Resumen


El propósito de este artículo es analizar la producción e impacto de más de 3000 perfiles tomados de Google Scholar Citations con el fin de identificar qué segmentos (por género, puestos académicos y disciplinas) son más exitosos en términos de impacto científico. Este análisis se afrontó tanto desde una perspectiva estática como longitudinal. Los árboles de decisión fueron usados para detectar las variables más importantes para agrupar perfiles con un mayor número de citas por artículo e índice h. Resultados muestran que la carrera académica es el factor más importante para conseguir citas y mejorar el índice h. Los investigadores más veteranos son así los que ocupan las primeras posiciones, mientras que los jóvenes investigadores describen curriculums en ciernes. Por el contrario, estos resultados cambian cuando el crecimiento de los perfiles es observado. Así los curriculums más jóvenes son los que experimentan un crecimiento más fuerte, mientras que los más veteranos muestran signos de estabilización y estancamiento. Se concluye que los investigadores con una carrera estable pertenecientes a las ciencias de la vida tienen mejor impacto que los jóvenes investigadores de humanidades y ciencias sociales, a pesar de que estos últimos son los que más rápido crecen en número de citas por documento.
