Background: Testosterone is the most important androgenic hormone in the male. Aging is closely associated with reduction of serum testosterone which can lead to reduced muscle mass, muscle strength, bone density, and depression. These symptoms may be counteracted by administration of testosterone. Objective: The purpose of this study was to examine the effects of hormone replacement in men with age-related testosterone deficiency. Method: We performed a systematic review using Randomised Controlled Trials (RCT).

The purpose of this masters thesis is to examine how librarians work in a literary educational role with literary circles for adults and youth, in public libraries and at school. The study also examines whether participation in book discussion groups has any effect on participants and librarians regarding changes in reading habits and in personal development. Another aspect investigated was how participants experienced the atmosphere in the group. We have conducted qualitative interviews with five librarians who have lead different literary circles and with two participants from each literary circle. In all 13 interviews were conducted.

Unga möter unga is an activity that concentrates on sexuality, coexistence and relations. The project was founded by ?Ungdomsmottagningen centrum?. Ungdomsmottagingen centrum collaborates with the University of Gothenburg in implementation. When us students of socialwork programs have our practical vocational training place during term six we get the possibility to choose to participate on this activity aside of our other practical training.

Studies have shown that politicians are significantly more likely to become victims of violent crime than other citizens in Sweden. In fact increasing political rank and engagement are directly proportionate to increased risk for violence. Threat towards politicians is not only dangerous to the individuals involved but also to the democratic system as a whole.Political scientists the world over have done a lot of research on democracy, but I have been unable to find a single method or theory that examines how violence, threat and harassment affect political leaders and democratic systems.The aim of this study is to expand the existing model made by Tommy Möller, professor in political science. In his model he presents 11 factors that affect political leaders ability to act. My aim is to develop his model by adding a 12 th factor ?violence, threat and harassment?.

The main purpose of this two year master´s thesis is to study patterns, structures and relations within gender studies when combined with Library and Information Science(LIS). Further aims are to determine the character of student work considering, occurrence, gender and main theme, to study the progress of the intellectual base of gender studies within LIS and to evaluate the use of bibliometrics as a tool for researching the development of a discipline. To achieve these aims, a bibliometric study using both publication analysis and citation analysis, is carried out. The studied material contains student work, specifically focused on gender, from the Swedish School of Library and Information Science (SSLIS) from 1985?2012.

This thesis has its focuson media portrayal of a large political institution; the European Union. Articles from two nations daily newspapers have been analyzed in order to examine how the European Union is described and framed for their readers. The newspapers that was chosen for this study and from which the material was collected, were the Swedish newspaper Svenska Dagbladet the American newspaper The New York Times. The material was taken from three periods of time, and by this the results did not only serve a presentiment on how the media reports about the subject, but also an idea over the media?s coverage character over time.

In this thesis I have chosen to study the use of crowdsourcing in Swedish archival institutions as well as the influence this methodic platform has on the work of modern archivists. This also raises the question whether the nature of the platform is in any way influenced by the attitude working professionals might have towards crowdsourcing as a legitimed working method. This investigation is based on case studies and interviews with archivists from select Swedish institutions and also the methodology of two now ongoing crowdsourcing projects.The theoretical framework on which this composition is based comes from the work of Gregory Asmolov and his work on crowdsourcing platforms and their functionality as tools of governing. Cultural-Historical Activity Theory (CHAT) is applied to analyze how the method of crowdsourcing is utilised by archival institutions and influenced by their daily routine in conjunction with Governmentality as the chosen way of studying how these platforms might control their users.From the results of the performed case studies, two discourses emerged based on the view on quality concerning gathered information amongst the involved subjects. The first of these discourses places it´s trust and faith in users themselves where validity is of a lesser concern than the actual availability of information through the concept of ?wisdom of the crowds?.

The issue about how Scania shall perform HVAC tests in the climatic wind tunnel CD7, which Scania is about to complete by year 2013, has resulted in four test methods for truck HVAC and also a test method structure. The test methods have been chosen to focus on sun, snow and rain simulations. These are adapted and developed according to what should be tested and to what can be tested in CD7, which has been the object. With CD7 different climates can be simulated in a controlled environment for complete truck level, from desert with high sun load to arctic cold and snow.The test methods represents a basis to start from, for designers and test engineers which make the testing more repetitive as well as time eventually can be saved. Before the test methods can be applied they must be verified as they are based on theoretical and empirical assumptions.

This essay, called Motivation and reading comprehension, is a study of the correlation between the motivation to read and the reading comprehension of Swedish students in their final year of school before university level, meaning that they are eighteen or nineteen years old, sometimes more.The relation between the identity of the individual and the learning process has been a matter of scientific interest for some time, and this essay works in that tradition by investigating the connection between how pupils regard reading and how well developed their ability to decode text is.The reading comprehension is measured through a test that consists of a text from the Swedish epic by Vilhelm Moberg, Invandrarna, where the reader at certain intervals throughout the text is asked to mark the correct word from a choice of three. This test has been used and evaluated extensively by Per Fröjd, who has found that the results are reliable and useful.To measure the motivation to read I?ve constructed a survey to be answered before taking the reading test. It focuses on three different parts of reading motivation that are noted as the most important ones by Ivar Bråten. These are the feeling of joy and interest for reading, the goal to acquire knowledge of a specific subject, and the expectations that you have on yourself as a reader.Results show a weak or non-existent correlation between the two factors for the whole of the subjects, but once those who have a first language other than Swedish are removed the correlation becomes significant.

The division of Engineering Materials at Linköping University, department of Management and Engineering, conducted a research project concerning Fatigue life of thermal barrier coatings during 2009. During this project equipment to provoke these fatigue failure by rapidly heating and cooling test subjects in cycles, was ordered.Design and manufacturing of the equipment was handled internally at LIU.The equipment was built using a furnace that is lowered and raised over the table where the test subject is placed. To keep the temperature of the furnace a lid slides in place to close the downward facing opening of the furnace when it is in the raised position. On this door there is nozzle that is used to cooling of the test subject by air.To make sure that the equipment can work independently you need an automation controller that can evaluate if movement can occur without danger of collisions. The control system also needs to monitor that all elements are performed according to plan.This degree project is based on a modular system from OPTO 22 and includes the configuration of a PLC that will be supplied with logic and a user interface.The degree project resulted in a graphic interface in which a user can set desired values for different parameters and get information about current values for them.

Introduction: Dolomite AB was in need of a dummy arm for crutch testing, to complement their existing test capabilities. Background: A large number of people need crutches on a daily basis. For them it is essential that their crutches do not fail. ISO (the International Organization for Standardization) conducts ongoing work to guarantee the durability and function of e.g. crutches.

This work deals with mathematics teaching in preschool classes. The purpose of my study is to investigate the preschool classes? teachers' aspirations for the children learning mathematics in two different preschools. To achieve my goal, I formulated the following questions to be explored and answered through interviews with five teachers.  Does mathematics in preschool classes have a prominent role in educators' planning? What perception do the educators in the field have about the learning and teaching of mathematics in the preschool classes? How do the teachers understand their own work with mathematics in preschool classes in relation to multilingual students?                                A qualitative interview method was applied.

This study examines how a couple of Swedish daily newspapers construct the hacker network Anonymous, with an aim to discuss its possible effects. The question was: In which ways is the network Anonymous constructed in a few Swedish newspapers?                      26 articles from four chosen newspaper were analysed, but because of many similarities in content, only 10 were chosen for deep analysis. With Fairclough's model of critical discourse analysis as chosen method, constructions varying from the images of heroes to villains were found as a result. The most common construction was that of Anonymous as a threat, which was most often exaggerated compared to what actions were actually described in the texts.

This study investigates how social interaction affects newly arrived pupils? views on their study situation in the Swedish educational system. The aim is to give a contribution to the discussion on the notion of including ?the Other? in educational practice in multicultural schools. Semi-structured group interviews were conducted to explore how the intercultural perspective and the theory of inclusion can be used to explain the dynamics of social interaction.

New national curriculums are issued in order to change the present state of the educational system in a nation. In 2011 the old curriculum, the Läroplanen för de frivilliga skolformerna (LPF94) was replaced by the Läroplan, examensmål och gymnasiegemensamma ämnen för gymnasieskola 2011 (GY11). As future teachers we are interested in how a new curriculum affects the work of teachers concerning planning, teaching and examination from the teacher?s point of view.We conducted interviews with five teachers working at upper secondary schools (16-19 year olds) in Kalmar county. Our theoretical framework is based on curriculum theory and concepts of Leonard Bernstein: framing and classification.
