Informationshantering kring nationella prov i matematik på gymnasiet

David, Gabriella January 2011 (has links)
This work studied the information flow and information handling among different parties. The study focused on how educational materials on national tests from The Swedish National Agency for Education is managed by school principals and teachers and how the information is passed on to students. The data material was based on observations and interviews at two different high schools. Six teachers and their classes and principals participated in the study. The Agency was also interviewed. The results showed that opinions on the role of the national test varies between different teachers and the Agency. The study also showed that the dissemination of information in the schools is inadequate, information documents do not reach their target audience, and those who have access to the information do not read enough. This is partly due to lack of follow-up from the responsibles at the schools, but also teachers who do not seek out information that is available themselves. These shortcomings result in teachers carrying out national tests with their classes without being properly briefed, which could have consequences for both the students and the entire test system.

Informationsspridning genom olika kanaler och medium i en organisation / Dissemination of information through various channels and media within an organization

Jernberg, Adam January 2016 (has links)
I dag så sprids information på ett helt annat sätt än vad den gjorde för både fem och tjugo år sedan och i takt med att tekniken utvecklas så förändras vårt sätt att ta del av information. På många arbetsplatser så är informationsspridning en central del av verksamheten, och tidigare forskning har visat att effektiv spridning av information ökar möjligheterna för företaget att utvecklas. Denna studie har undersökt hur information bör kommuniceras till medarbetare inom en organisation. En åtskillnad mellan kanal och medium har gjort det möjligt att särskilja hur information meddelas och hur den presenteras. Detta har lett till ett resultat som visar på att medarbetare på företaget föredrar att få information presenterad för sig muntligt, och att det finns en viss skillnad när information skall meddelas. Studien grundar sig i en fallstudie inom ett företag som är verksamt inom el- och teknikbranschen. För att kunna generera en tydlig bild av hur informationsspridningen ser ut på företaget så har en kvalitativ intervju genomförts, vilket har kopplats samman med en mer specifik enkätundersökning. / Today information dissemination is completely different comparing to both five and twenty years ago, and as the technology develops, so does our way of accessing information. In many workplaces information dissemination is a key process and previous research has shown that effective information sharing increases the potential for the company to develop. This study has examined how information ought to be communicated to cowerkers within a company. A distinction has been made between channel and medium and has made it possible to determine how information is being notified and how information is being presented. This has led to a result showing that coworkers prefers information being presented orally, and that it is a difference when the same information is being notified. The study is based on a case study within a company active in the electrical and engineering industry. A qualitative interview and a quantitative survey has made it possible to generate a clear picture of how the information dissemination looks like in the specified company.

Adaptive dissemination of network state knowledge in structured peer-to-peer networks

Hajiarabderkani, Masih January 2015 (has links)
One of the fundamental challenges in building Peer-to-Peer (P2P) applications is to locate resources across a dynamic set of nodes without centralised servers. Structured overlay networks solve this challenge by proving a key-based routing (KBR) layer that maps keys to nodes. The performance of KBR is strongly influenced by the dynamic and unpredictable conditions of P2P environments. To cope with such conditions a node must maintain its routing state. Routing state maintenance directly influences both lookup latency and bandwidth consumption. The more vigorously that state information is disseminated between nodes, the greater the accuracy and completeness of the routing state and the lower the lookup latency, but the more bandwidth that is consumed. Existing structured P2P overlays provide a set of configuration parameters that can be used to tune the trade-off between lookup latency and bandwidth consumption. However, the scale and complexity of the configuration space makes the overlays difficult to optimise. Further, it is increasingly difficult to design adaptive overlays that can cope with the ever increasing complexity of P2P environments. This thesis is motivated by the vision that adaptive P2P systems of tomorrow, would not only optimise their own parameters, but also generate and adapt their own design. This thesis studies the effects of using an adaptive technique to automatically adapt state dissemination cost and lookup latency in structured overlays under churn. In contrast to previous adaptive approaches, this work investigates the algorithmic adaptation of the fundamental data dissemination protocol rather than tuning the parameter values of a protocol with fixed design. This work illustrates that such a technique can be used to design parameter-free structured overlays that outperform other structured overlays with fixed design such as Chord in terms of lookup latency, bandwidth consumption and lookup correctness. A large amount of experimentation was performed, more than the space allows to report. This thesis presents a set of key findings.

O rádio é um excelente veículo para a disseminação do conhe-cimento em saúde. O rádio pela internet é uma alternativa que amplia esta dis-seminação. Experiências de comunicação em saúde usando rádio na internet têm sido apresentadas na literatura cinzenta, constituindo base de conhecimento para a construção de modelos. Em particular, estas experiências servem de refe-rência para ampliar as atividades de comunicação da UNIFESP na sua relação com a sociedade para a disseminação de conhecimento em saúde. OBJETI-VOS. O objetivo deste trabalho é construir e avaliar um modelo para a dissemi-nação do conhecimento em saúde baseado em rádio na internet. MÉTODOS. A pesquisa foi realizada em seis etapas: 1) pesquisa bibliográfica sobre rádio e seu papel educativo no Brasil; 2) descrição de projetos já desenvolvidos sobre rádio na educação e rádio na saúde; 3) revisão sistemática sobre rádio e promoção da saúde; 4) experimento com alunos da Universidade Aberta à Terceira Idade (U-ATI), da UNIFESP; 5) construção de um modelo de rádio na internet, e 6) avalia-ção do modelo construído. RESULTADOS. A pesquisa bibliográfica e o levanta-mento de projetos já desenvolvidos serviram como base para a construção do modelo proposto. O experimento com alunos da UATI forneceu dados para a produção de conteúdo para terceira idade. A revisão sistemática comprovou a hipótese de que o rádio é um excelente veículo para a disseminação do conhe-cimento em saúde. O portal web foi disponibilizado publicamente (http://www.radiosaude.unifesp.br) com 30 áudios resultando aprovação média de credibilidade e clareza (100,0%), utilidade (96,8%), aprovação imediata (87,0%) e usabilidade SUS (86,5%). CONCLUSÕES. Um modelo de rádio na internet para disseminação de conhecimento em saúde, denominado Rádio U-NIFESP Web, foi proposto e aprovado por especialistas e público leigo. Este pro-jeto possibilita uma ampliação do papel social da UNIFESP na disseminação do conhecimento em saúde. / INTRODUCTION. Radio is an effective medium for health knowledge dissemina-tion. Internet radio is an alternative that can help expanding this dissemination. The gray literature describes experiences in health communication using internet radio that can be a prime body of knowledge for model construction. These expe-riences are particularly valuable as a point of reference for expanding the Federal University of São Paulo (UNIFESP) communication activities of disseminating health knowledge to the Brazilian community. OBJECTIVES. To construct and evaluate an internet-based radio model for health knowledge dissemination. ME-THODS. The study was carried out in six steps: 1) literature review of studies on radio as an educational medium in Brazil; 2) search of reports of previous projects developed on radio and education and radio and health; 3) systematic review on radio and health promotion; 4) trial with students of the Open Universi-ty of the Third Age (UATI) at UNIFESP; 5) construction of an internet-based radio model, and 6) evaluation of the model constructed. RESULTS. The literature re-view and reports of previous projects served as a base for the construction of the proposed model. The trial with UATI students provided data for the production of contents focusing on the third age. The systematic review confirmed the hypo-thesis that radio is an effective vehicle for health knowledge dissemination. The web portal was made available to the audience (http://www.radiosaude.unifesp.br) with 30 audio products and the average ap-proval rates were as follows: credibility and comprehensibility, 100.0%; useful-ness, 96.8%; immediate approval, 87.0%; and SUS usability, 86.5%. CONCLU-SIONS. An internet-based radio model for health knowledge dissemination, known as Radio UNIFESP Web, was proposed and approved by expert and lay audiences. This project allows to expanding UNIFESP’s social function as health knowledge disseminator. / TEDE / BV UNIFESP: Teses e dissertações
