El papel de la cultura del honor, del sexismo y de los celos en la respuesta a la infidelidad de la pareja
Canto Ortiz,Jesús María; Moreno Jiménez,Pilar; Perles Novas,Fabiola; San Martín García,Jesús;
Escritos de Psicología (Internet) , 2012,
Abstract: the aim of this study was to investigate whether a culture of honour, sexism and jealousy influenced the type of infidelity (sexual or emotional) experienced by the participants. a total of 170 university students (80 men and 90 women) participated. they responded to six dilemmas indicating which type of infidelity most affected them (sexual or emotional) using a culture of honour scale, a sexism inventory and a jealousy scale. there were differences between men and women only in two dilemmas. the influence of a culture of honour, hostile sexism, benevolent sexism and jealousy on sexual and emotional infidelity was analyzed. women who scored high on a culture of honour, benevolent sexism and jealousy were those who felt most affected by sexual infidelity.

Escritos de Psicología (Internet) , 2011,
Abstract: the aim of this study was to analyse the relationship between emotional intelligence, jealousy and the propensity for abusiveness and violent conflict-solving strategies between couples. the predictive capacity of these variables was analysed in a mixed sample of 294 people. the outcomes show that the variables evaluated are significantly associated with the conflict-solving strategies used by the couple. these strategies have a positive association with jealousy and the propensity for abusiveness, and a negative association with emotional intelligence. similarly, all the variables analysed had a predictive capacity regarding the conflict-solving strategies, especially the couple's perception regarding such strategies. these outcomes show the relevance of these variables in predicting violence between couples and are suggestive of interventions for its prevention.

Técnicas para revelar el borde de grano austenítico en aceros microaleados
García de Andrés, Carlos,Bartolomé García, María Jesús,Capdevila Montes, Carlos,San Martín Fernández, David
Revista de Metalurgia , 2001,
Abstract: The prior austenite grain size (PAGS) exerts an important influence on the microstructures forged by continuous cooling in the steel and on their mechanical properties. Since microalloyed steels have received considerable attention in the last years and enormous difficulties have been repetitively to reveal the austenite grain boundaries in these steels, this work analyzes the different techniques effective in that sense, which enable thus an accurate determination of the PAGS. This paper presents results obtained applying different conventional techniques such us chemical etching of quenched microstructures, the application of thermal cycles that enable the formation of phases around the prior austenite grain boundaries or oxidation etching which reveals the austenite grain boundaries by the preferential accumulation of oxides. Finally, an innovative and effective technique to reveal the prior austenite grain boundaries is presented. This technique is based on the preferential transfer of matter from the grain boundaries to the surrounding austenite by complicated mechanisms such as evaporation-condensation and volume and surface diffusion of atoms. El tama o de grano austenítico (TGA) tiene una gran influencia sobre la microestructura final y sobre las propiedades mecánicas de los productos obtenidos por transformación anisotérmica del acero. Debido a la considerable atención que se está prestando a los aceros microaleados en los últimos a os y a las dificultades que se encuentran en muchos casos para poder revelar los bordes de grano austenítico de estos aceros, en este trabajo se han analizado las técnicas que lo hacen posible, permitiendo así la determinación fiable del TGA. En este sentido, se presentan los resultados obtenidos al aplicar aislada y combinadamente distintas técnicas tradicionales, como el ataque químico de microestructuras obtenidas directamente por temple, la aplicación de diferentes tipos de ciclos térmicos en los que se mantienen constantes las condiciones de austenización que predeterminan el TGA y el ataque por oxidación, el cual produce oxidaciones preferentes en los bordes de grano. Finalmente se presenta también una de las técnicas más innovadoras y eficaces para revelar el grano austenítico que es conocida como ataque térmico. Esta técnica tiene su fundamento en los fenómenos de transferencia de materia producidos desde los bordes de grano por complicados mecanismos, aún no perfectamente identificados, tales como la evaporación-condensación y la difusión superficial y en volumen de átomos.

Abstract: the principal aim of this study tries to analyze the job satisfaction into low-skilled jobs realized by immigrants, looking for differences between women and men. is analyzed a sample of 250 immigrants who live in spain proceeding from different cultures. the variables evaluated across written questionnaire are: job satisfaction, burnout and some job characteristics. no differences were found between men and women in burnout or job satisfaction. so much cynicism as the depletion negatively correlated with job satisfaction. the results of the regression analysis showed predictive models differ according to sex: in men, the professional effectiveness and cynicism are more important than women; in women the exhaustion is negatively predicted job satisfaction. in addition, satisfaction with free time and job security predicts job satisfaction in both groups of immigrants.
Treball per projectes amb servei a la comunitat Working for projects with services to the community Trabajo por proyectos con servicio a la comunidad
Ma. Jesús Martín García
Temps d'Educació , 2011,
Abstract: Aquest article té com a objectiu contribuir a recuperar un element constitutiu del treball per projectes, però que sovint ha estat ignorat en la pràctica escolar: el servei a la comunitat. Per fer-ho, es recuperen les aportacions d'autors de finals del segle XIX i primera meitat del segle XX que, des de diferents perspectives, reivindiquen la projecció social i l'acció en el medi com a trets bàsics de la recerca cooperativa. Es presenta la proposta metodològica del treball per projectes hereva de Dewey i de Kilpatrick, i s’incorporen les modificacions que l'acció de servei suposa en l’àmbit didàctic i els beneficis que genera des del punt de vista formatiu. Finalment es descriuen dues experiències de treball per projectes amb servei a la comunitat. Al llarg de l'article es defensa que qualsevol recerca augmenta el seu potencial educatiu si té una voluntat transformadora, si es fa amb la intenció de millorar l'entorn. ______________________________________________ Cet article a pour objectif de contribuer à récupérer un élément constitutif du travail par projets qui a souvent été ignoré dans la pratique scolaire : le service à la communauté. Pour ce faire, il reprend les contributions d’auteurs de la fin du XIXe siècle et de la première moitié du XXe qui revendiquent, dans différentes perspectives, la projection sociale et l’action dans le milieu comme caractéristiques de base de la recherche coopérative. L’article présente la proposition méthodologique du travail par projets héritière de Dewey et de Kilpatrick et incorpore les modifications que l’action de service suppose dans le domaine didactique ainsi que les bénéfices qu’elle génère du point de vue de la formation. Enfin, il décrit deux expériences de travail par projets offrant un service à la communauté. Au fil de l’article, celui-ci défend que toute recherche augmente son potentiel éducatif s’il y a une volonté de transformation, si elle est faite avec l’intention d’améliorer l’environnement. The objective of this article is to recuperate a component of project work which is all too often forgotten in school work: service to the community. To do so, it looks back at the contributions of authors from the latter half of the 19th century and the first half of the 20th century from different perspectives, and champions the social dimension and action in the community as basic features of cooperative research. It presents a working method for projects that is based on the ideas of Dewey and Kilpatrick and incorporates the modifications in the educational field that service implies, and the benefits it
Convergence Time towards Periodic Orbits in Discrete Dynamical Systems
Jesús San Martín, Mason A. Porter
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0092652
Abstract: We investigate the convergence towards periodic orbits in discrete dynamical systems. We examine the probability that a randomly chosen point converges to a particular neighborhood of a periodic orbit in a fixed number of iterations, and we use linearized equations to examine the evolution near that neighborhood. The underlying idea is that points of stable periodic orbit are associated with intervals. We state and prove a theorem that details what regions of phase space are mapped into these intervals (once they are known) and how many iterations are required to get there. We also construct algorithms that allow our theoretical results to be implemented successfully in practice.
Synthesis and Structural Characterization of Hydroxyapatite-Wollastonite Biocomposites, Produced by an Alternative Sol-Gel Route  [PDF]
Martín A. Encinas-Romero, Jesús Peralta-Haley, Jesús L. Valenzuela-García, Felipe F. Castillón-Barraza
Journal of Biomaterials and Nanobiotechnology (JBNB) , 2013, DOI: 10.4236/jbnb.2013.44041
Abstract:

Hydroxyapatite is a type of calcium phosphate-based material with great interest for biomedical applications, due to the chemical similarity between this material and the mineral part of human bone. However, synthetic hydroxyapatite is essentially brittle; the practice indicates that the use of hydroxyapatite without additives for implant production is not efficient, due to its low strength parameters. In the present work, biocomposites of hydroxyapatite-wollastonite were synthesized by an alternative sol-gel route, using calcium nitrate and ammonium phosphate as precursors of hydroxyapatite, and high purity natural wollastonite was added in ratios of 20, 50 and 80 percent by weight immersed in aqueous medium. Formation of hydroxyapatite occurs at a relatively low temperature of about 350?C, while the wollastonite remains unreacted. After that, these biocomposites were sintered at 1200?C for 5 h to produce dense materials. The characterization techniques demonstrated the presence of hydroxyapatite and wollastonite as unique phases in all products.
