Expert system to calculate the cofficient of friction : an approach to enhance traffic safety

Friction plays a key role in causing slipperiness as a low coefficient of friction on the road may result in slippery and hazardous conditions. Analyzing the strong relation between friction and accident risk on winter roads is a difficult task. Many weather forecasting organizations use a variety of standard and bespoke methods to predict the coefficient of friction on roads. This article proposes an approach to predict the extent of slipperiness by building and testing an expert system. It estimates the coefficient of friction on winter roads in the province of Dalarna, Sweden using the prevailing weather conditions as a basis. Weather data from the road weather information system, Sweden (RWIS) was used. The focus of the project was to use the expert system as a part of a major project in VITSA, within the domain of intelligent transport systems

Torrenting values, feelings and thoughts : cyber nursing and virtual self care in a breast augmentation forum

Earlier research shows that breast augmentation is positively correlated with positive psychological states. The aim of this study was to explore the shared values, feelings, and thoughts within the culture of breast enlargement among women visiting Internet-based forums when considering and/or undergoing esthetic plastic surgery. The study used a netnographic method for gathering and analyzing data. The findings show that the women used the Internet forum to provide emotional support to other women. Through electronic postings, they cared for and nursed each others’ anxiety and feelings throughout the whole process. Apart from the process, another central issue was that the women's relationships were frequently discussed; specifically their relationship to themselves, their environment, and with the surgeons. The findings suggest that Internet forums represent a channel through which posters can share values, feelings, and thoughts from the position of an agent of action as well as from a position as the object of action. These dual positions and the medium endow the women with a virtual nursing competence that would otherwise be unavailable. By introducing the concept of torrenting as a means of sharing important self-care information, the authors provide a concept that can be further explored in relation to post modern self-care strategies within contemporary nursing theories and practice.

Maskrosbarn : En litteraturstudie om barn i riskzon

Syftet med denna studie är att nå en djupare förståelse om hur samhället ska kunna stödja barn som växer upp under ogynnsamma förhållanden på ett bättre sätt. Studien baseras på en litteraturstudie på sex stycken självbiografier som valts ut efter vissa kriterier. Dessa självbiografier har sammanställts utifrån en kvalitativ innehållsanalys och ett antal teman som svarar på våra forskningsfrågor identifierades. Utifrån studiens syfte och frågeställningar har teorier om risk- och skyddsfaktorer, KASAM, skam, resiliens samt anknytning valts ut. Tidigare forskning visar på att utsatta barn och social barnavård är ett eftersatt forskningsområde. Vårt resultat av denna studie visar på brister inom såväl socialtjänsten som samhället i övrigt. Det finns ett omfattande behov av att ständigt uppmärksamma och tydliggöra vilket stöd dessa barn kan få.

DEN KOMMUNALA FÖRVALTNINGENSOM RATIONALISTISKT IDEAL- en fallstudie om styrning och handlingsutrymme inom skola,barnomsorg och miljö- och hälsoskydd

DEN KOMMUNALA FÖRVALTNINGEN SOM RATIONALISTISKT IDEAL - en fallstudie om styrning och handlingsutrymme inom skola, barnomsorg och miljö- och hälsoskydd.(The municipal authority as a rationalist ideal - a case-study on steering and scope for initiative within child-care, education and environmental departments.)A municipal authority is a considerable producer of services in the local community and iscommonly perceived as an important sector of the Swedish welfare system. One aspect of awell-functioning municipal organisation is that its administrative organs function efficiently.This study examines how activities in municipal administration are steered. The focus is on how different methods are used within a vertical hierarchical perspective to influence the actions of the participants and how the latter try to create space for action. To analyse the problem an ideal-type steering model is used.The study consists of three sections. In the first the research problem and the aims of the study are introduced as well as the methodological and theoretical approach. The result of the study is presented in the second section and in the third conclusions are drawn and discussed.The study shows that the perceptions of the participants involved regarding the possibilities of steering the everyday activities with the support of the methods studied differ on a number of points depending on the sector studied. When control of the various steering methods is distributed in different organisational units in the municipality a number of steering mechanisms operate side-by-side, sometimes in harmony and sometimes independently or in pure conflict with their goals. Steering leads to clear restrictions but there is clearlyroom for initiative, a ‘free-zone’ where the individual has room to act independently. Is it possible based on this study to state whether the ideal-type model functions in the way intended? On many accounts it would seem doubtful whether the effects of steering lead to beneficial effects for the activity. Rather it would seem that the effects of steeringsometimes function more or less randomly because the administration exists in a complexcontext in which the staff can be expected to have its own expectations and act in accordancewith them.
