Our purpose was to examine how social workers, within the child- and youth psychiatry, works with aggressive children and which theoretical perspectives they use. The questions we wanted to examine were how they worked with these children, how they motivated their work and which theoretical perspectives they used. The method that was used was a qualitative interview, where six social workers were interviewed. The result showed that their work foremost was based on conversation methods and all social workers emphasized the importance of a near cooperation with the parents since they considered that parents had the strongest influence on the children. Some social workers focused foremost on altering children's aggressive behavior while others focused on understanding the meaning of the behavior.

Virtual Communities is an increasingly common phenomenon on the Internet. Most of the Virtual Communities are operated and maintained on a non-profit basis with a direction towards entertainment. However, as more state administrated and commercial services become web-based, we believe that the number of Virtual Communities with a community-based or commercial direction will increase in a near future. In this thesis, we describe our participation in, and studies of, a number of Virtual Communities with focus on the IRC-channel ?3dfxsweden?. On the basis of our experiences, we describe the social elements that form the foundation on which the Virtual Community rely on.

Bakgrund: Det rådande pensionssystemet i Sverige består av sex så kallade AP-fonder. Genom åren har pensionssystemet flertalet gånger kritiserats för dess låga avkastning.Problem: Vår huvudfråga är att jämföra AP-fondernas risk och avkastning med aktiemarknaden som helhet, detta ska ske med hjälp av två jämförelseindex: MSCI World och SIXRX.Syfte: Syftet med uppsatsen är att jämföra de fyra första AP-fondernas risk och avkastning med aktiemarknaden som helhet under åren 2002-2010.Metod: Vi har använt oss av en kvantitativ metod, genom att samla in information från AP-fondernas årsredovisningar och hemsidor. Vi har samlat in historisk data, som vi sedan har bearbetat och analyserat.Slutsats: De studerade AP-fonderna har presterat sämre än aktiemarknaden..

Syftet med vår uppsats är att undersöka om det finns ett hot för revisorn vid självgranskningen av en apportemission att hamna i en beroendeställning. Samtidigt vill vi undersöka hur revisorns oberoende upplevs och uppfattas i olika situationer vid apportemission, samt om detta kan leda till en exploateringsrisk för nyägare och minoriteten. För att uppnå vårt syfte genomförde vi intervjuer med revisorer, gamla ägare, nya ägare och minoriteter.Ur agentteori härleds våra tre modeller. Vi tittar på revisorn dels som agent åt principalen och dels som en oberoende yrkesutövare. Dessa modeller är: självgranskningshot, nyägarexploateringsrisk och minoritetexploateringsrisk.Empirisk fakta från de tio intervjuerna analyserades och vi fann att det kan finnas en risk för självgranskningshot då revisorn granskar sin egen granskning vid årsbokslutet.

Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.

Syfte: En komparativ studie och beskriva möjligheterna för att skapa en effektiv portfölj av olika aktieportföljer, där det undersöks om faktorerna som företagens omsättningsstorlek, branschen de är aktiva i och valet att ha utländska aktier, har betydelse eller inte för att skapa en effektiv portfölj med hänsyn till dess korrelation, avkastning och risk. Metod: Uppsatsen utgår från en kvantitativ studie, som sträcker sig från april 2008 till april 2010, då historiska aktiekurspriser används för olika sorters uträkningar, som baseras på uppsatsens huvudteorier; CAPM, Sharpekvot och portföljteori. Utgångspunkten är deduktiv, där slutsatserna har dragits från teorierna.       Slutsats: Utifrån uträkningarna, kunde det inte dras generella slutsatser där de undersökta faktorerna inte utmärkte sig i något mönster. Däremot visade sig att det blev högre avkastning till liknande risk eller lägre risk till liknade avkastning när man väljer aktier som är olika varandra, då korrelationen inte samvarierar. Det bästa resultatet är när utländska aktier blandas in i portföljen.    .

The aim of this study is to create a deeper understanding of the disease known as eating disorder. The study is based on four autobiographies written by individuals who themselves have been affected by eating disorders. These stories have been studied using a narrative approach. To achieve the purpose, the study is focused on what participants describe as the factors underlying the onset of the disease, the factors that participants describe maintained their eating disorders, as well as what is described to be the factors responsible for their recovery. By my interpretation of the stories, I have been able to identify common factors that all participants describe to be influential in their disease course.

Bakgrund: Tidigare studier har identifierat flera riskfaktorer, såsom kost, fysisk aktivitet och BMI, gällande kolorektal cancer. Att analysera kost utifrån kostmönster istället för enskilda livsmedel har visat sig vara effektivt för att undersöka risker för kolorektal cancer. Datamaterial samlades in med hjälp av en fall-kontroll studie med 257 fall och 805 kontroller.Syfte: Identifiera faktorer som ger en höjd eller sänkt risk för kolorektal cancer utifrån områdena kost, fysisk aktivitet och BMI.Metod: Faktoranalys användes för att upptäcka kostmönster. Logistisk regression användes för att skatta oddskvoter och 95 % konfidensintervall.Resultat: Tio stycken kostmönster erhölls från faktoranalysen. Kostmönstren ?Läsk, juice och mjölkprodukter? (OR=1,288; ORQ4=2,159), ?Te, men inte kaffe?(OR=1,228; ORQ3=1,891; ORQ4=1,668) och ?Fågel, rött kött och fisk?( ORQ4=1,724) gav alla en ökad risk.

This paper studies the option market?s implied dividend as a predictor of future equity market returns. We introduce this variable in the simple total return framework and discuss some complications of using it as a proxy for the expected dividend. We construct some regressions using the price-dividend ratio and the implied dividend growth, and test them on six years worth of data on the EURO STOXX 50-index. The main result is that implied dividend growth exhibits some forecastability over two-year horizons, but that the dataset is too short to draw any definitive conclusions about long-horizon forecastability.

It appears from today's debate about the quality of social work and addiction treatment that largely focuses on the impact of recent various interventions in the hope of being able to alter social work's role in society and also the organizational structure. The debate points to a part of the 1970s social welfare debate. Today's aspirations to establish an evidence-based practice can hardly be expected to solve the social services basic dilemmas is that it always have to do something, despite the many times you cannot get clear instructions on which funds should be used by law or science. Even if you follow the rules and practices based on scientific studies should the importance of various key initiatives to remedy deficiencies in social service work with addicts in large part depend on how, in these initiatives define the term "evidence-based practice" and what steps will be indicated for to develop practice. My starting point was to explore how evidence-based social work in connection with medication-assisted treatment for opiate addiction look, which evidence-based interventions Social Services currently uses in connection with medication-assisted treatment for opiate addiction, as well as how to work with it in the ordinary course of business. The study showed that social services have become better at using these methods in recent years and that today there are more tools available than before.

As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.

Outdoor recreation habits in metropolis and rural areasThis study aims to examine the perception of nature and outdoor recreation habits from an urban-rural prospective. The urbanization process continues in Sweden and the populations of the cities are growing continuously. Trends to build more compact and ?climate smart? reigns and with this a risk that green areas and areas where outdoor recreation can be practiced are situated further and further away from the urban population. Analyzing the responses from a survey made by the research program Friluftsliv i förändring 2007 we have examined if and which differences exists between urban and rural areas regarding their perception of nature, outdoor recreation habits and factors influencing the practice of outdoor recreation.

Construction companies are frequently criticized for high prices and long construction time. At the same time, statistics shows that construction workers are on the sick-list for occupational injuries or casualties more than other groups at the labour market.Skanska built a block of flats with tenant-ownerships in Gävle. The construction consists of concrete walls with in-fill walls in the front. The purpose with this degree project is to perform a risk analysis in work environment with focus on repetitive strain injuries and control the time report for in-fill walls manufactured in a field factory. The result of this project will help to make more realistic cost predictions in the future.This degree project has been performed in cooperation with the construction company Skanska.

The topic of this essay is whether the private owned ammunition factory Norma Projectile AB was a part of a war economy system from 1938 to 1943. This is done by analyzing specific documents from the company´s archives that expose the connection with Swedish authorities. The selection and analysis of these documents are based on four main criteria?s of the concept war economy. These criteria?s are based on Ivan T.

Already during the 90s, research showed that girls and boys are presented in different ways in judgments according to ? 3 LVU. While sexuality was given a large space in the girls' judgments, it was barely mentioned in the boys'. This study aims to investigate how the legal genders boy and girl are presented in judgments made according to ? 3 LVU during 2023.
