El proceso general de aceleración social que caracteriza estructuralmente a las sociedades tardomodernas tiene un impacto considerable en la mayoría de las prácticas sociales cotidianas. Este número especial se propone examinar los efectos de la aceleración social sobre las prácticas sociales desde una doble perspectiva: descriptivo-explicativa y normativo-ética. En este artículo introductorio, los editores sientan las bases teóricas del número. Antes de presentar brevemente las contribuciones del volumen, se exponen los conceptos clave que lo estructuran —a saber, «aceleración social», «prácticas sociales», «crítica normativa» y «orientaciones éticas»— y se analizan sus interrelaciones.

El elemento dominante de las tradiciones religiosas proféticas de Occidente es de naturaleza histórico-institucional y dogmática. En estas tradiciones, para Harold Bloom, Dios encarna la absoluta transcendencia y algo radicalmente externo al yo. Una vía alternativa, ha existido y pervive de forma pluriforme en esas mismas tradiciones, solapada bajo sus manifestaciones místicas, “el camino de la gnosis”. Esta gnosis, que ha pervivido durante dos mil años, puede definirse como la aceptación y el conocimiento del Dios que hay en el interior del ser humano. Nuestro objetivo en este artículo es abordar críticamente esta concepción bloomiana de la gnosis y su aplicación, como modelo hermenéutico, a su interpretación de la “religión americana”, la “fe religiosa estadounidense”, una ‒supuesta‒ fe sincrética, milenarista y del retardo, donde el medio divino se funde en la cotidianeidad del individuo, en la libérrima interioridad del yo.

In this paper we criticize the existing contradictions in the context of bone marrow donor records in Spain. On the one hand there is the necessity to register as many patients as possible to maximize the opportunities to access a bone marrow transplant and on the other the always important economic issue of having to perform the relevant histocompatibility tests. In fact, these records are globally coordinated with each other to provide a wide range of potential donors and make better use of existing resources. It should be noted that many patients who should have a transplant but who do not achieve a sufficient donor support must follow a medical treatment with high economic costs with tragic results for many of them. For example, those suffering from certain types of leukemia, when not finding that compatible donor, must follow chemotherapy-based treatments. There are also cord blood units banks which allow performing these transplants, also coordinated at the international level. Therefore, according to the principle of reciprocity, it is not justifiable that some countries are doing an important economic effort to have a large registration while others take advantage without making an equivalent effort according to their economic and population size

En la actividad científica se pueden distinguir tres tipos principales de representación científica: proyectiva, subsuntiva y reductiva. Tras unas breves considcraciones introductorias, se presentan las características más destacadas de cada uno de estos tres tipos principales de representación científica y se abstrae a partir de ellas el esquema al que toda Teoría General de la Representación Científica se debe adecuar. A continuación se exponen las lineas generales de la principal propuesta presente en la literatura para desarrollar TGRC y se hacen algunas consideraciones criticas. La conclusión provisional es que esta propuesta tiene, al menos por el momento, el problema de ser, o bien demasiado liberal, o bien demasiado conservadora. Por último, se propone un enfoque alternativo a explorar que pretende estar libre de los problemas deI anterior.We can distinguish three main types of representation in scientific practice: projective, subsuntive and reductive. After some brief introductory remarks, we present the more salient characteristics of these three main types of scientific representation and we abstract from them a scheme that any General Theory for Scientific Representation must fit. Then we offer the general traits of the main existing proposal for a GTSR and we make some criticisms. The provisional conclusion is that this proposal is, as it stands, either too liberal or too conservative. Finally, we propose to explore an alternative approach which intends to solve these difficulties.

In the present work, an artificial neural network (ANN) will be developed to estimate the relative rotation and translation of the autonomous mobile robot (AMR). The ANN will work as an iterative closed point, which is commonly used with the singular value decomposition algorithm. This development will provide better resolution for a relative positioning technique that is essential for the AMR localization. The ANN requires a specific architecture, although in the current work a neural architecture search will be adapted to select the best ANN for estimating the relative motion. At the end, these ANNs will be compared with conventional algorithms to check the good performance of adopting an intelligent method for relative positioning estimation.

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.

The text analyses how the use of certain expressions linked to Spanish Transition in political debate has served to demonstrate the extent to which confrontation over the legacies of that historical process forms part of an ideological conflict to this day. Two conceptual expressions, employed for different ends, serve to channel and concretize these proposals: the first is the regime of 78, while the other expression examined is the second transition. Analysis of the two expressions serves to confirm how the different ways of viewing the Transition have been pushing back the possibility in Spain of considering this process as one of those interpretations of the past on which nations are secured, providing citizens with a shared explanation of their present.
