Η παρούσα έρευνα, πραγματεύεται το μεταναστευτικό φαινόμενο και ειδικότερα τη σημαντικότητα που έχει η γνώση της γλώσσας της χώρας υποδοχής για τους μετανάστες. Η έντονη παρουσία των μεταναστών στην Ελλάδα και οι δυσκολίες που αυτοί αντιμετωπίζουν στον κοινωνικό και εργασιακό τομέα, εξαιτίας της αδύναμης κοινωνικής τους θέσης, ήταν η αφορμή για την πραγματοποίηση της έρευνας. Η αναζήτηση των παραγόντων που θα μπορούσαν να βελτιώσουν την ένταξή τους στη χώρα έστρεψε το προσωπικό ενδιαφέρον στην μελέτη της εκμάθησης της γλώσσας της χώρας υποδοχής. Το μεθοδολογικό εργαλείο που χρησιμοποιήθηκε είναι η ημιδομημένη συνέντευξη και τα ερευνώμενα υποκείμενα είναι μετανάστες, ανεξαρτήτως νομικού καθεστώτος, που κατοικούν στην Ελλάδα. Αναλύοντας τα δεδομένα των συνεντεύξεων, συμπεραίνεται πως η επιρροή της γλώσσας είναι περιορισμένη, καθώς σχετίζεται κυρίως με προσωπικά οφέλη (όπως για παράδειγμα, η αύξηση της αυτοπεποίθησης του μετανάστη), και δεν βοηθά ουσιαστικά, όσο πιστεύεται, στη βελτίωση των συνθηκών ζωής του μετανάστη και την πληρέστερη ένταξή του. Επίσης, εκτός από το ζήτημα της ένταξης, παρατηρήθηκε πως ακόμη και η εκδοχή της γλώσσας που ο μετανάστης μαθαίνει να χρησιμοποιεί, συμβάλλει στην παγίωση της αρχικής του θέσης στην κοινωνία υποδοχής. Αυτό συμβαίνει, επειδή ο γλωσσικός κώδικας που αυτός χρησιμοποιεί διαφέρει από εκείνον της κυρίαρχης - αστικής τάξης, οπότε μιλάμε για κοινωνική αναπαραγωγή. / The present research analyses the immigration phenomenon and more specifically, the importance of the official language´s knowledge of the recipient country for the immigrants. The large presence of immigrants in Greece and the difficulties which they confront in social and labor brenches due to their weak social position, was the starting point of this research project. The search of the agents which could improve their integration in the country made me aim my personal interests into the field of language learning in the recipient country. Semi - structured interviews where used as the methodological tool of the research whose subjects were immigrants living in Greece, regardless of their legal status. By analyzing the results of the interviews, we come to the conclusion that the influence of the language is limited since it is related to personal profits (for example: increase of the immigrants self-confidence feeling) and essentially, does not boost, as it is believed, the immigrant´s life standards´ improvement and his full integration. Moreover, apart from the integration fact, the research also showed that the language stratum which the immigrant acquires and uses, contributes to the settlement of his initial social position in the recipient country. This occurs due to his usage of the language code, which differs from the one used by the dominant - middle class, so it is a question of social reproduction.

La présence de magmas en profondeur permet de contraindre des processus géologiques passés et actuels. Ces magmas (i.e. liquides silicatés) participent aux cycles géochimiques des éléments volatils comme vecteur de matière.Nous étudions deux éléments volatils complémentaires : l'iode (I), un halogène, et le xénon (Xe), un gaz rare. Leur système radioactif éteint 129I/129Xe (T1/2 = 15.7Ma) est utilisé pour dater les processus hadéens et la formation de l'atmosphère, issu de l'évolution d'un océan magmatique. Or on connait peu le comportement de l'iode et du xénon dans les magmas en profondeur à haute pression et température.Notre protocole expérimental vise l'étude de l'incorporation de l'iode et du xénon et de leur solubilité dans les magmas. Pour étudier l'incorporation, la structure des silicates liquides a été caractérisée par diffraction de rayons X avec des expériences in situ réalisées dans des cellules à enclumes de diamant et dans des presses Paris-Édimbourg. Les teneurs de solubilité de l'iode et du xénon ainsi que l'eau ont été mesurés par les méthodes PIXE et ERDA.À hautes pressions, l'iode possède une forte solubilité (quelques %pds) dans les magmas. Les résultats préliminaires sur son incorporation dans du basalte montrent que l'iode ne formerait pas des liaisons covalentes. À haute pression et température (T>300°C - P>1GPa), le xénon forme une liaison covalente Xe-O avec les oxygènes des anneaux de 6 tétraèdres SiO44-. Le xénon a une solubilité élevée dans les magmas (4pds% - 1600°C - 3.5GPa).Les modèles de datation et des cycles géochimiques de l'iode et du xénon doivent être revus en tenant compte de leur comportement différentiel dans les magmas. / The presence of magmas at depth helps to constrain past and actual geological processes. Magmas (i.e. silicate melts) participate in geochemical cycles of volatile elements, as vectors of chemical transfers. We study two complementary volatile elements: iodine (I), a halogen, and xenon (Xe), a noble gas. Their extinct 129I/129Xe isotopic system (half-life of 15.7Ma) is used to date Hadean processes and Earth’s atmosphere formation since the atmosphere originated from the Magma Ocean’s evolution. However, little is known about the behavior of both iodine and xenon in silicate melts at depth, under HT and HP conditions. Our experimental protocol aims at elucidating the incorporation process of xenon and iodine in silicate melts, and their solubility. To understand the incorporation of iodine and xenon in magmas, the structure of silicate melts was investigated by in situ diamond anvil cells and Paris-Edinburgh press experiments coupled with X-ray diffraction characterization. Iodine and xenon’s solubility, along with water content are obtained by PIXE and ERDA methods using a nuclear microprobe. At high pressure, iodine has a high solubility (about few wt.%) in magmas. Preliminary results on iodine incorporation in basaltic melt show an absence of covalent bond. At high pressure and temperature conditions (T>300°C – P>1GPa), xenon forms a Xe-O covalent bond with the oxygens of the 6-membered-rings of the melt network. Its solubility in silicate melts is also high (about 4wt.% in haplogranite melts at 1600°C and 3.5GPa). Considering the xenon and iodine differential behavior in melts at depth, a revision of dating models in xenon and iodine cycles must be considered.

The current proposed method for the long-term management of intermediate and high level radioactive waste in the UK is via geological disposal. It is known that redox sensitive elements such as uranium and neptunium will significantly contribute to the total waste inventory. Recently, studies have indicated that both U and Np can be stabilised by interaction with minerals. Over long periods of time (1000’s -10,000’s years) steel canisters that encase radioactive waste in geodisposal systems will undergo anaerobic corrosion, potentially leading to the release of radionuclides, including U and Np. Anaerobic corrosion will also result in the formation of a number of oxide phases, including iron (oxyhydr)oxides e.g. magnetite and green rust. The interaction of U and Np with such forming iron (oxyhydr)oxides may lead to the sequestering of radionuclides in the environment through a range of processes such as adsorption to a mineral surface and incorporation into a mineral structure. Therefore the interactions between iron (oxyhydr)oxides and radionuclides are important to determine their fate if potentially released within the wider environment. In this study, the fate of U(VI) and Np(V) when in contact with a range of iron (oxyhydr)oxides was considered. These systems were selected to help understand the detailed mechanisms that may occur between radionuclides and iron (oxyhydr)oxides. XRD and TEM were used to characterise mineralogy, whilst acid digestions determined the distribution of U within the mineral phase. Synchrotron based XAS was used to determine oxidation state, site geometry and local bonding environment of the radionuclides associated with the mineral phases. The data suggests that: U(V) is stabilised and incorporated in octahedral coordination into both the magnetite and green rust structure in a uranate-like coordination; with increasing U concentration mineral formation favours uraninite and Fe(III) (oxyhydr)oxides; the limit of U incorporation into magnetite is 0.45 mol % U ± 0.23; Np(V) is reduced to Np(IV) on the iron (oxyhydr)oxide surface forming a bidentate binuclear complex; and that upon reoxidation, Np(IV) is partially reoxidised back to Np(V) but not released back into solution. These results highlight the significance in understanding the mechanisms when both Np and U are in contact with iron (oxyhydr)oxides which can contribute towards site environmental clean-up and waste management in the nuclear industry.

A presente pesquisa apresenta uma análise laboratorial da adesividade e do comportamento mecânico de concretos asfálticos elaborados com agregados de granito e com ligante convencional (CAP 50/70) e ligante modificado por polímero (AMP CAP 60/85), priorizando os efeitos decorrentes da incorporação de dois tipos de cales. A primeira, denominada cal calcítica (com elevado teor de óxido de cálcio) é oriunda do Estado de Minas Gerais e, a segunda, denominada cal dolomítica, produzida no Estado do Rio Grande do Sul. Para a dosagem das seis misturas estudadas foi utilizada a metodologia Marshall, sendo posteriormente realizados ensaios de Resistência à Tração por Compressão Diametral, Módulo de Resiliência, Dano por Umidade Induzida (AASHTO T 283/89) e Resistência à Fadiga utilizando-se o ensaio de Tração indireta por compressão diametral, no modo tensão controlada. De posse dos resultados laboratoriais foi realizada uma análise elástico - linear, utilizando o Programa Computacional EVERSTRESS 5.0, e aplicado os resultados de deformação nos modelos obtidos em laboratório para as seis misturas analisadas. Considerando este critério, pode-se observar que os melhores resultados foram obtidos para as misturas elaboradas com ligante modificado. Quando empregado o ligante convencional evidenciou-se a melhora do comportamento da resistência à Fadiga das misturas que tiveram incorporação de cal (aumento de até 330% quando empregada cal calcítica e de até 348% quando empregada cal dolomítica), enquanto que quando preparadas com ligante modificado por polímero, a mistura que apresentou melhores resultados foi a elaborada sem incorporação de cal. Outro fato constatado e importante diz respeito a interação entre a cal, o ligante e o agregado granítico, já que diferentemente do esperado, a incorporação de cales não ocasionou resultados satisfatórios na adesividade. / This research shows a laboratory test of adhesiveness and the mechanical behavior of asphalt concrete prepared with granitic aggregate and conventional binder (CAP 50/70) and polymer-modified binder (AMP CAP 60/85), prioritizing the effects resulting from the merger of two types of limes. The first, called calcite lime (with high content of calcium oxide), comes from the Brazilian State of Minas Gerais; the second, the dolomitic lime, is produced in the State of Rio Grande do Sul. The Marshall method assessed the six mixtures studied; subsequently, Tensile Strength for Diametral Compression, Resilience Module, Damage Induced by Humidity (AASHTO T 283/89) and Resistance to Fatigue were tested by means of indirect traction by diametrical compression in controlled stress mode. A linear elastic analysis followed the laboratory results, using Computational Program EVERSTRESS 5.0; deformation results obtained in laboratory models for the six analyzed mixtures were applied. In accordance with this criterion, the best results point to asphalt mixtures prepared with modified binder. The use of conventional binder showed improvement in the fatigue resistance behavior of mixtures that take lime incorporation (increase of up to 330% with calcite lime, and up to 348% with dolomitic lime); however, when prepared with polymer-modified binder, the mixture that showed the best results did not have the addition of lime. Another noteworthy fact confirmed concerns the interaction amongst the lime, the binder and the granitic aggregate: unlike expected, the incorporation of limes did not convey satisfactory results in adhesiveness.

This thesis project examined underemployment at the state and national levels. Underemployment is the inability of highly skilled migrants with degrees from their home countries to enter the workforce in the receiving country. Pending and enacted legislation was analyzed at the state level to determine in which ways the state of Oregon can implement similar policies to effectively incorporate underemployed immigrants into the state workforce. This project utilized primary data sources at the state and federal level, migrant interviews were used as illustrations of the barriers that exist for underemployed migrants, and secondary data sources from the fields of economics, social sciences, political sciences, and population studies were utilized to provide an understanding of how underemployment is addressed at the national level. Overall, my research found underemployed professional migrants are greatly underutilized, which translates into missed economic opportunities for individual migrants and for the United States as a whole.

Comme l’indique le titre de cette étude, notre travail se situe dans le prolongement de celui de Franck, et plus précisément de sa thèse déployée dans son livre, Chair et Corps : sur la phénoménologie de Husserl. Dans ce livre, Franck a démontré clairement le fondement dernier de la phénoménologie de Husserl, en disant que dans la mesure où la chair est définie par Husserl comme « auto-affection pure », cette chair ne peut pas se constituer comme un corps. Notre travail est un essai pour éprouver la phénoménologie de Henry, à partir de cette objection adressée à Husserl par Franck : l’impossibilité de l’incorporation de la chair. Notre question est donc la suivante : comment l’incorporation est-elle possible pour Henry, dans la mesure où, pour lui, l’auto-affection de la chair est pure. Notre travail sera conduit par cette seule question. Cependant, ce dont il s’agit ici ne peut pas être une simple interprétation de la philosophie de Henry. S’il est vrai que la phénoménologie de Husserl est un essai qui, en désirant « la phénoménologie comme science rigoureuse », cherche le fondement indiscutable de la philosophie, notre question touche ce fondement même, c’est-à-dire, le commencement de la philosophie. Lorsque nous interrogeons Henry sur le problème auquel est conduit inévitablement Husserl, cela nous conduit à poser la question du fondement dernier de la philosophie, à savoir, la question de son commencement qui, à vrai dire, est un commencement qui a toujours et déjà commencé. / As like the title of this study, our work is a continuation of the Franck’s work, specifically, which he deployed in his book Flesh and body : on the phenomenology of Husserl. In his analysis on the phenomenology of Husserl, Franck demonstrates that the flesh cannot be embodied, if it is defined as “pure auto-affection.” Our work expands on this thesis : the impossibility of emboyding the flesh, and attempts to examine the phenomenology of Michel Henry. The most important question is : how can Michel Henry explain an embodiment of flesh to the extent that he defines the flesh as pure auto-affection. However, what is involved here cannot be a simple interpretation of the Henry’s philosophy. While it is true that Husserl’s phenomenology is a test that, desiring "phenomenology as rigorous science", seeks the indisputable foundation of philosophy, we are asking for this foundation of philosophy that means the beginning of philosophy, when we ask Henry about the problem which inevitably leads Husserl. So, our question is the ultimate foundation of philosophy, the question of its beginning which, indeed, is a beginning that has always already begun.
