Quel âge post-séculier ? Religions, démocraties, sciences

Que signifient les discours actuels en faveur du « post-séculier » ? Et pourquoi faudrait-il en finir avec l'âge séculier ? Qui l'exige ou le demande ? Quels sont les événements qui le requièrent ? Ces dernières années, un débat sur la place de la religion dans les démocraties libérales s'est engagé dans le monde intellectuel. Si certains ont parlé d'un Âge séculier et d'autres d'une « société post-séculière », c'est parfois la dynamique même de sécularisation de l'espace public qui semble avoir été remise en cause. Plus profondément, ce sont les rapports entre religions, sciences et démocraties qui ont été questionnés. En faisant délibérément usage de ces termes au pluriel - pour indiquer qu'il existe différentes formes de religion, plusieurs genres de sciences et plusieurs conceptions de la démocratie - les contributions rassemblées dans ce volume entendent sonder ces rapports et cette pluralité. Le lecteur y trouvera la traduction française de plusieurs interventions de John Dewey sur l'anti-naturalisme et la religion, des contributions de pragmatistes contemporains et des enquêtes sur le rôle public de la foi ou sur la mise en cause de l'autorité épistémique des sciences, aussi bien aux États-Unis, qu'en Europe et en Afrique du nord.

Psychological distress in health sciences college students and its relationship with academic engagement

Objective: To determine the prevalence of psychological distress and its relationship with academic engagement (absorption, dedication and vigor), sex and degree among students from four public universities. Method: A non-experimental,comparative correlational, quantitative investigation without intervention. Study population: 1840 nursing and physical therapy students. The data collection tool used was a questionnaire. Results: A 32.2% prevalence of psychological distress was found in the subjects; a correlation between vigor and psychological distress was found for all of the subjects and also for women. High absorption and dedication scores and low psychological distress scores predicted higher vigor scores. Conclusion: The risk of psychological distress is high, especially for women. Women seem to have a higher level of psychological distress than men. Vigor, energy and mental resilience positively influence psychological distress and can be a vehicle for better results during the learning and studying process.







Chemiluminescent DNA probes: evaluation and usefulness in forensic cases.

Five phosphatase-labelled oligonucleotide probes were evaluated in respect to their sensitivity, with the help of an optimized chemiluminescent protocol, for DNA-VNTR polymorphism determination. Their usefulness for the identification of biological traces is illustrated with casework examples.

Intégration de méthodes de data mining dans le renseignement criminel : analyse par des structures issues de la théorie des graphes dans le profilage des stupéfiants

Data mining can be defined as the extraction of previously unknown and potentially useful information from large datasets. The main principle is to devise computer programs that run through databases and automatically seek deterministic patterns. It is applied in different fields of application, e.g., remote sensing, biometry, speech recognition, but has seldom been applied to forensic case data. The intrinsic difficulty related to the use of such data lies in its heterogeneity, which comes from the many different sources of information. The aim of this study is to highlight potential uses of pattern recognition that would provide relevant results from a criminal intelligence point of view. The role of data mining within a global crime analysis methodology is to detect all types of structures in a dataset. Once filtered and interpreted, those structures can point to previously unseen criminal activities. The interpretation of patterns for intelligence purposes is the final stage of the process. It allows the researcher to validate the whole methodology and to refine each step if necessary. An application to cutting agents found in illicit drug seizures was performed. A combinatorial approach was done, using the presence and the absence of products. Methods coming from the graph theory field were used to extract patterns in data constituted by links between products and place and date of seizure. A data mining process completed using graphing techniques is called ``graph mining''. Patterns were detected that had to be interpreted and compared with preliminary knowledge to establish their relevancy. The illicit drug profiling process is actually an intelligence process that uses preliminary illicit drug classes to classify new samples. Methods proposed in this study could be used \textit{a priori} to compare structures from preliminary and post-detection patterns. This new knowledge of a repeated structure may provide valuable complementary information to profiling and become a source of intelligence.
