Reglering av naturgasdistributörer : En undersökning av benchmarking på marknaden för naturgasdistribution
This paper discusses the advantages and disadvantages of using different benchmarking models to measure and compare the efficiency of Swedish gas distributors. It also discusses to which extent the results of a benchmarking study should influence the revenue-cap which will be implemented in the gas distribution sector in Sweden from year 2011. The discussion is based on arguments from both theory and practical applications of benchmarking. The results suggest that benchmarking Swedish gas distributors against distributors in another country using a parametric model is most favorable, but the reliability will be increased if non-parametric models are used also. Partial and total productivity measures could be used to confirm results of other benchmarking analyses.
Stabilitetsberäkningar och åtgärdsförslag vid islast på Skålandammen
Hydropower is an important source of energy in Sweden and accounts for about 46 % of the total energy production. Sweden has about 1 200 hydropower plants and with the intention of raising the pressure head of the water and to store water, dams are built by the power plants. The storage reservoirs make it possible to adjust the energy production by demand and season. Dams in connection to the reservoirs are subjected to additional loading during periods of high floods or when an icecap in the winter is formed on the reservoirs. In order to maintain the dam safety, the power companies in Sweden are working with guidelines for dam safety from RIDAS.
Humankapitalets roll vid företagsvärdering
This study investigates a method for identifying human capital and its effect on company valuation. We devise a measure for the efficiency of human capital based on the personnel cost. We include all companies listed in the financial and industry sector on Nasdaq OMX Stockholm in an attempt to examine human capital and its effect on firm valuation. Our results indicate that a higher efficiency of human capital has a positive effect on return on assets. However, we find that our measure can be interpreted in two ways; either as a firm?s level of human capital efficiency or its dependency on human capital, to achieve its net sales and revenue.
Is the Use of the Rubber as a Preventive Measure to the Spread of HIV/AIDS Morally Justifiable? Ethical Reflections on the Controversy
Since the Human Immunodeficiency Virus (HIV) that causes Acquired Immune Deficiency Syndrome (AIDS) was discovered in the 1980s, the condom has scientifically proven to be the only technological device that can prevent transmission of the virus during sexual intercourse. This technical approach to the HIV has strongly emphasized that prevention is only possible if the condom is properly used. However, as a technological artifact the condom has shown that its use is laden with values. The question of values on condoms has brought in a heated debate on the moral justifications of its use. In Malawi, just as in other African countries, the Faith Community has rejected the Governmentsplea to promote condoms as the preventive measure against the virus.The Faith Community has emphasized on abstinence and mutual faithfulness as the only reliable means to the prevention of HIV/AIDS.
MCNP-modell för beräkning av neutrondos och DPA på reaktortanken vid Ringhals 2
In this report an MCNP (Monte Carlo N-Particle) model is described for the reactor vessel at Ringhals 2. The model is validated against the specific activity in neutron dosimeters, extracted in 1977, 1984 and 1994. The validation showed that the calculations of the model are within the requirements of a maximum of 20 percent uncertainty for every neutron dosimeter except one, extracted after the first cycle. The uncertainty of this cycle was mostly due to the operation data rather than to the MCNP model.The model has been used to investigate various questions concerning radiation damage. The reliability of the traditional measure of radiation damage, fast neutron flux (En > 1MeV) has been evaluated. This has been done by taking the ratio for this and another measure of radiation damage, DPA (Displacement Per Atom), for various positions and layers.

Biomekanisk mätmetod och ergonomisk analys av träningsmaskiner
To get the maximal output of your exercise in gym machines, there are different factorsto be considered. For example the strength of the muscle varies dependent on the positionof the muscles. To get the best results of the exercise the load has to reduce and increaseat specific positions.This study was made in cooperation with Caretaker Scandinavia AB, a company forsales, marketing and development in health care. They are general agent for Nordic Gymwho works with manufacturing of equipment and machines for gym and fitness.The aim of this study was to generate a method of measurement to evaluate and controlthe biomechanics of Nordic Gym´s workout equipment. A protocol for an ergonomicanalysis on the equipment has also been elaborated.One of the methods to measure the biomechanics was to measure the torque through thewhole movement.
Kan fotboll r?dda unga personer fr?n kriminella g?ng? En kvalitativ studie g?llande fotbollstr?nares upplevelser av att anv?nda fotboll som brottspreventiv ?tg?rd i utsatta omr?den.
This paper aims to increase the knowledge about the relationship between football and social
sustainability by investigating football as means of crime prevention. In recent times, Sweden
has faced a situation where there is an increased level of young people involved in criminal
activity. The government has formulated various strategies to deal with the situation and a
specific part of civil society that has been given a prominent role within the crime prevention
strategy are football associations in socio-economically vulnerable areas. This study therefore
examines football coaches' experiences of using football as a crime prevention measure in
socioeconomic vulnerable areas. The data has been collected by qualitative interviews with
three football coaches.
Tillit, förtroende och misstro : En kritisk granskning av enkät- och frågeformulär som använts inom statsvetetskaplig forskning
In this paper I have conducted an analysis to critically examine survey questionnaire forms used in political research to measure trust and distrust. During the first step of the analysis I aimed to identify how the concepts where used in the forms. The second step involved examining if it was possible to relate the questions and items to five theoretical assumptions based on theories of trust (and distrust). The third step was to examine the quality of the forms, in relation to survey and questionnaire designs.The results of the analysis showed that the institutes that conduct the studies tended to use similar questions to measure trust. Some of the forms that where analyzed had very many questions, which could lead to exhaustion for those participating in studies.
Att säkerställa god språkutveckling i förskolan : En undersökning om hur pedagoger arbetar för att främja varje barns språkutveckling
The main purpose of this study was to examine how preschool teachers are working to promote each child's language development and whether they can ensure that they do that. Therefore I wanted to find out what a good language development implies for each teacher, how they work to promote each child's language development in daily practice, how they measure the actual language development and also what conditions the teachers have, to engage in a language development way to work. For the study, I chose a qualitative method, with structured interviews and all together I interviewed six preschool teachers, within the same organization in a suburb close to Stockholm. The results showed that there is an ambiguity, among the preschool teachers, in what a good language development means, but it can be stated that they do have a language development way to work even if it needs to be developed. Further on, it has emerged that the teachers have the tools to measure children's language development, although they do not have the conditions yet to use the method to the fullest. About the preschool teachers own conditions in order to operate in a language development way to work, I concluded that they have a strong foundation to build on, but they still have much work ahead of them.
Evaluation of four methods for the assessment of joint swelling in dogs
Evaluation of joint swelling is an important part of the orthopedic examination and can be used to follow a patient?s progress during rehabilitation and therapy. Usually a swelling is assessed by palpating the joint but a more objective, but still easy to use, method would be preferable.This study seeks to increase the knowledge in veterinary rehabilitation by validating four different measurement tools (three recognized and one novel) for the assessment of elbow joint swelling: palpation, tape measure (circumference and figure eight measurement), slide caliper (craniocaudal and mediolateral positioning) and tonometer. This was achieved by calculating the inter- and intra-rater reliability and correlating the results from the different measurements with each other.The methods with best inter- and intra-rater reliability as well as good correlation among themselves were shown to be slide caliper with craniocaudal positioning, circumference and figure eight. Additional studies, with a larger and more diverse material, ought to investigate these methods further..
Initial evaluation of the Meritas Troponin I test for measurement of equine cardiac troponin I
Cardiac troponin I (cTnI) is considered a specific and a sensitive biomarker of cardiac disease, and due to a high inter-species sequence homology; human cTnI assays can often be used in veterinary medicine. The main aim of this study was to perform an initial evaluation of a human cTnI test, the Meritas Troponin I test, for measurement of equine plasma cTnI, in order to investigate whether the test could be a possible subject for a more comprehensive validation. The hypothesis was that the test could measure equine cTnI, as there is a good homology between equine cTnI and human cTnI.
The evaluation included a dilution parallelism, an intra-assay precision study and measurement of plasma cTnI healthy horses. In the dilution parallelism and the intra-assay precision study, equine plasma with previously established high cTnI concentration, according to another cTnI assay, was used. In addition, cTnI concentration was measured in plasma, collected from 19 horses, without signs of disease at physical and ECG examinations.
The obtained curve in the dilution parallelism was linear, indicating that the Meritas Troponin I test can be used to measure different concentrations of equine cTnI in plasma.
Institutionella ägares inverkan på redovisningskonservatism - En empirisk studie av företag noterade på Stockholmsbörsen
The increasing holdings by institutional investors have raised concerns about the institutions passive investment strategies and the implications for corporate governance. A way for investors to address moral hazard and opportunistic behaviour of management is to demand conservatism in accounting practices. This paper analyses the relation between institutional ownership and accounting conservatism in the Swedish market by studying firms on the Nasdaq OMX Stockholm over a three-year period. Furthermore, the study investigates whether ownership by institutions with high probability of monitoring managers leads to higher conservatism in financial reporting. To measure accounting conservatism this study uses the asymmetric timeliness measure developed by Basu (1997).

Delat ansvar för ett enat Sri Lanka: asymmetriska relationers påverkan på fredsprocessen
Since 1983 the people of Sri Lanka has endured an ongoing Civil war, however the intencity has varied over the years. The aim of this theses is to examine what influence the asymmetric relationship between the Sri Lankan goverment and the Liberation Tigers of Tamil Eelam (LTTE) has on the process of negotiating a solution to the civil war. I am also examining whether the asymmetical relationship has changed over time and if these changes have had any effect on the process.To analyze the asymmetries I divide them into material and non-material. I measure the material asymmetries in economic and military resourses, and to measure the non-material I use indicators such as commitment, alternative, controll and legitimacy.The results show that the asymmetrical relations between the parties in Sri Lanka have changed since the 1990s. Factors like 9/11 and the recurrent suicide bombings by the LTTE has had a great influence on the singalese-tamil relationsship.
