Decision support systems (DSS) are widely used in both public and private sectors. The objective of our research is to provide knowledge about the actual use and impact of DSS in police organizations. The system that is evaluated in this study is a DSS, recently developed and implemented in the Police organization in Skåne. There is hardly any evaluation done on these systems when used in this par
Uppsatsen behandlar faktorer att ta i beaktande vid val av tekniker för hantering av användarkrav, med särskilt fokus på utveckling för webben. Som ett medel för detta tas ett ramverksutkast fram, där teori om kravhantering, användarmedverkan, teknikkategorisering och värdering, samt organisation integreras. Ramverket prövas empiriskt genom intervjuer med åtta utvecklare på fyra medelstora till st
Due to the increase in file-sharing in later years, there is a wide concern among music industry professionals and others that the music supply will be negatively affected by the decreasing sales of pre-recorded music. However, almost no research effort has been put into measuring the change in the supply of music. Using two indicators of music supply, this paper investigates how the supply from i
In this paper, we investigate how important a firm’s proximity to the industry debt ratio is to its stock price performance. To achieve this goal, event study methodology is applied on stock price reactions upon the announcement of seasoned equity offerings. Depending on whether the offering moves the debt ratio of the firms “closer to” or “away from” the industry median leverage ratio, the averag
Uppsatsen diskuterar äldre gifta pars pensionsbeteende i Sverige. En diskret durationsmodell tillämpas på kvinnans pensionering, med mannens pensionering som ett tidsvarierande kovariat. Det visar sig att mannens pensionering har en signifikant och starkt positiv effekt på kvinnans utflöde till pension. Däremot har varken egen- eller korsekonomiska variabler signifikant effekt; kvinnans egen hälsa
I uppsatsen görs en jämförelse mellan undantag från den börsrättsliga likhetsprincipen i dagens Takeover-regler och i förslaget till nya Takeover-regler. Eftersom det som är nytt i förslaget inom dessa ramar handlar om hur prisdifferens mellan A- och B-aktier ska hanteras är analysen också genomförd med detta i fokus. Förslaget till nya Takeover-regler innebär utan tvekan en skärpning av den börsr
I denna uppsats diskuteras risken för marknadsmisslyckande vid etisk offentlig upphandling i Sverige, dvs. upphandling i vilken krav ställs på att grundläggande mänskliga rättigheter efterlevs i produktionen av de varor som upphandlas. Eftersom upphandlande enheter har små möjligheter att observera att kraven efterlevs, är sannolikheten stor att producenter fuskar. Denna uppsats försöker med hjälp
Kuwait överkonsumerar vatten och elektrisk energi och förbrukar cirka 2/3 mer än jämförande länder i Europa. Den främsta anledningen är de så kallade perversa subsidier på dessa varor, vilka är närapå gratis och konsumeras utan mätning eller debitering efter förbrukning. Varorna framställs genom förbränning av olja och importerad gas i en relativt ineffektiv process och sammantaget är denna konsum
The essay applies the methodology put forward in Baur (2003) with some modifications and extensions in order to investigate on contagion and spillover effects originating from the financial sector in European and U.S. equity markets during the crisis following the “dot-com” bubble in 2000-2003 and the financial crisis of 2007-2009. A clear distinction between spillover and contagion effects is dra
The purpose of the thesis is to retrieve the correlation between treasury securities of different maturities and the stock market and find significant variables to explain this relationship. Correlation time series were retrieved and used as dependent variables in a multivariate regression in order to find significant explanatory variables. The theory includes prior research done on the relationsh
Shortly after the start of the transition from planned to market economy in Central and Eastern Europe and the former Soviet Union, an overall drastic fertility decrease began in all the countries of this region. This thesis focuses on the theoretical and empirical connection between transition and fertility. With the use of Gary Becker´s New Home Economics as a theoretical framework, fertility d
This paper examines the interactions among the three stock markets of the US, Germany and Turkey by applying Vector Autoregressive Model (VAR). Besides causality, impulse response and variance decomposition analyses are done. One of the main findings is that between the US and German stock markets information is transmitted fast and they are quite well integrated. Another result is that, as expect
The purpose of this thesis is to investigate if it is meaningful to use a portfolio strategy that minimizes the portfolio risk every day, when the investment horizon is 10 years. To minimize the portfolio risk a EWMA (Exponentially Weighted Moving Average) method is used to calculate the conditional variance-covariance matrix. This matrix is used to calculate the portfolio weight that minimizes th
This study analyzes the impact of socioeconomic and cultural variables on marital fertility for Switzerland in the period comprising 1870 – 1930. Using panel data techniques the analysis shows that variables measuring industrialization had an impact in declining fertility as well as cultural variables such as religion and language.
The purpose of this thesis is to criticize the Commission’s approach to the application of Article 82 to the exclusionary abuses of the dominant firms. It is a very interesting and hot topic as the attitude of the Commission and the European Courts have many implications on the consumer welfare and total efficiency in common market and innovation capacity and the economic development of the Europe
Energy is an important component in production. Today, energy comes from mainly non-renewable resources such as petrol and coal, which carry with them negative externalities on climate, which in turn affects human life and long term growth. To prevent this climate change the utilization of these resources needs to be reduced. This can be done by replacing non-renewable resources with renewable res
Gains from health improvements for the worst-off in society should be weighted according to their possibility to achieve a fair inning. This statement parts from the fair inning equity definition developed by Williams (1997). A fair inning is the level of full health all individuals should be entitle with. It is the aim of this paper to assess immigrants and natives health disparities under the li
This study aims to analyze the development in the rice market in the EU15 during the period 1990-2007. During this time the common agriculture policy (CAP) has been subject to some major reforms, leading to a significant decrease in the level of import tariffs and intervention prices and the introduction of the decoupled system of single farm payments. The effects of the reforms are discussed, but
EMU har idag pågått i tio år och många länder vill ta del av dess fördelar. I den stundande krisen anser många att Sverige bör ansöka om medlemskap medan andra menar att Sverige bör avstå. Genom Sveriges deprecierande valuta ökar exporten och därmed ökar Sveriges inkomst. Förlorar man denna inkomst vid ett medlemskap i EMU? Dagens diskussion får oss att fundera över hur ett EMU-medlemskap påverkar
In this thesis, the focus lies on the determinants of changes in credit ratings. Multiple regression is used to study the relation between credit ratings and a quantity of selected economic variables. The study is restricted to the US market and the ratings have been assigned by Moody’s during the period 1999-2008. In line with previous studies, the short-term interest rate and corporate profits a
