What affects Hiv in South Africa's different provinces? This thesis examines if education, unemployment rate, GDP per capita, and the literacy rate has any relationship with the Hiv prevalence. This is analyzed using theory and data in the form of a simple microeconomic model and an econometric regression analysis based on cross sectional data of the provinces of South Africa. The regression analysis shows that unemployment rate and education have significant effects of the Hiv prevalence in South Africa. The microeconomic model in the thesis indicates that when education is higher, individuals are more aware that the probability of being infected by Hiv is higher when the Hiv prevalence is high.

This study investigates whether auditors affect the tendency to report correct taxes for small companies. Since November 2010 the smallest companies in Sweden are no longer obliged by law to have an appointed auditor to perform the former yearly audit. The auditor shall during the audit, amongst other tasks, investigate whether the audited companies follow Swedish law, and report them if they do not. The presence of the auditor might influence the actions of companies to act according to law, and reduce errors in the reporting. Errors regarding tax reporting will result in a revised tax decision if detected by The Swedish Tax Agency.

Denna uppsats behandlar de relativa prisökningar som skett för snusprodukter i Sverige och vill undersöka om dessa har lett till minskad efterfrågan som nationalekonomisk teori föreslår. Utifrån teori och tidigare forskning har en efterfrågemodell konstruerats för att möjliggöra en statistik undersökning.Variablerna som ingår i modellen är inhämtade från Statistiska centralbyråns prisenhet och Swedish Match AB och inkluderar prisuppgifter för varor, försäljningsstatistik och disponibel inkomst under tidsperioden 1999-2009.Resultaten från regressionsanalyser för tidsseriedata visar på att de ökade priserna har haft en negativ inverkan på efterfrågan på snus under den gällande tidsperioden, men att denna effekt varit förhållandevis liten..

Syftet med denna litteraturstudie var att beskriva människors upplevelse av att leva med multiple skleros. Artikelurvalet baserades på och utfördes via databaserna Medline, Cinahl och Academic search.

This thesis aims to investigate if there are any differences in the value relevance of yearly earnings announcements before (2000-2004) and after (2005-2009) IFRS were implemented for listed companies in the European Union. To assess the value relevance of earnings, an earnings response coefficient (ERC) is estimated using a linear OLS-regression model. The regression model uses accounting earnings per share as the explaining variable, with the corresponding return starting from (but not including) the previous year's earnings announcement date, ending at (and including) the current earnings announcement date, as the dependent variable. This study finds that there is no statistically significant difference between the estimated ERCs for the two periods. Although no statistically significant difference is found, data shows that the R2-values, which measure the explanatory power of the regressions, are higher for the period before IFRS.

 This paper is made on behalf of Statistics and Research Åland, ÅSUB. The aim is to explain the turnover for companies in Åland, with appropriate variables. The main study variables are variables that consist of the Swedish and Finnish activity indices. The study variables also include variables which consist of tourists from Sweden and Finland and the introduction of the Euro in Finland. The data used is from the period January 1996 to June 2008.Different regression models for the turnover are tried and explanatory variables are selected by use of stepwise regression, backward elemination and forward selection. The final model includes activity indices for Sweden and Finland, the introduction of the Euro, tourists from Finland and an autoregressive component of order one .

Multiple sclerosis (MS) is one of our most common neurological diseases. The development of the disease often make the affected persons live with it for a long time. There are two types of the disease, the first is a progressive type and the other is relapsing remitting. Strengthening exercises isn?t commonly used as a treatment method although muscle weakness and fatigue are common symptoms.

Tidigare forskning har genom att studera alla tillgängliga företag eller företag medudda branscher exkluderade identifierat vissa nyckeltal som bra indikatorer påfinansiell kris. I denna studie undersöks om dessa nyckeltal även ger ettsamstämmigt resultat för en udda bransch. Med utgångspunkt frånbioteknikbranschen identifieras genom logistisk regression nyckeltalen korta skuldergenom eget kapital och avkastning på investerat kapital som indikatorer på finansiell kris.Avkastning på investerat kapital överensstämmer med tidigare resultat, medan kortaskulder genom eget kapital bör, för denna bransch, tolkas tvärt emot jämfört medtidigare studier..

Objective: In recent years there has been an increasing interest within the clinical (medical) science in measuring people?s health. When estimating quality of life, present practise is to use the EQ-5D questionnaire and an index which weighs the different questions. The question is what happens if the individuals estimate there own health, would it differ from the public preferences? The aim is to make a new prediction model based on the opinion of patients and compare it to the present model based on public preferences.Method: A sample of 362 patients with unstable coronary artery disease from the Frisc II trial, valued their quality of life in the acute phase and after 3, 6 and 12 months.

The aim of this paper is to analyze aid, grouped into sectors, and its effect on growth in developing countries, to find out which type of aid has had the most positive effect on growth. We compiled a regression analysis based on panel data over 81 developing countries from 1975-1999. In our first regression we considered and group countries by institutional quality, in the other we considered and group countries after regional differences. As a measure on institutional quality we used the KKZ-index. The principal aim of this paper was to find out what kind of aid is the most efficient in its influence on growth in LDC?s.

In 2022, Russia completed its full-scale invasion of Ukraine. The EU responded with powerful restrictive measures against Russia to demonstrate its unified support for Ukraine, indicating that the perception of Russia as an external threat to the EU, particularly in Central and Eastern Europe (CEE), has become increasingly evident following the invasion. Drawing on theory and previous research suggesting that external threats strengthen group identities, I argue that Russia is perceived as an external threat to EU identity in CEE after Russia's invasion of Ukraine. Stephan and Stephan's integrated threat theory considers an external threat as either realistic, posing a threat to the ingroup's existence, or symbolic, posing a threat to the ingroup's worldview. The purpose of this study is to examine the relationship between EU identity and the perception of Russia as a group threat to the EU among individuals in CEE based on the nature of the group threat: realistic and symbolic.

På sistone har allt mer kritik riktats mot forskning inom klassificering. Trots att forskningen har resulterat i en uppsjö av klassificeringsmetoder finns det de som menar att den har varit ett misslyckande och pekar på det faktum att ingen klassificeringsmetod anses vara systematiskt bättre än den andra eller ens rena gissningar. Detta leder till att valet av klassificeringsmetod i många fall vilar på individuella preferenser snarare än på vetenskaplig grund. Enligt litteraturen bottnar detta faktum i ett underliggande samband mellan det optimala valet av klassificeringsmetod och egenskaperna som karaktäriserar datamaterialet.Uppsatsen tar avstamp från denna problematik och syftar till att undersöka kopplingen mellan det optimala valet av klassificeringsmetod och datamaterialets egenskaper. Denna intention uppnår vi genom att tillämpa logistisk regression, elastic net och boosting tillämpat på klassificeringsträd på sex verkliga datamaterial med varierande statistiska egenskaper.Resultatet visar att den relativa klassificeringsförmågan varierar med datamaterialen.

Purpose: We have three purposes that will answer our problem questions. Our first purpose is to identify how diversification effects for investors changed between emerging markets and developed markets in the period 1996-2010. Our second purpose is to examine the two crises, IT and financial crisis, and if the correlations between these two crises have changed. Our third purpose is to examine to what extent the Swedish stock market was influenced by other markets in the period 1996-2010, the IT and financial crisis.Methodology: The method is based on an analytic model consisting of two tools; Regression- and Correlation analysis. The Regression analysis will be used when investigating if a change in a foreign stock market affects a change on the Swedish stock market.

Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. The CDMA technology was first introduced in the second generation?s cellular systems but has since then been improved and is reused in today?s 3G systems as Wideband CDMA.

The Swedish Transport Administration has, and manages, a database containing information of the status of road condition on all paved and governmental operated Swedish roads. The purpose of the database is to support the Pavement Management System (PMS). The PMS is used to identify sections of roads where there is a need for treatment, how to allocate resources and to get a general picture of the state of the road network condition. All major treatments should be reported which has not always been done.The road condition is measured using a number of indicators on e.g. the roads unevenness.
