There are five endemic populations of migratory Atlantic salmon (Salmo salar, Salmonidae) and brown trout (Salmo trutta, Salmonidae) remaining in Lake Vänern, whereof two are salmon and three are trout. There is one population of each species in Klarälven, also one of each in Gullspångsälven and there is a population of trout still remaining in Tidan River. Since the beginning of the 20th century endemic populations of salmon and trout have either vanished or declined dramatically due to the construction of hydropower in the rivers around the lake, and still today the future of the remaining populations remains uncertain. To manage salmonid fishes effectively more knowledge of their ecology throughout their different life-stages is needed. A large part of the Lake Vänern salmonoids lives are spent in the lake, where a mayor mortality factor is recreational fishing, especially angling.

Occupational stress and the use of alcohol to reduce stress are both separately common in our society. A few researchers have combined the two factors.The aim of this essay was to obtain an increased understanding of how male and female managers estimate their alcohol habits in relation to their occupational stress.We have interviewed nine managers who work at a social services department in Scania. Our main theories were the theory of psychosocial work environment of Lazarus, Karaseks demand/control model, epidemiology- and cultural perspective.Our results were;· Psychosocial work environment contributes to if the interviewed people experienced stress at work.· The grade of control has great influence if the interviewed people experience stress.· There weren't any correlation between stress and increased consumption of alcohol..

Enterprise learning is a pedagogic concept that implies that the students, in correlation with development of theoretical, subject specific knowledge, also develops enterprise competences that will be useful in their everyday life and on the labour market. Enterprise learning has grown over the last ten years, as well in school practicing as within research. In the mathematics subject, a strong educational tradition has delayed the introduction of enterprise learning. At the examined school, enterprise mathematics has been introduced during the spring term of 2010. This examination focuses on which of the enterprise competences that are developed and how they are developed.

Purpose: The study examines the risk a rising from the acquisition of shares, and its relation to the expected return. We would like to see how a high-risk portfolio is related to a low-risk portfolio. Although studying the portfolios annual performance.Theory: The theories that have been used in the study are, Capital asset pricing model, CAPM and portfolio theory.Method: The study is based on a quantitative method, the time interval is from 2008 to 2010.The annual reports, historical stock prices for companies and the index are used to perform calculations based on the essay theories.Conclusion: The beta value has positive liner correlation with the expected return. When there are bad times in the world, the companies are negatively affected regardless of industry. The Portfolios developed in the same direction during the time period..

The purpose with this study is to examine how the twelve-step program is described by the author J Keith Miller (2004) in his book Steg in i livet and by the author Olle Carlsson (2012) in his book 12steg för hopplösa. The aim for the study is to highlight the twelve steps usage on people without addiction problems. In the study, the two author?s thoughts and experience of the twelve-step program is analysed and interpreted by Pargaments (1997) theory of religious coping. The research questions in this study are: 1.

Background: Testosterone is the most important androgenic hormone in the male. Aging is closely associated with reduction of serum testosterone which can lead to reduced muscle mass, muscle strength, bone density, and depression. These symptoms may be counteracted by administration of testosterone. Objective: The purpose of this study was to examine the effects of hormone replacement in men with age-related testosterone deficiency. Method: We performed a systematic review using Randomised Controlled Trials (RCT).

The main purpose of the present study was to collect Swedishnorm data for the comprehension scale of the Reynell DevelopmentalLanguage Scales (RDLS III) for the ages of 4:6-4:11. According to theBritish manual the degree of difficulty increases gradually and therefore theorder of the sections was examined to see whether this was the case inSwedish. The study also examined the relationship between the test resultsand shared book reading. A total of 88 children and their caregiversparticipated in the study. The participants were recruited from preschools inGöteborg and Mölndal.

The purpose with my essay was to investigate how genre pedagogy works in a practical manor? I wanted to reach a deeper understanding for the genre pedagogy and to find out if it fits all students. To investigate this issue I have asked following questions:What is genre pedagogy?How do teachers work with different genres in the genre pedagogy?For whom is the genre pedagogy?Is the critic right that Frøydis Hertzberg is proposing about the genre pedagogy formalism? I have been using qualitative methods, to gather my empirical data. I have been using two unstructured interviews and one unsystematically observation, in a third grade class in a school south of Stockholm, with 30% second language students.

The market for eco-labelled products has developed rapidly from the early nineties in Sweden. There is a full variety of environmentally friendly products on the market today, and perhaps organic food is the most popular alternative. Eco-clothes have not reached the same amount of success as other eco-labelled products on the Swedish market. In this essay I will discuss and analyze which factors that have influenced green consumers attitude and behavior towards eco clothing. Four interviews with green consumers in Karlstad have been done in order to explore consumers attitude and behavior.

This paper is a study how students at a high school in Falun, Sweden, estimates theirperformance in an upcoming math test which is then compared with the actual grade thestudent performed. The students who participated also answered questions related to ?risksituations? to examine whether there is a correlation between how students estimate theirperformance in the context and their risk behavior, and if the students act like economicmodels assume. In agreement with previous studies, the boys in the survey tended to beoverconfident in their performance. The girls in the study were neither over- norunderconfident in her performance and no significant difference in the estimation of one'sperformance between the sexes could be proven.

The effect of methyl jasmonate on resistance against the large pine weevil (Hylobius abietis) in Scots pine and Norway spruce seedlings. A field experiment was conducted in order to determine the dose-response effects of methyl jasmonate (MJ) on growth and defence to pine weevils in Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) and to compare the effect of MJ between pine and spruce. In addition a complementary greenhouse experiment was conducted with the same aims as above and to determine the amount of resin ducts and their correlation to the feeding of pine weevils. The field experiment was conducted on a fresh clear cutting in Garpenberg, southern Dalarna in central Sweden. The experiment consisted of 30 blocks with three kinds of containerized seedlings: 2-year old spruce, small pine (before shoot elongation) and 1-year old pine (already shoot elongated). They were all exposed to 4 treatments 14 days prior to the experiment: control, 25 mM/L MJ, 50 mM/L MJ and 100 mM/L MJ. Data on weevil damage and seedling growth were collected after the first and the second growing season. The seedlings in the greenhouse experiment were of the same kind and were exposed to the same treatment as the ones in the field experiment.

The Swedish system of environmental quality objectives is a so-called MBO, Management By Objective and has the purpose to guide the Swedish society towards sustainable ecological development. The system involves the whole society from the parliament and the government down to individual citizens. At the regional level, it is the county administrative boards that are responsible for the work with the system of environmental objectives. At the County Administrative Board of Västmanland County, it is the environmental unit who is in charge of work with the environmental objectives and they want input for how to improve their work with the environmental objectives, both internally at the Administrative Board and externally with external parties.The main purpose and goal of the study is to present the work of four other county administrative boards regarding their work with the environmental quality objectives and to identify external parties? opinions of how they want the County Board of Västmanland county to work with them in this matter.The work is designed as a case study of four county councils, where the environmental objectives coordinators at the four county administrative boards were interviewed about their work with environmental quality objectives.

The aim of this study was to examine nurses knowledge and attitude towards HIV/AIDS patients over the world. A descriptive literature study has been made based on scientific articles from the databases PubMed and Cinahl. The authors have examined the sampling and the falling off of the articles. The result shows that the attitude towards HIV patients is different from one country to another. The attitude was affected by several of factors such as experience, fear, knowledge / education and the nurses attitude and willingness to care for these patients.

This study is an institutional analysis of the firm both as it is theoretically conceptualized and how it takes shape and changes. The role of power relations between manage¬ment and employees is especially examined with the aim of evaluating pos¬sible connections between the firm as an institution and power relations within it. Based on a comparison of two cases (two selected periods of the same organization) it asks ?How closely does each case match the conceptual characteristics of the firm??; ?What are the power relations between management and employees in each case??; and finally ?What factors account for the resulting differences??. It is found that there is a negative correlation between employee power and proximity to the firm as a concept.
