Variable incomes and under-investment due to risks of economic loss is an often overlooked aspect of poverty. Affordable insurance against risks such as loss of harvest due to low rainfall may be a key factor in reducing poverty. This study aims to examine the relationship between microinsurance against weather-related risks and levels of investment among covered farmers. The analysis is done by r

Previous research has shown the significance of syndicated loans as an alternative financing source to corporate bonds. This thesis investigates the influence of the financial development of a country on specific syndicated loan terms. Our estimates show that country level dimensions such as banking stability, the efficiency of financial institutions and their depth play a limited economic role in

Inom matematiken finns något som kallas ringar. En ring är en mängd element i vilken man också har definierat de två operationerna addition och multiplikation. Elementen kan vara av olika slag. Det som krävs är att ett antal regler, så kallade axiom, ska också vara uppfyllda i mängden. Dessa axiom ska gälla för att en mängd R ska vara en ring: Om a och b är element i R så är a+b och ab också eleThe main focus of this thesis is Wedderburn's theorem that a finite division ring is a field. We present two proofs of this. The thesis also contains a proof of a theorem of Jacobson and a proof of a generalisation by Artin and Zorn that a finite alternative ring is associative, and therefore a field.

The purpose of this report is to evaluate and assess the fire safety at the sports center Pilängshallen located in Lomma. The report is only focused on personal safety and no consideration has been taken concerning economic or environmental damage. Pilängshallen is used on a daily basis for several different sport and workout activities by both local sport clubs and the public, as well as by scho

Money is often left on the table when corporations issue new securities. Explanations for the underpricing phenomenon are often related to information asymmetry between the investor and the issuer. In this study we investigate factors affecting underpricing on corporate bonds in the Swedish market. To some extent contrary to what was expected, the results indicate that bonds are on average overpri

The purpose of this thesis is to investigate whether factor augmented vectorautoregression (FAVAR) models estimated using principal component analysis are able to improve monthly inflation rate forecasts for Sweden. We produce 42 forecasts for the period January 2012 to June 2015 and evaluate the forecasts by their root mean square errors as well as their ability to correctly predict the sign of t

The aim of this study was to examine social workers perceptions of medication assisted treatment. We have made a qualitative interview study in which we interviewed seven municipal social workers that have knowledge and experience of working with people who have substance abuse problems and medication assisted treatment. We found that the social workers are describing both advantages and disadvant

This thesis investigates the phenomenon of personal branding on social media and, in particular, it examines how successful YouTubers create and build their personal brand via content. The thesis provides valuable input to the existing literature on personal branding, which is predominantly found in self-help books and articles by self-proclaimed gurus within personal branding. Using the method of

Den här uppsatsen undersöker de avancerade metoder av effektivt innovationsskydd under företagskoncentrationsprövningar som finns i USA och EU. Syftet är att finna synergier mellan dessa två system och föreslå nödvändiga förbättringar av det europeiska systemet genom att introducera innovation som en reell standard för prövning, inkludera dynamisk effektivitet, omstörtande innovation och icke-prisThis thesis analyses advanced methods of effective protection of innovation in merger control in the USA and in the EU, finds synergies between the systems and suggests the necessary improvements of the European system of merger control in high technology markets: introduction of innovation as a real antitrust standard, inclusion of dynamic efficiencies, disruptive innovations and non-price consid

The Swedish Confederation of Trade Unions (LO) presented a new political report in 2015 with the purpose of renewing the wage policy of solidarity. The aim with a renewed wage policy is to create full employment instead of the present mass unemployment, to decrease the wage gap and to eliminate wagedrifts. The renewal may seem a bit strange, when the original policy (also called the Rehn-Meidner m

Sjötelegrafen Köpcentrum is a shopping mall located in Nynäshamn, Sweden. To examine the evacuation conditions in case of fire at Sjötelegrafen, a fire safety evaluation has been conducted. The report presents two dimensioning fire scenarios that are seen as representative for the shopping mall, these are fire in ICA Maxi and fire in Jysk. These different main scenarios were analyzed and simulated

The Jacobian-free Newton–Krylov (JFNK) method is designed to solve a linear system of equations that appears in Newton’s method. It uses the generalized minimal residual (GMRES) method to solve the linear system and a simple function to approximate the matrix-vector multiplications required in GMRES. An advantage of GMRES is the ability to check the residual of a potential solution without doing a

Since the rise of the Islamic State the world has seen a proliferation of public executions in which spectacle and theatricality have come to play an important role. Their propaganda has adopted an aesthetic style in which violence is openly displayed, celebrated and glorified. This thesis explores the role that aesthetics has in the performed and mediated execution videos of the Islamic State, by

Denna studie ämnar undersöka hur konsumentmotståndet mot modeföretaget American Apparel konstrueras samt hur konsumentens identitet formas i relation till detta motstånd. Studien utförs genom Faircloughs kritiska diskursanalys för att synliggöra de diskurser som ligger till grund för studiens analys och slutsatser. Empirin består av intervjuer och virtuella observationer som genom tematisering visThis study aims to investigate how consumer resistance towards the fashion company American Apparel is structured, and how the identity of the consumer is formed in relation to this very resistance. The study is performed by Fairclough’s critical discourse analysis to reveal the discourses forming the basis of the analysis and the conclusion of this study. The empirics consist of interviews and vi

Detta är den populärvetenskapliga sammanfattningen av masteruppsatsen ”Designing and Maximizing Switch-Mode Efficiency of MODPSU, the Modular Power Supply”. Den sammanfattar teoretiska studier och resultat från mätningsexperiment som genomförts i syfte att minimera totala förluster för DC/DC-switchade nätaggregat.This work is an investigation into practical design and loss minimization of DC/DC-switched power supplies, enabling cooler operation, smaller size, and additional or wider areas of use. There is an abundance of switch controller ICs on the market and a few of the manufacturers offer very sophisticated design tools that suggest operating parameters and grade components. However, one of the major

The purpose of this thesis is to question and discuss whether the complication of power-relations created upon the present surface of the human body can be surpassed, by re-conceiving the body and ultimately leaving the body behind, without the loss of Being, through the critique of art and photography. This overall query has been broken down into three questions. (1)‘Does the solution behind the

This work investigates visualizations of two crises; terrorism and climate change. Focus lies on mediated images concerning Paris 2015, where terrorist attacks had an impact on the following UN climate change conference (COP21). The symbol of the Eiffel Tower was used to portrait both issues and will be studied through a semiotic analysis. Terrorism and climate change are argued to be interlinked,

Surveillance cameras are vital in the nuclear power industry where the reactor equipment must constantly be kept under surveillance to maintain safety. Constant monitoring is however difficult due to the highly radioactive environment, which cause cameras to malfunction and eventually break. Malfunction typically manifests itself as quality degradation of the image from the cameras. Initially, tem
