Pappa, mamma, barn och psykisk hälsa : Socialt stöd från föräldrar i relation till psykisk hälsa

Mot bakgrund av socialisationsprocessen och de rådande genusnormerna som verkar inom denna, ämnar den här studien undersöka huruvida sambandet mellan socialt stöd och psykisk hälsa bland barn och unga varierar enligt könskompositioner mellan föräldrar och barn. Ytterligare ett syfte är att studera om ovanstående samband skiljer sig mellan äldre och yngre barn.Uppsatsen är kvantitativ och studiens analyser baseras på empirisk data från Barn-LNU och Barn-ULF (2000-2001). Analyserna genomförs med linjär regression med hjälp av statistikprogrammet SPSS (n=1,964).Resultatet visar att det finns ett samband mellan socialt stöd från föräldrar och psykisk hälsa bland barn och ungdomar i åldrarna 10-18 år. Detta gäller dock inte alla aspekter av socialt stöd. Resultatet visar vidare att den psykiska hälsan varierar enligt kön; pojkar har bättre psykisk hälsa än vad flickor har.

Sambandet mellan psykisk ohälsa och hälsorelaterade levnadsvanor bland kvinnor och män i en skånsk befolkning

Bakgrund: Daglig rökning och låg fysisk aktivitet på fritiden är betydligt högre bland individer med psykisk ohälsa. Syfte: Att undersöka dessa samband i ett köns- och socioekonomiskt perspektiv, samt eventuellt finna bakomliggande orsaker. Metod: Använder data från en tvärsnittsstudie (Folkhälsoenkät, Skåne 2000) med en representativ population (n = 11 304) i åldern 18-65. Huvudvariabler är självrapporterad daglig rökning och låg fysisk aktivitet, samt psykisk ohälsa som bedöms via General Health Questionnaire-12. Analyser gjordes med logistisk regression för att få oddskvoter och kontrollera för möjliga confounders. Resultat: Samband finns mellan psykisk ohälsa och daglig rökning, respektive låg fysisk aktivitet bland båda könen, och bland socioekonomiska grupper. Kvinnor har signifikant lägre oddskvoter gällande båda sambanden. Individer med psykisk ohälsa har fler ofördelaktiga levnadsvanor än de med ej psykisk ohälsa, oavsett socioekonomisk status.

Kan relationen mellan CSR och lönsamhet stödja svenska finansbolags undermåliga samhällsansvar? - En kvantitativ studie med beaktning av endogenitetsproblemet

Introduction: The concept of CSR was first coined in the 1950?s and refers to corporate vol-untary work to contribute to a sustainable society. In Sweden, companies within the finance sector are among the worst when it comes to implementing CSR in their daily work. The debate on whether companies should engage in CSR activities or not, is extremely relevant nowadays. Right now we are facing a time where the demand on companies to take their social responsi-bility becomes more intensified.

Planering av vägupprustning med hjälp av GIS och optimering : en fallstudie på Holmen Skog

The objective of this thesis was to develop a method for the planning of road upgrading at Holmen Skog, a Swedish forest company. A critical issue for creating such plans is to identify roads that are suitable to upgrade to a standard that can handle heavy traffic during spring thaw, since spring thaw is a bottle neck for transporting timber. The method was tested in a case study at a district. The work consisted of two parts. The first was to retrieve and prepare geographical data for the roads.

Läroboksspråk : En studie av språket i två historieböcker avsedda för grund- respektive gymnasieskolan

This essay investigates and compares the readability in two different schoolbooks: Eko Historia (the primary school grade 4-6) and Epos Historia (the upper secondary school). The questions of the survey are:- Which differences in linguistic and layout can be found between books meant for the primary school and books meant for the upper secondary school?- Are the texts easy to read according to the former research in readability?In order to answer the questions structural dimensions as lexicon, syntax, bounds between sentences and narrative voices have been studied. Also the texts disposition and typography have been examined.The results demonstrate that the book designed for the primary school has a verbal structure with an explicit vocabulary, lots of verbs and short sentences. A clear narrative voice gives an impression of spoken language.

Vem använder budget? : En kvantitativ undersökning av budgettillämpningen i olika organisationer

Weber and Linder (2005) have enlightened that the focus of the current debate on the budget?s to be or not be, has been on trying to find a general tool, which fits best in all situations. They argue that the budget may be more appropriate for organizations in certain circumstances, than for others. They claim that there is a gap in research concerning the situations in which the budget may be appropriate, or when Beyond budgeting is preferred. It is this gap we are trying to fill with our thesis.The purpose of the thesis is to explain which situational factors that affect the organization's use of budgets for the functions the budget can fulfill.

Cirkelträning - en kombination av styrka och kondition

In Sweden the amount of people with obesity has increased with almost 50 % during the past 20 years and is now including 500 000 people. A larger energy intake than energy consumption is today one of the most important cause of overweight and obesity that exist in the world. This requires more knowledge about healthier eating habits combined with moderate intensive exercise, exercise that is simple, effective and amusing. A god solution is a combination of fitness training and strength training, a type of circuit training. It is distinguished by a high intensive work in short periods and with a short break.

Textinnehållets betydelse för läsförståelsen : En komparativ studie av flickor och pojkar i åk 7

Research reports as PISA and PIRLS show that reading comprehension among Swedish students have deteriorated in recent years and that girls have better reading comprehension than boys. The basis for this study is Maj-Gun Johansson's reading comprehension test done during the four years between the years 2005-2008 in the seventh grade in a municipality in Sweden. The main purpose of this study is to examine reading literacy in terms of the influence of content and form of texts viewed from a gender perspective. The study is divided into two parts. The first part is a survey on local reading comprehension compared with results from a similar national text.

Effektivisering : En utredning om åtgärder på en industrifastighet

AbstractDelta Terminal owns an outdated industrial building which they now rent out to businesses. This property currently has a high energy con-sumption and therfore it is desirable to improve the efficiency. In ordet to reduce the energy consumption within the industrial building enve-lope, the heating systems and lighting are being investegated. A good building envelope emits less heat and thus reduces the energy consump-tion. An energy audit is a tool used to determine the energy loss.

Vita vingar och röda bär -en folkloreinspirerad mönsterkollektion

The aim of this examination project was to work with the processof making a pattern collection for fabrics. The collectionshould consist of at least three patterns with report measurementssuitable for screen print. I wanted the pattern collectionto be a simple, mystic and colourful collection with a folklorespirit like the popular rural life I experienced during my childhood.The purpose of the project was that I during the working processwould deepen my estethic background to enforce my personalgraphic expression ability and evolve as a pattern designer.I wanted to try to mix my personal view of domestic graphicexpression with another language that I gained in recent years.This I wanted to do in order to find the tools that could helpme clarify and develop my pattern signature.A few of the questions that I had about this project were if thelong scetching phase that I planned would help or damage theproject.I also thought it would be interesting to experiment with coloursin this project. I wanted to see how far I dared to go inmatter of colours as well as how the patterns would be visuallyexperienced if I for example reduced one colour or replaced itwith the opposite colour.I thought it was inspiring to work with traditional techniqueswith the colours. It was only positive that part of the patternstory telling was developed in an unpredicted direction duringthe scetching phase.

Simulering av miljoner grindar med Count Algoritmen

A key part in the development and verification of digital systems is simulation. But hardware simulators are expensive, and software simulation is not fast enough for designs with a large number of gates. As today?s digital zesigns constantly grow in size (number of gates), and that trend shows no signs to end, faster simulators handling millions of gates are needed. We investigate how to create a software gate-level simulator able to simulate a high number of gates fast.

Jag bara lärde mig! : En studie om typografi i läromedel för läsinlärning

We studied the initial process of reading, with a focus on typography, whether it ispossible to increase childrens lust to read in the age six to seven years old, byadjusting the typography and graphic design. We conduct this study through qualitative and quantitative studies, mainlyinterviews with a main focus on children in this particular age were used. In additionto the interviews a questioniare were sent out to a selection of students. The studyalso contained an interview with a pedagogue as well as studies of the current andexisting textbooks and teaching aids that is used on the school we are looking into.During the study we consulted educated pedagogues to get an understanding of thechildren and their learning and to be able to approach them in a suitable way.The theories we have been using were mainly from a typographic point of view.Other areas we explored were theories about reading processes. This study showedthat every child needs a method that is suitable for them and that the materialprovided today is typographically inconsistent. The childrens and teachers needs andwishes in typography did not correspond with the current teaching aids design. From this study the followning points were made about how to design a textbook forchildren in the first grade:? The typeface should be a sans serif.? The point size should be bigger than 12 points.? Text should be aligned to the left.? Sentences should be short without becoming abstract.? To maintain focus on the text the layout should be simple and unbarked.? The format should be designed after the pourpose of the publication, forexample when it is a complement to the textbook, the format should be of suchcharacter that it is easy for the children to bring home.? There should be a typographical consistency through all of the materialsprovided to the children..
