This thesis deals with the problem of practical application of FDTD technique for simulation of image formation in coherence controlled holographic microscope. Various ways for obtaining scattering matrices are explored in detail and the optimal technique based on a rigorous calculation of the far field is proposed. The scattering matrix, containing information about the observed sample, is subsequently used in analytic calculation of holographic signal; two levels of approximation of pupil function are also evaluated. The results are compared with a traditional approach based on Rytov approximation resulting in specification of the parameter domain where the approximation is applicable. Based on the simulations of the microscope, the dependence of axial resolution on apertures of the objective and the condenser and sensitivity of the signal to changes of refractive index of the sample is also studied.

La démographie de l’espace sibérien constitue le cadre général de cette étude. L’analyse se concentre sur les processus migratoires et sur le rôle qu’ils jouent dans le peuplement et le dépeuplement de l’Est de la Russie. Si les statistiques officielles nous permettent de saisir à diverses échelles géographiques les tendances principales, plusieurs enquêtes de terrain, qualitatives et quantitatives sont au cœur de ce travail, menées dans deux régions de l’Est russe : le kraï de Krasnoïarsk et l’oblast de l’Amour, auprès de la population générale et d’un échantillon de migrants présents dans les deux régions d’étude et originaires d’Ukraine, d’Arménie, d’Azerbaïdjan, Kirghizistan, Ouzbékistan, Tadjikistan et Chine.Après avoir précisé les flux migratoires intrarégionaux, le processus d’exode rural, le déclin des villes secondaires et la forte attractivité des capitales régionales, l’étude portant sur l’échantillon de migrants met l’accent sur la distinction entre les temporaires et permanents, en tenant toutefois compte de l’impossibilité d’appliquer strictement un classement binaire à un phénomène complexe et fluide. Nous identifions différentes stratégies migratoires, indépendantes des statuts légaux accordés aux migrants en Russie. En tenant compte des intentions exprimées par les répondants, on est par ailleurs en mesure d’estimer le degré de conversion des temporaires en permanents, le pourcentage des étrangers ayant l’intention de s’installer à long terme en Russie et, en définitive, l’apport de l’immigration à la population des deux régions.A l’issue de cette recherche les projections démographiques permettent de réfléchir aux conséquences démographiques de différents contextes économiques et sociopolitiques de la Russie. La démarche fait ressortir une fois encore l’importance du facteur migratoire pour le devenir démographique de la Russie, ainsi que la nécessité d’un nouveau développement de l’attractivité des régions périphériques et de la Sibérie en général.Nous développons en conclusion une réflexion sur les conditions permettant un apport positif de la migration à l’économie et à la démographie sibérienne : favoriser la mobilité temporaire et à courte distance pour freiner la migration permanente de l’Est vers l’Ouest, améliorer le potentiel d’attraction des régions sibériennes en menant un réel processus de décentralisation politique et économique. Un tel processus n’est pas d’actualité, mais pourrait prendre place à moyen ou long terme. / The demographics of the Siberian area are the general framework of this study. The analysis focuses on migratory processes and the role they play in the population and depopulation of eastern Russia. Although the official statistics enable us to grasp the main trends on various geographical scales, several qualitative and quantitative field surveys are at the heart of this work, led in two regions of eastern Russia: Krasnoyarsk Krai and Amur Oblast, with the general population and a sample of migrants present in both study regions who were originally from Ukraine, Armenia, Azerbaijan, Kyrgyzstan, Uzbekistan, Tajikistan and China.After having described the intra-regional migratory flows, the rural exodus process, the decline of secondary cities and the strong appeal of the regional capitals, the study based on the sample of migrants places a strong emphasis on the difference between temporary and permanent migrants, yet takes into account the impossibility of strictly applying a binary classification to a complex and fluid phenomenon. We identify various migratory strategies that are independent from the legal statuses granted to migrants in Russia. Taking into account the intentions expressed by the respondents, we are able to estimate to what extent temporary migrants are converted to permanent migrants, the percentage of foreigners who intend to stay in Russia long term and give a definitive picture of immigration's contribution to the population of the two regions.At the end of this research, the demographic projections enable us to discuss the demographic consequences of various economic and socio-political contexts in Russia. The approach once again brings out the importance of the migratory factor to Russia's demographic future, as well as the need to newly develop the appeal of peripheral regions and Siberia in general.In conclusion, we discuss the conditions enabling the positive contribution of migration to the Siberian economy and demography: promoting temporary and short-distance mobility to slow down permanent migration from east to west and improving the potential for Siberian regions to attract migrants by leading a concrete political and economic decentralisation process. These processes are not yet in place, but could be implemented in the medium or long term.

As various of wireless techniques have been proposed to achieve fast and efficient data communication, it’s becoming increasingly important to protect wireless communications from being undermined by adversaries. A secure and reliable wireless physical layer design is essential and critical to build a solid foundation for upper layer applications. This dissertation present two works that explore the physical layer features to secure wireless communications towards the data confidentiality and user authentication. The first work builds a reliable wireless communication system to enforce the location restricted service access control. In particular, the work proposes a novel technique named pinpoint waveforming to deliver the services to users at eligible locations only. The second work develops a secure far proximity identification approach that can determine whether a remote device is far away, thus preventing potential spoofing attacks in long-haul wireless communications. This dissertation lastly describes some future work efforts, designing a light-weight encryption scheme to facilitate sensitive data encryption for applications which cannot support expensive cryptography encryption operations such as IoT devices.

This thesis aims to explore the spread of populist propaganda on social media on the case of the Dutch politician Geert Wilders and Twitter. The research questions of this thesis focus primarily on the message that is being spread by Mr. Wilders and his followers, the way his followers react to this content and the attempt to securitize Islam through populist propaganda. The thesis uses the methodology of discursive thematic interpretation to analyze the narrative that is being spread. In order to collect data for this analysis, the analytical tool NodeXL Pro has been employed. This tool made it possible to not only collect data and identify the people interacting with a theme, but also visualize their position within the network. The thesis uses datasets collected by NodeXL for the discursive thematic interpretation of data. The analysis itself is divided into different sections, first analyzing the content shared by Geert Wilders and identifying the themes and reconstructing the narrative. Next, the analysis moves on to more specific subsections, such as important hashtags or examples of active users from Wilders' proximity. NodeXL was also helpful in modelling the networks and discovering the echo chambers formed around Geert Wilders.

Syftet med denna uppsats är att belysa förskollärares roll när det uppstår situationer i förskolan där det uppmärksammas att ett barn far illa i sin uppväxtmiljö. Det är en kvalitativ enkätstudie som syftar till att synliggöra förskollärares egna kunskaper och erfarenheter av barn som far illa i sin uppväxtmiljö. Studien utgår från en hermeneutisk ansats där våra tolkningar, förståelser samt förförståelser ligger till grund för vårt analysarbete. Resultatet av studien visar på kunskap, bristande kunskap och erfarenhet hos examinerade förskollärare där barn far illa i sin uppväxtmiljö men även en brist på stödjande dokument i förskolor för hur arbetet med dessa barn bör gå till. Förskollärarna lyfter att en utbildning inom området vore av vikt för att kompetensutveckla personalen på förskolorna.

Indiana University-Purdue University Indianapolis (IUPUI) / In the area of forensic chemistry, improved or new analysis methods are continually being investigated. One common and powerful technique used in forensic chemistry is wall-coated open-tubular column (WCOT) gas chromatography with electron ionization single quadrupole mass spectrometry (GC-MS). Improvements to and effectiveness of alternatives to this instrumental platform were explored in an array of parallel inquiries. The areas studied included the column for the chromatographic separation, the universal detection method employed, and the fragmentation method used to enhance molecular identification. Superfine-micropacked capillary (SFµPC) columns may provide an alternative to commercial packed GC columns and WCOT GC columns that combines the benefits of the larger sample capacity of packed columns and the benefits of the excellent separation capabilities and mass spectrometry (MS) flow rate compatibility of WCOT columns. SFµPC columns suffer from high inlet pressure requirements and prior reported work has required specialized instrumentation for their use. Fabrication of and chromatography with SFµPC GC columns was successfully achieved with typical GC-MS instrumentation and within the flow rate limit of a MS. Additionally, the use of higher viscosity carrier gasses was demonstrated to reduce the required inlet pressure for SFµPC GC columns. Recently, a new vacuum ultraviolet spectrometer (VUV) universal detector has been commercialized for GC. The ability of VUV detectors to acquire absorbance spectra from 125 nm to 430 nm poses a potential alternative to MS. As such, GC-VUV provides an exciting potential alternative approach to achieving excellent quantitative and qualitative analysis across a wide range of analytes. The performance of VUV and MS detectors for forensic analysis in terms of quantitative and qualitative analysis was compared. Analysis of alkylbenzenes in ignitable liquids was explored, which can be important evidence from suspected arson fires and are difficult to differentiate with MS. The VUV detector was found to have superior specificity and comparable sensitivity to the MS detector in scan mode. Addition of thermolysis (Th) as an orthogonal fragmentation pathway provides the opportunity to increase the differences between MS fragmentation patterns. Fragmentation has been widely established to aid in identification of molecules with MS by providing characteristic fragments at characteristic relative abundances. However, molecules with very similar structures do not result in sizable spectral differences in all cases with typical MS fragmentation techniques. A series of Th units were fabricated and integrated into GC-Th-MS instruments. Th-MS was conducted with the thermally labile nitrate esters across a range of instrumentation and thermal conditions.

Förskolan ska ge varje barn förutsättningar att uppleva trygghet och få sina behov tillgodosedda. Utifrån barnkonventionen och förskolans läroplan har förskollärare och andra yrkesverksamma i förskolan, en skyldighet att motverka att barn utsätts för fysiskt och/eller psykiskt våld i hemmet. Vid missförhållanden i hemmet där vårdnadshavaren brister i omsorg om barnet, kan förskolan bli en betydande del för barnets vardag och utveckling.Syftet med vår studie är att undersöka förskollärares utmaningar i arbetet med barn som far illa, eller riskerar att fara illa i hemmet. För att uppnå studiens syfte intervjuades åtta förskollärare med hjälp av semistrukturerade intervjuer, utifrån en kvalitativ intervjumetod. Intervjuerna genomfördes via mail och fysiska möten. Materialet analyserades med hjälp av Bronfenbrenners utvecklingsekologiska systemteori, med fokus på barnets utveckling i olika system.Studien visar att kunskap i ämnet har en betydande roll för hur förskollärare ska få möjlighet att utföra sitt uppdrag. Förskollärarna i studien menar att barnets rätt till en trygg plats ligger till grund för välmående och utveckling. Trots utmaningar i att se varningssignaler och samverka med vårdnadshavare, anser förskollärarna att deras lyhördhet och flexibla arbetssätt skapar goda förutsättningar för att uppmärksamma utsatta barn. Dock menar många av förskollärarna att det behövs fortbildning och kompetensutveckling i ämnet, för att skapa bästa möjliga förutsättningar för barn i förskolan.

Undeniable geopolitical significance of the Russian Far East renders development of the region a matter of national priority for the entire 21st century. Enormous untapped potential of the region is not limited to the range of possibilities offered by export of its natural resources. Developing a non-resource export potential of the Russian Far East offers a way of ensuring sustainable economic growth - a key component of regional, and national, competitive capabilities. At the core of Michael E. Porter's book "The Competitive Advantage of Nations" is a model of national competitive advantage that introduces the concept of business clusters as drivers of economy. Applying Porter's analytical framework and building on recent experience of government-driven innovative cluster development in Russia, the thesis seeks to propose an economically sound model of International Medical Education Cluster for the Russian Far Eastern Federal District. The cluster will support Russia's engagement with Asia and complement one of the world's largest and fastest growing industries - that of healthcare - by addressing one of its most acute needs, namely the growing worldwide shortage of healthcare personnel. The proposed model capitalizes on federal policy of internationalisation of Russian higher education,...

There is a puzzling occurrence in Western Europe: Some far-right populist parties, traditionally seen as antithetical to liberalism, are appropriating liberal rights for their own illiberal ends. On the premise that the parties instrumentalise liberal elements to achieve more legitimacy in a climate of tolerance and respect for human rights in Western Europe, this thesis examines how far-right populist parties use human rights for mobilising purposes. Using Clifford Bob’s four conceptual elements of mobilising human rights rhetoric, in a qualitative content analysis the language of three Western European far-right populist parties is analysed. It is argued that, by drawing from a liberalism of fear, far-right populists frame human rights as a Western achievement, under threat by immigration from Islamic countries and the “corrupt elite” that allows for immigration to continue. By doing so, populists manage to incorporate human rights rhetoric in their mobilisation efforts, without challenging human rights per se.
