La etapa formativa de la Secretaría de Trabajo y Previsión (1943-1946) : primeros pasos organizativos y figuras relevantes

A través del análisis de distintas fuentes estatales, biografías y publicaciones especializadas, entre otras, este artículo reconstruye los primeros pasos en el armado del área de Trabajo y Previsión durante el gobierno militar de 1943-1946, momento en el que tras varias décadas de actuación del viejo Departamento Nacional de Trabajo, se resolvió la jerarquización de los asuntos del trabajo en el organigrama estatal. En este lapso, se estableció la base de la organización interna de la nueva Secretaría de Trabajo y Previsión, de la mano de los aportes de varios personajes que procuramos recuperar aquí y que han quedado eclipsados por el peso de los nombres del propio Juan Perón y de sus colaboradores más conocidos y cercanos.

Percepção e orientação de condutas de conselheiros tutelares sobre práticas sexuais de menores de 18 anos

A abertura política do Brasil à democracia promoveu uma série de mudanças legislativas e de organização do Estado. Na área da infância e adolescência, após a promulgação do Estatuto da Criança e do Adolescente (ECA), foram criados conselhos de nível federal, estadual e municipal, com o objetivo de promover e defender os direitos dessa população específica. Também foram formados os Conselhos Tutelares compostos por membros da sociedade civil, diretamente eleitos pela população, com a função de informar e promover esses direitos localmente. Utilizando a metodologia qualitativa-quantitativa do Discurso do Sujeito Coletivo, a pesquisa analisou a percepção e opinião dos conselheiros tutelares a respeito de situações que envolvem a prática sexual voluntária heterossexual e homossexual de adolescentes da faixa etária de 12 a 17 anos. Os dados foram colhidos com o uso de questionários semiestruturados para autopreenchimento, apresentados em visita técnica aos membros dos 44 Conselhos Tutelares do município de São Paulo. Além do perfil social e familiar, foram coletadas opiniões dos conselheiros quanto à autonomia dos adolescentes e suas noções de desrespeito legal, além de sugestões de orientação de condutas frente a três casos hipotéticos de prática sexual realizada por adolescentes. Responderam à pesquisa 80 (36,4 por cento ) conselheiros de um total de 220, de 29 (65,9 por cento ) dos 44 Conselhos Tutelares da cidade. Observou-se que apresentaram tendência a reproduzir os modelos tradicionais negativos da sociedade brasileira no julgamento da prática sexual de adolescentes, avaliando sua ocorrência pela ótica moral e de opinião de familiares e outros adultos. Mais da metade não associa tais práticas a impactos específicos sobre a saúde e os direitos sexuais e reprodutivos dos adolescentes, nem realiza encaminhamentos para sua promoção. Adotam noções desiguais de gênero do senso comum, que remetem à preocupação com a imagem e impactos da publicização da sexualidade de meninas, não fazendo o mesmo para adolescentes meninos e veem as práticas homoafetivas sob a ótica da violência e sedução, associando-as à necessidade de orientação psicológica e problemas de saúde mental. Considera-se que conselheiros tutelares estão pouco preparados para lidar com a sexualidade de adolescentes e normalmente treinados para avaliá-la tal qual a violência sexual que acomete crianças. Como possuem status local de legitimidade, são procurados e tem poder de averiguação e encaminhamento público de ocorrências, terminando por, muitas vezes, desrespeitar os direitos humanos de adolescentes quanto à expressão e vivência da sexualidade e da prática sexual saudável. Considera-se fundamental discutir o papel dos Conselhos Tutelares frente aos direitos de adolescentes, de forma que ao contrário do proposto na democratização do país, não se configurem como mais um instrumentos de exercício de poder para perpetuar desigualdades sociais. Na área da sexualidade, a defesa dos direitos de adolescentes passa pelo respeito a sua sexualidade, acesso à informação, à garantia de serviços públicos que efetivamente os atendam para proporcionar exames, contracepção, prevenção de doenças sexualmente transmissíveis, etc., com respeito a sua cidadania, especificidades, necessidades, autonomia e dignidade pessoal, promovendo-os e defendendo-os frente a famílias, comunidade, a toda a sociedade e ao próprio poder público.

Solid-state Marx based two-switch voltage modulator for the On-Line Isotope Mass Separator accelerator at the European Organization for Nuclear Research

A new circuit topology is proposed to replace the actual pulse transformer and thyratron based resonant modulator that supplies the 60 kV target potential for the ion acceleration of the On-Line Isotope Mass Separator accelerator, the stability of which is critical for the mass resolution downstream separator, at the European Organization for Nuclear Research. The improved modulator uses two solid-state switches working together, each one based on the Marx generator concept, operating as series and parallel switches, reducing the stress on the series stacked semiconductors, and also as auxiliary pulse generator in order to fulfill the target requirements. Preliminary results of a 10 kV prototype, using 1200 V insulated gate bipolar transistors and capacitors in the solid-state Marx circuits, ten stages each, with an electrical equivalent circuit of the target, are presented, demonstrating both the improved voltage stability and pulse flexibility potential wanted for this new modulator.

Survey of Staff and Organization of Private Secondary School Libraries in Ondo West Local Government Area of Ondo State

The teacher-librarian and organization of private secondary school libraries in Ondo West Local Government Area of Ondo State was the focus of the study. A structured questionnaire was the instrument used for data collection. Copies of questionnaires were administered to staff of six school libraries surveyed. The study revealed that none of the staff were professionally qualified, which resulted in poor and haphazard organization of the resources in all the schools surveyed. Recommendations were made to improve library services, including pr

Low-Resolution Molecular Models Reveal the Oligomeric State of the PPAR and the Conformational Organization of Its Domains in Solution

The peroxisome proliferator-activated receptors (PPARs) regulate genes involved in lipid and carbohydrate metabolism, and are targets of drugs approved for human use. Whereas the crystallographic structure of the complex of full length PPAR gamma and RXR alpha is known, structural alterations induced by heterodimer formation and DNA contacts are not well understood. Herein, we report a small-angle X-ray scattering analysis of the oligomeric state of hPPAR gamma alone and in the presence of retinoid X receptor (RXR). The results reveal that, in contrast with other studied nuclear receptors, which predominantly form dimers in solution, hPPAR gamma remains in the monomeric form by itself but forms heterodimers with hRXR alpha. The low-resolution models of hPPAR gamma/RXR alpha complexes predict significant changes in opening angle between heterodimerization partners (LBD) and extended and asymmetric shape of the dimer (LBD-DBD) as compared with X-ray structure of the full-length receptor bound to DNA. These differences between our SAXS models and the high-resolution crystallographic structure might suggest that there are different conformations of functional heterodimer complex in solution. Accordingly, hydrogen/deuterium exchange experiments reveal that the heterodimer binding to DNA promotes more compact and less solvent-accessible conformation of the receptor complex.

Structure, organization and dynamics of functional supramolecular materials studied by solid-state NMR

Functional materials have great importance due to their many important applications. The characterization of supramolecular architectures which are held together by non-covalent interactions is of most importance to understand their properties. Solid-state NMR methods have recently been proven to be able to unravel such structure-property relations with the help of fast magic-angle spinning and advanced pulse sequences. The aim of the current work is to understand the structure and dynamics of functional supramolecular materials which are potentially important for fuel-cell (proton conducting membrane materials) and solar-cell or plastic-electronic applications (photo-reactive aromatic materials). In particular, hydrogen-bonding networks, local proton mobility, molecular packing arrangements, and local dynamics will be studied by the use of advanced solid-state NMR methods. The first class of materials studied in this work is proton conducting polymers which also form hydrogen-bonding network. Different materials, which are prepared for high 1H conduction by different approaches are studied: PAA-P4VP, PVPA-ABPBI, Tz5Si, and Triazole-functional systems. The materials are examples of the following major groups; - Homopolymers with specific functional groups (Triazole functional polysiloxanes). - Acid-base polymer blends approach (PAA-P4VP, PVPA-ABPBI). - Acid-base copolymer approach (Triazole-PVPA). - Acid doped polymers (Triazole functional polymer doped with H3PO4). Perylenebisimide (PBI) derivatives, a second type of important functional supramolecular materials with potent applications in plastic electronics, were also investigated by means of solid-state NMR. The preparation of conducting nanoscopic fibers based on the self-assembling functional units is an appealing aim as they may be incorporated in molecular electronic devices. In this category, perylene derivatives have attracted great attention due to their high charge carrier mobility. A detailed knowledge about their supramolecular structure and molecular dynamics is crucial for the understanding of their electronic properties. The aim is to understand the structure, dynamics and packing arrangements which lead to high electron conductivity in PBI derivatives.

Multiple quantum solid-state NMR indicates a parallel, not antiparallel, organization of β-sheets in Alzheimer's β-amyloid fibrils

Senile plaques associated with Alzheimer's disease contain deposits of fibrils formed by 39- to 43-residue β-amyloid peptides with possible neurotoxic effects. X-ray diffraction measurements on oriented fibril bundles have indicated an extended β-sheet structure for Alzheimer's β-amyloid fibrils and other amyloid fibrils, but the supramolecular organization of the β-sheets and other structural details are not well established because of the intrinsically noncrystalline, insoluble nature of amyloid fibrils. Here we report solid-state NMR measurements, using a multiple quantum (MQ) 13C NMR technique, that probe the β-sheet organization in fibrils formed by the full-length, 40-residue β-amyloid peptide (Aβ1–40). Although an antiparallel β-sheet organization often is assumed and is invoked in recent structural models for full-length β-amyloid fibrils, the MQNMR data indicate an in-register, parallel organization. This work provides site-specific, atomic-level structural constraints on full-length β-amyloid fibrils and applies MQNMR to a significant problem in structural biology.
