Habitat assessment by parasitoids: consequences for population distribution

2006

International audience; The ideal free distribution (IFD) is a stable distribution of competitors among resource patches. For equally efficient competitors, equilibrium is reached when the per capita rate of intake equalizes across patches. The seminal version of the IFD assumes omniscience, but populations may still converge toward the equilibrium provided that competitors 1) accurately assess their environment by learning and 2) remain for an optimal (rate-maximizing) time on each encountered patch. In the companion article (Tentelier C, Desouhant E, Fauvergue X. 2006. Habitat assessment by parasitoids: mechanisms for patch time allocation. Behav Ecol. Forthcoming), it is shown that the p…

The Breast Size Satisfaction Survey (BSSS): Breast size dissatisfaction and its antecedents and outcomes in women from 40 nations

2020

The Breast Size Satisfaction Survey (BSSS) was established to assess women's breast size dissatisfaction and breasted experiences from a cross-national perspective. A total of 18,541 women were recruited from 61 research sites across 40 nations and completed measures of current-ideal breast size discrepancy, as well as measures of theorised antecedents (personality, Western and local media exposure, and proxies of socioeconomic status) and outcomes (weight and appearance dissatisfaction, breast awareness, and psychological well-being). in the total dataset, 47.5 % of women wanted larger breasts than they currently had, 23.2 % wanted smaller breasts, and 29.3 % were satisfied with their curr…

A numerical property of Hilbert functions and lex segment ideals

2017

We introduce the fractal expansions, sequences of integers associated to a number. We show that these sequences characterize the Osequences and encode some information about lex segment ideals. Moreover, we introduce numerical functions called fractal functions, and we use them to solve the open problem of the classification of the Hilbert functions of any bigraded algebra.

Getting married or entering into a partnership : the patrimonial issues of choice in french law

2021

In French law, there are only two models of couples between which a choice is really possible to organize their patrimonial relationships: partnership or marriage. But, if the couple intends to organize a transfer of assets between companions both during the union and in case of death, it is definitely marriage that offers more possibilities than partnership. Often, young French couples, who do not wish to marry, either not at the begining of their relationship or not at all, have the idea that, if marriage organizes a legal protection of the couple, the partners have the possibility to provide conventionally equivalent protection. In fact, this idea is wrong.

Tratamiento didáctico en la enseñanza de las ciencias, de los errores conceptuales

1987

Los errores conceptuales (principalmente en Física y Química), constituyen un grave problema, no solo por su extensión (afectan a un gran número de estudiantes de todos los países y de cualquier nivel educativo) sino también porque frecuentemente responden a ideas alternativas sobre conceptos científicos básicos, las cuales resultan muy difíciles de cambiar, incluso aun cuando son tenidas explícitamente en cuenta en la enseñanza. Todo ello contribuyó sin duda a que en la década de los 80 se realizase una investigación muy abundante en torno al tema de las concepciones alternativas de los alumnos, de la cual forma parte esta tesis doctoral (primera sobre errores conceptuales en física y quím…

INTELLECTUAL FILTERS AND THE DISSEMINATION OF SMITHIANISM AN INTRODUCTORY NOTE

2020

Adfam Smith’s thought reached every corner of the world in a short lapse of time but made its entrance through institutional, cultural, linguistic, religious and political filters. These filters are not neutral and affected the reading, understanding and use of Smithian ideas. I chose the keyword ‘intellectual filters’ to denote all of the contextual elements whose influence determines whether and how a foreign paradigm penetrates a country and creates its effects.

Disentangling relations between the desirability of the thin-ideal, body checking, and worry on college women's weight-loss dieting

2019

The study used self-regulation theory to elucidate the relationships between the desirability of the thin-ideal goal, dispositional worry, body checking and weight-loss dieting (WLD) in college women. We hypothesized that body checking would mediate the relationship between the desirability of the thin-ideal goal and WLD: the desire to be thin would be associated with more WLD through more frequent body checking. We also hypothesized that dispositional worry would moderate this mediation pathway, such that the mediation pathway would be stronger for those higher in worry. Finally, all effects were expected to occur when controlling for self-reported body size. A paper and pencil survey was …

Childhood abuse experiences, depression and dissociation symptoms in relation to suicide attempts and suicidal ideation

2021

This study aimed to examine associations between suicide attempts (SA), suicidal ideation (SI), depression, dissociative symptoms, emotional abuse, physical abuse and sexual abuse, and to explore predictors of SA and SI, as well as possible mediating factors. We also aimed to examine support for a dissociative depression subgroup. Participating in this study were 342 adults, of these were 138 respondents with a diagnosis of depression (DG), and 204 respondents comprising a community sample (CS). Respondents completed the Center for Epidemiologic Studies Depression Scale - Revised (CESD-R), Childhood Trauma Questionnaire - Short Form (CTQ-SF), and Dissociative Experience Scale (DES). All but…

Modern health worries and idiopathic environmental intolerance attributed to electromagnetic fields are associated with paranoid ideation.

2021

Paranoid ideation is assumed to characterize worries about possible harmful effects of modern technologies (MHWs) and idiopathic environmental intolerances (IEIs), such as IEI attributed to electromagnetic fields (IEI-EMF). Empirical evidence on these associations is scarce.In a cross-sectional on-line survey, participants of a community sample (n = 700; mean age: 28.4 ± 12.0; 434 females) completed the Somatosensory Amplification Scale, the Modern Health Worries Scale, and the Paranoid Ideation scale of the Symptom Checklist 90 Revised. They were considered IEI-EMF if (1) they categorized themselves so, (2) they had experienced symptoms that they attributed to the exposure to electromagnet…
