For well over a century, migration researchers have recognized the lack of adequate distance measures to be a key obstacle for advancing understanding of internal migration. The problem arises from the convention of spatially defining migration as the crossing of administrative borders. Because administrative regions vary in size, shape, and settlement patterns, it is difficult to tell how far mov
During the 20th century, a number of actors and institutions set out to develop taxonomies of the Swedish population. This thesis examines the most important social classification system, the social group, which despite its great importance in administrative, scientific, commercial, political and media contexts has received little attention in historical research. Invented by the Central Bureau
Democratic theory and research have lately been criticized in several fields. A classic and contested question is the role of the working class in democracy and democratization. Yet, it has been overshadowed by elite strategies that have been at the core of the most influential analytical framework in regard to late twentieth-century transitions. This is where some of the criticism has been laid.
The increasingly frequent use of forensic evidence in the prosecution of criminal cases should in the long run result in increased analysis of its effectiveness. To date, such analysis has been limited, most probably due to rights of parties to use forensic evidence to support their respective arguments in cases and the rights of the courts to assess and rely on such evidence in criminal cases. Pr
Popular Abstract in English At the beginning of 20th century, scientists started to realize that atoms exhibited the discrete behaviour, e.g. the energies of bond electrons were not continuously distributed, but had discrete values. Light is also transmitted as discrete packages (called photons). These phenomena can not be explained by classical physics, which has been accepted as the law of descrThe work presented in this thesis was concerned with investigating the relevant spectroscopic properties of Ce ions randomly doped in an Y2SiO5 crystal at low temperatures (around 4 K), in order to develop a technique and an experimental set-up to detect the fluorescence photons emitted by a single Ce ion. The aim of the work was to determine whether a single Ce ion (referred to as the readout ion
Popular Abstract in English This thesis considers a model of high energy particle collisions. The model is based on the so called BFKL formalism which is valid only at low x, that is collisions at very high energies, such as at the LHC. The intial state of the incoming particles are simulated by colour dipoles in transverse space evolved through rapidity. With this approach, all fluctuations are dThis thesis considers a model of high energy particle collisions.

Control of the dissemination of pathogens in the food production chain is an on-going process with new challenges emerging as pathogenic bacteria evolve and express enhanced virulence characteristics. Staphylococcus aureus and Listeria monocytogenes are two notorious pathogens responsible for staphylococcal food poisoning (SFP) and listeriosis: a foodborne intoxication and an infectious disease re
Background In pediatric patients, computed tomography (CT) is important in the medical chain of diagnosing and monitoring various diseases. Because children are more radiosensitive than adults, they require minimal radiation exposure. One way to achieve this goal is to implement new technical solutions, like iterative reconstruction.

High concentrations of salts in agricultural soils are an environmental problem that has plagued human civilization from its very beginning. Already the earliest civilizations in ancient Mesopotamia struggled with increasing concentrations of salt on irrigated fields. Also in modern times, salinization of soils, particularly of agricultural soils is still a problem restricting agricultural productSoil salinization is a pressing agricultural problem in many areas of the world, particularly in areas heavily reliant on irrigation agriculture. While the negative effects of salinity on crop plants have been widely studied, its effects on soil microorganisms have received less attention, and the impact of soil salinity on both microbial community structure and functioning is not well understood.
René Descartes’ Meditations on First Philosophy explores foundational philosophical and theological questions through a method of radical skepticism. Central to this exploration is the concept of the evil demon, a hypothetical being that challenges human capacity to comprehend and perceive reality. Descartes’ meditations are pivotal to the development of rationalist philosophy, bridging epistemolo
A commonly used method in remediation projects is to excavate the contaminated soil and treat it in another location or put it in a landfill. The remediation site is then refilled with crushed stones. When the original soil and its initial organisms are removed and replaced with only crushed stones, the environmental properties are changed. This can affect both primary production and the flora and
This study aims to explore the experiences women face due to the criminalisation of abortions in the United States. It presents a thematic analysis of the criminalisation of abortion through a feminist framework, examining its profound implications on women's lives. Utilizing secondary data from social media platforms and news outlets, this research will also employ netnography and ethnography
Climate change is posing a threat to the whole world. In some places, prolonged droughts cause problems whereas extreme rainfall causes problems elsewhere. Rotterdam faces increasing threats from the North Sea because of rising sea levels. The areas that are not protected by dikes are the most vulnerable and will be the first to flood. This project focuses on an unprotected area of Rotterdam whic
The purpose of this essay is to describe the way the prepositions from and från work, both semantically and syntactically. However, the focus is on the translation from from into Swedish. The question this essay aims at answering is: “is there any mutual correspondence between English and Swedish use of their respective prepositions”? The question is relevant since a large amount of the literature
Despite many years of progress towards closing the gender pay gap and achieving racial equality, women from ethnic minority groups in the United Kingdom earn less compared to their male counterparts and to the population average. The extent of channelling into certain areas of occupation and employment are a prominent feature of the employment of minority groups in the UK and is a key mechanism in
