In the debate surrounding genetically modified (GM) food, intense controversies pertain over whether, or how, GM food products ought to be labelled. This paper examines how the GM-supportive and GM-sceptical alliances use arguments regarding labelling so as to strengthen their respective positions. It is an examination of conflicting arguments across social coalitions, corporations and policy-make
Popular Abstract in Swedish Giftiga alger - kan man äta sånt?! En sammanfattning på svenska Varje sommar varna's vi för giftiga algblomningar i media. Rapporterna brukar ofta handla om havet men många insjöar, speciellt i Skåne, drabba's också av massförekomst av alger. Det är framför allt cyanobakterier, eller blå-gröna alger som de kallade's innan, som blir så många att de helt dominerar algsaMass development of cyanobacteria (blue-green algae) is common in many lakes and coastal waters worldwide as a result of an increased nutrient loading. These blooms of cyanobacteria are undesirable for several reasons; thick mats of algae and unpleasant odour reduces the recreational values, bad taste reduces the quality of drinking water and the potent toxins produced by some species of cyanobact
Popular Abstract in Swedish QCD vid höga energier är fortfarande inte väl förstådd. Svårigheter uppkommer ifrån en starkt icke-linjär dynamik, samt från icke-störningsmässiga fenomen. Analytiska beräkningar är oftast möjliga enbart för enkla leksaksmodeller, eller för asymptotiska energier. I denna avhandling undersöker vi dynamiken i högenergiprocesser, med målet att finna en fungerande och realQCD at very high energies is still not very well understood. Difficulties arise from a strong non-linear dynamics and also from nonperturbative physics. Detailed analytic calculations are often only possible either for simple toy models, or for asymptotically high energies. In this thesis we investigate the high energy dynamics, with the goal of finding a realistic, working model for high energy Q
Bluetooth is currently emerging as one of the most promising personal wireless network technologies. It is primarily designed as a cable replacement between for example a cell phone and a PDA. However the price/performance level also makes it a promising technology outside the office. The automation industry is currently showing interest in using Bluetooth for more industrial applications. However
A specific pull-out test used to determine in-situ concrete compressive strength is analyzed. This test consists of a steel disc that is extracted from the structure. The finite element analysis considers cracking as well as strain hardening and softening in the pre- and post-failure region, respectively. The aim is to attain a clear insight into structural behavior. Special attention is given to
In order to reduce the environmental impacts within the building sector, recycling of building materials is on the increase. Projects are carried out on several levels and are often well analysed regarding the economic consequences; however, the actual environmental effects are rarely studied. This paper presents a study of the environmental impacts due to a building from 1997 with a large proport
Temporary agency work has come to the fore during recent years as the phenomenon in itself has become more frequent on many national labour markets. This thesis examines how, by means of labour law and collective bargaining, the balance between, on the one hand, the employers’ need for flexibility, and on the other hand, the work-force’s need for stability and continuity in the form of income and
The purpose of this chapter is to identify a number of significant contemporary changes in the "old" diplomacy, associated with the Westphalian system of sovereign states, and to address the question of how thoroughgoing these changes may be. Specifically, it discusses three aspects of change: technological developments, the emergence of new types of actors in the international arena, and the chan

Popular Abstract in English This work is focused on two accident types: accidents between motorized vehicles and pedestrians, and accidents between motorized vehicles and bicyclists. It aims at better understanding how the number of accidents is related to the number of road users; and how the speed at the site and age of the victim is related to how severe the injuries are. The work relies on sevThe aims of this work are to better understand (1) the relation between exposure and the risk of an accident between pedestrians and motorized vehicles and between bicyclists and motorized vehicles occurring at urban intersections and (2) how the speed environment and the victim´s age relate to the injury severity/outcome once a pedestrian or a bicyclist has been struck by a motorized vehicle.
