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)

Music can reduce stress and anxiety, enhance positive mood, and facilitate social bonding. However, little is known about the role of music and related personal or cultural variables in maintaining wellbeing during times of stress and social isolation as imposed by the COVID-19 crisis. In an online questionnaire, administered in 11 countries, participants rated the relevance of wellbeing goals during the pandemic, and the effectiveness of different activities in obtaining these goals. Music was found to be the most effective activity (...) for three out of five wellbeing goals: enjoyment, venting negative emotions, and self-connection. For diversion, music was equally good as entertainment, while it was second best to create a sense of togetherness, after socialization. This result was evident across different countries and gender, with minor effects of age on specific goals, and a clear effect of the importance of music in people's lives. Cultural effects were generally small and surfaced mainly in the use of music to obtain a sense of togetherness. Interestingly, culture moderated the use of negatively valenced and nostalgic music for those higher in distress. (shrink)

Aberrations introduced by the atmospheric turbulence in large telescopes are compensated using adaptive optics systems, where the use of deformable mirrors and multiple sensors relies on complex control systems. Recently, the development of larger scales of telescopes as the E-ELT or TMT has created a computational challenge due to the increasing complexity of the new adaptive optics systems. The Complex Atmospheric Reconstructor based on Machine Learning is an algorithm based on artificial neural networks, designed to compensate the atmospheric turbulence. During (...) recent years, the use of GPUs has been proved to be a great solution to speed up the learning process of neural networks, and different frameworks have been created to ease their development. The implementation of CARMEN in different Multi-GPU frameworks is presented in this paper, along with its development in a language originally developed for GPU, like CUDA. This implementation offers the best response for all the presented cases, although its advantage of using more than one GPU occurs only in large networks. (shrink)

Is the societal-level of analysis sufficient today to understand the values of those in the global workforce? Or are individual-level analyses more appropriate for assessing the influence of values on ethical behaviors across country workforces? Using multi-level analyses for a 48-society sample, we test the utility of both the societal-level and individual-level dimensions of collectivism and individualism values for predicting ethical behaviors of business professionals. Our values-based behavioral analysis indicates that values at the individual-level make a more significant contribution to (...) explaining variance in ethical behaviors than do values at the societal-level. Implicitly, our findings question the soundness of using societal-level values measures. Implications for international business research are discussed. (shrink)

Interest in ethical aspects associated to product acquisition and consumption is a growing trend among consumers. In this context, the concept of “product with ethical attributes” has arisen to refer to products with explicit social and environmental characteristics. However, one of the factors that most hinders the purchasing of these products is certainly price. Given the difficulty of reducing price, the question that arises is the extent to which other product attributes can attenuate the negative impact of price on perceived (...) value. We assume that the special benefits associated to this type of products are, at a different level, attenuators of the relationship between price and perceived value. Focusing on Fair Trade organic coffee, hypotheses are tested regarding survey data from 407 customers. They were interviewed in an actual purchasing scenario. The models are tested using conventional Structural Equation Models and the Latent Moderated Structural Equation method. The results obtained shed some light on a highly generalised belief that the marketing of these products can only be improved by reducing their price. However, although a price reduction could be desirable, albeit complicated in this product category, its effects could be reduced by acting on other variables such as the ethical aspects, quality and healthiness of this product category.

Background: Serious games have shown positive results in increasing motivation, adherence to treatment and strengthening the therapeutic alliance in multiple psychiatric disorders. In particular, patients with impulse control disorders and other disorders in which the patient suffers from inhibitory control deficits have been shown to benefit from serious games.Aim: The aim of this study was to describe the characteristics and to evaluate the usability of a new serious videogame, e-Estesia. This serious videogame was designed to improve emotion regulation in patients (...) with gambling disorder. Preliminary results from a pilot sample are also reported.Method: A pilot sample of 26 patients undergoing treatment for GD was recruited. Participants used e-Estesia on a tablet, which was connected to a thoracic band that sent heart rate and heart rate variability data to the videogame platform in order to provide biofeedback. The System Usability Scale was completed by patients to determine the usability of e-Estesia.Results and Discussion: e-Estesia performed comparatively well for all the explored groups. Around 84.6% of the patients endorsed that it was easy to use. Female patients with GD presented higher HRV during the use of the serious videogame compared to men. (shrink)

Diabetes has been associated with affective disorders which complicate the management of the disease. Emotional intelligence, or the ability to perceive, facilitate, understand, and regulate emotions, has shown to be a protective factor of emotional disorders in general population. The main objective of this study was to systematically review the role of the EI construct in Type 1 and Type 2 diabetics and to observe how EI is related to biological and psychological variables. Comprehensive searches were conducted in PubMed, Scopus, (...) PsycInfo, and Cochrane without time limitations, for studies examining the link between diabetes and EI. A total of 12 eligible studies were selected according to the inclusion criteria. We divided the results into four sections: EI and hemoglobin glycosylated, EI training effects, differences in EI between persons with diabetes and without diabetes, and EI and psychological adjustment and well-being. The results showed negative correlations between EI and HbA1c, positive effects of EI training on quality of life, anxiety, and glycemic control, no differences in EI between people with diabetes and healthy individuals, and, finally, negative correlations between EI and different psychological variables such as diabetes-related anxiety and distress, and positive correlations with quality of life, well-being, and marital satisfaction. This systematic review offers a starting point for a theoretical and practical understanding of the role played by EI in the management of diabetes and reveals that EI is a promising protective factor for biological and psychological variables in this population.

In this paper I will argue that when Aristotle uses the word ‘ἀρχή’ he is often referring to what we call a condition, whether necessary, sufficient or necessary and sufficient. To this end I will discuss how conditions for being, change, and knowledge, as identified by Aristotle, can be equated to ontological, physical and noetic principles, respectively.

In this paper, I argue that the certainty about the wrongness of killing must not be considered as a universal, but as a local one. Initially, I show that there exist communities in which the wrongness of killing innocents is not a moral certainty and that this kind of case cannot be justified by arguing that such people are psychopaths. Lastly, I argue that universal certainties do not admit of exceptions: thus, the fact that some exceptional cases affect the certainty (...) that killing innocents is wrong, leads me to conclude that it is a local certainty.

Resumen: En las Disputationes Metaphysicae XIII, X-XIV Francisco Suárez expone su parecer sobre la incorruptibilidad de los cielos. Particularmente, la sección XI, 13-34 reviste capital importancia de acuerdo con un tópico contextual: la incipiente revolución copernicana y el quebrantamiento de las tesis fundamentales aristotélicas. Su confutación, ubicada principalmente en las D.M. XIII, XI, 13, constituye la piedra angular que le permitirá al Dr. Eximio continuar sosteniendo una posición metafísica-cosmológica de cuño aristotelizante.

Educar es alumbrar, es ayudar al crecimiento de lo más humano del ser humano; educar es confiar, la confianza no es permisiva, implica acoger a la persona en su integridad; educar es pedir, los papás lo saben bien, ellos, así como de otra manera los maestros, igualmente reciben otro don, que les ayuda a madurar como padres y maestros; educar es sembrar, lo esencial del crecimiento es cualitativo, mientras que el enriquecimiento en la dimensión del poseer se da tan solo (...) por acumulación; educar es alentar, el definitivo logro dependerá de los hábitos virtuosos con los que cada persona provea las alforjas para recorrer su itinerario biográfico.

Literature on indoctrination has focused on imparting and revising beliefs, but it has hardly considered the way of teaching and acquiring certainties—in Wittgenstein’s sense. Therefore, the role played by rationality in the acquisition of our linguistic practices has been overestimated. Furthermore, analyses of the relationship between certainty and indoctrination contain major errors. In this paper, the clarification of the aforementioned issues leads me to suggest the avoidance of the term ‘indoctrination’ so as to avoid focusing on the suitability of the (...) case to the concept rather than on the analysis of the case itself. This should facilitate that the process of helping children to acquire a world-picture—by teaching them to ignore alternatives to certainties—is definitely accepted as normal and natural, for many beliefs are expected to end up becoming ungrounded certainties not only in the medium or long term, but also, and above all, in the short term.

After describing Wittgenstein's notion of ‘certainty’, in this article I provide four arguments to demonstrate that no certainty can be acquired at will. Specifically, I argue that, in order to assimilate a certainty, it is irrelevant whether the individual concerned has found a ground that seemingly justifies that certainty; has a given mental state; is willing to accept the certainty on the proposal of a persuader; or tries to act according to the certainty involved. Lastly, I analyse how each of (...) these arguments is reflected in the way children acquire certainties. (shrink)

It is expected that children increasingly learn to identify errors throughout their schooling process and even before it. As a further step, however, some scholars have suggested how a culture of error should be implemented in the classroom for the student to be able not only to locate errors but also, and above all, to learn from them. Yet the various proposals aimed at generating a culture of error in the classroom keep regarding error as all those responses and reactions (...) that are not considered as true or correct in each specific case, thereby not realizing that many of these alleged errors are really anomalies with very different characteristics and consequences despite their seeming resemblance. In this paper, I rely on Ludwig Wittgenstein’s On Certainty to clarify the difference between errors and anomalies. Subsequently, I provide guidelines that may be adapted by each teacher to her students’ needs and development level in order to foster a culture of error that begins by distinguishing er... (shrink)

Wittgenstein scholars have tended to interpret the acquisition of certainties, and by extension, of a world-picture, as the achievement of a state in which these certainties are assimilated in a seemingly unconscious way as one masters language-games. However, it has not been stressed that the attainment of this state often involves facing a series of challenges or difficulties which must be overcome for the development of the world-picture and therefore the socialization process to be achieved. After showing, on the one (...) hand, how a world-picture is usually developed, and on the other hand, why a child who seemingly found itself trapped in a precocious skepticism might have serious problems in assimilating certainties, in this paper, I describe some of the challenges children often meet as they acquire a world-picture. Since the overcoming of these challenges is often needed for children to develop a world-picture, I aim at raising the awareness of the necessity of ‘learning to believe’, that is, of developing a series of skills that allow children to undertake the challenges described in this paper.

The "transcendental freedom" is proper of the personal being, free and intelligent. This key concept of Heidegger ("transzendentalen Freiheit") is reelaborated by Millán-Puelles with Thomas Aquinas' contributions, mainly Aquinas' theory on the properties of transcendental being ("ens transcendentale"). This reelaboration is relevant for the discussion about the importance of educational paradigms. A human person is something "open" to the being and value and consequently, to educate is to communicate values through personal paradigms.

In this paper, we explore a selection of Castoriadis’ writings, paying special attention to the seminars devoted to Plato’s Statesman, and discuss his divorce from the Platonic and Platonic tradition. Castoriadis places Plato beyond a theoretical and academic interpretation: the Ancient Greece that Castoriadis claims, from his political ontology, is not a paradigm, but a “germ” of autonomy, by which understand the birth of democracy, philosophy and history in order to transform himself and society.

Though Wittgenstein's On Certainty has been influential in analytic epistemology, its interpretation has been enormously controversial. It is true that exegesis has been mainly concerned with the proper characterization of Wittgenstein's very notion of ?certainty?; however, some important questions remain unanswered regarding this notion. On the one hand, I am above all referring to the study of the possibilities we have of retaining a certainty when it has seemingly been placed into question and, on the other hand, of regaining a (...) certainty once it has been lost. In this paper, I attempt to provide a detailed answer to both questions. In so doing, some important features of the picture of ourselves which emerges from Wittgenstein's On Certainty are also revealed. (shrink)

Algunos autores han intentado considerar los delirios como certezas –entendidas en el sentido de Wittgenstein– debido a las similitudes que parecen existir entre sus respectivos estatus epistemológicos. Sin embargo, dicho intento ha sido criticado con agudeza, entre otras razones, porque el contenido de los delirios choca frontalmente con el contenido de las certezas, por lo que los delirios no pueden ser comprendidos debido a los cambios en las relaciones de significado. Pero es evidente que, aunque los delirios no se puedan (...) contemplar como certezas, muchos delirios afectan de un modo u otro al sistema de certezas del paciente. Partiendo de esta base, no es descabellado pensar que dicha influencia pudiera ser también recíproca: en otras palabras, parece sumamente recomendable analizar si algunos delirios se podrían contemplar como el resultado de variaciones en certezas. En este artículo llevo a cabo dicho análisis al intentar mostrar que el origen de algunos delirios pedestres y severos puede ser hallado en lo que llamaré “ceguera a posibilidades” e “incertidumbre”, términos que he desarrollado teniendo en cuenta la obra del filósofo Ludwig Wittgenstein.

This paper presents the concept of ‘religious certainty’ I have developed by drawing inspiration from Wittgenstein’s notion of ‘certainty’. After describing the particular traits of religious certainty, this paper addresses two difficulties derived from this concept. On the one hand, it explains why religious certainty functions as such even though all its consequences are far from being absolutely clear; on the other hand, it clarifies why, unlike the rest of certainties, the loss of religious certainty does not result in the (...) collapse of the world-picture made up of all certainties. Subsequently, it analyzes to what extent the teacher can teach religious certainty by acting as a facilitator for its acquisition–if desired—particularly bearing in mind that religious certainty cannot be attained at will. These basic teaching guidelines have several advantages. First, they make it possible to know the nature of religious certainty even better. Second, and most importantly, the fact of having adopted the perspective of a teacher who tries inculcating a religious certainty contributes to detecting and preventing forms of indoctrination that, arguably, might go unnoticed even when attempting to properly present religious certainty—or rather, this way of being religious—in current schools to foster understanding thereof.

In this paper, I describe the main lines of modern error theory, a systemic theory which regards errors not as the results of someone’s negligence, but as parts of a complex system. Bearing in mind that errors must be considered as such by an observer or attributor, I expose Wittgenstein’s conception of the attributor responsible for discerning if a strange event constitutes an error or an anomaly. Subsequently, I illustrate this conception of the attributor by describing some traits of the (...) role played by many attributors in business organizations, specifically in the production line of a car manufacturer’s plant, when carrying out the rootcause analysis of problems that arise in the plant. Finally, I reveal a paradox whereby if the attributor denies the possibility that anomalies may happen without being able to explain their source within the system that he or she takes as reference, then the very idea of system no longer makes sense.

Wittgenstein’s conception of ‘persuasion’, understood as the persuader’s attempt to modify the persuadee’s certainties, has been recently misinterpreted by some scholars. For Persichetti has overlooked the fact that one cannot persuade unintentionally, while Marconi and Perissinotto have not only taken for granted that persuasion consists in the mere transfer of a world-picture or set of certainties to an individual even when she has not alternative or different certainties, but also that education is restricted to persuading or transmitting certainties. After clarifying (...) these misinterpretations, among others, I argue that persuasion is not used for teaching certainties at the outset, but for modifying them when they do not fit the ones expected by the persuader. If it is agreed that education partly consists in transmitting a world-picture, then persuasion constitutes a necessary resource for educators. Lastly, I provide a set of guidelines for teachers to draw attention to the basic aspects of persuasion that they should consider in the classroom. (shrink)

In this paper I outline the most relevant traits of the term ‘trust’ understood as one of the synonyms for ‘certainty’ that Ludwig Wittgenstein used in his posthumous work On Certainty. To this end, I analyze the paragraphs of On Certainty in which reference is made to pupils who are expected to trust what is taught by their teacher: in addition, I note that such a process is largely based on the attitude of rejection and bewilderment that teachers promote towards (...) people who call into doubt those certainties that pupils are expected to assimilate. Subsequently, after emphasizing the importance that Wittgenstein attached to the ineffability of certainties, I explain how such certainty or trust can be staged. Lastly, I clarify why an appropriate contemplation of this staging can be of great help for pupils to achieve at least four goals of educational interest: thus, children can not only strengthen their capacity for wonder, but also experience what things are ineffable, glimpse the limits of rationality, and become more tolerant of people who are partakers of a different world-picture.
