Resource Centre Sites: The New Gatekeepers of the Web?Bruns, Axel Unknown Date (has links)
This thesis introduces and analyses the emerging Website genre of Resource Centre Sites. RCSs are sites which combine news, rumours and background information as well as community discussion and commentary on their chosen topic, and frequently serve as a first point of entry for readers interested in learning more about the field. They also offer spaces for virtual communities of specialists or enthusiasts to emerge, who in the process and as a product of their interaction on these sites collate detailed resource collections and hyperlink directories for their fields of interest. Therefore, Resource Centre Sites significantly involve their users as content contributors and producers, turning them into what is here termed produsers of the site. Aiming to evaluate all the content relevant to their field that is becoming available online, and to coopt or at least link to this information from the news and resources collection that is a central part of the RCS, Resource Centre Site produsers engage in an adaptation of both traditional journalistic gatekeeping methodologies and librarianly resource collection approaches to the Web environment: in the absence of gates to keep online, they have become gatewatchers, observing the publication of news and information in other sources and publicising its existence through their own sites. Their operation is studied here through a number of case studies of major existing Resource Centre Sites from various fields of interest. These sites are analysed both based on their available Web content, and using background information obtained in a series of email interviews with RCS creators. In combination, this offers insights into the operating philosophies of sites and site editors, and provides an opportunity to assess to what extent these ideas have been translated into everyday practice. Chapter 1 provides an overview of past and current theoretical views of the Web in an effort to evaluate their suitability for the current study. Older approaches positing an abstract ideal form of hypertext are rejected in favour of a direct engagement with the World Wide Web as the now dominant mode of hypertextuality. Chapter 2 outlines the principles of gatewatching in contrast to traditional methods of evaluating news and information as they exist in journalistic media and archival institutions, and investigates the effects such gatewatching practices may have on editors and users. Chapter 3 describes the overall characteristics of Resource Centre Sites as a genre of Web publications. It notes the special role site users play in the operation of such sites (in their new role as produsers), and distinguishes the RCS genre from similar Website models such as portals and cybermediaries. Chapter 4 observes the everyday operation of such Websites in practice, using case studies of major existing Resource Centre Sites including Slashdot, MediaChannel and CountingDown, and interviews with their creators. (These interviews are included in full in the Appendix.) This analysis works with both a synchronic view to the variety of topics existing Resource Centre Sites are able to address, and a diachronic view to the evolution of proto-RCSs (such as enthusiast community or online advocacy sites) into fully-featured Resource Centre Sites. Finally, based on this analysis, Chapter 5 is then able to point out some of the implications and effects that increasing use of this media form may have on its users and the network of news and information publications on- and offline, and to indicate the potential for further developments of the site genre.

As células-tronco como tema gerador para o ensino voltado a divulgação científica e a aprendizagem de Biologia / Stem cells as generator theme for teaching destined to scientific divulgation and Biology learningCestaro, Débora Cristina 07 July 2016 (has links)
As inovações tecnológicas mudaram o mundo, as formas de interação e o acesso à informação e ao conhecimento, reivindicando mudanças também na educação. Documentos brasileiros como os Parâmetros Curriculares Nacionais (PCN), suas complementações (PCN+) e as Diretrizes Curriculares Nacionais passaram a propor um ensino mais contextualizado e condizente com os novos anseios da sociedade. A formação de cidadãos críticos e o “educar para a vida” tornaram-se temas recorrentes nos documentos, textos sobre educação e nas coordenações dos colégios. No entanto, o objetivo de muitos alunos do ensino médio e de seus familiares continuou sendo a aprovação no vestibular e a obtenção de um bom escore no Exame Nacional do Ensino Médio. Mediante o atual contexto escolar, com o propósito de divulgar a ciência brasileira e produzir ferramentas que facilitem o processo de ensino-aprendizagem foi proposto esse trabalho. Através da interação com o Laboratório de Biologia Básica de Células-tronco (LABCET) do Instituto Carlos Chagas/FioCruz, as células-tronco foram utilizadas como tema gerador para a produção de um objeto educacional que visa desmitificar a ideia que a biologia prioriza a descrição e a memorização, trazendo três sequências didáticas desenvolvidas acerca dos conteúdos de embriologia, biotecnologia e bioética e expressão gênica. Estruturado a partir da metodologia dos Momentos Pedagógicos estas sequências didáticas partem de problematizações, passam pela organização do conhecimento e terminam na aplicação deste. Estas atividades foram disponibilizadas num portal também desenvolvido neste trabalho, intitulado “O que a Ciência sabe”, que conta com materiais complementares destinados a alunos do Ensino Médio e professores de Biologia. / Technological innovations changed the world, ways of interaction and access to information and knowledge, requiring changes in education also. Brazilian documents such as Parâmetros Curriculares Nacionais (PCN), its complements (PCN+) and Diretrizes Curriculares Nacionais have been proposing a more contextualized teaching and consistent with the new desires of society. A critic citizen formation and “teaching for life” have become recurrent themes in documents, publications about education and schools’ pedagogical staff. However, the objective of many high school students and their families continued to be college acceptance and achievement of a good Exame Nacional de Ensino Médio score. By the current educational context, this study was proposed with the purpose of divulging Brazilian science e producing tools that facilitate the teaching-learning process. Through interaction with the Laboratório de Biologia Básica de Células-tronco (LABCET) of Carlos Chagas Institute/FioCruz, stem cells were utilized as generator theme for the production of an educational object that aims for demystification of the idea that biology prioritize description and memorization, bringing three didactic sequences developed on the subjects of biotechnology and bioethics, embryology and genic expression. Structured according to Pedagogical Moments methodology, these didactic sequences initiate by problematizations, pass through knowledge organization and end at its application. These activities were made available in a portal also developed in this study, entitled “O que a Ciência sabe” (”What Science knows”), that is equipped with complementary materials destined for high school students e Biology teachers.

A new framework for a technological perspective of knowledge managementBotha, Antonie Christoffel 26 June 2008 (has links)
Rapid change is a defining characteristic of our modern society. This has huge impact on society, governments, and businesses. Businesses are forced to fundamentally transform themselves to survive in a challenging economy. Transformation implies change in the way business is conducted, in the way people perform their contribution to the organisation, and in the way the organisation perceives and manages its vital assets – which increasingly are built around the key assets of intellectual capital and knowledge. The latest management tool and realisation of how to respond to the challenges of the economy in the new millennium, is the idea of "knowledge management" (KM). In this study we have focused on synthesising the many confusing points of view about the subject area, such as: <ul><li> a. different focus points or perspectives; </li><li> b. different definitions and positioning of the subject; as well as</li><li> c. a bewildering number of definitions of what knowledge is and what KM entails.</li></ul> There exists a too blurred distinction in popular-magazine-like sources about this area between subjects and concepts such as: knowledge versus information versus data; the difference between information management and knowledge management; tools available to tackle the issues in this field of study and practice; and the role technology plays versus the huge hype from some journalists and within the vendor community. Today there appears to be a lack of a coherent set of frameworks to abstract, comprehend, and explain this subject area; let alone to build successful systems and technologies with which to apply KM. The study is comprised of two major parts:<ul><li> 1. In the first part the study investigates the concepts, elements, drivers, and challenges related to KM. A set of models for comprehending these issues and notions is contributed as we considered intellectual capital, organizational learning, communities of practice, and best practices. </li><li> 2. The second part focuses on the technology perspective of KM. Although KM is primarily concerned with non-technical issues this study concentrates on the technical issues and challenges. A new technology framework for KM is proposed to position and relate the different KM technologies as well as the two key applications of KM, namely knowledge portals and knowledge discovery (including text mining). </li></ul> It is concluded that KM and related concepts and notions need to be understood firmly as well as effectively positioned and employed to support the modern business organisation in its quest to survive and grow. The main thesis is that KM technology is a necessary but insufficient prerequisite and a key enabler for successful KM in a rapidly changing business environment. / Thesis (PhD (Computer Science))--University of Pretoria, 2010. / Computer Science / unrestricted

Dear Creativity, I´ll do my best / The endless choices of creativityTherése, Grabs January 2020 (has links)
I mitt kandidatprojekt har jag arbetat med temat ”att utvecklas som kreatör” och hur man som skapare konstant ifrågasätter sig själv men också blir kritiserad av sin omgivning. Det handlar om att fortsätta följa sin passion trots osäkerhet eller ångest. Som kreatör ställs vi konstant inför val, stora som små, i vårt skapande och det är lätt att bli överväldigad av alla oskrivna regler, men också alla vägar och möjligheter. Jag har valt att gestalta detta med en animerad kortfilm. Att projektet tog form just inom filmmediet beror på att min största inspiration kommer från filmens värld och jag har länge varit intresserad av att utforska animation som berättarform. Jag har huvudsakligen jobbat digitalt, dels för att jag vill utveckla mina kunskaper inom det digitala, men också för att det under omständigheterna med den pågående Coronapandemin var mer praktiskt när jag inte hade lika fri tillgång till skolans utrustning som i vanliga fall.

Scalable Multimedia Learning: From local eLectures to global OpencastKetterl, Markus 27 March 2014 (has links)
Universities want to go where the learners are to share their rich scientific and intellectual knowledge beyond the walls of the academy and to expand the boundaries of the classroom. This desire has become a critical need, as the worldwide economy adjusts to globalization and the need for advanced education and training becomes ever more critical. Unfortunately, the work of creating, processing, distributing and using quality multimedia learning content is expensive and technically challenging. The work combines research results, lessons learned and usage findings in the presentation of a fully open source based scalable lecture capture solution, that is useful in the heterogenous computing landscape of today’s universities and learning institutes. Especially implemented user facing applications and components are being addressed, which enable lecturers, faculty and students to record, analyze and subsequently re-use the recorded multimedia learning material in multiple and attractive ways across devices and distribution platforms.

Design, development and experimentation of a discovery service with multi-level matchingPileththuwasan Gallege, Lahiru Sandakith 20 November 2013 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / The contribution of this thesis focuses on addressing the challenges of improving and integrating the UniFrame Discovery Service (URDS) and Multi-level Matching (MLM) concepts. The objective was to find enhancements for both URDS and MLM and address the need of a comprehensive discovery service which goes beyond simple attribute based matching. It presents a detailed discussion on developing an enhanced version of URDS with MLM (proURDS). After implementing proURDS, the thesis includes details of experiments with different deployments of URDS components and different configurations of MLM. The experiments and analysis were carried out using proURDS produced MLM contracts. The proURDS referred to a public dataset called QWS dataset. This dataset includes actual information of software components (i.e., web services), which were harvested from the Internet. The proURDS implements the different matching operations as independent operators at each level of matching (i.e., General, Syntactic, Semantic, Synchronization, and QoS). Finally, a case study was carried out with the deployed proURDS. The case study addresses real world component discovery requirements from the earth science domain. It uses the contracts collected from public portals which provide geographical and weather related data.

The worlds between, above and below : "growing up" and "falling down" in Alice in Wonderland and StardustPotter, Mary-Anne 2012 November 1900 (has links)
The purpose of my dissertation is to conduct an intertextual study of two fantasy texts — Alice in Wonderland by Victorian author Lewis Carroll, and Stardust by postmodern fantasy author Neil Gaiman — and their filmic re-visionings by Tim Burton and Matthew Vaughn respectively. In scrutinising these texts, drawing on insights from feminist, children’s literature and intertextual theorists, the actions of ‘growing up’ and ‘falling down’ are shown to be indicative of a paradoxical becoming of the text’s central female protagonists, Alice and Yvaine. The social mechanisms of the Victorian age that educate the girl-child into becoming accepting of their domestic roles ultimately alienate her from her true state of being. While she may garner some sense of importance within the imaginary realms of fantasy narratives, as these female protagonists demonstrate, she is reduced to the position of submissive in reality – in ‘growing up’, she must assume a ‘fallen down’ state in relation to the male. / English Studies / M.A. (English)
