The calibration theorem by Rabin [Rabin, M., 2000a. Risk aversion and expected utility theory: A calibration theorem. Econometrica 68, 1281-1292; Rabin, M., 2000b. Diminishing marginal utility of wealth cannot explain risk aversion. In: Kahneman, D., Tversky, A. (Eds.), Choices, Values and Frames. Cambridge University Press] implies that seemingly plausible small-stake choices under risk imply imp
A polyion-surfactant ion complex salt, cat-HECDS, has been synthesised, consisting of cationic hydroxyethyl cellulose w th dodecylsulfate counterions. Ternary phase diagrams have been established for aqueous mixtures of cat-HECDS with either the conventional surfactant NaDS or the polyelectrolyte cat-HECCl. Such mixtures represent the simplest possible aqueous mixtures of oppositely charged polyme
Cellulose, a polysaccharide consisting of beta-1,4-linked glucose, is the major component of plant cell walls and consequently one of the most abundant biopolymers on earth. Carbohydrate polymers such as cellulose are molecules with vast diversity in structure and function, and a multiplicity of hydrolases operating in concert are required for depolymerisation. The bacterium Rhodothermus marinus,
The present study deals with free play in preeschool. The purpose is to investigate the way children conceptualize play, and the significance of play in preeschool activities. The latter has been illuminated through an analysis of normative documents, and vatious methods have been worked out that show how the possibilities of play can be made use in preschool. Group interviews with children betwee
The purpose of this report is to design a thickness controller fo a hot rolling mill. The thickness control problem is difficult and small improvements make large savings possible. It is therefore relevant to use advanced control strategiesfor controlling the plate thickness. In the report a short introduction to the thickness control problem, and a description ofhow thickness control is done toda
Geographic accessibility to services is important. Having a grocery store and a school nearby are important living conditions and having a rescue station close by could be a life-saver. Costs for transportation are high and are predicted to increase, new environmental demands are being imposed on transportation and rationalizations are centralizing public and commercial services. These facts make
The nature of scientific research and the development of scientific software have similarities with processes that follow the agile manifesto: responsiveness to change and collaboration are of the utmost importance. But how well do current scientific software development processes match the practices found in agile development methods, and what are the effects of using agile practices in such proc
Popular Abstract in Swedish Det finns en skillnad mellan historia som vetenskap och historia som historiskt minne, som boken vill fästa uppmärksamhet på. Ådalen som motbild till det trygga Folkhemmet är en bild av hur vi kan uppleva verkligheten. Inte nödvändigtvis hur den såg ut. Vår uppfattning om vad som hänt kan vaa nog så verklig när vi handlar, agerar och tolkar omvärlden. Det är denna tolknThe prelude to this thesis is provided by the dramatic scenes that took place in Ådalen. During a demonstration, four men and one young woman were shot to death and five others injured by military troops ordered to Lunde harbour. Inspired by a number of other researchers (Koselleck, Samuel, Somers, Stråth, Södring, Jensen and Burke, to name a few), my investigation has analysed how the story of th
Disturbances in production caused by rupture, cracking and chipping of tool edges are only studied to a limited extent in comparison with the effect of the cutting edge wear. These phenomena are of increasing importance when automation in production is considered. This thesis deals mainly with the deterioration of cutting edges emanating from other sources than wear. By studying the non-wear-relat
Two separate topics in the area of colloidal chemistry have been investigated by the use of molecular modeling: the structural properties of polyion?macroion complexes and of diblock polyampholyte brushes. The main results were obtained by the use of Monte Carlo simulation in the framework of the primitive model, and in the case of polyampholyte brushes the simulation results were also complemente
Popular Abstract in Swedish Avhandlingen består av fem delarbeten. De första tre delarbetena består av 1) olika metoder att nå anhöriga till alkoholister för information om tillgängligt stöd, 2) könsskillnader hos partners till alkoholmissbrukare när det gäller psykiska symptom, upplevelser av utsatthet och copingstrategier när det gäller bemötandet av missbrukaren och i hanteringen av missbrukssiThis thesis concerns relatives of alcoholics. The aims were to investigate relatives’ situation concerning hardship, coping behaviour and psychiatric wellbeing. Two different information techniques (one standardized technique and one individually adjusted technique) were compared in order to reach relatives of alcoholics for information of available support. No significant differences were found i
Popular Abstract in Swedish Syftet med den här avhandlingen har varit att studera association och växelverkan mellan proteiner och polymerer. Två olika tekniker har använts i dessa studier; datorsimuleringar och fördelning i polymera vattenhaltiga tvåfassystem. Vikten av att studera protein-polymer-växelverkan ligger i att flera biotekniska, och medicinska tillämpningar baserar sig just på proteiThe aim of this thesis has been to study protein-polymer interaction and association. Two different techniques were used; Monte Carlo simulations were combined with partitioning in polymeric aqueous two-phase systems. Monte Carlo simulations have been used to evaluate the hydrophobic interaction in electrolyte solution. The results showed that monovalent salt only slightly increases the hydrophob
Reef biostromes and related facies from the upper part of Wenlock and from Ludlow were investigated in order to account for their formation, their palaeoecology and biology. In the Hemse Group of Ludlow age, all studied biostromes comprise a low diversity fauna where one or few species dominates. These biostromes are divided into Kuppen type biostromes, Grogarnshuvud type biostromes and Sjaustreha
Radio based localization is an active research topic with a wide range of applications. In this paper, we focus on localization of a radio receiver equipped with an inertial measurement unit. The localization is performed while simultaneously constructing a map of the small scale fading pattern in the local radio environment. The map in our case is a ray-trace-based multipath channel model. This s
Researchers studying individual variation in conspicuous skin coloration in primates have suggested that color indicates male quality. Although primate fur color can also be flamboyant, the potential condition dependence and thus signaling function of fur remains poorly studied. We studied sources of variation in sexually dichromatic facial hair coloration in red-fronted lemurs (Eulemur fulvus ruf
BACKGROUND: The orexins (hypocretins) are recently discovered hypothalamic peptides that are involved in the regulation of sleep, appetite and state of arousal. In the present study, we investigated the relationship between cerebrospinal fluid (CSF) orexin and specific psychiatric symptoms in suicidal patients. METHODS: A total of 101 patients were enrolled in the study shortly after a suicide att
Popular Abstract in Swedish Cykeln som transportmedel har många fördelar för individ och samhälle. Det är ett mycket energisnålt transportmedel, det förorenar inte, bullrar inte, tar liten plats och ger dem som cyklar välbefinnande och motion. Om fler cyklade istället för att åka bil skulle detta medföra trevligare stadsmiljöer. Ökad cykling hade också kunnat bidra till en ökad folkhälsa. För närThis work presents an evaluation of bicycle lane effects on cyclist safety and the ability of bicycles to compete with car traffic. Thirteen Swedish urban streets were studied before and after bicycle lanes were introduced. Data was collected using video recordings, speed studies, road side questionnaires/interviews with cyclists/car drivers, conflict studies and accident analysis. Results showed
Open Source receives high attention among organizations today, and there is also a growing interest on Open Source Enterprise Resource Planning (OS ERP) systems. Open source development is often considered having a high level of involvement from stakeholders in adopting organizations. However, it depends on for the first what is meant by stakeholders, but also what is meant by involvement. In the
Autologous hematopoietic stem cell transplantation (AHSCT) to treat multiple sclerosis (MS) has mostly been used in devastating cases as the last option to stop further neurological deterioration. However, evidence from several retrospective clinical trials indicates that young, less disabled patients with highly inflammatory active MS are the most likely to benefit from AHSCT, and after moving fr
