Operating Systems and Networking - Coursework Example the following fields: opcode: 8 bits ra: 6 bits rb: 6 bits rc: 6 bits rd: 6 bits where ra, rb, rc, specify three input registers and rd specifies one destination register. If there is a single register file to store the identifications of all registers, how many registers could there be in that register file? 1.3. A processor has 24 registers, uses 8-bit immediate, and has 36 different instructions (corresponding to 36 operation codes) in its instruction set. These 36 instructions are classified into 4 types as listed below: Assume that the ISA requires that all instructions be multiple of 8 bits (1 byte) in length, and the operation codes (opcodes) are fixed length. Answer the following questions and write down the calculation steps involved. Type C: 6 bits of the operation code, 5 bits for the source register, 8 bits of the immediate, and 5 bits of the destination register. This totals to 19 bits. These are rounded up again to 24 bits. 24 bits are equivalent to 3 bytes. Therefore 3 bytes are required to encode type c instruction. The pipelining diagram is used to show the execution of a series or a sequence of instructions of processes of a computer. In the diagram, the sequence of instructions is shown vertically; that is from the top to the bottom. As for the clock cycles, they are often shown in the horizontal; that is from the left to the right. Each and every instruction is divided into its component stages. There are 3 instructions. Suppose a non-pipelining processor took 50 Nano seconds to process one instruction, and then it would take 3 * 50 = 150 Nano seconds to complete all the instructions. However when pipelining is used, we instead have 4 segment pipeline with a clock cycle that takes at least 10 Nano seconds approximately. 2.2. Suppose we have a slightly more complex program with data dependency and branches. Assume that in the case of branching, the instruction following a branch is always executed. Note that a conditional branch

Trends in healthcare services - Essay Example This option is optimal because it enables the government to collect adequate funds from the workers for the national health insurance program. In addition, this platform is fair to all the groups of workers considered as it applies the charges as a percentage of their payroll; hence a worker contributes an amount relative to his or her salary. This also makes the platform fair for all (Diamond & Vartiainen, 2012). Currently, there exist different types of health insurance plans that individuals can opt for in a quest to secure health insurance. In addition, there also exist a number of health maintenance organizations, capitations, as well as preferred provider organization within the health insurance market. These different platforms of health security and insurance have a significant effect on the trends of healthcare services today. For one, these aspects have made it possible for more people within the population to be in a position to afford and access quality medical healthcare services despite their income levels, especially considering the high cost of medical services within the United States. In fact, the US is one of the developed countries that has the highest or the most expensive health care program in the world, thereby subjecting a great portion of its populace to poor health care services due to unaffordability (Feldstein, 2011). Nowadays, a health insurer has to consider a number of factors, on both the economic as well as the societal platforms that affect the pricing and demand of health care services within the market. Health insurance exists in order to provide the people with access to quality medical healthcare. However, the people need to afford these insurance policies in order to be in a position to subscribe to them appropriately. Therefore, in setting the price for these health insurance programs, the insurers need to consider the income levels of each

Child Labour in Third World Countries Essay Example | Topics and Well Written Essays - 3500 words

Child Labour in Third World Countries - Essay Example In 2002, the U.S. Congress passed legislation ordering the Department of Labour's Bureau of International Labour Affairs to study the relationship between education and military expenditure in countries where child labour is recognized to be particularly common. The word child labour in general refers to any economic activity carried out by someone not above the age of 15. Not all work done by children is harmful or manipulative. Child labour does not normally refer to part-time work after school or rightful internship opportunities for young people. Nor does it refer to adolescent people helping out in the family business or on the family farm. Rather, the "child labour" of concern is general employment that prevents children from getting education, and which is often performed under conditions dangerous to the physical and mental health of the child. The International Labour Organization, or the ILO, defines child labour as "some types of work" done by children under the age of 18. The ILO also says that child labour includes full-time work done by children under 15 years of age that prevents them from going to school (getting an education), or that is dangerous to their health. More complete definitions of what child labour is in regard, age restrictions, job types, and exceptions can be found in convention 138, convention 182, and the convention on the rights of the child. (Child Labour) Other sources and organizations disagree on what child labour is. Some utter that it is merely perilous work or work that obstruct with a child's education, while others are broader and include any work done by children working for compensation. Some organizations, such as UNICEF draw a line between child labour and child work, which can consist of light work done by children above the age of 12. Child Labour in the Fashion Industry There are no reliable statistics on the rate of child employment in any particular economic activity, including the fashion industry. Most information on child labour in the garment industry comes from eyewitness accounts, studies by non -governmental organizations (NGOs) and academicians, reports by journalists, and studies by the International Labour Organization (ILO). Unreliable information obtained during the preparation of this report indicates that in some of the countries examined, fewer children could currently be working on garment exports for the U.S. market than two years ago. A striking example involves Bangladesh, where great numbers of children worked in garment factories as lately as 1994. Worldwide media attention and intimidation of boycotts and cancelled work orders led to the dismissal of thousands of child workers from the garment sector unfortunately without any backup support for them. Thus, it is possible that in the lack of government programs to help the children, the abrupt discharge of child workers can put them in danger, rather than protect them. More research is required so that governments, industry, international organizations, and others apprehensive of the welfare of children are better capable of designing suitable programs. It is obvious, though, those local and national assurances to collective and free education for children are instant and optimistic steps which can and should be taken. One cause for any possible downward

Psychology And How It Affects The System Of Referencing Essay Example for Free

Psychology And How It Affects The System Of Referencing Essay Cataloging is an olden time procedure that is made to arrange the collection of books within libraries. Of course, since libraries are considered to have a large collection of reading materials, arranging them into categories helps in the process of researching for the students or plain readers alone. However, this procedure of arranging the files and taking notes of the information with regards a certain book takes much time and effort from the librarians that they are already incapable of doing the primary responsibility that they should be addressing in their profession, assisting the readers. Today, the development of technology aides in libraries have created a radical change within the systems of arranging the files as well as redefined the role of librarians in completing the tasks appointed for them to finish. Technological changes are indeed good. As for this matter, the changes of the procedures taken into consideration by libraries have indeed radically changed the ways by which the librarians tried to complete their duties to their profession,. The existence of computer-based programs also made several files in the local libraries available online making it more convenient for readers to utilize. More than that, it could be noted that the digital based Operating System that is used in public libraries have made it easier for readers to find the actual resources that they need for their researches becomes highly possible and efficient for the users. Yes, the impact of technology in library activities as well as within the procedures of referencing could indeed be considered one of the most successful applications that is made and presented by today’s modern technology. Of course, with the massive overflow of informations through the publication of several reading materials, filing them up in a way that readers would have them through easier access today is beneficial. This is also true in terms of psychological referencing. IT is undeniable that both traditional and modern technological approaches make the psychological references more utilized for studies and assessment procedures for present researches. Psychology too interacts with the different approaches used today in referencing systems. Most often than not, the systems carry the fact that there are certain measures that needs consideration in terms of the acceptance of the human behavior with the referencing systems that are concerned with systematically placing references for basis of studies. Because of the utilization of technology, it is undeniable that the major sources on derived from psychological readings had primarily been improved. Both the ideas and the authors are carefully jotted down in researches with ample accuracy that the studies passed about psychology are then considered to be highly authoritative and validated in terms of sourced references.

The Disease to Follow Is a Greater Threat :: Journalism Epidemics Health Essays

The Disease to Follow Is a Greater Threat This year, our nation faced a pair of crises: war and pestilence. Even as our brave men fought for America on Germany soil, an invisible and perhaps more deadly foe took hold in our nation and around the world. Our nation's hospitals face a drastic shortage of staff and space to accommodate adequately both the wounded soldiers who have returned from the war and our civilian population who have fallen victim to influenza. This was a consequence that we could not have foreseen. It is suspected that the origin of this great epidemic may have been Boston, considering that it is one of the busiest ports in our nation. From there the infection has spread throughout the New England area and reached areas as remote as California. Although this disease is called the "Spanish Influenza" it has spread beyond Spain, Europe and America. Cases from as far as the Orient and even Africa have been documented and verified. Clearly, this is no ordinary flu. However, I believe that this flu is extraordinary not only in its destructive nature, but in casting a legacy of distrust for science amongst the general populace. In Sierra Leone the flu was brought from Europe and become a deadly epidemic. A report claims that as many as 1,000 individuals had died there in a single week. Furthermore, the shortage of food in the region further execrated the problem. Strangely, the disease did [not] just claim human victims. There were even reports in Sierra Leone of monkeys and other primates who became stricken with the flu. (NY Times) The flu was perhaps hardest on our troops fighting abroad. Not only did they have to contend with the German infantry's relentless machine gun fire from the trenches, but they also endured some of the harshest conditions in the history of war. Here at home, we could easily put on a mask and avoid those who are infected hoping that we could avoid this virulent disease. But our brave fighting men could not. In the trenches of Germany, they had more to worry about than simply catching a cold. Their survival often depended on the cover fire from their nearest comrade, sick or not. Needless to say, the Americans were not the only party affected by this illness.

Don DeLillo Essay -- Biography Biographies Essays

Don DeLillo Throughout the twentieth-century, humanity has had the privilege of reading the works of many fine authors. Authors such as Toni Morrison, James Joyce, and even Robert Pinsky all come to mind. But when one thinks of the most prolific writers in the twentieth century, Don DeLillo is certainly one of them. Born in New York City in a small Italian neighborhood in the Bronx, DeLillo was destined to be a writer. He attended Fordham University where, upon graduation, he worked for an advertising agency. Dissatisfied, he left the agency in 1964 to begin working as a freelance writer. As a freelance writer, sustaining a living on a mere two thousand dollars a year. DeLillo wrote on a vast amount of subjects including computers and furniture and began to work on his first novel, Americana. It was his first published novel that took him nearly four years to finish. Although DeLillo encountered many obstacles during work on Americana, he persevered overcoming "constant interruptions to make money" (Charters 428). It was during this time that DeLillo knew that he was a writer. Other novels were born after Americana. End Zone, which was written shortly thereafter, also achieved significant success. During the next twelve years, DeLillo wrote five more novels including the breakthrough White Noise that was published in 1985 and for which he won the coveted American Book Award. Other novels followed including Libra in 1988 and the 1991 debut of Mao II, a novel about terrorism and political violence which won DeLillo the PEN/Faulkner Award for fiction. In addition to his novels, DeLillo also wrote plays, short stories and essays on various contemporary subjects. In 1997, however, DeLillo would prove to the writing world tha... ...and research what is going on in their domain. In addition, Underworld is a novel that encompasses loose-knit fabrications of the tensions, preoccupations, and manias of modern America. Whether they are about the Cold War or our love for the media and its flattening of character, we as a society rely on sources that are not relevant to our own thinking. This was DeLillo’s ultimate goal when he wrote Underworld. The ability to look at things and rely on one's own source of thinking to interpret what they mean is important to DeLillo. He encourages his readers to allocate their resources and find out the validity in their world and the problems that could come into it. Works Cited Charters, Ann, ed. The Story and Its Writer.

American Mafia

According to Wikipedia the free encyclopedia, The American Mafia especially Five Families has its origins in Italian Cosa Nostra. The American Cosa Nostra underwent many changes at the hands of Black Hand gangs around 1900s, Five Points Gang during 1910s and 1920s in New York City and Al Capone’s Syndicate in 1920s in Chicago. Two factions of organized crime emerged by the end of 1920s leading to Castellamarese war for gaining control over organized crime in New York City. Murder of Joseph Masseria, leader of one of the factions ended the war uniting the two factions.First leader of the American Mafia Salvatore Maranzano established a code of conduct, â€Å"family† divisions and structure. He also established certain procedures to resolve disputes but was murdered within six months. Charles â€Å"Lucky† Luciano took over the reins and set up a â€Å"Commission† consisting of bosses from six or seven families for managing their activities. According to Bind er, Jim Colosimo or â€Å"Big Jim† was considered the most powerful gangster and led a multi-ethnic group, with Italian, Jewish, Irish, Greek and other members. In May 1920 he was probably shot dead by â€Å"Frankie Yale under contract John Torrio.† John Torrio took over and united major local gangs dividing the liquor business in Chicago city to a stable state and profitability. The other major gangs during this period in Chicago were North Siders led by Dion O’Banion, the Guilfoyle gang, the Gennas in Little Italy, the West Side O’Donnells, the Druggan-Lake gang, the Saltis-McErlane gang and the Sheldon gang. Torrio under the guidance of Capone took over brothels in Cicero and managed the largest area covering the South Side and major suburbs occupying the south and west of the city.Problems started when a gang tried to increase its profits by not following the agreement strictly and entered neighboring gang’s territory. Friction between Gennas a nd the O’Banion gang led to the murder of O’Banion in November 1924 starting off prohibition gang wars. The Sheldon gang, the Gennas, the Druggan and Lake, the Guilfoyle and later the Circus Gang were all allies of Torrio-Capone. Chicago Heights joined Capone in 1926 and controlled Joliet and major areas east of Indiana and south of Chicago. Torrio was succeeded by Al Capone in 1925.Gennas under Hymie Weiss surrendered after their leadership was attacked by North Siders and the Gennas rackets such as Unione Siciliana were taken over by Al Capone appointing Tony Lombardo as Unione president. The West Side O’Donnells joined ranks with Capone in 1926 after a short lived gang war. Similarly Sheldon gang too joined Capone after Danny Stanton left the town. Gang wars continued for several years and North Siders lost Hymie Weiss in October 1926, nothing remarkable was noticed until the St. Valentine’s Day Massacre in 1929.Now let us consider organized black gang s during this period run by Italian, Jewish and Irish gangsters operating from Harlem, New York and a few loosely run black gangs concentrated primarily on policy and lottery gambling, prostitution and drugs. Bell stated that over 200,000 blacks returned after World War I to Harlem expecting better pay, better housing and equality. But they realized very soon that whites had not changed and found some of the worst low paying menial jobs such as that of janitors, bootblacks, cooks, houseboys and baggage handlers.They were paid very less compared to a white person doing the same work. The housing situation too was worst; Harlem an overcrowded and segregated community accommodated more than 250,000 citizens in 50 blocks long and 8 blocks wide area with more than 5,000 people staying in one block. The people were compelled to sleep in shifts. Blacks suffered the most with Racism, race riots and labor riots being the order of the day. Things moved from bad to worse with the passage of 18 th Amendment to the constitution banning sale of alcoholic beverages by the Congress on January 20, 1920.Establishments primarily depending on the sale of these products (alcoholic beverages) were compelled to down the shutters across the nation. These developments marked the beginning of the infamous Roaring Twenties – one of the country’s darkest periods when the mob, the crooked politicians and the gangsters ruled. Taking advantage of the fact that consumption of alcohol was a part of American culture and people could not stop drinking due to prohibition, the mob and the crooked entrepreneurs illegally transported the alcoholic beverages from the Canadian border and at times even manufactured beer and liquor.â€Å"The overt exclusion of blacks from the nation's economic, social and political processes only served to foment alternative means toward becoming a part of established idealized factions. † Blacks were suppressed to the maximum possible extent by den ying good jobs, influential political positions, advanced education, nice homes, equal social treatment and benefits. Thus most of the black Americans took to illegal means to compensate for the economic denials.Black crime was independent initially with traditional thievery, gambling, prostitution and robbery, but later two key factors Bolito (the numbers game) and drugs led to evolvement of organized crime. Bets could be placed from any where such as parlors, bars, restaurants, pool halls, barber shops, drugstores and even from their homes, more than 800 runners or bet collectors hurried places to collect and place bets on behalf of customers in 30 policy banks. The policy bankers became the richest and started extending loans and finance to Harlem residents, which the blacks could not expect from whites operated financial institutions.The big time number operators included James Warner, Stephanie St. Clair, Casper Holstein, Wilfred Brandon, Jose Miro, Joseph Ison, Masjoe Ison and Simeon Francis. By 1928 the numbers game became most profitable and the arrests on this count also increased. Profits were reported to the elected representatives through police officials and these corrupt elected politicians had strong links with mob’s syndicate led by white gangsters. â€Å"Corruption ran throughout New York's law enforcement, legal and political systems, including bondsmen, high-ranking police officials, judges, lawyers and politicians.† To protect themselves the night clubs, businesses, bars, pimps, whores, gamblers, bankers and number runners started paying huge kickbacks. Democratic Party boss in Manhattan, James J. Hines had links with mobster and beer baron â€Å"Dutch† Schultz. Schultz and fellow Murder Inc. gangsters â€Å"Lucky† Luciano, Frank Costello, Owney Madden, Bugsy Siegel, Joe Adonis and Meyer Lansky started taking over Harlem’s numbers racket. Short gang wars that erupted due to taking over and syndication led to an estimated 40 murders and 6 kidnappings. By late 1928 a total of 20 policy banks remained out of 40 and most of the bankers retired mysteriously.Dutch Schultz was in total control and called â€Å"King of Harlem Bankers† From the discussion above it is clear that organized crime had flourished in American society basically due to prohibition which was in vogue from 1920 to 1933 and every affluent individual was either directly or indirectly involved in illegal activities such as illicit liquor trafficking, prostitution, maintenance of brothel houses and having ties with mafia bosses. It is now clear that removal of prohibition led to a reduction in one of the evils i. e. , illegal liquor trafficking, but other illegal activities do continue carried out even to this day.References Cosa Nostra.
