The political dimension of environmental education into research of Brazilian journals of science education

O presente texto tem como objetivo sistematizar resultados relacionados com a dimensão política da educação ambiental apresentada em artigos que estabelecem relações entre educação ambiental e o ensino das Ciências da Natureza, destacando aspectos em termos de democracia, cidadania e justiça social. Busca-se evidenciar o contexto da educação básica que tem sido privilegiado nessas pesquisas, tais como, áreas curriculares, temas ambientais, temas de estudo que têm sido selecionados pelos investigadores que se voltam para essa temática. As análises apontam certa predominância das perspectivas críticas em educação ambiental como referencial teórico. Por outro lado, constata-se que a dimensão política tem sido pouco considerada como foco de investigação e nas conclusões dos artigos analisados. Conclui-se, pela necessidade de maior explicitação sobre sentidos do que vem a ser a dimensão política da educação ambiental, pois por de trás dos consensos em torno dessa dimensão se escondem modelos de sociedade e de democracia que precisam ser discutidos. ABSTRACT: Through an analysis of texts linking environmental education to science education, this article aims to highlight the political dimensions of democracy, citizenship and social justice. It seeks to emphasize the context of compulsory education that has privileged research on certain curriculum areas, environmental issues and topics that have been selected by the researchers. The analyses indicated a slight predominance of critical perspectives on environmental education as a preferred theoretical framework. Taking into consideration that there are societal models underlying the consensus on this dimension that remain hidden and need to be brought out into the open to be critically discussed, we propose more clarification in this point. Likewise, we conclude that there is a need for greater clarification of the meaning of the political dimension of environmental education

Epidemiologic aspects of the malaria transmission cycle in an area of very low incidence in Brazil

BACKGROUND: Extra-Amazonian autochthonous Plasmodium vivax infections have been reported in mountainous regions surrounded by the Atlantic Forest in Espírito Santo state, Brazil. METHODS: Sixty-five patients and 1,777 residents were surveyed between April 2001 and March 2004. Laboratory methods included thin and thick smears, multiplex-PCR, immunofluorescent assay (IFA) against P. vivax and Plasmodium malariae crude blood-stage antigens and enzyme-linked immunosorbent assay (ELISA) for antibodies against the P. vivax-complex (P. vivax and variants) and P. malariae/Plasmodium brasilianum circumsporozoite-protein (CSP) antigens. RESULTS: Average patient age was 35.1 years. Most (78.5%) were males; 64.6% lived in rural areas; 35.4% were farmers; and 12.3% students. There was no relevant history of travel. Ninety-five per cent of the patients were experiencing their first episode of malaria. Laboratory data from 51 patients were consistent with P. vivax infection, which was determined by thin smear. Of these samples, 48 were assayed by multiplex-PCR. Forty-five were positive for P. vivax, confirming the parasitological results, while P. malariae was detected in one sample and two gave negative results. Fifty percent of the 50 patients tested had IgG antibodies against the P. vivax-complex or P. malariae CSP as determined by ELISA. The percentages of residents with IgM and IgG antibodies detected by IFA for P. malariae, P. vivax and Plasmodium falciparum who did not complain of malaria symptoms at the time blood was collected were 30.1% and 56.5%, 6.2% and 37.7%, and 13.5% and 13%, respectively. The same sera that reacted to P. vivax also reacted to P. malariae. The following numbers of samples were positive in multiplex-PCR: 23 for P. vivax; 15 for P. malariae; 9 for P. falciparum and only one for P. falciparum and P. malariae. All thin and thick smears were negative. ELISA against CSP antigens was positive in 25.4%, 6.3%, 10.7% and 15.1% of the samples tested for "classical" P. vivax (VK210), VK247, P. vivax-like and P. malariae, respectively. Anopheline captures in the transmission area revealed only zoophilic and exophilic species. CONCLUSION: The low incidence of malaria cases, the finding of asymptomatic inhabitants and the geographic separation of patients allied to serological and molecular results raise the possibility of the existence of a simian reservoir in these areas

Quantifying the third sector in Portugal : an overview and evolution from 1997 to 2007

I am grateful to the Portuguese Ministry of Labor and Social Solidarity, Statistics Department, for access to the data used in this study (Quadros de Pessoal). I would also like to express my gratitude to Miguel Reis Portela and Nelson Areal for their assistance in dealing with the database and STATA. I am also indebted to two anonymous reviewers for their useful comments on an earlier version of this paper.This paper presents a global overview of the third sector in Portugal drawing on data from a linked employer-employee database – “Quadros de Pessoal”, which is based on a compulsory annual inquiry to organizations, making it a better source of information than those based on sample surveys and estimates. This study advances on previous overviews by providing more updated numbers for organization size, age, gross revenue and employment levels, as well as their distribution across the ICNPO third sector activity classification. The evolution of these variables from the period 1997-2007 is also analyzed. The Portuguese third sector has been fast growing, with revenues amounting to 5.64% of Portugal’s GDP and employment representing 4% of the country’s employment in 2007. It is mainly composed of very small organizations, with diminutive revenues. Perhaps its most striking features are the uneven distribution of employment and revenue and the strong concentration on Social services

Helminth infections and gut microbiota - a feline perspective

$\textbf{BACKGROUND}$: Investigations of the relationships between the gut microbiota and gastrointestinal parasitic nematodes are attracting growing interest by the scientific community, driven by the need to better understand the contribution of parasite-associated changes in the composition of the gut flora to both host malnutrition and immune modulation. These studies have however been carried out mainly in humans and experimental animals, while knowledge of the make-up of the gut commensal flora in presence or absence of infection by parasitic nematodes in domestic animals is limited. In this study, we investigate the qualitative and quantitative impact that infections by a widespread parasite of cats (i.e. $\textit{Toxocara cati}$) exert on the gut microbiota of feline hosts. $\textbf{METHODS}$: The faecal microbiota of cats with patent infection by $\textit{T. cati}$ (= $\textit{Tc+}$), as well as that of negative controls (= $\textit{Tc-}$) was examined via high-throughput sequencing of the V3-V4 hypervariable region of the bacterial 16S rRNA gene, followed by bioinformatics and biostatistical analyses of sequence data. $\textbf{RESULTS}$: A total of 2,325,366 useable high-quality sequences were generated from the faecal samples analysed in this study and subjected to further bioinformatics analyses, which led to the identification of 128 OTUs and nine bacterial phyla, respectively. The phylum Firmicutes was predominant in all samples analysed (mean of 53.0%), followed by the phyla Proteobacteria (13.8%), Actinobacteria (13.7%) and Bacteroidetes (10.1%). Among others, bacteria of the order Lactobacillales, the family $\textit{Enterococcaceae}$ and genera $\textit{Enterococcus}$ and $\textit{Dorea}$ showed a trend towards increased abundance in $\textit{Tc+}$ compared with $\textit{Tc-}$ samples, while no significant differences in OTU richness and diversity were recorded between $\textit{Tc+}$ and $\textit{Tc-}$ samples ($\textit{P}$=0.485 and $\textit{P}$=0.581, respectively). However, Canonical Correlation and Redundancy Analyses were able to separate samples by infection status ($\textit{P}$=0.030 and $\textit{P}$=0.015, respectively), which suggests a correlation between the latter and the composition of the feline faecal microbiota. $\textbf{CONCLUSIONS}$: In spite of the relatively small number of samples analysed, subtle differences in the composition of the gut microbiota of $\textit{Tc+}$ vs $\textit{Tc-}$ cats could be identified, some of which in accordance with current data from humans and laboratory animal hosts. Nevertheless, the findings from this study contribute valuable knowledge to the yet little explored area of parasite-microbiota interactions in domestic animals.This work was supported by Merial Pty Ltd (CC, AG, DO) and ESCCAP UK & Ireland (CC).

Satisfação no trabalho da equipe de enfermagem: revisão integrativa

Job satisfaction consists of a feeling of wellbeing, resulting from the interaction of several occupational aspects, and may influence the worker's relationship with the organization, clients and family. Hence, it becomes important for the quality of nursing care to reflect on this topic in depth. Therefore, this study aimed to examine the scientific evidence related to job satisfaction in Brazilian nursing. An integrative literature review was carried out in the databases LILACS, MEDLINE, BDENF and Cochrane Library, totaling 17 publications, categorized in: Job Satisfaction, Job Dissatisfaction and Associated Factors. It was concluded that job satisfaction is determined by a complex network of factors and may vary depending on the group studied. Additional research, particularly of evidence level III in different nursing fields, covering all of Brazil, is necessary to support the implementation of occupational improvements.La satisfacción en el trabajo consiste en un sentimiento de bienestar resultante de la interacción de varios aspectos ocupacionales, pudiendo influenciar la relación del trabajador con la organización, clientes y familia.

First report of the blaOXA-58 gene in a clinical isolate of Acinetobacter baumannii in Rio de Janeiro, Brazil

Carbapenemase production is an important mechanism of carbapenem resistance among nonfermentative Gram-negative isolates. This study aimed to report the detection of blaOXA-58 gene in multiresistant clinical isolates of Acinetobacter baumannii recovered from inpatients in a public hospital. Polymerase chain reaction tests were performed to detect the blaOXA-23-like, blaOXA-24-like, blaOXA-58-like and blaOXA-51-like genes. The blaOXA-58 and blaOXA-23 genes were detected in one and three isolates, respectively. Sequencing of the blaOXA-58-like amplicon revealed 100% identity with the A. baumannii blaOXA-58 gene listed in the GenBank database. This is the first report of an OXA-58-producing A. baumannii isolate in Rio de Janeiro, Brazil
