International texts recognise the buyer's right to the repair or replacement if the goods do not conform with the contract, and at the same time, establish exceptions to their application and certain rules of protection for the seller (Art. 46 CISG, Art. 7.2.3 UNIDROIT Principles of International Commercial Contracts, Art.9:102 PECL and Arts. 4:202 y 4:204 (1) PEL S). This approach is a result of a compromise between civil law systems and the common law and it has been widely extended to the regulation of consumer sales over the last decade (Art. 3.3 of the Directive 1999/44/CE, Art. III.-3:302 DCFR, Art. 26 of the proposal for a Directive on Consumer Rights). These norms regulate the different ways of requiring the fulfilment of a contractual obligation from a new paradigm which has little to do with a need to protect the weak consumer which governed the origins of consumer policy in the European Community. Now the idea of the consumer who shall behave economically efficiently prevails in Art. 3.3 of the Directive 1999/44/CE, a norm which is clearly influenced by the international texts and whose transposing into the national legislation of Member States has created important problems for traditional dogmas. In this sense there are still some unclear issues, such as the possibility of replacing in sales of goods of specific nature or second-hand goods, some aspects on the exercise of repair and replacement, and, even, their use as primary remedies rather than a reduction in price or a rescission of the contract. With regard to this, in England the possibility of offering the consumer free choice between these measures if the goods do not conform with the contract has been raised. This is far from the principle of pacta sunt servanda and is clearly contrary to the economic approach of the proposal for a Directive on Consumer Rights. Up to now Spain has limited itself to implementing Art. 3.3 Directive 1999/44/CE into its legal system in almost literal terms and the case law on the issue has completely turned out to be insufficient. By contrast with Germany, the Spanish legislator has not extended the application of the rules of repair and replacement of Directive 1999/44/CE to nonconsumer sales, even though two draft bill proposals along these lines presented by the General Commission for Codifying (“Comisión General de Codificación”), the last one being in January, 2009

Se entrenó a unas ratas a encontrar una plataforma invisible definida por una configuración de dos objetos en la mitad de los ensayos y por una segunda configuración de dos objetos en la otra mitad. Los objetos estaban espaciados alrededor del borde de la piscina. Las dos configuraciones se presentaron con la misma frecuencia cada día, entremezcladas semi-al azar. En el Experimento 1, las configuraciones de las ratas fueron A y B (configuración 1), y B y C (configuración 2). B era un objeto común a ambas configuraciones. Al final de esta fase los animales recibieron ensayos de prueba en los que se colocaba a una rata en la piscina sin la plataforma y se registraba el tiempo que pasaba en el cuadrante de la plataforma. Los animales tuvieron ensayos de prueba con las configuraciones del entrenamiento, con los objetos por separado, y con una nueva configuración, A y C (una prueba de integración). Tanto ante las configuraciones del entrenamiento como en presencia de B, las ratas pasaron una cantidad de tiempo sustancial buscando la plataforma en el cuadrante de la plataforma; no se obtuvo ningún otro efecto en las otras pruebas. En el Experimento 2 se introdujeron varios cambios metodológicos y se replicaron los principales resultados del Experimento 1. Concluimos que tras un entrenamiento configuracional como el empleado, la navegación de las ratas hacia una plataforma invisible estuvo controlada por un aprendizaje elemental, por B.

Rodrigo, Chamizo, McLaren, & Mackintosh (1997) demonstrated the blocking effect in a navigational task using a swimming pool: rats initially trained to use three landmarks (ABC) to find an invisible platform learned less about a fourth landmark (X) added later than did rats trained from the outset with these four landmarks (ABCX). The aim of the experiment reported here was to demonstrate unblocking using a similar procedure as in the previous work. Three groups of rats were initially trained to find an invisible platfom in the presence of three landmarks: ABC for the Blocking and Unblocking groups and LMN for the Control group. Then, all animals were trained to find the platform in the presence of four landmarks, ABCX. In this second training, unlike animals in the Blocking group to which only a new landmark (X) was added in comparison to the first training, the animals in the Unblocking group also had a change in the platform position. In the Control group, both the four landmarks and the platform position were totally new at the beginning of this second training. As in Rodrigo et al. (1997) a blocking effect was found: rats in the Blocking group learned less with respect to the added landmark (X) than did animals in the Control group. However, rats in the Unblocking group learned about the added landmark (X) as well as did animals in the Control group. The results are interpreted as an unblocking effect due to a change in the platform position between the two phases of training, similarly to what is normal in classical conditioning experiments, in which a change in the conditions of reinforcement between the two training phases of a blocking design produce an attenuation or elimination of this effect. These results are explained within an error-correcting connectionist account of spatial navigation (McLaren, 2002).

La escolarización de los niños que proceden de la inmigración, especialmente la extracomunitaria, comporta dificultades que, aunque a veces se niegan, son evidentes para cualquier persona que trabaja en el mundo de la educación. Así, la creciente diversidad étnica y lingüística, y otros fenómenos, como la incorporación tardía, es vista por bastantes profesoras y profesores como una "carga" suplementarias en su quehacer educativo diario. De hecho, en la concepción clásica del trabajo escolar, la consideración de un aumento de las dificultades cuando aumenta la diversidad siempre ha estado presente y, nos guste o no, nuestro sistema educativo, como la mayoría de sistemas educativos, sigue siendo bastante clásico. Sin embargo, es de justicia señalar que las modificaciones , incluidas las innovaciones, que los sistemas educativos han sufrido en el tiempo han ido de la mano de adaptarlos a la creciente diversidad social que se iba incorporando. En los últimos años, está afirmación debe relativizarse, al menos en el sentido que toma en el texto. Así, en muchos países occidentales, las actuales reformas educativas buscan su adaptabilidad sobre la base de la segregación

In my PhD dissertation, I have examined a group of people of Scandinavian origin received by Ospizio dei Convertendi. This group has been hitherto largely unknown to historical research. The Ospizio was an institute founded by the Oratorian Congregation in Rome in 1673 to provide religious instruction and material aid to both recent and aspirant converts to Roman Catholicism. My research traces the profile of converts and a typology of motives, examining different factors which influenced the conversion process. I show that the key factors were often of a social rather than a religious nature. Moreover, I have analyzed the hospice in the context of Counter-Reformation charity as well. In terms of numbers, the Scandinavians formed a somewhat marginal yet not insignificant group within the Roman hospice. Out of a total of 2203 guests received between 1673 and 1706, 4.6 % were Scandinavians: 74 Swedes (including Finland and Livonia) and 27 Danes (including Norway). They came from a rigorously Protestant region which reacted to Catholicism with severe legislative measures. Converts to Catholicism risked confiscation of their goods, expulsion or even capital punishment. Since both Sweden and Denmark were practically impenetrable to Catholicism at the time and clandestine missionary attempts often failed before they had even properly started, the Roman Catholic Church shifted its interest towards Northerners arriving in Rome, a preferred destination for young noblemen, artists and migrant craftsmen. The material related to Ospizio dei Convertendi, conserved in the Vatican archives, is a scarcely known yet unusually rich source, not only for the religious history of our continent, but also for social history and the study of migration in early modern Europe. It contains a wealth of information about members of the subordinate classes, of their travels and lives in Europe. The profile delineated in these documents is of individuals who had a wide range of different professions and different aspirations. These documents encompass a vast social spectrum that was highly mobile on a continent which by that time had become pluriconfessional. Therefore, these migrants faced the complex religious reality in their everyday life. The principal corpus of my research consists of two types of manuscript sources created for administrative and in a way also for apologetic purposes of the Roman Catholic Church. My starting point is the Primo registro generale of Ospizio dei Convertendi. This is a volume in which the following information about each guest was registered: name, nationality, city of origin, age, sex, profession, confession professed before converting, date of arrival, departure, abjuration and baptism. Typically, the convert was male, originating from Stockholm or Copenhagen, from 21 to 30 years of age. The biggest occupational groups in descending order were soldiers, noblemen, craftsmen and sailors. Thus the data reflects a multiform reality of interurban and long distance migration, ideals regarding the education of young noblemen and gentry as well as the need of European armies to hire foreign mercenaries in their various campaigns. Against this background the almost total absence of women is hardly surprising: there is only one woman in the material I have studied. The second main source, Nota degl’ospiti ricevuti e spese fatte per essi, sheds more light on the choices of the converts, their motivations and their lives outside Scandinavia before reaching Rome. This narrative material permits an analysis which completes but also goes far beyond the columns of the Institute’s general register. This material consists of reports written by Catholic priests based on an interview conducted upon each guest’s arrival. The material frequently includes information on what the converts would do following their departure from the Institute as well. These sources have a specific narrative form and contain short biographies, list reasons for converting and information about the journey from the North to the Mediterranean - a journey which in many cases took several years. Moreover, they show that certain unorthodox practices such as calling on the saints and pleading for help from them were not uncommon in the Protestant popular religion. The recording of information on conversions from Protestantism to Catholicism reflects both religious and social interest on the part of the receiving institute. The information obtained was used for the purposes of religious teaching, for finding adequate ways of inserting the convert into Italian society so that he could earn a living, and to find effective methods to convert others with a similar cultural and geographical background. The stories recorded were based on interviews with the newly-arrived, information obtained from a travel companion or fellow countrymen, or from written documents the aspirant converts carried with them. These sources illustrate, although sometimes in rather simplified ways, the circumstances and motivations which were relevant to the choice of changing one’s confession. In addition, I have examined petitions addressed to the hospice and other Roman authorities in order to get financial aid. These petitions were written by Italian scrittori, and they contain certain conventions and topoi of presenting the conversion with the purpose of improving the chances of obtaining financial aid. It is through these filters, which may seem initially almost invisible, that the remote voice of the converts reaches us. The results of the analysis are particularly interesting because they disagree with some of the principal conclusions of previous work on the subject. First, earlier research has focused almost exclusively on the conversions of noblemen, and has argued, second, that the Queen Christina of Sweden was the driving force behind their change of confession. The sources examined for this dissertation present a profile of long-distance migrants, many of them members of the subordinate classes, who were looking for ways to make their living in Europe. These people had in many cases left their country of origin several years earlier and not for religious reasons, so, crucially, we are not dealing with confessional migration in these cases. Rather, conversion was a complex process, intricately tied up with strategies of survival, integration and upward social mobility. At the same time, while these components are significant on their own right, they do not necessarily point to the absence of motivations of a more clearly religious nature.

Poly(D,L-lactide), PDLLA, is a polymer with potential applications in medical, environmental, and pharmaceutical areas. Despite its versatility, the hydrophobicity limits its applications. To overcome this problem, one strategy is the preparation of blends with hydrophilic polymers such as poly(vinylpyrrolidone), PVP. In this study, we report the preparation and characterization of blends based on PDLLA and PVP and the biodegradation studies by the Sturm test. It was observed that the components of the blends PDLLA/PVP are thermodynamically immiscible, however the biodegradation is faster than that of pure PDLLA.

Poly(3-hydroxybutyrate), PHB, is a polymer with broad potential applications because of its biodegradability and biocompatibility. However, its high crystallinity is a limiting factor for many applications. To overcome this drawback, one strategy currently employed involves the reduction of the molecular weight of PHB with the concomitant formation of end-functionalized chains, such as those obtained via glycolysis. The glycolysis of PHB can be catalyzed by acid, base, or organometallic compounds. However, to our knowledge, there are no reports regarding PHB glycolysis catalyzed enzymatically. Among the major types of enzymes used in biocatalysis, the lipases stand out because they have the ability to catalyze reactions in both aqueous and organic media. Thus, in this study, we performed the enzymatic glycolysis of PHB using the lipase Amano PS (Pseudomonas cepacia) with ethane-1,2-diol (ethylene glycol) as the functionalizing agent. The results indicated that the glycolysis was successful and afforded hydroxyl-terminated oligomeric PHB polyols. Nuclear magnetic resonance spectra of the products showed characteristic signals for the terminal hydroxyl groups of the polyols, while thermogravimetric and differential scanning calorimetry analyses confirmed an increase in the thermal stability and a decrease in the crystallinity of the polyols compared with the starting PHB polymer, which were both attributed to the reduction in the molecular weight due to glycolysis.

This review reports the preparation and characterization of bionanocomposites based on biodegradable polymers reinforced with cellulose nanocrystals (CNC) described in the literature. The outstanding potential of cellulose nanocrystals as reinforcement fillers of biodegradable polymers is presented with an emphasis on the solution casting process, which is an appropriate method to investigate the physico-chemical effects of the incorporation of CNC into the polymeric matrices. Besides solution casting, other small scale methods such as electrospinning and layer-by-layer are also covered.

Bionanocomposites derived from poly(L-Lactide) (PLLA) were reinforced with chemically modified cellulose nanocrystals (m-CNCs). The effects of these modified cellulose nanoparticles on the mechanical and hydrolytic degradation behavior of polylactide were studied. The m-CNCs were prepared by a method in which hydrolysis of cellulose chains is performed simultaneously with the esterification of hydroxyl groups to produce modified nanocrystals with ester groups. FTIR, elemental analysis, TEM, XRD and contact angle measurements were used to confirm and characterize the chemical modifications of the m-CNCs. These bionanocomposites gave considerably better mechanical properties than neat PLLA based on an approximately 100% increase in tensile strength. Due to the hydrophobic properties of the esterified nanocrystals incorporated into a polymer matrix, it was also demonstrated that a small amount of m-CNCs could lead to a remarkable decrease in the hydrolytic degradation rate of the biopolymer. In addition, the m-CNCs considerably delay the degradation of the nanocomposite by providing a physical barrier that prevents the permeation of water, which thus hinders the overall absorption of water into the matrix. The results obtained in this study show the nanocrystals can be used to reinforce polylactides and fine-tune their degradation rates in moist or physiological environments.

In the present dissertation, multilingual thesauri were approached as cultural products and the focus was twofold: On the empirical level the focus was placed on the translatability of certain British-English social science indexing terms into the Finnish language and culture at a concept, a term and an indexing term level. On the theoretical level the focus was placed on the aim of translation and on the concept of equivalence. In accordance with modern communicative and dynamic translation theories the interest was on the human dimension. The study is qualitative. In this study, equivalence was understood in a similar way to how dynamic, functional equivalence is commonly understood in translation studies. Translating was seen as a decision-making process, where a translator often has different kinds of possibilities to choose in order to fulfil the function of the translation. Accordingly, and as a starting point for the construction of the empirical part, the function of the source text was considered to be the same or similar to the function of the target text, that is, a functional thesaurus both in source and target context. Further, the study approached the challenges of multilingual thesaurus construction from the perspectives of semantics and pragmatics. In semantic analysis the focus was on what the words conventionally mean and in pragmatics on the ‘invisible’ meaning - or how we recognise what is meant even when it is not actually said (or written). Languages and ideas expressed by languages are created mainly in accordance with expressional needs of the surrounding culture and thesauri were considered to reflect several subcultures and consequently the discourses which represent them. The research material consisted of different kinds of potential discourses: dictionaries, database records, and thesauri, Finnish versus British social science researches, Finnish versus British indexers, simulated indexing tasks with five articles and Finnish versus British thesaurus constructors. In practice, the professional background of the two last mentioned groups was rather similar. It became even more clear that all the material types had their own characteristics, although naturally not entirely separate from each other. It is further noteworthy that the different types and origins of research material were not used to represent true comparison pairs, and that the aim of triangulation of methods and material was to gain a holistic view. The general research questions were: 1. Can differences be found between Finnish and British discourses regarding family roles as thesaurus terms, and if so, what kinds of differences and which are the implications for multilingual thesaurus construction? 2. What is the pragmatic indexing term equivalence? The first question studied how the same topic (family roles) was represented in different contexts and by different users, and further focused on how the possible differences were handled in multilingual thesaurus construction. The second question was based on findings of the previous one, and answered to the final question as to what kinds of factors should be considered when defining translation equivalence in multilingual thesaurus construction. The study used multiple cases and several data collection and analysis methods aiming at theoretical replication and complementarity. The empirical material and analysis consisted of focused interviews (with Finnish and British social scientists, thesaurus constructors and indexers), simulated indexing tasks with Finnish and British indexers, semantic component analysis of dictionary definitions and translations, coword analysis and datasets retrieved in databases, and discourse analysis of thesauri. As a terminological starting point a topic and case family roles was selected. The results were clear: 1) It was possible to identify different discourses. There also existed subdiscourses. For example within the group of social scientists the orientation to qualitative versus quantitative research had an impact on the way they reacted to the studied words and discourses, and indexers placed more emphasis on the information seekers whereas thesaurus constructors approached the construction problems from a more material based solution. The differences between the different specialist groups i.e. the social scientists, the indexers and the thesaurus constructors were often greater than between the different geo-cultural groups i.e. Finnish versus British. The differences occurred as a result of different translation aims, diverging expectations for multilingual thesauri and variety of practices. For multilingual thesaurus construction this means severe challenges. The clearly ambiguous concept of multilingual thesaurus as well as different construction and translation strategies should be considered more precisely in order to shed light on focus and equivalence types, which are clearly not self-evident. The research also revealed the close connection between the aims of multilingual thesauri and the pragmatic indexing term equivalence. 2) The pragmatic indexing term equivalence is very much context-depended. Although thesaurus term equivalence is defined and standardised in the field of library and information science (LIS), it is not understood in one established way and the current LIS tools are inadequate to provide enough analytical tools for both constructing and studying different kinds of multilingual thesauri as well as their indexing term equivalence. The tools provided in translation science were more practical and theoretical, and especially the division of different meanings of a word provided a useful tool in analysing the pragmatic equivalence, which often differs from the ideal model represented in thesaurus construction literature. The study thus showed that the variety of different discourses should be acknowledged, there is a need for operationalisation of new types of multilingual thesauri, and the factors influencing pragmatic indexing term equivalence should be discussed more precisely than is traditionally done.

Denna vårdvetenskapliga avhandling syftar till att avtäcka och belysa en vårdande och helande dimension vid existentiellt lidande patienters möten med bildkonst inom vårdkontext. Kunskapssökandet sker i två studier. Den första (studie I) är en ikonografi sk tolkning av konstnären Matthias Grünewalds (ca 1460–1528) senmedeltida altarskåpsmålningar. I studien uttolkas lidandets uttryck och narrativa budskap samt symboliska gestaltningar av vårdande och helande i valda delar av detta s.k. Isenheimaltares bildprogram. Tolkningen utgår från rekonstruktionen av altarskåpets ursprungskontext, det medeltida Isenheimklostret, där svårt sjuka och döende patienter vårdades. I studie två (II) fortsätter sökandet i den moderna hospicevårdens kontext med hjälp av en kvalitativ intervjustudie som utforskar patienters meningsskapande vid möten med självvald bildkonst (oljemålningar och akvareller av fi nländska konstnärer som donerats till det sjukhus där intervjustudien gjordes). Forskningsansatsen är inspirerad av Hans-Georg Gadamers (1901–2002) hermeneutik. Vidare används några nyare tolkningsteoretiska ansatser inom bildkonstens område. Forskningens tolkningsresultat visar att bildkonsten har potentialer såväl på ett miljöestetiskt plan som på en djupare individuell symbolnivå. Som designkomponent i vårdmiljöns rumsliga gestaltning bygger bildkonsten in estetiska, etiska och andliga kvaliteter utifrån tidsmässiga och kulturella koder. I den medeltida klostervårdens kontext sammanföll bildkonstens dekorativa betydelse med andliga och helande syften. När det gäller självvalda konstverk i den moderna vårdkontexten bidrar de till det enskilda patientrummets atmosfär på ett unikt sätt utifrån patientens personlighet och behov. På en fördjupad mötesnivå, i samspel med bildens symboliska funktion, sker en inlevelsemässig förfl yttning in i bildens värld. Betraktarens inlevelse aktiveras till en transcenderande rörelse som går bortom det faktiska rummets och den reella tidens gränser. Vid resor i konstens bildvärld spelas minnesvärda händelser upp från det förgångna, men även framtiden kommer betraktaren till mötes. I en existentiell livssituation söker människan i konstverkets bildinnehåll efter symbolisk mening som kan ge svar på lidandets frågor. Bilderna iscensätter då helande motbilder som utgör korrektiv i symboliska former när olika existentiella förluster hotar. När livet förbleknats av sjukdom besvarar bildvärlden den lidandes blick med lysande violer som blommar upp, ger livskraft och bekräftar personens värdighet mitt i det förvissnande människolivet. När ångest och otrygghet nalkas inbjuds betraktaren till besök i landskap som utvidgar sjukhusrummets väggar mot hemgårdens trygghet. Där livet hotas av förgänglighet tar bildvärlden människan med sig till naturens eviga återfödelse. Upplevelsen av att vara delaktig i ett större och heligt sammanhang öppnar vägen ut ur lidandets avskurenhet. I medeltidens vårdkontext erbjöd den sakrala bilden en kollektiv och helande Symbolon som genom sin representationskraft synliggjorde det osynliga. Vid bildmöten i den moderna hospicevårdens kontext var det naturteman som gläntade på dörren till ”det hemliga rummet i djupet av hjärtat”. Forskningen antyder att även om meningsskapandet i ett bildmöte är avhängigt tidsepok, betraktarens förförståelse och kulturella kontext samt typen av bilder kan bildsymboliken, generellt förstådd som den saknade formen eller det saknade livssammanhanget, framvisa en helande och hoppingivande ordning i lidandets kaos.

Maahanmuuttajien määrä on Suomessa merkittävämmin lisääntynyt vasta 1990- ja 2000-luvuilla. Vuonna 2010 Suomessa asui lähes 170 000 ulkomaan kansalaista. Tavallisimmin Suomeen muutetaan avioliiton, paluumuuton tai pakolaisuuden vuoksi. Pieni, joskin kasvava joukko muuttaa työn tai opiskelun vuoksi. Myös kansalaisuuksien, koulutustaustojen, ammattien jne. kirjo muuttajien joukossa on suuri. Ulkomaan kansalaisten lisääntyessä Suomessa on jouduttu kohtaamaan monenlaisia maahanmuuttoon liittyviä haasteita, joista työllistymiseen liittyvät kysymykset eivät ole vähäisimpiä. Tutkimuksessa tarkastellaan lähtömaassaan korkeakoulututkinnon suorittaneiden maahanmuuttajien työllistymistä ja työuran alkua Suomessa. Tutkimuksen tarkoituksena on selvittää, miten korkeakoulutetut maahanmuuttajat ovat Suomessa työllistyneet, minkälaisia heidän työuriensa alut ovat Suomessa olleet ja miten he ovat onnistuneet uudessa maassa hyödyntämään lähtömaassa hankkimaansa koulutusta. Lisäksi tutkimuksessa tarkastellaan, miten maahanmuuttajien lähtömaan erilaiset elämäntilanteet, olosuhteet ja valinnat ovat vaikuttaneet työuran muotoutumiseen Suomessa. Tutkimuksen aineisto muodostuu kysely- sekä haastatteluaineistosta. Kyselyaineiston (n=99) tarkoituksena on luoda määrällistä kuvaa korkeakoulutettujen maahanmuuttajien työllistymisestä Suomessa. Numerotietojen taakse jää kuitenkin näkymättömiin tieto maahanmuuttajien yksilöllisistä kokemuksista liittyen työllistymiseen ja työuran muotoutumiseen uudessa maassa. Toisena aineistona hyödynnettävän elämäkerrallisen haastatteluaineiston (n=20) kautta on mahdollista tehdä näkyväksi ne tutkittavien yksilölliset työ- ja koulutusuraan liittyvät valinnat, joita maahanmuuttajat ovat tehneet niin lähtömaassa kuin Suomessa sekä ne tilanteet ja olosuhteet, joissa tutkittavat ovat lähtömaassa eläneet ja joiden pohjalta he ovat tulleet Suomeen ja Suomen työmarkkinoille. Aineistoissa mukana olevat maahanmuuttajat olivat pääosin avioliiton, paluumuuton sekä pakolaisuuden vuoksi Suomeen tulleita. Vain muutama oli tullut työn vuoksi. Maahanmuuttajien työmarkkina-asemaa selitetään usein maahanmuuttajien resursseilla, kuten kielitaidolla, koulutuksella, työkokemuksella, sosiaalisten suhteiden ja verkostojen laadulla ja määrällä jne. Myös maahanmuuttajiin kohdistuvilla syrjivillä ja ennakkoluuloisilla asenteilla on keskeinen merkitys työllistymisessä. Koulutuksen ollessa yksi keskeisimmistä työmarkkina-asemaa määräävistä tekijöistä, tulisi koulutettujen maahanmuuttajien sijoittua hankitun tutkinnon oikeuttamiin tehtäviin. Tutkimuksessa kuitenkin havaittiin, että työllistyminen oli maahanmuuttajilla vaikeaa hyvästä koulutuksesta huolimatta. Kyselyaineistoon vastanneista vain muutama (6 %) oli työssä heti Suomeen muuttovuoden lopussa, kolme vuotta Suomessa asuttuaan työssä oli runsas kolmannes (35 %) ja aineistonkeruuhetkellä eli vuonna 2004 työssä oli 38 % vastaajista. Työsuhteet olivat tutkittavilla useimmiten määräaikaisia ja kestoltaan lyhyitä. Lisäksi työurat koostuivat runsaasta työttömyydestä sekä koulutukseen osallistumisesta. Myönteistä kuitenkin oli, että mikäli korkeakoulutetut maahanmuuttajat onnistuivat Suomessa työllistymään, vastasi työ usein joko kokonaan tai ainakin osittain hankittua korkeakoulututkintoa. Korkeakoulutettujen maahanmuuttajien työuran alut Suomessa voidaan tyypitellä kolmeen ryhmään, joista kukin jakaantui vielä kahteen alaryhmään siten, että kaiken kaikkiaan saatiin kuusi erilaista työuran alun tyyppiä: koulutusta vastaava vakaa ja vakiintuva ura, koulutusta osittain vastaava sekaura ja laskeva ura sekä koulutusta vastaamaton sisääntuloura ja työttömän ura . Haastatteluaineiston kautta tarkastellaan korkeakoulutettujen maahanmuuttajien yksilöllisiä elämänuria lähtien liikkeelle korkeakoulutettujen maahanmuuttajien lähtömaassa tekemistä ura- ja ammatinvalinnoista jatkuen Suomeen muuton kautta aina työuran muotoutumiseen Suomessa. Haastatteluja toisistaan erottelevina keskeisinä teemoina olivat toisaalta pärjääminen Suomessa ja suomalaisilla työmarkkinoilla toisaalta elämän muotoutuminen lähtömaassa ja nimenomaan siellä tehdyt ura- ja ammatinvalinnat ja niihin liittyvät kokemukset ja elämäntilanteet. Näiden kriteerien pohjalta aineisto jakaantui kolmeen ryhmään, jotka nimettiin pärjääjiksi, harhailijoiksi ja sinnittelijöiksi. Pärjääjien kertomukset muotoutuivat tietyllä tavalla myönteisen kehän kautta: niin lähtömaassa tehdyt ammatinvalinnat kuin työuran muotoutuminen Suomessa tapahtuivat suhteellisen vaivattomasti. Useimmiten työt Suomessa vastasivat lähtömaassa hankittua koulutusta. Omiin uravalintoihin oltiin myöhemmin myös tyytyväisiä. Harhailijoille oman paikan löytyminen oli puolestaan hankalampaa. Leimallista tälle ryhmälle oli tietynlainen valintojen vaikeus sekä tyytymättömyys omiin aikaisemmin tehtyihin ratkaisuihin. Jotkut harmittelivat nuorena tekemiään uravalintoja niin, että päättivät Suomessa hankkia kokonaan uuden ammatin. Muutto Suomeen merkitsi useimmille ammatillisen aseman laskua. Sinnittelijät kertoivat jo lähtökohdiltaan kahteen muuhun ryhmään nähden hyvin erilaista tarinaa. Tämän ryhmän lähes koko elämä lähtömaassa oli sodan ja levottomuuksien sävyttämää. Tämä näkyi myös ammatinvalinnassa: opiskelupaikka oli saatettu valita esimerkiksi sen perusteella, missä oli milloinkin turvallista opiskella. Myös Suomeen muutto erosi kahdesta aikaisemmasta ryhmästä, sillä lähtö entisestä kotimaasta oli tapahtunut usein hyvinkin yllättäen vailla etukäteissuunnittelua tilanteiden kärjistyttyä nopeasti. Suomessa työelämään pääseminen oli kaikille sinnittelijöille vaikeaa ja haastatteluhetkellä useilla vielä hyvin alkutekijöissä. Hyväkään koulutus ei aina takaa maahanmuuttajille työtä uudessa maassa, sillä hankittua tutkintoa ja osaamista ei ole helppo siirtää maasta toiseen. Pahimmassa tapauksessa vieraassa maassa suoritettu korkeakoulututkinto voi kokonaan mitätöityä uudessa maassa ja korkeakoulututkinnon myötä hankittu osaaminen menettää täysin arvonsa. Kyse on niin yksilön kuin yhteiskunnankin resurssien tuhlaamisesta tilanteessa, jossa maassa pysyvästi asuvat koulutetut maahanmuuttajat työskentelevät tavalla tai toisella koulutustaan vastaamattomissa epävakaissa töissä, työmarkkinoiden laitamilla tai ovat kokonaan työmarkkinoiden ulkopuolella.
