Likviditetsva?gen till mer informerade investeringsbeslut : En studie om sambandet mellan a?garkoncentration och likviditet pa? Nasdaq OMX.

Abstract Master Thesis in Business Administration, School of Business and Economics at the Linnaeus University, 2013 Authors: William Funseth and Tobias Åkesson Supervisor: Magnus Willesson Examiner: Sven-Olof Yrjö Collin Title: The liquidity route to more informed investment decisions - A study on the relationship between concentration of ownership and liquidity on Nasdaq OMX. Background and problem: Previous studies have shown that liquidity can explain differences in returns in corporate shares, the company's cost of capital and the valuation of the company. Based on the effects of liquidity we developed a research question concerning how concentration of ownership effects liquidity of corporate shares the studies conducted for companies listed on Nasdaq OMX during a period with major changes on the stock market and is also investigating weather other company-specific differences can explain differences in liquidity. Purpose: The study's purpose is to study the relationship between ownership concentration and liquidity, and whether other factors might explain differences in liquidity. Method: The study is conducted with a quantitative method and it?s based on data collected from 2006-2011 for companies listed on Nasdaq OMX.

Rörelsens inverkan på barns inlärning : En studie om hur fysisk aktivitet påverkar barns inlärning utifrån ett fåtal lärare och elevers åsikter

The purpose of this investigation is to find out how the children?s exercises affect their learning capabilities. With exercise, I mean all kinds of movements, like physics, walks and games.The method I will use in this investigation is interviews, where I choose to interview both teachers and their pupils at a school which uses an exercise-program called röris. Röris is an exercise program which involves moving to music. I also choose to look at Bunkefloprojektet, were scientists has investigated how the power of concentration is affected by exercise.My conclusion from the interviews and the literature is that I can?t prove that the children?s exercises affect their learning capabilities.

REE-förande fosfater i Blötbergets apatitjärnmalm

The Blötberget deposit is situated in the north-western part of Bergslagen. The mineralization is an apatite-iron oxide ore of Kiruna type. In Bergslagen the apatite-iron oxide ores occur along a zone from Grängesberg through Blötberget to Idkerberget in the northeast and they represent the largest and the most important iron oxide deposit in Sweden, south of Norrbotten.Different REE hosting phosphate phases has been studied by optical microscopy and analyzed by EDS attached to an electron microscope.The key minerals other than iron oxides are apatite, monazite and xenotime. The relative concentration of the REE-bearing phases differs from the other apatite-iron oxide mineralizations in the area, for example Grängesberg, by a higher concentration of xenotime and lower contents of allanite..

ADHD och musik : Jobbar skolan med musik som inlärningmetod för barn med ADHD?

A pupil with ADHD is constantly getting new impulses and is unable to focus and remain concentration on their task at school. When the pupil loses concentration he or she can often be loud and thereby disturbing all the other pupils in the classroom. One of the reasons for losing their concentration is that these pupils got poor working memory. A recently study shows that working memory can be improved by playing and practice music.A theory that all people have a multiple intelligence that emerges from learning is a part of this study because school should encourage all children and ensure their individual learning. Multiple intelligences means that each person learns in different ways, for example through the musical intelligence that this essay partly focuses on.

Gärningsmannaprofilering : Ett fungerande verktyg eller påhittad filmglamour?

Some children develop externalizing and internalizing behavior problems at an early age. Previous research has often treated these children as a homogeneous group, the purpose of this study is to show that this group of children is in fact heterogeneous. Data from theSOFIAstudy was used and preschool pedagogues were informants. The sample contained 2121 boys and girls between 3-5 years. Groups of children with the behavior problems and the risk factors AD/HD symptoms, fearlessness and callous-unemotional traits were created.

Radioktivt cesium (Cs-137) i vildsvin (Sus scrofa) från Tjernobyldrabbade områden i Sverige

In April 1986 an accident occurred at the nuclear power station in Chernobyl. Radionuclides were spread all over Europe including Sweden. Today there are still measurable concentrations of 137Cs in the different ecosystems in the contaminated parts of Sweden. The wild boar is the second most popular game in Sweden and today the Swedish population consumes more wild boar meat than ever. As the wild boar population increases the wild boars are moving further north towards the contaminated areas, which creates an interest to study the state of 137Cs in wild boars in these areas. Muscle samples from wild boars collected during 2010-2013 were analyzed based on 137Cs content.

Koncentrisk hämning och stimulans av bakterietillväxt i agarkulturer

The aim of this study is to elucidate factors that effect growth of Sarcina lutea and Bacillus subtilis, exposed to the growth inhibitor SDS (Sodiumdodecylsulfat). Agar diffusion experiments revealed repeated, concentric zones of inhibition and stimulation upon exposure to Sodiumdodecylsulphate or to Amoxicillin. Temperature, nutrient concentration and inhibitor concentration were controlled. Formation of successively repeated zones of inhibition, stimulation, inhibition and stimulation is discussed: ? The extension of the primary inhibition zone is due to the concentration of applied Sodium dodecyl sulphate.? Immediately outside the primary inhibition zone the bacteria have access to diffusing nutrients that have not been consumed in the primary inhabitation zone.? In zones of dense bacterial growth the bacteria may produce inhibiting substances, affecting growth of bacteria in adjacent zones.? In zones of dense bacterial growth the nutrients will soon become depleted, thus affecting bacteria in adjacent zones..

Interpersonell problematik och arbetsallians i psykoterapi : Klientens upplevelse och förändring av interpersonell problematik och dess relation till arbetsallians i psykoterapi

The purpose of this study was to examine interpersonal problems and its relationship to the working alliance in psychotherapy. To examine this, data was used from Umeå and Lund University psychology practice client database, which clients responded to by using the self-assessment scales Inventory of Interpersonal Problems Circumplex Scales and the Working Alliance Inventory. The sample consisted of 201 participants that answered the questionnaires both before and after psychotherapy. A second sample consisted of 93 clients who specifically sought help for interpersonal problems. Results showed that the level of interpersonal problems before and after psychotherapy changes.

Sundbybergs stadsbibliotek. PR-arbete under åren 1954-1964.

The purpose of this master's thesis is to describe the expansion of Sundbyberg public library during the decade 1954 to 1964. Our focus of interest is the library?s concentration on public relations in 1954.During the experimental year 1954 a public relations librarian, Bianca Bianchini, was employed. Her task was to introduce thelibrary to the citizens of Sundyberg who were not already using it. As a background to this concentration on public relations we also describe the early development of the public library in Sundbyberg.

Blutsafts inverkan på blodets hemoglobinvärde

The aim of the study was to test whether or not menstruating women?s levels of haemoglobin changed after three weeks consumption of Blutsaft. Previous studies on nutrition supplements including iron have shown increased haemoglobin levels. On Blutsaft, however, there are no studies carried out and published. The participants in this pilot study were menstruating women, with haemoglobin levels between 105 and 125 g/l at the initial part of the study.

Utvärdering av avloppsvattenreningen vid Hallsta Pappersbruk : Kartläggning av inkommande avloppsvatten och optimering av driftparametrar

Hallsta paper mill uses large amounts of water during the pulp and paper making processes. The wastewater is treated in two separate activated sludge processes referred to as BIO 1 and BIO 2. The main aim is to reduce the organic substance content, measured as COD (Chemical Oxygen Demand) before the wastewater is released into the environment. Since the effluent produced is very rich in organic substances, the addition of nitrogen (N) and phosphorus (P) are necessary to give satisfactory treatment results. Problems with sludge bulking sometimes occur which lead to increased levels of suspended matter and nutrients in the effluent.

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).

Mångfaldens fiende Nr. 1 : En studie om 2010 års mediekoncentration och dess konsekvenser för samhället

Purpose: The essay was designed to examine what impact an increased media concentration in the provincial press may have on the society in the future. I also had the intention to create a greater understanding of the concept of media concentration and how the media groups relate to the public interest. Method: The work with this study was conducted by using methods from the qualitative methodological arsenal through interviews with, for the study, relevant informants, but also through a case report on the Stampen Group. The selection of informants had a background and a breadth which secured the credibility in this survey. The starting point was taken in previous research via a deductive approach where I tested how existing theories match reality. Conclusion: After completing this study should be noted that all respondents believe we will see a greater concentration of ownership in the Swedish media market in the future, and that it will reduce diversity. However, there are steps to take which I believe can work well in theory but perhaps not always in practice.

Direkta effekter av insekticiden deltametrin på zooplankton och bottenfauna : en fältstudie av bieffekter av insekticidinducerad eliminering av signalkräfta på Gotland

Direct effects of the insecticide deltamethrin on zooplankton and benthic invertebrates werestudied during an attempt to eradicate signal crayfish. In accordance with earlier studies theresults of this investigation showed that deltamethrin is highly toxic for arthropods, whileRotifera, Oligochaeta and Mollusca have a higher tolerance. This study concludes thatRotifera in treated ponds coped with the actual concentration of deltamethrin used during theeradication attempt but that they probably got a different abundance and changed compositiondue to a new situation in competition and predation. Crustacean zooplankton totallydisappeared, but approximately a month after the treatment they began to recolonise. All thetaxonomical groups of arthropods drastically decreased in abundance, with total eliminationof the most sensitive groups.
