I paradigmi scientifici della ricerca didattica

2022

The initial positivist paradigm, derived from experimental medicine and experimental psychology, is followed by the empirical research in the didactic field, the phenomenological and the constructivist one. More recently the action research paradigm and evidence-based experimentation have been arisen. The great distinction that should be made today, as regards empirical research in the didactic field, is between the paradigms of reduction and the paradigms of complexity. The reflection on the degree of knowability of teaching practices focuses on some questions: is it pos- sible to identify similarities and coefficients between the results of research on the same theme but carried out in di…

Livelli e fattori della produttività scientifica della psicologia accademica. Una analisi bibliometrica

2015

The survey concerns the bibliometric analysis of the scientific productivity of the 8 Scientific Areas in which the Academic Italian System of Psychology is subdivided (Settori Scientifico-Disciplinari, SSD). To this end, data were retrieved from the Scopus (available at March 2012), one of the most internationally representative scientific databases. Results shows that the Scientific Areas differ from each other with respect to productivity but they tend to show similar rates of growth. Moreover, the Scientific Areas show different organizational characteristics (extension of the collaborative networks, language of publication, number of the international co-authorships); these characteris…

Impacto científico en los artículos sobre aplicaciones terapéuticas de las prácticas orientales cuerpo-mente (2006-2010)

2014

Global research on mind-body therapies is analysed, by focussing on scholarly articles on three Eastern disciplines (yoga, tai chi and qi gong) and three procedures (meditation, breathing exercises and relaxation).

We have analysed 2,363 articles published by 959 different journals. They were written by 6,583 authors from 2,162 institutions in 65 countries. Indicators of scientific productivity and impact were calculated for institutions, countries and subject areas, and the collaboration between authors and institutions was also determined. We have obser…

Scientific productivity and collaboration in viticulture and enology in Latin American countries

2013

[EN] The aim of this study was to analyze the scientific activity of Latin American researchers in viticulture and oenology through bibliometric analyses of articles included in the Science Citation Index Expanded database for the period of 2006 to 2010. A total of 917 research articles were published in 364 domestic and international journals. We highlight the important growth in the number of research papers published during the period, especially in Brazil, Argentina and Chile, as well as an increasing number of international collaborations, mainly with non-American grape- and-wine producing countries. A social network analysis of collaborations between institutions and countries was als…

SEA URCHIN RESEARCH: MILESTONES, MEMORIES, AND FUTURE CHALLENGES

2017

The sea urchin eggs and embryos have been used for nearly two centuries as experimental models for classical and modern developmental biology. In the late 1870s, the ground-breaking observations independently obtained by Hertwig and Fol highlighted for the first time that a single sperm enters the oocyte and the male and female pronuclei fuse at fertilization.1 From that point on, the seminal studies of Boveri, Driesch, and Herbst allowed conceptualization of basic biological themes, such as the chromosome theory of heredity.2 In the first half of the twentieth century, the embryo manipulation experiments performed by Hörstadius and Runnström further advanced the field, introducing the conc…

Trends analysis in the investigations realised from the data of the PISA Project

2016

Este estudio es parte de una investigación más amplia que pretende diseñar un modelo de análisis de evaluaciones de sistemas educativos que permita valorar su aportación para la cohesión social (Jornet, 2012). El punto de partida son investigaciones previas sobre el papel de las variables de contexto, de entrada y de proceso en las evaluaciones de sistemas educativos, que frecuentemente cuidan mucho más la justificación teórica y la calidad métrica de las variables de producto que estas otras, que finalmente ayudan a interpretar los resultados. En este caso realizamos revisión de los trabajos científico-académicos del corte empírico, publicados entre los años 2000 y 2012, que utilizan bases…
