Hur påverkas VD : ns belöningssystem av ägandet? ? en studie av svenska noterade bolag

There is a strong debate in the media about the CEO compensation in the listed companies and whether they deserve their high rewards. Many previous studies have shown differences in the reward system depending on the ownership structure, mostly testing for only ownership concentration or ownership category. This study aims to investigate how the influence of the owners affects the CEO reward system, testing for both the level and the structure of the reward. The sample used in the investigation is Swedish listed corporations and consists of 251 observations. A survey was also conducted but due to low response rate and because the answers are not representative for the whole sample the survey will only be used as an illustration.

Objektskoncentration vid slutavverkning

The study is made on behalf of SCA Skog Jämtlands förvaltning which is one of five administration units that SCA Skog consists of. The purpose of the study is to investigate which reduced expenses there are according to spatial concentration of cutting areas. By increasing the spatial concentration of cutting areas it will reduce the need of movements by trailer, also reduce the number of roads that you use during the activities. To be able to perform the study, access to a annual cuttings in nine years have been made available. From this volume new annual cuttings has been created but more concentrated. The two different results have been compared and the results show that concentration of cutting areas generates reduced need for trailer transports and less km road that has to be maintained. But then, if it´s practical viable can be discussed.

Siktning som saneringsmetod för metallförorenad mark

Toxic metals contaminate soil worldwide and thus serve as sever environmental threat. Therefore the purposes of this study were to investigate in which soil fractions that different heavy metals (Fe, As, Cu, Zn and Pb) could be found in contaminated soils and if it is possible to use sieving as a method for decontamination. Soil samples were collected from three different locations, the Nasa silver mine, the Blaiken-mine and Svalget environmental station. The samples were oven dried and later on sieved into six different fractions 8mm, 4 mm, 0.5 mm, 0.250mm, 0.063 mm and <0.063 mm. The fractions 4 mm, 0.5 mm and <0.063 mm from each location were analyzed in an x-ray fluorescence detector.

Aktivt ägande och lönsamhet i svenska företag

Active ownership is widely regarded as positive for the development and performance of businesses. In this paper, we investigate the impact of ownership concentration and owner identity on return on equity (ROE) in Swedish companies between 1986 and 2008, and show that active ownership might suffer from opposing effects. We find evidence, albeit weak, that ownership concentration has a positive effect on profitability, but that it levels off at high levels of ownership shares. Furthermore, we propose that family ownership has a negative effect on profitability. Our results are dependent of choice of statistical method, but show nonetheless a need to reevaluate what seems to be a universally positive view of active ownership..

Elementkoncentrationer i gran utmed en markfuktighetsgradient :

One key factor in silviculture today is sustainability. In order to achieve sustainability it may be important to restore lost nutrients to the forest after clearcutting. In order to calculate the removal, you need to know how much of different elements you will find in different tree compartments. The aim of this study was to investigate if the concentration of elements in different tree compartments of spruce (Picea abies (L.) Karst) were related to the moisture conditions of the site. Five plots at Risfallet (60º 21´ N, 16º 13´ E), was placed along a moisture gradient in a 40- year spruce stand.

Vertikal förtätning : En del av ett hållbart stadsbyggande?

This is an essay concerning the density of the city. An increasing amount of today?s cities have a shortage of space available for the erection of new buildings and settlements, especially in areas close to the city-centre. New buildings and settlements are therefore often found in the outskirts of the city, resulting in long distances between work and living for many people. These long distances are a waste of limited resources and are inconsistent with the vision of the sustainable city.The challenge for the future is to insert new buildings and settlements in the existing city-structure and in this way reduce the distances between different city-functions.The density of the city can be increased in two different ways; by inserting new buildings between existing ones or by extension existing buildings, for example by an additional floor.

Utveckling av ett provtagningssystem för alkohol och aldehyder i fordonsemissioner.

A system for sampling of alcohol and aldehyde from diluted exhaust gases from vehicles powered by ethanol has been developed and tested. The major part of the work has been research of earlier work in the field and the construction of the sampling system.The part of the system constructed for the measurement of alcohol has been shown to work, however, more test should be performed. The part of the system constructed for the measurement of aldehyde was tested parallel to a commercially available system, based on the same principle of measurement, and has been shown to work well.Determination of the concentration of gaseous ethanol using a FID has shown the since earlier known fact that a FID is not able to measure a correct concentration of ethanol. Furthermore it has been shown that high concentrations of gaseous ethanol can not be kept in a bag more than a few minutes without a substantial decrease of the measured concentration..

Betydelsen av fysisk aktivitet för barns koncentration i förskolan : En studie om betydelsen av fysisk aktivitet för barns koncentrationsförmåga vid samlingar i förskolan

The purpose of this investigation was to investigate how being outdoors and participating in physical activities affect the concentration in a collection situation among children.The methods I chose were observation of two groups of children two times each and interviews with four educators.The results showed that the concentration in the collected situation depends on past activity, where it has taken place and that the environment has an impact. If the previous activity been more active and physical the subsequent collected situation is calmer and the children more concentrate. The facts that the children have been outside in an inspiring environment that encourage playing and movement also have a position impact on the child´s ability to concentrate. The collected situation is an important moment in the preschool day when the kids need to congregate and get a chance for social interaction and a sense of togetherness with all the children and teachers. The conclusion is that there is a relationship between movement, physical activity and an increased concentration.

Fruktosamin som markör för diabetes mellitus hos katt :

Diabetes mellitus is characterised by persistent hyperglycemia in all species. Fructosamine is a glycated protein reflecting blood glucose concentration during the preceding weeks. It has become a valuable analysis to differentiate persistent hyperglycemia from transient stress induced hyperglycemia in cats. It is also used to evaluate current therapy in diabetic patients. Although fructosamine is a well accepted analysis, it is sometimes regarded with scepticism.

Barn med autism : En studie i hur skolarbetet kring barn med autism ser ut

This essay is about how working with children with autism works with the laws and regulations that fall under the Compulsory School Ordinance and Lgr11 (Compulsory for primary school, preschool classes and kindergarten). The aim of this work was to examine various educators thoughts, experiences and practices related to children with autism in primary school. The study is based on three questions: what kind of rights regarding support do children with autism have in the Swedish primary school, according to the primary regulation and Lgr11? How do the selected primary schools work with the support of children with the diagnosis of autism? And how well does the affected educator?s think that the support works?To answer these questions, four qualitative interviews with various educators, were made. My results show that all four educators believe that inclusive labor of children with autism is a good thing for everyone, as long as it is done properly and with the right order, so that the child with autism gets the opportunity to be part of a social group.

Lärande på hjärnans villkor : En fallstudie av ett antal klasslärares syn på begreppetarbetsminne och arbetsminnesträning

The study's purpose was to get a picture of what a number of class teachers know about and their views on the concept of working memory and working memory training and whether this affects their working and teaching in the classroom. The study is based on qualitative interviews and classroom observations and the theoretical perspectives that the study is based on two: didactic perspective and the socio-cultural perspective. The results of my study show that the class teachers' views and use of the concept of working memory is limited, even if they unknowingly working on parts of it in their teaching. All classroom teachers in my study term difficulties that can arise for students as concentration difficulties, which according to previous research can count towards deficiencies in working memory. All of the respondents in this study believe that it is mostly special education teacher who trains working memory, and that they themselves do not have that knowledge. They also believe that the classroom environment is important for all learning. Common to all respondents consider that the topic is important and would like to have more knowledge of how they can help and support pupils with poor working memory. As a special education teacher and teacher you often meet students who have trouble concentrating, and because of this may be difficult to absorb knowledge as when reading.

Flerspråkighet i förskolan : En kvalitativ undersökning om pedagogernas arbetssätt när det gäller språkligt heterogena grupper i förskolan

The purpose of my study was to visualize how teachers works with multilingual children in pre-school, the methods used to stimulate and develop primary and secondary language and how teachers does see second languages development with the help of the primary language. The study consists of qualitative methods in form of interviews which are made with four teachers who work within the pre-school. The findings during the collection of data (interviews) are going to be connected to the relevant literature on the subject I have chosen.The result showed that the concrete materials are used to stimulate and develop primary- as the secondary language and that the teachers have different opinions on secondary languages development with the help of primary language even if the primary language seems to be an important asset of all teachers that I interviewed..

Inkludering ? en studie om lärares syn på och erfarenheter av klassrummets mångfald

The aim with this thesis was to study how primary school teachers perceive their mission in working with inclusive education. The aim was also to study their thoughts and experience of the Special education support. To conduct the inquiry twelve primary school teachers from two different communities in Sweden were asked to give their views of inclusive education. The central issues was how the primary school teachers interprets the concept of inclusion, the opportunities and obstacles they perceived and how the Special education support was formed in the work with inclusion in their schools. The result shows that the majority part of the primary teachers interprets the concept as a spatial or social inclusion.

KRAV OCH MÖJLIGHETER FÖR STYRNING AV VATTENFALLS VATTENKRAFTSTATIONER

The secondary control must be part of the production plan, since the capacity will bedeployed in advance, just as the primary control. The activation of the new frequencycontrol should be preformed in Vattenfall's operations centers (DC) to minimizecommunication delay. Vattenfall needs to work towards a more holistic optimizationsystem. The main issue for Vattenfall Generation is not how we produce but ratherwhen, which is done with creation of bids. This is where there is the mostopportunity for improvement.

Spänningsanalys av axel-länkmekanism på borr-rigg

This master thesis is intended to give an increased understanding of the stress state in an axle, which is assembled in one of Atlas Copco?s mountain drilling rigs. The main problems investigated were how the axle is affected when the bearing is worn, when the pretension is varied, and how to dimension the axle. Answers to these questions were found by using hand calculations, practical testing and with Finite Element analyzes. The dimensioning of the axle is currently based on the bending stress, but the author?s opinion is that the axle should be dimensioned considering the equivalent stress.
