Styrelsen och samhällsansvaret - En studie om hur styrelsesammansättningen påverkar CSR-prestation i svenska börsbolag
The composition of the board of directors and Corporate Social Responsibility (CSR) are two widely researched subject and discussed by the media. This study aims to examine the impact of the board of directors' composition on CSR performance among the largest companies listed on Nasdaq OMX stock exchange 2008 in Stockholm, Sweden. A linear regression analysis is applied to investigate the relationship and evidence is found that board attributes have an effect on CSR performance. Among these; the size of the board, outside directors and employee representatives all have a positive impact on environmental performance. Furthermore; female, outside directors and employee representatives have a positive impact on social performance.
Fortkörning - en inkomstfråga? : En studie utav inkomstens påverkan på benägenheten att köra för fort
The purpose of the thesis is to investigate whether a higher income make individuals more likely to exceed the speed limit. In addition to income the variables age, sex, perception of the speed of the average driver and offense history for the last three years are taken into account.The method used is based on a survey performed at the mandatory annual motor-vehicle inspection (Bilprovningen). 177 individuals were asked to participate, of these, 124 completed the survey which in turn left us with 117 usable observations.The analysis is based on two forms of regression, a linear regression and an ordered logit regression to confirm the results for the ordinal data.The final model indicates a result where income and age are statistically significant. Sex is considered insignificant for our data material and is excluded from the model. Age has a negative effect on the propensity to exceed the speed limit while income has a positive effect.
Automatisk detektering av diken i LiDAR-data
Den här rapporten har utrett möjligheten att automatiskt identifiera diken frånflygburet insamlat LiDAR-data. Den metod för identifiering som har valts harförst skapat en höjdbild från LiDAR-data. Därefter har den tagit fram kandidatertill diken genom att vektorisera resultatet från en linjedetektering. Egenskaper-na för dikeskandidaterna har sedan beräknats genom en analys av höjdprofilerför varje enskild kandidat, där höjdprofilerna skapats utifrån ursprungliga data.Genom att filtrera kandidaterna efter deras egenskaper kan dikeskartor med an-vändarspecificerade mått på diken presenteras i ett vektorformat som underlättarvidare användning. Rapporten beskriver hur algoritmen har implementerats ochpresenterar också exempel på resultat.
Modellbaserad ekoföljning i vätskefyllda tankar
This thesis discusses model based tracking of radar echoes in tanks with liquid content. The errors in the measurements are not always random in these cases, and the interference that occurs when nearby echoes moves in relation to each other makes tracking difficult. The tracking problem can be broken down to four parts; track initiation, track destruction, association of the measured echoes to the tracks and to update the tracks with the associated echoes. The radar measurement is primarily made on the surface. However, additional echoes from the tank floor or other structures and double bounces are normally present.
Det redovisade resultatets värderelevans - före och efter IFRS
This thesis aims to investigate if there are any differences in the value relevance of yearly earnings announcements before (2000-2004) and after (2005-2009) IFRS were implemented for listed companies in the European Union. To assess the value relevance of earnings, an earnings response coefficient (ERC) is estimated using a linear OLS-regression model. The regression model uses accounting earnings per share as the explaining variable, with the corresponding return starting from (but not including) the previous year's earnings announcement date, ending at (and including) the current earnings announcement date, as the dependent variable. This study finds that there is no statistically significant difference between the estimated ERCs for the two periods. Although no statistically significant difference is found, data shows that the R2-values, which measure the explanatory power of the regressions, are higher for the period before IFRS.
Värdering av prestation och riskbeteende i ung ålder : Finns det ett samband?
This paper is a study how students at a high school in Falun, Sweden, estimates theirperformance in an upcoming math test which is then compared with the actual grade thestudent performed. The students who participated also answered questions related to ?risksituations? to examine whether there is a correlation between how students estimate theirperformance in the context and their risk behavior, and if the students act like economicmodels assume. In agreement with previous studies, the boys in the survey tended to beoverconfident in their performance. The girls in the study were neither over- norunderconfident in her performance and no significant difference in the estimation of one'sperformance between the sexes could be proven.
Skaftslamkrypa (Elatine hexandra) i Bolmen, utbredning, tillväxt, reproduktion och styrande faktorer
The plants in the genus Elatine are characteristic for oligo and mesotrophic lakes. This study focuses on Elatine hexandra one of the four species in Sweden. It is stated as vulnerable by the National Environment Agency and a conservation plan with guidelines to preserve the plant in Sweden is under preparation. There have been a few previous studies investigating this plant in other countries but this is the first one for Sweden. The aim of this study was to investigate the distribution, growth and reproduction of E.
The effects of Joint Ventures announcements on stock returns behaviour - An Event Study of the Stock Market
The purpose of this study is to examine the effects of joint venture announcements on stock prices behavior and simultaneously to test the German stock market (Frankfurter Wertpapierbörse) for efficiency. We tried not only to analyze the general impacts of a JV-announcement but also to look for differences in the market response to announcements of different types of joint ventures, namely: domestic, international, horizontal and vertical. Our expectations of efficient market were confirmed during our paper, which employed the technique of the standard event study. The calculation of abnormal returns which are the signals for market efficiency or inefficiency respectively were based on the market model, establishing linear relationship between the return on the market and the return on an individual security. The parameters of the model were obtained through regression analysis..
MEASUREMENT OF C-REACTIVE PROTEIN IN CANINE SERUM ON KONELABAUTOANALYZER 20
An inflammatory reaction is induced after release of proinflammatory mediators such asinterleukin 1 and 6 and tumour necrosis factor ?. These mediators stimulate the liver tosuppress the syntheses of albumin and endure the syntheses of acute phase protein forinstance C-reactive protein. The aim of this paper was to perform a method validation on animmune turbidimetric assay to quantify C-reactive protein in canine serum at the laboratory atSkara Animals Hospital, Skara, Sweden. The validation involved evaluation of the assaylinearity, precision, stability and recovery.The method was proved to be linear for both TruLab control and Medinor control.
Ekonomisk policy och tillväxt i en transitionskontext: en studie av realsocialistiska länder
Abstract During the last 15 years, the former ?really existing socialist? economies have undertaken an extensive transition process. In this paper the development, measured as GDP growth, is analyzed using variables for economic policy. The analysis is both theoretical, taking as starting point current positions in academia, and econometrical with the linear regression model. We show that while economic policy variables of inflation, economic freedom and institutional quality affect economic growth, the results are not only the ones predicted by the theory.
Informationsasymmetri och redovisning till verkligt värde - en studie av nordiska fastighetsföretag
This thesis aims to investigate the information effects of fair value accounting in Nordic real estate companies. As a consequence of the mandatory IFRS adoption in the European Union in 2005, listed Nordic companies are allowed to recognize investment property at fair value in accordance with IAS 40. Theory suggests that fair value accounting should lower information asymmetry. Therefore, this study aims to examine correlation between fair value accounting of investment property and information asymmetry on the stock market. To investigate this, we use bid-ask spread as a proxy for information asymmetry and examine Nordic real estate companies before and after the implementation of IFRS.
How streaming media can be used in commercial mass
distribution
Mass distribution with techniques as multicast and peer-to-peer are becoming increasingly important in the Internet. Today the distribution of sound and video over Internet, so called streaming media, is static due to the unicast method. This results in a linear increase of distribution costs and therefore no conditions for commercial scalability. This thesis describes why multicast may be the only scalable alternative for commercial mass distribution of streaming media over Internet. Mass distribution through peer-to-peer technology promises a lot but is fronting a couple of great challenges, for example asymmetric bandwidth, locality and legalization.

It describes a non-linear project based on a process-orientated theory called Theory-U by Otto C. Scharmer (2009). The project aims to investigate the changing conditions of Stage Theatre and deals with non-linearity as phenomena.
Vilsna tankar ? en studie i relationen mellan abstrakt och figurativ illustration
The reason for, and objective of, this project has been to research the relation between abstract and figurative illustration and how, if at all possible, one can bring them together and make them act as a whole.As a starting point for this project I used fragments from texts I?ve written during the past years. The texts deal with the thoughts and emotions that describe the state of melancholy or mania, two psychological conditions that are widely spread in our society. By illustrating these text passages in pencil drawings I?ve been given the possibility to investigate how to combine figurative illustration with the abstract alike.
Upplevelse av uppmuntran, självbild, människosyn och stress på arbetsplatsen
That we have a great need to be encouraged is coated in a variety of motivational theories. Despite our awareness of this need, studies show that Swedish employees feel a lack of encouragement in the workplace. The purpose of this report is to examine the factors that affect our ability to give others encouragement.Empirical data were collected through questionnaires from 91 people in the workplace. Correlation between the experience of giving and receiving encouragement, self-image, outlook on mankind and stress in the workplace are examined using a linear Multiple Regression Analysis. Correlation between the experience of giving and receiving encouragement is examined using Pearsons test of correlation.The results show that there is no significant correlation between the experience of giving and receiving encouragement, self-image, outlook on mankind and stress.
