In the fast developing world of scholarly communication it is good to take a step back and look at the patterns and processes of innovation in this field. To this end, we have selected 101 innovations (in the form of tools & sites) and graphically displayed them by year and also according to 6 phases of the research workflow: collection of data & literature, analysis, writing, publishing & archiving, outreach and assessment. This overview facilitates discussion on processes of innovation, disruption, diffusion, consolidation, competition and success, but also of failure and stagnation, over the last 3 decades. We describe some of the trends, expectations, uncertainties, opportunities and challenges within each of the workflow phases. Also, based on the graphical overview we present a juxtaposition of typical traditional, innovative and experimental workflows.

The UK’s most recent Research Excellence Framework (REF2014), for the first time evidenced the economic and societal impact of university research through a total of 6,975 case studies. This Digital Research Report on ‘The Diversity of UK Research and Knowledge’ introduces this dataset and contains visualisations of the knowledge networks underpinning the impact of UK university research. Alongside it lies an interactive visualisation, see www.digital-science.com/visualizations/ref-case-study-similarity-network.

Alternative metrics (altmetrics) as a possible substitute for or addition to the traditional methods of assessing scientific results based on opinions and bibliometric indicators were first proposed in 2010. Since then, metric indicators, primarily those based on accounting for the use and discussion of scientific publications on the Internet, have, on the one hand, found influential advocates among scientists and publishers and, on the other, been met with resistance on the part of equally authoritative participants in the market of scientific publications. Altmetrics are already used actively by the largest publishers; in June 2014, the American National Information Standards Organization developed a draft altmetrics standard. This article presents a review of the existing indicators, describes their target audience, and considers leading companies that develop software products on altmetrics calculation for users of different categories. Altmetrics and citation-based indicators are ...

Scientometrics is the study of the quantitative aspects of the process of science as a communication system. It is centrally, but not only, concerned with the analysis of citations in the academic literature. In recent years it has come to play a major role in the measurement and evaluation of research performance. In this review we consider: the historical development of scientometrics, sources of citation data, citation metrics and the “laws" of scientometrics, normalisation, journal impact factors and other journal metrics, visualising and mapping science, evaluation and policy, and future developments Authors: John Mingers; Loet Leydesdorff Source: European Journal of Operational Research (in press) URL:   Full text

Por medio de la presente nos dirigimos a usted, pues hemos leído con interés la publicación “Estado nutricional en estudiantes universitarios: su relación con el número de ingestas alimentarias diarias y el consumo de macronutrientes” de Pi et al1 . En este estudio, los autores utilizaron como métodos antropométricos el Índice de Masa Corporal (IMC), la Circunferencia Abdominal (CA) y la Bioimpedancia Eléctrica (BIA) para estimar el estado nutricional y la composición corporal (CC). Se sabe que la BIA es usada para la estimación de la grasa corporal, sin embargo es específica para cada población, por lo que es necesario validar en cada población de estudio para disminuir un potencial sesgo de medición .

Introducción: El personal de emergencia convive habitualmente con riesgos inherentes a su profesión. Objetivos: Profundizar acerca del concepto del riesgo percibido como herramienta para gestionar el riesgo ocupacional. Materiales y métodos: El modelo utilizado para la cuantificación del riesgo ha sido el paradigma psicométrico. De esta forma, se realizaron encuestas anónimas en las diferentes estaciones de bomberos. El cuestionario contenía preguntas sociodemográficas, nueve preguntas acerca de distintos atributos del riesgo y una pregunta acerca de la percepción del riesgo en general del sujeto. Resultados: El análisis estadístico muestra dos grupos claramente diferenciados en cuanto a su percepción del riesgo, siendo uno de ellos caracterizado por tener sus integrantes una alta percepción del riesgo y el otro por tener una baja percepción del riesgo. Por último, se muestra que solamente el nivel educacional era una variable significativa en la explicación del riesgo percibi...
