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.

AbstractAim: The aim of this study was to investigate if treatment with ?dry needling? in myofascial triggerpoints (MTrPs) in the rotatorcuff muscles may affect impingement symptoms such as pain during provocative tests, shoulder mobility, and function. The research questions were: Does the value of pain change on the Visual Analog Pain Scale (VAS) between before and after treatment? Do the positive provocative tests for impingement change between before and after treatment? Does the active shoulder mobility change between before and after treatment? Does the self-rated function change between before and after treatment?Method: The study was a prospective randomized intervention study and 19 persons with impingement symptoms (mean ± standard deviation; 58 ± 18 years, and shoulder pain duration 3.9 ± 1.6 months) were randomized into two groups. The groups were tested before, directly after and 3 weeks after treatment.

At the Congress of the Swedish Trade Union Confederation (LO) in 1991 a decision was made to reform LOs politics of gender. In the new resolution class and gender were established as equal causes of oppression. This was a giant leap from LOs traditional politics, where the dimension of class had always been considered more important than gender. The present thesis discusses how gender was constructed in LOs discourse after 1990 by analysing their official publications about gender politics called Klass och kön. The key terms in the analysis are continuity and change.

The purpose with this essay is to find out which demands the syllabus for the Swedish language make on the pupils in compulsory school compared to some active teachers? point of view. The method I have used to find out is a qualitative interview, where I have interviewed four Swedish teachers of various professional experiences.After the change of government in 1991, the new curriculum committee had a mission where the goal was to develop the best school in Europe. A national target was introduced and the goals were proposed to be of two kinds; goals to strive for and goals to achieve. A problem in this is that the knowledge that pupils in ninth grade will acquire, is formulated in such a manner so that not even experts in each subject would live up to the demands placed on the students.

To complete an overweight treatment program is associated with better weight loss. Previous studies have in principle focused on drop-out from the entire program, not individual parts of a program. Factors previously shown to influence the patients´ weight loss results are: frequency of individual meetings with a professional, the lack of social support from family or friends, the lack of motivation and in a few studies vacations. In several studies the drop-out patients have stated that their reasons for drop-out were dissatisfaction with the staff and the program design. Drop-out has also been shown to be connected with difficulties in adherence to the diet.

This is a study of the way power relationships change when women start to play candombe in Montevideo, Uruguay. Candombe is a type of music, which is traditionally played by men within the black minority in the country. This study has been done with an intersectional point of view, taking the social categories gender, class and ethnicity in account. The method used was participatory observation in a field study made in Montevideo between November 2008 and February 2009.This study?s main conclusions are that the power relationships change with the participation of women in candombe in several important ways: The women legitimize an alternative way to be a woman when they take the men?s role as a drum player.

This is a case study which investigated the perceived consequences of the organizational change that was implemented in January 2013 at Karlstad University. The study aimed to explore the experiences of the employees concerning the changes in organizational structure and internal communication. This was done through a set of eight individual standardized qualitative interviews with members from different departments. A lot of effort and thought was given to the ethical implications and to create a comfortable and open climate during the actual interviews to ensure that the respondents felt free to speak openly and honestly about their personal opinions and experiences.It is evident that the overall vision was ambitious; aiming to create a more effective organization through cutting off excessive administrative personnel and streamlining decision paths. However according to the opinions of the respondents it was clear that the result was far from the desired goal.

The purpose of this study is to examine whether religious behavior or religious identity changes when a person with Muslim background moves to a Christian country and also very secular such as Sweden. I have interviewed five people with Muslim background that have moved from Turkey to Sweden. In this study I have applied Anthony Giddens and Thomas Ziehe's theories about building up an identity but also Nader Ahmadis theory of migration and identity.The results of this study show that there is a change in the practice of religion but also that this differs between these five people who came from the same country. Nevertheless, a change in the practice of religion can on one hand be as a result of modernity and on the other hand, exclusion of family. It also proves that it is not possible to draw general conclusions on this issue instead it should be looked at from an individual perspective..

This thesis focuses on how companies in the textile and clothing industry view or interpret the idea of corporate social responsibility. The purpose of the study is to create an understanding for how this view affects the dissemination and the implementation of the idea in the organization and what might be the effects on the organization of those processes. In order to identify any differences in how the view affected the processes I have studied the current discourse on CSR simultaneously with my theory and conducted a comparative case study of two Swedish clothing brands. The theory focuses on the diffusion of ideas and change management within organizations. My data shows that the two companies have different ways of interpreting CSR and that this indeed affects their dissemination of the idea in the organization.

Poland has since 2021 dealt with the migration crisis at its border with Belarus and when the new government took power in 2023, many had high hopes for its management of the crisis. But the government has opposed the EU's migration policy and continues the strict migration policies of the last government, which earlier studies have theorized, if it?s sign of a securitization of EU?s own migration policies. This essay examines the experiences of activists who work at the border, by performing interviews and a thematic analysis regarding the Polish state?s handling of the migration crisis with the change of government in 2023 and how they see that it has affected Poland and EU?s relationship.

The main purpose of this essay is to look closer at how and when the Swedish women?s organization Grupp 8 changed their initial socialistic ideological approach and turned it into a feministic one during 1971 to 1979. By 1979 the group was referring to them self as a feministic movement. This is done by analyzing the way Grupp 8: s discussion in the areas of women in relation to work, family and society changes. The primary information is represented by the groups own magazine Kvinnobulletinen.

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

The aim of this project is to find a concept solution for a wireless transmitting system, installed to transmit data from a hydrophone of the ocean floor down by a wave power generator to the office on shore. The project is a literature review in which previous observations and tests are analyzed and put together to find a solution. The result was a comprehensive solution that includes an acoustic modem to transfer captured information from the bottom to the surface, wirelessly through the water. The information is then sent fron the surface on radio waves through the GSM network to the office on land. Between under and over water there are components to convert information between acoustic waves and radio waves, but also various types of modulation, such as amplitude and frequency modulation is required..
