Patterns and universals of mate poaching across 53 nations : the effects of sex, culture, and personality on romantically attracting another person’s partner

As part of the International Sexuality Description Project, 16,954 participants from 53 nations were administered an anonymous survey about experiences with romantic attraction. Mate poaching--romantically attracting someone who is already in a relationship--was most common in Southern Europe, South America, Western Europe, and Eastern Europe and was relatively infrequent in Africa, South/Southeast Asia, and East Asia. Evolutionary and social-role hypotheses received empirical support. Men were more likely than women to report having made and succumbed to short-term poaching across all regions, but differences between men and women were often smaller in more gender-egalitarian regions. People who try to steal another's mate possess similar personality traits across all regions, as do those who frequently receive and succumb to the poaching attempts by others. The authors conclude that human mate-poaching experiences are universally linked to sex, culture, and the robust influence of personal dispositions.peer-reviewe

Are men universally more dismissing than women? Gender differences in romantic attachment across 62 cultural regions

The authors thank Susan Sprecher (USA), Del Paulhus (Canada), Glenn D. Wilson (England), Qazi Rahman (England), Alois Angleitner (Germany), Angelika Hofhansl (Austria), Tamio Imagawa (Japan), Minoru Wada (Japan), Junichi Taniguchi (Japan), and Yuji Kanemasa (Japan) for helping with data collection and contributing significantly to the samples used in this study.Gender differences in the dismissing form of adult romantic attachment were investigated as part of the International Sexuality Description Project—a survey study of 17,804 people from 62 cultural regions. Contrary to research findings previously reported in Western cultures, we found that men were not significantly more dismissing than women across all cultural regions. Gender differences in dismissing romantic attachment were evident in most cultures, but were typically only small to moderate in magnitude. Looking across cultures, the degree of gender differentiation in dismissing romantic attachment was predictably associated with sociocultural indicators. Generally, these associations supported evolutionary theories of romantic attachment, with smaller gender differences evident in cultures with high–stress and high–fertility reproductive environments. Social role theories of human sexuality received less support in that more progressive sex–role ideologies and national gender equity indexes were not cross–culturally linked as expected to smaller gender differences in dismissing romantic attachment.peer-reviewe

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Retour de vécu et d’expérience de la prise en charge médico-psychologique des personnels de l’hôpital psychiatrique de Pau dans les suites immédiates du double meurtre de nos collègues

Dans la nuit du 17 au 18 décembre 2004 au Centre Hospitalier des Pyrénées à Pau, Chantal Klimaszewski et Lucette Gariod, deux soignantes, deux d’entre nous, sont « sauvagement » tuées et trouvées au matin par l’équipe de relève. Travaillant dans cet établissement et donc collègue de ces soignantes, mais étant également membre de la Cellule d’Urgence Médico-Psychologique (C.U.M.P.) nous avons été appelés, dès la première heure, à intervenir. Il s’agissait, conformément aux missions des C.U.M.P., d’apporter une aide, par la prise en charge psychologique, aux collègues, aux proches et aux intervenants en souffrance, alors que nous étions nous-mêmes des « impliqués » dans le même choc émotionnel. De plus, le présumé meurtrier (ce qui se confirmera quelques semaines plus tard) se trouve être un patient de l’établissement.Après quelques informations sur l’origine et la nature des missions des C.U.M.P., nous tenterons un récit de notre action de par l’un des membres de la cellule. Ce récit peut être lui-même à l’image de ce dont il parle, à savoir un débriefing. Et c’est même un débriefing comme dans la pratique, avec ses limites par rapport à la théorie, car dans le récit qui ne se voudrait être exposé que comme des faits, finissent par transparaître les sentiments et le vécu émotionnel personnel.Nous n’avons probablement toujours pas suffisamment de recul sur le vécu de ce drame ni même, simplement, sur notre action pratique immédiate et post-immédiate, pour en proposer une analyse très en profondeur. Nous proposerons donc simplement quelques questionnements et notre point de vue, en particulier sur la pertinence d’intervenir et la façon dont nous avons répondu dans l’urgence à une demande d’aide.During the night from 18th to 19th of December 2004, at the Pyreneans Hospital Centre at PAU (France), Chantal Klimaszewski et Lucette Gariod, a nurse and her auxiliary, two of us, have been killed wildly and found by morning team. CUMP’s members (Medico-Psychological Urgency Cell) but also colleagues of the two victims, we were called at the very beginning to intervene. The question was, in accordance with of the CUMP’s missions, to help our fellow workers, families, and all participants with a psychological care, and we were also shocked by the tragedy. Over and above this the killer was a hospital patient (that’s what the investigation had discovered)We’ll try a narrative of our action by one of the department’s members after some information’s about CUMPS’s origin’s and mission’s nature. This narrative is a debriefing; a real debriefing; limited in the theory because feelings and emotional experiences are showing though facts.Probably we are not objective enough about this experience, neither about our instantaneous action to propose you a deeply analysis. So we propose you some interrogations and our point of view, about the pertinence to intervene and the way that we answered at the request urgency action

Interpenetrated Si-HPMC/alginate hydrogels as a potential scaffold for human tissue regeneration

International audienceInterpenetrated gels of biocompatible polysaccharides alginate and silanized hydroxypropyl methyl cellulose (Si-HPMC) have been studied in order to assess their potential as scaffolds for the regeneration of human tissues. Si-HPMC networks were formed by reduction of the pH to neutral and alginate networks were formed by progressive in situ release of Ca+. Linear and non-linear mechanical properties of the mixed gels at different polymer and calcium concentrations were compared with those of the corresponding single gels. The alginate/Si-HPMC gels were found to be stiffer than pure Si-HPMC gels, but weaker and more deformable than pure alginate gels. No significant difference was found for the maximum stress at rupture measured during compression for all these gels. The degrees of swelling or contraction in excess water at pH 7 as well as the release of Ca2+ was measured as a function of time. Pure alginate gels contracted by as much as 50 % and showed syneresis, which was much reduced or even eliminated for mixed gels. The important release of Ca2+ upon ageing for pure alginate gels was much reduced for the mixed gels. Furthermore, results of cytocompatibility assays indicated that there was no cytotoxicity of Si- HPMC/alginate hydrogels in 2D and 3D culture of human SW1353 cells. The results show that using interpenetrated Si-HPMC/alginate gels has clear advantages over the use of single gels for application in tissue regeneration
