Variáveis de controle sobre responder ordinal: revisitando estudos empíricos

Questões conceituais dentro dos sistemas explicativos em Psicologia podem ser trabalhadas através da busca dos termos e das condições definidoras de um determinado conceito ou fenômeno. Estudos de análise conceitual visam verificar quais os termos que não fazem parte de um conceito, a aplicação correta de um conceito já existente e em quais casos esse conceito pode ser aplicado. Visam a discriminação entre classes de eventos e a generalização intra classe. A aquisição e manutenção de cadeias comportamentais tem recebido o nome de encadeamento, referindo-se a sucessões de respostas, nas quais uma resposta produz as condições de estímulo para a resposta seguinte. Pode-se avaliar que grande parte do repertório dos organismos parece ocorrer de maneira organizada seqüencialmente em uma sucessão contínua. O comportamento ordinal vem sendo estudado através do exame do efeito de diferentes variáveis. Entretanto, a literatura operante tem mostrado diferentes termos para se referir ao fluxo contínuo e à sucessão de respostas. Esta pesquisa propôs verificando o comportamento lógico de alguns conceitos relacionados ao responder ordinal, investigando o nível de instrumentalidade através da especificação das variáveis controladoras nos procedimentos aplicados no âmbito da Análise Experimental do Comportamento. Por meio de algumas palavras-chave o material bibliográfico foi buscado em bancos de dados de periódicos científicos e livros da área. Em seguida, os trabalhos foram organizados em seis grupos diferentes de acordo com a semelhança em seus títulos e resumos. Por último, foram analisados destacando-se as principais variáveis envolvidas em cada tipo de procedimento. Foram selecionados 82 trabalhos, 14 artigos nacionais, 65 estrangeiros e 3 capítulos de livro, um nacional e dois estrangeiros. A análise descritiva das pesquisas demonstrou que nos grupos 2, 5 e 6 foi possível acessar informações comuns a todos os estudos. Além disso, verificou-se que o modelo analítico-comportamental de cadeia de respostas pareceu ser evidente nos estudos dos quatro primeiros grupos. Portanto, a verificação das variações de procedimento presentes nos experimentos possibilitou a organização e delimitação das variáveis envolvidas nos estudos sobre o responder ordinal. Tais informações poderão funcionar como um parâmetro de controle experimental no desenvolvimento de estudos futuros, bem como subsidiar investigações que visem verificar o efeito de variações de procedimento dentro de um mesmo grupo sobre o desempenho encontrado nos resultados dos estudos. Além disso, constatou-se que o emprego de um termo pode ser definido pelo contexto no qual o conhecimento é produzido, pois, os determinantes de um termo científico são produtos da complexidade de um contexto social que engendra mudanças no modo de tratar um determinado objeto de estudo.

Padrões de busca e uso de artigos científicos: um estudo com pós-graduandos em educação brasileiros

This article presents part of a larger study on the use of reference sources to perform bibliographical search by graduate students in Education. Data relating to the use of the scientific journals by these students are presented and discussed. Sixty Education graduate students, 28 Master degree and 32 Doctoral, answered an electronic questionnaire. The students indicated the types of articles usually read and the importance attributed to each one. For each of treated themes in the electronic questionnaire, data are initially presented and analyzed in the set of the 60 participants of the study and then compared between master and doctoral students. Were used the Chi-squared (?2) test, the Fisher exact test and the Spearman’s correlation coefficient. Research reports were more frequently pointed out but less valued in comparison to articles referring to critical review and theoretical essay. Methodological articles, appearing in fourth position according to reading frequency and importance attributed, are more valued by doctoral than master students. The students read these articles using different procedures. The possible reasons for the students valorizing the articles of critical review and theoretical essays are discussed. The present study intends to offer a contribution to understand the use of scientific information by students, describing some graduate students’ habits related to information seeking in scientific journals, and reading of the articles published.

A indução da potencialização pós-ativação através dos saltos: pliométrico e vertical

The Post-Activation Potentiation (PAP) offers a proposal to optimize the production of strength and muscular power when performing exercises near maximum to actions previously assessed . The present study aims to show the activation process of postactivation potentiation (PAP) through vertical and plyometric jumps, and explain the user function of these movements. The ratio of post-activation potentiation resulting from plyometric and vertical jumps and explosive strength in the lower limbs aims to improve the potency and maximal strength, proven through studies and protocols detailed here. The results of this research come can be applied both for athletes and for individuals with experience in strength training and jumps (sports like volleyball, basketball and handball). The study was conducted through a literature review, conducted in scientific journals indexed in major databases (PubMed, ISI-Web of Science, SCIELO), books and academic papers (theses and dissertations)

Proposta de elaboração de um glossário bilíngue de termos simples, expressões fixas e semifixas da área de sensoriamento remoto

Brazil was one of the countries that stood out in the list of nations that publishes more articles in scientific journals. From 2007 to 2008, the Brazilian scientific production has moved from 15th to 13rd place in the world ranking published articles in professional journals. However, 60% of articles published by the Brazilians are in Portuguese, which makes the Brazilian work have little international attention. The purpose of this research is to build and analyze a parallel corpus composed of a book of Remote Sensing and its translation in the direction English into Portuguese in order to create a glossary of most recurrent terms in the literature of Remote Sensing. The achievement of these goals will take for theoretical and methodological foundation the Corpus-Based Translation Studies (BAKER, 1993, 1995, 1996; CAMARGO, 2005), Corpus Linguistics (BERBER SARDINHA, 2004) and principles of Terminology (BARROS, 2004; KRIEGER & FINATTO, 2004). It will also use Wordsmith Tools program and its tools. Besides the parallel corpus, we will also build two comparable corpora respectively from articles published in Brazilian and international journals in the area. The first results show that the translators made use of greater variation of vocabulary in their translations, which can be a way to make the text more clear to the reader. For the analysis of glossary entries, professionals from the National Institute for Space Research - INPE, will be consulted and their views aggregated to this research to give consistency to the production of the proposed bilingual glossary.

Nutrição mineral e qualidade do fruto do abacaxizeiro e do maracujazeiro

Several factors influence the productivity and fruit quality of pineapple and passion fruit, among which are: climate, soil fertilization and irrigation practices. Mineral nutrition is essential to increase productivity and improve fruit quality; however, there is a few information about the effect of fertilization in these two fruit crops, especially under tropical conditions. The objective of this review was to compile the main research results, in which the influence of mineral nutrition on the fruit quality was evaluated. We considered the information recently published in scientific journals, and presented it for the macronutrients individually, then to NPK and, finally, the micronutrients. The review showed that it is difficult to say that some element favors or not certain characteristics of pineapple and passion fruit fruits, since the results are inconsistent and there is not many information. More than established the effects of mineral nutrients on the fruit quality of these two fruit crops, we stand out that research in this topic is very necessary.

Privatização da educação no Brasil: como o tema vem sendo tratado em publicações de periódicos que estão no Scielo

Education is a basic right of every citizen guaranteed by the Federal Constitution of 1988, so that everyone is able to exercise their civil, political, economic and social. But in Brazil, this right has not yet been effected in all its concreteness and current privatization strategy have brought change to the right to education. Recent research from GREPPE (Group of Studies and Research in Educational Policy) identify different modalities of privatization of basic education, with emphasis on the privatization of supply, management and organization of the pedagogical work through the adoption of private educational systems. This study aimed to identify and discuss how the issue of privatization of education in Brazil is currently being treated in journal articles contained in the database SciELO - Scientific Electronic Library Online. SciELO is an electronic library covering a selected collection of Brazilian scientific journals. The research is qualitative and the same descriptors privatization were used + education

Aposentadoria e exergames: uma revisão integrativa da literatura sobre a possibilidade da prática de atividades físicas por idosos por meio de exergame

The practice of physical exercise and the adopting of a healthy lifestyle are some of the ways to minimize the physiological and pathological changes associated with aging. Therefore, it is interesting to search for new technologies that encourage the elderly to practice physical activities, such as Exergames. In this study, an integrative review was carried out through electronic databases, journals and scientific journals searching for articles and publications that relate the use of exergames by retirees and testing the viability of these technologies towards this target public. A total of twenty-seven articles made part of the review. After analyzing the results, it's clear that exergames are one of the pertinent options to motivate this public to adhere in a healthier lifestyle, being able to improve the physical, cognitive abilities and improve emotional states of its practitioners, can vary the intensity of exercise in accordance with the personal limitations of each one. But certain care and adjustments need to be made before starting to practice them
