Student performance and its evaluation remain a serious challenge for education systems. Frequently, the recording and processing of students’ scores in a specific curriculum have several flaws for various reasons. In this context, the absence of data from some of the student scores undermines the efficiency of any future analysis carried out in order to reach conclusions. When this is the case, missing data imputation algorithms are needed. These algorithms are capable of substituting, with a high level of accuracy, the missing data for predicted values. This research presents the hybridization of an algorithm previously proposed by the authors called adaptive assignation algorithm (AAA), with a well-known technique called multivariate imputation by chained equations (MICE). The results show how the suggested methodology outperforms both algorithms.

Nowadays, the quality standards of higher education institutions pay special attention to the performance and evaluation of the students. Then, having a complete academic record of each student, such as number of attempts, average grade and so on, plays a key role. In this context, the existence of missing data, which can happen for different reasons, leads to affect adversely interesting future analysis. Therefore, the use of imputation techniques is presented as a helpful tool to estimate the value of missing data. This work deals with the academic records of engineering students, in which imputation techniques are applied. More specifically, it is assessed and compared to the performance of the multivariate imputation by chained equations methodology, the adaptive assignation algorithm based on multivariate adaptive regression splines and a hybridization based on self-organisation maps with Mahalanobis distances and AAA algorithm. The results show that proposed methods obtain successfully results regardless the number of missing values, in general terms.

Reflection on the development of bioethics in pharmaceutical professional organizations. Professional excellence Reflexão sobre o desenvolvimento da Bioética nas organizações profissionais farmacêuticas. A excelência profissional For some years, the collegiate organizations of the pharmaceutical profession are being challenged, not only by external agents, but also by the professionals themselves. There is a certain criticism in the response, especially in aspects that have to do with the role they must play in the development and activity of professional practice, in their domestic, external and internal purposes and in the characteristics they must possess as organizations in service of these professionals and society. We understand that the development, revision and updating of Bioethics, as well as training in this field in professional organizations, contributes to that transcendent excellence in the profession, provokes a real knowledge of it in all its dimensions and with the power to act in total freedom from threats or internal or external restrictions.

Este trabajo pretende colaborar a facilitar la tarea docente del profesorado, que debe desarrollar a través de sus decisiones de departamento, la enseñanza del hecho religioso como alternativa a unas enseñanzas de las religiones confesionales, en los dos últimos cursos de la ESO y en el primer curso del Bachillerato. Este aspecto nos orienta a desarrollar el currículo de esta nueva materia, preferentemente, hacia el vector cultural y social del hecho religioso, reservado a las enseñanzas comprometidas con una determinada crrencia religiosa -voluntariamente elegida por el alumnado- la preferencia en el desarrollo de los contenidos confesionales de la religión

This paper argues that narrative elements from the science fiction (SF) literary genre are used in the discourse of Nanoscience and Technology (NST) to bridge the gap between what is technically possible today and its inflated promises for the future. The argument is illustrated through a detailed discussion of two NST texts. The paper concludes by arguing that the use of SF narrative techniques poses serious problems to the development of a critical analysis of the ethical and social implications of NST
