Background: Current interventions to enhance patient self-efficacy, a key mediator of health behavior, have limited primary care application. Objective: To explore the effectiveness of an office-based intervention for training resident physicians to use self-efficacy-enhancing interviewing techniques. Design: Randomized controlled trial. Participants: Family medicine and internal medicine resident physicians at an academic medical center. Measurements: Resident use of SEE IT was coded from audio recordings of the physician-patient portion of two standardized patient instructor training visits and two unannounced post-training SP visits, all involving common physical and mental health conditions and behavior change issues. One post-training SP visit involved health conditions similar to those experienced in training, while the other involved new conditions. Results: Experimental group residents demonstrated significantly greater use of SEE IT than controls, starting after the first training visit and sustained through the final post-training visit. The mean effect of the intervention was significant [adjusted incidence rate ratio for increased use of SEE IT∈=∈1.94 ]. There were no significant effects of resident gender, race/ethnicity, specialty, training level, or SP health conditions. Conclusions: SP instructors can teach resident physicians to apply SEE IT during SP office visits, and the effects extend to health conditions beyond those used for training. Future studies should explore the effects of the intervention on practicing physicians, physician use of SEE IT during actual patient visits, and its influence on patient health behaviors and outcomes.

El artículo explora el concepto de Substitución, presente en la obra del Filósofo Emmanuel Levinas. El objetivo consiste en mostrar cómo a partir de tal concepto puede comprenderse la superación que el autor hace de la ontología a favor de la ética. Para lograr este objetivo se partirá, en primer lugar, de algunas precisiones previas al abordaje del problema. Posteriormente, se expondrá el concepto de substitución. Después, se discutirá en torno al lugar del sujeto en la relación para-otro. Finalmente, se harán unas consideraciones acerca de si, en efecto, se da una auténtica superación de la ontología a partir de la ética, en especial, a partir del concepto de Substitución.

Code-based cryptography is currently the second most promising post-quantum mathematical tool for quantum-resistant algorithms. Since in 2022 the first post-quantum standard Key Encapsulation Mechanism, Kyber (a latticed-based algorithm), was selected to be established as standard, and after that the National Institute of Standards and Technology post-quantum standardization call focused in code-based cryptosystems. Three of the four candidates that remain in the fourth round are code-based algorithms. In fact, the only non-code-based algorithm (SIKE) is now considered vulnerable. Due to this landscape, it is crucial to update previous results about these algorithms and their functioning. The Fujisaki-Okamoto transformation is a key part of the study of post-quantum algorithms and in this work we focus our analysis on Classic McEliece, BIKE and HQC proposals, and how they apply this transformation to obtain IND-CCA semantic security. Since after security the most important parameter in the evaluation of the algorithms is performance, we have compared the performance of the code-based algorithms of the NIST call considering the same architecture for all of them.

Este texto tiene como fin analizar el capítulo X de la Estructura de las revoluciones científicas (ERC) de Thomas Kuhn, especialmente su consideración de las Revoluciones como cambios de la visión del mundo (world view). Más que ahondar en cuestiones exegéticas, intentaré: a) explicitar las líneas generales del cambio de paradigma y del cambio de la visión del mundo; b) ubicar las reflexiones en el contexto de la tesis de la inconmensurabilidad; c) identificar las amenazas que podría comportar el planteamiento kuhniano para el Realismo científico; y d) esbozaré algunos modos para escapar de ellas.

Tomando como punto de partida hermenéutico lo que Martin Heidegger denominó como olvido del ser, en el contexto de su ambiciosa crítica a la metafísica occidental como ontoteología, se pone en ejercicio una hermenéutica analógico-icónica (deudora del modelo postulado por el filósofo mexicano Mauricio Beuchot) que permite recuperarlo en el ámbito jurídico, respetando la diferencia ontológica, mediante el recurso a la analogicidad y a la iconicidad como propiedades ontológicas del ser jurídico. Para ello se lleva a cabo una crítica de las principales ontologías jurídicas (iusnaturalismos, iuspositivismos y antiformalismos jurídicos), con el objetivo de articular ciertas bases que permitan desarrollar hoy una ontología analógico-icónica de lo jurídico.

Este trabajo tiene un doble propósito. Por un lado, pretende polemizar acerca de algunas cuestiones conceptuales del pensamiento suareciano, acaso no siempre comprendidas en todo su alcance; por otro, exponer la originalidad y la importancia de la contribución de este autor a la configuración de las principales vías que sigue la filosofía jurídica moderna y sus desarrollos posteriores. Y para ello, por razones de extensión y oportunidad, se centra en la cuestión de la validez normativa, cuyo fundamento y estructura permite tanto una crítica de las principales teorías contemporáneas, como dar cuenta de la vigencia esencial de la contribución de Suárez a la teoría jurídica y constitucional.

La Revolución Francesa (1789) ha despertado desde sus impresionantes acontecimientos, las más diversas reacciones y las más inimaginadas formas de interpretarlos. El "problema social" durante las primeras décadas del siglo XIX, que aflora en parte como consecuencia de esta "aurora del mundo" contemporáneo, determinó una nueva manera de contemplar este acontecimiento histórico universal. Tres personalidades intelectuales de primer rango. Lorenz von Stein, Karl Marx y Alexis de Tocqueville, procedentes de tres mundos político-sociales y académicos diversos, se enfrentan a evaluar el significado de la Revolución Francesa a la luz de los convulsos acontecimientos de su siglo. Sus penetrantes miradas no sólo enfatizan en la actualidad imborrable de los acontecimientos derivados del 89 hasta Napoleón, sino que descubren un horizonte social para la historia de cuño decisivo. La historia deja de ser una historia de acontecimientos, de datos o fechas, en el sentido tradicional de crónica, e incluso la historia deja de contemplarse como un asunto racional en la tradición ilustrada. La Revolución Francesa, gracias a estos tres autores, supera su circunstancialidad épocal y se eleva a una categoría de estructura de sentido inmanente. En otros términos, a diferencia de su contemporáneo Leopold von Ranke, von Stein, Marx y Tocqueville construyen un nuevo sentido de la historia, particularmente de las raíces incuestionables del mundo contemporáneo.

Background: Nurses who practice limitation of therapeutic effort become fully involved in emotionally charged situations, which can affect them significantly on an emotional and professional level. Objectives: To describe the experience of intensive care nurses practicing limitation of therapeutic effort. Method: A qualitative, phenomenological study was performed within the intensive care units of the Madrid Hospitals Health Service. Purposeful and snowball sampling methods were used, and data collection methods included semi-structured and unstructured interviews, researcher field notes, and participants’ personal letters. The Giorgi proposal for data analysis was used on the data. Ethical considerations: This study was approved by the Ethical Research Committee of the relevant hospital and by the Ethics Committee of the Rey Juan Carlos University and was guided by the ethical principles of voluntary enrollment, anonymity, privacy, and confidentiality. Results: In total, 22 nurses participated and 3 themes were identified regarding the nurses’ experiences when faced with limitation of therapeutic effort: (a) experiencing relief, (b) accepting the medical decision, and (c) implementing limitation of therapeutic effort. Conclusion: Nurses felt that, although they were burdened with the responsibility of implementing limitation of therapeutic effort, they were being left out of the final decision-making process regarding the same.

We investigate whether age profiles of ethnobiological knowledge development are consistent with predictions derived from life history theory about the timing of productivity and reproduction. Life history models predict complementary knowledge profiles developing across the lifespan for women and men as they experience changes in embodied capital and the needs of dependent offspring. We evaluate these predictions using an ethnobiological knowledge assessment tool developed for an off-grid pastoralist population known as Choyeros, from Baja California Sur, Mexico. Our results indicate that while individuals acquire knowledge of most dangerous items and edible resources by early adulthood, knowledge of plants and animals relevant to the age and sex divided labor domains and ecologies (e.g., women’s house gardens, men’s herding activities in the wilderness) continues to develop into middle adulthood but to different degrees and at different rates for men and women. As the demands of offspring on parents accumulate with age, reproductive-aged adults continue to develop their knowledge to meet their children’s needs. After controlling for vision, our analysis indicates that many post-reproductive adults show the greatest ethnobiological knowledge. These findings extend our understanding of the evolved human life history by illustrating how changes in embodied capital and the needs of dependent offspring predict the development of men’s and women’s ethnobiological knowledge across the lifespan.

Although entrepreneurial intention has been widely studied using cognitive models, we still lack entrepreneurial vocation and, therefore, lack disruptive innovations. Entrepreneurship scholars have some understanding of the reasons underlying this weakness, although there is much room for improvement in our learning concerning how to promote entrepreneurship among university students, especially in the transformed context of digital technologies. This paper focuses on the early stages of start-up, and in particular seeks to evaluate what role social and psychological factors play in the development of entrepreneurial intentions. Drawing on network theory, we consider the impact of social networks on entrepreneurial intention. Specifically, we analyze the influence of two types of social networks: face-to-face and online social networks, with the latter proving especially important in digital transformations. In addition, based on affective congruency theory, we relate affect with entrepreneurial intention. Particularly, we evaluate the influence of positive and negative dispositional affectivity on the formation of entrepreneurial intentions. Finally, since affect and emotions can also be related with social relationships, we analyze whether dispositional affectivities influence entrepreneurial intention through the mediation effect of social networks. Using structural equation modeling, we confirm the impact of both online and face-to-face social networks, as well as positive dispositional affectivity on entrepreneurial intention for 589 higher education students in Spain. However, negative dispositional affectivity is not seen to influence entrepreneurial intention. Furthermore, both face-to-face and online social networks are influenced by positive dispositional affectivity. Moreover, these two types of networks can even partially mediate the relationship between positive dispositional affectivity and entrepreneurial intention. Positive dispositional affectivity can thus influence entrepreneurial intention in two different ways: directly and indirectly through both face-to-face and online social networks. This study provides further insights and adds to the literature on affect, social networks, and entrepreneurial intention. From a broader perspective, we also contribute to the literature on disruptive innovations by explaining how the development of entrepreneurial intentions would have positive consequences for university students vis-à-vis achieving these disruptive innovations.
