Vetenskaplig publicering i gungning

Scholarly publishing has since the introduction of electronically distributed periodicals seen a time of change, mainly in the STM-business (Science Technology and Medicine). The roles of the three main participants in the publication process; researcher, publisher and library are developing into new directions. Researchers themselves are taking a more active part in the discussion, with the boycott list from the Public Library of Science organization as an illustrating example. Reforms are being launched partly as an economical and efficiency issue, partly as an increasing desire from researchers to maintain the control of scientific end result. This Master s thesis examines how the partly conflicting goals of the participants affect the conditions for scholarly publication in an electronic environment.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Trans fatty acids from ruminants - and its effect on blood lipidprofile in healthy men and womenAuthor: Sophie Berg and Sara KarlssonSupervisor: Henriette PhilipsonExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2012BackgroundCardiovascular disease is the most common cause of death in Sweden. It is well known that thereis a link between high consumption of industrial trans fatty acids and cardiovascular disease, buthow natural trans fatty acids affect us remains uncertain.ObjectiveThe purpose of this article is to, based on the currently available scientific evidence, concludewhether an intake of trans fatty acids from ruminants generates an effect on the bloodlipid profile of healthy men and women.Search strategyRCT articles were obtained through searches in databases such as PubMed, The CochraneLibrary, and Scopus. Keywords used were "ruminants" AND "Cholesterol" AND "Trans FattyAcids" and "ruminants" AND "Blood Lipids" AND "Trans Fatty Acids".Selection criteriaInclusion criteria were RCT studies conducted on healthy people who did not receive medicationfor hyperlipidemia. Moreover, the results were to be based on fasting blood samples, where atleast ten hours of fasting preceded the analysis of the blood lipids.Data collection and analysisThe search generated eight studies. These were graded according to SBU:s Granskningsmall förrandomiserad kontrollerad prövning, after which four studies were selected.

Utvärdering av avloppsvattenreningen vid Hallsta Pappersbruk : Kartläggning av inkommande avloppsvatten och optimering av driftparametrar

Hallsta paper mill uses large amounts of water during the pulp and paper making processes. The wastewater is treated in two separate activated sludge processes referred to as BIO 1 and BIO 2. The main aim is to reduce the organic substance content, measured as COD (Chemical Oxygen Demand) before the wastewater is released into the environment. Since the effluent produced is very rich in organic substances, the addition of nitrogen (N) and phosphorus (P) are necessary to give satisfactory treatment results. Problems with sludge bulking sometimes occur which lead to increased levels of suspended matter and nutrients in the effluent.

Förskollärares kunskap om stress och stresshantering bland barnen på förskolan

This work examines the students´ thoughts on climate change with a focus on carbondioxid through photosynthesis and the carbon emissions from cars. The study is based on two subject areas, one with a focus on enhanced greenhouse effect, and the other focusing on photosythesis. The survey was conducted by means of qualitative interviews with students in grades four and six. The results describe that student´s understanding for photosynthesis and the carbondioxids function for photosynthesis doesn´t change significantly from grade four to grade six. I have divided the students inte three levels based on their understandingof the various fields, and their use of adequate concepts.

Framtidens gymnasieskola - En styrning utifrån ett modernistiskt eller senmodernistiskt perspektiv?

This empirical work and base has been to analyze the new high school reform that the Swedish government introduced as a statement 2008/09:199 about: Higher demand and quality within the high school. This statement became legal through the government vote in spring 2010. But above all it is the investigation (SOU 2008:27) that is the central piece for these new examination changes for high school students that will come into effect 1 of July 2011. The purpose and questions asked in this analyze has been if the reform takes its base in a modernistic (traditional) way or a late modern scientific perspective. And also to find out how these new quality amendments in the investigation makes visible about the high school and what the purpose are about the changes. When scientific theories in these analyze is placed against the reform, the result shows that the modernization process reflects more of a late modern aspect, which constantly reappraise in a changeable society.

Quadrotor UAV : Konstruktion och användbarhetsstudie av en UAV i sensornätverk

Quadrotor UAVs are self-stabilizing, autonomous flying machines that has recently become more popular than ever. Unmanned Aerial Vehicles have their roots in the military, where they were developed for use in reconnaissance and combat. During the last few years, advances in the fields of electronic sensors, electric motors and microcontrollers have enabled smaller designs and autonomic flight control even for private use. The quadrotor, which is the particular kind of UAV we are looking closer at in this paper, has 4 rotors in an X-like formation. This configuration has many advantages such as good lift capacity, non-complex mechanical structure and serviceability.In this project we aquired a current overview of the domain and determine whether it is possible to construct a quadrotor UAV designed for use in a WISENET sensor network on a low budget and short time schedule.Based on existing community project AeroQuad, a quadrotor is constructed with a budget of about 500 euro.

Medling vid brott : En explorativ studie av medlingsprocessen på Höglandet

Mediation is a process in which various actors are involved with each other, this involvement is what the mediation are built on, because all the actors complement each other, they coordinate their work. This is not an interaction between various actors, it?s a participation. There is no research on this kind of participation, and therefore we believe that this is a scientific problem. The purpose of this paper is to implement an exploratory study of stakeholders views on the mediation process.

Kommentera här! : En kvalitativ studie om nyhetssajters kommentarsfunktioner

Studien tar avstamp i den diskussion som förts kring nyhetssajternas kommentarsfält. Diskussionen kulminerade under sommaren 2011 då flera nyhetssajter ändrade sina förhållningsregler och vissa fall även de tekniska lösningar som användes. Denna studie ämnade undersöka om valet av kommentars-teknik påverkar användares vilja till kommunikation på nyhetssajter, men även att belysa eventuella bakomliggande faktorer till detta. Detta har genomförts genom en kvalitativ observations- och intervju-studie. Resultatetav studien påvisar att kommunikationen påverkas av valet av teknisk lösning, och att bristen av kontroll är en av de avgörande faktorerna bakom huruvida en användare är villig att kommentera en artikel..

En lycklig omställning av Sverige

This paper aims to examine how and to what extent, a transition of Sweden according to the principles of Omställning Sverige (Transition towns Sweden), have the potential to contribute to a society with increased happiness.The paper is based on a qualitative textual analysis of the key texts in the Swedish Transition towns movement, Omställning Sverige. In the first part of the study the most important transition principles of Omställning Sverige were identified. Four key principles emerged: An altered view of economics, a spiritual change, a stronger local community and increased awareness. These transition principles were then analyzed through the lens of the Scientific fields position on happiness, followed by a summarizing conclusion.The altered view of economics which Omställning Sverige advocates, where sustainability and quality of life are priorities over economic growth, is even necessary to secure our basic physiological needs. Such an economy has also improved conditions for economic stability, high employment and higher efficiency in the sense of happiness promoted in relationship to how many natural resources are used.
