Метою даної статті є вивчення причин і наслідків "витоку мізків" і явище "витрати мізків", що мало місце в Україні. Виявлено основні стимулятори і дестимулятори, що впливають на процеси трудової міграції. В результаті демографічного обстеження, результати попередніх досліджень в області демографії, політичної науки і освіти об'єднані в даному дослідженні. Методологія проведення дослідження - це порівняльний аналіз з використанням вторинних даних (відкритих статистичних джерел), статистичний аналіз, методологія побудови сценаріїв; якісний аналіз даних (відкриті інтерв'ю, аналіз результатів попередніх досліджень). Формалізований набір базових сценаріїв, що дозволяють відтворити систему міграційних факторів і розробити превентивні заходи щодо уповільнення процесу. Тенденції міграції були класифіковані за статтю, віком, місцем проживання, місцезнаходженням, напрямком міграції і за рівнем кваліфікації мігрантів.Целью данной статьи является изучение причин и последствий "утечки мозгов" и явление "расхода мозгов", имевшее место в Украине. Выявлены основные стимуляторы и дестимуляторы, влияющие на процессы трудовой миграции. В результате демографического обследования, результаты предыдущих исследований в области демографии, политической науки и образования объединены в данном исследовании. Методология проведения исследование - это сравнительный анализ с использованием вторичных данных (открытых статистических источников), статистический анализ, методология построения сценариев; качественный анализ данных (открытые интервью, анализ результатов предыдущих исследований). Формализован набор базовых сценариев, позволяющих воссоздать систему миграционных факторов и разработать превентивные меры по замедлению процесса.

The aim of this paper is to explore the causes and consequences of “brain drain” and “brain waste” phenomena that took place in Ukraine. The main stimulants and destimulants were identified that impact the processes of labour migration. The demographic survey results, the findings of previous research in demography, political sciences, and education tendencies are united in current research. The methodology of the research is a comparative analysis by using secondary data (open statistical sources), statistical analysis, scenario design methodology; qualitative data analysis (open interviews, previous findings). The set of basic scenarios was formalized that allow to recreate the system of migration factors and to design the preventive measures to slow down the process. The trends of migration were classified by gender, by age, by residence location, by destination, and by the levels of qualification.
This research was funded by the grant from the Ministry of Education and Science of Ukraine "Reforming the lifelong learning system in Ukraine for the prevention of the labor emigration: a coopetition model of institutional partnership" (№0120U102001).

Full textAbstract:
Однією з умов розбудови Української правової держави на сучасному етапі розвитку є визначення напрямів міграційної політики та вдосконалення системи державного управління міграційними процесами відповідно до міжнародних стандартів у сфері реалізації прав людини і громадянина. Особливого значення набувають події, які негативно вплинули на соціально – економічний розвиток держави та стали підґрунтям для перегляду міграційної політики держави, а також надали підстав для реформування системи органів державного управління та подолання проґалин в діяльності відповідних органів. Одним з таких органів є Державна міграційна служба України. Відповідно до Положення «Про державну міграційну службу України» Державна міграційна служба України є центральним органом виконавчої влади, діяльність якого спрямовується і координується Кабінетом Міністрів України через Міністра внутрішніх справ України. Держана міграційна служба України входить до системи органів виконавчої влади та утворюється для реалізації державної політики у сферах міграції (імміграції та еміграції), у тому числі протидії нелегальній (незаконній) міграції, громадянства, реєстрації фізичних осіб, біженців та інших визначених законодавством категорій мігрантів. Правова основа діяльності Державної міграційної служби України знаходиться на стадії формування й відповідно вимагає внесення певних змін, доповнень у існуючі нормативно – правові акти та прийняття нових. Слід зауважити, що на шляху розвитку та оптимізації діяльності Державної міграційної служби України існує ряд проблемних питань, які потребують вирішення, однією з таких є визначення адміністративно – правових засад діяльності Державної міграційної служби України. Що і являє собою актуальність обраної теми.

Full textAbstract:
The process of formation and implementation of the national security state policy currently is one of the most acute issue in Ukraine. Modern realities of Ukraine’s existence as an independent state require, within the framework of the national security policy implementation, to take into account the country's request to realize national interests in all spheres of society's life. Nowadays, the country faces intensification of the unregulated (illegal) migration processes and the lack of an effective state regulation system of migration processes, which constitute a direct threat to the country national security, promote the criminalization growth and the organized criminal groups’ formation, and contribute to the social tension exacerbation in society. The bodies of the State Migration Service of Ukraine face with an urgent need for a more profound migration perception as a socio- economic phenomenon and an active search for qualitatively new approaches to migration policy formation and control over population territorial movements.

Forster, Emma. "Migration decision-making processes : an empirical investigation." Thesis, Edinburgh Napier University, 2000. http://researchrepository.napier.ac.uk/Output/3711.
Full textAbstract:
This thesis has two purposes. The first is to investigate the motivation for household migration - in particular, the associations between the different reasons for moving and the characteristics of owner-occupier movers in Scotland, their houses and the distances they travel. The second is to investigate the extent to which the migration decision is a longitudinal one, and from this longitudinal analysis to highlight the extent of latent migration. Little longitudinal research has previously been carried out on the migration decision. The thesis uses two recent, large-scale and under-utilised data sources to investigate each of these issues. Firstly, the associations with motivations for migration are investigated using the 'Migration and Housing Choice Survey' (MHCS) which contains information from 10,010 households. The advantage of this cross-sectional source lies in its provision of detailed information on motivations at a national level of coverage. The large-scale, national coverage makes it possible to investigate many types of migration flow. This advantage is not shared by any other British research into motivations for migration and only three other data sets elsewhere. Secondly, the extent to which the decision to n-iigrate is part of an on-going process is investigated using the 'British Household Panel Survey' (BBPS). This new and under-exploited source of migration data contains longitudinal information from 10,264 individuals in the first wave and holds approximately this sample size through each of the following four waves. This thesis makes four key contributions to knowledge. The first three are based on the detailed and systematic analysis of the reasons for residential migration behaviour of owner-occupiersin Scotland,u sing the MHCS. Firstly, the reasonsf or moving, as suggestedb y previously small-scaler esearch,h ave been confirmed by this large-scale data set. Secondly, this thesis has extended - and in some cases refuted - the findings of previous researchb y investigatingt he bivariate associationsb etween each of the reasons for moving and each possible explanatory variables (these being characteristicso f migrants, of their home and of the distancest hey move). This has been investigated using much wider selection of reasons for moving and of characteristicsth an hasb eenp reviouslyd one. Thirdly, this thesish as shown that lifecycle stage exerts a considerable amount of influence on the reasons given for moving, whilst still operating in conjunction with other variables, such as distance moved and housing features. The MIHCS can, for the first time, enable research into the connection between the factors influencing migration flows and the factors influencing motivations for migration. Fourthly, this thesis has investigated how migration decisions and preference for migration relate over time, using longitudinal data (the BHPS). This has shown that a considerable amount of latent mobility is present in Britain, and even more importantly, has identified the characteristics of the latent migrants and frequent movers. In addition, this thesis has offered some methodological pointers for future migration research. Overall, the use of these two important but under-utilised data sets, the MECS and the BBPS, have enabled analyses to be undertaken that are unique in the history of nýgration research. V

Full textAbstract:
Nowadays, one of the global indicators of sustainable development of the country is the level of transparency of the economics and its attractiveness to foreign investors. In the context of economic growth and enhanced integration processes, the issue of attracting foreign investments in the country's economy is quite urgent.
It is worth noting that the investment climate is a set of social, economic, organizational, legal, political, socio-cultural prerequisites, which determines the attractiveness and feasibility of investing in a particular industry of the country.

Full textAbstract:
This thesis advances the theoretical and conceptual understandings of contemporary rural gentrification, drawing upon the case study of Tenterden and Cranbrook, in the North Weald of Kent. Based on rich, empirical findings from semi-structured interviews, content analyses of media sources, and household surveys of 320 respondents, it is shown that two distinct, and often inter-connected, flows of rural gentrifiers have migrated into Tenterden and Cranbrook. This emphasises the value of a micro-geographic perspective of rural gentrification, to capture internal socio-economic and cultural differentiation between gentrifiers. It is argued that the findings will have a major bearing on future studies of contemporary rural gentrification and counter-urban migration.

Full textAbstract:
L’objectif de cette thèse est d’étudier la capacité des charbons humiques à générer des hydrocarbures.Un charbon humique d’âge crétacé, provenant du bassin de Sabinas (Mexique) et deux autres d’âge carbonifèreprovenant du bassin du Donets (Ukraine) ont été sélectionnés dans le cadre de cette étude. Ces échantillons ont été caractérisés puis pyrolysés en milieu confiné. Les résultats de cette pyrolyse révèlent que la classification macérale grossière d’un charbon en grandes familles (liptinite, vitrinite et inertinite), ne permet pas de définir correctement sa capacité à produire du bitume au cours de la maturation thermique. Les résultats de la modélisation 1D et 2D du système pétrolier dans le bassin du Donets confirment la bonne capacité des charbons du Donets à générer des hydrocarbures. La zone de génération maximale des hydrocarbures est obtenue dans la partie Sud-Est de la zone étudiée. Cependant, les phases de soulèvement et d’érosion des couvertures étanches au Permien supérieur et Crétacé supérieur ont causé une migration intense et une dismigration des hydrocarbures à la surface. Ainsi, de façon générale, l’absence d’occurrences commerciales d’huiles associées aux charbons humiques carbonifères semble plutôt due à l’histoire et à l’âge du bassin. Finalement, la modélisation prédit des accumulations de méthane au Nord-Ouest du bassin du Donets, une région pratiquement inexplorée, là où les couvertures étanches permiennes et mésozoïques sont présentes.Une relation linéaire simple entre la génération du méthane et le %Rr a été obtenue après les expériences de pyrolyse. Les conclusions déduites de l’utilisation de cette relation empirique dans le bassin de Donets sont comparables à celles issues de l’observation de terrain et de la modélisation numérique 2D de ce bassin. Il reste néanmoins à l’appliquer sur un plus grand nombre de bassins à charbons afin de la généraliserThe objective of this thesis is to study the capacity of two different humic coals to generate hydrocarbons.Two bituminous humic coals were selected for this study in objective to evaluate their petroleum potentiality, a Cretaceous coal from the basin of Sabinas, and two Carboniferous coals from the basin of Donets. Pyrolysis in confined system was used in this work. More oil, wet gas, solid bitumen and even methane were produced during the pyrolysis of Donets coals than its amount produced from Olmos coal.The obtained results of modeling study of the petroleum system in Donets Basin show that: coalification level increases towards the E & SE parts of studied area of Donbas, the major erosion phase occurred at late Permian time with maximum total erosion in the SE part, the main phase of hydrocarbon generation occurred during the Carboniferous and early Permian subsidence phase, three phases of oil expulsion from source rock in Donets Basin were predicted, the major quantity of trapped methane is located in the southern and northern parts of main anticline.Finally, in this work a simple experimental relation between the generation of methane and %Rr of coal was formalized and validated by using field data and the results of the modeling study in the basin

Full textAbstract:
This thesis examines labour migration as an outcome of the interaction between the state and the informal economy, by considering the trends of contemporary labour migration from Ukraine to Southern Europe. It contends that in both the sending and receiving countries, migration policies either disregard or severely limit labour migration, while their informal economies facilitate the development of migration. This basic contradiction sustains migration flows over time. The main argument of the thesis is that migration develops within the system of interacting informal economies. I demonstrate the embeddedness of migration in the informal economy by using the case of Ukrainian migration to Italy.The role of the informal economy in the development of migration is examined across several dimensions. First, I argue that the recent labour migration from Ukraine emerged as a strategy of the informal economy, continuing the previous strategies of cross-border trading and short-term migration to Central Europe. These economic practices were the innovative responses of the population to the decline of the state economy and to the absence of economic reforms. Migration developed in the space between the state and the market economy.
Second, the flows of labour migration were 'invisible' to states, and developed outside state control and regulation. This thesis demonstrates that the migration policies of the Ukrainian state disregarded the process of out-migration of Ukrainian citizens. Similarly, Italian immigration policies did not recognise the existing flows of labour migration. The informal economy of the receiving state resolved the contradiction between the economic demand for migrant workers and restrictive migration policies and enabled access to the receiving economy.
However, access to the receiving labour market through the informal economy contributed to the disadvantaged incorporation of migrants and prevented their integration into the receiving society. The analysis of economic incorporation demonstrates that the informal economy channelled Ukrainian migrants to the secondary labour market with low earnings, a lack of benefits, and no possibility of professional advancement. The mode of access to the receiving economy and the resulting illegality heavily influenced the position of Ukrainian migrants in the labour market.
Finally, the analysis of Ukrainian labour migration to Italy demonstrates that alternative migration-facilitating institutions were developed in the absence of the state recognition of labour migration. These institutions paralleled the institutions of the official labour markets and allowed migrants to implement income-generating projects. In addition, migration was facilitated by the supporting institutions of the receiving society, which counteracted the restrictive immigration laws and political controls on migration. The migration-supporting institutions were predicated on the strategies of circumventing state control which developed from participation in the informal economy of the sending country. Labour migration from the former Soviet Union would not be possible without these informal practices and the culture of avoiding state control in economic activities.
The proposed analysis answers the challenge posed by the recent Ukrainian labour migration to conventional theories on migration, whose approaches usually omit references to the meso-level of migration processes, and consider either the structural-economic or the micro- determinants of migration. This thesis presents the informal economy both as a structural factor which enables migration and as a characteristic of the migrant agency that facilitates it.
By doing that, the thesis also complements the literature on migration to Southern Europe and argues that migrations are not simply encouraged by the informal economies of the receiving countries, but they emerge from, and are facilitated by, the informal economies of the sending countries. To perpetuate migration migrants creatively use the resources of the informal economy in conjunction with strategies of circumventing the state. This argument holds for a number of ex-Soviet countries, which suffered severe economic crises during the disintegration of the state-controlled socialist economies, and consequently produced significant labour migrations to Western Europe.

Crane, Jonathan Austin. "SECURITY, DEVELOPMENT, AND (IM)MOBILITY: THE UNEVEN GEOGRAPHY OF MIGRATION AND BORDER MANAGEMENT IN UKRAINE." UKnowledge, 2013. http://uknowledge.uky.edu/geography_etds/10.
Full textAbstract:
As a country of origin, transit, and destination for migrants that now borders four European Union (EU) member countries, Ukraine has seen future integration possibilities with the EU become, in part, conditional upon its willingness to cooperate in controlling cross-border migration. The EU is now “externalizing” aspects of migration and border control to Ukraine through making investments in Ukraine’s capacity to selectively “manage” cross-border flows in line with EU security and economy priorities. In the context of this emerging spatial arrangement of EU externalization, this thesis analyzes how, by whom, and to what effect migration is being managed in and through Ukraine. Policies of migration and border management are now materializing in Ukraine in relation to actors and discourses that incorporate imperatives for security and development in their approaches to governance. Therefore, this thesis investigates migration and border management at the geopolitical nexus of development, security, and migrant (im)mobility. It does this with a critical concern for those migrants whose exclusion from the EU is subject to humanitarian management in Ukraine.

A tese tem como objetivo aprofundar o conhecimento sobre um novo grupo de jovens imigrantes portugueses no Brasil, compreendendo suas motivações de saída do seu país de origem, ao mesmo tempo das respetivas motivações de escolha do Brasil como país de chegada. A pesquisa enquadra-se num contexto pós crise econômica de 2008, que parece despertar a decisão do jovem português de emigrar. Este jovem, porém, apresenta características próprias e diferenciadas de outros fluxos de imigrantes portugueses no Brasil ao longo da história, tratando-se de um jovem muito mais qualificado e que pretende e se acha capaz de estabelecer e ganhar a sua independência através da migração. Durante este trajeto, muito menos previsível do que muitas vezes esperado, o jovem precisa se desenrascar para conseguir conquistar os seus objetivos, conquistando a sua independência financeira e se integrando em uma nova sociedade – com seus prós e contras relatados pelas experiências individuais.
The thesis aims to deepen the knowledge of a new group of young portuguese immigrants in Brazil, namely its departure motivations from their country of origin as the respective motivations of choosing Brazil as a country of arrival. The research is part of a 2008 post-crisis context that seems to awaken the portuguese youth to emigrate. This young man, however, has its own and different characteristics of other flows of portuguese immigrants in Brazil throughout history, these ones more qualified and feeling able to establish and gain their independence through migration. During this path, much less predictable than often expected, the young have to manage to conquer your goals, achieving financial independence and feel progressively integrating into a new society - with its pros and cons reported by individual experiences during the interviews.

Full textAbstract:
Controlled thermonuclear fusion may become an attractive future electrical power source. The most promising of all fusion machine concepts is called a tokamak. The fuel, a plasma made of deuterium and tritium, must be confined to enable the fusion process. It is also necessary to protect the wall of tokamaks from erosion by the hot plasma. To increase wall lifetime, the high-Z metal tungsten is foreseen as wall material in future fusion devices due to its very high melting point. This thesis focuses on the following consequences of plasma impact on a high-Z wall: (i) erosion, transport and deposition of high-Z wall materials; (ii) fuel retention in tokamak walls; (iii) long term effects of plasma impact on structural machine parts; (iv) dust production in tokamaks. An extensive study of wall components has been conducted with ion beam analysis after the final shutdown of the TEXTOR tokamak. This unique possibility offered by the shutdown combined with a tracer experiment led to the largest study of high-Z metal migration and fuel retention ever conducted. The most important results are: - transport is greatly affected by drifts and flows in the plasma edge; - stepwise transport along wall surfaces takes place mainly in the toroidal direction; - fuel retention is highest on slightly retracted wall elements; - fuel retention is highly inhomogeneous. A broad study on structural parts of a tokamak has been conducted on the TEXTOR liner. The plasma impact does neither degrade mechanical properties nor lead to fuel diffusion into the bulk after 26 years of duty time. Peeling deposition layers on the liner retain fuel in the order of 1g and represent a dust source. Only small amounts of dust are found in TEXTOR with overall low deuterium content. Security risks in future fusion devices due to dust explosions or fuel retention in dust are hence of lesser concern.QC 20170630

Ukraine ratified the Convention in 1997, and in 2000 the Ministry of Education and Science issued the first recognition decisions. During 2000–2012, the recognition procedure in Ukraine was called ‘nostrification’, as in many postSoviet countries. However, since 2010 the procedure has been reformed and a course taken toward harmonizing it with the European practices, taking into account the recommendations of the Lisbon Convention Committee in a timely manner. Since 2010, a legal act governing the recognition of foreign education qualifications had been changed three times, and now a new (fourth) edition after the public debate is being prepared for adoption. The name of the procedure was also changed in 2011 in accordance with the terminology used in the Bologna Process – the recognition of foreign degrees, recognition of educational documents, and recognition of qualifications. In Ukraine, since 2015, in addition to the relevant Ministry, the higher education institutions also have been authorized to recognize educational documents. However, the outdated term ‘nostrification’, references and analysis of outdated regulations can still be found both on the information resources of higher education institutions and in the scientific articles and research papers.
Конвенція про визнання кваліфікацій , що стосується вищої освіти в Європейському регіоні (Лісабон, 1997) є основним міжнародним документом в області визнання іноземних освітніх кваліфікацій для країн, включно з Україною, які підтримують ідею створення Європейського простору вищої освіти в рамках Болонського процесу. Україна ратифікувала Конвенцію в 1997 році, а у 2000 році Міністерство освіти і науки України прийняло перші рішення про визнання. У 2000-2012 роках процедура визнання в Україні називалася "нострифікацією", як і в багатьох пострадянських країнах. Однак з 2010 року процедура була реформована і взятий курс на її гармонізацію з європейською практикою, своєчасно враховані рекомендації Комітету Лісабонської конвенції. З 2010 року правовий акт, який регулює визнання іноземних освітніх кваліфікацій, змінювався тричі, і зараз готується до прийняття нова (четверта) редакція, яка пройшла громадське обговорення. Назва процедури також була змінена в 2011 році відповідно до термінології, яка використовується в Болонському процесі - визнання іноземних ступенів, визнання документів про освіту і визнання кваліфікацій. В Україні з 2015 року, крім відповідного міністерства, вищі навчальні заклади також уповноважені визнавати документи про освіту. Однак застарілий термін "нострифікація", посилання та аналіз застарілих нормативних актів все ще можна знайти як на інформаційних ресурсах вищих навчальних закладів, так і в наукових статтях та наукових роботах .

Full textAbstract:
Travel times from a refraction and wide-angle reflection seismic survey across the Coast Plutonic Complex and Stikine terrane of British Columbia were inverted to derive two dimensional P and S-wave seismic velocity models of the crust and uppermost mantle. A felsic upper crust and a felsic to intermediate middle crust are observed in both the batholith complex and the accreted Stikine island arc terrane. The P and S wave models demonstrate a high-velocity (P 7.0 km/s, S 3.8 km/s) layer in the lower crust beneath the youngest (late Cretaceous to Eocene) portion of the continental arc complex. In contrast, the lower crust under the Stikine terrane has lower velocities consistent with amphibolite or other hydrated mafic rocks. The Moho is at ~35 km depth under the Stikine terrane, deepens to ~38 km beneath the youngest portion of the arc, then shallows towards the coast. The high velocity zone under the younger portion of the Coast Plutonic Complex has a 1.81 Vp/Vs ratio and is interpreted to have a bulk composition of mafic garnet granulite. This garnet granulite and large volumes of granodiorite-dominated melt were created by arc dehydration melting of amphibolite (or hydrated gabbro) in the pre-existing lower crust
Reverse time migration method was applied to image aftershocks recorded by a dense array deployed after the 2011 Virginia earthquake. Events as tiny as magnitude -2 were successfully imaged as point sources. The propagation of energy release as a function of time and space was observed for events larger than magnitude 2.5. Spatial resolution of the images was ~200 m, which synthetic data tests show was primarily limited by the temporal sampling rate. Improved temporal and spatial sampling could produce images with sharper resolution.Ph. D.

Full textAbstract:
The investigation of the relationships between migration processes and the reconstructions of social identities and of social relations within local, national and international contexts illustrates how social change in an Oaxacan community in Mexico is a complex, multi-faceted process. This study examines how migration processes and social change shape and are shaped by people and practices in specific historical moments interacting dialectically with broader social, economic and political structures. By paying greater attention to the quotidian and to the choices that people make as they go about their daily lives, the heterogeneity and multiplicity of community members' subjectivities and experiences are highlighted. Gender, ethnicity, race, age, class, sexuality, and religion are examined as crucial variables in processes of social differentiation and in the social reproduction of gender/racial/class hierarchies in which women and men are situated. The research applies the concept of hegemony to demonstrate that power is not separate from meaning; the social construction of meanings plays an important role in the creation of consent, collaboration or resistance. Community members have internalized their own domination through hegemonic processes, reproducing the dominant social order, yet they frequently challenge their own particular social locations within this social order. Migration processes and the globalization of communication and consumption in advanced capitalism have played key roles in these processes. New experiences and information technologies have led to a redefining and re-presenting of meanings and practices which have had negative and positive impacts on individuals, on families and on the community.

La tesi doctoral conclou que la cooperació en política d'immigració entre la UE i Europa Oriental no consisteix en l'adopció sistemàtica de normes de la UE. Argumenta que la UE ha promogut fonamentalment normes de la UE en l'àmbit de seguritat (acords de readmissió i Gestió Integrada de Fronteres). Malgrat tot, a causa de la manca de poder suficient de la UE i a baixes percepcions de legitimitat de la UE entre els veïns d’Europa Oriental, la UE ha ofert incentius en l'àmbit de la mobilitat (política de visats i associacions per a la mobilitat).

Uns dels resultats més significatius de la tesi és que la UE promou activament, en el marc de la liberalizació de visats, la convergència normativa cap a normes internacionals en matèria d'estat de dret.

La comparativa entre els països d'Europa Oriental mostra que els instruments adoptats són similars per l'objectiu de la UE de ser coherent. Tanmateix, el poder de negociació de cada país amb la UE ha donat peu a condicions més o menys favorables pel país. A més a més, les percepcions de legitimitat i la voluntat de cada país d'apropament a la UE són elements clau. En conjunt, Ucraïna, Moldàvia i Geòrgia són països favorables a l'apropament a la UE mentre que Rússia ha construït una cooperació pragmàtica en matèria d'immigració amb la UE, influint en la institucionalització de l'agenda d'immigració amb Europa Oriental.

In 2004, the European Union (EU) launched the European Neighbourhood Policy (ENP) to strengthen cooperation in areas such as migration. In particular, the external dimension of the EU migration policy in Eastern Europe (the Eastern Partnership countries and Russia) has been very active and under huge academic scrutiny, mostly with studies claiming that the EU exports its own norms. Yet, this Europeanisation approach does not take into account the interests and capacities of Eastern European countries, as well as their perceptions of legitimacy. A decade after the launch of the ENP, this thesis addresses the question of what norms are actually adopted in the EU-Eastern Europe migration policy convergence. Three models of policy convergence (towards EU norms, towards international norms and towards bilaterally-agreed norms) are identified, depending mainly on the structure of power and perceptions of legitimacy in Eastern Europe. Migration policy convergence is applied to the cases of (I) readmission, (II) visa, (III) border management and (IV) labour migration. The doctoral dissertation concludes that the EU-Eastern Europe migration cooperation has not consisted in the systematic adoption of EU norms. It argues that the EU primarily has promoted security-related EU norms (readmission agreements and Integrated Border Management). However, due to lack of enough EU leverage and low perceptions of EU legitimacy among the Eastern neighbours, the EU has offered incentives in the field of mobility (visa policy and mobility partnerships). Empirical evidence shows weaknesses in policy convergence to EU norms, consisting mainly in socialisation measures (information exchange and capacity-building). One of the main findings of the thesis is that the EU is actively promoting, in the framework of visa liberalisation, policy convergence towards international norms in the area of rule of law. In fact, norms emanating from the Council of Europe and the United Nations are perceived as more legitimate than EU norms. However, this EU role as norm-transmitter has to be nuanced by the fact that to date the EU has played a relatively limited role in promoting international norms in the area of migrants' rights. Finally, convergence to bilaterally-agreed norms has been the least predominant. A comparison across Eastern European countries shows that the policy instruments adopted are by and large similar for the sake of consistency. Nonetheless, the leverage of each country vis-à-vis the EU has usually shaped more or less favourable conditions for the country. In addition, the perceptions of legitimacy and willingness of each country to come closer with the EU are essential. Overall, Ukraine, Moldova and Georgia are willing countries whereas Russia has built a pragmatic cooperation on migration with the EU, playing a role in the institutionalisation of the migration agenda to Eastern Europe. Finally, the thesis contributes overall to debate on the EU soft power in the Neighbourhood, concluding that the adopted migration policy instruments are much more oriented at promoting security than mobility.

Full textAbstract:
Leader cells are a fundamental biological process that have only been investigated since the early 2000s. These cells have often been observed emerging at the edge of an artificial wound in 2D epithelial cell collective invasion, created with either a mechanical scrape from a pipette tip or from the removal of a plastic, physical blocker. During migration, the moving cells maintain cell-cell contacts, an important quality of collective migration; the leader cells originate from either the first or the second row, they increase in size compared to other cells, and they establish ruffled lamellipodia. Recent studies in 3D have also shown that cells emerging from an invading collective group that also exhibit leader-like properties. Exactly how leader cells influence and interact with follower cells as well as other cells types during collective migration, however, is another matter, and is a subject of intense investigation between many different labs and researchers. The majority of leader cell research to date has involved epithelial cells, but as collective migration is implicated in many different pathogenic diseases, such as cancer and wound healing, a better understanding of leader cells in many cell types and environments will allow significant improvement to therapies and treatments for a wide variety of disease processes. In fact, more recent studies on collective migration and invasion have broadened the field to include other cell types, including mesenchymal cancer cells and fibroblasts. However, the proper technology for picking out dynamic, single cells within a moving and changing cell population over time has severely limited previous investigation into leader cell formation and influence over other cells. In line with these previous studies, we not only bring new technology capable of dynamically monitoring leader cell formation, but we propose that leader cell behavior is more than just an epithelial process, and that it is a critical physiological process in multiple cell types and diseases.

Cell migration is a dynamic process essential for many fundamental physiological functions, including wound repair and the immune response. Migration relies on precisely orchestrated events that are regulated in a spatially and temporally controlled manner. Most traditional approaches for studying migration, such as genetic methods or the use of chemical inhibitors, do not offer insight into these important components of protein function. However, chemical tools, which function on a more rapid timescale and in localized regions of the cell, are capable of providing real-time information about protein activity. Herein, the development and application of chemical approaches to investigate proteins central to cell migration are presented. Myosin II, an ATPase motor protein required for cell motility, is activated by phosphorylation of the associated myosin regulatory light chain (mRLC) protein at Serl9. To generate a photoactivated mRLC variant that offers control over the timing and localization of myosin activity, the mRLC has been prepared by expressed protein ligation for the site-specific incorporation of 1-(2-nitrophenyl)ethyl (NPE)-caged phosphoserine at position 19. The NPE caging group masks the phosphate functionality and inhibits protein function until irradiation at 365 nm releases the native phospho-mRLC to restore myosin activity. Introduction of the caged mRLC into cells enables interrogation of the role of myosin in coordinating cell contractility. To expand the scope of the caging approaches, the NPE caging group has been applied in concert with the [7-(diethylamino)coumarin-4-yl]methyl (DEACM) group, which is released by irradiation at 420 nm, to enable two different phosphopeptides to be sequentially released within one system. Preparation of DEACM-caged phosphoamino acid building blocks for solid phase peptide synthesis enables convenient incorporation of these residues into peptides and proteins. This sequential uncaging approach has been exploited to initiate and subsequently inhibit a biochemical reaction in an enzyme-independent fashion using two wavelengths of light. Finally, a fluorogenic sensor to monitor the real-time activity of the GTPase Cdc42, an essential regulator of migratory processes, has been developed. The solvatochromic fluorophore 4-N,N-dimethylamino-1,8-naphthalimide has been incorporated into a protein fragment that binds only the activated conformation of Cdc42. This sensor reports Cdc42 activation through significant increases in fluorescence and has been applied in a cellular context to monitor endogenous Cdc42 activity. This fluorogenic sensor and the caging approaches together demonstrate the power of chemical tools for interrogating diverse aspects of cell migration.

Full textAbstract:
Thermonuclear fusion may become an attractive future power source. The most promising of all fusion machine concepts is the tokamak. Despite decades of active research, still huge tasks remain before a fusion power plant can go online. One of these important tasks deals with the interaction between the fusion plasma and the reactor wall. This work focuses on how eroded wall materials of different origin and mass are transported in a tokamak device. Element transport can be examined by injection of certain species of unique and predetermined origin, so called tracers. Tracer experiments were conducted at the TEXTOR tokamak before its final shutdown. This offered an unique opportunity for studies of the wall and other internal components: For the first time it was possible to completely dismantle such a machine and analyse every single part of reactor wall, obtaining a detailed pattern of material migration. Main focus of this work is on the high-Z metals tungsten and molybdenum, which were introduced by WF6 and MoF6 injection into the TEXTOR tokamak in several material migration experiments. It is shown that Mo and W migrate in a similar way around the tokamak and that Mo can be used as tracer for W transport. It is further shown how other materials - medium-Z (Ni), low-Z (N-15 and F), fuel species (D) - migrate and get deposited. Finally, the outcome of dust sampling studies is discussed. It is shown that dust appearance and composition depends on origin, formation conditions and that it can originate even from remote systems like the NBI system. Furthermore, metal splashes and droplets have been found, some of them clearly indicating boiling processes.QC 20151203

Full textAbstract:
The higher educational system in the UK plays a crucial role in the economic development of the country and significantly impacts on the future labour market outcomes for individuals. With participation rates in higher education continually increasing and the recent changes to student financing burdening the student with more of the costs of higher education, the decision of where and what to study has become increasingly important. Despite this, there has been little work conducted to date that analyses in detail the migratory patterns of the large student population in the United Kingdom and their movements into Higher Education (HE). The overall aim of this thesis is to advance the current understanding of the student migration processes in the United Kingdom by considering three broad areas of enquiry and analysis; patterns and measurement of student migration, characteristics and correlations of student migration and lastly, future outcomes of student migration. This research uses data from the Higher Educational Statistics Agency (HESA) to provide a cross-sectional snapshot of the student migration situation in the UK. The thesis puts forward a unique typology that is used to categorise and measure the different migration decisions that a person can undertake in order to attend a Higher Educational Institution (HEI). Using this typology, the results demonstrate that, the previously assumed traditional transition in to higher education of migrating away from the parental home to study at a HEI is no longer the majority transition experienced by HE students in the UK. Secondly, a new spatial classification of student migration is created and the results show a clear difference in the migration outcomes of students from the South of the UK compared to the North, with the latter being less likely to migrate. Statistical modelling of the student migration process in the UK showed that migration into a HEI in the UK is not equal across ethnicity, socio-economic background and gender. Finally, the results regarding the impact of migrating in order to attend a HEI on the labour market outcomes after graduating were marginal. No clear causal impacts of the migration decision on the future labour market outcomes were identified.

Full textAbstract:
A series of local and bench scale laboratory experiments and bench and field scale numerical simulations were conducted to develop a better understanding of the interrelationship between nonwetting phase (NWP) source zones and downgradient aqueous phase concentrations in saturated porous media contaminated by immiscible organic liquids. Specific emphasis was placed on the factors governing the rate of NWP source zone evolution and the factors governing the rate of mass transfer from the NWP to the aqueous phase. Hysteretic NWP relative permeability-saturation (krN-SW) relationships were measured at the local scale for six sands to examine the relationship between krN-SW functions and porous media type. Parameterization of the measured constitutive relationships revealed a strong correlation between mean grain diameter and the maximum value of NWP relative permeability. The measured krN-SW relationships, were validated through a bench scale experiment involving the infiltration, redistribution, and immobilisation of NWP in an initially water saturated heterogeneous porous medium. This match of simulation to experiment represents the first validation of a multiphase flow model for transient, fixed volume NWP releases. Multiphase flow simulations of the bench scale experiment were only able to reproduce the experimental observations, in both time and space, when the measured krN-SW relationships were employed. Two-dimensional field scale simulations of a fixed volume NWP release into a heterogeneous aquifer demonstrate the influence of spatially variable krN-S relationships correlated to porous media type. Both the volume of the NWP invaded porous media, and the length of time during which NWP is migrating, will be under predicted if variable (correlated) kr,N is not accounted for in the numerical model iv formulation. This under prediction is exacerbated as the mean intrinsic permeability of the release location decreases. A new, thermodynamically-based interfacial area (IFA) model was developed for use in the single-boundary layer expression of mass transfer as an alternative to existing empirical correlation expressions. The IFA model considers consistency and continuity of constitutive relationships, energy losses, effective specific interfacial area for mass transfer, and dissolution of residual NWP. A bench scale experiment involving the release and dissolution of a transient NWP source zone in heterogeneous porous media was conducted to evaluate the appropriateness of the developed IFA model when utilised to predict NWP dissolution rates. Comparison of measured downgradient dissolved phase concentrations and source zone NWP saturations in time and space with those from numerical simulations of the experiment reveal that the proposed IFA model is superior to both a local equilibrium assumption and existing empirical correlation expressions. This represents the first mass transfer model validated for the dissolution of a complex NWP source zone. Twodimensional simulations at the field scale of multiphase flow and dissolution suggest that employing existing mass transfer expressions instead of the IFA model lead to incorrect predictions of the life spans of NWP source zones, downgradient dissolved phase concentrations, and the rate of mass flux through a downgradient boundary. The practical implication of this research is that accurate numerical predictions of the evolution of a transient NWP source in porous media require consideration of krN-S relationships and NWP / aqueous phase IFA, as these factors dictate the rates of the key subsurface contaminant processes of migration and dissolution, respectively.

Full textAbstract:
Das künstliche Radionuklid 137Cs wurde seit über einem halben Jahrhundert in die Natur eingebracht. Sein erstes Erscheinen in Sedimenten der zentraleuropäischen Seen korrespondiert mit den Nuklearwaffentests in den 60er-Jahren des 20. Jahrhunderts. Die stärkste Kontaminierung der europäischen Seen und Flüsse entstand als Folge des radioaktiven Niederschlags nach dem Unfall in Tschernobyl im Frühjahr 1986. In dieser Arbeit wurde das Migrationsverhalten des künstlichen 137Cs im Lago Maggiore und anderen Seen im Alpenvorland als Folge dieses Niederschlags untersucht. Der Lago Maggiore zählt zu den größten Trinkwasserreservoiren südlich der Alpen. Nach dem Unfall in Tschernobyl gingen ungefähr 20 kBq•m-2 des 137Cs auf die Oberfläche des Sees nieder. Im Zeitraum von 2003 bis 2005 wurden Sedimentkerne und Wasserproben an sieben unterschiedlichen Stellen des Lago Maggiore entnommen. Diese Arbeit beschäftigt sich mit Daten über die Verteilung des 137Cs in den Zuflüssen, dem Wasser des Sees, in Schwebstoffen und Bodensedimenten und mit der Assoziierung von 137Cs mit verschiedenen geochemischen Fraktionen. Um den Abfluss des 137Cs aus dem Wassereinzugsgebiet in den Fluss zu modellieren, wurde ein Compartmentmodell verwendet. Zur Modellierung der Aufnahmemenge von 137Cs im Sediment und der vertikalen Verteilung innerhalb dessen wurde ein Diffusions-Konvektions-Modell entwickelt. Dieses Modell berücksichtigt die Aufnahme von Aktivität durch Sedimentation, Fixierung und Rücklösung, retardierte Diffusion, die Verdichtung des Sediments sowie den Einfluss konkurrierender Ionen auf die retardierte Diffusion innerhalb des Sediments. Die Ergebnisse der Parameteroptimierung – im Wesentlichen die Sedimentationsrate und der 137Cs-Verteilungskoeffizient Kd, welcher die Aufnahme der Aktivität in das Sediment determiniert – werden erörtert und mit denen anderer europäischer Seen, die eine ähnliche 137Cs-Deposition, aber unterschiedliche limnologische Eigenschaften aufweisen, verglichen. Zur Beurteilung der Bioverfügbarkeit von 137Cs wurde die 137Cs-Aktivitätskonzentrationen von Fischproben aus dem Lago Maggiore gemessen. Aus bereits existierenden Daten und unseren Messergebnissen wurden 137Cs Fisch-Wasser Konzentrations-Verhältnisse errechnet und mit denen für andere Seen, die von ähnlichen 137Cs-Kontaminationen betroffen sind, verglichenArtificial Cs-137 has been introduced into the environment for more than half a century. Its first appearance in central European lake sediments corresponds to the nuclear weapons testing in the 1960s. The largest contamination of European lakes and rivers occurred as a consequence of the fallout after the Chernobyl accident in spring 1986. In this work the migration behaviour of artificial Cs-137 in Lago Maggiore and other pre-alpine lakes as a consequence of these fallouts was studied. Lago Maggiore is one of the largest drinking water reservoirs in the south of the Alps. After the Chernobyl accident roughly 20 kBq•m-2 of 137Cs were deposited onto the lake surface. From 2003 to 2005 bottom sediment cores and water samples were collected at 7 different locations of Lago Maggiore. Data on the 137Cs distribution in tributaries, lake water, suspended matter, bottom sediments, and the 137Cs association to different geochemical fractions are presented in this work. To model the run-off of 137Cs from the watershed into the lake a compartment model was used. For modeling the input of 137Cs into and the vertical distribution within the sediment a diffusion–convection type model was developed. This model takes into account the uptake of activity by sedimentation, fixation and redissolution, retarded diffusion, the influence of competing ions on the retarded diffusion within the sediments, and compaction of sediments. The results of the parameter optimization – mainly the sedimentation rate and the 137Cs distribution coefficient Kd, which determines the uptake of activity into the sediment – are discussed and compared with those of other European lakes characterized by similar 137Cs deposition levels but different limnological properties. To estimate the bioavailability of 137Cs, its activity concentrations in fish samples from Lago Maggiore were measured. Combining the existing data with our measurements, 137Cs fish–water concentration ratios were calculated and compared with those for other lakes which were affected by similar 137Cs contamination

Full textAbstract:
The thesis begins with a general introduction to population genetics in chapter 1. I review the fundamental processes of evolution - mutation, recombination, selection, gene flow and genetic drift - and give an overview of Bayesian inference in statistical population genetics. Later, I introduce the studied species, Alpine ibex (Capra ibex ), and its recent history. This history is intimately linked to the structured population in the Swiss Alps that provides the source of genetic data for this thesis. A particular focus is devoted to approximate Bayesian computation (ABC) in chapter 2, a method of inference that has become important over the last 15 years and is convenient for complex problems of inference. In chapter 3, the biological focus is on estimating the distribution of mutation rates across neutral genetic variation (microsatellites), and on inferring the proportion of male ibex that obtain access to matings each breeding season. The latter is an important determinant of genetic drift. Methodologically, I compare different methods for the choice of summary statistics in ABC. One of the approaches proposed by collaborators and me and based on boosting (a technique developed in machine learning) is found to perform best in this case. Applying that method to microsatellite data from Alpine ibex, I estimate the scaled ancestral mutation rate (THETA anc = 4Neu) to about 1:288, and find that most of the variation across loci of the ancestral mutation rate u is between 7.7*10 -4 and 3.5*10 -3. The proportion of males with access to matings per breeding season is estimated to about 21%. Chapter 4 is devoted to the estimation of migration rates between a large number of pairs of populations. Again, I use ABC for inference. Estimating all rates jointly comes with substantial methodological problems. Therefore, I assess if, by dividing the whole problem into smaller ones and assuming that those are approximately independent, more accuracy may be achieved overall. The net accuracy of the second approach increases with the number of migration rates. Applying that approach to microsatellite data from Alpine ibex, and accounting for the possibility that a model without migration could also explain the data, I find no evidence for substantial gene flow via migration, except for one pair of demes in one direction. While chapters 3 and 4 deal with neutral variation, in chapter 5 I investigate if an allele of the Major Histocompatibility Complex (MHC) has been under selection over the last ten generations. Short- and medium-term methods for detecting signals of selection are combined. For the medium-term analysis, I adapt a matrix iteration approach that allows for joint estimation of the initial allele frequency, the dominance coefficient, and the strength of selection. The focal MHC allele is shared with domestic goat, and an interesting side issue is if this reflects an ancestral polymorphism or is due to recent introgression via hybridization. I find most evidence for asymmetric overdominance (selection coefficient s: 0.974; equilibrium frequency: 0.125) or directional selection against the `goat' allele (s: 0.5) with partial recessivity. Both scenarios suggest a disadvantage of the `goat' homozygote, but differ in the relative fitness of the heterozygotes. Overall, two aspects play a dominating role in this thesis: the biological questions and the process of inference. They are linked, yet while the proximate motivation for the biological component is given by a specific system - the structured population of Alpine ibex in the Swiss Alps - the methods used and advanced here are fairly general and may well be applied in different contexts.

Full textAbstract:
This thesis is concerned with student migration to the UK. The research objectives of this study are to investigate the personal, familial and social processes pertaining to international student migration and to contribute to the theorization of migration. To further its research objectives the study adopts a grounded theory approach which allows students to voice the concerns, motives and influences pertaining to their migration actions and intentions. The method of the inquiry is qualitative and is based on individual, in-depth, interviews with Greek and Chinese students at the University of Sheffield. In order to interpret and analyse its findings, this research employs the work of Pierre Bourdieu and the Life-course approach on migration. Further, these two distinct bodies of work are combined into a theoretical framework able to further social scientific understanding of migration decision-making. This study brings forward the concept of an intended migration trajectory as a theoretical tool with the potential to enhance our understanding of the migration process. Student migration is found to be a response to the individual and familial needs and ambitions generated by the context in which agents move. Individual actions and intentions are part of an effort to further needs and ambitions in multiple spheres of activity in the best possible way. Migration is best described as a process in the sense that migration partly alters the context facing individuals and families and so contributes to a partial change in agents' needs, ambitions and, ultimately, migration intentions. Overall, this study accomplishes its objectives to investigate Greek and Chinese student migration to the UK and to further social scientists' theoretical understanding of 21st century migration flows.
