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.

The purpose of this study is to examine the expiration day effect on a stocks volatility due to stock option expiration, which is every third Friday in the month on Stockholm stock exchange. Volatility is the standard deviation of a stock. It measures the uncertainty about a stocks future movement. When volatility increases, the chance or probability of a stock going up or down increases. It?s a common rumor among stock traders that stock volatility tends to increase nearby expiration day.

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.

There is no standardized test to control the appropriate physical ability in the Swedish ambulance service. The county in question does not perform annual physical tests. A project has been going to develop science-based physical tests, designed for the ambulance service. The research has resulted in the Aasa-test.Objective: The aims of this study were to examine the ambulance staff perception of the Aasa-test relevance, introduction of annual tests and the importance of their own physical training in relation to ambulance work.Method: A quasi-experimental study with a comparative design has been conducted. Aasa-tests were conducted in 41 randomly selected staff at an ambulance station in central Sweden.

Generally prosody is described as the rhythmic, dynamic and melodic features of language. Prosody is further often described as suprasegmental, since its properties go beyond vowels and consonants, which are segmental characteristics of language. A relationship between prosody and music has been noticed and described for several decades. At present, there are several studies proving relationship between prosodic and musical abilities. The aim of the present study was to construct a test for prosodic non-linguistic perception and production regarding intonation and rhythm. The test was tried out on 16 children with typical language development aged 4;6-7;6 years. Before testing of ITAP each participant were asked about musical experience.

ABSTRACTBackground: On behalf of the Orthopedic clinic, Västerås, a study has been conducted with focus on comparing the results after conservative and surgical treatment due to complete achillestendon rupture.Aim: To compare results when testing the active and passive range of motion, calf muscle endurance, estimation of pain related to the achillestendon and self-efficacy to be physically active for individuals who have undergone conservative or surgical treatment after complete achillestendon rupture.Method: 14 individuals afflicted by complete achillestendon rupture in 2010 were recruited as a purposive sample. Examination were conducted of: Ankle range of motion with a goniometer, calf muscle endurance through a toe-raise test, estimation of pain intensity related to the achillestendon by VAS and self-efficacy to be physically active through ?Exercise self-efficacy scale?. P-value and the median were calculated.Result: The results of ankle range of motion and calf muscle endurance were based on the difference between the injured and the healthy side. When testing active plantarflexion the conservative group had a median of 4 ? and the surgical group had a median of 10 ?.

This report evaluates whether an interpreted high-level garbage collected language has enough information about its memory behaviour to make better cache decisions than modern general CPU hardware.With a generational garbage collector, depending on promotion algorithm and generation size, around 90% of all objects never leave the first generation. This report is based on the hypothesis that, because of the low promotion rate, accesses to higher generations are sufficiently rare not to benefit from caching.To test this hypothesis, we built an operating system with a Scheme interpreter in kernel mode, where the interpreter controls the cache. Generic x86 PC hardware was used, since it allows fine-grained control of cache decisions.Measurements of execution time in this interpreter show that disabling the cache for generations higher than the first does not give any performance gain, but rather a performance loss of up to 50%.We conclude that this interpreter design is not an improvement, but cannot conclude that the hypothesis is false in general. We suggest building a better CPU simulator to gather more data from which to make better caching decisions, moving internal interpreter data structures into the garbage collected heap and modifying the hardware to allow control in the currently rigid dimension of where data is cached---for example separate control of instruction and data caches and separate data caches for different areas of memory..

AbstractThe aim of this present study was to investigate whether there is a relationship between birth order and the personality trait narcissism using 181 individuals from Finnveden High School in Värnamo (115 females, 60 males, mean age 17, sd=0,94), in the context of the proposal of Sulloway (1996) that personality is influenced by the specialized nich-es siblings adopt in the quest for access to parental resources. A questionnaire which in-cludes Narcissistic Personality Inventory test, Birth order test and also Rosenberg?s self-esteem test in order to investigate if it might has an impact on narcissistic personality trait, was used. Results showed that there was no significant relationship between birth order and narcissism, however, a significant relationship between narcissism and self-esteem was found. Furthermore, there was a significant relationship between narcissism and the individual?s relationship with the mother.

Many companies have historically forced their interests through without any thoughts about the future needs of the humans and the society. In the last few years voices have been raised for a change, companies need to take their responsibility regarding sustainable development.The purpose of the report is to describe and explain possible relations between sustainabil-ity performance of companies and profitability, valuation, industry and size respectively.To be able to judge the sustainability performance of the companies Folksam (2006a) have been used. This is a solid investigation of the companies listed on the A- and O-lists of the Stockholm Stock Exchange by the end of 2005. The sustainability marks have been com-pared with the chosen key values for each hypothesis respectively. With this quantitative data as foundation, a quantitative approach and a deductive method have been used.In the first area of the investigation, profitability, the authors found correlation for the main hypothesis between sustainability performance and ?Return on Total Assets? through a statistical test.

Sweden is the country that has got the largest amount of elderly in the adult population in the world. The physical activity level decreases as we grow old and we experience muscle mass loss and a bone density reduction. This leads to an increased risk for falls and subsequent fractures. The purpose of this study was to investigate whether an exercise program could affect muscle function and balance ability to prevent falls. 17 women (age 64-79) participated in this study and was assigned to a control group (n=7) and an intervention group (n=10).

Purpose: The purpose of this thesis is to study the causal relationship between bank sector development and economic growth in four Nordic countries (Sweden, Finland, Denmark and Norway).Method: Our thesis is based on a quantitative method. The study consists of a compilation and analysis of key financial indicators that represent economic growth and bank sector development. A Granger causality test has been conducted on the time series in order to measure the causal link between economic growth and bank sector development.Theoretical framework: The study is based on the theory of endogenous growth and the causal relationship between bank sector development and economic growth also known as the demand following and supply leading hypothesis. Results: The results of the four countries are ambiguous. Except for Denmark, that follows the supply leading hypothesis, the remaining countries do not show a unanimous result..

The main aim of this research was to investigate four humour styles, affiliative, self-enhancing, aggressive, and self-defeating humour, and compare these with emotional perception. Forty-eight persons took part in the research, 27 women and 21 men living in the southern part of Sweden. Two humour tests were used: the Humour Scale Questionnaire ? HSQ, with 32 items, and a newly composed video test, assembled after pilot testing from 26 video clips, the Humour Video Questionnaire ? HVQ. To measure perception and interpretation of emotion, the revised version of the ?Reading the Mind in the Eyes? Test was used.

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.

This Master's Thesis describes the design of a new system where a digital signal processor has been added to an existing imaging system consisting of field programmable gate arrays. The new system will offer a higher degree of flexibility by considerably shortening the design time and make it possible to implement more complex algorithms than the existing ones. The choice of system architecture and a test implementation are discussed. The test implementation consists of a program for the digital signal processor and VHDL code for one of the field programmable gate arrays. The code for the digital signal processor was designed for testing on an evaluation board from Texas Instruments.

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.
