Vmware (virtual servers) - Assignment Example Question 25: The best disaster recovery for VMware is by making use of back-up process on the servers and replication of virtual machines in the network. This can be best deployed using storage where NAS is deployed for VMs and Servers in the network (Muller 123). Question 26: vMotion works by encapsulating VMs on shared storage and then the enclustered VMs allow multiple installations on an ESX server. The memory and execution state of the VMs is transferred to high speed network. This is done by copying memory and system states of the ESX server. To allow identity of the VMs, networks used by the VMs are also virtualized by the ESX server (Wolf 84). This transfer (vMotion) takes very few seconds. Question 27: A snapshot presents a complete copy of a virtual machine at any time and all the changes made. While a clone is the exact copy of the virtual machine during the cloning process. Any changes made on the parent of the clone are not reflected in the clone. Therefore using snapshots provide better functionality than clones. Question 28: Fault Tolerance in VMware works through the use of a technique known as Record/Reply. This technique provides continuous availability to the virtual machine in case the host fails. This works whereby if a VM goes down it is restarted in another host and the secondary host now becomes the primary host while a secondary host is being looked for (Muller

WSJ Analysis Number 3 Essay Example | Topics and Well Written Essays - 500 words

WSJ Analysis Number 3 - Essay Example Yamahas position is that of saying that the other side would, â€Å"have seized on safety and product enhancements that Yamaha has made to the Rhino to allege baseless claims about the stability of the vehicles,† (Conkey & Trottman, 11/04/08). Like other vehicles of the sort, the Rhino, according to Yamaha, was designed to go in the areas in which are considered to be all terrain and handle such things as what can be hazardous environmental conditions. Yamaha further maintains its claim that it has done everything within its power to maintain a complete level of maintenance on its products. Legislation as of August 2008 would make it possible for those standards that would have been voluntary beforehand, to be more required as a result. Further stating that they cannot respond to claims that have not been brought forth with any proof as of yet, Yamaha insists upon the standard business claim of truly caring about each and every customer. As for relevance to the marketing issue, any form of discrepancy as it comes to the safety of a product or service that a company may provide, can result in a great deal of problems for the companys economic future and the image which they bode with both their customer base as well as federal regulators. This sort of concern in regards to the issues of product safety can prove to be very fatal to the overall stability of the company itself. With the current economic status of the nation being tenuous at best, any sort of doubt in corporate integrity and that which they produce for the public, can only prove to be more disconcerting to a market already stressed from economic uncertainty of the present day. As has been in the case in other circumstances, it is often times very common for a company to fight off such allegations made in the hopes of saving the reputation that they have. In some cases to settle when

The root causes of the Turmoil in the Middle East Research Paper

The root causes of the Turmoil in the Middle East - Research Paper Example 4). It is generally conceded, however, that the countries that comprise the Middle East include Algeria, Bahrain, Egypt, Israel, Lebanon, Iran, Iraq, Syria, Kuwait, Morocco, Oman, Palestine, Qatar, Libya, Sudan, Syria, Tunisia, Turkey, the United Arab Emirates, Yemen, and Saudi Arabia (Middle East Information Network, 2010). From as far back as history records, the Middle East region has been beset by armed unrest and turmoil, of every possible kind – between the Arabs and Israelis on territory, between two or more Arab nations on borders, between Arab nations based on alliances in the Cold War, and even within Arab nations in the form of interracial or ethnic conflicts. More recently, civil social unrest against autocratic regimes, similar to those in eighteenth century Europe, ushered in a different type of turmoil that expressed the popular desire for democratic reforms. This study shall briefly discuss the principal causes of turmoil in the Middle East, namely: (1) the int erests vested by the Western superpowers in the region; (2) the contest for territorial control and misspecification of boundaries, and (3) the clamour for democratic governance and the end of kleptocracy and autocracy. Interest of superpowers in trade access and oil reserves The geographical location of the Middle East played an important role in the origin and progress of turmoil in the region. ... Even in contemporary times, its strategic location has sparked occasional military offensives, such as that mounted by Israel against Egypt when the latter denied access to Israeli shipping through the Suez Canal (Milton-Edwards & Hinchcliffe, 2008). Besides being the trade gateway to three continents, the region is also situated over the world’s largest oil reserves, representing roughly two-thirds of all the oil supply internationally. Over 60% of the proven oil reserves in the world is to be found in the Persian Gulf, for which stakes the world’s superpowers had played for. This has been the principal interest of the U.S. and the USSR in the region during the Cold War. Other factors such as the U.S.-Israeli alliance precipitated the USSR-Afghanistan tie-up in the post-World War II power alignment, which served to establish their bid for control of the region’s oil (Heini, 1970). One may argue that the world’s superpowers have interests around the globe at one time or another, but despite interventions from the major developed countries, this fact does not necessarily lead to the continuous state of turmoil or unrest that is evident in the Middle East. Thus while it is an important external cause, it is one that impacts most those countries that are weak or unstable. Contestation of territorial control and illogical boundaries Many point to the Israeli-Arab war as a religious war; in truth, it is more a territorial war. The seeds of conflict were sown in 1947, when Britain withdrew from Palestine and a U.N. resolution called for the partition of Palestine into two, a Jewish state and an Arab state. Resistance to this partition erupted into hostilities between

2000 word - subject PDAS301 - People, Organisations and Adminisration - Essay Example S. Pugh, as â€Å"the study of structure functioning and performance of organisations and of the behavior of groups and individuals working in them† (Murugan). These principles provide significant purpose to managers and members of such organizations as well as students of management, business and sociology courses. These principles are moreover, broadly categorised into the classical approach, the neo-classical approach, the modern approach and the post-modern approach. The distinctions among these different approaches lie on the primary focus with which they give importance to. In the classical approach, for example, what is given significant importance are the technical aspects of organizations like formal structures, management, and principles of organisation. Theorists belonging to this approach are Frederick Taylor, Henri Fayol, and Max Weber. The neo-classical approach, on the other hand, gives emphasis on the human aspects of organisations like motivations, behavior and conduct of people involved in the organization. Some of the theorists in this approach are Elton Mayo, Abraham Maslow, Mary Parker Follett and Douglas McGregor. The modern approach, on the other hand, combines the best of both classical and neo-classical approaches by giving emphasis both on the form and structures of organizations and the human factor. Researchers and writers who patterned their research along this model are Chester Barnard, Herbert Simon, and Amatai Etzoini . Finally, the post-modern approach, the least rigid and the most flexible, does not subscribe to any particular form or rule of organizations but stresses that organizations should adapt to internal and external factors surrounding them. Post-modernist theorists are Tom Greenfield, Tom Sergiovanni and Gareth Morgan, among others (Mullins 1999). This paper will examine four theorists representing each of the different organization and management approaches: Max Weber, of the classical approach, and

Research methods Assignment Example | Topics and Well Written Essays - 2000 words

Research methods - Assignment Example One of the major sources that can lead to invalidity and unreliability in a research is the bias of the researcher (Baumgarten 2012). Biases in research are mainly categorized into selection bias, measurement bias, and analysis bias (CEMÂ  - Research -Â  Bias & Confounding n.d.). The present study focuses on learning about the different types on bias in research studies with specific examples for each of the types. Bias and Types of Bias in Research Studies: Bias is said to have occurred in a research when the outcomes of the research are different from the actual results. For example, if a research is focused on determining the risk of a disease and the results of the research reflect consistent overestimation of the risks, then the study can be said to have been based on bias. Design of a research is largely responsible for a bias and bias in general presents error in the same direction for a repeated number of the experiments for a particular research sample and work (World Heal th Organization 2001). Thus biases need to be reduced in order to produce a reliable and valid research. Types of Bias with Examples: Selection Bias: Selection bias is defined as the bias when some participants are favored and selected over others while sampling is conducted and the research outcomes are based on experiments conducted on such samples, thereby affecting the external validity of the research (Gravetter and Forzano 2010). It is also referred to as sampling bias. As a result of such bias, the outcome of the research reflects a systematic difference between those subjects that are included and those that are not. Thus either the results are underestimated or overestimated in terms of their statistics, rates, and ratios (Peat, Mellis and Williams 2002). This means that the study cannot be considered as reliable for use. Moreover, with different outcomes than the actual results, the validity of the research also gets reduced. An example of selection bias in research is a c omparison of patients in one hospital where a new wound dressing method is applied on them, with patients of another hospital who are offered the standard method of treatment. In such a case the possibility of selection bias is significantly high since different patients in different hospitals differ in their social and biological characteristics. Thus such a research is exposed to selection bias (Stommel and Wills 2004). Allocation bias is a type of selection bias that occurs when there is a difference in the characteristics of the different samples put in different trial groups of a particular research experiment, and has significant influence on the outcomes of the research (Peat, Mellis and Williams 2002). Measurement Bias: Measurement bias is defined as the bias that occurs when biases or errors occur in the process of measurement and calculations of the data based on which the results are obtained. Such biases can result from erroneous tools of measurement, errors in calculati ons, errors while measurements are recorded, participant bias, recall bias, and so on (Howlett, Rogo and Shelton 2013). For example, if dietary recalls are considered for a 24 hours time period, then measurement biases can occur with the methods of the interview, the assumptions of coding, or

Acid Rain in China Essay Example | Topics and Well Written Essays - 3000 words

Acid Rain in China - Essay Example The report further points out the ways in which production or business activities affect the natural environment. Additionally, it focuses on â€Å"Green Marketing† as an Environmental Management tool that business companies in China should apply in order to reduce the negative effects of acid rain on the environment. Kahn & Yardley report that pollution problem in China has shattered all precedents the same way the scale and speed of her rise as an economic power lacks a clear parallel in history. Environmental degradation in China is now so severe with such stark repercussions domestically and internationally. They cite the Ministry of Health in China having said that public health is reeling and pollution has made cancer the leading death cause in China – they attribute hundreds of thousands of deaths that China experience each year to ambient air pollution alone. They also give a report that often, Chinese cities appear wrapped in a toxic gray shroud with only one percent of her five hundred and sixty million city dwellers breathing air that the European Union considers safe. Environmental wretchedness that some countries might consider catastrophic can seem ordinary in China including industrial cities where people seldom see the sun; children sickened or killed by local pollution forms such as lead poisoning or an algal red tides-swamped coastline that large ocean sections no longer sustain marine life. According to Kahn & Yardley, China is choking on its own accomplishment and although her economy is posting double-digit growth rates succession, the growth derives from a wobbling expansion of heavy urbanization and industry, which requires massive energy inputs, of which it obtains almost all from coal, which is the most readily available and dirtiest source. Acid rain involves the acidification of rain by airborne acids.
