En un artículo anterior expusimos el marco cristológico donde trata la Escolástica la ciencia humana de Jesucristo. Al asumir el Verbo la naturaleza humana de Jesús para llevar a cabo la redención, implica la consideración de la constitución ontológica del Hijo de Dios. Esto se analiza en la cuestión de la unión hipostática. La postura de la Escuela Franciscana arranca de Alejandro de Hales ante las tres opiniones que Pedro Lombardo transmite en las Sentencias. Por otra parte, esta cuestión conduce (...) al análisis de la esencia y propiedades de dicha naturaleza asumida. Con esto se contemplan, no sólo las cualidades naturales, por lo general situadas en el alma de Cristo, sino también los defectos aducidos en el estudio sobre la pasión y muerte de Cristo, centro de la aislada soteriología medieval.

A partir de las deficiencias detectadas en la evaluación de los objetivos educativos en la asignatura Morfofisiología I de la carrera de Estomatología, determinadas en un estudio previo realizado en la Facultad de Estomatología de Camagüey, se diseñó una metodología para facilitar a los docentes indicadores que les permitan considerar los objetivos educativos dentro de la evaluación final de los estudiantes. Se incluyen etapas, procedimientos y pasos para la instrumentación de la misma. Se considera que la misma facilitará un juicio (...) de valor más objetivo respecto al cumplimiento de los objetivos educativos. Starting from the analysis of the difficulties found in the evaluation of the educative objectives of the subject Morphophysiology I in the dental career, the findings were taken from a previous study carried out in the dental faculty in Camagüey a methodology was designed to give teacher's parameters to include the educative objectives within the final evaluation of the students. Stages, procedures and steps have to be followed to put it into practice. Its implementation is considered to give a better judgment in the fulfillment of the educative objectives. (shrink)

Se realizó un estudio descriptivo para identificar los procedimientos que utiliza el colectivo de Morfofisiología I de la carrera de Estomatología para evaluar los objetivos educativos de la asignatura. Conformaron el universo todos los estudiantes de primer año de la carrera del curso 2010-2011 y los profesores del colectivo de la asignatura de la Facultad de Estomatología de Camagüey. Se aplicaron encuestas a profesores y estudiantes y guías de observación a las diferentes formas de organización de la enseñanza. Los profesores (...) no aprovechan todas las formas de organización de la enseñanza para calificar los objetivos educativos y predominó el criterio de que se han formado mediante la observación del estudiante y el rendimiento académico al otorgar la nota final de la asignatura. La utilización de indicadores para la evaluación de los objetivos educativos en la asignatura puede constituir una herramienta que facilite este trabajo al colectivo. A descriptive study was done to identify the procedures used by the Morphophysiology I teaching staff of Dentistry in order to evaluate the educative objectives of this subject. The universe was made up of all the first year students in the 2010 - 2011 academic year as well as all the professors of Morphophysiology I in the Faculty of Dentistry in Camag|ey. Professors and students were surveyed. Observation guides were designed to assess the different ways of teaching organizations. The professors of this teaching staff do not take advantage of all the forms of teaching organizations in order to evaluate the educative objectives and the prevalent criterion was that these objectives are being formed by means of the students'observation and their academic efficiency. The use of indicators to evaluate the educative objectives in Morphophysiology I may serve as a tool that facilitates this work. (shrink)

Despite the salient experience of encoding threatening events, these memories are prone to distortions and often non-veridical from encoding to recall. Further, threat has been shown to preferentially disrupt the binding of event details and enhance goal-relevant information. While extensive work has characterised distinctive features of emotional memory, research has not fully explored the influence threat has on temporal memory, a process putatively supported by the binding of event details into a temporal context. Two primary competing hypotheses have been proposed; (...) that threat can impair or enhance temporal memory. We analysed two datasets to assess temporal memory for an in-person haunted house experience. In study 1, we examined the temporal structure of memory by characterising memory contiguity in free recall as a function of individual levels of heart rate as a proxy of threat. In study 2, we replicated marginal findings of threat-related increases in memory contiguity found in study 1. We extended these findings by showing threat-related increases in recency discriminations, an explicit test of temporal memory. Together, these findings demonstrate that threat enhances temporal memory regarding free recall structure and during explicit memory judgments. (shrink)

The scientific study of consciousness emerged as an organized field of research only a few decades ago. As empirical results have begun to enhance our understanding of consciousness, it is important to find out whether other factors, such as funding for consciousness research and status of consciousness scientists, provide a suitable environment for the field to grow and develop sustainably. We conducted an online survey on people’s views regarding various aspects of the scientific study of consciousness as a field of (...) research. 249 participants completed the survey, among which 80% were in academia, and around 40% were experts in consciousness research. Topics covered include the progress made by the field, funding for consciousness research, job opportunities for consciousness researchers, and the scientific rigor of the work done by researchers in the field. The majority of respondents (78%) indicated that scientific research on consciousness has been making progress. However, most participants perceived obtaining funding and getting a job in the field of consciousness research as more difficult than in other subfields of neuroscience. Overall, work done in consciousness research was perceived to be less rigorous than other neuroscience subfields, but this perceived lack of rigor was not related to the perceived difficulty in finding jobs and obtaining funding. Lastly, we found that, overall, the global workspace theory was perceived to be the most promising (around 28%), while most non-expert researchers (around 22% of non-experts) found the integrated information theory (IIT) most promising. We believe the survey results provide an interesting picture of current opinions from scientists and researchers about the progresses made and the challenges faced by consciousness research as an independent field. They will inspire collective reflection on the future directions regarding funding and job opportunities for the field. (shrink)

The aim of this article is to analyse the internal mechanisms of corporate governance (board of directors and ownership structure), which influence voluntary disclosure of intangibles. The results appear to corroborate the view that an increase in institutional investor shareholding has a negative effect on voluntary disclosure, supporting the hypothesis of entrenchment, whereas an excessive ownership by institutional investors may have adverse effects on strategic disclosure decisions. The results also indicate that an increase in the number of members of the (...) board to up to 15 has a beneficial effect on the disclosure of intangibles. However, as this number increases, the effect inverts and becomes adverse to improving the capacity for supervision and control in the decision-making process regarding the voluntary disclosure of intangibles. The findings endorse the recommendation of the most of the Corporate Governance Codes regarding an advisable maximum of 15 members on a board to ensure its effectiveness and internal cohesion.

A reality-design gap in the conceptualization and practice of digital agriculture has been systematically reported in the literature. This condition is favored by the lack of understanding and inclusion of local worldviews around digital technologies. Informed by Amartya Sen’s capabilities approach, this study looks to bring stories of local appropriation to the spotlight. Based on a qualitative approach that included data collected through interviews with 73 households, the authors explored the way in which two selected communities of Colombian coffee growers (...) are engaged in the use of digital technologies in material and symbolic ways. Three emergent themes—a relational way of farming, (dis)connected machines, and nurtured families and communities – articulate multiple interactions between farmers, farms, institutional programs, and technologies, that originate local forms of digitalization (and non-digitalization). This study points out the relevant role of situated ideas of development in positioning technologies in or out of the farm, and broader digitalization agendas in or out of farmers’ life projects. At the same time, it presents a critique of notions of universality that drive unquestioned quests for technification. In contrast, building on a relational perspective, this study calls for embracing a perspective of multiplicity within notions of development and innovation. (shrink)

Resumen El proyecto Es.Var.Atenuación se interesa por el estudio de la atenuación pragmática a nivel lingüístico, estructural, enunciativo y situacional, en corpus discursivos del español, a fin de reconocer las posibles estrategias atenuantes de un acto comunicativo. Para llevar a cabo el análisis se parte de una ficha de trabajo. Onomázein, 28, pp. 288–319; Albelda, Briz, Cestero, Kotwica y Villalba, 2014. Ficha metodológica para el análisis pragmático de la atenuación en corpus discursivos del español.. Oralia, 17, pp. 7–62) organizada en (...) cinco bloques de factores: funciones de la atenuación, procedimientos lingüísticos de la atenuación, factores estructurales, factores enunciativos y factores situacionales. A partir de esta ficha de trabajo, el propósito de nuestra investigación es considerar la implicación del componente fonoprosódico de la lengua, de modo que nos centramos en el segundo bloque de factores de la ficha indicada. Dicho bloque contiene 22 tácticas lingüísticas de atenuación; de ellas, la táctica 21 se refiere a los elementos prosódicos, paralingüísticos o gestuales y su papel en la expresión de atenuación. Esta táctica, no obstante, debe ser desarrollada para valorar mejor el peso de lo prosódico en la atenuación; se cuenta para ello con la experiencia previa del proyecto Fonocortesía, donde se manejan parámetros segmentales y suprasegmentales relevantes para la expresión de cortesía verbal. El objetivo de este trabajo es, en fin, desarrollar metodológicamente la descripción del componente prosódico en la actividad atenuadora, y precisar a través de parámetros acústicos objetivables en qué pueda consistir ese papel atenuante.

Feature selection is a widely studied technique whose goal is to reduce the dimensionality of the problem by removing irrelevant features. It has multiple benefits, such as improved efficacy, efficiency and interpretability of almost any type of machine learning model. Feature selection techniques may be divided into three main categories, depending on the process used to remove the features known as Filter, Wrapper and Embedded. Embedded methods are usually the preferred feature selection method that efficiently obtains a selection of the (...) most relevant features of the model. However, not all models support an embedded feature selection that forces the use of a different method, reducing the efficiency and reliability of the selection. Neural networks are an example of a model that does not support embedded feature selection. As neural networks have shown to provide remarkable results in multiple scenarios such as classification and regression, sometimes in an ensemble with a model that includes an embedded feature selection, we attempt to embed a feature selection process with a general-purpose methodology. In this work, we propose a novel general-purpose layer for neural networks that removes the influence of irrelevant features. The Feature-Aware Drop Layer is included at the top of the neural network and trained during the backpropagation process without any additional parameters. Our methodology is tested with 17 datasets for classification and regression tasks, including data from different fields such as Health, Economic and Environment, among others. The results show remarkable improvements compared to three different feature selection approaches, with reliable, efficient and effective results. (shrink)

In the philosophy of science, abstraction has usually been analyzed in terms of the interface between our experience and the design of our concepts. The often implicit assumption here is that such interface has a definite identifiable and universalizable structure, determining the epistemic correctness of any abstraction. Our claim is that, on the contrary, the epistemic grounding of abstraction should not be reduced to the structural norms of such interface but is also related to the constraints on the cognitive processes (...) of specific abstractions. This suggests that we should understand abstraction as embodied in different kinds of abstraction practices. (shrink)

This multiple-case study examined the rationales and instructional strategies for teaching history of science of 16 instructors of a history of science course for undergraduate preservice teachers in the USA. Based on instructor syllabi, instructional materials, and instructor interviews, we conducted single-case and cross-case analyses to identify why they teach HOS, how they teach HOS, and what possible relationships might underlie instructor rationales and their instructional strategy choices for teaching HOS. We found 10 rationales in three overarching categories and 9 (...) active-learning instructional strategies. Moreover, we found that instructors with skills rationales implemented active-learning instructional strategies, whereas instructors who only cited knowledge rationales relied only on lectures and reading discussions. We discuss implications and recommendations for the design of HOS courses. (shrink)

During the 19th century, evolutionary models of innovation followed a famous thesis of continuity, according to which methods and explanatory patterns of biology should have an important say in the social sciences. In the 20th century, this thesis was considered unacceptable as part of the sharp separation of biology from the social sciences. Recent advances in the biological sciences suggest a way in which a version of the thesis of continuity can be reinstated, to suggest new ways of explaining innovation (...) in the social sciences. Key kinds of innovation can be explained in terms of the evolution of robust complex systems, interpreted as processes of path creation. (shrink)

La filosofía de la ciencia se desarrolló durante la primera mitad del siglo xx bajo el supuesto de que la ciencia podía caracterizarse por la estructura lógica tanto del conocimiento articulado en las teorías más exitosas como de sus explicaciones. En la segunda mitad del siglo xx se cuestiona fuertemente esa idea, pero se sigue asumiendo que la filosofía de la ciencia debe hacerse siguiendo los cánones de una epistemología fundamentalista que considera que el avance de la ciencia pasa por (...) una ontología cada vez mas austera guiada por la idea de "mientras menos mejor". Desde esta perspectiva fundamentalista, el que las diferentes ciencias hablen de diferentes tipos de cosas es un obstáculo al entendimiento, producto de la imperfección del conocimiento actual. Este ideal nos invita a pensar que la epistemología debe hacerse reflexionando sobre el conocimiento articulado en nuestras teorías más austeras y nos compromete con propuestas reduccionistas problemáticas que no permiten explicar la diversidad de recursos epistémicos que de hecho utilizan los científicos. En este libro promovemos una epistemología que no sigue el lema de "mientras menos mejor", sino el de "organizar nuestros recursos epistémicos de manera que se genere entendimiento". Así, la misma estructura de las explicaciones y las prácticas (que incluye métodos y normas respecto de lo que se considera plausible y valioso) es lo que nos da la pauta para responder a la pregunta de qué es lo que hay. Esta estrategia epistémica nos obliga a hacer una filosofía de la ciencia muy cercana a la ciencia, reconociendo la pluralidad de sus métodos, objetivos y prácticas, sin reducir la filosofía de la ciencia a la sociología o a cualquier otra ciencia en particular.
