Con objetivo de comparar la autoeficacia y el desempeño en estadística de universitarios, previo y posterior a un curso de estadística tradicional y uno bajo la metodología de solución de problemas, se llevó a cabo un estudio cuasiexperimental de dos grupos intactos de 84 y 115 estudiantes de psicología, respectivamente, aplicando un test de fuentes de autoeficacia en estadística como pre y postest, un examen de matemáticas previo al curso y un examen de estadística luego del curso. Los resultados mostraron (...) diferencia significativa en el desempeño en estadística posterior al curso, siendo el grupo experimental el que tuvo mejores resultados. (shrink)

Background:The decision whether to initiate cardiopulmonary resuscitation may sometimes be ethically complex. While studies have addressed some of these issues, along with the role of nurses in cardiopulmonary resuscitation, most have not considered the importance of nurses acting as advocates for their patients with respect to cardiopulmonary resuscitation.Research objective:To explore what the nurse’s advocacy role is in cardiopulmonary resuscitation from the perspective of patients, relatives, and health professionals in the Basque Country (Spain).Research design:An exploratory critical qualitative study was conducted from (...) October 2015 to March 2016. Thematic analysis was used to analyse the data.Participants:Four discussion groups were held: one with patients and relatives (n = 8), two with nurses (n = 7 and n = 6, respectively), and one with physicians (n = 5).Ethical considerations:Approval was obtained from the Basque Country Clinical Research Ethics Committee.Findings:Three significant themes were identified: (a) accompanying patients during end of life in a context of medical dominance, (b) maintaining the pact of silence, and (c) yielding to legal uncertainty and concerns.Discussion:The values and beliefs of the actors involved, as well as pre-established social and institutional rules reduced nurses’ advocacy to that of intermediaries between the physician and the family within the hospital environment. On the contrary, in primary health care, nurses participated more actively within the interdisciplinary team.Conclusion:This study provides key information for the improvement and empowerment for ethical nursing practice in a cardiac arrest, and provides the perspective of patients and relatives, nurses and physicians.

El presente artículo pretende analizar los efectos transformadores que la pandemia por Covid-19 ha obrado en nuestras existencias individuales y en nuestra convivencia social cotidiana desde la propuesta analítica del filósofo surcoreano Byung Chul-Han. Dicha transformación es de tal profundidad que, para nuestro autor, viene a exacerbar los males de la sociedad contemporánea, como el agotamiento y el cansancio por autoexplotación y permanente optimización de sí mismo propiciados por el neoliberalismo globalizado y omnipresente en Occidente. Desde esta constatación analizaremos en (...) particular cómo la prevalencia de la comunicación digital obligada por la emergencia viral trae consecuencias antropológicas que amenazan con eliminar lo esencial de la vida humana: la construcción de rituales, la estructura temporal cotidiana, el contacto corporal con los demás, la pertenencia a una comunidad y la apreciación de lo real en su genuina dimensión ontológica. Finalmente, exploraremos una posible salida a la alienación virtual en que forzadamente se encuentra la sociedad contemporánea. (shrink)

Schools are an essential part of students’ lives and can promote and facilitate their well-being. Although research on well-being among school-aged children and adolescents has distinguished subjective well-being from social well-being, very few studies examined student’s social well-being at school. SWS is understood as students’ valuation of the circumstances and functioning of their school. This framework posits that the context of the schools can shape students’ perception of feeling integrated and making significant contributions to their schools. However, not much is (...) known regarding the joint contribution of individual, family, and school characteristics to students’ SWS. This study analyzed these joint contributions in a nationally representative sample of 6,389 children and adolescents enrolled in 5th–11th grades. Findings show that being female and younger were individual predictors of SWS. Students’ satisfaction with their family and fewer changes of schools were also significant contributors. When students’ perceptions of their schools were incorporated, the individual and family characteristics decreased or lost significance. In the full model, the highest contribution to SWS was explained by the school-level aggregated perception of school climate. These findings call for integrated policies and practices to foster students’ sense of belonging, feeling integrated, and contribution to their schools, with a focus on school-level interventions to improve SWS through positive and engaging school climates that foster students’ sense of agency.

School achievement and failure have become growing political and social concerns due to the negative consequences of school failure for individuals and society. The inclusive educational movement, which calls for equal access, permanence, participation, and promotion of all students worldwide, poses many challenges for schools and school systems. As a public policy strategy, some countries have provided additional funds for incorporating non-teaching professionals such as school psychologists and social workers in regular K-12 schools. However, there is lack of research on (...) the effects of these psychosocial professionals on student outcomes. This national multilevel study explored the effect of psychologists (n= 8,469) and social workers (n= 3,524) on indicators of eighth-grade (n= 147,531) and 10th-grade (n= 106,347) students' academic achievement and dropout in Chile. A multilevel secondary analysis was performed using national records of non-teaching professionals working as school staff members, achievement scores on the national SIMCE test, and dropout rates based on official records. Results showed that after controlling for individual and school variables known to affect achievement and dropout, schools with psychologists and social workers working as staff members had lower short- and long-term dropout rates. The presence and higher number of school psychologists per school was positively associated with higher math achievement, with a reduced effect in low-SES schools. Lower-SES schools with more social workers had higher math scores. These results support policies that increase funding for school psychologists and social workers, since their incorporation partly explains better school achievement and less school failure when controlling for individual and school characteristics, but emphasize the need to further explore the mechanisms through which school achievement and failure are developed with the support of psychologists and social workers in schools. We discuss the need to regulate the type of prevention and intervention strategies from a whole-school, evidence-based approach, as well as to incorporate psychosocial training modules and comprehensive guidelines as part of professional training programs and as certified requisites for working in schools.

El siguiente artículo examina la noción de resistencia elaborando un análisis que problematiza el lugar de la representación en política y en democracia. En un primer momento, se plantea el problema a partir de un relato que narra un episodio y un gesto especiales de algunos prisioneros liberados de un campo de concentración. Desde esta cuestión, se revisan las aportaciones de Michel Foucault relativas a la resistencia que dan como resultado, en definitiva, un desacople de las relaciones entre poder y (...) política. Así, la resistencia sugiere un vínculo con la política que no se restringe a las formas ni a los códigos de la política convencional. No obstante, las mismas aportaciones de Foucault plantean la cuestión de la libertad como una suerte de mandato para el sujeto, frente al cual la resistencia corre el riesgo de quedar atrapada. La figura de Bartleby (Melville) ofrecerá la ocasión para sugerir una hipótesis que permita indagar en torno a una resistencia radical que no se vea coaccionada por el privilegio de la representación. Posteriormente, se examinan las aportaciones de Jacques Derrida y su lectura del inquietante personaje de Melville, que posibilitan una puesta en cuestión de la publicidad irrestricta supuesta en los dominios de lo político, la política y la democracia como democracia representativa, e incluso una interrogación exigente de tales conceptos heredados. Frente al canon, Derrida permitirá pensar justamente una resistencia radical a la manera de cierto secreto que, diciéndose, no obstante, se sustrae de la representación, y que entonces será irreductible a los dominios de lo público-político, lo que no querrá decir que ese secreto se restrinja a lo privado y posibilite replantear la cuestión democrática. Finalmente, se presentan algunas conclusiones tentativas y una síntesis de aquellos desafíos que quedan anunciados. (shrink)

BackgroundFor a long time, in sports, researchers have tried to understand an expert by comparing them with novices, raising the doubts if the visual search characteristics distinguish experts from novices. Therefore, the aim of the present study was to review and conduct a meta-analysis to evaluate the differences in visual search behavior between experts and novices in team sports athletes.MethodsThis systematic review with meta-analysis followed the PRISMA 2020 and Cochrane's guidelines. Healthy team athletes were included, which engaged in regular practice, (...) from any sex or competitive level, specifically classified a priori as expert or novice in the original research. We considered only research published in peer-reviewed journals, with no limitations regarding date or language. It was considered healthy team sport athletes engaged in regular practice. The scenarios could be in situ or film-based. The databases of EBSCO, PubMed, Scopus, SPORTDiscus, and Web of Science were used to perform the searches. The risk of bias was calculated through the RoBANS tool.ResultsFrom a total of 6,257 records, of which 985 were duplicates, titles and abstracts of 5,272 were screened, and 45 required full-text analysis. Of those, 23 were excluded due to not fulfilling the eligibility criteria regarding participants. In the end, 22 studies were selected, however, as two studies were part of the same trial and were analyzed conjointly.DiscussionExperts showed to be older and with more years of practice. The ability to distinguish experts from novices was not so clear regarding the variables analyzed. This could be due to the strategies chosen in each study, which were specific to each scenario, and when grouping all together, it was lost information within non-representative averages. The distinction between experts and novices was not clear, showing a lot of heterogeneity in the included studies. The expert classification itself may have been the conditioning aspect for these results, retaining the doubt and the need for more studies in the field.Systematic review registrationThe protocol was pre-registered in OSF.

Psychological flexibility is a key concept of acceptation and commitment therapy. This factor has been linked with psychological wellbeing and associated factors, such as quality of life, in cancer patients. These and other positive results of acceptation and commitment therapy in cancer patients found in previous research could be enhanced by using mhealth tools. A three-arm randomized superiority clinical trial, with a pre-post-follow-up repeated measures intergroup design with a 1:1:1 allocation ratio is proposed. A hundred and twenty cancer patients will (...) be randomly assigned to one of the following interventions: face-to-face ACT + mobile application, face-to-face ACT, and Waitlist control group. The primary expected outcome is to observe significant improvements in psychological flexibility acceptance and action questionnaire- II in the face-to-face ACT + app group, after comparing baseline and post-treatment scores, and the scores will remain stable in the two assessment points, 3 and 6 months after the intervention. Secondary expected outcomes are significant increasing scores in quality of life and post-traumatic-growth, and significant decreasing scores in anxiety and depression, insomnia and fatigue at the same assessment points. Also, it is expected that the scores of this group will be higher than the scores of the face-to-face ACT group and the waitlist control group. This study aims to assess the efficacy of a combined intervention for psychological flexibility and associated symptoms in cancer patients. The results of this protocol may help to consider the use of acceptation and commitment therapy and mhealth applications in cancer settings as a valid therapeutic choice.Clinical Trial Registration[www.ClinicalTrials.gov], identifier [NCT05126823].

El Festival Flores de la Diáspora Africana surge en 1999 en Costa Rica, organizado por la Fundación Arte y Cultura para el Desarrollo, con el propósito de promover las manifestaciones artísticas y culturales de la población afrocostarricense en particular, y de los pueblos afrodescendientes y africanos, de manera general. A lo largo de diecinueve ediciones, se ha colocado la cultura de matriz africana en el más alto nivel, con la presencia de grupos de ballet folclórico como el Kilandukilu de Angola, (...) el Ballet Garífuna de Honduras, la bailarina Bethania Nascimento, perteneciente al Alvin Hailey Ballet, y el Opus Dance Theater de New York. En el bel canto, la soprano Sarah Carrere, dio fe de su gran talento franco-senegalés, así como en gospel el coro de la iglesia St. Agustine de Washington, y grupos como Master Key, Charleene Stuart y Sasha Campbell, de Costa Rica, conquistaron la audiencia con ritmos como gospel, spiritual, R&B y Soul, sin olvidar las agrupaciones nacionales de Calipso, que han dejado su huella en el Festival.En esa pasión por mostrar los mejores representantes de las diferentes manifestaciones del arte y la cultura de la Diáspora Africana, en 2012 la Fundación invitó a Costa Rica al Premio Nobel de Literatura de 1984, Derek Walcott. Para dar continuidad a este trabajo con los artífices de la palabra, también en 2013 se realizó el 1er Encuentro de Escritores y Poetas Afrodescendientes, Indígenas y Sinodescendientes, cuyo resultado fue la antología: Tenemos la Palabra, en la cual se muestra el trabajo de casi cincuenta creadores. Las escritoras Eintou Pearl Springer (Trinidad y Tobago), Melanie Taylor (Panamá), Myrna Manzanares (Belice) y Nancy Morejón (Cuba), fueron publicadas en dicha antología. Hoy nos llena de satisfacción publicar en la Revista Ístmica una parte de su obra poética1, así como su respectiva traducción al español, buscando exaltar su trabajo artístico y visibilizar la literatura escrita por mujeres afrodescendientes en el Caribe.

Este artículo plantea un diálogo sobre la ficción y su relevancia narrativa dentro del relato histórico contemporáneo colombiano, a la luz de sus relaciones transversales. Tras el Acuerdo de Contribución a la Verdad Histórica y la Reparación y de la consolidación del trabajo llevado a cabo por el Centro Nacional de Memoria Histórica iniciado hace casi una década con su primer informe, es pertinente volver sobre algunas ideas relacionadas con la manera en la que se narra la historia en Colombia. (...) En este sentido, se constata el valor histórico de la ficción, así como la vitalidad de sus diversos actores sociales y culturales, en sus intersecciones y recorridos por la memoria colectiva, en su materialidad y en su reinvención histórica. Los textos de ficción, por tanto, ofrecen caminos de reinvención de los relatos históricos, que no los sustituyen, pero sí empoderan a sus participantes/enunciantes, sus lectores/receptores y sus versiones/ relatos dentro de los procesos de memorias nacionales y humanas de la Colombia de hoy. Lo significativo de esta propuesta radica en que estos relatos son inclusivos, plurales y carecen del juicio moral hecho por una voz narradora autoritaria y única. (shrink)

This paper deals with Veronica Rodriguez-Blanco’s answer to the paradox of the normativity of law: How can autonomous self-legislating persons act, without compromising their autonomy and their will, following legal rules? Regarding Rodriguez-Blanco’s answer, I offer two main critiques. The first one is based on Rodriguez-Blanco’s comments to David Enoch’s paper in which I argue against the idea that a descriptive theoretical account of law can, and should, give an answer to general problems of normativity due to the fact that (...) a theoretical approach that engages in questions about the normativity of law cannot be purely descriptive, therefore against Rodriguez-Blanco I conclude that Enoch’s answer is the only response a descriptive account is able to offer. The second criticism focuses on Rodriguez-Blanco’s response to the paradox and argues that her solution is not, in fact, a descriptive one, but one that relies on strong normative premises, which as it turns out defend a perfectionist perspective towards the law.Resumen:Este trabajo analiza la respuesta que Veronica Rodriguez-Blanco propone para resolver la paradoja de la normatividad del derecho: ¿Cómo es posible que una persona autónoma actúe siguiendo los mandatos de normas jurídicas sin comprometer su autonomía ni su voluntad? El autor ofrece dos críticas a la respuesta de Rodriguez-Blanco. La primera de ellas está basada en los comentarios que Rodriguez-Blanco ha hecho sobre la propuesta de David Enoch. En este punto, el autor argumenta en contra de la idea según la cual una perspectiva descriptiva del derecho puede, y debe, tratar de responder a los problemas generales de la normatividad del derecho. De acuerdo con el autor, una perspectiva que pretenda dar respuesta a los problemas de la normatividad del derecho no puede ser una perspectiva puramente descriptiva. En este sentido, el autor sostiene que la respuesta que ofrece Enoch es la única respuesta que una perspectiva descriptiva del derecho puede dar. La segunda crítica está dirigida a la respuesta que Rodriguez-Blanco da sobre la paradoja de la normatividad. En este segundo punto el autor argumenta que la perspectiva de Rodriguez-Blanco no es una perspectiva descriptiva como ella presume, sino que adopta una perspectiva normativa la cual, además, está comprometida con una idea perfeccionista del derecho.

Oralità e scrittura in Platone. Milano: Università Degli Studi di Milano, 1999. Pp. 125. Paper, 16000 Lire.Trabattoni's masterful 1994 book, which the shorter 1999 book supplements in important ways, offers (...) nothing less than a refreshingly new and provocative interpretation of Plato's philosophy as a whole that makes it neither "conclusive-dogmatic" nor "problematic-sceptical" (7, 41-47, 161, 361-3). For Plato, on Trabattoni's account, while objective truth exists, any logos is incapable of fully expressing it and therefore refutable (158). On the other hand, dialectic can arrive at a logos sufficient (hikanos) for persuading a particular interlocutor in the context of a particular discussion (119-120), and thus for ethical and political action (330). Truth is therefore to be found onlyin dialogue (75-6, 338): that is, only where one person persuades another (249, 252, 328-9; 1999, 75). Persuasion and homologia are thus a necessary, though not sufficient condition of truth: only when capable of responding repeatedly to a wide variety of questions and objections does a persuasion deserve to be called "true" (158-9, 252, 329). This view rejects both the sophistical identification of truth with persuasion as such and the dogmatic identification of truth with universal doctrines.Because persuasion and homologia are thus essential to it, philosophy cannot be an objective science but must always be at its core a form of rhetoric (239, and thus protreptic and ad hominem, 165-6, 355, 359), which is what Trabattoni takes the Phaedrus to show (48-99). In 1999 Trabattoni brilliantly demonstrated the unity of the Phaedrus by showing how both the discussion of eros and the critique of writing are closely linked to this conception of philosophy as rhetoric (54-93). Philosophy is not, however, the kind of rhetoric that, focused on words rather than truth, fails to persuade in a way that is stable and enduring (87; 1999, 75-6).In the course of defending his "dialectical-dialogical" interpretation, Trabattoni provides an extraordinarily thorough and insightful critique of another interpretation that claims to offer a new Plato and that has become very influential in Trabattoni's native Italy: the "esotericist" interpretation, according to which fundamental questions left open by the dialogues are answered by a doctrine of principles which Plato communicated only orally. Trabattoni's 1999 book provides a very helpful account of the history and motives of the debate surrounding Plato's unwritten teachings, with regard to both their content and their significance (1-42). I see the following points of Trabattoni's critique as seriously challenging and, if unanswered, even discrediting the esotericist position: [End Page 269]1) While the esotericists interpret the critique of writing in the Phaedrus as arguing for the superiority of oral discourse as such, Trabattoni interprets it as arguing instead for the superiority of the dialogical situation in which interlocutors can be chosen and their questions and objections addressed (19-26; 1999, 83). Fixed oral doctrines would be no more dialogical than written doctrines and thus no more capable of engendering knowledge "in the soul" (63), much less of constituting this knowledge (25). What would be superior to Plato's writings, according to the Phaedrus, is a dialogue with Plato, not what Plato said orally, lifted out of its dialogical context and reported in writing by Aristotle (115; 1999, 84-5, 124). Trabattoni interprets the Seventh Letter, in his complementary accounts of 1994 and 1999, as similarly contradicting, rather than confirming, the esotericist interpretation (210-11; 1999, 116-9).2) Thomas Szlezàk has interpreted those passages where the main interlocutor deliberately leaves something out of the discussion ("Aussparungstellen") as referring to unwritten doctrines. Trabattoni argues that they are instead meant to indicate to the unknown reader, whose possible objections and questions cannot be anticipated, the possibility of proceeding further in the discussion (112-3, 182; 1999, 124).

The amount of information that is produced on a daily basis in the financial markets is vast and complex; consequently, the development of systems that simplify decision-making is an essential endeavor. In this article, several intelligent systems are proposed and tested to predict the closing price of the IBEX 35 index using more than ten years of historical data and five distinct architectures for neural networks. A multi-layer perceptron was the first step, followed by a simple recurrent neural network, a (...) gated recurrent unit network and two long-short-term memory (LSTM) networks. The results of the analyses performed on these models have demonstrated a powerful capacity for prediction. Additionally, the findings of this research point to the fact that the application of intelligent systems can simplify the decision-making process in financial markets, which is a substantial advantage. Furthermore, by comparing the predicted outcome errors between the models, the LSTM presents the lowest error with a higher computational time in the training phase. The LSTM was able to accurately forecast the closing price of the day as well as the price for the following one and two days in advance. In conclusion, the empirical results demonstrated that these models could accurately predict financial data for trading purposes and that the application of intelligent systems, such as the LSTM network, represents a promising advancement in financial technology.

The search for mechanisms has been a common practice in scientific research. However, since the empiricist critique of causality, and especially during the second third of the twentieth century, other non-mechanistic perspectives—especially deductivism—gained predominance. But the sustained effort of authors such as Michael Scriven, Mario Bunge and especially Wesley Salmon contributed to restoring the respectability of causality and mechanisms in philosophy of science. Some members of the causal family, usually lumped under the name of “new mechanistic philosophy”, emphasize the description (...) of mechanisms, especially causal ones, as a central aspect of explanation and other research practices in several areas of science. This approach offers viable solutions to the various ontological and methodological objections that are opposed to the two traditional approaches. In this work the basic characteristics of three philosophies that highlight the description of mechanisms as a central element to explanation and their suitability for the science of ecology are discussed.

Critical studies in higher education often embrace the ideas of the slowness movement to address time pressure. However, this desirable horizon presents some limitations. On the one hand, by emphasizing solutions at the individual level, boosting slowness may promote tactics incapable of producing changes to the underlying structural dynamics of time pressure. On the other hand, approaches based on slowness may also inadvertently foster a form of ethical paternalism within the context of ethical pluralism by prescribing substantive models of practice (...) ultimately based on ‘do this quickly or do it slowly.’ This theoretical research moves away from the temporal paradigm to that of the way of relating. Building upon the ethical concept of resonance, the approach focuses on a formal critique of the current socioeconomic and ethical dynamics of social acceleration, growth, and innovation that can contribute to projecting non-alienated relationships in higher education.

El presente artículo estudia las representaciones de mujeres con VIH/sida, en el libro Tiempos del SIDA. Relatos de la vida real, de Myriam Francis. El trabajo inicia con un análisis sobre la exclusión de los sujetos femeninos de la literatura “seropositiva” latinoamericana. Se plantea que las pocas representaciones que existen se enfocan en “mujeres sospechosas”, lo cual se repite, hasta cierto punto, en los textos de Francis seleccionados: “La última puerta”, “La viuda alegre” y “La chica alegre”. Luego, se ofrece (...) una explicación sobre el contexto en el que surgen las historias, un “pabellón-moridero” que se describe más bien como un espacio ameno, el cual, sin embargo, enfatiza la tragicidad que rodea a cada “caso”. Después, se estudian los tres relatos mencionados, en los que se mueven los símbolos primarios del mal (la mancilla, el pecado y la culpabilidad), de manera que una mujer es representada como una “víctima inocente” y otras, como “víctimas culpables” (fundamentalmente por sus “estilos de vida nocivos”). Finalmente, el trabajo concluye que la narrativa de Francis moviliza algunos principios de la “teoría de la degeneración”, para explicar las situaciones experimentadas por los personajes femeninos y ofrecer un mensaje didáctico-moralizante.
