, the ability to produce young. That contradicts with with his capability to sustain the land around the Nile when the flooding happened every year. Hapi was also depicted as wearing papyrus plants, which I mentioned before was used a lot around the Nile River. Since the Egyptians believed that Hapi the god of the Nile they would often thank him for the flooding that happened because it provided them with many useful things. As I have mentioned before, the White Nile is one of the two extensive channels that came from the Nile River. The White Nile was larger than the Blue Nile. The White Nile comes from Lake Victoria. Since the White Nile had a longer way to travel it only gave 15% of it’s water to the Nile River. The White Nile gets its name from the color of it. It has a whitish-gray color. The White Nile has this color because of the things that travel throughout it, such as the gray color of sediment that flows with the White Nile. The second extensive channel that comes from the Nile River us the Blue Nile. The Blue Nile originates from Lake Tana, which is found in the highlands of Ethiopia. The Blue and White Nile eventually meet to form the Nile River. Just like the White Nile, the Blue Nile gets its name from its color. The Blue Nile is originally bright blue color. Since the Blue Nile passes through Sudan it picks up sediments as it travels, so the color goes from bright blue to a darker shade of blue. Even though the Blue Nile is smaller than the White Nile it carries 66% of water that flows into the Nile River. Many animals lived in and around the Nile River. Crocodiles were one of the many animals the lived in the Nile River. Birds such as heron, cranes, ibises, ducks, and geese lived around the Nile River. One animal, that many people feared, was the hippopotamus. The hippopotamus was the most powerful animal around the Nile River. Many frogs, fish, and lizards lived in the water. Gazelles, camels, donkeys, cattle, and sheep are some of the animals that lived on the land around the Nile. Today the Nile River isn’t much different that what is was like in ancient Egypt. The land is still a little desolate. The Nile may make up about only 5% of Egypt’s land, but over 95% of the population in Egypt lives around the Nile. Just as it was in Ancient Egypt, the Nile River is still lifeblood of the country. The Nile River is now under control with the flooding. The Aswan Dam helps control the flooding. The winter snow and summer is still the main cause for the Nile’s flooding. Citrus fruits, wheat, sugarcane, and cotton are some of the many crops that farmers grow around the Nile River. Many of the same animals still live in and around the Nile River today. Crocodiles and the birds are some of the animals that live in the Nile. Today, the hippopotamus still lives near the Nile River. Also, the Nile River is used for many things. Hydroelectricity is one of the many things. Dams were built to help generate hydroelectric power; these dams also help with the Nile’s annual flooding.

Dioxin and The Times Beach Evacuation :: Nature Place Essays

Dioxin and The Times Beach Evacuation The Jingle Bells of 1982 did not bring in a merry Christmas for the residents of Times Beach, Missouri, a small town of some 1400 people. During the annual town Christmas dinner the residents finally received the news that they had hoped would never come. The residents of Times Beach were to be relocated and the town were to be bought out by the federal government. This was the first time such a thing was done since the founding of the nation. The buyout of Times Beach and some 50 other sites in Missouri by the government beginning in 1983 was prompted by the largest civilian exposure to dioxin in the United States. Dioxin is a member of the family of organic compounds known as aromatics. Dioxin is the shorthand that refers to a family of polychlorinated dibezodioxins or PCDDs. Their general structure is that of two chlorinated benzene rings joined by two oxygens, hence dioxin. Dioxin is not made intentionally but are usually formed as by-products in many large scale chemical processes such as paper pulp bleaching with chlorine and most significantly, the manufacture of chlorophenol chemicals. This last process is significant not only because it brought dioxin the current notoriety but it also is a chemical process used to make products that were used and are still been used in many applications. These applications include pesticide, herbicide, defoliating agent such as Agent Orange, cleaning agent and electrical insulation. Consequently, human exposure to dioxin is not a recent phenomenon and the dangers of dioxin are not unknown. Only in recent years, especially after the Vietnam War, has the media concentrated on the dangers and impact of dioxin. The physical effect of exposure to dioxin was first seen in skin diseases developed by chemical plant workers in 1895. The exposure to dioxin results in a type of skin disease like acne called "chloroacne," since its cause was initially and incorrectly linked to chlorine gas. In 1957, in Germany, Dr. Karl Schulz of the University of Hamburg identified chloroacne in several workers from a Boehringer chemical plant. The disease in its mildest form resembles teen-age acne but differs in that the blackheads and cyst cluster in two locations: appearing in a crescent shape outside of and under the eyes and ears. In more pronounced cases, pus-containing spots erupt and spread across the rest of the face, neck, shoulder and down to the rest of the body.
