Who is a native signer? Since around 95% of deaf infants are born into a hearing family, deaf signers are exposed to a sign language at various moments of their life, and not only from birth. Moreover, the linguistic input they are exposed to is not always a fully fledged natural sign language. In this situation, is the notion of native signer as someone exposed to language from birth of any use? We review the results of the first large-scale cross-linguistic (...) investigation on the effects of age of exposure to sign language. This research involved about 45 Deaf adult signers in each of three sign languages (Catalan Sign Language, French Sign Language, and Italian Sign Language). Across the three languages, participants were divided into three groups – those exposed from birth, those between 1 and 5 years of age, and those exposed between 6 and 15 years of age – and received a battery of tests designed for each language targeting various aspects of morphosyntactic competence. In particular, the tests focused on both those morphosyntactic phenomena that are known from the spoken language literature to be good detectors of language impairment or delay (i.e.,wh-interrogatives and relative clauses) and on morphosyntactic phenomena that are sign language specific (i.e., role shift and directional verbs). The results showed a clear effect of being native, with significant differences across languages and tests between signers exposed to sign language from birth and those exposed in the 1st years of life. This confirms the life-long importance of language exposure from birth and the reliability of the notion of “nativeness”, at least for syntax. On the other hand, while in most domains the differences observed between populations might be differences in performance, for some specific constructions, signers belonging to the three groups may have different grammars. This latter finding challenges the generalized use of native signers’ grammar as the baseline for language description and language assessment. (shrink)

Los procesos migratorios suponen repensar las relaciones, tránsitos y vivencias de las comunidades receptoras. En este sentido, el análisis de los escenarios de convivencia urbana implica redescubrir las historias viejas y nuevas de la inmigración, de la construcción del barrio, de la conformación de sus actores colectivos y de los espacios urbanos comunes. En el análisis de los escenarios de convivencia más conflictivos, encontramos giros discursivos que buscan responsabilizar a la inmigración reciente de problemáticas estructurales que se viven como irremediables. (...) Otros discursos, tendientes a la indiferencia respecto a la convivencia, muestran un potencial conflicto que vuelve inestables estas posturas. El escenario de convivencia social parece construirse desde acciones que buscan la implicación e interrelación entre los actores, desde el conocimiento y reconocimiento de las diferencias y con acento en los derechos comunes.

IntroductionThe prefrontal cortex plays a crucial role in cognition, particularly in executive functions. Cortical reactivity measured with Transcranial Magnetic Stimulation combined with Electroencephalography is altered in pathological conditions, and it may also be a marker of cognitive status in middle-aged adults. In this study, we investigated the associations between cognitive measures and TMS evoked EEG reactivity and explored whether the effects of this relationship were related to neurofilament light chain levels, a marker of neuroaxonal damage.MethodsFifty two healthy middle-aged adults from (...) the Barcelona Brain Health Initiative cohort underwent TMS-EEG, a comprehensive neuropsychological assessment, and a blood test for NfL levels. Global and Local Mean-Field Power, two measures of cortical reactivity, were quantified after left prefrontal cortex stimulation, and cognition was set as the outcome of the regression analysis. The left inferior parietal lobe was used as a control stimulation condition.ResultsLocal reactivity was significantly associated with working memory and reasoning only after L-PFC stimulation. No associations were found between NfL and cognition. These specific associations were independent of the status of neuroaxonal damage indexed by the NfL biomarker and remained after adjusting for age, biological sex, and education.ConclusionOur results demonstrate that TMS evoked EEG reactivity at the L-PFC, but not the L-IPL, is related to the cognitive status of middle-aged individuals and independent of NfL levels, and may become a valuable biomarker of frontal lobe-associated cognitive function.

Siete historias lógicas y un cuento breve contiene ocho aproximaciones a la obra lógica y epistemológica de Manuel Sacristán Luzón (1925-1985) cuya Introducción a la lógica y al análisis formal fue, tal como ha señalado Luis Vega Reñón, un libro esencial en los años sesenta del pasado siglo para la consolidación de los estudios de lógica y de filosofía de la lógica en nuestro país. Se incluyen en estas historias, lógicas y político-culturales, las cartas cruzadas entre Sacristán y algunos de (...) los grandes filósofos y lingüistas de nuestro país como Víctor Sánchez de Zavala, Juan David García Bacca, Miguel Sánchez-Mazas y Josep Ferrater Mora. Se incluyen también sendos capítulos sobre la correspondencia con Ludovico Geymonat y Salvador Espriu y una aproximación al papel de la lógica en la tesis de Sacristán sobre la gnoseología de Martin Heidegger, así como la presentación de un texto inédito interrumpido del traductor de Quine sobre la teoría del conocimiento y una aproximación a lo ocurrido en las oposiciones a la cátedra de lógica de la Universidad de Valencia de 1962.

BackgroundMonitoring recovery–stress balance in sport is becoming more relevant to prevent training maladaptation and reach the optimal performance for each athlete. The use of questionnaires that identify the athlete’s recovery–stress state have much acceptance in sports due to reliability and useful, furthermore for its low cost. Identifying possible differences between sport modalities and sex is important to determine specific needs and possible intervention ways to keep a recovery–stress balance. The aim was to analyze the differences in the recovery–stress state and (...) mood states by sex and sport type during the competitive phase in young Mexican athletes. As a secondary objective, the psychometric properties of the Mexican version of the Recovery–Stress Questionnaire for Athletes were analyzed.MethodsA cross-sectional study was carried on with 461 athletes, 17.95 years old, from six sports disciplines. The RESTQ-Sport and Profile of Mood States were applied in a single moment. Differences by sex and sports modality were analyzed. RESTQ-Sport’s confirmatory factor analysis was performed after the stress and recovery theoretical structure of two stress and two recovery dimensions, and last, the concurrent validation with the POMS was carried on.ResultsSignificant differences by sex were found in the General Recovery and Sport Stress dimensions of the RESTQ-Sport as well as Vigor factor of the POMS, being higher for men; furthermore, both the Sport Recovery dimension of RESTQ-Sport and Cholera and the Fatigue and Depression factors from POMS also had differences by sport type, showing a less recovery and high stress for individual sport athletes. Goodness-of-fit indexes of the model for the RESTQ-Sport were acceptable. Pearson’s correlation between questionnaires was moderate.ConclusionThe recovery–stress state shows differences in the function of sex and sport modality. More special attention is suggested for women and individual sport athletes. The higher punctuation for men compared with women in sport stress dimension did not negatively affect the recovery–stress balance for male athletes. Finally, the Mexican context adaptation of the RESTQ-Sport provides a psychometric instrument suitable to assess the recovery–stress balance in Mexican athletes. (shrink)

Quizá lo más fascinante de la ciencia no sean los misterios que consigue develar, sino los nuevos enigmas que surgen a partir de sus respuestas, de tal suerte que el quehacer científico es en realidad un continuo descubrimiento de nuevos campos de descubrimiento. Esta nueva compilación complementa el universo de temas que se abordaron en el primer volumen.

The present study aims to apply a program based on Hellison’s Teaching Personal and Social Responsibility Model (TPSR), traditionally used in Physical Education, to other educational subjects and examine the assessment of the teachers who carried it out during the 2018-2019 school year. The program was applied over eight months of one academic year and during at least 60% of the weekly class hours. Initially, 586 students participated, 429 being experimental subjects with 30 teachers, of whom 16 participated in the (...) interviews carried out, all of them being Secondary Education teachers. We used qualitative methodology through content analysis carried out with ATLAS.ti 7.1.3. The instruments used to collect information were semi-structured recorded group interviews. The conclusion is that the Personal and Social Responsibility Model can be applied to all subjects in the curriculum and is adaptable to any content and type of student body. As a basis for future research, we suggest the application of the model by all teachers involved in the same school year and the participation of students’ families. (shrink)

En la historia de la definición de su estilo artístico ocupa un lugar destacado el artista mexicano Miguel Covarrubias. En el artículo realizamos un análisis pormenorizado de su obra, intentando mostrar la evolución de sus ideas artísticas y la importancia que tuvieron a la hora de configurar lo que hoy se denomina «estética olmeca». Se analizan sus presupuestos teóricos y la enorme influencia que sus (...) tesis tienen, aun hoy, a la hora de analizar la que muchos consideran la «cultura madre» de Mesoamérica. (shrink)

The cross-cultural literature is reviewed and integrated together with attitude theories, thereby outlining a model through which certain values influence the intervening variables that ultimately lead managers to tolerate employee bribery. The case of Latin America is employed to illustrate how regionally dominant cultural values may shape managers' attitudes, subjective norms, and perceived behavioral control, which in turn affect tolerance of employee bribery. A series of research propositions and practical recommendations are derived from the model.

La Modernidad ha sido el escenario de su propia crisis ¿Acaso estaba ésta abocada a su quiebra? ¿Son la razón instrumental, el nazismo, el nihilismo o el capitalismo los hijos monstruosos de una Ilustración realizada? ¿Y el patriarcado?¿No ha sido también la razón una proclama masculina? Pretendemos defender que tanto la lucha feminista como el marxismo necesitan en el siglo XXI recuperar una Ilustración que no se ha realizado en la técnica, en los campos de concentración o en la nada (...) social que produce el capitalismo, sino en los resquicios rebeldes de una historia de vencedores y perdedores. La breve historia de la tradición republicana es la historia de una derrota política que la izquierda no debería olvidar. Se quiere, por tanto, defender a la Ilustración de ese olvido y, para ello, explicar qué sería una Ilustración republicana y en qué sentido es imprescindible —tanto para el feminismo como para el marxismo— en tiempos tan críticos.

Anàlisi crítica sobre les bases doctrinals de l'ecologisme. Idees i reflexions que trenquen els tòpics més divulgats.

La eclosión de las neurodisciplinas está conectada con el amplio y creciente uso de neuroimágenes en neurociencia cognitiva, en particular de las obtenidas mediante resonancia magnética funcional. Sin embargo, la aplicación de estudios sobre el cerebro basados en esta técnica a la filosofía, la ética o el derecho, entre otros campos, no es tan clara como a veces se supone y encuentra importantes limitaciones.
