This thesis examines posting of workers within the free movement of services in the European Union. The emphasis is on the case law of the European Court of Justice and in the role it has played in the liberalisation of the service sector in respect of posting of workers. The case law is examined from two different viewpoints: firstly, that of employment law and secondly, immigration law. The aim is to find out how active a role the Court has taken with regard these two fields of law and what are the implications of the Court’s judgments for the regulation on a national level. The first part of the thesis provides a general review of the Community law principles governing the freedom to provide services in the EU. The second part presents the Posted Workers’ Directive and the case law of the European Court of Justice before and after the enactment of the Directive from the viewpoint of employment law. Special attention is paid to a recent judgment in which the Court has taken a restrictive position with regard to a trade union’s right to take collective action against a service provider established in another Member State. The third part of the thesis concentrates, firstly, on the legal status of non-EU nationals lawfully resident in the EU. Secondly, it looks into the question of how the Court’s case law has affected the possibilities to use non-EU nationals as posted workers within the freedom to provide services. The final chapter includes a critical analysis of the Court’s case law on posted workers. The judgments of the European Court of Justice are the principal source of law for this thesis. In the primary legislation the focus is on Articles 49 EC and 50 EC that lay down the rules concerning the free movement of services. Within the secondary legislation, the present work principally concentrates on the Posted Workers’ Directive. It also examines proposals of the European Commission and directives that have been adopted in the field of immigration. The conclusions of the case study are twofold: while in the field of employment law, the European Court of Justice has based its judgments on a very literal interpretation of the Posted Workers’ Directive, in the field of immigration its conclusions have been much more innovative. In both fields of regulation the Court’s judgments have far-reaching implications for the rules concerning posting of workers leaving very little discretion for the Member States’ authorities.

The main idea of this study was to find out how immigrants understand and define successful co-operation and professional partnership in early childhood education. Another target of this research was to think over how the parents see professional partnership from their viewpoint, and how willing / ready the they are in engaging in the professional partnership with the day care personnel. The theoretical part of this research is based on theories of immigration and theories of it s different forms, theories of cultural varieties and theory of modernizing co-operation through using professional partnership. Also guidelines and policies for day care and early childhood education play a part in the theory section. Theory part is written to support research problems. The research method used in this study is peer interview. The interviewed are both immigrants and customers of day care services. The data collected is comprised of materials from peer interviews and personal background information. The interviewed were of Somalia and Russian ethnic groups. Interview were carried out in each group in the participants own mother tongue. These peer interviews showed that parents were interested and willing to discuss professional partnership. From this research one can conclude that the term professional partnership is seen as a complex term, and as a term difficult to understand. From the results it is seen that quite often the principles of professional partnership are not carried out in practise. According to the material gathered, the parents feel that lack of common language and prejudice against immigrants effectively prevents the professional partnership from being formed. The cultural differences can become challenging in a professional partnership. Based on this research, one can conclude that when different cultures meet, there has to be mutual will to understand and to be understood in order to make sure that the children s development, both educational and physical, is supported in a best possible way.

Introduction: Combination antiretroviral therapy (cART) has decreased morbidity and mortality of individuals infected with human immunodeficiency virus type 1 (HIV-1). Its use, however, is associated with adverse effects which increase the patients risk of conditions such as diabetes and coronary heart disease. Perhaps the most stigmatizing side effect is lipodystrophy, i.e., the loss of subcutaneous adipose tissue (SAT) in the face, limbs and trunk while fat accumulates intra-abdominally and dorsocervically. The pathogenesis of cART-associated lipodystrophy is obscure. Nucleoside reverse transcriptase inhibitors (NRTI) have been implicated to cause lipoatrophy via mitochondrial toxicity. There is no known effective treatment for cART-associated lipodystrophy during unchanged antiretroviral regimen in humans, but in vitro data have shown uridine to abrogate NRTI-induced toxicity in adipocytes. Aims: To investigate whether i) cART or lipodystrophy associated with its use affect arterial stiffness; ii) lipoatrophic SAT is inflamed compared to non-lipoatrophic SAT; iii) abdominal SAT from patients with compared to those without cART-associated lipoatrophy differs with respect to mitochondrial DNA (mtDNA) content, adipose tissue inflammation and gene expression, and if NRTIs stavudine and zidovudine are associated with different degree of changes; iv) lipoatrophic abdominal SAT differs from preserved dorsocervical SAT with respect to mtDNA content, adipose tissue inflammation and gene expression in patients with cART-associated lipodystrophy and v) whether uridine can revert lipoatrophy and the associated metabolic disturbances in patients on stavudine or zidovudine based cART. Subjects and methods: 64 cART-treated patients with (n=45) and without lipodystrophy/-atrophy (n=19) were compared cross-sectionally. A marker of arterial stiffness, heart rate corrected augmentation index (AgIHR), was measured by pulse wave analysis. Body composition was measured by magnetic resonance imaging and dual-energy X-ray absorptiometry, and liver fat content by proton magnetic resonance spectroscopy. Gene expression and mtDNA content in SAT were assessed by real-time polymerase chain reaction and microarray. Adipose tissue composition and inflammation were assessed by histology and immunohistochemistry. Dorsocervical and abdominal SAT were studied. The efficacy and safety of uridine for the treatment of cART-associated lipoatrophy were evaluated in a randomized, double-blind, placebo-controlled 3-month trial in 20 lipoatrophic cART-treated patients. Results: Duration of antiretroviral treatment and cumulative exposure to NRTIs and protease inhibitors, but not the presence of cART-associated lipodystrophy, predicted AgIHR independent of age and blood pressure. Gene expression of inflammatory markers was increased in SAT of lipodystrophic as compared to non-lipodystrophic patients. Expression of genes involved in adipogenesis, triglyceride synthesis and glucose disposal was lower and of those involved in mitochondrial biogenesis, apoptosis and oxidative stress higher in SAT of patients with than without cART-associated lipoatrophy. Most changes were more pronounced in stavudine-treated than in zidovudine-treated individuals. Lipoatrophic SAT had lower mtDNA than SAT of non-lipoatrophic patients. Expression of inflammatory genes was lower in dorsocervical than in abdominal SAT. Neither depot had characteristics of brown adipose tissue. Despite being spared from lipoatrophy, dorsocervical SAT of lipodystrophic patients had lower mtDNA than the phenotypically similar corresponding depot of non-lipodystrophic patients. The greatest difference in gene expression between dorsocervical and abdominal SAT, irrespective of lipodystrophy status, was in expression of homeobox genes that regulate transcription and regionalization of organs during embryonal development. Uridine increased limb fat and its proportion of total fat, but had no effect on liver fat content and markers of insulin resistance. Conclusions: Long-term cART is associated with increased arterial stiffness and, thus, with higher cardiovascular risk. Lipoatrophic abdominal SAT is characterized by inflammation, apoptosis and mtDNA depletion. As mtDNA is depleted even in non-lipoatrophic dorsocervical SAT, lipoatrophy is unlikely to be caused directly by mtDNA depletion. Preserved dorsocervical SAT of patients with cART-associated lipodystrophy is less inflamed than their lipoatrophic abdominal SAT, and does not resemble brown adipose tissue. The greatest difference in gene expression between dorsocervical and abdominal SAT is in expression of transcriptional regulators, homeobox genes, which might explain the differential susceptibility of these adipose tissue depots to cART-induced toxicity. Uridine is able to increase peripheral SAT in lipoatrophic patients during unchanged cART.

Vuosien 1830 ja 1924 välillä Yhdysvaltoihin muutti noin 35 miljoonaa eurooppalaista. Tämä niinkutsuttu "maahanmuuton vuosisata" päättyi varsin äkillisesti kun Yhdysvallat päätti rajoittaa maahanmuuttoa 1920-luvulla. Vuosina 1921 ja 1924 säädetyt lait asettivat kansallisuuteen perustuvat kiintiöt kaikille eurooppalaisille maahanmuuttajille; vuoden 1924 laki myös lopetti kokonaan japanilaisten maahanmuuton. Tämä työ tutkii näihin kiintiölakeihin johtanutta maahanmuuttajavastaisuuden kasvua sekä etenkin lakien ympärillä käytyä keskustelua. Pääpaino on kongressissa esitetyissä maahanmuuton vastaisissa argumenteissa. Nämä jakautuivat karkeasti ottaen kolmeen kategoriaan: maahanmuuton vastustajat sanoivat, että siirtolaisten vaikutus taloudelliseen tilanteeseen oli epäsuotuisa, siirtolaisten rodullinen ja kulttuurinen "laatu" oli huonontunut, ja siirtolaiset olivat radikaaleja ja bolshevismiin taipuvaisia. Erityistä huolta herätti maahanmuuttajien vaikutus Amerikan kulttuuriseen, rodulliseen ja poliittiseen yhtenäisyyteen. Huoli kansakunnan yhtenäisyydestä oli tulosta paitsi siirtolaisten määrästä myös amerikkalaisessa yhteiskunnassa tapahtuneista muutoksista. Erityisen tärkeitä olivat työväenliikkeen vaikutusvallan kasvu ja teollisuusjohtajien pyrkimys pysäyttää se. Maahanmuuttajien "bolshevismi" olikin käyttökelpoinen argumentti paitsi maahanmuuttajia myös amerikkalaisia työläisiä vastaan: teollisuusjohtajat painottivat että lakot ja työväenliike olivat tulosta siirtolaisten mukanaan tuomista "epäamerikkalaisista" ajatusmalleista, eivät yhteiskunnan epäoikeudenmukaisuudesta. Kongressin keskustelun lisäksi työssä käsitellään myös eri yhteiskunnallisten ryhmien ja vaikuttajien kantaa siirtolaisuuteen. Keskusteluun maahanmuutosta vaikuttivat etenkin eugenistit ja muut sosiaalitieteilijät, jotka väittivät itä- ja eteläeurooppalaisten olevan rodullisesti anglosakseja huonompia. Tämän väitteen vaikutusvaltaa lisäsivät yhteiskunnassa vallalla olleet ennakkoluulot, ja monet yhdistykset ja liikkeet (mm. Ku Klux Klan ja erilaiset isänmaalliset järjestöt) olivatkin tärkeitä rajoittamisen kannattajia. Keskustelu maahanmuutosta painottui ideologisiin ja tunteellisiin kysymyksiin, mutta rajoitusten taustalla oli myös konkreettisempia tekijöitä. Yhteiskunnan teollistuminen ja kaupungistuminen olivat pienentäneet siirtolaisista koituvaa taloudellista hyötyä: siirtolaisia ei enää tarvittu raivaamaan uusia viljelysmaita, kun taas tuotannon koneistuminen vähensi työvoiman tarvetta huomattavasti. Pitkän aikavälin taloudellisten tekijöiden roolin merkitys käy ilmeiseksi kun otetaan huomioon, että muut maahanmuuttomaat (esim. Kanada ja Australia) eivät juuri rajoittaneet siirtolaisuutta tänä aikana vaikka niissäkin esiintyi runsaasti rodullista ja kulttuurista maahanmuuttajavastaisuutta. Pääsyy rajoitusten vähäisyyteen näissä maissa oli juuri maahanmuuttajien tuoma taloudellinen hyöty, sekä teollisena työvoimana että maanviljelijöinä. Vaikka kiintiölakiehdotusten ympärillä käytiin kiivasta väittelyä, kongressi kuitenkin hyväksyi lait varsin suurella enemmistöllä. Siirtolaisia itseään lukuunottamatta varsin harvat näkivät lait haitallisina, kun taas useat erilaiset ryhmät katsoivat hyötyvänsä maahanmuuton rajoittamisesta. Avainsanat: siirtolaisuus, maahanmuutto, Yhdysvallat, 1920-luku, kiintiölait, maahanmuuton rajoittaminen

In this thesis, the genetic variation of human populations from the Baltic Sea region was studied in order to elucidate population history as well as evolutionary adaptation in this region. The study provided novel understanding of how the complex population level processes of migration, genetic drift, and natural selection have shaped genetic variation in North European populations. Results from genome-wide, mitochondrial DNA and Y-chromosomal analyses suggested that the genetic background of the populations of the Baltic Sea region lies predominantly in Continental Europe, which is consistent with earlier studies and archaeological evidence. The late settlement of Fennoscandia after the Ice Age and the subsequent small population size have led to pronounced genetic drift, especially in Finland and Karelia but also in Sweden, evident especially in genome-wide and Y-chromosomal analyses. Consequently, these populations show striking genetic differentiation, as opposed to much more homogeneous pattern of variation in Central European populations. Additionally, the eastern side of the Baltic Sea was observed to have experienced eastern influence in the genome-wide data as well as in mitochondrial DNA and Y-chromosomal variation – consistent with linguistic connections. However, Slavic influence in the Baltic Sea populations appears minor on genetic level. While the genetic diversity of the Finnish population overall was low, genome-wide and Y-chromosomal results showed pronounced regional differences. The genetic distance between Western and Eastern Finland was larger than for many geographically distant population pairs, and provinces also showed genetic differences. This is probably mainly due to the late settlement of Eastern Finland and local isolation, although differences in ancestral migration waves may contribute to this, too. In contrast, mitochondrial DNA and Y-chromosomal analyses of the contemporary Swedish population revealed a much less pronounced population structure and a fusion of the traces of ancient admixture, genetic drift, and recent immigration. Genome-wide datasets also provide a resource for studying the adaptive evolution of human populations. This study revealed tens of loci with strong signs of recent positive selection in Northern Europe. These results provide interesting targets for future research on evolutionary adaptation, and may be important for understanding the background of disease-causing variants in human populations.

Farmland bird species have been declining in Europe. Many declines have coincided with general intensification of farming practices. In Finland, replacement of mixed farming, including rotational pastures, with specialized cultivation has been one of the most drastic changes from the 1960s to the 1990s. This kind of habitat deterioration limits the persistence of populations, as has been previously indicated from local populations. Integrated population monitoring, which gathers species-specific information of population size and demography, can be used to assess the response of a population to environment changes also at a large spatial scale. I targeted my analysis at the Finnish starling (Sturnus vulgaris). Starlings are common breeders in farmland habitats, but severe declines of local populations have been reported from Finland in the 1970s and 1980s and later from other parts of Europe. Habitat deterioration (replacement of pasture and grassland habitats with specialized cultivation areas) limits reproductive success of the species. I analysed regional population data in order to exemplify the importance of agricultural change to bird population dynamics. I used nestling ringing and nest-card data from 1951 to 2005 in order to quantify population trends and per capita reproductive success within several geographical regions (south/north and west/east aspects). I used matrix modelling, acknowledging age-specific survival and fecundity parameters and density-dependence, to model population dynamics. Finnish starlings declined by 80% from the end of the 1960s up to the end of the 1980s. The observed patterns and the model indicated that the population decline was due to the decline of the carrying capacity of farmland habitats. The decline was most severe in north Finland where populations largely become extinct. However, habitat deterioration was most severe in the southern breeding areas. The deteriorations in habitat quality decreased reproduction, which finally caused the decline. I suggest that poorly-productive northern populations have been partly maintained by immigration from the highly-productive southern populations. As the southern populations declined, ceasing emigration caused the population extinction in north. This phenomenon was explained with source sink population dynamics, which I structured and verified on the basis of a spatially explicit simulation model. I found that southern Finnish starling population exhibits ten-year cyclic regularity, a phenomenon that can be explained with delayed density-dependence in reproduction.

This study examines Institutional Twinning in Morocco as a case of EU cooperation through the pragmatic, ethical and moral logics of reason in Jürgen Habermas’s discourse ethics. As a former accession tool, Twinning was introduced in 2004 for legal approximation in the context of the European Neighborhood Policy. Twinning is a unique instrument in development cooperation from a legal perspective. With its long historical and cultural ties to Europe, Morocco presents an interesting case study of this new form of cooperation. We will analyse motives behind the Twinning projects on illegal immigration, environment legislation and customs reform. As Twinning is a new policy instrument within the ENP context, there is relatively little preceding research, which, in itself, constitutes a reason to inquire into the subject. While introducing useful categories, the approaches discussing “normative power Europe” do not offer methodological tools precise enough to analyse the motives of the Twinning cooperation from a broad ethical standpoint. Helene Sjursen as well as Esther Barbé and Elisabeth Johansson-Nogués have elaborated on Jürgen Habermas’ discourse ethics in determining the extent of altruism in the ENP in general. Situating the analysis in the process-oriented framework of Critical Theory, discourse ethics provides the methodological framework for our research. The case studies reveal that the context in which they operate affects the pragmatic, ethical and moral aspirations of the actors. The utilitarian notion of profit maximization is quite pronounced both in terms of the number of Twinning projects in the economic sphere and the pragmatic logics of reason instrumental to security and trade-related issues. The historical background as well internal processes, however, contribute to defining areas of mutual interest to the actors as well as the motives Morocco and the EU sometimes described as the external projection of internal values. Through its different aspects, Twinning cooperation portrays the functioning of the pragmatic, ethical and moral logics of reason in international relations.
