Att vara partner eller kontrollant. En studie av Sidas uppföljningskrav:
External forces have significant impact on organisations. This study analyzes the implications of one type of external forces in aid-focused NGOs through two qualitative case studies where it is investigated if Sida?s reporting requirements have the intended effects: learning and control using a theoretical framework where it is recognised that the requirements may also result in dysfunctional behaviour: decoupling and colonisation. The study shows that when the demands are the result of institutional pressure rather than an ambition to generate learning and control, the demands tend to be unrealistic and the NGOs therefore decouple the formal fulfilment of the demands from the actual activities. It is argued that a partnership, which incorporates trust and dialogue, is a prerequisite, not only for learning, but also control.

Tyst Motarbete? : En studie om kvinnor i styrelsen påverkar avkastning på kapitalet.
ABSTRACTTitle: The exact title used in the thesis will be mentioned here.Level: Bachelor thesis in BusinessAuthor: Mattias Lindqvist & Jonas TesfaySupervisor: Peter LindbergDate: 2011 ? JuneAim: In Sweden the representation of women on company boards is discussed extensively. It has also been suggested that regulations such as quotas should be imposed, in hopes of getting the gender balance on the board of directors. Measures such as these have been presented when this problem attacks our democratic values about how a society should look like. The aim is to study and analyze whether there is any connection between the return on assets and the proportion of women on company boards.Method: The paper is made from a quantitative with a deductive approach.
Sjuksköterskors uppfattning av elektronisk dokumentation avseende tidsåtgång, teknik och vårdkvalitet
Documentation in electronic journals is perceived as time consuming and sometimes technically difficult to handle, but also leads to an improved quality of care. Objective: The purpose of this study was to investigate nurses' perceptions of documentation with a focus on timing, technique and quality of care and whether any differences in these perceptions were dependent on age. Method: Quantitative descriptive cross-sectional study in the survey form, 28 nurses at a university hospital in central Sweden participated in the study. Regression analysis was performed with Spearman's rank correlation coefficient. Results: Electronic documentation takes 30 to 60 minutes for most nurses and half of them considered it a reasonable time.
Påverkar olika faktorer bilföretagen? : ? Hur påverkar ett högt oljepris, miljömedvetna marknader och ekonomiska trender bilföretagen?
The automotive industry is today in a world of globalisation and external factors can influence the car companies and it is important that they progress with the people. When an external factor, as the oil price, increases dramatically, it will affect the economies in different matters. Other external factors are impacted by the oil price, for example inflation, unemployment and target rates. In addition, people are changing their preferences due to the attention of the environment. With this as the foundation the problem of the essay were divided into three aspects.
Hur står sig Modigliani och Millers teori om kapitalstruktur under hög- kontra lågkonjunkturer? : en studie av 30 börsnoterade bolag på den svenska marknaden
Problem formulation: This paper will examine how the capital structure of firms affects their market valuation by applying the Modigliani-Miller theory on Swedish listed companies in a boom and a recession. The study will examine whether it is possible to draw any conclusions as to whether companies with high debt to equity ratios are valued lower in a recession, in comparison to companies with low debt to equity ratios.Purpose: To empirically test the Modigliani-Miller theory of capital structure in a boom and a recession in order to see if the companies? market value is affected differently depending on whether they have a high or a low debt to equity ratios.Methodology: The essay has a deductive and a quantitative methodological approach. Data analysis was done through a correlation analysis, a regression analysis and a hypothesis testing.Theory: The Modigliani-Miller theory of capital structure with taxes states that companies with a high debt to equity ratios has a higher value. One of the risks with a high level of debt could be that during a financial downturn companies have more difficulty realizing capital and are thus more likely to go bankrupt.Conclusions: The study shows results that are contrary to the Modigliani-Miller's theory; all the correlation analyses between debt to equity ratios and market value are negative.

Studiemotivation en jämförelse mellan gymnasieelevers egen uppfattning om motivationsnivå och Self-Determination Theory : en jämförelse mellan gymnasieelevers egen uppfattning om motivationsnivå och Self-Determination Theory
Studien handlar om svenska gymnasieelevers motivation för att studera matematikämnet. Den teoretiska grunden hämtas ifrån Self-Determination Theory (Deci & Ryan, 1985). Studiens syfte är att undersöka hur väl gymnasieelevers egen uppfattning om sin motivationsnivå kan prediceras genom de fyra ingående motivationsorienteringarna i Self-Determination Theory: (1) external regulation; (2) introjected regulation; (3) identified regulation; och (4) intrinsic motivation. Deltagarna (n = 132), 44 pojkar, 84 flickor och fyra som valde att inte specificera kön, studerar vid två gymnasieskolor i Falu kommun. Deltagarna fick via en webbsida besvara en enkät som mätte variablerna: upplevd motivationsnivå, external regulation, introjected regulation, identified regulation och intrinsic motivation.
Röstpremien - premien för aktiens rösträtt
This thesis aims to investigate the voting premium for companies differentiating voting rights between share classes on the Stockholm Stock Exchange. The voting premium represents the value of a vote attached to the share. The voting premium can be estimated from the price premium between two listed share classes with differentiated voting rights. Rydqvist's dissertation (1987) serves as a model for this study which investigates whether the theory of the so called "oceanic games", along with a proxy variable for cost of control, can predict the voting premium during 2010-2012. To the original model developed by Rydqvist, control variables for differences in liquidity between share classes are added to investigate for an increase in the explanatory power.
Samband på individnivå mellan akuta klövskador och cellhalten i mjölk hos mjölkkor :
The purpose of the present study was to investigate the cow-level association between acute hoof lesions and the somatic milk cell count in dairy cattle. Cows from three loose-housed Swedish dairy herds were enrolled in the study if they had an acute hoof lesion treated by a veterinarian or professional hoof trimmer during the preceding year, according to farmer records. Studied lesions were sole ulcer, dermatitis, interdigital necrobacillosis and hoof abscess, in each case causing lameness. For each hoof-diseased cow, 0 to 3 healthy cows were included, matched with respect to herd, breed, parity and lactation stage. Cell counts were obtained from monthly test recordings from one month before to three months after the hoof-lesion diagnosis, and log-transformed.
Kalibrering av den multivariata variabeln trädslagsfördelning
Den multivariata variabeln trädslagsfördelning beskriver volymsförhållandet mellan
tall, gran och löv i ett skogsbestånd. Ofta är variabeln skattad med subjektiva metoder
vilket resulterar i två typer av fel, systematiska och slumpmässiga.
Subjektivt värde = Sant värde + systematiskt fel + slumpmässigt fel
De slumpmässiga felen är omöjliga att justera, men de systematiska går att åtgärda
genom kalibrering.
Målet med arbetet har varit att finna lämpliga metoder att kalibrera trädslags
fördelningen i subjektivt skattade register för att eliminera det systematiska felet.
Kalibreringar har gjorts med fyra olika regressionsmodeller och ett neuralt nätverk.
Tillit eller politiska åsikter : Vad som styr kommunala chefstjänstemäns beteenden, prestation och engagemang på arbetet
Syftet med föreliggande uppsats är att undersöka om kommunala chefstjänstemän som delar politisk åsikt med kommunens styrande politiker i högre utsträckning än andra chefer också ?gör det lilla extra? på arbetet. Syftet är även att se om det är tillit till de styrande politikerna snarare än politiska åsikter som är viktigast för att förklara benägenheten att göra det lilla extra på arbetet. Detta undersöks genom att studera beteenden, prestation och engagemang på arbetet. Urvalet bestod av chefen för utbildningsförvaltningen (eller motsvarande) i Sveriges samtliga kommuner och undersökningen baserades på data insamlat med hjälp av webenkäter under hösten 2014.
Internetbedrägerier ? utsatthet och den upplevdasäkerheten vid internetanvändning bland studenter

Energisäkerheten för fjärrvärmeanläggningars bränsletillförsel i Mälardalsområdet
There are several energy systems in the Swedish society and to ensure the comfort and health of the citizens it is of importance that the different energy systems are functioning properly. District heating is one of these energy systems and many household depend only on district heating to warm up their homes.
District heating is dependent on several processes where every step needs to function in order to deliver the produced heat to the end consumer. Previous studies have investigated the distribution of district heating and how to make customers choose district heating as their heating method. The supply of fuel to the district heating plant has not been studied as much, even though it is an important part of the whole system. This thesis is a part of the project NORD-STAR (Nordic Strategic Adaption
Research), which has focused on climate adaption in the Nordic countries.
