Flexibility and interactivity in the context of web-based curriculum : managing change

Wong, Wai Man Joseph January 2002 (has links)
The research for this thesis involves a case study about the development of a Web-based Curriculum (WBC) in the Institute of Vocational Education of Hong Kong (IVE), abased on a WBC Change Model which provides a research framework emphasizing the importance of managing change in relation to the flexibility and interactivity in the context of the WBC. Previous research studies on Web-based education about its effectiveness on learning outcomes are found to be highly controversial. There is an assertion that the failure to fully use technology in education may be due to academic and technical divide. With regard to this, the study gives a balanced consideration to both educational and technological issues. It shows how the flexibility provided by the addition of WBC contributes to student learning and serves the new needs in the IVE. It also explains how strict control can stifle the growth of the WBC. It is found that human interactions and interactive elements of the WBC are likely to improve student performance as compared with non-human and static elements respectively. The study explores the highly complicated effects of different types of virtual interaction on student learning. The overall effect can be zero or destructive if one or more components dominate the others. If this is the case, the theory of `no-significant difference' prevails but eventually fails to reflect the true picture. The thesis provides further evidence to support the theory of additional learning benefits for different types of interaction on the Web. This research uniquely addresses the distinct characteristics of language barriers for the native Chinese students in Hong Kong especially when the Internet is primarily designed for native English users. Finally, the study explains why and how the failure of the WBC in IVE is related to the curriculum and academic structure. It depicts the conditions to support the development of a unified WBC and illustrates why the educational institutions are slow to respond to technological change. It also identifies those critical success factors related to technology and explains why a mixed strategy on information technology (IT) is suitable for effective implementation of the WBC. The results of this study have significant and far-reaching effects on the formulation of academic policy, organization structure and IT strategy especially for higher and tertiary institutions in Hong Kong.

Detecção de Botnets P2P baseada em discriminantes de sub-fluxos / P2P Botnet Detection Based on Sub-flow Statistical Discriminators (Inglês)

Marinho, Renato Rodrigues 29 November 2013 (has links)
Made available in DSpace on 2019-03-29T23:38:54Z (GMT). No. of bitstreams: 0 Previous issue date: 2013-11-29 / Botnet detection has received great attention from the academic community in recent years due to the potential threat they pose to Internet security. The P2P botnets are formed by infected computers with malicious code called zombies, capable of performing various types of malicious actions under the command of a botmaster. Its detection has received two approaches: based on network traffic or based on host behavior. This work analyzes the detection of P2P botnets based on the behavior of network traffic using J48 decision tree and Naive Bayes. The main contributions are: the use of sub-flow statistical discriminators and premature detection of known and unknown P2P botnets based on traffic C&C (command and control). Experimental results show that the approach is promising. Keywords: P2P botnet detection, command and control, sub-flow discriminators / Detecção de botnets tem recebido uma grande atenção da comunidade acadêmica nos últimos anos dada a potencial ameaça que representam para a segurança na Internet. As botnets P2P são formadas por computadores infectados por códigos maliciosos denominados zumbis, capazes de executar diversos tipos de ações maliciosas sob o comando de umbotmaster. Sua detecção tem recebido duas abordagens: baseada em tráfego de rede ou baseada em comportamento de host. Este trabalho analisa a detecção prematura de botnets P2P com base no comportamento do tráfego de rede utilizando árvore de decisão J48 e Naive Bayes. As principais contribuições deste trabalho estão relacionadas à utilização de discriminantes estatísticos de sub-fluxo e a detecção de botnets P2P conhecidas e desconhecidas com base no tráfego C&C (comando e controle). Os resultados experimentais mostram que a abordagem é bastante promissora. Palavras-chave: Detecção e botnets P2P, comando e controle, discriminantes de sub- fluxo

<p>The purpose of this study is to provide the view on the online advertising’s characteristics during the present financial crisis in Sweden. To achieve the purpose, multiple case study of four main Swedish banks is used with the predominance of descriptive method. The main finding of this study is close interaction between the advertising character and market trends impact. This main observation has a great impact on the character of the analysis and affects almost every functional aspect of the advertising. Besides that, also five other main observations were made. Following them, it is especially worth to mention that advertising can be a source of competitiveness, a way of differentiation or a way of conditioning customer. From all the study findings, clear image of ads typical features, functions and roles in the banks’ prosperity arises.</p>
