Projekteffektivitet inom tekniska utvecklingsprojekt : Vilka faktorer påverkar projekteffektivitet och hur kan dessa mätas?
The purpose of this thesis is to identify the factors that drive efficiency and effectiveness in technical development projects performed at A?F?s department of product development. In addition to identifying and analyzing these factors, the thesis also analyzes what needs to be taken in to account in order to implement a measurement system that is able to both monitor and control the identified factors.The thesis has been performed in a qualitative manner. It is based on interviews with people from several different technological companies, within different lines of business, all of which are customers to A?F?s department of product development.The results show that there are seven critical factors for project efficiency and effectiveness.
Den erfarne ripjägaren : Optimalt födosök hos homo sapiens?
The purpose of this study is to examine some factors that make a human grouse hunter to prolong and increase its hunting effort. The theory of optimal foraging is used for explaining their behavior.The data of this study is collected from a web-based inquiry from 2007 answered by grouse hunters in Sweden. The method that has been used is mainly bivariate statistics and logistic regression analysis.Key findings shows that an experienced grouse hunter has more than 5 times the chance of prolonging hunting effort when grouse density is high, compared to a beginner grouse hunter. On the same time experienced grouse hunters also stop hunting in advance when grouse density is low to a larger extent than inexperienced hunters. Other factors of importance for prolonging the hunting effort for a day are age and the travel distance to the hunting area.
En jämförande studie över metoder för att mäta syreförbrukande ämnen med och utan kvicksilver i avloppsvatten från pappersindustri
Kvicksilver är ett av de farligaste miljögifter vi känner till. Regeringen har därför arbetat fram ett förslag till förbud mot kvicksilver som kemikaliereagens från år 2004. Detta förbud innebär att många laboratorier måste byta analysmetoder. Vid analys av CODCr används kvicksilversulfat för att minska interferens från klorid. Bravikens pappersbruk använder en CODCr-metod som innehåller kvicksilver.
Lägersmål och lönskalägen i Bergslagen 1771-1830
Barnamordsplakatet (a Infanticide Proclamation) of 1778 was a circular allowing unmarried mothers to give birth at an undisclosed location without giving up the name of the father. The proclamation was supposed to ease the situation for the unwed mother in Sweden.The aim was to investigate whether women in Assembly of Hällefors, far from government and close to remote forest Finnskogen, was affected by the Infanticide Proclamation, between 1771 and 1830.Case studies has been done on people who had illegitimate children, if they were convicted, what the crime was and what the punishment was. The investigation is made at a local level and compared against national analyzes on the same theme.A lot of illegitimate children were born in Grythyttan nearby and slightly less in Hällefors, compared to other places of Sweden. Mothers and fathers were convicted in the district court for crimes, including, sexual intercourse between unmarried persons. More women than men were convicted.
Genusstrategier i förskolan : En studie av en förskolas arbete med att motverka traditionella könsroller, ur ett intersektionellt perspektiv
The purpose of this study is to examine a preschool's work to counteract traditional gender roles, which strategies are used and how norms about gender roles are produced and treated. The study also examines whether the preschool has an intersectional perspective in it's gender work, which analyzes how they relate to other categories such as ethnicity, race, class, age and sexuality in their work. I have been observing and conducting four interviews with teachers at a preschool with a gender profile. In my analysis I have used Foucault's theories about discourse and power. The results show that the informants had a high awareness of gender and that the main strategies used were: an individual perspective, seeing the individual and not the sex, and a gender-neutral strategy, removing everything that is gendered, for example, in language and environment.
Miljöanpsassad metod för hjultvätt
In order to avoid harmful substances ending up at the municipal sewage treatment plants, it is important to purify the wastewater at the source. One such source is the wheel washers available in many tire garages which are used to wash the wheels on our vehicles when we change between summer and winter tires. It is important to wash the wheels before storage, to extend the tires lifetime. The purpose of this study is to find a green innovative solution for reduction of emissions of heavy metals at the source, so that the sludge from the sewage treatment plants can be used as fertilizer. The target is to find a wheel wash method which leads to compliance with the guidelines for car washers, and that also provides a better washing result than with the existing method.
Vad bestämmer fonders prestation och avgift? : En studie på svenska aktivt förvaltade aktiefonder under perioden 2005-2014
This study analyzes 66 Swedish actively managed mutual funds investing in the Swedish stock market during the period 2005-2014. The purpose is through pooled data regressions analyze the relationship between both the mutual fund?s annual fee and risk-adjusted return to the fund?s characteristics. The characteristics of the study are the size of the fund's assets, age, if the fund is bank managed or not, Tracking Error, and standard deviation of return.By using the performance measures of CAPM, Fama and French 3-factor model, and Carhart?s 4-factor model monthly risk-adjusted returns are created for all funds over the period.
Markavvattningsföretagens geografi och konsekvenser i Trosaåns avrinningsområde
Agricultural drainage is widely used to manage the amount of water in the ground in order to improve conditions for cultivation. However the effects of drainage companies on water regimes are considerable leading to runoff changes such as altered stream flows, peak flows and water levels. In a greater extent this could imply an increased risk for floods along affected watercourses. This study analyzes the extension of agricultural drainage within the drainage basin of Trosaån in Sweden by ArcGIS mapping. In a statistical analysis, historical variation in streamflow in relation to mean precipitation and mean temperature are investigated for the study area.
Matematiska utmaningar i grundskolans tidigare år : En studie om hur elever med särskilda matematiska förmågor identifieras och utmanas i grundskolans tidigare år
I denna rapport undersöktes S&P 500 Energy Index genom multipel regressionsanalys. Modellerframställdes genom regression och baserades på data hämtad från börsen. Modellerna angavs iprocentuell ändring respektive absolut ändring. Validitet för varje enskild kovariat testades och en risknivå avgjorde om en kovariat skulle inkluderas i modellen eller inte. Detta ledde till två modeller med bättre kurvanpassning till den givna mängd data över det valda energiindex.
Priset på Poker ? En studie av efterfrågeelasticiteten på Internetpoker
Studien baseras på en kvantitativ metod med starka kvalitativa inslag. Syftet med studien är att med hjälp av ekonomisk teori och ekonometriska modeller försöka bestämma efterfrågeelasticiteten på Internetpokermarknaden. Vi har i studien utgått från att efterfrågefunktionen på Internetpokermarknaden är en konstant elastisk nyttofunktion. Då priset i Internetpoker är en komplicerad variabel att skatta konstruerade vi en prisformel. För att kunna vikta de olika variablerna som ingick i prisdefinitionen genomförde vi en surveyundersökning.
Kapitalstrukturens inverkan på företags lönsamhet och värde : En empirisk studie över svenska börsnoterade fastighetsbolag
How capital structure influences corporate performance and value has been in the interest of researchers and scholars for more than half a century, but an answer is yet to be found. The main objective of the present paper is to contribute with data for this cause and hopefully help to clarify this mystery. The method that was used was by analyzing the impact of debt on profitability and market valuation through linear regression. The study examined 17 Swedish property companies listed on Nasdaq OMX Large Mid and Small Cap over a 6 year period (2007-2012). The authors found a slightly negative relationship between debt-to-equity and profitability measured by return on equity (ROE) as well as by return on assets (ROA).
Är svenska aktiepriser trögrörliga? : En studie av tidsförskjutningar i prissättningen av värdepapper i samband
BakgrundRichard J. Rendleman, Charles P. Jones & Henry A. Latané påvisade i en studie år 1982 med hjälp av en regressionsmodell att tidsförskjutningar i prissättningen av aktier existerat på den amerikanska marknaden vid kvartalsresultat som avvek från en trend. Det inspirerade oss att med samma metod undersöka om liknande tidsförskjutningar även existerat på den svenska marknaden.SyfteSyftet med denna uppsats är att empiriskt studera om det existerat tidsförskjutna aktieprisjusteringar kvartalsvis, baserade på standardiserade oförväntade kvartalsresultat respektive standardiserade oförväntade kassaflöden, på den svenska aktiemarknaden under åren 2004-2006.
Islam på universitetet. En innehållsanalys av islamisk predikan på Chalmers
This paper analyzes the content of eight Islamic Friday-sermons, held at Chalmers Technical University in Gothenburg in spring 2010, organized by Chalmers Islamiska Förening (CIF) (Chalmers Islamic community).The forces of globalization, the accessibility of information and the Internet have given rise to discourses and movements that know no national boundaries. The accessibility of these global movements and discourses through media, Internet, etc., affect the way Muslims in Sweden interpret and practice their religion. Thus, this paper includes discussions and descriptions of global Islamic revivalist-movements, and relates the contents of the sermons at Chalmers to these movements. In the sermons, the imams often discuss the concept of a global Muslim community, the umma, and their perceptions of the prescribed ethics linked to this community. They often relate this discussion of ethics to frequently discussed issues in the West such as equality, justice and ethical standards in war.
Varför ska vi gå till skolan? : En kvalitativ studie om skolk på gymnasiet utifrån ett sociologiskt perspektiv
The aim of this paper is exploring questions regarding the problem of absenteeism among high-school students in Sweden. Fifteen students attending an urban high-school have been interviewed about their views and experiences of absenteeism. The author analyzes the students? answers by taking into account two different sociological approaches which give two different explanations about the way young people experience and estimate education. The French sociologist Bourdieu theorized that differences in cultural capital influence the permanent internalization of patterns of thought and behavior.
Kostnader för välfärdstjänster i Västra Götalands kommuner
This bachelor?s thesis examines costs of welfare services in municipalities of the region of Västra Götaland in Sweden. Previous research provided reasons to expect a link between costs of welfare services and demographic changes. Furthermore, Willam J. Baumol?s theory about ?the cost disease? also provided reasons to expect a link between welfare services and salary levels.
