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.

Prior studies have shown the relationship between capitalised monthly fees and sales price for tenant-owned apartments in Stockholm. However, few studies have been conducted explaining the effects of capitalised monthly fees over time and how it has changed with, for in-stance, increasing sales prices and fluctuating interest rates. The aim of this study is to deter-mine if the effect of capitalised monthly fees on sales prices of tenant-owned apartments has changed between 2006 and 2014, in Vasastan/Norrmalm in Stockholm. The study shows that there are statistically significant results indicating that capitalised effect of monthly fees on sales prices has in fact changed over the studied time period. The results differ with apartment size (number of rooms) and the conclusion is that there is an effect of time on one, two and three bedroom apartments but not for apartments with four bedrooms or more..

Background: The devolopment in the exchange market has attract a large number of investors. The information flow is extensive and it might be hard to follow the dynamic market. Some investors therefore choose to place their capital in a stock portfolio which is manged by a professional firm with no influence from the capital owner, this management is called discretionary managing. Purpose: the purpose of the thesis is to examine the working methods and the rationality regarding the management of the discretionary portfolios. The purpose is also to try to examine whether there is a relation between the selected risk, return and fees.

Redan i samband med Kreugerkraschen i början av 1930-talet började man ifrågasätta och ställa krav på revisorers oberoende. Problematiken kring revisorers oberoende är än idag en högst aktuell fråga. Effekten av en revisor som inte förhåller sig oberoende kan vara att företagets intressenter förses med information som inte är rättvisande. Bakomliggande faktorer som kan påverka revisorers oberoende är revisionsbyråns arvoden och klientföretagets storlek. I denna studie kartlägger vi andelen orena revisionsberättelser och going concern-varningar hos företag som gått i konkurs.

The theme of this essay is the principle of free access to the Swedish Public Libraries, and its aim is to fmd out the opinion of adult visitors of such libraries as regards the introduction of fees on the borrowing of books, already existing fees such as reservation fees, charges for interlibrary loans and charges for the late return of books.The main part of our survey comprises questionnaires that were handed out to 100 visitors at the Norrkoping City Library and 100 visitors at the Eskilstuna City and Provincial Library. In order to illustrate the fee problem from another angle, interviews with staff people from the two libraries were carried out A large part of the essay consists of material aiming to give a general picture of the subject, e.g. how the "free of charge principle" is tied to the Swedish library system, what arguments have been presented to maintain or reverse this principle, and a comparison of the relative situation in other countries. As the conception of popular education is so basic for the "free of charge principle", we also account for the idea of popular education.The result of our questionnaire shows, among other things, that 60,9% cannot consider paying for any of the free services offer by the libraries today, 21,3% answered that they could possibly consider paying for some of the services and 17,8% answered that they didn't know. 76% would rather pay for a library card than stop borrowing books altogether..

The Swedish Tax Agency is a government authority whose mission is to collect taxes and fees for financing the public sector and welfare in Sweden. Under the last decade the tax gap in Sweden has been constant and small businesses with a max turnover of 25 millions Swedish crowns are the biggest group in the tax gap. In the government inquiry about abolishment of statutory audit for small businesses (2008) there has been laid some proposals that the Swedish Tax Agency should get new control tools and increased rights to control small businesses tax accounts. In the science some controversies exists about tax authority?s ability to get taxpayers to pay taxes and fees to the society through using deterrence and compellence control methods versus more service? This ground has guided us to our presentation of a problem: ?How the Swedish Tax Agency works with influencing small businesses behaviour through preventive actions and controls?? The purpose of this study is to research and understand how the Swedish Tax Agency works in their control activities to influence small businesses behaviours regarding taxes and fees.

In 1994 the EU directive of packaging waste was adopted. The result was that all EU member states developed different systems to manage packaging waste and recycling. This paper examines the various systems and the factors that affect the level of recycling. This is done by a cross-sectional study between countries. The results of my study suggest that take-back system generates less recycling than other systems, the mandatory deposit system can affect the recycling in a positive way.

Detecting small signals with a comparator demands that the total voltage offset is lower than the actual signal. The total offset includes the voltage offset in the comparator and the voltage offset that is created by the offset currents that flows thru the load at the comparators input. The goal with this comparator that has been developed has been that it will have a total voltage offset at maximum 500 uV. The comparator does not need to be extremely fast or does not need to operate in a big frequency area. To have all the flexibility that is needed a full custom technique is used.

AbstractObjectivePatients with Parkinson?s disease often have symptoms of dysphagia. These swallowingproblems have consequences for quality of life as well for the physical wellbeing of thepatients. AimThe aim of this study was to describe and correlate Swallowing Quality of Life (SWAL-QOL)scores, self-assessment of swallowing function using a visual analogue scale and the resultsfrom a fiber endoscopic evaluation of swallowing function in patients who had been selectedfor Deep Brain Stimulation in caudal zona incerta. A secondary aim was to correlate diseaseduration with results from SWAL-QOL and the fiber endoscopic evaluation of swallowingfunction.MethodTen male Parkinson?s patients (age 45-69 yrs, median 61.5 yrs) who were selected for DeepBrain Stimulation completing the Swallowing Quality of life form, as well as rating theirswallowing function using a visual analogue scale and undergoing a fiber endoscopicevaluation of their swallowing function.    ResultsThe median total SWAL-QOL score was 94% while the mean was 91%.

ABSTRACTThe aim of the observation study was to examine the dental hygienists working tasks and the time they used carrying them out. Four dental hygienists where observed during four days each. The total time the dental hygienists used with patients during sixteen fulltime days come to a sum of 89 hours of the possible 111 hours. Twelve hours was late cancels and time when patients didn?t come to their appointment and ten hours were used for meetings.

The hybrid larch (Larix x eurolepis Henry) is a fast growing tree species and was introduced in Sweden for about 50 years ago. The high growth and expected resistance to diseases are probably the main reasons of introducing the tree species into the Swedish forests. The purpose of this thesis was to document the production of hybrid larch planted in the Snogeholm landscape laboratory and to compare the production in the pure hybrid larch stand with the mixture together with pedunculate oak (Quercus robur). The data collection in Snogeholm since the establishment has been carried out by the Swedish University of Agricultural Science (SLU). The fieldwork for the thesis was carried out in 3 stands, containing hybrid larch, pedunculate oak and a mixture of hybrid larch and pedunculate oak, in order to be able to compare the total stand production of the areas. The results show that the total production of hybrid larch in the mixed stand only is 35 % compared with the total production of hybrid larch in the pure stand. Therefore, the hypothesis that the total production of hybrid larch is equal to the planted mixture with pedunculate oak was rejected. The other hypothesis that the total production of a 2 hectare large stand containing a mixture of hybrid larch and pedunculate oak would be greater than the total production of two pure stands of 1 hectare containing hybrid larch and oak each was also rejected. In the studied case the total production was 45 % greater if hybrid larch and pedunculate oak was planted in pure stands. The results from the case-study only indicate that the total production of hybrid larch and oak under the investigated conditions can be higher when planting the two species in pure stands compared with a mixture of the two species.

Title: The municipal school of arts and music - "a school for everyone?" - A study of the accessibility of "Kulturskolor", focusing on the absence of fees. The aim of this thesis is to increase the understanding of a complex of problems concerning broadened recruitment of students and teachers in "Kulturskolor". I have chosen to focus on three schools of performing arts offering programs free of charge to ascertain how they work with broadened recruitment and to see what effects they have achieved by having no fees. I have examined these schools through a qualitative study where I have interviewed the principals and teachers from each school.

The main environmental problem for aviation is the great amount of exhaust gases, mainly nitrogen oxides, carbon monoxide, carbon dioxide and hydrocarbons - mostly "greenhouse gases" leading to climate changes. I decided to sort out what is being done to decrease these problems and what regulations there are concerning air pollution by the means of searching the internet and using publications from aviation authorities for current figures. I chose to scrutinize authorities on political, authority and company level, resulting in summarizing the work of UN and EU respectively, ICAO (International Civil Aviation Organization), JAA (Joint Aviation Authorities) and LFV (Swedish Civil Aviation Authority), and finally SAS, representing the airline companies. Conclusion that I have drawn are thatthere are regulations for air pollution, written down in ICAO's Annex 16, that are to be followed. Secondly, LFV are environmentally controlling their nineteen airports and since economy is an important reason for not giving priority to environmental issues in aviation emission charge and noise charge are added to the landing fees.

Introduction:By insight in the company and by monitoring the management, the board has an important function in creating trust in governance of the company. Furthermore, the board reduces the asymmetry of information between the owners and the management, which also is the function of the auditor, by auditing how the board governs the company and the accounting. In case the board does not effectively monitor the management, the auditor has to extend its monitoring, which increases the owners agency costs through the audit fee. The board composition can affect how effectively the board practices the monitoringProblem: How is the audit fee affected by the board composition?Purpose: The purpose of this study is to explain how the board composition affects the audit fee.Method: The study uses a quantitative method, where the data was collected from the annual reports of 112 limited companies listed on the NASDAQ OMX Large and Mid Cap lists on January 2, 2012.

Den svenska rennäringens primära inkomstkälla är försäljning av renkött. Syftet med denna uppsats är att undersöka ett antal faktorers inverkan på utbudet av renkött. Metoden ordinary least square har använts för att göra en ekonometrisk studie baserad på statistik för åren 1980-2003. De faktorer som testats är total ersättning, vilken inkluderar avräkningspris samt kvantitetsbaserad subvention, och renstammens storlek. Resultaten i vår undersökning visar att total ersättning inte är signifikant på någon testad nivå, däremot fann vi att renstammens storlek hade positiv korrelation med utbudet på renkött.
