En studie om konflikter i arbetslivet och det  systematiska arbetsmiljöarbetets roll som verktyg till förebyggande arbete.

Abstract The main subject of this essay is conflicts at work and the effect it has on the employee´s health.  I can through various reports read that bad health at workplaces is too high and that conflicts are a reason. What can be done to the work environment so it will be better from a psychosocial perspective? Sweden has a regulation that makes the employer responsible to work for an improvement in the work environment; can these regulations be used in purpose to reduce conflicts?My first question concerns the possibility to establish preventive procedures in the workplace systematic work regarding to improve the work environment. My second question is about the obligations of the employer to attempt to reduce conflicts at the workplace and the third question regards the documenting and monitoring of conflicts and the preventing work to reduce them. The purpose of this essay is to clarify how conflict preventive work can be included in the Systematic work environment management.

Utmattning av järnvägsbroar i armerad betong : Enligt eurokoder

Commissioned for this report is Ramboll, Bridge and Tunnel Unit in Stockholm. Theidea throughout the work has been to primarily help bridge designers compilingadvice and instructions on how fatigue verification for railway bridges in reinforcedconcrete shall be performed under the new rules, the Eurocodes.After the introduction of the Eurocodes in 2011 has major problems emerged amongdesigners around Sweden. In some areas, it differs in the calculation rules comparedwith rules from the Swedish Transport Administration and the National Board ofHousing, Building and Planning calculation. Fatigue verification is one area where thenew calculation rules are different from the past.A large part of the report has been to interpret and find the relevant information inthe Eurocodes concerning fatigue. When questions or doubts have surfaced, this hasbeen discussed with Elisabeth Helsing at the Swedish Transport Administration andbridge designers at Ramboll.The result is a report where the structure is organized in the way that the bridgedesigners can move from cover to cover and realize that fatigue verification in realityfollows the same order as the report's sections.

Att kommunicera miljö ?Sällan ett papper på väggen? : En undersökning om kommunikationsstrategier vid implementering av miljömål i två högstadieskolor

AbstractHeadline To communicate the environment, ?Rarely a paper on the wall?, a study about communication strategies when it comes to internalize a policy in two secondary schools.Number of pages 42 (61 including enclosures)Author Fanny PerssonTutor Peder Hård af SegerstadCourse Media and communication CPeriod Autumn 2007/spring 2008University Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/aim The purpose of this work was to see what channels of communication are to prefer when working with secondary school pupils, more concrete when speaking about the environment, about the profile of the school and democracy among the pupils.Material/method I am going to visit two secondary schools in the middle of Sweden, one that has an environment certification, and the other one is a regular secondary school. To answer these questions I am going to interview totally four teachers, two from each school, and 12 pupils from each school divided into two groups per school.Main results One of the main results was that the pupils prefer to mix the tutoring for a better way to learn. Another result was that they see their teachers as paragons and that it is more important what the teachers do than what they say.Keywords Environment, Communication, Environment Certifikation, Secondary school, Karl Weick, Communication theory, Understanding, Internalize, Identification, Profile.

"Vet inte hur man gör om det kommer in en muslim" : En kvalitativ studie om konstruktionen av etnicitet och åldrande inom äldreomsorgen.

The purpose with this study is to examine and analyze the eldercare staffs conceptions and perceptions about the construction of ethnicity and aging, in Swedish eldercare, to illustrate the process of othering. The authors interviewed eight people who work in the eldercare by using a vignette. We have analyzed our result from the interviews through several theories and earlier research pertinent to the subject. The study has shown that eldercare staff through their conceptions and perceptions unconscious been conducive to make and recompose constructions of ethnicity and elder. The constructions of ethnicity and elder can be conductive to processes of othering..

VISUALISERING AV KATALOGHUS -med ADT och VIZ Render

The aim of this final thesis is to make it easier for the customer of a new designed house to get a picture of what the house will look like inside before it has been built.A method, which can be applied by any construction company who likes to visualize there buildings, has been designed and tested. One works after a regular design planning which is transformed into a three dimensional model of the house. In a rendering program, materials and surfaces are chosen for the model and then a picture of the finished product is made. The programs used for this work are ADT 2006 and VIZ Render.To evaluate the use of this method I?ve chosen to cooperate with LB-Hus which is a housing company that is specialized in building detached houses.

The purpose of this study has been to investigate students? perceptions of the content inthe Swedish subject and current syllabus for Swedish in the third year of uppersecondary school. The purpose has also been to analyze if students are familiar with theaims they are working towards, how explicit they are and if they have any significancefor the students? results and motivation. This investigation is based on a socio-culturalperspective and was made with help of a quantitative method by using questionnaires,but has also been studied to some extent qualitatively, which have been analyzed from astudent angle.The analysis of the results shows that the students have very good perception ofwhat they should study in Swedish year three in upper secondary school.

Påverkan av ackulturation på invandrares upplevelse av arbetets mening: en fenomenologisk studie

The purpose of this phenomenological study was to facilitate increased understanding of immigrant's experience of the meaning of work with focus on how that meaning can change as a part of the acculturation process. Participants (n=13) from eight countries answered an open question. The responses were analysed using Meaning Construction Analysis (MCA)-Minerva and the individual's life-worlds were made visible and discussed. The themes meaning of work, work, unemployment, education, adjustment, immigration, Sweden/country of origin, dreams, possibilities and self appeared as jointly shared important aspects. The results indicate that work is of central importance, and although the individuals share certain experiences, the meaning associated with the themes is of a complex and individual nature..

Lagring av kyla med horisontella markvärmeväxlare för kylning av koncepthus i Mellanöstern

Norconsult AB has developed a solarhousing concept, a house designed for the warm climate in the Middle East andwith large quantities of solar panels installed. The cooling system for the house was designed in an earlier report, the purpose of this thesis is to investigate the possibility of short and long term storage of thermal energy via an underground energy storage volume.Two different designs of the storage and three different filling materials have been integrated into a model to simulate different cases. The first design consisted of pipes installed in the ground, without insulation. The second design consisted of an insulated concrete box installed to prevent thermal energy from the surrounding soil to flow towards the lower temperature regions within the storage. The three different filling materials were dry saudi sand, water saturated saudi sand and the filling material used by the client for energy storage in Sweden.The results from the simulations show that neither of the designs, regardless of the filling material, managed to extract enough thermal energy from the house to the ground to uphold the demands of indoor climate.

Konvertering från luft till vätskekylning av elektronik

A Swedish electronics company wants to make the cooling of one of their electronic components more efficient. They propose that a retrofit liquid cooler is the way to achieve this goal. The current air cooling has high energy cost due to the high amount of power needed to power fans and heat exchangers. Using high volumes of air for cooling also leads to noise pollution. The conversion from air to liquid cooling would possibly make the operation of the electronics more cost efficient and less noisy.The purpose of this project is to theoretically evaluate different concepts of drawing the heat generated by the electronic component in to a fluid, using numerical calculations in Matlab and FEM simulations in ANSYS.

Enligt vägledningsteorin Social Cognitive Career Theory, SCCT, gör individer ?karriärval? utifrån sin subjektiva prestationsförmåga, den s.k.?self-efficacy?. Beroende av hur individen uppfattar sin egen förmåga och värderar sig själv, vidgas eller minskas handlingsutrymmet.

A Strategic Decision-Making Model for Supply Chain - A Void to be Filled

Many researchers emphasize the increasing strategic importance of supply chain management, but there is still a lack of concrete guidance for managers faced with strategic decisions in supply chain. Within decision-making theories, the rational decision-making model is the most commonly used. This because of its suitable foundation, enabling a structure to the complex decision process. The rational decision-making model is today not developed to include the aspects of strategic decision-making made in supply chain. The purpose of this research is to adjust a structured rational decision-making model, making it applicable for strategic decision-making in supply chain.

Fyra elevers upplevelser kring grupparbeten

The purpose of this study is to investigate four students in grades six by interviewing them. It will find out how they personally perceive their own learning in group work and why they work in groups. In my investigation, I will rely on these two questions:How do my subjects reflect on their own learning during group work?Why do my subjects think that they work in groups?For my study, I selected four students from the same school, two girls and two boys, who are 11 to 12 years old. The interviews were individual because I wanted to get a deeper view of how students perceive their own learning in groups and why they are working with a group of other students.
