Dyadic Variability in Mother-Adolescent Interactions: Developmental Trajectories and Associations with Psychosocial Functioning

Dyadic variability is considered to be a key mechanism in the development of mother-adolescent relationships, and low levels of dyadic flexibility are thought to be associated with behavior and relationship problems. The present observational study examined heterogeneity in the development of dyadic variability in mother-adolescent interactions and associations with psychosocial functioning. Dyadic variability refers to the range of emotional states during interactions of mother-adolescent dyads. During five annual home visits, 92 mother-adolescent dyads (M age T1 = 13; 65.2 % boys) were videotaped while discussing a conflict, and they completed several questionnaires on adolescents’ aggressive behavior and adolescents’ and mothers’ perceived relationship quality. Two types of dyads were distinguished: low variability dyads (52 %) and high decreasing variability dyads (48 %). Over time, high decreasing variability dyads were characterized by a broader emotional repertoire than low variability dyads. Moreover, these two dyad types had distinct developmental patterns of psychosocial adjustment. Over time, high decreasing variability dyads showed lower levels of adolescents’ aggressive behavior, and higher levels of perceived relationship quality than low variability dyads. These findings suggest that over time more dyadic variability is associated with less adjustment problems and a more constructive development of the mother-adolescent relationship. Adaptive interactions seem to be characterized by a wider range of emotional states and mothers should guide adolescents during interactions to express both positive and negative affect. Observing the dyadic variability during mother-adolescent interactions can help clinicians to distinguish adaptive from maladaptive mother-adolescent dyads.     

A Self-Activation Hypothesis of Affective Reactions to Fair and Unfair Events: Evidence for Supraliminal and Subliminal Processes

Building and extending on justice theories and work on self-regulation, the current paper proposes a self-activation hypothesis of affective reactions to fair and unfair events, stating that in circumstances in which people’s selves are activated, stronger affective reactions to fair and unfair events are more likely, compared to circumstances in which people’s selves are not or less strongly activated. Findings of two experiments indeed show that simply activating the self (supraliminally or even subliminally) amplifies affective reactions to fair and unfair procedures (Experiment 1) and fair and unfair outcomes (Experiment 2). These findings thus reveal the important role of activation of the self for understanding fairness reactions. In the discussion, we note the relevance of our self-activation hypothesis for insights into different accounts formulated in the justice domain.     

IGNA's original LIMS: A complete traceability of administrative and analytic processes for forensic cases

IGNA is the first French laboratory for forensic DNA analysis. IGNA LIMS was developed from the software Microsoft Dynamics NAV which is an ERP (Enterprise Resource Planning) with a real opened solution for specific development and compatible with a lot of Microsoft applications.Thanks to the LIMS, we assure the traceability of analysis and also administrative process (traceability of letters, quotes or phone calls for each case and registration of actions to be done in a case (call for results …)).For one penal case, we can associate one or more sealed items. The DNA expert indicates the analysis to do on each piece (biological fluid detection, type of extraction, nuclear or mitochondrial DNA analysis …).During the technical process, samples automatically pass from a step to the next. Technicians indicate all the information needed for traceability (consumables lot number, used robots …).At the end of the process, the DNA expert validates his results, which are then directly transferred to the final report.Development of the IGNA LIMS from Microsoft Dynamics NAV allows us to use all specific applications of an ERP such as purchases, marketing, sales, etc. and to assure computerization of all our process, from quote to analysis report.
