Cosas que usted no tuvo ocasión de preguntar sobre el aprendizaje y la enseñanza del lenguaje escrito a alumnos con NEE

En formato coloquial y de entrevista las autoras nos cuentan su proceso de reflexión didáctica para lograr una innovación general del modo y perspectiva para enseñar el lenguaje escrito, pasando desde un método tradicional basado en la enseñanza de un repertorio fonético y gráfico, a una enseñanza basada en la interacción y comprensión del propio proceso de escribir y leer, que resultó estar también perfectamente al alcance de los niños con necesidades educativas especiales.     

Identidad docente y estrategias de resolución de incidentes críticos en contextos universitarios de alta diversidad sociocultural

Resumen

Este estudio identifica las estrategias de los profesores cuando se enfrentan a incidentes críticos (IC) en contextos de alta diversidad sociocultural, reconociendo el peso de la identidad y de las emociones en la toma de decisiones, así como la efectividad de las mismas para promover cambios en las prácticas docentes. En el estudio de naturaleza cualitativa, fueron entrevistados 23 profesores universitarios. Los resultados indican que las emociones asociadas a un IC, generan una situación de desequilibrio que puede obstaculizar la actividad cuando son de naturaleza negativa. Al mismo tiempo, en estas situaciones es posible la revisión y reconstrucción de la propia identidad docente. En cuanto a las estrategias empleadas por los docentes ante los IC, éstas fueron mayoritariamente inmediatas e incidieron en aspectos muy puntuales, lo que derivó en actuaciones reactivas y poco eficaces. Pese a ello, la mayoría de los profesores no modificaron sus posiciones iniciales y fueron excepcionales las situaciones en las que el despliegue de estrategias y la reflexión posterior a un determinado IC permitió cambios estructurales que impactaron en alguna dimensión de la identidad del profesor como sus emociones y prácticas.     

Subjective Well-Being Decreasing With Age: New Research on Children Over 8

An increasing number of scientific publications have provided data from different countries suggesting subjective well-being (SWB) continuously decreases during adolescence. A review of these publications reveals authors have used dissimilar scales in diverse countries. Using data from the international Children's Worlds project (N = 48,040), involving 15 countries, a comparative analysis was performed to determine how mean scores evolve with different SWB scales from the age of 8 onwards. The results support the hypothesis that the tendency of SWB to decrease with age starts at around 10 years of age in most countries, while also confirming that different psychometric scales display different levels of sensitivity to diverse sociocultural contexts and more than one should be used in any research on children and adolescents’ SWB.     

Changes in Cortical Sensitivity to Infant Facial Cues From Pregnancy to Motherhood Predict Mother–Infant Bonding

The transition to motherhood triggers changes in human brain structure that may facilitate mother–infant bonding. Although much research on maternal cortical responses to infant faces has focused on the postpartum period, no previous study has examined whether longitudinal functional changes in the maternal cortex during pregnancy and postpartum are associated with mother–infant bonding. Using electroencephalography, prenatal to postnatal changes in cortical sensitivity (P1, P2, late positive potential, N170 event-related potentials) to infant and adult faces were examined in relation to reported mother–infant bonding in 40 mothers (M_age = 30.5 years). Prenatal to postnatal increases in P1 and P2 responses to infant faces predicted stronger bonding. Findings suggest that cortical changes in attention allocation rather than in face-specific encoding enhance bonding.     

Innovation and network multiplexity: R&D and the concurrent effects of two collaboration networks in an emerging economy

This study focuses on the multiplexity of firm R&D networks, and it investigates two types of boundary-spanning networks: the bipartite network between firms and government-sponsored institutions (GSIs), and the traditional firm–firm network. We apply a social network perspective to examine the effects that these kinds of networks have on firm innovativeness, in relation to the effects of the firm’s internal R&D efforts. We define the firm-GSI network as bipartite, and we investigate how the structural characteristics of this network (cohesion and centrality) affect innovativeness. We then decompose the innovational effects of firm–firm networks into two categories (intra- and inter-sector) to distinguish the effects of these collaboration networks. Furthermore, we investigate how these various external collaborative networks interact with a firm’s internal R&D efforts for driving innovativeness. Our empirical study of 420 manufacturing firms in Mexico evaluates evidence from surveys and secondary data. The findings indicate that the structural properties of both firm–GSI and firm–firm networks have positive effects on innovativeness, but firm–GSI network cohesion has a stronger negative interaction with R&D in influencing firm innovativeness. Moreover, intra-sector centrality in a firm–firm network has a stronger negative interaction with R&D than inter-sector centrality does in driving firm innovativeness. We contribute to the literature by integrating insights from the perspectives of network multiplexity, social embeddedness, and resource complementarity in regard to inter-organizational behavior. Our study also provides meaningful guidelines for both managers and policy makers. The study’s findings are robust to concerns of common method bias and alternative model specifications.     

Sleep Disturbance and Expressive Language Development in Preschool‐Age Children With Down Syndrome

Recent evidence has suggested that sleep may facilitate language learning. This study examined variation in language ability in 29 toddlers with Down syndrome (DS) in relation to levels of sleep disruption. Toddlers with DS and poor sleep (66%, n = 19) showed greater deficits on parent‐reported and objective measures of language, including vocabulary and syntax. Correlations between sleep and language were found in groups with equivalent medical and social backgrounds and after control for relevant behavioral comorbidities, including autism symptoms. These results emphasize the important role of quality sleep in all children's expressive language development, and may help increase our understanding of the etiology of language deficits in developmental disorders, potentially leading to new treatment approaches.     

Historical evolution of technological diversification

A positive relationship exists between national technological size and technological diversification across fields of innovative activity. This paper shows how the nature of this relationship has changed historically. There has been a downward structural shift in the cross-country size-diversification frontier since 1965—for any given size countries have become less diversified or more narrowly concentrated in their technological specialisation. One explanation is that international technology sourcing by MNEs has led locations to focus on what they do best. A supporting factor may be a rise in technological interrelatedness, which encourages focus upon a specific selection of complementary combinations.     

Evaluation of body composition with bioimpedence. A comparison between athletic and non-athletic children

Purpose: Conventional Bioelectrical Impedance Analysis (BIA) or Bioelectrical Impedance Vector Analysis (BIVA) can provide direct evaluations of body composition. The purpose of this study was to evaluate lean and fat mass (FM), and hydration of children involved in daily competitive sports. Methods: 190 non-athletic [8.2–10.5 years] and 29 competitive children [8.0–10.5 years] were enrolled. They were evaluated: at baseline (t0), 6 months (t1) and one year (t2). Anthropometric, BIA and BIVA, lean and FM, and hydration evaluations were performed. Results: Resistance (R/h) and reactance (Xc/h) were lower at t0 in competitive individuals when compared to controls. Xc/h (+3.28) significantly increases in competitive when compared to non-competitive individuals (+0.66, p for difference: 0.011), while phase angle (PA) was lower at t0 (5.72 vs. 6.17, p?<?.001) and after 6 months (p?=?.001). Total body water adjusted for height (TBW/h) significantly increased only in non-athletes (+0.50?±?0.13, p?<?.001) between t0 and t1. At t1, extracellular water (ECW) significantly decreased (p?=?.026) in the two groups: ?0.45?±?0.19% in non-competitive, ?1.63?±?0.49% in competitive subjects, while intracellular water (ICW) increased. At one-year follow-up (t2), there were no statistically significant differences in R/h, Xc/h and PA in competitive individuals when compared to baseline and t1. Furthermore, we observed at t2 that hours/week of training, age, male gender and body mass index can influence FFM/h and FM/h in both competitive and non-competitive subjects. In particular, a direct correlation was for hours/week and FFM/h, inverse for hours/week and FM/h. Conclusions: Body mass index does not allow evaluating differences in lean body mass and FM between athletes and non-athletes. BIA and BIVA can give more reliable details about body composition differences in competitive adolescents and non-competitive, outlining a progressive decline in ECW and increase in ICW without affecting TBW composition of athletes.     

Study and Conservation of the St. Nicola's Basilica Mosaics (Bari,Italy) by Photogrammetric Survey: Mapping of Polychrome Marbles,Decorative Patterns and Past Restorations

ABSTRACT

This present work focuses on the mapping of marbles, decorative patterns and area of the mosaics of the St. Nicola’s Basilica in Bari (Italy) by their photogrammetric survey. The extraordinary importance of these mosaics is due to the stylistic uniqueness and the undisputed workmanship and to the employed materials for tesserae. These mosaics include the white and polychrome marbles, used in the Roman age and reused in medieval artistic production, and imitation stones used as substitutes during the past restorations. The digital survey was realised by the photogrammetric reconstruction of mosaics collecting a photo dataset, after the mosaics redrawing by an image processing software and finally implemented it with lithological identification marbles. It allowed to obtain a punctual mapping of materials, through which to identify original areas and restoration areas, decorative patterns, recurring geometries. The research carried out, supported by the photogrammetric reconstruction as established method for high resolution digital reproduction and mapping, not only ensures the conservation and improvement of the enjoyment of the mosaic floors of the St. Nicola’s Basilica, but allows to conduct studies on materials, decorative patterns and restoration areas directly on the digitized product.     

Learning to become an intercultural practitioner： The case of lifelong learning intensive programme Interdisciplinary Course of Intercultural Competences

This paper dates back to 2009 （it was first presented at the CRLL Conference at Stirling University） and deals with the advances in lifelong learning introduced by an ERASMUS LLP--IP named Interdisciplinary Course of Intercultural Competences （ICIC）. The programme, that involves academic and non-academic institutions concerned with higher education of six different European countries, worked out an intensive international learning pathway aimed at developing intercultural competences in three professional fields： education, social work and health care. The paper focuses on the programme＇s innovative combination of formal and informal learning as a strategic lever to： （1） enhance a holistic concept of ＂competence＂ that puts human relationship at the centre of professional skills; （2） assume intercultural competences as key competences transversal to different professions; （3） introduce social skills and reflection as key factors for developing a transformative model of lifelong learning （Jarvis, 2005） that able to match the needs of the current complex, ever-changing societies; and （4） develop experiential learning without giving up to a strong theoretical framework of reference. The programme introduces an educational model that matches the main goals of higher educational priorities started by Bologna Process and relies upon a solid theoretical framework developed in the field of intercultural research at a sociological, socio-psychological and pedagogical level （Bennett, 1993; Gudykunst ＆ Ting, 2002; Camilleri ＆ Cohen, 1989; Hall, 1959; Hofstede 2001; Beck ＆ Grande, 2006; Farr, 1984）, as well as in one of the lifelong learning （Le Boteurf, 1997; Illeris, 2005; Jarvis, 2005; Schon, 1983）.
