Processors - Essay Example PowerPC is largely based on IBM's earlier POWER architecture, and retains a high level of compatibility with it; the architectures have remained close enough that the same programs and Operating Systems will run on both if some care is taken in preparation; newer chips in the POWER series implement the full PowerPC instruction set. The original POWER microprocessor, one of the first superscalar RISC implementations, was a high performance, multi-chip design. IBM soon realized that they would need a single-chip microprocessor and to eliminate some POWER processor instructions to scale their RS/6000 line from lower-end to high-end machines, and work on a single-chip POWER microprocessor, called the RSC (stands for RISC Single Chip) began. In early 1991 IBM realized that their design could potentially become a high-volume microprocessor used across the industry. IBM approached Apple with the goal of collaborating on the development of a family of single-chip microprocessors based on the POWER architecture. Soon after, Apple, as one of Motorola's largest customers of desktop class microprocessors, asked Motorola o join the discussions because of their long relationship, their more extensive experience with manufacturing high-volume microprocessors than IBM and to serve as a second source for the microprocessors. This three way collaboration became known as AIM alliance, for Apple, IBM, Motorola. In 1991, the PowerPC was just one facet of a larger alliance between these three companies. On the other side was the growing dominance of Microsoft and Windows in personal computing and of Intel processors. At the time, most of the Personal Computer industry was shipping systems based on Intel 80386 and 80486 chips, which had CISC architecture and development of the Pentium Processor was well underway. The PowerPC chips was one of several joint vent ures involving the three, in their efforts to counter the growing Microsoft-Intel dominance of personal computing. The PowerPC is designed along RISC principles, and allows for a superscalar implementation. Versions of the design exist in both 32-bit and 64-bit implementations. Starting with the basic POWER specifications, the PowerPC added some features, including: Support for operation in both big-endian and little-endian modes - the PowerPC can switch from one mode to the other at runtime. This feature is not supported in the PowerPC G5. Single-precision forms of some floating point instructions, in addition to only double-precision forms. Additional floating point instructions at the behest of Apple. A complete 64-bit specification, which is backward compatible with the 32-bit mode. Removal of some of the more esoteric POWER instructions, some of which could be emulated by the Operating Systems, if necessary. A paged memory management architecture which is used extensively in server and PC systems. Addition of a new memory management architecture called Book-E, replacing the conventional paged memory management architecture for embedded applications. Book-E is application software compatible with existing PowerPC implementations, but requires minor changes to the Operating Systems. Operating Systems that work on the PowerPC architecture are generally divided into those which are oriented towards general-purpose PowerPC systems, and those oriented towards the embedded PowerPC systems. A 64-bit PowerPC application

This is followed by the analysis of the quality of service of the hotel. The aim of this study is to understand in-depth the operations management of the five star hotel and to make appropriate recommendations. 2. Research Methodology: The research methodology includes both primary and secondary research. The primary research was conducted by visiting the premises of the hotel and directly observing the operations management at the hotel. It also included a survey of about 20 guests of the hotel. The secondary research was done by delving into books, academic sources and other reports concerning the hospitality sector and operations management. The data and information collected were analyzed qualitatively and quantitatively. 3. Brief description of specific features of the hotel which have a bearing on my analysis and were not included in the description given: The areas of service quality, costs and room occupancy were not mentioned in the description provided. There was also no mention of the supplies used by the hotel. These areas have a special bearing on my analysis. A customer survey was also undertaken. The recommendations are based on this survey. 4. General Analysis of the hotel: 4.1 Design (product and facility): Product design is one of the critical issues of operations management. It is product design that determines the characteristics and features of a product and how well the product functions (Dyson, Robert G, 2000). Facility design determines the capacity, location and layout of the production or service facility (Krajewski, L.J., and L.P. Ritzman, 1993). The five star hotel is located in

The Influence of Police Culture

The Influence of Police Culture In order to appropriately address the topic of discussion, firstly, it is important to understand what is meant by the concept police culture. After establishing its definition, it then becomes a task to assess whether police culture does indeed have a negative influence on the way the police work as an institution or whether it merely ensures that a certain level of consistency in achieved in terms of the way officers conduct themselves in their daily working environment. The term police culture has in itself been a topic of some discussion with sociologists being divided over what the definition should and should not include as there isnt an established, concrete definition of the concept. For example one contributor who has attempted to rectify this problem is Reiner (1992) who describes it as the values, norms, perspectives and craft rules which inform police conduct (Reiner 1992 quoted in Loftus 2009: 3). Whereas another definition comes from Manning (1989) who defines it as accepted practices, rules, and principles of conduct that are situationally applied, and generalised rationales and beliefs (Manning 1989 quoted in Loftus 2009: 3). Although these definitions dont appear too different at first glance, there is in fact a clear distinction between the two that should and must be made mainly the fact that Manning stresses that such principles of conduct are situationally applied, which of course suggests that police culture is not always necessa rily influential to an officers conduct. Some officers can and do hold a certain level of professionalism when taking to the streets and any values which may corrupt such professionalism remains behind closed doors in the company of their colleagues only. Yet Reiners provided definition suggests that the police culture remains with the police officer when they take to the streets and he/she then enforces the informal rules which have been established with their fellow colleagues, which generalises that all police officers act in accordance to the police culture . However what must be taken from both definitions is that there is reason to suggest that there is a network of a shared set of norms and values within police forces which could potentially have an effect on how they operate in a working environment. What also must be stressed is that there is also a distinction between the terms police culture or cop culture (as its otherwise known) and canteen culture which is another concept which crops up time and time again in countless criminology texts. Canteen culture, as mentioned by Waddington (1999), is understood to be the norms and values held by police officers whilst off-duty, whereas police culture is the norms and values which are expressed during the course of their occupational lives (Waddington 1999 cited by Crank 2004: 16-17) Newburn (2007) also makes this a key point by explaining that there is a common tendency to assume that what police choose to say and how they choose to act when off-duty is not only indicative of how police officers think, but also how they act in public. (Newburn 2007: 216) Yet Waddington has a problem with such assumptions, as he claims that this is not the case all of the time. The way officers act and the views they hold whilst off-duty, whether in the pub with friends or work colleagues is but a safety valve to release the pressures of the realities of life as a police officer (Waddington quoted by Newburn 2007: 618) Such an argument claims that in experiencing somewhat controversial views outside of the working sphere, a person is opened up to new perspectives which sociologists such as Waddington would argue helps to avoid them from being over-exposed to a particular ideology which could then influence the way in which they carry out their duties. But what also must be considered is just how valid Waddingtons argument actually is. Yes, of course in some instances exposure to different attitudes and values can be beneficial to an officer in terms of becoming more aware of the possibility of potential new threats, but there are also some officers who would then, due to any extreme views which they may have been subjected to, may target an individual or a group of people because of the stereotypes attached to such persons and not because of genuine suspicion. Police culture, it is claimed by Reiner (1992) has many characteristics in which it can be identified with, with suspicion being just one of them. Suspicion is an absolute necessity in the police force as it is suspicion that helps the police prevent crimes from occurring and therefore everyday working experiences encourage officers to generalise people into particular labels, whether or not this is a legitimate way to suspect possible offenders (Reiner cited by Newburn 2007: 618). Unfortunately there is a strong link between suspicion and ethnicity, with ethnic minorities suspected to engage in criminal activity more than people of white ethnic origin. The 2005/2006 Home Office statistics relating to police searches provide a great example for this. In interpreting the results of stop and search practices, 15.4% of the entire UK Black community were stopped under the Police and Criminal Evidence Act 1984 (PACE Code A) in comparison to only 1.6% of the entire white population. This d iscrimination however doesnt just end with the police; it branches out into other areas of the criminal justice system such as the prison service. Genders Player in (1989) claimed that prison officers sometimes use active stereotypes and labels to help order their working environments by predicting inmate behaviour in order to maintain authority at all times. Prisoners within the ethnic minority demographic were perceived as having a chip on their shoulder, as they felt they were being victims of racial persecution and thus the officers paid more attention to monitoring their behaviour. Arguably the most problematic characteristic of a police culture in terms of the impact it has on police and community relations is the element of racial prejudice. One of the most notable examples of racial prejudices derives within the Macpherson Report (1999), arguably the most notable report in criminology, which followed the death of black teenager Stephen Lawrence. The report found that the police were institutionally racist after discovering that police were ignoring crucial evidence to the investigation and were displaying discrimination in the interviewing process of suspects suggesting that it was black on black crime, despite Lawrences friend (an eye witness) being adamant that it was a racially motivated murder. Despite the findings of the report and the provisions set out to try and avoid the recurrence of racial controversy within the police, there is evidence to claim minority ethnic recruitment still remains low and there are still continuing problems in terms of pol ice relations with ethnic minorities (Croall 2011: 221-222). The aftermath of the Macphereson Report proved that institutional racism was still rife in police recruitment centres, as four years onwards a BBC documentary titled Secret Policeman was aired which centred on the police recruitment centre, Bruche which was located just outside of Warrington. Consequently after the footage of the documentary went public, the centre was forced to close so as to not further damage the reputation of the police. New police training systems were also introduced nationwide to try and expel racism from the police force as a result of the documentary. (The Observer 2004) How officers are socialised is of another great significance. The next characteristic of a police culture is the degree of solidarity, and it is this element which although is reinforced in numerous police forces, it is an aspect which is initially developed between candidates during the recruitment stages. Due to the intense nature of the job including the long hours which officers are required to work, the intensity of some of the work and the expectation of being the ones to prevent social decline, officers are encouraged to bond strongly and they learn to rely on one another, and as such tend to develop an us-against-them attitude. This resulting mentality, in some situations, leads to not officers making pacts with one another in which they agree not to grass on fellow officers for any discrepancies that they might have witnessed whilst on duty. This is more commonly known as The Blue Code of Silence. Just like any other subculture, in order to ensure cooperation and commitment to the Blue Code, a tribal value system is implemented which makes police culture sort of like a family structure in which members of the system will receive emotional support and security from the other officers upon requirement. Several police departments worldwide have been found to have followed the Blue Code, probably most notably was a New York police department which the Mollen Commission reported were to be covering up infringements of their officers. In such case where an officer was to break the Code, then his/her reputation and essentially his career too would be ruined as he/she would then be ostracised and labelled a whistleblower and thus it is the threat of this tarnished reputation that encourages the officer to obey the unwritten rules. (Loftus 2009: 14) Accusations of excessive force by members of the police force are far from uncommon, particularly in America. And it is the use of excessive for which Manning (1970) claims is a perfect example of police culture and how it can have a negative influence on the way officers carry out their duties. (Manning 1970 cited by Crank 2004: 107) However, excessive force is not detected in all cases. Victims of police brutality may feel that the odds are stacked against them in filing a complaint to an officers superiors and are thus reluctant to do so and may feel that even if a complaint is acknowledged and results in a court case, the judge and jury would overlook excessive force as the perceived perspective would be that the victim shouldnt have gotten his/herself in a position in which the use of force was needed in the first place and thus the consequences of their anti-social behaviour was deserved. Yet with that said, there are of course examples where the victim of police brutality are non-deserving of such treatment and thus the police force as a whole have come under criticism despite it being a minority of officers that participate in such excessive violence. For example a British police constable, PC Simon Harwood, was charged with the manslaughter of Ian Tomlinson during the G20 protests in 2009. Tomlinson was finding another route home after his usual route was blocked by the protests when he was struck by PC Harwood with a baton and then pushed to the ground Tomlinson fatally collapsed and an autopsy revealed the cause of death was a heart attack, which the actions of PC Harwood where no doubt a triggering factor. PC Harwood was acquitted of manslaughter, which only strengthens the argument mentioned previously that the courts are sympathetic to the police when the question of reasonable/excessive force is raised. However, it must be stressed that many police forces do have provisions in place to deal with any complaints of unacceptable behaviour regarding their employees in which inquiries will be carried out and, if found guilty, the officer in question may be reprimanded, suspended or permanently dismissed depending on the circumstances. Also, as in the case of PC Harwood they may also, if necessary, face criminal prosecution or at the very least face a civil hearing if the victim wishes to sue for damages caused by the officers ill-considered actions. But how are the police able to get away with these kinds of infringements? Again, it all relates back The Blue Code of Silence. As already mentioned earlier in the essay, officers of some police forces claim ignorance of any wrongdoings of their work partners and in some cases, they testily which is typically an American slang term for when an officer gives false testimony in court. Relating back to the tribal values, not participating in activities such as testilying would lead to an officer being shunned and sometimes even harassed to the point of retirement as they arent assisting their family members, in effect betraying their own kind. In 1994, the Mollen Commission found that some officers within the NYPD fabricated crucial documents such as arrest reports and warrants and some officers were found to have falsified witness statements for the purposes of manipulating the jury as they felt that an accused individual deserved it. This is particularly common in cases of bad character in which an accused has had a history of offences but has escaped punishment. Although corrupt as it is, testilying is merely seen as another way of getting the job done.   In conclusion, there is a huge interest towards police culture due to the impact it can and sometimes does have on society. if it is to have an influence on the way the police go about their work. The police hold a massively important role to society as they are a visible symbol of law and order and are granted various powers such as those which enable them to arrest members of the public who they feel prove a threat to the rest of society. Although most officers do operate in a reasonable manner, it is generally the actions of the minority which enable the public to misconceive that all officers are bigoted and aggressive. Such generalisations lead to a mass distrust of the police and tensions then begin to occur between the police and their publics. You only need to look at the summer riots of 2011 (which were reported to have been sparked by an officers seemingly unauthorised use of deadly force on a suspect) to see just how damaging poor police-community relations can be to the p olices image as a social institution.

The Opening of A Dolls House :: A Dolls House Essays

A critical analysis of the opening of the play A Dolls House. In the opening of the play "A Dolls House" ,the setting of the stage is of a house portrayed as if it were a dolls house. The items described in the house are all small therefore representing a dolls house where all items are miniature, the type of furniture owned , such as a piano, show that the family is moderately well off. There is no narrator in the play and all information and knowledge about the character is gained from listening to conversations. Ibsen has incorporated relevant information into conversations, this seems like a natural situation and makes the audience feel like they are looking onto a real house with real people. This means that the actors will have to act well so as to show audience with out seeming as if they are telling them. This means Ibsen had to write the opening of the play not only telling the audience what is going on but what has gone on. Nora is the first character introduced, and is shown entering the house on her own, the first sentence spoken in the play is said by Nora, this is to do with concealment and money. "The children mustn't see. How much is that?" This is significant to the rest of the play as these are two main themes used through the play. When Helmer (Nora Helmer's husband) enters he is then shown through out of the rest of the opening and the play, to treat Nora like a child using methods such as control and speaking to Nora in a patronising and child like manner. In the conversation between Nora and Helmer, Helmer refers to his wife as if she were inferior in the relationship using terms such as "songbird" and "squirrelkin". Nora in return replies to Helmer also using child like talk, such as referring to money as "pennies and pennies". Nora is also shown to be generous with money as she is tells the porter to "keep the change" this is an immediate indication that Nora is not worried about spending. Helmer also states that when Nora gets money it "melts in (her) hands" suggesting that she does not save .Nora's attitude towards money is also shown later in the opening when she shows no concern of borrowing money and being in debt. Nora also shows lack of feeling towards other people and there situation as long as she is ok , this shows a selfish nature as she says "why would U care if I still owed people money".

General and Application Controls in Information Technology

Information Technology has answered our many problems. It has made the life of individuals, groups and organization very easy compared to the former years where technology was something in dreams or on paper. Information Technology is referred to the various sophisticated and state of the art technology like computers that help us to manage our businesses (Senn, 2003).The most important part of the business for example is their huge amounts of data, the problem of storing them and then retrieving them for a useful purpose. Companies realize that data should never be treated as a useless collection of numbers, no matter how old they are. They also came to an appreciation that data can be used to give the companies the competitive edge they need, especially after they became conscious about the â€Å"marketing paradigm†.The Information Technology helps these companies to create, process, store, protect, transmit and retrieve data (Senft & Gallegos, 2008). Besides these, Informat ion technology has helped give impetus to the globalization process. It has reduced the world to a global village where the communication problem is no more an issue, especially after the advent of the internet. Now you can even make calls using the internet. All you need is a microphone and speakers to talk to anyone, at any time sitting anywhere in the world.The companies also realize that there processes (that take place within their organization to come up with their products) have become more cost effective (Senn, 2003). This has allowed business to efficiently utilize their resources and probably the most important one (which is usually saved at the end of the process) is the time. Through technology, companies are able to enhance the quality of their products and processes.BACKGROUNDGeneral Control of the Information Technology aids to guarantee the consistency of the data. This means that the data being produced is showing the performance of the system that you have installe d, and that it is producing the desired results. It ensures that the machine is working perfectly fine. You can then check upon your business process if there is an anomaly or inconsistency in your data. You can be sure of the right data for the wrong processes.Thus you can improve upon your business processes to correct your data. General Control of Information Technology usually encompasses the environmental control (Senft & Gallegos, 2008). This means that you understand the extent of the outside environment or the system beyond the boundary of your system and clearly out of your hands does shape your business in a certain way. But in what way does it affect you depends on the various environmental control you have at hand.USES AND IMPLICATIONSThe General Control also focuses on the different management changes that are brought within the business system or environment. Changes are a verily a very stressful task with in the organization.Information Technology helps to make sure t hat the changes brought therein is acceptable with the norms, organizational culture and the rules and regulations of the business itself (Senft & Gallegos, 2008). During the life of the business, many programs (complex or simples) are written to help businesses achieve their desired results.For example a company may find itself in the need of a Data Base Management Systems or a Data Warehouse. They may either purchase it or they may build it themselves. In both the cases, the company needs to mould the coding to suit their business requirements. It helps the source code’s reliability within the program.Businesses work on projects. For advanced business and for businesses that care to expand in the long run, find themselves in the need of developing software or systems. On the other hand, software houses whose main business is to develop and sell customer’s customized softwares goes through a complex life cycle to design, develop, test, implement and maintain the softw are.General Control helps to achieve that too. It helps to simplify the whole cycle which may extend to a number of years depending on the size and complexity of the software (Turban, Leidner, McLean, & Wetherbe, 2007).

Peanut Allergies

Peanut Allergies What is a peanut allergy? A peanut allergy is a reaction that involves our body’s  immune system. When we have a peanut allergy our immune system thinks that the peanut proteins are harmful and fight against it to protect our body. Peanuts are one of the nine most common  food allergens  in Canada. The other eight are: wheat, tree nuts (such as almonds, Brazil nuts, cashews, hazelnuts, macadamia nuts, pecans, pine nuts, pistachio nuts, and walnuts), sesame seeds, milk, eggs, seafood, soy, and sulphites (a food additive).Causes of peanut allergies: * Hereditary * Breast-feeding; But new evidence shows that when a mother eats peanuts, the peanut proteins flow into breast-milk and cause infants to develop the allergy antibodies, as well. * Direct contact. The most common cause of peanut allergy is eating peanuts or peanut-containing foods. * Cross-contact. This is the unintended introduction of peanuts into a product. It's generally the result of a food bei ng exposed to peanuts during processing or handling. * Inhalation.An allergic reaction may occur if you inhale dust or aerosols containing peanuts, such as that of peanut flour or peanut oil cooking spray. The most popular cause of peanut allergy is called the â€Å"hygiene hypothesis,† which says that people are just too clean these days. The result of the super-germ-free lives we lead and our readiness to treat infection with antibiotics is that our bodies don't know how to handle certain innocent proteins such as peanuts. Foods that causes the illness: * Peanuts and peanut products. * Tree nuts and their products. * Food that are exposed to peanuts.What are the signs and symptoms of an allergic reaction? An allergic reaction to peanuts can happen within minutes or up to several hours after eating foods containing peanuts. Symptoms vary from person to person, and may progress from mild to severe. Mild allergic reaction: * flushed face and body * itchy eyes, nose, face and s kin * tingling, numbness or pain in the lips and tongue Moderate to severe signs and symptoms * swelling of the eyes, face, lips, throat and tongue * hives * cramps, diarrhoea, vomiting * wheezing, coughing * weakness, dizziness * anxiety, distress, sense of fear and doomThere are some symptoms of the most serious form of peanut allergies called  anaphylaxis; which are very deadly and life-threatening. When a person is experiencing anaphylaxis reaction, he/she may have difficulty in talking swallowing and even breathing! Scientists have identified 19 peanut proteins–that can trigger anaphylaxis. It works this way: those with the allergy develop specific antibodies, known as IgE antibodies, which react to the peanut proteins. This triggers the release of histamine and other chemicals which cause facial swelling, and constrict the lungs airways and throat making it difficult to breathe.Without a shot of adrenaline, the reaction can cause death. Why is this an important issue that everyone should know about? This is an important issue that everyone should know about because comparing to 1980s the rate of people with peanut allergies has been reported to have increased by 95%. Although there are no hard statistics in Canada, most agree the allergy is on the rise. According to The Food Allergy & Anaphylaxis Network, Peanut allergy causes an estimated 15,000 emergency room visits each year and nearly 100 deaths. Safety precautions: . The safest way to avoid a peanut related reaction is to avoid all food and products that contain or may contain peanuts. 2. Other than that, create a plan for how to handle a reaction, just in case one occurs, and tell your friends, family, coaches, and teachers at school about your allergy 3. Always keep a shot of epinephrine, a hormone that controls anaphylaxis reactions. 4. Tell the server in a restaurant about your allergy so that he or she can steer you away from dishes that contain nuts. 5. Always read the ingredients lis t to be safe.
