In today?s society the average person is flooded by information from everywhere. This is in particular the case when using the Internet; consider for a moment the fact that a decent search engine at this moment scans 8 058 million homepages. For a user that repeatedly comes back to the same site, the case is often that they know what they are looking for. The problem is to isolate the important information from all the other information embedding it.We would like to state that we have found one possible solution to this problem, where the user himself can define what information he is looking for at a specific server, then scan the server when visiting it with his browser.

The purpose with this essay is to study police students perception of men?s and women?s role taking and behavior in a group. The question that is presented is if a group?s efficiency can depend on which gender the members of the group have. There are many theories about the concept male and female and the meaning of these words.

The aim of this study was to find out if hypertext structure has any relevance for the efficiency of information retrieval. An experiment, in which three variants of hypertext structure were compared, was carried out in the autumn of 1998. Three websites with different structures were constructed for this purpose: a sequential version, a hierarchical version and a webcluster version. 44 subjects, all students at the University of Lund, were randomly divided into three groups. Subjects were requiered to answer a number of questions using one of the three versions.

With the purpose of finding the motives behind use, production and reuse of Open Educational Resources (OER), the writer has conducted a qualitative survey. The three main questions in this two years master?s thesis are:? Why do people use others? unmodified OER?? Why do people produce OER?? Why do people alter and reuse OER?The theoretic framework is built around Manuel Castells? network society, with its social and efficiency seeking dimension, along with the Knowledge commons. Some pedagogy is included as well.A web survey was distributed to 796 users of the Connexions OER repository. 95 responses were received.

The purpose of this essay was to examine six high school welfare officers' experiences and work with students suffering from social phobia and discuss the welfare officers' view on social phobia from a psychiatric, cognitive and a knowledge theory. The study consists of qualitative interviews with welfare officers from several different high schools and attempts to answer the following questions: What previous experiences do welfare officers have of students with social phobia? How do welfare officers become aware of students with symptoms of social phobia and bring forth their problems? How do welfare officers describe their social work with students suffering from social phobia?The welfare officers' experiences of students with social phobia varied but turned out to be less salient than the amount of research in the area would suggest. The theoretical knowledge also varied, as did the acquiring and use of theory. These findings were then analysed on the basis of Rosmari Eliassons thoughts on knowledge, leading to the conclusion that the interviewed welfare officers do not construct their work on praxis-knowledge.

The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

This thesis investigates in which way principles and theories of usability is revelant when evaluating interactive systems for children aged 10-12. It also investigates whether there are specific factors that you should keep in mind while developing interactive products for the targeted group.The results of the qualitative study shows that priciples and theories of usability is relevant when evaluating interactive systems for the targeted group. However there is one concept that is more significant than the others. Our study shows that our targeted group is sensitive to time-consuming activities such as loading times etc. which has to do with the efficiency of the system.

With the end of the Cold War the number of conflicts where the United Nations have intervened has increased dramatically. This has entailed a need for a burden-sharing between the UN and regional organizations regarding management of conflicts. The aim of this study is to make a comparative analysis of the effectiveness and the efficiency in the efforts undertaken by ECOWAS and the UN during the civil war in Sierra Leone, through using theories on conflict resolution and the advantages of regional organizations in conflict resolution.My conclusion is that both ECOWAS and the UN were quite successful in managing the conflict and had an impact on the resolution of the war, although both peace operations suffered from internal problems. ECOWAS was effective in managing the conflict and in its mediating efforts as an insider from the region. The UN was more efficient in managing to attain their goals.

As a part of Göteborg Energi?s work towards a smarter electric grid, the company has chosen to investigate the possibilities of automation in their middle voltage grid. In Europe, there are example cases where these technologies already are installed which many articles on the CIRED conference 2011 proved. Netcontrol Oy in Finland has, together with Tekla, created an automated SCADA system that Vattenfall in Finland today uses. The grid mainly consists of 10 kV open loop fed city grid and this automation is mainly designed for this type of grid.

sustainable development by reducing the energy use by EU:s directive of energy efficiency and the UN Convention. The second purpose is to present the technical solutions regarding ventilation and heating system that is being used in passive houses. This was done using 8 passive houses, 4 germany and 4 swedish passive houses. Even the international and Swedish system requirements for passive houses have been addressed in this project. The goal was also to explain how and why the mechanical system in passive houses has developed to the technology used today.

The purpose of this thesis is to shed light on a present trend of professionalization in Swedish local environmental politics, which have recently seen a decline in active participation of the citizens in favor of an increased governmental regulation. With the aim to closer investigate this relatively new phenomenon, the paper is a qualitative single case-study of environmental policies in the Swedish municipality of Karlskrona. In this case, the municipality is obviously balancing between regarding the interests of the national level and the interests of its own citizens at the same time. This motivates the use of system-theory, and relates to the classical political paradox between participation and efficiency which is also a present theme in the paper.This text-analysis based on interviews with personnel and documents from the municipality shows a visible trend of professionalization in the local politics of the municipality of Karlskrona, from a large grade of participation and a strong bottom-up approach in the days of Agenda 21 to now being more strongly top-down defined by national environmental objectives and principally operated on a professional level..

The Swedish National Heritage Board (RAÄ) is the agency of the Swedish government responsible for heritage and historic environment issues. During the last couple of years the agency has implemented a new management control system, the balanced scorecard, originally developed for profit driven organizations. Organizations within the public sector have other objectives than profit seeking organizations, and there have been difficulties in applying the balanced scorecard model in the public sector. Therefore we find it interesting to examine the reasons behind these difficulties and believe that some answers can be found in the identification process of the balanced scorecard. Therefore we aim to perform a case study of RAÄ and explain how the identification process of the components of their balanced scorecard can affect further usage of the model as a management control tool.

Att bara slänga ihop ett användargränssnitt är inte särskilt svårt. Det svåra ligger i att göra det på ett sådant sätt att användaren känner tillförlitlighet och förtroende för det. Genom att titta på teorier om hur vi uppfattar och tar till oss information och hur information kan anpassas för att nå ut till målgruppen, kan man få fram ett gränssnitt som uppfyller några kvalitativa komponenter som utgör användbarhet; learnability, efficiency, memorability, errors och satisfaction. Informationsdesign ger oss verktygen för att uppfylla dessa krav. Att formge efter gestaltlagar, organisera med tydlig struktur och genomarbetad taxonomi med tydliga etiketter, skriva tydliga trovärdiga och språkanpassade texter och minimera bruset genom att ta bort överflödig information bidrar till god informationsdesign.

AB Smådelar är ett företag som tar hållbarhet på allvar. Man har nyligen presenterat sin första hållbarhetsredovisning och vill inför framtiden förbättra sig ytterligare avseende logistiken mot underleverantörerna. Då det finns ett fokus på hållbarhet vill AB Smådelar inte att de logistiska förbättringarna ska påverka Triple bottom line negativt, varför en modell har konstruerats för att kunna testa förbättringsförslagens inverkan före implementering. Studien är kvalitativ med abduktiv ansats och har utgångspunkt i semistrukturerade intervjuer. Syftet är att göra en nulägesanalys för att hitta förbättringsområden och föreslå åtgärder som kan effektivisera logistiken med samtidig positiv effekt på både ekonomisk, miljömässig och social hållbarhet. Syftet är också att ta fram en enkel matrismodell för att strukturera och testa de planerade logistiska förändringarnas effekt över hela Triple bottom line. Utifrån nulägesbeskrivningen har grundläggande strategi för logistiskt arbete avhandlats, liksom Paretos princip, totalkostnadsmodellen, komplexiteter och balanced scorecard.

The purpose with this essay is to investigate whether the legal capital can be justified as creditor protection and whether the legal capital prevent entrepreneurship.Historically the legal capital has been justified by means of creditor protection. Nowdays the development within EU rather reduces or abolish the legal capital. Sweden has recently, 1 of April 2010, reduced the legal capital from 100 000 Swedish crowns to 50 000 Swedish crowns. In the preparatory work it has been admitted that the legal capital does not in reality offer creditors much protection. Although the lawmaker decides to retain the legal capital and justifies the legal capitals existence with the argument that involuntary creditors has the need of the legal capital.
