Principles of Macroecomomics - Essay Example 295). Figure 1. Disposable income and MPC Source: Miles and Scott (2005, p. 295) It can be found in all textbooks in macroeconomics that the MPC is related with the Keynesian income multiplier. Following Mankiw (2009, p. 373-374), the Keynesian multiplier process begins when government spends. For example, let us say that government spends ?20 billion (as mentioned earlier, Mankiw’s discussion used dollars not pounds). If the MPC is ? or 0.75 then the ?20 billion spent by government is received by society as factor payments of ?15 billion wherein, in turn, 75% of the ?15 billion are spent by those who received the payments. In turn, the factors who received the payment of 75% of the ?15 billion will spend ? of their income or 75% of 75% of ?15 billion and the chain goes on continuously. According to Mankiw (2009, p. 373), the process continually repeats and goes on indefinitely resulting into a total spending illustrated by Table 1. Table 1. MPC and multiplier resulting from i nitial government spending of ?20 billion Source: Mankiw (2009, p. 373) Based on the above, from the Keynesian perspective, government spending multiplies or increases income received by society based on the marginal propensity to consume (Mankiw 2009, p. 373-374). Based on Mankiw (2009, p. 374), the multiplier based on the MPC can be derived as: . The foregoing is equal to the following (Mankiw 2009, p. 274): . Economists are concerned with the MPC because the MPC is intimately related with the Keynesian income multiplier. It follows from the multiplier = 1/(1-MPC) that the higher MPC or the marginal propensity to consume, the higher the multiplier is. A low MPC implies a low Keynesian multiplier. As implied by our earlier discussion, Baumol and Blinder (2009, p. 160) discussion is similar but Baumol and Blinder’s take-off point for the concept of the marginal propensity to consume is disposable income rather than plain income. Disposable income refers to that part of income left after taking out taxes and the transfers payments received are added (Baumol and Blinder 2009, p. 157). Based on Baumol and Binder (2009, p. 157), at the macro level, disposable income or DI is: DI = GDP - Taxes + Transfer payments = GDP - (Taxes – Transfer payments) = Y - T. Miles and Scott (2005, p. 298) provides an interesting illustration of the Keynesian multiplier based on the modelling of the Keynesian perspective through the consumption function. In Figure 2 below, the 45 degree line is the level where spending equals income while PEo is the initial level of spending by consumers, government, and investors. A rise in government spending leads aggregate spending to PE1 such that following the Keynesian perspective, an increase in income from Yo to Y1 results. Figure 2. Marginal propensity to consume and multiplier Source: Miles and Scott (2005, p. 298) Miles and Scott (2005, p. 298) preferred, however, to say that â€Å"the multiplier shows how much demand rises once all agents have adjusted to an event that generates a change in some component of demand.† Following, this interpretation, it is important to study the MPC because initial spending by government or an increase in spending by any one or the consumer, government, or business can increase aggregate spending â€Å"once all agents have adjusted† to the initial increase in spending by any or all of the economic agents. Miles and Scott (2005, p. 299) even pointed out that â€Å"the larger is the propensity to con

Enterprise infrastructure - Essay Example It is subdivided into smaller sections within a large portal. An EIP allows users to get information in the desired context. It categorizes information for easy access to users. It also allows employees to collaborate by sharing information regardless of their geographical locations. An EIP allows an organization to disseminate information efficiently. It also enables an organization to consolidate all its websites in a single platform. In addition, it provides quick access to information within an organization. EIP allows employees in an organization to access relevant personalized information quickly. EIP can also provide targeted employee information depending on their roles preferences. One of the most important guidelines for determining the best information sharing approach is information security. In any communication, the message is supposed to remain confidential. It should not reach unintended parties. An EIP is relatively secure for sharing organizational information because various categories of users can access different portals. The system allows authorized users to login to respective accounts and get personalized information. The second factor that determines the approach of sharing information within an organization is the accessibility of the information. A good system of sharing information should be easy to use and widely available. It should not be confined to specific places alone. It should enable users to get what they want at any place and time. The third factor that determines information sharing strategy in an organization is the speed of dissemination. Information should reach the recipient within the shortest time possible. A good information sharing system should, therefore, transmit the information to the recipient within a short period. An organization should encourage the use of three information flows within the organization. The three information flows are downward, upward and

How to write a professional resume Essay Example | Topics and Well Written Essays - 1000 words

How to write a professional resume - Essay Example This is a very important document that is used in different organizations for selection as well as recruitment purposes of the employees. A professional resume is carefully designed and the layout is catchy such that it helps the reader to grasp all the necessary information about a person without any hassle. A close analysis of the resume for Paul DiCicco shows that a resume is a document that contains important information about a prospective job candidate. Firsts and foremost, it can be noted that a resume is focused and it does not meander in as far as the subject matter is concerned. For instance, the name of the candidate as well as personal contact details are presented on top of the information. This makes the document visible such that it can be read clearly by any person without labouring to access the information needed about a candidate. Professional resume writing requires considerable effort as well as practice since this document determines the chances of success or fa ilure of the prospective job seeker in his endeavour to secure employment in a certain organization. Another important consideration when writing a resume is that a short career summary should be inserted at the beginning of the resume. This helps to describe the job applicant and it also gives information about the prospective candidate. A potential employer can easily read the resume and he can gain insight about the qualities of the person applying for a certain position in the company. Information about the candidate is written in a brief and clear manner such that it can be understood by any person who has browed the resume. The main purpose of writing a brief summary is that it captures all important details about a job applicant without presenting unnecessary details that may congest the document. Potential employers do not have time to read all details about a candidate on a resume since they go through hundreds of resumes on a daily basis. It is therefore important to captu re the attention of a potential employer through designing a resume in a professional manner. Professional experience The other important consideration when writing a resume is related to professional experience. As shown in the resume for Paul DiCicco, it can be seen that the section for professional experience should contain important information about the job candidate such as the period he has done the same type of work. This helps the employer to evaluate the capability of the job applicant’s potential of performing the same task should he be hired to fill the vacant post. This section also helps the employers to screen the number of candidates vying for the same post since the resume contains information about experience possessed by different individuals. This section of the resume also helps the employer to evaluate if he is dealing with the right candidate. In most cases, work experience is very important since helps the employer to save money in as far as training a nd development of the employee is concerned. The number of years in terms of experience is also very important when writing a resume. This helps the employer to select the right person who has knowledge in the work being offered. Education This is one of the most important sections of a resume. This section is presented in a reverse chronological order, that is from top to bottom. The highest level of education or qualification is presented on top and this is followed by other less important qualifications in order of the years they were obtained. When recruiting candidates for certain posts within an organization, the employers are more interested in the professional qualifications of the person involved. These

President Bashar Al Assad Politics Essay

President Bashar Al Assad Politics Essay President Bashar al-Assad has also deep contacts and friendship with Hezbollah group and Iranian Mahdi Army. In the current situation of Syria between President Assads army and protesters Assad has been assisted by fighters of Hezbollah and Shiite recruited by Yemen and other countries. According to now.mmedia.me the army troops of Mahdi Army has entered in South Syria through Druze Mountain to assist President Assad in controlling protesters in the country. This intervention of Mahdi Army was a clear message to progressive socialist party leader of Syria Walid Jumblatt, who was raising his voice to get help for uprising of Syria internationally, that this uprising is going to be crushed by President Bashar with the help of Iranian guards. Iran has shown its full and deep commitments to Syrian regime by helping the regime in Damascus where a severe crackdown was implemented by President Bashar with the full assistance of Iranian Mahdi Army. This severe crackdown of Mahdi Army resulte d in the brutal killings of 6,000 protesters in Damascus. A video is been leaked in YouTube (http://www.youtube.com/watch?v=FIQOMlk9WcI) in which a sniper soldier of Mahdi Army has been captured by the Syrian rebels, in the video this prisoner is admitting that he was sent to Syria to kill Syrian protesters to help President Bashar Assad. This sniper is the member of Mahdi Army in Iraq that means President Bashar has strong relations and contacts with Mahdi Army. Hezbollah Group: President Bashar called the Hezbollah group to crush down the uprising voices in Syria. Hezbollah is the group that has advanced artillery and well trained soldiers to face any rebellion situation. On the request of President Bashar the Lebanese Hezbollah joined the government forces to fight against the rebel groups in the country. Hezbollah is the close ally of President Bashar al-Assad and this is giving full support to assist the President in crushing the hated protest against him in Syria. In this fight, Hezbollah group have killed more than 70,000 people in Syria. Hezbollah is securing President Bashar regime like a strong wall in the country on the request of Iran. The intervention of Hezbollah in Syria has complicated the situation of Syria more intensively. One of the most important protester leaders Ahmad al-Assir has called his supporter to face Hezbollah group with full power and let them taste the sand in the fight. On his call many volunteer rebels have made them prepar e to fight against Hezbollah to the last drop of their blood. The fight between Hezbollah and rebellion groups of Syria has increased the tense situation of the country. A worst war has been out broken just because of the natural hatred against Hezbollah in the mind and heart of the people of Syria. This fight of Hezbollah and the rebellion groups had been resulted in a great massacre in Syria. A large numbers of people have died from both sides in this conflict. The situation is getting worse as time passes. The full support of President Bashar to Hezbollah has made the protester angrier and the wave of fight, protest and hatred against President Bashar has grown worse and the enmity has reached to the peak. (http://www.huffingtonpost.com/2013/04/26/hezbollah-syria-war_n_3160447.html?utm_hp_ref=world) Jabaht Al-Nusra Group: Jabaht Al-Nusra has risen as a most opposing group against President Bashar regime. This group is the major fighting force in Syria. This group is fully equipped with fully trained and ready to die fighters and the numbers of fighters in this group are increasing. Jabaht Al-Nusra has one more important characteristic of having a vast and strong network bounding relationships with other Islamic groups like Al-Tawhid, Liwa Al-Ummah, Ahrar Al-Sham, Suqur Al-Sham and Jund-Alsham. The altogether numbers of fighters in these groups are around 40,000; most of them are actually the local Syrian people who joined this group just because of getting annoyed by the policies and harsh treatment of President Bashar against his own countrymen. Jabaht Al-Nusra is in the front line of opposition against President Bashar, which are opposing Bashers regime by using weapons. Recent news has confirmed that Jabaht Al-Nusra has links with the terrorist group Al-Qaida. According to BBC News, Al-Qaida for th e very first time has announced the Jabaht Al-Nusra group as a part of its network that are fighting in Syria. The leader of Al-Qaida Abu Bakr al Baghdadi has said that the Jabaht Al-Nusra group is fighting in Syria for the establishment of an Islamic state in Syria. This declaration is made in an audio message in which the suspicious links of these two groups has been confirmed by Abu Bakr al Baghdadi, head of Islamic State in Iraq. This group has claimed to be an influential power behind a numbers of suicide bombing attacks in Syria at the time of uprising which started in Syria in March 2011. The United Nation has declared this Islamic group Jabaht Al-Nusra as a blacklist terrorist organization because of its brutal and merciless suicide bombing attacks in Syria and increasing the conflict situation in the country. (http://www.bbc.co.uk/news/world-middle-east-22078022) 2.2 Impact of External Lobby: United States Of America: The United States of America has raised its voice against the brutal killings of civilians in Syria but has no plan to intervene in the country currently. In Syria the dictatorship is so strong that United State has no control over this Arab regime. In the start of this uprising the position of United States was vague regarding the situation of Syrian regime. It was not clear that if the United States wanted the regime to fall or sustain. The Syrian regime is providing a secure border to Israel. United States always wanted to secure Israel and in the current regime of Assad the borders of Israel are more secure. The current regime of Syria is very clear and straightforward regarding Palestinian organizations in Syria; according to current regime the Palestinian organizations and fighters groups are banned to plan or execute their martial operations against Israel from Syrian land. United States is well aware that the next regime in Syria will not give as strong border to Israel like the current regime is providing. The down fall of the current regime may bring weaker borders of Syria with Israel and the exile groups of militants from Iraq, Libya and Palestinian fighter may have an uninterrupted entrance in Israel. Thats why the intentions of U.S. for Syria are sceptical. In the past few months the news of chemical arms used by Bashar have been exposed by the media and now the U.S. are showing more concern in the situation of Syria. US President Barrack Obama has promised to conduct a vigorous investigation about the use of chemical weapons by Syrian forces and warned the Syrian regime that this act of theirs can be a turning point of the relationship of US with Syria. He furthermore said that not only US but all around the world have to recognize and need to stand against the use of chemical weapon on civilian populations. (https://now.mmedia.me/lb/en/nowsyrialatestnews/obama-vows-vigorous-probe-into-syria-chemical-arms-claims) Iran Iran is the strongest ally of President Basher and his government since the time of uprising started in the country. Iran has the concept that all the riots and protest in the Syria are held on the signals of America. All the protests are pro-American and these riots have nothing to do with the benefits of Middle East. Iran is assisting President Bashar with its army and artillery to crush down the revolution. The President Bashar and Iranian government has good relationships. The main reason of this good relationship is the same religious views between them. The Iranian government is following the Shiaism religion and the regime of Syria is also the followers of same religion. This similarity of religion has brought both the allies more close to each other. Iran is assisting President Bashar with all kinds of assistance. The army of Iran is currently present in Syria to fight with protesters and rebellion groups. A large number of people are killed by the Iranian soldiers in Syria. Syrian regime is relying on the loyalties of Iran and getting a massive support from the Iran. Iran considers the President Bashar a strong ally and if Bashar regime fails in Syria then it is considered that one wing of Iran will broke. For this purpose Iran is using all its resources to secure the regime of President Bashar. All the contacts of Iran are being used by the Iranian government to save President Bashar. The main contacts of Iran are from Iraq to Lebanon. Irans defence minister Ahmed Vahidi has announced publically that if Syrian regime could not succeeded in putting down the uprising then Iran would dispatched its military help to Syria after signing a mutual defence agreement between Iran and Syria. In the uprising of Syria the Iran is assisting President Bashar to keep his power to him through all possible means like, cash, military, weapons and fighters. (http://online.wsj.com/article/SB10000872396390444230504577615393756632230.html) Turkey In the beginning of uprising in the Syria the Turkey was concerned to keep its relation with the regime of the Syria. Initially Turkey did not say anything openly in favor of opponents of President Bashar. Turkey started to rethink over its stance on Syria by the summer of 2011 when a large number of civilians were killed brutally in Hama and Latakia by Syrian army. In August, the foreign minister of Turkey Ahmet Davutoglu arranged a meeting with President Assad that continues for six hours. In this highly official meeting between two countries the Turkish foreign minister warned President Assad that if the killing of civilian did not stop immediately then Turkey will stop dialogue with Syria. In June the next month of this meeting, the patronage NGOs of Turkey started gathering Syrian opposition groups in Istanbul after the approval and consent of Turkish government. The participants of this gathering were not interested to discuss on titles like Change for Syria or National Freedom Conference, rather they demanded that President Assad and his supporter first step down from the government and then discussion about new Syria will started with them. The Syrian National Council (SNC) came into existence in Istanbul and it represented itself as a main political address party for opposition. Turkey unlocked its borders for the Syrian rebel groups. In July 2011, a large numbers of retired Syrian army soldiers reached in Syria under the leadership of retired air force colonel Riyad al-Assad. These groups of retired soldiers made an organization in Turkey named Free Syrian Army. The main objective of this organization was to work hand in hand to get freedom from President Assads cruel government. This organization proved itself as an umbrella organization and strongly opposed the concept of table talk with President Bashar regime. In September 2011, Turkey has decided to finish all the contacts and relationships with Syrian regime and imposed army restriction on its s outh border. The good relationship between two countries has come to an end and Turkey has announced the Syrian National Council (SNC) as an official representative of the Syrian Opposition. http://www.merip.org/mero/mero012813

Macbeth Character Flaw :: essays research papers

Brian Bozarth  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Bozarth 1 Mrs. Thurmond English IV – 6 February 22, 2001 Macbeth’s Tragic Flaw   Ã‚  Ã‚  Ã‚  Ã‚  Every one has a character flaw. Some are more serious than others. For instance, some people pick their nose, while others drink milk directly from the carton. After a while a person’s character flaws will come back to haunt them. Shakespeare is a master at pointing out one’s character flaws and showing how those flaw bring down that person or society in general. In Shakespeare’s Macbeth he does just that. Macbeth is a tragic hero whose character flaws are ambition and avarice.   Ã‚  Ã‚  Ã‚  Ã‚  The play opens with Macbeth, a popular noble who quells a military coup against the King of Scotland by a Scottish nobleman, Macdonwald. This is looked at by other nobles as and honorable deed. The King then gives Macbeth the late Macdonwald’s former title. In this instance ambition is a good thing: but alls to week for brave Macbeth – well he deserves that name (I ii 16). The king even said â€Å"O valiant cousin! Worthy gentleman†(I ii 24). His ambition was use to do a good thing, but if you stop to think; would any of this happened had he not killed Macdonwald.   Ã‚  Ã‚  Ã‚  Ã‚  In the next scene we see the witches doing things that witches like to do. Then enters Macbeth with Banquo. They spot the witches and Banquo insults them. The witches turn to Macbeth and tell him he will be king: All hail, Macbeth, that shalt be king hereafter (I iii 50). That single line is what sparks Maspeth’s evil ambition. This is the also the point when Macbeth start to turn evil. The witches also tell Macbeth he will become Thane of Cawdor. Macbeth replies to all this: to be king stands not within the prospect of belief (I iii 75). At this point Macbeth is skeptical, but then Ross tells him he is thane of Cawdor. Macbeth starts to believe he can become king. He is now successor to the throne of Scotland.   Ã‚  Ã‚  Ã‚  Ã‚  Since Macbeth is heir to the throne of Scotland, all he has to do is get rid of King Duncan. In scene IV Duncan names his son the Prince of Cumberland. Macbeth is outraged:   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The Prince of Cumberland! That is a step   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  On which I must fall down, or else o’erlap,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  For in my way it lies. Stars, hide your fires;   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Let not light se my black and deep desires:   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The eye wink at the hand; yet let that be

Evaluation to organisational learning practices

Organisation make decisions which are routine, daily in nature, operational or strategic in nature; which has to do with the corporate or organisational plan on how to operate and carry out its function in order to effectively and efficiently attain its objectives and goals. These decisions sometimes result in consequences that are not favourable to the organisation. Sometimes the organisation stands to pay dearly for embarking on the wrong decision, or making a nice decision at the wrong time.Thus, organisational learning is a way out and a field, which contemporary organisations have adopted in learning to detect and make corrections to erroneous decisions in the operational strategy of the organisation. The context and content of the organisation’s operations are studied; the vicissitude associated with it is taking into cognisance. And how this affects the organisational managerial functions of Planning, Organising, Staffing, co-ordinating, Reporting and Budgeting, is also studied so as to bring about effective and efficient decision making in the organisation.What role does evaluation play in the organisational learning practices? Since evaluation is a useful tool in the hands of managers of administration, it is seen that evaluation approaches set good record at providing accurate, valid and appropriate information in individual and the organisational successful decision making. Thus, the kernel of this write up is to peruse and critically analyse the contribution of evaluation to organisational learning practices. CONCEPTUALISATION OF TERMS What Is Organisational Learning?A prominent scholar that has contributed immensely in the field of organisational learning is Prof. Chris Argyris. He has to his credit several books on organisational learning. And also the works of Don Schon is highly recognised. Learning accordion to Argyris and Schon (1978:2), involves the detection and correction of error. Organisational learning concerns on how organisation s learn to be positioned effectively in detecting and making correction to unfavourable decision and organisational strategy.The rapid changing environment that most organisations assume had made the acquisition of new knowledge difficult and problematic. â€Å"Even if change is endemic this is questionable. As well as being proactive or simply passive, organisations may also be victims of excessive change† (Mande, 2005). As a way of carrying out organisational learning, Argyris and Schon (1974), came up with the Single-Loop Learning and Double-Loop Learning. In Single-Loop learning, given or chosen goals, values, plans and rules are operationalised rather than questioned.According to smith (2001), single-loop learning seems to be present when goals, values, frameworks and to a significant, extent strategies are taken for granted. In single-loop learning the underlying programme is not questioned; the overwhelming amount of learning done in an organisation is single-loop lear ning, since it is designed to identify and correct errors so that the job gets done and the action remains within stated policy, guidelines. (Argyris, 1993). Single-loop learning is described as a thermostat that learns when it is hot or too cold and turns the heat on or off.This is performed with the information received by the thermostat regarding the room temperature and take corrective measures. The Double-loop learning gives question to governing variables themselves, to subject them to critical scrutiny. Such learning may them lead to an alteration in the governing variables and, thus, a shift in the way in which strategies and consequences are framed. (Argyris and Schon, 1974). To Usher and Bryant (1989:87), â€Å"Double-loop learning involves questioning the role of framing and learning systems which underlie actual goals and strategies.Argyris (1974; 1982; 1990) argues that double –loop learning is necessary if practitioners and organisations are to make informed de cisions in rapidly changing and often uncertain contexts Edmondson and Moingeon (1990:160) puts it that; The underlying theory, supported by years of empirical research, is that the reasoning processes employed by individuals in organisations inhibit the exchange of relevant information in ways that make double-loop learning difficult and all but impossible in situations in which much is at stake. This create a dilemma as these are the very organisational situations in which double-loop learning is most needed.The diagram below illustrate and represent the process of organisational single and double-loop learning. Source: Mark K. smith 2001, Chris Argyris: Theories of action, double – loop learning and organisational learning. The diagram illustrates that consequences from the organisational decisions and strategies that are unfavourable under the single-loop learning, these are modified in line with organisation’s actions and strategy, but under the double-loop learni ng there is an over all change and revert to other governing variables that seem better and operationalisable in effective attainment of the organisational goal.What Is Evaluation ? In the process of making decisions about organisation practices and strategies many alternatives are forgone for a chosen one. And it become necessary to assess the chosen option so as to know if really it meets its target or in other words, if the choice for choosing it is not a wrong choice. In this same vain, Fadeyi (1999:74), has it that â€Å"Once appropriate alternatives have been isolated, the next step in decision making is to evaluate them and select the one that will best contribute to the goal.This is the point of ultimate decision making†. Evaluation, according to Williams (2005), is a field that accurately, validly, and rigorously explores the values or worth of human activities. The term is most commonly applied to the assessment of publicly funded social programs, but can cover just about any to include many elements which make it useful in decision making. However, to Oksanen (2005), â€Å"evaluation is not a magic cure for all situations; rather, the launch of an evaluation has to be well-planned and it must be based on clear goals.Evaluation is an assessment of set plan, decision or strategy of an organisation or individual, or a group etc, to see if they are able to effectively meet the target, objectives or goals to which they are drawn to meet. Thus, evaluation enables any organisation to know whether to modify and existing organisation an existing organisation plan or strategy, or to put it aside and choice another alternative, or better still to keep on adopting the same strategy and plan if there is no variance between its expected result and actual result.Though, sometimes evaluation has not successfully bring together individual and organisational decision making. As Williams (2005) puts it â€Å"Established evaluation approaches have a good recor d at providing accurate, valid and appropriate insights, but have had mixed success in getting these incorporated into individual and organisation decision making†. Nevertheless evaluation has been an effective tool in better decision making in organisation. METHODS OF EVALUATION According to Williams (2005), the methods of evaluation have been drawn from the applied social sciences.Interview, survey and small group processes have been the dominant data collection tool, written reports and oral presentation have been the dominant reporting tools. The inherent assumption that underpins most evaluates data leads to reliable information; and reliable information influences appropriate organisational and individual behaviour. In the view of Fadeyi (1999:74), two major methods of evaluation are; 1. Marginal Analysis: This is an evaluation system whereby the additional revenue and the additional costs are compared.This can be used where the objective is profit maximisation, which ma y require optimum use of machines that can be achieved when additional input equal output. 2. Cost Effectiveness Analysis: Cost effectiveness, in its simplest form, is a technique for choosing from among alternatives, by identify a preferred choice when objectives are far less specific than those expressed by such clear quantities as analysis does is to force the decision maker to see various alternatives, by identifying a preferred choice when objectives are far less specific than those expressed by such clear quantities as sales, costs or profits.All cost effectiveness analysis does is to force the decisions makers to see various alternative in light of their effectiveness versus their costs. CONTRIBUTION OF EVALUATION TO ORGANISATIONAL LEARNING PRACTICES. Evaluation, as discussed earlier, is an effective tool for decision making and choosing the right and feasible options among given alternative choices. Through it an organisation is able to receive an operating strategy for the organisation that would make it attain its objectives and goals, not only effectively, but also efficiently.Thus, evaluation plays a significant and key role in an organisational learning practice. Evaluation ahs a prominent role in the extensive organisations such as ministries and research institutes, evaluation practices has enhanced the capability of this organisation to make extensive reforms. Thus, institutional evaluation become more potent than research and development programme which is indirect and takes place within a longer time span â€Å"institutional evaluation, on the other hand is easier to detect compared to the potential effects that an R & D programme evaluation can have on the evaluated activity† (Oksanen 2005).Another contribution of evaluation to organisational learning practice is that it makes an organisation to be in a position to choose and make decision on the corrective measure to adopt on policy plans and organisation strategy that its consequenc es are not effective enough to meet the set goals and objectives. Hence, an organisation would be in a better position, after conducting its evaluation, whether to adopt the single-loop or double-loop learning method.â€Å"Evaluation information is seen to be closely intertwined with other relevant sources at the decision makers disposal†. (ibid. ) Here, evaluation makes the task of choosing he mode for organisational learning easy; since assessment would have being made to see what the organisation ahs done, and what it is suppose to do. This will place them in a better position to make better decision in this regard. Evaluation stands as a management tool that plays several functions in the organisation management and learning practices.According to Oksanen (2005), â€Å"a recurring view associated evaluation with cost awareness both at the level of an individual research organisation. Programme, and at the level of the national R & D. system as a whole† As a managem ent tool evaluation is not only seen as a tool of ensuring the accountability and relevance of development activity in an organisation, but also as a procedure closely linked with internal development and learning. Hence, evaluation is a tool to conscientise and makes organisation staff to reflect on what they do and the role they play in the organisation.As Oksanen (2005), put it, â€Å"evaluation process offered the staff an opportunity to pause for a moment and to reconsider what they are doing, why they are doing it, and how they are doing it†. This way evaluation brings out the week points of stays and through the organisation learning practice corrective measures are taken to strengthen and armed these lapses in the organisation. Closely related to the above point is that evaluation makes an organisation know its strengths and weaknesses. Thus giving it the opportunity to correct and strengthen its weaknesses.Illustrating this with ALNAP, annual review in 2001, with the aid of its evaluation reports, the report has it that, â€Å"it would appear that in some areas at least, co-ordination being a case in point, this year’s results are better †¦ this year’s sample provides a more positive picture than last year’s†¦ the ability of the ALNAP Annual Review series to highlight recurring problem areas within the Humanitarian Sector represents in itself a positive contribution†. (ALNAP Annual Review, 2003). Evaluation has helped the ALNAP organisation to know: ? Which organisations, and co-ordination bodies that are best placed to tackle the recurring problems.? If they consciously own the problem, i. e. are the issues being actively considered by key bodies within the sector. ? What progress is being made each year in the effort to tackle such problems (Ibid. ) Evaluation as a management tool, also stands to trigger a desired self-steering process in the organisation. Here, the organisation is made to be focus on tho se objectives and long term goals it seeks to achieve. And through evaluation in the organisation learning practices, the organisation is spurred and triggered towards the attainment of these targets and any observed variance is adequately taken care of.Also, evaluation helps to clarify the mutual expectations of partners and other interested parties. Outside the institution can turn out to be a learning process for a wider institutional environment, including agencies higher in the hierarchy, such as ministries and other partners† (Oksanen, 2005). Illustrating this, an evaluation of a research institute has offered the ministry concerned an opportunity to review the institute more thoroughly; its functioning, its position within the administrative field, and its role in the development of the sector in question.In addition, some interviewees at the ministry level felt that institutional evaluations have succeeded in pointing out weaknesses, which would demand internal changes even within ministries. (Ibid. ) In the view of Williams (2005) evaluation is germane in the arriving at a common ground for the diverging groups in an organisation. Evaluation approaches generally seek to get to the core issues, and as a result often explore ‘undiscussibles’ and raises issues that expose deep division within the community it is investigating. Evaluation stands as a tool for persuasion in the organisational learning practices.Here, evaluation offers general support of assurance in decision-making situation. Among decision – makers’ evaluation gives them a valued support in their decision-making. â€Å"Evaluation is seen as an important external ‘second opinion’, in relation to which decision-makers can reflect their own ideas. This ‘second opinion gives management the opportunity to assure itself that planned actions and strategic choices are also reasonable from an external point of view. â€Å"(Ibid. ). Evaluation i s valuable for justifying and convincing others about the necessity of proposed decisions.Within the organisation evaluation provides support tot he decision – makers in relation tot he staff. Here, the decision maker can not stand alone, but point out someone from the outside who has objectively assessed the situation and has arrived at a conclusion that such decision are inevitable to put aside. Evaluation also contributes to an organisational learning practice by positioning the organisation to have the willingness to improve on its observed results. When evaluation is carried out, if the result that the organisation gets is unfavourable, it tends to strive to improve upon this, so as to obtain a better result next time.To Udell and Baker (1977), cited in Sexton, et al (1989), advantages of innovative evaluation to inventors, when their innovation and ideas are subject to it, includes; 1. A general idea of a commercial viability of their new product idea. 2. Input concerni ng potential problems likely to be encountered during the innovation process. 3. Unbiased opinions from individuals who have the expertise to evaluate a new product ideas or invention. 4. Pertinent information that will be useful in presenting the concept to others 5. Direction regarding additional information needed for a more thorough evaluation of the product.6. Opportunity, based on the information provided, to make a more informed decision about whether to drop or proceed with the product. 7. Information that may help attracts investors. It is seen that these highlighted advantages of evaluation to innovative ideas are similar to those that an organisation derives when evaluation are linked up with the organisation learning practices. HINDRANCES TO ORGANISATION’S EVALUATION A major hindrance to effective evaluation is when the objectives and goals of an organisation are not clearly stated and straightforward and explicit.It makes the evaluation of such goals and objectiv e very difficult. This tends to hamper the results of the evaluation process. As the ALNAP annual review (2003) has it â€Å"The potential contribution of evaluation genres to learning is often hampered by a lack of clarity as to the purpose, the under-use of approaches and techniques likely to increase learning at the individual and team level and the under use of evaluation materials and case studies in training. According to Oksanen (2005), the most often mentioned weak points to evaluation includes:1. Lack of time for evaluations which may lead to inaccuracies and superficiality in results; 2. Evaluators’ competencies and in particular, their insufficient knowledge of local circumstances. CONCLUSION From the write-up it is seen that evaluation plays a significant role in organisational learning practices, through evaluation the learning practice is made feasible and effective. This make the decisional aspect of the organisational practice to be generally supported and ac cepted in the attainment of set goals and objectives for the organisation.Through evaluation, the organisation strengths and weaknesses are observed and corrective measures are better put in place to correct these weaknesses BIBLIOGRAPHY ALNAP Annual Review (2003), –Chapter Five.

The Process Of Modelling Erosion Environmental Sciences Essay

This papers is intended as a literature reappraisal of research on how to pattern the eroding. Erosion is a natural procedure that has become a serious environmental job due to the action of several natural and human factors. For case, deforestation, fires, unequal agricultural patterns or inordinate building of edifices and roads have skyrocketed this phenomenon. Erosion causes transit of deposits to rivers, swamps and lakes, increasing the hazard of deluging when raining. Besides, eroding reduces the capacity of dirts to hive away H2O, and do the loss of foods and organic affair worsening the biodiversity of the part. The engagement of the governments is needed to set up programs to command this phenomenon. 2 Definition of Erosion The word eroding, from Latin, means gnaw off ( Ghanshyam, 2009 ) . Erosion means the remotion of stuff from one topographic point of the Earth ‘s crust to the other by the impact of geological agents ( Krebs, 2003 ) . Erosion is a phenomenon that occurs at really slow rates. For illustration, Patric ( 1976 ) references some illustrations of a general rate of 0.18 to 0.30 dozenss / acre / twelvemonth. Obviously this rate will change depending on many variables on the surface of the Earth. Areas on the Earth surface that is more immune to erosion, such as forest land can supply rates of 0.05 to 0.10 ton / acre / twelvemonth. In contrast, countries with high rates of eroding such as agricultural land may stop up giving rates of 1 to 5 dozenss / acre / twelvemonth. Erosion is a natural procedure linked to the kineticss development of the planet and is a measure within the geological rhythm of the Earth ‘s crust. The geological rhythm which includes eroding is intended to accomplish a mass balance between the highest countries of the planet and the lower countries ( Khan, 2006 ) .3 Erosion within the Geological rhythmThe Earth ‘s crust is subjected to a uninterrupted transmutation ensuing from the action of geological agents, both internal and external, which are the elements that model the Earth surface ( Ramberg, 2008 ) . The Internal geological procedures have their chief beginning in the internal heat of the planet, and they are constructive, they are responsible for the formation of the Earth surface. These geological procedures appear in signifier of slow motions ( orogenic ) or sudden events ( temblors and vents ) , which give manner to the formation of new minerals and stones. External geological procedures are caused by the action of external agents ( air, H2O, air current, snow ) .3.1 Weathering, conveyance and depositWeathering is the procedure of break and decomposition of stones by the action of external agents. Weathering occurs in the topographic point where the stones are, without being transported. When the decomposition takes topographic point in combination with conveyance so is called eroding ( Gifford, 2005 ) . Weathering may be chiefly mechanical ( physical ) or chemical, but in most occasions operate combined. The conditions will be a cardinal factor in the laterality of mechanical or chemical weathering. Mechanical weathering is the physical decomposition of stones due to events such as dilation and alterations in H2O temperature ( Gifford, 2005 ) . This instance is common in hot dry climes where the uninterrupted alterations of temperature contribute to do snap and break in the stones. In cold climes, the H2O freezes in clefts perforating moving as a cuneus, doing the break and atomization of stones. Chemical weathering is the change of the mineral components of stones by the action of atmospheric gases ( O, C dioxide ) and H2O ( Gifford, 2005 ) , which performs procedures such as hydrolysis and hydration. Transport occurs on weather-beaten stuffs, fragmented or dissolved which can be eroded and moved from their topographic point of beginning, by the action of gravitation, which will take them from high to low countries. The chief conveyance agents are H2O overflow ( watercourses, rivers ) , ice ( glaciers ) , air current and sea ( coastal countries ) ( Ghanshyam, 2009 ) . The deposition of the eroded and transported stuff ( fragments of stones, dead beings and chemicals ) consequences in their deposit when it stops the consequence of gravitation and make more stable topographic points. The zones of accretion of deposits are sedimentary basins, which may be inland ( a lake or a river vale ) and ocean, deep sea, which are the most of import. In the instance of comeuppances, deposit occurs when the consequence of air current Michigans.3.2 Wind erodingWind eroding occurs in desert parts ( dry conditions ) , where rainfall and flora are scarce, with a preponderantly mechanical weathering. Wind eroding depends on many factors: conditions forms, dirt conditions, and flora screen ( Shao, and Leslie, 1997 ) . The deposition of stuffs occurs when the air current velocity lessening, ensuing the dunes, which are accretions of sand, which besides appear in coastal countries, as seen in some beaches.3.3 Water erodingSurface H2O ( overflow ) is the chief conveyance agent of alleviation modeling in the Earth ‘s surface. The behavior of surface H2O depends on their speed, which is relative to the incline. The greater is the speed larger the eroding consequence. Therefore, a graduation of the features of surface H2O can be seen from the topographic point of beginning until deposition occurs of the stuffs transported.3.4 Ice erodingGlaciers are accretions of ice, being located in the polar caps and in cragged countries. They originate in topographic points where rainfall is in the signifier of snow, which does non run and accumulates, until it becomes compacted and hardened into ice. The erosive glaciers can be of great importance in some countries of the Earth. In some countries of the planet can go the chief agent eroded go forthing a characteristic landscape. Glacial eroding occurs when immense multitudes of ice traveling easy through gravitation. This phenomenon carries the stuff in its way that act as an scratchy, crunching and smoothing the rock bed on which it travels.3.5 Coastal erodingGeological action of sea H2O plays an of import function in coastal modeling. The eroding occurs when moving ridges impact the stone. The accrued energy of the moving ridges crashing against the drops causes its gradual dislocation. Erosion rate depends on the petrology of the seashore and the moving ridge energy. Materials are so transported by moving ridges and currents and deposited in the signifier of pebbles, crushed rock and sand at the pes of the drop. Lighter atoms are deposited on the ocean floor.3.6 Human erodingHuman activities contribute in a meaningful manner t o the eroding of the dirt, including large-scale agribusiness patterns.Factors that determine the erodingAmong the most of import factors that have a major influence on the control of the eroding is without uncertainty the clime. There are several variables which can be derived from climate, including the most of import, the rain. The kinetic energy of raindrops when they hit the land cause the decomposition of the stuffs and therefore the eroding occurs.
