Slaget om kärleken: En fallstudie om den svenska marknaden för nätdejting, dess nuvarande tillstånd och framtida utmaningar
Internet dating is a relatively new phenomenon that, in using the opportunities of the internet, has taken traditional dating to a new level. The business idea is simple as such. The company provides its customers with a platform that enables interaction, leaving the value creation to the customers. A qualitative study is conducted investigating and mapping the Swedish market for Internet dating. It is researched what the characteristics of the companies are, what the Internet dating businesses in Sweden offer, what the prevailing market conditions are, and lastly what challenges lie ahead for the industry and how they can be solved.
Tillämpning av en markprofilmodell för hydrologiska beräkningar i avrinningsområdesskala
There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..
Södra Lapplands Kommun? Vad för effekt skulle en sammanslagning av Åsele, Dorotea och Vilhelmina kommun få på den lokala demokratin?
In 1974 the three municipalities of Åsele, Dorotea and Fredrika were amalgamated despite of hunger strikes, mass protests and a serious threat of violence. But after six years the marriage shattered as Dorotea left the other two after years of continued struggle. In 2005 the idea of an amalgamation of Åsele, Dorotea and Vilhelmina municipalities was brought to life by an older and ever declining population.By creating a democratic ideal type consisting of the three variables ? legitimacy, participation and identity ? this study assesses what impact an amalgamation of the three municipalities might have on local democracy.Combining a qualitative and a quantitative approach this study concludes that amalgamating the municipalities today could create a democratic unit lacking legitimacy, having a weak identity and impeding participation. But the study also brings forth that the impact of an amalgamation upon the variables of the ideal type as defined is not written in stone.
PÅVERKAS DEN KOMMUNALA SKATTESATSEN AV POLITISKTSTYRE? : En strukturell analys av faktorer som avgör skatten i svenska kommuner
The aim of this report was to investigate which factors determine municipal taxes in Sweden.The aim was also to find out whether and how the forms of political rule are significant covariates. A multiple regression analysis was performed using data from 289 municipalities. The analysis resulted in five dierent models, of which a model based on municipal grouping was found to be most satisfactory. In all of the models, there are effects from the form of political rule. The results indicate that socialist municipalities have higher tax rates than non-socialist.
Dimensionering av betongplatta på lös undergrund. En jämförelse mellan tre beräkningsprogram
Today more effective computer programs are in use, regarding design of geotechnicalconstructions. There is a risk that the theoretical background of the computerprograms, its limitations and the signification of the choice of soil parameter isforgotten when the computer programs become more user-friendly.This Master thesis deals with simulation and analysis regarding three computerprograms, FEM-design, with the addition Raft, Plaxis and BE-slab. Comparisons aremade for settlement and maximum moment in a concrete-plate. FEM-design is a threedimensional FEM-program, foremost created for design engineers. Plaxis is a twodimensional FEM-program, intended for geotechnical engineers while BE-Slab is aBoundary elements program in two dimensions that is mainly used by designengineers.
Patienters upplevelser av livsstilsförändringar vid diabetes typ 2 : en systematisk litteraturstudie
Diabetes type 2 is a fast growing illness and a global health problem, often a result from less appropriate standard of living. Lifestyle changes related to diet and physical activity are important lifestyle changes regarding to get control of the self-management and to avoid vascular complications.AimThe aim of this study was to describe patient's experiences of lifestyle changes in diabetes type 2.MethodA literature study was carried through based on 12 qualitative scientific articles.ResultsThe analysis result into two main themes and eight subthemes. Main themes where barriers and motivators for lifestyle changes and the subthemes where struggle, denial, lack of knowledge, alienation, support, motivation, acceptance and knowledge.ConclusionThis study shows that lifestyle changes are experienced different by patient with diabetes and nurses should therefore be aware of the unique and specific demands these patients require. This is important for providing a good diabetic healthcare and to help patients with their self-management.
Hur livet påverkas : En kvalitativ intervjustudie om äldres upplevelser av att leva med typ 2-diabetes

A lifestyle change is a major part of the treatment for type 2 diabetes. There are several factors that suggest positive effects on prevention among the elderly where, among other things, economic and health benefits are presented.
Higgsbosonen, standardmodellen och LHC
This report aims to provide an insight into the particle physics of today, and into the research that goes on within the field. The focus is partly on the recent discovery of the Higgs boson, and partly on how software can be used to simulate processes in particle accelerators. Basic concepts of particle physics and the search for the Higgs boson are discussed, and experimental results, including those from the Large Hadron Collider, are compared with simulations made in MadGraph 5. Furthermore, simple new models of particle physics are created in FeynRules, in order to make simulations based on the models. To support the presentations of these aspects, some of the underlying theory is built from the ground up.

Sakprosans genrer: en analys av fyra universella klassifikationssystem
The aim of this paper is to investigate the implementation of genres, pertaining to non-fiction, in four different universal classification schemes BC2, UDC, DDC, SAB. It is not the aim of this paper to answer the question why certain genres are more implemented than others, or vice versa. Instead it is intended to be an investigation into the concept of non-fiction genres with the aim of attracting attention to the many interesting aspects of this concept for library- and information science research. An analysis of the schemes general auxiliary tables is performed by comparison with a specific genre-system devised by Ottar Grepstad. This genre-system is organised by dividing different genres into groups according to linguistic criteria.
Att leva med diabetes typ 2 - en livslång utmaning : En litteraturöversikt
Background: Type 2 diabetes is a chronic disease that vigorously increases worldwide. The disease can affect the entire everyday life which usually results in major lifestyle change. The treatment consists largely of self care which the patient itself has great responsibility for. The nurses have an important role in supporting, guiding and teaching the patients. Since every patient is unique the nurse would benefit from an increased knowledge about the patients experiences of what promotes and prevents self care in type 2 diabetes. Aim: The aim was, from a patient perspective, describe the experience of what promotes and prevents a self care in type 2 diabetes. Methods: A literature review based on nine scientific articles gathered from the databases CINAHL plus with full text, PubMed and Medline.
Produktivitetseffekter av flerträdshantering
The main purpose of this study is to investigate the productivity effects of multiple tree handling in thinnings. Other important elements have been to investigate in which extent multi-tree handling is used in stands with different stem volumes and the impact of collecting partially delimbed fuelwood assortments has on harvesting performance.
The study is based on data from thinnings in Sydved and contractors' operating activities. Collection and compilation of operating schedules, number of stems and surveyed volumes from several contractors and a large number of executed orders underlying the results.
Multiple tree handling is used to a much greater extent at lower average stem volumes. Prediction models for productivity of the multiple-tree handling harvesters in the study differ from the productivity models for single-tree handling. In the model developed in this study productivity is not as dependent of stem volume as reference models.

Chapter 3 is devoted to the Boolean model, Chapter4 to the fuzzy model and Chapter 5 to the Van Rijsbergen model.These three chapters are organized in the same way. First, the logical foundation of the modelis given.
Nätverksdemokrati -vad bör, är, kan den vara
The main objective of the essay is to define the meaning of the termgovernance network on the basis of democratic values ? both normative andimperial - with the aim to analyse the prospects to develop an effective anddemocratic governance. Democratic values as well as civil participation,enlightenment, responsibility and approachability are discussed, but also moreeffectivness orientated values.It is clear from the presentation how normative and democracy models putdifferent values in focus, with the consequence that other values are played downor pushed aside. Compared to imperial research in partnership ? by definition atype of network arrangement - and with a starting point in democracy andefficiency, the networks are discussed as political formation.In what sense can the actual existing network arrangements meet and fulfil thedefined political values? As no straight forward answer exists, there is an ongoingconflict between the political demand for slowness and the effectiveness demandfor flexibility and mobility..
Diabetes Mellitus typ 1: Sjuksköterskans erfarenheter i arbetet med ungdomar : En litteraturstudie
Abstract Background: Type 1 diabetes is a chronic disease that worldwide greatly increases among children and adolescents. Major demands are required from the individual who has this disease, which also requires significant knowledge from the nurses so they can be able to develop and create individual conditions for children and adolescents. Thus, the children and the adolescents can be able to take responsibility and feel secure in their own care. The nurse's techniques and specific tools in this work are however not particularly noteworthy and therefore needs to be advised.Aim: The aim of this study was to describe the experiences nurses have of supporting adolescents, between 12-18 years, with type 1 diabetes to an increased understanding of the disease and also to examine the methodological aspect data collection in the articles of this study. Method: A descriptive, literature study according to Polit and Beck (2012).
