Cette étude esquisse, sur la base d'un grand échantillon représentatif et longitudinal de couples vivant en Suisse et du point de vue des femmes ayant répondu à l'enquête, un tableau de l'évolution des problèmes conjugaux rencontrés au cours des différentes phases de la vie familiale. Le processus de dégradation de la relation est reconstitué à partir de 2 mesures faites dans un intervalle de 5 ans. La genèse des difficultés conjugales est considérée à travers le prisme des transitions familiales, en particulier la naissance des enfants, leur entrée à l'école et leur départ du domicile parental. L'analyse révèle le potentiel déstabilisateur de ces transitions pour le couple. Les bouleversements de l'équilibre relationnel évoluent, dans certains cas, vers un cumul de difficultés qui envahissent l'espace conjugal pour déboucher sur une situation rapidement inextricable.

Background: To enhance our understanding of complex biological systems like diseases we need to put all of the available data into context and use this to detect relations, pattern and rules which allow predictive hypotheses to be defined. Life science has become a data rich science with information about the behaviour of millions of entities like genes, chemical compounds, diseases, cell types and organs, which are organised in many different databases and/or spread throughout the literature. Existing knowledge such as genotype - phenotype relations or signal transduction pathways must be semantically integrated and dynamically organised into structured networks that are connected with clinical and experimental data. Different approaches to this challenge exist but so far none has proven entirely satisfactory. Results: To address this challenge we previously developed a generic knowledge management framework, BioXM™, which allows the dynamic, graphic generation of domain specific knowledge representation models based on specific objects and their relations supporting annotations and ontologies. Here we demonstrate the utility of BioXM for knowledge management in systems biology as part of the EU FP6 BioBridge project on translational approaches to chronic diseases. From clinical and experimental data, text-mining results and public databases we generate a chronic obstructive pulmonary disease (COPD) knowledge base and demonstrate its use by mining specific molecular networks together with integrated clinical and experimental data. Conclusions: We generate the first semantically integrated COPD specific public knowledge base and find that for the integration of clinical and experimental data with pre-existing knowledge the configuration based set-up enabled by BioXM reduced implementation time and effort for the knowledge base compared to similar systems implemented as classical software development projects. The knowledgebase enables the retrieval of sub-networks including protein-protein interaction, pathway, gene - disease and gene - compound data which are used for subsequent data analysis, modelling and simulation. Pre-structured queries and reports enhance usability; establishing their use in everyday clinical settings requires further simplification with a browser based interface which is currently under development.

The topic of conjugal quality provides an empirical illustration of the relevance of the configurational perspective on families. Based on a longitudinal sample of 1,534 couples living in Switzerland drawn from the study "Social Stratification, Cohesion and Conflict in Contemporary Families", we show that various types of interdependencies with relatives and friends promote distinct conflict management strategies for couples as well as unequal levels of conjugal quality. We find that configurations characterized by supportive and non-interfering relationships with relatives and friends for both partners are associated with higher conjugal quality, while configurations characterized by interference are associated with lower conjugal quality.

We evaluated 25 protocol variants of 14 independent computational methods for exon identification, transcript reconstruction and expression-level quantification from RNA-seq data. Our results show that most algorithms are able to identify discrete transcript components with high success rates but that assembly of complete isoform structures poses a major challenge even when all constituent elements are identified. Expression-level estimates also varied widely across methods, even when based on similar transcript models. Consequently, the complexity of higher eukaryotic genomes imposes severe limitations on transcript recall and splice product discrimination that are likely to remain limiting factors for the analysis of current-generation RNA-seq data.

How much would output increase if underdeveloped economies were to increase their levels of schooling? We contribute to the development accounting literature by describing a non-parametric upper bound on the increase in output that can be generated by more schooling. The advantage of our approach is that the upper bound is valid for any number of schooling levels with arbitrary patterns of substitution/complementarity. Another advantage is that the upper bound is robust to certain forms of endogenous technology response to changes in schooling. We also quantify the upper bound for all economies with the necessary data, compare our results with the standard development accounting approach, and provide an update on the results using the standard approach for a large sample of countries.

Mathematical methods combined with measurements of single-cell dynamics provide a means to reconstruct intracellular processes that are only partly or indirectly accessible experimentally. To obtain reliable reconstructions, the pooling of measurements from several cells of a clonal population is mandatory. However, cell-to-cell variability originating from diverse sources poses computational challenges for such process reconstruction. We introduce a scalable Bayesian inference framework that properly accounts for population heterogeneity. The method allows inference of inaccessible molecular states and kinetic parameters; computation of Bayes factors for model selection; and dissection of intrinsic, extrinsic and technical noise. We show how additional single-cell readouts such as morphological features can be included in the analysis. We use the method to reconstruct the expression dynamics of a gene under an inducible promoter in yeast from time-lapse microscopy data.

A localização do arquipélago de Cabo Verde e as suas características biogeográficas conferem-lhe um especial interesse no domínio da Ecologia Marinha. Todavia, o conhecimento da composição dos ecossistemas costeiros desta região é incipiente, especialmente no que concerne as comunidades subtidais de macroinvertebrados bentónicos. Entre Agosto e Outubro de 2007, foram amostrados oito locais em redor da ilha de São Vicente. Em cada um desses locais recolheram-se fragmentos do substrato, de onde se contou um total de 4032 indivíduos, pertencentes a 81 espécies diferentes. Calculou-se o valor de índices de diversidade (Entropia de Shannon e Índice de Gini-Simpson) e o número real de espécies que cada um representava. Ao comparar os valores obtidos constataram-se diferenças entre estações e entre valores dos dois índices para o mesmo local. Com o intuito de agrupar as estações prospectadas de acordo com o número de indivíduos recolhidos de cada espécie identificada, elaborou-se um dendrograma e realizou-se uma análise de componentes principais. As estações consideradas para este estudo não mostraram diferenças significativas no que diz respeito à composição das suas comunidades subtidais de macroinvertebrados bentónicos em termos de grandes grupos taxonómicos ou grupos funcionais. Assume-se que as estações diferem apenas por discrepâncias pontuais.
