The present work attempts to evaluate in what manner the Marian virtues marked out throughout the Middle Ages with respect to women, contribute powerfully to the dignification of women and their redemption from the traditional accusations that they are a perverting influence on humanity.

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.

A common approach for measuring the effectiveness of an education system or a school is the estimation of the impact that school interventions have on students’ academic performance. However, the latest trends aim to extend the focus beyond students’ acquisition of knowledge and skills, and to consider aspects such as well-being in the academic context. For this reason, the 2015 edition of the international assessment system PISA incorporated a new tool aimed at evaluating the socio-affective variables related to the well-being (...) of students. It is based on a definition focused on the five dimensions proposed in PISA theoretical framework: cognitive, psychological, social, physical and material. The main purpose of this study is to identify the well-being components that significantly affect student academic performance and to estimate the magnitude of school effects on the well-being of students in OECD countries, the school effect being understood as the ability of schools to increase subjective student well-being. To achieve this goal, we analyzed the responses of 234,000 students from thirty-five OECD countries to PISA 2015 questionnaires. Specifically, we considered non-cognitive variables in the questionnaires and student performance in science. The results indicated that the cognitive well-being dimension, composed of enjoyment of science, self-efficacy and instrumental motivation, as well as the test anxiety all had a consistent relationship with student performance across countries. In addition, the school effect, estimated through a two-level hierarchical linear model, in terms of student well-being was systematically low. While the school effect accounted for approximately 25% of the variance in the results for the cognitive dimension, only 5-9% of variance in well-being indicators was attributable to it. This suggests that the influence of school on student welfare is weak, and the effect is similar across countries. The present study contributes to the general discussion currently underway about the definition of well-being and the connection between well-being and achievement. The results highlighted two complementary concerns: there is a clear need to promote socio-emotional education in schools, and it is important to develop a rigorous framework for well-being assessment. The implications of the results and proposals for future studies are discussed. (shrink)

El texto presenta un adelanto de un profundo “trayecto” de trabajo colectivo en curso impulsado por un grupo de jóvenes investigadores y docentes que integran el Programa “Problemáticas comunicacionales barriales, organizacionales y políticas. Experiencias de lucha y resistencia a comienzos de siglo XXI en la provincia de Córdoba” (Argentina), desde el año 2011. La sistematización de las distintas experiencias, que presenta el libro, permite poner en común las peculiaridades de los contradictorios escenarios de conflicto y resistencia analizados, organizada en tres (...) capítulos que repasan con cuidadosa “vigilancia epistemológica” los procesos realizados con los actores sociales que integran los proyectos a saber: habitantes de las ciudades-barrio, trabajadores de la economía solidaria y vecinos e instituciones que forman parte de instancias participativas en los gobiernos locales.

En el presente artículo analizamos la Internet desde su origen hasta la actualidad considerándola como una unidad integrada por otras tecnologías de comunicación e información, donde todos tienen la posibilidad de hablar. A partir de esta condición inicial dividimos el análisis en dos direcciones: la red como tecno-capitalismo, y la red como «comunista», «comunitaria», «solidaria», «socialista», «democrática».

El estudio comparativo de la Ley de Prensa de Brasil y la ley de Servicios de Comunicación Audiovisual de Argentina es el análisis empírico de la construcción de un paradigma en la teoría de la comunicación basado en el estudio de la filosofía de G. W. Leibniz, tomando como pilares la filosofía y teoría de la comunicación de Jürgen Habermas y las ideas de complejidad y paradigma de Edgar Morin.

Critical aspects in the field of education are currently related to low levels of socioemotional competences and high rates of school dropouts. However, there are no standard practices or guidelines for helping countries to assess and train social and emotional competences. To overcome this limitation, the project Learning to be (L2B) aims to propose a comprehensive model of the assessment and development of social and emotional competences that bring together policymakers, researchers, teachers, school authorities and learners from different participating countries: (...) Finland, Italy, Latvia, Lithuania, Portugal, Slovenia, and Spain. The project attempts to create an international framework for regulating activities and supporting teachers working on the social and emotional competences of the students and to provide tools which can be used across countries. The aim of the paper is to describe how L2B has been developed in Spain by analyzing the contributions of the international framework and extracting the specific needs in the Spanish context. Specifically, we describe two products of the project: a) the process for creating a toolkit, a tool focused on creating activities and materials for helping teachers develop social and emotional competences of students and b) the results of an exploratory study in Spain in which social and emotional competences are assessed and compared to the international framework. First, we explain the definition of social and emotional competences used for creating the toolkit. Second, we analyze responses of Spanish students to questionnaires administered before applying the toolkit in the schools. The paper describes social and emotional competences in Spain and evaluates the overlap between relevant variables in Spain and those used for developing the toolkit, the international tool. Specific needs in Spain are discussed, as well as the contribution of the project for promoting the improved development of students’ social and emotional competences, improving learning outcomes and stronger social cohesion in schools and local communities, as well as the utility of the results for creating new educational policies.

Due to the COVID-19 Pandemic, several changes have been forcibly made and observed in various fields and areas of society, one of which include the field of education; the foundation of the formation of intellect and knowledge. After two years of studying indoors and private educational institutions holding virtual classes, the time has finally come for students to be re- adjusted once more to the blended mode of learning; a combination of virtual and in-person classes. Thus, this study aimed to (...) investigate the development of students’ study habits and how these habits could potentially affect the students’ academic achievement or performance. The study utilized a descriptivecorrelational design to examine the impact of study habits to the academic performance of 137 senior high school students. The study made use of the Palsane and Sharma’s Study Habits Inventory, or also known as PSSHI, and using this instrument, the study has been able to procure sufficient results that will answer the present study’s problems. Using linear regression analysis, the present study found that there was a significance between the study habits and academic performance of the senior high school students, thus the study’s null hypothesis was eventually rejected.

A growing number of consumer technology companies are aiming to convince older people that humanoid robots make helpful tools to support aging-in-place. As hybrid devices, socially assistive robots (SARs) are situated between health monitoring tools, familiar digital assistants, security aids, and more advanced AI-powered devices. Consequently, they implicate older people’s privacy in complex ways. Such devices are marketed to perform functions common to smart speakers (e.g., Amazon Echo) and smart home platforms (e.g., Google Home), while other functions are more specific (...) to older people, including health and safety monitoring and serving as companions to mitigate loneliness. Privacy is a key value central to debates about the ethics of using SARs in aged care, yet there has been very little interchange between these debates and the robust theoretical discussion in the legal literature about the future of privacy and AI governance. Drawing on two qualitative studies of older people’s views on consumer SARs, the paper contributes novel findings about older people’s thinking on privacy and data governance at the intersection of their experiences with present day digital technologies and projections for future AI systems, and places their views in dialogue with debates about the future of privacy protection and AI governance.

What is it for history to matter? Stephen Gould argued that unpredictability is part of the answer. For example, the “fact“ that repeated replays of the history of life would end differently every time is a sign that history matters to the course of evolution. But there is a problem here: if a particular point in the past leaves open alternative possible futures, then in what sense does that point in the past matter with regard to which of the outcomes (...) occurs? We argue that unpredictability is central to the importance of history. However, it is not the unpredictability of the future, but rather the unpredictability of the past itself that is the key. History matters when a particular future depends on a particular past that was not bound to happen, but did. (shrink)

Stemming from Uexkull’s fundamental concepts of Umwelt and Innenwelt as developed in the biosemiotic approach of Ferreira 2010, 2011, the present work models mathematically the semiosis of cognition and proposes an artificial cognitive architecture to be deployed in a robotic structure.

Mentioning products or brands on Facebook enables individuals to display an ideal self to others through a form of virtual conspicuous consumption. Drawing on conspicuous donation behaviour literature, we investigate ‘conspicuous virtue signalling’, as conspicuous consumption on Facebook. CVS occurs when an individual mentions a charity on their Facebook profile. We investigate need for uniqueness and attention to social comparison information as antecedents of two types of CVS–self-oriented and other-oriented. We also explore the relationship between CVS and self-esteem, and offline (...) prosocial and unethical behaviour intentions. Data from two studies, a college survey and an adult survey via MTurk, were analysed using structural equation modelling. Results indicate that NFU predicts both forms of CVS, while ATSCI influences both forms of CVS for adults and other-oriented CVS for students. Self-esteem is enhanced by self-oriented CVS. Self-oriented CVS predicts donation intention whereas other-oriented CVS significantly reduces donation intention for both samples. Furthermore, a significant relationship between CVS and purchase intention of counterfeit luxury goods is revealed. Findings provide insights into conspicuous virtue signalling and the relationship between CVS on Facebook and offline behavioural intentions. (shrink)

La industria de alimentos vegetales consume grandes volúmenes de agua de buena calidad y genera grandes cantida­des de agua residual. Uno de los sistemas que se pueden aplicar para reducir el consumo y el vertido de agua es la reutilización del agua de lavado. Para llevar a cabo la reutilización del agua sin comprometer la seguridad microbiológica y química de los alimentos es necesario optimizar el uso de agentes antimicrobia­nos. El cloro ha sido tradicionalmente el tratamiento de desinfec­ción usado por (...) la industria hortofrutícola para el agua de lavado. Sin embargo, su uso tiene la desventaja de la acumulación de subproductos de desinfección, lo que ha impulsado el estudio y el uso de desinfectantes alternativos como el ácido peroxiacéti­co. En cualquier caso, el mantenimiento de la seguridad micro­biológica y química de los alimentos vegetales frescos, en lo que respecta a la etapa de lavado, pasa por la selección de los límites operacionales que deben mantenerse en cuanto a la concentra­ción de desinfectante, así como la monitorización y control de los parámetros críticos relacionados con la desinfección, como es el contenido en materia orgánica. La optimización de la desinfec­ción tiene que tener en cuenta las peculiaridades de cada caso, incluyendo el tipo de producto lavado, el desinfectante usado, y el diseño y manejo de la línea de lavado.

Resource rationality may explain suboptimal patterns of reasoning; but what of “anti-Bayesian” effects where the mind updates in a direction opposite the one it should? We present two phenomena — belief polarization and the size-weight illusion — that are not obviously explained by performance- or resource-based constraints, nor by the authors’ brief discussion of reference repulsion. Can resource rationality accommodate them?

How much bacterial evolution occurs in our intestines and which factors control it are currently burning questions. The formation of new ecotypes, some of which capable of coexisting for long periods of time, is highly likely in our guts. Horizontal gene transfer driven by temperate phages that can perform lysogeny is also widespread in mammalian intestines. Yet, the roles of mutation and especially lysogeny as key drivers of gut bacterial adaptation remain poorly understood. The mammalian gut contains hundreds of bacterial (...) species, each with many strains and ecotypes, whose abundance varies along the lifetime of a host. A continuous high input of mutations and horizontal gene transfer events mediated by temperate phages drives that diversity. Future experiments to study the interaction between mutations that cause adaptation in microbiomes and lysogenic events with different costs and benefits will be key to understand the dynamic microbiomes of mammals.

The present paper stems from the biosemiotic modelling of individual artificial cognition proposed by Ferreira and Caldas (2012) but goes further by introducing the concept of Umwelt Overlap. The introduction of this concept is of fundamental importance making the present model closer to natural cognition. In fact cognition can only be viewed as a purely individual phenomenon for analytical purposes. In nature it always involves the crisscrossing of the spheres of action of those sharing the same environmental bubble. Plus, the (...) incorporation of that concept is vital to understand the complex semiosis that sustains collective tissues, societies, regulating collective cognition and consequently cooperative action. The concept of Umwelt Overlap broadens the range of applicability of the previous model to several distinct domains allowing for example for its application to multi-agent cooperative autonomous systems. In this paper a Middle Size League RoboCup soccer team is used as an example of a possible application. (shrink)

In the Leviathan, power can be understood in two different senses, which are carefully discriminated in its Latin version by the use of the terms potentia and potestas to translate, depending on the context and the type of power concerned, the English power. Potentia and potestas, although types of power of a different nature – one, the physical power that bodies have to take effect on each other; the other, the juridical power, out of which legal effects as justice itself (...) come about –, are mutually implicated in the intertwining of juridical representations. This article aims to explore the consequences that follow from this ambivalent concept of power to think about justice and natural right. (shrink)

This chapter explores the relations of different kinds of power, philosophically understood – sovereign power, disciplinary power, and biopower – and argues that the politics of the Star Wars galaxy is animated by an ontology, or metaphysical picture, centered on power. It further argues that The Mandalorian criticizes this power ontology with the introduction of the Child, Grogu, who generates a different kind of Force: a relational ontology of love. Grogu and the love he generates point to a different way (...) of being in the world than power. Ultimately, The Mandalorian offers a different ontology of power – an ontology of love – as a radical alternative to the bindings of political power. Palpatine is correct that power dynamics shape the confrontational relationship between the Jedi and Sith, which is fed by the Jedi's disavowal of strong attachments. (shrink)

O presente artigo tem dois objectivos: por um lado, o de analisar os conceitos de percepçáo e memória no cinema segundo a fenomenologia de Maurice Merleau-Ponty em “Le Cinéma et la Nouvelle Psychologie” e, por outro lado, o de analisar estes mesmos conceitos no filme de Christopher Nolan, Memento . A nossa principal referência será a fenomenologia da percepçáo em Merleau-Ponty de modo a melhor compreendermos o interesse fenomenológico do cinema e deste filme em particular.

La Constitución de 1978 se ha convertido ya en el segundo texto de más larga duración en nuestra historia contemporánea, sólo superada por la Constitución de 1876, vigente durante cuarenta y siete años. Sin embargo, la situación real de una y otra no es comparable. Durante la vigencia del texto actual España ha sido modelo de significativos cambios, en la que se han dado muestras de prudencia y audacia, a la vez.

Does feature evolution stop once we have acquired sufficient features to perform a recognition task? With extended practice, novices may develop a more sophisticated feature space that allows them to perform more accurately or quickly. Our work on perceptual expertise indicates that feature learning and reorganization can continue even after an initial set of features is available to represent a novel class of objects.
