...history of modern computing into the following eras: 1970s: Timesharing (1 computer with many users) 1980s: Personal computing (1 computer per user) 1990s: Parallel computing (many computers per user) Until about 1980, computers were huge, expensive, and located in computer centers. Most organizations had a single large machine. In the 1980s, prices came down to the point where each user could have his or her own personal computer or workstation. These machines were often networked together, so that users could do remote logins on other people’s computers or share files in various (often ad hoc) ways. Nowadays some systems have many processors per user, either in the form of a parallel computer or a large collection of CPUs shared by a small user community. Such systems are usually called parallel or distributed computer systems. This development raises the question of what kind of software will be needed for these new systems. To answer this question, a group under the direction of Prof. Andrew S. Tanenbaum at the Vrije Universiteit (VU) in Amsterdam (The Netherlands) has been doing research since 1980 in the area of distributed computer systems. This research, partly done in cooperation with the Centrum voor Wiskunde en Informatica (CWI), has resulted in the development of a new distributed operating system, called Amoeba, designed for an environment consisting of a large number of computers. Amoeba is available for free to universities and other educational...

...Project Proposal. Title Shared Services a focus on Nigeria Financial Institutions. Executive Summary Shared services have been widely implemented in the public and private sectors of organizations around the world. The shared services phenomenal are spreading around the globe and financial institutions and others companies in African do not want to be left. However, with the fact that one of the basic advantages of shared services is cost saving and its leverages so much on infrastructure. Unlike Europe and America, African is still growing in the area of infrastructure and cost of labour is relatively low. This paper explores the shared service's model in financial institutions in Nigeria and reports the findings on share services meeting its objectives in developing countries. Nigerian banks are trying to compete with their international counterparts that have a presence in Nigeria and operating in the same business, cost reduction is a major advantage. Most of the International banks like standard chartered, Citibank, and Barclays use the shared service model and since none of these international financial institutions have their head offices and major businesses in Nigeria, they operate their shared service centre in any other geography. Keywords: Shared services; Financial Institutions; Nigeria 2. Introduction. Shared services refers to the concentration of services to one area or group of an organization where such services are previously...

...Service Request SR-kf-013 Ever wonder why certain banners or advertisements seem to contain information you are or were interested in? Online consumer behavior is being tracked all over the world-wide-web via cookies, Flash cookies, and “Web beacons” such as Omniture. Ad networks utilize information collected via various Javascripts and/or cookies to dynamically create content for users. One such Ad network called BlueKai actually allows its users to see a visual representation of the data being collected and shared about them. The amount and variety of data contained in user cookies alone is simply staggering! Many consumers today are beginning to wonder whether or not their privacy is at risk. With that in mind, proposing a system that tracks online shopping behavior introduces quite a few risks. Legal Concerns Where PII (Personally Identifiable Information) is concerned, so is the law. When handling behavioral data of any kind, it must be stored securely. If any PII is collected, certain disclaimers, agreements, opt-out opportunities, etc. must be in place in order to refrain from attracting legal attention. Cookies must be handled delicately as well, especially if they utilized to track users on our shopping platform. When a user deletes his or her cookies, that user should become a new user on our network. Holding onto a user’s cookies against his or her wishes can be pursued in a court of law, where we will certainly lose. To give a good example, one of the...

...TITLE: DESIGN ISSUES AND FUTURE TRENDS OF DISTRIBUTED SHARED MEMORY SYSTEMS ABSTRACT In these times, the distributed shared memory paradigm has gained a lot of attention in the field of distributed systems. This piece of work looks into different system issues that arise in the design of distributive shared memory systems. The work has been motivated by the observation that distributed systems will continue to become popular and will be largely be used to solve large computational issues. Since shared memory paradigm offers a natural transition for a programmer from the field of uniprocessors, it is very attractive for programming large distributed systems. Introduction The motive of this research is to identify a set of system issues, such as integration of DSM with virtual memory management, choice of memory model, choice of coherence protocol, and technology factors; and evaluate the effects of the design alternatives on the performance of DSM systems. The design alternatives have been evaluated in three steps. First, we do a detailed performance study of a distributed shared memory implementation on the CLOUDS distributed operating system. Second, we implement and analyze the performance of several applications on a distributed shared memory system. Third, the system issues that could not be evaluated via the experimental study are evaluated using a simulation-based approach. The simulation model is developed from our experience with the CLOUDS distributed system....

...Cookie Types and Ethics of Their Use Matthew Fones IFSM 201 06/30/2013 The purpose of this research paper is to identify and explain three commonly seen cookies used on the Internet, along with identifying any potential ethical issues with such activities. The two most commonly used cookies are session cookies, persistent cookies. I will also describe a third type of cookie known as a flash cookie. First I will define what a computer cookie is. A cookie is a piece of text that a Web server can store on a user's hard disk or equivalent. Cookies allow a Web site to store information on a user's machine and later retrieve it (Brain, 2000). Cookies are created when a user's browser loads a particular website. The website sends information to the browser which then creates a text file. Every time the user goes back to the same website, the browser retrieves and sends this file to the website's server. Without cookies, websites and their servers have no memory. Computer Cookies are created not just by the website the user is browsing, but also by other websites that run ads, widgets, or other elements on the page being loaded. These cookies regulate how the ads appear or how the widgets and other elements function on the page. The first type of cookie to be described is the session cookie. This type of cookie allows users to be recognized within a website so any page changes or data selection you do is remembered from page to page. The most common example of this functionality...

...rights reserved. ©2009 by John C. Maxwell ISBN: 978-1-59995-168-3 Introduction In all aspects of life, from the professional world to family interactions, good thinkers help solve problems. For 40 years, John C. Maxwell has studied and analyzed successful people and how they think. He has concluded that the way successful people approach the thought process is a key differentiator. In How Successful People Think, Maxwell discusses the 11 skills that good thinkers exhibit and describes how to adopt these skills. Maxwell recommends keeping it in a place where it will stimulate further thinking. 2. Spending time with good thinkers. Maxwell believes that to become a sharp thinker, a person must spend time with sharp people and observe how they think. 3. Thinking good thoughts. The thinking process is a discipline. As a result, it is important to make thinking a priority and to regularly take time to generate and develop thoughts. 4. Acting on good thoughts. The window of opportunity to act on promising thoughts is short. When a good thought arises, it is important to act on it quickly. 5. Allowing emotions to create another good thought. A person cannot wait to start the thinking pro- Getting Started with Better Thinking For a person to change the way they think, they must commit time to an ongoing process that is comprised of six steps: 1. Finding good input to start the thinking process. The thinking process can be initiated by absorbing good ideas from books, trade magazines...

...development of thought processing, (Berger, Chapter 2, 2008). This theory affects a person thoughts, attitudes, beliefs, values, assumptions, and actions. Piaget introduces cognitive theory in 1980 which eventually branched off into many versions that added insight to human development later on. However before that Piaget developed the central thesis of cognitive theory: how people think changes with time an experience, and thought processes always affect behavior, (Berger, Chapter 2, 2008).Piaget also broke the cognitive theory into stages: sensorimotor, preoperational, concrete operational, and formal operational(Berger, Chapter 2, 2008). All of these stages are age related and affect a person at a different point in his or her life. Another pioneer that developed a theory to explain human development is Lev Vygotsky he designed the sociocultural perspective. According to Berger (2008), Vygotsky studied cognitive competency among the ethnically and economically diverse people of his huge nation, as well as among children who were mentally disorder. The central concept of sociocultural theory is guided participation which is the technique that engages learners in joint activities, offering direct, shared involvement in several widespread cultural practices, (Berger, Chapter 2, 2008). Unlike Piaget Vygotsky believed that each human begins life knowing nothing about their own culture but learned by guided participation. Even though their views are different both shared common interest...

...GUIDELINES FOR THE Practical Book Review: James Petersen By Jacqueline McCluskey Student ID: L24900116 Presented to Dr. Gordon Bals In partial fulfillment of the requirements of Introduction to Pastoral Counseling PACO 500 Liberty Baptist Theological Seminary Lynchburg, VA February 3, 2012 PRACTICAL BOOK REVIEW ONE: James Peterson My Summation In the first part of his book, Dr. Petersen introduces the reader to Flat-Brain Theory of Emotions. Through this theory, he explains how emotions, thinking and relating abilities work and how what goes on inside of us comes out in the ways we communicate and act (Petersen 2007, 8). It is through the Flat-Brain Theory that the reader gets an understanding of why at times it is difficult to communicate with others. Also through this theory he explains how when a person’s emotions go into overload how it affects the way they think and interact with others. According to Petersen, emotional and relational overload can negatively affect the ability to hear, see, and speak (23-30). Within the Flat-Brain Theory the stomach begins to expand because it becomes overloaded with different emotions. These emotions then press the heart functions into bricks in the chest, which negatively hinders the ability to relate. This then affects the brain causing it to flatten. The brain becomes pressed against the skull resulting in our thinking, hearing, and seeing to be off. Therefore, the flat-brain person can’t hear...

...Appreciative Inquiry In Organizational development (OD), appreciative inquiry (AI) is a human resource management approach to organizational renewal. The basic idea is to build organizations around what works, rather than trying to fix what doesn't. A purported benefit of the approach is its reliance on the acknowledgement of contribution at the individual level, which leads to trust and organizational alignment. Since the method discusses concrete successes and lends itself to cross-industrial social activities, it is supposed to be enjoyable and natural to many managers, who are thought to be naturally social people focused on the bottom line. Appreciative Inquiry was developed by David Cooperrider of Case Western Reserve University. It is now a commonly accepted practice in the evaluation of organizational development strategy and implementation organizational effectiveness tactics. The Appreciative Inquiry utilizes a 4-stage process focusing on: (1) DISCOVER: The identification of organizational processes that work well. (2) DREAM: The envisioning of processes that would work well in the future. (3)DESIGN: Planning and prioritizing processes that would work well. (4) DELIVER (or CREATE): The implementation (execution) of the proposed design. Sensemaking is the process by which people give meaning to experience. While this process has been studied by other disciplines under other names for centuries, the term "sensemaking" has primarily marked three distinct but related...

...Vuh, we can see that the ability to speak and reason defines humanity. Speech is first introduced as just existing when the world had just begun. Any form of life had not existed except for the sea. Then the myth illustrates the power of speech when the Gods create the earth from just their words after talking and pondering together. The ability to speak has great power and is something that the Mayans felt important in their culture. The story then goes on as the Gods create animals as the first living beings. . However, these living beings were incapable of human thought and the gods expressed their dissatisfaction by saying to the animals, “You shall be replaced because you were not successful.” This begins many experiments by the Gods for the perfect human being. After being disappointed in the creations of animals, mud people, and wood people, the Gods finally create human that are capable of human thought. These humans were created by maize and water which are the necessary nutrition to sustain life for the Mayans. However these humans become another “mistake” for the Gods when they are asked to speak. The relationship between speech and reasoning is distinguished when they rename the Gods as “grandmother” and “grandfather.” The ability to give name to things show that the human has wisdom and power that makes them equal to the Gods. As a result of this fear, the Gods state “What now can be done to them so that their vision reaches only nearby, so that only a little of...
