How to Convert Cubic Meters to Cubic Feet

Cubic feet and cubic meters are both measures of volume, the former in the imperial and U.S. customary system, and the latter in the metric system. The conversion is most easily explained with an example problem: How many cubic feet of space is enclosed by a box measuring 2m x 2m x 3m? Solution Step 1: Find the volume of the box Volume in m ³ 2m x 2m x 3m 12 m ³ Step 2: Determine how many cubic feet are in 1 cubic meter 1 m 3.28084 ft (1 m) ³ (3.28084 ft) ³ 1 m ³ 35.315 ft ³ Step 3: Convert m ³ to ft ³ Set up the conversion so  that the desired unit will be canceled out. In this case, we want ft ³ to be the remaining unit. Volume in ft ³ Volume in m ³ x 35.315 ft ³/1 m ³ Volume in ft ³ 12 m ³ x 35.315 ft ³/1 m ³ Volume in ft ³ 423.8 ft ³ Answer The volume of space, in cubic feet, enclosed by a box measuring 2m x 2m x 3m is 423.8 ft ³ Cubic Feet To Cubic Meters Example Problem You can work the conversion the other way. As a simple example, convert 50.0 cubic feet to cubic meters. Start with the conversion factor: 1 m3 35.315 ft3 or 1 ft3 0.0283 m3 It doesnt matter which conversion factor you use, providing you set up the problem correctly. Volume in cubic meters 50.0 cubic feet x (1 cubic meter / 35.315 cubic feet) The cubic feet will cancel out, leaving cubic meters: Volume in cubic meters is 1.416 m3.

Theories explain why the independent variable leads to the dependent variable in each of the hypotheses. You should find a theory or theories that explain each of your hypotheses. (Often one theory will apply to all hypotheses and you do not need to repeat the same information for each hypothesis.) LMX Leader Exchange theory first appeared in the 1970’s and its focus is the member subordinate relationships. This can†¦show more content†¦Leaders and organizations have vested interests in the performance of their subordinates and will employ means suitable to getting them to achieve a task, i.e., enmbracinng a role expectation scenario. Leaders will, by various means, come to identify and use whatever methods necessary to get their subordinates to fit and perform within their roles. The challenge that leaders have is that they will usually have a number of subordinates under their supervision at a time which can be challenging in terms of getting them all to perform as expected. Formal and standard operating procedures call for a relative form of oppression ranging from simple directives to reprimands and threats of termination to get employees to do their work. However the LMX identifies that subordinates are much more motivated to accomplish these roles with interpersonal exchanges between the leader and the aforementioned employee. LMX Implications to Organizational Members Theoretically, then, the LMX model is about operationalizing as many variables as possible in the role-making approach. As such role-development will inevitably lead to differentiated and varied leader-member exchanges.

Price Discrimination Free Essays

Price discrimination Price discrimination is the practice of charging a different price for the same good or service. There are three of types of price discrimination – first-degree, second-degree, and third-degree price discrimination. First degree First-degree discrimination, alternatively known as perfect price discrimination, occurs when a firm charges a different price for every unit consumed. We will write a custom essay sample on Price Discrimination or any similar topic only for you Order Now The firm is able to charge the maximum possible price for each unit which enables the firm to capture all available consumer surplus for itself. In practice, first-degree discrimination is rare. Second degree Second-degree price discrimination means charging a different price for different quantities, such as quantity discounts for bulk purchases. Third degree Third-degree price discrimination means charging a different price to different consumer groups. For example, rail and tube travellers can be subdivided into commuter and casual travellers, and cinema goers can be subdivide into adults and children. Splitting the market into peak and off peak use is very common and occurs with gas, electricity, and telephone supply, as well as gym membership and parking charges. Third-degree discrimination is the commonest type. Necessary conditions for successful discrimination Price discrimination can only occur if certain conditions are met. 1. The firm must be able to identify different market segments, such as domestic users and industrial users. 2. Different segments must have different price elasticities (PEDs). 3. Markets must be kept separate, either by time, physical distance and nature of use, such as Microsoft Office ‘Schools’ edition which is only available to educational institutions, at a lower price. 4. There must be no seepage between the two markets, which means that a consumer cannot purchase at the low price in the elastic sub-market, and then re-sell to other consumers in the inelastic sub-market, at a higher price. 5. The firm must have some degree of monopoly power. Video Diagram for price discrimination If we assume marginal cost (MC) is constant across all markets, whether or not the market is divided, it will equal average total cost (ATC). Profit maximisation will occur at the price and output where MC = MR. If the market can be separated, the price and output in the inelastic sub-market will be P and Q and P1 and Q1 in the elastic sub-market. When the markets are separated, profits will be the area MC, P,X,Y + MC1,P1,X1,Y1. If the market cannot be separated, and the two submarkets are combined, profits will be the area MC2,P2,X2,Y2. If the profit from separating the sub-markets is greater than for combining the sub-markets, then the rational profit maximizing monopolist will price discriminate. Market separation and elasticity Discrimination is only worth undertaking if the profit from separating the markets is greater than from keeping the markets combined, and this will depend upon the elasticities of demand in the sub-markets. Consumers in the inelastic sub-market will be charged the higher price, and those in the elastic sub-market will be charged the lower price. How to cite Price Discrimination, Essay examples

Performance Management for Coaching and Developing - myassignmenthelp

Question: Discuss about thePerformance Management for Coaching and Developing. Answer: Introduction Performance management is of utmost importance for every organization. It helps in different aspects like goal setting and revising, management and coaching, developing and planning rewards and recognition. All these factors are of utmost importance for the overall performance of all the employees. Moreover, it has to be noted that all these factors can only be dealt with properly if the performance of the employees can be fairly promoted and evaluated. In order to do this, he eight fatal flaws if the performance management has to be identified and removed so that the performance of the employees can be boosted up (Chandler 2016). There are eight main flaws or errors existing within an organization that are responsible for the poor performance of the employees. However it must be noted that often the business organizations ate unable to recognize these flaws that already exist within the organization for a long period of time. As a result of this ignorance, the companies often put forward several efforts that go in vain and are often responsible for misleading the efforts that are put forward by the companies for improving the performance of the employees (Pulakos et al 2015). Hence efforts are to be made by the companies to locate these errors or the eight fatal flaws that are existing within their working environment and find out several methods of dealing with these eight fatal flaws. Research There are eight fatal flaws that have been identified by performance management consultant Chandler. These eight fatal flaws are the result of the age old traditional performance management process that is existing within the company. The traditional procedure of the performance management style has developed since the 1950s and has been incorporated within the company since then. This has created a major gap because the working pattern of the employees has undergone several changes over all these years and this was never reflected in the age old traditional performance ideas. So, there was a gap that was created between the age old traditional performance idea and the modern framework of the performance management ideas. It is due to this disconnection or the gap that there were many flaws created in the performance management ideas. These eight fatal flaws have had serious effects on the overall performance of the employees. Discussions The eight fatal flaws of performance management are A theory without evidence is a bad theory It is just a commonly believed theory that the traditional performance ideas will improve the performance of the employees but this however is not backed by any strong evidence. Hence, it is a vague theory (Pulakos et al 2015). There are companies who are every orthodox in nature and are never ready to accept any new changes (Seuring and Gold 2013). However sticking to these old theories only destroy the performance management as a whole rather than developing it. Eye poking The employees will never be able to render their honest feedbacks and their opinions if the managers constantly keep on interfering. Managers are mostly of the belief that they must always judge their employees in order to improve them (Van et al 2015). However, this constant judging often has a very harmful impact on the performance management. This will never allow the employees to open up easily. They will always be under the fear of being judged. No remembrance of the good work The traditional performance management ideas mainly talk about and criticize the weaknesses or the failure of the employees rather than appreciating the strength. Managers usually find it difficult to remember the good work of the employees but they never fail to remember the bad performances. This is common human instinct (Chandler 2016). However the Employees often feel very de motivated if they get good ratings and are appreciated in the beginning of the year but are resent at the end due to slight errors. If the managers focus only on the past and o on the future development scope of the employees, the performance management will definitely be at stake. No man or woman is an island The performance management mainly focuses on the individual performance of the employees and not the working environment which actually has a major influence on the performance of the employees (Chandler 2016). The traditional performance idea mainly emphasizes on the individual efforts including the improvement and specially the weaknesses rather than emphasizing on the influence of the work ambience as a whole. This must be remembered that the work environment is largely in influential on the way the employees perform. No one is a machine The managers often have a habit of imposing too much pressure on the employees. The employees are constantly asked on improve and attain accuracy. However it must be known to the company that the employees are not machines they are human beings and as a result of this, it is very natural for them to have several biasness or inaccuracy. Hence, the managing committee must address to this (Chandler 2016). The employees are not machines This must be remembered that since the employees are not machines, so they must not depend on any non scientific performance appraisals like succession planning, development goal. Often the important business decisions are made based on the biased employee performance data. Competition It is often seen that the company makes a rule of com paring the employees with one another, because they believe that this will improve the potential of the employees and they will work with their full potential. However, this naturally creates several risks among the employees. This will make it impossible for them to work together as a team (Dumay 2014). Pavlovs Dog The traditional performance management ideas believe that the employees will be motivated to work hard only if there are extrinsic motivators (Chandler 2016). However the modern research method says that rather than following the method of rewarding and punishing the employees, the company must focus on several other aspects like cultural aspects of the employees, shared mission and several other such things. Only paying high salary as a performance reward will not be helpful in every way. Conclusion Thereby it can be concluded that in order to develop the performance management of the employees, the company must be able to give up the old performance management ides and must also be very much open towards the adoption of the new ideas. The company must give up its orthodox attitude and must be able to see that if they are to work as per the conditions of the present day scenario, then they are to adopt the new methods that will motivate the employees to work over themselves and increase their performance. The companies must work upon the eight fatal flaws of performance management and must be able to work over that. The company must identify the new methods of improving the overall performance management of the company. Recommendations Theory without evidence is a bad theory In order to fix this fatal flaw, the company must become open towards the modern and new methods by getting rid of the traditional ones. The company must make sure to identify which is working for them and which is not. The company must very carefully design the solution so that the overall performance of the employees will be improved. Nobody remembers the good work The best way to deal with this problem is to develop several areas of conversation between the manager and the employees. The real time feedback will be very much helpful in preventing the biasness which always develops between the employees and the managers. The managers must also be very much open in welcoming several new employees in the conversation so that the employees also feel very much wanted within the organization. This will also give enough space for peer feedbacks. Competition The managers must make sure that there are no comparisons made between the employees. The managers must give bonuses to the group. This will enable the employees to work together and exchange several ideas with one another. This will also help the employees to grow and develop the team spirit.

Thirty Years War Essay Example For Students

Thirty Years War Essay The causes of the Thirty Years War can be traced as far back as the renaissance period. It was during the renaissance that such ideals as secularism, humanism, individualism, rationalism and above all else secularism were first apparent in main stream society. These ideas led to the protestant reformation, which is an even more direct cause of the war. The split of the Catholic Church, as a result of the protestant reformation left Europe in a state of religious turmoil and chaos. The gradual increase in intolerance and religious sectionalism that coincided with the addition of new religions and even more diversity has been marked as the main cause of the Thirty Years War. The effects of the war would prove to be devastating to most of Europe, evidenced by the sharp drop in population, but it was especially devastating to Germany. However, there were some countries and bodies of people that emerged from the conflict improved such as France, Sweden, and the religion of Calvinism. Ther e were many territorial and dynastic issues that figured in the outbreak and conduct of the war as well, but it is believed that these factors did not become important until the middle stages of the war. The territorial and dynastic causes, which go hand in hand, did however, cause the war to continue longer than it most likely would have if religion had been the only motive. The extent of religious motives therefor is debated, but cannot be dismissed. The immediate causes of the war began with the resistance and eventual revolt of Protestant nobles in Bohemia, due to the religious intolerance mentioned before, which was under Hapsburg domination, against the Catholic king Ferdinand. The reasons and causes for its spread throughout Europe include the constitutional frailty of the Holy Roman Empire, the inability of the German states to act in concert, and the ambitions of other European powers. These were the causes that would eventually be responsible for the war lasting as long as it did. We will write a custom essay on Thirty Years War specifically for you for only $16.38 $13.9/page Order now The political motives became more and more prevalent when Sweden entered the war to help the Protestant cause. Sweden did not enter the war for religious reasons at all; they were looking to gain land. Finally it seemed that religion was completely forgotten and abandoned as a cause when Catholic France and Protestant Sweden joined forces against the Catholic Hapsburgs. France was worried that the Hapsburgs were becoming too powerful so they decided to assert their influence into the war. The results and effects of the war and the two peace treaties were highly significant. France replaced Spain as the greatest power in Europe. With Sweden, France had blocked the Habsburg efforts to strengthen their authority in the Empire. At Westphalia, the right of the individual states within the Empire to make war and conclude alliances was recognized. In theory as well as in fact, the most important of these states became virtually autonomous, and German unity was postponed for more than two centuries. The Empire was further dismembered by the recognition of the independence of Switzerland and the seven northern provinces of the Netherlands. Two new powers emerged in northern Germany. France received most of Alsace by the Treaty of Westphalia, and by the Treaty of Pyrenees parts of Flanders and Artois in the Spanish Netherlands and lands in the Pyrenees. The religious settlement at Westphalia confirmed the predominance of Catholicism in southern Germany and of Protestantism in northern Germany. The principle accepted by the Peace of Augsburg of 1555 that Catholic and Lutheran princes could determine the religion practiced in their territory was maintained, and this privilege was extended to include the Calvinists as well. .ue75b2bf065b95af2d78ba133901b9581 , .ue75b2bf065b95af2d78ba133901b9581 .postImageUrl , .ue75b2bf065b95af2d78ba133901b9581 .centered-text-area { min-height: 80px; position: relative; } .ue75b2bf065b95af2d78ba133901b9581 , .ue75b2bf065b95af2d78ba133901b9581:hover , .ue75b2bf065b95af2d78ba133901b9581:visited , .ue75b2bf065b95af2d78ba133901b9581:active { border:0!important; } .ue75b2bf065b95af2d78ba133901b9581 .clearfix:after { content: ""; display: table; clear: both; } .ue75b2bf065b95af2d78ba133901b9581 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ue75b2bf065b95af2d78ba133901b9581:active , .ue75b2bf065b95af2d78ba133901b9581:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ue75b2bf065b95af2d78ba133901b9581 .centered-text-area { width: 100%; position: relative ; } .ue75b2bf065b95af2d78ba133901b9581 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ue75b2bf065b95af2d78ba133901b9581 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ue75b2bf065b95af2d78ba133901b9581 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ue75b2bf065b95af2d78ba133901b9581:hover .ctaButton { background-color: #34495E!important; } .ue75b2bf065b95af2d78ba133901b9581 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ue75b2bf065b95af2d78ba133901b9581 .ue75b2bf065b95af2d78ba133901b9581-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ue75b2bf065b95af2d78ba133901b9581:after { content: ""; display: block; clear: both; } READ: Biotechnology EssayThe Austrian Habsburgs had failed in their efforts to increase their authority in the Empire and to eradicate Protestantism, but they emerged from the war stronger than before.

King Hammurabi of Babylonia - Biographical Profile

King Hammurabi of Babylonia - Biographical Profile King Hammurabi was an important Babylonian king known best for an early law code, that we refer to by his name. He united Mesopotamia and turned Babylonia into an important power. Some refer to Hammurabi as Hammurapi Code of Hammurabi Hammurabi is now synonymous with his code of laws, referred to as the Code of Hammurabi. Five columns of the stele on which his laws were written (inscribed) have been erased. Scholars estimate the total number of legal judgments contained on the stele when it was intact would have been around 300. The stele may not actually contain  laws, per se, as judgments made by Hammurabi. By recording the judgments he made, the stele would have served to testify to and honor King Hammurabis acts and deeds. Hammurabi and the Bible Hammurabi may have been the Biblical Amraphel, King of Sennaar, mentioned in the Bible book of Genesis. Hammurabi Dates Hammurabi was the sixth king of the First Babylonian dynasty about 4000 years ago. We dont know for sure when during a general period running from 2342 to 1050 B.C. he ruled, but the standard Middle Chronology puts his dates at 1792-1750. (Put that date in context by looking at the major events timeline.) [Source] Military Accomplishment of Hammurabi In the 30th year of his reign, Hammurabi removed his country from vassalage to Elam by obtaining a military victory against its king. He then conquered the land west of Elam, Iamuthala, and Larsa. Following these conquests, Hammurabi called himself King of Akkad and Sumer. Hammurabi also conquered Rabiqu, Dupliash, Kar-Shamash, Turukku (?), Kakmum, and Sabe. His kingdom extended to Assyria and northern Syria. More Accomplishments of Hammurabi In addition to being a warrior, Hammurabi built temples, dug canals, promoted agriculture, established justice, and promoted literary activity.

Information Security Planning Essay Example | Topics and Well Written Essays - 750 words

Information Security Planning - Essay Example The company needs to be prepared to combat virus attacks, ingress of unsolicited visitors and possible attacks by competitors on the company's information bank. To provide a safe and working repository of information, it is essential that the company has a well planned security policy in place. 2. The information security should be compliant to IS 17799 standards. This would bring about periodic security audits and would also ensure that there is a clear security policy in line with the objectives of the company. 3. To ensure that there is well defined acceptance criterion and milestones for every security measure and that this adhered to. And that these criterion and the mile stones are in line with the cost and budgeting dictated by the management of the company and to develop a comprehensive information security education policy. 4. To ensure that the company is in a state of readiness to combat potential disasters. Prevention and identification of crime, fraud and theft in the work place by ensuring both physical and logical security. A security review or audit is done to identify the existing security, the degree of protection needed, locate the weaknesses in the system and recommend security steps that are needed. This should also throw out information that has to be secured. Out of the list of jobs that need to be done for the security betterment a priority list is to be made in order of importance for security and the tentative cost for effecting the same. Priorities are laid down based on the company objectives and policies that are critical to company targets. In some of the locations, virus attacks could be frequent and these need to be countered on a priority basis may be because they are eating out on the productive time of the employees of the company and data get lost. In some cases, it might be that the data is getting out of the company through physical means in the form of CDs or flash drives. 3 Establish the feasibility of implementing. A comprehensive list of jobs that has to be carried out and their feasibility in the company needs to be established and accordingly 'what-is-possible' list is produced. 4 Identify whether the planned actions will fit into the budget. Based on the priority and the feasibility list the plan is further fine tuned with another constraint namely, the budget. If the budge should allow then the needed actions may be done, else they get pruned. 5 Need for security is to be fixed. Based on all these factors, the needs for the security is finally fixed and then the requirements are made into one single list. 6 Fix the responsibility for implementing. Using this list, it is important that the responsible person for each activity is fixed and the same is implemented through that specific person. 7 Train the people in the company and create a secure culture. In order to ensure that the implemented security measure continues to bear fruit, the employees of

Civil Disobedience Movement 1930-1934

Civil Disobedience Movement 1930-1934 The Civil Disobedience Movement led by M K Gandhi, in the year 1930 was an important milestone in the history of Indian Nationalism. During the Non-Cooperation Movement, the Indians learnt how philosophical tenets like ‘non violence’ and ‘passive resistance’ could be used to wage political battles. The programs and policies adopted in the movements spearheaded by Gandhi reflected his political ideologies of ahimsa and satyagraha. While the Non-Cooperation Movement was built on the lines of ‘non violent-non-cooperation’, the essence of The Civil Disobedience Movement was ‘defying of the British laws’. Through his leadership to the National Movements, he not only buttressed his political stance but also played a crucial role in unification of the country, awakening of the masses, and bringing politics within the arena of the common man. Causes of the Civil Disobedience Movement Simon Commission: One of the main factors was the Simon Commission. This was formed by the British Government that included solely the members of the British Parliament, in November 1927, to draft and formalize a constitution for India. The chairmanship of the commission rested with Sir John Simon, who was a well known lawyer and an English statesman. Accused of being an All-White Commission, the Simon Commission was rejected by all political and social segments of the country. In Bengal, the opposition to the Simon Commission assumed a massive scale, with a hartal being observed in all corners of the province on February 3rd, 1928. On the occasion of Simons arrival in the city, demonstrations were conducted in Calcutta. The Nehru Report: The British justified that ‘disharmony among the various groups in the country’ was the reason why Indians were not included in the Simon Commission. In 1925 and 1927, Lord Birkenhead, the Secretary of State, had challenged the Indian leaders to draft a constitution to which all parties would agree (keeping the communal disunity in mind). Representative of the congress, the league, the liberals, the Hindu Mahasabha, the central Sikh league, and a number of smaller groups representing labour, business and other interests, met in an all-parties` conference between February and May 1928. A select committee was appointed for the actual drafting of the constitutional scheme. Pandit Motilal Nehru with Tej Bahadur Sapru, sir Ali Imam, Sardar Mangal Singh and Subhas Chandra Bose as its members. The Nehru committee`s report as it was called was submitted on 10 August, 1928. The Nehru report stated that the next immediate step for India must be ‘dominion status’. The Nehru report was approved by the congress at Calcutta in December 1928. Gandhiji sponsored a resolution agreeing to ‘dominion status’ so long as the British accepted the Nehru constitution in its entirety, which should happen in one year. If they did not, congress would `organize a campaign of non-violent non-co-operation` which would include refusal to pay taxes. The failure of the Government to comply with the Nehru report finally made the Congress to launch Civil Disobedience Movement under Gandhiji. The Launch of the Civil Disobedience Movement: First Stage The Congress Committee met at Sabarmati in February, and invested Gandhi and those working with him’ with full authority to lead and direct the Civil Disobedience campaign. Gandhi was urged by the Congress to render his much needed leadership to the Civil Disobedience Movement. Dandi March: On the historic day of 12th March, 1930, Gandhi inaugurated ‘The Civil Disobedience Movement’ by conducting the historic Dandi Salt March, where he broke the Salt Laws imposed by the British Government. Followed by an entourage of seventy nine ashramites, Gandhi embarked on his march from his Sabarmati Ashram to Dandi that is located on the shores of the Arabian Sea. On 6th April 1930, Gandhi with the accompaniment of seventy nine satyagrahis, violated the Salt Law by picking up a fistful of salt lying on the sea shore. They manually made salt on the shores of Dandi. Gandhi-Irwin Pact: In the meantime, the First Round Table Conference was held in 1930, with no Congress member as the participant of the Conference. This led to the meeting of Gandhi and Lord Irwin, the viceroy in March 1931. Here they signed a pact, which came to be known as the Gandhi-Irwin Pact. Accordingly, they agreed on the Discontinuation of the civil disobedience movement by the Indian National Congress participation by the Indian National Congress in the Round Table Conference withdrawal of all ordinances issued by the British Government imposing curbs on the activities of the Indian National Congress withdrawal of all prosecutions relating to several types of offenses except those involving violence release of prisoners arrested for participating in the civil disobedience movement removal of the tax on salt, which allowed the Indians to produce, trade, and sell salt legally and for their own private use. Second Round Table Conference Gandhi attended The Second Round Table Conference in London accompanied by Smt. Sarojini Naidu. At this Conference, it was claimed by Mahatma Gandhi that the Congress represented more than eighty five percent of the Indian population. During this Conference, Gandhi could not reach agreement with the Muslims on Muslim representation and safeguards. Gandhis claim of the Congress representing majority was not endorsed by the British and also the Muslim representative. The final blow to Gandhi came when at the end of the conference Ramsay MacDonald undertook to produce a Communal Award for minority representation, with the provision that any free agreement between the parties could be substituted for his award. Thus, the Second Round Table Conference proved to be futile for the Indians and Gandhi returned to the country without any positive result. The political scene in India thereafter assumed an acute dimension. The Viceroy, Lord Willington, in the absence of Gandhi has adopted the policy of repression. The Gandhi-Irwin Pact was violated and the Viceroy took to the suppression of the Congress. The Conservative party, which was in power in England, complied with the decision to assume a repressive stance against the Congress and the Indians. The Congress was also held responsible by the government to have instigated the Red Shirts to participate in The Civil Disobedience Movement, led byKhan Abdul Ghaffar and provoking the cultivators of U.P to refuse to pay land revenue. Adding to this was the serious economic crisis that took hold of the country. Under such circumstances, the resumption of The Civil Disobedience Movement was inevitable. Renewal of the Civil Disobedience Movement: Second Stage The Congress Working Committee took the decision to restart The Civil Disobedience Movement, as the British government was not prepared to relent. Gandhi resumed the movement in January, 1932 and appealed to the entire nation to join in. The Viceroy was also informed of the stance assumed by the Congress. The police was given the power to arrest any person, even on the basis of mere suspicion. Sardar Patel, the President of Congress and Gandhi were arrested, along with other Congressmen. Though the second phase of The Civil Disobedience Movement lacked the organization that marked its first phase, nonetheless, the entire nation put up a tough fight and the movement continued for six months. Communal Award, 1932 Meanwhile, the failure of the Second Round Table conference convinced Mr. MacDonald to announce the Communal Award on August 16, 1932. According to the Award the right of separate electorate was not only given to the Muslims of India but also to all the minority communities in the country. The Award also declared untouchables as a minority and thus the Hindu depressed classes were given a number of special seats, to be filled from special depressed class electorates in the area where their voters were concentrated. Under the Communal Award, the principle of weightage was also maintained with some modifications in the Muslim minority provinces. Principle of weightage was also applied for Europeans in Bengal and Assam, Sikhs in the Punjab and North West Frontier Province, and Hindus in Sindh and North West Frontier Province. Though the Muslims constituted almost 56 percent of the total population of Punjab, they were given only 86 out of 175 seats in the Punjab Assembly. The Muslim majority of 54.8 percent in Punjab was thus reduced to a minority. The formula favored the Sikhs of Punjab, and the Europeans of Bengal the most. The Award was not popular with any Indian party. Muslims were not happy with the Communal Award, as it has reduced their majority in Punjab and Bengal to a minority. Yet they were prepared to accept it. In its annual session held in November 1933, the All India Muslim League passed a resolution that reads; Though the decision falls far short of the Muslim demands, the Muslims have accepted it in the best interest of the country, reserving to themselves the right to press for the acceptance of all their demands. On the other hand, the Hindus refused to accept the awards and decided to launch a campaign against it. For them it was not possible to accept the Untouchables as a minority. They organized the Allahabad Unity Conference in which they demanded for the replacement of separate electorates by joint electorates. Many nationalist Muslims and Sikhs also participated in the conference. The Congress also rejected the Award in Toto. Gandhi protested against the declaration of Untouchables as a minority and undertook a fast unto death. Though he managed to sign the Poona Pact with Dr. B. R. Ambedker, the leader of Untouchables in which the Congress met many of the Untouchables demands, the Communal Award was a blow to Gandhiji and he finally decided to suspend and withdraw mass satyagraha on 14th July, 1933. The movement ceased completely on 7th April, 1934.

Joe Keller in All My Sons Essay -- Arthur Miller

How to Make Joe Keller Look Bad KELLER: Say, I ain’t got time to get sick. MOTHER: He hasn’t been laid up in fifteen years. KELLER: Except my flu during the war. MOTHER: Huhh? KELLER: My flu, when I was sick during†¦the war. MOTHER: Well, sure†¦(to George) I mean except for that flu. (George stands perfectly still) Well, it slipped my mind, don’t look at me that way. He wanted to go to the shop but he couldn’t lift himself off the bed. I thought he had pneumonia. GEORGE: Why did you say he’s never-? KELLER: I know how you feel, kid, I’ll never forgive myself. If I could’ve gone in that day I’d never allow Dad to touch those heads. GEORGE: She said you’ve never been sick. MOTHER: I said he was sick, George. George: (going to Ann) Ann, didn’t you hear her say-? MOTHER: Do you remember every time you were sick? GEORGE: I’d remember pneumonia. Especially if I got it just the day my partner was going to patch up cylinder heads†¦What happened that day, Joe? In the above lines, Arthur Miller pulls back the veil that has been hiding Joe Keller’s past in All My Sons. Not only are these lines critical to the remainder of the play’s events, but many of the characters also switch emotions almost instantly. With the significance and delicateness of these lines at stake, a director has the responsibility of conveying the language to the audience with only a few pre-existing stage directions as aid. One major way to convey these lines is to remain consistent with how he/she is portraying each character to make them still feel convincing to the audience. If directed effectively, Joe Keller’s departure from all prior characterization will be even more noticeable. In addition to other possibilities, the... ...l be no happy ending. The chaos George brought into Act II will only magnify after this speech. This section is in essence, the loss of stability in the Keller family. Keller is reduced to a shell of his former self as the audience takes on the beliefs of Chris through the remainder of the play. This scene will hopefully result in frustration towards Keller so that his â€Å"You’re a boy, what could I do!† (Miller 2.646) speech does not merit much pity. We realize that although Keller was misunderstood, he lived a lie too long. At the play’s end, this scene acted from my viewpoint should give the audience the feeling that even though Keller’s suicide is tragic, it is these lines that killed him.

Far from the madding crowd Essay

1. Chronicle the relationship between Bathsheba Everdene and one of the three men (Oak, Boldwood or Troy) in her life. Who was the most to blame for the difficulties encountered in the course of their relationship? (One or both? ) I will begin by giving an account on the relationship between Bathsheba Everdene and Gabriel Oak. After completing this I will come to a conclusion on who was most to blame for the difficulties encountered in the course of their relationship. When Farmer Oak and Bathsheba first encounter in the book, Oak sees a carriage with Bathsheba sitting on top, the carriage is full with furniture. This lady interests Oak and as the carriage is about to leave he â€Å"followed the vehicle to the turnpike gate some way beyond the bottom of the hill, where the object of his contemplation now halted for the payment of the toll. † It is noticeable that Oak is interested in this woman but the scene unfolds as Bathsheba refuses to pay the turnpike keeper the two pence he would like. â€Å"Let the young woman pass,† is what Gabriel said as he draws near and hands the keeper the money. This meeting introduces the two characters to the reader for the first time, but they do not know that they will both play an important part in each other’s lives. Not long after the meeting, Gabriel sees Bathsheba from a â€Å"birds eye view†, this is when he realises that he feels something towards Bathsheba. â€Å"Having for some time known the want of a satisfactory form to fill an increasing void within him, his position moreover affording the widest scope for his fancy, he painted her a beauty. † This is the moment when Oak sees Bathsheba riding a horse on her back in a way she would not have if she knew she were being watched. Bathsheba does not know that Oak is watching. This is when Oak knows that he is in love with her. As she rides back he approaches her and brings up the fact he saw her earlier, this makes her blush as she apprehended that he had seen her. Oak has became so in love with her that he would wait for her to come past the hedge every day, he â€Å"had reached a peak of existence he never could have anticipated a short time before. † Oak chooses to marry Bathsheba but he is mislead by Bathsheba’s aunt told him that she has many sweethearts already. Bathsheba finds him to tell him that the statement was not true. This leads him to think that she wants to marry him and tells her that his is doing well in life and that Bathsheba may have her own piano. â€Å"Would hate to be thought men’s property in that way,† is Bathsheba’s reply, meaning she likes the idea of marriage but does not like the outcome of all the responsibility afterwards. Also Bathsheba is not totally stunned by Gabriel’s property and is not impressed by the idea of having a â€Å"little piano. † Later on in the book, after Oak hears that Boldwood has proposed to Bathsheba she asks Oak to deny all rumours about her getting married but Oak refuses. He goes on to say he will give her his point of view about her actions. Oak re-approaches her and she decides to take serious measures. â€Å"I cannot allow any man to – to criticize my private conduct! † â€Å"Nor will I for a minute. So you’ll please leave the farm at the end of the week! † As soon as Bathsheba dismisses Oak she once again needs him as the sheep are in trouble and will die unless Oak can help them. Bathsheba knows the sheep are at stake so even though she was reluctant to call back Oak at first she does so. At first he does not want to come back as Bathsheba was impolite in the way she asked for him to stay, but in the end he does. Gabriel then realises that Bathsheba may need him more than he thought, as she does not no how to run a farm properly, this gives Gabriel the thought that he may be able to have a relationship with her. Gabriel’s chances of a relationship with Bathsheba are ruined when Troy arrives in the book. Oak warns Bathsheba that she should not get involved with him, but she is already in love and does not take any concern to what is being said. Bathsheba later goes off to Bath with Troy where Oak believes she is going to turn down Troy but instead they come back as a married couple. Oak still loves Bathsheba though and shows her his devotion to her one night when a storm is brewing; he helps save the hayricks while Troy and the rest of the village are drunk. After accounting the relationship between Bathsheba and Oak, I will now who was the most to blame for the difficulties encountered in the course of the relationship. I cannot see how Gabriel Oak was the most to blame for the difficulties encountered in the course of all the mens relationships with Bathsheba. I believe that it is a combination of both Boldwood’s and Troy’s. This is because if Boldwood was not so desperate for love he would have realised that the valentines card Bathsheba sent him was simply as a prank, â€Å"What fun it would be to send it to that silly old Boldwood. † Instead Boldwood takes this seriously as he searches for love, he continuously approaches Bathsheba saying that he is in love with her, and that they should get married, â€Å"My life does not belong to me any more, Miss Everdene, but to you. I’ve come to propose marriage to you. † I believe that if Boldwood had accepted the fact that the card was actually only sent as a prank, then he would never have asked Bathsheba to marry him. Therefore some of the difficulties encountered would never have happened. I also believe Troy has a part to blame in the difficulties encountered, as his flirtatious ways and seduction techniques begins to make Bathsheba fall in love with him. Troy only likes Bathsheba as she happens to be a very pretty lady, he would never have treated a women he did not find attractive in this manner. This is shown in the way he speaks to her upon their first encounter â€Å"Thank you for letting me see such a beautiful face! † Before Bathsheba and Troy get married he tells Bathsheba how he has seen a women far more beautiful than her, this is only an attempt to make sure he marries her. Again if Troys trickery and flirtatious ways were not to have happened some of the difficulties would never have happened. I cannot see how Gabriel was to blame for any of the difficulties, as when Bathsheba was with either Boldwood or Troy he simple let whatever to carry on, he did not get in the way. This is because he thought that aslong as Bathsheba was happy with the man she was with, then that would make him happy, even though he would not be able to be with her. So to conclude I believe that both Troy and Boldwood are to blame for the difficulties encountered in the course of Bathsheba’s relationship with all three of the men.

Brady Act Background Checks, History, and Application

Brady Act Background Checks, History, and Application The Brady Handgun Violence Prevention Act is perhaps the most controversial federal gun control law enacted since the Gun Control Act of 1968, and several events in the U.S. led to its creation and enactment. In an effort to deny guns to those who would misuse them, it requires firearms dealers to perform an automated background check on prospective buyers of all rifles, shotguns or handguns. Brady Bill History On March 30, 1981, 25-year old John W. Hinckley, Jr. tried to impress actress Jodi Foster by assassinating President Ronald Reagan with a .22 caliber pistol. While he accomplished neither, Hinckley did manage to wound President Reagan, a District of Columbia police officer, a Secret Service agent, and White House Press Secretary James S. Brady. While he survived the attack, Brady remains partially disabled. Driven largely by the reaction to the assassination attempt and Mr. Bradys injuries, the Brady Act was passed, requiring background checks on all persons attempting to purchase a firearm. These background checks must be performed or applied by federally licensed firearms dealers (FFLs). NICS: Automating the Background Checks Part of the Brady Act required the Department of Justice to establish the National Instant Criminal Background Check System (NICS) which can be accessed by any licensed firearms dealer by telephone or any other electronic means for immediate access to any criminal information on prospective gun purchasers. Data is fed into the NICS by the FBI, the Bureau of Alcohol, Tobacco, and Firearms, and state, local, and other federal law enforcement agencies. Who Cannot Buy a Gun? Between 2001 and 2011, the FBI reports that over 100 million Brady Act background checks were performed, resulting in more than 700,000 gun purchases being denied. People who may be prohibited from purchasing a firearm as a result of data obtained from the NICS background check include: Convicted felons and people under indictment for a felonyFugitives from justiceUnlawful drug users or drug addictsIndividuals who have been determined to be mentally incompetentIllegal aliens and legal aliens admitted under a non-immigrant visaIndividuals who have been dishonorably discharged from the militaryPeople who have renounced their American citizenshipPeople under domestic violence restraining ordersPeople convicted of misdemeanor domestic violence crimes Note: Under current federal law, being listed on the FBI Terrorist Watchlist as a suspected or confirmed terrorist is not grounds for denial of a firearm purchase. Possible Outcomes of a Brady Act Background Check A Brady Act gun buyer background check can have five possible outcomes. Immediate Proceed: The check found no disqualifying information in the NICS and the sale or transfer can proceed subject to state-imposed waiting periods or other laws. Of the 2,295,013 NICS checks done during the first seven months the Brady Act was enforced, 73% resulted in an Immediate Proceed. The average processing time was 30 seconds.Delay: The FBI determined that data not immediately available in the NICS needs to be found. Delayed background checks are typically completed in about two hours.Default Proceed: When a National Instant Criminal Background Check System check cannot be completed electronically (5% of all checks), the FBI must identify and contact state and local law enforcement officials. The Brady act allows the FBI three business days to complete a background check. If the check cannot be completed within three business days, the sale or transfer may be completed although potentially disqualifying information might exist in the NICS. The dealer is not required to complete the sale and the FBI will continue to review the case for two more weeks. If the FBI discovers disqualifying information after three business days, they will contact the dealer to determine whether or not the gun was transferred under the default proceed rule. Firearm Retrieval: When the FBI finds that a dealer has transferred a gun to a prohibited person due to a default proceed situation, local law enforcement agencies, and ATF are notified and an attempt is made to retrieve the gun and take appropriate action, if any, against the buyer. During the first seven months, the NICS was in operation, 1,786 such firearms retrievals were initiated.Denial of Purchase: When the NICS check returns disqualifying information on the buyer, the gun sale is denied. During the first seven months of NICS operation, the FBI blocked 49,160 gun sales to disqualified people, a denial rate of 2.13 percent. The FBI estimates that a comparable number of sales were blocked by participating state and local law enforcement agencies. Typical Reasons for Denial of Gun Purchases During the first seven months in which Brady Act gun buyer background checks were performed, the reasons for denial of gun purchases broke down as follows: 76 percent - Criminal history of a felony8 percent - Criminal history of domestic violence6 percent - Criminal history of other offenses (multiple DUIs, non-NCIC warrants, etc.)3 percent - Criminal history of drug abuse3 percent - Domestic violence restraining orders What About the Gun Show Loophole? While the Brady Act has blocked more than three million gun sales to prohibited purchasers since taking effect in 1994, gun control advocates contend that up to 40 percent of gun sales occur in â€Å"no questions asked† transactions that often take place over the Internet or at gun shows where, in most states, background checks are not required. As a result of this so-called â€Å"gun show loophole,† the Brady Campaign to Prevent Gun Violence estimates that about 22% of all gun sales nationwide are not subjected to Brady background checks. In an effort to close the loophole, the Fix Gun Checks Act of 2015 (H.R. 3411) was introduced in the House of Representatives on July 29, 2015. The bill, sponsored by Rep. Jackie Speier (D-Calif.), would require Brady Act background checks for all gun sales including sales made over the Internet and at gun shows. Since 2013, six states have enacted similar laws.

Astronomy Final Essays

Astronomy Final Essays Astronomy Final Essay Astronomy Final Essay Number each question here according to its number in the Final Examination document provided by your instructor. 1. (a) Kepler’s 3rd law P^2 = a^3 (P = period in years; a = distance in AU) 75^2 = a^3 a = (75^2)^(1/3) = 17. 78 AU. (b) The further comets are from the sun, the slower they travel; therefore, it spends longer at the further distance. 2. (a) Star B is farther away. Its parallax is less. The closer a star is, the more its position changes against the background as the earth revolves around the sun. That is what parallax is. (b) 20 parsecs. One parsec = distance at which a star has a parallax of 1 arcsecond) Since this parallax is 1/20 as large, its distance is 20 times greater. (c) 65. 2 light years. (1 parsec = 3. 26 ly * 20) 3. (a) 10m would have the greater light gathering power (b) Both of the telescopes are in vacuum. The 10m one has area Pi r ^2, with r = 5m and the 2m one has r = 1. The ratio of Pi 5^2/Pi 1^2 = 25. Twenty-five times more light falls onto the l arge telescope. (c) The 10m telescope has a â€Å"Greater† light gathering power. (d) The factor would be about 25 times the light gathering power. e) Normally, light gathering power ratios are just the ratios of the areas. Due to the atmosphere on earth, there could be some absorption, however, since the wavelength is not specified, it wouldn’t hold true. Since the atmosphere acts like a gradient index lens, the amount of light that hits the earth telescope would have a very small increase thus refracting light towards the telescope. If there were no atmosphere, it would have continued at a larger angle and missed the telescope. 4. (a) d = 10,000 =100Mpc 100 (b) d = V d = 10,000 = 200Mpc H0 50 c) If universe is flat and composed mostly of matter, then the age of the Universe is 2 3H0 In the case of a very low density of matter the extrapolated age is larger. Age of universe = 1 H0 So the Universe is directly proportional to H0 5. Gx = GMm/r^2 G_new = GMm / (3r)^2 = GM m / 9r^2 (a) The force is 1/9 times (b) 9 times weaker 6. 15000/3000)^4 (a) The blue star is 625 times (b) more luminous Essay (Answer all nine Questions) Complete these answers in your own words. Follow instructions in the Final Examination document. Answer all questions according to the instructions. Number each question here according to its number in the Final Examination document provided by your instructor. 1. a. H-R Diagram A (Very Young Cluster) b. H-R Diagram D (Young Cluster) c. H-R Diagram B (Old Cluster) d. H-R Diagram C (Very Old Cluster) Similar to the sun, stars will spend a majority of their life on the main sequence. We can view this by looking at the H-R diagram, which shows a ‘dense concentration’ of stars along a constricted belt from the upper left to the lower right. The mass of the star determines where on the main sequence it is located and how soon the star will move away from the main sequence. The age of the cluster can be estimated by viewing a cluster of stars on the HR diagram in reference to where they end on the main sequence. 2. Seasonal variation of a planet depends on the frequency with which any given side of the planet changes its position with respect to the star. For a planet like Uranus, which has a high tilt (73 deg), the same side always faces the sun and hence its always summer on one side and winter on the other. Thus we can conclude that seasonal variation is directly related to the tilt of the planet. 3. a. Among the given planets, D has the minimum tilt – So the answer is D, which shows max seasonal variation. b. A planet will be geologically active if it has a high density, since that would assure wide variety of rocks and minerals and ores and less amount of hot gases; so among the planets, A has the highest density and is the most geologically active. 3. The younger surface would go to Moon A due to the fact that Moon B possesses many craters, which are clearly visible as the picture represents (this is clearly shown by the illuminated spots). Genesis shows that the craters were developed over time. Since moon A has far less craters, this means it was recently formed thus making it the younger moon. 4. a. The Hubble Expansion: As the distance increases, the apparent brightness of the object decreases meaning it becomes darker the farther away it gets. This technique determines the relative distances of similar objects. In addition, a phenomenon called the Doppler effect can be used to determine the velocity of an object. The sonic Doppler effect is caused by compression of sonic wave fronts, which can be generalized to electromagnetic radiation and other wavelike phenomena. The magnitude of an objects Doppler shift is a function of its radial velocity relative to the observer. Velocities of various objects, such as stars and galaxies, have been tabulated in our vicinity. An almost straight line with positive slope was obtained when the distance was plotted for various galaxies against their velocities. This shows us that the farther away an object is, the greater the velocity. This lends support to the Big Bang theoryif the universe does indeed expand in a manner consistent with the Big Bang model, then two objects that are close to each other should have smaller relative velocities than in comparison with distant objects. b. Cosmic Microwave Background (CMB): This is the result of theorized energetics, which was discovered in 1965 by Penzias and Wilson. Their discovery showed microwave radiation emanating from all directions in our observable locality of the universe. As predicted by the Big Bang Model, the universe is filled with plasma at high temperatures. As a result, hydrogen can only exit as plasma with an ambient temperature of about 3000K. c. Primordial abundance of light elements: This is the observed abundance of elements in the universe. Examinations through the spectra of various objects shows us that helium makes up about 23% of observable mass in the universe, which is entirely too large to be accounted for by stellar fusion. Since stellar nucleosynthesis makes the abundance of lighter nuclei hard to explain, the Big Bang model theorizes that the nuclei were created during the fierce explosion. . Due to the numerous negative effects on the body, human space travel remains physiologically difficult. Many of these affects are due to longs include: muscle atrophy, skeletal deterioration, slowing of cardiovascular functions, red blood cell production decrease, balance disorders, and weakening of the immune system. In addition, without the appropriate protection, space exposure becomes a sever threat due to the environmental diff erences between space and earth – especially the lack of oxygen and pressure. Interstellar space travel consists of many problems, which makes human travel extremely difficult – even in the future. One problem is the amount of fuel needed for long-duration flights. In addition, we have to worry about the damaging effects of galactic radiation. Also consider the loneliness and boredom of generations of humans spending their entire lives aboard a spacecraft. In order to get to the nearest star system beyond our Solar System (Alpha Centauri), we would have to travel 4. 3 ly with a constant flight velocity of 50 km/s; which is roughly about 25,000 years. Although that velocity would allow us to escape the Solar System, it would still take 250 centuries to reach our closest star system. It is very unlikely that humans will be able to equip themselves with the technology, at least anytime soon, to make contact with extraterrestrial life. Even if we took into account the many factors in the Drake equation, galactic civilizations are probably spread out like small islands throughout space. Even if the average lifetime of extraterrestrial civilizations is 1 million years, our most optimistic estimates suggest that each is separated by ~300 ly. Additionally, thousands of sorties would have to be launched toward candidate star systems for any hope of successful extraterrestrial contact. In summary, although it may never become feasible, interstellar space flight is both uneconomical and impractical now and anytime in the foreseeable future. 6. Galileo Galilei was a very influential astronomer because he defended his beliefs in a time when the Roman Inquisition was in power. Galileo defended his idea of heliocentrism against the Inquisition and was put on house arrest. This did not stop him from doing what he loved. While on house arrest, he made observations and continued his work. His contributions to astronomy include the discovery of three moons of Jupiter, the idea that the nature of each planet is unique, identification of sunspots, and his continued examinations of the Milky Way and sea tides. 7. As of March 23, 2012, 763 exoplanets (extrasolar) within our Milky Way have been discovered by satellites such as the Kepler. Consequently, these satellites have been flying through space, uncovering hundreds of new planets within our galaxy. Recently, two planets (Kepler 62e and 62f) have been discovered, which orbit a sun similar to ours but cooler. These planets are at just the right distance that allows water to remain liquid an essential must for a planet to support life. In addition, these planets are very similar to the size of Earth. Because of their size and orbits, it is highly likely that they are either rocky or watery. The two planets are located 1,200 light-years away in a five-planet system orbiting a star dubbed Kepler-62. 8. The milky is a flat disk surrounded by a halo with a bulge at the center. Within the disk, lay clouds of gas and dust that amount to around 15% of the mass of stars. Although we cannot see the nucleus due to all the scattered dust radio, infrared, and x-ray telescopes allow us to see through the dust and show us that the core contains a dense swarm of gas and stars and a massive black hole. A majority of the gas and dust clouds lie within the disk. In addition, bright stars gather into spiral arms winding in an outward direction. The location of our solar system is about 26,000 ly from the center, lying on the inner edge of the spiral arm. 9. D C B A

A Closer Look at Nashville TN Research Paper Example | Topics and Well Written Essays - 500 words

A Closer Look at Nashville TN - Research Paper Example As the discussion highlights  Tennessee infant mortality rate per 1000 live births was 7.4. This was a significant drop by 22% compared to 2003. Based on the 2011 records, the number of white infant deaths was 361 with a mortality rate of 6.0, whereas, the number of black infant deaths was 211 with a rate of 12.8 per live births. The leading causes of infant death in the state were birth defects, preterm birth and low birth-weight and accidents. The accidental deaths were majorly owing to strangulation and suffocation that tended to occur in bed. The 5th leading cause of death in infants is the Sudden Infant Death Syndrome.This essay discusses that there are some identifiable risk factors contributing to the prevalence of the top five diseases. Environmental factors such as air pollution contribute to the prevalence of heart disease, cancer and lung disease. Other risk factors include smoking, obesity, physical inactivity and a poor diet. The risk factors identified in Tennessee ar e similar to national and local records. Since 2005-2013, smoking in the country remained fairly stable at 25% among adults with a 15.7% decline among the youths. Obesity also remained fairly stable at 35% in adults and 17% in youths. Similarly, also obesity ranks high in Tennessee across all ethnic groups and ages.  A number of epidemiological methods are used in the gathering of data. For example, the morbidity survey that focuses on the collection of morbidity data of both the sick and the well.

What are variables Essay Example | Topics and Well Written Essays - 1500 words

What are variables - Essay Example A variable is anything whose value can vary. For instance age is a variable as age varies for different persons. Variables need not be numerical always. Gender is a variable as it consists of two text values ‘male’ and ‘female’. An attribute refers to specific values of the variable. For example, the variable gender has two attributes- male and female. The variable agreement may have five attributes- (a) strongly agree, (b) disagree (c) neutral (d) agree and (e) strongly agree (Trochim, 2006).Every variable has some attributes.For studying cause- effect relationship, the distinction between independent variable and dependent variable must be clear. The independent variable is what the researcher manipulates. The dependent variable is that which is affected by the independent variable. The independent variable is the cause or treatment and the dependent variable is the effect or outcome. For example, while studying the effects of traffic rule awareness campai gns to reduce accidents, the program is the independent variable and the achievements are dependent variables. A variable should be exhaustive and mutually exclusive. Exhaustive means that a variable should include all possible responses. For this purpose, list all the important attributes and use a general category like â€Å"other† to represent remaining ones. Also, variables should be mutually exclusive. It means that no one should be able to have two attributes simultaneously. Operationalization The meaning of a research study depends on how objectively the phenomena under consideration are observed. So developing a reliable and valid set of procedures for measuring the variables is crucial for the validity of research study (Operational Definitions, 2005). The first step for an operational definition is to specify the constructs. How observations are made, what is observed, how observations are to be recorded have to be specified accurately. Sample Sampling is the proces s of selecting units from a population so that by studying the sample, it would be able to generalise results back to the population. Related to generalisation is the concept of external validity. Validity refers to the approximate truth of conclusions (Trochim, 2006). External validity refers to the degree to which conclusions in the study would hold for other persons in other places at other times (Trochim, 2006). There are two major methods for selecting sample for generalisation. One is called sampling model. In it, the population to be generalised is identified and a fair sample is drawn to conduct the research. Since the sample is representative of the population, the generalisations are applicable to the population. The second approach is called proximal similarity model. The term proximal similarity was suggested by Donald T. Campbell. In this approach, several generizability contexts are considered and theories are developed as to which situation or context is more similar to the study and which are less similar. By doing so, it is possible to generalise the results of the study to other persons, places or times that are more like the study (Trochim, 2006). The population to be generalised is called theoretical population. The population that is accessible to the study is called accessible population. The list of accessible population from which sample is drawn is known as sampling frame. For example, if a phone survey is to be done with a phone book, the phone book is the sampling frame. The sample is the group of people, who are selected for the study. But, the group that actually completes the study is the sub sample of the sample only. There is a distinction between random selection and random assignment. Random selection refers to how sample is selected. Random assignment refers to how different treatments are assigned to the sample selected for study. In sampling, the units are usually people and they supply responses. A response is a specific m easurement value. A statistic is used to look at the responses of the entire sample. Mean, median,

Model for the Up-gradation of the E-mail System Essay

Model for the Up-gradation of the E-mail System - Essay Example You would agree that a large project management team definitely requires managerial capabilities. The model again fails to address soft skills which again is a necessity for any management function. There are other project management bodies like the PMI, each with their own body of knowledge. Currently there is no shared version of bodies of knowledge among them and there could exist conflicts among these models. "The intent in making these points is not to argue that one BoK is "better" than another - hopefully the different models will slowly converge - but that as it stands the PMI model is unnecessarily, and even dangerously, delimiting the scope of the discipline." (Morris, P.12). These are three major shortcomings attributed to the PMBOK model. As you may be aware, the model was introduced in 1987 and due to its inadequacy, again modified in 1988 under the guidance of Professor Alan Stretton. Even this model has not been found to be satisfactory be the Project Management Instit ute. Newer and more efficient models have been developed in the last decade and two of them are discussed here. This model was developed by Kevin Forsberg, Hal Mooz, and Howard Cotterman in the late 1990's. This model was developed in consultation with hundreds of project managers and consultants. The advantage of this project is that concepts of management are also integrated into the model, something which was lacking in the PMBOK model. A graphical representation of the model is given here. (Project management models in the new century). It can be seen that almost all aspects that go into a project is represented here. It also shows that executive support is essential by showing this aspect as the platform on which the whole project is resting. The model is shown as a wheel with and axle. Four essential elements are incorporated into the model. "These four elements are: a common vocabulary, teamwork, the sequential project life cycle, and management elements." (Project management models in the new century). The wheel has the following elements namely, Project Requirements, Organizing Options, Project Team, Project Planning, Opportunity and Risk, Project Control, Project Visibility, Project Status, and Corrective Action. Leadership is given an important role and is shown as the rim of the wheel. In other words, it is the leadership rim that holds the project together. The concept here is that, as the wheel rotates, it moves forward on the axle. The axle contains the following elements namely, User, Concept, System, Plan, Sourcing, Implementation, Deployment, Operations, and Deactivation. This is the actual process by which a project will move forward. So as the project wheel turns (begins) it moves along the process until it is completed (deactivation). Three more essential elements are shown in the axle namely Technical, Business, and Budget aspects of the project. Another important feature of this model is that the axle and the wheel rest on two pillars teamwork and common vocabulary. As mentioned earlier the whole structure rests on the platform of executive support. Almost all respects of a project is shown here in simple and lucid manner. Most importantly this model

Peace Building and Community Development Essay Example for Free

Peace Building and Community Development Essay Community development is a multi-faceted activity that has different ends. It also has different requirements depending on the needs of people inside the community. Development can be achieved through sustaining small and medium businesses, ensuring education for all, managing inclusion and diversity, keeping peace and order, and creating comprehensive disaster management. Through these, a community can be sustainable. Peace and order is an important aspect of community development. Without peace and order, it is impossible to unite the members of the community and enforce other sustainability projects. It will also be difficult for the community to prosper if chaos is widespread. Businesses will perish and investors will be elusive. This shows that peace building is important for a community. According to Maiese (2003), the United Nations defined peace building as an interplay of â€Å"capacity building, reconciliation, and societal transformation†. For other organizations, the short-term goals are more evident—peace building revolves around promoting peace in an immediate situation. In hindsight, despite the contradiction, both definitions are true. They also help create the whole concept of peace building for communities. Peace building can concentrate on resolving current issues between constituents. It involves moderating by authorities or other members of the community to maintain understanding between parties. On the other hand, it is also creating a society where the constituents are educated and transformed so that they do not only know peace but also lives peace. In these terms, education plays an integral role. This creates a community which is not only dependent on intermediaries but with self-regulation of peace as well. In the end, a community filled with peace-loving citizens is a community where peace has been built.

Self Charging Cellphones Using Piezoelectric Zno Nanowires Engineering Essay

Self Charging Cellphones Using Piezoelectric Zno Nanowires Engineering Essay This paper aims at the transformation of mechanical energy, sound energy and various kinds of disturbances to electrical energy using piezoelectric materials. Using piezoelectric materials it is easily possible to convert any kind of mechanical stress to electrical energy and vice versa .Thus the sound produced during the usage of devices like cellphones can be converted to electrical energy and thus can be utilized for recharging the device. This paper presents a model of piezoelectric ZnO nanowire transducer for a gadget like mobile phone prototype of the power scavenging circuit, and the overall circuit for charging the mobile battery using the generated energy. INDEX TERMS : Charge generation, Diaphragm type , PVDF copolymer ,piezoelectric polymer , zinc oxide nanoparticle , Key depressions, Piezoelectric effect. INTRODUCTION A mobile phone (also known as a cellular phone, cell phone and a hand phone) is a device that can make and receive telephone calls over a radio link while moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network.A mobile phone uses a battery which serves as a power source for phone functions. The battery basically has one of the most important considerations when choosing a mobile phone.The basic cellphone batteries used are Lithium ion batteries which are of pouch format .These batteries are basically soft type with flat body.The talk-time battery time for a basic cellphone is considered to be six hours. Thus this short lifetime causes problem in case of battery rundown when there is no charging point available or during an important phone call. This problem of battery life in a mobile phone can be solved by using the unused power existing in form of sound ,vibration ,human activities, structures and environmental sources. Among these, one of the promising sources of recovering energy is from the vibrations generated by the key depressions of any keypad integrated device such as a mobile phone. Primarily, the selection of energy harvester as compared to other alternatives such as battery depends on two main factors, cost effectiveness and reliability. Conversion of mechanical low frequency stress into electrical energy is obtained through the direct piezoelectric effect, using a rectifier and DC-DC converter circuit to store the generated electrical energy. There are three primary steps in power generation: (a) trapping mechanical AC stress from available source. (b) Converting the mechanical energy to electrical energy using piezoelectric transducer. (c) Processing and storing the generated electrical energy. The mechanical output can be in the form of burst or continuous signal depending on the cyclic mechanical amplifier assembly. Depending on the frequency and amplitude of mechanical stress, one can design the required transducer, its dimensions, vibration mode and desired piezoelectric material. The energy generated is proportional to frequency and strain and higher energy can be obtained by operating at the resonance of the system. PIEZOELECTRIC EFFECT The idea of this paper is to trap the vibrations of sound and other mechanical vibrations in a cellphone and use it to recharge the cellphone. Thus this creates a easier energy harvesting method. A conventional piezoelectric ceramic that is composed of a perovskite ceramic crystals, which consist of a small, tetravalent metal ion, usually of titanium or zirconium mineral, in an arrangement of lattice of larger, divalent lead or barium metal ions, and O2- ions (Figure 1). Under such arrangements they attain tetragonal or rhombohedral symmetry on the crystals. Individual crystal has a dipole moment. Refer Figure 1 b. Preparation of piezoelectric ceramicinvolves the following steps. The required proportions of Fine PZT powders of the component metal oxides are mixed. Then, it is heated to form a uniform powder. Now the piezo powder is mixed with an organic binder to get structural elements of desired shape (discs, rods, plates, etc.). The mixture is exposed to fire for a specific time and temperature program. It shapes the piezo powder particles and attains a dense crystalline structure. Finally the elements are cooled, then shaped or trimmed to various specifications, and electrodes are applied to the appropriate surfaces. Fig (1a) NOTE: Above the Curie point which is the critical temperature, the perovskite crystal in the fired ceramic element acquires a simple cubic symmetry with no dipole moment (Figure 1a).Below the Curie point, each crystal exihibits tetragonal or rhombohedral symmetry with a dipole moment (Figure 1b). Adjacent dipoles that are connected form regions of local alignment are called domains. This gives a net dipole moment to the domain, and thus a net polarization. The direction of polarization among all the adjacent domains is random, so the ceramic element has zero overall polarization (Figure 1a). Figure(1.b) CRYSTAL STRUCRURE PIEZOELECTRIC CERAMIC The alignment of the domains is done by exposing them to a stronger and direct current electric field,at a temperature slightly below the Curie point (Figure:2b). Through this special polarizing treatment, domains that are aligned closer with the electric field expand at the expense of unaligned domains, and the element lengthens in the direction of the field. When the electric field is withdrawn, nearly all the dipoles are locked into a configuration of closer alignment (Figure:2c). The element now is said to have permanent polarization, the permanent polarization, and is permanently elongated. Fig(2) POLARIZING OR POLLING A PIEZO CRYSTAL The tension produced by the mechanical compression on a poled piezoelectric ceramic element alters the dipole moment due to which a voltage is created. voltage of the same polarity as that of the poling voltageis generated by the compression produced along the direction of polarization, or tension perpendicular to the direction of polarization. Tension opposite to the direction of polarization, or compression parallel to the direction of polarization, generates a voltage with polarity opposite that of the poling voltage i.e., Disk is stretched. These actions are called generator actions .The ceramic element converts the mechanical energy (due to compression / tension) into electrical energy. This action is used in fuel-igniting devices, solid state batteries, force-sensing devices, and many other products. Values for compressive stress and the voltage (or field strength) generated by applying stress to a piezoelectric ceramic element are linearly proportional up to a material-specifi c stress. And also true for applied voltage and generated strain. fig (3): The piezoelectric materials are advantageous in that they do not rely on external power sources (e.g., batteries or alternating current (AC) power) for continued operations, unlike strain gages  ¬Ã‚ ber optics , wireless sensor nodes, micro-electromechanical systems (MEMS) devices , and other types of sensing systems. Unfortunately, PZT and PVDF suffer from fundamental limitations intrinsic to their material. Although piezo-ceramic PZT transducers possess high piezoelectricity and d33 piezoelectric constants approximately 200-400 pC N-1 , they are extremely brittle, have high loss factors, and are characterized by highly hysteretic behavior . On the other hand, piezoelectric polymers such as PVDF and PVDF-copolymers are  ¬Ã¢â‚¬Å¡exible, conformable, and can be fabricated to different sizes and thicknesses . However, they possess considerably lower piezoelectric constants are compared to PZTs (10 pC N-1) and require intricate mechanical stretching to enhance their bulk  ¬Ã‚ lm piezo-electricity. Furthermore, both PVDF  ¬Ã‚ lms and PZTs require high-voltage poling so as to enhance their piezo-electricity. Thus, in order to use piezoelectric transducers for sensing applications in complex laboratory and  ¬Ã‚ eld environments, it is desirable for them to simultaneously possess high piezoelectricity and excellent mechanical properties. On the other hand, the nanotechnology domain offers a diverse suite of new materials and composite fabrication methodologies for high-performance piezoelectrics . Among the plethora of nanomaterials, zinc oxide (ZnO) nanostructures (e.g., nanowires, nanosprings, and nanoparticles, among others) can be readily synthesized and exhibit inherent piezoelectricity . BLOCK DIAGRAM The basic block diagram of the proposed model is shown in Fig. below. It consists of 3 main blocks, (a) piezoelectric power generation (b) rectification (c) storage of DC voltage. AC voltage is generated from the piezoelectric material which is rectified by the rectification block and then it is stored in a storage device such as a battery. Fig (4):BLOCK DIAGRAM DESCRIPTION (PROTOTYPE MODEL OF PIEZOELECTRIC MATERIAL FOR MOBILE PHONES ) A diaphragm assembly comprises at least two piezoelectric diaphragm members arranged in a stacking direction. An interface layer is situated between adjacent piezoelectric diaphragm members. The interface layer in the stacking direction is displaceable and incompressible or resilient. The interface layer permits lateral movement of the adjacent piezoelectric diaphragm members relative to the interface layer in a direction perpendicular to the stacking direction. The interface layer can comprise, for example, an incompressible liquid or a semi fluid or a compressible gas. A gasket can be used to seal the substance in the interface layer if necessary. Fig. 5. Basic model of diaphragm type piezoelectricity generation. 1. Electrodes 2. Piezoelectric material (PVDF) 3. SiO2 4. n-Si 5. Hole for the central part of film to deform itself CIRCUITRY The figure illustrates the overall circuit diagram of the entire process. The rectifier shown in the Fig maybe either a full wave rectification circuit or a half wave rectification circuit based on the combination of diodes or a voltage double rectifier. Since a diode is being used in the rectifier, a p-n junction diode or a Schottky diode can be used. The Schottky diode has a threshold voltage which is lesser than that of a p-n junction diode. For example, if the diode is formed on a silicon substrate, a p-n diode may have a threshold voltage of approximately 0.065 volts while the threshold voltage of a Schottky diode is approximately 0.30 volts. Accordingly, the uses of Schottky diode instead of p-n diode will reduce the power consumption required for rectification and will effectively increase the electrical charge available for accumulation by the capacitor. When the electromotive force in the piezoelectricity generation section is small, a Schottky diode having a low rising volt age is more preferable. The bridge rectifier section provides rectification of the AC voltage generated by the piezoelectric section. By arranging the rectification section on a monolithic n-Si substrate, it is possible to form a very compact rectification section. A typical diode can rectify an alternating current-that is, it is able to block part of the current so that it will pass through the diode in only one direction. However, in blocking part of the current, the diode reduces the amount of electric power the current can provide. A full-wave rectifier is able to rectify an alternating current without blocking any part of it. The voltage between two points in an AC circuit regularly changes from positive to negative and back again. In the full-wave rectifier shown in Fig the positive and negative halves of the current are handled by different pairs of diodes. The output signal produced by the full-wave rectifier is a DC voltage, but it pulsates. To be useful, this signal must be smoothed out to produce a constant voltage at the output. A simple circuit for filtering the signal is one in which a capacitor is in parallel with the output. With this arrangement, the capacitor becomes charged as the voltage of the signal produced by the rectifier increases. As soon as the voltage begins to drop, the capacitor begins to discharge, maintaining the current in the output. This discharge continues until the increasing voltage of the next pulse again equals the voltage across the capacitor. The rectified voltage is stored into a storage capacitor as shown in Fig., which gets charged upto a pre-decided value, at which the switch closes and the capacitor discharges through the storage device or the battery. In this way the energy can be stored in the capacitor, and can be discharged when required . Fig 6:Circuit diagram of the whole process. RESULTS The material used for the current application is a PZT with 1.5 Mpa lateral stress operating at 15Hz. The output power produced is 1.2W. The energy/power density is 6mW/cm3.The output voltage is 9V [8]. The volume of the material used is 0.2cm3. This voltage can be used to produce the required amount of charge after being processed. CONCLUSION The design of the proposed energy conservation system for mobile phones and has been presented in this paper. The design helps to provide easy energy harvesting technique for mobile phones.The design presented here will be quite effective in providing an alternate means of power supply for the mentioned devices during emergency.The design is improved by implementing nanowires .The implementation of nanowires reduces the size of the system and also improves the efficiency on the other hand increases the cost of the system.Thus this design converts the vibrartion due to sound and key depression into electrical energy to recharge the mobile phones.

Physics of Dog Mushing :: sport Physics Dogs Dog Racing

Acceleration/Velocity Acceleration and velocity are mostly dependent on the number of dogs, the quality of the dogs, and how well the dogs have been trained, but it also can depend on friction and inertia. The lager mass an object has the the more weight it has and the more inertia it has. Weight effects acceleration by increasing friction. Friction is f =  µN where  µ is the coefficient of friction, N is the normal force, and f is friction. The normal force is equal to mass times gravity assuming no other downward forces are applied. Therefore the more weight in both sled gear and musher the dogs have to haul the lower the velocity and the slower the acceleration will be due to friction between the runners and the ground. Inertia effects acceleration because inertia is the tendency of objects to ether stay at rest or stay in motion. In this case since the point is to move we are more concerned about staying at rest. When starting the dogs have to pull harder to get the sled moving then they do to keep it moving to both overcome the effects of inertia and to change the fiction from static friction to kinetic friction. Force/Work Force is necessary to start all motion, and in the presence of friction force is needed to maintain a constant velocity. In mushing a vast majority of the force comes from the dogs, and depending on the musher as a small amount to no force comes from the musher (assuming flat terrain). Mathematically F = ma where "F" is force, "m" is mass, and "a" is acceleration. this tells us that if the velocity is constant then the sum of the forces equals 0(F = 0). this doesn't mean the dogs aren't applying any force it just means that they are only applying enough force to over come any friction that might be resting the forward motion. The dogs apply this force by pulling on the tug lines which leads to a gangline which is attached to the sled. some mushers place a shock absorber between the sled and the gangline to both ease jolts from the dogs accelerating from a stop and to reduce the jolt on the dogs from large bumps in the trails. Work The dogs are only doing work when they are accelerating because W = Fd where W is work, F is force, and d is distance.
