8 March, now known as International Women’s Day, is a day for feminist claims where demonstrations are organized in over 150 countries, with the participation of millions of women all around the world. These demonstrations can be viewed as collective rituals and thus focus attention on the processes that facilitate different psychosocial effects. This work aims to explore the mechanisms involved in participation in the demonstrations of 8 March 2020, collective and ritualized feminist actions, and their correlates associated with personal (...) well-being and collective well-being, collective efficacy and collective growth, and behavioral intention to support the fight for women’s rights. To this end, a cross-cultural study was conducted with the participation of 2,854 people from countries in Latin America and Europe, with a retrospective correlational cross-sectional design and a convenience sample. Participants were divided between demonstration participants and non-demonstrators or followers who monitored participants through the media and social networks. Compared with non-demonstrators and with males, female and non-binary gender respondents had greater scores in mechanisms and criterion variables. Further random-effects model meta-analyses revealed that the perceived emotional synchrony was consistently associated with more proximal mechanisms, as well as with criterion variables. Finally, sequential moderation analyses showed that proposed mechanisms successfully mediated the effects of participation on every criterion variable. These results indicate that participation in 8M marches and demonstrations can be analyzed through the literature on collective rituals. As such, collective participation implies positive outcomes both individually and collectively, which are further reinforced through key psychological mechanisms, in line with a Durkheimian approach to collective rituals.

According to kin selection theory, indirect reproductive advantages may induce individuals to care for others with whom they share genes by common descent, and the amount of care, including self-sacrifice, will increase with the proportion of genes shared. Twins represent a natural situation in which this hypothesis can be tested. Twin pairs experience the same early environment because they were born and raised at the same time and in the same family but their genetic relatedness differs depending on zygosity. We (...) compared the degree of willingness to fight and sacrifice for the co-twin among monozygotic and dizygotic pairs in a sample of 1443 same-sex and opposite-sex twins. We also analyzed the effect of the subject’s gender and that of the co-twin on those altruistic behaviors. Results partly supported the postulated explanation. MZ twins were significantly more likely than DZ twins to self-sacrifice for their co-twins, but zygosity did not affect willingness to fight for him/her. The genders of the subject and of the co-twin, not genetic relatedness, were the best predictors of aggressive altruistic intentions. (shrink)

Se analiza la presencia intelectual de Ricardo Eduardo Latcham, ingeniero inglés, que llegado a Chile dio un mayor impulso al estudio tanto de la prehistoria latinoamericana como de la arqueología chilena, en los ámbitos del hábitat araucano y de las culturas del norte, en especial la atacameña. En este sentido, sus investigaciones prosiguieron a las de Uhle y posibilitaron integrar a los pueblos originarios del norte chileno al panorama de la prehistoria nacional. Latcham se adentró en registrar las conductas de (...) la sociedad chilena, tanto culta como popular, de fines del siglo XIX, legando agudas anotaciones etnográficas juntamente con una labor de tenaz divulgador de los progresos de la antropología europea, convirtiéndose en un corresponsal de las revistas británicas de la disciplina. Sus obras mayores las pudo difundir en el marco de sus actividades en el Museo de Historia Natural y en la Universidad de Chile. The intellectual presence of Ricardo E. Latcham, an English engineer whose arrival in Chile gave greater impulse to the study of Latin American pre-history and Chilean archaeology regarding araucano habitat and northern cultures, particularly the atacameno culture, is analyzed. His studies continued those of Uhle’s and made it possible to integrate the originary peoples of northern Chile to the panorama of the national pre-history. Latcham recorded the behaviors of both educated and popular Chilean society at the end of the 19th century, producing deep ethnographic records. He also conducted an enthusiastic dissemination of the progress made by European anthropology, becoming a correspondent of the British journals of this discipline. He disseminated his major works while working for the Museum of Natural History and the University of Chile. (shrink)

El objetivo de este trabajo es dar una mirada a la manera en que Roig opera en los ámbitos categoriales. Nuestro propósito es observar cómo el autor critica, confecciona, articula, utiliza, crea y entrelaza categorías, es decir, hemos querido hacer un alto en los procedimientos estructurales de su filosofar, en sus operaciones. Sostenemos como hipótesis que el rearme categorial al que Roig apela en múltiples pasajes de su obra implica, como operación de base, un cambio en el reconocimiento del lugar (...) de enunciación, y que éste se juega en parte importante en el empadronamiento de las categorías. Distinguimos al menos cinco operaciones categoriales en su trabajo reflexivo, las cuales pueden rastrearse a lo largo de toda su obra: (1) rescate, (2) crítica (3) reemplazo, (4) reelaboración e (5) invención. The aim of this work is to give a glance to the way in which Roig operates at categorical levels. Our intention is to observe how the author criticizes, makes, articulates, uses, creates and interlaces categories, that is to say, we wanted to take a break in the structural procedures of his philosophising, in his processes. We support as hypothesis that the categorical rearmament to that Roig appeals in multiple passages of his work involves, as a base operation, a change in the recognition of the place of enunciation, and that it plays an important part in the registration of the categories. We distinguish at least five categorical operations in his reflective work, which can be traced back throughout all his work: (1) rescue, (2) critique, (3) replacement, (4) re-elaboration and (5) invention.

This text focuses on the grounding of the legal and political structure of the modern state and starts from the Hobbesian conception of power as absolute and unlimited power. For their part, Spinoza and Bentham argue, against Hobbes, for the need to set certain limits to power, although they each based it on radically different grounds. Spinoza's political ontology makes it easy to carry out to the end what was permitted by a factual conception of power, which opens up the (...) possibility of thinking about power in a different way, namely, normatively. The difference between the utilitarian approach and that of Spinoza is his special conception of natural law, which leads him to maintain that it can only be defended where men have rights in common, that is, where there is civil order, making the preservation of our being the justification and limit of the institutionalization of the civil order. Bentham, however, remains true to his empiricist conception and a prisoner of its shortcomings, so that he cannot conceive of the limit of power except as self-limitation. The reason is that he does not have a sufficiently consistent concept of natural rights. Bentham's conception of them as “nonsense upon stilts” makes it impossible. (shrink)

This paper describes a one-day workshop format for introducing ethics into the engineering curriculum prepared at the University of Puerto Rico at Mayagüez (UPRM). It responds to the ethics criteria newly integrated into the accreditation process by the Accreditation Board of Engineering and Technology (ABET). It also employs an ethics across the curriculum (EAC) approach; engineers identify the ethical issues, write cases that dramatize these issues, and then develop exercises making use of these cases that are specially tailored to mainstream (...) engineering classes. The different activities and strategies employed in this workshop are set forth. Specific references are made to the cases and exercises developed as a result of these workshops. The paper ends by summarizing the different assessments made of the workshop by addressing the following questions: how did it contribute to the overall ABET effort at UPRM; could other universities benefit from a similar activity; and how did the participants evaluate the workshop?

This paper purports to analyze the verificationist theory of meaning proposed by logical positivism. According to this theory, only sentences verifiably by means of empirical observation have meanings. Our purpose is to show the reasons why the verificationist theory collapses. In order to do so, we will examine both the internal and external critiques to it. Among the internal critiques, we will show the logical positivists’ failed attempts to formulate an adequate weak verification criterion. Among the external critiques, we will (...) focus on the ones formulated by J.L. Austin on the basis of his theory of performative utterances. (shrink)

After having presented briefly the life and work of José Ortega y Gasset, it is shown that it is human life as ultimate reality and meaning that predominates in his thought, and the various treatment that Ortega y Gasset makes of this notion is explained. Résumé: Après avoir présenté rapidement la vie et l'oeuvre de José Ortega y Gasset, l'A. montre que c'est la vie humaine qui prédomine dans sa pensée comme réalité et signification ultimes, et explique le (...) traitement varié que fait Ortega y Gasset de cette notion.

Atrial fibrillation is the most common cardiac arrhythmia in clinical practice. It often starts with asymptomatic and short episodes, which are difficult to detect without the assistance of automatic monitoring tools. The vast majority of methods proposed for this purpose are based on quantifying the irregular ventricular response during the arrhythmia. However, although AF totally alters the atrial activity reflected on the electrocardiogram, replacing stable P-waves by chaotic and time-variant fibrillatory waves, this information has still not been explored for automated (...) screening of AF. Hence, a pioneering AF detector based on quantifying the variability over time of the AA morphological pattern is here proposed. Results from two public reference databases have proven that the proposed method outperforms current state-of-the-art algorithms, reporting accuracy higher than 90%. A less false positive rate in the presence of other arrhythmias different from AF was also noticed. Finally, the combination of this algorithm with the classical analysis of RR series variability also yielded a promising trade-off between AF accuracy and detection delay. Indeed, this combination provided similar accuracy than RR-based methods, but with a significantly shorter delay of 10 beats. (shrink)

Connectionist models provide a promising alternative to the traditional computational approach that has for several decades dominated cognitive science and artificial intelligence, although the nature of connectionist models and their relation to symbol processing remains controversial. Connectionist models can be characterized by three general computational features: distinct layers of interconnected units, recursive rules for updating the strengths of the connections during learning, and “simple” homogeneous computing elements. Using just these three features one can construct surprisingly elegant and powerful models of (...) memory, perception, motor control, categorization, and reasoning. What makes the connectionist approach unique is not its variety of representational possibilities or its departure from explicit rule-based models, or even its preoccupation with the brain metaphor. Rather, it is that connectionist models can be used to explore systematically the complex interaction between learning and representation, as we try to demonstrate through the analysis of several large networks.

The paper discusses the potential value of a deontic approach to database specification. More specifically, some different types of integrity constraints are considered and a distinction is drawn between necessary (hard) and deontic (soft) constraints.Databases are compared with other normative systems. A deontic logic for database specification is proposed and the problems of how to react to, and of how to correct, or repair, a situation which arises through norm violation are discussed in the context of this logic. The limitations (...) of the proposed logic and possible modifications and extensions of it are analysed. (shrink)
