I show that the Lottery Paradox is just a version of the Sorites, and argue that this should modify our way of looking at the Paradox itself. In particular, I focus on what I call “the Cut-off Point Problem” and contend that this problem, well known by Sorites scholars, ought to play a key role in the debate on Kyburg’s puzzle. Very briefly, I show that, in the Lottery Paradox, the premises “ticket n°1 will lose”, “ticket n°2 will lose”… “ticket (...) n°1000 will lose” are equivalent to soritical premises of the form “~(the winning ticket is in {…, (tn)}) ⊃ ~(the winning ticket is in {…, tn, (tn + 1)})” (where “⊃” is the material conditional, “~” is the negation symbol, “tn” and “tn + 1” are “ticket n°n” and “ticket n°n + 1” respectively, and “{}” identify the elements of the lottery tickets’ set. The brackets in “(tn)” and “(tn + 1)” are meant to point out that in the antecedent of the conditional we do not always have a “tn” (and, as a result, a “tn + 1” in the consequent): consider the conditional “~(the winning ticket is in {}) ⊃ ~(the winning ticket is in {t1})”). As a result, failing to believe, for some ticket, that it will lose comes down to introducing a cut-off point in a chain of soritical premises. In this paper I explore the consequences of the different ways of blocking the Lottery Paradox with respect to the Cut-off Point Problem. A heap variant of the Lottery Paradox is especially relevant for evaluating the different solutions. One important result is that the most popular way out of the puzzle, i.e., denying the Lockean Thesis, becomes less attractive. Moreover, I show that, along with the debate on whether rational belief is closed under classical logic, the debate on the validity of modus ponens should play an important role in discussions on the Lottery Paradox. -/- .

Vann McGee has presented a putative counterexample to modus ponens. I show that (a slightly modified version of) McGee’s election scenario has the same structure as a famous lottery scenario by Kyburg. More specifically, McGee’s election story can be taken to show that, if the Lockean Thesis holds, rational belief is not closed under classical logic, including classical-logic modus ponens. This conclusion defies the existing accounts of McGee’s puzzle.

La intuición y su relación con la invención matemática es destacada por los autores franceses Henri Bergson y Henri Poincaré. Los dos asumen la intuición como un proceso intelectual, que requiere de la experiencia tanto física como matemática del individuo y cuyos resultados se observarán en la superficie de la conciencia, es decir, en el lenguaje matemático. Ambos asumen que la idea de intuición es necesaria para la invención matemática. En este artículo se muestran los puntos coincidentes entre Bergson y (...) Poincaré en torno a la relación intuición-invención, mostrando cómo su definición lleva a interpretar la intuición como un proceso y, finalmente, cómo la idea de esquema dinámico introducida por Bergson para explicar la invención está implícita en el pensamiento de Poincaré.

Uno de los temas de estudio de la filosofía de las matemáticas tiene que ver con cómo accedemos al conocimiento de los objetos de las matemáticas, al ser objetos abstractos. En este artículo mostraremos que esta forma de "acceso" es la intuición, entendida como un proceso dinámico que requiere de la experiencia de los matemáticos, cuyos efectos se verán en el mundo concreto. Partiendo del dilema expuesto por Benacerraf, revisaremos cómo la intuición es una posible solución y ha tenido un (...) papel protagónico en la epistemología de las matemáticas. Finalmente, revisaremos el papel de las ideas de Kitcher frente a la teoría del conocimiento matemático y el papel de la intuición. (shrink)

Se exponen las prácticas docentes de las educadoras de párvulos, que cumplen una función reproductora del nacionalismo que es internalizado en las niñas y niños como la ciudadanía chilena. Para ello, configuran un escenario lúdico que ritualiza la conducta cívica y patriótica, por medio de conmemoraciones cívicas fundadas en el belicismo de la guerra del Pacífico, sin considerar la realidad cosmopolita y de diversidad cultural presente en las aulas nortinas. A partir de esto, proponemos una nueva perspectiva respecto de la (...) realización de actos cívicos en la educación parvularia, para hacerlos más inclusivos y acordes a la realidad cultural de la región de Tarapacá, la más multicultural de Chile. This paper describes the teaching practices of pre-school teachers who play a reproductive role of nationalism internalized in children as Chilean citizenships. This happens as the result of a ludic scenario that ritualizes civic and patriotic conduct, through civic commemorations based on the Pacific war, regardless both the cosmopolitan reality and cultural diversity present in classrooms in the Northern part of Chile. Considering this, we propose a new perspective on conducting civic events in early childhood education, to make them more inclusive and consistent with the cultural reality of the region of Tarapacá, Chile's most multicultural region.

La historia de la matemática muestra como la intuición matemática ha estado presente en la invención y desarrollo de conceptos, teorías y procedimientos matemáticos. Así mismo, ha permeado el debate filosófico, los fundamentos de la matemática y los discursos educativos; otorgándole vigencia al estudio de este tema. En el presente artículo, se exponen los argumentos bajo los cuales es posible sustentar que la intuición es un proceso, que toma ideas que se presentan, inicialmente de manera “desordenada”, y que gracias al (...) contexto y los conocimientos previos del individuo las centran en una idea “fija” que será incorporada a la matemática por la lógica y la formalización.

El siguiente documento es el resultado de un seminario de investigación sobre novela policíaca latinoamericana reciente, desarrollado en el curso de Novela Latinoamericana, de la Facultad de Filosofía y Letras en la Universidad de La Salle. La fundamentación teórica del seminario tuvo como marco general la Estética de la Recepción fundada en la Escuela de Constanza, Alemania, por Hans Robert Jauss y Wolfgang Iser. Para el caso concreto de la teoría literaria sobre novela policíaca vista en perspectiva sociológica, preferimos apelar (...) a las reflexiones fundacionales de Roger Caillios (1942), las que tiene un sugestivo subtítulo, a saber, La novela policíaca. –De cómo la inteligencia se retira del mundo para consagrarse a sus juegos y de cómo la sociedad introduce sus problemas en éstos. Por otra parte, elegimos la novela corta de Roberto Bolaño, La pista de hielo; y sobre esta elaboramos distintas hipótesis de trabajo, hasta lograr, al juicio de nuestros lectores, una propuesta de teoría literaria, que dé cuenta de la nueva narrativa policíaca.

RESUMEN El artículo responde algunas críticas planteadas por Ignacio Ávila a mi interpretación de la epistemología davidsoniana. Presento argumentos en contra de: a) que sea necesario distinguir entre representaciones epistemológicamente “peligrosas”e “inofensivas”; b) que el empirismo mínimo sea un tipo de realismo directo; c) que mi uso de la expresión “evidencia distal” y el interés por la teoría de la correspondencia sean asuntos ajenos a Davidson. Finalmente, sostengo que la triangulación es un elemento fundamental de la epistemología davidsoniana, pues permite (...) sortear la ansiedad realista manteniéndose en una postura no representacionalista. ABSTRACT In this article, I respond to some of Ignacio Ávila's criticisms of my interpretation of Davidson’s epistemology. I argue against: a) the need to distinguish between epistemologically “dangerous” and “harmless” representations; b) the idea that minimal empiricism is a kind of direct realism; and c) the claim that my usage of the expression “distal evidence” and interest in the theory of correspondence are issues that do not pertain to Davidson. Finally, I claim that triangulation is a key element in Davidsonian epistemology since it allows us to deal with the realist anxiety while maintaining a non-representationalist viewpoint. (shrink)

Community leaders in Colombia have historically suffered processes of microaggressions and intimidation that threaten the free exercise of their voice in the processes of production of knowledge and in the participation of the planning of their territories. In this article, we explore the case study of the Network of Community Researchers (NCR), also known in Spanish as Red de Investigadores Comunitarios, promoted by the University of Antioquia, Colombia. The NCR is a commitment to the co-production of knowledge about human security (...) from below between community researchers and academics. This article analyses the contribution of the NCR to the human security of Medellin and a specific collection of capabilities for epistemic liberation of community researchers: the capability to be recognised as a producer of valid knowledge, to do through communicative openness, to learn from collective knowledge and to transform through collective action. The expansion of these four capabilities evidence processes of resistance and hermeneutic insurrection of some community leaders and activists who participate in the NCR. The analysis shows the contribution of the NCR to facilitate and generate a safe space in which community researchers communicate knowledge and practices and share experiences, risks, struggles, fears and collective dreams of transformation.

The participation of families in schools where their children study is a recurring research topic. This field tends to address the perception of parents or teaching staff. This work is novel in that it considers what teachers, and not families, do to facilitate this participation. The purpose of this work has been to contrast a theoretical model with a multidimensional questionnaire designed to obtain information on the assistance provided by teachers to improve parental involvement in schools. It will allow us (...) to lay the foundations for the content necessary for the initial and permanent training of teachers. Then, an initial questionnaire was created and, after being subjected to expert judgment, it was applied to 225 Spanish teachers, using a quantitative and a non-experimental methodology. After calculating the exploratory and confirmatory factor analysis and applying the structural equation model, a questionnaire was obtained that had satisfactory construct validity and reliability.

Job crafting has been established as a bottom-up work design instrument for promoting health and well-being in the workplace. In recent years, the concepts of job crafting have been applied to the university student context, proving to be positively related to student well-being. Building on person-centered analyses from the employment context, we assessed approach study crafting strategy combinations and the relationships to students’ exhaustion, study engagement, and general well-being. Data from 2,882 German university students were examined, collected online during the (...) summer term in 2020. Using latent profile analysis, we found five distinct crafting groups, which showed discriminate validity with regard to emotional exhaustion, engagement, and well-being. The results underscore the positive role of study crafting for students’ health and well-being. They further indicate a less important role of increasing social resources for emotional exhaustion when combined with a moderate increase in structural resources and a moderate increase in challenging demands. Our findings imply that interventions to promote study crafting should be considered to promote student health and well-being. (shrink)

Recently a role for the vagus nerve in conditioning food preferences was established in rodents. In a prospective controlled clinical trial in humans, invasive vagus nerve stimulation shifted food choice toward lower fat content. Here we explored whether hedonic aspects of an orally sampled food stimulus can be modulated by non-invasive transcutaneous vagus nerve stimulation (tVNS) in humans. In healthy participants (n= 10, five women, 20–32 years old, no obesity) we tested liking and wanting ratings of food samples with varying (...) fat or sugar content with or without tVNS in a sham-controlled within-participants design. To determine effects of tVNS on food intake, we also measured voluntary consumption of milkshake. Spontaneous eye blink rate was measured as a proxy for dopamine tone. Liking of low-fat, but not high-fat puddings, was higher for tVNS relative to sham stimulation. Other outcomes showed no differences. These findings support a role for the vagus nerve promoting post-ingestive reward signals. Our results suggest that tVNS may be used to increase liking of low-calorie foods, which may support healthier food choices. (shrink)

Prolonging working hours and presenteeism have been conceptualized as self-endangering coping behaviors in employees, which are related to health impairment. Drawing upon the self-regulation of behavior model, the goal achievement process, and Warr's vitamin model, we examined the antecedents and moderation effects regarding quantitative demands, autonomy, emotion regulation, and self-motivation competence of university students' self-endangering coping behaviors. Results from a cross-sectional survey of 3,546 German university students indicate that quantitative demands are positively related and autonomy has a u-shape connection with (...) self-endangering coping. Emotion regulation was shown to be a protective factor for prolonging working hours. Moreover, self-motivation moderated the relationship between quantitative demands and prolonging of working hours, but not in the assumed direction. Self-motivation showed a systematic positive relationship with prolonging of working hours, but no relationship with presenteeism. Autonomy moderated the relationship of quantitative demands with both self-endangering behaviors. We found no moderating effects for emotion regulation of quantitative demands or autonomy and self-endangering behaviors. Besides further practical implications, the results suggest that lecturers should design their courses accordingly with less time pressure and university students should be trained in the use of autonomy.

As evaluation of practitioners’ competence is largely based on self-report, accuracy in practitioners’ self-assessment is essential for ensuring high quality treatment-delivery. The aim of this study was to assess the relationship between independent observers’ ratings and practitioners’ self-reported treatment integrity ratings of Motivational interviewing. Practitioners were randomized to two types of supervision [i.e., regular institutional group supervision, or individual telephone supervision based on the MI Treatment Integrity code]. The mean age was 43.2 years, and 62.7 percent were females. All sessions (...) were recorded and evaluated with the MITI, and the MI skills were self-assessed with a questionnaire over a period of 12 months. The associations between self-reported and objectively assessed MI skills were overall weak, but increased slightly from baseline to the 12-months assessment. However, the self-ratings from the group that received monthly objective feedback were not more accurate than those participating in regular group supervision. These results expand findings from previous studies and have important implications for assessment of practitioners’ treatment fidelity: Practitioners may learn to improve the accuracy of self-assessment of competence, but to ensure that patients receive intended care, adherence and competence should be assessed objectively.

El artículo sostiene una relación fundacional entre la visión bioética potteriana con el cometido de la sostenibilidad. Teniendo en cuenta que V. R. Potter no desarrolló conceptualmente cómo y desde qué enfoque tendría que entenderse la sostenibilidad de la humanidad, se hace necesario mostrar tal desarrollo conceptual. Así, la visión bioética potteriana podría ser repensada y actualizada para enfrentar el desafío de la humanidad en la época actual. En este orden de ideas, se propone analizar descriptivamente los enfoques teóricos y (...) las ampliaciones conceptuales del concepto de sostenibilidad para reconocer en qué sentido contribuyen a la construcción de una supervivencia aceptable para la humanidad, en términos de la bioética global. Para esto, se presenta el eje teórico del desarrollo sostenible, del cual se resalta su componente sistémico e intergeneracional, sin dejar de exponer las críticas a su estructura de crecimiento económico y la incompatibilidad de esto con la visión bioética potteriana. Seguidamente, se expone la propuesta alternativa del ecodesarrollo y de la racionalidad ambiental, como elementos importantes para ampliar el paradigma de la sostenibilidad. Finalmente, se concluye con una integración de los elementos de ambos ejes teóricos como un punto de partida para pensar en la sostenibilidad de una visión bioética. (shrink)

In recent years it has been demonstrated that the use of the traditional property registry models involves the risk of corruption along with long waiting times. This paper points out the main problems associated with conventional models and makes a survey of the new ones that are based on blockchain technology. This type of model is already being developed as a proof of concept by different countries. With the use of this technology in land registry systems, it is possible to (...) improve the transparency of the processes as well as optimize costs and execution time. To show the theoretical results of this study, the Spanish land registry has been taken as an example of a use case scenario. (shrink)

IntroductionIncorporating technology in cognitive interventions represents an innovation, making them more accessible, flexible, and cost-effective. This will not be feasible without adequate user-technology fit. Bearing in mind the importance of developing cognitive interventions whose technology is appropriate for elderly people with cognitive impairment, the objective of this systematic review was to find evidence about usability and user experience measurements and features of stimulation, training, and cognitive rehabilitation technologies for older adults with mild cognitive impairment or dementia.MethodThe Medline, PubMed, Scopus, ScienceDirect, (...) and PsycINFO databases were searched for literature published in the last 10 years, and three researchers independently reviewed potentially eligible studies, following specific inclusion criteria. A systematic review of the studies was conducted, presenting a qualitative synthesis of usability and UX measures with their outcomes, study characteristics and features of the cognitive intervention technologies.ResultsTen studies were selected: five were cognitive stimulation and five were cognitive training. Most of them were computer-based programs with a serious game format. Efficiency and effectiveness were the most frequent measurements used for collecting objective usability data, showing that elderly people with cognitive impairment require more time and help but can complete tasks. Regarding UX or subjective usability data, questionnaires and scales were the most used methods, reporting positive experience despite certain difficulties with the interface in five studies.ConclusionMeasuring usability and UX in cognitive intervention technologies for older adults with MCI or dementia provides an integrated view that can contribute to their development according to the needs and characteristics of the target population. More research is required to include this population group in usability and UX studies, as well as standardized tools and consensus on the relationship of these terms to guarantee the future effectiveness of cognitive intervention technologies.Review registrationThis review was registered in the PROSPERO International Register of Systematic Review Protocols.

Uno de los problemas centrales que el filósofo francés Bernard Stiegler ha abordado para sostener una constitución tecno- lógica de la humanidad, es la cuestión del origen del hombre. El asunto recae en preguntarse si es posible pensar quién es el hombre desde esta tesis, sin volver a la metafísica o la filosofía trascendental. Esta posición ha de estar enraizada en una ontología que aprehenda el componente causal a nivel relacional, dejando de lado las explicaciones en las cuales la causa (...) es substancialista. Para dar desarrollo a esta propuesta, este artículo se compone de dos partes generales: la primera está destinada a presentar hasta dónde sigue y en dónde se separa Stiegler de la concepción zoo-antropológica de André Leroi-Gourhan sobre el origen del hombre; para luego explicar las bases epistemológicas y ontológicas sobre las que Stiegler erige sus tesis tecno-ontológica de la humanidad; a saber: los fundamentos de la transducción simondoniana y la diferancia derridiana.

La función de la educación es difundir las ventajas de vivir en sociedades democráticas, sin embargo, la diáspora de esas ventajas está articulada a intereses políticos y económicos globalizados; su misión: anestesiar a la sociedad para que observe en silencio el desmantelamiento de su proyecto de vida. La educación tradicional no fomenta la habilidad para leer la complejidad de esa realidad democrática. Se enfoca, principalmente, en aleccionar sobre las “ventajas” de la modernidad, donde la mayoría tiene como destino ser masas (...) de asalariados y una minoría, “heredar” la élite. Este documento, propone que para leer esta realidad, la ciudadanía debe ser alfabetizada más allá de la mera técnica que sólo sirva para leer, memorizar y escribir manuales; particularmente la alfabetización debe ser: reflexiva, crítica, basada en el diálogo de saberes y permanente; pero, éticamente coordinada por docentes intelectuales.

ObjectivesPrevious studies found a general increase in prejudice against Chinese people during the first months of the pandemic. The present study aims to consider inter-individual heterogeneity in stability and change regarding prejudice involving Chinese people during the pandemic. The first objective is to identify and describe different trajectories of prejudice over a seven-month period during the pandemic. The second and third objectives are to test the association between trajectory group membership and antecedent variables such as: socio-demographic factors and two psychological (...) mechanisms, namely economic threat and global citizenship identification.MethodsA representative Canadian sample according to age, gender and province of residence, was recruited for a 10-wave survey starting from April 2020 to December 2020. First, a group-based modeling approach was used to identify trajectories of prejudice. Second, a multinomial logistic regression model was used to test associations between membership in trajectories and antecedents.ResultsFour trajectories were identified. The first three trajectories have a low, high or very high level of prejudice against Chinese people which is relatively stable over time. The fourth trajectory reports low levels of prejudice in favor of Chinese people which become more positive throughout 2020. Regarding socio-demographic factors: gender is not associated with trajectory group membership, younger people are more likely to follow the trajectory in favor of Chinese people and conservatives are more likely to follow the highest trajectories against Chinese people. Regarding some psychological mechanisms: personal but not collective economic threat is associated with the trajectory in favor of Chinese people. Finally, the highest levels of prejudice are found when the strategy of identification is more local rather than global.ConclusionThe present study shows that Canadians differ in terms of both their level and change in prejudice against Chinese people throughout the pandemic with some socio-demographic groups being more likely than others to be associated with prejudice. The results also suggest that a promising way to tackle the major social issue of prejudice is to highlight a vision of the world where individuals are all “global citizens” facing the same challenge.

This article studies natural food packaging as enabling artifacts of the traditional material culture of Antioquia in Colombia. For this purpose, we consider artifacts as objective nodes that combine design and use intentions, functions, materials, histories, artifactual lineages, and cooperative relationships that stabilize ritualized practices of a human group. We take the example of natural packaging as artifacts that enablers and stabilizers of traditional cooking and food preparation practices. Natural packaging materials are here assumed to be leaves having some favorable (...) property to contain a food product. After providing a theoretical reflection, we analyze the data collected from fieldwork we conducted in two towns in Antioquia, Colombia (Santa Fe de Antioquia and Amagá), as well as from an interview with an expert in the field. Finally, we show that it is possible to postulate an analysis under a relational ontological description of a traditional practice with conceptual categories of the philosophy of technology. (shrink)
