A formação continuada desempenha um papel fundamental nas discussões referentes às mudanças curriculares e pedagógicas do ensino médio integrado, buscando assegurar qualidade do ensino e promovendo a integração entre o ensino técnico e a educação geral. Este artigo analisa a formação continuada no Instituto Federal Catarinense -Campus Araquari, abordando os desafios enfrentados no contexto institucional e a atuação da equipe pedagógica do Núcleo Pedagógico (NuPe) neste processo ressaltando a importância da colaboração e do diálogo na comunidade acadêmica, particularmente nos Colegiados de Curso. A pesquisa, de abordagem qualitativa, apresenta um estudo de caso, por meio de levantamento e análise documental, que descreve a experiência da equipe pedagógica ao planejar e desenvolver ações de formação continuada de docentes e técnicos-administrativos, dentro dos colegiados de curso, desde 2014. A pesquisa revelou que os colegiados de curso desempenham um papel relevante como espaços de formação continuada para superar os desafios e alcançar os objetivos educacionais.

Le présent document décrit l’utilisation des modèles linéaires généralisés (GLM) pour la création d’indices d’abondance du stock de Bobo(Pseudotolithus Elongatus) en Guinée et Guinée Bissau. Les modèles GLM permettent de prendre en compte les variations de protocole d’échantillonnage dans l’observation des captures des flottilles de pêche concernées. Les données utilisées proviennent, d’une part des campagnes scientifique démersales réalisées dans les deux pays depuis les années 1980, et d’autre part des données de captures et d’effort des pêcheries artisanales maritimes et industrielles disponibles pour les deux pays.

Abstract Biomass of the schooling fish Rastrineobola argentea (dagaa) is presently estimated in Lake Victoria by acoustic survey following the simple “rule” that dagaa is the source of most echo energy returned from the top third of the water column. Dagaa have, however, been caught in the bottom two-thirds, and other species occur towards the surface: a more robust discrimination technique is required. We explored the utility of a school-based random forest (RF) classifier applied to 120 kHz data from a lake-wide survey. Dagaa schools were first identified manually using expert opinion informed by fishing. These schools contained a lake-wide biomass of 0.68 million tonnes (MT). Only 43.4% of identified dagaa schools occurred in the top third of the water column, and 37.3% of all schools in the bottom two-thirds were classified as dagaa. School metrics (e.g. length, echo energy) for 49 081 manually classified dagaa and non-dagaa schools were used to build an RF school classifier. The best RF model had a classification test accuracy of 85.4%, driven largely by school length, and yielded a biomass of 0.71 MT, only c. 4% different from the manual estimate. The RF classifier offers an efficient method to generate a consistent dagaa biomass time series.

BackgroundFew data on the virological determinants of hepatitis B virus (HBV) infection are available from southern Africa.MethodsWe enrolled consecutive HIV-infected adult patients initiating antiretroviral therapy (ART) at two urban clinics in Zambia and four rural clinics in Northern Mozambique between May 2013 and August 2014. HBsAg screening was performed using the Determine® rapid test. Quantitative real-time PCR and HBV sequencing were performed in HBsAg-positive patients. Risk factors for HBV infection were evaluated using Chi-square and Mann-Whitney tests and associations between baseline characteristics and high level HBV replication explored in multivariable logistic regression.ResultsSeventy-eight of 1,032 participants in Mozambique (7.6%, 95% confidence interval [CI]: 6.1–9.3) and 90 of 797 in Zambia (11.3%, 95% CI: 9.3–13.4) were HBsAg-positive. HBsAg-positive individuals were less likely to be female compared to HBsAg-negative ones (52.3% vs. 66.1%, p<0.001). Among 156 (92.9%) HBsAg-positive patients with an available measurement, median HBV viral load was 13,645 IU/mL (interquartile range: 192–8,617,488 IU/mL) and 77 (49.4%) had high values (>20,000 UI/mL). HBsAg-positive individuals had higher levels of ALT and AST compared to HBsAg-negative ones (both p<0.001). In multivariable analyses, male sex (adjusted odds ratio: 2.59, 95% CI: 1.22–5.53) and CD4 cell count below 200/μl (2.58, 1.20–5.54) were associated with high HBV DNA. HBV genotypes A1 (58.8%) and E (38.2%) were most prevalent. Four patients had probable resistance to lamivudine and/or entecavir.ConclusionOne half of HBsAg-positive patients demonstrated high HBV viremia, supporting the early initiation of tenofovir-containing ART in HIV/HBV-coinfected adults.

Neste traballo descríbese o sector mitilicultor de Puerto Almanza, Arxentina, identificando e analizando os distintos compoñentes da cadea produtiva no ano 2011. A mitilicultura é unha acti-vidade produtiva complementaria para o desenvolvemento socioeconómico en Puerto Almanza, a cal se atopa nunha etapa de desenvolvemento tanto no que respecta ao sector artesanal como ao sec-tor industrial. Observáronse posibilidades para o crecemento e desenvolvemento endóxeno da acti-vidade, aínda que se detectaron problemas na súa cadea produtiva. No necesario proceso de conso-lidación cara á sostibilidade da miticultura na zona deben intervir os principais actores da actividade, destacando o rol fundamental reservado ao Estado. A recomendación para o longo prazo é asegurar o manexo apropiado desta zona de produción de moluscos nun marco de desenvolvemento sostible e participativo.&#x0D; &#x0D;

Abstract A time series of aerial censuses of Cape fur seal colonies, spanning four decades (1972–2009) and three countries (South Africa, Namibia, and Angola), was analyzed to assess spatio‐temporal changes in population numbers. A weighted quantile regression approach was used to estimate trends in pup counts that were used as proxies for numbers of older animals at breeding colonies. There was a 74% increase in the number of breeding colonies over the study period, from 23 in 1973 to 40 in 2009. There was also a significant northward shift in the distribution of the breeding population. This was largely attributable to events in the northern part of the population's range coinciding with Namibia, where seal numbers declined at most colonies in the south of Namibia while several new breeding colonies developed in the northern part of Namibia and one in southern Angola. Despite range expansion and the development of new colonies, the overall size of the population in 2009 was similar to that of the early 1990s, according to the pup count models. Potential mechanisms for the observed changes, and their management implications, are discussed.
