Ever since it was first introduced in an article in the Journal of Finance 1952, Harry Markowitz? mean - variance model for portfolio selection has become one of the best known models in finance. The model was one of the first in the world to deal with portfolio optimization mathematically and have directly or indirectly inspired the rest of the world to develop new portfolio optimization methods. Although the model is one of the greatest contributions to modern portfolio theory, critics claim that it may have practical difficulties. Partly because the Markowitz model is based on various assumptions which do not necessarily coincide with the reality.

The development of higher education in Sweden poses new demands on higher education libraries. One way of meeting these demands has been to develop Learning Resource Centres (LRC), a concept that is relatively new in Sweden.The aim of this Master's thesis is to identify how the LRC-concept has been designed and integrated in three Swedish higher education institutions: Stockholms universitet, Lärarhögskolan i Stockholm and Göteborgs universitet. The thesis also aims at investigating what the Learning Resource Centres mean to the seats of learning, and in turn, the views of concerned parties in relation to the integration.The method used for the study is qualitative and based on interviews conducted with Learning Resource Centre staff, academic staff and principles or deans. In addition to this, strategic documents from the examined seats of learning are studied.Even though most Swedish Learning Resource Centres have used British Sheffield Hallam University's Adsetts Centre as their model, our study shows that the Swedish Learning Resource Centres of today have developed in various ways, due to local conditions; therefore, there is no definitive model for Swedish LRCs.In our opinion, one of the most important characteristics of a LRC should be its integration in the academic life of its university. There does not seem to be a "recipe" of how to conduct this integration.

Sweden is usually seen as a role model when it comes to integration and diversity, but at the top of the pyramid there is little ethnical diversity to be found. This paper investigates how existing economical and sociological theory explain the lack of swedes with foreign background in leading positions in large Swedish companies. Our findings show that none of the theories applied in this paper can explain the phenomenon in isolation. Thus it is not only taken for granted norms, contacts in one's network or cost minimizing under asymmetric information that lie behind the phenomenon, but an interaction of these aspects. Conflicting demands lead the recruiters to separate talk from decision, the search frame is narrow and no or small efforts are made to increase the diversity.

The purpose of this essay is to state a fundamental model which can describe the sounds of the city, emphasizing on its rhythm. The essay is based on a theoretical study that deals with essential elements to describe a soundscape. The theories presented are founded on R. Murray Schafer's theses about soundscapes, Bert De Coensels theses about rhythmical sound patterns and Ambjörn Hugardts view on rhythm. The model that is presented stresses the importance of a multidisciplinary perspective when one attempts to understand and describe a soundscape.

Background: Every year 56 million people die around the world and it is estimated that 60% of these people are in need of palliative care. It has been shown that patients in the palliative care experienced their situation as uncertain. When life no longer was certain, the patients tried to live their life day by day and make the best of it. Problem: When patients were diagnosed with an incurable disease the future became unsure, because their life would come to an end. Therefore patients with a palliative diagnosis could be in need of experiencing feelings of security.

When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.

Background: outsourcing is one of the most obvious and continuous trends that has been able to study during the past ten years and also has had a strong development in the industry. What consequences will follow from an extended outsourcing? Purpose: the study?s overall purpose is to investigate what possibilities and risks that can be connected to an outsourcing decision and how the order of the service will handle the risks. The study will also investigate what management philosophy that will be used and regulate the outsourcing relation and how the company?s strategy will affect the decision and how the process of outsourcing will look like.

The purpose of this study was to increase the knowledge and understanding of what impact support-groups, such as represented by Qvinnoqulan, can have on women with drug-addiction. The questions at issue for the essay was: How does a selection of women who participate in Qvinnoqulan describe their thoughts, experiences and reflections of the group? What sense has Qvinnoqulan made for the women on a personal level and for contributing to live a life without drugs? To answer the questions a qualitative method was used and five interviews were made with women who participated in the activities of Qvinnoqulan. To analyze the data a social constructionist perspective and an empowerment perspective was used. The result of the study showed that the women were in the process of rebuilding a new life without drugs and reconstructing a new identity.

The aim was to describe the experiences of couples where the male partner had undergone radical prostatectomy due to prostate cancer. Furthermore, the study explored how the operation had affected their sexual life, whether the couples had received enough post surgical support and information concerning these issues, and to describe the kind of support and information these couples desired. Twenty men and ten partners participated. All the men experienced a varying degree of post surgical erectile dysfunction and only five men had received support concerning their sexual life. Eleven men desired professional visiting support activities.

In today's society, the internet is an important part of everyday life. Over recent years the number of electronic services has increased markedly. Communities such as Facebook, consume more of people's time than 5-10 years ago. How can public authorities benefit from these communities or are the municipalities not ready for this? The municipalities determine how their resources should be allocated based on the municipality's needs.

The aim of this study was to examine if performance-based self-esteem, personality (Type A), perceived stress, age and gender predict the value of own or others life-stress (VLS). The aim was also to examine whether the variables were correlated significantly with each other. The investigation was conducted in a town in the mid-south of Sweden. The instrument consisted of two forms where the first measured Type A personality and the second tapped perform-ance-based self-esteem, perceived stress and the level of life-stress. The results showed that the level of life-stress could explain, on the basis of the predictors, performance-based self-esteem, personality (Type A), perceived stress, age and gender.

I have done a case-study about building a new stable for slaughter pigs at a farm close to Kalmar. The farm is able to supply the breeding with cereals and it has enough area to spread the manure on. The most important factors to gain profit, is the cost for building the stable, the price of the feeding-stuff and the growth of the pigs. The discount from the slaughter-house was less important than I thought from the beginning, and it?s a factor that is hard to influence. With the new production of slaughter-pig and cattle that already exist on the farm, the farm will get a well-functioned rotation of crops with lye and autumn rape as interruption-crop.

The aim of our thesis was to gain greater knowledge of how young people relate to religion, religiosity and life, and this behavior might show influences of a gender perspective. Part of the aim was also to have greater awareness of how our education should include a gender perspective. To get to this goal, we have assumed the qualitative investigation method which we discussed with a number of students who read last year of high school. First, the interviews were aimed to let students talk about matters concerning religion and life. The next step was to examine their thoughts with a gender perspective as a starting point.

This case study attempts to examine how students of Religionswissenschaft at Södertörns University reflect about their philosophy of life and if their studies have some impact on their tendency to reflect. Also what aspects the students tend to reflect over will be investigated. In this study the term ?philosophy of life? includes humans thought and conceptions of the world and their outlook on mankind. To answer these question an interview study with 6 students took place, and the transcriptions produced 5 categories; ?The philosophy of life, to believe or not believe?, ?Development of concepts?, ?Outlook on mankind?, ?The founding of meaning? and ?Understanding and progress?.

This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.
