Ung och full : en kvantitativ studie om ungas riskbruk av alkohol
Recent statistic shows that about 28% of adolescents living in Stockholm drink alcohol at such a high level that their consumption counts as risky drinking. The correct term to use in this matter would be binge drinking adolescents. In the more wealthy areas of Stockholm this group of binge drinking adolescents counts for as much as a third of the population. In contrast, the adolescents living in exposed areas do not drink nearly as much. Binge drinking adolescents in these areas only counts for 15%, nearly half as much as in the wealthy areas.In light of this the intentions of this study is to investigate which explanatory factors that can clarify the range-rated differences in binge drinking between adolescents in Stockholm.
Börsmisslyckande - En studie av misslyckade börsintroduktioner på Stockholmsbörsen
Vi vill med vår uppsats försöka hitta förklaringar till varför börsintroduktioner misslyckas. Med dessa förklarande variabler vill vi försöka skapa en modell som kan förutse huruvida en introduktion kommer bli lyckad eller ej.Teorin bygger på aktuell och tidigare forskning om misslyckade börsintroduktioner. Det redogörs även för förekommande begrepp och variabler.Vi använder ett kvantitativt angreppssätt för att besvara uppsatsens problemformulering samt uppfylla dess syfte. För att hitta de variabler som förklarar en misslyckad börsintroduktion använder vi oss av en logistisk regression.De variabler som vi funnit som kan förklara en misslyckad börsintroduktion är företagets ålder, dess skuldsättning, huruvida företaget är uppbackat av venture capital eller ej samt andelen kvarhållna vinster i förhållande till totala tillgångar. Den modell vi skapar förutser en lyckad respektive misslyckad introduktion i 69 procent av fallen..

Elförbrukningen i svenska hushåll : En analys inom projektet ?Förbättrad energistatistik i bebyggelsen? för Energimyndigheten
Energimyndigheten har drivit ett projekt kallat ?Förbättrad energistatistik i bebyggelsen? för att få mer kunskap om energianvändningen i byggnader. Denna rapport fokuserar på ?Mätning av hushållsel på apparatnivå? som var ett delprojekt.Diverse regressionsmodeller används i denna rapport för att undersöka sambandet mellan elanvändningen och de olika förklarande variablerna, som exempelvis hushållens bakgrundsvariabler, hushållstyp och geografiska läge, elförbrukningen av olika elapparater samt antalet elapparater.Datamaterialet innefattar 389 hushåll där de flesta är spridda runt om i Mälardalen. Ett fåtal mätningar gjordes på hushåll i Kiruna och Malmö.Slutsatsen vi kan dra från denna uppsats är att hushållens bakgrund, hustyp, geografiska läge och antal elapparater samt dessa apparaters typ har relevans för elförbrukningen i ett hushåll..
Utvärdering av den svenska cykelhjälmslagen för barn under 15 år : Analys av nationella trender i cykelrelaterade huvudskador mellan 1998-2011
Introduction: In January 2005, a nationwide mandatory bicycle helmet law for children under the age of 15 was introduced in Sweden. In the current study, the effect of this law was evaluated by analyzing national trends in hospital admissions due to bicycle-related head injuries during the period 1998-2011.Methods: An interrupted time-series design with segmented regression analysis was used to evaluate the intervention effect on head injuries as a percentage of all injuries (%HI) among cyclists in age- and sex-specific groups. Effect was measured as a change in level and/or slope of the trend at the time of legislation.Results: A total of 35261 cyclists (0-54 years) were hospitalized due to a bicycle injury during the study period. Linear regression analyses of the entire study period (not segmented) showed significant year-to-year decreases in the %HI of 1.3-1.7% in all age and sex-specific groups (p < .0001). Results from the segmented regression analysis showed that, at the time of legislation, a significant drop in level occurred among males under 15 years (-4.5% [95% CI: -7.7% to -1.3%], p = .01) and a significant change in slope occurred among females aged 30-54 years (-1.6% [95% CI: -2.9% to -0.2%], p = .025).Conclusions: The law seems to have had an effect on males in the target population (<15 years).

DEHP - från mjukgörare till hormonstörande
Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.
Kvinnor i kommunala nämnder : En kvantitativ studie i kvinnopolitisk representation
Over the last decades there has been a steady increase in the representation of women on the political arena. Despite of this there are still fewer women in comparison to men in political organs particularly at the municipal level. It is therefore of great importance to examine which different factors that tend to effect the female representation at this level. Doctor of philosophy at Umeå University Jessika Wide presented in a study from 2000 that the share of women in the municipal councils tended to depend upon cultural, socio-economical and political factors. Other scholars also mean that women have specific interests and therefore are more represented in some areas.
Språk, kultur & handel i ett svenskt perspektiv
Sverige är ett exportland med lång tradition av handel med omvärlden. För att kunna utnyttja våra absoluta och komparativa fördelar gäller det att vi har god kunskap om vad som påverkar vår handel. Dagens konsumenter har ett stort antal produkter att välja mellan. Handla har aldrig varit lättare och med hjälp av internet är det möjligt att handla varor från andra sidan jordklotet med minimal ansträngning. Vi ställer oss frågan, har vår språkkunskap och kultur en inverkan på den internationella handeln? Denna fråga ska försöka besvaras med hjälp av ett bland de vanligaste verktygen vid skattning av bilateral handel, den så kallade gravitationsmodellen.
