A partir de um enfoque antropológico, baseado na ideia de que a política não é um dado a priori e que precisa ser compreendida a partir das práticas e das formulações dos atores em contextos específicos, discutirei como a política é vivenciada pelos moradores do loteamento Boa Terra, situado em Guaratiba na Zona Oeste carioca, através de pesquisa qualitativa realizada entre os anos de 2008 e 2010. Além de acompanhar festas, atividades ordinárias e extraordinárias do centro comunitário local e campanhas eleitorais, visitei o loteamento em diferentes dias da semana com o objetivo de observar o cotidiano desses moradores. Embora tenha conversado e acompanhado as atividades dos moradores comuns, analisei com mais atenção as práticas desenvolvidas por aqueles que disputam o direito de falar em nome que, em geral, fazem (ou fizeram) parte de alguma associação local. Qual é o papel dessas associações? A que noções de bem público recorrem? Como se dá a relação entre os representantes locais e os moradores do loteamento? Que tipo de distinção existe entre eles? Como tais representantes se articulam no sentido de garantir as demandas de sua base? De que forma costuram relações no interior das agências estatais e com políticos em geral?

Effect of delayed icing on the quality of Penaeus monodon iced after three hours of harvest was studied in plastic and bamboo baskets. After harvest of three hours at ambient temperature (28°-32°C), ice was added to the shrimp at a ratio of 1:1 (shrimp:ice) and stored for 21 hours in both the baskets. Quality evaluation was carried out through visual assessment, biochemical analysis and microbial analysis for 24 hours. The organoleptic evaluation and scoring was done from the time of harvest treated as 0 hour and the average score was 10. At 9th hour after iced condition quality of shrimp was found reduced to the next stage (acceptable) with a score ranged from 8.4-6.5 in both baskets. This acceptable stage was observed throughout the experiment for bamboo basket whereas in the plastic basket the quality was reduced to a small extent with a score of 6.4 (moderately acceptable). Till the end point of the experiment the quality of shrimp was acceptable in respect to biochemical analysis. The microbial load was found log sub(10) 3.99±0.12 cfu/g to log sub(10) 4.33±0.21 cfu/g and log sub(10) 4.01 ±0.12 cfu/g to log sub(10) 4.83±0.19 cfu/g in the bamboo and plastic basket respectively. The importers or buyers suggests for immediate icing to maintain good quality but results of the present experiment suggest that the quality does not vary drastically for first three hours.

An investigation was carried out on the quality changes of Catla (Catla calla) stored immediately (0 h) in ice, after 6 hours in ice and at ambient temperature. The samples were examined for organoleptic and microbiological parameters in summer. Organoleptically, the acceptability of fish varied between 16-20 days in both the iced storage conditions and 12-13.5 hours at ambient temperature (28°C). When fish were organoleptically just acceptable on the 16th day of storage, bacterial load were 6.23 and 6.17 log10 cfu/g, respectively for 0 hour and after 6 hours iced fish. But on the 20th day of storage, when fish were just unacceptable SPC were 6.51 and 6.62 log10 cfu/g. In case of ambient temperature storage condition standard plate count was 8.36 log10 cfu/g on 13.5 hours, when fish were organoleptically just unacceptable. At the time of rejection for fish stored in ice (0 hour and after 6 hours) on 20th day, gram negative and gram positive values were 55.45%, 44.55% and 44.52%, 55.48% respectively. While fish were rejected after 13.5 hours at ambient temperature gram negative and gram positive bacteria were found as 43.02% and 56.98%. The differences in SPC, gram positive and gram negative bacteria between the storage times were statistically significant (p<0.05).

Estudo sobre a biologia, comportamento, intensidade de infestacao e quantificacao das perdas causadas pela broca-do-fruto no cupuacuzeiro para fornecer informacoes e, desse modo, aumentar os conhecimento de como melhorar o manejo dessa praga. O trabalho foi realizado em duas fases: a) campo - coleta semanal dos frutos caidos ao chao, registando o numero de furos na casca e o de larvas no interior do fruto; b) laboratorio - as larvas do ultimo instar foram colocadas dentro de garrafas de plastico de 2l contendo mistura de vermiculita esterilizada por 1h, a 160°C, na proporcao de 2:1. O substrato foi umedecido com agua destilada e as garrafas mantidas a 27°C±2°C, em umidade relativa de 80%±10% e fotoperiodo de 12h:12h, para o desenvolvimento pupal. A regiao mediana dos frutos foi a preferida para a perfuracao de saida das larvas. O numero de larvas foi crescente de fevereiro a abril, epoca de maior producao de frutos. A duracao media para transformacao da larva do ultimo instar para a emergencia dos adultos foi de 65,34 dias, a viabilidade foi de 81,62%, e a raza sexual, 1:1. a intensidade de infestacao foi de 85,0% a 93,33%, com altas perdas na producao.

Previous authors have suggested a higher likelihood for industry-sponsored (IS) studies to have positive outcomes than non-IS studies, though the influence of publication bias was believed to be a likely confounder. We attempted to control for the latter using a prepublication database to compare the primary outcome of recent trials based on sponsorship. We used the "advanced search" feature in the clinicaltrials.gov website to identify recently completed phase III studies involving the implementation of a pharmaceutical agent or device for which primary data were available. Studies were categorized as either National Institutes of Health (NIH) sponsored or IS. Results were labeled "favorable" if the results favored the intervention under investigation or "unfavorable" if the intervention fared worse than standard medical treatment. We also performed an independent literature search to identify the cardiovascular trials as a case example and again categorized them into IS versus NIH sponsored. A total of 226 studies sponsored by NIH were found. When these were compared with the latest 226 IS studies, it was found that IS studies were almost 4 times more likely to report a positive outcome (odds ratio [OR] 3.90, 95% confidence interval [CI] 2.6087 to 5.9680, p <0.0001). As a case example of a specialty, we also identified 25 NIH-sponsored and 215 IS cardiovascular trials, with most focusing on hypertension therapy (31.6%) and anticoagulation (17.9%). IS studies were 7 times more likely to report favorable outcomes (OR 7.54, 95% CI 2.19 to 25.94, p = 0.0014). They were also considerably less likely to report unfavorable outcomes (OR 0.11, 95% CI 0.04 to 0.26, p <0.0001). In conclusion, the outcomes of large clinical studies especially cardiovascular differ considerably on the basis of their funding source, and publication bias appears to have limited influence on these findings.

Conflicts of interests have long been recognized as potential sources of influence in the conduct and reporting of clinical trials. This controversy was again rekindled after the publication of the latest statin guidelines and a series of studies regarding competing interests in leading medical journals. We investigate the association between declared author conflicts and the outcomes of large cardiovascular trials. We searched the Medline (PubMed) database to identify "phase 2" and "phase 3" clinical trials using the search term "cardiovascular" over the past decade using "10 years" as the filter. We perceived the competing interest as present regardless of the nature such as consulting fees, honoraria, travel imbursements, stock holding, and employment. Of the 699 titles retrieved, 114 studies met the inclusion criteria. Nearly 80% of studies had at least a single author with competing interests. The 114 studies had a total of 1,433 investigators, of which 725 had declared conflicts of interests (50.6%). A total of 66 studies (58%) had half or >50 percent of investigators who had some conflicts of interests. Of these studies, 54 studies had favorable outcomes and only 12 had unfavorable outcomes (p <0.001). Among the type of competing interests, consulting or personal fees was the most common present in 58 investigators (51%). This was followed by research grants present in 55 the researchers (48%). Among 25 (22%) studies, at least one investigator reported stakes in the industry, of which only 2 studies had unfavorable outcomes for the intervention being investigated. Just 1 of the 25 clinical trials with a sample size of >1,000 had no investigators with competing interests. In conclusion, authors conflicts are associated with favorable outcomes in cardiovascular outcome trials.

Las evaluaciones genéticas para caracteres funcionales requieren metodologías como el análisis de supervivencia (SA), que contemplen registros pertenecientes a hembras que no han presentado el evento de interes (descarte o prenez) al momento de la evaluacion. Así, los objetivos de esta tesis fueron: 1) analizar los factores que afectan el riesgo de descarte en vida productiva (VP), y de concepción en días abiertos (DA) e intervalo primer-último servicio (IP), 2) estimar parámetros genéticos de dispersión para los caracteres evaluados. Se emplearon 44652 registros de lactancia de 15706 vacas Holstein Colombiano, ajustando un modelo animal frágil Weibull para VP, con el número de partos (NP), producción de leche (PL) y edad al primer parto (EPP) como efectos fijos. En el caso de DA e IPU se emplearon 14789 servicios de 6205 vacas, ajustando un modelo de datos agrupados con efectos fijos de NP, EPP y número de servicios (SC). En todos los casos se incluyeron efectos aleatorios de animal y de hato. Tanto PL como NP tuvieron gran influencia en la VP, al igual que NP en DA e IPU. Se estimaron valores de h2 de 0,104, 0,086 y 0,1013 para VP, DA, e IPU, respectivamente, asi como correlaciones genéticas simples (rs) entre el nivel de PL con VP y DA de ƒ{0,03 y 0,47, respectivamente. Teniendo en cuenta tanto los valores de cría expresados como riesgo relativo, asi como la magnitud de rs, un aumento en PL conllevaría a disminución en el riesgo de descarte y aumento en el riesgo de concepción, dando lugar a aumentos en la VP y reducción en DA. Las h2s estimadas sugieren la existencia de variabilidad genetica para VP, DA e IPU en Holstein Colombiano, sirviendo de sustento para la implementación de evaluaciones genética de la raza, aprovechando las ventajas de metodologías como SA.

El presente artículo tiene como objetivo presentar los resultados de la investigación realizada con alumnos jóvenes y adultos en una escuela pública en la ciudad de Uberlandia/MG (Brasil), tratando de reflexionar y aprender a percibir la presencia de conocimientos africanos en matemáticas por manifestaciones de tradiciones afro-brasileñas, además de identificar que los estudiantes contemplando la cuestión de la raza, apodos y la imagen que tienen de las matemáticas y de las tradiciones afro-brasileñas, con miras a desarrollar una educación enraizada en los fundamentos de nociones, que busca reforzar la producción de conocimientos matemáticos a otros grupos sociales para una matemática crítica e incluyente. La encuesta también trató de contribuir al desarrollo de acciones educativas basadas en la ley brasileña 10.639/03. La enseñanza de las matemáticas, teniendo debidamente en cuenta los cultivos afro brasileños también tienen mucho que contribuir a la comprensión del mundo como una posibilidad para desarrollar valores y ampliar conceptos.

Atualmente, a escola vive sempre procurando acompanhar as constantes transformações do mundo “globalizado”, e isso se transforma numa luta, às vezes desigual, pela conquista do universo dos estudantes tão bombardeado de novidades audiovisuais e eletrônicas. Neste trabalho, mostra‐se como a partir do estudo do meio, foi possível despertar o interesse de estudantes brasileiros do ensino médio pela Geometria presente na construção da maloca de indígenas Uitoto da Amazônia colombiana. Mostra também, que além dos meios tecnológicos disponíveis, o professor de matemática pode utilizar os recursos existentes na comunidade ou na própria escola como objeto de ensino atrativo, pois tudo depende da forma como este objeto irá ser usado.
