''Maria da Penha vai à escola?'' Representações sociais de jovens do ensino médio sobre a violência doméstica contra a mulher

RESUMO:Este trabalho teve como objetivo identificar as Representações Sociais dos jovens do Ensino Médio sobre a Violência Doméstica Contra a Mulher. A metodologia deste estudo investigativo foi pautada sobre os pilares da pesquisa qualitativa de caráter exploratório e descritivo. A primeira série do ensino médio, de duas escolas localizadas no centro da cidade de João Pessoa, uma da instância pública estadual e outra de capital privado, constituiu o universo da pesquisa. Os sujeitos 12 meninos e 12 meninas abrangeram a faixa etária entre 14 e 20 anos de idade. O marco teórico foi sistematizado de forma a atender os questionamentos pertinentes à pesquisa e composto de estudiosos e pesquisadores nas áreas das Representações Sociais, da Violência Doméstica Contra a Mulher e sobre a Lei Maria da Penha. O grupo focal, a entrevista semi-estruturada e a análise de conteúdo foram os instrumentos utilizados para a coleta e análise dos dados recolhidos. As informações e dados coletados foram organizados de acordo com as técnicas de grupo realizadas nas oficinas de ideias dos dois encontros do grupo focal e as entrevistas individuais. A partir da análise dos resultados verificou-se nas representações sociais dos jovens da 1ª série do ensino médio sobre a violência doméstica contra a mulher que eles têm consciência da gravidade social que esta conduta delitiva representa. Mostram estar cientes das causas e consequências deste tipo de violência, sabendo também apontar medidas preventivas em âmbito escolar e social de um modo geral além de saber atribuir competências a órgãos públicos nesta tarefa. ABSTRACT: This work was developed to identify the Social Representations of young high school students about domestic violence against women. The methodology of this investigative study was based on qualitative research pillars of exploratory and descriptive kind. The first year of high school, from two schools located in the centre of João Pessoa city, one public and another private composed the search universe. The subjects were 12 boys and 12 girls from the age of 14 to 20. The theoretical mark was systematized to meet relevance to research inquiries and was composed by scholars and researchers in the areas of Social Representations Theory, Domestic Violence Against Women and Maria da Penha Law. Focus group, semi-structured interview and analysis content were instruments used for compilation and analysis of data collected. The information and data collected have been organized according to techniques of group performed in the workshops of ideas during the two focal group meetings and individual interviews. Based on the analysis of results found through Social Representations Theory in young people of 1st grade high school about domestic violence against women, they are aware of the social gravity that this delictive conduct represents, demonstrate to be conscious of causes and consequences of this kind of violence and make out preventive measures in scholastic and social reach in a general view, besides the attribution of skills to public agencies concerning this task.

A supervisão pedagógica e o trabalho colaborativo na promoção do desenvolvimento profissional dos professores do grupo de Física e Química

Numa escola que se encontra em transformação no sentido de se adaptar aos contextos sociais, culturais e políticos que a rodeiam, cabe aos professores serem agentes ativos na definição do caminho a percorrer, visando o aumento da qualidade educativa a proporcionar aos nossos jovens. O questionamento inerente à reflexão sobre o percurso profissional levou à identificação da situação problema e à formulação daquela que é a questão de partida deste trabalho: Como é que a Supervisão Pedagógica (e o trabalho colaborativo a ela associado) poderá contribuir para a melhoria da reflexão conjunta entre os professores do Grupo Disciplinar de Física e Química, promovendo o seu desenvolvimento Profissional? Para dar resposta a esta questão, elaborámos o enquadramento teórico, orientado pelas palavras-chave e com recurso a autores de referência, no qual pretendemos salientar as principais investigações que conferem suporte às temáticas subjacentes a este trabalho: a reflexão interpares na promoção do desenvolvimento profissional dos professores, a Supervisão pedagógica e a importância da formação docente e do trabalho colaborativo na qualidade educativa. Como o objetivo geral do trabalho de projeto é conceber um Projeto de Intervenção de Supervisão Pedagógica no Grupo Disciplinar de Física e Química, visando a melhoria do trabalho colaborativo, a promoção das atitudes reflexivas e investigativas dos docentes e o seu desenvolvimento profissional, a terceira parte foi estruturada com base nos princípios subjacentes à metodologia de projeto. Recolhemos opiniões através de Inquéritos por Questionário, realizados a todos os professores do grupo, e através de Entrevistas, realizadas apenas às professoras Coordenadora e Subcoordenadora do Departamento de Matemática e das Ciências Experimentais, da Escola Secundária Rosa. O Projeto de Intervenção de Supervisão Pedagógica deverá ser implementado e desenvolvido no Grupo Disciplinar de Física e Química da escola referida e com ele pretendemos aprofundar as práticas supervisivas e colaborativas entre os docentes, através da realização de Ciclos completos de Supervisão Pedagógica, de acordo com as fases preconizadas por Goldhammer.

O ensino da língua portuguesa e a linguagem na comunicação virtual: alternativas e dilemas

A presente investigação tem como objetivo compreender como os professores de Língua Portuguesa integram a linguagem da comunicação pela Internet em sua prática pedagógica, uma vez que a linguagem utilizada na comunicação virtual demonstra variações linguísticas na expectativa oposta a Língua Portuguesa em sua forma padrão e, neste contexto, a escola e o professor de português representam intermédios possíveis entre o escrito padrão e o virtual. Após processo investigativo que contou com recolha de dados documentais e entrevistas semiestruturadas, constata-se que os professores de Língua Portuguesa ressaltam as diferenças da linguagem na comunicação pela Internet em relação à forma padrão na mesma precisão em que defendem o uso da tecnologia no ambiente escolar. Afirmam que, neste contexto, o papel do professor de português concentra-se no preparo do estudante para o uso da forma padrão, permitindo uma abertura em sua prática à linguagem na comunicação virtual. Neste sentido, defendem que o posicionamento adequado do professor de Língua Portuguesa diante do ensino da língua padrão e sua relação com a linguagem virtual, centraliza-se numa abertura para um estudo linguístico na perspectiva dos possíveis usos sociais da língua, possuindo como referencial a forma padrão da Língua Portuguesa.

O ensino-aprendizagem da física e da química: manuais escolares versus recursos digitais

Nesta dissertação investigamos o uso do manual escolar na sala de aula, em consonância com as mudanças das práticas pedagógicas resultantes da existência de novos recursos digitais agregados ao manual escolar, tais como o e-manual, os CD-ROM e DVDs e, as plataformas educacionais na Internet, em particular, a Escola Virtual, da Porto Editora. O leitmotiv da realização desta investigação é avaliar a utilização destes recursos, quer nas práticas pedagógicas inovadoras por parte dos docentes, quer na contribuição para melhorar a aprendizagem dos alunos. No sentido de melhor compreender e analisar o impacto da integração dos recursos digitais no ensino-aprendizagem, escolhemos os recursos da Porto Editora, visto tratar-se de um estudo de caso centrado numa escola que adotou estes recursos. A partir de um enquadramento metodológico que procura ultrapassar as dicotomias entre as abordagens quantitativas e as abordagens qualitativas, centramos o nosso estudo numa unidade didática, Astronomia, lecionada no 7º ano de escolaridade, na disciplina de Ciências Físico-Químicas. Com base num modelo heurístico, os dados recolhidos através de questionários a professores e alunos numa escola onde a investigadora estagiou, referente a este conteúdo, indicam que a utilização dos referidos recursos digitais no ensino-aprendizagem, fomentou a motivação para a realização de atividades propostas, facilitou a compreensão e a aprendizagem de conceitos e motivou os alunos para o estudo na disciplina de Ciências Físico-Químicas. Não podemos deixar de enfatizar a exploração do manual interativo, como um elemento extremamente inovador, e simultaneamente potenciador da disseminação de conhecimentos em espaços não convencionais de ensino, pela possibilidade de autoaprendizagem, respeitando as particularidades dos alunos. No entendimento de uma postura de abertura e de investigação permanente e, conscientes de que o ensino-aprendizagem engloba inúmeros fatores, apontamos alguns trajetos investigativos possíveis que poderão, eventualmente, despontar, a partir deste estudo. 

Dziedzictwo IRE: współczesny model samoorganizacji dziennikarzy śledczych na świecie

Artykuł jest próbą odpowiedzi na pytanie o wpływ modelu organizacyjnego Investigative Reporters and Editors na powstające od kilku dekad na całym świecie stowarzyszenia dziennikarzy śledczych. Autor omawia rozwój struktur zrzeszających reporterów dochodzeniowych w różnych państwach, w szczególności przyjętych przez nie form działania oraz celów. Rosnąca liczba oraz globalny charakter tego zjawiska prowadzi do instytucjonalizacji dziennikarstwa śledczego na świecie. Scharakteryzowane zostały w artykule wybrane organizacje, w szczególności te, które zaadaptowały model wypracowany przez IRE. W odniesieniu do pozostałych stowarzyszeń dziennikarskich autor wskazuje na przyczyny odrzucenia formuły wypracowanej przez amerykańskich muckrakerów.

El entenao, de Alfredo Pareja Diezcanseco, y la afirmación de la cultura montuvia como componente integral de lo nacional (Del Fabulador)

El autor estudia el poema que Alfredo Pareja escribiera en 1935, El entenao, dentro del proyecto literario y social del Grupo de Guayaquil, ya que presenta los valores del montuvio y lo muestra como víctima de un sistema de justicia que ampara la usurpación y el abuso de los poderosos (el entenado es una figura de orígenes paternos inciertos, que simboliza el abandono y menosprecio con que se mira al montuvio). El proyecto del Grupo, a pesar del empeño y los esfuerzos investigativos -que incluyeron la mirada desde la arqueología-, quedó luego estancado en «lo folclórico», durante décadas. Por ello tiene sentido la publicación de la obra en 1988, cuando el país inició un nuevo proceso de definición de lo nacional- esta vez en torno a la interculturalidad-, la publicación coincide y contribuye con este segundo esfuerzo por integrar la cultura montuvia en el escenario nacional.

Sociodemographic and nutritional correlates of neurobehavioral development: a study of young children in a rural region of Ecuador

To identify and describe the sociodemographic and nutritional characteristics associated with neurobehavioral development among young children living in three communities in the northeastern Andean region of Cayambe-Tabacundo, Ecuador. Women in the study communities who had a child 3 to 61 months of age completed a questionnaire about maternal and child health and sociodemographic characteristics. The Ages and Stages Questionnaire (ASQ) was directly administered to 283 children by two trained interviewers. Growth measurements and a hemoglobin finger-prick blood test were obtained in 2003–2004. Prevalence of developmental delay was calculated, and associations between child development and maternal, child, and household characteristics were explored. High frequencies of developmental delay were observed. Children 3 to 23 months old displayed delay in gross motor skills (30.1%), and children 48 to 61 months old displayed delay in problem-solving skills (73.4%) and fine motor skills (28.1%). A high frequency of both anemia (60.4%) and stunting (53.4%) was observed for all age groups. Maternal educational level was positively associated with communication and problem-solving skills, and monthly household income was positively associated with communication, gross motor, and problem-solving skills. The results suggest a high prevalence of developmental delay and poor child health in this population. Child health status and the child’s environment may contribute to developmental delay in this region of Ecuador, but sociodemographic factors affecting opportunities for stimulation may also play a role. Research is needed to identify what is causing high percentages of neurobehavioral developmental delay in this region of Ecuador.

A novel Bayesian approach to drug design with simple and complex enzymes: Use with lens aldehyde dehydrogenase and the glyoxalase pathway

Purpose: Acquiring details of kinetic parameters of enzymes is crucial to biochemical understanding, drug development, and clinical diagnosis in ocular diseases. The correct design of an experiment is critical to collecting data suitable for analysis, modelling and deriving the correct information. As classical design methods are not targeted to the more complex kinetics being frequently studied, attention is needed to estimate parameters of such models with low variance. Methods: We have developed Bayesian utility functions to minimise kinetic parameter variance involving differentiation of model expressions and matrix inversion. These have been applied to the simple kinetics of the enzymes in the glyoxalase pathway (of importance in posttranslational modification of proteins in cataract), and the complex kinetics of lens aldehyde dehydrogenase (also of relevance to cataract). Results: Our successful application of Bayesian statistics has allowed us to identify a set of rules for designing optimum kinetic experiments iteratively. Most importantly, the distribution of points in the range is critical; it is not simply a matter of even or multiple increases. At least 60 % must be below the KM (or plural if more than one dissociation constant) and 40% above. This choice halves the variance found using a simple even spread across the range.With both the glyoxalase system and lens aldehyde dehydrogenase we have significantly improved the variance of kinetic parameter estimation while reducing the number and costs of experiments. Conclusions: We have developed an optimal and iterative method for selecting features of design such as substrate range, number of measurements and choice of intermediate points. Our novel approach minimises parameter error and costs, and maximises experimental efficiency. It is applicable to many areas of ocular drug design, including receptor-ligand binding and immunoglobulin binding, and should be an important tool in ocular drug discovery.

Cannabinoids inhibit human keratinocyte proliferation through a non-CB1/CB2 mechanism and have a potential therapeutic value in the treatment of psoriasis

Background: Cannabinoids from cannabis (Cannabis sativa) are anti-inflammatory and have inhibitory effects on the proliferation of a number of tumorigenic cell lines, some of which are mediated via cannabinoid receptors. Cannabinoid (CB) receptors are present in human skin and anandamide, an endogenous CB receptor ligand, inhibits epidermal keratinocyte differentiation. Psoriasis is an inflammatory disease also characterised in part by epidermal keratinocyte hyper-proliferation. Objective: We investigated the plant cannabinoids Delta-9 tetrahydrocannabinol, cannabidiol, cannabinol and cannabigerol for their ability to inhibit the proliferation of a hyper-proliferating human keratinocyte cell line and for any involvement of cannabinoid receptors. Methods: A keratinocyte proliferation assay was used to assess the effect of treatment with cannabinoids. Cell integrity and metabolic competence confirmed using lactate-dehydrogenase and adenosine tri-phosphate assays. To determine the involvement of the receptors, specific agonist and antagonist were used in conjunction with some phytocannabinoids. Western blot and RT-PCR analysis confirmed presence of CB1 and CB2 receptors. Results: The cannabinoids tested all inhibited keratinocyte proliferation in a concentration-dependent manner. The selective CB2 receptor agonists JWH015 and BML190 elicited only partial inhibition, the non-selective CB agonist HU210 produced a concentration-dependent response, the activity of theses agonists were not blocked by either C81 /C82 antagonists. Conclusion: The results indicate that while CB receptors may have a circumstantial role in keratinocyte proliferation, they do not contribute significantly to this process. Our results show that cannabinoids inhibit keratinocyte proliferation, and therefore support a potential role for cannabinoids in the treatment of psoriasis.

A role for Notch signaling in human corneal epithelial cell differentiation and proliferation

PURPOSE. To identify the role of Notch signaling in the human corneal epithelium. METHODS. Localization of Notch1, Notch2, Delta1, and Jagged1 in the human corneal epithelium was observed with the use of indirect immunofluorescence microscopy. Gene and protein expression of Notch receptors and ligands in human corneal epithelial cells was determined by RT-PCR and Western blot analysis, respectively. The effects of Notch inhibition (by {gamma}-secretase inhibition) and activation (by recombinant Jagged1) on epithelial cell proliferation (Ki67) and differentiation (CK3) were analyzed after Western blotting and immunocytochemistry. RESULTS. Immunofluorescent labeling localized Notch1 and Notch2 to suprabasal epithelial cell layers, whereas Delta1 and Jagged1 were observed throughout the corneal epithelium. Notch1, Notch2, Delta1, and Jagged1 genes and proteins were expressed in human corneal epithelial cells. {gamma}-Secretase inhibition resulted in decreased Notch1 and Notch2 expression, with an accompanying decrease in Ki67 and increased CK3 expression. The activation of Notch by Jagged1 resulted in the upregulation of active forms of Notch1 and 2 proteins (P < 0.05), with a concurrent increase in Ki67 (P < 0.05) and a decrease in CK3 (P < 0.05) expression. Interestingly, {gamma}-secretase inhibition in a three-dimensional, stratified corneal epithelium equivalent had no effect on Ki67 or CK3 expression. In contrast, Jagged1 activation resulted in decreased CK3 expression (P < 0.05), though neither Notch activation nor inhibition affected cell proliferation in the 3D tissue equivalent. CONCLUSIONS. Notch family members and ligands are expressed in the human corneal epithelium and appear to play pivotal roles in corneal epithelial cell differentiation.

Can misalignments in typical infants be used as a model for infantile esotropia?

PURPOSE. To investigate the nature of early ocular misalignments in human infants to determine whether they can provide insight into the etiology of esotropia and, in particular, to examine the correlates of misalignments. METHODS. A remote haploscopic photorefraction system was used to measure accommodation and vergence in 146 infants between 0 and 12 months of age. Infants underwent photorefraction immediately after watching a target moving between two of five viewing distances (25, 33, 50, 100, and 200 cm). In some instances, infants were tested in two conditions: both eyes open and one eye occluded. The resultant data were screened for instances of large misalignments. Data were assessed to determine whether accommodative, retinal disparity, or other cues were associated with the occurrence of misalignments. RESULTS. The results showed that there was no correlation between accommodative behavior and misalignments. Infants were more likely to show misalignments when retinal disparity cues were removed through occlusion. They were also more likely to show misalignments immediately after the target moved from a near to a far position in comparison to far-to-near target movement. DISCUSSION. The data suggest that the prevalence of misalignments in infants of 2 to 3 months of age is decreased by the addition of retinal disparity cues to the stimulus. In addition, target movement away from the infant increases the prevalence of misalignments. These data are compatible with the notion that misalignment are caused by poor sensitivity to targets moving away from the infant and support the theory that some forms of strabismus could be related to failure in a system that is sensitive to the direction of motion.

The factor structure of the Edinburgh postnatal depression scale in a South African peri-urban settlement

The factor structure of the Edinburgh Postnatal Depression scale (EPDS) and similar instruments have received little attention in the literature. The researchers set out to investigate the construct validity and reliability of the EPDS amongst impoverished South African women. The EPDS was translated into isiXhosa (using Brislin's back translation method) and administered by trained interviewers to 147 women in Khayelitsha, South Africa. Responses were subjected to maximum likelihood confirmatory factor analysis. A single factor structure was found, consistent with the theory on which the EPDS was based. Internal consistency was satisfactory (a = 0.89).

New insights into probiotic mechanisms: a harvest from functional and metagenomic studies

There has been continued and expanding recognition of probiotic approaches for treating gastrointestinal and systemic disease, as well as increased acceptance of probiotic therapies by both the public and the medical community. A parallel development has been the increasing recognition of the diverse roles that the normal gut microbiota plays in the normal biology of the host. This advance has in turn has been fed by implementation of novel investigative technologies and conceptual paradigms focused on understanding the fundamental role of the microbiota and indeed all commensal bacteria, on known and previously unsuspected aspects of host physiology in health and disease. This review discusses current advances in the study of the host-microbiota interaction, especially as it relates to potential mechanisms of probiotics. It is hoped these new approaches will allow more rational selection and validation of probiotic usage in a variety of clinical conditions.
