Racism on the Internet Kristofer Palmer Texas AM University San Antonio Aug 8, 2014 Racism and dissemination based on hatred and racial superiority were pressing social problem prior to the emergence of the information age and digital communications. Long before the internet entered our homes racist groups made use of other communication tools including the telephone networks as far back as the 1970s. However the advancement of the digital communication age has added a new dimension to this problem by providing individuals in organizations modern and powerful means to support racism in xenophobia. The Internet is becoming our main means of communication creating a unique set of challenges and communication barriers particularly when it comes to the proliferation of extremist and racist material. The internet functions as a dangerous facilitator for various racist messages, and the proliferation of racist material will continue with the increased usage of the internet. The Internet has made great leaps in the field of personal freedom however that has also led to an increase in racism and extremism which can lead to the destruction of human empathy. All racist websites are hate oriented sites, but while hate sites often carry racist information, some may also contain anti-abortion extremist and anti-gay information as well.

His scorn of the gods, his hatred of death, and his passion for life won him that unspeakable penalty in which the whole being is exerted toward accomplishing nothing.

string(168) " bend will depend upon their general IT or package accomplishments and besides for how long they have been utilizing the system and how frequently they use the system\." Introduction I have worked in the Work based Learning proviso and hence understands the demand and importance of learner direction systemsÃ¢â¬ ¦ without which the whole system will be in muss. There is a batch of conformity demand as the programmes we provide are chiefly funded through the SFA ( Skills Funding Agency ) or ESF ( European Social support ) and inspected by the Ofsted. It is non possible for a individual individual to retrieve or organize all these things hence there is a demand for a LMS which will remind you to make the assorted things, generate appropriate studies, co-ordinate between the scholar, employer, coach, presenting organic structure and the support organic structure. We will write a custom essay sample on The Need And Importance Of Learner Management Systems Education Essay or any similar topic only for you Order Now Work Based Learning has been defined nationally as Ã¢â¬ËLearning for, at or through work Ã¢â¬Ë Learning for work loosely encompasses Ã¢â¬Ëanything which can be labeled Ã¢â¬Ëvocational Ã¢â¬Ë as delivered in school, college, sandwich classs, in BTEC Nationals in hairdressing/beauty and manner, mechanical technology, humanistic disciplines and ocular, or even wellness, kid and societal attention. Learning at work every bit related to developing and development delivered in-company such as Business direction accomplishments, client service, wellness and safety ; and Learning through work that includes the application of job-related acquisition ( perchance acquired elsewhere ) and the accomplishments and cognition acquired in the procedure of making the occupation such as athleticss manager, attention work, mechanics. Work Based Learning is one of the most popular flagship of the current and old authoritiess. The degrees of hapless attainment of accomplishments in the instruction sector had become a serious affair of grave concern. More and more kids were go forthing school without any accomplishments, needed cognition or direct vocational experience. They were mostly unemployable due to hapless literacy, numeracy, scientific and ICT accomplishments and represent a immense societal liability, which was manifested by their engagement in anti societal offenses, or hapless negative behavior forms, taking to detonations of their admittances into unafraid disciplinary penal establishments. The deficiency of accomplishments of the Youth in United Kingdom is besides a major concern to industry and employers. Rather than prosecute in neÃ¢â¬â¢er stoping blasted addition, the new Government has launched enterprises that appear to go on with known policies of promoting work based larning chiefly Apprenticeship schemes to be equipped with the critical accomplishments needed to be gainfully employed . This survey relates merely to the funded work based learning proviso, all of which are in range for review by Ofsted ( Office for Standards in Education ) and audit by the support organic structures like SFA ( Skills Funding Agency ) , ESF ( European Social Funding ) etc. The procedures involved in the Work based proviso are much complex than the normal preparation colleges, besides as they are funded proviso they need to keep grounds that the money given by the support organic structures have been spent right as by the eligibility counsel and the undertaking counsel. Work Based Learning proviso involves three chief participants Ã¢â¬â the supplier, the employer and the scholar. As the complexnesss kept increasing the suppliers felt it really hard to pull off efficaciously the whole procedure this gave rise to the demand of a scholar direction system ( besides known as direction information system ) to administrate and pull off the whole procedure efficaciously and besides to cut down staffing cost and mistakes. Today there are tonss of package which are used by the WBL suppliers in UK, the chief being PICS by pellcomp package and Maytas by Tribal. Learner direction system does the occupation of the directorÃ¢â¬ ¦ it is non merely for pull offing the scholars but besides for helping the supplier for record maintaining, coverage and for communicating between the employer, supplier and the scholar. Learner Management system has ever been confused with the e-learning but really LMS is a portion of E-learning. By Ã¢â¬Ëe-learning Ã¢â¬Ë we mean: Ã¢â¬ËThe bringing and disposal of larning chances and support via computing machine, networked and web-based engineering to assist single public presentation and development Ã¢â¬Ë ( Pollard and Hillage, 2001 ) . There are assorted engineerings which contribute to e-learning for WBL suppliers viz. : Learner Management System Ã¢â¬â for pull offing scholar, employers, learning staff and for assorted conformity demands Learning Content direction system Ã¢â¬â It involves development, direction and publication of the content that will typically be delivered via a Learning Environment Learning Environment Ã¢â¬â Learning Environment is a environment where scholars and learning staff can interacts. VLE is a type of web-based acquisition environment which brings together in an incorporate environment, a scope of resources that enable scholars and staff to interact online, and includes content bringing and trailing. Learner Assessment System or E-portfolios Ã¢â¬â for on-line testing or measuring scholars A batch of research has been done on E-learning and VLE and besides Becta has been making research on the e-maturity of WBL suppliers, Becta research has greatly influenced this research and besides relevant information has been used from the Becta research as a secondary information which has formed the portion of determination of this research. RESEARCH AIM The purpose of the proposed research is to look into the user satisfaction of the Learner Management System used by the funded Work Based Learning Suppliers in Greater London. Research OBJECTIVES Its specific aims are to: Identify tendencies for WBL suppliers in their use of Learning Management systems look into the impact of Learning Management systems on the overall quality of proviso place for what different intent is the LMS being used by the suppliers look into the degree of staff accomplishments in the usage of LMS place whether clip spend by the user utilizing LMS has impact on the user satisfaction place how cost effectual the LMS system is and what impact it has on user satisfaction RESEARCH HYPOTHESIS The user satisfaction of the Learning Management systems amongst funded Work Based Learning suppliers depends on the undermentioned variables Ã¢â¬â Users skill Cost effectivity Functions the LMS supports User Skill will include how competent the users are in utilizing the Learning Management system which in bend will depend upon their general IT or package accomplishments and besides for how long they have been utilizing the system and how frequently they use the system. You read "The Need And Importance Of Learner Management Systems Education Essay" in category "Essay examples" Cost Effectiveness will include the existent cost of the LMS, clip saved by the users utilizing the LMS, the decrease in the labor cost and the mistake decrease Functions the LMS support will include how helpful the LMS is in back uping through the assorted procedures of WBL, how good incorporate it is with other sytems A user will be more satisfied with the LMS if he/she is more skilled A user will be more satisfied with the LMS if it is cost-efficient A user will be more satisfied with the LMS if it support more maps Research Background: A turning tendency of instruction and preparation in UK is Work based Learning where employees, particularly immature 1s, are provided assorted signifiers of chances to develop and better their numeracy, literacy, ICT, client service and other related proficient and vocational accomplishments, cognition and practical industrial cognize how. It is widely acknowledged that to assist concerns to win in this clip of economic challenge, it is critical that employers invest in accomplishments. Training additions productiveness in the short termA Ã¢â¬â and employers who do nÃ¢â¬â¢t develop are two times more likely to neglect than those who do. Research shows that three in four concern people ( 76 % ) believe that their organisation would non win without investing in preparation, hence Work Based Learning is a really of import signifier of acquisition. Apprenticeships and Train to Derive are two most of import funded work based larning programmes.. Apprenticeship is a system of developing a new coevals of practicians of a accomplishment. Apprentices ( or in early modern use Ã¢â¬Å" learners Ã¢â¬ ) or proteges construct their callings from apprenticeships. Most of their preparation is done while working for an employer who helps the learners learn their trade, in exchange for their go oning labor for an in agreement period after they become skilled. Theoretical instruction may besides be involved, informally via the workplace and/or by go toing vocational schools while still being paid by the employer Apprenticeships have a long tradition in the United Kingdom, dating back to around the twelfth century and flourishing by the fourteenth century. The parents or defenders of a child would hold with a Guild Ã¢â¬Ës Master craftsman the conditions for an apprenticeship which would adhere the child for 5-9 old ages ( e.g. from age 14 to 21 ) . They would pay a premium to the craftsman and the contract would be recorded in an indentation. In 1563, the Statute of Artificers and Apprentices was passed to modulate and protect the apprenticeship system, prohibiting anyone from practising a trade or trade without first functioning a 7-year period as an learner to a maestro. From 1601, Ã¢â¬Ëparish Ã¢â¬Ë apprenticeships under the Elizabethan Poor Law came to be used as a manner of supplying for hapless, illicit and orphaned kids of both sexes alongside the regular system of skilled apprenticeships, which tended to supply for male childs from somewhat more flush backgrounds. These parish apprenticeships, which could be created with the acquiescence of two Justices of the Peace, supplied learners for businesss of lower position such as farm labouring, brick devising and humble family service. In the early old ages of the Industrial Revolution entrepreneurs began to defy the limitations of the apprenticeship system, and a legal opinion established that the Statute of Apprentices did non use to trades that were non in being when it was passed in 1563, therefore excepting many new eighteenth century industries. In 1814 compulsory apprenticeship by indentation was abolished. The consequence of this was the low end product of skilled forces in technological industries, which in bend relegated UK into the lower ranks of advanced societies. Since so Apprenticeship has ever been really popular and besides has been the most favoured by the assorted authoritiess. As employees, learners earn a pay and work aboard experient staff to derive job-specific accomplishments. Off the occupation, normally on a day-release footing, learners receive preparation to work towards nationally recognised makings. Anyone life in England, over 16 and non in full-time instruction can use. Apprenticeships can take between one and four old ages to finish depending on the degree of Apprenticeship, the learners Ã¢â¬Ë ability and the industry sector. Train to Gain is the authorities Ã¢â¬Ës flagship supplying accomplishments based developing to employees. Train to Gain is portion of the Governments Solutions for Business, a broad portfolio of extremely targeted, publically funded concern support merchandises and services, designed to helpA eligible English concerns grow and win. As the national accomplishments service Train to Derive: purposes to run into the demands of employers of all sizes and from all sectors to better the accomplishments of their employees as a path to bettering their concern public presentation purposes to promote all concerns and persons to value and gain the benefits that larning and accomplishments can convey is a valuable resource for employers, unlocking employees Ã¢â¬Ë possible and increasing company productiveness A wide scope of preparation is covered Ã¢â¬â from basic degree accomplishments to Level 2, Level 3 and other higher-level accomplishments such as Leadership and Management. As of today Train to Derive is to stop by July 2011 and new support programme will replace it but it will merely fund degree 2 makings and most suppliers are expected to exchange to apprenticeships programmes. Coalition Government Policy: In acknowledgment of the turning importance of work based acquisition, the new Coalition Government in United Kingdom has lent its support to this industrial tendency: The Secretary of State for Education, Michael Gove, commissioned Professor Alison Wolf of King Ã¢â¬Ës College London to transport out an independent reappraisal of vocational instruction. She was asked to see how vocational instruction for 14- to 19-year-olds can be improvedA in order toA promote successful patterned advance into the labour market and into higher degree instruction and preparation paths. She was besides asked to supply practical recommendations to assist inform future policy way, taking into history current fiscal restraints. The reappraisal has been informed by over 400 pieces of grounds from the populace, a figure of visits to colleges, academies and developing suppliers, and interviews and treatment Sessionss with cardinal spouses in the sector, and cardinal recommendations in the reportA include the followers: incentivising immature people to take the most valuable vocational makings pre-16, whileA taking inducements to take big Numberss of vocational makings to the hurt of nucleus faculty member survey presenting rules to steer survey programmes for immature people on vocational paths post-16 to guarantee they are deriving accomplishments which will take to progression into a assortment of occupations or further acquisition, in peculiar, to guarantee that those who have non secured a good base on balls in English and mathematics in GCSE continue to analyze those topics measuring the bringing construction and content of apprenticeships to guarantee they present the right accomplishments for the workplace doing certain the regulative frameworkA moves quicklyA off from recognizing single makings to modulating presenting administrations taking the demand that all makings offered to 14- to 19-year-olds tantrum within the Qualifications and Credit Framework, which has had a damaging consequence on their rightness and has left spreads in the market enabling FE lectors and professionals to learn in schools, guaranting immature people are being taught by those best suitable Before the Learner Management Systems or package the coverage and tracking all of scholars, classs and coachs was done through the usage of a individual maestro spreadsheet. To enable studies to be compiled, transcripts of this maestro spreadsheet would be taken and edited, which proved to be cumbersome, non really effectual and really clip consuming. Besides these chief spreadsheets were merely available at the chief office which meant that any coach or scholars who would necessitate some information needs to come to the office or when transcripts of this spreadsheet were taken off site, which on occasion happened, nevertheless this so lead to issues with versions of the maestro as updates may hold been done to this dispersed sheet off site whist other members of staff may hold made alterations to the on site transcript. Leading to issues with truth of the overall maestro spreadsheet, this was one of the trouble faced by most suppliers before the Learner Management Systems like PICS and Maytas came in the image. PICS is the most popular Learner Management system used by the Work Based Learning Suppliers in England. The chief characteristics of PICS are Ã¢â¬â Research Methodology: The system of roll uping informations for research undertakings is known as research methodological analysis The research will be undertaken in two phases: a literature reappraisal on the usage of e-learning in work-based learning proviso, covering authorities strategic and research publications, research by the LSC, Becta, JSIC and other bureaus, academic diaries, industry-related web sites and publications, specific undertaking studies and ratings. desk research including interviews and questionnaires with directors and practicians Ã¢â¬â which involves admin staff, coachs, assessors and Internal Verifier. Exploratory surveies will be conducted to derive acquaintance with the topical countries and generate thoughts through the reappraisal of available literature from beginnings such as Becta research, LSC ( now Skill Funding Agency ) , JISC and others. Pilot interview Ã¢â¬â restructure the inquiries as necessary Pilot usage of questionnaire Ã¢â¬â restructure the inquiries as necessary Contact inside informations of assorted s Letters/Emails bespeaking purpose, purposes and aims of the survey would be sent out to different administrations presenting Work Based Learning proviso in Greater London. Online questionnaire or paper based questionnaires will be sent out to the directors of these administrations. Online Questionnaires or paper based questionnaires will be sent out to the bringing staff of the administrations presenting Train to Derive proviso. Interviews will be conducted with cardinal staff of the administrations bringing work based learning proviso Analysis of secondary informations such as becta research and published one-year studies and academic diaries. Consideration of the informations and forms found in all of the administrations will be used in concurrence with academic theory to seek to explicate the findings and reply the research aims posed in subdivision Mistake: Reference beginning non found. Validity and Reliability In the design of the research attack I have considered the followers: Internal cogency Ã¢â¬â Increased through usage of multiple beginnings of grounds, structured interviews and questionnaires ( both closed and unfastened inquiries ) . The design of inquiries and study will be based on apprehension of the theory from the literature and pilot testing of the interview and questionnaire will be used to do certain inquiries are understood as intended. External cogency Ã¢â¬â Multiple instances considered to analyze whether findings can be generalised over a figure of administrations. There is no demand to do a statistical analysis of the consequences for generalization here as the attack chosen examines patterns and their effectivity. The purpose is to explicate the findings and explore generalisability through a comparing of findings with theory. Reliability Ã¢â¬â Structured interviews with inquiries derived from literature in order to analyze instances in same manner. Surveies to endorse up the interviews and obtain positions from a wider group. Questionnaires all administered at the same clip and in controlled mode, account to guarantee participants all understand research in same manner. Research Ethical motives Please see Appendix A to this proposal, the Business School Ethics Review Form. This covers the chief points to be addressed here, but in drumhead: The interviewees and study participants will be given a clear written description of the intent, range and intended results of the research. The type of information required for the research will be clearly stated as will the policy for namelessness and confidentiality. The research will be carried out in a manner that will guarantee confidentiality of the participant administrations and the single participants in the studies. The administrations which participate in the research will non be named in the thesis, nor will the interviewees and the questionnaires will be anon. . The interview inquiries and questionnaire will be designed to analyze merely the patterns of KM, no confidential merchandise or client information will be required. Even so, I have highlighted this country for possible ethical struggle in subdivision 5 of the Ethics Review Form. This is because confidential information may be discussed in the interviews and besides commented upon in the questionnaires, this information will non be included in a manner which will transgress confidentiality in the thesis. The semi-structured interviews will get down with an organizational questionnaire to derive company information such as figure of employees, figure of research staff, one-year turnover, market sector, merchandises ( type, figure of different merchandises, merchandise volume and value ) . The balance will cover a series of unfastened ended inquiries to discourse the KM patterns in order to derive an apprehension of the attack taken, the construction and effectivity, how and why certain schemes work whilst others are less effectual. Each participant will be asked to reply indistinguishable inquiries, but the order of the inquiries will non needfully be fixed as this may take away from the flow of the interview. The study is intended to supplement informations from interviews and sample more widely the patterns and single perceptual experiences in the administration. The purpose is to derive an apprehension of how the cognition schemes work and besides the sentiments and apprehension of the employees. The questionnaire will hold structured inquiries with fit responses in order to map the KM features of the administration[ 1 ]. There will besides be unfastened inquiries for participants to do remarks on the assorted facets of KM in their administration My attack to the design of the interview and study is as follows: Preliminary model built on the reappraisal of theory from academic literature prior to design of questionnaires and structured interviews Pilot interview Ã¢â¬â restructure the inquiries as necessary Pilot usage of questionnaire Ã¢â¬â restructure the inquiries as necessary Interviews Ã¢â¬â notes taken during entering cardinal words and phrases and making full record instantly after interview Survey Ã¢â¬â questionnaires explained and handed out/ collected during session Chapter 4: Findings In this subdivision the responses obtained from the questionnaire administered to the users are summarized and are presented to help treatment in subdivision 5. 4.1 Management Staff Survey A sum of 21 questionnaires were obtained for the direction staff study but out of which 3 of them were non wholly filled and had batch of compulsory inquiries unfilled hence they were non included in the analysis.

Polymers Polymer, substance consisting of large molecules that are made of many small, repeating units called monomers, or mers. The number of repeating units in one large molecule is called the degree of polymerization. Materials with a very high degree of polymerization are called high polymers. Polymers consisting of only one kind of repeating unit are called homopolymers. Copolymers are formed from several different repeating units. Most of the organic substances found in living matter, such as protein, wood, chitin, rubber, and resins, are polymers. Many synthetic materials, such as plastics, fibers, adhesives, glass, and porcelain, are also to a large extent polymeric substances. Structure of Polymers Polymers can be subdivided into three, or possibly four, structural groups. The molecules in linear polymers consist of long chains of monomers joined by bonds that are rigid to a certain degree-the monomers cannot rotate freely with respect to each other. Typical examples are polyethylene, polyvinyl alcohol, and polyvinyl chloride (PVC). Branched polymers have side chains that are attached to the chain molecule itself. Branching can be caused by impurities or by the presence of monomers that have several reactive groups. Chain polymers composed of monomers with side groups that are part of the monomers, such as polystyrene or polypropylene, are not considered branched polymers. In cross-linked polymers, two or more chains are joined together by side chains. With a small degree of cross-linking, a loose network is obtained that is essentially two dimensional. High degrees of cross-linking result in a tight three-dimensional structure. Cross-linking is usually caused by chemical reactions. An example of a two-dimensional cross-linked structure is vulcanized rubber, in which cross-links are formed by sulfur atoms. Thermosetting plastics are examples of highly cross-linked polymers; their structure is so rigid that when heated they decompose or burn rather than melt. Synthesis Two general methods exist for forming large molecules from small monomers: addition polymerization and condensation polymerization. In the chemical process called addition polymerization, monomers join together without the loss of atoms from the molecules. Some examples of addition polymers are polyethylene, polypropylene, polystyrene, polyvinyl acetate, and polytetrafluoroethylene (Teflon). In condensation polymerization, monomers join together with the simultaneous elimination of atoms or groups of atoms. Typical condensation polymers are polyamides, polyesters, and certain polyurethanes. In 1983 a new method of addition polymerization called group transfer polymerization was announced. An activating group within the molecule initiating the process transfers to the end of the growing polymer chain as individual monomers insert themselves in the group. The method has been used for acrylic plastics; it should prove applicable to other plastics as well. Bibliography Polymer, Microsoft? Encarta? 98 Encyclopedia. ? 1993-1997 Microsoft Corporation.

Profile of Demosthenes, the Greek Orator Demosthenes, renowned as a great Greek orator and statesman, was born in 384 (or 383) B.C. He died in 322. Demosthenes father, also Demosthenes, was an Athenian citizen from the deme of Paeania who died when Demosthenes was seven. His mother was named Cleobule. Demosthenes Learns to Speak Publicly The first time Demosthenes made a speech in the public assembly was a disaster. Discouraged, he was fortunate to run into an actor who helped show him what he needed to do to make his speeches compelling. To perfect the technique, he set up a routine, which he followed for months until he had mastered oratory. Plutarch on the Self-Training of Demosthenes Hereupon he built himself a place to study in underground (which was still remaining in our time), and hither he would come constantly every day to form his action and to exercise his voice, and here he would continue, oftentimes without intermission, two or three months together, shaving one half of his head, that so for shame he might not go abroad, though he desired it ever so much. - Plutarchs Demosthenes Demosthenes as Speech Writer Demosthenes was a professional speech writer or logographer. Demosthenes wrote speeches against Athenians he believed guilty of corruption. His first Philippic was in 352 (it is named for the man Demosthenes opposed, Philip of Macedonia.) Aspects of Athenian Political Life Greek men of means were expected to contribute to the polis and so Demosthenes, who became active politically in c. 356 B.C., outfitted a trireme and, as choregus at Athens, he paid for a theatrical performance. Demosthenes also fought as a hoplite at the Battle of Chaeronea in 338. Demosthenes Gains Fame as an Orator Demosthenes became an official Athenian orator. As anÃ official orator, he warned against PhilipÃ when the Macedonian king and father of Alexander the Great was beginning his conquest of Greece. Demosthenes three orations against Philip, known as the Philippics, were so bitter that today a severe speech denouncing someone is called a Philippic. Another writer of Philippics was Cicero, the Roman with whom Plutarch compares Demosthenes in Plutarchs Parallel Lives. There is also a fourth Philippic whose authenticity has been questioned. Death of Demosthenes Demosthenes troubles with the royal house of Macedon didnt end with Philips death. When Alexander insisted that the Athenian orators be delivered to him to be punished for treason, Demosthenes fled to a temple of Poseidon for sanctuary. A guard prevailed on him to come out. Realizing he was at the end of his rope, Demosthenes requested permission to write a letter. Permission was granted; the letter was written; then Demosthenes began to walk, quill pen in his mouth, to the door of the temple. He died before he reached it of a poison hed kept in his pen.

Web Server Application Attacks - Research Paper Example A command injection attack refers to an attack aimed at compromising the sensitive information featured in the back end database that supports the interactive aspects of a web application. Included under this category are issues like cross-site scripting (XSS) and Structured Query Language (SQL) injection. To curb this attack, organizations need to plan and address the security matters that pertain to their web solutions during web development or planning stages. Examples of such approaches would be to hire web application developers with proper knowledge on use of more sophisticated database capabilities like stored procedures to reside in the back end database system or the concept of data objects when writing APIs to access the database system that supports the web utilities. Equally, XSS issues can be handled by employing Model Viewer Controller (MVC) frameworks like Codeignitor while developing web applications. Such frameworks have in-built capabilities to suppress the efforts of clients who try to launch XSS attacks. A precaution taken during the development or planning of a web application is worthwhile for the reason that security issues are harder to handle once a system is deployed or implemented. The third type of attack that targets web servers is interception of unencrypted information that is channeled in communication sessions that take place between the client browsers and the servers. One way to combat this problem is to use Secure Socket Layer (SSL) in web-centered communication. SSL helps in creating an encrypted link between client-server communications. In particular, the concept uses SSL certificates (typically methods like symmetric and asymmetric encryption) to transfer sensitive information like social security numbers and credit card numbers. In the diagram, the server first sends a copy that bears its asymmetric
