Cluster randomized controlled trials (cluster RCTs) randomize whole clusters of individuals in testing two or more competing interventions. Here we will present the ethical problems raised by cluster RCTs concerning their effect on inequality. We argue that some inequalities generated by cluster RCTs are larger in scope than those generated from individual RCTs. We also argue that any cluster RCT-generated inequalities, which divide groups rather than individuals, are more problematic in type than the inequalities created in individual RCTs. These concerns (...) should be taken into consideration when designing research at the cluster level, and those conducting the research should consider modified research design strategies in cases where they believe the risk of generating inequalities is large.

La profusa utilización del concepto de buen gobierno en los discursos políticos y mediáticos puede conducirnos a pensar que estamos ante una innovación conceptual del presente. Pero lo cierto es que se trata de un viejo concepto que hunde sus raíces en la teoría política clásica y se resiste a una definición clara y precisa. El artículo pretende reflexionar sobre los principales cambios experimentados por el buen gobierno y su metamorfosis en gobernanza, analizándolo como una narrativa de transformación conceptual, en (...) la que se ha pasado de una lógica normativa a una lógica tecnocrática.

The aim of this article is to examine whether informational manipulation, used intentionally by the researcher to increase recruitment in the research study, can be morally acceptable. We argue that this question is better answered by following a non-normative account, according to which the ethical justifiability of informational manipulation should not be relevant to its definition. The most appropriate criterion by which informational manipulation should be considered as morally acceptable or not is the researcher’s special moral duties towards their subjects. (...) We also propose that a broader definition of manipulation of information should be adopted (than that already existing in the literature) since informational manipulation can affect not only a person’s beliefs but also their desires in decision-making. We conclude that manipulation of information can either be used to protect the potential subject and facilitate the informed consent process or be used to exploit and merely use a person for scientific goals.

The knowledge extraction from data with noise or outliers is a complex problem in the data mining area. Normally, it is not easy to eliminate those problematic instances. To obtain information from this type of data, robust classifiers are the best option to use. One of them is the application of bagging scheme on weak single classifiers. The Credal C4.5 model is a new classification tree procedure based on the classical C4.5 algorithm and imprecise probabilities. It represents a type of (...) the so-calledcredal trees. It has been proven that CC4.5 is more robust to noise than C4.5 method and even than other previous credal tree models. In this paper, the performance of the CC4.5 model in bagging schemes on noisy domains is shown. An experimental study on data sets with added noise is carried out in order to compare results where bagging schemes are applied on credal trees and C4.5 procedure. As a benchmark point, the known Random Forest classification method is also used. It will be shown that the bagging ensemble using pruned credal trees outperforms the successful bagging C4.5 and RF when data sets with medium-to-high noise level are classified. (shrink)

El anuario del Instituto Cervantes del 2018 lo constató primero: El español está en auge. Prospectivamente, no obstante, el porvenir del español dependerá forzosamente de factores más allá de lo casuístico: profesores innovadores, mejores recursos y metodologías originales. La influencia de que editoriales como Cambridge han tenido en España ha hecho que, durante años, los estudiantes de español como lengua extranjera hayan aprendido español de la mano de “las cuatro destrezas”. Bajo las mismas, los libros proponen unidades entorno a temas (...) arbitrarios. Las páginas siguientes, por el contrario, proponen un modelo alternativo y rejuvenecedor: un nuevo programa de enseñanza basado en la ley educativa francesa conocida como ‘Las Nociones Culturales’.
