In first equation there are less number of nucleons involve so there nuclear force will be less and thus it will be more reactive there fore they are less stable while on the other hand when the nucleons are more in number as it is in step 2 therefore the re will be strong nuclear force, will be less reactive and more stable. 2c) When the fusion reaction occurs so at that time two atoms combine and produce larger atom and release high energy in the form of binding energy of nucleons. As this process continues till the formation of iron Fe 56,so at that time binding energy of electron is minimum that is most negative and now if the more heavier atom is required to be formed so more energy will release Q3 a i) Data: Redshift = z = 0.13 Speed of light =c= 3 * 108 ms-1 Hubble constant = H0 = 70 kms-1Mpc-1 Distance to the galaxy = r=? Formula: 1.

Q3 b ii) The answer is not in the book. Or no relative material is in the book kindly search yourself Q#4 General relativity and quantum gravity depart from Newton’s theory. The gravitational force of attraction is described by Newton’s law of gravity. Einstein’s theory of general relativity describes the interaction between space and the matter within it. When the masses become very large, this theory provides a more accurate description of gravity than does Newton’s law. General relativity also predicts the existence of gravitational radiation, which is emitted by massive objects that undergo an acceleration. There is good evidence that such radiation i s being generated by binary pulsars. A convincing theory of quantum gravity has yet to be formulated, but it will involve quanta referred to as gravitons which interact with everything. Einstein’s theory of general relativity reproduced all the old results of Newton, but without even using the idea of weight. The core of general relativity is the interaction between ‘space’

Macro-Economics Essay Example | Topics and Well Written Essays - 1500 words

Macro-Economics - Essay Example Aggregate demand is the economy-wide demand for goods and services by all economic agents and aggregate supply is the total goods and services produced. The macroeconomic model of aggregate demand and aggregate supply determines the relationship between aggregate price level and aggregate output in the short run as well as the long run through the interaction of all the markets (Mankiw, 2008). The aggregate demand curve, that is the relationship between AD and aggregate price level, is drawn for a given supply of money. It slopes downward since higher the price level, lower is the real money balances, on account of the Quantity Theory of Money, and so lower is the demand for goods and services. The aggregate supply curve is the relationship between total goods and services produced in the economy and the price level. The long run AS supply curve is vertical while, in the Keynesian macroeconomic model, the short run AS curve is horizontal since prices are assumed to be sticky in the short run. In the long run, changes in aggregate demand affect prices but in the short run, changes in aggregate demand affects output only. Keynes proposed that low aggregate demand is responsible for low income and high unemployment that characterize economic downturns. This is in contrast to the classical view that aggregate supply, depending on the supply of labor capital and technology, determines national income. To reconcile these two views, it is considered that in the long run, prices are flexible so that aggregate supply determines the national income while in the short run, prices are sticky so that aggregate demand determines national income (Mankiw, 2008). The IS-LM model of aggregate demand represents the interaction of the goods and money markets. The IS curve is a downward sloping relationship between rate of interest and output that is derived from the equilibrium in the goods market. Here, planned expenditure, given by the total of consumption, investment and government expenditure in the closed economy and in addition, net exports in the open economy, is equal to the actual expenditure, given by the total output. Consumption depends on the disposable income after paying taxes, investment on interest rates, through the loanable funds market, and exogenously given government expenditure and net exports. In the money market, the LM curve denotes the relationship between rate of interest and output such that real money supply is equal to the real money demand. Even though money supply and prices are exogenous in the short run, real money demand depends positively on output (through the quantity theory of money) and rate of interest (through the theory of liquidity preference). The intersection of the IS and LM curve gives the equilibrium rate of interest and output. Thus, the interaction of the money market, the goods market and the loanable funds market determines equilibrium output and rate of interest. This may or may not be equal to the full employment output which is achieved in the long run when prices are flexible (Mankiw, 2008). Role of Government Policies If the economy is producing less than full employment output at equilibrium, the government can increase output by either fiscal policy or monetary policy. Fiscal policies to

Quality Management Concept

Quality Management Concept This report mainly discusses quality management. The concept of quality management and its four different quality management schemes adopt in commercial operations. And briefly discuss about quality controls and their benefits to the customers by Adidas Company which engaged in London Olympics 2012 as official partner. Through out the first question discussed about the quality management concept and features which use to identify quality. And quality in terms of business and services perspective and how quality can be define with customer satisfaction. Also how quality management can be measured. As second step briefly discussed about four different quality management schemes adapt to commercial operations and the similarities and differences of each quality management schema. And discuss its importance of communication and record keeping within the organization. Select an organization which engaged in London Olympics 2012 and did quality audit and gave recommendations to do the modifications. I have selected Adidas Company which provides equipments, shoes, clothes and accessories to London Olympics 2012. As third part of the report briefly discussed about the information made available to customers and importance of effective marketing. Importance of user and nonuser surveys when determining customer needs. And what are the consultation methods used by the represented groups to encourage the participation for London Olympics 2012. Finally evaluate the value of complaints procedure and quality improvements. As fourth question of the report analyse the role of self assessment of own quality management system. And discussed about the staff consultation to implement effective quality scheme and I have proposed new modifications and ideas to improve the existing quality management schema. Question One: Concept of Quality Management Quality is the totality of features and characteristics of a product or service that bear on its ability to satisfy stated or implied needs. Quality programs include Fitness for use. (Is the product or service capable of being used?) Fitness for purpose. (Does the product or service meet its intended purpose?) Customer satisfaction. (Does the product or service meet the customers expectations?) Conformance to the requirements. (Does the product or service conform to the requirements?) Define quality in terms of business and service provision The business and service organization is profited by selling their products and services. To keep the quality of the products and services these companies must practice the quality management. The quality must be including in all steps of production process of product or service. The best quality is key concept to improve sales as well as marketing tool. The quality is key element of Competition in the market. The organization is manufacturing products. The product must be capable to fit for use, confirm the manufactures requirements. And also meet its intended purpose as planned by the business organization. As same as the organization is service provided one, then the service must be fit to the requirements of the company, it must meet the intended purpose of a particular service of the company and confirm its requirements. Define quality in terms of customer satisfaction The customer is the most important person of the business and service organizations. These organizations manufacturing goods and services to full fill the requirements of the customers. The organizations existence is depends on the customer satisfaction. The products and services must be able to meet the customers expectations by the product and service. The product and the service must be value its price paid by the customer. The customers are attracted to the best quality products and services. After consuming product or service the customer is satisfied and, the customer thinks to buy the same product or service again, then product or service represents best quality. Then the customer has confidents to buy other new arrivals. Due to best quality some trade marks are more popular. These products and services satisfy the customers in higher level. How quality management can be measured Quality management can be measured in different ways. Number of scraped goods, reworks done for produce goods, additional material or inventory which do not use for particular production, warranty repairs or service done for sold goods, customer complaints made for sold goods and services, liability judgement made for goods and services, product recalls and product corrective actions taken to products. The above mentioned measurements are considerably high the products or services are not in a bests quality. Question Two: Four different Quality Management schemes appropriate to commercial operations The Quality Management Systems (QMS) scheme helps organisations to meet customers quality requirements and relevant regulatory requirements, while also enhancing customer satisfaction and achieving continual improvement of its performance. Describe the rationale underpinning four quality schemes commonly adopted by commercial operations Quality Planning Quality planning is the process of identifying the quality standards according to the products and services which produce in the organization and determining how to satisfy the particular quality standards. Identify the particular quality policy, scope statement, product description, quality standards and regulations as products and services. Then use cost benefit analysis, benchmarking, flowcharts and design experiment methods to determine the current quality levels and identify the gap between the identified quality standards and current position. Then determine quality management plan, checklists and input to other processes, as the final stage. The above mentioned quality planning methods represents the quality position of the organization and produce best quality products and services. The quality planning is also carrying out as quality management scheme. Quality Assurance Quality Assurance is the process of evaluating overall production performance on a regular basis and assures the productions satisfaction in terms of quality standards. Evaluate quality management plan, evaluate results of quality control measurements and operational definitions. And use quality planning tools, techniques and quality audits for evaluate overall production performance. Then give confidents of production satisfaction in terms of quality standards. So quality assurance is also a quality management scheme. Quality Control Monitoring products and services to determine if they comply with relevant quality standards and identifying ways to eliminate the poor performance of the production process. Monitoring work results, quality management plan, operational definitions and checklists in the production processes of product or service. Then use quality control methods of inspections, control charts, pareto diagrams, statistical sampling, flowcharting and trend analysis to identify lower performance of the production process. Then do quality improvements, change acceptance decisions, do rework, completed checklists and do process adjustment as quality improve decisions of quality control scheme. Total Quality Management Implementing quality improvement programmes within the organization to maintain the particular quality standards. Maintaining quality programmes in all stages of production process (planning, training and induction, process control, field testing, product design validation, process validation, test and evaluations, quality audits, maintain and calibration) and among the staff(senior manager, production manager and production staff) who are working in the organization. Identify main similarities and differences between quality schemes Similarities All these quality schemes are based on particular quality standards of the product or service. Quality control and quality planning schemes take corrective actions to minimize the poor performance of the production process. Quality assurance and quality control evaluates the current quality levels of the organization and come up to a decision. Total quality management and quality control change the quality practice continuously. Differences In quality planning schema based only on the previously planned quality levels. Quality assurance schema consider only about the level of quality assurance. Quality control schema continually improves the performance of the quality practice. Total quality management implementing quality programmes, if usable or non usable as stage of the production process. Explain importance of communication and record keeping in quality schemes By communicating quality schemas give the new ideas to develop the quality practices within the organization. Communication identifies the purpose for the weak points of the low quality production steps. And also identifies the best schema to carry out in the quality management system. Record keeping compare the past results and identify the weak points within the production process of goods and services. Can be used to draw statistical diagrams and identify the major defects and improve the particular stages of the process and for analysis purposes. Record keeping makes easy, the benchmarking processes with other organizations. Question Three: Quality Controls and their benefits to the customers Adidas Company is one official partner of the London Olympic 2012. That provides shoes, clothes, accessories and equipment for London Olympic 2012. Assess the information made available to customers and the importance given to effective marketing Information is available through internet, television and other media. They are highly use internet to send information to the customers. Because they can take the customer feed back through internet faster than other mediums. Information availability improves higher buyer in, improves market presents through easy access using internet, feed back is high therefore significantly can be improve customer satisfaction, faster transaction times, more efficient order processing and due to less manual work the fewer errors. Can be able to keep existing customers introducing new styles, attract new customers using different prices and styles, can be able to make a trend in the market using marketing and increase market share, taking feedback from customers and improve the quality and new arrivals to the market. Evaluate the benefit of user and non user surveys in determining customer needs User surveys Users are the existing customers. To keep them the new products and style must be introduce for that their customer satisfaction is more important. By doing user surveys can be able to identify their needs, expectations, and the trend in the market. And also can be able to identify limitations. The user surveys can be easily done from the audience of London Olympics 2012. Non user surveys Non users are also customers. They were non users may be due to unaffordable prices or dislike to the products. From these surveys the Adidas can identify the reason and can be able to produce products for their desire while keeping the standards of the company. Olympics is in 2012 from these surveys helps introduce new fashions. Examine the methods of consultation employed to encourage participation by under represented groups Publish the growth undertaken after joining as a partner of London Olympics 2012; Show the sales improvements within that period through media discussion and press conference. The new arrivals can be market through the Olympic 2012 through internet and television. Release newspaper articles about, the benefits gain by participating London Olympics2012. Investigate the value of complaints procedure and analyse how each is used to improve quality Identify weaknesses The customers identify weakness points of the products. That can be size requirements, colour requirements and etc. Then the Adidas can change the products as customer perception. Identify low quality points Some products can be broken only in one place, all the times (must be continuous customer) If they received considerable number of complaints about a particular cloth or shoes or etc. then Adidas can identify this low quality point and will be able to improve quality. Complaints about after sales services Can be complaint about the staff who provided after sales services. Then the Adidas can improve the quality of the employees who are employing in their company. Question Four: Principles of Quality Management Role of self assessment in order to determine an Organizations quality management The quality policy must develop as first step by the Management team. The quality improvement team must establish representing all the departments of the company. Quality must be measures continuously to reduce quality awareness errors. The corrective actions must be taken for quality issues and zero defects planning must be done to the future productions. The identified errors can be removal through daily quality checking and reduces the error making purposes. Then critically recognise the particular point will help to improve the quality. Employees must be educating about the quality standards and issues and the importance of quality work and quality council must work daily basis and planned a zero defects day. Explain the stages of staff consultation necessary for effective implementation of a quality scheme Staffs are responsible for the production. Quality of the product or service is depending on the quality work done by the staff. During the planning stage to after sales services stage, the staff must do the quality work. The surveys can be done through the staff about quality scheme of the company. The documents are also filled according to the quality standards. The workforce planning is also should be change for effective implementation of quality scheme. The time management and material management must be quality for the effective implementation. Train the new staff for the particular positions then the errors will reduce and improve the quality scheme. Propose new systems or modifications to existing systems that could improve service quality The quality standard and policies must be change according to new trends and customer perceptions. Continues improvement is more practical because it is not cost very much.

Canberra Bushfires :: essays research papers

Canberra Fires of 2003 The Canberra bushfire began on Saturday 18th January 2003, with reports suggesting that it was started by a Lightning Strike, to the north of Canberra. In the few hours the few hours that proceeded, the fires raged out of control. Another fire close to the one started by the lightning, ended up joining it, creating a massive fire front, roaring towards Canberra. No warning could prepare the people of Canberra for what was happening. They did not have much time to fight the fires. They were instructed by the fire crews to leave their houses and flee. Over 300 homes were lost. One suburb, Duffy, was hardest hit. Just about every house in this one suburb was destroyed or partly burnt by the fires. Damage was reported to be in the hundreds of millions, with many treasured possessions lost, never to be recovered again. This story of survival was heard on the radio station Nova 97.9. A neighbour from Duffy lived near a farm. The man who owned the farm didn’t even try to save his home. He knew that he would never save it, so he went down the road, took his hose and helped his fellow neighbour save their home. That home was saved. However, the man with the farm lost his home. His neighbour said that he saw him the next day sleeping in his tractor with his dog on the side of the road. That is a story of Aussies doing their best to look out for their mates. Canberra was declared a disaster area by the Federal Government. Millions of dollars was donated by the people of Australia to help those people in crisis in Canberra. Millions of Aid Money was also handed out by the Government to those whose homes were destroyed. In one day an entire large are of Canberra was lost. Due to one fire. This fire was also fueled by strong winds of 50 km/h fanning the fire front and propelling it towards Canberra. Due to the fact that Canberra is surrounded entirely by bush and scrub area, the fire had lots of natural fuel to help it along. The entire surrounding area of Canberra is Trees and farms. This would have helped the fire a lot to travel faster than usual. Preliminary observations of the gardens of houses affected by the bushfires highlighted the importance of trees and shrubs that retain dead leaves and other material.

The Bureaucracy in the United States Essay Example

The Bureaucracy in the United States Essay Example The Bureaucracy in the United States Paper The Bureaucracy in the United States Paper Some examples of bureaucracy in the United States are: the International Revenue Service, which collects taxes from citizens. The Federal Bureau of Investigation, which looks into crimes for American citizens. The Postal Service, which delivers mail to citizens and the Health Care Financing Administration, which reimburses states fro money, spent on health care for the poor. An Iron Triangle is the relationship among an agency, a committee and an interest group. For example the Department of Veterans Affairs is a triangle made up of the house and Senate committees on Veteran Affairs and Veteran’s organizations. These three would make up a strong alliance with each other. The department would do what the committee wanted them to do and in return get political support and budget appropriations and the committee would do what the department wanted and in return get votes and campaign contributions. The Department of Housing and Urban Developing is also and Iron Triangle because it works closely with mayors and real-estate agents. Another example of this is the Department of Agriculture, which works closely with form agencies. The Small Business Administration works closely with congress and loan programs that make it so strong that even the most popular President cannot beat them. The Federal Communications Commission works with broadcasters and heads of cable-television companies. They however are feeling the pressure of separate demands coming from both the television guys as well as the broadcasters. The common government agency today is not an iron triangle but an issue network. An issue network consists of people in Washington based interest groups, on congressional staffs, in universities and think tanks, and in the mass media who regularly debate government policy on a certain subject. The networks are split along political, ideological, and economic lines. When Reagan became president he filled these jobs with people who were from that part of the issue network holding free-market or anti-regulation views. When Bush became president he filled them with more centrists member of the issue network. Clinton then brought back the consumer activist and Bush Jr. will probably follow in his father’s footsteps and fill these positions again with centrist members.
