Handel med utsläppsrätter inom EU - Möjlighet eller papperstiger

This study in Environmental Science examines the amendment of the EU-Directive on. Greenhouse gas emission allowance trading. The Directive is to be considered as a tool for fulfilling the obligations that the Union and its member countries have taken on through the 1997 Kyoto agreement together with the protocols proposed at that time. The flexible mechanisms of the protocol are intended as instruments for limiting the climatic changes arising from anthropogenic sources, emission allowance trading being one of these mechanisms. The results presented here consist primarily of an analysis of interviews with various experts in the field of emission control concerning the possibilities and problems attending the process of implementation.

Blood compatibility of biomaterials made of recombinant spider silk

Native spider silk is an attractive lightweight natural polymeric material with a unique combination of strength, extendibility and flexibility. Synthetic, recombinant spider silk is an attractive biomaterial with several possible fields of application. When a foreign material is introduced to blood, this can for example cause unwanted coagulation and complement activation. The aim of this study was to investigate if coatings of heparin or albumin could improve the blood compatibility of films of recombinant spider silk and to develop an initial method to do so. Hypothetically, objects like pacemakers, stents and dental implants could be covered with spider silk films of high blood compatibility to reduce potentially harmful foreign body reactions caused by the immune defense. Increased blood compatibility would likely lead to improvements for both the individual patients and the society thanks to reduced load on healthcare institutions. Our objective was to assess the blood compatibility of both functionalized and non-functionalized recombinant spider silk by evaluating coagulation and activation of the complement system of the immune defense. Coagulation was evaluated visually on glass slides and complement activation was analyzed by measuring the concentration of the complement system mediator C3a in blood samples that had been exposed to the different materials. This study introduces a non-toxic and easy performed method of improving the blood compatibility of recombinant spider silk films by adding a heparin coating. Heparin coated surfaces had statistically significantly higher blood compatibility than uncoated surfaces. The effects of albumin coating of films were less clear compared to the results of heparin coated films. Complement activation could not be evaluated because of high activation in all samples prior contact with the materials that were included in the study..

Är ökad pressfrihet dåliga nyheter för korruption? - En kvantitativ dataanalys som testar styrkan i sambandet mellan pressfrihet och korruption.

This paper aims to broaden the discussion on how press freedom can be a powerful tool in the war on corruption. Previous studies have shown a significant relationship between more press freedom and less corruption, it also shows that the causal link runs from press freedom to corruption and not the other way around. There are quite a few studies on the impact of a free press on corruption and therefore there is a lot more to be published on this issue.This paper looks at press freedom as one of the most important parts of a democratic society and that it plays a vital role in reducing corruption as both an informant on key issues and also as a ?watchdog? on society. But press freedom cannot be seen as an ?easy fix? in a country or the international community's struggle to reduce corruption.

Politiskt förtryck: orsaksförklaringar, mekanismer och uttryck : Rohingyafolket som Agambens homo sacer i kontrast till Kymlickas liberaldemokratiska perspektiv

The persecution of the Rohingya Muslim minority population in southwestern Burma has come to the fore in recent years. The aim of this study is to first analyse the degree and respects of biopolitical control in the case of political oppression. Secondly, the aim is to compare the similarities and differences when it comes to the causes, mechanisms and expressions of the two theoretical starting points in the case.Giorgio Agamben´s biopolitical theory, which tries to reconnect state control over life and death with modernity, forms the basis of the analysis. Will Kymlicka´s liberal theory on minority rights serves as a theoretical comparison tool. Methodological starting points to the specific bilateral purpose will be both of the textual and discursive analytical tradition.

Plant defensive mechanisms against insect pests

This study has focused on testing the following two hypotheses:? Pest resistant plants have higher levels and/or several different kinds of secondary metabolites. ? Induced defensive systems in resistant plants are activated more rapidly than those of susceptible plants. As a background for the test of the hypotheses a short literature study was performed concerning plant defensive mechanisms in Arabidopsis thaliana.

Styrning i fotbollsorganisationer - byråkrati, klan eller marknad?

Nowadays the world of football has become more commercial than before. As a result of this the clubs' financial status is getting more and more important. Therefore the UEFA has given the national federations a specific task to make sure that the clubs from each country follow certain standards of maintaining the football credibility. The Swedish federation has decided that the Swedish clubs must follow the so-called ?elitlicensen?.

Bioelectromagnetics for improved crop productivity : an introductory review with pilot study of pre-sowing treatment of tomato

Various electromagnetic (EM) treatments has been investigated for their potential in improving crop productivity over the past century. There is today an increasing amount of scientists advocating EM treatments as an organically compatible method for improving plant growth and yield. However, failure to produce repeatable effects and defining causal mechanisms has made it a study of much controversy and debate. The subject requires indepth interdisciplinary knowledge, making it inaccessible for the majority of biologists, horticulturists and growers. In this combined literature review and pilot study, these issues are addressed by providing a comprehensive introductory review of the topic plant bioelectromagnetics and its potential horticultural usability.

Kampsport som verktyg inom socialt arbete

Studien söker svar kring hur undervisning i kampsport upplevs av vuxna kvinnor och om kampsportsträning kan ha en relevans för socialt arbete för kvinnor som målgrupp. Studien undersöker vilka val som gjorts av kvinnorna i samband med att de valde att börja träna kampsport och vilka upplevda effekter de har lagt märke att träningen leder till för deras egen del. Slutligen diskuteras vilka sociala verksamheter som kan tänkas ha nytta av kampsportsträning i sin verksamhet och vilka överväganden som då bör beaktas..

Ett litet ord med stora implikationer : En studie om förståelsen kring ordet Gay i allmänt negativ bemärkelse

Many of us have grown up hearing or using words meant as insults or negative adjectives that were in fact names for social groups. Most of them have gone unquestioned in the mainstream consciousness, but the term Gay in the generally negative meaning has in the past years been given attention as offensive and homophobic, with debates emerging in response over whether or not this is true, particularly on the internet. It is the articles and forum threads from these debates that make out the empirical material for a qualitative study as I ask what these people?s thoughts are about this term and how it is perceived.After a qualitative coding and analysis of these texts, and interpretation of the results based on Erving Goffman?s theory of Phantom acceptance and stigma terms, Judith Butler?s theory of performativity, Ferdinand de Sassure?s theory of signifier and signified and how it connects to the community and Baudrillards theory of simulacra, this is the principal conclusion that I have drawn:For some of the people in this debate, the term Gay and its use is about homophobia and heterosexism, though mostly it?s not overt but a subconscious part of the continued dehumanization and stigmatization of homo- and bisexual people. This is a position I callThe socially focused skepticism.

SKOTTSTÄLLNING AV ÖVNINGSVAPEN TILL GRANATGEVÄR CARL GUSTAF

Att be om hjälp utan att fråga

This report is our Master thesis. Our work has taken place at a one-stop-shop in Sölvesborg during the spring of 2002. We have conducted ethnographical studies concerning the one-stop-shops frontdesk and telephone exchange. During these studies we became aware of some differences under which the daily work was to be carried out. When operating the switchboard the staff usually work alone and perform the tasks individually.

Psykologiska mekanismer och miljöperspektivet : sambandet mellan attityder och beteendeintentioner inför samhällets miljöpåverkan

Syftet med studien var att pröva vilka psykologiska mekanismer som påverkar sambandet mellan attityder och beteendeintentioner inför miljöpåverkan hos individer i konsumtionssamhället. Hypotesen var att det finns ett miljömedvetande hos människan, men att det är en skillnad mellan attityd och beteendeintention. Även emotioner inför miljöpåverkan hos deltagarna undersöktes, för att fördjupa studien. Undersökningen har gjorts kvantitativt via en webbaserad enkät, genom utskick via Facebook till vuxna individer i Sverige mellan 18-65 år (N=49). Svarsprocenten var 46 procent.

Grooming : Ur ett socialpsykologiskt perspektiv

The purpose of this essay is to analyse the descriptions of young girls' experiences of internet contacts, which have led up to sexual abuse. The aim is to give additional understanding and knowledge concerning grooming.       Grooming means that somebody gets in contact with someone else with the intention of committing sexual violations at a later stage. In most cases this concerns adults who contact children. We have chosen to confine ourselves to focusing on the grooming on internet that has happened to girls. By means of thematic analyses of texts from the books Jag kände mig speciell, grooming på internet, 2012 and Alexandramannen, vår tids största nätsexhärva, 2009, we have found certain themes and linked them up with previous research-work and also theory of social psychology.

Finally, suggestions have been designed in CATIA V5 and prototypes were produced using 3d-printing.

NBF- Förmågan att se på andra sidan kullen eller ?Kejsarens nya kläder"

So- called ?Network Based Defense? (NBD) was introduced in Sweden in connection with the transformation of the Swedish Armed Forces in 1999. NBD is based on the U.S. variant Network Centric Warfare (NCW), which in turn is derived from research on the concept of Revolution in Military Affairs (RMA). In Sweden the concept was introduced and included not only the Armed Forces but was intended to also support the Swedish civilian agencies in order to create networks and hence share the available information and thus more effective crisis management and to provide more "bang for the buck." In developing the concept of NBD the Swedish Armed Forces used both economic and human resources, in the form of research, new technologies, new organization and new methods.Between year 2004 and 2006 the Armed Forces once again entered the process of reorganization.
