In this paper we study student interaction in English and Swedish courses at a Finnish university. We focus on language choices made in task-related activities in small group interaction. Our research interests arose from the change in the teaching curriculum, in which content and language courses were integrated at Tampere University of Technology in 2013. Using conversation analysis, we analysed groups of 4-5 students who worked collaboratively on a task via a video conference programme. The results show how language alternation has different functions in 1) situations where students orient to managing the task, e.g., in transitions into task, or where they orient to technical problems, and 2) situations where students accomplish the task. With the results, we aim to show how language alternation can provide interactional opportunities for language learning. The findings will be useful in designing tasks in the future.

BACKGROUND: Suffering from a chronic disease or disability (CDD) during adolescence can be a burden for both the adolescents and their parents. The aim of the present study is to assess how living with a CDD during adolescence, the quality of parent-adolescent relationship (PAR) and the adolescent's psychosocial development interact with each other. METHODS: Using the Swiss Multicenter Adolescent Survey on Health 2002 (SMASH02) database, we compared adolescents aged 16-20 years with a CDD (n = 760) with their healthy peers (n = 6493) on sociodemographics, adolescents' general and psychosocial health, interparental relationship and PAR. RESULTS: Bivariate analyses showed that adolescents with a CDD had a poorer psychosocial health and a more difficult relationship with their parents. The log-linear model indirectly linked CDD and poor PAR through four variables: two of the adolescents' psychosocial health variables (suicide attempt and sensation seeking), the need for help regarding difficulties with parents and a highly educated mother that acted as a protective factor, allowing for a better parent-adolescent with a CDD relationship. CONCLUSION: It is essential for health professionals taking care of adolescents with a CDD to distinguish between issues in relation with the CDD from other psychosocial difficulties, in order to help these adolescents and their parents deal with them appropriately and thus maintain a healthy PAR.

Reversed phase liquid chromatography (RPLC) coupled to mass spectrometry (MS) is the gold standard technique in bioanalysis. However, hydrophilic interaction chromatography (HILIC) could represent a viable alternative to RPLC for the analysis of polar and/or ionizable compounds, as it often provides higher MS sensitivity and alternative selectivity. Nevertheless, this technique can be also prone to matrix effects (ME). ME are one of the major issues in quantitative LC-MS bioanalysis. To ensure acceptable method performance (i.e., trueness and precision), a careful evaluation and minimization of ME is required. In the present study, the incidence of ME in HILIC-MS/MS and RPLC-MS/MS was compared for plasma and urine samples using two representative sets of 38 pharmaceutical compounds and 40 doping agents, respectively. The optimal generic chromatographic conditions in terms of selectivity with respect to interfering compounds were established in both chromatographic modes by testing three different stationary phases in each mode with different mobile phase pH. A second step involved the assessment of ME in RPLC and HILIC under the best generic conditions, using the post-extraction addition method. Biological samples were prepared using two different sample pre-treatments, i.e., a non-selective sample clean-up procedure (protein precipitation and simple dilution for plasma and urine samples, respectively) and a selective sample preparation, i.e., solid phase extraction for both matrices. The non-selective pretreatments led to significantly less ME in RPLC vs. HILIC conditions regardless of the matrix. On the contrary, HILIC appeared as a valuable alternative to RPLC for plasma and urine samples treated by a selective sample preparation. Indeed, in the case of selective sample preparation, the compounds influenced by ME were different in HILIC and RPLC, and lower and similar ME occurrence was generally observed in RPLC vs. HILIC for urine and plasma samples, respectively. The complementary of both chromatographic modes was also demonstrated, as ME was observed only scarcely for urine and plasma samples when selecting the most appropriate chromatographic mode.

Internationally, policies for attracting highly-skilled migrants have become the guidelines mainly used by the Organisation for Economic Co-operation and Development (OECD) countries. Governments are implementing specific procedures to capture and facilitate their mobility. However, all professions are not equal when it comes to welcoming highly-skilled migrants. The medical profession, as a protective market, is one of these. Taking the case of non-EU/EEA doctors in France, this paper shows that the medical profession defined as the closed labour market, remains the most controversial in terms of professional integration of migrants, protectionist barriers to migrant competition and challenge of medical shortage. Based on the path-dependency approach, this paper argues that non-EU/EEA doctors' issues in France derive from a complex historical process of interaction between standards settled in the past, particularly the historical power of medical corporatism, the unexpected long-term effects of French hospital reforms of 1958, and budgetary pressures. Theoretically, this paper shows two significant findings. Firstly, the French medical system has undergone a series of transformations unthinkable in the strict sense of a path-dependence approach: an opening of the medical profession to foreign physicians in the context of the Europeanisation of public policy, acceptance of non-EU/EEA doctors in a context of medical shortage and budgetary pressures. Secondly, there is no change of the overall paradigm: significantly, the recruitment policies of non-EU/EEA doctors continue to highlight the imprint of the past and reveal a significant persistence of prejudices. Non-EU/EEA doctors are not considered legitimate doctors even if they have the qualifications of physicians which are legitimate in their country and which can be recognised in other receiving countries.

Avec cette thèse de doctorat nous proposons une réflexion transversale concernant les relations entre infrastructures de transport et développement territorial dans des espaces dits « intermédiaires ». Le concept d'espace intermédiaire, relativement nouveau en géographie, est conçu en fonction d'une double approche : celle des infrastructures où les espaces intermédiaires constituent des zones de transit obligées entre des pôles urbains hiérarchiquement supérieurs (par rapport une échelle horizontale) et celle des frontières où les espaces intermédiaires constituent des territoires de coopération entre différents niveaux politico-institutionnels (par rapport à une échelle verticale). Cette problématique de recherche est traitée aussi bien du point de vue théorique qu'avec des études de cas portant sur les effets des nouvelles infrastructures de transports dans la région transfrontalière insubrique (entre le Canton du Tessin et la Lombardie). L'objectif visé est de défendre un scénario d'organisation spatiale polycentrique à plusieurs niveaux comme solution pour le développement durable et cohérent de ces espaces intermédiaires. Ainsi, pour le « niveau macro », nous proposons une analyse des changements d'accessibilité spatiale et des potentiels de développement territorial pour les agglomérations concernées par la mise en service du nouveau tunnel ferroviaire de base du Monte Ceneri (TBC) et de la nouvelle ligne Lugano/Como-Mendrisio-Varese-Malpensa (FMV) à l'horizon 2020. Pour le « niveau meso », nous analysons les effets de la nouvelle ligne FMV en termes de potentiel de densification polycentrique autours des gares ferroviaires. Pour le « niveau micro », nous proposons une analyse sur les comportements de mobilité ainsi que des améliorations ciblées du système de transport pour la ville de Mendrisio visant à promouvoir le développement polycentrique de cette commune. De plus, un système d'analyse permettant de mettre en lien les divers facteurs explicatifs dans l'analyse des relations entre les nouvelles infrastructures de transport et les effets sur la mobilité et le développement territorial est également élaboré et testé dans notre recherche. -- With this Ph.D. thesis we investigate the relationship between transport infrastructures and territory development inside the so called "in-between spaces". The idea of "in-between space", relatively novel in geography, is the formal outcome of a double approach: the one of the infrastructures, saying that these spaces can be described as areas of constrained transit between urban centres of superior hierarchical level (on a horizontal scale), and the one of the borders, stating that in-between spaces are areas of cooperation between various political-institutional levels. The above mentioned research issues are deepened both at theoretical and empirical level, being the latter based on field studies of the cross-boundary Western-Lombard area (between the Swiss canton of Ticino and the Italian region of Lombardy). This research pursues the goal of defending the argument that a multi-level polycentric spatial scenario can be a possible solution fora sustainable development of the above described in- between areas. From a "macro" perspective, what we submit here is an analysis on the expected changes in spatial accessibility and on the potential territorial development for the built-up areas influenced by the construction of the new train tunnel of the Monte Ceneri (TBC) and of the new railway line Lugano/Como-Mendrisio-Varese-Malpensa (FMV). At a "meso" level we analyse the effects exerted by the new FMV line taking into account the potential densification of the areas surrounding the railway stations. Finally, at a "micro" level, we analyse the mobility behaviours in the town of Mendrisio and we propose some possible improvements to the local public transport system, with the scope to promote a polycentric development of this municipality. Moreover, we developed and tested an analytic system able to define the existing links between the various explaining factors characterizing the relationship between new transport infrastructures and effects on mobility. -- With this Ph.D. thesis we investigate the relationship between transport infrastructures and territory development inside the so called "in-between spaces".

In this study we analize the application of the reflective learning during initial formation mathematics teachers. This model is based on the sociocultural theories of the human learning and assumes that the interaction and the contrast make possible the coconstruction and the active reconstruction of knowledge.In order to make the study, it was left from a sample of 29 teaching students. The qualitative analysis allowed to identify factors that facilitate the incorporation of the reflective learning in university teaching, as well as the degree of effectiveness of this model to learn to teach mathematics

OBJECTIVES: Polypharmacy is one of the main management issues in public health policies because of its financial impact and the increasing number of people involved. The polymedicated population according to their demographic and therapeutic profile and the cost for the public healthcare system were characterised. DESIGN: Cross-sectional study. SETTING: Primary healthcare in Barcelona Health Region, Catalonia, Spain (5 105 551 inhabitants registered). PARTICIPANTS: All insured polymedicated patients. Polymedicated patients were those with a consumption of ≥16 drugs/month. MAIN OUTCOMES MEASURES: The study variables were related to age, gender and medication intake obtained from the 2008 census and records of prescriptions dispensed in pharmacies and charged to the public health system. RESULTS: There were 36 880 polymedicated patients (women: 64.2%; average age: 74.5±10.9 years). The total number of prescriptions billed in 2008 was 2 266 830 (2 272 920 total package units). The most polymedicated group (up to 40% of the total prescriptions) was patients between 75 and 84 years old. The average number of prescriptions billed monthly per patient was 32±2, with an average cost of 452.7±27.5. The total cost of those prescriptions corresponded to 2% of the drug expenditure in Catalonia. The groups N, C, A, R and M represented 71.4% of the total number of drug package units dispensed to polymedicated patients. Great variability was found between the medication profiles of men and women, and between age groups; greater discrepancies were found in paediatric patients (5-14 years) and the elderly (≥65 years). CONCLUSIONS: This study provides essential information to take steps towards rational drug use and a structured approach in the polymedicated population in primary healthcare.

Trust in inter-organizational collaborative relationships has attracted substantial research interest among academics and practitioners. Previous studies have concentrated on the benefits of trust to business outcomes and economic performance, as it is considered to be a source of competitive advantage. Despite this increased level of interest, there is no consensus, much less overall agreement, about how it should be conceptualized or about the number of dimensions it incorporates. On the inter-organizational level there is an obvious challenge in defining both the trusting party and the objects of trust. Thus, the notion of trust as an under-theorized and poorly understood phenomenon still holds. Hence, the motivation of this study was fuelled by the need to increase our knowledge and understanding of the role and nature of trust in inter-organizational collaborative relationships. It is posited that there is a call for more understanding about its antecedents and consequences, as well as about the very concept in inter-organizational collaborative relationships. The study is divided into two parts. The first part gives a general overview, and the second part comprises four research publications. Both qualitative and quantitative research methodology is utilized. A multi-method research design was used because it provides different levels of data and different perspectives on the phenomenon. The results of this study reveal that trust incorporates three dimensions on both the individual and the organizational level: capability, goodwill, and self-reference. Trust develops from the reputation and behavior of the trusted party. It appears from this study that trust is clearly directed towards both individual boundary spanners and the counterpart company itself – i.e. not only to one or the other. The trusting party, on the other hand, is always an individual, and not the organization per se. Trust increases collaboration benefits and lowers collaboration drawbacks, thus having a positive effect on relationship performance. The major contribution of this study lies in uncovering the critical points and drawbacks in prior research and thereby in responding to the highlighted challenges. The way in which these challenges were addressed offers contributions to three major issues in the emerging theory of trust in the inter-organizational context: firstly, this study clarifies the trustor-trustee discussion; secondly, it conceptualizes trust as existing on both individual and organizational levels; and thirdly, it provides more information about the antecedents of trust and the ways in which it affects relationship performance.

An extensive literature suggests a link between executive functions and aggressive behavior in humans, pointing mostly to an inverse relationship, i.e., increased tendencies toward aggression in individuals scoring low on executive function tests. This literature is limited, though, in terms of the groups studied and the measures of executive functions. In this paper, we present data from two studies addressing these issues. In a first behavioral study, we asked whether high trait aggressiveness is related to reduced executive functions. A sample of over 600 students performed in an extensive behavioral test battery including paradigms addressing executive functions such as the Eriksen Flanker task, Stroop task, n-back task, and Tower of London (TOL). High trait aggressive participants were found to have a significantly reduced latency score in the TOL, indicating more impulsive behavior compared to low trait aggressive participants. No other differences were detected. In an EEG-study, we assessed neural and behavioral correlates of error monitoring and response inhibition in participants who were characterized based on their laboratory-induced aggressive behavior in a competitive reaction time task. Participants who retaliated more in the aggression paradigm and had reduced frontal activity when being provoked did not, however, show any reduction in behavioral or neural correlates of executive control compared to the less aggressive participants. Our results question a strong relationship between aggression and executive functions at least for healthy, high-functioning people.
