Individuell utprovning av inkontinenshjälpmedel i kommunala särskilda boenden

The purpose of this study was to examine the extent to which incontinence aids, used in local authority/municipal nursing homes, were adapted to the resident?s urine-leakage volume and to find out how nurses perceived the current situation concerning individual testing of incontinence aids in municipal nursing homes. The study method was a quantitative empirical study and was carried out in two phases. The first phase was a weighing test, carried out in three nursing homes, whereby the incontinence aids used by 25 residents during a 48 hour period were weighed. The second phase was the completion of a questionnaire by the municipal nurses working in the same local authority.

Hur påverkas VD : ns belöningssystem av ägandet? ? en studie av svenska noterade bolag

There is a strong debate in the media about the CEO compensation in the listed companies and whether they deserve their high rewards. Many previous studies have shown differences in the reward system depending on the ownership structure, mostly testing for only ownership concentration or ownership category. This study aims to investigate how the influence of the owners affects the CEO reward system, testing for both the level and the structure of the reward. The sample used in the investigation is Swedish listed corporations and consists of 251 observations. A survey was also conducted but due to low response rate and because the answers are not representative for the whole sample the survey will only be used as an illustration.

Inlösen eller extrautdelning?: En studie av sambandet mellan valet av kapitalåterföringsmetod och värdeskapande för aktieägarna

This thesis studies the stock price reaction around 68 announcements of special dividends and share redemptions on the Swedish stock market between the years of 2003 and 2007. We show that for the Swedish private investor, the tax effect of a share redemption is lower than that of a special dividend. Moreover, a share redemption could be interpreted as a signal of undervaluation. These two factors lead us to assume that the stock market would react more positively in connection to the announcement of a share redemption. We test this hypothesis through an analysis of the risk-adjusted abnormal return for the observations in the sample.

Testning för sexuellt överförbara infektioner efter oskyddat oralsex : Personalens attityd och kunskap

Aim The aim of this study was to investigate the attitudes of midwives and gynaecologists at youth health clinics about their own thoughts of risks with unprotected oral sex and testing of orally contagious sexually transmitted infections (STI). The aim was also to investigate the level of knowledge of oral STIs. One further aim was to examine what they thought about the level of knowledge about oral STIs among adolescents and how common unprotected oral sex is within this group and if oral STIs/oral sex is brought up in the form of information or questions during STI-testing.Method Seventy-five youth health clinics all over Sweden were randomly chosen. A questionnaire was sent by mail to the clinics. It included questions about attitudes, knowledge about STIs and information exchange.

Akustisk mätning av U-värde

This pre-study investigates the possibility of U-value measurements through an acoustic method. A hypothesis about an acoustic model built on acoustic theories combined with U-value theories is presented to answer the questions: ? Can U-value theory be combined with acoustic theories? ? Can the coefficient of heat be affirmed trough an acoustic measurement? The idea for this dissertation begun with a logical idea in mathematical similarity, between the coefficient of heat transmission units and sound intensity units. The U-value theory is based on assumptions such as initial resistance for inner walls and initial resistance for outer walls. The resistance in the material is interpreted through sound intensity theory. The argument is built upon mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB.

Sharepoint based applications, as well as design testing related activities to be incorporated into their existing software development framework. A test process maturity framework was chosen and applied for the design of the testing activities, while the test tool investigation resulted in guidelines on how to apply the tools effectively and circumvent any issues discovered..

Skola i förändring : Bra betyg = Bra demokrat?

Title: School in Change : Good Grades = Good Democrat? Level: Final assignment for Bachelor Degree in Political Science Author: Marcos Castro Allende Supervisor: Per Strömblad Date: 2013 ? May Aim: The background to this study is a book published by Staffan. I Lindberg & Richard Svensson where they presented a hypothesis that the decline in trusting democracy within Swedish youth is a result of the deregulation of the education in Sweden. The aim of this study is to test this hypothesis and see if the declinne in democracy can be seen already before graduating from elementary school. Method: The method used in this study consist of a survey distributed to students at two elementary schools that differentiates in question of grades and social status. By comparing and analyzing the results of this survey with the claims of the hypothesis, former studies and Lipsets theory of the working-class authoritarism a conclusion is made of the hypothesis credibility. Result & Conclusions: The results showed that there may be a a difference trusting democracy between students with higher grades and those with lower grades.

En beskrivning av manuellt test : Svagheter och styrkor med och utan stöd avett testverktyg

Test is an area in system development. Test can be performed manually or automated. Test activities can be supported by Word documents and Excel sheets for documenting and executing test cases and as well for follow up, but there are also new test tools designed to support and facilitate the testing process and the activities of the test. This study has described manual test and identified strengths and weaknesses of manual testing with a testing tool called Microsoft Test Manager (MTM) and of manual testing using test cases and test log templates developed by the testers at Sogeti. The result that emerged from the problem and strength analysis and the analysis of literature studies and firsthand experiences (in terms of creating, documenting and executing test cases) addresses the issue of the following weaknesses and strengths.

Kan företag genom sin redovisningsinformation påverka volatiliteten i aktiekursen?: en studie av sambandet mellan informationskvalitet och risk

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.

Automatiska GUI-test : En teoretisk och praktisk studie för hållbarare test

To automate software testing is an investment, and that makes it important to have good knowledge about automation before an implementation is made. In this master thesis a study about automated testing is carried out. The study also includes a closer look at the testing tool TestComplete. TestComplete is one out of many tools on the market that is developed for automated GUI testing and the goal is to get a picture of how well the tool can adjust to CC Systems own applications. Studies show that it is hard to write lasting test scripts.

Informationsflödets inverkan på marknadseffektiviteten: En studie av aktierekommendationers kurspåverkan över tid

Previous research has shown that the market reacts on stock recommendations. As the Internet has made financial information more available and cheaper to assess one could believe that the market reflects more available information today. If this is true the market will react less on recommendation made by journalists, which generally consists of processed public information. The stock market should thus be more efficient according to the efficient market hypothesis. This study examines initially if we can conclude that stock recommendations made by journalists generate returns above the expected returns, hence abnormal returns.

Effekter i samband med listförändringar : En undersökning på Stockholmsbörsen mellan år 2007-2014

Bakgrund: Marknadsanomalier har länge varit ett omdiskuterat ämne på aktiemarknader, en marknadsanomalie vilken denna uppsats har undersökt är listeffekter. Listeffekter är effekter som uppstår i samband med att företag förflyttas från en lista till en annan lista på en börs. Genom åren har det tagits fram möjliga förklarande teoretiska hypoteser till listeffekter, vilka är Efficient Market Hypothesis, Information Signaling Hypothesis, Price Pressure Hypothesis, Imperfect Substitution Hypothesis, Investor Awareness Hypothesis och Liquidity Hypothesis. Olika börser har olika regler för listindelning av företag och indelningen kan ha betydelse för aktiens förutsättningar. För att studera listeffekter genom listförändringar är det en fördel om listeffekten kan studeras i en miljö där det går att kontrollera för ny information.

VD-bytets påverkan på aktiekursen : En studie ur ett genusperspektiv

In the last decades the Swedish labor market has been characterized by a stereotype perception on women?s role and position on the market. The perception speaks of the characteristics of female leadership as being less qualified causing the gaps between the two genders to transform into a gender segregated society. The historically slow progress has limited the career opportunities for women to reach top management. However the increasing discussions during the 21st century on how to reduce the gender differences in the labor market has made it more acceptable with women on higher positions.

Funktionell testning av webbplatser : En fallstudie

Websites are often developed by small businesses, organizations or individuals which may lead to that the testing gets left behind; the focus is on getting a finished product that can be deployed as quickly and as cheaply as possible.Functional testing is important also for websites and a variety of aids exist. With the right tools and methods the development work is facilitated, and it leads to products with fewer faults.This report shows in the form of a case study how an appropriate tool for functional testing can be selected and how it can be used within development of a website. An analysis of the tools available is reported and JSystem is selected as the most appropriate for this case.It turned out that JSystem could not be used fully as intended in terms of deployment, but a well-functioning alternative solution was developed.A number of test cases were created without any unsolvable problems and JSystem performed well. In JSystem test cases in Java are created in Java, which gives a high flexibility..
