The number of unaccompanied asylum-seeking children (UASC) has increased significantly in Sweden since the summer of 2006. Due to Sweden’s high rate of asylum application approvals, it has become a main destination country. Concurrently, unaccompanied asylum-seeking children have decreased in other more traditional European destination countries, such as Germany, the United Kingdom, Belgium, the Netherlands and Norway. The majority of the UASC come from Afghanistan and Somalia. There is insufficient knowledge regarding these children’s reasons and patterns for the migration to Sweden. This is a case study based on semi-structured interviews with key informants that have been strategically chosen for this study. The Migration System theory, which is based on key mechanisms of the globalization theory, is used in this study. Restricted asylum regulations in Western countries have created a “migratory industry” with human smugglers, which facilitate and expand the irregular migration. The migratory industry greatly influences the children’s choice of destination. Without the assistance of human smugglers, a migration would be impossible for these children. The conclusion of this study demonstrates the importance of informal social networks that are the reason behind the increase of UASC in Sweden.

This thesis investigates the students who graduated from the Umeå university in respect to their migration patterns and their employment situation. The study focuses on young adults with higher education, who due to their age are highly mobile and are a significant part of human capital which provides an influx of collective intelligence and has a positive effect on the region. The migration is investigated in terms of defining different migration patterns and the employment is looked at in terms of horizontal match/mismatch.Additionally the factors that have relation to migration patterns and employment match are studied; among them are gender, family status, age and field of studies. It is also studied if there is an income penalty if the employment mismatch occurs.Descriptive statistics as well as logistic regressions are used to research the aim of the study. This is done by means of data from Statistics Sweden available at the Department of Geography and Economic History at Umeå University. The results show that graduates are highly mobile because of their age and the family status plays a more significant role than the employment match for migration. However, the probability to migrate is decreasing if an individual has a child, but it increases chances of being a return migrant. Still the decision to migrate is complex and cannot be determined by one factor only.The employment match appeared to be rather low for Umeå university graduates and there was an income penalty which slightly decreased with the flow of time.

In 2001, 3269 unidentified individuals were found in a mass grave on the Northern part of Vilnius, Lithuania. Artifactual context indicates that these individuals were likely soldiers that were a part of Napoleon’s Grand Army. Stable oxygen isotope analysis was performed on bone apatite from 9 femoral bone samples to determine whether or not these individuals were Lithuanian locals and to test ratio variation. If individuals were foreigners, then geographical origins were approximated utilizing percentages of C4 plants from Holder (2013) and δ18O values that were extracted from bone apatite. The carbonate oxygen isotope compositions (δ18Ocarbonate) of bone apatite from the femoral samples (-4.4‰ to -6.2‰) indicate that these individuals were from central and western Europe (-4.0‰ to -6.9‰). It is significant that none of the individuals have values consistent with the area around Lithuania (-10.0‰ to -11.9‰), because it means that they all were non-local. It is also indicative that the Lithuanians were not burying their citizens in the grave and therefore strongly support that these individuals were Napoleonic soldiers. Additionally, although C4 percentages in the diet ranged from 17.8% to 31.7%, which overlaps with eastern European consumption patterns (approximately 15% to 25% of C4 plants) (Reitsema et al., 2010), the slight shift towards a higher C4 percentage is more representative of a central and western European diet. These results are significant because they provide stable isotopic evidence that these individuals were Napoleon’s soldiers whom participated in the Russian campaign of 1812.

Streekontwikkelingsbeleid en differensiële verstedeliking is twee fundamentele temas binne die ruimtelike beplanningsveld. Streekontwikkelingsbeleid is veral sedert die Tweede Wêreldoorlog in Europa geïmplementeer, waar regerings besef het dat die vryemarksisteem nie noodwendig optimale ekonomiese groei op streekvlak verseker nie. Doelwitte Die primêre doelwit van hierdie studie is die integrering van effektiewe en volhoubare streekontwikkelingsbeleid met die konsep van differensiële verstedeliking, ten einde 'n effektiewe stedelike bestuursmeganisme daar te stel. Sekondêre doelwitte sluit in: * om die beginsels en doelwitte van streekontwikkelingsbeleid en streekontwikkelingsinstrumente te bepaal; * die analisering van Suid-Afrikaanse streekontwikkelingsbeleid in terme · van bogenoemde klassifikasie; * ondersoek na die teoretiese en praktiese toepassings van die differensiële verstedelikingsmodel; * om die geldigheid van die differensiële verstedelikingsmodel te bepaal in die Gauteng Funksionele Metropolitaanse Streek; en * om relevante streekontwikkelingsbeleid te integreer met sosio-ekonomiese tendense in 'n stedelike sisteem, met spesifieke verwysing na die Gauteng Funksionele Metropolitaanse Streek. Metodiek Die rasionaal vir die formulering van streekontwikkelingsbeleid word in Hoofstuk Twee beskryf. Regerings en ander streekowerhede formuleer streekontwikkelingsbeleid ten einde spesifieke doelstellings te behaal. Hierdie doelstellings verander met tyd en is gewoonlik streekspesifiek. Die relevante owerheid of instansie neem 'n besluit in terme van bogenoemde fundamentele benaderingswyses, waarna 'n keuse ten opsigte van spesifieke beleidsopsies en -instrumente geneem word. Hoofstuk Drie beskryf laasgenoemde beleidsinstrumente asook meer gedetailleerde beleidselemente soos wat dit op projekvlak geïmplementeer word. In Hoofstuk Vier word die geskiedkundige implementering van streekontwikkelingsbeleid in Suid-Afrika en spesifiek vir die Gauteng- en omliggende streek, ondersoek. Die Gauteng Funksionele Metropolitaanse Streek het reeds 'n gevorderde vlak van stedelike ontwikkeling binne die Suid-Afrikaanse konteks bereik en was histories instrumenteel in die implementering van streekontwikkelingsbeleid. 'n Sentrale tema in hierdie studie, is die beginsel dat stedelike komplekse 'verouder' met tyd. Soos wat hierdie stedelike komplekse ontwikkel, kan verskillende migrasie- en ekonomiese produksiepatrone onderskei word in dieselfde areas, maar die patrone is georiënteer in verskillende rigtings en gebaseer op verskillende motiverings. Hierdie tendense word deur die differensiële verstedelikingsmodel in Hoofstuk Vyf aangespreek. Na die afskaffing van diskriminerende wetgewing, is die verwagting dat die bevolkingsgetalle van groter stedelike komplekse vir 'n aansienlike tydperk steeds sal toeneem. In Hoofstuk Ses word hierdie migrasieprosesse, asook veranderende produksiepatrone in die studiegebied ontleed, gebaseer op die resultate van die mees onlangse sosio-ekonomiese opnames. Bevindings Uit die studie blyk dit duidelik dat streekontwikkelingsbeleid steeds geïmplementeer word in reaksie op bepaalde ongelykhede in 'n streek. Laasgenoemde verwys gewoonlik na hoe vlakke van werkloosheid en kwynende ekonomiese sektore in sekere stede. Die voorstel in die studie is die vroegtydige formulering van streekontwikkelingsbeleid vir al die elemente binne die stedelike sisteem, gegewe die huidige ontwikkelingsvlak in terme van die differensiële verstedelikingsmodel. Hiervolgens kan sentra met toenemende ekonomiese- en bevolkingsgroei vroegtydig geïdentifiseer en ontwikkeling bevorder word. Soortgelyk, kan plekke met kwynende ekonomieë en bevolkingsgetalle ondersteun word in die fase van stedelike groei. Die sosio-ekonomiese profiel van die studiegebied, naamlik die Gauteng Funksionele Metropolitaanse Streek, het in die studie bewys dat dit 'n identifiseerbare ontwikkelings- of 'verouderingsroete' gevolg het sedert die 1960s. Dit is ook duidelik in die studie dat die effektiwiteit van streekontwikkelingsbeleid en die volhoubaarheid daarvan gewoonlik omgekeer eweredig is aanmekaar: soos volhoubaarheid toeneem, neem ekonomiese effektiwiteit af. Die voorgestelde integrering van streekontwikkelingsbeleid en differensiële verstedeliking behoort hierdie negatiewe tendens ten opsigte van effektiwiteit en volhoubaarheid om te keer, ten einde toenemende volhoubaarheid en effektiwiteit te verseker in die stedelike ontwikkelingsproses. / PhD (Town and Regional Planning), Potchefstroom University for Christian Higher Education, 2001

This work aims to compare two models of migration, on the one hand, Czech migration to the capital city of Mexico on the other hand, Mexican migration to the capital city of Czech Republic. This text looks at migration as a cultural-social act, with its main protagonists, individual migrants. Therefore this work is not demographic, but anthropological based on qualitative research. With the background of basic sources it offers the monitoring of behavior of two groups of migrants, especially in their adaptation process. The basic research question then is: What is the process of cultural adaptation of the Czechs in Mexico, DF and Mexicans in Prague? To what extent are these models similar or different? Finding answers to this question necessarily leads to other topics, reply to completion, which are: How strong are the tendencies of development of ethnic communities? How respondents experienced the process of adaptation and changes of their identity? What strategies of living in the destination country they occupied? To what extent they communicate with compatriots and embassies? This paper provides both theoretical basis, which defines the terms of migration, cultural adaptation and identity, and practical sections, which through examples of qualitative research describe the process of cultural adaptation...

The objective of this Bachelor thesis is to analyze moving patterns in Norrköping’s municipality. The main aim is to analyze the migration to, from, and within the municipality of Norrköping, not only for the population as a whole but also for groups of special interest. Another aim is to compare migration patterns in Norrköping with those of other municipalities in Sweden.Several data sets have been used, each of them extracted from population statistics carried out by Statistics Sweden (SCB).Data mining using association analysis is used for finding the migration pattern within Norrköping’s municipality and several questions are examined using descriptive statistics. Mann-Kendall tests are used to determine interesting trends in the population changes.The results show that pre-school children do not remain longer in the city centre than they did previously; people moving to Norrköping from within Sweden move mostly to the city centre, though immigrants from abroad mainly favour Hageby and Åby tätort. Furthermore, the results show that people generally move to areas that are geographically similar to where they were or have been before. There is a decrease in migration of people with a Humanities or Arts background, as there is for those with a pedagogy and teacher training background. Areas with a decrease in migration are the suburbs as well as built-up areas at the fringe of the municipality. Norrköping has both lower immigration and emigration than other comparable Swedish municipalities. / Syftet med denna kandidatuppsats är att analysera flyttmönster i Norrköpings kommun. Målet är att analysera både flyttningar till, från, och inom Norrköpings kommun för dels hela populationen och dels speciellt intressanta grupper. Ett annat mål är att jämföra flyttmönster i Norrköping med några andra kommuner i Sverige.För att kunna genomföra dessa analyser har flera datamaterial använts. Gemensamt för datamaterialen är att de allihop baseras på Statistiska Centralbyråns (SCB:s) befolkningsstatistik.För att hitta mönster för hur människor flyttar inom Norrköpings kommun används associationsanalys. Med hjälp av deskriptiv analys undersöks olika särskilt intressanta områden av omflyttningarna i kommunen. Vidare används Mann-Kendalltester för att se om det finns några särskilt intressanta trender i befolkningsutvecklingen.Resultatet visar att ingen förändring har skett när det gäller ifall barn i förskoleåldern bor kvar i stadskärnan i större utsträckning än tidigare. Inflyttare från Sverige flyttar i stor utsträckning till stadskärnan, medan Hageby och Åby tätort är vanliga att flytta till om man flyttar från utlandet. Vidare visar resultatet att människor oftast flyttar till geografiskt nära områden samt områden som har ungefär samma bostadsform som det man tidigare bott i. Flyttningsnettot är negativt för de med utbildning inom Humaniora och konst samt Pedagogik och lärarutbildning. De områden som har negativ befolkningsutveckling ligger i utkanten av centralorten eller är tätorter i utkanten av kommunen. Norrköpings kommun har lägre inflyttning och utflyttning än de flesta andra jämförbara kommuner.

These isolates were genotyped using ten microsatellite loci. Low genotypic diversity, departures from Hardy-Weinberg equilibrium (HWE), gametic disequilibrium and high degree of population subdivision found in these populations are consistent with predominantly asexual reproduction, short-distance dispersal of vegetative propagules, and limited long-distance dispersal. The observed levels of subdivision could be explained by asymmetric historical migration among the soybean-infecting populations, denoting TO06 as the founder population. Evidences of restricted gene flow and a mixed reproductive mode would fit the fungus into the medium-high risk category for pathogen evolutionary potential, suggesting the need for caution when applying fungicides or breeding for major-gene resistance. We also developed a method to detect SNPs in multiple loci by PCR, converting RFLP probes in six highly informative and polymorphic co-dominants sequencing markers. We have identified single and multiple alleles per isolate in each analyzed region, indicating the fungus heterokaryotic condition. The highest number of SNPs was detected at the R68L marker, with 18 mutations along 303 base pairs. The developed set of new markers proved to be a viable genotyping system, allowing precise allelic discrimination, with the potential to complement the methods already described to study the R. solani AG-1 IA population biology and making evolutionary studies feasible.
