In many biomedical contexts, e. g. when evaluating hearing disorders, the data obtained can be described as pairs (x1, y1), …, (xn, yn) where x is a quantitative variable and y a 0/1 variable whose probability of taking the value 1 is a monotonic function of x. One way of analysing such data is to perform probit regression; thereby two parameters, b0 (= the constant) and b1 (= the slope) are estim

The objective of this thesis was firstly to examine the possibilities of creating a universal tool for evaluating IT-security. When all the material was gathered we saw that we had strayed away from our subject and that our focus was on IT-threats and IT-professionals apprehensions and possibilities on the subject. The purpose of this thesis was there after to find and identify threats and counter

Standardsystem är något som är mycket vanligt hos företag idag. Det är många som implementerar sådana system för att effektivisera sin verksamhet. När verksamheten hos ett företag förändras eller om verksamheten skiljer sig något från andra uppstår vissa problem med standarder i system. I det läget kan det bli nödvändigt att vidareutveckla ett standardsystem för att det ska passa just det företage

The flat tax rate is increasingly under scrutiny in West European countries as a model for taxation. Progressive taxation might be deemed as unsatisfactory to attract investment in the 21st century in a world of more global competition. Using macroeconomic data, this paper investigates whether the Baltic flat tax countries in Europe have higher growth rates than other transition economies. The fin

This essay uses the Factor Augmented Vector Autoregressive (FAVAR) approach to quantify the effects of monetary policy. Traditional methods to estimate the effects of monetary policy, such as Vector Autoregressive (VAR) models, have yielded unsatisfactory results, mainly due to sparse information sets included in the models. Augmenting the VAR model with factors summarizing the information of a va

Systems development methods mirror different organizational perspectives, and not all methods are formalised, but what they have in common is the purpose of structuring and supporting systems development processes. Which method would be the most suitable may be determined by the systems development context at hand, because every systems development context is unique. Information is a valuable asse

China has had an unbelievable economic development over the last 25 years. Their gross domestic product (GDP) has increased by more than 9% yearly. Since the middle of the 1980’s this trend has become more and more dependent on China’s private firms. China’s private firms are much more effective than their counterpart state-owned enterprises. Despite this fact, private firms are still treated very

This thesis is the result of a case study which has its starting point in the fact that mergers and acquisitions are characterized by a high level of risk and often fail to reach stated goals such as leverage of synergy, many times due to the inability of integrating the concerned organization’s information systems. Existing problem perspectives do not include what could be a factor contributing t

Increased global trade in high-value food products presents new possibilities to developing countries to increase export revenues from agro-food trade. Yet, it also poses new challenges upon these countries to comply with prevailing food safety standards on industrial markets. Increased wealth in industrial countries and a number of severe food safety scandals have jointly contributed to an increa

Under tidigt 80-tal växte olika sorter av kommunikationsmodeller fram, bland annat Daft och Lengels, Media Richness Theory. Denna teori var baserad på den tidens kommunikationsmönster. Idag nästan 20 år senare har vi sett explosionsartad IT-utveckling vilket har medfört förändringar i det dagliga kommunikationsmönstret. I denna uppsats undersöker vi om Media Richness Theory fungerar på ny teknik m

Det finns fyra huvudsakliga orsaker till genusskillnader. Jag har valt att främst undersöka hur dessa påverkar utbildning, hälsa och arbetskraft i Ghana. Genom att samla statistik över dessa tre indikatorer för både män och kvinnor vid olika årtal har jag gjort observationer.

This paper examines the increasing use of bilateral investment treaties as instruments of foreign investment protection. The outcomes of treaty arbitrations are analysed to assess the extent to which treaties limit the economic policy choices available to host states. The disputes are also analysed to determine how such treaties may affect the development of legal institutions and the general appl

In May 2004 eight former communist countries (EU-8) with close historical trade ties to Russia joined the European Union. According to integration theory, we expect that Russia – a so called third country – in some cases may suffer from trade diversion due to this. This thesis focuses on the possible effects on Russian trade resulting from the 2004 eastern enlargement of the European Union. It aim

Vatten är inte en vanlig vara och bör därför inte heller betraktas som en sådan. Dess avgörande egenskaper och svåra hantering gör att kraven på välfungerande institutioner är stora, men gör också den ekonomiska analysen mer komplicerad. Traditionella, ekonomiska lösningar på externaliteter och effektivitetsproblem går inte alltid att ena med de rättvise- och moralaspekter som uppkommer när det ha

Uppsatsen behandlar frågan om huruvida högre takt i produktivitetsutvecklingen påverkar sysselsättningsgraden negativt i en ekonomi då förbättringar i arbetsbesparande teknologi medför lägre efterfrågan på arbete. Frågeställningen har uppkommit med jämna mellanrum genom historien sedan den första industriella revolutionen utan att något långsiktigt samband kunnat bekräftas. Uppsatsens undersökning

From the early 1990s and onwards the use of debt relief as a method of providing development assistance has become increasingly popular, especially since the launch of the HIPC initiative in 1996. This thesis aims to investigate the general theoretical and empirical support of the growth enhancing properties of debt relief with regard to low income countries. Focus is put on evaluating the harmful

Organizations’ external environment is full of business ventures. Individuals play ‘in role’ and ‘extra role’ at the same time within the organizations. They are also located in an online environment where they participate and communicate using online social tools. Moreover, individuals within organizations seldom know who are likely to provide the right information or knowledge. The "who kno

The aim of this thesis is to uncover the determining factors behind the feminisation of the Swedish bank sector 1910-1939, through analysis of time-series and the Union periodical Bankvärlden. Economic and institutional explanations are tried, from a structural-analytical and gender perspective. The results show that feminisation was most rapid during the 1910’s, driven by a strong demand for labo

Vi undersöker den ickeparametriska optionsprissättningsmodellen med namnet kanonisk värdering. Vi visar att den kanoniska modellen fungerar väl på svensk data. Vi visar också att kanonisk värdering kan generera ett volatilitetsleende som stämmer överens med det vi observerar på marknaden. Dessa empiriska resultat är konsistenta med tidigare forskning. Ett teoretiskt motiverat resultat är att den k

Sammanfattning Denna uppsats utreder sambandet mellan privatiseringsreform av vattendistribution och det teoretiska begreppet ojämlikhetsfällan. En ojämlikhetsfälla är ett tillstånd av relativ brist på tillgångar och möjligheter, skapat och bevarat av en snedvriden institutionell miljö. Vår frågeställning är huruvida ojämlikhetsfällan som fenomen består efter en genomgripande privatiseringsreform.
