Even minor health effects may be important for the whole population. Stroke patients require the largest number of days spent in hospitals and nursing homes than any other medical condition group. Risk factors for stroke include smoking, high alcohol intake, physical inactivity, hypertension, hypercholesterolemia, high waist-hip ratio and diabetes.

The purpose of this paper was to examine the potential presence of a relationship between the quality of corporate financial disclosure and the volatility in stock price in the Swedish market. This was carried out by investigating the hypothesis that an accurate annual report with high information quality results in a decrease in volatility. Previous studies have been done with this approach and in some cases the above stated hypothesis was found to be true. Thus, in the absence of a perfect efficient market the level of information quality may to some extent explain the volatility in stock price. However, the result of our study gave no evidence in support of this hypothesis.

Active ownership is widely regarded as positive for the development and performance of businesses. In this paper, we investigate the impact of ownership concentration and owner identity on return on equity (ROE) in Swedish companies between 1986 and 2008, and show that active ownership might suffer from opposing effects. We find evidence, albeit weak, that ownership concentration has a positive effect on profitability, but that it levels off at high levels of ownership shares. Furthermore, we propose that family ownership has a negative effect on profitability. Our results are dependent of choice of statistical method, but show nonetheless a need to reevaluate what seems to be a universally positive view of active ownership..

In this study, we examine the presence and consequences of CEO overconfidence in the Swedish market. We identify overconfidence with two insider-trading based measures and find that overconfidence is apparent among one third of CEOs in companies listed on the Swedish stock market. We also find that these CEOs are more prone to carry out acquisitions, as the probability of conducting an acquisition increases by 27 % if the CEO is overconfident. However, we do not find evidence that acquisitions by overconfident CEOs are more value-destroying. This finding contradicts results from previous studies conducted on Anglo-Saxon markets that suggest that overconfidence has a negative impact on the value-creation in acquisitions.

The DuPont formula is one of the most well known and basic tools used for financial statement analysis and is highly useful for understanding firms strategies and operating environment. Previous studies on American listed companies have also shown that analysis of the changes in the DuPont components is useful in forecasting contexts. In this thesis we test whether disaggregating the change in return on net operating assets provides incremental information about future performance for Swedish listed and not listed companies. We find that the change in asset turnover is a leading indicator of increased profitability for both listed and private companies, regardless of size. We also find evidence that the usefulness of the disaggregation for understanding future performance is greater in capital intense industries and lesser in service industries..

Sjuksköterskornas arbetsvardag bestod av att ofta möta lidande och död hos sina patienter. De behövde i sitt arbete strategier för att hantera sina psykiska och känslomässiga reaktioner. Syftet med arbetet var att undersöka sjuksköterskans reaktioner och bearbetningsmetoder av traumatiska händelser uppkomna i arbetet. Metoden var litteraturstudie. Artiklarna analyserades enligt Evidence Based Nursing (EBN) gjord av Flemming (1998).

The aim of this essay was to gain a deeper understanding about how school employees interpret and practice school law regarding cyber-bullying that occurs between pupils on the internet. To examine this we used a qualitative method. We completed eight interviews with five teachers, one headmaster, one school welfare officer and one special educationist. These eight school employees were from four different high schools. In our interviews we found that the school employees thought it was difficult to define different concepts within the school law such as in association with the occupation and offensive behaviour which prohibits them from interpreting the school law in the same way.

AbstractThis study has two aims:[X] to create an analytical framework consisting of factors that might trigger terrorism[X] to apply the analytical framework on the case of IRA, in order to be able to examinewhich factors that exist behind the appearance of terrorism in the current caseTo reach the first aim the author has studied the theoretical discourse on the complexed issueof terrorism. This has constituted the point of departure for the creation of an own analyticalframework. The purpose of the framework is to bring clearness to why terrorism appears. Theanalytical framework is not only suited for application on the case of IRA, but for applicationon terrorismcases in general. To reach the second aim the framework was applied on the caseof IRA.The aims of this study have been fulfilled through the method of qualitative text analysis.

Intramuscular injections to cats can generate strong reactions in some individuals while reactions of the same extent, according to the author, not always are recognized when using the subcutaneous route. The reactions are probably caused by fear, stress and/or pain. When the injection can generate pain one has to take that into account, which can be a limitation in treatment. It is well known that injections generate pain, but knowledge about the cause and processes of the injection-associated pain is limited. This is mainly due to the difficulty in finding objects to study pain on, high cost of use of laboratory animals and difficulty to obtain objective measurements. Although there is evidence that there may be a local muscle injury by intramuscular injection, it is not always that the extent of damage is related to the pain experienced. Facts about the causes of injection-associated pain have been studied in a literature review.

The purpose of this thesis is to ascertain the main determinable factors of Swedish SMEs capital structure decisions and to investigate whether existing capital structure theories are applicable on Swedish SME financing. We have used panel data to run regressions of various capital structure determinants on three measures of capital structure; short- term debt, long-term debt and total debt. We found that growth opportunities, profitability and age are the most important capitalstructures determinants for our sample. Firm size shows a small explanatory result but the effective tax rate and the asset tangibility do not seem to explain the capital structure at all. Thematurity matching principle is considered significant..

The aim for this bachelor thesis was to form a deeper understanding of librarians? occupation and professional identity and therefore we have examined library students? and educators? view on professional identity, competence and career possibilities. Our take on this was that there seems to be little interest in managerial positions and we asked ourselves why this is and if we could see a change in interest in the librarians to become. As our theoretical framework, we chose Andrew Abbott?s, 'Theory of Profession'.

The purpose of this study was to examine earnings quality and earnings management in U.S. ex-post failed firms. A quantitative study was made, using the Modified Jones Model, to identify abnormal accruals up to six years before bankruptcy. 9 003 continuing firms and 187 bankrupt firms, active sometime between 1990 and 2010, were examined. The study concludes that U.S.

Twenty-four calves, which had not grazed previously, were divided into four groups. They were subsequently inoculated orally with either E. alabamensis oocysts, O.ostertagi/C. oncophora larvae, or both. One group remained uninfected and was used as a control.

This paper aimed to investigate how Swedish politicians use social media Twitter and Instagram and if there was evidence to discern of personal branding and identity creation. Main method used was the observation of four politicians? shared content on Twitter and Instagram. In order to strengthen the results of the study, interviews were also made on the same politicians, of which two responded. The study showed, among other results that Twitter is used more for political aspects and Instagram to show personality and lifestyle.
