The effects of social media usage in a professional context, specifically the effects on social media usage in relation to leadership have been studied in order to determine weather or not usage can be productive for leadership in general. The study concludes that there are several benefits as well as drawbacks to leadership in using social media, but has yet to conclude weather productive or not. This study gives an overview of a relatively unexplored subject.Leadership in terms of leader, communication and group dynamics have been defined and explained in accordance with existing literature. A  brief review of computer and Internet history attempts to explain the formation and evolution of social media. Risks in terms of risks related to leadership and risks related to IT-security are taken into consideration and have been briefly explained.

The Swedish National Rail Administration has changed in the past decade, from its origin after a less dramatic separation from the Swedish State Railways to becoming an authority with its own identity. Today the National Rail Administration is a large organisation with several different departments, each with its own unique function. To operate train services the railway needs to be ?in shape?, leading to a need for maintenance, reinvestments and new investments. For this purpose, the National Rail Administration carries out public procurement where contractors, who are able to perform maintenance and new construction, submit tenders.

In 1998 the Swedish Socialist Government initiated a project in order to promote economic growth and to end the discriminating social and ethnic segregation in the greater city regions of Stockholm, Gothenburg and Malmo. One of the goals of the project was and still is to promote political participation in 24 of the poorest areas of the three cities. In a quantitative analysis I evaluate whether or not the project so far has been successful in promoting a specific part of political participation, i.e. electoral participation in communal elections. The results of the 24 poor city areas are compared with a group of 14 likewise poor city areas of major swedish cities.According to my hypothesis, general improvements of the socio-economic status of poor city areas ought to generate positive effects on electoral participation in communal elections.

This thesis studies private equity firms' implementation of management control systems in their portfolio companies and whether the systems are affected by cross-national differences. A comparative case study examines five different private equity firms to derive if there are any differences between the private equity firms' management control systems in the United States, Europe and China. The empirical observations are categorized according to the framework developed by Merchant (1985) and further developed by Merchant and Van der Stede (2003). Theory on the effect of multinationality on management control systems, also developed by Merchant and Van der Stede (2003), are used to explain possible findings. The applied theory includes the cultural dimensions developed by Hofstede (1984) and Hofstede and Bond (1988).

The purpose with this paper is to examine if tertiary education and democracy have an impact on economic growth. In order to decide how democratic the examined countries are the democracy index constructed by The Economist is used. Besides the two central theories the purpose is also to explain why these variables could affect growth and to examine direct and indirect effects. Indirect effects mean that one variable affects another variable which thereafter has an impact on economic growth.34 OECD countries are compared in order to investigate whether education and democracy are strongly correlated with BNP per capita. Therefore a statistical design is used as method.The empirical results suggest that there is significant correlation between democracy and economic growth.

When being in preschool, I have come across children who I have had difficulties to really meet, and I have felt that the communication between me and the child has been deficient. Since I believe that the meeting of child and pedagogue is essential to learning and development, I find this an important subject of further study.The purpose of my study is to investigate if, and how, teachers regard a possible connection between language capability and behaviour. Furthermore I investigate how they work with language acquisition and communication, and what argument the pedagogues have for this work.To answer these questions I have interviewed two pedagogues who have great knowledge and experience of this subject, and also have special interest in children?s language and communication.In my literary review I give an account of how language acquisition is described in literature, and then compare it with how language impairment reveals. I also describe earlier research on how to work with language development, and what the national curriculum for preschools (Lpfö 98) say on this topic.The result shows that my informants divide in their view of how to connect language capability to behaviour.

For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

Detta är en komparativ uppsats som beskriver likheter och skillnader mellan Sydafrikas läroplan, Revised National Curriculum Statement for Schools (Grades R-9), Svenska läroplanen Lpo 94 och kursplanen i religion.Hur en läroplan utformas beror mycket på landets historia. Att Sydafrika har haft mycket problem med exempelvis apartheid speglas också i läroplanen. Demokrati är något som tycks vara mycket viktigt för den sydafrikanska skolan. I Sverige har vi haft demokrati relativt länge, och det verkar nästan som att vi börjar ta detta för givet. Hur stort utrymme demokratin tar i läroplanerna och kursplanen i religion är en av sakerna jag tar upp i denna uppsats.Jag jämför också hur man beskriver religionsämnet i respektive läroplan/kursplan.

The intention of this study was to examine the interaction between authorities. More specifically it had a purpose to look at the ongoing cooperation between social workers and staff of special homes of closed institutional youth care. The sanction system for young offenders? reform of 1999 where young people between the ages of 15-17 who have committed serious crimes, can be sentenced to secure institutional treatment instead of prison, aims to counteract the harm which can result from a stay in prison. The social welfare board in the young person´s local authority and the national board of institutional care shall cooperate during the youth?s placement at the special home of closed institutional youth care.

The aim of my study is to investigate if and in that case how the writing process and texts written by students in the upper secondary school are affected by the writing tool; does it matter if they write their texts on a computer or by longhand? Another objective is to compare such an effect with the findings of previous studies performed on earlier generations of writers. The first part of my study was a survey. It showed that two thirds of the 67 students participating thought that they would have written better texts in the national writing test if they had been able to use computers. In the second part of the study each of the fourteen participants wrote one text on computer and another by hand.

The aim of this thesis is to examine how the EU directive 2004/35/EC on environmental liability impacts the Swedish administrative legal order. The thesis examines the directive through two main EU principles - the principle of good administration and the principle of procedural autonomy. The EU principle of good administration as a concept contains various procedural and substantive obligations that make up the subject for examination of the directive, both as regulated in the directive and as general principles of EU law. The directive is analyzed using a comparative method to determine to what extent the procedural and substantive principles of the directive impacts the Swedish administrative law, and weather or not the Swedish regulations comply with the EU principle of good administration.The results of the study shows that, althought there?s a general principle of national procedural autonomy, the EU principles of good administration do affect the Swedish administrative regulation in various aspects, through the implementaion of the directive on environmental liability as well as general principles of EU law.

Today, the management concept of lean has stretched far from its origins in the Japanese automobile industry. When reaching the Swedish restaurant industry, the conditions for a successful implementation of lean change as a result of the high employee turnover and the significant amount of part-time employees characteristic for the industry. Combined with a high-end service profile, these workforce characteristics seem inconsistent with some of the basic principles of lean. By conducting a case study, this thesis aims to investigate the effects of a variable workforce on the enablers for a successful implementation of lean in a high-end service industry. Using a theoretical framework consisting of enablers for an implementation of lean in services, the study finds that the variable workforce inhibits an implementation of lean by complicating the effects of traditional training, as well as the possibility of understanding the lean concept at all levels of the organization.

Today evidence exist that environmental chemicals deteriorate male sperm quality and that testicular cancer is increasing. Bisphenol A (BPA) is a chemical with estrogenic effects used in the manufacture of polycarbonate plastic and are found in, for instance, plastic boxes, feeding bottles and food containers. Much of the research on how men's reproductive ability is influenced are performed on rats. This review article complies how male rat reproduction is affected by BPA as a model for humans. Studies have investigated how sperm are affected, hormonal changes during reproduction and how reactive oxygen species (ROS) affects sperm.

From my own experience as a school counselor I have learned that the decision making processes in terms of supporting and helping the students is extremely hard and very individual. In different situations, a different approach between individuals is present. I thought about which factors effects the school counselor?s way of handling problematic situations. I soon realized that the individual has a great effect on the work itself.

The aim of this thesis is to describe and analyse the ideology behind Sida's cultural aid by using postcolonial theory. We want to analyse the discourse on cultural aid that is found mainly in Sida's publications. The interpretation of the sources is made with a hermeneutic base and by using postcolonial theory in combination with Paul Ricoeur's theories on the function of ideology: 1. ideology as distortion, 2. ideology as legitimation, and 3.
