The role of depression and impulsivity in the psychopathology of bulimia nervosa.
2013
Introduction: The study aimed to analyze the role of depression and impulsivity in the psychopathology of bulimia nervosa (BN). Materials and methods: Seventy female patients with DSM-IV BN, purging subtype, were assessed for eating-related symptoms, body dissatisfaction, affective symptoms, impulsivity, and personality traits. Factor analysis and structural equation modeling methods were used for statistical analysis. Results: BN appeared as a condition which incorporated 5 general dimensions: a) binge eating and compensatory behaviours; b) restrictive eating; c) body dissatisfaction; d) dissocial personality traits; and e) a cluster of features which was called "emotional instability" The…
Digital Inequalities: A Review of Contributing Factors and Measures for Crossing the Divide
2019
Part 8: Digital Divide and Social Inclusion; International audience; This literature review focuses on the digital divide in contemporary technologically and economically advanced societies. Prior research shows that the digital divide entails more than physical accessibility and points to issues of technology acceptance and actual use. Recurring digital divide factors outside socioeconomic characteristics were identified in the articles reviewed. These factors relate to personality traits, motivation and digital skills. The factors can be used as the basis for a personality model for understanding acceptance and use of technology complementing models related to economic and social resource…
Costs and benefits of inflammation in host-parasite relationships
2016
Host-parasite interactions are characterized by trade-offs that involve both plastic and microevolutionary responses. On one hand, while immunity is essential to fight parasites, it can also cause damage to the host, leading to autoimmunity and inflammatory diseases. On the other hand, parasites have to cope with the immune environnement provided by the host. This raises the question of the costs and benefits of the inflammatory response for the two partners of the interaction. With different experimental and literature-based approaches, I showed that immunopathology is a trait that likely persists because of the immediate benefits of the immune response in terms of protection against paras…
Effets d’extraits de raquette du cactus -Opuntia ficus indica- sur la modulation du stress oxydant et du processus inflammatoire liés à la déficienc…
2018
Acyl-CoA oxidase 1 (ACOX1) deficiency is a rare and severe peroxisomal leukodystrophy associated with a very long-chain fatty acids β-oxidation defect. As peroxisomal defects in microglia appear to be a key component of physiopathogenesis in ACOX1 deficiency, we used the murine BV-2 microglial cell line as model: (i) to evaluate the antioxidant and anti-inflammatory properties of Opuntia ficus-indica cactus cladode extracts; (ii) to characterize a new BV-2 ACOX1 deficient cell line recently generated in our laboratory by CRISPR/Cas9 gene editing. In the first part of this work, the microglia activation, achieved by BV-2 cells exposition to four structurally and biologically well-defined lip…
Child behaviour and adult personality: comparisons between criminality groups in Finland and Sweden
2000
Background; Lately there has been an increasing interest in whether personality traits are associated with criminal behaviour in male and female subjects. Criminality and alcohol abuse are often associated. Delinquent adolescents are impulsive and danger seeking. Childhood aggression may be a precursor of adult criminality. Method Using longitudinal data, adult personality and childhood behaviours were examined for groups of non-criminals and criminals of Finnish (n = 268) and Swedish (n + 169) samples, and crime groups were compared in the two cultures. Karolinska Scales of Personality (KSP) were given at adult age and the participants had been observed and rated by their teachers in respe…
Costuming in Seán Keating’s self-portraits: theatrical guise or political disguise?
2018
L’œuvre du peintre irlandais Seán Keating (1889–1977) a accompagné l’affirmation d’une irlandité mêlant tradition et modernité. Dans cette perspective, les nombreux autoportraits de l’artiste peuvent être considérés comme un moyen d’incarner un idéal politique. Le recours au costume dans ses autoportraits mérite attention. En effet, Keating reprend une tradition picturale bien établie en se représentant de manière ludique en costume mais utilise le dispositif de manière plus politique. En revêtant le costume traditionnel des habitants des îles d’Aran ou bien en se portraiturant en habit traditionnel dans des compositions aux accents nationalistes, Keating incarne des idées politiques et aff…
The case for strategic international alliances to harness nutritional genomics for public and personal health
2005
Nutrigenomics is the study of how constituents of the diet interact with genes, and their products, to alter phenotype and, conversely, how genes and their products metabolise these constituents into nutrients, antinutrients, and bioactive compounds. Results from molecular and genetic epidemiological studies indicate that dietary unbalance can alter gene-nutrient interactions in ways that increase the risk of developing chronic disease. The interplay of human genetic variation and environmental factors will make identifying causative genes and nutrients a formidable, but not intractable, challenge. We provide specific recommendations for how to best meet this challenge and discuss the need …
MoodlePeers: Factors Relevant in Learning Group Formation for Improved Learning Outcomes, Satisfaction and Commitment in E-Learning Scenarios Using G…
2016
High-scale and pure online learning scenarios (like MOOCs) as well as blended-learning scenarios offer great possibilities to optimize the composition of learning groups working together on the assigned (or selected) tasks. While the benefits and importance of peer learning for deep learning and improvement of e.g. problem-solving competency and social skills are indisputable, little evidences exist about the relevant factors for group formation and their combination to optimize the learning outcome for all participants (in all groups). Based on the GroupAL algorithm, MoodlePeers proposes an plugin solution for Moodle. Evaluated in a four-week online university mathematics preparation cours…
Bryophytes of Europe Traits (BET) dataset
2023
The Bryophytes of Europe Traits (BET) dataset includes values for 65 biological and ecological traits and 25 bioclimatic variables for all 1816 bryophytes included in the European Red List (Hodgetts et al. 2019). The traits are compiled from several regional trait datasets and manually complemented using Floras, species-specific literature and expert knowledge. The bioclimatic variables are calculated using the European range of each species. Details regarding the trait compilation and extraction of bioclimatic variables can be found in the corresponding data paper (Van Zuijlen et al. 2023).
Laboratory relationships between adult lifetime reproductive success and fitness surrogates in a Drosophila littoralis population
2011
The difficulties in measuring total fitness of individuals necessitate the use of fitness surrogates in ecological and evolutionary studies. These surrogates can be different components of fitness (e.g. survival or fecundity), or proxies more uncertainly related to fitness (e.g. body size or growth rate). Ideally, fitness would be measured over the lifetime of individuals; however, more convenient short-time measures are often used. Adult lifetime reproductive success (adult LRS) is closely related to the total fitness of individuals, but it is difficult to measure and rarely included in fitness estimation in experimental studies. We explored phenotypic correlations between female adult LRS…
