Rationale, aims and objectives Given the increasing prevalence of cataract and demand for cataract extraction surgery, patients must often wait to undergo this procedure. We validated a previously developed priority scoring system in terms of clinical variables, pre-intervention health status, appropriateness of surgery and gain in visual acuity (VA) and health-related quality of life (HRQoL).Methods Explicit prioritization criteria for cataract extraction created by a variation of the Research and Development (RAND) and University of California Los Angeles appropriateness methodology were retrospectively (...) applied to a prospective cohort of 5257 patients on waiting lists to undergo cataract by phacoemulsification at 17 hospitals in Spain. Demographic data, clinical data and data related to surgical technique were collected by trained ophthalmologists. Patients were evaluated by their ophthalmologist before the intervention and 6 weeks afterward. They also completed, by mail, the Visual Function Index (VF-14) before the intervention and 3 months afterward.Results High-priority patients experienced greater improvement in VA and HRQoL than those classified as intermediate or low-priority (P < 0.0001), even after adjusting by VA and the VF-14 score at baseline. The time to intervention was the same for high-priority patients as it was for intermediate and low-priority patients.Conclusions The priority score we developed identified patients most likely to experience the greatest improvements from cataract extraction. Use of this tool could provide a fairer and more rational way to prioritize patients for cataract extraction. (shrink)

In this paper, I respond to what I have called an epistemological objection to a dialetheist approach to the doctrine of the Incarnation, of which one example is Beall’s contradictory Christ. I discuss Anderson’s book Paradox in Christian theology, in which the author claims to account for the rationality of the doctrine of the Incarnation as a merely apparently contradictory doctrine, and I present my model, based on Anderson’s model, according to which the doctrine has the possibility to be rational (...) by understanding it as genuinely contradictory. I show that this model fits perfectly well with the criteria that, according to Anderson, any model for the rationality of a paradoxical doctrine should meet. Beall does not address the problem of the rationality of the doctrine in his works about the contradictory Christ, and he asserts that he is not interested in it. However, I think that if he wants to make his theory more robust, less suspicious, and more convincing for theologians, philosophers, and ordinary people, he should consider this problem. (shrink)

Considering the transformation of educational scenarios, we recognize the need to train foreign language teachers with high pedagogical, research, and technological skills. This recognition considers the new challenges of education and aligns with the educational discourses and commitments that are shaped by the curricular proposals of foreign language programs in higher education. It is necessary to know the level of competencies of teacher trainers, university lecturers, to identify possible ongoing training needs. This research uses a mixed-methods design with an exploratory-descriptive (...) approach that contributes to the educational instructions to start continuous training plans for their teachers under the policies, global dynamics, and demands of education. The research shows that there are still challenges to confront, as teachers still have opportunities to strengthen their pedagogical, educational, and new technology competencies. This is a challenge that institutions should address in the rigorous implementation of lifelong learning programs. (shrink)

En este escrito, 1) hago una presentación del tipo de análisis conceptual quehace Wittgenstein en algunas obras posteriores al Tractaus; me refiero,específicamente, a una cierta manera de proceder que consiste en ladescripción de los diferentes usos de un concepto, y que tiene como finarrojar luz sobre las condiciones de funcionamiento de nuestro lenguaje para,así, llegar a la solución de un determinado problema filosófico. 2) Examinoalgunos pasajes de las Investigaciones en los que que Wittgenstein analizaconceptos psicológicos y señalo lo que considero (...) son algunas fallas de lasinterpretaciones naturalistas, externalistas y mentalistas de esos pasajes. 3)Presento una interpretación de la perspectiva de Wittgenstein en torno alproblema de la existencia y naturaleza de los estados y procesos psicológicos,que tiene en cuenta, tanto el tipo de análisis que Wittgenstein hace, comoalgunas afirmaciones suyas extraídas de las Investigaciones y de LosCuadernos Azul y Marrón.

In this paper I examine the conflicting ways in which Bertrand Russell and Hegel understand indexical expressions. For this purpose, I consider some books and articles written by Russell in different moments of his life, and the first chapter of Hegel’s Phenomenology of Spirit, book published in 1807. I try to show that Russell, even being a Hegel scholar, does not respond to his proposal about indexical expressions, but takes a position that keeps him trapped in a kind of self-deception (...) of sense-certainty. At the end, I suggest that the differences between Hegel and Russell in relation to indexical expressions can be explained by the fact that the ontologies adopted by both authors exclude each other.

La obtención de alimentos sanos y seguros requiere de técnicas de conservación inocuas para el consumidor y para el me­dio ambiente, entre las que se destaca la bioconservación. A su ca­tálogo de compuestos naturales o microorganismos, utilizados de forma habitual, la bioconservación ha incorporado recientemente los bacteriófagos y las proteínas fágicas con actividad lítica. La utilización de fagos y endolisinas en el biocontrol ofrece importantes ventajas frente a otros sistemas de conserva­ción tradicionales. Entre dichas ventajas destacan su inocuidad, especificidad y (...) versatilidad. Por otra parte, la acuciante necesidad de reducir el uso de antibióticos en la cadena alimentaria ha impul­sado la investigación basada en estos antimicrobianos con el fin de aplicarlos en producción primaria. Sin embargo, y a pesar de la gran eficacia ya demostrada en múltiples sectores, la falta de legislación de la Unión Europea sobre el uso de bacteriófa­gos junto con la necesidad de ser aceptados por los consumidores, son factores que están afectando negativamente a su implantación como bioconservantes. En este contexto, este artículo recoge los últimos resultados relacionados con este tipo de antimicrobianos en la industria agro-alimentaria, y resume los puntos clave para entender las posibilidades reales de su aplicación ante los nuevos requisitos asociados con una producción sostenible tanto desde una perspectiva económica como ambiental.

ABSTRACTPrior research has found a relationship between perceived facial attractiveness and perceived personal trustworthiness. We examined the time course of attractiveness relative to trustworthiness evaluation of emotional and neutral faces. This served to explore whether attractiveness might be used as an easily accessible cue and a quick shortcut for judging trustworthiness. Detection thresholds and judgment latencies as a function of expressive intensity were measured. Significant correlations between attractiveness and trustworthiness consistently held for six emotional expressions at four intensities, and neutral (...) faces. Importantly, perceived attractiveness preceded perceived trustworthiness, with lower detection thresholds and shorter decision latencies. This reveals a time course advantage for attractiveness, and suggests that earlier attractiveness impressions could bias trustworthiness inferences. A heuristic cognitive mechanism is hypothesised to ease processing demands by relying on simple a... (shrink)

The origin of chordates and the consequent genesis of vertebrates were major events in natural history. The amphioxus (lancelet) is now recognised as the closest extant relative to the stem chordate and is the only living invertebrate that retains a vertebrate‐like development and body plan through its lifespan, despite more than 500 million years of independent evolution from the stem vertebrate. The inspiring data coming from its recently sequenced genome confirms that amphioxus has a prototypical chordate genome with respect to (...) gene content and structure, and even chromosomal organisation. Pushed by joint efforts of amphioxus researchers, amphioxus is now entering a new era, namely its maturation as a laboratory model, through the availability of a large amount of molecular data and the advent of experimental manipulation of the embryo. These two facts may well serve to illuminate the hidden secrets of the genetic changes that generated, among other vertebrates, ourselves. (shrink)

This paper presents a systematic investigation of fuzzy Galois connections in the sense of R. Bělohlávek [1], from the point of view of enriched category theory. The results obtained show that the theory of enriched categories makes it possible to present the theory of fuzzy Galois connections in a succinct way; and more importantly, it provides a useful method to express and to study the link and the difference between the commutative and the non-commutative worlds.

Processing data streams arriving at high speed requires the development of models that can provide fast and accurate predictions. Although deep neural networks are the state-of-the-art for many machine learning tasks, their performance in real-time data streaming scenarios is a research area that has not yet been fully addressed. Nevertheless, much effort has been put into the adaption of complex deep learning (DL) models to streaming tasks by reducing the processing time. The design of the asynchronous dual-pipeline DL framework allows (...) making predictions of incoming instances and updating the model simultaneously, using two separate layers. The aim of this work is to assess the performance of different types of DL architectures for data streaming classification using this framework. We evaluate models such as multi-layer perceptrons, recurrent, convolutional and temporal convolutional neural networks over several time series datasets that are simulated as streams at different speeds. In addition, we evaluate how the different architectures react to concept drifts typically found in evolving data streams. The obtained results indicate that convolutional architectures achieve a higher performance in terms of accuracy and efficiency, but are also the most sensitive to concept drifts. (shrink)

Inception module is one of the most used variants in convolutional neural networks. It has a large portfolio of success cases in computer vision. In the past years, diverse inception flavours, differing in the number of branches, the size and the number of the kernels, have appeared in the scientific literature. They are proposed based on the expertise of the practitioners without any optimization process. In this work, an implementation of population-based incremental learning is proposed for automatic optimization of the (...) hyperparameters of the inception module. This hyperparameters optimization undertakes classification of the MNIST database of handwritten digit images. This problem is widely used as a benchmark in classification, and therefore, the learned best configurations for the Inception module will be of wide use in the deep learning community. In order to reduce the carbon footprint of the optimization process, policies for reducing the redundant evaluations have been undertaken. As a consequence of this work, an evaluation of configurations of the inception module and a mechanism for optimizing hyperparameters in deep learning architectures are stated. (shrink)

En este trabajo se explora una conexión entre el contextualismo y el fiabilismo. El propósito es desarrollar las líneas centrales de un acercamiento contextualista para resolver la crítica internista de que las nociones fiabilistas de justificación y de conocimiento no son adecuadas porque no recogen las intuiciones correspondientes a que un sujeto que está justificado o que sabe es racional y epistemológicamente responsable. Se argumenta que esta crítica y el escepticismo pirrónico comparten un presupuesto común, a saber, la cláusula internista, (...) por lo que, si es posible limitar el alcance de esta cláusula a través del contextualismo distinguiendo dos contextos diferentes, entonces también es posible hacer uso de esta distinción para dar respuesta a la crítica internista al fiabilismo. In this paper, we explore a connection between reliabilism and contextualism. our purpose is to draw up a contextualist approach to solve the critique that the reliabilist notions of justification and knowledge are not satisfactory because there is no room for the intuitions that a subject who is justified or knows is rational and epistemologically responsible. We will argue that this critique and the Pyrrohnian skepticism share the same assumption, viz., the internalist clause. Thus, if it is possible to limit the scope of this clause using contextualism, making a distinction between two different contexts, then it is also possible to use this distinction to offer an answer to the internalist critique to reliabilism.

The impact of digital devices and the Internet has generated various changes at social, political, and economic levels, the repercussion of which is a great challenge characterized by the changing and globalized nature of today's society. This demands the development of new skills and new learning models in relation to information and communication technologies. Universities must respond to these social demands in the training of their future professionals. This paper aims to analyze the empirical evidence provided by international studies in (...) the last eleven years, related to the digital literacy of university students, including those pursuing degrees related to the field of education. Our findings highlight the fact that the digital literacy that is offered in universities to graduate/postgraduate students, in addition to treating digital literacy as a central theme, also focuses on perceived and developed self-efficacy. This is done by strengthening competencies related to digital writing and reading, the use of databases, the digital design of content and materials, and the skills to edit, publish or share them on the web, or applications aimed at treating digital literacy as emerging pedagogies and educational innovation. Secondly, we found studies related to digital competencies and use of the Internet, social networks, web 2.0, or the treatment of digital risks and their relationship with digital literacy. Thirdly, we found works that, in addition to focusing on digital literacy, also focused on different psychological constructs such as motivation, commitment, attitudes, or satisfaction.Systematic review registration:https://www.scopus.com/home.uri; https://www.recursoscientificos.fecyt.es/.

Cacao cultivation is one of the most important livelihoods for rural households in Colombia, where it is promoted as a substitute for the illegal cultivation of coca. To strengthen Colombian cacao farming, it is important to understand the livelihood strategies associated with cacao cultivation and the impact of these different strategies on the well-being of Colombian rural households. We analyzed the impact of cacao cultivation on the livelihood strategies and well-being of rural households in western Colombia. Research with 92 rural (...) cacao-growing households produced a typology of household livelihood strategies derived from their approach to cacao production. Indicators of each household capital and level of well-being were identified for each type of households. Correlations between the capitals and the capitals of greater importance in shaping the well-being of rural households were analyzed. Three types of rural households were identified: Cacao Farmers, Diversified Farmers with Cacao, and New Cacao Farmers. Cacao farmers have the highest capitals endowments and level of well-being, followed by Diversified Farmers with Cacao, and New Cacao Farmers. The conditions of cacao cultivation in rural households result in differentiated access to resources from capitals; households with better development of the crop have consolidated greater well-being where human capital has been its major driving factor. Success of the cacao crop and its relationship with well-being of rural households depends on the convergence of different capital resources. Thus, institutional efforts to strengthen the cacao sector in Colombia must go beyond investment to establish new hectares and consider aspects such as: Strengthening the skills and knowledge of producers to improve crop management practices, Promoting the participation of household members in associations, Stimulating sensitivity to the rooting and sustainable management of the crop, and Promoting processes of technification and adaptation of the infrastructure of fermenters and dryers, which will make it possible to guarantee an adequate quality of the cacao bean.

The concept of well-being of rural families is part of a theory under construction in which new theoretical elements are constantly being incorporated. This research aims to determine the influence of farmers’ knowledge on the well‑being of cocoa growing families in the departments of Santander, Huila, Meta and Caquetá, Colombia. Four categories of farmers were identified with different levels of knowledge in the management of cocoa cultivation obtained through a cluster analysis. The well-being of cocoa farmers, understood as the balance (...) in the capital endowment of rural households, was obtained through the application of a semi-structured interview with 49 variables of human, cultural, social, political, natural, built, and financial capitals. The results show that cocoa knowledge is heterogeneous in the study area, with a slight improvement towards harvesting, post-harvest and transformation links. There is a positive relationship between cocoa knowledge and the well-being of cocoa farming families. Thus, producers with greater integral knowledge, with emphasis on post-harvest and bean transformation links, showed greater well-being. The Random Forest analysis identified that human capital (political, social, human, and cultural) made the greatest contribution to well-being. The findings show that cocoa knowledge contributes to the well-being of rural households to the extent that it favors vertical relationships (linkages with local governments) and horizontal relationships of producers (participation of association managers, sharing knowledge with friends, neighbors and partners, and cocoa training).
