Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

The papers purpose is to examine how the Botkyrka and Huddinge municipalities implement their juvenile law offenders' programs. The paper briefly and concisely outlines the history of juvenile offenders and the social services programs dealing with them. We focus on how two municipalities?, Huddinge and Botkyrka, implement these programs. The municipalities belong to the same judicial district,?Södertörns tingsrätt?.

Nya typer av krigföring, så som COIN-operationer (Counter insurgency), ställer nya krav på flygstridskrafterna. Utvecklingen av det bemannade stridsflyget har, om man jämför med UAV (Unmanned Aerial Vehicle), trots detta stått relativt stilla. Obemannat stridsflyg har samtidigt utvecklat förmågor som gör funktionen till en värdig konkurrent på det moderna slagfältet. Syftet med denna uppsats är att undersöka huruvida obemannat stridsflyg kan överta det bemannade stridsflygets plats inom ramen för COIN-operationer. Detta avser jag uppnå genom att undersöka hur väl de båda funktionerna svarar uppmot de krav som ställs på ett stridsflygplan i en operation med inslag av COIN.

Studien syftade till att undersöka om det finns samband mellan conscientiousness, Locus of Control och arbetsmotivation samt om ålder och anställningslängd predicerar en del av ar-betsmotivation. Studien omfattade 63 anställda (28 kvinnor och 35 män) på ett telekommuni-kationsföretag i Sverige. För att studera conscientiousness användes ett egenformulerat test med god intern homogenitet, Cronbachs alfa = 0,85. För att mäta Locus of Control och ar-betsmotivation användes redan konstruerade test med god validitet och reliabilitet, skapade av Rotter (1966) och Cammann, Fichman, Jenkins och Klesh (i Bowling & Hammond 2008). I den statistiska prövningen användes både bivariat korrelation i form av Spearmans rho och MRA-standard och hierarkisk.

The purpose of this master?s thesis is to study an electronic reference service from a user perspective. By qualitative interviews with eight students the thesis examines their information behaviour, why and when they use the service, the user?s experiences of the service and the communication with the librarian. The users have all used the Swedish electronic reference service Fråga biblioteket ? Forskningsbibliotek.

Social control in different forms has existed in all known societies. This control has taken different shapes and expressions. In older smaller communities there was a collective control among the citizens. In modern societies the state is trying to control the lives of the citizens. These control mechanisms can be seen as both freedom-reducing and freedom inducing depending on which concept of freedom one upholds.

This thesis evaluates the environmental performance of six different fish farming systems. The thesis is part of the network group ?Hållbar fiskförsörjning I Stockholms län? (HFFS) which tries to increase the domestic and regional production of fish in Stockholm and move to a more sustainable supply in the Stockholm county. Two of the chosen systems; pangasius from Vietnam and salmon from Norway are delivering a substantial part of the fish consumed in Stockholm today, although they are very different when it comes to system characteristics. One system, arctic char with conventional feed, is produced in a fairly small scale in the north of Sweden, while the three remaining systems are viewed upon as possible options to supply Stockholm with fish in the future.

Syftet med föreliggande undersökning är att få kunskap om hur några arbetslösa ungdomar upplever sin situation som arbetslös, vilket studeras med fokus på framtidstro, sin egen förmåga/kompetens till att påverka möjligheterna att få jobb samt vilka faktorer de upplever är viktiga när det gäller att få ett jobb inom en snar framtid. Detta studeras utifrån teorierna om locus of control och self-efficacy. Två tjejer och fem killar i åldrarna 16-24 år, samtliga arbetslösa och inskrivna på Ungdomskraft, deltog i semistrukturerade intervjuer. Resultatet visade att majoriteten av ungdomarna har en hög tilltro till sina egna resurser och upplever att de själva har kontroll över sin situation som arbetslös. Vidare visade resultaten på ett mönster mellan intern locus of control och hög self-efficacy i samband med en positiv framtidstro med avseende på att få ett jobb..

The background to this final thesis is that our mandator, A-hus, was interested to examine which roof system that would be most appropriate to their types of houses. To investigate this, we first conducted an evaluation of the most commonly used roof systems in Sweden today: decking, board, roof cloth and prefabricated roof cassettes.To gather information about the different systems we have conducted interviews with several professionals within the construction industry, done an extensive literature study, and gathered information from the Internet.Based on the evaluation of roof systems and the literature, we analyzed advantages and disadvantages of the roof systems from three main perspectives: system characteristics, economics and other characteristics. We found these perspectives to be the most relevant when selecting a roof system.The main perspectives comprise three categories which are graded. These grades are then added together for a score for each main perspective and a total score for the three main perspectives. Then we compared the systems and, based on the scores, suggested one roof system as the most suitable for A-hus.Our result suggests that the prefabricated roof cassettes probably is the best solution for A-hus, but only if it is possible to standardize the cassettes and still maintain the flexibility to match A-hus? house types.

Learning Management Systems (LMSs) hold great potential to support learning activities, for example by providing teachers and students with new and extended spaces for interaction and collaboration. However, this potential appears to be difficult to realize, and despite their perceived learning benefits, the reality is that LMSs are being used primarily for administrative purposes. Meanwhile, external pedagogical tools are successfully put into practice to improve learning outcomes, and the aim of this study is therefore to identify and discuss benefits and disadvantages associated with the LMS as a concept. By interviewing secondary school teachers, we disentangle the idea of integrating administrative and pedagogical aids into a single platform, providing detailed insight into the use of digital tools in secondary education. The study contributes to a deepened understanding of integrated learning environments, and we conclude that there is a conflict between structure and flexibility that needs to be addressed before determining the design of a digital learning space..

The aim of the study is to get a better understanding of leader's reactions in a crisis situation, and to examine whether locus of control and coping strategies can be related to leaders need for social support. The role of a leader in a crisis situation is complex and includes several aspects which must be illustrated to understand the leader's situation. Four leaders have participated in the study. The methods that have been used are questionnaires for measuring locus of control and coping and semi-structured interviews. The results show that search for social support cannot be seen as an outcome of a specific locus of control or coping strategy.

The world is currently facing a huge severe challenge in handling the issue of climate change. One of the ways to lower the green house gas emissions, which is seen as one of the main contributor to the climate crisis, is to use renewable technologies such as for example photovoltaic (PV) systems. PV-systems are also suitable for so called micro production, small scale energy production facilities, since it can be placed on practically any rooftop with the right solar conditions. In Sweden the usage of PV-systems has not yet gotten any wider spreading, even though the solar radiation conditions are very similar to countries that produce a lot of solar energy, as for example Germany. The aim of this paper is to describe non-adopter perceptions of PV-systems. The study holds a qualitative approach using deep interviews for data collection.
