...Vincent Marziano MUS 361U Dr. Bluestone 5/16/2013 841 words #20 Bob Dylan Highway 61 Revisited Can words describe the amount of sound that came out the speakers after playing Bob Dylan’s Highway 61 Revisited? The many sounds that make up this remarkable piece of what one could only describe as artwork is a phenomenal mix of instruments and vocals to produce a sound that is of no other. Dylan combines everything from a simple harmonica (which he makes sound anything but simple) all the way up to electric guitars, drums, acoustics, tambourines, banjos and even what sounds to be like a Kazoo in track 7! His background falls under influences coming from the blues with an emphasis on delta blues, and a strong country back ground as well. He ties these older sounds together with the new sounds of today’s rock and roll to create even flowing and cohesive piece of work. His music is made for the youth and even in a time when folk and country music is something we would relate to our parents, his music brings out a young vibrantness that no person, old or young, could ignore. His overall CD encompasses many mixed emotions. Dylan seems to incorporate personal stories of his own life along with random stories which when combined produce songs of happiness as well as desperation to the modern world. His CD doesn’t carry a main story line, and in fact really sounds like a mix of random feelings and emotions that he kind of slapped together into one cohesive motion. His first...

...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...

...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...

...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...

...Loyalty demonstrates to be a helpful asset to the family’s life. The earliest example is the grandfathers consistency during his life his wife “he has always been loyal to his blood” (Macleod 35).. Since this common ideal is shared by all, it is proven to the family to become more unified and because of this share more memories as well as makes new ones. The importance of family ties and always keeping in touch with your roots is one of the reasons that the acts of loyalty ultimately help. Alexander Macdonald’s eldest brother Calum is an example of “all of us are better when we’re loved” (34). His aggressive nature derived from his unstable history causing him to live in the past is incapable of moving on. During this desolation Calum’s brother Alexander consistently supports him with his intangible love and support. Although Calum puts his life on hold, Alexander’s positive attitude and loyalty he makes no progress. Another example of how loyalty helps, is the dog with its companionship in a moment of tragedy, attempts a heroic act. People may not fully appreciate the capability caring and imitating this immense quality...

...ANDREW WYETH Away from the art scene in New York and Paris during the 1930’s, in the small town of Chadds Ford, Pennsylvania, a regionalist painter depicted his surroundings and the people that took part of his life. His name was Andrew Wyeth, also referred as “the painter of the people” who became a renowned underrated artist in the United States during the 20th century. Andrew Wyeth (1917-2009), the youngest of five siblings, was born into a family of artists who shared a love for nature and poetry. His father was the illustrator and artist Newell Convers; his brother, Nathaniel Wyeth was an inventor and his sister Henriette Wyeth Hurd, an artist. He fathered Nicholas Wyeth and Jamie Wyeth, both artists as well. Andrew’s childhood was shadowed by his respiratory problems, which forced him to be...

...The Roaring Twenties, Jazz Age, and the Golden Years were names synonymous for the 1920’s. The economic boom after World War 1 liberated the American people resulting in an increase in population who were happy and worry-free. This inspired artists and writers to be creative. Some stories helped people dream and conquer all but others showed the hardships people faced. The Algonquin Round Table Journalists, editors, actors, and press agents met on a regular basis at the Algonquin Hotel in New York began meeting in June 1919 and continued fro eight years. They contributed to hit plays, bestselling books, and popular newspaper columns. They shared admiration for each other’s work. These people had very high standards and they were very outspoken, outrageous, and they often quoted one each other. This group began to fade away as The Great Depression neared. They were a great example of American artists F. Scott Fitzgerald wrote several stories with The Great Gatsby being his most famous work. This story helped inspire people to believe that they could dream anything and achieve it. Fitzgerald’s stories were mainly about people becoming very successful in the social and financial worlds, but they did not share the same prosperity and the morals. He also wrote This Side of Paradise. Unfortunately, not all books were happy and motivating. Several writers wrote about the hardships people faced in the 1920’s. In Alain Locke’s The New Negro, Locke wrote about the...

...Jordyn Byers HST 447 03/07/13 The Porfiriato Judas at the Jockey Club BY: William H. Beezley The Porfiriato The theme of the 19th century was “change,” and countries around the world had begun to see revolution and modernization. Societies began to shift from tradition and old beliefs were replaced with new ones. However, an adjustment that extreme was sure to present it’s fair share of opposing opinions from the countries people. Whereas Mexico was no exception, and likewise to other revolutions, conflicting political views had divided the country. However, having just ended a war, the country was left in a period of belated reform and was in need of rapid industrialization and urban growth to ensure the rest of the world did not leave them behind. For instance, in William H. Beezley’s Judas at the Jockey Club, the most notable examples under the rule of Porfirio Diaz between 1876 and 1910 are explained, amid Mexico’s political and social transformation. Though these transformations ultimately led to Mexican modernization, the reform came at the expense of its people. Whereas the nation’s inhabitants had split into two groups, the wealthy, who favored reform, and the poor, who held traditional methods close. This domestic conflict only made the pressure to implement change more difficult as it became a necessity for survival in the new world. Diaz’s plan to synonymously restore order and change to a broken country thrived upon...

...Eager 1 Tabitha Eager Ms. Kazlauskus FHE 5 17 December 2013 Isolation Longing and loneliness can be overwhelming even when surrounded by other people. In Steinbeck’s novel Of Mice and Men, he illustrates how the alienating actions of the migrant field workers cause the characters to become isolated and withdrawn, leading to desperation and extreme loneliness. Steinbeck’s story takes place in the depression era 1920s when racial discrimination and discrimination against the mentally challenged was more of a norm than an exception to the rule. Characters in this novel such as Crooks and George share the same longing and desire to not feel so alone and misunderstood. Each have been alienated by those around them for the differences they can not control; the color of their skin, how they choose to live their lives and the secrets that they covet, that alienation has led to isolation and the inevitable loneliness that follows. Crooks is the black stable hand that is caring, empathetic and intellectually sharp, however he has grown defensive and bitter from the years of segregation. In the 1920s being black meant that you were not treated as equal. Crooks was not permitted to bunk, eat or generally socialize with the other field workers. Steinbeck depicts this when Lennie enters Crooks’ room one evening “smil[ing] helplessly in an attempt to make friends” as his giant body filled the door (Steinbeck 68). From years of being shoved aside Crooks had built up a wall of defense, he responded...

...in a way that more closely resembles our everyday lives. In many ways, color takes on a life of its own, serving both realistic and symbolic functions. For example, color is used boldly for the first and only time in the final scene of the film [02:03:45]. Jake drives into Chinatown and passes two neon sign, one of which is only half-lit. This place is foreign an unkempt, a reminder of the life that Jake left behind. Throughout the rest of the film, color is used carefully and in moderation to reflect both the physical and political setting. Browns and yellows dominate in nearly every scene. This color scheme establishes and intensifies this idea of desolation caused by the drought. Warm colors are often used to convey warmth and safety, but in this situation, they signal the exact opposite. Color itself is deceptive--a quality shared by many other sources throughout the...

...unencumbered… from the stifling…. world of abstraction, security and material excess, a world in which he felt grievously cut off from the raw throb of existence.” The contrast between the words ‘security’ and ‘stifling’ creates a juxtaposition that symbolises the contrast between Alex’s perception of the world in comparison to others’. This moreover exposes the motivation for Alex’s pilgrimage as being one of rebellion, escapism and freedom. The dark and blurry scenes of Alex travelling through metropolitan regions in contrast with the vibrancy and light of the natural environments he visits, furthermore represents his assessment of both atmospheres and sets the tone of each scene. Ovid’s description of Tomis being “a place of utter desolation… like the inside of my head “ expresses that his environments are symbolic of his mental state. This also illustrates his transition from a world of comfort and security to a world of new experiences and perceptions. The purpose of this symbolic imagery is to convey to the audience the important innate connection man has to mother-nature. Contrary to Into The Wild, An Imaginary Life suggests that the concept of identity is strongly molded by societal ties. It is conveyed that one’s impact and role in relationships and the broader community gives substance and meaning to oneself and life. This becomes apparent in Ovid the poet’s journey when he reveals in his journal that he has been exiled from his Roman society, and cast out to live...
