King Lear and the Drawer Boy Comparative Essay Essay

Sometimes, unconsciously, role play is used in our daily lives to assume or act out a specific role. The role play portrayed in Shakespeare’s King Lear and Michael Healey’s The Drawer Boy is best defined as the acts or attitude of a person differing from normal in order to attain a better point of view, social interaction, or a goal. William Shakespeare, born in Stratford-upon-Avon, England in 1564, is known world-wide for his talent for writing plays and poems (William). Shakespeare’s King Lear was officially printed in 1608 (King Lear). This play follows the life of a headstrong old man, King Lear, whose mental state is disturbed by his two selfish daughters, Goneril and Regan. Lear’s other daughter, Cordelia, is loyal to her father, but is disowned for her simple, yet honest response to her father’s question in Act one. The daughters must flatter their father in order for him to decide who gets the most desirable part of his kingdom, but this only elicits lies and cruelty from Goneril and Regan, eventually leading to Cordelia’s and Lear’s downfall. Meanwhile, Gloucester, the father of Edgar and Edmund (his illegitimate son), is blinded by lies as well. Edmund manages to trick his father into disliking Edgar in order for him to take over Gloucester’s power. Michael Healey reflects on betrayal in the form of a stage play, The Drawer Boy, a story told with humour, but also about loss and love. Healey, a Canadian playwright and actor, was born on August 25, 1963 in Toronto, Ontario (Nothof). He based The Drawer Boy on a group of actors who went to farms to research rural life in Southern Ontario and collectively produce a play called The Farm Show. The Drawer Boy is a full length play that focuses on a young actor from Toronto, Miles, and his experiences while visiting a farm owned by two older men, Morgan and Angus. Morgan cares for his close friend Angus, who has brain damage and memory loss which happened during the bombing of London in the Second World War. By the end of the play, these three men create and interpret reality through storytelling and role play. It is obvious that both works use role play as an important device that helps develop the topic of deception. Although the essential nature of role play in King Lear is mostly corrupt, in contrast to the innocent intention in the Drawer Boy, both forms of deception have positive consequences. These positive consequences are what allow the characters to act morally and to understand the value of others. Everyone has an individual role that has the ability to influence other lives. Being capable of role play can have negative and positive effects, depending on how it is used. In King Lear, Edmund is described by his father as the â€Å"bastard son†, and that is the exact role he plays. This role was given to him at birth. Although Edmund is cruel and manipulative in nature, he does find a means for redemption. When Edmund is defeated by his brother Edgar, he still has the chance to kill Cordelia and King Lear, but instead, he makes an attempt to save them by calling back his soldiers before they follow orders. Although the attempt is unsuccessful, a different side of Edmund is revealed during this final act, and he admits to being out of character. â€Å"I pant for life. Some good I mean to do, despite of my own nature,† he declares (5. 3. 291-292). This self-awareness is significant because Edmund acknowledges how his role has affected others, and takes advantage of the opportunity to make a moral decision. This form of justice is also portrayed by the character Miles in The Drawer Boy. Miles’ task is to go to a farm and study how farm-life works in order to create a play about it back in Toronto. The more he gets involved with the lives of Morgan and Angus, the more intrigued he is by them. Although there are a few humorous references to farming, the main attention of this play is on Morgan and Angus’ history together. Miles decides to use the original story he overheard Morgan telling Angus one night as a part in his play. After attending Miles’ rehearsal, Morgan is not impressed by how invasive the play is, but Angus is excited by the reanimation of his life. When Miles discovers there is more to the story, such as sadness and loss, he declines Angus’ offer to use their story in his play. â€Å"Thanks. But—thanks†(Healey 188), Miles says as he hands over his notebook. Miles decides to give up the whole play, even if it means it will jeopardize his career as an actor. When Miles hands over his notebook to Morgan it symbolizes the ethical decision he is making. Even though his role in the play is to investigate farm life, he steps out of that role to do what is right. Edmund and Miles are characters that can be easily compared. They both show that a specific role is not given to someone; instead, people can determine how flexible and adaptable their role in life is. The way that Edmund and Miles adapt to their surroundings by changing characters in order to make a just decision is heartening. Valuing other people for their individuality or specific characteristics is essential to positive interaction among humans. When people take on the role of someone else they lose their individuality and worthiness of true self-value. This type of deceiving interaction is seen in both King Lear and The Drawer Boy. Lear’s flaw at the beginning of the play is that he values appearances over reality. Using role play to their advantage, Goneril and Regan are villainous and use Lear’s blindness to their true natures against him. They alter their characters to flatter their father, who is too full of pride to recognize deceit. Cordelia’s sincerity is misunderstood and Lear banishes her because she does not compliment him like her other two sisters. Both Goneril and Regan have altered their personalities to gain all of Lear’s powers, and it is not until they take everything away from Lear, that he realizes Cordelia is the only daughter who truly loves him. He begs for forgiveness as he cries to Cordelia, â€Å"If you have poison for me, I will drink it. I know you do not love me; for your sisters/ Have, as I do remember, done me wrong† (4. 7. 82-84). Although Lear believes he has done Cordelia wrong and deserves to be punished, Cordelia has no desire for revenge, or any need to make her father suffer for having misjudged her. Goneril and Regan make their father believe they are someone else, but in the end, Lear is able to made amends with Cordelia and value her compassion and honesty. Thi s family journey reinforces the idea that at the heart of every betrayal lies a skewed set of values. Similarly, Morgan values his life-time friend Angus, but does not fully appreciate him until the end of the play. Morgan hides the truth from Angus for a couple of reasons: Angus hit Sally during one of his headache episodes and that’s why she and Frances left the farm. Morgan alse wants to protect himself from his guilt over being responsible for Angus’ accident that caused the headaches and memory loss. When Miles and Angus push Morgan into finally revealing the true story, Angus is overwhelmed, but understanding. Morgan explains, â€Å"I told you the story of the black car crashing for the first time. I told it again, and you stopped crying. I told it again, and you fell asleep. I kept telling it ’cause it made you feel better. Goddamn it, it made me feel better† (Healey 187-188). By telling Angus the truth, Morgan shows how his protective role overpowered his role as a friend. He was, in a way, being selfish by hiding this secret from Angus because he felt guilty for being the one who made Angus go out to the car to get a bottle of brandy when the accident occurred. Angus, however, is not mad at Morgan, but upset with himself for hitting Sally, which caused both Sally and Frances to leave. Both men feel guilty and sorry for one another and for what they have done. Angus had the right to know the truth and Morgan realizes that after seeing how his friend handles it. Morgan now has more respect for Angus, especially after they make a promise to tell the story every day even if Angus forgets. Angus plays a unique role in this play because he is lacking memories of his past with Morgan. Even with memories missing, he still acknowledges the importance of Morgan in his life, and vice versa. The characters recognized the value of others near the end of both works. Truth comes out by the end of King Lear and The Drawer Boy that draws attention to the real role of characters. These character traits are what reveal to the audience each character’s true nature and this realization is what brings those characters closer. Although in The Drawer Boy, Morgan already valued Angus for who he is, it is not until the end of the play that he can explain why he values his friend so much. Whereas throughout King Lear, Cordelia is wretched compared to her sisters, and Lear does not realize how important she is until the very end. In conclusion, while King Lear have more sinister intentions of role play, it is easily comparable to the role play in The Drawer Boy. Characters from both works change their behaviour to accomplish tasks which lead to important results. The results are identified as the characters making moral decisions, and developing a new appreciation of others. In King Lear, the good are misjudged as evil and the evil are accepted as good. In The Drawer Boy the effect of loss and love overwhelms the reader. Two intriguing pieces of writing that are different, but similar in many ways, use an important device, role play. Role play can be as simple as a child playing â€Å"Doctor†, or it can be as serious as altering one’s entire personality to be someone else. In either instance, it is an effective tool that can have many advantages or disadvantages. How people decide to use this ability that defines them and the outcome.

Workers compensation claim Assignment Example | Topics and Well Written Essays - 750 words

Workers compensation claim - Assignment Example Employee can claim workers compensation benefits after being injured or when he or she develops a disease that is work related. Not all injuries are covered under Employee Compensation Law even after the injury â€Å"on the job. For it to be covered it must be accidental and arising in the course of carrying out work related duties. The law only protects workers. A genuine relationship between employer and employee must exist. Compensable injury claim must arise out of the employment (Jasper, 2008). Deriving support from Rensing v. Indiana State University (1993) and Coleman v. Western Michigan University (1983) cases it is clear that the student will not prevail in the case on the ground that workers compensation benefit is only available to employees. A student who is a football player who gets injured in the field cannot claim for workers compensation benefits because there is no working relationship between him and the university management. According to the employees, act the student does not meet the legal meaning of an employee. Workers Disability Compensation Act, which defines employees every person providing a service to another under contract of hire or apprenticeship, impress or implied, written or unwritten (Hotchkiss, 2003).The law is not limited to minors or aliens. The law also excludes volunteers. Student in this case is a volunteer since he is not paid any wages after playing football. The student is not regarded as an employee because he is not hired by the school to play football. For compensation to take place, the plaintiff must proof the following: that the company dictates or controls the actions of the employee, that there are rights to discipline or fire an employee. The plaintiff must also prove that payment of wages to cater for living expenses and whether task performed by proposed employee is an essential part of the employers business. The plaintiff cannot

Researching A Hindu Saint Essay Example | Topics and Well Written Essays - 1500 words

Researching A Hindu Saint - Essay Example Referring to the Bhagavad Gita, he has made use of the Yogas and Vedantas in order to help people understand the importance and implementation of the major themes namely Karma Yoga, Bhakti Yoga and Jnana Yoga. (Vivekananda Kendra) Vivekananda was born in Calcutta on 12th January, 1863 to a Bengali Kayastha family and his birth name was Narendra Nath Datta. He was influenced greatly by both his parents; his father helped him to inculcate within him a sense of logical thinking equipped with rationality whereas his mother assisted him on thinking along the lines of religious spirituality. His guru Ramakrishna also played a major role in his life by teaching him about the faith and service that a man devotes to God and how this service is the same in all religions to all Gods. Swami Vivekananda also was heavily influenced by the teachings in the Bhagavad Gita and remarked on an allegory of the war taking place on the battlefield of Kurukshetra. He stated that the war was a metaphor of th e war that is constantly raging within the mind of a human being with respect to good and evil and what he should give in to. In 1881, Vivekananda experienced a turning point in his life as he met Ramakrishna; it is surprising to note that at first he revolted against all of the ideas of the guru and did not accept him as his senior; he had his own views regarding spirituality and did not believe in Ramakrishna’s vision. However, during the course of studying for five years under him, he began to accept his views and became a man ready to renounce the world in order to understand the realization a man achieves by being close to God. When Ramakrishna began suffering from throat cancer, Vivekananda formed a monastic group of which he was a part of and was given the duty to look after all the other disciples and take forward his teachings. From 1888 to 1893 Vivekananda wandered all over India as a monk with nothing but a pot of water and the robes on his back. He carried with hi m a copy of the Imitation of the Christ and the Bhagavad Gita and during the course of this journey he was able to understand people from different walks of life as he stayed with, and interacted with all kinds of people from all over the country. (Sri Ramakrishna and Swami Vivekananda) After 1893, Vivekananda began travelling abroad with his first visit to Japan. He was very impressed by the cleanliness in the Japanese lifestyle; both in their way of living as well as their attitude. From there on, he visited Chicago where he was taken to the Parliament of World Religions by Prof. John Henry Wright of Harvard University. Vivekananda has hosted several lectures on his tours across England and America and after coming back to India, founded the Ramakrishna Mission all over the country where young learners are taught about the Gita as well as other world religions with emphasis on Hinduism. He has tried to keep Ramakrishna’s message and vision alive by spreading the word about God and self-realization. The essence of his teachings has best been described through a Vedanta philosophy of the soul as potentially divine. He is also considered to be a social reformer as he worked to help the poor and made provisions of providing them with food, shelter as well as knowledge through the Ramakrishna Missions set up throughout the country. The Bhagavad Gita is a 700 verse discourse in Sanskrit, a part of the Sanskrit epic titled the Mahabharata written by Valmiki. Also

Leadership Styles and Conflict Resolution Assignment

Leadership Styles and Conflict Resolution - Assignment Example re not honest when performing their roles as leaders as they tend to misuse the resources and tend to misuse their powers to misuse other people in the group. A leader must be honest in everything they handle, and this creates comfort and confidence with the leadership especially to employees. The second leadership quality is focus. A leader who is focused on his job tends to work better and relate well with his/her employees. For example, if a leader is not sure with what he/she is doing, how can people be sure of him/her and what he is doing? This makes the employees lose respect for the leader and tend to withdraw existing respect they had for the leader. The third leadership quality is respect. Respect is always applicable in all fields. A good leader must pay respect to his/her employees or group members. If a leader respects his/her members, the members of the group will also respect him. It will start by treating people with equal perspectives with no ranks or class (Bass and Ruth 201). The leadership is participative or democratic leadership. This type of leadership calls for participation from group members in helping the leader run errands of the group. This type of leadership is used when the errands of the group are at a standstill. A collective or participative type of decision making is used during this type of leadership. This means that members help the leader to make decisions for the group, and thus, everyone contributes to the decision making (Bass and Ruth 241). At some point in high school, I was captain of the basketball team. It reached a time when there was one student who was a drug addict, but he was the best player in the team. The team patron announced that we should do away with him or else the team would not participate in the competitions that were due in one week. I called for a meeting with the team, and I laid down the topic for discussion. I used participative leadership to arrive at a decision. The team resolved to do away

Historical sites in UAE Research Paper Example | Topics and Well Written Essays - 2250 words

Historical sites in UAE - Research Paper Example The long history of human habitation of the area has brought about a situation where a number of historical sites show evidence of the different eras that have taken place. These have mainly been as a result of the human ability to adapt to their environment and to express themselves through the construction of significant monuments that have ended up becoming significant historical sites. In this paper, there will be a discussion of three important historical sites of the UAE that include Qasr al-Hosn, the Al Badiyah Mosque, and finally, the Al Hili Archeological Park. The Qasr al-Hosn is located in the city of Abu Dhabi and it is considered the oldest stone building in the city. Located in the Sheikh Zayed the First Street, it was constructed in 1761 as a conical tower designed to ensure that the only fresh water well in the area was protected. Seeing the advantage of this site, the ruler of Abu Dhabi, Shakhbut bin Dhiyab Al Nahyan, in 1793 decided to expand this tower into a small fort who also established it into his permanent residence (Maitra 262). As the official seat of the Abu Dhabi sheikhs for centuries, Qasr al-Hosn gained significant value within the emirate because it came to be associated with government. This historical landmark has seen various renovations over its long history, which went according to the taste of the various rulers who occupied it. Following the discovery of oil in the UAE, this site was given a major extension and it took on its current shape as a result of the oil revenues which allowed the Abu Dhabi emirate to have the funds necessary to expand the residence of the emir. As the official seat of the Abu Dhabi government until 1966, this fort has also become the home of the Abu Dhabi Cultural Foundation whose purpose is to preserve the rich cultural history of the emirate. The Qasr al-Hosn has become a major tourist attraction for those who visit the UAE because it

Industrial standard Syringe Essay Example | Topics and Well Written Essays - 750 words

Industrial standard Syringe - Essay Example The present paper deals with a syringe’s low Reynolds number flow. This scenario presents itself in the slow regulated intravenous fusion of drugs and fluids in laboratories or hospitals. For instance, in indicator-dilution experiments, the common values for the Reynolds number are Re= 0.07 (50cc syringe at 1cc/min or Re= 0.015(10cc syringe at 0.1 cc/min). A calibrated infusion pump is often used in maintaining the rates of infusion at constants. In figure 1 the plunger is moving to the left in a cylinder; fluid is pumped through a hollow needle of a diameter that is often less than 3% of the cylinder’s diameter. Because of the geometry the fluid dynamics can be divided into 2 parts: the flow in the needle and the flow in the cylinder. Dagan, Weinbaum and Pfeffer [1] solved the flow in the needle (orifice). They concluded that the velocity profile is mostly Poiseuille, with end effects maintained at a length of just  ¼ the diameter of the needle. In the sections that follow we will examine the cylinder region, with the needle hole estimated by a sink. x’s partial differentiation is numerically solved using finite difference techniques, which result in an estimation for x at every grid point. In the middle way from all borders, standard difference equations are applied in the estimation of the partial derivatives. Close to the borders, multiple standard equations are required. These new difference equations, using both partials and values of x on the borders, were derived via the symbolic manipulation package, SMP. All the finite difference estimations applied are provided in Appendix A. The finite difference estimation produces results in a linear system of equations Ax = b, with dimension being 2500 for a basic 50 x 50 grid. Due to the fact that the boundary conditions are asymmetric and difference equations using known derivatives are used, the coefficient matrix A is

International Politics Essay Example for Free

International Politics Essay Transformation—is one of the few words which could be used in order to define and describe the current situation of the international community. In every parts of the world, transformation is currently occurring from the simple acquisition of one product to another. Such situation could be one of the few examples of the changes which are present in the current society. In the modern society, boundaries and limits had now been erased due to the technology including the issues facing most states in the global community. The past limitation of states in surpassing territorial boundaries of their own state is now removed. Such hindrances are not a concern any longer. The gaps in which divides states are now being linked therefore making each and everyone of us connected. The far away lands of Africa or Europe could now be reached through one click of a button. The then complicated processes of communication as well as the process of international relations had changed due to globalization. The process of globalization became a significant change in the relations of states. In addition, states are not only the actors in the international community. The active participation of non-state actors had been highlighted in the past events which had recently occurred such as wars, conflicts and environmental phenomenon. In the past such as the events of the World War I, nations were the only actors in the war. Decisions were only influenced by the leaders of the states involved. Although international organizations were present in providing aid to the victims of the war, they were not equally involved in the decision making process. But as these events unfold, it is evident that international organizations are similarly participating with the political issues at hand. In the principle of realism, the main actors were only states however; in the view of the liberalism theory, other actors such that of international organizations, trans-national organizations, multinational corporations and the likes. In the book of Baylis and Smith, the authors stated that in â€Å"Realists emphasize states’ ruthlessly self-interested search for territorial, military and economic resources† (Baylis and Smith, 2008). On the other hand, Liberalism or Idealism pursues to promote internationalism during the inter-war period (Baylis and Smith, 2008). The theory of liberalism’s main idea is to attach government together with good governance which will create a connection between states and the societies of the global community. Liberalism promotes the need for the world to unite and commune with the issues of the international community equally. However, unlike the liberalism, realists approach the view of internationalism is translated as anarchy. (Baylis and Smith, 2008) Evidently, the world is already shifting and adopting another form of ideology other than realism which was mainly utilized in the past. In the inter-war years, the liberalist theorists started to promote their perspective in which advocates that international institutions should encourage the values of having order, justice, liberty and toleration within the relationship of states. It was believed in such theory that the conflicts between states could not only be resolved through the use of force and warfare. International institutions or organizations much act as mediators when conflicts are at hand. In addition, such international institutions must be the area of discussion for the reason that it could create other actions in resolving disputes in a much objective manner. Therefore, the liberalists were able to influence every state in creating an international organization which lead to the creation of the League of Nations in which became the fundamental foundation of the United Nations. Although the ideas of the liberalists were idealistic, each state must be a member of the organization in order to fully accomplish and pursue the goals of the international organization. (Baylis and Smith, 2008) In our changing world, the past conflicts and issues of a state are realized to also be affecting the world. The recent war on terror had been actively participated by different states in order to deter the effects of terrorism. After the war on terror, many states changes their view point which such situations—following the chief state which proclaimed the war. The war on terror became a global issue due to the involvement of different states. Additionally, international organizations became a great factor in such war. The war in Afghanistan for example, the United Nations became one of the main decision maker and supporter of the war. The United Nations launched protocols and written agendas in order to promote action against the cruel ruling and the storage of the weapons of mass destruction of Saddam Hussein. In the incident given, the United Nations played a great role in encouraging and promoting in the issue against terrorism. United Nations became one of the main actors is countering against terrorism unlike in the past. (Bredel, 2003) Another issue which is currently in debate until this day is the issues concerning the global environment—climate change. This issue is one of the most controversial and debated issues because it is one of the problems of the world which passes the boundaries of states. Climate change not only affects the climate and the environment but also the politics and economics of each state. One of the few very specific problems under climate change is pollution. Pollution had been a great problem for different states for the reason that it encompasses the boundaries of states. It is known that most industries or factory excretes smoke which turns out to be air pollutants due to the machineries used to create products and the likes. Water pollution also has the same situation for the reason that it flows although out different forms of water and continuously flow to the water of other states. The problem obviously passes through the limitation of the international law and protocols available. The problem becomes a trans-national issue that requires states to cooperate and coordinate with each other in order to solve such crisis. With the issue of climate change, trans-national entities are the most reliable organizations in laying down such issues. Trans-national organizations provide states a much immediate and larger picture of the issue. Due to the personality of trans-national organization, different organizations that aim for the same goals as others come together to be able to solve the dilemmas at hand. With the issue of climate change, the main agent which is very much focused is the United Nations. The international organization created a branch which focuses on the issues of environment which is the United Nations Environment Programme (UNEP). The branch of United Nations provides answer to the needs of each state in order to address the problem. The UNEP together with the states and other organizations with the same advocacy such as Green Peace and other local organizations with in the various states to be able to provide answer to the issue. The role of non-state actors and trans-national networks had become significant in the international community due to the promotion of international organization during crisis. The power given to non-state actors as well as trans-national networks enable these agencies to freely interfere with the conflicts of states and within states. Therefore, these groups provide their own view points, influencing states and individuals with their perspective. Most of the time, such organizations changes the civil society which then results to the change of the government. One example that could be cited is the pursuance of NGOs (Non-Governmental Organizations) in Asia to promote change in the civil society, therefore promoting development within the society. It is stated by Harriet Bulkeley and Michele Merrill Betsill (2005) in their book that â€Å"the international, regional, national and local interact â€Å"with actors influencing the activities of different levels simultaneously† (cited in O’ Riordan and Jordan 1996). With the statement given by the authors, it is evident that the role of non-state actors as well as trans-national organization is equally important as the responsibility of states. Therefore, the international order is changed due to the additional actors that are also acting in the international community. Currently, the international community is evidently reliant to non-state actors as well as to the trans-national networks due to the important role that it is undertaking with conflicts and decision making processes of a state. Non-state actors and trans-national networks had become one of the main components of international relations whether it may be in conflict resolution or in times of celebration. Such groups empower and support positive ideology due to the idealistic nature of most non-state and trans-national networks. The usual â€Å"state-only† theory had now been changed into a new form of relations of states which brings together actors that has the same goals to attain making the relations of states peaceful. Although most non-state actors and trans-national networks aims to create a united international community, there are also groups alike that promotes otherwise. One well known group is the Al-Qaeda which seeks to promote terror and violence from the eyes of most states. Although Al-Qaeda is seen as an extremist group in promoting change, it is also considered a trans-national network for the reason that it encompasses the boundaries of its home state and promotes their ideology to the world. The group creates networks in different parts of the world while maintaining a balance relation with other networks associated to the group. Due to the negative effects they such trans-national network is creating; it definitely changes the order of the international community. Not only it brings terror to the whole global community but the group promotes division and conflict within the global society. (Pearlstein, 2004) In conclusion, the issues that the international community is facing are now crossing the boundaries of states such that of the terrorism and climate change. There is a need for states to get together and resolve such dilemma. Therefore, trans-national networks and non-state actors play a vital role in resolving such problems. The non-state and trans-national networks are the best area for the resolution of such conflicts because objectiveness within the situation is achieved. The international community sets the non-states actors and trans-national networks as the one of the numerous vital actors in the global community. The participation of such actors promotes the unity of the whole international community in times of crisis or triumph. References Baylis J. , Smith S. , Owens, P. Eds.(2008).

Static Voltage Stability Analysis In Power Systems Engineering Essay

Static Voltage Stability Analysis In Power Systems Engineering Essay Voltage stability, one of the principal aspects of power system stability, has been the main reason for many of major power system blackout incidents over the last few decades. It is acknowledged universally that voltage stability is and will remain a challenge in the 21st century, even likely to increase in importance. Therefore a better understanding of voltage stability in power systems is necessary for power engineers, who might participate in the planning, designing, and operation of modern power systems. This report talks about a relevant engineering thesis project: Static Voltage Stability Analysis in Power Systems, which is carried out for 2 semesters from July 2009 to June 2010. The aim of this thesis project is to conduct a more comprehensive study into the theory of static voltage stability, and investigate a new approach for power flow analysis: 3-dimension P-Q-V curve. First of all, the basic knowledge of static voltage stability is reviewed, and analysis on an elementary power system, radial system, is carried out including power flow study, P-V and Q-V curve analysis. Based on the 2- dimension P-V and Q-V plotting, the relationship of P, Q, and V is studied and a new method for static voltage stability analysis is tried: P-Q-V curve. The second part of this project focuses on the analysis of WSCC three-generator-nine-bus system. Simulation of the system is carried through by means of UWPFLOW and POWERWORLD.

Since the first electric network in the United States was established at the Pearl Street Station in New York City by Thomas Edison in 1882 [1], power systems have been experiencing more than 100 years development and improvement. Nowadays, modern power system has developed to be a complex interconnected network, which can be subdivided into four parts: Generation Private and publicly owned generators produce the electricity that feeds into high voltage grids. Transmission High voltage transmission grids transport power from generating units at various locations to distribution systems which ultimately supply the load. Distribution Distribution systems deliver the power from local bulk supply points to the consumers service-entrance equipments. Loads Loads of power systems are composed of industrial, commercial, and residential load. Figure 1.1 Modern Power System [2] Power System Stability A power system is said to be stable if it has the property that it retains a state of equilibrium under normal operating conditions and regains an acceptable state of equilibrium after being subjected to a disturbance. Of all the complex phenomena on power system, power system stability is the most intricate to understand and challenging to analyze [3]. Damage to power system stability may cause the system to blackout or collapse as well as other catastrophic incidents, leading to enormous social and economic losses. Classification of Power System Stability Based on the systems different properties, network structures and operation modes, the system instability can behave in many different ways. Accordingly power system stability study is divided mainly into three fields: angle stability, frequency stability and voltage stability. The diagram below shows visually the classification of power system stability. Figure 1.2 Classification of Power System Stability History of Study on Power System Stability Initially, angular stability was firstly paid attention to and studied since power transmission capability had traditionally been limited by either rotor angle (synchronous) stability or by thermal loading capability. And the blackout problems had been associated with transient stability, which were diminished by fast short circuit clearing, powerful excitation systems and varies special stability controls [3]. In other words, nowadays the theory and methods on angular stability are relatively more complete. Meanwhile, study on voltage stability had been quite slow, which mainly attributed to two reasons: Incidents caused by voltage instability or voltage collapse occurred relatively late, not until which did people paid attention to voltage instability problems. Understanding of voltage instability was not so profound as other kinds of instability problems in the early days. Varies of issues arose during the study on voltage stability such as load-based modeling, dynamic behaviors of different components as well as their interaction, and so on. Overview of Power System Voltage Stability Voltage Instability Incidents in the World Power system voltage stability was firstly introduced in 1940s, but failed to draw peoples attention until 1970s, since which voltage instability and collapse had resulted in several major system failures or blackouts throughout the world, as listed below [4, 5, 22]: August 22, 1970, Japan, 30 minutes; September 22, 1970, New York, several hours; September 22, 1977, Jacksonville, Florida, few minutes; December 19, 1978, France, 26 minutes; August 4, 1982, Northern Belgium, 4.5 minutes; September 2, November 26, December 28 30, 1982, Florida, 1-3 minutes; May 21, 1983, Northern California, 2 minutes; December 27, 1983, Sweden, 55 seconds; June 11, 1984, Northeastern USA, several hours; May 17, 1985, South Florida, 4 seconds; April 1986, Winnipeg, Canada Nelson River HVDC links, 1 second; May 20, 1986, England, 5 minutes; November 1986, SE Brazil, Paraguay, 2 seconds; January 12, 1987, Western France, 6-7 minutes; July 20, 1987, Illinoisand India, several hours; July 23, 1987, Tokyo Japan, 20 minutes; August 22, 1987, Western Tennessee, 10 seconds; July 2, 1996, Western System Coordination Council (WSCC), Northern USA; August 1996, Malaysia; August 14, 2003, USA Canada; September 28, 2003, Italy. Progress of Study on Voltage Stability The large numbers of worldwide voltage collapse incidents made it become the focus of worlds attention to study voltage stability of power system. In the 1982s researching list of Electric Power Research Institute (EPRI) in USA, voltage stability was considered as the most significant issue. Over the last thirty years, and especially over about the last twenty years, utility engineers, consultants, and university researchers have intensely studied voltage stability. Hundreds of technical papers have resulted, along with conferences, symposiums, and seminars. Utilities have developed practical analysis techniques, and are now planning and operating power systems to prevent voltage instability for credible disturbances [6]. Importance of Voltage Stability in Future In a foreseeable future, the global fast-growing power consumption will require more intensive use of available transmission facilities, which means an operation of power systems closer to their voltage stability limits. The increased use of existing transmission is made possible, in part, by reactive power compensation [6]. Undoubtedly, voltage stability is and will remain a challenge in the 21st century, even likely to increase in importance. Therefore a better understanding of voltage stability in power systems is necessary for power engineers, who might participate in the planning, designing, and operation of modern power systems. Topic Definition and Scope The topic of this project is Static Voltage Stability Analysis in Power Systems, which mainly focuses on the following: Overview of the phenomena of static voltage stability; Analysis associated with the phenomena; Reasons why voltage collapse happens; Measures to improve static voltage stability. In consideration of restrictions on the simulation, a three-generator-nine-bus case is used throughout the whole project while a typical two-bus (one-generator-one-load) case is used for the P-Q-V curve analysis. Aims and Objectives The main objective of this project is to get a wider and deeper understanding of static voltage stability in power systems, which can be reduced into sub-objectives: To conduct a more comprehensive study into the theory of static voltage stability; To look for reasons why voltage collapse happens; To investigate a new approach for power flow analysis: 3-dimension P-Q-V plotting; To propose proper measures of improving static voltage stability in power systems; To conclude generation direction and load direction for the analyzed power system. CHAPTER 2 POWER SYSTEM VOLTAGE STABILITY Basic Concepts of Voltage Stability IEEE Definitions IEEE [7] provided a formal definition of voltage stability and relative concepts as given below: Voltage Stability: Voltage stability is the ability of a system to maintain voltage so that when load admittance is increased, load power will increase and so that both power and voltage are controllable. Voltage Collapse: Voltage collapse is the process by which voltage instability leads to very low voltage profile in a significant part of the system. Voltage Security: Voltage security is the ability of a system not only to operate stably, but also to remain stable (as for as the maintenance of system voltage is concerned) following any reasonable credible contingency or adverse system change. CIGRE Definitions Nevertheless, the above definitions of voltage stability conditions were not directly compatible with the general IEEE definition for stability concept. Hence new definitions were given in CIGRE report [8], which are as following: Voltage Stability: A power system, at a given operating state and subjected to a given disturbance, is voltage stable if voltages near loads approach post-disturbance equilibrium values. The disturbed state is within the region of the stable post-disturbance equilibrium. Voltage Instability: Voltage instability is the absence of voltage stability, and results in progressive voltage decrease (or increase). Destabilizing control reaching limits, or other control actions (e.g. load connection), however, may establish global stability. Voltage Collapse: Following voltage instability, a power system undergoes voltage collapse if the post-disturbance equilibrium voltages near loads are below acceptable limits. Voltage collapse in the system may be either total (blackout) or partial. Voltage collapse is more complex than simple voltage instability leading to a low-voltage profile in a significant part of the power system. Other Relative Concepts Large-disturbance Voltage Stability: Large-disturbance voltage stability is concerned with a systems ability to control voltages following large disturbances such as system faults, loss of generation, or circuit contingencies. The study period of interest may extend from a few seconds to tens of minutes. Therefore, long-term dynamic simulations are required for analysis. Small-disturbance Voltage Stability: Small-disturbance voltage stability is concerned with a systems ability to control voltages following small perturbations such as incremental changes in system load. For such case, static analysis is effectively used. Relation of Voltage Stability to Rotor Angle Stability Voltage stability and rotor angle (or synchronous) stability are more or less interlinked. Transient voltage stability is often interlinked with transient rotor angle stability, and slower forms of voltage stability are interconnected with small-disturbance rotor angle stability. Voltage Stability is concerned with load areas and load characteristics. For rotor stability, we are often concerned with integrating remote power plants to a large system over long transmission lines. Voltage stability is basically load stability, and rotor angle stability is basically generator stability [6]. In a large interconnected system, voltage collapse of a load is possible without loss of synchronism of any generators. Transient voltage stability is usually closely associated with transient rotor angle stability. Long-term voltage stability is less interlinked with rotor angle stability. We can consider that if voltage collapses at a point in a transmission system remote from loads, it is an angle instability problem. If voltage collapses in a load area, it is possibly mainly a voltage instability problem. CHAPTER 3 STATIC VOLTAGE STABILITY ANALYSIS OF ELEMENTARY POWER SYSTEM Introduction of an Elementary Model: Radial System Simple radial system network is used to develop most of the concepts of the static voltage stability. Once basic concepts are understood, we can represent as much as appropriate in computer simulation, which will be carried out in Chapter 4. Figure 3.1 shows an equivalent circuit of the power system, and a model called radial system is formed to represent such power system, as shown in Figure 3.2. Figure 3.1 Equivalent Circuit of Power System Figure 3.2 Radial System Model The sending-end and receiving-end voltages are assumed to be fixed and can be interpreted as points in large systems where voltages are stiff or secure. The sending end and receiving end are connected by an equivalent reactance. Basic Analysis of Radial System Active Power Transmission Applying the radial system in Figure 3.2, the relations can be easily calculated: Similarly, for the sending end: The familiar equations for and are equal since we assume a lossless system, and maximum power transferred is at a power load angle equal to 90 degree. Note that the 90-degree maximum power angle is nominal, in other words, maximum power occurs at a different angle if we apply transmission losses or resistive shunt loads. And the case with impedance load at the receiving end will be discussed in section 3.2.2. Reactive Power Transmission In the study of the static voltage stability in power system, the transmission of reactive power is especially of interest. Usually we are interested in variable voltage magnitudes. Particularly, we are interested in the reactive power that can be transmitted across a transmission line, or a transformer as the receiving-end voltage sags during a voltage emergency or collapse. Considering the reactive power flow over the transmission line alone, we can write approximate formulas for Equations (3.3) and (3.5) in terms of small angles by using : From Equations (3.6) and (3.7), it can be observed that reactive power transmission depends mainly on voltage magnitudes and flows from the higher voltage to the lower voltage. Such observation, however, cannot be applied in the case of high stress, i.e. high power transfers and angles, where the angle is large enough and no longer approaches 1. This is important as voltage stability problems normally happen during highly stressed conditions. Difficulties with Reactive Power Transmission Reactive Power Transmission Behavior in Different Cases First of all, take an example of the radial system in Figure 3.2, assuming X=0.2 p.u. with varied values of voltage magnitude and angles, i.e. varied loading conditions. Applying Equations (3.3) and (3.5), and can be calculated as listed in the following table: Conditions (p.u.) (p.u.) (degree) (p.u.) (p.u.) Lightly loaded 1.10 1.00 10 0.634 0.416 Moderately loaded 1.05 0.90 20 1.072 0.390 Heavily loaded 1.00 0.80 50 2.429 -0.629 Table 3.1 Reactive Power Transmission in varied conditions From the table, it is clear that at higher loading, transmission lines are more difficult to transfer reactive power and reactive power cannot be transmitted across large power angles (the value of becomes negative in the case with a power angle of 50 degree). Minimizing Transfer of Reactive Power High angles are due to long lines and high real power transfers. It is therefore required to maintain voltage magnitude profiles with voltages of approximately 1 p.u.. Compared with real power transfers, reactive power cannot be transmitted across long distances. It has been observed that the greater distance of the reactive power sources from the reactive demand will lead to: [9] greater voltage gradient on the lines supplying the reactive power greater amount of required reactive power compensation more difficult to control the voltage level Another reason to minimize the transfer of reactive power is minimizing the real and reactive losses. The purpose to reduce real losses is due to economic reasons while minimizing the reactive losses can reduce investment in reactive devices such as shunt capacitors. As we know, the losses across the series impedance of a transmission line are and . For , we have: and Obviously, to minimize losses, we should minimize reactive power transfer and keep voltage high at the same time. Keeping voltage high to minimize reactive losses helps maintain voltage stability. In other words, reactive power should be generated close to the receiving end. Power Flow Analysis In a power system, powers are known rather than currents. Thus power flow analysis is backbone of static voltage stability studies. Power flow analysis, also known as load flow analysis, involves the calculation of power flows and voltages of a transmission network for specified terminals or bus conditions. Bus Classification In solving a power flow problem, a power system is supposed to be operating under balanced conditions and a single-phase model is used. Associated with each bus are four quantities: active power P, reactive power Q, voltage magnitude , and voltage angle. The following types of buses (nodes) are represented, and at each bus two of the above four quantities are specified: Voltage-controlled (P-V) buses: These buses are the generator buses. They are also known as regulated buses or P-V buses. For such kind of buses, the real power P and voltage magnitude are specified, while the reactive power Q and the voltage angle are unknown. Load (P-Q) buses: Load buses are also called P-Q buses as their real power P and reactive power Q are specified. The voltage magnitude and angle are to be determined. Slack (Swing) bus: Such bus is taken as reference of the whole power system. For a slack bus, the voltage magnitude and voltage angle are specified. As the power losses in the system are not known a priori, at least one bus must have unspecified P and Q. Thus the slack bus is the only bus with known voltage. This bus makes up the difference between the scheduled loads and generated power that are caused by the losses in the network [1]. Traditionally while analyzing, the voltage magnitude of slack bus is assumed to be 1 p.u. and the voltage angle is assumed to be 0 degree. Transmission Line Modeling The transmission line is traditionally represented with two types of models: nominal model and nominal T model, as shown in Figure 3.3 and Figure 3.4 where Z is the series impedance and Y is the shunt admittance due to the line charging capacitance. Neither nominal T or nominal à Ã¢â€š ¬ exactly represent the actual line, however, they brings great convenience in the power flow analysis, especially in the application of NEWTON-RAPHSON method, which will be discussed in the coming section. Figure 3.3 Nominal Model Figure 3.4 Nominal T Model NEWTON-RAPHSON Power Flow Method In order to include all the three types of buses (P-V bus, P-Q bus and slack bus as introduced in 3.3.1) at the same case, a 3-bus power system is considered as shown in Figure 3.5, where Bus 1 is the slack bus, i.e. and are specified as . Bus 2 is a voltage-controlled bus, i.e. and are known while and are unknown. Bus 3 is a load bus, i.e. and are known while and are unknown. Figure 3.5 3-bus Power System The network performance equation of such a sample is: where Applying the bus-loading equations: Now NEWTON-RAPHSON Power Flow Method can be approached as: P-V Curve Analysis P-V curve is useful for conceptual analysis of static voltage stability and for study of radial system, where P is the load in an area and V is the voltage at a critical or representative bus. Besides, P can also be the power transferred across a transmission interface or interconnection. Voltage at several busses can be plotted. Consider the radial system as shown in Figure 3.2. The receiving-end active power can be expressed as in the Equation 3.2. Then a P-V cueve can be plotted as in Figure 3.6, which shows relationship between P and V at the receving end for different values of load power factor and the locus of the critical operting point is shown by the dotted line. Nornally, only the operting points above the locus of the critical points represent satisfying operating condition. A sudden reduction in power factor or increase in Q can thus cause the system to change from a stable operating condition to an unsatisfactory and possibly unstable [10]. Figure 3.6 V versus P for different power factors [10] Q-V Curve Analysis Q-V curve is presently the workhorse method of voltage stability analysis at many utilities [6]. Considering the system in Figure 3.2, we can obtain reactive power both at sending end and receiving end, or and by means of Equation (3.5) and Equation (3.3). Then a Q-V cueve can be plotted as in Figure 3.7, which shows relationship between Q and V. The reactive power margin is the MVAr distance from the operating point to either the bottom of the curve, or to a point thaere the voltage squared characteristic if an applied capacitor is tanfent to the V-Q curve [6]. Additionally, the slope of the V-Q curve indicates the stiffness of the bus. Figure 3.7 Typical Q V Curve A New Method for Static Voltage Stability Analysis: P-Q-V Curve Analysis Introduction of MATLAB Software MATLAB is a numerical computing environment and fourth generation programming language. Developed by The MathWorks, MATLAB allows matrix manipulation, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs in other languages [18]. An additional package, Simulink, adds graphical multi-domain simulation. This project greatly benefits from MATLAB to handle 3-dimension curve drawing for P-Q-V curve study, as well as the matrix manipulation associated with power flow analysis, 2-dimension curve plotting for P-V/Q-V curve study in the analysis of WSCC nine-bus system, which will be described in details in CHAPTER 4. P-Q-V Curve In this section, for convenience of forming an ideal voltage source, we assume the angle of the to be zero while the angle of to be degree. Then Equation 3.2 and 3.3 become: Noting that We can eliminate in Equations 3.16 and 3.17, which obtains or Obviously, with specified , and , Equation 3.19 shows relationship of , and . To work out such relationship visually, MATLAB is applied and a P-Q-V curve is obtained as below, where P stands for , Q stands for V stands for and E stands for . Refer to Appendix A for details on MATLAB codes, with the assumsion that E = 1 , X= 0.2 and the values of tan are chosen randomly as [-0.41, -0.2, 0, 0.2, 0.41, 1, 10, 100, 1000]. Figure 3.8 P Q V Curve CHAPTER 4 STATIC VOLTAGE STABILITY ANALYSIS OF WSCC NINE-BUS SYSTEM Introduction of WSCC Nine-bus System WSCC nine-bus system is a typical testing system develped by Western Systems Coordinating Council. It is commonly uesd in jornals and papers for power system studying. Figure 4.1 shows an overview of the WSCC nine-bus system. Refer to Appendix H for parameters of this system. Figure 4.1 Single Line Diagram of WSCC Nine-bus System Introduction of UWPFLOW Software For determining the static voltage stability of the WSCC nine-bus system, UWPFLOW software is used. This software has been developed by University of Waterloo, Canada, and distributed free on the Power Globe. It was written in C and runs under DOS and UNIX enviroments. It has no limitation on the system size other than those imposed by memory limitation in the corresponding enviroment, i.e. RAM and swap space in the UNIX and exrended memory in DOS [16, 20]. UWPFLOW is a research tool that has been designed to calculate local bifurcation characterized by a singularity in the power system Jacobian. This was developed based on power flow method. This software also generates a series of output files that allow further analysis. UWPFLOW reads AC power flow data in WSCC format [11] or IEEE common format [12], DC data in ETMSP format [13], FACTS devices data in s special format described in [14], and steady state load model data in OH format [15]. However in the present study IEEE common format data is used. Additional UN format data is required for bifurcation analysis, such as direction of generation change, direction of load change and maximum genertion limit [10]. The software assumes that one parameter the loading factor, is allowed to change. All steady state system controls remain operational unless otherwise specified by means of the software option. Introduction of POWERWORLD Software POWERWORLD Simulator is an interactive power system simulation package designed to simulate high voltage power system operation on a time frame ranging from several minutes to several days [17]. POWERWORLD provides a linear programming based optimal power flow package Simulator OPF, which ideally suits to do power flow analysis. Whats more, the planning-mode tool Simulator PVQV fulfills the need of Q-V curve drawing. Throughout the project, PowerWorld Simulator will be used to carry out power flow analysis and Q-V curve study of the twelve-bus case. Analysis of WSCC Nine-bus System Direct Method: Repeated Power Flow First of all, the WSCC nine-bus system in Figure 4.1 is built in UWPFLOW software. By running the system and increasing the loading level of step by step, attention will be focused on getting convergence and the maximum loading level. For loading direction, assume all the loads are increased by the same ratio, and only generator at Bus-1 is allowed to dispatch required additional real power. With the load P and Q increased simultaneously with the ratio of 10%, in the same loading direction, the bus voltages in per unit measurement are tabulated in Table 4.1. Couples of data points are collected near the system divergence point. Table 4.1 has shown that the system started to collapse (or diverge) at the point where all loads at the 3 load buses are increased in the same direction till 116%. Note that in Table 4.1, the starting point is denoted as 0% as there is no additional loads added, which is named as basic load.

Buddhism Essay -- essays research papers fc

Buddhism Buddhism is one of the biggest religions founded in India in the 6th and 5th cent. BC by Siddhartha Gautama, called the Buddha. One of the great Asian religions teaches the practice of the observance of moral precepts. The basic doctrines include the four noble truths taught by the Buddha. Since it was first introduced into China from India, Buddhism has had a history that has been characterized by periods of sometimes awkward and irregular development. This has mainly been the result of the clash of two cultures, each with a long history of tradition. Most of the difficulties have arisen due to the transplanting of an Indian religious/philosophical system onto a culture strongly dominated by indigenous secular, philosophical and religious systems. In spite of these difficulties, Chinese Buddhism has come to have an important influence on the growth and development of Buddhism in general and this has occurred largely because of its own innovatory contributions.(Eliade, M. p.16-29) Th e spread of Buddhism into China began in Central Asia and was facilitated by the efforts of the Indo-Scythian king Kanishka (Encyclopedia Britt. 273-274) of the Kushan dynasty which ruled in northern India, Afghanistan and parts of Central Asia in the 1st and 2nd centuries (Encyclopedia Britt. 274). He is said to have undergone an Ashoka-like conversion upon seeing the slaughter caused by his campaigns. Around the beginning of the common era, Buddhism started to filter into China from Central Asia via the Silk Road, brought by monks, merchants and other travelers. It also entered later via trade routes around and through Southeast Asia. It was nurtured in the expatriate community of Loyang and other northern cities. (The Encyclopedia of Religion p58-62) Siddhartha (Buddha) was born around 563 B.C.E. in the town of Kapilavastu (located in today's Nepal).

Holocaust in Germany, Japan, and China :: essays papers

Holocaust in Germany, Japan, and China Eleven million precious lives were lost during the Holocaust of World War II. Six million of these were Polish citizens. Half of these Polish citizens were non-Jews. On August 22, 1939, a few days before the official start of World War II, Hitler authorized his commanders, with these infamous words, to kill "without pity or mercy, all men, women, and children of Polish descent or language. Only in this way can we obtain the living space [lebensraum] we need". Heinrich Himmler echoed Hitler's decree: "All Poles will disappear from the world.... It is essential that the great German people should consider it as its major task to destroy all Poles." When someone mentions the word holocaust, most often people will relate that word with the Germans and Jews during World War II. When Japan is mentioned, the first things that come to mind are the atomic bombs dropped on Hiroshima and Nagasaki. The Nanjing Massacre is known as the forgotten holocaust and very oddly, it truly has been forgotten. In this forgotten holocaust, three hundred thousand people were brutally murdered and 20,000 women were raped in the city of Nanjing, during the years of 1937-1938 (Yao). The Chinese Nationalist Government moved the capital of China from Peking to Nanjing in 1928. Nanking's population in the mid 1930s was well over one million, mainly because many refugees were fleeing from the Japanese army that had invaded China in 1931. Japan had entered China and other parts of Asia before World War II began, and didn't stop until the U. S. dropped the atomic bombs on Japanese soil in early 1945. It is said that the Japanese military machine was motivated by the aggression and uncontrollable desire for expansion and imperialism. On December 9, 1937, Chinese troops endered in the city of Nanjing, followed by a massive Japanese attack on the city (Yao). For the next six weeks, this capital was filled with brutal, unhuman, and terribly violent acts now known as the Nanjing Massacre. The Japanese committed venomous acts against innocent civilians, Chinese soldiers, refugees, and many others. The crimes ranged from mass execution to burning, raping, and looting. On December 13, many of the refugees tried to flee for their lives by crossing the Yangtze River. When they arrived at the river there was no type of transportation for them to cross.

Alice Walker: Peeling an Essence Essay

As an African-American novelist, short–story writer, essayist, poet, critic, and editor, Alice Walker’s plethora of literary works examines many aspects of African American life as well as historical issues that are further developed by Walker’s unique point of view. Writers like Alice Walker make it possible to bring words and emotions to voices and events that are often silenced. Far from the traditional image of the artist, she has sought what amounts to a personal relationship with her readers. She has also taken positions of passionate advocacy, most notably in her campaign against ritual genital mutilation of young women, a practice still institutionalized in many parts of the world, as well as the fight for equal rights for African Americans. Her writing has been praised around the world, increasing its profound impact on literature, social and political areas of American life. Moreover, Walker’s turbulent childhood in addition to growing up during an era where African-Americans like herself were fighting for freedom, increased her dedication to become both a reflective and revolutionary author. Alice Malsenior Walker was born on February 9, 1944, in Eatonton, Georgia, to Willie Lee and Minnie Tallulah Grant-Walker. Like many of Walker’s fictional characters, she was the daughter of a sharecropper and the youngest of eight children (Bates, Alice Walker: A Critical Companion). Alice’s father had always taken education very seriously in an era where the schooling of black children, especially black females, was very rare. Nevertheless, Willie enrolled his young daughter in school at the age of four where she was then able to skip two grades up to first grade due to her intellectual potential (Bates, Alice Walker: A Critical Companion). Though it may seem like Alice’s father was unorthodox, Willie was â€Å"blind to his own sexism. † He believed that the traditional role of women was to take care of the house as well as the children. Due to his opinion on the limits of being a women, Alice’s relationship with her father declined over time and was even reflected upon in some of her novels (Bates, Alice Walker: A Critical Companion). Although Walker did indeed challenge the wisdom of her father, she clung tight to her mother for comfort and formed an unbreakable bond. Minnie Walker was Alice’s greatest support system. She approved of Alice’s ebellious ways as a young girl in addition to teaching her life lessons that would be underlying tones in her multiple works (Bates, Alice Walker: A Critical Companion). Walker was a confident young girl until 1952, when an accident involving a BB gun left her blinded her in one eye. Although her older brother offered to pay for an operation to correct the impairment, Walker would never fully recover the sight of her right eye. The young Alice Walker would begin wearing glasses for the remainder of her life. The ridicule and loneliness that was created from her blindness led Walker into writing her first poetry pieces. She found that writing demanded peace and quiet, but these were difficult things to come by when ten people lived in four rooms (Bates, Alice Walker: A Critical Companion). It was then that Walker became secluded and reserved and dreamed of suicide, but at the same time found solace in writing and became an observer rather than a participator in everyday life. Walker attended segregated schools which would be described as inferior by current standards, yet she recalled that she had terrific teachers who encouraged her to believe the world she was reaching for actually existed (Bates, Alice Walker: A Critical Companion). Although Walker grew up in a poor environment, she was supported by her community and by the knowledge that she could choose her own identity. Moreover, Walker insisted that her mother granted her â€Å"permission† to be a writer and gave her the social, spiritual, and moral substance for her stories. Later before attending college, Alice would ask her mother permission to become a professional writer (Bates, Alice Walker: A Critical Companion). Alice concentrated and studied hard in school. She graduated as valedictorian from her high school and went on to attend the local Spelman College in Atlanta, Georgia. She was greatly influenced by one of her professors there named Howard Zin, who she worked closely with on civil rights rallies. She became a volunteer for registered voters of Georgia and began attending political rallies for civil rights. Zin would eventually become an influence for some of Alice Walker’s later writing. In 1963, Walker left Spelman for Sarah Lawrence College, a place housing only a handful of African American people, most of them men. This was Walker’s predecessor to participating in many civil rights demonstrations and meeting Martin Luther King at his home in recognition of her invitation to the Youth World Peace Festival in Finland (Bates, Alice Walker: A Critical Companion). 1964 was the turning point for Alice Walker. Realising that she was pregnant she contemplated suicide and slept with her razor under her pillow for three nights (Bates, Alice Walker: A Critical Companion). During the same week, Walker again turned to writing as a natural outlet for her distress. She stopped writing only to eat and sleep. Thankfully, through the help of a friend, Walker was able to attain a safe abortion. The end product of weeks of anguish was, among other things, a story entitled â€Å"To Hell with Dying† and with the help of teacher Muriel Ruykeyser this was published in 1965 (Bates, Alice Walker: A Critical Companion). In the same year, she graduated from Lawrence College. After moving to New York City in November of the same year Walker worked for the welfare system. She soon moved back however and in 1966 fell in love with civil rights lawyer Melvyn Laventhal. They met while working at the Head Start Program in Mississippi. The marriage was extremely controversial as Mel Leventhal was Jewish and Caucasian and Walker was African American (Bates, Alice Walker: A Critical Companion). The union between the couple was the first legal marriage in the state of Mississippi that was inter-racial. In 1968, one year into the marriage, Alice published her poetry collection, â€Å"Once. † This was followed by Mel and Alice’s birth of their first daughter, Rebecca, but the marriage eventually fell apart under the turmoil and strife of the time period (Bates, Alice Walker: A Critical Companion). Alice Walker’s writings continued to create discussions and controversy in both the literary and political arenas. Between 1968 and 1971, Alice would be a teacher in the Black Studies programs at two different colleges. She spent a year at Jackson State College and another year teaching at Tougaloo College. Alice Walker’s writing career would surge in the 1970’s with the publishing of her first novel, The Third Life of Grange Copeland (Smith, Jessie). The predominant issues and themes of her writings were civil rights based. Many of her stories and poems focus on rape, sexism, racism, violence, segregation and relationship problems. It would later be openly announced that Alice Walker had a bi-sexual orientation (Bates, Alice Walker: A Critical Companion). In 1973, Alice Walker joined Ms. Magazine to publish short stories and poetry. She would also publish many different articles focusing on the theme of civil rights, animal rights and environmental issues. In 1973, Walker would publish the short story collection, â€Å"In Love and Trouble: Stories of Black Women†, and the poem collection, â€Å"Revolutionary Petunias and Other Poems†. Her second novel talked about the life of being an activist in the civil rights and political movements in the South. It is believed that much of Meridian parallels or reflects on Walker’s own life. Meridian was published in 1976 and earned Walker much recognition (Smith, Jessie). The focus of the book was accepting one’s mistakes and taking full responsibility for our actions. There were no excuses made and people greatly admired and respected Walker for this writing piece (Bates, Alice Walker: A Critical Companion). Her political venues later turned from the problems of segregation and racism in the South to issues abroad. During her junior year in college, Alice Walker did her internship in Uganda. Her experiences in Uganda led her to stand against female genital mutilation; however, the process of female genital mutilation is still practiced today. During her college years, Alice Walker also visited Cuba on several occasions and would take an open political stand against the Cuban Embargos. Her political and social concerns were not strictly limited to the plight of black women in America but were on a global social and political scale (Bates, Alice Walker: A Critical Companion). After the publication of The Color Purple in 1982, Alice Walker would become a huge name virtually everywhere. The Color Purple would be turned into a movie and a Broadway play (Smith, Jessie). There was a great deal of controversy over the book because the black culture was shown as patriarchal and whites were shown as sexist and racist. The Color Purple looks head on at the situations and plights of the black woman without the worries of being politically or socially correct. The Color Purple was so powerful in character development and insights into issues that it won Alice Walker the Pulitzer Prize for Fiction in 1983. It would later also receive the American Book Award (Bates, Alice Walker: A Critical Companion). In 1992, she would o onto write the novel, Possessing My Secret Joy which would feature the characters that were descendants from The Color Purple. The Pulitzer Prize for Fiction was certainly the most distinguished of all her honors and awards but Alice Walker would go on to receive many others. In 1969 she received the Lillian Award from the National Endowment of the Arts for her publication of Third Life of Grange Copeland. In 1974, Walker received the Rosanthal Award from the Institute of Arts and Letters and the Radcliffe Institute Fellowship for the writing and publication of In Love and Trouble (Bates, Alice Walker: A Critical Companion). Even with all of her popularity, Alice Walker went on to write and publish such popular short stories and novels as You Can’t Keep a Good Woman Down: Stories in 1982, Beauty: When the Other Dancer is the Self in 1983, To Hell with Dying in 1988, The Temple of My Familiar in 1989, Finding the Green Stone in 1991, and Possessing the Secret of Joy in 1992 (Bates, Alice Walker: A Critical Companion). Walker continues to publish poetry collections as well. During her battle with Lymes Disease, Walker wrote The Same River Twice: Honoring the Difficult and a collection of political essays named Anything We Love Can Be Saved: a Writer’s Activism. Within three years she has written a further three books, By the Light of My Father’s Smile in 1998, The Way Forward is with a Broken Heart in 2000 and A Long Walk of Freedom in 2001. In light of the tragedy at the World Trade Centre in New York City, she wrote her most recent work: Sent by Earth: A Message from the Grandmother Spirit After the Bombing of the World Trade Center and the Pentagon (Bates, Alice Walker: A Critical Companion). Being an African American growing up in the United States during the 1950s was far from easy. There was segregation in most cities and whites fought against any chance of black freedom. However, by the 1950s, African Americans began to mobilize in earnest against discrimination. They lived in the same culture as white Americans and they wanted to enjoy equal rights. From the 1950s through the 1970s, movements for civil and social rights, equality, and justice swept the United States. Mainstream beliefs about the freedom of African Americans were challenged and protesters prompted the government to intervene and act on behalf of their equality principles. Activists were prominent in local marches, revolts, and peaceful protests that placed thousands of people on the national stage of a continental confrontation. However, people also witnessed major setbacks and difficulties over winning the white men’s approval of equal rights. Overtime, with the perserverence and determination of many human rights advocates, African Americans gained greater access to education and a much broader set of career oppurtunities. As for the justice system during the Civil Rights era, the landmark case of Brown vs. Board of Education of Topeka, Kansas upheld the activists demand to outlaw segregation in public schools (Brennan). Enacted in 1954, this major case symbolized the official start of the Civil Rights movement. A year after this ruling, the Montgomery Bus Boycott hit headlines across the country. Blacks were tired of giving up their seats to white people and being forced to sit in the back of the bus. It was then that Rosa Parks refused to move after the driver ordered her to allow a white man to sit down where she was. This sparked a mode of resistance in which this one-day boycott turned into a year long rebellion. Not one black person rode the Montgomery City Lines for 383 days (Brennan). At first the bus companies did not even press for compromise. Therefore, when they realized that nearly three-fourths of their customers were black, they were already quickly losing money. However, this did not stop organizations like the Montgomery Improvement Association from planning the next steps of boycott. At this point, popular leaders like Martin Luther King Jr. s well as Ralph Abernathy rose to become powerful leaders that would soon dominate the political scene when it came to question over equal rights (Brennan). When it came to peaceful protests, activists like King were arrested for their actions but quickly bailed out by their supporters to allow for the continuation of a steady fight. By 1956, the Montgomery Improvement Association and the National Association for the Advancement of Colored People(NAACP) attempted to end segregation of the city bus lines through the justice system. After months of legal dispute, the Montgomery City Lines were forced to end it’s policies on racial segregation on December 20,1956 (Brennan). As a result, the bus boycott ended the following day. Especially in the south, whites believed that any change in the social standings of society would disrupt the power balance between blacks and whites. Ultimately, they believed that if African Americans had any power whatsoever that resembled the whites, they would abuse it and revolt, trying to dominate southern society. Throughout the decade, black fears heightened as a result of brutal attacks from groups like the KKK and other gangs. In this time period, the KKK was experiencing its second resurgence since World War I and the popularity of lynching increased (Brennan). The inhumane morals of whites who lynched blacks was publicized in newspapers by journalists such as Ida B. Wells, who additionally worked for the Anti-Lynching Bureau (Brennan). It was no surprise that African Americans felt the need to be equal especially after they served in World War II. Nearly one million blacks served for their country during the 1940s and they believed that America was just as much of their country as it was the whites (Brennan).
