For permissions, please e-mail: [email protected]: Paid employment has been shown to benefit childless women's health, while employed mothers experience poorer health, and more pronounced fatigue. This study measures the association between job characteristics and the health and well-being of employed mothers and the differential susceptibility to job characteristics between coupled and single-parent mothers. METHODS: We used data from the 5th Portuguese National Health Survey from 1649 employed women (aged 25-54) living with a child under 16. We modelled depression (assessed by the Personal Health Questionnaire-8) and self-reported health as a function of job characteristics, adding interaction terms to compare coupled and single-parent mothers, using logistic regressions. RESULTS: Working part-time was associated with depression (odds ratio (OR) = 3.39, 95% confidence interval (CI) = 3.31-3.48) and less-than-good health (OR = 1.28, 95%CI = 1.26-1.31), compared to working full time. Compared to high-skill jobs, the likelihood for depression among low-skill occupations was lower among coupled mothers (OR = 0.25, 95%CI = 0.24-0.26), and higher among single-parent mothers (OR = 1.75, 95%CI = 1.54-1.99). Unstable jobs were associated with depression among coupled mothers. CONCLUSIONS: Part-time jobs are detrimental for mothers' mental health, but high-skilled jobs are protective for single-parent mothers. Part-time and unstable jobs are linked to poorer self-reported health among coupled mothers. Results question the gendered arrangements that may face employed coupled mothers.publishersversionepub_ahead_of_prin

    Os bovinos da raça Sindi, originários do Paquistão, apresentam elevada rusticidade e alta tolerância ao calor. São animais de pequeno porte, pelagem avermelhada e altamente adaptados às condições adversas da região semiárida do Nordeste do Brasil. Diante da importância da brucelose e da tuberculose na saúde humana e animal, o Ministério da Agricultura, Pecuária e Abastecimento (MAPA) instituiu o Programa Nacional de Controle e Erradicação da Brucelose e Tuberculose (PNCEBT), visando diminuir o impacto negativo destas enfermidades nos rebanhos nacionais. Diante disso, o presente estudo teve como objetivo caracterizar sanitariamente os bovinos da raça Sindi do rebanho da Embrapa Semiárido, Petrolina, PE. Foram examinadas 109 amostras de soro sanguíneo dos bovinos pelo teste de soroaglutinação com Antígeno Acidificado Tamponado (AAT) para a detecção de anticorpos contra a Brucella abortus. Das 109 amostras avaliadas, todas apresentaram resultado negativo no teste de soroaglutinação rápida em placa. Realizou-se o teste intradérmico cervical comparado com as tuberculinas (PPD) bovina e aviária nos 109 animais e nenhum apresentou reação positiva para tuberculose. Diante dos resultados obtidos, concluiu-se que neste tipo de rebanho em que ocorre pouco ou nenhum transito de animais (entrada), o risco de ocorrência de brucelose e tuberculose é considerado pequeno.bitstream/item/17921/1/BPD78.pd

    Post-fire diversity and abundance in pine and eucalipt stands in Portugal: effects of biogeography, topography, forest type and post-fire management

    This study concerned the mid-term regeneration of the woody understory vegetation of pure and mixed stands of Pinus pinaster Ait. and Eucalyptus globulus Labill. in northern and central Portugal following wildfires in 2005 and 2006. Pine and eucalypt stands are the most widespread and most fire-prone forest types in Portugal. The main aim was to investigate the importance of biogeography, topography, forest type and post-fire management operations in explaining the patterns in shrub diversity (species richness) and abundance (cover). To this end, 284 study sites in four distinct biogeographic regions were sampled 5 to 7 years following the last wildfire. At each site, the presence and cover of individual shrub species were estimated using 4 sub-plot of approximately 10 m2 each. The entire data set was analyzed by means of GLM using a total of seven explanatory variables: biogeographic region, forest type, three types post-fire management operations (soil tillage, tree harvesting, and shrub clearance), and two topographic variables (slope angle and elevation). The GLM analysis was also done for the individual biogeographic regions. Biogeographic region and slope steepness were key factors explaining shrub species richness, albeit the role of slope angle was possibly linked to the intensity of past land use. Biogeographic region equally played a significant role in explaining the cover of all shrubs together as well as of the shrubs of Leguminosae and Cistaceae. All three types of post-fire management operations appeared to hamper the recovery of resprouters and Leguminosae, whereas just tree harvesting and shrub clearance (but not soil tillage) negatively affected the cover of seeder species. These impacts of post-fire management operations had a noticeable region-specific component, being more relevant in the less productive biogeographic regions. Also the role of forest type depended strongly on biogeographic region. It was only significant in the South Mediterranean region, where pine plantations had a higher total shrub cover as well as higher covers of seeders and Cistaceae. Possibly, however, this significant role of forest type could be due to the lower incidence of shrub clearance in the pine standsinfo:eu-repo/semantics/publishedVersio

    Prediction of Dynamic Plasmid Production by Recombinant Escherichia coli Fed-Batch Cultivations with a Generalized Regression Neural Network

    Get PDF
    A generalized regression neural network with external feedback was used to predict plasmid production in a fed-batch cultivation of recombinant Escherichia coli. The neural network was built out of the experimental data obtained on a few cultivations, of which the general strategy was based on an initial batch phase followed by an exponential feeding phase. The different cultivation conditions used resulted in significant differences in bacterial growth and plasmid production. The obtained model allows estimation of the experimental outputs (biomass, glucose, acetate and plasmid) based on the bioreactor starting conditions and the following on-line inputs: feeding rate, dissolved oxygen concentration and bioreactor stirring speed. Therefore, the proposed methodology presents a quick, simple and reliable way to perform on-line feedback prediction of the dynamic behaviour of the complex plasmid production process, based on simple on-line input data obtained directly from the bioreactor control unit and with few cultivation experiments for neural network learning

    A Target Enrichment Bait Set for Studying Relationships among Ostariophysan Fishes

    © 2020 by the American Society of Ichthyologists and Herpetologists. Target enrichment of conserved nuclear loci has helped reconstruct evolutionary relationships among a wide variety of species. While there are preexisting bait sets to enrich a few hundred loci across all fishes or a thousand loci from acanthomorph fishes, no bait set exists to enrich large numbers (\u3e1,000 loci) of ultraconserved nuclear loci from ostariophysans, the second largest actinopterygian superorder. In this study, we describe how we designed a bait set to enrich 2,708 ultraconserved nuclear loci from ostariophysan fishes by combining an existing genome assembly with low coverage sequence data collected from two ostariophysan lineages. We perform a series of enrichment experiments using this bait set across the ostariophysan tree of life, from the deepest splits among the major groups (\u3e150 Ma) to more recent divergence events that have occurred during the last 50 million years. Our results demonstrate that the bait set we designed is useful for addressing phylogenetic questions from the origin of crown ostariophysans to more recent divergence events, and our in silico results suggest that this bait set may be useful for addressing evolutionary questions in closely related groups of fishes, like Clupeiformes
