Grupos de escrita acadêmica no Ensino Superior: Brasil e Argentina em foco

This article aims at describing the theoretical foundation, the methodological procedures and the results obtained in two pedagogical experiences of teaching academic writing in two different university contexts: the Writing Group 1st Edition, developed in Brazil with five participants, and the Club de Graduandes with nine participants, formed in Argentina, as well as analyzing the reports of its participants that show attitudes (GARRET; COOUPLAND; WILLIAMS, 2003) towards the academic writing process. The theoretical framework is based on the concept of writing as a social and political process and practice (IVANIC, 2004) capable of driving personal and professional changes and, as methodological procedures, the use of a qualitative approach (CHIZZOTTI, 1998; SUASSUNA, 2008) and content analysis (BARDIN, 2006). The results indicate that the participation in these projects provided insertion in the scientific community, as writers, reviewers and referees in the first case and entry into a professional career in the second.Este artigo busca descrever a fundamentação teórica, os procedimentos metodológicos e os resultados obtidos em duas experiências pedagógicas de ensino de escrita acadêmica em dois contextos universitários diferentes: o Grupo de Escrita 1ª edição, desenvolvido no Brasil com cinco participantes, e o Club de Graduandes com nove participantes, formado na Argentina, bem como analisar relatos de seus participantes evidenciadores de atitudes (GARRET; COOUPLAND; WILLIAMS, 2003) perante o processo de escrita acadêmica. O arcabouço teórico está pautado no conceito de escrita como processo e prática social e política (IVANIC, 2004) capaz de impulsionar mudanças pessoais e profissionais e, como procedimentos metodológicos, o uso de abordagem qualitativa (CHIZZOTTI, 1998; SUASSUNA, 2008) e análise de conteúdo (BARDIN, 2006). Os resultados indicam que as participações nesses projetos propiciaram a inserção na comunidade científica, enquanto escritores, revisores e pareceristas no primeiro caso e ingresso na carreira profissional, no segundo

Occupational sunscreen use among US Hispanic outdoor workers

Background: Occupational ultraviolet radiation (UVR) exposure is a risk factor for skin cancer, and Hispanic individuals are over-represented in a number of outdoor occupations (e.g., farming, landscaping). This study examined predictors of occupational sunscreen use in a group of US Hispanic adults who work outdoors. Results: A population-based sample of outdoor workers (n = 149, 85 % male) completed survey measures regarding their demographics, melanoma risk, perceived skin cancer risk, skin cancer knowledge, and their occupational sunscreen use. Sixty-nine percent of the sample reported never or rarely wearing sunscreen while working outdoors. Being female (p = .02), having a higher level of education (p = .03), and residing at a higher latitude (p = .04) were associated with more frequent sunscreen use. Conclusions: This study highlights the importance of interventions to promote sun protection behaviors among US Hispanic outdoor workers, and identifies potential intervention targets.Ashley K.

Understanding breast-cancer patients’ perceptions: Health information-seeking behaviour and passive information receipt

It is critical to understand patients’ information use from the patient perspective, especially when patients are from different cultures and levels of health literacy. A cross-sectional survey supplemented with interviews of breast cancer survivors including both Latina and non- Latina women was undertaken. Subjects were classified as active information seekers, passive information receivers, and/or users of information. Subjects were further classified by stage of information use, progressing from unawareness or awareness of available information to use or non-use of information to make health decisions. Information sources used and use patterns were examined. Most were active information seekers; many were also passive receivers. Healthcare providers remain the primary information source. Interpersonal communication was far more often cited than either the internet or traditional print and broadcast media. Important cross-cultural differences were found. This study provides insight into how patients use actively sought and passively received information. Despite dramatic growth of the internet and other new media, healthcare providers currently remain keys to health information. Findings may help develop more successful communication strategies when viewed in light of the National Cancer Institute’s ‘Making Health Communication Programs Work’ and the four stages it proposes. It is hoped that future work will focus on evidence-based methods to improve health communication, especially for vulnerable populations. A major lesson learned is the importance of understanding where patients decided to seek information outside the traditional provideroriented approach taken in many health education programmes

Publisher Copyright: © 2023 The Author(s)Adenosine-5-triphosphate (ATP) is the main energy vector in biological systems, thus its regeneration is an important issue for the application of many enzymes of interest in biocatalysis and synthetic biology. We have developed an electroenzymatic ATP regeneration system consisting in a gold electrode modified with a floating phospholipid bilayer that allows coupling the catalytic activity of two membrane-bound enzymes: NiFeSe hydrogenase from Desulfovibrio vulgaris and F1Fo-ATP synthase from Escherichia coli. Thus, H2 is used as a fuel for producing ATP. This electro-enzymatic assembly is studied as ATP regeneration system of phosphorylation reactions catalysed by kinases, such as hexokinase and NAD+-kinase for respectively producing glucose-6-phosphate and NADP+.publishersversionpublishe

Evaluation of molluscicidal activity of three mangrove species (Avicennia schaueriana, Laguncularia racemosa and Rhizophora mangle) and their effects on the bioactivity of Biomphalaria glabrata Say, 1818

Schistosomiasis is a disease of global extent reaching populations in social vulnerability. One of the control measures of this parasitosis is the use of molluscicidal substances that can fight snails of the genus Biomphalaria, intermediate hosts of Schistosoma mansoni. The aim of this work was to study the toxic activity of three mangrove species (Avicennia schaueriana Stapf. & Leech, ex Moldenke, 1939, Laguncularia racemosa (L.) CF Gaertn, 1807 and Rhizophora mangle L. 1753) on the biological activities of snails Biomphalaria glabrata. Hydroalcoholic extracts were prepared from the stem and leaves of each of the three plant species to which mollusks were exposed. The phytochemical analysis of plants showed the presence of important metabolites in the leaves and stems of L. racemosa and R. mangle, such as tannins and saponins, but the absence of these metabolites in A. schaueriana. Leaf and stem extracts of the three plant species showed low molluscicidal activity, not reaching the standards determined by the World Health Organization (WHO, 1983). L. racemosa and R. mangle has interfered with motility, feeding and oviposition of snails, unlike the extracts of A. schaueriana, which had no effect on these activities

ATP synthesis coupled to the electroenzymatic activity of a hydrogenase immobilized at an electrode/biomimetic membrane interface

Trabajo presentado en el XXIV International Symposium on Bioelectrochemistry and Bioenergetics (BES 2017), celebrado en Lyon del 3 al 7 de julio de 2017.Cells generate energy by coupling a proton gradient across a phospholipid bilayer membrane with the activity of a cross-membrane ATP synthase enzyme. In an effort to mimic this process in an artificial environment, we show that ATP can be efficiently produced starting from molecular hydrogen as a fuel. The proton concentration in an electrode/phospholipid bilayer interface can be controlled and monitorised electrochemically by immobilizing the membrane-bound [NiFeSe]-hydrogenase from Desulfovibrio vulgaris Hildenborough.1 The electro-enzymatic oxidation of H2 generated a proton gradient across the supported biomimetic membrane that can be coupled to the in vitro synthesis of ATP by reconstituting ATP-synthase from E. coli on the biomimetic system.2N

Isotopic Composition of Light Nuclei in Cosmic Rays: Results from AMS-01

The variety of isotopes in cosmic rays allows us to study different aspects of the processes that cosmic rays undergo between the time they are produced and the time of their arrival in the heliosphere. In this paper we present measurements of the isotopic ratios 2H/4He, 3He/4He, 6Li/7Li, 7Be/(9Be+10Be) and 10B/11B in the range 0.2-1.4 GeV of kinetic energy per nucleon. The measurements are based on the data collected by the Alpha Magnetic Spectrometer, AMS-01, during the STS-91 flight in 1998 June.Comment: To appear in ApJ. 12 pages, 11 figures, 6 table
