Someone Knows My Name by Lawrence Hill Free Essay Example, 750 words

ï » ¿Someone Knows My Name by Lawrence Hill Racial inequality has been one of the most discussed topics in the American society for years. Thanks to successes of the U. S. abolitionist movement in the 19th century and African-American Civil Rights Movement in 1950-1960s, the racial issue got gradually resolved. Formally, inequality segregation ceased to exist in 1960s. Yet, the echo of discriminative racial policies of the past is still heard today. Strong anti-slavery and anti-discrimination themes of the historical novel Someone Knows My Name by Lawrence Hill relate to the existing racial controversy in the American society today discussed by Desmond S. King and Rogers M. Smith in the article â€Å"On Race, the Silence Is Bipartisan†. In Someone Knows My Name, the problem of racial discrimination and inequality is highlighted through the lens of Aminata Diallo, a former slave who got liberated by the British during the War for Independence. Diallo’s enlightening account that dates back to the early 1800s takes readers to the time of the African slave trade known for its brutality and abysmal conditions. We will write a custom essay sample on Someone Knows My Name by Lawrence Hill or any topic specifically for you Only $17.96 $11.86/pageorder now Her message is no matter what race you are or what you eat, you share the same unique thing known as human nature. Given this, savagery and violence that filled the life of enslaved African-Americans need to be eradicated and should be never practiced again. To illustrate, Diallo’s thoughts of the black people’s powerless position due to the racial inequality policies are enhanced by an episode from her past: I was walking one day behind a yoked man who swerved without warning to the left. I had no time to react, and my foot sank into something wet and soft. Something like a twig cracked under my heel. I let out a scream. Under my foot was the body of a naked, decomposing man. I jumped away and ripped leaves from the nearest branch. In a frenzy, I wiped a mass of wriggling white worms from my ankle. I was shaking and wheezing. Fanta took the leaves and wiped my foot and held me and told me not to be afraid. But my hysteria escalated, even though Fanta barked at me to calm down, and I could not stop screaming. (Hill 41). The theme of racial inequality has been the focal message of â€Å"On Race, the Silence Is Bipartisan† by Desmond S. King and Rogers M. Smith. Specifically, the economic aspect of racial inequality has been discussed. The professors challenge the generally held view that racial issues have already been resolved and speak of the existing economic inequality between white and black, as well as Latino population in the United States. For instance, it is said that â€Å"in 2009, 35 percent of black households and 31 percent of Latino households had zero or negative wealth, compared with 15 percent of white households. † (King and Smith 1). The authors believe that this striking difference can be explained by the lack of â€Å"compromise policies† that address the needs of non-whites above all (King and Smith 2). Discussing the thematic connection between the mentioned works, one should mention the racial inequality point. Yet, the latter is represented differently. Hill’s account of racial discrimination at the end of 18th century unveils harsh violation of black people’s civil rights in each sphere of everyday life, while The New York Times article reveals economic differences between two racial groups that is interpreted as a manifestation of racial inequality. To illustrate, in Diallo’s time African Americans were perceived rather as animals, not human beings, and treated accordingly. On the contrary, â€Å"in a country where an African-American is the president† professors King and Smith identify the violation of economic rights in the first place (King and Smith 1). In other words, racial discrimination in the modern American society can be found in the figures of statistical estimates that explore the economic status of every social group, not in open vio lations of black people’s human rights. To conclude, things described in Lawrence Hill’s novel Someone Knows My Name connect to the events in the American society today through the racial inequality point. At the same time, the points discussed in the two works appear more different than alike: Hill’s description of black people’s powerless position focuses on the open violations of their human and civil rights, while King and Smith identify a lower economic status of the black population in general.

Conflict between Soft Skills &Technical Skills-Myassignmenthelp.com

Question: Discuss about the article Whose skill is it anyway? Soft skills and polarization written by Irena Grugulis and Steven Vincent (Grugulis and Vincent 2009). Answer: Introduction: The following report has concentrated on an article called Whose skill is it anyway? Soft skills and polarization written by Irena Grugulis and Steven Vincent (Grugulis and Vincent 2009). Different aspects of the article have been discussed in this report. Analysis: Focus: In the article Whose skill is it anyway? Soft skills and polarization, the writers have mainly concentrated on the skills that employers are looking for while recruiting employees in the organization. It has focused on the large business organization and analysed the recruitment process of the organization. It has mainly discussed about two basic skills on which employers focus, soft skills and technical skills (Grugulis and Vincent 2009). Problem: The main issue that has been discussed in the previously mentioned article is the preference of the recruiters is shifting from the soft skills to technical skills. According to the writers of the article, in recent time recruiters of the business organizations focuses more on the technical skills instead of the soft skills. The researchers have concentrated on exploring the reasons behind such practices (Grugulis and Vincent 2009). Key Ideas and Arguments: As per the article, in recent time, the employers concentrate on the technical skills of the employees while appointing them in any post. It helps skilled and talented employees to be appreciated by the authority. The writers claim that such practices mainly occur in the public sector. The competitive nature of the market has been increased drastically in past few years. It has led the organizational leaders to appoint some skilled and talented employees who have technical idea in the respective field. According to the report, the change in the nature of skill is the main reason for such practices. The report claims that, now a days skills include the capacity of team work, motivational power, judgement, leadership capabilities and so on. It has motivated employers to look for such employees that can stimulate the organizational performance by their technical skills. The report claims that there are some key issues with the soft skills, as it may influences discrimination in the work place. The writers have resented some examples of such workplaces where such discrimination occurs, such as- in call centres male employees are expected to meet their sales target whereas female employees are expected to perform in a significant manner. The study has provided some examples of renowned and large business organizations where soft skills are emphasised. The article has tended to distinguish between the soft skills and technical skills (Grugulis and Vincent 2009). Issues: Issues that must be enlightened from the study is that soft skills are mainly used in the case of women. They are allotted such tasks or such sections that suit their skills. However, the study has highlighted that it cannot enhance their position or reputation in the workplace. It will always distinguish them from other workers. Conclusion: As per the discussion, it can be concluded that there is a conflict between soft skills and technical skills. Employers are now a days looking for technical skills instead of soft skills as it will be beneficial for the future of their organization. References: Grugulis, I. and Vincent, S., 2009.

TCP/IP and OSI Networking Essay Example

TCP/IP and OSI Networking Essay In this essay I intend to analyse why networking software is divided into layers, and to evaluate the advantages and disadvantages of such a division. I will then go on to analyse what the main differences between the networking protocols known as OSI and TCP/IP are. I will also attempt to analyse what factors led to their successes and failures respectively in terms of their diffusion into the technology sector. However, before we can discuss this, we must first be sure that we are aware of the meanings of terms such as networks, network architecture, protocols, and distributed networks/systems so I will begin by defining these phrases. Essentially, a network is the connection of two or more computers for the purpose of data communication and resource sharing. the formal definition of a network could be given as a number of interconnected devices capable of communicating and sharing each others resources (Bandyo-padhyway, 2000:157) As can be seen from the above quote, networking offers organisations a wealth of benefits. A network enables an organization to centralize its computer system and allows users to access the facilities of a large computer system via desktop computers. (Bandyo-padhyway, 2000:157) It could be said that network architecture is, in theory, a model for the set-up of a network. To help deal with this complexity, network designers have developed general blueprints usually called a network architecture that guide the design and implementation of networks.

A protocol is a set of rules or conventions which govern the way a message is transmitted from the sender to the receiver passing through a number of steps and via a number of network elements. (Bandyo-padhyway, 2000:178) Finally, a distributed network/system is where the tasks to be to be performed are distributed among a number of small PCs that are coordinated by a larger central computer. (Bandyo-padhyway, 2000:173) Having defined the aforementioned basic technological terms, I can now go on to my analysis of the reasons why networking software is divided into layers. The primary reason is that having separate distinctive layers reduces design complexity. By this, I mean having different layers means certain operations and tasks that must be carried out, can be carried out in a simple and organised order, rather than all at the same time. First, it decomposes the problem of building a network into more manageable components. (Peterson Davie, 1996:30) Layering allows for changes to be made at a specific layer, as a result of new ideas/innovation, and will not disrupt the software at other levels. Second, it provides a more modular design. If you decide that you want to add some new service, you may only need to modify the functionality at one layer, re-using the functions provided at all the other layers. (Peterson Davie, 1996:30) This means that it accommodates incremental changes more readily. (www. cs. wpi. edu/~rek/Undergrad_Nets/B03/HTTP_DNS. pdf) Another advantage of layering is that details of how the lower level services are implemented are shielded from the higher levels, allowing the higher levels to function more efficiently. This can be seen, from a more technological point of view, in the following quote. Many times there are multiple abstractions provided at any given level of the system, each providing a different service to the higher layers but building on the same low-level abstractions. (Peterson Davie, 1996:30) A final advantage of layering is that as a result of the different types of layers, making it so different types of translations can take place; different types of hardware are enabled to communicate. Having looked at the advantages of layering, I will now spend some time discussing its disadvantages. Some functions (like FDDI station management) really need to access and operate at multiple layers. (courses. cs. vt. edu/~cs5516/spring03/ slides/introduction_6. pdf) As the above quote displays, one disadvantage is since the software is split up into layers, functions will operate at one level at a time, where as some functions have the necessity to operate at several layers. Poorly conceived layers can lead to awkward and complex interfaces. (courses. cs. vt. edu/~cs5516/spring03/ slides/introduction_6. pdf) This quote shows us that unless a large amount of thought and work goes into each individual layer, then a very bad and hard-to-use interface can be the end-result. Another disadvantage is if new design for a layer is done, an old layer may become inappropriate or unsuitable given the properties of the new layer. (courses. cs. vt. edu/~cs5516/spring03/ slides/introduction_6. pdf) A final disadvantage of layering is something known as information hiding, this may take place and this can lead to inefficient implementations. (www-inst. eecs. berkeley. edu/~cs268/ sp03/notes/Lecture2. pdf) I have discussed why networking software is divided into layers as well as evaluating both the advantages and disadvantages of layering. I now intend to introduce the first of the aforementioned protocols Open Systems Interconnection (OSI), before then introducing the second. A number of different types of distributed systems were being developed in the 1970s and as a result, a range of standards had to be introduced. (Halsall, 1996:11) An organisation called the International Standards Organizaton (ISO) created the ISO Reference Model for OSI. The ISO was a body founded in 1945 to coordinate international standards for a wide range of industries. (The Internet in the Arena of International Standards) Below is a diagram of the OSI protocol, taken from Peterson and Davie. As can be seen, the OSI protocol has seven layers. The application layer provides the user interface to a range of networkwide distributed information services. The presentation layer is associated with the representation of data during transfer between two communicating application processes. The session layers job is to set up a communication channel between two communicating application layer protocol entities during a network transaction. The network layer is responsible for establishing a networkwide connection between two transport layer protocol entities. The link layers job is to build on the physical connection provided by the network to provide the network layer with a reliable information transfer facility. Finally, the physical layer is associated with the physical and electrical interfaces between the user equipment and the network terminating equipment. (Halsall, 1996:16, 17, 18) I will now introduce the second networking protocol so that we have a good understanding of them both, before analysing their differences. The second protocol is called Transmission Control Protocol/Internet Protocol (TCP/IP). TCP/IP was developed by the US Department of Defence (DOD) research project to connect a number of different networks designed by different vendors into a network of networks. (www. yale. edu/pclt/COMM/TCPIP. HTM) The idea behind the DODs thinking was that in the Cold War, if the right designated place was bombed successfully, then the whole countries network communication facilities would become inoperable. This was obviously be a bad thing and so the DOD wanted to develop a standard that would connect all the networks together to prevent this from happening. Below is the model of the TCP/IP protocol, taken from (www-staff. t. uts. edu. au/~sean/DSP. dir/dsp00s. dir/lect1. dir/sld014. htm) As can be seen, the TCP/IP protocol has only four layers. The application layer handles high level protocols. The transport layer deals with quality-of-service issues. The internet layer determines the path to forward packets of data. The network layer is concerned with all of the issues that an IP packet requires to make a physical link. (www-staff. it. uts. edu. au/~sean/DSP. dir/dsp00s. dir/lect1. dir/sld014. htm) Now that I have briefly introduced both of the protocols, I will now move on to my analysis of their main differences. A difference between the two protocols in terms of their establishers is that OSI was orally established by Telcos, a telecommunications company and had a large connected emphasis linked to it. TCP/IP came more from a computing background with a large connectionless emphasis associated with it. Another difference that should be noted is that the two models have opposing approaches. The OSI model has a top-down approach meaning the processes that take place within the layers start at the top of the model and work their way down to the bottom. The TCP/IP model has a bottom-up approach meaning the processes taking place within the layers begin at the bottom of the model and move upwards. As can be seen from the models, the visible difference is the number of layers present within each. The OSI protocol has application, presentation, session, transport, network, data link, and physical layers. Where as the TCP/IP protocol has only application, transport, internet and network layers. Even though some of the layers have different names, they essentially do the same thing. However, the presentation and session layers that are in the OSI model are not present in the TCP/IP model. This makes the two protocols technologically different. First there were the technical differences, chief among them that OSI had a more complicated and compartmentalised design. (Lyon Hafner, 2003:246) The above quote points out how the OSI design was considered to be very large and complex where as the TCP/IP design was far more simplistic and smaller. On the OSI side stood an entrenched bureaucracy, with a strong we-know best attitude, patronizing and occasionally contemptuous. There was a certain attitude among certain parts of the OSI community whose message was, Time to toll up your toy academic network,' recalled one ardent TCP/IP devotee (Lyon Hafner, 2003:247) We can see from the above quote that OSI was regarded as a potential official standard with a considerable amount of bureaucratic support, as opposed to TCP/IP, which was seen by some as a toy network for the academic world only, and would never have any real chance of becoming an official standard networking protocol. The reason being was that the OSI was created by the ISO, and the ISO had long been responsible for creating international standards for a variety of industries, as the following quote displays. Since the 1940s, ISO had specified worldwide standards for things ranging from wine-tasting glasses to credit cards to photographic film to computers. (Lyon Hafner, 2003:246) As a result of this official standardization reputation that ISO had created for themselves, OSI was backed by several governments, led by Europe, and was thought to be meeting the needs of the whole world. Another difference between TCP/IP and OSI, was that TCP/IP had actually been implemented where as the only thing OSI had to offer was the design model for the protocol, as the following quote shows. And it was a design, never tried. As far as the Internet crowd was concerned, they had actually implemented TCP/IP several times over, whereas the OSI model had never been put to the test of daily use, and trial and error. (Lyon Hafner, 2003:247) An extremely large difference between the two protocols is in relation to their impacts on the networking world respectively. OSI failed to become to the official international networking standard that it was predicted to be. TCP/IP, contrary to what many had anticipated, was a huge success within the networking protocol world and is used across the world today. However, one must ask, what factors led to this outcome? One factor was that one key TCP/IP developer, Bill Joy, decided that TCP/IP when bought was to come with free networking software, which was based on Unix. As can be imagined, the fact that one received free Unix networking software when buying TCP/IP with no extra charge dramatically helped push TCP/IP further than OSI. The first Sun machines were shipped with the Berkeley version of Unix, complete with TCP/IP. Berkeley Unix with TCP/IP would be crucial to the growth of the Internet. When Sun included network software as part of every machine it sold and didnt charge separately for it, networking exploded. (Lyon Hafner, 2003:250) To clarify, Sun was the name of the computer company that Joy joined as the Unix expert. Another factor that led to TCP/IPs success was the fact that ARPANET decided to switch over to it on January 1, 1983. ARPANET was the resulting internetwork developed when computer networks associated with a large number of universities and other research establishments were linked and it was in large usage. (Halsall, 1996:19) As a result, TCP/IP was pushed even further ahead when ARPANET switched its protocols from Network Control Protocol to TCP/IP as this meant only machines running the new protocols could communicate over the network. Lyon Hafner, 2003:248) Dennis Jennings tells us of a factor that largely contributed to the failure of OSI when it was announced by the manager of a company called ICL at a review meeting that the output of the OSI research would not be in the interests of ICL. The Commission then told ICL that they could do what ever they like. This meant that where would be no available implementation opportunities for OSI once the research had been completed, and Jennings feels that this made it so that OSI had absolutely no chance of success. So what ever the merits of having a set of open OSI protocols, it was a serious attempt to provide an available solution, and the Commission allowed the project to throw it away. OSI died at that meeting. Without available implementations, it had no hope. (Randall, 1997:218) Another thing worth saying is that because the Internet boomed and became increasingly popular, and TCP/IPs design had a layer devoted to the Internet, TCP/IPs popularity was again increased further as a result of the Internets rapid growth. One could argue that OSI, being a protocol that did not include a layer for the Internet in its design, was over-run by the Internets growth. A final factor I would like to mention is the belief that a main reason OSI was not a success was because it got too preoccupied with the standards process and attempting to approve too many that it became caught up with them. It is seen by some that this caused it to fail as it distracted OSI from the one single standard that it was supposed to produce, the following quote shows this. But ISOs plan to make the OSI protocols a single standard for all computer users was defeated by ISOs own practice of approving multiple standards. (International Standards). To conclude, the concept of layering within networking software is in usage as it provides many advantages in terms of the softwares performance itself. Although, it does also pose some disadvantages, I feel they are small in number are not strong enough to outweigh the advantages. My analysis of the two networking protocols, OSI and TCP/IP, shows their main differences in terms of technical as well as social factors. I have also discussed the two differing impacts the protocols had in the world of networking and have attempted to explain why by looking at important factors associated with their diffusions. From my analysis, one can see that OSI was mostly a failure, as opposed to TCP/IP which won the protocols war and is in large international usage today.

Obsessive love in Great Gatsby by F. Scott Fitzgerald

Obsessive love in Great Gatsby by F. Scott Fitzgerald In The Great Gatsby, Jay Gatsby is portrayed as a naive and heartbroken man who will do anything to revive his relationship with the love of his life; even if it means reliving the past. Gatsby is a victim to temptation, manipulation, society and obsessive love. However it is because of this obsessive and incessant love that the rest of his problems unfold. He is so blinded and determined to gain the approval of his former lover, he allows himself to be made a mockery by society.It is made clear that Gatsby moved to West Egg for the sole reason that the love of his life, Daisy Buchanan, lives with her husband Tom in a house within sight of Gatsby‚s mansion. ‚“I think he half expected her to wander into one of his parties, some night‚…but she never did‚” (Fitzgerald.4.84). As Daisy‚s friend Jordan explains the situation to the narrator and Daisy‚s cousin, Nick Carraway, she notes that although Gatsby threw countless parties that were no interest of him in hopes that Daisy would one day stumble in, she was clueless to how very close Jay Gatsby was to her.Two Wire haired Fox Terriers. Listed on Flickr as ...Gatsby lacked the courage to approach Daisy, even though he worked his life around his dream of seeing her again.Gatsby was referred to by the socialites as ‚“new money.‚” Living in West Egg was less respectable then living in East Egg. The social structure was not of much concern to Gatsby and he paid little attention to etiquette or class. His obsession with Daisy took top priority, and while his intentions were sincere, Gatsby put himself in positions to be made a fool. ‚“My God, I believe the man‚s coming‚…Doesn‚t he know she doesn‚t want him?‚”(Fitzgerald.6.109). When invited by the Sloanes, a wealthy couple from East Egg,

Data Integration and Data Quality

Data Integration and Data Quality Data is very crucial to organizations because it is the major reference tool that can be used when decisions are to be made. There are two elements of data that go hand in hand and they are namely data integration and data quality. Data integration involves merging information from various sources to make a single pile of information that can be understood by users.Advertising We will write a custom essay sample on Data Integration and Data Quality specifically for you for only $16.05 $11/page Learn More This is because when a user has to extract information from different sources it might be confusing to him/her hence may not be helpful. On the other hand, data quality entails accuracy and appropriateness of the information obtained from databases. This paper focuses on the differences between the two aspects of data and reviews their importance to companies. Most people think that data quality and integration is one and the same thing but this perception i s only from the perspective of a lay man. The two elements of data, that is, integration and quality are different but we need them both hence we cannot ignore either of them because they are equally important to companies and individuals. In this age of electronic transactions we need to make sure that we minimize errors and also make it simple for our consumers to grasp something from the information that they get while interacting with our systems in their day to day operations. Imhoff (2005) argues that failure to emphasize on quality and integration can lead to decline in business because customers will opt to revert to old manual techniques. Most people emphasize quality more than integration. In the final end the latest developments in technology will loose its importance if the systems are not user friendly. The systems that most companies and other institutions have rolled out were meant to make work easier both to consumers and companies’ staff. They were invented w ith the aim of improving company’s’ performance and productivity but the improvements cannot be realized if the systems don’t work as they were designed to perform. This refers to the way they process information that is input by the users. When system errors occur it is the software developers who bear the most burdens. It should be known that erroneous transactions and information occur when users don’t provide the correct details as required by the system. For instance, when one is making cash withdrawal from an automatic teller machine he/she is responsible of the response that will be provided by the ATM machine. If the customer does not enter the correct pin number, the transaction will not take place and the ATM card will not be dispensed by the machine. This is one of the best examples of how systems can be designed to deal with data quality.Advertising Looking for essay on it? Let's see if we can help you! Get your first paper with 15% OF F Learn More Data quality is one of the protective measures that is highly valued by most companies because the records that are stored in databases can be used to trace events and for the referencing to be useful the data has to be free from errors. The data must be encoded appropriately because data can have common characters such as customer names which can be shared by various people. According to findings by META Group (2004), in data quality the main areas that attract attention are correctness, accuracy, completeness, and relevance. The correctness bit of data has been covered in the previous paragraphs. For data to be of good quality it must be complete because if some bits are missing the systems may encounter errors and fail to process the provided data. For instance, if customer’s date of birth is missing in its respective field, we can say that the data is not complete because the system cannot generate such information on its own unless it is prov ided by the user. Most of the time the missing bits could have been omitted erroneously when the data base was being developed. At times some bits of data are erased by mistake hence the ones that are left don’t make sense. In such cases the lost or missing data has to be recovered using the relevant technologies. This is because companies cannot make important decisions when the data they are referring to is incomplete and incase a company goes ahead to make decisions without complete data the company could incur losses owed to poor strategies which are caused by misleading information (Barney, 2004). We know that records are used when making budgets and can also be referenced in future while making decisions hence companies of these days don’t compromise on data quality. In fact there are software programs that can be very useful in tracking events leading to data loss. Moreover, data should be backed up and stored in a different location so that incase a fire destro ys the company premises its data will remain intact. Data should also be updated regularly for it to retain its quality. This is because outdated data can not be useful when making decisions. It is therefore recommended that data should be updated with change of events. For instance, in health records the data should incorporate current events in the patients’ data such as the medical procedures and health developments that have been reported by the patient such as number of births. In addition, it would be best to include new items that have been introduced by the company in the data base. When this information is not added to the existing information concerning a particular patient it might be difficult for medical personnel to make decisions concerning that patient and problems can occur due to lack of certain information. Besides, the information in the database needs to be correct for it to be useful because if it is based on estimation it could be misleading.Advertising We will write a custom essay sample on Data Integration and Data Quality specifically for you for only $16.05 $11/page Learn More This implies that the figures and other characters should be exact. For instance, the age of the customer should be accurate and this accurateness should also be applied in company information such as location. This is because sometimes the customers want to visit the company premises but then when they access the site map of the company location it does not reflect what is on the ground (Pipino, Lee, Wang, 2002). Data integration incorporates data from other records to make a comprehensive data depending on who will need that data and how it will be used. Integrating data saves both time and money that would be spent viewing individual records. It comes with convenience for the company and its clients. The information can be arranged in a way that only data within a specific range is available to the user instead of availing a ll the data while the majority of data is irrelevant to the user (Berson Dubov, 2007). Before data can be integrated, it is important to focus on how the data is laid out in their respective sources. This means that experts have to analyze the structure of data and design a newer structure based on the compatibility of data from various foundations. This is because there are some fields which do not match and hence they may cause the data to loose its relevance to the user. For instance, in institutional records the data fields about lecturer’s date of birth may not match with students records hence the person who is deriving the integration should incorporate data based on the relationship between the data fields. Data integration is useful while making decisions because it allows the users to make comparisons of various departments in their companies. For instance, for a company to make decisions regarding loss and profits it has to focus on the records from purchases and compare the information provided to that of sales records. Data integration fosters reliable presentations because repetitions are avoided hence the system is able to deliver the required results and thus achieve customer satisfaction (META Group, 2004). For instance, when a customer is opening a new account in a company’s website if she/he enters a username that already exists, the system will notify him/her and will probably provide suggestions. When data from various databases is merged it is easy for administrators of a company to foresee events before they take place. These events include decline in sales and other disciplines that are linked to company performance.Advertising Looking for essay on it? Let's see if we can help you! Get your first paper with 15% OFF Learn More For instance, if the performance from a particular department starts to fall the management will realize in good time and thus take the best action to caution the company. When data is not integrated risk management can be difficult to analyze because people would access the records that are relevant to them and ignore the rest. Data integration promotes simplicity because processes take a shorter time to be completed unlike when data is stored separately. When data is stored separately systems are forced to check for information from every individual database which takes a lot of time. This is because it has to select the data that is required from a huge amount of data. When data is integrated the required information is already grouped in one category hence processing it becomes easier. In conclusion, data quality and data integration are two different aspects but they are related because they belong to the same entity which is data. The two aspects are very important and thus sh ould be given appropriate importance because they are the elements of reliable data. Organizations such as IBM have been able to develop applications that help companies to integrate their data from different sources. This fosters data quality and thus improves productivity. Therefore, companies should manage their data well without compromising the two aspects of data. References Barney, B. (2004, June 18). Put your faith in CRM’s stewards. TechTarget.

Probability for Managers Essay Example | Topics and Well Written Essays - 1750 words

Probability for Managers - Essay Example The growing uncertainties under which managers must function, is a feature of the conventional environment (Daum, 2004). The aspect of uncertainty is exacerbated by information overload. Studies confirm that the information available to managers exceeds human capacity to process and to use such information. This makes for very difficult operating systems for managers. A third aspect of management practice is that most processes involve groups and teams. Even where final authority rests with an individual, the varying capabilities of managers to focus and to absorb information, requires that a common platform is created, so that each participant can express his or her views. Dissent is often the result of opposing parties basing their opinions on different scenarios, which they think is probable. Scientific application of probability theories has therefore a watershed role in building common understanding, if not consensus in teams that run firms. Formal probability techniques have been used in research functions of firms for a long time. Market Research, Clinical Trials and all other experiments to study the safety and efficacy performances of new products, use probability methodology. Random number generation and use, sampling, determination of significance and confidence levels all depend on probability science. Managers who are not formally trained in mathematics, or who do not remember their academics, may use outputs stated in qualitative terms for their decisions. This can lead to critical matters being effectively delegated to specialists who understand mathematics. Many examples of such distortion can be found in the high-profile pharmaceutical industry. Products have been released for the market, though research showed the probabilities of side-effects and adverse events. Managers in the concerned firms, regulators and doctors have all been victims of their ignorance of probability science, in taking decisions that were to subsequently cost consumers dearly! This trend will continue as technology takes us in to fields with multiple outcomes. It highlights the need for modern managements to fully understand the conclusions of formal probability methods. Insurance is another traditional field for the use of probability (Matthew & Stewart, 1999, p 2). The industry that provides cover against premiums depends on probability theories in large measure for their sustained probability, as indeed do all bookmakers involved in structured and informal gambling operations of all kinds. Firms with large capital assets often invest in internal positions, using specialists to determine their insurance policies and practices. Product liability is often determined in companies by people without adequate grounding in the mathematics of probability: under provision for related claims is often the result. All products and services that have potential implications for human safety and in terms of environmental impacts need the systematic and continuous application of established and proven probability techniques, for appropriate decision making. Stock valuation and its future course have emerged as industries in their own rights with the development of bourses world wide and the spread of the financial services and merchant banking sectors. Mutual funds also depend almost entirely on future estimates of market capitalization. Forecasts of scrip values started with simple regression and
