À bas la sélection ! Misère de la critique
2019
International audience; La critique de la sélection à l'entrée de l'université repose sur une vision misérabiliste des étudiants de milieu populaire et ne remet pas en question les inégalités au sein du système d'éducation. Il existe sans doute mille bonnes raisons d'être hostile à Parcoursup et à la réforme du baccalauréat, comme il existe de solides raisons de protester contre les conditions de travail des professeurs, des enseignants-chercheurs et des étudiants… Le propos de ce texte n'est pas de participer aux débats sur le bien-fondé des réformes ; il n'est ni de les défendre ni de les contester, mais d'interroger les cadres de la critique de la sélection que ces réformes sont censées …
The effect of inbreeding rate on fitness, inbreeding depression and heterosis over a range of inbreeding coefficients
2014
Understanding the effects of inbreeding and genetic drift within populations and hybridization between genetically differentiated populations is important for many basic and applied questions in ecology and evolutionary biology. The magnitudes and even the directions of these effects can be influenced by various factors, especially by the current and historical population size (i.e. inbreeding rate). Using Drosophila littoralis as a model species, we studied the effect of inbreeding rate over a range of inbreeding levels on (i) mean fitness of a population (relative to that of an outbred control population), (ii) within‐population inbreeding depression (reduction in fitness of offspring fro…

Hard to catch: Experimental evidence supports evasive mimicry
2021
Most research on aposematism has focused on chemically defended prey, but the signalling difficulty of capture remains poorly explored. Similar to classical Batesian and Müllerian mimicry related to distastefulness, such ‘evasive aposematism' may also lead to convergence in warning colours, known as evasive mimicry. A prime candidate group for evasive mimicry areAdelphabutterflies, which are agile insects and show remarkable colour pattern convergence. We tested the ability of naive blue tits to learn to avoid and generalizeAdelphawing patterns associated with the difficulty of capture and compared their response to that of birds that learned to associate the same wing patterns with distast…
La Investigación Acción Participativa (IAP) en el sector empresarial. Interviniendo desde lo local
2019
El artículo muestra el potencial de aplicación de las metodologías participativas de investigación y planeación social para una gestión participativa del conocimiento y el desarrollo de estrategias de intervención en el territorio. En este contexto se muestra una investigación realizada en base a metodologías de investigación acción-participación implementadas en una iniciativa empresarial de una localidad de la Comunidad Valenciana. Así, el carácter influyente y la capacidad de integrar saberes, conocimientos y aprendizajes de los diversos actores sociales e institucionales favorecen la promoción y el desarrollo de estrategias capaces de dar respuesta a las distintas problemáticas existent…
Exploring early adolescents’ stressful IT use experiences
2022
Early adolescents are accustomed to using information technology (IT) for different purposes as a part of their everyday life. While IT use can provide many benefits, it can also include negative experiences, such as feelings of stress (i.e. technostress). Considering that young IT users’ technostress perspectives have remained limited in the literature, this paper attempts to contrast their experiences with aspects from earlier research. A qualitative content analysis of semi-structured interviews with 31 primary and secondary school students reveals that early adolescents have encountered stressful IT use experiences that vary based on the degree of stress. The experiences relate to diffe…
Valoración y confianza de los espectadores de los programas de salud de TVE
2019
Televisión Española (TVE) has made possible the dissemination of medical topics in the 2016 season through four specialized health programs: Saber vivir, Centro médico, Esto es vida and El ojo clínico. In order to better understand their reception by spectators, this study analyzes, on the one hand, the data from the audiometry and, on the other hand, the results of a survey launched through social networks. The questionnaire, responded by 158 followers of the programs, measured the value of the programs and the spectators’ confidence in their informative and audiovisual treatment. This research corresponds to the second phase of a broader project in which the contents of television program…
Three-port colectomy: reduced port laparoscopy for general surgeons. A single center experience
2016
To evaluate three-port colectomy as an alternative reduced-port laparoscopy technique in colonic surgery.Retrospective study carried out through the analysis of 32 consecutive patients that underwent alternatively to a three ports left colectomy or a conventional laparoscopic colectomy for colonic diseases in order to evaluate the benefits of the reduced-port technique. A multivariate analysis among duration of surgery, hospital stay and conversion rate was performed using the OLS regression and the binary logistic regression.We found a reduced operative time in the three-port colectomy in comparison to the four-port technique (p=0.07). The hospital stay was not found related to the number …
DIALECTIC AND SOCIAL HETEROGENEITY IN ERNESTO LACLAU
2020
The present article aims to examine critically Laclau’s claim that the trend toward social heterogenization revokes the Dialectic, or, more specifically, the clear and strict line of demarcation between what falls within the Dialectic and what falls outside of it. Polemicizing with the assumption of this reading, I argue that the appearance of a radical heterogeneity rather exposes the undecidability of relations between the Dialectic and what is a heterogeneity. To undergo the experience of this relation means not only to confront something that dislocates the Dialectic, but also what makes it what it is. The concrete determination of this limit relation is precisely what is at stake in th…
Antitumor Effect of Cabozantinib in Bone Metastatic Models of Renal Cell Carcinoma
2021
Background: The presence of bone metastases in renal cell carcinoma (RCC) negatively affects patients’ survival. Data from clinical trials has highlighted a significant benefit of cabozantinib in bone metastatic RCC patients. Here, we evaluated the antitumor effect of cabozantinib in coculture models of renal cell carcinoma (RCC) and osteoblasts (OBs) to investigate whether and how its antiproliferative activity is influenced by OBs. Methods: Bone/RCC models were generated, coculturing green fluorescent protein (GFP)-tagged Caki-1 and 786-O cells with human primary OBs in a “cell–cell contact” system. RCC proliferation and the OB molecular profile were evaluated after the cabozantinib treat…
