Föreliggande studies syfte var att undersöka validitet och intern konsistens för den svenska översättningen av Impaired control scale (ICS), en självskattningsskala som mäter grad av kontroll av alkoholkonsumtion. ICS består av subskalorna; Attempt control (AC), Failed control (FC) samt Predicted control (PC). Svar på ICS sammanställdes från respondenter (n = 203) som behandlats för alkoholproblem vid mottagningar i Västra Götaland. Faktoranalysen visade en bakomliggande faktor för AC, och två faktorer för FC respektive PC. Den interna konsistensen var god.

Olika modeller har genom aren tagits fram för att förenkla analys av aktiemarknaden. En relativt ny teknik är så kallade artificiella neuronnät. Dessa modeller har visat sig lovande när det gäller att förutsägaaktiekurser. Projektets syfte är att hitta artificiella neuronnät som gerbra förutsägelser av framtida aktiekurser. Under projektet har ett mjukvarusystemsom genererar och tränar artificiella neuronn at av typen feedforwardutvecklats för att kunna testa neuronnät med olika indata, struktur och träningsinställningar.

Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.

The aim of this thesis is to find a statistical model that sort logs according to a Predicted modulus of elasticity on the sawn boards. The input parameters for the model are X-ray variables from an X-ray scanner. For some of the log classes sawn at the sawmill it is desirable to have a narrow distribution of modulus of elasticity on the sawn boards. 250 pine logs from five different diameter classes were numbered and followed through the sawmill process. Log data were collected from X-ray and 3-D scanners in the log intake.

The mission was to create a prototype of a menu system for the companySystem Andersson AB. The instructions were that it has to be as interesting andmodern now as in 20 years. We had to look at technology from the cutting edgeof development to make our prototype survive in the future. WindowsPresentation Foundation (WPF) was the technique we focused on. There areonly a few applications that take advantage of WPF today, but it is Predictedthat WPF will be the next generation method for developing applications to theWindows platform.To make our menu visually appealing, easy to use and at the same timefunctional, we followed the clear path and guidelines that are available ininteraction design.

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Abstract During the last 15 years, the former ?really existing socialist? economies have undertaken an extensive transition process. In this paper the development, measured as GDP growth, is analyzed using variables for economic policy. The analysis is both theoretical, taking as starting point current positions in academia, and econometrical with the linear regression model. We show that while economic policy variables of inflation, economic freedom and institutional quality affect economic growth, the results are not only the ones Predicted by the theory.

Can degree of degenerative brain disease be Predicted with the help of measurements of cognitive deterioration?Alzheimer?s disease progresses through nerve cell break down in the brain and the simultaneous deterioration of the individual?s cognitive function. This disease is common among elderly persons. This thesis examines if the level of deterioration of cognitive function is associated with different biochemical and clinical markers for degenerative brain diseases. In addition, this thesis examines if the level of decline in cognitive functions vary between groups with different levels of degenerative brain disease.

Zero knowledge protocols is a lesser known type of protocol that can be used for identification. These protocols are especially designed not to reveal any information during an identification process that can be misused later on, neither by the one who should be convinced of the identity of the user, nor by anyone else that is eavesdropping. Many of these protocols are also especially designed for implementation in smart cards. The more common type of card with a magnetic stripe has during the last few years become more susceptible to attacks since they are easily copied. Smart cards combined with a secure identification protocol has been Predicted to be the solution to this problem.

The aim of this study was to investigate people?s ability to detect deception and if variables such as birth order, personality and suspiciousness affect this ability. The study was conducted at Växjö University with students as participants (n = 278). A film of two people arguing both for and against their own personal opinions was constructed and participants assessed credibility on a categorical scale (Honest/Dishonest). Neither birth order nor level of suspiciousness revealed significant differences as pertains to credibility attribution.

The aim of this study was to examine differences in the experience of intrinsic work-motivation and to examine changes depending on profession, where the purchasers experienced a higher level of individual demands and control than the production leaders. Another purpose was to see how the intrinsic motivation needs Predicted mental well-being in the professions. The study was carried out using an internet survey that was distributed by e-mail, there were 98 participants. Two questionnaires were used; Basic Need at Work scale (W-BNS) measured intrinsic motivation and GHQ12 measured mental well-being. The result showed that the staff overall had high intrinsic motivation with highest scores on relatedness followed by competence and lastly autonomy.

This master thesis concerns the relation between law and the theory of the conceptual metaphor which has developed within cognitive linguistics. Although its main focus is abstract thinking, it also covers a wide range of aspects within cognitive linguistics, such as the prototype theory and radial categories. In order to address this relation, three questions will be dealt with. Firstly, does the theory of the conceptual metaphor have relevance to interpretation of legal rules and contracts? Secondly, can the same theory explain why a legal rule or a contractual term has been interpreted outside of its most given area of application? Thirdly, when an interpretation is not predictable from a legal viewpoint, can such an explanation answer to that fact? Answering the first question will require a descriptive analysis of the conceptual metaphor and cognitive linguistics.
