Reflection Of Sybil - 1496 Words
Sybil is about a woman who receives treatment over the course of 10 years for her multiple personalities. Part one of the book starts with Sybil in her chemistry classroom, the crash of glass makes her head throb. It takes her back to broken glass in the drugstore, and the broken glass in the big dining room. Both times there had been an accusing voice: ââ¬Å"You broke it.â⬠(Sybil pg. 23). At this time Sybil was not sure why she would disappear, and come to in random parts of the city, or states. She knew that every time she would black out she had to get as much done while she was still herself. New York was Sybilââ¬â¢s safe haven, not because she was away from her mother, but because Dr. Wilbur, her psychiatrist, was there. Dr. Wilbur made it aâ⬠¦show more contentâ⬠¦Hattie would also shove various objects into Sybilââ¬â¢s vagina, trying to justify her actions she would tell her men would do the same to her. Part three: Unbecoming, Dr. Wilbur brings Sybils father in, Willard, to discuss his marriage with Hattie. He realizes Hattie was the one responsible for Sybil being locked in the wheat bin. He now knows why Sybil screamed when the buttonhook was used on her shoes. He insisted that he had no knowledge of the abuse happening when he was gone, but he firmly believes that Hattie was capable of committing such horrific acts. By this time Dr. Wilbur has met Peggy Lou, Peggy Ann, Vicky, Mary, Marcia, Vanessa, Mike, Sid, Marjorie, Ruthie, Helen, Sybil Ann, Clara and Nancy. Sybil, however, has not met a single one. Sybil continues to lose time, with the others taking over. Dr. Wilbur tapes Sybilââ¬â¢s other personalities in hopes she will watch them so all of their memories will combine, and Sybil can become one. The tape brings back some of Sybils own memories about her mother and Willow Corners, and awakens something deep in her. She realizes that the others are real and not figments of her imagination. Part four, Reentry, After her suicid e attempt, Dr. Wilbur reluctantly gives Sybil sodium pentothal, which relieves Sybils anxiety but also unleashes some of Sybils repressed memories. The flood of memories shoves Sybil farther away from integration. She begins to recall some of the others and starts to realize thatShow MoreRelatedThe Art Museum s Gallery 71433 Words à |à 6 Pagesart history evident in 18th century Europe.

An Overview of Peace and Conflict Free Essays
AN OVERVIEW OF PEACE AND CONFLICT DEFINITIONS: Peace is often seen as the converse of war. i. e. We will write a custom essay sample on An Overview of Peace and Conflict or any similar topic only for you Order Now peace and war as two sides of the same coin. Hence the definition of peace as the absence of war, and that of war as the absence of peace The problem with this definition is that it does not explain everything about peace and war For example even in situations of war, some conditions of peace still prevail. E. g. in spite the long years of hostilities between the Israelis and Palestinians, both have been able to reach a peaceful agreement on the use of their water resources. Secondly, the definition does not take into account the issue of structural violence, in the words of John Galtung. According to Galtung, war represents only one form of violence, which is physical, open and direct. The others form of violence has to do with social conditions of life. This consists of â⬠¢Poverty â⬠¢Exclusion â⬠¢Intimidation â⬠¢Oppression â⬠¢Want â⬠¢Fear and â⬠¢Other forms of psychological pressure So from this analysis, it is possible not to have peace even where there is no war. This is the situation in countries where there is acute poverty, police brutality, oppression of the poor by the rich, use of power to intimidate people by those in power. Even where there is no war in such societies, they may not experience peace (Ibeanu) OTHER VIEW OF CONFLICT: â⬠¢Conflict as the pursuit of incompatible interests and goals by different groups â⬠¢Conflict occurs as a struggle over values. The values may be in terms of physical of material possessions or resources, status or power. (Louise Coser) â⬠¢Central to conflict is the issue of perception. When one party perceives the action of another as preventing or blocking the attainment of a goal, conflict is said to occur. Therefore the two ingredients necessary for conflict to occur are: ? Perceived goal incompatibility ?Perceived opportunity for interference or blocking. In other words, conflict occurs when an intended action is perceived to be inimical or detrimental to the realization of oneââ¬â¢s objective Generally perception is a product of manââ¬â¢s physiological, cognitive and cultural dispositions which of course differ from person to persons, and from one environment to another. Therefore, we can say that conflict is inevitable to the extent that it is fundamental to the existence of any institution, body or society It is inevitable because human beings are naturally different from one another in their attitude, perception and orientation. But conflicts could be destructive if not properly handled. Hence we often sat that the way and manner conflicts are resolved differentiates one organization or society from another. VARIOUS PERSPECTIVE OF PEACE â⬠¢To the Instrumentalists: Peace is a means to an end. Here the absence of war serves the objective of social progress and development. In other words, where there is peace, society will experience positive transformation in all facets of life. 2. TO THE FUNCTIONALISTS: Peace has a social function of integration and order. That peace is fundamental if society is to function properly. If not the social and political system will experience stress, and then brake down. 3. TO THE PHILOSOPHERS: Many philosophers interpret peace as a natural, original, God-given state of human existence. i. e. , the pre-corruption state of man in society, as God established it. This is the Godââ¬â¢s created state of perfection. EXAMPLES OF PHILOSOPHERS â⬠¢St. Augustine of Hippo: He distinguished between ââ¬Å"two citiesâ⬠, namely; The city of God, founded on perfect heavenly peace and spiritual salvation; and the Earthly city of man, founded on acquisition and possessive mentality of man, but corrupt and always in conflict. â⬠¢John Rousseau: He sees from the angle of a state of nature, the original state of existence of man where there are no desires, where men were naturally good, free and enjoy tranquility. But this atmosphere was corrupted by human desire and greed for private property â⬠¢THOMAS HOBBES His argument was that peace is a product of the state of nature where life was poor nasty, brutish and short, and where society was in a state of perpetual war. For men to overcome this sorry state, they resolved to establish a social contract in which each gave up his/her right to self defiance to powerful force (what he called the leviathan) above all to which all were subject, thus creating a more peaceful and orderly life â⬠¢THE HEDONISTS AND UTILITARIANS Argue that human beings naturally seek happiness and avoid pain, and consequently prefer peace to war and violence. PLATO: He addresses the social context of peace. He sees justice as the most fundamental basis of ordered social life. For him, justice is the basis of peaceful social life. Justice is given to each his or her live. Plato defines society in terms of three classes of people: ââ¬â Workers ââ¬â engaged in production ââ¬â men of appetite ââ¬â Soldiers ââ¬â defend the society ââ¬â men of cour age -Rulers ââ¬â Govern the society ââ¬â Men of Knowledge Each must operate within his area of competence, and where this does not operate, he sees injustice â⬠¢SOCIOLOGICAL PERSPECTIVE OF PEACE The Sociologist also addresses the social context of peace â⬠¢The Sociologist sees peace as a condition of social harmony, the absence of social antagonisms â⬠¢Peace to the sociologist, is a condition in which there is no social conflict and individuals and groups are able to meet their needs and expectations This is achieved through the establishment of structures to perform certain basic functions of society; for example a society must service, it must educate it citizens, produce goods government and its often provide security for its members. To achieve these structures such as schools, industries, parliaments, courts and armed forces are established. â⬠¢Therefore to the sociologists, peace is achieved where these structures perform their functions adequately â⬠¢TO THE MARXISTS: â⬠¢Conflict is a product of dialectical materialism â⬠¢It is a product of the structure of rewards in the society â⬠¢It is a reflection of the nature of class and class struggle â⬠¢This breeds a struggle for the control of the means of production in the society â⬠¢The result of the attendant inequality is in two folds; Violence perpetrated by the upper class on the oppressed ââ¬â Violence engineered by the oppressed against the ruling class ââ¬â revolutionary violence. Hence the phrase ââ¬Å"Those who make peaceful change impossible make violent change inevitableâ⬠â⬠¢Political Perspective of Peace â⬠¢Politically peace is synonymous with political order when the political structures are stable, we talk of peace in the society: â⬠¢Peace is also seen as a political condition that makes justice possible. The colapse of the political structures lead men to seek other route to enforce their will. These may be in the form of Mob action, demonstration, strikes or even military coups To ensure peace therefore the political structures must be stable and effective to extent that they perform their role. Politically, these must guarantee citizens participation in the political process; ensures tolerance of opposing views; and encourage bargaining and negotiation. Also politically speaking, peace suggests that government does not rely on coercion and the instruments of force (such as army, police) in dealing with citizens Instead people willingly accept and obey the dictates of government Peace in this sense connotes mutual consent and agreement to respect the rules governing a society whether locally or internationally. But the question is whose order? Must every political order be sustained just to ensure peace (e. g. The Nazis, Mobutus, Abacha) How to cite An Overview of Peace and Conflict, Essay examples

Telehealth Ubiquitous Computing Bandwidth -Myassignmenthelp.Com
Question: Discuss About The Telehealth Ubiquitous Computing Bandwidth? Answer: Introduction Telehealth is a project that is introduced for improving the process of providing healthcare services in rural public hospitals. This project is to deliver a high quality heath service irrespective of the geographical barrier. Telehealth is software that operates in a real time basis, and is a cost effective solution. It is an alternative to the traditional way of offering the healthcare services (Steele Lo, 2013). The use of this Telehealth software is expected to improve the patients outcome and driving greater efficiency in terms of the ways in which the healthcare services are delivered. This software will link all the emergency department of the nearest hospitals with the help of videoconferencing with an aim of delivering 24*7 emergency services in the rural areas as well. Use of a cloud-based solution in the software is an effective way of accessing and storing all the records of the hospitals and the patients (AlZain, et al., 2012). The report discusses various aspects of th e using a cloud based solution in the project. Non-Functional Requirements A systems non-functional requirements help in identifying the requirements that judge the vital operation of a system. This includes the system requirements, hardware or software requirements, and constraints. Functionality Functionality is an important aspect in identifying the non-functional requirements of Telehealth project as it analyzes the needs of the customers (Jain Nandakumar, 2012). The major non-functional requirement is ensuring the proper security of the Telehealth system. This is essential to improve the security of the customers data stored in the system. Furthermore, since the system is to be generated for linking all the management departments of the hospitals, it is essential to consider the throughput of the system. A system development with high throughput is therefore, another non-functional requirement. Usability The non-functional requirement associated with the usability of the system determines how effective the product is from a users point of view. Since the project is to be developed for providing emergency healthcare services to the people of rural areas, the user interface should be simple and easy to use. Furthermore, the users of the system should be able to access and use the emergency services without any hazards and therefore, it is essential to implement a system that comes with proper step-by-step guidance about its operation. Reliability The system to be implemented should be reliable enough so as to provide and uninterrupted emergency services to the people in rural areas. Therefore, having an option of data backup and recovery is an essential non-functional requirement. Since the system is to be implemented on cloud, it will not be an issue to enforce a proper disaster recovery option for implementation of a reliable Telehealth system. Performance The project is very important and crucial as it aims at delivering a system that will link all the emergency healthcare centers across the rural region and provide emergency services to the patients via video conferencing. The After-Hours Urgent Care Telehealth project should therefore provide uninterrupted services to its clients. Ensuring a minimum response time of the system to be developed is therefore and important non-functional requirement. Another advantage of implementing the system in a cloud platform is an increased memory space of the system, which is another major non-functional requirement. Supportability The proposed system is a completely new venture. Therefore, important non-functional requirements of the project include testability, extensibility, serviceability and configurability of the system. The After-Hours Urgent Care Telehealth system should support all these non-functional requirements of the system (Krupinski Bernard, 2014). Apart from these main non-functional requirements, the project should further consider the design constraints, implementation requirements and physical requirements of the system. Functional Vs Non-Functional Requirements A system cannot be implemented without considering the functional requirements of the system unlike the non functional requirements. Ensuring proper security needs is another major function requirements. The Telehealth should be secure for storing a sensitive data of the patients. In order to ensure implementation of a secure system, proper authentication and authorization levels are to be enforced in the system for eliminating the risk of unauthorized data access. Therefore, authentication is one of the major functional requirements of the project. Non-Functional requirements of the system on the other hand ensure smooth operations of the system (Chung et al., 2012). Both functional and non functional requirements are needed to be considered for proper system implementation. The cloud based solution: Hybrid Cloud Environment The project aims at providing emergency healthcare services to the customers and therefore, ensuring proper security and confidential of the patients data is a major functional requirement of the system. The cloud environment chosen for implementation of the After-Hours Urgent Care Telehealth is hybrid cloud environment. This is because the hybrid cloud environment provides certain additional benefits over the private and public cloud environment. The use of public cloud environment would not be suitable for this project. This is because the project links all the emergency departments of the nearest hospitals via video conferencing. Therefore, this will include storage of confidential data of the patients and the hospital. Since the pubic cloud is accessible by all, it is very vulnerable to attacks (Chen Zhao, 2012). Therefore, implementation of Telehealth project in public cloud environment is not an effective idea. Implementation of the system in a public cloud environment however could have been a cost effective solution. The private cloud environment on the other hand provides a distinct and a secure cloud solution (Galibus Vissia, 2015). However, there are certain constraints associated with the implementation of this project in a private cloud environment. The major drawback of using private cloud is that for increasing the security essentials of a system, private clouds allows only a specified client in accessing the information stored in the system or operating the system. If the After-Hours Urgent Care Telehealth project is implemented in a private cloud environment, it will constrict the accessibility of the system. Furthermore, the cost of implementing a system in a private cloud is higher in comparison to the public cloud as it requires an installation of a dedicated network for a particular system for enhanced security (Li et al., 2013). Therefore, it is not recommended to implement the project After-Hours Urgent Care Telehealth in a private cloud environment. Hybrid cloud consists of the features of both public and private cloud environment. Hybrid cloud ensures proper data security and therefore patients as well as hospital data can be securely stored in the system. Since hybrid-cloud consists features of both public and private cloud, the private network of hybrid cloud ensures data security while the public network increases the accessibility of the system (Li et al., 2015). Therefore, it is recommended to implement the project in a hybrid cloud environment. Strength The strengths of hybrid cloud are as follows- The hybrid cloud environment ensures proper security and confidentiality of the data. Therefore, use of hybrid cloud in system implementaion would be beneficial for protecting the privacy and confidentiality of the data stored in the system (Kulkarni et al., 2012). Use of hybrid cloud in implementation of the system will be a cost effective solution for the organization. The public network of the hybrid cloud can be leveraged from a service provider that will in turn reduce the total IT equipment cost of the project. The hybrid cloud environment provides easier and secure access to the stored datain the system. Therefore, it is safe to implement the Telehealth project in the hybrid cloud environment. Weakness The data movement to and fro of the public and private cloud is vulnerable to outside attacks. Attackers can target this data movement in order to steal the confidential information stored in the system. The implementation cost is grreater than that of implementing the system in a public cloud environment. The sensitive and confidential nature of the patients data can be therefore be kept secured by using proper authorization and encryption for managing The chosen SDLC Approach: Predictive SDLC The SDLC or software development life cycle approach is an important consideration in implementation of a software. SDLC approach defines the stages involved in development or implementation of a software. The details about predictive and adaptive SDLC are as follows (Balaji Murugaiyan, 2012)- Predictive SDLC Predictive SLDC approach provides a detailed overview of the stages involved in implementation of a project. Therefore, in this approach the all the stages of project development are pre planned before the project reaches its execution phase. Predictive SDLC model can therefore be used in project implementation that has a predetermined and clear scope and requirements. The scope of the project implemented using predictive SDLC approach however, cannot be modified once the project reaches its execution phase (Mahalakshmi Sundararajan, 2013). The pros of using a predictive SDLC in implementation of this project are as follows (Rittinghouse Ransome, 2016)- Predictive SDLC approach ensures completion of the project within the scheduled time. Since the phases of the project are pre determined, it becomes easier to track the project progress. The budget estimation of the project becomes easier and accurate as the project requirements remains clear since the project initiation phase. It becomes very difficult to make modifications in the project while its implementation The feedback path is generally absent in predictive SDLC. Adaptive SDLC Adaptive SDLC unlike predictive SDLC does not define the entire project in the initiation phase. The schedule of the project can be modified while the project execution. The pros and cons of adaptive SDLC are as follows (Tuteja Dubey, 2012)- The project does not follow a fixed schedule or plan and therefore project improvement becomes easier. Presence of feedback path helps in big fixing prior to the deployment of the system There remains a risk of project not being implemented within the set schedule Budget of the project remains inconsistent. Therefore, it is recommended for this project to use a predictive SDLC approach as the requirements and scope of the project is clear. Conclusion Therefore, it can be deduced that the Telehealth project should implement the system in a hybrid cloud, as it will provide proper data security. Furthermore, the project needs to be implemented using predictive SDLC approach for ensuring the project completion within scheduled time. Since the scope and requirements of the project is clear, predictive approach will be best for implementing the project. References AlZain, M. A., Pardede, E., Soh, B., Thom, J. A. (2012, January).

Balance Redox Reaction Example Problem
Balance Redox Reaction Example Problem When balancing redox reactions, the overall electronic charge must be balanced in addition to the usual molar ratios of the component reactants and products. This example problem illustrates how to use the half-reaction method to balance a redox reaction in a solution. Question Balance the following redox reaction in an acidic solution: Cu(s) HNO3(aq) ââ â Cu2(aq) NO(g) Solution Step 1: Identify what is being oxidized and what is being reduced. To identify which atoms are being reduced or oxidized, assign oxidation states to each atom of the reaction. For review: Rules for Assigning Oxidation StatesAssigning Oxidation States Example ProblemOxidation and Reduction Reaction Example Problem Cu(s): Cu 0HNO3: H 1, N 5, O -6Cu2: Cu 2NO(g): N 2, O -2 Cu went from oxidation state 0 to 2, losing two electrons. Copper is oxidized by this reaction.N went from oxidation state 5 to 2, gaining three electrons. Nitrogen is reduced by this reaction. Step 2: Break the reaction into two half-reactions: oxidation and reduction. Oxidation: Cu ââ â Cu2 Reduction: HNO3 ââ â NO Step 3: Balance each half-reaction by both stoichiometry and electronic charge. This is accomplished by adding substances to the reaction. The only rule is that the only substances you can add must already be in the solution. These include water (H2O), H ions (in acidic solutions), OH- ions (in basic solutions) and electrons. Start with the oxidation half-reaction: The half-reaction is already balanced atomically. To balance electronically, two electrons must be added to the product side. Cu ââ â Cu2 2 e- Now, balance the reduction reaction. This reaction requires more work. The first step is to balance all atoms except oxygen and hydrogen. HNO3 ââ â NO There is only one nitrogen atom on both sides, so nitrogen is already balanced. The second step is to balance the oxygen atoms. This is done by adding water to the side that needs more oxygen. In this case, the reactant side has three oxygens and the product side has only one oxygen. Add two water molecules to the product side. HNO3 ââ â NO 2 H2O The third step is to balance the hydrogen atoms. This is accomplished by adding H ions to the side that needs more hydrogen. The reactant side has one hydrogen atom while the product side has four. Add 3 H ions to the reactant side. HNO3 3 H ââ â NO 2 H2O The equation is balanced atomically, but not electrically. The final step is to balance the charge by adding electrons to the more positive side of the reaction. One the reactant side, the overall charge is 3, while the product side is neutral. To counteract the 3 charge, add three electrons to the reactant side. HNO3 3 H 3 e- ââ â NO 2 H2O Now the reduction half-equation is balanced. Step 4: Equalize the electron transfer. In redox reactions, the number of electrons gained must equal the number of electrons lost. To accomplish this, each reaction is multiplied by whole numbers to contain the same number of electrons. The oxidation half-reaction has two electrons while the reduction half-reaction has three electrons. The lowest common denominator between them is six electrons. Multiply the oxidation half-reaction by 3 and the reduction half-reaction by 2. 3 Cu ââ â 3 Cu2 6 e-2 HNO3 6 H 6 e- ââ â 2 NO 4 H2O Step 5: Recombine the half-reactions. This is accomplished by adding the two reactions together. Once they are added, cancel out anything that appears on both sides of the reaction. à à à 3 Cu ââ â 3 Cu2 6 e- 2 HNO3 6 H 6 e- ââ â 2 NO 4 H2O 3 Cu 2 HNO3 6H 6 e- ââ â 3 Cu2 2 NO 4 H2O 6 e- Both sides have six electrons that can be canceled. 3 Cu 2 HNO3 6 H ââ â 3 Cu2 2 NO 4 H2O The complete redox reaction is now balanced. Answer 3 Cu 2 HNO3 6 H ââ â 3 Cu2 2 NO 4 H2O To summarize: Identify the oxidation and reduction components of the reaction.Separate the reaction into the oxidation half-reaction and reduction half-reaction.Balance each half-reaction both atomically and electronically.Equalize the electron transfer between oxidation and reduction half-equations.Recombine the half-reactions to form the complete redox reaction.

Why the operational level labour motivation is low in SkillsFootwear Dissertation
Why the operational level labour motivation is low in SkillsFootwear - Dissertation Example Moreover, according to Lloyd (2005, pp.929 ââ¬â 943) the firmââ¬â¢s competitive advantage was its skilled labor and workmanship as the products were fully handmade. The organization had a total of 110 employees who reported to their middle level managers who reported to the entrepreneur thus having a comparatively flat organizational hierarchy. The operational level workers were on daily wages, which were the industry average rates. The management however received monthly wages. The Sri Lankan shoe industry has a total of 30 medium scaled and 3000 small-scaled manufacturers. The industry produces a wide range of shoes from canvas, sports and leather shoes and is also exporting finished products to EU and USA. As per a research done by the Development of Board Sri Lanka, the shoe industry witnessed a decline from 2007 onwards but the 2010 witnessed a surge in the export market due to the growth in the local tourist sector. However, the workforce in the industry is n issue. This is because the skill is making shoes completely by hand. But this is a difficult task and most firms have not incorporated technology into the process of production, which is not very lucrative for the workmen. According to Lloyd (2005, pp.929 ââ¬â 943), this is because their production level is low and the firm cannot deliver larger orders and often cannot meet deadlines. Thus the craftsmen are not given enough bonuses and motivations. This in turn has caused the workers to drift away from the skill and the skill is not being handed over to their children. Moreover, the basic pay scale, recognition in society and the living standards of these workmen are not high which is yet again a de-motivating factor. The skill of these workers is safeguarded neither by the industry people nor by the government and this is a threat to the industry. Adding to this, there is not enough training and technology in the footwear industry especially in the SME sector. 2.2 Motivation The motivatio n level of the workers in the footwear industry of Sri Lanka is generally low. This is because the government and the industry have not given it enough importance, as they do not realize the power of labor. There is underproduction in the industry and it is primarily due to the fact that the labor are not working at full capacity nor are they receiving state of the art training in technological advancements. According to Lloyd (2005, pp.929 ââ¬â 943), motivation is the essence and the core of management and is an effective tool to make the labor force perform more meaningfully. Motivation is important to produce the drive in a labor to give his 100% when he is working. Without motivation, a worker with the potential to produce 100% may not be able to do so as he doesnââ¬â¢t have the drive to do so. According to Hofstede (2005),

Management - Essay Example Figure 1 shows how this disruptive model works. The focus of this paper is to ascertain the secrets of success in sustaining long-term performance and growth; in essence, how to become an innovator. In MGT class, we have asserted that it is no simple matter for a firm to be a long-term innovator and that accomplishing this requires capable performance in corporate strategy, culture, architecture, leadership and decision making (taken from topic question). During the process of researching this paper, the realization I came to is that sustainable growth comes from many different factors but they are all under one subheading: This one heading encompasses the myriad of topics that were and still are discussed in MGT. These areas also contain the seeds of creating sustainable growth and innovation in companies. I will discuss how these areas manifested in various companies for their betterment or their detriment. My position is that I agree with Christensen and Raynor in that disruptive sustainable growth, while not yet fully experienced by any company to date (except possibly for Microsoft), is within the realm of possibility. Sustainable growth and innovation is a product of one seamless thread of business concept and application from top to bottom. How this thread is severed can come from many different areas, one of the most important being from the management team level. Executives are charged with the task of creating profit in various business and product lines within their companies. How does a manager allocate his time and resources to do this? For me, the concept of disruptive growth is a Rosetta stone in this topic. To me, it holds within it the essence of growth and success along with chaos theory. These two concepts create a complexly rich look at how managers can conceptualize and manage their businesses without forcing control onto their businesses.
