Reservoir computing model of prefrontal cortex creates novel combinations of previous navigation sequences from hippocampal place-cell replay with sp…
2019
As rats learn to search for multiple sources of food or water in a complex environment, they generate increasingly efficient trajectories between reward sites. Such spatial navigation capacity involves the replay of hippocampal place-cells during awake states, generating small sequences of spatially related place-cell activity that we call “snippets”. These snippets occur primarily during sharp-wave-ripples (SWRs). Here we focus on the role of such replay events, as the animal is learning a traveling salesperson task (TSP) across multiple trials. We hypothesize that snippet replay generates synthetic data that can substantially expand and restructure the experience available and make learni…
Education connection regarding the cycle in social integration. Proposals for flexible curriculum in uncertainty times
2014
La crisis económica que vivimos ha incentivado la participación en la escena colectiva. Ello genera una serie de implicaciones estratégicas para la transformación socioeducativa desde el grupo clase, a partir de metodologías exploratorias como la investigación acción. Este trabajo presenta además, las principales percepciones de los estudiantes del Ciclo Formativo de Grado Superior en Integración Social con la intención de describir un perfil. Incentivamos esta metodología apoyados en las propuestas que Tarín y Navarro (2006) identifican respecto la relación educativa, al señalar que la efectividad de los contenidos curriculares quedan vinculados a las conexiones afectivas que logre activar…
Observing – Treating – Classifying: On the Educational Practice of Human Differentiation
2016
Abstract Sociological research often states the reproductive function of educational systems. Thus, students are differentiated according to their cultural capital and their social background. One central dimension of the selection process is the grading performed by teachers. The paper outlines a conceptional framework of dealing with this kind of human differentiation sociologically. It therefore gives insight into the prerequisites provided by the school administration and into the empirical organization of grading – from classroom assessment to teacher meetings where final decisions are taken. Two forms of objectifying students’ performances are presented: a social as well as a numerica…
Apathy Towards the Integration of Usability Work: A Case of System Justification
2016
In this article we report from a case study of a software development organization and we study in particular the developers’ and product managers’ attitudes towards integrating usability work into software development. We offer explanations based on system justification theory illuminating what would-be integrators might be up against. The analysis shows how the developers only pay lip service to usability work and how they treat users superficially. It further shows how that leads to stereotyping of usability designers and users in order to preserve status quo, and how internalization of inequality between the developers and usability designers rationalizes the preservation of status quo.…
Modeling joint and marginal distributions in the analysis of categorical panel data
2001
This article presents a unifying approach to the analysis of repeated univariate categorical (ordered) responses based on the application of the generalized log-linear modeling framework proposed by Lang and Agresti. It is shown that three important research questions in longitudinal studies can be addressed simultaneously. These questions are the following: What is the overall dependence structure of the repeated responses? What is the structure of the change between consecutive time points? and What is the structure of the change in the marginal distributions? Each of these questions involves specifying log-linear models for different marginal distributions of the multiway cross classifi…
Interindividual Differences in Treatment Effects based on Structural Equation Models with Latent Variables: An EffectLiteR Tutorial
2019
The investigation of interindividual differences in the effects of a treatment is challenging, because many constructs-of-interest in psychological research such as depression or anxiety are latent variables and modeling heterogeneity in treatment effects requires interactions and potentially nonlinear relationships. In this paper, we present a tutorial of the EffectLiteR approach (Mayer, Dietzfelbinger, Rosseel, & Steyer, 2016) that allows for estimating individual treatment effects based on latent variable models. We describe step by step how to apply the approach using the EffectLiteR software package with data from the multicenter randomized controlled trial of the Social Phobia…
Child-researcher relationships in child protection research : an integrative review
2021
In research with children, particularly those in contact with social and health services, researchers face ethical challenges and have stringent ethical obligations. One obligation regards the need for researchers to adopt a reflexive approach to considering how children’s perspectives and experiences are represented. In this paper, the nature of child-researcher relationships and researchers’ positions are examined to further understanding of how to account for the impact of contexts on meaning making in research with children. An integrative literature review of articles concerned with child protection identified a paucity of researcher accounts of reflexivity. The review articles contain…
Validation study of an evaluation scale of ‘perceived social justice’ in the primary and secondary education
2018
La evaluación educativa se ha basado fundamentalmente en el éxito académico. Sin embargo, estudios recientes han valorado estudiar la percepción que el propio alumnado tiene sobre otros aspectos como, por ejemplo, el de la justicia social. Así pues, el objetivo general de nuestro trabajo es el diseño de un instrumento que permita evaluar la percepción que crea el alumnado sobre justicia social educativa (JSP-E) a partir de las interacciones y relaciones que se establecen entre alumnado y profesorado. El constructo “Justicia Social Percibida en la Educación" se incluye dentro de la dimensión de equidad del modelo de evaluación de instituciones y sistemas educativos definido en Jornet (2012) …
Impact of a physical education service-learning programme on ASD children: A mixed-methods approach
2021
Abstract Background. Children with Autism Spectrum Disorder (ASD) have few opportunities to engage in physical activity, which affects their already limited social and motor skills. Different Service-Learning (SL) proposals designed to meet this need have started to emerge, and research is required to better understand the services provided. Objective. Two objectives were established in this study: (1) to understand the impact of a physical education SL programme from the viewpoints of Physical Education Teacher Education (PETE) students and the families of the children with ASD involved; and (2) to analyse the programme’s effects on the motor domain of children with ASD (physical activity …
