Sänkta sjöars inverkan på ytvatten i Västerbottens kustland : Samband mellan sänkningsnivåer och vattenkemi i sjöar på sulfidrika sedimentjordar

Lake lowering in sulphide-rich areas is currently a major environmental impact for surface water. This study focuses on whether there is a relationship between a gradient of lake lowering and surface water impacts in areas of sulphide-rich sediments, in order to better understand their contribution of heavy metals and sulfuric acid. Also, is it a reasonable method to use the reduced lake area in order to quantify the gradient? The survey was conducted by collecting water samples from reference lakes and lowered lakes from south to north in coastal areas within the county of Västerbotten. Water samples were then analyzed for TOC, pH, conductivity, anions, base cations, alkalinity, acidity, sulfate, Al, Cd, Fe, Mn, Cu, Zn and Pb.

Internkommunikation hos en mobiloperatör : ? en studie av motivation och upptagningsförmåga av information hos butikschefer

AbstractTitle: Internal Communication at a large mobile operator (Internkommunikation hos en mobiloperatör - en studie av motivation och upptagningsförmåga av information hos butikschefer)Number of pages: 43Author: Helena IsakssonTutor: Peder Hård af SegerstadCourse: Media and Communication Studies CPeriod: Fall term 2006University: Division of Media and Communication, Department of Information Science, Uppsala University.Purpose/Aim: The purpose of this essay is to gain an insight in how a corporations store managers motivation affects the degree of information they absorb from information channels.Material/Method: The method that had been used in this essay is quantitative.

The purpose of this study was to, from a client and therapeutic perspective, examine why drunk drivers begin treatment for their alcohol abuse and furthermore to investigate what?s important for the individual so that he completes the treatment.

Användarinvolvering i ett systemutvecklingsprojekt -Är det effektivt?

In most software engineering project, users are only involved in the beginning of the project as a help to design the requirements specification but users can be involved after this phase too, but is it effective to do so? With this report we would like to investigate how effective it is to involve users after the requirements specification has been written and approved. To find out how effective it is to involve the users we try some fast and simple involvement techniques on a quite far gone project. These techniques include ethnographic studies, prototypes and surveys. We also interviewed a couple of people who work with usability and finally delivered a report with our results to them to find out if they found our result relevant. By also documenting how much time we spent involving users we will show to which degree user involvement is effective. We found out that a couple of fast techniques could get very much result in the form of usability enhancing suggestions to the developers.

BackgroundResearch shows that the majority of patients feel anxiety before and during anesthesia. It has been shown in several studies that preoperative anxiety may cause adverse effects in the postoperative course. Nurse anesthetists have a key role in creating a safe environment and the opportunity to use different interventions to reduce the degree of anxiety.AimThe aim of the study was to examine which interventions may reduce anxiety in adult patients before and during both general, local and regional anesthesia.DesignSystematic literature review with a quantitative approach.ResultsSeveral studies indicate that gabapentin and pregabalin can reduce anxiety before and during anesthesia. The anxiety reducing effect appeared to be dose dependent. The naturopathic drugs Citrus aurantium blossom and Passiflora incarnata Linneaus were found to reduce anxiety before anesthesia.

Riskbedömning och abonnemangstandvård

I Sverige finns en betalningsform för tandvård som kallas ?Abonnemangstandvård? som innebär att du som patient har möjlighet att ingå ett avtal om tandvård till ett fast pris. I Värmland var man tidigt ute med denna modell och kallar den för frisktandvård för att belysa att man inte enbart ser det som en betalningsform utan även som ett sätt att bedriva vård. Tandläkaren genomför en initial riskbedömning inom fyra olika huvudområden och för respektive område allmän risk, teknisk risk, karies risk samt parodontal risk sätts en siffra 0-4 för att representera olika risknivåer. Ett sammanfattande mått leder i sin tur leder fram till en abonnemangsklass för patienten.

Medial opinion och aktiekursförändringar, finns det ett samband? ? En fallstudie på Swedbank under finanskrisen

Syfte: Syftet är att granska hur den mediala opinionen gentemot Swedbank förändras över tid och undersöka om dessa förändringar korrelerar med fluktuationerna i Swedbanks aktiekurs. Metod: I studien observeras Swedbanks aktiekurs under cirka elva månader och är till sin karaktär kvantitativ. Ungefär 6500 artiklar, skrivna om Swedbank under perioden, granskas genom semantisk dataanalys för att gradera opinionen på en skala. Metoden är ny och examensarbetet genomförs med en induktiv ansats. Materialet bearbetas därefter genom enkel linjär regression för att finna eventuella samband.

Patientrörlighetsdirektivets inverkan på svenska patienters möjlighet till gränsöverskridande vård : har förutsättningarna för hälso- och sjukvård i annat EU/EES-land förändrats sedan direktivets införande i svensk lagstiftning?

Most of my 16 students show a negative attitude towards mathematics and have difficulty understanding why they need mathematics to work as cooks. Their lack of knowledge has a negative effect on their work in the kitchen because they cannot master relatively simple mathematical solutions. The purpose of this study is to examine if an integrated working method of the subjects mathematics and cooking can change students? attitude towards mathematics and increase their understanding of the value of it in restaurant work. An integrated working method means to integrate the core subjects with programme specific subjects and that teaching is directed towards the main features of the vocational programme in order to create a holistic view.A theory of action research has been applied in this study, aiming to change something perceived as problematic through combining theory and practice in the cooking subject.

Attityder till arbetslösa -en studie av bakomliggande faktorer

Syfte och frågeställningar: Studien syftar till att undersöka vilka bakomliggande faktorer det finns för attityder till arbetslösa och hur dessa har förändrats under perioden 1986-2002. Utgångspunkten är att undersöka vilken inverkan politiska sympatier, erfarenhet/kontakt med arbetslöshet och reell arbetslöshet har på attityderna till arbetslösa. Den huvudsakliga frågeställningen är vilka samband man kan se mellan dessa tre variabler och attityder till arbetslöshet.Metod och material: Studien bygger på statistiska analyser av studierna Åsikter om den offentliga sektorn 1986 samt Åsikter om den offentliga sektorn och skatterna 1992, 1997 och 2002. Logistisk regression har varit den statistiska metoden som använts för analysen.Huvudresultat: Resultaten visar att erfarenhet och kontakt med arbetslöshet till viss del har samband med attityder till arbetslösa. Den viktigaste faktorn bakom attityderna är dock politiska sympatier.

EKONOMISKA SANKTIONER P? BEKOSTNAD AV M?NSKLIGA R?TTIGHETER? En kvantitativ studie om den regionala effekten av ekonomiska sanktioner p? graden av m?nskliga r?ttigheter i icke-sanktionerade l?nder

Previous studies have shown that economic sanctions have adverse effects on the level of human rights in sanctioned countries. The focus of research on the effects in sanctioned countries has left the question of whether economic sanctions can have a regional effect on human rights levels in countries not sanctioned in the same region. Therefore, this essay has sought to investigate if economic sanctions aimed at an individual state have a regional effect on the level of human rights in countries not sanctioned within the same region. A previous study found that economic sanctions in Latin America positively affected the level of human rights in non-sanctioned countries within the same region. This essay has examined whether the same result can be found in a region with a different level of democracy.
