P.O.S 2 - Essay Example Benefits of the POS System The POS system being online will ensure that all across the Wal-Mat store there will be real and up dated POS solutions. In addition, since the POS system is custom made it will be custom made and thus compatible with most of the programs and hardware, which are to be installed. Furthermore, it will ensure that there is less inventory shrinkage. This is because through POS system it will be easier to keep track of obsolete and damaged inventories. Because of the effectiveness with which customers are served, it will ensure and lead to more customer service efficiency, customer satisfaction and customer retention and loyalty. It will facilitate timely and accurate reports as well as fast and effective analysis of sales date which is paramount to management information for decision-making process. In addition, the online POS software package will offer the advantage of management through remote access i.e. while in different store and while on leave. Moreover , having installed POS system Wal-Mat can easily expand in case of increased customers. This is because it only needs to mount new computers and other relevant hardware to create a new service station. The other minor benefits that Wal-Mat will get by setting up the POS will be prevention of theft, accuracy, and effective inventory management. ... Furthermore, with the retail POS system Wal-Mat will experience potential security risks with regard to software corruption by viruses, credit cards, and debit cards. Moreover, considering that the POS system is custom made, with the software applications used there will be need for regular updates to the system that may be done at an extra cost. POS Contingency Measures Since running of the POS system will be dependent on the electricity for smooth running, implies that in case of power outages the business will stop. These business standstill means loss of revenue, dissatisfaction of customers and under utilization of resources. Wal-Mat to combat electricity failures has bought and installed a diesel driven generator with the capacity to run the POS system for more than 12 hours. In addition, UPS s- uninterruptible power supply - have been fitted on every computer. This is to ensure smooth transition and business continuation while switching to the generator. Wal-mat has also set u p another back-up server computer in another independent location that store up real-time transactions happening in the main business stalls. This is meant to militate against any outages of the POS system in case of fire breakout in the main business area. In addition, after every 1 hr of the normal business hours, it is a requirement that there be a print out of sales receipts for every one hour. This is to ensure that in case of failure of the two back-up servers there can be hardcopy back up to mitigate it. Weakness and Recommendations to POS System Due to the continued high customer satisfaction, there has been an influx of new clients to our business, which has resulted to slower than normal

The impact of Al Jazeera channel relationship with the State of Qatar Dissertation
The impact of Al Jazeera channel relationship with the State of Qatar to other countries - Dissertation Example 20-26, 2007), things have changed abruptly and mediaââ¬â¢s role has become decisive where breaking news has become a tool for changing of governments, as well as tensions between the nations. In this era of globalization, media has become an evident tool of bringing change through communication around the globe, and evidently, media has been benefiting from this huge authority and responsibility; however, it is an observation (Ingram & Dodds, pp. 58-69, 2009) that it has resulted in increment in governmental crisis in a number of countries. Research Statement In this regard, the researcher will put efforts on the below mentioned research statement to achieve aims and objectives of the research: ââ¬Å"To identify and analyze the impact of Al-Jazeera Channel Relationship with the State of Qatar to other countriesâ⬠Aims and Objectives Some of the particular aims and objectives of the proposed research are: Identification and analysis of the role of Al-Jazeera Channel in Arab r egion Scrutinize the extent of Al-Jazeera impact on the State of Qatar specifically Study the nature of Al-Jazeeraââ¬â¢s relationship with the State of Qatar Investigate the impact of abovementioned relationship on Qatarââ¬â¢s relations with other nations Identify and recommend strategies that may ensure positive impact of studied factors on performance and reward management systems of business organizations Research Questions & Hypotheses In brief, the research will focus on the following research questions: What is the role of Al-Jazeera in Qatar? What is the role of Al-Jazeera in Arab region? What is the role of Al-Jazeera in enhancing/deteriorating relationships of Qatar with other nations/regions? The below-mentioned literature review has led to the following hypothesis, which will be under testing in the process of research: 1. Al-Jazeera is positively under correlation with Qatar. This means that Qatar will be able to resolve its various bilateral issues based on functi ons and operations of Al-Jazeera channel. LITERATURE REVIEW Brief analysis of literature (Miles, pp. 23-29, 2005) has indicated that neighbors Qatar and Saudi Arabia are almost similar in terms of their social and cultural existences, as both seem to be following ultra-sensitive Wahabbism (Tatham, 2005). However, one single notion that differentiates the State of Qatar from Saudi entity is television channel of Al-Jazeera (2011) that has been successful in ensuring an individual identification and social existence of Qatar around the globe. In particular, Al-Jazeera (2011) means ââ¬Ëthe islandââ¬â¢ in literal perspective; however, from a critical perspective, Al-Jazeera (2011) is a satellite television channel that has been able to achieve success in a short period; however, has acquired this success with huge volumes of antagonism and controversies for itself, as well as for the State of Qatar (ICWN, 2010). Still, even after huge number of controversies, Al-Jazeera (2011) has been unbeaten in catering roughly thirty-five million Arabs by providing international news. In addition, scrutiny of media reports has indicated that Al-Jazeera (2011) has even been able to create disturbance for big names, such as BBC, CNN, etc by dominating on the news related

Cortes 2nd Letter Back To Spain Essay Example for Free
Cortes 2nd Letter Back To Spain Essay To systematically rid the world of a civilization takes not only military genius and advanced weaponry, but also a lot of something else. This something else is quite unknown though. While Cortes and other Spaniards at the time believed that his conquering of the Aztecs was purely courage and Gods will, I believe that it was not so much of those, but a whole lot of luck. In Cortes second letter to the Emperor he discusses his battles with the Aztecs within the city limits of the Aztec capital, Tenochtitlan. While writing about the inner-city war between the massive army of Aztecs and the handful of Spaniards, Cortes credits his victories to the bravery of himself and his troops. Not to mention, throughout his letter of conquest, Hernan Cortes brings up God. This in turn, gives me the impression that he, like most Christians during this time, also credits God for the victory. Simply saying that they were enforcing Gods will. I on the other hand, mainly credit Cortes destruction of the Aztec empire to the Spaniards advanced weapons, military intelligence, and a hint of luck. While the Spanish were using guns to slowly mow down the constant waves of attacks of the Aztecs, the Aztecs themselves were armed with mere rocks. This creates a mild advantage for the gun bearing Cortes and his men, but not too large of one, due to the limited number of Spanish men and the almost infinite number of Aztecs. This is where I believe a lot of luck came into play for Cortes, the fact that he and his men fought their way out of the island city of Tenochtitlan is simply amazing. To say that you are carrying out the will of God is quite hasty and cannot be supported either way. This in turn means that the something else that aided Cortes in his victory can only be explained as luck at the moment. Since there is no real way to discover the causes of Cortes upset victory of the Aztec empire, one must figure it was the weaponry, intelligence, and luck. No matter what it was, it definitely was pivotal in the conquest of Mexico for the Spanish empire.

Affirmative Action :: essays research papers fc
Imagine a person has hopes of landing their dream job and is applying for a position at a very successful company. They have more than enough qualifications but for some reason do not get the job simply because the company had to hire a woman or minority to satisfy its policy. What policy you may ask, born to the civil rights movement three decades ago, affirmative action calls for minorities and women to be given special consideration in employment and education. Affirmative action is one of the many problems with todayââ¬â¢s society and should not be allowed to be used in any situation. This policy is intended to give both parties an equal opportunity to be a successful individual and make it in todayââ¬â¢s society. It is morally wrong because the battle for equal rights has been won and favoring members in one group over another is totally unfair. Others see it as the only opportunity for minorities and women to rise up and obtain the same education and career opportunity a s everyone else. à à à à à Before writing this paper I had not known a lot about what affirmative action meant, but now I can say I strongly disagree with its meaning. I myself had a run in with affirmative action just recently in this past month. One of my close friends received an acceptance letter from the University of Michigan and I couldnââ¬â¢t believe she got in because her score on the ACT test was very low. She also didnââ¬â¢t have very exceptional grades in high school, which meant she could have only gotten in because she was of Hispanic origin. Giving someone more rights and opportunities than others just because of a personal trait is not only unfair but totally defies everything that was fought for in the civil rights movement. Would giving someone an advantage in a situation such as education influence them not to try as hard if they were to have the same opportunity as everyone else? Robin Kelly stated: ââ¬Å"Sadly, I run into many young people who do not have a sense of what is possible, a visi on of what this country could become. Rather, they accept the current arrangements as an immutable given and figure how best to survive within themâ⬠(80). Kelly suggests that todayââ¬â¢s youth have no intentions of changing the world and only intend to live in it how it is.

Case Predicting Performance
The pressure of the SAT exam is very great, and many students suffer from test anxiety. The results, therefore, may not truly reflect what a student knows. There is evidence that coaching improves scores by between 40 and 1 50 points. Test scores, therefore, may adversely affect the chances of acceptance for students who cannot afford the $600 or $700 to take test-coaching courses. Are Stats valid, or do they discriminate against minorities, the poor, and those who have had limited access to cultural growth experiences?Alternatives: 1- Keep student selection criteria and its weights as it is for now ââ¬Å"including SAT at 0%â⬠2- Increase SAT weight 3- Decrease SAT weight to 20% and add to the criteria intelligent test with weight of Alternatives Evaluation: 1 .

The Devil And Miss Prym - 1713 Words
Our daily life is full of decisions. Decisions of right or wrong, good or evil, discovering who we want to be down at our core protagonist or antagonist. In Coelhoââ¬â¢s novel The Devil and Miss Prym, Chantal must make these decisions. When a stranger strolls into her small village of Viscos, Chantalââ¬â¢s inner Devil is prompted. The stranger is testing human nature and uses Chantal as his main pawn. He shows her a bar of gold buried in the woods that she could steal at any time during his week stay, and he shows her another ten bars of gold that the village could have if they chose to commit a murder. Chantal was an adult having to choose how to address the strangerââ¬â¢s proposition, but Bruno in The Boy in the Striped Pajamas (a motion picture) also has to battle his inner devil. In the movie Bruno is an eight year old boy living in Germany during World War II. Bruno does not understand the war, or the promotion his father has been given by Hitler. His inner good verse e vil is trying to dissect all that he is learning from his new home next to the ââ¬Ëfarmââ¬â¢ where the workers wear striped pajamas all day.

Study On The Average Number Of Employees Index Finance Essay - Free Essay Example
Sample details Pages: 5 Words: 1374 Downloads: 3 Date added: 2017/06/26 Category Finance Essay Type Research paper Did you like this example? The goal of this article is to study the direction and the intensity of the relationship between the Average Number of Employees Index and the Gross Domestic Product Index. The study is done by analyzing quarterly data from 2007 until 2009 from Romania and by applying statistical and econometrical methods: the graphical method, the regression function, the correlation ratio, the determinant coefficient and the dispersion analysis. The Trimester Evolution of the Average Number of Employees and the Gross Domestic Product Indexes between 2007 and 2009 The Gross Domestic Product (GDP) is the main measurement indicator of the macroeconomic results of a country and the main economic result aggregate in the National Account System. It expresses the gross value of the final goods and services produced within a certain time period by the home and foreign economic agents within the country. It can be computed by two different methods that lead to the same result, with some statistical differences based on the usage of different sources of data. The production method (the value added method) is based on the aggregation of the final product and goods flows obtained by the economic agents. The final usage method (the expense method) starts from adding the elements in which the final economic assets are used (goods and services) evaluated at the market prices, less the value of the imported goods. Table no. 1 GDP Indexes between 2007 and 2009 (% of the corresponding period from the previous year) Year Trimester I Trimester II Trimester III Trimester IV 2007 106.1 106.0 105.9 106.8 2008 108.5 109.6 109.4 103.1 2009 93.8 91.3 92.9 93.5 Source: Monthly Statistical Bulletin no 1/2010, no. 5/2010 Fig. no. 1 The GDP Indexes Evolution between 2007 and 2009 By analyzing figure no.1 a linear growth trend is observed for the GDP indexes between the first trimester of 2007 and the second trimester of 2008, when it reaches a maximum of 109.6%. This is followed by a drop until the second trimester of 2009 when a minimum value of 91.3% is registered, and a growth trend until the fourth trimester of 2009.

The information obtained is presented in the below table. Table no.3 The average number of employees indexes between 2007and 2009 (%) Year Trimester I Trimester II Trimester III Trimester IV 2007 102.3 102.8 102.9 103 2008 102.3 102 101.8 101.1 2009 99.7 96.5 94 92.3 From the below figure, a growth trend can be seen for the number of employees index between the first trimester of 2007 and the fourth trimester of 2009. The maximum is reached at 103% after which a linear decline follows until the fourth trimester of 2009, with a minimum value of 92.3%.

Our writers will create an original "Study On The Average Number Of Employees Index Finance Essay" essay for you Create order The correlation analysis between the average number of employees index and the GDP index The independent variable is the average number of employees index which is defined as X and the dependent variable is the GDP denominated as Y. The data to be used in the econometric study are presented in the table below. Table no.4 The average number of employees index and the GDP index between 2007 and 2009 Period I 2007 II 2007 III 2007 IV 2007 I 2008 II 2008 III 2008 IV 2008 I 2009 II 2009 III 2009 IV 2009 The average number of employees index (%) 102.3 102.8 102.9 103 102.3 102 101.8 101.1 99.7 96.5 94 92.3 GDP index (%) 106.1 106 105.9 106.8 108.5 109.6 109.4 103.1 93.8 91.3 92.9 93.5 By studying the figure no 3, it can initially be seen that the relationship between the two variables is linear. This hypothesis will be demonstrated subsequently through econometric methods. The linear regression equation is: (1) Figure no.3 The graphical represen tation of the relationship between the average number of employees index and the GDP index In order to determine the adjustment model parameters, and b, the below normal equations system will be solved through the Kramer method: (2) By analyzing the data from Table no.4 with Excel, submenu Data Analysis, the blow information was obtained: Table no.5 The index value synthesis The adjustment model parameters Correlation ratio Coefficient of determination Fcomputed Ftheory a -63.00394912 0.857644833 0.735554659 27.814998 0.000360739 b 1.651492787 By analyzing the data from the above table it is seen that the correlation ratio is R=0.857644833 that shows that between the average number of employees index and the GDP index there is a direct, strong intensity relationship. The coefficient of determination R2=0.735554659 points out that the independent variable influences the dependent variable in a percentage of 73.55%, which means tha t the average number of employees index variation influences 73.55% of the GDP index variation.The validity testing of the unifactorial linear regression model will be done by using the dispersion analysis also known as ANOVA method. By analyzing the data in from the table no 6 it is noticed that: The regression variance is . The residual variance is . The total variance is . Table no.6 ANOVA table Ãâ df SS MS F Significance F Regression 1 414.2122822 414.212282 27.814998 0.000360739 Residual 10 148.9168845 14.8916884 Ãâ Ãâ Total 11 563.1291667 Ãâ Ãâ Ãâ This is a simple relationship as there is only one independent variable: k=1. The number of analyzed pairs is n=12.Therefore we can compute the corrected dispersions: (3) (3) (4) (5) Th next step of econometric analysis is testing the validity of the linear model by applying the Fisher-Snedecor test (F Test). The hypotheses used to verify the validity of the linear model are: H0: the linear model is not valid. H1: the linear model is valid. By using the data from the previous table it can be seen that the computed value of the F test is Fcomputed=27.814998. The theoretical value of the F test is Ftheory=0.000360739, which is smaller than 0.05, therefore the H0 hypothesis is rejected and the H1 hypothesis is accepted, which means that the linear model is valid. The hypotheses for testing the correlation ratio are: H0: R=0 (R is not significantly different from zero, so R is not statistically significant) H1: RÃÆ'à ¢Ã ¢Ã¢â ¬Ã °Ãâà 0 (R is sign ificantly different from zero, so R is statistically significant). The Fisher-Snedecor test will be applied. The computed test statistic is: (6) . The theoretical value of the F test at the significance level ÃÆ'Ã
½Ãâà ±=0.05 is Ftable=4.96. Because FcFtable = the H0 hypothesis is rejected and the H1 hypothesis is accepted. This proves that the correlation ratio is statistically significant. In order to test the regression model variables, the following table will be used. The table was obtained with the Excel program, submenu Data Analysis: Table no.7 The variables value synthesis Coefficients t Stat P-value Lower 95% Upper 95% a= -63.00394910 -2.0095694 0.07222653 -132.8604781 6.852579882 b=1.651492787 5.27399259 0.00036074 0.953775609 2.349209965 The hypotheses for testing the a variable validity are: H0: a=0 (variable a is significantly equal to zero, so a is not statistically significant) H1: a0 (variable a is significantly lower than zero, so a is statistically significant). Because n=12 studied data, n30 we have a small volume sample, and a0, therefore the unilateral left t test will be applied. At a significance level ÃÆ'Ã
½Ãâà ±=0.05 , the computed value is tc= -2.0095694 and the theoretical value is t= -0.07222653 which is smaller than -0.05 which means that the H0 hypothesis is rejected and the H1 hypothesis is accepted. This proves that the a variable is statistically significant. The confidence interval is : -132.8604781 a 6.852579882. The hypotheses for testing the b variable are: H0: b=0 (variable b is significantly equal to zero, so b is n ot statistically significant) H1: b0 (variable b is significantly higher than zero, so b is statistically significant). Because n=12 studied data, n30 we have a small volume sample, and b0, therefore the unilateral right t test will be applied. At a significance level ÃÆ'Ã
½Ãâà ±=0.05 , the computed value is tc= 5.27399259 and the theoretical value is t= 0.00036074 which is smaller than 0.05 which means that the H0 hypothesis is rejected and the H1 hypothesis is accepted. This proves that the b variable is statistically significant. The confidence interval is : 0.953775609 b 2.349209965. 3. Conclusions Only after following the necessary steps: testing the model validity by using the ANOVA method, testing the significance of the linear regression models variables and establishing the confidence intervals, determining and testing the correlation ratio, the choice and usage of the unifactorial linear regression model is completely proven. By using statisctical and econometrical methods, it was confirmed that there is a very strong linear relationship between the average number of employees index and the GDP index. Therefore, by knowing the value of the average number of employees index at a certain point in time, the GDP index can be predicted.
