Popular Abstract in Swedish I avhandlingen försöker jag visa hur polis, socialtjänst, rättsväsen, massmedia, olika intressegrupper, allmänhet och inte minst ungdomar själva skapar föreställningar om vad som är ett ungdomsproblem. De rutiner som de olika organisationernas aktörer utvecklar och det sätt som ungdomar och vi övriga "pratar" om ungdomsproblem bidrar till att den framställda bilden som The main aim of my dissertation is to investigate som conceptions, power relations, and practices in the discourse of youth problems. I have studied some of the actors that are involved in the social constructing of the "juvenile delinquent" such as the police, the judical system, the social service, the media, the general public and last but not least, the young people themselves. The bulk of my

Gaussian Mixture Model (GMM)-based vector quantization of Line Spectral Frequencies (LSFs) has gained wide acceptance in speech coding. In predictive coding of LSFs, the GMM approach utilizing Kalman filtering principles to account for quantization noise has been shown to perform better than a baseline GMM Recursive Coder approaches for both clean and packet loss conditions at roughly the same com

Popular Abstract in Swedish Chefer ägnar större delen av sin arbetstid – ca 80 procent - till att kommunicera med andra människor. Kommunikation har alltid haft en central roll i ledarskapet, men i dagens organisationer har kommunikationen blivit ännu viktigare och också svårare. Strävan efter delaktighet, delegering, arbete i nätverk och tvärfunktionella team innebär att kommunikationen mellan chThe focus of this dissertation is communication between managers and subordinates in a modern organization. The research questions are concerned with ideas, practices and organizational conditions in relation to leadership communication. My starting point for this study was the change in leadership philosophy that was introduced in many organizations at the beginning of the 1980s. This transforma

The glycaemic index (GI) concept was originally introduced to classify different sources of carbohydrate (CHO)-rich foods, usually having an energy content of > 80 % from CHO, to their effect on post-meal glycaemia. It was assumed to apply to foods that primarily deliver available CHO, causing hyperglycaemia. Low-GI foods were classified as being digested and absorbed slowly and high-GI foods as b

The utilization of CO2 in various products and services must be carefully assessed in order to achieve reduced CO2 emissions and simultaneously to add to the net economic benefit of society. In this paper, a framework for the assessment of CO2 utilization options in the chemical industry is outlined in which the total CO2 emission is estimated in four steps. First, the processes under study are su

This paper presents a study where a market-driven requirements management process is simulated. In market-driven software development, generic software packages are released to a market with many customers. New requirements are continuously issued, and the objective of the requirements management process is to elicit, manage, and prioritize the requirements. In the presented study, a specific requ

As the ‘third wave’ progressed it has been argued that democratisation should be analysed in terms of partial regimes rather than with multidimensional concepts of democracy. This article analyses the democratic qualities of one such partial regime, albeit arguably the core dimension of representative democracy: multiparty elections. The analysis focuses on the three basic democratic values of ele

We show that the relation of second order stochastic dominance, which has found widespread use in models of economic behavior under uncertainty, may be described in terms of conditional expectation. If a distribution G second order stochastically dominates another distribution F, then there are random variables g and f with distributions G and F, respectively, such that g can be obtained from f by

Free radicals have been suggested to play a role in the development of diabetic retinopathy. The aim of the present study was to examine whether the metabolic perturbations caused by high-fat feeding of two strains of mice, the C57BL6/J mice and the NMRI mice, interfere with one of the free radical enzyme defense systems in the retina, i. e., glutathione (GSH), and whether morphological changes oc
