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.

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.

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.
