Extreme dry spell detection and climatology over the Mediterranean Basin during the wet season
The E-OBS precipitation gridded data set v.10.0 is used to detect very long dry spell (VLDS) events over the entire Mediterranean Basin for the 1957–2013 period, during the wet season (September to April). The main objective is to characterize these events as climatic objects, in terms of location, spatial extent, duration, and temporal variability. In this study, 76 VLDS events were detected in the Mediterranean Basin and grouped into four spatial patterns: scattered localized (with 25 events), northeast Mediterranean (11 events), West Mediterranean (15 events), and southeast Mediterranean (25 events). Each pattern shows seasonality in events. Most of the scattered localized, northeast, an…
Effects of Intranasal Oxytocin on Emotion Regulation in Insecure Adolescents: Study Protocol for a Double-Blind, Randomized Controlled Trial
Background: Emotional dysregulation and impaired attachment are potential contributors to the development of psychopathology in adolescence. This raises the question of whether oxytocin (OT), the paradigmatic “attachment hormone,” may be beneficial in such contexts. Recent evidence suggests that intranasal administration of OT increases affiliative behavior, including trust and empathy. OT may also facilitate social reciprocity by attenuating the stress response to interpersonal conflict. To date, few studies have investigated the effects of intranasal oxytocin (IN-OT) on neurophysiological emotion regulation strategies in healthy adolescents, particularly during parent-adolescent interacti…
DACORD - Computer-Assisted Drawing of Archaeological Pottery (the CADAPtable system)
International audience
Computer-assisted orientation and drawing of archaeological pottery.
Archaeologists spend considerable time orienting and drawing ceramic fragments by hand for documentation, to infer their manufacture, the nature of the discovery site and its chronology, and to develop hypotheses about commercial and cultural exchanges, social organisation, resource exploitation, and taphonomic processes. This study presents a survey of existing solutions to the time-consuming problem of orienting and drawing pottery fragments. Orientation is based on the 3D geometry of pottery models, which can now be acquired in minutes with low-cost 3D scanners. Several methods are presented: they are based on normal vectors, or circle fittings, or profile fittings. All these methods see…
How do adolescents regulate distress according to attachment style? A combined eye-tracking and neurophysiological approach.
According to attachment theory, attachment representations influence emotion regulation (ER) across the lifespan. However, research into attachment-related ER in adolescence is still scarce. The aim of this study was to assess attachment-related ER using a multimodal approach, relying on behavioral and neurophysiological parameters. Attachment styles in eighty-one adolescents were assessed with the Attachment Style Interview (ASI). A distress-then-comfort paradigm based on visual stimuli (the Besancon Affective Picture Set-Adolescents) was employed to "activate" then "deactivate" the attachment system. Gaze and neurophysiological parameters of ER strategies were assessed using eye-tracking …
