Booker T Washington: Fighter for the Black Man

Booker T. Washington was a man beyond words. His perseverance and will to work were well known throughout the United States. He rose from slavery, delivering speech after speech expressing his views on how to uplift America's view of the Negro. He felt that knowledge was power, not just knowledge of â€Å"books†, but knowledge of agricultural and industrial trades. He felt that the Negro would rise to be an equal in American society through hard work. Washington founded a school on these principles, and it became the world's leader in agricultural and industrial education for the Negro. As the world watched him put his heart and soul into his school, Tuskegee Institute, he gained great respect from both the white and black communities. Many of the country's white leaders agreed with his principals, and so he had a great deal of support. Booker T. Washington was a great man. He put his own needs aside in order to build the reputation of an entire race. He didn't do it by accusing and putting blame on others, but instead through hard work. Booker T. Washington cleared the way for the black community to fully enter the American society. Washington was born into slavery on April 5, 1856, in Franklin County, Virginia, on a small tobacco plantation. His only true relative was his mother, Jane, who was the plantation's cook. His father was probably the white son of one of the neighbors, though it is not known for sure. Washington spent his childhood years on the plantation, but since he was so young he never had to do the heavy work. He did the small jobs, such as carrying water to the field hands and taking corn to the local mill for grinding. This hard work at an early age instilled in him the values he would teach for the rest of his life. When the Civil War ended in April of 1863, Washington and his mom were set free. Unlike most of the other slaves, Washington had somewhere to go. His step-father had escaped earlier, and had gotten a job in Malden, West Virginia, at a salt furnace. When the war ended, he sent for Washington and his mom. Life was tough in Malden. â€Å"Drinking, gambling, quarrels, fights, and shockingly immoral practices were frequent.† Washington himself got a job in the salt furnace and often had to go to work at four in the morning. Washington longed for an education. A school for Negro's opened in Malden, but his step-father would not let him leave work to attend. Washington was so determined to get an education that he arranged with the teachers to give him classes at night. He was later allowed to attend in the morning, but would then work all afternoon and into the evening. Booker did not have a last name until he went to school. â€Å"When he realized that all of the other children at the school had a ‘second' name, and the teacher asked him his, he invented the name Washington.† A great influence on Washington was Viola Ruffner, the wife of the owner of the salt furnace. Washington became her house boy, where he learned the importance of cleanness and hard work, and pride in a job well done. He would use these principles for the rest of his life. â€Å"The lessons I learned in the home of Mrs. Ruffner were as valuable to me as any education I have ever gotten anywhere since,† he later commented. Booker heard of a big school for Negro's in Hampton, Virginia, and he decided to go there. In 1872, at the age of sixteen, he set out on the 400 mile journey to Hampton, traveling most of the way by foot. When he finally arrived, he was so ragged and dirty that he almost wasn't admitted, but he was so persistent that they finally caved in, and he was allowed to attend. He studied there for three years, working as a janitor to pay his board. At Hampton, Washington participated in the debating society, which helped him develop a talent for public speaking. He used this talent many times throughout the rest of his life. In 1875, he graduated with honors and returned to Malden, where he taught elementary school. Two years later he went to Wayland Seminary, in Washington, DC, where he studied for eight months. He then was asked to come back to Hampton to be an instructor. In May, 1881, the principal of Hampton received a letter from a group in Tuskegee, Alabama, asking for help in starting a school for Negro's there. They were expecting a white man, but when they got Washington, they were quite pleased with him. On July 4, 1881, at the age of twenty-five, Washington founded The Tuskegee Normal and Industrial Institute. The State of Alabama had sent $2,000 for the teachers' salaries, but had sent no money for land, buildings, or equipment. The school opened with 30 students. Most of them had some prior education, but they did not appreciate household cleanness, which was so valued by Washington. He wanted on-campus dormitories so he could supervise and improve the students' living habits. The school found an abandoned farm nearby, but it had no buildings fit for living or teaching in. Washington and his students raised enough money for construction, and they built the first brick building. They also built a kiln to make bricks for future projects as well as to manufacture and sell to others. Tuskegee Institute and its facilities grew, and so did its courses in agricultural and engineering subjects. The Institute survived its early years only through the perseverance of Washington. In the second month of the school's first year, Olivia Davidson joined Washington as his assistant. She was also a graduate of Hampton and of a Massachusetts normal school. She was not only Washington's assistant but also a teacher at the school. She would later marry Washington. â€Å"No single individual did more toward laying the foundations of Tuskegee Institute so as to insure the successful work that has been done there than Olivia A. Davidson.† Washington believed in the â€Å"dignity of labor.† He emphasized the teaching of â€Å"practical skills,† like brickmaking, carpentry and dairying for the boys, and cooking and sewing for the girls. He believed thatNegro's must make economic progress, and learn how to make a living first. In order to raise funds for the school, Washington traveled all over the country, giving hundreds of speeches expressing his ideas and explaining his program at the school. He became known nationally because of these speeches, which led to many contributors such as Andrew Carnagie, John Rockefellar, and Collis Huntington. As for Tuskegee Institute, its success was beyond Washington's wildest dreams. At the time of Washington's death, 34 years after its founding, the school property included 2,345 acres and 107 buildings, with nearly 200 faculty members and more than 1,500 students. Tuskegee Institute had become the world's leader in agricultural and industrial education for the Negro. Booker's spirit and name live on long after his death. He is remembered and admired for his struggle for the black man. Tuskegee Institute still exists today and is quite well off, with over 3,250 students, about 5,000 acres, and an annual budget of $75 million. Booker T. Washington is a wonderful example that even if you came from nothing, you can accomplish great things if you try hard enough and are willing to make the sacrifice.

Has UK become a digital nation?

Abstract Information Technology has become more prevalent making it indispensable in the day to day activities of not just individuals or businesses but to the nation as a whole. There are more government initiatives to move from paper-based record keeping to a digital record management. However, despite technology growth, the nation as a whole is not prepared to get accustomed to a digital world. Though technology simplifies certain key processes and tasks in our day to day lives there are still areas like training and development that the nation needs to tackle in order embrace the digital revolution. The key aim of this review is to understand the key role of information technology and information systems in business, public sector and in the lives of the common man and the evolution of technology and its use in various areas. The review critically analyses research about internet and other emerging technologies and points out the current gaps. Introduction The rapid development of information technology and tools has not only made it easier for individuals and businesses to work at their own convenience and obtain information faster, but has also shrunk the world into a global village. Information Systems and Technologies have now become the backbone and lifeblood of businesses. In an information age, almost all processes are automated by businesses, most transactions take place over the internet and businesses use information technology in some way or the other. The Office for National Statistics (2013) have shown that there has been a sharp increase in the usage of internet for business activities. From using internet as a primary means of communications, businesses are now increasingly using internet for making sales online. The statistics show that 18% of the business turnover was accounted for by online sales and nearly 43% of businesses in the UK used social media to market their products and promotional activities. Studies by Business Zone (2011) showed that 77% of the households in the UK have access to the internet and that the growth in the Information and Communication Technologies (ICT) has the potential to generate ?35 million value added growth in the UK economy by businesses. In the digital technological age, businesses and nations have two options to either embrace the technology or be a technologically divided nation. Technology has become ingrained in the lives of the modern man and has proven to have significant advantages and benefits. The last four decades have shown a stark increase in the development and usage of technology. Businesses that do not have technological expertise miss out on opportunities, individuals find it difficult to carry on even the most mundane tasks without technological assistance as dependence on technology increases but technology enables information to be available at any time that helps organisations take strategic decisions (Melville et al, 2004) The main aim of this paper is to identify the role information systems play in organisations and to critically review the literature to get an in-depth understanding of the IT trends and infrastructure evolution in order to understand whether the UK has become a digital nation. Literature Review This section discusses the role of Information Systems in business organisations, the infrastructure and key technological developments over the past few years and also the role of internet in the digital and modern age.Information Systems in BusinessStudies show that information systems are being used by businesses in order to increase productivity, decrease costs, and effectively manage their day to day operations thereby increasing profits (Melville et al, 2004). Information Technology and Information Systems are no longer a separate department in an organisation but a cross-functional one which has a role to play in the overall business, thus making it inevitable (Rainer and Cegielski, 2010). In their book, Enabling and Transforming Business, the authors (Melville et al, 2004)discuss the role information system plays in not only developing the business but also as a key role it takes in facilitating the business to reach its strategic and long-term goals and vision. The authors d iscuss the power of digital information and the real-world applications of Information Technology in a business environment. The authors show that IT solutions can be applied to any business problem in order to maximise the returns and also to ensure that an effective solution is maintained. This is not just true to business organisations. In a digitised world, governments also apply Information Technology to make information available and to use IT and information systems to process, store and disseminate information to enable faster processing, reduction in costs, improved practices and complying with various regulations .(Rainer and Cegielski, 2010).There is an undeniable and key role that Information Technology plays in business organisations that it is almost impossible for businesses to function without IT support. This does not mean that using IT would lead the organisation to success. The authors point out by means of case studies and examples where using IT can actually lea d to the failure. This points out to the areas that need to be concentrated on while implementing an IT solution within the business or the key points that need to be considered while deciding to digitise the business to ensure that the IT implementation helps the business achieve its objectives. This book provides all the basic pointers that need to be noted while implementing an information system and takes the reader through the importance `and advantages of the same. This book however cannot act as a final guide for choosing appropriate technologies or for advanced readers. Businesses in this information age are moving to global web-based platforms to be able to appeal to more customers. Internet and other emerging technologies, such as wireless and mobile communication systems, further enhance their business offering and also for competitive and strategic advantage (Bocij, 2006). Organisations use information systems for provision of business intelligence that would enable them be in the forefront (Negash, 2004). Studies relate good organisational performance with a strong information systems and infrastructure. Information technology has a great impact in the performance of the company and helps to add value to the services offered. However, researchers show that in order for the information technology to be able to add value and help in the significant contribution of the success of the business, it is essential a good framework is being used to develop the IT business model, training needs are adhered to and that a proper change management mechanism is in place. (Melville et al, 2004). From the above, it can be noted that information systems in business is inevitable and even government organisations are adapting and embracing new technologies thus driving forward the digital age and making a contributing to drive the nation to go digital.Emerging TechnologiesInformation Technology is developing and evolving at a rapid pace. Technology is no longer just a personal computer or a network of computers. Gartner (2013) predicts the top technologies include mobile device management, mobile apps and applications, cloud computing, smart machines and 3-D printing in 2014. MIT technology (2014) discusses that future holds a lot more breakthroughs in technologies. The most fascinating and powerful technologies that would dominate the current year are noted as ultraprivate smartphones built with security and privacy, 3-D printing, neuromorphic chips that act like brain chips and mobile collaboration. The research shows that these technologies take the digital age to a whole new level and that helps businesses become and remain more competitive and also take provision of services to a whole new level. Powerful and modern technology would enable businesses to operate and collaborate in a better fashion. These emerging technologies show that the scope of technology has gone beyond just using of computers and how technology if used properly can help steering forward the digital era and also the impact it can make on business as well as the entire population.Internet in BusinessInternet in business is gaining more and more importance and the proliferation of this technology has made communications seamless across the globe. The Internet started out as a communication technology and now has become indispensable to the business not only for communication but also for various other purposes (Afuah, 2000). Internet is increasingly used as a tool to collaborate, make sales, communicate with customers, build brand image and as an economically viable channel to advertise and reach out to a larger population of customers (Zhao, 2000). Internet commerce or e-commerce facilitates processing of transactions online using internet technologies. The development of these technologies and the proliferation of these has enabled businesses to sell their products directly to the customers irrespective of their geographic location. This technological era has not only changed dramatically but has also led to the change in perspective in terms of business models and the way businesses and corporations operate and engage with customers. The emergence of social media sites on the internet enables businesses use these to be able to pitch their ideas and attract a plethora of customers, build trust and a brand image. Similarly, using internet technologies has enabled effective communication across the globe irrespective of the time zone and to be able to obtain information across the globe at convenience. Overall this has marked the rapid growth in using technology as a means for development and making a significant impact in the digital world.Benefits of ITStudies show that UK digitisation has had a very positive impact in the economy and has added nearly ?63 billion to the annual GDP. The other benefits of IT in the general population and the economy includes: Better living quality by minimising efforts and increasing efficiency of services offered. Internet proficiency can help government to meet its goals and also streamline various processes. (UK & Booz & Co, 2012) Businesses can collaborate better and use its online presence to market its products and services.Key Information Technology ChallengesThough internet and other Information and Communications Technologies have become more prevalent and common in businesses today, there are still various organisations that face various IT implementation challenges. These include: 1. Moving from paper-based environment to electronic records: Studies show that more than 90% of the businesses use electronic records. However, moving from paper based to electronic environment could be quite challenging. Businesses would need to be able to find the correct records management software and technologies to support their processes and manage business records digitally and this is difficult because of the lack of key skills and expertise in understanding the various tools and services that are offered. This process could be further complicated by various compliance laws that might become applicable whilst moving to electronic records, organisational culture and change management procedure in place to handle these (M Rapaport, 2014). Training: When implementing new technologies it is imperative that staff are trained. Implementing new technologies might cause reluctance in employees using these due to lack of knowledge, skills and expertise. It is imperative that businesses use good training methods and have adequate change control to ensure business-wide acceptance of the technologies (E Savitz, 2011). Security: Security is a key issue and data protection and privacy are areas of concern for enterprises. Systems and technologies are under various threats and risks and it is therefore essential for businesses to think through the information security challenges, authentication and authorisation methods, policies, compliance and regulatory requirements whilst implementing IT within the business (Symantec, 2014). Conclusion All businesses and individuals are using information technology more and more. Government departments are also moving towards electronic data and technology has now become a part and parcel of all organisations. However, this development has a lot of challenges and businesses need to cross a lot of barriers before implementing the correct information system and technology. Training and acceptance of technology has to be taken into consideration while implementing Information systems across the organisation. There are various advantages of using IT and affiliated technologies. The key challenges facing the government adapting to technology is ensuring cost effectiveness and having a fully transparent procedure that is auditable. Moving to a digital age can make certain things challenging; however, the benefits of implementation of technologies outweigh the challenges. The current trend shows that there would be an increase in the technological proliferation and for government to embrace the technology fully it requires that the skills gap be catered to and that ICT literacy is taken into consideration by the government. To become a digital nation, substantial investment is required and the adequate skills needed to be able to support the infrastructure and the technology are essential. The costs for such an emergence needs to be taken into consideration and the necessary measures need to be taken to be fully prepared to embrace the technological age with ease. This review has shown that there are various benefits of using Information Technology and has also shown evidence of the usage of Information Technology by businesses and the government. This clearly shows the steps and the contribution to move to a digital era. It also highlights the key challenges faced and these challenges if tackled effectively would lead to harnessing all the key benefits of technology thus making UK a truly digital nation.

Transgenic Plants and Animals Essay Example | Topics and Well Written Essays - 1000 words

Transgenic Plants and Animals - Essay Example Transgenic plants can help in the area of food sufficiency, through production of high yielding crop varieties; improving plant tolerance against extreme conditions such as drought or floods; increasing resistance to pests; and increasing resistance to herbicides. These improvements would reduce production cost, reduce wastage, increase yield per hectare and thereby increase food availability. Today, varieties of peanuts and corn resistant to pests are already grown throughout the world. In health, genetic modifications can aid in making life saving drugs in large amounts. Transgenic livestock that produce recombinant proteins in their milk can provide an economic and safe system for production of valuable proteins, such as pharmaceutical proteins for treatment or prevention of human disease or biomaterials for medical use (Keefer, 2004). As an example insulin and the clotting factors are made by human systems. If we insert the gene that is capable of producing insulin from humans into cows in the right way, then we can get the cows to produce the insulin or clotting factors in their milk. Then we have a potential mass producer of insular greater than human is capable of doing. In the areas of nutrition, common staple crops like rice, corn, root crops, and others can be modified to produce varieties high in necessary nutrients. In the area of environment, organisms can de modified to degrade non-biodegradable plastics and other materials and make them more useful to the environment. Major concerns on transgenic plants and animals The production of transgenic plants and animals has faced several concerns among conservatives in Europe, America, and almost every corners of the globe. Thro (2004) emphasized that there are conflicting views about the idea... The researcher states that recent development in biotechnology that gains attention in the scientific world is the alteration of genetic components of plants and animals. The process involves adding and integrating foreign genetic material into the genetic structures of the plants and animals. Transgenic technology affords methods that allow the transfer of genes between different species. The produced organism is generally called as GMO or transgenic plants or animals. A transgene is a gene with desirable characteristics that is moved from a source organism implanted into a new organism in order to improve the desired characteristics of the recipient organism. This is an improvement from the traditional process of breeding wherein a plant or animal with a desired trait is mated with an existing plant or animal of the same type, to transfer the desired trait to the offspring. The limitation of this old method is that the only genes that are involved are the genes already present in t he parental plants or animals. For example, if you bred dogs, you get dogs with genes coming from both dog parents and nothing else. In genetic modification, genes from plants can be integrated into animals or vice versa; genes from birds can be integrated with horses. Production of transgenic plants is expensive and complicated since it uses costly technology and facility. Companies producing GM seeds in countries such as the US desire to produce more revenues on them because they put a lot of resources into making them.

Construction Safety Assignment Example | Topics and Well Written Essays - 250 words - 12

Construction Safety - Assignment Example There is need therefore to have a way of applying these in such a large project with many contractors. All contractors need to come together and establish compliance standards that revolve around waste management, hazards avoidance measures, spill management and cleanups etc. Contractors are supposed to ensure monitoring is done as routinely as possible (Chen and Li, 2006). This ensures that the standards are being followed: this can be through a neutral Site Inspector. Workers need to be trained together on the environmental safety and ISO standards to be upheld at the site. The contractors need to demand to know the construction safety record of fellow contractors so as to ensure that safety of their workers is not to be compromised. This way, only competent contractors are to be contracted. Contractors need to ensure that their individual employees are well qualified to offer the highest possible service in regards to environmental safety. Lastly but not the least is the need to have a regular evaluation process in place for all contractors to be evaluated on

The Role of the Internal Change Agent Essay Example | Topics and Well Written Essays - 2500 words

The Role of the Internal Change Agent - Essay Example From this paper it is clear that  Internal Change Agents are of three different types. The People-Change-Technology type focus on the individual employee, their morale and motivation. They deal with absenteeism, turnover, and the quality of work performed. These change agents use the techniques of job enrichment, goal setting, and behaviour modification. They work on the assumption that â€Å"if individuals change their behaviour, the organisation will also change†.This study outlines that  the Organisation-Development type are change agents who are involved in internal processes such as intergroup relations, communication, and decision making. Their intervention technique is referred to as the cultural change approach, because they analyse the culture of the targeted organisation. This approach was developed from the domains of sensitivity training, team building, and survey feedback. While implementing organisational change processes, managers often assume the roles of t he different types of internal change agents outlined above. The internal change agent as Researcher is closely related to the previous role of trainer. The role includes the training of organisation members in the skills required for valid evaluation of the efficacy of action plans that have been carried out. Lunenburg states that as part of the overall intervention strategy, the change agent designs an evaluation component, useful for solving both the current as well as future problems.

Collection proposal of african art object - Research Paper Example The Marshall Cavendish Corporation states that scientists have found it a mystery to explain the tools that were used to curve the construction stones transport and lift them up during construction. Moreover, the technology that is behind the joinery material for the construction work is yet to be discovered by the modern scientist. The construction of the Egyptian pyramids is a mystery that many generations are yet to uncover. Marshall Cavendish Corporation indicates that many have resorted to using various myths in explaining it, with some suggesting that their existed giants that were responsible for the lifting of construction stones.1 The ancient Egyptians had a strong reverence of the dead; they believed that the human soul and body were very special and important for the existence of humanity as well as in life and death. Mummification and burying of the dead in tombs was widely embraced in the ancient Egypt, this was solely done for assisting the dead find their route to the afterword.2 The ancient Egyptians perfected a tradition of filling the tombs with treasures such of gold, silver and other precious stones, tools, food, and domestic wares. This was aimed at ensuring that the deceased lived a happy life when his or her soul returned to life in the underworld. In other words, the ancient Egyptians believed in life after death, thus the need to prepare for it. The deceased was buried with all necessities for life as a way of guaranteeing the him or her better beginning to the life after death.3 This explains why treasures have been repeatedly discovered in the ancient tombs in Egypt. The pyramids were also used as tombs, mainly for the royal families. Tombs were prepared early; they were not to be constructed upon an individual’s death as it is in the modern days. The after death life was perceived to be very important, thus the need

Business goverance Essay Example | Topics and Well Written Essays - 1250 words - 1

Business goverance - Essay Example The BLM wants to charge the DBD $3 million in case the DBD does not reclaim the land when it has done drilling. In this case, a problem between the two arises. In understanding the situation at hand, we must look carefully at what a principal – agent problem is. The principal – agent problem occurs when a situation arises that motivates an agent to represent the principal in dealing with a particular situation. The BLM may be unable to meet the cost of drilling or may be too involve to drill the oil (Winch 2010, 28). This makes them delegate the whole drilling to another company. DBD, on the other hand, may be specialized in the drilling of oil and they may be the best person who can drill this. In leasing the land by BLM to DBD the company stands to gain more than it can lose as the cost of drilling and maintenance will be passed on to DBD. Nevertheless, a problem arises where they are not sure whether DBD will reclaim the land after it is done with drilling or not. It, therefore, wants to charge DBD $3 million as money for reclaiming the land which if they do not they will spend $3 million to do it whereas DBD will spend $2 million for the reclamation of the land. The total cost of leasing the land to DBD is $5 million so they are afraid if they do not charge the $3 million, they would only make a profit of $2 million shillings. This is a business and its principle objective is to make maximum profits. In principal – agent delegation many advantages are drawn. These include improved decision-making and the efficiency of these decisions. Decisions are wholly passed to the agent who takes the problems as their own and works to towards finding viable decisions. This means that the principal only wants a particular payoff but the rest is left to the agent. In the example of BLM and DBD, the BLM can be likened to a Landlord and the DBD as a tenant. The property owner will lease the land to the tenant and pass all that concerns to it to the tenant

Only Christian believers can or should be theologians Essay Example for Free

Only Christian believers can or should be theologians Essay Using quotations from at least three written texts (ancient and/or modern), argue the case for or against the view that only Christian believers can or should be theologians Before attempting to answer this question, one must define some principles of the nature of Christian theology. It is obvious that anyone may create a theology based purely on ideas from ones own imagination, with no boundaries or guidelines to it. Such a theology may be creative, intelligent, and reasonable, but could not be classed as Christian theology. Something must act as a rule and a guard, lest the Christian religion break down into nothing more than dispersed, individual, self-made theologies. Theology in a Christian context must and does find its foundation in Scripture, the supreme authority to life and thought (Vanhoozer 1998, p. 380). Now that the thing that is to be interpreted in the building of Christian theology has been identified as Scripture, one may ask the question of who is able and qualified to interpret it. In 1860, Benjamin Jowett published his essay, On the Interpretation of Scripture. He argued that the Bible should be regarded as any other ancient collections of literature, using tools of literary and historical scholarship. He implied that a critic who stands apart from traditional beliefs and practices is in a better position to find the true meaning of the text, as these traditions had obscured their true meaning. In other words, only those with the right scholarly tools and who were willing to suspend any belief in the text that they may have are able to correctly interpret it (Vanhoozer 1998, pp. 378-379). However, Jowetts view of interpretation omits the spiritual and the ethical dimensions of Biblical interpretation. Vanhoozer writes: To call the Bible Scripture does not make its warnings or its promises something other than warnings or promises, but rather reorients them to the larger purpose of making wise unto salvation . (Vanhoozer 1998, p. 380). Jowetts approach to interpretation requires an objective reading of the text. But can one properly interpret the Scriptures from such a standpoint? To answer this, one must examine the relationship between the reader, the text, the author, and the story. Upon reading, the reader reads the text, and in doing so reconstructs the author in his own imagination, creating an implied author, and bringing the story to life (actualising the text) from the marks on the written page (Voelz 1995, 1997, pp. 218- 219). Voelz goes on to state that the intended recipient of the text is: a reader of whom the author is conscious, one who may also be called implied. And this implied reader stands in the same relationship to the actual reader as the implied author stands to the actual author; he is, again, a construct, not in the real world, and he is detectable (only) in the text. Who then is a valid interpreter of a text? It is he who conforms to the expectations of the author. It is he who conforms himself to the given texts assumptions. It is he who becomes the implied reader and only such a one of a given text. Which means that an objective reading of a text is not only impossible; it is not to be desired! (Voelz 1995, 1997, p. 219) One can see that what is needed for correct interpretation of Scripture, is a subjective, rather than objective reading of the text. Voelz argues a reader interprets within a community, having developed the beliefs and attitudes of the implied reader, through discussion, experience, and training within that community which understands and appreciates the context of the implied reader. Therefore: A valid interpreter of a text is that person who assumes the role required as it were, by a given text who becomes the reader implied or called for by that very text. And such a one is formed to assume that role by a community, a community which has assumed that role itself. (Voelz 1995, 1997, p. 220) This, however, does not make every Christian communitys interpretation infallible, because humans err; thus different Christian communities often disagree on the interpretation of certain parts of Scripture. But, as the Church is a community within which these documents were produced, received, and preserved, Vanhoozer states: [The] Bible is more likely to be misunderstood by an unbelieving and unaffiliated individual than by a believing and practising member of the church. (Vanhoozer 1998, p. 378) In the case of the New Testament, the books were produced, received, and preserved by the Christian community, and following Voelzs argument, one has to be within a Christian community, and taught to read Scripture by that community, to be able to correctly interpret the New Testament. The issue of the interpretation of the Old Testament is one that is referred to in the New Testament. Speaking of the reading of Scripture by the Jews: Yes, to this day, whenever Moses is read a veil lies over their hearts. But when one turns to the Lord, the veil is removed. (2 Cor. 3:15-16 ESV) According to Pauls argument, the Jews do not believe, therefore they cannot, in their unbelieving state, be the implied reader of the Old Testament Scriptures. Apparently, simply being within the Jewish community is insufficient to correctly interpret these Scriptures, as more than a simple, straightforward understanding of the Hebrew text is needed. Luke 24:45 ESV reads, concerning Jesus and his disciples, Then he opened their minds to understand the Scriptures. Minds must be opened, veils taken away. The Christian community must teach readers to interpret even the Old Testament books. Only within the Christian community can ones mind be changed in the proper way (Voelz 1995, 1997, p. 226). The reason for this is clear from the New Testaments claims regarding the Christocentricity of all Scripture, Old and New Testaments: You search the Scriptures because you think that in them you have eternal life; and it is they that bear witness about me (Jn. 5:39 ESV. Cf. Mt. 2:4-6, 14-15; 1 Cor. 10:11, 15:3-4; 2 Cor. 1:20; Heb. 9:11-12; 1 Pet. 1:10-12) In order to be within the Christian community, one must adhere to and confess its creeds. Voelz writes: Therefore, to adhere to the creeds gives one an orientation to the books of the NT. which is congenial to them and which allows/enables one to interpret them in accordance with their intention [Adherence] to the creeds enables one to matrix the signifiers and meanings of a text for interpretation and then to interpret that matrix in a way which is congenial to the text, for the creeds are of one piece with that text and provide, as it were, the interpretive key,determinative for the meaning of the complex signifiers under construction [The] creeds help to determine which readings of Scripture are the apostolic/Christian readings which may legitimately be drawn from them. (Voelz 1995, 1997, p. 222) It was precisely the misuse of Scripture by heretics, which caused the early Church father, Tertullian, to write regarding them: [We] oppose to them this step above all others, of not admitting them to any discussion of the Scriptures. If in these lie their resources, before they can use them, it ought to be clearly seen to whom belongs the possession of the Scriptures, that none may be admitted to the use thereof who has no title at all to the privilege. (Roberts Donaldson 1994, 1995, Vol. 1 p.250 -Chapter XV of On Prescription Against Heretics. See also: chapters XVI, XVII, XVIII, XIX pp. 250-252) Tertullians belief was that the Scriptures were the property of the Christian Church alone, and not to be handled by those outside of it. Irenaeus, Bishop of Lyons, against the Valentinians, wrote: [They] endeavour to adapt with an air of probability to their own peculiar assertions the parables of the Lord, the sayings of the prophets, and the words of the apostles, in order that their scheme may not seem altogether without support. In doing so, however, they disregard the order and the connection of the Scriptures, and so far as in them lies, dismember and destroy the truth. By transferring passages, and dressing them up anew, and making one thing out of another, they succeed in deluding many through their wicked art in adapting the oracles of the Lord to their opinions. (Roberts Donaldson 1994, 1995, Vol. 3. p. 326 -Chapter VIII of Against Heresies) In conclusion, there seem to be many problems opposing the idea of those outside of the Christian Church being theologians, not least the question of motive, as the early Church fathers addressed. For these reasons, I believe that theology is a matter only for those within the Church. Bibliography * Roberts, A. Donaldson J.

Structure of an Organization Essay Example for Free

Structure of an Organization Essay Organization structure refers to the method which the organization utilizes to distribute its workers and jobs across the organization so that the tasks of the organization can be performed and the goals of the organization be achieved. Therefore, there exists a number of such structures e.g. divisional, multidivisional, matrix or functional structure. This paper evaluates the usefulness of functional and multidivisional structures. Gareth Jones (2007) defined the organizational structure as the total number of ways whereby the workforce of the organization is distributed into different tasks and their coordination then is realized among such tasks. Adner Levinthal (2001) observed that the way in which organization structure evolves is as a result of the shift in competition from innovation in product to innovation in process. This change, as the market for the products or service of the firm grows, causes the structure of the firm to grow as well and may therefore turn from functional to multidivisional. Utterback Abernathy (1975) observed that after an organization is formed it compete with other organizations in the market on the basis of its differentiation strategy. They start off on the basis of product differentiation and as they grow further, they change their focus from product alone to cost differentiation strategy as well as economies of scale. This leads them to invest more in the manufacturing process and other processes to make their product stand out as a specialized one. Tushman Anderson (1986) observed that this process may not be uniform every time. Some technological or technical discontinuity might cause this process to halt and thus start it all over again. They further observed that some companies may also focus on process innovation to stand out against competitors e.g. Toyota. However, other companies might like to continue on the basis of differentiation strategy e.g. BMW. Therefore, the lifecycle model represents a significant framework for organizations to devise their strategies and the processes they need to focus on in various competitive environments (Oster, 1994; Porter, 1980) Utterback Abernathy (1975) also defined the ways whereby the evolution process of the organization shapes up  the strategies of the firms. Gort Klepper (1982) gave effect to lifecycle model of industries by employing microeconomics supply side rationales as well as evolutionary economics. They nevertheless derived the same results. They too observed that organizations evolved first on the basis of product differentiation and on the basis of functional model and gradually shifted towards the increase in the number of firms under their auspices. When they reach at the peak they have a number of firms under their umbrella which require for a more in-depth management causing them to shift towards divisional management. This stage is called the maturity stage of the organization. This is the stage when the firm is stable from low level to the top (Utterback Suarez, 1993). Lifecycle theories all agree that organizations start on the basis of competitive strategies and as they evolve their structure experiences change. The early stage of any organization witnesses product innovation. The organizations usually focus on bringing innovation in a product that they launch in the market to distinguish it from the rest. The product is designed as per the latest needs of the consumer but existing needs are also satisfied by the product. Utterback Abernathy, 1975 They then gave the examples of the product innovation in market by organizations i.e. the new products which were launched in market to compete with existing products on the basis of innovation and meeting the latest needs of the consumers e.g. AC systems were introduced to compete with DC systems and internal combustion engines were introduced to c ompete with steam engines. Utterback Abernathy (1978) observed that in the initial stages when the product is being launched by the new organization, that organization is usually of small structure and the aim of such organization is to respond in a fast paced manner to the demands of the customers. However, when the firms get to the stage of maturity, they focus on the improvement of the process along with that of the product. They then involve the employment of latest technology and produce a dominant product e.g. AC systems came up as a dominant product compared to DC systems and internal combustion engines came up as dominant products as compared to steam engines. This transition from product innovation to innovation in process along with the product causes most of the organizations to change their structures so that new capabilities can be acquired by them. Talha (2005) described functional structure of the  organization as the one which involves the people being grouped together in a tight group to pe rform same activities or utilize same technologies and in the same department. This is therefore usually the structure of smaller organizations. This structure has its own weaknesses and strengths. Jones (2007) observed that functional structure represents that design of the organizational structure whereby the people involved possess common expertise, skills and resources. The aim of organizations structured in this manner is to enhance their effectiveness so that their goals can be achieved by them. Jones (2007) said that the main advantage of this type of structure is that people work closely together so they work in a team like manner and have the opportunity to learn from each other. They tend to be more specialized over time as well as productive. Since they possess same expertise and skills therefore they can also supervise each other conveniently. This enhances the effectiveness of the organization. Brews (2004) observed that functional structures first started to appear in 20th century when the industrial age started to emerge. The main concern for the management in that age was the efficiency of the organizations. The functional structure involved few managers which were at top while at bottom there were people. These people were organized as per the activity they used to perform. Authority was descended onto from top to bottom. However, despite the advantages enunciated above, there were also problems related to the functional structure. These were mostly two fold i.e. they involved communication and control problems. With the growth of the organizations and with the growth in its units and people, it became difficult to communicate since people and units became distant from each other in the same organization and it became difficult to measure the capability of the groups with few managers. It also gave rise to location problem i.e. it became difficult to locate every unit at one place while on the other hand if they were located at different locations it again gave rise to communication problems. (Jones, 2007) The control problem related to the management of wider number of people and units within the organization. It became difficult to control a large number of people possessing different skills as per the needs of the organization by same little number of managers. It also became difficult to gauge the problems and demands of the customers as the organizations grew as managers were busy in finding ways to coordinate with  widespread units/people while having little time to pay heed to customer queries, etc. Therefore, as organizations grew they started to get divided in various divisions with each division having its own management system. Each division then could have its own functional management system. This is what is referred to as multidivisional structure. (Jones, 2007) Such multidivisional structures arose due to different types of people working in the same organization, having had the need to establish different units in the organization to meet customer demand s and develop innovative products, increased integration and increased vertical differentiation. In such instances organizations usually gave effect to multi divisional structure to meet the management needs of the organization. The focus of the multi divisional structure is to create small divisions within the organization with each division having its own management. Robbins (2009) observed that in multi divisional structures, each unit of the organization usually has its own management which is structured on a functional pattern. He believed that multidivisional structure is viable for those organizations whereby the same product requires different parts to be assembled to form one product and that such product is sold in various markets. Jones (2007) said that at the heart of the multi divisional structure is the corporate headquarter which is entrusted with overseeing the managers of each division of the organization. A number of Fortune 500 companies e.g. Nestle, General Motors, Pepsi Co and Coca Cola have multi divisional structures. Dessler (2004) observed that the main feature of the multi divisional structure is that the organization is â€Å"departmentalized†. He said when an organization grows successfully and a number of other brands also comes under its auspices e.g. as there are a number of brands acquired by Coca Cola over time, then it has to maintain different units for different purposes. For example, the unit entrusted with the responsibility to find marketing channels in USA may lack the competency to find marketing channels in Europe or China in which instance it would be a separate unit having such responsibilities. Each region would thus have its own unit but of the same organization and each unit may have its own management structure as well. Ireland (et al. 2011) observed that functional structure is relevant and appropriate for smaller organizations and for those organizations which have just begun their operations. They gave example of Wal-Mart Stores Inc. that the store started  off with functional structure in the beginning and progressed further. Moreover, Ireland (et al. 2011) also argued that one cannot apply the same structure to each organization. It is the circumstances of each company and organization which dictate the need for the relevant structure. Thus, organizational structure represents the fashion in which organization organizes itself from top to bottom. It may be functional in the starting when the organization has just begun its operation while it may be multidivisional when the organization is huge in terms of its operations, products and services such as Fortune 500 companies.

The Pulfrich phenomenon

The Pulfrich phenomenon Introduction What is the Pulfrich Phenomenon? The Pulfrich Phenomenon is a three dimensional illusion where a moving object is seen to move in an anomalous pathway when viewed binocularly with a light attenuating filter placed in front of one eye. This creates the illusion that an object oscillating on a frontal plane appears to follow an elliptical pathway. The most widely accepted theory for this illusion is that reducing the brightness of a stimulus to the retina of one eye causes relatively slower excitation of the photoreceptors (www.suic.edu) and therefore a delayed processing of the image relative to the other eye. (1) This creates a latency difference between the two eyes and as a result, information for two different scenes from each retina arrives at the visual cortex at the same time. Information from one eye will arrive at the cortex milliseconds later than the other. A geometric disparity is registered cortically from the input of the two eyes (7) and this leads to the incorrect perception of the movement and relati ve positions of objects observed by the individual. Many ocular or neurological disorders that affect the visual pathway can produce a delay in signal transmission to the brain, creating a geometric disparity. The illusions created by this geometric disparity produce troublesome symptoms for individuals with a condition and is why many patients experience problems in everyday life as a result of the phenomenon.(5) Who first discovered the Phenomenon? Carl Pulfrich, a physicist with the Zeiss Company, described the phenomenon in 1922. He was not able to observe the effect himself however due to a childhood injury, which left him blind in one eye by 1905. The phenomenon was first noted earlier however by astronomers using stereo-comparators to search for planets.(3) Demonstrating the phenomenon The Pulfrich phenomenon can be observed in a normal individual by binocularly viewing a swinging pendulum bob whilst holding a neutral density filter in front of one eye. The pendulum bob or target used to elicit the phenomenon may take the form of a mechanical or computerized target. The neutral density filter lowers the retinal illumination of the eye it covers, and this creates the difference in signal transmission time between the two eyes. This delay created by a reduction in retinal illumination is supported by several psychophysical and electro-physical investigations.(1)((8,9)) The geometric disparity created by the visual latency difference between the eyes is interpreted by the brain as depth by the binocular disparity detectors.(2) This is why the pendulum bob is perceived to oscillate in an elliptical motion instead of moving along a frontal plane. The perceived direction of the pendulums swing is dependent on which eye the filter is covering; the pendulum appears to rota te clockwise when the filter is placed in front of the left eye and anti-clockwise when it is in front of the right eye. Provoked and Spontaneous Pulfrich Phenomenons When the Pulfrich phenomenon is induced in a normal individual i.e. using neutral density filters, the phenomenon is sometimes called the provoked Pulfrich effect. Since a delay can occur in individuals with ocular or neurological disorders that affect the visual pathway, the Pulfrich effect can occur spontaneously. Such diseases which may result in a spontaneous Pulfrich effect include optic neuritis, an inflammation of the optic nerve which can cause swelling and destruction of the myelin sheath covering the optic nerve. Since this myelin sheath helps conduct nerve impulses along its axons faster than non-myelinated axons, its destruction will lead to a slower transmission to the occipital cortex, where the information is processed. Optic neuropathies with bilaterally asymmetrical demyelination are thought to be the most common causes of the Pulfrich Phenomenon and the visual symptoms it is associated with. (website) Systemic conditions such as Multiple Sclerosis, a demyelinating d isease were the fatty myelin sheaths around axons are damaged (Miller DH, Leary SM (October 2007). Primary-progressive multiple sclerosis), can lead to many individuals experiencing the Pulfrich Phenomenon. The Pulfrich Phenomenon has also been reported in many other diseases such as unilateral cataract or asymmetrical bilateral cataract. A cataract may reduce retinal illumination or produce retinal blur thus leading to a visual latency in the visual pathway of the affected eye causing the phenomenon in the individual. Anisometropic amblyopia, strabismus, corneal opacity, anisocoria, unilateral mydriasis, Central serous retinopathy, and age-related macular degeneration have all been accountable to produce the Pulfrich effect to some extent in an individual. Retinal blur has also been thought to be cause of the effect, most noticeable in smaller targets. Sokol and Moskowitz (cat(13)) showed that a 12 ms increase in the visual latency resulted from a 3 dioptre refractive error.() A spontaneous Pulfrich phenomenon is not uncommon and has been found quite frequently in studies with patients with ocular and neurological disorders. It was found in 24 out of 93 patients with recovered optic neuritis, 16 out of 29 patients with uncomplicated unilateral cataract and three out of 70 patients with various strabismus problems.(3) Factors affecting the magnitude of the Phenomenon seen The magnitude of the Pulfrich Phenomenon seen depends on a number of factors with retinal illumination being one of the most significant. The magnitude of Pulfrich effect seen i.e. the depth of the elliptical trajectory, is larger for increasing disparity of retinal illumination between the two eyes. This may occur in a patient with a spontaneous Pulfrich phenomenon, for example when one eye has a much denser cataract than the fellow eye. It may also occur in cases of uniocular mydriasis when anisocoria could be induced. (2) The eye with the larger pupil receives increased retinal illumination than the other eye with a smaller pupil and therefore the phenomenon may be induced. This may also occur when the Pulfrich phenomenon is provoked, i.e. when a neutral density filter covering the eye is increased in depth. Lit ((2)12) has shown that the magnitude of the Pulfrich effect seen, that is the size of the ellipse, is proportional to the density of the filter used. The distance from which a pendulum or similar target is viewed, also has an effect on the magnitude of the Pulfrich phenomenon seen. An increase in the magnitude of the phenomenon can be observed as the distance between the observer and target increases. Target velocity also contributes to the magnitude of the Pulfrich phenomenon. As the target velocity increases, so does the magnitude of the Pulfrich effect seen by the observer, leading to much more noticeable illusions and increased visual symptoms. Symptoms experienced due to the Phenomenon The symptoms expressed by a patient with the Pulfrich phenomenon to a general practitioner or optometrist can be quite strange. Objects appear to move in incorrect pathways when either the observer or the target is in motion.(3) Objects moving up and down however will not demonstrate this effect or lead to symptoms as a result of misjudged distances. These symptoms experienced lead to difficulties in everyday tasks. Tasks such as driving and various ball game activities like football, which require good perception of moving objects, have been found to be more difficult for patients who have the Pulfrich phenomenon. Even the simplest of tasks such as navigating through doorways or pouring a drink have been found to produce an increased level of difficulty for such patients. Several studies have revealed that visual impairment leads to increased car accidents and difficulty driving. Visual perception has a key role in the safe operation of a vehicle, helping prevent driving errors and therefore prevent accidents and fatalities. In order to drive safely, a driver must be able to act and react to the changing environment around him/her. This requires the ability to correctly estimate the relative positions of moving and non-moving objects. Some Patients with a spontaneous Pulfrich phenomenon have complained of oncoming cars apparently swerving across the road towards them. This visual perception could lead to a serious accident and therefore must be treated to help prevent any casualties. Individuals who were later diagnosed with pathologies thought to be the cause of a spontaneous Pulfrich Phenomenon have reported the illusion that whilst driving, oncoming cars appear to swerve across the road towards them. Perception of this would lead to the driver maki ng a sharp turn away to escape what he/she thinks is a certain accident. Forty years ago, a traffic accident was reported which occurred as a result of an induced Pulfrich phenomenon due to unilateral pupillary dilation. (reference) Since then, many investigations have been carried out to learn more about the effect a spontaneous Pulfrich phenomenon has on driving. It was found that many individuals had problems with judging distances when driving, especially when performing manoeuvres such as reverse parking into a garage.(references) Why is it useful for optometrists to be able to diagnose and treat the Pulfrich phenomenon? Due to troublesome visual symptoms experienced by patients known to have the phenomenon, it is in the interest of both the patient and Optometrist that the Pulfrich effect is diagnosed and treated as soon as possible. Various studies have shown that unilateral mydriasis was found to always produce the phenomenon on subjects.(reference) Because of this, it would be important for the Optometrist to warn the patient in advance of dilation, the visual symptoms and difficulty judging distance that can be expected, and also to warn, if possible, the patient should not drive home. It has also been suggested that, because patients with conditions such as cataract and optic neuropathy often demonstrate the Pulfrich phenomenon, an effective test for the Pulfrich phenomenon might be a useful addition to the tests available to Optometrists in primary care practice. The detection of this phenomenon may aid prompt diagnosis of any underlying pathology therefore the correct management and treatment could be initiated without delay. Recognition of this phenomenon could be particularly helpful in the early diagnosis of Retrobulbar neuritis, the most common form of optic neuritis in adults and frequently associated with multiple sclerosis (Jack J Kanski). In retrobulbar neuritis, the optic disc appearance is normal, at least initially, because the optic nerve head is not involved and so early detection is difficult using direct or indirect Ophthalmoscopy. Testing for the Pulfrich phenomenon is the only way to clinically determine if motion stereopsis is normal or not. Visual Evoked Potentials are not useful in analysing how motion stereopsis is affected, as their signals are travel via different visual pathways. VEPs are also not available to primary care optometrists. Standard stereo-tests such as the Frisby stereotest commonly used in Optometric Practice also fail to detect any abnormalities in motion stereopsis. (1) Knowledge and understanding of the Pulfrich would help the O ptometrist appreciate many of the strange symptoms experienced by an individual with the Pulfrich phenomenon and the many kinds of problems faced in daily life by i.e. sports games and traffic situations. The symptoms experienced by a patient with the phenomenon can be quite easily ignored or dismissed if the clinician is unaware of the phenomenon. If optometrists had the appropriate equipment and knowledge to diagnose the Pulfrich phenomenon in everyday practice, they would also be able to treat the phenomenon and its sometimes-disabling effects using simple filtered lenses. This would help reduce or eliminate any of the problems experienced as a result. Patients, that find even the simplest of tasks such as pouring a drink or navigating through doorways, may be enabled to carry out these tasks with ease after treatment. Management and treatment of the phenomenon may also allow patients who retired from driving a vehicle due to the visual difficulties faced with the Pulfrich effect to feel confident in driving again. The unusual symptoms experienced when driving due to the Pulfrich phenomenon, especially the location of moving objects encountered in traffic, could be eliminated with the simple treatment available. How is the Pulfrich phenomenon treated? The symptoms experienced by patients with a spontaneous Pulfrich phenomenon can be reduced or eliminated by placing an appropriate neutral density filter or optic tint in front of the unaffected eye. (3) The lens has the effect of reducing retinal illumination of the unaffected eye and therefore creates a delay in signal transmission to the visual cortex, which equals the delay in the affected eye. To choosing a correct filter, the patient is shown a range of filters of varying densities and asked to decide which lens alleviates their symptoms and removes phenomenon. Once the suitable lens filter has been chosen, it may then be worn as spectacles or as a contact lens. Optic tints are preferred to neutral density filters as they are more readily available and cost effective for the patient.(3)The filters used to treat the phenomenon should remain the same without needing to be updated, so long as the underlying pathology remains stationary.() Other Diagnostic methods Doctors and other Healthcare professionals have found many different ways of testing for the phenomenon. The most often suggested method is to swing a pendulum in 5 different pathways in front of a patient. A pendulum is swung in each of the pathways, from A-E. If the right eye is affected, the pathways C and B produce the most marked effect for the patient. The pendulum appears to veer towards the patient as it gets closer on these pathways. Picture from Charles J. M Diaper, 1997 Surv Ophthalmol Another technique used by some medical professionals in detecting the Pulfrich Phenomenon is when the examiner instructs the patient to quickly walk past the examiner whilst trying to brush his/her shoulder on either side. If the effect is present the patients left eye for example as shown in the diagram below, usually the affected eyes side will result in a large gap between the patient and the examiner. Errors in spatial localization result in the misjudgement of the distance between the patient and examiner. The patient can be seen to make a course correction, which can be seen as a rapid lurch away from the examiner. (6) The incorrect distance judgement by the patient is a result of an illusion caused by the Pulfrich phenomenon leading the patient to believe the examiner is closer than what he/she actually is.(3) Note that this gap would only occur on the same side of the affected eye. For example if the patients right eye were affected on the picture left, a large gap would not be observed. What my project is about? In this project we are interested in investigating which tests prove most effective to an Optometrist in detecting the Pulfrich Phenomenon and also what the optimal parameters are for eliciting the Pulfrich effect in visually normal observers. With the ready availability of computerised stimuli for eliciting the Pulfrich effect, this may now be possible in practice. We would like to investigate which of the currently available online versions of the Pulfrich phenomenon stimuli are most successful and sensitive at eliciting the Pulfrich effect. I will also test a range of neutral density filters of varying depths to see which induces the phenomenon best in a group of visually normal adults aged 18-30. I will also be recording the distances at which the subjects were placed in relation to the screen throughout the test to see what effect this may have on detecting the phenomenon on how sensitive the different stimuli were at detecting the Pulfrich phenomenon in the subjects.

Chinua Achebes Things Fall Apart Essay -- Author Literary Analysis

As a man of great wisdom, knowledge, tradition, and culture, Chinua Achebe is a promoter of education and tradition who is well versed in both his African roots and Christian religion (Loveday). He has won awards like the Man Booker and Commonwealth Poetry Prize for his novels, short stories, essays, and children’s books and was thrust into fame after publishing Things Fall Apart. Born Albert Chinualumogu Achebe, in colonial Ogidi, Nigeria, he is the son of missionary teachers Isaiah and Janet Achebe. He was born on November 15, 1930 to a devout Anglican family; however, his parents still allowed Achebe to experience his tribal tradition as well (Telgen 262). He left Ogidi to go to school at Government College, and from there he went to the University College of Ibadan where he studied English, theology, and history. There, he earned his BA and departed from his British name to embrace the name Chinua. From 1953 to 1966 he was a writer for a Nigerian broadcasting company. Soo n after, he became a diplomat for the Biafran government during Nigeria’s Civil War. Eventually Achebe became a professor at the Universities of Nigeria, Nsukka; Massachusetts, Amherst; and Connecticut. In more recent years, he unfortunately became a paraplegic in a car accident in 1990 and was exiled from Nigeria until 1999. He currently teaches at Bard College in New York, yet he still directs an educational book company and a bilingual magazine in Nigeria. Achebe’s work comments on the changing political and social conditions of Africa and especially on the change that colonialism brought to his home country. He is noted for keeping his ideas fair and understanding, unlike others, for he learned both English and African points of view (Petri and Pesonen)... ...graphies. 6th ed. EBSCOHost, 1 Dec. 2009.

Charles Lindbergh :: History

Charles Lindbergh Charles Lindbergh was born on February 4, 1902, in his grandfather's house in Detroit. The son of a lawyer and U.S. congressman, he grew up on a small farm in Minnesota (Lindbergh Biography, ONL). As a child, Lindbergh showed remarkable mechanical ability. He could understand every part of his motorcycle and car as he grew older. After graduating high school, Lindbergh worked on the family farm for two years before enrolling in the University of Wisconsin-Madison to study Engineering (Charles Lindbergh biography, ONL). But, after two years, Lindbergh found something else that excited him. He was more interested in the expanding field of aviation (Lindbergh Biography, ONL). He left college to attend the Lincoln Flight School in Nebraska. Once graduated, he spent the next few years performing daredevil stunts at county fairs and carnivals as a barnstormer (Charles Lindbergh biography, ONL). In 1924, on advice from his father, Lindbergh enlisted in the United States Army to be trained as an Army Service Reserve pilot. A year later, he graduated first in his class and was hired by the Robertson Aircraft Corporation of St. Louis as an airmail pilot. Gaining a reputation for being a cautious and capable pilot, he flew the mail between St. Louis and Chicago (Lindbergh Biography, ONL). During the course of his job, Lindbergh heard of the famed Orteig Prize. In 1919, Raymond Orteig, the owner of Brevoort and Lafayette hotels in New York City, made an offer to "flying buffs". Orteig offered a prize of $25,000 to the first aviator to fly nonstop from Paris to New York or New York to Paris. Before 1926, no one had even attempted the feat. But, as aviation technology developed, the challenge began appearing possible (Spirit of St. Louis, ONL). Before becoming an airmail pilot, Lindbergh hadn't even heard of the Orteig Prize, but he immediately became interested (Lindbergh Biography, ONL). In 1927, Lindbergh obtained a financial backing of $15,000 from a group of St. Louis businessmen, and he set out to find a plane. Hearing of Lindbergh's search for a plane, the Ryan Airlines Corporation in California offered to build him a plane for $6000 (Lindbergh Biography, ONL). Working with chief engineer and designer Donald Hall of Ryan Airlines, Lindbergh designed "The Spirit of St. Louis". Lindbergh and Hall designed the airplane specifically for "getting to Paris". In order to cut down on weight, any item considered to heavy or unnecessary was left out including a radio, parachute, gas gauges, and navigation lights.

A PSO Based Cluster Formation Algorithm for Optimal PMU Placement in KPTC

A PSO Based Cluster Formation Algorithm for Optimal PMU Placement in KPTCL First A. Writer,Appellation, Organization, Second B. Author, and Third C. Author, Jr. , Designation, Organization Abstraction— Power system province appraisal with the sole deployment of synchronal phasor measurings demands that the system must be wholly discernible with PMUs merely. Direct measuring of stage angles of current and electromotive force phasors are now possible by Phasor Measurement Units ( PMUs ) . To hold lesser figure of PMUs, the arrangement job in any web is considered as an optimisation job. This paper presents a Particle Swarm Optimization ( PSO ) based bunch formation algorithm for optimum PMU arrangement. The proposed algorithm clusters the coachs into many sub groups and the maximal connectivity coach is selected as the heading coach. The PMU is placed on the heading coach to pull off the affiliated coachs for complete system observability. This paper analyses the proposed algorithm for the undermentioned three instances: 1. Without PMU loss, 2. With individual PMU loss, and 3. Zero Injection Bus. The simulation consequences for IEEE coach and the KPTCL coach syste ms are presented and compared with the bing attacks. The proposed consequences show that the method is simple to implement and supply the accurate PMU arrangement.

IntroductionPower public-service corporations are confronting legion menaces of security of operation due to the over stressed power web in the today’s competitory power market scenario. Phasor Measurement Unit ( PMU ) is an measuring device which is used to mensurate the current and electromotive force. It uses the Global Positioning System ( GPS ) pulsation to ease the synchronised measurings of existent clip phasors of currents and electromotive force. A power system is said to be recognizable when electromotive force phasors at all the coachs are known. Harmonizing to Ohm’s Law, if a PMU is placed at the coach, so the neighboring coachs besides become discernible. Obviously, when PMUs are placed at all the coachs of the web, and the measurings fo r all the PMUs are communicated to the control units, so the electromotive force phasors at all the coachs would be known. This attack can alter the traditional appraisal to province measuring. PMUs are already installed in several public-service corporations for assorted applications around the universe such as province appraisal, adaptative protection and system protection strategies. Other application Fieldss include stableness monitoring, Wide Area Monitoring and Control ( WAMC ) and efficient system use. In the traditional power systems, the coachs are monitored utilizing the conventional measurings from electromotive force and current transformers and the informations are forwarded to the Energy Management System ( EMS ) through the Supervisory Control and Data Acquisition ( SCADA ) system. It collects the existent clip measurings from the Remote Terminal Units ( RTUs ) placed in substations. This attacks are non able to supervise all the measurings across a broad country power system because the informations are non time-synchronized [ 1 ] . PMUs are an indispensable portion of smart grids and therefore the rate of PMU installings are increasing. In the emerging engineering, the major issue demand to be addressed is the arrangement of PMUs, which is influenced by the awaited system applications. The major factor restricting the figure of PMU installings are their cost and the communicating installations. Hence, the cost and communicating restraints of PMUs have been motivated the r esearch workers to place the minimum PMU installing for the awaited applications. Puting PMUs on all coachs of the power system consequences a complete observability of the system. Since, a coach is observed if a PMU is placed on it or some of its adjacent coachs, it is neither economical nor necessary to transport set such installings. As a effect, a job called Optimal PMU Placement ( OPP ) job has been occurs. The purpose of this paper is to place the optimum figure of PMUs to do the KPTCL topologically discernible. Here, a PSO based Clustering Algorithm is proposed to constellate the coachs. The heading coach is selected based on the maximal connectivity among the coachs. The heading coach is placed with the PMU to supervise the other affiliated coachs. The PMU arrangement scheme confirms the system observability during the normal on the job conditions and besides the individual PMU failures. The proposed method is found to be simple, fast and accurate in calculation. The proposed method is applied on IEEE-6, IEEE-7, IEEE-9, IEEE-14, IEEE-30 coach systems and KPTCL power maps for 28 coach, 127 coach and 155 coach systems to verify the proposed algorithm public presentation. The staying portion of the paper is organized as follows: Section II involves the plants related to the bing algorithms for optimum PMU arrangement job. Section III involves the description of the proposed PSO based bunch formation algorithm for optimum PMU arrangement. Section IV involves the public presentation analysis of the proposed work. The paper is concluded in Section V.II. Related PlantsWith the figure of PMUs estimated for installing in the close hereafter, both the public-service corporations and research workers are looking for the optimum solutions to their arrangement. The solutions for the optimum PMU arrangement job can be classified into two types: mathematical and heuristic algorithms. Some of the bing plants related to the optimum PMU arrangements are discussed. Integer scheduling is a mathematical scheduling attack for work outing an optimisation job holding whole number design variables.Singhintroduced an whole number programming based methodological analysis fo r the optimum arrangement of PMU.

A two phase PMU arrangement attack was proposed. Phase 1 identifies the minimal figure of PMUs to do the system topologically discernible. Phase 2 was proposed to place if the resulted PMU arrangement outputs to a full graded measuring Jacobian. A consecutive riddance algorithm was proposed to place the optimum locations of extra PMUs [ 8 ] . An Exhaustive hunt is an optimisation technique which consistently enumerates all possible campaigners for the solution. It chosen the campaigner which satisfy the restraints at the optimal nonsubjective map value. It guaranteed the determination of the planetary optimum but it was non suited for big scale systems with immense hunt infinite.Azizi et Alproposed an optimum PMU arrangement by an tantamount additive preparation for thorough hunt. The province appraisal was implemented based on the complete additive arrangement [ 9 ] . Fei et Al[ 10 ] discussed an optimum PMU arrangement based on the limited thorough attack. An about optimum PMU arrangement ( AOPP ) was established in order to place the seeking infinite. AOPP was deterministically retrieved by elaborate power system province observability analysis.

The heuristic algorithms applied for optimum arrangements are Familial algorithm, Tabu Search, Simulated Annealing, Differential Evolution, Particle Swarm Optimization ( PSO ) , Immune Algorithm, Iterated Local Search ( ILS ) , Crossing Tree Search ( STS ) , Greedy Algorithm, Recursive Security N Algorithm, Decision Tree and Practical Heuristic Algorithm.Hajian et Alintroduced an optimum PMUs arrangement to keep the web observability utilizing a modified BPSO algorithm. An optimum measuring set was estimated to obtain the full web observability during normal conditions. After any PMU loss or individua l transmittal line outage, the derived strategy in normal status was modified. Observability analysis was carried out based on topological observability regulations. A new regulation was added to minimise the figure of PMUs for complete system observability. A modified BPSO algorithm was used as an optimisation tool to acquire the minimum figure of PMUs and their corresponding locations [ 11 ] . Sharma and Tyagidesigned an optimum PMU arrangement attack based on Binary Particle Swarm Optimization ( BPSO ) with the conventional measurings. Quadratic scheduling was used in BPSO algorithm.

It was tested on IEEE-7, IEEE-14, IEEE-30 and IEEE-57 coach system utilizing BPSO technique [ 12 ] .Peng et Alformulated a multi nonsubjective optimum PMU arrangement utilizing a non-dominated sorting differential development algorithm. It is an organic integrating of Pareto non-dominated sorting operation and the differential development algorithm. It enhances the single crowding mechanism and common mechanism [ 13 ] .El-Zonkoly et Alproposed an Improved Tabu Search ( ITS ) for complete observability and out of measure anticipation. The system was based on numerical observability and unreal intelligence. ITS was used to place the optimum arrangement for the PMU to maint ain the system wholly discernible.

PSO Based Cluster Formation For Optimal PMU PlacementPower system observability is indispensable for placing the existent clip monitoring and province appraisal of the system. PMUs enable advanced solutions to bing public-service corporation jobs and supply power system engineers a whole scope of possible benefits:Accurate appraisal of the power system province can be obtained at frequent intervals,Permiting dynamic phenomena to be observed from a main location and suited control actions are taken.Post perturbation analysis will be much improved for the PMU arrangement job, which is obtained with the precise images of the system states through GPS synchronism. This subdivision proposed a PSO based Optimal PMU Placement in power systems. The aim of this method is to supply the optimum arrangement of PMUs, which can do the system discernible and to maximise the measurement redundancy of the system. Fig.1 shows the flow of the proposed method. Initially, the coach system is taken and each coach is considered as a node. Each node connectivity is updated in the binary tabular array. Here, we are sing the undermentioned three instances:Without PMU LossWith PMU LossZero InjectionsA. Particle Swarm Optimization Based Cluster Formation for Optimal PMU PlacementPSO is an optimisation algorithm which facilitates a population based search process in which single are termed as atoms. Here, the PSO algorithm is used to constellate the coachs for optimum PMU arrangement. Each atom contains a PMU arrangement constellation for a power system. It represents that each atom is constructed by binary dimensions, such that each coach of the power system has a di mension which indicates the being of a PMU in that coach, it is equal to 1, otherwise 0. Algorithm 1: PSO based Cluster Formation Input signal:Connectivity inside informations of the given coach system 1: Create binary tabular array for the given coachs as ForI = 1 to figure of coach ForJ = 1 to figure of coach Ifcoach ( I ) connect to bus ( J ) Matrix element represent as 1 Else Matrix element represent as 0 End If End For End For 2: D= Sum ( degree Fahrenheit ( x ) ) 3: L = soap ( vitamin D ) 4: Calculate the coach connexion for LThursdaycoach and topographic point PMU on that coach 5: Update the binary tabular array by extinguishing the coach from binary tabular array 6: Initialize atoms 7: Position of atoms = ‘x’ and ‘y’ organizing points of coach location. 8: Speed = random ( figure of coachs ) 9: Check fittingness for given place by utilizing nonsubjective map. 10: Minimum ( F_Position ) 11: 12: Position = Position + Velocity 13:ForK = 1 to loop IfPresent_fitness & A ; lt ; Last_fitness Update fittingness value End If Update speed and place. End For 14: Find upper limit ( fitness_value ) , mf = soap ( fittingness ) 15: Topographic point PMU on that coach. 16: Update double star tabular array by extinguishing the coach from binary tabular array. 17: Cringle to Step 6 until binary table gets empty. 18:Ifthe PMU placed at merely one coach, Check the nearest coach and made connexion between them and update bunch. 19:End If The proposed algorithm is applied on the three instances for optimum PMU arrangement.B. Case 1: Without PMU LossIn this instance, the zero injection and the flow measuring are ignored. To explicate the restraint set, the binary connectivity matric is formed whose entries are defined in the undermentioned equation: ( 1 ) The matrix can be straight calculated from the coach entree matrix by change overing the entries in the binary signifier. See the six coach system The binary tabular array B is defined as ( 2 ) The restraints for this instance is, ( 3 ) From the binary tabular array, place the maximal connectivity among the coachs. The tabular array shows the maximal connectivity is occurred in coach 3. Hence, coach 2, 3, 4, 5, and 6 are eliminated from the binary tabular array. Then, the binary tabular array can be updated as, ( 4 ) After executing the PSO based constellating algorithm, the PMU is placed on coach 1 and bus 3, which is shown in fig.3.C. Case 2: With loss of PMUIt is considered as each coach is discernible by individual PMU and these PMUs are placed by the proposed bunch algorithm. Hence, the arrangement of PMUs are extremely dependable but, if any perturbation occurred in power system or due to maintenance purpose any of the PMUs topographic points is out from the system. If any of the PMU is disconnected, so some of the coachs are connected to that PMUs are non remain discernible. In order to get the better of such unexpected PMU failures, a scheme is considered for individual PMU loss. It can be achieved if all the coachs are observed by at least two PMUs. These are operated as two sets,Primary setBackup setIf suppose the PMU from primary set is non working decently, so the backup set will take the duty to detect the coachs. To obtain the twosome of PMUs, the restraint and nonsubjective map wil l stay same by merely modifying the alteration in matrix f. In this instance, the elements of degree Fahrenheit is equal to 2 alternatively of 1. It is defined as follows: ( 5 ) This instance place the PMU for supervising the individual coach by two PMUs. Other than the nonsubjective map, the stairss are same. The new restraint map can be constructed as follows: ( 6 )D. Case 3: Zero InjectionZero injection coachs are the coachs from that no current is passed into the system. Zero injection correspond to the reassigning nodes in the system. If zero injection coachs are besides designed in the PMU arrangement job, the full figure of PMUs are farther minimized. See the undermentioned illustration for zero injection on six coach system where coach 2 is considered as the zero injection coach. Now, the restraint for zero injection coach can be written as follows, ( 7 ) From the above equation, it is identified that the coach 3 has maximum connectivity. Hence, PMU is placed on the coach for full system observability.IV. Performance AnalysisTo measure the public presentation of the proposed method, the optimum arrangement of PMU job is solved for IEEE criterion coach system and KPTCL 220 and 400 kV power systems. The KPTCL power coachs are shown in fig.6. The consequences of the proposed method for IEEE coach system is illustrated in table 2. Here, IEEE-6 coach, IEEE-7 coach, IEEE-9 coach, IEEE-14 coach, and IEEE-30 coach system are considered for rating. Table 2 provides consequences for the three instances of IEEE coach systems. We collect the information from the KPTCL 220 and 400 kilovolt power system. Here, the PMU arrangement is obtained merely for the instance 1 ( without PMU loss ) . Hence, we proposed an algorithm to obtain the PMU arrangement, which suits for all the three instances ( with loss, without loss, zero injection coach ) . Table 3 provides the entire figure of PMU arrangement collected from the KPTCL. Whereas table 4 provides the proposed consequence for the given power system. The proposed method consequences for 28 coach, 127 coach and 155 coach system in all the three instances.V. Conclusion and Future WorkIn this paper, a PSO based bunch formation algorithm is proposed to work out the optimum PMU arrangement job.

Literary Theory and Criticism, and Its Relevance Today Essay

Literary Theory and Criticism and Its Relevance Today Literary criticism is primarily the evaluation of the importance of a particular work or body of work on such grounds as: the personal and/or cultural importance of the themes and the uses of language of a text; the insights and impact of a text; and the aesthetic creation (or, performance) of the text; mainly as these areas are seen to be reciprocally dependent, supportive or inflective. The word ‘criticism’ has ordinary-use negative connotations, and to an extent that is right: for literary criticism is part of he disciplining of dialogue generally and of what is considered literature in particular. One patrols the confines of good writing, admitting or excluding, determining what should be thought about a text, and why, what personal and cultural value should be placed on it. Judgments of significance are not simple, however. They require that one consider what constitutes importance, what the personal and social importance of literature is what the significance of ‘the aesthetic’ is. And they require that one interpret the text. As texts Judged to be of high literary significance tend to be marked by complexity and even ambiguity, and to yield various interpretations, Judgment may eventually require a theory of interpretation, or at least careful consideration to the question of what constitutes, guides, and legitimates interpretation. Theory is the route of understanding what the character of literature is, what functions it has, what the relation of text is to author, to reader, to language, to society, to history. It is not Judgment but understanding of the frames of Judgment. Literary Theory is part of a prevalent movement in the culture which has affected a number of disciplines, occasioning similar disputes in some, a movement which has explored and elucidated the complexities of meaning, textuality and understanding. Literary Theory is not a single venture but a set of interrelated concepts and practices † most significantly deconstruction, post-Althusserian ideological or ‘political’ criticism, post-Lacanian psychoanalytic criticism, New Historicist or ‘cultural’ criticism, some reader-response criticism and much feminist criticism. The aim of this essay is to identify the issues that ground these contemporary literary theories. There have always been literary theories † about how literature works, what connotation is, what it is to be an author and so forth. The essential interpretive practices in force and in power in the academy which are being challenged by Theory were themselves ground-breaking, theory-based practices which became the norm. The two main crucial practices in the mid portion of the century have been the formalist tradition, or ‘New Criticism’, which sees a text as a omparatively self-enclosed meaning-production system which develops gigantic signifying power through its formal properties and through its conflicts, ambiguities and complexities, and the Arnoldian humanist tradition exemplified most clearly in the work of F. R. Leavis and his followers, which concentrates evaluatively on the capability of the author to represent moral experience concretely and engagingly. Many readers have in practice combined the principles and methodologies of these
