Su principal misión es la de modernizar la gestión pública a través de proyectos que desarrollen las Tecnologías, la Información y las Comunicaciones (TIC s) a nivel Gubernamental. Por esa vía se desarrolla la Red Nacional de Internet (RNI), proyecto emblemático del Gobierno Nacional y de gran impacto social, garantizando con su ejecución una reducción en la brecha digital de la República de Panamá. Este enfoque se manifiesta debido a que en el país, tanto en el interior como en las áreas urbanas, por falta de recursos, accesibilidad y otros elementos, los ciudadanos no pueden obtener un servicio de internet, resultando en individuos con limitantes en el marco de la investigación académica (a nivel de secundaria, universidad, etc.), como también en lo social, cultural y económico, lo cual conlleva a quedarse resagados en la denominada sociedad del conocimiento. ····· 10361117077

Poco a poco se tomó conciencia de la importancia de un buen modo de organizar la información en un sitio web. Y es que, más allá del conocimiento previo de cada usuario, lo que mantiene a una persona dentro de un proyecto e-learning es el nivel de compromiso visual y de la interactividad que se haya logrado en su diseño. Para asegurarnos que una aplicación cumple con los niveles de usabilidad exigidos, es necesario disponer de una metodología para descubrir las necesidades y dificultades con los que el usuario se encuentra. Actualmente faltan propuestas para identificar los principios básicos de usabilidad en una aplicación educativa en línea.

Cumulative licensing (also known as pay-as-you-go licensing) is a type of software licensing which allows users to pay fees based on the actual usage of the software as opposed to traditional licenses where users are required to purchase a license to use the software regardless of the usage of the computing resources. The interest in applying Cumulative licensing has been increasing, especially in SaaS applications. The current SaaS pricing model of many SaaS vendors is implemented as customers paying fixed fee per month. Many customers are not satisfied with the current pricing model and are requesting to pay according to the actual usage of the SaaS application. In this thesis, Cumulative licensing is implemented on SaaS applications as customers pay for the features of the software that they utilize (Feature-Based approach). ····· 10361115593

Kuwaiti online journalism became the source for instant updated information during the disputes. Three different tools (survey, online content analysis & interviews) were used to determine the effect of online journalism on journalist`s practices and the freedom of the press in Kuwait, focusing on the most popular Kuwaiti personal writers` sites, weblogs & forums. The results show that online journalism affected journalist`s practices but did not replace the traditional practices. The language of online journalism took a different direction from the local press with more freedom to write, discuss, and share ideas online with less fear of government retribution. What was considered a taboo red line in the local press became an acceptable green line online. ····· 10361115343

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Today open source philosophy points the way to innovations arising from the adoption of new models for distributing know-how and exploiting intellectual capital. Growing interest in knowledge management has led to increased attention being paid to social network analysis as a tool for mapping the structure and nature of shared information. However, despite the knowledge-intensive nature of resource-based view (RBV), social network analyses of the R&D function remain relatively rare. This paper discusses the role of networks in the development, exchange and dissemination of knowledge exploitable by companies in search of innovation. An empirical study using social network analysis is presented to give evidence to theoretical models. This takes into account both static and dynamic network variables, and debates motivational drivers behind members` commitment to social networking. The implications for business world are clear: companies have to rethink traditional approach to innovation, revising their model to knowledge creation, and learn to wisely leverage networked intellectual capital and spare time commoditization. ····· 10361114651

This book contains survey of various methods used for enhancing the performance of the web. This book also contains description of some newly proposed methods for accessing the web almost instantly. A browser aware clustered cache sharing architecture is proposed for reducing the web traffic and latency. In this architecture, proxy servers are grouped into clusters and one proxy is elected as coordinator for each cluster. The coordinator proxy is elected in distributed manner to survive from failures. A dynamic pre-fetching technique is proposed in which web caching and pre-fetching techniques are integrated together to save memory space and reduce response time. An adaptive traffic reduction technique is proposed for providing an efficient access to the web sites by utilizing the existing web traffic and latency reduction methods effectively. Using adaptive traffic reduction technique, cache hit ratio is increased and latency is very much reduced. ····· 10361113266

Many search engines come out to help users finding their desired information but search engines still return hundreds of irrelevant web pages that do not fulfill the user`s query. Several search engines use clustering to group documents that are relevant to the user`s query before returning them to the user, but there is no document clustering algorithm that has an accuracy that can prevent retrieving irrelevant documents. In this research, the researchers have introduced a new technique to enhance cluster quality by using user browsing time as an implicit measure of user feedback, rather than using explicit user feedback as in previous research and techniques. The major contributions of this work are: investigating user browsing time as an implicit measure of user feedback and proving its efficiency, enhancing cluster quality by using a new clustering technique that is based on user browsing time, and developing a system that tests the validity of the proposed technique. ····· 10361113240

Der mit der Verbreitung des Internets stetig wachsende Datenfluss und die Möglichkeit zur einfachen Kommunikation zwischen kritischen Stakeholdern eines Unternehmens führen zu erhöhten Informationsansprüchen. Durch internetbasierte Kommunikation bietet sich Unternehmen aber nicht nur ein Risiko, sondern auch die große Chance, im Rahmen ihrer Informationspolitik über die Geschäftsberichterstattung hinaus mit einer umfassenden Nachhaltigkeitsberichterstattung alle ihre Stakeholder zu adressieren und einen aktiven Dialog zu führen, um so ihr öffentliches Profil zu schärfen und sich von Mitbewerbern zu differenzieren. Im Rahmen dieser Arbeit wurde untersucht, wie sich ein kontinuierlicher Dialog zwischen Unternehmen und Stakeholdern im Internet auf Grundlage einer umfassenden Nachhaltigkeitsberichterstattung führen lässt. Dazu wurde analysiert, wie sich das `Web of people`, das sog. Web 2.0 nutzen lässt, um Netzwerkeffekte zu nutzen und die Nachhaltigkeitsberichterstattung gemeinsam mit den Lesern stetig zu verbessern. Um eine Übertragbarkeit auf vorhandene Firmenstrukturen zu gewährleisten, wurden die Anforderungen an die technischen Grundlagen in einer Referenzarchitektur zusammengetragen, die in STORM beispielhaft implementiert wurden. So finden nicht nur bereits berichterstattendene Unternehmen ein Modell, wie sie ihre Systeme an die neuen Herausforderungen einer dialogbasierten Berichterstattung anpassen können, auch bislang nicht teilnehmende Unternehmen finden technische und inhaltliche Vorgaben, um schnell partizipieren zu können. Darüber hinaus wurde für einen transparenten, abseits vom Unternehmen stattfindenden stakeholderinternen Dialog mit GreenBee eine weitere Plattform geschaffen, in dem der Nachhaltigkeitsgedanke gefestigt wird und Unternehmen unabhängig für ihre Leistungen bewertet werden können. Durch diese Dissertation wurden somit die Grundlagen für einen dauerhaften, nachhaltigkeitsorientierten Dialog geschaffen - von Unternehmen zu Stakeholdern, von Stakeholdern zu Unternehmen und zwischen den Stakeholdern selbst.

Proposed cookies based and an inverse cookie based virtual password authentication protocols are very effective to thwart online dictionary attacks because the computation cost of login on to the web server increases exponentially with each login failure for an attacker. We proposed an efficient SSO password based two-server architecture in which the user has to login once to get a valid ticket. Improvements to several static and dynamic identity based authentication protocols have also been suggested. The proposed dynamic identity based authentication protocols aim to provide the privacy to the user`s identity so that users are anonymous in communication channel. Also the concept of two- tier authentication for the client makes it difficult for an attacker to guess out the information pertaining to password and ticket.
