Images of Childhood in Mothers' Accounts of Contemporary Childrearing

This article examines how a sample of first-time mothers in the UK constitute childhood in general, and their own children in particular, in and through their talk about the mundane practices of child-care. The data analysed are drawn from a longitudinal qualitative interview study which followed a sample of mothers from late pregnancy until their babies were two years old. The analysis explores links between mothers’ representations of childhood and the actualities of their child-rearing practices. The extent to which both the representations of childhood and the practices of individual mothers are consistent or contradictory, and change or remain constant over time, is also examined.

Anticipatory Accounts

C. Wright Mills called for a truly sociological analysis of actors’ “motive talk,” which decouples the commonsense link between the reasons actors give for their actions and their mental state prior to those actions. Subsequent theoretical and empirical work has focused almost entirely on actors’ retrospective accounting for untoward conduct that has already taken place. The other aspect of Mills’s program, the reasons actors give for potentially untoward future conduct and in particular the empirical investigation of the link between the availability of an acceptable vocabulary of motives for anticipated conduct and the eventual enactment of that conduct, has been largely ignored. This article seeks to rehabilitate these lost dimensions using data from a longitudinal study of mothers’ infant feeding choices and practices. It examines how mothers account, in advance, for the possibility that they may eventually feed their babies in ways they consider suboptimal. Thirty of the thirty-six women interviewed indicated that they intended to breastfeed, emphasizing the benefits of this practice to their babies. However, seventeen of these women also anticipated that they might abandon breastfeeding and presented elaborate accounts of the motives that could lead them to do so. The findings support Mills’s claim that the availability of an acceptable vocabulary of motives for untoward conduct increases the probability that one will engage in such conduct. Mothers who had offered elaborate anticipatory accounts for abandoning breastfeeding were much more likely to do so than those who did not offer such accounts.

Portuguese National Accounts : a network approach

In recent years, the Portuguese economy has gone through a severe adjustment process, which aected almost every sector of the economy. Therefore, it is important to study how the structure of the economy changed during this period. To that end, using data on the annual output by industry and product from National Accounts, we developed a network of industries for the years 2010 and 2013. By comparing the Minimal Spanning Trees and a set of topological coecients for the years considered, we evaluate the structural evolution of the economy. In order to get a long term view, we extended the analysis to the period between 1995 and 2010. We found that the industries linked to trade activities maintained their centrality, although they decreased their importance over time. Together with construction activities, they were among the most severely aected industries.

Inter-industry analysis and monetary policy evaluations in the Korean flow of funds accounts

This study mainly aims to provide an inter-industry analysis through the subdivision of various industries in flow of funds (FOF) accounts. Combined with the Financial Statement Analysis data from 2004 and 2005, the Korean FOF accounts are reconstructed to form "from-whom-to-whom" basis FOF tables, which are composed of 115 institutional sectors and correspond to tables and techniques of input–output (I–O) analysis. First, power of dispersion indices are obtained by applying the I–O analysis method. Most service and IT industries, construction, and light industries in manufacturing are included in the first quadrant group, whereas heavy and chemical industries are placed in the fourth quadrant since their power indices in the asset-oriented system are comparatively smaller than those of other institutional sectors. Second, investments and savings, which are induced by the central bank, are calculated for monetary policy evaluations. Industries are bifurcated into two groups to compare their features. The first group refers to industries whose power of dispersion in the asset-oriented system is greater than 1, whereas the second group indicates that their index is less than 1. We found that the net induced investments (NII)–total liabilities ratios of the first group show levels half those of the second group since the former's induced savings are obviously greater than the latter.

Contrast and lustre:a model that accounts for eleven different forms of contrast discrimination in binocular vision

Our goal here is a more complete understanding of how information about luminance contrast is encoded and used by the binocular visual system. In two-interval forced-choice experiments we assessed observers' ability to discriminate changes in contrast that could be an increase or decrease of contrast in one or both eyes, or an increase in one eye coupled with a decrease in the other (termed IncDec). The base or pedestal contrasts were either in-phase or out-of-phase in the two eyes. The opposed changes in the IncDec condition did not cancel each other out, implying that along with binocular summation, information is also available from mechanisms that do not sum the two eyes' inputs. These might be monocular mechanisms. With a binocular pedestal, monocular increments of contrast were much easier to see than monocular decrements. These findings suggest that there are separate binocular (B) and monocular (L,R) channels, but only the largest of the three responses, max(L,B,R), is available to perception and decision. Results from contrast discrimination and contrast matching tasks were described very accurately by this model. Stimuli, data, and model responses can all be visualized in a common binocular contrast space, allowing a more direct comparison between models and data. Some results with out-of-phase pedestals were not accounted for by the max model of contrast coding, but were well explained by an extended model in which gratings of opposite polarity create the sensation of lustre. Observers can discriminate changes in lustre alongside changes in contrast.

Sim-xl: A Powerful And User-friendly Tool For Peptide Cross-linking Analysis.

Chemical cross-linking has emerged as a powerful approach for the structural characterization of proteins and protein complexes. However, the correct identification of covalently linked (cross-linked or XL) peptides analyzed by tandem mass spectrometry is still an open challenge. Here we present SIM-XL, a software tool that can analyze data generated through commonly used cross-linkers (e.g., BS3/DSS). Our software introduces a new paradigm for search-space reduction, which ultimately accounts for its increase in speed and sensitivity. Moreover, our search engine is the first to capitalize on reporter ions for selecting tandem mass spectra derived from cross-linked peptides. It also makes available a 2D interaction map and a spectrum-annotation tool unmatched by any of its kind. We show SIM-XL to be more sensitive and faster than a competing tool when analyzing a data set obtained from the human HSP90. The software is freely available for academic use at http://patternlabforproteomics.org/sim-xl. A video demonstrating the tool is available at http://patternlabforproteomics.org/sim-xl/video. SIM-XL is the first tool to support XL data in the mzIdentML format; all data are thus available from the ProteomeXchange consortium (identifier PXD001677).

Estudo teórico da interação existente entre a artemisinina e o heme

The purpose of this work is to study theoretically stereoelectronic aspects of the interaction between heme and artemisinin in the transitional heme-artemisinin complex. Through semi-empirical calculations using the PM3 method, the potential energy barrier of artemisinin rotation relative to heme in the heme-artemisinin complex was studied in vacuum and in the partially solvated state. The minimum heat of formation obtained for the complex with and without water molecules is -702.39 and -100.86 kcal mol-1, respectively, which corresponds to the dihedral angle C-Fe-O1-O2 of 43.93º and 51.90º around the iron-oxygen O1 bond, respectively. The water molecules bind to heme via 13 hydrogen bonds and O-H O and 6 C-H O interactions, which accounts for -67.23 kcal mol-1. It is observed that the inclusion of water molecules does not affect significantly the stability of the heme-artemisinin complex.

A valoração de traços de concordância dentro do DP

This paper argues in favor of a concord features valuing within the DP in terms of the Agree operation (Chomsky, 1999), with no recourse to any other mechanism. I show that Agree accounts for feature valuing both in the sentence level as well as in the DP, contrary to Chomsky's (1999) suggestion that concord in DP should involve some other checking mechanism.

Stress-induced neuroinflammation: mechanisms and new pharmacological targets

Stress is triggered by numerous unexpected environmental, social or pathological stimuli occurring during the life of animals, including humans, which determine changes in all of their systems. Although acute stress is essential for survival, chronic, long-lasting stress can be detrimental. In this review, we present data supporting the hypothesis that stress-related events are characterized by modifications of oxidative/nitrosative pathways in the brain in response to the activation of inflammatory mediators. Recent findings indicate a key role for nitric oxide (NO) and an excess of pro-oxidants in various brain areas as responsible for both neuronal functional impairment and structural damage. Similarly, cyclooxygenase-2 (COX-2), another known source of oxidants, may account for stress-induced brain damage. Interestingly, some of the COX-2-derived mediators, such as the prostaglandin 15d-PGJ2 and its peroxisome proliferator-activated nuclear receptor PPARγ, are activated in the brain in response to stress, constituting a possible endogenous anti-inflammatory mechanism of defense against excessive inflammation. The stress-induced activation of both biochemical pathways depends on the activation of the N-methyl-D-aspartate (NMDA) glutamate receptor and on the activation of the transcription factor nuclear factor kappa B (NFκB). In the case of inducible NO synthase (iNOS), release of the cytokine TNF-α also accounts for its expression. Different pharmacological strategies directed towards different sites in iNOS or COX-2 pathways have been shown to be neuroprotective in stress-induced brain damage: NMDA receptor blockers, inhibitors of TNF-α activation and release, inhibitors of NFκB, specific inhibitors of iNOS and COX-2 activities and PPARγ agonists. This article reviews recent contributions to this area addressing possible new pharmacological targets for the treatment of stress-induced neuropsychiatric disorders.

Experiência e linguagem como estratégias de resistência

Neste artigo visamos apontar, apoiadas em W. Benjamim e G. Agamben, a fragilização do registro da experiência e sua incidência na lógica do poder/violência. Analisamos, pretendendo desmistificar a eficácia dos discursos mortificadores da experiência, a figura do "mulçumano"; - nome que designava os mortos-vivos nos campos de concentração, conforme relato de Primo Levi e outros. Tal figura é emblemática do estado limite a que chegaram algumas pessoas e podem expressar o destino de alguns sujeitos na contemporaneidade. Pudemos identificar nessa posição tanto um movimento na direção da perda do laço identificatório com o semelhante, como uma forma de resistência à violência perpetrada pelo discurso social. Tal resistência consiste em operar uma mimese ao objeto resto, o que permite ao sujeito a manutenção da estrutura fantasmática. Indicamos que, apesar das estratégias do poder, o sujeito reinventa modos de se situar na relação ao Outro, nos quais se fazem importantes a presença e a palavra, incluindo aí a experiência psicanalítica.

Registros novos e adicionais de teleósteos marinhos na costa brasileira

São apresentadas novas informações sobre a distribuição geográfica de algumas espécies de peixes teleósteos que ocorrem na costa brasileira, incluindo duas espécies que nunca haviam sido registradas em nossas águas. Os serranídeos Pseudogramma gregoryi (assinalado da Flórida à Venezuela) e Plectranthias garrupellus (registrado da Carolina do Norte ao Caribe) foram encontrados, respectivamente, na costa do Ceará e na costa sudeste-sul do Brasil. São aqui mencionados e discutidos os dois primeiros registros do gênero Caristius (Caristiidae) no Brasil, bem como os primeiros registros na costa sudeste-sul do Brasil das espécies Enchelycore carychroa (Muraenidae), e Chilomycterus antillarum (Diodontidae), e da espécie Neobythites brasiliensis(Bythitidae) no nordeste do Brasil. É também assinalada a ocorrência mais setentrional do pargo Calamus mu (Sparidae), uma espécie até então circunscrita à região entre o Espírito Santo e São Paulo, e são discutidos os registros adicionais de Bascanichthys paulensis (Ophichthidae), Nezumia aequalis (Macrouridae), Antigonia combatia (Caproidae) e Notolycodes schmidti (Zoarcidae) na costa brasileira.

Participação comunitária em um programa de intervenção em área de proteção ambiental

Este artigo discute os conceitos de participação e empowerment em Promoção da Saúde e Desenvolvimento Sustentável, considerando as agendas de implementação local, Municípios/Cidades Saudáveis e Agenda 21, e a importância dos processos de avaliação nesse contexto, por meio da análise de uma intervenção em área de mananciais - o Programa Bairro Ecológico (PBE), desenvolvido em 51 bairros do município de São Bernardo do Campo, Estado de São Paulo, Brasil. O estudo teve por objetivo avaliar os processos de participação e empowerment da comunidade, a partir das ações desencadeadas pelo PBE. Foram aplicados questionários e realizados grupos focais com moradores de bairros que sofreram a intervenção. Também foram realizadas entrevistas individuais com gestores do programa e do poder judiciário. Os resultados indicaram que a participação na implementação do PBE favoreceu o empowerment individual e grupal, presente nas duas comunidades estudadas. As comunidades tornaram-se mais organizadas. Há indícios de que os processos de tomada de decisões são centralizados. Apesar disso, as comunidades entendem que sua participação no programa lhes traz muitas coisas boas. Houve um processo participativo no desenvolvimento do programa, ainda que alguns relatos apontem para o caráter obrigatório da participação. Deve-se destacar o impacto do envolvimento e fortalecimento das lideranças na implementação e sustentabilidade do programa. No que diz respeito a esta última, verificou-se que a sensibilização ambiental tem sido fator determinante para a execução e manutenção das ações ao longo do tempo.
