Saúde mental e fatores emocionais nas campanhas brasileiras da semana mundial de aleitamento materno

The reduction of child mortality has been the focus of World Breastfeeding Week campaigns. On the other hand, breastfeeding and weaning are considered by psychoanalysis as key moments in the prophylaxis in mental health. Our goal is to investigate how the emotional aspects involved in breastfeeding have been addressed on the promotional material of Brazilian campaigns from 1999 (year of its creation) to 2010. The method adopted was the categorical content analysis and the results indicate that (1) the emotional benefits of breastfeeding are treated superficially, (2) weaning is depleted of its relational dimension (separation), being presented as a chronological and pragmatic concept, based on the introduction of new foods, (3) the term "mental health" is mentioned only once, without a precise definition. The relationship between breastfeeding and emotional development, besides the prophylaxis of mental health, has not been fully exploited in the analyzed campaigns.

Uma sinapse científica: a neurociência encontra a psicologia

The aim of this paper is to present aspects of the prominent findings of neuroscience in relation to psychological phenomena long studied in psychology. One of the basic points of this presentation is to show briefly the relationship between the anatomical and physiological structures linked to certain human behavior resulting from the evolution of species and the socio-emotional development of the individual.

Material didático para alunos surdos: a literatura infantil em Libras

The storytelling is central to the early literacy of children, part of the objectives for the entire kindergarten. The story circle or storytelling is important and helpful in cognitive and emotional development of children, including the ones with disabilities. Seeking communicational accessibility, the aim of this work is to make the book "O Penuginha" by Luiz Vitor Martinello available in LIBRAS (Brazilian Sign Language). To facilitate the achievement of this objective, it was considered appropriate to develop a descriptive study following the methodology of qualitative research, to search for literature on how learning takes place in the Portuguese language by deaf students. This study resulted in a DVD with video recordings, the translation of the book "O Penuginha" in LIBRAS and the narration of the book in Portuguese. Therefore, this research is relevant because the paradigm of the twenty first century is the inclusion of all people in different scenarios and the school is one of the first places where the removal of barriers is essential.

Autismo e família: revisão bibliográfica em bases de dados nacionais

Early studies involving childhood autism attributed to family involvement in impairment of psycho-emotional development of the child. The purpose of this study was to review the literature related to autism and family in two national databases (Theses Database of Capes and Scientific Electronic Library Online) without defining a specific period as well as identify the main thematic focused. Were located 29 studies in Theses Database of Capes, the first record in 1990 and 12 in Scientific Electronic Library Online, the first publication in 2001. The results were grouped into seven categories. The categories “Quality of Life” and “Family Relations” concentrate most of publications on Theses Database. Already in Scientific Electronic Library Online, mostly refers to the “Family Relations” and “literature review”. It was found that none of theses or dissertations was published in scientific paper format, hampering the dissemination of research in the area.

Autismo: aspectos cognitivos, educacionais e neurobiológicos com base na análise dos livros Mundo singular: entenda o autismo e o Os gatos nunca mentem sobre o amor e na literatura especializada

The autism is a severe mental illness that involves psychological, social, educational and neurobiological aspects. The Education plays an important role in recovering, preserving and increasing the cognitive task of people with autism. There are several ways to observe a person with autism. Through the studying of cases, it is also possible to address issues of everyday life of the person with the illness, its cognitive issues and its obstacles of psychosocial involvement, as well as psychological aspects such as illness acknowledgement. Through specialized literature, it is possible to identify characteristics referring to the learning process and neurobiological components involved in the condition, such as brain activity disorder and genetic factors. The objectives of this paper are: from the analysis of two books: Unique World: comprehend the Autism (SILVA, A. B. B; GAIATO, M.B; REVELES, L.T) and The cats never lie about love (DILLON, J.), it is intended to describe cognitive and psychosocial aspects of the autism. Based on the specialized literature, the goal is to identify cognitive and neurobiological components in the illness. The methods that were used: analysis of the books Unique World: comprehend the Autism and The cats never lie about love to describe psychosocial and educational aspects of the autism; analysis of the specialized literature to identify clinical and neurobiological components of the illness, such as changes in brain activity, genetic factors or clinical evolution; and also details of the Education role in preserving the person with autism and his cognitive and emotional development. The study had the documentary research as reference for the methodological design, including book analysis and research in specialized literature. It is intended to deepen discussions about the Education roles related to the cognitive and neurobiological aspects of the autism

The ontogenesis of smiling and its association with mothers` affective behaviors: A longitudinal study

Two babies were observed from their third week to their sixth month of life. Our goals in the study were: to investigate developmental changes in smiling patterns; to analyze the smiling patterns observed in the presence of mother`s affective behaviors, and to verify whether the babies can answer contingently, with smiles, to mothers` affective behaviors. The babies and their mothers were videotaped at home. It was verified a positive linear trajectory tendency for the babies` smiles. The babies revealed a particular tendency to display one or two kinds of smiles. Babies answered contingently with smiles to their mothers` affective behaviors. Correlations between the most frequent types of babies` smiles and his/her mothers` smiles were verified (r = 37, p < .0017 - baby1, and r = .62, p < .0017 - baby2). Different types of smiles were exhibited by the babies as contingent answers to mothers` behaviors. The results show an association between babies` smiles and their mothers` affective behaviors.

Regulation of woody plant development by auxin and polar auxin transport

Auxin is a key regulator in plant growth and development. This dissertation examines the role of auxin and polar auxin transport in woody growth and development. Strategies of promoter reporter system, microarray expression analysis, transgenic modification, physiological assays, anatomical analysis, and histochemical/biochemical assays were employed to improve our understanding of auxin study in Populus. The results demonstrate various aspects of auxin regulation on shoot growth, root development, wood formation, and gravitropism in woody tissues. We describe the behavior of the DR5 reporter system for measuring auxin concentrations and response in stably transformed Populus trees. Our study shows that DR5 reporter system can be efficiently used in Populus to study auxin biology at a cellular resolution. We investigated the global gene expression in responding to auxin in Populus root. The results revealed groups of IBA up- and down- regulated genes involved in various biological processes including cell wall modification, root growth and lateral root formation, transporter activity and hormone crosstalk. We also verify two of the identified genes' function by transgenic modification in Populus, which encode auxin efflux carrier PtPIN9 and transcription factor PtERF72. We investigated the role of PtPIN9 in woody growth and development, especially in wood formation and gravitropic response in woody stem. We found that overexpressing PtPIN9 enhanced several growth parameters while suppression of PtPIN9 has inhibited tension wood formation. Our results show that PIN9 and other members from PIN family could be possible useful tools for increasing biomass productivity, wood quality, or in modifying plant form.

Sozio-emotionale Entwicklung von Ganztagsschulkindern auf der Primarschulstufe

Im vorliegenden Beitrag wird die Entwicklung von Schülerinnen und Schülern aus Ganztagsschulen, welche die Angebote intensiv nutzen im Vergleich zu Schülerinnen und Schülern, die nur den Unterricht besuchen (Kontrollgruppe) bezüglich (a) des prosozialen Verhaltens und (b) der sozio-emotionalen Verhaltensstärken bzw. Verhaltensauffälligkeiten untersucht. Die Teilstichprobe umfasst N = 295 Schüler aus 43 Primarschulklassen und 35 Schulen in der Deutschschweiz, die im Rahmen einer quasi-experimentellen Längsschnittstudie in den ersten drei Primarschuljahren untersucht wurden. Die Ergebnisse zeigen, dass es der Ganztagsschule insgesamt nicht gelingt, die Entwicklung des prosozialen Verhaltens oder der sozio-emotionalen Verhaltensstärken der Schülerinnen und Schüler positiv zu beeinflussen. Im Weiteren bestätigen die Befunde einen Zusammenhang zwischen der pädagogischen Qualität der Ganztagsschulangebote und der sozio-emotionalen Entwicklung von Primarschulkindern.

Chipping Away at the Monolith: Dispelling the Myth of Father Noninvolvement in Children's Early Literacy Development

Current research stresses the importance of parent involvement in their children 's academic development. Parents reading and writing with their young children is shown to prepare them for the benefits of for ma I education. Studies completed on parent participation in early literacy activities have tended to look at mothers ' role. Few researchers have investigated the contributions fathers have made. The results of a study completed on father-child early literacy practices are presented. Fathers reported engaging in reading and writing activities with their children for three reasons: To prepare their children for school, to bond with their children, and to assist their children in language skill development. Recommendations are provided on how to encourage fathers to participate in early literacy practices

Protect Children From Household Food Insecurity: Promote Access To Food and Stress-Alleviating Resources

Household food insecurity is associated with threats to children’s intellectual, behavioral, and psycho-emotional development. In addition to poor food quality and quantity, the stress associated with food insecurity can undermine caregiver mental health and family functioning. Evidence demonstrates that national assistance programs and policies are needed to ensure that families and children have access to adequate sources of healthy food and to stress-alleviating resources.

Impairment of rat postnatal lung alveolar development by glucocorticoids: involvement of the p21CIP1 and p27KIP1 cyclin-dependent kinase inhibitors

It has been shown that glucocorticoids accelerate lung development by limiting alveolar formation resulting from a premature maturation of the alveolar septa. Based on these data, the aim of the present work was to analyze the influence of dexamethasone on cell cycle control mechanisms during postnatal lung development. Cell proliferation is regulated by a network of signaling pathways that converge to the key regulator of cell cycle machinery: the cyclin-dependent kinase (CDK) system. The activity of the various cyclin/CDK complexes can be modulated by the levels of the cyclins and their CDKs, and by expression of specific CDK inhibitors (CKIs). In the present study, newborn rats were given a 4-d treatment with dexamethasone (0.1-0.01 microg/g body weight dexamethasone sodium phosphate daily on d 1-4), or saline. Morphologically, the treatment caused a significant thinning of the septa and an acceleration of lung maturation on d 4. Study of cyclin/CDK system at d 1-36 documented a transient down-regulation of cyclin/CDK complex activities at d 4 in the dexamethasone-treated animals. Analysis of the mechanisms involved suggested a role for the CKIs p21CIP1 and p27KIP1. Indeed, we observed an increase in p21CIP1 and p27KIP1 protein levels on d 4 in the dexamethasone-treated animals. By contrast, no variations in either cyclin and CDK expression, or cyclin/CDK complex formation could be documented. We conclude that glucocorticoids may accelerate lung maturation by influencing cell cycle control mechanisms, mainly through impairment of G1 cyclin/CDK complex activation.

Cognition and Student Learning Through the Arts

An increasing number of recent research studies suggest connections between cognition, social and emotional development, and the arts. Some studies indicate that students in schools where the arts are an integral part of the academic program tend to do better in school than those students where that is not the case. This study examines home/school factors that contribute most to variance in student learning and achievement and the arts from over 8,000 students in grade 5. The findings suggest in-school arts programs may have less of an impact on student achievement than proposed by previous research.
