The 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.
Denna studie ämnar öka förståelsen för hur content marketing och relationsskapande kan ges uttryck i digital kommunikationen mellan ett tjänsteföretag och dess kunder. Studien är av kvalitativ fallstudiekaraktär och det empiriska underlaget består av inlägg publicerade på fallorganisationen Avanza Banks sociala mediekanaler samt delar av företagets hemsida. Materialet har analyserats ur ett sändar
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-pris
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 vis
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
The present paper aims to analyze the impact of eleven macroeconomic factors and the one-month lagged stock return on the performance of ten sectors within the United States. The set of potential factors is based on previous research as well as published methodologies of credit rating agencies. It includes the one-month lagged stock return, earnings per capita, consumer price index, private consum
Bakgrund: Vårdskador är ett globalt problem inom hälso- och sjukvården. Rapportering av avvikande vårdskador är av stor betydelse för patientsäkerhetsarbetet att förbättra kvalitet och säkerhet i vården. Syfte: Syftet var att undersöka antalet avvikelser som rapporterats, samt fördelningen mellan avvikelser rapporterade från operations- och anestesisjuksköterskor vid ett regionsjukhus under de sen
