Performance and control of upright bipedal posture requires a constant and dynamic integration of relative contributions of different sensory inputs (i. e., sensory reweighting) to enable effective adaptations as individuals face environmental changes and perturbations. Children with gymnastic experience showed balance performance closer to that of adults during and after proprioceptive alteration than children without gymnastic experience when their center of pressure (COP) was analyzed. However, a particular COP sway can be achieved through performing and coordinating different postural movements. The (...) aim of this study was to assess how children and adults of different gymnastic experience perform and control postural movements while they have to adjust balance during and after bilateral tendon vibration. All participants were equipped with spherical markers attached to their skin and two vibrators strapped over the Achilles tendons. Bipedal stance was performed in three 45-s trials in two visual conditions (eyes open, EO, and eyes closed, EC) ordered randomly in which vibration lasted 10 s. Posture movements were analyzed by a principal component analysis (PCA) calculated on normalized and weighted markers coordinates. The relative standard deviation of each principal movement component (principal position, PP-rSTD) quantified its contribution to the whole postural movements, i.e., quantified the coordinative structure. The first (principal velocities, PV-rSTD) and second (principal accelerations, PA-rSTD) time-derivatives characterized the rate-dependent sensory information associated with and the neuromuscular control of the postural movements, respectively. Children without gymnastic experience showed a different postural coordinative structure and different sensory-motor control characteristics. They used less ankle movements in the anterior-posterior direction but increased ankle movements in medio-lateral direction, presented larger hip and trunk velocities, and exhibited more hip actions. Gymnastic experience during childhood seemed to benefit the development of proprioceptive reweighting processes in children, leading to a more mature form of coordinating and controlling posture similarly to adults.

Background The work of Research Ethics Boards (REBs), especially when involving genetics research and biobanks, has become more challenging with the growth of biotechnology and biomedical research. Some REBs have even rejected research projects where the use of a biobank with coded samples was an integral part of the study, the greatest fear being the lack of participant protection and uncontrolled use of biological samples or related genetic data. The risks of discrimination and stigmatization are a recurrent issue. In light (...) of the increasing interest in biomedical research and the resulting benefits to the health of participants, it is imperative that practical solutions be found to the problems associated with the management of biobanks: namely, protecting the integrity of the research participants, as well as guaranteeing the security and confidentiality of the participant's information. Methods We aimed to devise a practical and efficient model for the management of biobanks in biomedical research where a medical archivist plays the pivotal role as a data-protection officer. The model had to reduce the burden placed on REBs responsible for the evaluation of genetics projects and, at the same time, maximize the protection of research participants. Results The proposed model includes the following: 1) a means of protecting the information in biobanks, 2) offers ways to provide follow-up information requested about the participants, 3) protects the participant's confidentiality and 4) adequately deals with the ethical issues at stake in biobanking. Conclusion Until a governmental governance body is established in Quebec to guarantee the protection of research participants and establish harmonized guidelines for the management of biobanks in medical research, it is definitely up to REBs to find solutions that the present lack of guidelines poses. The model presented in this article offers a practical solution on a day-to-day basis for REBs, as well as researchers by promoting an archivist to a pivotal role in the process. It assures protection of all participants who altruistically donate their samples to generate and improve knowledge for better diagnosis and medical treatment. (shrink)

LA ÉTICA DE EDMUND HUSSERL trata de recoger la doctrina ética de Edmund Husserl (1859–1938), con la idea de dar a conocer el contenido moral que encierra la rica obra husserliana. Además, constituye una buena introducción a quienes se aproximan a la filosofía del fundador de la fenomenología, y un buen servicio incluso para quienes ya conocen su pensamiento solamente en relación con la teoría del conocimiento o con la lógica. Concretamente, la ética de Husserl —en un cuidado y ajustado (...) equilibrio entre el papel de la razón, el de la voluntad y el del sentimiento— ofrece la posibilidad de rescatar la afectividad del sentimentalismo ciego e instintivo sin caer en el extremo contrario del racionalismo inhumano; enseña cómo tomar libre y realmente nuestra vida en nuestras propias manos y dirigirnos a un ideal personal; muestra cómo comportarnos con nuestros semejantes reconociéndolos en su verdadera dignidad, y cómo podemos ayudarnos los unos a los otros. Y para todo ello, en fin, nos proporciona el suelo seguro de la experiencia interna evidente, resistente a toda crítica procedente de la ciencia empírica o del cinismo posmoderno. La exposición del discurso ético pasa necesariamente por meandros psicológicos y antropológicos, como no podía ser de otra manera. De modo que la doctrina moral de Husserl desvela asimismo e inseparablemente un sustancioso contenido psicológico y antropológico. Por otra parte, se ha preferido mantener en general el estilo fenomenológico del autor, esto es, procediendo analíticamente en sucesivos niveles de profundidad. (shrink)

Desde hace ya bastante tiempo existe una tendencia a afirmar que el derecho o las normas de diferente tipo no son adecuadas o aplicables para las diferentes nuevas tecnologías que van apareciendo de forma continua. Este trabajo intentará dar la vuelta a ese razonamiento y, centrándose en la inteligencia artificial, tratará de plantear criterios adecuados para que esa tecnología y muchas otras sean desarrolladas y aplicadas de forma adecuada a los derechos fundamentales en general y a la privacidad en particular. (...) Dentro de esos criterios se analizará lo que debe aportar la explicabilidad de la tecnología mencionada y se profundizará en algunos conceptos adicionales como la posibilidad y la necesidad de controlar y de auditar sistemas de inteligencia artificial. Para realizar la mencionada profundización se recurrirá a lo que se conoce como objetivos de protección y a los principios de la ciberética, incluyendo una referencia especial a la sostenibilidad y a la resiliencia de este tipo de sistemas.

BackgroundResearch during 2020 has been rapidly attending to the impact of COVID-19 on various dimensions of wellbeing on adults and children around the world. However, less attention has focused on the psychoeducational impact on children and their families. To our knowledge, no currently available studies have looked specifically at the impact of COVID-19 on students with dyslexia and their families. Research on this topic is needed to offer greater support for this population of students and their families.ObjectiveThe main objective of (...) this paper is to examine the psychoeducational impact of the required COVID-19 quarantine in Spain among children with dyslexia and their families.MethodA sample of 32 children with dyslexia and their mothers participated in this study.MeasuresChildren and adolescents with dyslexia and their mother completed several measures before the required national quarantine in Spain and again during the quarantine. Children completed measures of depression, state anxiety, reading activity, and reading motivation. Mothers provided demographic information and completed measures related to students’ emotional and behavioral difficulties as well as parenting stress, parental distress, and a questionnaire about educational problems during quarantine.ResultsMajor findings showed that during quarantine, children with dyslexia had increased levels of depression and anxiety symptoms, and parents perceived their children as having more emotional symptoms, hyperactivity-inattention, and conduct problems. During quarantine, children and adolescents with dyslexia also showed less reading activity and less reading motivation. Parents also reported significantly more stress, during quarantine compared to pre-quarantine conditions. Some demographic and psychological variables predicted children’s state anxiety as well parental stress. The questionnaire related to impacts of quarantine also revealed several important findings. For example, nearly all parents of children with dyslexia reported difficulties in establishing study routines, that the quarantine negatively affected their child’s learning, and that they did not receive sufficient help from teachers on how to support their child’s learning. Additionally, the vast majority of the parents were very worried about the child’s learning and school success, the child’s motivation and interest in reading, the child’s peer relations, and the professional skills of the child’s teacher.ConclusionThis study offers a preliminary investigation into this topic and elucidates several psychoeducational challenges that children with dyslexia and their families have experienced during the quarantine in Spain. Study findings highlight the need to provide immediate support for children with dyslexia and emphasizes the importance of developing prevention programs to mitigate any future negative impacts of COVID-19 on children with dyslexia and their parents.

El presente artículo tiene por objetivo plantear la pregunta por la técnica económica en el sentido heideggeriano del preguntar. Con “sentido heideggeriano” nos referimos al modo en el que Heidegger plantea la pregunta por la técnica a partir de la perturbación que provoca la técnica moderna. En otras palabras, nos preguntamos por “la” técnica económica inspirados por las consecuencias – pasadas, actuales y potenciales – de la técnica económica moderna: la economía de mercado. El trabajo procederá de la siguiente manera. (...) En primer lugar, planteamos la pregunta por la técnica económica explicando los motivos que nos llevan a ella y la inspiración heideggeriana de esta pregunta. En particular, apuntamos al fenómeno de la crisis económica en su sentido contemporáneo. En segundo lugar, buscaremos mostrar que, tal como hizo Heidegger con la técnica, no es posible hablar de “la” economía, sino que será necesario distinguir entre una economía antigua y una economía moderna. En tercer lugar, recurriremos al estudio histórico-antropológico de Karl Polanyi para describir la distinción entre ambos modos de concebir lo económico. En cuarto lugar, a partir de la descripción anterior mostraremos que la economía de mercado no es un mero instrumento para la producción de condiciones materiales, pues está caracterizada por una esencia provocante. Finalmente, concluiremos en torno a las consecuencias y posibilidades de esta descripción filosófica de la economía de mercado. Palabras clave: Economía de mercado, Martin Heidegger, Karl Polanyi, Filosofía de la economía. (shrink)

"La escuela moderna", de Francisco Ferrer Guardia. Francisco Ferrer Guardia fue un famoso pedagogo libertario español (1859-1909).

The ability to recognize a face is crucial for the success of social interactions. Understanding the visual processes underlying this ability has been the focus of a long tradition of research. Recent advances in the field have revealed that individuals having different cultural backgrounds differ in the type of visual information they use for face processing. However, the mechanisms that underpin these differences remain unknown. Here, we revisit recent findings highlighting group differences in face processing. Then, we integrate these results (...) in a model of visual categorization developed in the field of psychophysics: the RAP framework. On the basis of this framework, we discuss potential mechanisms, whether face-specific or not, that may underlie cross-cultural differences in face perception. (shrink)

This study investigates the procedural learning, retention, and reactivation of temporal sensorimotor sequences in children with and without developmental coordination disorder. Twenty typically-developing children and 12 children with DCD took part in this study. The children were required to tap on a keyboard, synchronizing with auditory or visual stimuli presented as an isochronous temporal sequence, and practice non-isochronous temporal sequences to memorize them. Immediate and delayed retention of the audio-motor and visuo-motor non-isochronous sequences were tested by removing auditory or visual (...) stimuli immediately after practice and after a delay of 2 h. A reactivation test involved reintroducing the auditory and visual stimuli after the delayed recall. Data were computed via circular analyses to obtain asynchrony, the stability of synchronization and errors. Firstly, an overall deficit in synchronization with both auditory and visual isochronous stimuli was observed in DCD children compared to TD children. During practice, further improvements were found for the audio-motor non-isochronous sequence compared to the visuo-motor non-isochronous sequence in both TD children and children with DCD. However, a drastic increase in errors occurred in children with DCD during immediate retention as soon as the auditory stimuli were removed. Reintroducing auditory stimuli decreased errors in the audio-motor sequence for children with DCD. Such changes were not seen for the visuo-motor non-isochronous sequence, which was equally learned, retained and reactivated in DCD and TD children. All these results suggest that TD children benefit from both auditory and visual stimuli to memorize the sequence, whereas children with DCD seem to present a deficit in integrating an audio-motor sequence in their memory. The immediate effect of reactivation suggests a specific dependency on auditory information in DCD. Contrary to the audio-motor sequence, the visuo-motor sequence was both learned and retained in children with DCD. This suggests that visual stimuli could be the best information for memorizing a temporal sequence in DCD. All these results are discussed in terms of a specific audio-motor coupling deficit in DCD.
