Vagueness, Ambiguity, and Clarity in Writing Essay Example for Free

Vagueness, Ambiguity, and Clarity in Writing Essay Example 2: I was thrown from my truck as it left the road. I was later found in a ditch by a flock of wild turkeys. The vagueness about this sentence is it is not clear as to who was thrown from the truck you do not know what the writer meant. The second portion of the sentence is unclear on whether the wild turkeys are in the ditch the person is lying in or were they alongside the ditch the person was lying in. Example 3: Next Sunday a collection will be taken to help with the cost of the new altar. Anyone wanting to help to do something on the new altar can step forward and let the committee know. It is unclear actually what is being collected is it a collection of money or names in a basket to be called upon. Asking if anyone wants to do something to help on the new altar. The writer does not make it clear just what is being asked of what the â€Å"something† is on the new altar. These sentences are vague and ambiguous because it leaves too many ways that you could interpret the writers’ intent. Both vagueness and ambiguity is influenced in the understanding of these sentences because anyone could misunderstand what the writer is saying. As a writer, you must make very sure you get your ideas across clearly. The relationship between critical thinking and clear writing is that you first need to know actually what you want to say before you write it. Also you need to make sure that the research and information is accurate.

Software piracy: An overview

Software piracy: An overview SOFTWARE PIRACY IN AFRICA Software piracy is a combination of two different words which are software and piracy. Software can be defined as generic term for computer programs which operate the computer itself; Also Microsoft Encarta dictionary defined the word software as programs and applications that can be run on a computer system. Piracy can simply be defined as the unauthorized reproduction, doubling and distributing or use of copyrighted materials; as for this software piracy can be the illegal copying of software for distribution within the organizations, schools, homes or to friends, clubs and other groups, or for duplication, selling, and installing multiple copies onto personal and work computers. Citizens duplicate or copy software illegally from Macromedia, Adobe, Symantec, Autodesk, Microsoft, Grisoft e.t.c. Africa happens to be the worlds largest and second among the most heavily populated continent after Asia; it has different ethnic group. According to the piracy rate, Africa is one of the highest continents that has or make pirated soft wares in the world. With a 36% piracy rate, South Africa has the lowly piracy rate in Africa, where Nigeria and Kenya are the highest within the region as for 2000-2001 with 71% and 77% respectively as Zimbabwe has the highest in the world where South Africa has just one proportion above the overall average of 35%, according to the 3rd yearly International Data Corporation (IDC) and Business Software Alliance (BSA) overall software piracy study unconfined recently. South Africas piracy rate has decreased one proportion point in the current year, however still represents a 1.2b rand thrashing. The minor decrease in software piracy is qual ified to government act and the obtaining of renowned laptops other than desktop computers full by local assemblers. According to Stephan le Roux, the chairman of the Business Software Alliance (BSA) in South Africa in the following site: http://www.ibls.com/internet_law_news_portal_view.aspx?id=1516s=latestnews Editor, Maricelle Ruiz, IBLS Director Africa Wednesday, June 14, 2006 Software piracy ruins one of the main hurdles to understand the possible of the information economy in South Africa, on the continent and certainly roughly the world, As we are happy that piracy levels are dropping, there is still an anxiety for our local economy that over a third of software in use is against the law. This anxiety rises when you look at some countries in Africa, where as few as one in ten copies of packaged software are legally paid for. Due to the analysis made, the average rate for the African countries reviewed surpassed 70%, in Zimbabwe 90% of the software used is illegal and banned. Jointly with Vietnam, Zimbabwe has the maximum software piracy rate in the world. The mainstream of the African countries for which exact data is available Cameroon (84%); Botswana and Ivory Coast, Algeria and Zambia (83%), Nigeria and Senegal (82%), Tunisia and Kenya (81%) have a piracy rate above 80%. The study estimates that the rest of the countries in Africa, incorporated under the entry of extra Africa, have an average piracy rate of 84%. Egypt has been running to turn out to be a center for Arabic software, but also it has a 64% piracy rate with proportion point lower than the preceding year; while Morocco, which has just been highly praised by the humanity Intellectual Property Organization for adopting dealings to improve its IP system, contained a 68% piracy rate four proportion points lower than the preceding time. Morocc o is among the four countries with the leading proportion point in the preceding year. According to Angola press, quoting Hlatshwayo in http://www.warsystems.hu/?p=189 by bodo on 16/10/06 Zimbabwe, Nigeria, Botswana and Kenya are named as the principal culprits; and As a result of piracy in Africa Microsoft lost $31 million between 2004 and 2006. Many African developing countries need to have IT staffs and implements ICT to joint the todays global world, but to purchase single software is too expensive where they use this reason and makes piracy or uses pirated software; what ever be the case, reasons for copying or making piracy are categorized into 3: 1) purpose of use, 2) economic reasons, and 3) legal reasons. Purpose of use Reasons in this compilation transmit to the reason of use (non-commercial use, running purposes at home, studying, testing) or to the method of using the software (momentary use, compatibility reasons). The subsequent examples demonstrate these views: It is satisfactory in non-business use (for example, studying); it is not satisfactory for trade purposes. You preserve not research by means of costly software earlier than you purchase it experimenting previously makes executive simple and gives self-assurance, I experience the licensing cost for many equipment foolishly patronize while I work at home in addition to at work. Economic reasons In this compilation, the purpose for the illegal duplication of software is based on economic issues. According to respondents, the motives after these reasons are paucity (lack of money) and the wish to accumulate or save money (cost-benefit/efficiency). The subsequent extracts demonstrate these views: In a family there is a jobless computer professional who needs to preserve and keep up his professional Skills, but the family has no money, so the only opportunity is unlawful or illegal copying of computer software. The cost-benefit association does not arrive up to hope. think, for example, games, which one can only play from first to last once, and which outlay 250-350 Finnish marks 50-70 USD/EURO. Legal reasons In this compilation, the purpose for illegal duplication of software is based on legal issues. According to respondents, the rule was measured conventional, or it does not believe duplication as illegal doings. Examples follow: It is not unlawful for personal persons (in Finnish rule this subject is not an illegal offence as far as persons are concerned) the accessible rule is bad, hard and conventional concerning this issue. Software piracy is an act that is against the law and has many problems or harms; among the problems of software piracy are: Software companies compact with very high losses due to software piracy. Pirates expand a lot of money from their software piracy. People are not attentive that what they are doing is a crime. Reasons why the unauthorized copying of software is unacceptable are clustered into three different content categories: negative consequences, free software available, moral and legal reasons and other reasons. Negative consequences The reasons under this compilation are based on the perceived negative consequences of the unauthorized doubling of software. According to respondents, the duplication of software brings on the following kinds of harmful penalty: the worth of software grow weaker, Systems run out since people in all-purpose are not paying software, the cost of software rises and the motion affects sincere and truthful users. Some respondents wrote in ACM Digital library p-siponen: It is possible that the software will weaken in quality, if the software does not bring in anything (widespread copying). The producers of programs lose money and their future production [of software] will suffer. The price of software stays high because only a few buy software. Moral and legal reasons The respondents alleged wickedness at the same time as reasons against illegal copying of Software. Examples are as follows: dishonesty; if unlawful software is used on behalf of earning then that work is morally wrong. If software is duplicated destined for earning money or if it is copied in huge amounts or if individual earns ones income through repetition or copying, I believe those actions wrong I have lawfully bought some of the software I use, but I also have copies of software. If I ever need program/programs for purposes of earning my living, I will definitely buy it/them. The question here is Why Do Piracy Rates Differ? Generally unspecified factors to clarify piracy were grouped into four categories: economic factor, technical factor, regulatory factor and social factor. By looking at each of them individually: Economic Factors. Researchers have long documented the consequence of software price in piracy. According to Shin et al after his research in ACM Digital Library p-bagchi suggest that Gross Domestic Product (GDP) per capita is inversely related to software piracy level. Given the decrease in software prices, it may be that a countrys GDP has less of an effect on piracy than it did some years ago. GDP was bringing into being to be a major marker of piracy in 1996 however not in 2001 or in 2003. More, GDP only might give explanation barely 62%à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬63% of the difference in piracy. These findings may help clarify why dissimilar studies have indoors at dissimilar conclusions regarding the Role of GDP. It appears that the shrink in comparative cost of software has pointed the need for piracy. Specified the raise in piracy above this time, nevertheless, it follows that supplementary factors are concerned, and promote that these factors are rising in shock. Technical Factors. Software piracy is assumed to be more widespread in nations with low IT infrastructure given that the eminence of existing software is minor. Thus, people frequently copy and work with pirated software. The difficulty is compounded as software revisions occur. While the necessitate to remain ready for action in the course of upgrades is essential, it is meaningful only if reasonable lots of researchers also consider that software piracy has also flourished through the beginning of the Internet given that some Web sites offer a complimentary software or at prices cheaper than the manufacturers. Regulatory Factors. By commanding elevated tariffs, therefore ever-increasing the cost of software, governments may innocently support piracy. Developing nations repeatedly enforce elevated tariffs on computer products and thus their piracy rates are superior. It is also thought that low censures for import and elevated accessibility of pirated software are also reasons for piracy growth. Copyright rules are well thought-out foreign-induced, without problems understood and outlying fewer strictly forced. According to Meso et al in ACM Digital Library p-bagchi he identified enforcement of copy write laws as a salient issue in the development of a sound national IT policy. However, governments do not consistently implement such rules, partly because of lax law-enforcement facilities and institutional traditions that tend to ignore corruption. Thus, while enforcement of intellectual property rights and proper education may alleviate the problem, in reality few offenders are caught or pr osecuted. Occasional raid s from law-enforcement authorities have seldom disturbed the flow of pirated software. In nations that allow pirated software to be sold at lower prices, black markets have flourished. Individuals and companies in these nations may not even be aware that buying pirated software is illegal since the software has an aura of legitimacy. The overall effect of low censure and easy availability can be captured by the indicator of corruption. Corruption can be defined as the charge of obtaining rights that merely the State can lawfully award, such as preference in loans, taxation, subsidies, tariffs, regulation, and government contracting. Social/Cultural Factors. These factors pass on to the established social or construction of a country and the attitudes joint by members of that society. Single assess of social or public structure is the merit between independence, an insecurely joined social network where people take care of themselves and collectivism, a strongly joined social network where the group reaction is strong. Software piracy is popular in collectivistic societies where people tend to create a psychological detachment among members of the in-group and the out-group. Obligations or devotion to in-groups are measured awfully essential, and in switch over people look forward to that members of in-groups will look after them. Out-groups, on the other hand are not deemed valuable of esteem, given that they do not donate to the broad comfort of the in-group. In such societies, software purchased by a person is estimated to be collective among members of the in-group. given that nearly all collectivistic societ ies lean to be third-world or developing countries, software producers in overseas nations are viewed as out-group Even though software piracy is against the law there are certain companies that benefit from software piracy; according to the president of Microsoft Corps business division within a question at Morgan Stanley Technology Conference the president Jeff Raikes, he admitted to facilitate the companys benefits on or after software piracy in an obvious tilt of the hat to the open basis software giving out replica; he also added by saying there was a well line among seeing high numbers of consumers and making sure that they are using genuine products. He said our favorite objective is that we would like people to use our product. If theyre going to plagiarize someone, we would like it to be us to a certain extent than someone else, he further says. And thats because we appreciate that in the long run the basic benefit is the install foundation of people who are working with our products. Also in addition to that, according to Adrian a technology journalist and author who has devoted over a decade to helping users gets the most from technology. He also runs a popular blog called The PC Doctor. http://blogs.zdnet.com/hardware/?p=111 on 4 October 2006 said I have a propensity to control my property here to hardware related matters, but I experience forced to remark on the newest twistsin theWindows Genuine Advantage saga. This newest twist is the declaration that Windows Vista is to containtechnology comparable to WGA intoit.This statement came out on 4 October 2006viaMicrosoft Press Pass in the form of a press release announcing software protection platform (SPP). Now, whileI dont overlook software piracy for a minute, I use to get it tough tomake much compassionfor the Redmond monster. The method that Microsoft has implemented SPP and WGA doesnt formulate it obvious that the judgment agreed on a PC can be flawed. As an alternative they areforcing individuals who by mistake accused of software piracy to excavate bottomless hooked on their pockets and come up with an additional $149, all because of a software virus. That isnt just incorrect, its wickedness. Allow me suggest the subsequent reaction to career: mistakenly condemning somebody of software piracy is in addition not victimless. See, the thing that bothers me concerning Windows Genuine Advantage and Software Protection Platform is not so much the technology but rather the Draconian way Microsoft is wielding this power over users. Microsoft is confidently dedicated to the perspective that everyone flagged as running a duplicated copy of Windows have to be running a duplicated copy. If the system works and just picks up on individuals running non-genuine copies of Windows, thats great. The world believes that everything that has advantages must have disadvantages; after the advantage of software piracy according to some communities and companies; software piracy disadvantages many people through different ways like the pirate, manufacturers, permanent consumer. If the pirate is caught, he or she spend time in prison, faces rigid and the company also decides to force down charges; a pirate is very liable to download a Trojan or even spy ware, but due to the fact that he likely does a lot of downloading in general, and also because many invented cracks and keygens are actually malware in costume. If pirates are pirating software from a particular company, the company does not receive as much money for their product. To manufacture software can be very expensive, and the cost needs to be recouped in the shear bulk of sales. Due to lack of revolving large profit, they cannot have enough money to finance another round of development, research and also cannot produce new and enhanced versions. The consumers has to deal with the improved anti-piracy safeguards, such as entering product activation key code, and sometimes even a special dongle one must plug into their computer; categorize the company who makes the software to offset the effects mentioned above, they have to increase the per-copy price of the software. Even Microsoft is not immune to this, thats why they created a $300 version of windows vista, even though XP professional only cost perhaps $200. Software piracy has different issues like ethical, professional, social, and legal. Looking at the ethical and professional issues we have: Programmers and the theater artists lose income when copying and repetition is frequent; due to extreme software piracy software companies loses a lot. Certainly we have the freedom to make a copy for a friend, but are duplicating of software an act of sympathy on our part or an act that need kindness reaction from the programmer? Even though large-scale marketable piracy is inferior, individual duplicating is still not ethical. Pricing that is far lower than the manufacturers price can be a warning, but lots of people believe they are getting a good buy not a pirated program. Social issues are: There are lots of things we cannot find the money for; so not being able to afford software is not an excuse for duplicating it. The amount and success of a company do not give reason for enchanting from it. The quantity of people copying software does not verify if it is right or not. People buy pirated software without realizing what theyre doing i.e. without knowing the implications of doing it. Customers use to buy products, such as books and CDs that can be shared with friends and family. There are lots of ways customers can be fooled; in the sense that a pirated software dealer can sale many soft wares with a single key to the customers and within some days the software will request for original key. Legal issues are: But if you buy Windows, it doesnt belong to you, its Microsofts; theyre just leasing you use it. Software piracy gets 7 years in prison Is against the copyright law There are certain options to reduce software piracy; the solutions are categorized into four, namely ethical, social, legal, and market. We have protection under ethical, applying laws under legal, education under social and detection under market. Make sure the protection of leisure industry, publishers and software companies savings expected, or hoped-for revenues. Apply on hand laws, policy, guidelines or increase new ones to protect copyright owners, but also to look after fair use, sensible community access, and the chance to use new technologies to the fullest to supply new services. Technical, executive and lawful solutions include technologies to frighten duplication, selling and contractual changes that reduce the motivation to duplicate unlawfully. Educating with reference to the purpose for copyright guard, enforcement and reconsideration of copyright law. Ensure that citizens who work in manufacturing, marketing, and management are paid for the time and exertion they put to produce the vague academic property we benefit from. Also in addition to how to reduce or avoid software piracy in Africa on Monday, 30 July 2007 an article was released in http://www.mmegi.bw/index.php?sid=4dir=2007/July/Monday30 with the following heading: China in Raids to Limit Software Piracy in Africa The fight against computer software piracy in Africa has received a boost following raids and arrests made in southern China over the last two weeks, the result of the largest investigation of its kind in the world. The Public Security Bureau (PSB) in China, the Federal Bureau of Investigation (FBI) and hundreds of personal companies and allies have been functioning as one to crack a most important software forging association. The association was supposedly liable for distributing US$2 billion (about P12.3 billion) value of forged Microsoft software to 27 countries around the world, as well as Nigeria. Not only did this putting off software resellers from making lawful revenues, it also bare users to the risks related with using pi rated software. The forged goods detained in the raids comprised 13 of Microsofts most well-liked products, counting Windows Vista, Office 2007, Office 2003, Windows XP and Windows Server. Microsoft appreciates the work of Chinas Public Security Bureau in taking such burly enforcement action with these arrests and raids in southern China, said Abednego Hlatshwayo, Anti-Piracy Manager at Microsoft East and Southern Africa. This issue is supposed to serve as a come around call to forgers. Consumers and other organizations in the region of the world are revolving you in, and important act will be taken to defend intellectual property. In conclusions I learn that the software company is an area where home businesses can compete well with multinationals in both local and foreign markets. Yet, without suitable security in less-developed countries mainly African countries where piracy rates are reasonably higher, software pirates can devastate the income streams of small companies that have managed to effectively create particular niches in the companies. That piracy could be helpful to companies without the occurrence of Network effect. If customers have major dissimilarities in their minor value of Money, piracy can shrink competition and increase companys earnings. The solution to the Assessment is the fact that the same amount of money represents different worth to different customers. Poor customers usually value money more than rich customers. The companies therefore need to appoint in more excited competitions to attract these customers, which could be harmful on the whole profits of the company. And all softwa re companies should joint Hand and tackle the pirates via applying laws, educating and detecting them.

Previously to these reforms there had been a history of fragmentation between agencies and the therefore a inherent failure to share information resulting in catastrophic gaps in the support of vulnerable children. This was emphasised by Lord Laming (2002), and then the subsequent investigations and publication of the Climbie report (2003) post the preventable death of Victoria Climbie. The perceived importance of early identification and intervention as demonstrated in Every Child Matters. (2003, p3), DoH/DfES. (2004) We have to do more both to protect children and ensure each child fulfils their potential and the need for more co-located, multi-agency service in providing personalised support. The Childrens Act. (2004) was the culmination of the Green Paper DfES. (2003) Every Child Matters:Change for Children Agenda, which dictated that every local authority has power to administer grouped budgets and implement a Childrens Trust in order to pull together services to meet the specific needs of an individual child. Wilson, V. Pirrie, A. (2000) states that although partnership working is upheld as extremely beneficial for all children, those children with special educational needs and/or disabilities have formed the focus of much of the educational multi-agency activity. The aims of coordinating these services through a shared working practice across the health and education arena whilst providing a therefore seamless service of support and a one-stop shop for all provisions, supported with the collaboration of Multi-agency working, are strongly emphasised within a plethora of governmental literature DfES. (2003/2004). Joint working is therefore unequivocally viewed as the m eans of providing a more cohesive and therefore effective integrated approach to addressing the needs of the child and family, and in doing so, overcoming many additional stresses that are imposed on families through fragmented support and services and therefore giving the child the best possible start in life DoH. (2006). Although no one argues against the benefits of integrated services Stiff. (2007), and there is clear decisive backing and direction for local restructuring and reorganisation to shape services to meet the needs of the most vulnerable children more effectively, the detail surrounding the configuration and delivery of local services has not been prescribed Rutter, M. (2006). There is minimal research-based evidence regarding the efficiency of multi-agency practice or suggesting which activity carried out by those agencies is most useful, with no absolute model of the many factors influencing its success Salmon, G. (2004). However, the Government has demonstrated a s ubstantial commitment to local authorities developing multi-agency partnerships, providing considerable flexibility for those local authorities and communities to develop their own multi-agency activities, tailored to meet specific needs of their individual areas. However it has often proved difficult to establish the exact impact of multi-agency working, mainly because of the difficulty of isolating why and how a particular outcome has been achieved. This is changing as major programmes are evaluated, Atkinson et al, (2002) states that other commonly identified outcomes of multi-agency work are an increase in access to services not previously available and therefore a wider range of services, easier or quicker access to services or expertise, improved educational attainment and better engagement in education by pupils, early identification and intervention, better support for parents, childrens needs addressed more appropriately, better quality services, a reduced need for more spe cialist services and benefits for staff within those services. Introduction to the SEN Team (SENCo) There are many teams working within the umbrella of education and child services, one particular team is that of the Special Educational Needs team, this case study will focus on the role of the Special Educational Needs Coordinator (SENCo). The role of the SENCo has been formally established Cowne, E (2003) since the 1994 code of practice DFE (1994) when all schools in England and Wales were required to have a designated teacher in the role of special educational needs coordinator (SENCo). But many schools had SENCos before that date, as the role had been developing since the mid 1980s when training of SENCos had begun in most LEAs. The 1994 code of practice DFE (1994) detailed the tasks that should be covered in the role of the SENCo. These tasks included liaising with external agencies including the educational psychology service and other support agencies, medical and social services and voluntary bodies DFE (1994, para 2.14). A revised code of practice Dfes (2001) added the resp onsibility of managing the SEN team of teachers and learning support assistants within the educational establishment where recently publications.parliament.uk (2006) its significance was re-affirmed. SENCos play a key role in building schools capacity and skills in meeting childrens SEN because of their crucial role in advising other members of staff on SEN matters, linking with parents and working within the multi-agency arena. There is substantial literature related to SENCos authored by researchers, academics and practitioners, in particular, the nature, remit and working conditions of SENCos have been the subject of considerable interest. At school-level, the expectations on, activities of and working condition of SENCos remain highly variable. Barriers how are they overcome (Theory and practice) The achievement of effective multi-agency working within the SEN arena has proved more difficult to achieve than was initially anticipated. In order to create a climate of change where SEN professionals and agencies can work effectively together it is needed that the participants understand what the barriers to change are. Some of the barriers to achieving more effective multi-agency working within the SEN environment that have been identified by DFes (2007) are professionalism; conflicting priorities of different agencies; dealing with risk and the need to change the culture of organisations. Working in collaboration with other professionals and agencies involves SEN and multi-agency workers moving out of their comfort zone and taking risks. Anning, A. (2001, p.8) highlights, However, little attention has been given to two significant aspects of the operationalisation of integrated services. The first is the challenge for SEN workers of creating new professional identities in the ev er changing communities of practice (who I am). The second is for workers to openly communicate and share their personal and professional knowledge in order to create a new version of knowledge (what I know) for a new multi-agency way of working. Lownsbrough, H. and OLeary, D. (2005) states that Despite the genuine support of Every Child Matters, all SEN professionals are faced with the constant challenge of not reverting back to their comfort zone of their organisational boundaries, their professional authority and life inside these traditional boundaries can be far less complex and threatening, and after years of working in a particular fashion they are not easily forgotten. Although no one argues against the benefits of integrated services of multi-agency working Stiff, R. (2007), and there is clear strategic backing and direction for local restructuring and reorganisation to configure SEN services to meet the needs of the most vulnerable children more effectively. There is still little research-based evidence regarding the efficiency of multi-agency strategies or suggesting which activity is most useful, with no comprehensive model of the issues influencing its success Salmon, G. (2004). However, Government has demonstrated substantial commitment to local authorities developing multi-agency partnerships of which SEN is part of, and also providing considerable flexibility for local authorities and communities to develop their own multi-agency activities, tailored to meet their own local needs.Joined-up working has deep implications for the professionals working within the SEN teams, and for the agencies that commission their services. In multi-agency team work, professional knowledge boundaries could have a tendency to become blurred, professional identity can become challenged as roles, and responsibilities change. Some SEN team members may struggle to cope with the fragmentation of one version of their professional identity before a new version can be bui lt. Moreover, the rapid pace of SEN reform leaves little time for adjustment as SEN teams move (often within tight time scales) from strategic planning to operational implementation, with little time for joint training Birchall, E. Hallett, C. (1995). However, it could also be said Freeman, M, Miller Ross, (2002); Harker, Dobel-Ober, Berridge Sinclair, (2004) that SEN team members are more likely to deliver on their objectives with sufficient planning and support from partnering agencies that established the teams in the first place which inturn leads on to empower inter-professional collaboration which include not only enhancing coordination structurally, but also establishing a culture of commitment at a strategic and operational plane to overcome professionally differentiated attitudes. 4. The Way Forward It has been said Bowlby, J. (1988) that children need a secure base from which to explore the world. SEN practitioners also need a secure base in the knowledge that has been acquired though training and practice. Perhaps there is a need for an individual to value what they know and be confident about their knowledge. At the same time to be aware that their professionalism relies on constant updating of working practice and skills via work training and further education, and being aware that there is always something new to be learnt or shared. SEN Professionals now and in the future need to be able to draw on the professional skills that they have, but not to be dominated by them. If they are secure in what they know it could be said that this should enable them to have the confidence to challenge their own thinking and to be open to the different perspectives of other multi-agency professionals. Therefore it can be said that If SEN professionals are to challenge themselves and other s through collaborative dialogue they would also need to be emotionally contained themselves Bion, W. (1962). This act requires good honest SENCo leadership and a culture where trusting relationships can be built. Harris, B. (2004) described trusting relationships as broadly taking place within three dimensions, based in conceptions of emotionality. Effectively these dimensions add up to conditions in which staff first experience a sense of their own value within an organization, in which they feel comfortable about their own abilities and needs; second that through supportive relationships within the organization they reflect upon practice, in dialogue with colleagues, and thirdly they work together to create change and improvement in the setting, or organization, confident of support. Clearly, in order to build effective and trusting relationships SEN team members would need to understand themselves and to have the confidence to share more with others. This process of cultural cha nge is essential if multi-agency working is going to be able to provide better services to children and their families alike.

A military technology

A military technology CDMA is a military technology first used during World War II by English allies to foil German attempts at jamming transmissions. The allies decided to transmit over several frequencies, instead of one, making it difficult for the Germans to pick up the complete signal. Because Qualcomm created communications chips for CDMA technology, it was privy to the classified information. Once the information became public, Qualcomm claimed patents on the technology and became the first to commercialize it. Code Division Multiple Access technology emerged as an alternative to the GSM cellular architecture and has shared in the past decades explosive growth in the wireless market. CDMA, like GSM, has seen incremental improvements in capacity throughout this period. Now both types of networks are making a transition to third-generation (3G) systems around the globe, offering yet more capacity and data services. INTRODUCTION With the advent of wireless communication there was the advent of the two technologies for the cellular communication. They were the CDMA and the GSM technology. Both the technologies have their own mechanisms of working and their own pros and cons for which they have their own different utilizations and implications.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The technology on which our group has proposed to research is the CDMA (Code Division Multiple Access) technology. Though the total users of the CDMA technology around the globe are approximately 14% yet it has many advantages over the GSM technology which has enormous number of users. Actually the GSM technology is easy to manage and to handle rather than CDMA but that doesnt mean that it has got no future. Truly speaking the CDMA technology is the technology of the future. Gradually its gaining popularity in the European market. What is CDMA? CDMA (Code-Division Multiple Access) refers to any of several protocols used in so-called second-generation (2G) and third-generation (3G) wireless communications. As the term implies, CDMA is a form of multiplexing, which allows numerous signals to occupy a single transmission channel, optimizing the use of available bandwidth. The technology is used in ultra-high-frequency (UHF) cellular telephone systems in the 800-MHz and 1.9-GHz bands. CDMA employs analog-to-digital conversion (ADC) in combination with spread spectrum technology. Audio input is first digitized into binary elements. The frequency of the transmitted signal is then made to vary according to a defined pattern (code), so it can be intercepted only by a receiver whose frequency response is programmed with the same code, so it follows exactly along with the transmitter frequency. There are trillions of possible frequency-sequencing codes, which enhance privacy and makes cloning difficult. The CDMA channel is nominally 1.23 MHz wide. CDMA networks use a scheme called soft handoff, which minimizes signal breakup as a handset passes from one cell to another. The combination of digital and spread-spectrum modes supports several times as many signals per unit bandwidth as analog modes. CDMA is compatible with other cellular technologies; this allows for nationwide roaming. The original CDMA standard, also known as CDMA One and still common in cellular telephones in the U.S., offers a transmission speed of only up to 14.4 Kbps in its single channel form and up to 115 Kbps in an eight-channel form. CDMA2000 and wideband CDMA deliver data many times faster. Code Division Multiple Access (CDMA) is a digital air interface standard, claiming eight to fifteen times the capacity of traditional analog cellular systems. It employs a commercial adaptation of a military spread-spectrum technology. Based on spread spectrum theory, it gives essentially the same services and qualities as wireline service. The primary difference is that access to the local exchange carrier (LEC) is provided via a wireless phone. Though CDMAs application in cellular telephony is relatively new, it is not a new technology. CDMA has been used in many military applications, such as: Anti-jamming (because of the spread signal, it is difficult to jam or interfere with a CDMA signal). Ranging (measuring the distance of the transmission to know when it will be received). Secure communications (the spread spectrum signal is very hard to detect). CDMA is a spread spectrum technology, which means that it spreads the information contained in a particular signal of interest over a much greater bandwidth than the original signal. With CDMA, unique digital codes, rather than separate RF frequencies or channels, are used to differentiate subscribers. The codes are shared by both the mobile station (cellular phone) and the base station, and are called pseudo-random code sequences. Since each user is separated by a unique code, all users can share the same frequency band (range of radio spectrum). This gives many unique advantages to the CDMA technique over other RF techniques in cellular communication. CDMA is a digital multiple access technique and this cellular aspect of the protocol is specified by the Telecommunications Industry Association (TIA) as IS-95. In CDMA, the BSSAP is divided into the DTAP and BSMAP (which corresponds to BSSMAP in GSM). Generating a CDMA signal There are five steps in generating a CDMA signal. analog to digital conversion vocoding encoding and interleaving channelizing the signals conversion of the digital signal to a Radio Frequency (RF) signal The use of codes is a key part of this process. How CDMA is altering the face of cellular and PCS communication? CDMA is altering the face of cellular and PCS communication by: Dramatically improving the telephone traffic capacity Dramatically improving the voice quality and eliminating the audible effects of multipath fading Reducing the incidence of dropped calls due to handoff failures Providing reliable transport mechanism for data communications, such as facsimile and internet traffic Reducing the number of sites needed to support any given amount of traffic Simplifying site selection Reducing deployment and operating costs because fewer cell sites are needed Reducing average transmitted power Reducing interference to other electronic devices Reducing potential health risks Commercially introduced in 1995, CDMA quickly became one of the worlds fastest-growing wireless technologies. In 1999, the International Telecommunications Union selected CDMA as the industry standard for new third-generation (3G) wireless systems. Many leading wireless carriers are now building or upgrading to 3G CDMA networks in order to provide more capacity for voice traffic, along with high-speed data capabilities. CDMA is a form of Direct Sequence Spread Spectrum communications. In general, Spread Spectrum communications is distinguished by three key elements: The signal occupies a bandwidth much greater than that which is necessary to send the information. This results in many benefits, such as immunity to interference and jamming and multi-user access, which well discuss later on. The bandwidth is spread by means of a code which is independent of the data. The independence of the code distinguishes this from standard modulation schemes in which the data modulation will always spread the spectrum somewhat. The receiver synchronizes to the code to recover the data. The use of an independent code and synchronous reception allows multiple users to access the same frequency band at the same time. In order to protect the signal, the code used is pseudo-random. It appears random, but is actually deterministic, so that the receiver can reconstruct the code for synchronous detection. This pseudo-random code is also called pseudo-noise (PN). There are three ways to spread the bandwidth of the signal: Frequency hopping. The signal is rapidly switched between different frequencies within the hopping bandwidth pseudo-randomly, and the receiver knows before hand where to find the signal at any given time. Time hopping. The signal is transmitted in short bursts pseudo-randomly, and the receiver knows beforehand when to expect the burst. Direct sequence. The digital data is directly coded at a much higher frequency. The code is generated pseudo-randomly, the receiver knows how to generate the same code, and correlates the received signal with that code to extract the data. HOW SPREAD SPECTRUM WORKS? Spread Spectrum uses wide band, noise-like signals. Because Spread Spectrum signals are noise-like, they are hard to detect. Spread Spectrum signals are also hard to Intercept or demodulate. Further, Spread Spectrum signals are harder to jam (interfere with) than narrowband signals. These Low Probability of Intercept (LPI) and anti-jam (AJ) features are why the military has used Spread Spectrum for so many years. Spread signals are intentionally made to be much wider band than the information they are carrying to make them more noise-like. Spread Spectrum signals use fast codes that run many times the information bandwidth or data rate. These special Spreading codes are called Pseudo Random or Pseudo Noise codes. They are called Pseudo because they are not real Gaussian noise. Spread Spectrum transmitters uses similar transmit power levels to narrow band transmitters. Because Spread Spectrum signals are so wide, they transmit at a much lower spectral power density, measured in Watts per Hertz, than narrowband transmitters. This lower transmitted power density characteristic gives spread signals a big plus. Spread and narrow band signals can occupy the same band, with little or no interference. This capability is the main reason for all the interest in Spread Spectrum today. IMPLEMENTATION OF CDMA TECHNOLOGY Now a day, in large organization the communication process has to be fast and efficient. There are the major points that have to be taken care in the modern corporate culture. Over time, more and more demands have been made on the capabilities of corporate networks. Workers want more mobility; secure, high-speed access; and an extension of applications across the enterprise, all of which can strain current IT capabilities. The first and foremost of all is protecting corporate network assets is an ongoing task for IT professionals. Increased worker mobility and mobile workers needs for immediate, secure access to critical business information add challenges to maintaining network security Some of todays top security issues and concerns are: Unauthorized systems and network access Auditability and compliance Customer data breaches Internal and external sabotage Theft of intellectual property and confidential business information Cost of mobile device administration The following diagram illustrates many elements critical to mobile data security. DIFFERENCE BETWEEN GSM AND CDMA TECHNOLOGY In cellular service there are two main competing network technologies: Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA). Cellular carriers including Sprint PCS, Cingular Wireless, Verizon and T-Mobile use one or the other. Understanding the difference between GSM and CDMA will allow you to choose a carrier that uses the preferable network technology for your needs. The GSM Association is an international organization founded in 1987, dedicated to providing, developing, and overseeing the worldwide wireless standard of GSM. CDMA, a proprietary standard designed by Qualcomm in the United States, has been the dominant network standard for North America and parts of Asia. However, GSM networks continue to make inroads in the United States, as CDMA networks make progress in other parts of the world. There are camps on both sides that firmly believe either GSM or CDMA architecture is superior to the other. That said, to the non-invested consumer who simply wants bottom line information to make a choice, the following considerations may be helpful. Coverage The most important factor is getting service in the areas you will be using your phone. Upon viewing competitors coverage maps you may discover that only GSM or CDMA carriers offer cellular service in your area. If so, there is no decision to be made, but most people will find that they do have a choice. Data Transfer Speed With the advent of cellular phones doing double and triple duty as streaming video devices, podcast receivers and email devices, speed is important to those who use the phone for more than making calls. CDMA has been traditionally faster than GSM, though both technologies continue to rapidly leapfrog along this path. Both boast 3G standards, or 3rd generation technologies. EVDO, also known as CDMA2000, is CDMAs answer to the need for speed with a downstream rate of about 2 megabits per second, though some reports suggest real world speeds are closer to 300-700 kilobits per second (kbps). This is comparable to basic DSL. As of fall 2005, EVDO is in the process of being deployed. It is not available everywhere and requires a phone that is CDMA2000 ready. GSMs answer is EDGE (Enhanced Data Rates for GSM Evolution), which boasts data rates of up to 384 kbps with real world speeds reported closer to 70-140 kbps. With added technologies still in the works that include UMTS (Universal Mobile Telephone Standard) and HSDPA (High Speed Downlink Packet Access), speeds reportedly increase to about 275à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬380 kbps. This technology is also known as W-CDMA, but is incompatible with CDMA networks. An EDGE-ready phone is required. In the case of EVDO, theoretical high traffic can degrade speed and performance, while the EDGE network is more susceptible to interference. Both require being within close range of a cell to get the best speeds, while performance decreases with distance. Subscriber Identity Module (SIM) cards In the United States only GSM phones use SIM cards. The removable SIM card allows phones to be instantly activated, interchanged, swapped out and upgraded, all without carrier intervention. The SIM itself is tied to the network, rather than the actual phone. Phones that are card-enabled can be used with any GSM carrier. The CDMA equivalent, a R-UIM card, is only available in parts of Asia but remains on the horizon for the U.S. market. CDMA carriers in the U.S. require proprietary handsets that are linked to one carrier only and are not card-enabled. To upgrade a CDMA phone, the carrier must deactivate the old phone then activate the new one. The old phone becomes useless. Roaming For the most part, both networks have fairly concentrated coverage in major cities and along major highways. GSM carriers, however, have roaming contracts with other GSM carriers, allowing wider coverage of more rural areas, generally speaking, often without roaming charges to the customer. CDMA networks may not cover rural areas as well as GSM carriers, and though they may contract with GSM cells for roaming in more rural areas, the charge to the customer will generally be significantly higher. International Roaming If you need to make calls to other countries, a GSM carrier can offer international roaming, as GSM networks dominate the world market. If you travel to other countries you can even use your GSM cell phone abroad, providing it is a quad-band phone (850/900/1800/1900 MHz). By purchasing a SIM card with minutes and a local number in the country you are visiting, you can make calls against the card to save yourself international roaming charges from your carrier back home. CDMA phones that are not card-enabled do not have this capability, however there are several countries that use CDMA networks. Check with your CDMA provider for your specific requirements. According CDG.org, CDMA networks support over 270 million subscribers worldwide, while GSM.org tallies up their score at over 1 billion. As CDMA phones become R-UIM enabled and roaming contracts between networks improve, integration of the standards might eventually make differences all but transparent to the consumer. The chief GSM carriers in the United States are Cingular Wireless, recently merged with ATT Wireless, and T-Mobile USA. Major CDMA carriers are Sprint PCS, Verizon and Virgin Mobile. There are also several smaller cellular companies on both networks.

Munchausen Syndrome Essay -- Disease/Disorders Health

Munchausen Syndrome History Munchausen Syndrome, an illness of psychiatric nature, was first introduced by Richard Asher in 1951 (Zibis et al., 2010). Although Munchausen Syndrome had been described in 1931 by Karl Menninger in medical publications it wasn’t until 1951 that Richard Asher published three case reports and the disorder gained interest (Turner, Reid 2002).The syndrome, as described by the Merck Manual for Healthcare Professionals (2008), is a severe form of a factitious disorder in which the patient tends to feign some kind of illness (physical or mental) without an external reason. Richard Asher was a renowned British endocrinologist and hematologist who is said to have named the syndrome after the fictionalized accounts of Baron Karl Friederich Munchausen (1720-1791) a German soldier who was famous for the adventurous tales about his life (Murray, 1997). Consequently because of the extensive traveling, peculiar stories and refractory treatment, as more cases appeared the syndrome took on various names such as the following: pathologic malingering, chronic factitious illness, and peregrinating problem patients (Justus, Kreutziger, Kitchens 1980). Diagnosis Patenaude, Zitsch, and Hirschi (2006) define a factitious disease as one in which the patient consciously and purposely injures themselves in order for a physician or caretaker to make a wrongful diagnosis and thus be submitted to treatment. Munchausen Syndrome is characterized by the patients’ continuous attempt for admittance at hospitals after a dramatic show of physical symptoms (Zibis et al., 2010). The disorder is associated with severe emotional problems specifically in patients with histrionic or borderline personalities; these ten... ... http://www.merckmanuals.com/professional/print/psychiatric_disorders/somatoform_and_factiti ous_disorders/munchausen_syndrome.htm Murray, J.

Black Americans Struggle in Baldwins Stranger in the Village :: Stranger Village Baldwin Essays

Black Americans' Struggle in Baldwin's Stranger in the Village In ?Stranger in the Village? (1955), James Baldwin, a writer born and raised in Harlem, experiences extreme emotions during his stay in a 'tiny Swiss village'(127). James Baldwin?s feelings of inadequacy and insecurities of being an American black man bring out a rage in him toward the white man's power over him. His deep feelings of outrage, bringing back hurtful memories as a black child in America, are revived as he is forced to endure the unintentional cruelties of the villagers. Baldwin asserts that even the most simple-minded white man has more control and history over Baldwin than Baldwin's desire to reclaim his culture. As his outrage mounts, Baldwin admits that the black man intends to make the white man stop acknowledging him as an 'exotic rarity and recognize him as a human being'(131). Baldwin further reveals he is tired of getting looked at with curiosity and deception; he desperately yearns to be accepted as an American man. Furthermore, Baldwin's anguish at the loss of the American Negro slave's history, as it was taken away from them, enrages and saddens him, yet he doesn't truly blame the white man because the white Americans were only following in the footsteps of the Europeans of the past. In this context, from Baldwin's perspective, Europeans experienced no dilemma of cons cience towards the black man, and he just 'did not exist for Europe'(132). Americans, on the other hand, faced a moral conflict to recognize the black man?s identity without poisoning their own (133). Despite his rage and aggressive support of the black man?s struggle in America, he strove for humane treatment in a racist society. Baldwin sought to bring about acceptance and a better future for black Americans and having feelings of inadequacy and insecurity determined him to bring change to America: ?This world is white no longer, and it will never be white again?(135). This statement is not meant to be taken at face value.

Importance Of Continuing Professional Development Essay

Continual professional development is improving ones skill and abilities benefiting the individual and the organisation. It is also taking responsibility for ones learning. In these changing times where most people no longer have a job for life, learning is crucial for employability, also as business technology evolves at a much faster pace, individuals need to keep up to date with latest way of doing things – CPD can help to achieve this. My development needs There are different means by which you can develop your skills, knowledge and behaviours, for instance by accessing the Cipd website, reading daily alerts, resourcing journals online and by attending Cipd events I am able to keep up to date with current issues across the sector. I have already started to do this, and have booked myself onto some of the Cipd events. I can improve my knowledge by planning time to go through financial and reporting systems that my organisation uses, with my line/ store manager. I can also research the company intranet, as it contains a wealth of information. By attending ‘Vision’ courses in my workplace I start to think about my personal behaviours, such as self-awareness, which in turn can help me be a better role model for others. I have an interest in performance and reward management and so I am looking forward to the module on this, I will also be having a thorough look at this in my workplace, and also plan to look into performance an d reward that our competitors offer. CPD is important to me for the following reasons,  1, to enable me to improve my skill set making me more employable across the sector. 2, to help build my self-confidence, in a competitive job market. 3, to enable me to be aware of current goings on within the sector. 4, It will make me a more knowledgeable individual which will in turn benefit my team and organisation. Development Options There are many different ways of meeting continued professional needs, and different tools that can be used to help learning, these include reinforcement theories, cybernetic and information theories, cognitive  theories and problem solving and the experiential learning cycle. There are different learning style questionnaires that help people to identify which style of learning suits them, this can then be used to deliver training and learning. For example, Honey and Mumfords learning cycle suggests the following learning styles, Activist, Reflector, Theorist and Pragmatist. The VARK questionnaire is a similar tool concentrating on Visual, Aural, Read and Kinaesthetic methods of learning. In most cases people fall into more than one category, so learning styles need to be adapted so that people are able to get something out of the training. It is important to keep the training varied to account for this. Personally I prefer a mix of visual images to support my learning with some text. I also prefer to see something in conjunction with listening to a lecture, I find the visual image helps to embed the learning. It is important to be open to new styles of learning, and if I find that I am struggling with something using the internet to help find a different reports which I may find easier to understand.

BB concepts

Transactional (timely exchange of products and services) Value-added (falls between transactional and collaborative) Collaborative (alternatives are less, complex purchases and high prices) Transactional: Timely exchange of g/s in a highly competitive market in terms of prices. Autonomous, no/little concerns towards the need of customers or sellers. The relationship ends once the purchase Is done Types of products- packaging, cleaning products or commodity products where bidding is involved Collaborative:Occurs when few alternatives are present and involves complex purchases. Prices too are high. Switching costs are very high and extremely important to collaborative customers. This is because the organizational customers invest in their relationships in the following areas: Money People Training costs Equipment Procedures & Processes The needs of both the customer as well as the seller is taken care of. Trust and commitment are the key factors In such a relationship and they exists w hen one party has complete confidence In the other partner's Integrity and ability.Egg: IBM/GE/ Intel/ DuPont- Sucrose, etc. In case of high tech IT products, collaborative relationship can be very beneficial. It focuses on joint problem solving and resource sharing. Value drivers in Collaborative exchange: Value creation through core offerings- direct cost, delivery performance Value creation within sourcing process- acquisition cost Value creation at the customer level of operations- ops In order to achieve the key supplier status In collaborative exchange, one must- Target the right customerMatch with their purchase requirements Develop strategies to build trust and commitment in order to reduce the perceived risk in the minds of the buyers. Value-added In-between transactional and collaborative. They are those businesses which apart from Just attracting customers also try and retain customers by: Providing additional services Developing customized services according to customer needs Provide incentives to the customers on a regular basis to retain them Egg: Tate & Lyle and food ingredients The buyer seller relationship depends mainly on:Market conditions- Highly volatile/ less alternatives go for collaborative, Low prices/ low complexity go for transactional o/w collaborative Improving transactional customer loyalty: Adopt differentiation strategy- this strategy suggests that the value created to the customers which is measure by high margins and sales should exceed the cost involved in creating and delivering the customized product/ services. Adopt activity based costing- BBC is a method that allocates the cost of performing various service to each customer.This will enable the firms to accurately identify who are the most profitable customers. The whale curve which is the result of BBC tells that 80% of sales revenue comes from 20% of the customers. The firms should therefore either retain the most profitable customers, convert unprofitable one to profit able or fire those who are not profitable. Managing unprofitable customers- Reduce cost to serve Increasing profitability- life time value All this can be done through adopting the right CRM strategy The CRM strategy: Acquire the right customers
