Sammanfattning Provokativa åtgärder är en effektiv metod som polisen främst använder vid grov organiserad brottslighet. Det finns flera olika varianter av provokativa åtgärder, dock ingen så omdiskuterad som brottsprovokation. Otillbörlig brottsprovokation innebär att en polis eller en privatperson, som på uppdrag av polisen, har provocerat fram ett brott av gärningsmannen som denne utan polisens Summary Provocative action is an effective policing method used against serious organized criminal activity. There are several variations of provocative action, however, none as controversial as entrapment. Entrapment is considered to have occurred when a Police Officer, or a private person acting on behalf of the police, incites the committing of an offence that the offender otherwise would not h

This thesis is about how railway maintenance should be performed according to science and examine if these theories are complied in practice.

Abstract Many species have genetic sex determination and sex chromosomes that differ in size between males and females. This heteromorphy in sex chromosomes has evolved due to the suppression of recombination between Y and X (or Z and W in birds) following the accumulation of sex-specific alleles near sex-determining loci. The degree of gene expression imbalance between the sexes and also relati

The aim of this thesis is to research the relationship between economic growth and atmospheric pollution in China based on Environmental Kuznets Curve hypothesis. Three atmospheric pollutants are mainly tested in this research including industrial sulphur dioxide, industrial dust and industrial soot. Based on provincial economic and environmental data over 1991-2010, panel approach is applied to s

Abstract The barnacle, Stephanolepas muricata, a commensal epibiont of cheloniid sea turtles, occurs frequently on the sea turtles of the Golfo Dulce, Pacific Costa Rica. The aim of this study was to quantify the occurrence of S. muricata on green and hawksbill sea turtles, to describe its major attachment locations and to investigate potential routes for barnacle exposure. In-water sampling of s

Studiens syfte var att undersöka elevers upplevelse av kreativt klassrumsklimat och utövande av kreativa fritidsaktiviteter i förhållande till deras resultat på två kreativitetstest, om det finns några könsskillnader i förhållande till dessa variabler samt vilket samband som finns mellan de två testen. Studien innefattar totalt 106 elever i årskurs 6 och 7, varav 53 flickor och 52 pojkar samt en mThe aim of this study was to investigate students’ experience of a creative classroom climate and of their creative leisure activities in relation to their results on two creativity tests, as well as gender differences in relation to these variables and the relationship between the two tests. The study has 106 participants, 53 girls, 52 boys and one with gender unknown, studying in grade 6 and 7 o

Studiens bakgrund är de lärandemål, formulerade i termer av förväntade studieresultat, som ska finnas för samtliga utbildningar och kurser vid svenska universitet och högskolor. Syftet med studien är att genom kvalitativa intervjuer undersöka hur sex studenter på grundnivå låter sitt handlande styras av lärandemålen. Fokus ligger på studenternas studievardag och vilka synsätt och praktiker de utve

Purpose: The purpose of this study is to describe and analyze Dresser Wayne AB’s problem with percentage of completion method in a project. Methodology: With a deductive approach a case study was conducted. The survey methodologies used are qualitative interviews and analysis. Theoretical perspectives: The theoretical framework is based on literature concerning accounting control management, proje

Scanning electron microscopy is widely used in nanowire device fabrication. In spite of the attractive high resolution that scanning electron microscopy provides, it influences the electrical properties of III-V nanowires. Influence of electron beam irradiation on InAs, InSb and GaSb nanowires is investigated by fabricating field effect transistors using the heavily doped Si substrate as gate. It

In Sweden, migrants suffer from poorer sexual and reproductive health than the general population due to exposures associated with pre- and post-migration process and difficulties that arise when meeting a new heath system. Health literacy is a term that is increasingly used for explaining people’s access to health preventive services, and where migrant populations has shown to possess lower level

Människohandel är ett samhällsproblem där människor i en redan sårbar situation utnyttjas. Min undersökning behandlar människohandel för arbetskraft, jag har utfört en intervjustudie med tre fackförbund, där jag undersökt deras syn på skillnaden av skydd för olika kategorier av arbetstagare. Med hjälp av Hanna Arendts teori om medborgarskapets betydelse för att räknas som rättighetsinnehavare, harHuman trafficking is a social problem where people in an already vulnerable situation are taken advantage off. My research is regarding labor trafficking. I have conducted interviews with three different trade unions to get their views on the difference in protection for the various categories of workers. Hanna Arendt’s theory about the importance of citizenship in order to have human rights, hav

Syfte: Studiens syfte är att redogöra för tidigare forskning om fortsatt drift och olika omständigheter som påverkar revisorns uttalande om fortsatt drift, att undersöka om och i så fall hur relationen mellan ägare och företagsledning påverkar revisorns oberoende samt att jämföra en enkel konkursmodell med revisorer i frågan om fortsatt drift. Metod: En kvantitativ metod valdes för att möjliggöra

In this paper the laminar burning velocities of nitromethane, ethanol and nitromethane-ethanol mixtures has been determined by using heat flux method. The laminar burning velocity of ethanol was measured at atmospheric pressure, initial temperatures range 298-358 K and equivalence ratio 0.7-1.6. The flame speed of ethanol shows a satisfactory agreement with previous available data. The burning vel

The day of bud burst (DBB) and leaf senescence are two examples of time-to-event phenological processes influenced by climate factors. Time to graduation or quitting for engineering students is another example of time-to-event data, with the added complication of having multiple possible outcomes, or absorbing states. This master thesis elaborates upon the models presented in Song (2010) &quo

Ett nytt sätt att behandla cancer För att en cancercell ska kunna utvecklas från en normal cell måste det ske förändringar, mutationer, i den normala cellens gener som leder till att cancercellen kan föröka sig obegränsat. Om vi kan förstå denna process kan vi utveckla läkemedel som är mer riktade mot cancercellerna och har mindre biverkningar. Normalt är en cell beroende av signaler från omvärlAbstract The cell cycle is a tightly regulated process with many different checkpoints that monitor the progression and correct possible mistakes. During cancer development, the restriction point (R-point) is one of the most important control mechanisms that has to be altered in order to reach growth factor independent growth. The R-point is guarded by retinoblastoma protein (pRB), which forms a

Abstract A radar study was performed to compare flight parameters between sparrowhawks and common buzzards during autumn migration at the Falsterbo peninsula, Sweden. Common buzzards had higher flight altitudes and were more selective for wind, yet their air - and cross-country speeds were lower than those of sparrowhawks. Furthermore, common buzzards had higher glide ratio, but lower airspeed w

Global scale innovation is a new topic that is continuously gaining importance among companies, moreover multinational ones. The main aspects related to innovation in general were studied as well as the most important aspect of culture and cultural differences. Many theories related to the global consumer studies were reviewed. A qualitative study was performed in order to gain more knowledge abou
