Authorship analysis of specialized vs diversified research output     

Giovanni Abramo  Ciriaco Andrea D’Angelo  Flavia Di Costa 《Journal of Informetrics》2019,13(2):564-573

The present work investigates the relations between amplitude and type of collaboration (intramural, extramural domestic or international) and output of specialized versus diversified research. By specialized or diversified research, we mean within or beyond the author’s dominant research topic. The field of observation is the scientific production over five years from about 23,500 academics. The analyses are conducted at the aggregate and disciplinary level. The results lead to the conclusion that in general, the output of diversified research is no more frequently the fruit of collaboration than is specialized research. At the level of the particular collaboration types, international collaborations weakly underlie the specialized kind of research output; on the contrary, extramural domestic and intramural collaborations are weakly associated with diversified research. While the weakness of association remains, exceptions are observed at the level of the individual disciplines.  相似文献   

On the relation between the degree of internationalization of cited and citing publications: A field level analysis,including and excluding self-citations     

Giovanni Abramo  Ciriaco Andrea D’Angelo  Flavia Di Costa 《Journal of Informetrics》2021,15(1):101101

The growing complexity of scientific challenges demands increasingly intense research collaboration, both domestic and international. The resulting trend affects not only the modes of producing new knowledge, but also the way it is disseminated within scientific communities. This paper analyses the relationship between the “degree of internationalization” of a country’s scientific production and that of the relevant citing publications. The empirical analysis is based on 2010-2012 Italian publications. Findings show: i) the probability of being cited increases with the degree of internationalization of the research team; ii) totally domestic research teams tend to cite to a greater extent totally domestic publications; iii) vice versa, publications resulting from international collaborations tend to be more cited by totally foreign publications rather than by publications including domestic authors. These results emerge both at overall and at discipline level. Findings might inform research policies geared towards internationalization.  相似文献   

Home book reading and reading achievement in EU countries: the Progress in International Reading Literacy Study 2011 (PIRLS)     

Luisa Araújo  Patricia Costa 《Educational Research and Evaluation》2013,19(5-6):422-438

Home shared book reading during the preschool years is a strong predictor of students’ reading achievement in primary school, and, according to Sénéchal (2012), it can benefit more children from low socioeconomic status (SES) backgrounds. This study examines the association between frequency of book reading before the start of compulsory education and the reading achievement of 4th-grade students whose parents have high and low education levels in 22 European countries. Using data from the Progress in International Reading Literacy Study (PIRLS 2011), we show that the contribution of shared reading for the achievement of students from distinct SES backgrounds is different in different countries and that shared reading does not always benefit more children from low-SES backgrounds. Results are discussed in light of Sénéchal's home literacy model, the dynamics of cultural capital, and current policy efforts to support children's literacy development in European countries.  相似文献   

Orthography and the development of metalinguistic reflection in Portuguese primary school pupils / Ortografía y desarrollo de la reflexión metalingüística en alumnos portugueses en primaria

Abstract

Linguistic awareness is crucial in learning literacy. This project has a two-fold aim: to develop the students’ ability to think about language in order to write with accuracy and to lead teachers to promote students’ discussions about their writing difficulties. The study is part of a two-year action-research project developed in primary schools from the Lisbon area, with experimental and control groups. The starting point of the project was the analysis of the problems students of third and fourth grades showed in their writing. The scope of the project includes dictation tasks within an interactionist approach, favouring grammatical discussions leading to the observation and manipulation of linguistic data.  相似文献

Evaluating the perception of disability and the inclusive education of teachers: the Italian validation of the Sacie-R (Sentiments,Attitudes, and Concerns about Inclusive Education – Revised Scale)     

Anna Maria Murdaca  Sebastiano Costa 《欧洲特需教育杂志》2018,33(1):148-156

This study aimed to verify the factorial structure, internal validity, reliability, and criterion validity of The Sentiments, Attitudes and Concerns about Inclusive Education Revised Scale (SACIE-R) in an Italian sample. The SACIE-R is a useful tool to measure three aspects of teachers’ perceptions about inclusion, which are Sentiments, Attitudes and Concerns, providing valuable information to address the needs of teachers working with special students. A measure of this construct is currently not available in Italian, and a validation process is required. In order to provide an initial psychometric evaluation of the Italian adaptation, the SACIE-R was translated for use in Italian-speaking populations. Four hundred Italian teachers enrolled in educational teaching courses completed the SACIE-R. Confirmatory factor analyses demonstrated a good fit to the hypothesised 3-factor model, and adequate internal consistency for the scale was evidenced. A confirmatory factor analysis showed the same factor structural validity as the original instrument (although some items in the original version were deleted). Furthermore, taken together, the results showed a good level of reliability, and convergent and discriminant validity. Finally, the Italian version of the SACIE-R has good psychometric characteristics that can make it a useful measure of teacher attitude toward inclusion in the Italian educational context.  相似文献   

Contribution of limbs’ actions to the four competitive swimming strokes: a nonlinear approach     

Raul F. Bartolomeu  Mário J. Costa  Tiago M. Barbosa 《Journal of sports sciences》2018,36(16):1836-1845

The aim of our study was to assess the effect of the limbs’ actions on the nonlinear properties of the four competitive swimming strokes. Forty-nine swimmers performed all-out sprints at front-crawl, backstroke, breaststroke and butterfly, each one at full stroke (FS), only the arms’ stroke (AS), and only leg kicking (LK), in a total of 12 bouts, 6 per day. A speedo-meter cable was attached to the swimmer’s hip, to collect the speed-time raw data (f = 50Hz). Velocity, speed fluctuation, sample entropy and fractal dimension were derived from the speed-time series. Significant and moderate-strong effects were noted for both stroke and condition in all variables in the study (p ≤ 0.001; 0,560<η² < 0,952). The four competitive strokes and their three conditions exhibited nonlinear properties. The swimming pattern was less complex and more predictable for LK in comparison to AS and FS. Breaststroke and butterfly have more complex but more predictable patterns than backstroke and front-crawl.  相似文献
