    RESUMO: Este estudo visa apontar dados e reflexões sobre as representações sociais acerca das atividades de leitura dos alunos do Ensino Médio de uma escola pública de Várzea Grande – MT. E, mais especificamente, investigar os sentidos de leitura produzidos. Tivemos como base teórico-metodológica discussões das representações sociais como eixo para compreensão dos dados no tocante às análises de objetos de estudo concernentes ao contexto educacional. Utilizamos a técnica de Associação Livre de Palavras e o processamento do corpus ocorreu por meio do software EVOC na coleta de dados. Em estudo, também, estiveram reflexões sobre leitura Bakhtin (1952-53/1979, 2003), (ROJO, 2004, 2009) e as Orientações Curriculares Nacionais para o Ensino Médio (OCEM, 2006). Nesse sentido, compreendemos a leitura numa visão responsiva e ativa. A observação dos dados enfatizou que o ato de ler advindo do contexto escolar, evocado para o tema leitura, está centralmente sintetizado pela imagem do livro, este, também, está vinculado à ideia de aprendizagem e conhecimento. ABSTRACT: This study aims to point data and reflections of the social representations about the reading activities of high school students from a public school in Várzea Grande - MT. And more specifically, investigate the meaning of the produced reading. We had as theoretical and methodological base discussions of social representations as an axis to understand the data with regard to the analysis of study objects related to the educational context. We use the technique of Free Association of Words and the corpus processing occurred through the EVOC software in data collection. In study, also, were reflections on Bakhtin reading (1952-53 / 1979, 2003), (ROJO, 2004, 2009) and the National Curriculum Guidelines for High School (OCEM, 2006).In this sense, we understand reading in a responsive and active vision. The data observation emphasized that the act of reading coming from the school context, referred to the theme of reading, it is centrally synthesized by the picture of the book, this one is linked to the idea of learning and knowledge

    Os inventários florestais para múltiplos produtos requerem estimativas exatas do diâmetro, comprimento e volume de cada produto. As equações de afilamento têm sido usadas para descrever precisamente a forma da árvore uma vez que estas funções fornecem estimativas de diâmetro a qualquer altura ou de altura em qualquer diâmetro. Este trabalho aplica um modelo de programação por metas para estimar os parâmetros de duas equações de afilamento para descrever a forma do tronco de árvores individuais. O modelo de programação por metas gera parâmetros que minimizam a soma dos desvios absolutos (MOTAD). Esses parâmetros gerados pelo método MOTAD foram comparados aos parâmetros gerados pelo método dos mínimos quadrados ordinários (OLS). A análise se baseou em dados de cubagem de 178 árvores obtidas em plantios clonais de eucaliptos conduzidos na região sul da Bahia. Os valores dos parâmetros estimados por ambos os métodos de ajuste para as duas funções de afilamento mostraram-se muito semelhantes. Não houve diferença significativa entre os indicadores usados para avaliar a qualidade dos parâmetros estimados pelos dois métodos de ajuste. Os métodos OLS e MOTAD mostraram-se igualmente precisos na estimação de diâmetros e volumes com casca e sem casca.Multiple product inventories of forests require accurate estimates of the diameter, length and volume of each product. Taper functions have been used to precisely describe tree form, once they provide estimates for the diameter at any height or the height at any diameter. This study applied a goal programming technique to estimate the parameters of two taper functions to describe individual tree forms. The goal programming formulation generates parameters that minimize total absolute deviations (MOTAD). These parameters generated by the MOTAD method were compared to those of ordinary least squares (OLS) method. The analysis used a set of 178 trees cut from cloned eucalyptus plantations in the Southern part of the state of Bahia, Brazil. The values of the estimated parameters for the two taper functions resulted very similar when the two methods were compared. There was no significant difference between the two fitting methods according to the statistics used to evaluate the quality of the generated estimates. OLS and MOTAD resulted equally precise in the estimation of diameters and volumes outside and inside bark

    This study analyzes how foreign multinational enterprises respond to uncertainty in their cross-border acquisitions in emerging economies and,specifically in Brazil, given the institutional differences that separate the home and host countries. We analyze how institutional distance impactsmultinational enterprises strategy in taking a partial or full ownership stake in their Brazilian acquisitions. We propose that the equity stake is astrategic response to the uncertainty of operating in institutionally distant countries. In an study based on secondary data of 736 acquisitions between2008 and 2012, we tested statistically the relation between nine dimensions of institutional distance and the equity stake acquired. Results showdifferentiated effects albeit with significant evidence that greater geographic distance lead multinational enterprises to take a partial equity stake,while financial and cultural distance leads to a full acquisition. This study has two contributions: reinforces the understanding of the institutionalchallenges of entering emerging economies, and puts forth how firms’ strategies may incorporate structural solutions that minimize risks andinvestments when facing institutional uncertainties.info:eu-repo/semantics/publishedVersio

    The zooxanthellate scleractinian coral Oulastrea crispata (Lamarck, 1816), an overlooked newcomer in the Mediterranean Sea?

    Get PDF
    The zooxanthellate scleractinian coral Oulastrea crispata, a widely distributed species across central Indo-Pacific nearshore marine habitats, has been first reported from the Mediterranean Sea (Corsica) in 2014. Here we report on two new sites for this species in the NW Mediterranean Sea and provide a general description of external morphological characters of the colonies and a detailed account of the cnidom to help future identifications. Living specimens may appear virtually identical to small colonies (~5 cm) of the Mediterranean zooxanthellate scleractinian Cladocora caespitosa. While this species shows long, ramified, independent corallites, with cylindrical calices, O. crispata has enlarged, cup-like calices, which can be joined by the coenosteum. It also shows clear differences among several groups of nematocysts, principally the presence in the filaments of large penicilli (p-mastigophore) of one type, which are absent in C. caespitosa. Identifications based on underwater observations or even the analysis of photographs may easily lead to misleading identifications. We hypothesize that O. crispata may have gone unnoticed because of misidentifications as C. caespitosa. More detailed research is needed to get reliable maps of the actual distribution of this apparently non-indigenous species in the Mediterranean Sea

    Technically oriented companies have different formats, from government, cooperatives and even farmers themselves. In this sense, agricultural censuses play an important role in the context of mapping establishments that receive or do not receive some type of technical guidance. Thus, this work aims to analyze the configurations of technical guidance comparatively from the 2006 and 2017 censuses in the state of Rio Grande do Sul. The analyzes are carried out through descriptive statistics. The mesoregion with the most agricultural establishments receiving some type of technical guidance is the Northwest (23.13%), which has the characteristic of being one of those with the most municipalities, which are mostly family-owned. The mesoregion that has the least is the Southwest (2.15%), which has larger agricultural establishments and livestock and grain production systems. To a large extent, the productive dynamics are linked to the majority type of technical guidance received. Coastal regions are largely unattended, and in some municipalities, it began to have a presence in the 2017 census of technical assistance from farmers themselves. The technical assistance of governmental origin had a decrease in several regions, on the other hand, own assistance and of cooperatives gained space. Although there is a pluralism of technical orientation, they do not necessarily coexist, being dispersed according to territorial dynamics, and even so, more than 50% of establishments in the state do not receive any type of technical orientation.As empresas de orientação técnica apresentam diferentes formatos, desde as governamentais, das cooperativas e até mesmo dos próprios agricultores. Os censos agropecuários neste sentido desempenham um importante papel no contexto de mapear os estabelecimentos que recebem ou não algum tipo de orientação técnica. Este trabalho tem como objetivo analisar comparativamente as configurações de orientação técnica no estado do Rio Grande do Sul entre os censos de 2006 e 2017, utilizando como recorte as mesorregiões geográficas. A mesorregião que mais apresenta estabelecimentos agropecuários recebendo algum tipo de orientação técnica é a Noroeste (23,13%), a qual apresenta característica de ser uma das que mais possui municípios, os quais são majoritariamente familiares. A mesorregião que menos possui é a Sudoeste (2,15%), sendo a que dispõe de estabelecimentos agropecuários maiores e sistema produtivos de pecuária e grãos. Em larga medida, as dinâmicas produtivas estão interligadas ao tipo majoritário de orientação técnica recebida. Regiões litorâneas em larga medida estão desassistidas, sendo que em alguns municípios começou a ter presença no censo de 2017 de assistência técnica dos próprios agricultores. A assistência técnica de origem governamental teve uma diminuição em diversas regiões, em contrapartida, assistência própria e de cooperativas ganhou espaço. Apesar de haver um pluralismo de orientação técnica, elas não necessariamente coexistem, estando pulverizadas conforme as dinâmicas territoriais e mesmo assim, mais de 50% dos estabelecimentos do estado não recebem nenhum tipo de orientação técnica

Se evalúa cómo la distancia institucional influye en la estrategia de las multinacionales extranjeras en la toma de propiedad parcial o total del capital en las adquisiciones en Brasil. Se propone que el grado de propiedad es una respuesta estratégica frente a la incertidumbre de operar en mercados institucionalmente más lejanos. En un estudio con base en datos secundarios de 736 adquisiciones realizadas entre 2008 y 2012, se ha puesto estadísticamente a prueba la relación entre nueve dimensiones de distancia institucional y el nivel de propiedad adquirido. Los resultados muestran efectos diferenciados, pero con evidencia significativa de que mayores distancias geográficas conducen a la toma de propiedad parcial, mientras que una mayor distancia financiera y cultural conduce a la toma de propiedad total.

    From February 1992 to March 1997, 245 European mouflon (Ovis orientalis musimon) from Sierras de Cazorla, Segura y Las Villas Natural Park (southern Spain) were surveyed for oestrid larvae in order to estimate prevalence and mean intensity of parasitism by Oestrus ovis. Over 46 percent of the animals surveyed were infected, with a mean intensity of 9.6 larvae/host parasitized. No significant differences in prevalence rates between host sexes were observed, but older mouflons were infected with more larvae than younger ones.Peer Reviewe

    Desigualdades por sexo e por raça e o direito aos transplantes de órgãos no Brasil

    Get PDF
    O presente texto trata do perfi l dos transplantados e do problema das desigualdades no acesso aos transplantes de órgãos no Sistema Nacional de Transplantes (SNT) do Sistema Único de Saúde (SUS). A equidade nos procedimentos relacionados com transplantes de órgãos no Brasil recebe garantias constitucionais. Um recorte por gênero indica que o Brasil tem população com maioria de mulheres. Sob o ponto de vista étnico, pretos e pardos são a maioria da população. As necessidades de transplantes não diferem muito entre esses diferentes grupos populacionais. A despeito disso, contata-se que a maioria dos transplantes de órgãos, no Brasil, são feitos em homens e em brancos. Existem inúmeras causas para essas desigualdades

    Cultural Differences between University Students in Online Learning Quality and Psychological Profile during COVID-19

    During the COVID-19 pandemic, educational systems had to adapt to the social and health situation immediately. This led to the appearance of the asynchronous teaching model. Throughout the pandemic at an educational level, we can distinguish three phases, eminently online, hybrid, and face-to-face. However, the perception of educational quality in these three educational moments, considering the psychometric profile and cultural differences comparing Ibero-American countries, has not been studied. The study aims to analyze the psychological profile, and perception of quality in the teaching–learning processes at the university stage, during the three processes of educational transition during COVID-19: online, hybrid, and face-to-face. Thus, 1093 university students from Ibero-American countries were studied. Through a questionnaire, demographic, academic, and psychological variables were analyzed during three phases of the pandemic. Data suggest that Latin American students had higher levels of trait anxiety and stress perception, as well as higher levels of loneliness, during the online teaching phase (lockdown), but higher grades and higher levels of motivation compared to Europeans. Indeed, Latin Americans showed greater convenience, and preference for online learning methods. However, during the face-to-face teaching phase, European students presented greater motivation and grades, showing a greater preference for this method of learning than Latin American students. Factors such as resilience, a more unfavorable and pronounced pandemic evolution, and greater social inequities, may explain the present results. Furthermore, the present study suggests that despite the effect of the pandemic on mental health, online education is postulated as an effective teaching–learning alternative. Indeed, online teaching models have come to stay, not as a substitute, but as a tool, an essential focus of attention on these models should be conducted in European countries, while the governments of Latin American countries ensure that the infrastructures and resources are equitable to be able to correctly implement this teaching model
