    Póster 14.º Encontro da Associação Portuguesa de Psicologia Experimental. Universidade de Évora (Portugal), 3-4 mayo 2019[EN]The productivity of future professionals is usually conditioned by their ability to work in groups. Therefore, the EHEA has promoted various forms of teaching methodologies that require group activities by the university student. However, the consequences of a voluntary or forced assignment of students to such activities are still not well known. In addition to the type of assignment to the group, various variables intervene conditioning the proper functioning and didactic effectiveness of these activities. These variables can be of individual or collective type. The variables of individual type used in this study are: peer attachment, characterized by the person's way of bonding (Bowlby, 1969; Leiter, Day and Price, 2015); the expectation of self-efficacy, considered as confidence in one's ability to achieve the intended results (Ormrod, 2006); and the attitude toward collaborative learning, understood as the attitude towards working in small groups based on participation and positive interdependence. The collective variables selected are the team roles that make up the different work groups (Belbin, 2015). Each student can play several roles depending on the needs of the team and, also, according to their own interests. A team role is the commitment that the individual acquires to perform a certain function, adjusting their skills to the needs of the team. OBJETIVE Analyze the relationships between attachment, self-efficacy, attitude toward collaborative learning and team role, as well as the effect of voluntary or random training of work groups on team roles.Funded in the Call for Aid for Innovation Projects and Teacher Improvement 2018/19 (USAL

    La sombra del patriarcado en las redes sociales del aula

    La sociedad actual se encuentra inmersa en profundos cambios relacionales ligados a la identidad de género, manifestándose de diferentes formas, entre las que se encuentra la violencia de género. En este sentido, y en el marco del proyecto de excelencia Teón XXI, en el que se está realizando el diagnóstico de género en el sistema escolar andaluz como primera medida para la prevención de conductas violentas, cobra importancia analizar las relaciones que los y las estudiantes establecen. Así, el análisis de las redes sociales del aula constituye el objetivo principal de este estudio. En este trabajo se desarrollan técnicas sociométricas para analizar las redes sociales del aula con perspectiva de género, los posicionamientos y el estatus del alumnado. La metodología experimental utilizada, complementada con encuesta y observación, permite valorar la incidencia de los mandatos del patriarcado en la sociología escolar en aulas de Educación Primaria y Secundaria de Sevilla. Los resultados muestran cómo los mandatos de género influyen en la elección y rechazo de estudiantes, asimismo se contrastan diferencias en las relaciones que establece el alumnado según el supuesto presentado, identificándose formas de liderazgo diferentes en función del género

    Multichannel Retailing and Consumer Behaviour: Strategy Design and Implementation

    Get PDF
    This article aims to analyse and offer managerial guidance about the processes of planning, implementation and control of a multichannel strategy within the framework of Multichannel Customer Management Decision (MCMD). To achieve this objective, firstly we justify the growing adoption of a multichannel strategy by retailers and channels participants. Following MCMD framework, we analyse the consumer behaviours linked to this kind of strategy in order to deeply understand the factors which affect consumer choice decisions related to channels. Alternative channels to brick and mortar retail channel are described, such as online channel. This helps us to offer a guide to define the multichannel strategy. Additionally, we give some ideas about the implementation of this strategy. Finally, in order to get a feedback to this planning process, we suggest carrying out a control phase. The work ends with conclusions section and future research streams

    On modeling and nano-analysis of caries-affected dentin surfaces restored with Zn-containing amalgam and in vitro oral function

    The aim of this research was to assess the influence of mechanical loading on the ability of Zn-free vs Zn-containing amalgams to promote remineralization at the dentin interface. Sound (SD) and caries-affected dentin surfaces (CAD) were restored using Zn-free or Zn-containing dental amalgams. Mid-coronal dentin surfaces were studied by 1) Atomic Force Microscopy (AFM) analysis (including plot and phase imaging, nanoindentation test (modulus of Young (Ei), nano-roughness measurements, and fibril diameter assessment), 2) Raman spectroscopy/cluster analysis, 3) X-ray diffraction (μXRD2), 4) field emission electron microscope (FESEM) and energy-dispersive analysis (EDX), for morphological, mechanical, and physico-chemical characterization. Analyses were performed before amalgam placement and after amalgam removal, at 24 hours and 3 weeks of load cycling. Zn-free and Zn-containing amalgams restorations promoted an increase in the modulus of Young of CAD surfaces, after three weeks of load cycling; at this time, Zn-containing amalgams attained higher Ei than Zn-free restorations. Zn-containing amalgams induced tubular occlusion after load cycling, in both sound and CAD. Zn free-amalgams promoted remineralization of both intertubular and peritubular dentin in CAD substrata. These minerals were identified as calciumphosphate deposits, and crystals as hydroxyl-apatite with augmented crystallographic maturity but with some components of lattice distortion. Crosslinking of collagen diminished and secondary structure of collagen increased in CAD substrate restored with Zn-containing amalgam after 3 w of load cycling, indicating an advanced preservation, molecular organization and orientation of collagen fibrils after load cycling. Plot and phase images permitted to observe the topographical changes which were promoted by the mineral deposits; in general, the indexes related to higher remineralization gave rise to a decrease of nano-roughness and an augmentation of the bandwidth of the collagen fibrils. Zn-containing amalgam restorations submitted to mechanical stimuli promote remineralization of the partially mineral-depleted subjacent substrate at the caries-affected dentin.This work was supported by Grant Nos.
