Test bench for air bearingsThis thesis work consisted of bringing forward and defining the test parameters relevant for a test bench and constructing a test bench that can test and verify the largest existing air bearings that are of use in Micronic Laser Systems AB machines. Because the knowledge about air bearings is limited it is thought that with the help of the test bench the knowledge would increase and in that way improve the air bearings.After learning more about air bearings and their purpose at Micronic Laser Systems AB, I started the concept phase for the test bench. For each part in the test bench I consulted my two tutors, Torbjörn Hedevärn and Johan Bergqvist, at Micronic Laser Systems AB. The final concepts where documented as 3D-modells in Solidworks and some of them have been tested in Solidworks FEM-program.The test bench is designed so that, with the help of a pneumatic cylinder, 25 kilo weights are placed on the air bearing to test its stiffness, damping and the pressure performance under its surface area. To test these parameters the test bench has to have a pressure meter, accelerometer and a microcator.
Vilka faktorer påverkar beslut om förtida projektavslut? : En fallstudie av utvecklingsprojekt hos svenska industriföretag
Today many industrial companies invest a lot of resources on research and development to resist the tough competition on the global market. This leads to a high risk game when the companies start many development projects, with uncertain outcome where some of the projects have to be terminated prematurely. The main purpose with this study is to identify factors, both internal and external, that influence the decision to terminate projects prematurely in Swedish development projects. Factors mentioned in the literature will be compared with case studies on three Swedish industrial companies to demonstrate the most important ones when taking such decisions. First a literature study was made to identify basic terms, a general project model and factors affecting the decision.

Since the 9/11-attacks several nations have been confronted with a new international threat, its nature traces back to the political- and religious- radical movements of the 20th century Cold War. Ever since, various states have been under threat by terrorist organizations around the world due to mainly participating in worldwide counter-terrorist interventions created by western alliances. In Sweden, amongst other countries, the state took security-precautions that would imply total control of information throughout the territorial borders. The assigned proposition was accepted by the Swedish parliament in June 18th 2008, after this date wild spread criticism was still in effect ever since the Swedish government first publicly announced the proposition in May 8th 2007. This study emphasizes on understanding why the Swedish government chose to present this proposition to parliament, in order to complete this task the study will present the motives and the alleged threats that were the core of the proposition and its value-maximizing goal of creating a new surface for Swedish homeland security.
?Var är den goda glassen?? : En studie av föräldrar till barn med neuropsykiatriska diagnoser och deras upplevelse av samhällsstödi biografier
AbstractThe aim of this qualitative study was to investigate how parents of children diagnosed with Autism, Aspergers Syndrome or ADHD/ADD describe their experience of the Swedish welfare support system in written biographies. To answer this question a study of five biographies written by parents with children diagnosed with ADHD, Autism and Asperger Syndrome where made. The conclusion was that the social network itself is of great importance to the parents. Families with single parents experienced a less positive experience of the Swedish welfare support system than parents with a spouse. The study also reveiled that families with a supporting social network and a solid financial ground in combination had the best experience of the Swedish social welfare support system.

Demokratins gränser. Ett liberalt alternativ till påverkanprincipen
What every theory of democracy has in common is a reference to ?a people? who are, in one way or another, collectively self-governing. Given that, surprisingly little attention has been paid to the so called boundary problem of democratic theory, or, in other words, the question of who should be included in the democratic community. Lately, the historically given boundaries have been questioned in favour of a cosmopolitan democracy. Still, little has been said about the boundary problem in general, especially from a theoretical point of view.
Verksamhetsstyrning i grundskolan - En väg till goda förutsättningar för inlärning
This study investigates how performance management in primary schools can facilitate learning, relating to theories of efficient schools. This is done through a qualitative study of the performance management systems in two public primary schools in Sweden. The schools selected were similar in all major aspects, except pupil grades, where there was a clear difference between the schools. The analysis revealed differences in how the schools handled the process of management by objectives, the professional development of teachers as well as routines, rules, and policies. We conclude that having a rooted process for management by objectives, professional development of teachers, and clearly formalized values, gives a school a good foundation to support a pupil's learning and development..
Det publika samtalet som curatorisk praktik
The focus of this study is on the nature of social support from the rape survivor's perspective. Research has shown that social support is essential to the survivor's ability to recover from rape and that it acts as a powerful tool for the survivor to effectively deal with the PTSD symptoms that follow rape. The research also shows that survivors often receive or interpret reactions after a rape as negative. Hence, these reactions can be detrimental tothe healing process.Qualitative interviews with six women on their experience of social support after rape form the base of this study and Anthony Giddens terms ontological security, fateful moments and bodily self-management are a part of the analytical apparatus. Rape is commonly analyzed from a feminist perspective.
Riskkapitalbolags påverkan på styrning i sina portföljbolag: En studie om utveckling av styrsystem i svenska Venture Capital finansierade företag.
The aim of this study is to investigate which management control mechanisms evolve in companies that receive funding from Venture Capital companies and why the management control systems evolve in the way that they do. A case study was performed on three Swedish high technology companies, that all received funding from Venture Capital companies for the first time in 2006. Merchant?s framework, defining all management control mechanisms as either, results control, action control or personnel control, was used to structure the study. Results show that the companies that received Venture Capital all increased the use of management control mechanisms within results control, action control and personnel control.
Var är biblioteket? En användarstudie om distansstudenters biblioteksbehov
The aim of this Master's thesis is to investigate the library needs of distance students. This user study has a student perspective and concentrates on the main question of which way library needs might be expressed by distance students. Associated topics addressed by this study include; the problem of learning centres lacking their own library support, how distance students look upon library support as a concept and whether distance students prefer public libraries or university libraries, and why they make this choice. These questions may give the answer to how distance students deal with information literacy. Theories chosen by the study are in the fields of pedagogical and library science, the social cultural theory by Roger Säljö and in Tom Wilson's theories on user studies and information needs.
En studie ur lärarens perspektiv kring lässvaga elever i samband med textuppgifter i matematik
The purpose of this study was to, from the teacher's point of view; discover pupils with reading difficulties in connection with text assignments in mathematics, the teacher's support for these students, if difficulties coincide and whether it's the mathematics teacher's responsibility to make sure pupils with reading difficulties develop their reading ability. The study is based on a qualitative method and five semistructured interviews with mathematics teachers and one language support teacher.The result shows there is a strong connection between the pupils' reading ability and their ability to manage text assignments in mathematics. A weak reading ability affects the pupil in a negative way when solving text assignments in mathematics due to wrong reading technique if the teacher is absent. It is not unusual that reading difficulties and mathematics difficulties coincide. The teacher's most important role in the learning process is to teach the pupils understanding about the reading technique in different ways and to give the pupils opportunity to get spoken texts.
Utnyttjar konsumenter möjligheten att agera rationellt? : En uppsats om konsumenters sökbeteende inför ett köp med avseende på irrationella köpbeslut eller möjliggörandet av rationella köpbeslut genom informationssökningsprocessen
The buying decision process describes how the consumer makes a purchase decision through a rational process (Markin, 1979) and an understanding for how consumers make a purchase decision can according to Sands et al. (2010) be obtained by increased knowledge for the information search process (the second part of the buying decision process) before a purchase. Today?s society offers great opportunity to obtain information (Rahim & Clemens, 2012; Bawden & Robinson, 2009) and by that there are in other words good opportunities for a rational acting by the consumers. However, there are factors working against that consumers act rationally and seek information prior to their purchases primarily in the form of the concept of information overload (Bawden & Robinson, 2009) which claims that consumers are limited in their information search because there is too much information but also other factors such as lack of time (Wood & Neal, 2009) and ability to find information (Slegers et al.

PLM-SYSTEM FÖR TILLVERKANDE MINDRE FÖRETAG : EN STUDIE OM LÄMPLIGHETEN AV PLM-SYSTEM OCH FÖRANKRING GENOM CHANGE MANAGEMENT
This study aims to investigate how small scale manufacturing companies reason around an implementation of a PLM-system, as well as the suitability of these systems compared to larger companies. The study is built on a qualitative method. Initially, secondary data was gathered through books, articles and reports. Primary data was gathered through four interviews. Two interviews were performed with PLM resellers, one interview was performed with a PLM developer, and one interview was performed with a small scale manufacturing company that opted to not implement a PLM-system.The results imply that overall differences between larger and smaller companies exist in regard to the need of PLM systems.
