Validity evidence of the Social and Emotional Nationwide Assessment (SENNA 1.0) Inventory
No full textAbstract: Given the necessity of adequate instruments to measure socio-emotional skills, this study aimed to obtain validity evidence of the Social and Emotional Nationwide Assessment inventory (SENNA 1.0). The instrument was administered to a sample of 634 students (59% females) with a mean age of 16.3 years (SD = 1.21), from eight secondary schools of the Federal District ] of Brazil. Exploratory factor analysis indicated a six factor structure that explained 42.7% of the common variance, while confirmatory factor analysis and exploratory structural equational modeling analysis showed a moderate fit to the data. Reliability coefficients of the factor scores varied between .66 and .89. The coefficients of the convergent validity with the Reduced Scale of the Big Five Personality Factors (ER5FP) had a mean value of .59. In conclusion, the results indicate satisfactory evidence for the score validity of the SENNA 1.0 inventory
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Clima organizacional: análise fatorial confirmatória de modelos de mensuração concorrentes
No full textO objetivo deste trabalho foi verificar qual modelo de mensuração para a Escala Clima Organizacional (ECO) ajusta-se melhor aos dados. Quatro modelos concorrentes foram comparados: 1) o modelo de sete fatores de Laros e Puente-Palacios; 2) um modelo de cinco fatores derivado do modelo anterior; 3) um modelo de seis fatores baseado na teoria de campo vital de Lewin; e 4) um modelo de três fatores baseado na teoria de motivação de McClelland. Foram analisados os dados de 9.901 respondentes da ECO. Os resultados de análise fatorial confirmatória indicaram o modelo de três fatores como o melhor. Todos os modelos mostram ajuste suficiente aos dados. Sugere-se que a escolha do modelo baseie-se na finalidade de uso da escala
Análise multinível: contribuições para estudos sobre efeito do contexto social no comportamento individual
No full textO reconhecimento da influência do contexto social no comportamento humano destaca a necessidade de adoção de modelos explicativos que favoreçam a identificação desse efeito. Este artigo tem o objetivo de apresentar as características teóricas e técnicas dos modelos multinível, pois eles cumprem com essa exigência. Em uma perspectiva teórica, a escolha dos modelos em discussão deveria ser baseada, tanto quanto possível, em uma teoria multinível que evidenciasse o papel preditivo de variáveis oriundas de diferentes níveis. A construção de modelos guiada por uma teoria levará a modelos mais frutíferos e com maior validade externa, em comparação com modelos construídos com pouco ou nenhum sustento teórico. Do ponto de vista técnico, a análise multinível é similar à análise de regressão; assim, obedece a muitas das suas exigências. Este trabalho permite concluir sobre as vantagens dos modelos multinível para pesquisadores interessados na identificação do efeito do contexto no comportamento humano
