Theory of Gravity Essay Of all the current nuclear fusion reactor experiments JET and ITER are the largest. JET, Joint European Torus, based in Culham Science Centre in the UK, is the centre of Europes fusion research. JET is currently the worlds largest tokomak capable of delivering up to 30 MW of power, it is used by more than 20 European Countries and also used by international scientists. It is used to test the conditions that will be in use by commercial fusion power plants. JET began in 1978, in operation since 1983 and in November of 1991 became the first experiment to produce controlled nuclear fusion power. It has been a stepping stone for ITER, producing parameters that have been vital in its production. In 1997 a record of 16 MW of energy were produced by JET using the mixed deuterium-tritium fuel with an input of 24 MW; a 65% ratio. ITER, originally standing for International Thermonuclear Experimental Reactor but dropped due to negative connotations of thermonuclear especially combined with the word experimental. ITER began in 1985, but it was only until 2005 that the south of France was decided on as a location for the reactor. ITER is supported by many countries worldwide including the USA, the EU, the Russian Federation, India, China, Korea and Japan. In November 2006, and agreement was signed which formed the international ITER organisation who owns the device and all aspects of the project. ITER was formulated because it was agreed that a larger and more powerful reactor was needed to emulate conditions in a commercial reactor and demonstrate its feasibility. ITER is built from the collective research made by all the many fusion experiments worldwide; a collaborative effort to provide cheap, clean fuel for many future generations. The first plasma is predicted to be produced by 2016. Nuclear Fusion is entirely feasible as a future energy source though it will be a long time before they will overtake traditional natural resources in terms of percentage of the Earths energy provided. Estimated put it around 2050 until fusion power plants are in full commercial use. It is proven that fusion is the most efficient energy source we have to date; 4 times more than that of nuclear fission. It is inherently safe, and there is no hazardous waste except some radioactive materials from free neutrons, though in future designs this could be eradicated. Research is currently going well; all that remains is for bigger more powerful models and with ITER on the horizon it will not be long before a self sustaining fusion reaction with a positive output is achieved. This means well into the future 100% waste free fusion plants could provide nearly all of the worlds electricity, resulting in a clean safe environment with a massively reduced threat of global warming.

The Cause of the Devastation of Hurricane Katrina Essay -- Natural Dis

The historical event of Hurricane Katrina, a category three hurricane with winds ranging from 111-130 mph, in August 2005 revealed major structural failures in the levee systems of New Orleans. Though not all structural failures are as catastrophic, the breeched levees led to loss of life, homes, businesses, highways, and left a trail of destruction that is still being repaired today. The result of this failure led to lawsuits, conspiracy theories, and court cases. Hurricane Katrina had a major effect upon our country and those results are still rippling on today. Though a city once devastated, major improvements to the failed system have been made and leave the city feeling safe once again. When Hurricane Katrina hit New Orleans with its fierce intensity, the lives of its inhabitants was forever changed. The winds rose and the waves crashed upon the only security system this, below sea level, city had against the many water systems surrounding it. Most people think that the waves simply rose up over the banks and levees of the city; however, evidence proves this thought wrong. The actual reason New Orleans was flooded was due to poor engineering. According to experts, two thirds of the tragic flooding could have been prevented. Thousands of homes could have been saved if the engineers responsible for building New Orleans’s levees had followed regulatory guidelines. After the shock of Hurricane Katrina slightly diminished, the Congress ordered a congressional inspection of the federally build levee system. As they dug deeper into the cause of the levee’s failure, they began to discover flaws in the actual engineering of the levees. Three of the levees that had the most prominently negative effect on the city, and ... ...cane to protect the rich and middle class, and some blame President Bush. In conclusion, Hurricane Katrina had devastating effects on the city of New Orleans. I believe the blame was portioned correctly onto the heads of the engineers responsible for building the levees. Not enough care or attention to detail was put into the construction of the levees, and resulted in death and devastation. When it comes to the safety of people, all measures must be taken and no cost spared. This historical event learned from that, and great improvements were made to the protection system in New Orleans. Works Cited Hurricane Katrina.

Organization and Management Analysis Essay

Organizational and management analysis are an essential part of organizational environment. In the modern world, working environment characteristics are team work, delegation, information technology interfaces, which have an impact on the effectiveness of organization and management. This helps in cost reduction, decrease in environmental waste, improved employee satisfaction and an increase in overall productivity. To have an organizational and management analysis review of organizational charts, meeting with department managers, executives or board members, and an organizational survey is necessary (Jones, 2006). A multi-dimensional examination of organizational and management analysis gives a complete picture of the actual situation which can be a starting point. This paper is to describe various organizational theories, compares management theories and styles, and explains which organizational theory and management style resembles our organization. Also, this paper explains what could be changed to make our organization better. Organizational Theories Organizational theory is to identify how they solve problems and how they maximize efficiency and productivity. These theories mostly derived from the activities of successful organizations. All of these theories contributes to the overall understanding of management. As in any other theories organizational theories provide the basis for ongoing research and application of human behavior in organizational settings. Classical Organizational Theory Focus on the theories of efficiency. The components include scientific management, bureaucratic theory, and administrative theory. Scientific management focus on getting the best from the people, equipment, and business. So that productivity can be increased. In this, the workers got scientifically selected, trained and taught for the work. On the other hand, bureaucratic theory focus on establishing a hierarchy, division of labor, rules, and regulations. In the current world, many of the managers think that bureaucratic theory is a hindrance to employees’ creativity. Administrative theory establishes a set of management principles and functions that applied to the organizations. This serves as a centralized  decision making approach (Coulter & Robbins, 2012). Neoclassical Organization Theory This theory emphasizes effective and sociopsychological aspects of human behaviors in an organization. As we see in many of the current organizations many of the managers motivate, lead, build trust, work with the team, manage conflicts is all based on the organizational performance approach. The way manager design jobs, work with the employees, the method of communication is general in the behavioral approach. Productivity increases in an environment with coherence of values and purpose. The key is to maintain equilibrium where subordinates respect and believe managerial authority (Chron, 2014). Contingency Theory This is a management approach that recognizes each organization as different, which means that each organization faces different situations and requires different ways of managing. This helps the management to understand that there are no universal rules for managers to follow. Instead of looking into the universal rules, the manager must look on to the individual situation and determine the best and efficient way to manage the situation ideally. Different changing circumstances require managers to use different approaches and techniques. There are no simple or complex rules to follow. Managers are able to take decisions based on the conditions (Coulter & Robbins, 2012). Systems Theory The system theory approach explains that organizations take information form the environment and transforms these resources into outputs into the environment. This theory explains the interrelatedness of all parts of an organization and how one change in one area can affect multiple other parts. In this, all the units work together to achieve the organizational goals. Organization depends upon inputs form capital, government regulations, suppliers, information technology, human resources, to receive the output of financial results, products, services and information (Liebler & McConnel, 2012). Organizational theory suits our Organization The organizational theory that closely resembles our organization is the  Contingency Theory. Adapting to the new changes in the environment is the basis for Contingency theory. This theory is important for managerial and organizational success. We have recently adopted Electronic Medical Records, and we are in the adaptation stage of information technology. Manager takes decision based on the current circumstances, which is logical because the units within our organization differ in size, structure, capacity, work activities, and goals. So a universally acceptable theory will not work in all situations. Different situations require different theories of management. Some situation the division of labor and bureaucracy is desirable which supports the classic theory. Other situations structural design becomes effective. Depends on the situation the manager takes the stand. Contingency theory claims that there is no best way to design an organization. There is no written rule on what is the best or the universal solution for the problems in our organization. There is no best way to organize a corporation or to lead a company. Also, the theory that works in our organization may not work for other organizations (Coulter & Robbins, 2012). Compares Management Theories and Styles Managers communication with the subordinates reflects a cluster of styles which the management styles. Managers use different style in different situations. Generally, we can see one style generally emerges as the predominant mode of interaction. Autocratic manager makes independent decisions without much input from subordinates. The manager clearly dictates what, how, when and where things for the employees there is no room for employee initiatives. An autocratic style is least effective and desirable for motivating employees. Another management style is the bureaucratic management style in which the manager follows the rule and ensures that the employees follow the rules â€Å"as well â€Å". They go by the book and the rules and enforced strictly. In this, the employees enjoy less freedom. No exceptions permitted. Participative management is which the manager makes the final decisions, but the employees are involved in this process. Both the manager and the employees involved in the decision making process. Decision made as a cohesive group interaction. Everyone might not accept managers decision. Another type is the Laissez-faire style in which the manager allows employees to manage their own work. No supervision provided. In this, the  individuals should be self-motivated. This can result in disorganization, chaos and lack of direction. Finally, in Paternalistic style the manager makes the decision to benefit the employees. Manager treats employees like children. In this style, the employees become dependent on their manager (Liebler & McConnell, 2012). Management Theory and Style suits our Organization In our organization, there is no one management style that fits to all situations. In my observation, the manager’s shifts form one style to another when they face different groups and situations. When it comes to the policies and procedures, in my observation it is bureaucratic style, top level managers are following autocratic management style, and my immediate manager has a participative style who consults with the employees for decision making. So far I have not encountered any Laissez-faire management style in our place. In the new hire orientation managers follow paternalistic style. For a successful manager, the management style depends on the given situation. If a work environment does not require any close supervision, the managers may select any styles. When employees are unskilled, autocratic style is most efficient. In the current world, changes impacts the manager’s task. It includes economic and political uncertainty, ethical issues, security threats, and changing technology. All these call for different management styles depends on the manager’s involvement. Changes towards Organizational Advancement Organizations deal with challenges in this worldwide economic climate, changing technology and increased globalization. A manager should understand the critical issues and use skills and abilities during challenging times in an organization. A great manager can change your life, encourage employees professionally and personally, energize people to overcome challenges and instill team spirit. Such a manager can make job enjoyable and productive. Manager should create an environment in which the organization members can work to the best of their abilities and think creatively. In order to make the organization better people should support, coach, and find meaning and fulfilment in work. Also have up-to-date information about the new innovative ideas. It is important to be competitive and sustain in the  business world. Develop the networking ability, communicate effectively and be sincere and genuine with others (Coutler & Robbins, 2012). Conclusion In conclusion as we have seen in any organizational performance, managerial ability is very important in creating organizational values. Different management theories and styles range from prohibiting staff from making any decisions to fully delegating the decision-making power. No management style is consistently effective. Situational factors should be taken into consideration in the selection of an effective and efficient management style. The study of organizational theories and management styles is essential in this modern organizational, working environment. References: Chron. (2014). Organizational Theory.

Definitions of Whats Ungrammatical in English

In descriptive grammar, the term ungrammatical refers to an irregular word group or sentence structure that makes little apparent sense because it disregards the syntactic conventions of the language. Contrast with grammaticality. In language studies (and on this website), examples of ungrammatical constructions are usually preceded by asterisks (*). Judgments regarding ungrammatical constructions are often subject to gradience. In prescriptive grammar, ungrammatical may refer to a word group or sentence structure that fails to conform to the proper way of speaking or writing, according to the standards set by some authority. Also called grammatical error. Contrast with correctness. Examples and Observations Designating a sentence as ungrammatical simply means that native speakers tend to avoid the sentence, cringe when they hear it, and judge it as sounding odd. . . .Calling a sentence ungrammatical means that it sounds odd all things being equal--that is, in a neutral context, under its conventional meaning, and with no special circumstances in force.(Steven Pinker, The Stuff of Thought: Language as a Window Into Human Nature. Viking, 2007)Sentences . . . are simply the highest-level expressions of a language, and an ungrammatical string is a morpheme sequence which fails to constitute a meaningful expression of any kind.(Michael B. Kac, Grammars and Grammaticality. John Benjamins, 1992) Examples of Grammatical and Ungrammatical Sentences With Reflexive Pronouns Grammatical Ungrammatical(Terri L. Wells, L2 Acquisition of English Binding Domains. Morphology and Its Interfaces in Second Language Knowledge, ed. by Maria-Luise Beck. John Benjamins, 1998) The smart student thinks that the teacher likes himself.The very happy mother said that the girl dresses herself.The young child said that the pretty woman hurt herself.The man in the blue jacket said that the dog bit himself.The crying father said that the younger boy cut himself.The woman thinks that the student does not like herself.The doctor said that the old man shot himself in the foot.The lawyers think that the four policemen shot themselves.*The man thinks the boy does not like that stupid himself.*The woman said that the little girl saw yesterdays herself.*The taxi driver said that the man hit that careless himself.*The girl said that the teacher laughed at that funny herself.*The soldiers know that the generals like todays themselves.*The student said that the athlete hurt that stupid himself.*The mother wrote that the child laughed at that slow herself.*The man said that the boy was angry with the lazy himself. Distinguishing Between Descriptive and Prescriptive Grammar The sentence below is a garden-variety English sentence, which is descriptively grammatical to any English speaker . . .. I eat bacon and eggs with ketchup. We can form a question based on this sentence as follows: What do you eat bacon and eggs with? This sentence is descriptively grammatical but violates a prescriptive rule; recall that for some, ending a sentence with a preposition (in this case, with) is prescriptively ungrammatical. But now consider this sentence: I eat bacon and eggs and ketchup. When we try to form a question we get the following: *What do you eat bacon and eggs and? No English speaker would utter this sentence (hence the *), but why not? The source sentences look exactly the same; the only difference is that ketchup follows with in the first sentence, and and in the second. It turns out that with, a preposition, functions quite differently from and, a conjunction, and the distinction between the two is part of our unconscious knowledge of English. Studying this unconscious knowledge, revealed in puzzles like this one, allows us to construct a model, or theory of descriptive grammar, a model that attempts to explain why we quite naturally produce grammatical sentences such as What did you eat your bacon and eggs with? but not ungrammatical ones like What did you eat your bacon and eggs and?
