The study aims to investigate the feasibility of small-scale electricity production with solar electricity systems, also known as PV (photovoltaic) systems, in Australia. Due to the global warming, sustainable energy has in recent years become an increasingly important issue, both internationally and in Australia. With one of the largest dependencies on fossil energy sources in the world, the country's abundant solar radiation is a possible solution to this issue.Both the technical and the economic feasibility of small-scale PV systems were investigated. On the technological side, the electricity generation, distribution and consumption systems were studied. On the economical side, the parameters that drive the profitability of a PV investment were investigated.

Bröstcancer är en sjukdom som ofta bringar lidande och är viktig att förebygga. Utövande av fysisk aktivitet har i tidigare studier visat sig ge en minskad risk för att få bröstcancer. Litteraturstudiens syfte var att skapa en översikt över sambandet mellan fysisk aktivitet och bröstcancer hos kvinnor. Sökning, urval och granskning av artiklar har utförts. Resultatet visade att fysisk aktivitet hade ett starkt samband med minskad risk för att få bröstcancer för både pre- och postmenopausala kvinnor.

This paper is finishing part of the two-year master programme in Industrial Engineering and Management.Initially there was an inquiry of studying the queue-times that Fläkt Woods uses when they break down internal working orders. These times were assumed to be too generalised and does not apply to the actual value of the queue-times which generates incorrect data and delivery delays. During the work of this paper it has been established that it is not the queue-times that is the biggest problem. The problem is the shop floor control and the lack of manufacturing the right products at the right time. Therefore an analysis of the production planning process was made to bring forward the real problems.

Pressure ulcers cause a lot of patients unnecessary suffering. This suffering could be decreased through improved knowledge about prevention, so that pressure ulcer will not appear. The purpose with this review was to study how nurses assess risk and prevent pressure ulcer, and to study how nurses use available knowledge. The method consisted of searches in databases and searching trough references. Our result is based on ten articles, qualitative, quantitative and reviews.

Musculoskeletal disorders (MSD) are common in individuals with computer based work. Thecurrently known risk factors for these disorders is in the literature derived to physical,organizational and individual factors. A recent survey of three working groups at a companyin Stockholm explored that more than 50% of the employees had neck and shoulder problems.Aim: The study aims to create a better understanding for the current musculoskeletalproblems at the company. Such an understanding is created by examining the physical,organizational and individual risk factors in the workplace and the result can provide a goodbasis for intervention proposals.Method: In order to answer the aim of the study the authors chosed to use both qualitativeand quantitative methods of data collection through interviews and questionnaire survey. Theinterview and questionnaire was designed to create both a specific and comprehensive pictureof the physical, organizational and individual risk factors having a bearing effect on theexisting MSD problem.Result: Seven categories were compiled from interviews, which largely deals with the factthat high demands can lead to behaviors that may pose a significant risk for the occurrence ofMSD.

Obesity is a growing problem worldwide among children and adolescents. Previous research has shown that food habits and weight in order children with high and low risk of developing obesity (based on parental BMI) differs between the two groups.

The purpose of this thesis is to gain understanding of how companies proactively can manage their reputation. The thesis analyzes three multinational companies in Sweden and uses two theoretical approaches - the reputation risk view and the reputation strengthening view - to gain an overall perspective of how companies work with their reputation. It focuses on investigating which key areas of reputation risk the focal companies identify and how they manage the reputation risks within these areas. Moreover, it examines which stakeholders the companies believe are most critical from a reputation point of view and in what ways the companies work with strengthening their reputation among those stakeholders. In order to find a general approach, the thesis investigates the similarities and differences that exist between the respective companies in the study.

Our purposes with this essay was to increase our knowledge about, and try to describe, how it happens when people get involved in gambling and becomes addictive to gambling, and what the way out of a gambling addiction could look like. Our framing of the question was: - How does gambling begin? - How does gambling evolve to an addiction and how does it go forward from there? - How do you leave a gambling addiction? Is there an experience of turning points? We did qualitative interviews with six former gamblers. Our main conclusions were that the initiation to gambling can be very different and still lead to similar effects. There seems to be a strong enticement surrounding the attributes of gambling, which are connected to developing a gambling addiction. The experiences of turning points were very palpable.

The purpose of the thesis has been to explore the use of hedge fund styles when constructing portfolios of hedge funds (i.e. funds of hedge funds). The central question is if the use of hedge fund styles can significantly explain and improve risk adjusted returns (characterized by Sharpe ratios). The study has been done in collaboration with Optimized Portfolio Management AB who desire further knowledge and evaluation of hedge fund styles for their fund of hedge funds.To be able to create successful ex ante portfolios we have explored various prediction models for both risk and return. Our findings indicate that return prediction is problematic using simple models such as regression since the risk exposure of the indices appear to change significantly over time.

SyfteSyftet med studien har varit att ta reda på hur ungdomars drogvanor när det gällercannabisanvändning ser ut, och ställa detta mot risk- och skyddsfaktorer som kan finnas i skolmiljön samt inom familjen för att utröna om det finns några samband mellan cannabisanvändning och ovan nämnda faktorer. Frågeställningarna är: Hur ser cannabis- användandet ut i förhållande till kön, årskurs och stadsdelsområde i Göteborg år 2010?

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..

This paper deals with the question of neolithisation of Southern Scandinavia. The main goal is to give an overview of three theories regarding how agriculture and livestock breeding was introduced to the Southern Scandinavia. These are as follows: the immigration theory, the socio-economic theory and the historical explanation theory. Furthermore it is investigated which theory has the most probably support in material culture. There are obvious difficulties in interpreting the archaeological material.

The content of this essay is the critical treatment of ritual research in Uppåkra during the Iron Age in relation to Charlotte Fabechs research.From what has been concluded for Uppåkra a condensed chart of Uppåkra's rituals is produced. This chart is compared with what Fabech has put forward for Southern Scandinavia. Fabech's categories and theory have been widely used by the researchers of Uppåkra, and this is critically examined.The most important conclusion is that the similarities between the Uppåkra research and Fabech picture are not great. This source critical point indicates that the massive use of her research in order to explain the rituals in Uppåkra can have been misdirected. The mismatch is mainly due to the fact that places like Uppåkra is of extraordinary character..
