Sjuksköterskans hantering av daglig stress i arbetet - en litteraturstudie
The aim of this study was to describe how nurses cope with their daily stress at work. A literature review was made to answer the research question, data was gathered from two databases; Academic Search Elite and Medline (via Pubmed). The result which was based on 20 scientific articles showed that nurses used problem-focused and emotional-focused coping strategies to deal with the stress at work. Most of the nurses used emotional-focused coping strategies by practise some kind of physical activities, avoid and take distance from the problem. Using these strategies was negative correlated with burnout and psychological health.
Analysverktyg för webbsidor med JavaScript
New technological innovations like tablets and smartphones have a taken significant market share on the web and puts new demands on webpages, the user interface and compatibility among different client devices. The full test of a web-based system prior to the publication is often regarded as an important part of the process to create a complete and successful website. This bachelor thesis investigates the possibility to analyze mobile-adapted web sites using a system that first records the visitor's activities and then replays them for an expert analyst to provide valuable information to developers about how their site can be improved.The essay begins with a litterature study on today's most common web development tools and then examines the possibility to apply them during the development of the analysis tool. The work also describes two methods, pair programming and waterfall method used during the project. Three different evaluation methods are presented and one of the models is applied on the finished system.The project results in a web-based analysis tool written mainly in JavaScript using the jQuery library.
Lärcentrum i biblioteket, möjligheter och utmaningar. Tre aktörsgruppers syn på lärcentrum och dess samverkan med biblioteket
The aim of this thesis is to investigate the points of view of three groups of actors about their local learning center and its collaboration with the library. By interviewing groups of actors from the municipal sector, the library staff and students, I aim to investigate their associations of the learning centre, what kind of services it should offer, and how they understand the role of the library staff in specific collaboration between the public library and the adult education administration. The study design is based on Gunnar Grepperud?s and Terje Thomsen?s three missions for a local learning centre; the mission of a broker, a meeting place and a motivator. I also use Carol Kuhlthau?s levels of mediation as an approach to investigate how the actors want the library staff to work in relation to the centre.
En undersökning av Bergvik skogs och Skogsstyrelsens gallringsmallar mot en gallringsoptimering på simulerade typbestånd
The purpose of this study was to analyze the two thinning models: Bergvik Skog´s thinning model, which is based on total stems and dominant height, And Swedish forest agency´s thinning model which is based on basal area, habitat index, dominant height and recommended number of stems at final felling in Heureka´s StandWise and PlanWise.
The data we chosen for our study were taken from the Swedish National Forest Inventory and we were creating a simulated stand based on a great number of sample plots in Region three from The Swedish National Forest Inventory. We had chosen to create one stand with low habitat index (T20) and one with high habitat index (T24). Our purpose were to come as close as possible to a natural stand in central Sweden. We performed the thinning in StandWise and analyzed the data I Excel files. Our thinning optimizing´s were performed and analyzed in PlanWise.
There wasn´t any big differences between the thinning on the lower habitat index.

To give good nursing, knowledge has to be gathered of how the child thinks, feels and what the child wants. Aim: The aim of this study was to describe children?s experience of hospitalization on the basis of the four nursing concepts person, health, environment and nursing.
Modellering och simulering av det evaporativa bränslesystemet i en personbil
This thesis work has been performed at the department of diagnosis and dependability at Volvo Car Company, Torslanda. The background of this project is based on interest in ascertaining how different factors possibly can affect a diagnosis method, which has been developed to find leaks in the fuel tank and evaporation system. According to the OBD II requirements leaks with an orifice diameter larger or equal to 0,5 mm, must be detected. The idea of the diagnosis method is to create an over pressure in the system with an air-pump. The current through the pump is measured and correlates to the power consumed by the pump.
?Man måste vara macho, därför att mesen inte går hem? : En kvalitativ studie om kvinnors våld mot män i heterosexuella förhållanden sett ur myndigheter och ideella organisationers perspektiv.
The intention of this qualitative study is to describe and analyse women's violence against men from the perspective of authorities and volunteer organisations. Data has been collected trough semi-structured interviews with six respondents stemming from the police, social services and a help organisation for men respectively. The data has been analysed using existing research and common theories about power, sex and gender. The study shows that IPV does not only contain physical violence, but also acts of psychological-, sexual-, economical-, material-, and latent violence as well as the fact that one act of violence almost never exists alone. It is shown that women more often use psychological abuse against their partner then men do and also that men tend to stay longer in an abusive relationship then women.
Simulering av simulinkmodeller med Extended Kalman Filter
Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical user interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.

Förslag på riskklassificeringsmodell av ekologiskt kontrollerade aktörer : En jämförelse med andra länders ekologiska kontroll
In order to facilitate trade between EU members, the European Committee has created regulations that will govern supervision of organic products. Every regulatory agency shall, according to the European Committees regulations, carry out a risk classification of each organic producer they regulate. This study for The National Food Administration compares regulation of Swedish organic products with other countries, and aims to produce a simplified model based on risk that can be the beginning of the risk classification model that Sweden in the current situation don?t have. The thesis is based on three questions: 1) What criteria should we use for assigning organic food producers? 2) How do selected European countries and frontrunners rate organic producers and what can Sweden learn from them? 3) How might a national classification model of organic production look in order to ensure an equivalent level of regulation and prevent competition among private inspection bodies? A review of information gathered from the different countries gave differing results.
Elevers uppfattningar av vad man bör uppnå efter avslutad kurs i Idrott och Hälsa A : En studie av två gymnasieskolor i årskurs 2 ? ett elevperspektiv

Klimatet på tre platser i Sverige 2071-2100 i jämförelse med Europas klimat 1961-1990 med fokus på temperatur, nederbörd och avdunstning : En analytisk studie från en simulering av Rossby Centres regionala klimatmodell, rca3.
Due to human influences on the climate an increase in Earth's mean temperature is today an accepted conception. With a rising temperature discussions have started how the climate in an area will change in the future. Equally interesting and important is it also to study the precipitation in an area. Precipitation is the factor, next to temperature, that affects most how a climate in an area looks like and feels. Since precipitation is connected to evaporation the latter parameter is also of interest to study.
