Frihet från ansvar : Professionellas kunskaper om sexuella riskbeteenden vid HIV-infektion utomlands
Theories about exposure and risk-taking in an everyday environment show a connection between parental strategies, parent-child relationship and exposure on the Internet. In the present study, the Internet is presented as an everyday activity. Negative exposure is seen as an outcome of risk-taking. The purpose of the study was to examine in what way parental strategies together with the parent-child relationship were related to the teenagers? negative experiences on the Internet, which consisted of three categories: 1) Exposure to pornographic sites, 2) Exposure to upsetting and violent material, 3) Digital bullying.
Bilden av Sverige i morgondagens EU : offentlig diplomati i en föränderlig värld
Purpose/Aim: The purpose of this paper is to describe how a number of strategically selected employees at the Swedish Institute, with the purpose to promote Sweden in the world, look at the challenges facing Sweden concerning nation branding in the new era of cooperation within the European Union. I examine how these people look upon the work of public diplomacy and nation branding in order to actively participate and influence the EU's common communications platform.Material/Method: The method used in this thesis is qualitative interviews. The reason why I chose this method is because I consider it to be the most appropriate in order to collect information about how these selected employees at the Swedish institute regard the challenges that lay ahead in terms of nation branding within the European Union.Main results: On the basis of the results I have gained by dint of the analysis, it can be concluded that it is of utmost importance to take the societal changes, which are a result both of the worldwide globalization and the EU cooperation, into consideration when designing a future communication strategy for the Swedish Institute. The nation-state continues to play an important role in Sweden, but its importance is declining as the EU cooperation is progressing. The citizens? identity plays a crucial role in designing a nation?s communications strategy, and from the analysis I conclude that we move not from a Swedish to a European identity, but towards a pluralistic union where multiple identities meet under one umbrella; the EU..
The effects of Joint Ventures announcements on stock returns behaviour - An Event Study of the Stock Market
The purpose of this study is to examine the effects of joint venture announcements on stock prices behavior and simultaneously to test the German stock market (Frankfurter Wertpapierbörse) for efficiency. We tried not only to analyze the general impacts of a JV-announcement but also to look for differences in the market response to announcements of different types of joint ventures, namely: domestic, international, horizontal and vertical. Our expectations of efficient market were confirmed during our paper, which employed the technique of the standard event study. The calculation of abnormal returns which are the signals for market efficiency or inefficiency respectively were based on the market model, establishing linear relationship between the return on the market and the return on an individual security. The parameters of the model were obtained through regression analysis..
Sierra Leone och Botswana : Hur kan ett land nå demokrati och ekonomisk tillväxt?
AbstractSierra Leone is a very poor country in Africa. Botswana is another country, that has a similar history and the same deposit; diamonds. Botswana has reached economic growth and democracy and Sierra Leone has not.The purpose with this study is to explain why Botswana is more democratic and has reached a better result economic than Sierra Leone.The questions in this study are:What explains the democratic and the economic results in Sierra Leone and Botswana?* Dahl?s institutions that furthers a polyarchy?* Gunnarsson?s and Rojas? institutional explanations?* Diamond?s and Morlino?s ?rule of law??* Other explanations or a combination of the above-mentioned explanations?The method that has been used in this study is a comparative case study with a qualitative contents analysis. The result is that it?s hard to say that one explanation is the right one.
Länkanalys: En undersökning av ett biblioteks- och informationsvetenskapligt delfält
The aim of this study is to analyse and investigate a rather new field of LIS studies, i.e. link analysis which is a part of webometrics. Webometrics has been described as the quantitative study of web based phenomena drawing on bibliometric or informetric methods. Link analysis has its counterpart in citation analysis within the field of bibliometrics. The questions the study investigates are if webometrics can provide LIS with new knowledge and if there is a place for webometric studies in LIS research.
Genom statistisk analys utvärdera geometriska parametrars påverkan på ett XPI- cylinderhuvuds snurrtal
This Master Thesis is a product development project that has been carried out in cooperation with Scania CV AB. The purpose has been to find the relationship between geometric parameters and the swirl number for an XPI- cylinder head in order to improve the design specification.The increased focus on environmental issues from society leads to tighter emission legislations for the truck manufactures. In order to drive the development forward considerable resources are spent on research and development on diesel engines and its combustion process. The inlet air has a significant impact on the formation of emissions and the flow that is desired is called swirl. Swirl is achieved by making the air rotate around the vertical axis of the cylinder.Earlier cylinder heads that has been developed at Scania CV AB have shown clear relationships between geometric parameters of the cylinder head and the swirl number.

Alpin permafrost i Kebnekaisefjällen : Modellering med logistisk regression och BTS-data
Denna studie är ett försök att modellera den alpina permafrostens utbredning inom Kebnekaisemassivet i norra Lappland. En karta som visar sannolikheten för permafrostens utbredning har skapats med hjälp av data från Bottom Temperature of Snow cover (BTS) - mätningar samt statistisk modellering genom logistisk regression.Fältstudien genomfördes under mars till april 2011 med totalt 56 BTS-punkter från 1073 till 1805 m.ö.h. Permafrostförekomsten bestämdes vara en funktion av höjden. För att utreda detta användes stepwise selection som är en metod för att identifiera statistiskt signifikanta variabler gentemot en beroende variabel. De andra parametrarna som testades var topografins sluttningsgradient, riktningen av den maximala lutningen och den potentiella solinstrålningen.
Barkar det åt skogen för svenskt tidningspapper? : empirisk analys av efterfrågan och företagsstrategier på den svenska marknaden
According to Food and Agriculture Organization newsprint is defined as: Uncoated paper, unsized (or only slightly sized), containing at least 60 percent of mechanical wood pulp. The consumption of newsprint in Sweden was just over 798 000 tonnes in 2009, which represents approximately 90 kg per person. Although there are studies that predict a drastic reduction in newsprint consumption in the Western world, there seems to be a clear difference between forecasts for the future given by statistical analysis of newsprint consumption and forecasts given by experts in the industry. The former predict a continuing increase while the experts see a coming decrease in consumption.In this report, both demand and business strategies of newsprint in Sweden are studied. The study also presents a forecast of the future which is based on historical data and qualitative interviews.
Ärade Statsminister 2,0 : Breven till statsministern om den ekonomiska politiken
Vilka ekonomiska frågor ligger närmast de svenska brevskrivarnas hjärtan? Två svenska professorer, Becker och Jonung undersökte detta 1998. Denna studie undersöker i ett världsunikt data set innehållande 536 brev adresserade till statsminister Fredrik Reinfeldt under hans mandatperiod 2006-2014. Genom undersökningen ges en övergripande bild av brevskrivarnas mest centrala frågor rörande ekonomi. Utgångspunkten ligger i att undersöka skillnader i fördelningen av brev mellan denna och tidigare studie.
Ekonomisk policy och tillväxt i en transitionskontext: en studie av realsocialistiska länder
Abstract During the last 15 years, the former ?really existing socialist? economies have undertaken an extensive transition process. In this paper the development, measured as GDP growth, is analyzed using variables for economic policy. The analysis is both theoretical, taking as starting point current positions in academia, and econometrical with the linear regression model. We show that while economic policy variables of inflation, economic freedom and institutional quality affect economic growth, the results are not only the ones predicted by the theory.

Samband mellan en längre tillväxtsäsong och en ökad smoltstorlek i Vänerområdet
AbstractThe purpose of this study was to see if there is a connection between smolt length from Brattfors salmon cultivation and temperature. Climate changes are expected to give a higher temperature that could result in a longer growing season for the fish.Cultivated smolt is today bigger than it was before, it is also bigger than the wild salmon. The growth season of salmonids depend on the water temperature, salmonids need 6-80C to grow. Water temperature has been surveyd since the late 50´s in Brattfors. The result shows that it?s now considerable more days per year with higher temperature.
Ett varumärke för varje behov: Balansering och differentiering av varumärken i multi-brand portföljer
Multi-brand portfolios are characterized by comprising many brands in the same product category. Companies that have chosen to organize their products according to this strategy are facing both possibilities, such as expanding the accessible market size, and challenges such as how to organize the brands, their individual roles and their relation and position to the other brands in the category to maximize revenues. To address these aspects of multi-brand portfolios, I have investigated four product categories where multiple brands are represented at Mölnlycke Health Care, Unilever, Fagerhult and L?Oréal; how the multi-brand portfolios are organized, how the segmentation, positioning and product differentiation are done and what advantages and disadvantages that are associated with this strategy. My conclusions are that multi-brand portfolios can be organized in many different ways and to become successful, they have to be set in relation to the company?s whole brand architecture.
Genetisk studie av inavel och fertilitet hos hund :
Inbreeding, the mating of related individuals, has been the one dominating breeding strategy for dog breeders during the last 200 years. However, its negative effects on fer-tility and other fitness traits, a phenomenon called inbreeding depression, have been ignored in the quest of perfect unity in conformation or performance. The purpose of this study was to test the hypotheses that litter size is reduced as a consequence of in-breeding, affected by both the inbreeding coefficient of the dam and the litter and that a rapid increase in the inbreeding coefficient affects litter size more than a slower rate.
Data were collected from the Swedish Kennel Club registry of origin. Breeds included in the study were the Bernese Mountain Dog, the Cocker Spaniel, the Golden Retriever, the Rottweiler and the West Highland White Terrier.
