Conflicts in an American Family in play A Raisin in the Sun by Lorraine Hansberry The play â€Å"A Raisin in the Sun† illustrates three main conflicts in the younger family life; they are internal, social, and interpersonal. The conflicts in the story give insight as to who the characters are and what they really want out of life. Conflict is one of the underlying themes in the play, which was written by Lorraine Hansberry, it helps to tell the story and explain the situation that the Younger family is in. The characters in this story were African American, but they could have been from any ethnic group because the problems that they have to face apply to us all. Ossie Davis said it best when he said the â€Å" it didn’t really have to be about†¦show more content†¦Beneatha feels that by becoming a doctor she will have a new life (Cheney, 58). However like everything else in this play there are obstacles to overcome. The biggest obstacle is the fact that she is a black woman. In the sixties woman in general were treated unequally much less a black woman. The second obstacle is her brothers Walter â€Å"†¦ go be a nurse like other woman† (Hansberry 1.1 1019). Walter is very much opposed to his sister’s education because of the fact that he wants to use the money to fund his dream. Characters in the play, aside from fighting with each other also have to deal with their own internal struggles. The best example of this sort of internal conflict is Ruth. Ruth is pregnant and does not know what to do. She wants to get an abortion to prevent putting any more strain on the family (Cheney, 61). She also feels that by having a baby it could put more pressure on Walter and instead of him wanting to sell liquor he will start to consume it and destroy his life. Lena is another one of the characters that faces an internal conflict. Her conflict is with the money. She has full control of the check and has already used part of it for a down payment on the house she bought. The other part of the check is where her d ilemma lies. She wants to see Beneatha go to medical school, but at the same time she sees how desperate Walter is. Reluctantly she hands over control of the money to her son.

Memories of Life Before Government Control Orwells 1984,...

Overbearing governments can change every aspect of society but people’s memories and their stories of the past cannot be completely altered to forget what life was like. Society uses these memoires to compare it to the new way of ruling which sometimes is less favorable to the individual. Governments try to change people’s opinions of reality which proves to be impossible. Within the novels, 1984 by George Orwell, The Handmaids Tale by Margaret Atwood and Brave New World by Aldous Huxley the Governments have taken societys freedom away and all that remains are the memories of what life was like before the changes; the main characters are constantly using the past as a way to survive through the difficult times.

The common citizens do not even notice when history is altered right before their eyes. During a protest the country of interest changes from Eurasia to Eastasia. The change is seamlessly made as the crowed does not even flinch. Winston notices and tries to convince Julia, his lover that the war was really with Eurasia and not Eastasia. He argued with her about it for perhaps a quarter of an hour. In the end he succeeded in forcing her memory back until she did dimly recall that at one time Eastasia and not Eurasia had been the enemy. But the issue still struck her as unimportant(Orwell 154). This issue was so important to Winston because he wanted to spread his knowledge of the lies of Big Brother. He believed if people could just remember what life was like before Big Brother there was still hope of overthrowing the government. Winston knew, When memory failed and written records were falsified—when that happened, the claim of the Party to have improved the conditions of hu man life had got to be accepted, because there did not exist, and never again could exist, any standard against which it could be tested. (Orwell) A persons memory of better times gives hope that things will return to the way they used to be. Offred, the main character in The Handmaids Tale, is constantly

Financial Management for Merchandise and Equipment- myassignmenthelp

Question: Discuss about theFinancial Management for Merchandise and Equipment. Answer: Introduction Financial management in a nonprofit organization is significant to effectively run the business operation. It is identified that the main goal of profit organization is to earn a profit and increase the value of their shareholders. But, the main purpose of the non-profit organization is to facilitate the socially desirable requirement on an enduring basis. In current business practices, profit organization depends on exchange transaction between businesses and B2C. However, the non-profit organization depends on the money that is donated with a specific intention (Hudson, 2017).This essay discusses the financial management difference between nonprofit and profit organization. It also presents the role of Financial Management in not- for profit organizations. Role of Financial Management in Not- For Profit Organizations According to the Finkler et al. (2016), financial management is essential for both profit and non-profit organization. A non-profit organization must demonstrate the activities regarding donating resources. The workforces of the organization could be able to demonstrate their expenses activities by assessing the financial records. Furthermore, two essential areas of financial management play important role for not-for-profit organization named budgeting and cash management. Therefore, these companies focus on the utilization of reserved cash. It can be stated that estimation of cash flow is challenging for the organization because the organization heavily depends on the resource providers. In support to this, Renz (2016) evaluated that management and protection of financial resources are essential for the not-for-profit organization because, without adequate resources, the company may not attain its mission and survive in the industry. Financial resources comprise goods and services, and money. Money includes the checking, securities, investment, cash and savings that organization has required to run its business operation. Goods contain the supplies, merchandise, and equipment. Services are the program and activities which are delivered to the customers. These resources could be managed by financial management because it will decline the risks related to business. Furthermore, it will enhance the value and gain the financial resources. Bryce (2017) discussed that financial management plays important to manage the asset in the nonprofit organization. Therefore, it is essential for an organization that it should have adequate assets to fund their existing operations. They have to be competent to make stability between available and growing resources. Moreover, not for profit organization should be able to pay debts in a well-timed manner, and should accomplish other financial obligation. After creating the budget, a company can pay attention on financing the existing operation and gain resources to increase their return on capital and assets. Assets management is also required to maximize the resources. It also manages the cash inflows and outflows which help the not for profit organization to provide more benefits to communities. Consequently, it will gain significance of budgeting because the nonprofit organization would be able to attain the financial obligation. McKinney (2015) argued that nonprofit organization is distinguished from profit organization in a different manner. In this way, it stated that the main aim of profit organization is to increase the profits and transfer this profit to the director of the company and shareholders while the key purpose of the nonprofit organization is to fulfill the needs of societies. Together with, the nonprofit organization has no director and employees act with the purpose of increasing the revenue and minimizing the costs because it will ensure that company is providing benefits to societies. In favor to this, Maier et al. (2016) stated that profit organization pays tax on their earnings however nonprofit organization does not pay taxes due to not getting profit. Government helps the non-profit organization to minimize their costs because the key intention of this organization is to act with respect to the welfare of the society. Moreover, there are two kinds of organization that affected each kind of accounting practices. In case, tax exempted nonprofit organization submits their financial statement to IRS then it will only assess the sales tax and real estate tax. Arvidson and Lyon (2014) argued that financial management plays important role in appropriate managing the funds. Hence, the non-profit organization has to pay attention to the mission of the company. Further, it should monitor the progress of the company and also focuses on how capitals are being used. There are different restriction and limits that must be followed by the company during managing the funds. Since, the inappropriate use of funds can cause an extraction of money, having to reimburse the money and not getting a future return. Another cause is a loss of exempted tax and other legal problems. In support to this, Chikoto and Neely (2014) opined that a budget is an operating plan for the company. Hence, the decision regarding accomplishing the mission of the company is made by staff and board members. They have to choose the agenda that will create positive effects and then assign the resources as per the plan. The budget facilitates the steps to staffs to achieve their objectives. The budget also enables the nonprofit organization to assess how funds will be assigned and how to make optimum utilization of resources. It also helps to address the potential financial issues of the business in future. Conclusion From the above discussion, it can be concluded that financial management is beneficial for a non-profit organization to manage the finances on daily basis. Further, it enables the company to assess where donated resources are invested. It can be also summarized that there are two essential areas of financial management that are to be focused on the nonprofit organization named cash management and budgeting. Along with this, it can be evaluated that fund and asset management is significant for the nonprofit organization because it enables the company to distinguish the donated money by time and intention. Not for profit organization should do a self-assessment to evaluate the companys position because it will help to make continuous growth. References Arvidson, M., Lyon, F. (2014).
