In your Face(book) users! En studie om socialt login och människans strävan efter konsistens
Concern about personal privacy continues to grow among online users along with the fact that new technologies help online companies to share user's private information. Still the usage of online entities such as social networks and e-commerce sites continue to increase. This raises the question of why online users act in such a contradictory and irrational way.Our study examines what impact one recently developed application called social login, which is provided by several social networks and used by millions of online companies, has on consumer's evaluation of online brands when they are primed for various types of information concerning privacy issues. Our assumptions are built up on the theory of cognitive, dissonance and suggest that there will be no differences in evaluation of the brands due to the human need to rationalize their existing behavior and attitudes when they receive new or contradicting information. The potential effects are measured by a manipulation presented in a survey distributed in an online environment to a sample of users (n=,154).
"Säg mig vad du äter och jag ska säga vem du är" : En kvantitativ studie om efterfrågan av hälsosamma livsmedel
Obesity and overweight are today classified as one of the largest epidemics in the Western world and is threaten a large part of the population. As a reaction to this a major health trend has emerged in recent decades. Every day consumers are exposed to information from the media about what is healthy or unhealthy to eat and the recommendations change frequently.There is great interest in healthy food on the Swedish food market, but still healthy foods only represents a small proportion of the total food sales. The essay examines the gap between the current and potential demand for healthy food and if it can be explained by any of the following factors: lack of information, price, taste or cognitive behavioral.To study these questions a quantitative method have been used and 213 questionnaires were collected. The intention is to draw general conclusions about the entire population.
Tre studenter med ADHD berättar om upplevelsen av att läsa i högre utbildning
Research shows that there is a lack of knowledge of adult students with ADHD.
Most of all research focuses on children with ADHD in school. The purpose of
this study was to gain a better understanding of how adult learners with ADHD
experience academic studies related to cognitive difficulties, emotion,
motivation, and their experience of SOC. The questions tried to determine how
any cognitive difficulties and emotions are perceived, how students' motivation
to study impacted and their experience of SOC based on studies in higher
education. To answer the purpose and questions used qualitative interviews
based on three students with ADHD using a hermeneutic method.

Undersökning av elkvalitet i distributionsnät med omfattande vindkraftselproduktion
The goal for this master thesis project has been to investigate the power quality in adistribution grid, which has a high fraction of dispersed power production due towindmills. The study has been done on a grid in Laholm South of Halmstad, whereapproximately 45 windmills are connected to the distribution grid owned by SHKEnergi. The investigation has been focused on to two radialy fed 20 kV lines, wheretwelve windmills are connected.Voltage variations have been studied by creating a model of the grid in the simulationprogram SIMPOW. The largest deviation that has been found in any point of the gridis ±1.9 % of the nominal voltage. This deviation is a result of varying powergeneration from the windmills and the voltage regulation at the connection point ofthe line.
Kinematisk och dynamisk modellering av den haptiska enheten TAU i sex frihetsgrader
The thesis presents an optimally designed kinematic structure for a new 6-DOF haptic devicebased on TAU configuration. The configuration of the TAU-2 proposed by Suleman Khan andKjell Andersson [1] was modified and its mobility was verified by using Grübler criterion tohave a 6 DOF. Analytical kinematic models for the inverse and forward kinematics weredeveloped for the haptic TAU configuration to determine a set of optimal design parameters.Kinematic performance indices such as volume of the workspace, kinematic isotropy and payload index, were defined based on the singular values of the Jacobian matrix. The Jacobianmatrix was scaled to homogenize the physical units. The Jacobian matrix dependent on theposition and orientation of the end-effector gives local isotropy and pay load index, so globaldesign indices were defined, which represent the performance of the mechanism in the wholeworkspace.
Informationssökning och lärare: En studie av 4-9-lärare i övergången från utbildning till yrkespraktik
The main purpose of this Masters thesis is to contribute to the understanding of high school teachers information seeking behaviour in the transition from university studies to occupational practice. The theoretical framework encompasses theories of professional socialization, the sociology of knowledge, of professions, and of library and information science. The empirical material has been collected through interviews with six recently qualified high school teachers in different subjects. The interviews have been analysed on two different levels; first on a descriptive level and then on a theoretical level. The major findings are that the academic context limited the student teachers information seeking and they did not have the opportunity to choose cognitive authorities on their own initiative.
End of line test : En studie av företaget Emotrons linjetestning i produktionen
Emotron is a company specialised in developing, producing and marketing equipment to con-trol, monitor and protect processes and machinery driven by electric motors, with an applica-tion focus. Examples of uses for their products are fans, pumps, lifts and cranes.The project is to look at Emotrons end of line test. The company has seen that at the final test-ing there is a bottleneck that restricts the outflow and prevents an increase in the number of tested products.The purpose of this project is to review how Emotrons end-of-line test works today and if there is a possibility to make the test more efficient in such a way that the quality is not at risk, while increasing the outflow of tested products.The projects first step is to look at and analyse what is causing the bottleneck at the end-of-line. When the analysis is complete, the next step is to review whether there is a possibility to solve the bottleneck and if so in what way can this be done. Emotrons most overall objective of the project is to increase the outflow of the number of tested products without jeopardizing the quality.An analysis has been made on frequency inverters, soft starters and shaft power monitors.
Patienters upplevelse av Basal Kroppskännedom efter avslutad behandling : En kvalitativ intervjustudie speglad ur socialkognitiv teori
Introduction: Basic Body Awereness Therapy (BBAT) is a treatment developed to treat different kinds of psychiatric diagnoses, but also to prevent the emergence of any other unhealthy conditions. The treatment is aimed to increase the body control and conscious breathing but also requires mental awareness.Aim: The aim of this study is to, based on social cognitive theory, describe patients' experiences of BBAT performed as group therapy.Method: The study design was qualitative with an inductive approach. Five people were interviewed after a BBAT group treatment in primary care. The data was collected by individual interviews with semi-structured questions and the interviews were analysed by qualitative content analysis.Result/Conclusion: The participants experienced increased body awareness and implemented BBAT strategies even though the treatment frequency was insufficient. BBAT was described as helpful used to regulate intensity level, stress management and facilitate breathing.
Välbefinnande och Kognitiv Prestation : En experimentell studie om positiv sinnesstämning främjar kreativitet och flexibelt tänkande
The purpose of the study was to investigate, through an experiment, if positive mood promotes creativity and flexible thinking. Participants were a total of 93 college students. The main hypothesis was that subjects induced with positive mood would perform better than subjects induced with negative mood, at a test reflecting creativity. To further explore the implications of priming (subliminal manipulated moods), a neutral control group was included. The cognitive test used in the study was Duncker´s The Candle Problem, a test which aims to get the subjects to apply flexible and creative thinking.

Nyblivna mödrars erfarenheter av initiering av amning : En jämförelse mellan tre kliniker
ABSTRACTThe aim of this study was to describe various methods of treatment and effects of treatment of ADHD, and to investigate wheater there is an association between adults with ADHD and obesity. Method: Literature review. Twelve quantitative scientific articles were found in the data bases PubMed, Cinahl and MedLine. Result: ADHD is a cognitive impairment that can lead to serious complications such as obesity. Studies show that drug treatments of adults with ADHD have positive effects in terms of reduced symptoms, increased efficiency and improved quality of life, but drugs can also cause side effects in form of loss of appetite and insomnia. For adults with ADHD and obesity drugs that affect metabolism have a significant impact on patients ability to lose weight.
Får högpresterande elever den utmaning de har rätt till i skolan? : En empirisk studie baserat på lärares åsikter om arbetet med individualisering med fokus på högpresterande elever
The purpose of this study is to investigate five teachers? opinions on the work with individualization with focus on above-average pupils. I have issued four questions based on the purpose of this study: - How do these teachers define the theoretical concepts of individualization and above-average pupils? - How do the teachers reason about the concept of individualization with focus on the above-average pupils? - How do the teachers reason regarding the work with individualization in the Swedish language? - Do these teachers consider that there are difficulties to individualize the work so that it will challenge above-average pupils?The method used to conduct this study was a semi-structured qualitative interview with five teachers in primary school. The theory and the theoretical concepts this study is based on is: what defines the above- average pupils, the zone of proximal development, the concept of individualization and motivation and the importance of cognitive and non-cognitive abilities.The study shows that the theoretical concept of above-average pupils is hard to define and it shows a difference between how the teachers choose to define it.
En studie av retentionen i floden Oder och dess avrinningsområden, Polen.
Nutrient enrichment is the main cause of the increasing eutrophication process in the Baltic Sea during last century. A prerequisite counteract this process the load of nutrients to the Sea must be investigated. The large contribution of nutrients to the Sea is caused by emission from the rivers within the drainage basin. For the total emission of nutrient into the Sea the retention process in the rivers has big influence. This process in the river system has been assumed as a not important part of the nutrient cycle.
