The overall aim of this study has been to come to a better understanding of what it means to be a Montessori teacher, by getting a group of Montessori teachers to reflect on their lives and work. Data exploration has comprised journals, interviews, written reflections and collaborative contextual analysis. Analysis of the teachers' occupational life histories and the findings as a whole have been

Patients who are incompetent need a surrogate decision maker to make treatment decisons on their behalf. One of the main ethical questions that arise in this context is what standard ought to govern such decision making. According to the Substituted Judgment Standard (SJS), a surrogate ought to make the decision that the patient would have made, had he or she been competent. Although this standard

Cavitation is a problem in many hydroelectric power plants since it can cause adverse effects on performance and damage to nearby solid surfaces. The concerns of this thesis are the numerical aspects of flow simulations in cavitating hydraulic turbines which contain several difficulties: turbulent and complex flows, steady and moving parts of the geometry, bubble transport and cavitation developme

In navigable waterways, owing to the relatively short fetches for wind wave generation, the free waves generated by moving vessels often produce the dominant wave action with respect to erosion of the shore. In response to the fairly recent introduction of high-speed ferries, combined with a planned expansion within the passenger- and car-carrying ship market, the need to model and predict coastli

An increasing number of market- and technology-driven software development companies face the challenge of managing several thousands of requirements written in natural language. The large number of requirements causes bottlenecks in the requirements management process and calls for increased efficiency in requirements engineering. This thesis presents results from empirical investigations of usi

Modeling and simulation are established techniques for solving design problems in a wide range of engineering disciplines today. Dedicated computer languages, such as Modelica, and efficient software tools are available. In this thesis, an extension of Modelica, Optimica, targeted at dynamic optimization of Modelica models is proposed. In order to demonstrate the Optimica extension, supporting sof

Aim of the study, background, theory and method The two aims of this study are to describe and analyse: i) how drug abusers have transformed their lives from the time when they did not use drugs, to becoming drug abusers, and finally leaving drugs behind them; and ii) what it means to be socially integrated with one's experience of having been a drug abuser. The women and men who participated in

This dissertation studies the problem of the inhuman in relation to human nature in philosophy from antiquity to the present, highlighting the interrelationship between science and philosophy in the development of concepts of monstrosity in France from mid-sixteenth century to late twentieth century thought. By means of constraint, it focuses on Ambroise Paré (1509/10–90) and Gilles Deleuze (1925–

This thesis consists of three papers in which different topics in spaces of analytic functions are considered. These papers are: I. "Estimates in Möbius Invariant Spaces of Analytic Functions." II. "Preduals of Q_p-spaces and Carleson Embeddings of Weighted Dirichlet Spaces." III. "On the Spectrum of the Cesàro Operator on Spaces of Analytic Functions." The first two papers are closely related

The intention of this dissertation is to provide a portrait of Hilding Rosenberg´s musical work "The Revelation of S:t John" (1940), for a large orchestra, chorus and recitation (recitative), through illuminating the work´s history of origin and basic literary and musical structure. As a composition initially intended for broadcast over the radio, the form and content of "The Revelation of S:t Joh

The emphasis on people-centred development is distinctive in today’s development discourse. This is noticeable in catchwords like democratic decentralisation, participation, and empowerment, which are highly esteemed among NGOs, donors, and policymakers in recipient countries. The benefits of participatory approaches are several. When people influence the process of development, policies and pro

The overall aims of this work were to investigate the consequences of hip disorders and hip osteoarthritis (OA) on health-related quality of life (HRQL) physical function and self-efficacy. The condition, hip OA, is often associated with significant pain and has a strong impact on physical function and quality of life. The prevalence of hip disorders were 32% and among the individuals reporting h

The present thesis is concerned with the development and application of a novel planar laser-induced fluorescence (PLIF) technique for temperature measurements in a variety of combusting flows. Accurate measurement of temperature is an essential task in combustion diagnostics, since temperature is one of the most fundamental quantities for the characterization of combustion processes. The techniqu

The sound absorption characteristics of resonant absorbers, implemented as perforated suspended inner ceilings attached with thin porous layers, are investigated. Several existing theories model the principal absorption mechanisms, but the interaction with the outer sound field influences the absorption in ways that can be modelled with new approaches. The effect of arranging the absorbing surfac

The present thesis describes development of a microdispenser-based technique to create of protein patterns for neurite guidance. The same technique was also developed to allow direct positioning of dissociated cells, including neurons, on cell culture substrates. Finally the role of galectin-3 and 8 during nerve regeneration was investigated. The thesis consists of four papers (I-IV). Microdispen

This thesis treats the development of Ion Beam Analysis (IBA) methods, principally for the analysis of light elements at a nuclear microprobe (NMP). The light elements are in this context defined as those with an atomic number Z of less than approximately 13 (aluminium). The work reported is to a large extent based upon multiparameter methods. Several signals are acquired simultaneously, and the d

IT has direct and observable positive effects for consumers. For firms, the situation is somewhat different, because efficiencies generated by publicly available technology tend to be competed away. Therefore, researchers from the strategy field and students of information systems have concluded that for firms, the opportunity lies in using IT better than competitors rather than in the technology

This thesis, which consists of three studies illustrating different angles of approach, discusses problems pertaining to accounting and allocation costs in municipal water and sewage enterprises. Water and sewage enterprises are financed by charges to users, and are generally run under the auspices of a municipal administration or within the framework of a municipal company. User fees are regulat

Membrane proteins are fairly refractory to digestion especially by trypsin. Less specific proteases like elastase and pepsin are much more effective. However database searching using non-tryptic peptides is much less effective due to the lack of charge localisation at the N- and C-termini and the absence of sequence specificity. We describe a method for N-terminal specific labelling of peptides fr

New information technology is developing faster than the models, metaphors and methods in use for conceptualizing the sharing and managing of information in organizations, in communities and in society in general. The way we utilize information technology today does not seem to succeed in supporting the everyday work practices through which organizations accomplish their work. In this Ph.D. disser
