AP-fondernas utveckling : en jämförande studie om avkastning och risk mellan åren 2002-2010

Bakgrund: Det rådande pensionssystemet i Sverige består av sex så kallade AP-fonder. Genom åren har pensionssystemet flertalet gånger kritiserats för dess låga avkastning.Problem: Vår huvudfråga är att jämföra AP-fondernas risk och avkastning med aktiemarknaden som helhet, detta ska ske med hjälp av två jämförelseindex: MSCI World och SIXRX.Syfte: Syftet med uppsatsen är att jämföra de fyra första AP-fondernas risk och avkastning med aktiemarknaden som helhet under åren 2002-2010.Metod: Vi har använt oss av en kvantitativ metod, genom att samla in information från AP-fondernas årsredovisningar och hemsidor. Vi har samlat in historisk data, som vi sedan har bearbetat och analyserat.Slutsats: De studerade AP-fonderna har presterat sämre än aktiemarknaden..

Analys av nivåproblematik i dränagetank på Ringhals 1

The focus of this project has been on the drainage tank of the reheater on Ringhals 1. This tank has on two previous occasions received such a high water level that the system automatically emergency stopped. For this reason, events and various readings from these two occasions has been specifically studied and analyzed. In order to prove theories about what causes these problems a model of the system was created in the program Dymola. Using simulation results from the model, we have been able to demonstrate how the system's measured values should look likeunder normal conditions with respect to flows, pressures, temperatures, valve positions and water level in the drainage tank.

En jämförande studie av fluiddynamiken för olika fluidiseringsmedium i en kallmodell av en 100 kW-anläggning för kemcyklisk förbränning

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

Följsamhet till en kvalitetsnorm för fall- och fallprevention inom geriatrisk slutenvård : En studie baserad på journalgranskning

PurposeThe purpose of this study has been to investigate the documentation process following the guiding principles of the Quality Norms for Fall Prevention concerning fall risk assessment, risk identification, fall preventive measures, information and the making of an individual care plan.MethodThis study is a quantitative, descriptive and retrospective journal review study. There were 100 journals examine the existing documentation concerning fall risk assessment of patients who received treatment in geriatric patient care. The sample was consecutively.ResultsThe results showed that fall risk assessment was documented in 79 of 100 examined journals. 56 (71 %) of the fall risk assessments were made within 24 hours. In 59 of 100 journals the patient, relatives or former caretakers was asked whether the patient had had a fall within the last year, and in 61 of 100 journals it was documented that the nursing staff had made an assessment that the patient was going to have a fall during his or her length of stay if no preventive measures were set in.The majority of fall risk factors and fall preventive measures were documented within the areas of walking and transfer. It was documented that the patient was informed of fall risk, fall risk factors and fall preventive measures in 15 of 100 journals.

Foreign direct investments under political uncertainty : a case study of crop production in Ukraine

Intense competition among companies and luck or unavailability of certain resources in country of company?s origin force last to cross the borders, and start to hunt for new markets and cheaper inputs. However, by investing abroad the company is not only facing and dealing with cultural differences and new regulatory framework, but also becomes dependent on decisions and actions of different and to large extend unknown government. Moreover, the majority of the investments? flows are directed to developing countries, where power and capabilities of state authorities are considered to be more extensive than in countries of developed economies.

Datorspel = Lärande? : En kvalitativ studie angående gymnasieelevers attityder gällande datorspel som läromedel

The gaming market has become the fastest growing market for leisure and is one of the most popular forms of homeentertainment. This has generated a media debate about how people are affected by gaming and concernes how we are affected by the violence that may occur in games. Games proponents argues that gaming is the future of teaching and computer games are becoming a sustainable and popular instruction strategy. Some studies have long used computer games for educational purposes. By interviewing high school students in focus groups as qualitative research, I studied their attitudes towards computer games as a learning tool.

ECG-Screening for young elite athletesAbstractBackgroundSudden cardiac death (SCD) during physical activity is a frightening and emotional tragedy that draws huge media attentions when it occurs. Fortunately it is a relatively uncommon occurrence but happens nonetheless to young athletes who often seems to be in perfect health. SCD is used as a term for sudden unexpected complications on the cardiovascular system that leads to a deadly outcome normally within the first hour of onset of symptoms and the cause is some sort of underlying cardiovascular disease that gets triggered by physical activity.Normally athletes gets divided into two groups dependent on age, over and under 35 years, and this studies focus is on the younger group since it is often during this period athletes are at the elite level. It is also in this category the most unexpected sudden deaths occur that is not due to coronary atherosclerosis, which is the dominant cause of death, and drastically increases, for people over 35 years old.AimThe aim of this study was to scientific and unbiased analyze peer-reviewed clinical articles todescribe the pros, cons and cost to implement an ECG-screening as a standard before physicalactivities for specifically defined elite athletes.MethodA systematic review was performed and after all data collection 21 articles was chosen to beused as a base for both background and analyze. At the end 10 articles was fulfilling the criteria to be used at the analyze and later the results.ResultsThe implementation of ECG-screening has reduced SCD in Italy by 89 % between the years 1979-2004.

Livsstil och livskvalitet året efter avslutad hjärtrehabilitering : en enkätstudie

ABSTRACTBackground: To be stricken with a cardiac infarction is among other things linked to different risk factors.  Many studies show that the participants in cardiac rehabilitation programs learn to deal with the risk factors, increase their quality of life and lessen the risk for re-infarction.Objective: To describe the lifestyle and perceived quality of life of the individuals after having participated in cardiac rehabilitation program and to see if they had maintained their results up to a year after having a cardiac infarction.Method: The 19 individuals who had participated in cardiac rehabilitation in 2010 after having had a cardiac infarction were asked to participate in the study. Everyone agreed to participate. The study was made analyzing the surveys, one a locally made, that the individuals had filled out four and eight months after cardiac infarction, and the other the generic Quality of life questionnaire EQ-5D, that the individuals had filled out two and twelve months after cardiac infarction. Result: The individuals have not changed their lifestyle after having participated in cardiac rehabilitation which can be interpreted that they have followed existing recommendations. The mean weight increased with one kilogram, no depression is shown and they stress less.

Olika metoder och tekniska hjälpmedel för att bestämma bevattningstidpunkt :

This examination work on studies and research in articles is mostly from other countries. The purpose of the examination work have been to find out if there are any means you can work with to find out when its time to start irrigation, how they works and if they are credible. In Sweden there is not many means for decide when it?s time to irrigate and how much water you should appear. Swedish farmers think they have so much experience that they don?t need techniques like this.

Därom tvista de lärde : en analys av kvalitetsbegreppet och dess betydelse fö utformandet av bibliotekets inköpspolicy

In public libraries there seems to be an unspoken consensus on what literary quality is. At the same time librarians are always eager to express the opinion that quality lies in the eye of the beholder. Quality is, it is said, something that you don t have to define. But at the same time it s up to everyone to decide what quality means to them. What I have been missing from the discussion in libraries about literary quality is a theoretical awareness about what it means to divide literature into higher and lower spheres.

"Man kan undra vad man utsätter sig själv för egentligen" : Socialsekreterares reflektioner kring psykisk påfrestning i yrket och hur den kan hanteras

The focus of this essay is to further investigate and describe psychological strains experienced by child welfare workers. The method used was qualitative interviews, two group interviews. The research aimed to understand how child welfare workers were affected and handled the psychological strains generated by work through theory of coping and symbolic interactionism where humans are viewed as pragmatic actors. The research showed, as previous studies shown, that the child welfare workers experience a great deal of psychological strains generated by high turnover in staff and pressuring work demands. The child welfare workers felt inadequate and alone in their work tasks and experienced stress and anxiety.
