Research question. Students face many school and living difficulties which alter health status and favour substance use which were assessed in this study among university students from France, Poland and Romania. Methods. In total 934 French, 480 Polish, and 195 Romanian students from the Universities of Metz, Iaşi, and Silésie, completed a self-administred questionnaire. The data were analyzed using adjusted odds ratios (OR) and variance analysis taking age and sex into account, vs. French. Results. Mean age 20 (SD = 2) years. Female represented 58% French and 80% Polish/Romanian. Although most students were satisfied with their university integration (81-97%), many students had deteriorated heath status compared with the period before the university (13-22%), suffered from tiredness (11-85%), nervousness (42-56%), sleep disorders (19-48%), financial difficulty (15-39%), and being alone (8-23%). Were also common increasing tobacco use (15-32%), alcohol use every day (15-40%), tranquilizer pill use (1-6%), hashish/marijuana use (2-42%), suicide thinking (15-19%), and frequent consultation of health professionals (7-30%). Bad heath status was more frequent among French and Romanian overall, and suicide thinking among Polish. Higher PSS-14 and GHQ-12 scores among Polish compared with their French counterparts who used more hashish/marijuana. Satisfied social support was similar between the three groups. Conclusion. A better guidance for those who are in need of adapted mental health care seem nevertheless recommended to support them through their university success. [less ▲]

In this paper, we model the formation of innovation networks as they emerge from bilateral decisions. In contrast to much of the literature, here firms only consider knowledge production, and not network issues, when deciding on partners. Thus, we focus attention on the effects of the knowledge and information regime on network formation. The effectiveness of a bilateral collaboration is determined by cognitive, relational, and structural embeddedness. Innovation results from the recombination of knowledge held by the partners to the collaboration, and its success is determined in part by the extent to which firms’ knowledge complement each other. Previous collaborations (relational embeddedness) increase the probability of a successful collaboration, as does information gained from common third parties (structural embeddedness). Repeated alliance formation creates a network. Two features are central to the innovation process: how firms pool their knowledge resources, and how firms derive information about potential partners. When innovation is decomposable into separate subtasks, networks tend to be dense; when structural embeddedness is important, networks become cliquish. For some regions in this parameter space, small worlds emerge. Key Words: networks; innovation; knowledge; collaborative R&D; embeddedness [less ▲]

We model knowledge diffusion in a population of agents situated on a network, interacting only over direct ties. Some agents are by nature traders, others are by nature "givers": traders demand a quid pro quo for information transfer; givers do not. We are interested in efficiency of diffusion and explore the interplay between the structure of the population (proportion of traders), the network structure (clustering, path length and degree distribution), and the scarcity of knowledge. We find that at the global level, trading (as opposed to giving) reduces efficiency. At the individual level, highly connected agents do well when knowledge is scarce, agents in clustered neighbourhoods do well when it is abundant. The latter finding is connected to the debate on structural holes and social capital. [less ▲]

The cognitive, emotional and motivational inhibition of highly gifted underachievers has become recently a topic of interest for researchers in clinical psychology and psychopathology. In this context the authors wanted to test whether a computerized adaptive test in mathematics could help unblocking the achievement motivation of those students. The main features and principles of construction of the test are described. The results of an exploratory study which was undertaken with 123 students belonging to the second class of a secondary school, 35 of which were highly gifted, stretches the interest of the integration of a CAT into the global treatment procedures of the motivational deficit of highly gifted underachievers.

The aim was to assess the relationships between social and material deprivation and the use of tobacco, excessive alcohol and psychotropic drugs by both sexes and in various age groups. Greater knowledge concerning these issues may help public health policy-makers design more effective means of preventing substance abuse. Methods: The sample comprised 6,216 people aged ≥ 15 years randomly selected from the population in northeastern France. Subjects completed a post-mailed questionnaire covering socio-demographic characteristics, occupation, employment, income, smoking habit, alcohol abuse and "psychotropic" drug intake (for headache, tiredness, nervousness, anxiety, insomnia). A deprivation score (D) was defined by the cumulative number of: low educational level, manual worker, unemployed, living alone, nationality other than western European, low income, and non-home-ownership. Data were analysed using adjusted odds ratios (ORa) computed with logistic models. Results: Deprivation was common: 37.4% of respondents fell into category D = 1, 21.2% into D = 2, and 10.0% into D ≥ 3. More men than women reported tobacco use (30.2% vs. 21.9%) and alcohol abuse (12.5% vs. 3.3%), whereas psychotropic drug use was more common among women (23.8% vs. 41.0%). Increasing levels of deprivation were associated with a greater likelihood of tobacco use (ORa vs. D = 0: 1.16 in D = 1, 1.49 in D = 2, and 1.93 in D ≥ 3), alcohol abuse (1.19 in D = 1, 1.32 in D = 2, and 1.80 in D ≥ 3) and frequent psychotropic drug intake (1.26 in D = 1, 1.51 in D = 2, and 1.91 in D ≥ 3). These patterns were observed in working/other non-retired men and women (except for alcohol abuse in women). Among retired people, deprivation was associated with tobacco and psychotropic drug use only in men. Conclusion: Preventive measures should be designed to improve work conditions, reduce deprivation, and help deprived populations to be more aware of risk and to find remedial measures. [less ▲]

L'analyse des situations de lecture conjointe et auto-initiée par des premiers lecteurs en situation multilingue contribue au développement de nouvelles perspectives sur la nature sociale des processus de lecture et de leur constitution langagière en interaction. Partant de l'analyse séquentielle des pratiques discursives établies par les co-lecteurs, le présent article identifie et discute trois éléments constitutifs qui permettent l'accomplissement du processus de lecture conjointe ainsi que la construction d'un objet de lecture partagée. L'analyse des processus de lecture partagée met en lumière des dimensions socio-cognitives situées, impliquées dans les (inter-)actions de lecture, complétant ainsi les questionnements récents autour des approches adaptées pour une analyse des littéracies en développement.

The southeastern Po Plain is affected by high natural and anthropogenic subsidence. The area is well suited to test the application of an observational strategy which combines different techniques to extract information on the spatial and temporal variability of the subsidence. The simultaneous availability, at a few stations, of several geodetic observation techniques such as Global Positioning System (GPS), gravity, and Interferometric Synthetic Aperture Radar (InSAR) allows for validation of the individual time series. The combination takes advantage of the complementary strengths of each technique by overcoming the limitations inherent in each single technique alone. The combination of velocities derived from the GPS and gravity data, further complemented by the results of the InSAR Permanent Scatterers technique, allows us to monitor continuously, in space and time, vertical crustal movements. This high-density information is of major importance for understanding the processes responsible for the observed deformation. Here long-term trends were derived, enabling us to map the behavior of subsidence (even exceeding 20 mm/yr) with high spatial resolution in the southeastern Po Plain. The uplifting behavior of the Apennines chain bordering the Po Plain is identified together with a narrow zone separating the contrasting vertical crustal movements.
