The Life of a Woman Plantation Slave essays
The Life of a Woman Plantation Slave essays The life of a typical woman plantation slave was one that is somewhat troubling to think about. These women were forced to leave their homes and their families to become the property of a plantation owner who, for the rest of their lives, dictated what these women were to do. These women had to adjust to many different and new things. When a new slave woman arrived, she spent the majority of her time learning the native tongue, learning the new agriculture, and adjusting to the difference in the climate. (Berkin, p. 62). In learning these new things, they also had to learn to be totally submissive to their masters in body and mind or they suffered abuse and this abuse included sexual abuse as well. In order to fully understand the life of a typical woman plantation slave, it is important to know where she came from, the type of work she does, what her relationships are, and how she copes with her lifestyle. In the late seventeenth century, the importation of Africans from the coastal regions of Africa begins. (Evans p. 27) This proves to be an asset for plantation owners as African women were known for their abilities in agriculture and, therefore, their expertise at planting and cultivating could be put to use to produce huge crops for the plantation. Men and women were both put to work in the fields at the discretion of their masters. Their workdays were very long going from sunup to well into the evening hours. Early on men and women on the plantation did the same types of work which usually included planting and harvesting by hand. Later on when plantation owners began using the plow instead of the hoe, the men were responsible for doing the more skilled labor such as plowing and the women were left in the fields to hoe what could not be done with the plow or to transport harvested grain from the fields to the barns on their backs. (Berkin, p. 62) Women did not only work in the fields though. S...

This i believe essay Example | Topics and Well Written Essays - 500 words
This i believe - Essay Example Friendship is a form of love that people share and comes along through common interests where friends enjoy what they do and share and interact regularly. Moreover, having gone through the same experiences in life ties people together and sharing values makes friendship to be stronger. Furthermore, true friendship is the will to put happiness before friendship and telling of something that one does not want to hear. A true friend inspires, motivates, and encourages an individual to live up to their best potential. They always have the best interests of their friends in their hearts and are always available when one is down. In addition, they laugh with their friends in times of happiness and in times of sorrow they comfort and cry with them. For the longest time I relied on friends for company and affection. Truth be told, I was happy about that and regarded myself as the luckiest person in the world. Somehow, I often felt that I was not giving my best to one of my good friends. This kept me thinking since my friendship experiences were different from the way it is portrayed culturally. One of my true friends was a drug addict and it was so scary since she could not survive without drugs. This is something that people, especially the parents and close relatives did not know. It was difficult to pass such kind of information to the parents and relatives, as it is not acceptable in the society to abuse drugs. As a friend, I knew I had a big challenge of helping my friend and keeping her on the right track. One day, we had a chat and I knew it was my responsibility to help her get out of the huge problem she was in. She was hesitant at first and asked that I should not tell. I told her I was not going to, but I was going t o help. I advised that she should see a counselor who would guide on how to stop using the drugs. I supported her financially and emotionally and even helped her look for a counselor. It was not easy, but after all, I was happy since I knew she

Critically examine the characteristics,tactics, opponents and policy Essay
Critically examine the characteristics,tactics, opponents and policy impact of the NRA(National Riffle Assoc) - interest group operating in the USA today - Essay Example These include army officers, police officers and sheriffs while they also participate in occasions meant to compete in shooting skills. The organization has set programs meant to keep off violent criminalsââ¬â¢ incorporation with the law. These programs include CrimeStrike that was introduced in order to eliminate gangs and other unwanted people from the streets of America and be convicted as per the crimes they commit. The other program introduced is the Eddie Eagle meant for children that creates public awareness on the importance of observing the laws stipulated against possession of guns and how to protect one self. This program gives warnings such as Stop or Donââ¬â¢t Touch signs put at places where these guns are kept in the house. Other programs educate adults such as skilled hunters, shooters and people who possess ammunition for the sake of their safety such as security gourds. Most foreigners have been surprised by the way most Americans prefer to own guns. Antagonists view the Second Amendment as stated by the constitution on the ownership of guns as a cause for the problem. The statement reads that as well as a military officer lawfully allowed to posses a gun, then owning guns has to be a right to all and must not be prohibited. There have been recent debates on ways of controlling guns to the public but this has brought no change in US we daily find shooting cases on the media. This evidence shows that there is a very strong correlation between violence and accessibility of ammunitions. Some federal laws initiated in 1970s due to the assassinations of high people in government for instance Martin Luther King. Later other policies were also set up as a result of several assassination cases. It is for these reasons that Brandy Bill has to take time while issuing out guns to the public.

A research on the issues of the black urban experience according to steven gregory Essay Example for Free
A research on the issues of the black urban experience according to steven gregory Essay Critical Reading Assignment #3 Chapter 5: Race and the Politics of Place Gregory, Steven (1999) Chapter 5: Race and the Politics of Place, in Black Corona, Princeton, NJ:à à à à à à à à à à à à à à Princeton University Press, 109-138. The researchers conducted this study in order to challenge the depictions of the black urban experience in the media, academics, and public policy debates, which the author does frequently throughout the study. In this portion of the study, Gregory focuses on the struggles that black Lefrak City residents to disrupt the lingering stereotypes alluding to race, crime, and space in everyday politics. To conduct this research, Steven Gregory, an anthropologist, uses ethnography methods including open-ended interviews, participant observation in neighborhoods and political meetings, and archival research to collect the data used in this study. He interviews various residents and political members from this area and attends a meeting involving the Neighborhood Stabilization Committee and Community Board 4. The study takes place in the Corona neighborhood of Queens, New York, specifically in the Lefrak City are home to many African Americans residents as well as people from many other backgrounds. In this study, Gregory points out the struggles that Black Lefrak City residents had in disrupting the lingering stereotypes about, race, crime, and space in everyday politics. He explains how this area of Corona was viewed as a threat to the quality of life in the surrounding areas, which provides a link to urban decline and crime to black welfare dependency (Gregory 111: 1999). He focuses on struggles in the representation of identity and the meaning of place with the distribution of political power. As evidence, Gregory interviews and observes Edna Baskin, an African American woman eager to get involved and create a political organization to counteract these stereotypes and give black citizens from this area representation in the local politics. She establishes the organization called the Concerned Community Adults, where she would help inform residents of neighborhood issues. She faced many struggles in doing this, however, and was said to be ââ¬Å"rubbing against the grainâ⬠(Gregory 118: 1999) while trying to promote her organization and get involved with the Community Board, made up of mostly white participants. Gregory talks about other problems this organizations faced, and the successes it achieved later on. This research has strengths in its overall comprehensiveness of the issues that Gregory is discussing. The topic he tries to tackle is very complex, and he does a good job at trying to try to explain the overall issues of the research. However, Gregory could organize his work in a fashion that is easier to comprehend that helps understand the overall concepts and issues he is focusing on in the research. He also only discusses in depth one example of the struggles that one area of this community faces. I believe that it would be interesting to instead compare the many different struggles that different areas of the community have and relate them to one another. It would be interesting to see the similarities and the differences between the different areas of this community.

Tales of glorious victories, conquering heroes, and vanquished foes color our perception of this legendary city.? Myth and reality are so closely intertwined that we would be remiss to examine the one without the other.?

Umass Dartmouth Reflection
I am currently on year six at Umass Dartmouth, and thus far it has been quite the journey. I have been a commuter for all six years and my experience hasn't been too enjoyable. If I could restart my college experience I am not sure if I would not even put this school as a possibility. I have experienced some positive experiences at this school, but the negative aspects definitely outweigh the positive. However, this current semester has really changed my view on the University. Umass Dartmouth's campus is definitely unique.One thing that has always bothered me about Umass Dartmouth is the look of the buildings. The outside and inside of the buildings definitely help to impact the negative feeling I get about the campus. The campus is so gray looking that it makes me feel somewhat ââ¬Å"gray'. The classrooms are very uncomfortable regarding seating, temperature, and desk space. One positive aspect of the campus is the layout. Personally as a commuter student I really like the ââ¬Å" ring roadâ⬠effect. I feel it makes the campus really navigable.A big negative when I think about Umass Dartmouth is how I feel as though a large majority of the staff does not care about the students. I have had many experiences ith different departments of the school being very rude to me in different situations. I feel as though the advisors at least should be interested in your wellbeing at this school, but even with most advisors I have had awful experiences. I have switched majors a few times so I have experienced many different advisors.Not every employee of the university has given me a negative experience. I have had a few professors who I felt were very dedicated to making sure I was learning and understanding the material. This is an aspect that I feel is very important, so I am rateful to have had the experience to be taught by some very educated, caring professors. The core business classes that I started taking as an operations management manger were a very good b ase to my major. The classes really helped to give me a broad understanding of different business areas.The class sizes for these classes were medium sized which I thought was perfect for these types of classes. Most of the professors I had for these classes I felt taught me the material very well. However, I did come across one or two professors that I feel really did not benefit me at all. I really find it unfortunate there are professors in this university who do not teach the material well at all. At the end of a semester looking back at a class and feeling like I can take close to nothing from it really frustrates me.I feel as though the university should really be monitoring the classes and spectating them. So far the operations management major required classes have been very good. The sizes of the classes are perfect. I have found all my classes very interesting, and felt the material is being taught very efficiently. I have learned more this semester than any other semester at Umass Dartmouth. One thing that I really have enjoyed this semester is the amount of class interaction. I have experienced a lot of class discussions and have done a lot of presentations.I absolutely hated presentations at much more confident in giving presentations and participating in class discussions. Another part of this semester I have enjoyed regarding my major required classes was a recent trip I took toa manufacturing plant that one of my professors setup. I felt this was extremely beneficial. Being able to actually go toa real life plant and see concepts being used in real life really opened my eyes, and made me really excited to raduate and start my career to apply concepts I have learned.My experience at Umass Dartmouth started out negative, but as I continued through it seemed to start to improve. This current semester has really impacted me positively. I feel as though these operations management courses are really starting to prepare me very well for my career. I really feel as though Umass Dartmouth's campus is a very big negative for myself as well as for other students. If they Just added a little more color to every building it would really help to improve the atmosphere!

simuulation games essays
simuulation games essays Simulation Games- To take the appearance or form of; to pretend; to make a model of Simulation games have come a long since they first began a long time ago. Graphics and sound have gotten much better, complexity of the game engine and multiplayer capabilities have also made great leaps. People still wonder if it has actually gotten better or had just changed. Now, 3-D cards and huge program files have become the standard to run the simpler Sims. Since simulation games try to accurately represent or mimic real life situations technology will continue to make them better until we no longer separate fiction from reality. When simulation games first came out they were not that big amongst kids. Though they would try and sneak off into a computer lab and try to play as much as they could. When flight simulation games came out kids were amazed at the fact that they could fly around the sky and have it feel like that they are actually in the plane. The game that really turned games around for the future was SimCity. To build an entire city was a new revolution for what games could be. Today the market of simulation games continues to spread really rapidly. Developers of games seem to come up with new ideas daily. SimCity has advanced the whole gaming market. There have been more islands, towers, colonies, and life built. There has been SimCity 3000 and now they are working on SimCity 4000, which should be released by the year 2000. Other games such as helicopter games have also come along way and are rising rapidly. Gunship launched a lot of helicopter games including its latest version Apache Havoc. This gives the option to fly either American or Russian Choppers. Soon Gunship 3 will come out and Apache Havoc will be just another old game. What we see in the future is very amazing, technology is going to continue to grow and everything is going to become much faster. ...

Catcher in the Rye Symbols Essays
Catcher in the Rye Symbols Essays Catcher in the Rye Symbols Paper Catcher in the Rye Symbols Paper Essay Topic: The Catcher in the Rye Pencey Prep: Pencey Prep is a boarding school for boys located in Agerstown, Pennsylvania that Holden was attending at the beginning of the novel. It is the fourth school Holden has attended and is later the fourth school he is kicked out of because of his poor marks. Pencey Prep is where the reader is able to get their first glance of Holdens lonesome character, strong opinion of phonies and the fact that he does not apply himself as he fails four out of five classes. At Pencey Prep, the theme of ââ¬Å"alienation as a form of self protectionâ⬠arises as it becomes clear that Holden can not maintain a close relationship with anybody. Holdens alienation and distance towards others is made clear after he agrees to write an English composition for his roommate, Stradlater. The composition is about a baseball glove that used to belong to his younger brother, Allie who died from leukemia when Holden was only thirteen. After the death Holden never wanted to get close to another person so that he would never have to feel the pain of loosing someone he loved and cared about once again. Lastly, at Pencey Prep, we are introduced to another important character, Jane Gallagher; an old friend of Holden that is going on a date with his ââ¬Å"secret slob [and] Year Book handsomeâ⬠(27) roommate, Stradlater. Before leaving Pencey Prep Holden is too afraid to go say hi to Jane in the lobby, in case she was not the innocent, perfect girl he grew to love in the past. Allie and his Glove: Allie Caulfield is Holdens younger brother who died of leukemia while their family was in Maine on July 18, 1946. Holden was only thirteen at the time of the death and has idealized Allie ever since, describing him as the the most intellectual, admirable and humorous person you could have ever met. From Allies death, the reader is able to witness first hand Holdens ââ¬Å"madmanâ⬠characteristics. The night after the death Holden spent the night in their garage where he decided to smash all the windows, breaking his hand and earning him a night in the hospital. Claiming that he did it ââ¬Å"just for the hell of it,â⬠(39) although it is easy to see that he did it in a pit of rage over Allies death. Holden was extremely close with Allie as he represented perfectly the pure, uncorrupted innocence of a child that Holden longed for himself. To Holden, it is unfathomable why such an innocent child such as Allie had to suffer and die and that is most likely the root of Holdens problems and negativity towards phonies, growing up and losing innocence. Holdens behavior and social skills underwent a detrimental change following the death as he was no longer capable of maintaining a close relationship with anybody in fear of suffering through another loss. Allie represents the purity that Holden looks for in the world. Ducks in the Central Park Lagoon: Throughout the novel Holden continuously contemplates where the ducks from the Central Park lagoon go in the winter. They are a reoccurring thought for Holden and a major ambiguous symbol to the novel. Holden initially thinks about the ducks, wondering where they go when the lagoon freezes over in the winter while talking to Mr. Spencer after being kicked out of Pencey. At this moment the ducks become an immediate symbol of Holdens anxiety and uncertainty regarding his next move after being kicked from Pencey. Much like the ducks who are repeatedly kicked from their home at the lagoon, Holden was kicked from Pencey Prep and had no plan and no where to go. Not having a clear answer to his question, Holden continues to wonder what happens to the ducks in the winter time. Holden later asks cab driver what he thought happened to the ducks, but the cab driver disregards the question and explains that the fish have it harder as they freeze in the ice and ââ¬Å"get frozen right in one position for the whole winter,â⬠(82) and as for food, their nature is to soak up nutrients from seaweed in their pores, therefore nature takes care of them during the winter. In this case the ducks are symbolic as they represent Holden as he is being forced to move; however, Holden would much rather be like the fish who get to stay where they are and have everything provided for them like children. This mirrors the common theme of the novel and Holdens attitude towards growing up and wanting to stay an innocent child. Finally, Holden thinks about the ducks for the last time when he is drunk and decides to go look for the ducks at the lagoon. At this point, Holden is in his worst state; he is depressed, anxious and even contemplating suicide. Seeing that they are truly not at the lagoon Holden realizes that he must migrate away from his childhood and fly into adulthood. Over all Holden wants to know where the ducks go because he wants to know where to go when times are tough and things do not belong. Phoebe: Phoebe Caulfield is Holdens ââ¬Å"roller-skate skinnyâ⬠(67), red headed little sister. To Holden, Phoebe is more like a saint then a sister; describing her as the most beautiful, angelic, intelligent, mature and affectionate little girl you could ever meet. Holden also explains that she is very funny and has a good sense of humor, is a great dancer, listens and always knows what you are talking about. Despite the fact that Holden admits to being ââ¬Å"THE MOST terrific liar you ever saw in your life,â⬠(16) there is no doubt that he is telling the truth about Phoebe as she is everything Holden said she would be. Phoebe is one of the few characters to truly understands Holden for who he is and the struggles he faces on a daily basis. She unconditionally loves Holden and would do anything to help Holden such as giving him her Christmas money. In the end Phoebe is exactly the kind of person Holden has been ââ¬Å"people huntingâ⬠for. He wanted to find someone to love and to love him back and was blindsided by the inevitability of growing up to see that what he was hunting for was right under his nose the whole time. sparknotes. com/lit/catcher/characters. html shmoop. com/catcher-in-the-rye/symbolism-imagery. html

Physics (Electron Physics and X-ray Tomography) - Coursework Example gher than that of the photon attraction for the jump to take place from K-shell to the L-shell, loosely bound electrons from L moves into the K-shell to replace the ejected electron. When a lot of high incident energy are directed to an atom, many electrons are emitted and forms the x-rays. Bremsstrahlung is the process of slowing down primary radiatin; X-ray is produced by radiations when electrons are retarded or decelerated2.. The radiation becomes intense and attains higher frequencies with increase in energy of bombarding electrons. The colliding electrons shifts electrons from high-energy shell to low energy shells, the rapid replacement by electrons from outer shells create a clearly defined x-ray. The curve shown below was produced by analysing the nature of radiation produced by bombarding electrons from four distinct energy levels against a tungsten target. The graph is used to relate the intensity of x-rays emitted and the wavelength for accurate x-ray photographing. The figure above shows X-ray spectrograph when copper is used as the target material, the intensity of the photon have linear relation with the wavelength. The intensity rises to peak then starts to slope downwards; high accelerating voltage causes the peak to rise sharply, as shown by Kp, KÃ ±, LP and LÃ ±. X-ray tube functions as energy converting system that converts electric energy into x-ray radiation and heat. Heat3 is the undesired product of the process; the conversion takes place in x-ray tube. The components of x-ray tube includes The higher the amount of current the higher the intensity of x-rays emitted since more of electrons are displaced from the high energy levels. In the case above, 5mA produces much lower intensity of X-rays as compared to 100mA since the rate of electron displacement is high in the first case characterized by the high peak of 100mA current4. b) Attenuation by photoelectric effect result from interaction between Photons and Matter.

ENVIROMNMENTEL ANALYSIS CASE STUDY Essay Example | Topics and Well Written Essays - 2250 words
ENVIROMNMENTEL ANALYSIS CASE STUDY - Essay Example The retail firm operates on the basis of several formats like Discount Stores, Supercenters, Neighborhood Markets and Marketside to help cater to different levels of customer needs (Walmart Corporate, 2011). The business environment of Wal-Mart like any other business firm is divided along both internal and external facets. The internal environment of the firm is governed by the family ownership of Wal-Mart being the largest stakeholders. Further, the firm works in a centralized fashion with higher management settled at Arkansas. The retail firm strategizes its internal operations with a view to reduce the operational cost and binds the workers to each other. It continually promotes research and development activities to innovate newer private label products. (Environmental Scanning, n.d.). The external environment of the firm is composed of economic, political, social and technological factors. Further being internationally spread the firm is amenable to environmental changes of the different nations and also faces global completion from a large number of retailers. (Wal-Mart Case Study, 2010). Business Environment of a Firm The business environment of a firm is composed of such factors belonging to the external side of it and would affect the present and future operations of the firm. Moreover, different business firms have different types of business environment which is thus situational in nature.
