Riktvärden för förorenad mark : En undersökning av hur riktvärden för förorenad mark har förändrats gentemot tidigare riktvärden samt hur de påverkas av variationer i geologiska och hydrogeologiska parametrar
Risk assessment is made to determine risks with contaminated areas and to determine which treatment the area requires. In Sweden, risk assessment is divided into three levels: risk analysis, facilitated risk assessment and detailed risk assessment. In detailed risk assessment site-specific guideline values are developed to compare with values of contaminants that are measured in the area.Site-specific guideline values vary with geological and hydrogeological parameters. The purpose of this report is to examine which of these parameters that affect the guideline values. The examination was done using a calculating program for consideration from the Swedish Environmental Protection Agency from the year of 1997.
Vad är ?rätt? gjutkvalitet? Hur uppnås det?
Ever since ABB has begun diecasting their rotors instead of permanent mold casting it,variation in the quality of the cast has arisen. Diecasting is performed in three differentmachines, M1, M2, M3 with 400, 660 respectively 800 tons of die locking pressures.The aim of this thesis is to answer the following questions:What is the ?right? cast quality? How is the right quality achieved?For sizes 160-180 solutions will be proposed that consider eccentricity between thelaminate and the short circuit ring as well as elimination of the thin Al film that appearson the outer periphery of the rotors.Through considering the statistic material the most often diverging rotor type has beenidentified and one of the actual rotors has been sent to a laboratory to be analyzed inorder to establish the current defects. The result of the analysis shows that there areplenty of gas- and oxide-porosity.It has been proved that every time the dies temperature decreased below 120°C thecontent of gas porosity increased. It is due to rapid solidification of metal that flowsthrough the ?cold? laminate.It has confirmed that enhanced porosity in squirrel cage causes high impedance in therotors.
Ger en kvinnlig CFO högre redovisningskvalitet?
The executives of a firm possess considerable influence over a company's financial reports. The numbers can be adjusted in a favorable direction by engaging in Earnings Management, which harms the reliability of the financial reporting. Previous research suggests that Earnings Management can differ between genders. In recent years the debate about a woman's role in the business world has received generous attention in media. Moreover, the presence of women in leading positions has become a relevant issue for firms.

Marketing tools in grocery retailing, do they affect store loyalty?
The purpose of this study is to provide a longitudinal examination, within grocery retailing, of four marketing tools and their impact on enhancing customer loyalty. The study examines whether the relationship between the four marketing tools and customer satisfaction has a positive effect on attitude and behavior loyalty. The findings from this study show that the marketing tools have not helped enhancing loyalty between 2004 and 2007. Between these years, service quality has the most affect on loyalty. Self-scanning as an effective marketing tool could be questioned, the relation in this study is not supported.
"Har du damp eller?" : En studie av omgivningens betydelse för hur en ADHD-diagnostiserad individ upplever sin livskvalitet
Syftet med denna studie är att genom kvalitativa metoder undersöka omgivningens betydelse för hur en ADHD-diagnostiserad individ upplever sin livskvalitet samt undersöka vilka faktorer som är av betydelse för den diagnostiserades välmående. Det material som presenteras har genererats utifrån elva kvalitativa intervjuer med individer som antingen är diagnostiserade med ADHD, lever i nära relation med en ADHD-diagnostiserad individ eller arbetar med ADHD. Det presenterade materialet analyseras sedan utifrån relevanta socialpsykologiska teorier av Becker (2006), Goffman (2006) och May (2013).Resultatet visar att omgivningen har en stor betydelse för hur den ADHD-diagnostiserade individen upplever sin livskvalitet. Den problematik som ADHD-diagnosen bidrar med försvårar för individen att leva upp till de krav och normer som förväntas av deras omgivning. Detta leder till att den diagnostiserade individen kan definieras som avvikande från gruppen och riskerar att hamna i ett utanförskap. Individen riskerar att identifiera sig med de egenskaper som omgivningen tilldelar den för att leva upp till de rollförväntningar som ställs på den och spela en roll de inte trivs med i strävan efter bekräftelse och att känna tillhörighet..
Undersökning av sambandet mellan strålningstemperatur och NDVI i Sahel
Several studies have analysed the relationship between Normalised DifferenceVegetation Index (NDVI) and radiative surface temperature. A main goal for moststudies have been to find the best method for carrying out land cover classificationsand to study land cover changes, based on a combination between the twoparameters. Since atmospheric components have a significant influence on bothparameters, most applications were based on multi-temporal data. The quality of theindividual values in such a combination is improved, but the biophysical justificationis uncertain. This study presents a different method, based on only the combination ofvalues that have been registered the same day and about the same time of the day.125 daily images of NDVI and 250 images of radiometric temperature were used inorder to analyse the relationship between (1) NDVI and radiative temperature and (2)NDVI and relative temperature difference between early morning and mid-day.Results between NDVI and radiative temperature show a significant negativecorrelation on areas where a distinct growing season develops, and a strong positivcorrelation where vegetation is abscent throghout the season.
Stress i socialt arbete : - en risk för utbrändhet?
The purpose of this study was to investigate how social workers who worked with financial assistance perceived their work situation and the impact work-related stress had on their health and quality of work. Further, the study intended to find out if they felt that they received support from their employer that could prevent stress-related sick leave. The following two research questions were to be answered: In what way does work-related stress affect social workers? health and job quality according to their own experience? What kind of support and help experienced social workers were available within their organization? To receive answers to the questions semi-structured interviews with five social workers were conducted, analyzed and interpreted. The results showed that when social workers have a heavy case burden, high stress and a risk of deteriorated job quality occurred.

Effekter av kalavverkning på mindre boreala sjöars vattenkvalitet
Forestry is an important industry in Sweden, with clear-cut as the most commonly used method for harvesting. Here the long-term impact of clear-cut on lake water quality (dissolved organic carbon (DOC), nitrogen, phosphorus and pH) has been investigated, based on 23 lakes sampled during autumn. Data for additional 15 lakes sampled for the Swedish monitoring program were also used. Lakes were classified as 5, 25, 40 and 60 year based on data of the forest age in the catchment, gathered from the Swedish national forest inventory. Clear-cut lakes were classified as 5 years (>20% of the catchment clear-cut during the last 10 years).

Kvalitetsgranskning av skadeförebyggande åtgärdsförslag i miljökonsekvensbeskrivningar
I en miljökonsekvensbeskrivning, MKB ska en beskrivning av planerade åtgärder ges för att undvika, minska eller avhjälpa skadliga verkningar, då projektet antas medföra betydande miljöpåverkan. Eftersom det upptäckts allvarliga brister för skadeförebyggande åtgärder i forskningsrapporter utomlands, var det intressant att undersöka åtgärdskvalitén i några svenska MKB. Svagheter och styrkor i skadeförebyggande åtgärder i 6st MKB för 2st markkabelanläggningar i Sverige undersöktes. Metoden för undersökningen var två fallstudier som jämfördes mot varandra och analyserades mot teorier. Resultatet visade att kvalitén på det undersökta materialet var övervägande bra, jämförelsevis mot de forskningsrapporter som visat på bristfälliga åtgärdsförslag utomlands.
Vad är hållbarhetsredovisning? : En kartläggande litteraturstudie
Företag som upprättar så kallade hållbarhetsredovisningar har blivit allt vanligare. Dock råder det inom forskningen på området en oenighet om vad hållbarhetsredovisning egentligen är. En mängd olika begrepp används om vartannat och några klara definitioner finns inte fastlagda. Syftet med denna studie är därför att göra en kartläggning av de olika begrepp som används inom den globala, akademiska hållbarhetsredovisningslitteraturen för att utreda innebörden av dessa begrepp samt för att utreda hur dessa begrepp förhåller sig till varandra. Studien genomförs med hjälp av en litteraturstudie där 12 artiklar väljs ut genom ett intensitetsurval och sedan analyseras och jämförs med varandra.
