Perceived major experiences of discrimination, ethnic group, and risk of psychosis in a six-country case-control study
2021
AbstractBackgroundPerceived discrimination is associated with worse mental health. Few studies have assessed whether perceived discrimination (i) is associated with the risk of psychotic disorders and (ii) contributes to an increased risk among minority ethnic groups relative to the ethnic majority.MethodsWe used data from the European Network of National Schizophrenia Networks Studying Gene-Environment Interactions Work Package 2, a population-based case−control study of incident psychotic disorders in 17 catchment sites across six countries. We calculated odds ratios (OR) and 95% confidence intervals (95% CI) for the associations between perceived discrimination and psychosis using mixed-…
“Ageism” Is Associated With Self-Reported Multidimensional Frailty in Community-Dwelling Older Subjects: A Population-Based Study
2022
Ageism is a stereotyping, prejudice and discrimination against people, based on age. Ageism may impact the quality of life and the care of older people, a problem that can be greater when the older person is “frail.” However, few studies explored the role of frailty as a factor related to ageism. The aim of this study was to assess the association between perceived age discrimination (PAD), i.e., ageism, and multidimensional frailty in a cohort of community-dwelling older adults. We enrolled 1,337 community-dwelling subjects over-65 years that filled out a structured questionnaire to collect psycho-socio-economic and behavioral information. Multidimensional frailty was assessed by the SELFY…
Chlorine as a Discriminant Element to Establish the Provenance of Central Mediterranean Obsidians
2020
Abstract Chlorine is a minor element present in obsidians in quantities greater than in average igneous rocks. The chlorine concentration in obsidians is generally low, of the order of tenths of wt %, but it exhibits an appreciable differentiation among geological sources. Despite these characteristics, chlorine has rarely been taken into consideration as a possible indicator of obsidian provenance and it does not appear in the chemical analytical tables accompanying the geochemical characterisation of obsidian samples. In this work, after an overview of chlorine geochemistry and cycle, we present thirty-one new electron microprobe (EPMA) analyses, including Cl, of geologic obsidians sample…
Migranti e lotta alla povertà. La Corte costituzionale nega il reddito di cittadinanza ai titolari del permesso di soggiorno per ricerca di un'occupa…
2022
Il commento analizza la recente sentenza n. 19/2022 della Corte costituzionale, in cui il Giudice delle leggi ha ritenuto costituzionalmente legittima la previsione legislativa, che subordina alla titolarità del permesso di soggiorno di lungo periodo l’ottenimento del reddito di cittadinanza per i migranti extracomunitari. The essay analyses the recent Italian constitutional court ruling (no. 19/2022), that deems constitutional social security law, which subordinates the granting of minimum income guaranteed to the ownership of permanent residence permit for non-EU citizens.
Formes éducationnelles plurielles : des mondes à part ? L'exemple par l'offre scolaire quadruple à Djibouti
2012
A l'heure où le " vivre ensemble " se réalise au travers d'une meilleure connaissance des formes empruntées par l'altérité, cette communication se propose d'aborder l'offre scolaire quadruple en place à Djibouti. Deux grands modèles éducatifs coexistent : un modèle éducatif de type universaliste (école catholique, école publique affiliée au fait colonial) visant la réussite économique inspirée historiquement par les réalités du monde occidental et un modèle éducatif de type communautaire (école coranique, madrasa) visant la cohésion sociale et culturelle par les traditions orientales musulmanes. Après avoir interrogé l'importance de ces modèles culturels dans le choix de scolarisation des f…
Weed detection by aerial imagery : toward weed management by UAV
2016
The agricultural framework aims to reduce pesticide use on fields. Weed management, which is highly herbicide consuming, became a great issue. In order to develop a weed management service using UAV, this PhD dissertation studies how to adapt the acquisition system (UAV + multispectral camera) developed by AIRINOV to detect weeds in row crops. The acquisition chain was modeled to assess some of its parameters (optical filters and spatial resolution) impact on weed detection quality. Orthoimages and orthorectified images were created using a multispectral camera (4 to 8 filters) with 6 mm to 6 cm spatial resolutions. Several weed location methods were specifically developed to study multispe…
Informal musical activities are linked to auditory discrimination and attention in 2-3-year-old children: an event-related potential study
2012
The relation between informal musical activities at home and electrophysiological indices of neural auditory change detection was investigated in 2-3-year-old children. Auditory event-related potentials were recorded in a multi-feature paradigm that included frequency, duration, intensity, direction, gap deviants and attention-catching novel sounds. Correlations were calculated between these responses and the amount of musical activity at home (i.e. musical play by the child and parental singing) reported by the parents. A higher overall amount of informal musical activity was associated with larger P3as elicited by the gap and duration deviants, and smaller late discriminative negativity r…
Hippocampal theta activity is selectively associated with contingency detection but not discrimination in rabbit discrimination-reversal eyeblink con…
2009
The relative power of the hippocampal theta-band ( approximately 6 Hz) activity (theta ratio) is thought to reflect a distinct neural state and has been shown to affect learning rate in classical eyeblink conditioning in rabbits. We sought to determine if the theta ratio is mostly related to the detection of the contingency between the stimuli used in conditioning or also to the learning of more complex inhibitory associations when a highly demanding delay discrimination-reversal eyeblink conditioning paradigm is used. A high hippocampal theta ratio was not only associated with a fast increase in conditioned responding in general but also correlated with slow emergence of discriminative res…
Multiple-unit responses to pitch changes in rabbits
1996
Multiple-unit activity (MUA) was recorded from the hippocampus (Hc), the visual cortex (VCx) and the cerebellar cortex (CerCx) in rabbits when pitch deviant tones were presented in a series of standard tones (oddball situation) and when standard tones were absent (deviant-alone situation). Significant MMN-like responses (deviant responses minus standard responses in the oddball situation) occurred in Hc, reflecting a MUA increase to the standards and its decrease to the deviants. In accordance with parallel ERPs reported earlier, the MMN-like responses reflected responses only to different presentation frequencies of stimuli. Non-selectivity in the pitch of such responses in VCx and a lack …
