Barn till alkoholmissbrukare : en studie av barnens uppväxtvillkor och det sociala nätverkets betydelse
Our purpose with this paper was to examine what effect a parent's drinking problem can have for the children in the family. A combination of literature study and qualitative interview analysis was used. The most important research questions were: How do the parent's problems affect the child? In what ways can the social network around the child help it to develop normally despite problems in the home environment? To what extent a parent's drinking problem affects a child depends on many different factors. Based on earlier research and interview data we drew the conclusion that growing up in a family where a parent has a drinking problem has a negative effect on all children.

Bremsningens effekter hos häst : utvärderat med hjälp av termografi, hormonanalyser och hematologi
Twitching is frequently used in horse management because of its sedating and pain-relieving effects. In this study, the effects on the horse?s nervous system by twitching were investigated by thermography of the skin temperature. The temperature is regulated by the sympathetic nervous system through postganglionic sfincters at the capillaries of the skin. The effects on the endocrine activity have also been studied by the measuring of ACTH and cortisol in blood plasma.
Effekten av betainsupplementering på prestationsförmågan hos vältränade cykelatleter
Bakgrund: Syftet med denna studie var att undersöka effekten av sju dagars tillskott av betain (2,5 gram/dag) på prestationsförmågan i idrottsspecifika tester för manliga vältränade cykelatleter.Metod: Sex (n=6) manliga testpersoner (genomsnitt ± standardavvikelse ålder, 31,7 ± 10,2 år; längd, 188,2 ± 3,6 cm; kroppsvikt; 82,5 ± 7,6 kg; fettfri massa, 71,6 ± 7,3 kg) genomförde förtester bestående av fem counter movement jumps, fyra stycken 12 s wingate-sprinter med 2,5 minuters aktiv vila följt av fem ytterligare counter movement jumps. De blev sedan indelade slumpmässigt i betain- eller placebogrupper. Första testet etablerade basvärden och eftertest ?1? samt ?2? föregicks med antingen sju dagars tillskott med placebo (2,5 g maltodextrin plus 12,5 mg riboflavin) eller betain (2,5 g trimetylglycin plus 12,5 mg riboflavin). Riboflavin användes för att undanröja den fiskliknande doften som kan uppstå vid tillskott av betain.
Förebyggande effekter av fysisk aktivitet på depression : ? en litteraturstudie
Objective: To study the evidence on physical activity (PA) as an effective preventive strategy for depression.Methods: A search of electronic databases was performed for articles between 2007 and 2012, both original research and review articles, concerning the link between PA and depression on children, youth and adults. Three reviews, five longitudinal and two cross sectional studies were included.Results: PA reduced the likelihood of depression in many studies and a sedentary or inactive lifestyle increased the risks for mental health symptoms such as depression. One study showed that low PA in childhood increased the odds of depression as an adult and other studies on teenagers saw a connection and mediation between PA and self-esteem whereas physical fitness showed no mediating effect. Many of the studies and reviews point out the insecurity regarding the dose-response association and the difficulties in defining causality.Conclusion: PA might have a preventive effect on depression. Some evidence exist to support that PA in childhood prevents depression in adults.

Prehospital vätskebehandling vid stort trauma ur en sjuksköterskas perspektiv : En systematisk litteraturstudie
The aim of this study was to determine which type of fluid to use in trauma care to improve patient survival. The method used was a systematic review, where a total of 18 studies were reviewed and 13 included in the results. The inclusion criteria used in this study were Randomized controlled trial, or studies relevant for the purpose, written in English and published during the last ten years. The studies were identified in the PubMed data base. The results showed that in trauma with hypovolaemia, colloid infusion has a better effect than infusion of crystalloid fluid on blood pressure and colloid infusion reduced the body's cascade systems in a beneficial way. Colloid infusion administered to head injury patients lowered their intracranial pressure more than crystalloid infusion.

Planet rendering plays an important role in universe visualization and geographic visualization. The recent tools and methods allow better data acquisition, usually with very high resolution. However in computer graphics, there is always the limitation on the resolution of geometry and texture due to numerical imprecision. Not many applications can handle high resolution data effectively.This thesis introduces, Implicit Surface Scene, a level of detail scene management inspired by dynamic coordinate system and SCALEGRAPH? which change over time depending on the current camera position relative to the planet surface.

?Var är den goda glassen?? : En studie av föräldrar till barn med neuropsykiatriska diagnoser och deras upplevelse av samhällsstödi biografier
AbstractThe aim of this qualitative study was to investigate how parents of children diagnosed with Autism, Aspergers Syndrome or ADHD/ADD describe their experience of the Swedish welfare support system in written biographies. To answer this question a study of five biographies written by parents with children diagnosed with ADHD, Autism and Asperger Syndrome where made. The conclusion was that the social network itself is of great importance to the parents. Families with single parents experienced a less positive experience of the Swedish welfare support system than parents with a spouse. The study also reveiled that families with a supporting social network and a solid financial ground in combination had the best experience of the Swedish social welfare support system.
En komparativ studie av vinstdelningssystem bland advokatbyråer
Law firms are defined as knowledge-intensive companies. Due to the dependency regarding the resource of knowledge among the firms employees and to the fact that they often are categorised as a type of professional service firm. The purpose of this study is to investigate the different types of profitsharingsystems as a form of reward with focus on the theoretical differences and effects of the True Partnershipmodel and the Stockholmmodel. In addition to these models we will look into the Human Resource processes of; recruiting, integration, retaining and development of employees. The main purpose of the study is to examine the theoretical level on how the profitsharingsystems effect different Human Resource processes and through the knowledge of these connections using this as an analogy when to analyse other law-firms and knowledge?intensive company?s.
UPPFATTNINGAR AV ETT NYTT RYSSLAND?V?RNKRAFT ELLER STRATEGISK TIMEOUT? Inverkan av Rysslandsuppfattning p? svensk-finsk nedrustning 1995?2009
This study investigates Swedish and Finnish official perception of Russia following the Cold
War. This is aimed at categorizing changes in perception of Russia over time and assessing the
impact of perception on defense policy. The study uses a comparative method where the
contents of three foreign policy reports of Sweden and Finland respectively are analyzed
according to dimensions based in image theory. Results show that Swedish and Finnish
perceptions of Russia are overall similar between the reports being compared, except for
Finnish perception of Russian relative power being significantly greater. Changes in Swedish
and Finnish official perception do not clearly correlate with changes in defense policy.
