Experimental Designs II - Assignment Example For example, in a 2x2 factorial ANOVA with levels A1 and A2 of Factor Aand levels B1 and B2. An ANOVA test would test the significant differences between the marginal means, which are called simple Main Effects of each factor. This is because they illustrate the overall difference between the levels of each factor, independently of the levels of the other. The ANOVA also tests for the significance differences between the Cell Means; in other words, the four means relevant to the AxBinteraction effect (Jackson, 2012). According to Jackson, the test also determines if the effects of the independent variable (IV) are independent of each other, or whether the effects of one IV depend on the level of the factor. Key effects are differences in means over levels of one factor that is collapsed over levels of the other factor (s) (Jackson, 2012). No.6 The difference between a complete factorial design and an incomplete factorial design is laid out in how experimental conditions are dealt wit h. A Complete Factorial Design (CFD) consists of all factors and levels of each factor, it is also capable of estimating all factors, and their interactions (Jackson, 2012). An incomplete factorial design is arrived at when experimental conditions are removed from a complete factorial design. ... No.8 The difference between a two way ANOVA and a three-way ANOVA is that a two-way ANOVA test is used when there are more than one IV requiring multiple observations for each IV. The two-way test determines the main effect contributions of each IV and indicates if there is a significant interaction effect amongst the IVs. The three way ANOVA is used to determine the effect of three nominal predictor variables that are based on a continuous outcome variable. The three-way test evaluates the effect of the IV on the expected outcome together with their relationship in the outcome (Jackson, 2012). Random factors are considered to have no statistical impact on a given data set, unlike systematic factors that are considered to hold statistical significance.

Write a ONE-PAGE essay, including a brief summary in the first half Essay

Write a ONE-PAGE , including a brief summary in the first half and your reflection in the second half - Essay Example The questions asked is whether the huge amount of money utilized since the 9/11 has been utilized well to curb terrorists and protect the life of the people in the United States of America (Hale, 3). Dana Priest traces the journey from the September 11 bombing to the Boston Marathon bombing as well as investigates the efforts taken by the federal agencies tasked with the mandate of keeping the citizens safe during the twelve years of battle against terrorism. The movie outlines the governments developed after the 9/11 for the purpose of preventing future attacks and hunting terrorism. The second video is about the Rise of ISIS. Martin Smith investigates the mistakes and the miscalculations behind the brutal rise of ISIS even after the final departure of the American troop from Iraq in 2011. The video is a fast flowing and dense narrative focused on the failure of the Shiite-led Iraq government to share power with the Sunni minority and failure of the United States government to act when the Sunni militant exploited the available situation for their own gain. The blame is quite directed on president Obama and the former Prime Minister Nuri Kamal al Maliki. It is only Martin Dempsey, the Joint chief of Staff’s chairman, who speaks in defense of the government and the Obama administration (Fuchis, 4). The interview is accompanied by a flood of images that will have numbing and mesmerizing effect. It shows bombings, steady montage of protests, disturbing militant video of serial executions as well as battle footage. Basing on the first video footage, I believe that the government has made numerous steps in controlling frequent terrorist attack following the September 11 bombing on the US soil. Despite the efforts done to combat terrorism, the government was not prepared during the second Boston attack (Fuchis, 4). The Boston marathon attack has raised so many questions on whether the government has done enough following

The detailed information listed below - Essay Example It was also essential to minimize family control along the value chain by hiring competent managers who understood the dynamics of international trade. The removal of family control promoted the global appeal since shareholders feel part of the organization’s decision making. The other way of enhancing cost reduction measures was through the development of quality and customer focus. This implies that the Indian firms hired technology that enabled them to produce quality goods and services for their clients. It was crucial to produce commodities that match customers’ preferences and diversity in other foreign markets. High quality production enables firms to attract customers since this eliminates competition from other local firms in the same market (Halder and Rakshit 16). The strategy of cost reduction was the viable one because it increased earnings and global presence by decreasing the operation costs. The other reason was that it enables the hiring of professionals to operate the family business, which reduced internal interferences. It is also the best strategy because it ensured the production of quality commodities to counter competition from other international firms (Halder and Rakshit

Stratejik Financial Management, provide an evaluation of two projects, Essay

Stratejik Financial Management, provide an evaluation of two projects, both with five year expected lives and identical initial outlays of 110,000 - Essay Example A thorough analysis of what a business venture or investment will impart the company is one of the most important steps in sustaining profitability, maximizing company's resources, and accepting or rejecting prospective projects (Brealey et al, 2005). The payback period is regarded and widely used because of its relative simplicity. Managers prefer to use it because it is generally easy to memorize and to use (Peterson and Fabozzi, 2002). However, this technique disregards the additional cash flow which can be recouped from the project as it only focuses on the time when the whole investment will be recovered (Higgins 2005). Since the concern of the payback period is when, it does not really tell a business organization whether an investment is worth pursuing or not. Also, because of the relative view of managers on when the amount of investment should be recovered, there is no definite conclusion if project should be accepted or not. The following tables show the computation of the Net Present Value (NPVs) of the two projects under consideration. Using the expect annual cash flow, the computed NPV for project 1 is $31,740 while it is $34,200 for project 2. If NPV is only the man consideration of the business organization in capital budgeting decision, it is apparent that both of the projects should be accepted. It should be noted that using the NPV method, any project which does not yield zero NPV should be considered and pursued by the business organization. Thus, in the case of the evaluated projects above, both should be considered as they both yield positive values of NPV. 4. Explain the logic behind the NPV approach. Net Present Value (NPV) is the difference between the present value of cash inflows and the present value of cash outflows (Keown, et al, 2005). The Net Present Value (NPV) analysis is very much different from other capital budgeting techniques like payback period because it takes into account the time value of money. In the computation for total cash flow, it also takes into account the total cash flow from the investment including the depreciation and the tax shield resulting from it. Starting from the expected annual cash flows from the prospective project, managers should assign a specific required rate of return, that is, the rate of return that the companies want to generate from the investment. This is often indicated as an interest rate. For example, if the company's rate of return is 12%, the company will only accept investments which will yield 12% or higher. This method recognizes that the value of dollar today is greater than its expected value tomorrow. Thus, all the cas h flows are discounted according to the required rate of return. After generating the present value of all the expected future cash flows, it then takes the sum of these present values. Logically, if the sum is positive, it means that the project exceeds the required rate of return. In contrast, if the NPV is negative then the project fails to generate the set return. This technique is favored by more economists and managers because it is more realistic. 5. What would happen to NPV if the required rate

A framework for knowledge based educational decision support system Literature review

A framework for knowledge based educational decision support system - Literature review Example In the modern world of technological development and growing need of easy maintenance of data Knowledge base system are in huge demand. The systems based on Knowledge base are known as Knowledge base system.It mainly comprises of storing, organizing and the retrieval of data in an efficient way. This gives an insight of the relations, patterns and the principles behind certain decisions taken in a practical manner through proper understanding. This system can also be applied in Educational Decision Support System (EDSS) for an easy decision taking procedure in the educational institute and normalizing the procedure for management of institutional admissions. Background of knowledge based educational decision support system Knowledge based decision support system is mainly concerned with taking decision in critical situation which are mainly done by skilled personnel on a specific domain. The success of such a system is mainly dependent on the knowledge it comprises of in the system w hich can generalize the variation in the decision of the management through a computerized way provided on time (CEBE, 2006, p. 1). But as stated by the author it is not about taking decision for the user rather it is just providing access to the database of information which will help the user in taking decision regarding an issue which might arise in the process. In educational institutes the process of admission is a difficult task for the management to handle due to the variation in the educational backgrounds of the students applying for different courses of the institutes and abiding by the policies of the institution, the management not always takes the right decision in the selection process resulting in the difficulty in managing the enrollment process for the higher education. This gave rise to the requirement of the relational database management system of the educational statistics of different universities, campuses, schools; faculty members etc. under a centralized dat abase for an easy access to the entire information at one place and establish a department of statistics for the planning process. To achieve an effective decision making process the personnel need to understand the basics of the process and past experience on same type of situation is an important tool for an efficient and feasible outcome of the problems (Pheng, 2005, p. 2). Need of educational decision support system The admission procedures of different countries in the word are not the same way everywhere. These variations in the admission procedure give rise to the need of standardization of the process to help students for a proper evaluation and understanding of their knowledge and skills. There are various problems which arise due to these variations resulting in the need of an efficient educational decision support system (EDSS). These differences can be described as follows- The huge demand in higher education in this modern world needs a proper implementation process for the specific major subject selection for the students according to their merits and credibility. The social impact of the family plays a vital role in the selection process of the students but proper selection is required based on merits rather than influence from family. The evaluation process of students in several countries like Saudi Arabia adds an extra overhead for the students and they lose unnecessarily one year in their career for the selection process in their eligible courses. The government and the private university difference in selecting the major based on the financial capabilities need a process of standardization of the whole system. According to UNESCO, various countries like Saudi Arabia are facing challenges from the growing need of improving the quality and

Firewalls and Intrusion Detection Systems Assignment

Firewalls and Intrusion Detection Systems - Assignment Example What are the similarities and differences of these two systems? Intrusion detection systems are software applications or devices that detects and monitors malicious activities of violations of policies provided. In addition, the application provides reports and information to management stations. The application has different ways and mechanisms that may detect network traffic from different sources. In general, intrusion detection systems focus on detecting network incidences, logging information of users and reporting log in attempts (Ross, 2001). Moreover, companies use the systems to monitor their existing security systems. This is done by detecting issues with security policies and creating documentation on existing network issues. In addition, the system may provide recommendations on how to update existing security policies. The main objectives of IDS are analyzing and monitoring system activities and users, taking part in system audits, analyzing the safety of content used and required, detecting unusual activities and comparing partners to malware patterns. One major weakness of the system is that it must contain human operations which may hinder the effectiveness of automated functionality (Verma, 2008). On the other hand, firewalls are also used to increase the effectiveness of network security approaches. Firewall protects network security systems from access from unauthorized sources. Verma (2008) is of the assumption that firewall protect security prior to their access. The author further points out that the security system relies on its ability to protect access and distortion before threat is launched. To increase the effectiveness of the system, they are regularly updated to be able to identify advanced network threats. Firewall security systems also ensure the safety of the network connection used in a business. With a protected security firewall detects both incoming and outgoing packets.

Cisco Australia Case Study Example | Topics and Well Written Essays - 3000 words

Cisco Australia - Case Study Example The company could well be on its way to wearing Australia's best employer crown. So what is Cisco all about Cisco, which was founded in 1984 by two computer scientists from Stanford University, began life as a manufacturer of routing systems. Since it sold its first router in 1986, the company has more than lived up to its vision of 'Changing the Way We Live, Work, Play and Learn'. Apart from its core development areas of routing and switching, Cisco has now branched into various technology-related fields like IP communications, wireless LAN, home networking, application networking services, network security, storage area networking and video systems. The company, which has its corporate headquarters in San Jose, California, soon became one of the leaders in the global networking industry with a presence in over 115 countries. Today, it has a 47,000-strong employee base. Using the acquisition-partnership route, Cisco managed to make inroads into multiple fields. Today, Cisco's products provide solutions to a wide range of customers from business enterprises like corporations and government agencies to educational and research institutions. In 1994 Cisco set up base in Sydney, Australia, which was one of the company's first operations outside the United States. Today, Cisco Australia operates from around six cities and has over 600 employees on its payrolls. Australia is home to the company's Asia Pacific Technical Assistance Centre and Customer Assurance Group. Here's a list of the awards that the decade-old Cisco Australia won: Prime Minister's Award for Community Business Partnerships in August 2001. No 1 in the Hewitt Associates survey "Best Employers to Work for in Australia" in the under 1,000 employees category in 2002 and 2003 MAS National Award for Corporate Citizenship at the 2005 Australian HR Awards. [B(1.1)] Does Cisco Fit The New Workplace One of the main reasons for Cisco's almost meteorical rise to success was its ability to adapt to the new work order. Around 15 years ago, the same time that Cisco began operations; the new workplace became an important word in management parlance. Computers and the Internet were changing the way the world worked. Managers realized they needed to implement solid workplace strategies, to provide the infrastructure for enabling global, 24x7 work processes and remote collaboration "anytime, anyplace." (Aperture Technologies 2006, online ) This 'anytime, anyplace' strategy proved extremely beneficial for both organizations and their employees. It gave them considerable freedom, as they could now be mobile and work from just about anywhere. Freed from geographical and time constraints, an organization's managers could employ qualified people from just about anywhere in the world. A look at Cisco's growth graph during the past 20 years shows that in just over a decade, the company had spread its wings across continents. It managed to get the best in terms of qualified employees and a bigger customer base. A downside of this new workplace was that it put a strain on the companies' infrastructure and also affected workplace dynamics. This meant that enabling and empowering employees with a superior workplace was of paramount importance to the
