En medio de una época donde la incertidumbre, la inseguridad y la desprotección crecen, la teoría de la hegemonía, elaborada por Gramsci y reformulada por E. Laclau y Ch. Mouffe, constituye un punto nodal para pensar la política. Esta categoría surge como respuesta a una crisis que pone en cuestión las concepciones tradicionales para explicar la contingencia de las formas históricas concretas. La sociedad no debe ser entendida como un espacio cerrado sino como una estructura, resultado de prácticas articulatorias que (...) organizan y constituyen las relaciones sociales. La hegemonía, entonces, entendida como articulación contingente de elementos en torno a las luchas de los agentes sociales concretos, configura una valiosa herramienta teórica para reflexionar acerca de nuestra compleja realidad.

La significación del espacio como construcción subjetiva y como subjetivadora y su aplicación al aula escolar y a la escuela.

Decisions in the environmental and in particular the climate domain are burdened with uncertainty. Here, we focus on uncertainties faced by individuals when making decisions about environmental behavior, and we use the statistical sampling framework to develop a classification of different sources of uncertainty they encounter. We then map these sources to different public policy strategies aiming to help individuals cope with uncertainty when making environmental decisions.

La “referencia al origen es un invariante cultural” . Sin embargo, cada país tiene modos particulares de procesar su propia historia. Este trabajo analiza una de las modalidades en que –en Argentina– se narra ese origen, en el contexto de los bicentenarios latinoamericanos. Ese momento originario –la Revolución de Mayo de 1810– aparece representado en producciones literarias que han sido best sellers de historia. Esos relatos de no-ficción junto a otros de ficción permiten problematizar la cuestión del género y su (...) relación con “la nación” como matriz cultural. Un modo de imaginar un “nosotros” y de permitir ciertas inclusiones y exclusiones identitarias en el momento del origen y en el presente del Bicentenario. (shrink)

This study presents a web-based sentence comprehension test aimed at identifying high school students who are at risk for a language delay. By assessing linguistic skills on a sample of high school students with Italian as an L2 and their monolingual peers, attending a vocational school, we were able to identify a subgroup of L2 students with consistent difficulties in sentence comprehension, though their reading skills were within the average range. The same subgroup revealed to experience a lack of support (...) within the school context, suggesting that poor L2 skills might be a critical variable to consider in order to identify students at risk for school exclusion. Regarding the test, accuracy to the on-line sentence comprehension task was significantly predicted by reading abilities and vocabulary skills, thus indicating that this test might represent a rapid but efficient way to assess linguistic abilities at school. We recommend that establishing a valid and practical procedure for the evaluation of linguistic skills in bilingual students who struggle with their L2 is the first step towards promoting social inclusion in the multilingual classroom, in order to increase their ability to actively participate in school and social activities.

À la fin du xixe siècle, la plupart des nations latino-américaines étaient intégrées au commerce international par l’exportation de produits agricoles, miniers ou d’élevage et l’importation de biens manufacturés. Le développement des moyens de transport, principalement le train, et le processus d’urbanisation s’étaient accélérés. De nombreuses villes surgirent, de grandes villes furent transformées et embellies par de nouveaux bâtiments, parcs et jardins. La demande de main d’œuvre impulsa un...

Doing phenomenological research entails a complex process that is only minimally published in scientific journals. What is often missing reflects how being in research calls into question the researchers themselves. Anyone who has conducted qualitative empirical research knows that personal engagement does not come at no cost; there are multiple pedagogical and professional practice gains. This article’s aim is to share the phenomenology behind phenomenology: the reflection and personal experience of doing/being in phenomenological research and the personal narrative of what (...) this experience has meant concerning the authors' own context: health care and nursing. Taking advantage of a conducted research exploring the lived experience of family caregivers of hematological patients assisted at home, we propose considerations about the perceived epistemic and cognitive gains, the formative and personal/professional sequels of having been reflective participants of phenomenologically oriented research.

Cognitive science has been traditionally organized around the individual as the basic unit of cognition. Despite developments in areas such as communication, human–machine interaction, group behavior, and community organization, the individual-centric approach heavily dominates both cognitive research and its application. A promising direction for cognitive science is the study of augmented intelligence, or the way social and technological systems interact with and extend individual cognition. The cognitive science of augmented intelligence holds promise in helping society tackle major real-world challenges that (...) can only be discovered and solved by teams made of individuals and machines with complementary skills who can productively collaborate with each other.

Individual differences in demographics, personality, and other related beliefs are associated with coronavirus disease 2019 threat beliefs. However, the relative contributions of these different types of individual differences to COVID-19 threat beliefs are not known. In this study, a total of 1,700 participants in Croatia completed a survey that included questions about COVID-19 risks, questions about related beliefs including vaccination beliefs, trust in the health system, trust in scientists, and trust in the political system, the HEXACO 60 personality inventory, as (...) well as demographic questions about gender, age, chronic diseases, and region. We used hierarchical regression analyses to examine the proportion of variance explained by demographics, personality, and other related beliefs. All three types of individual differences explained a part of the variance of COVID-19 threat beliefs, with related beliefs explaining the largest part. Personality facets explained a slightly larger amount of variance than personality factors. These results have implications for communication about COVID-19. (shrink)

Although the literature on probability has traditionally considered certain assumptions about what were the aims and scope of the "Grundbegriffe der Wahrscheinlichkeitsrechnung" in the development of probability theory, a detailed analysis of Kolmogorov's work in particular regarding its passage through the frequentist and propensionalist interpretations, leads to the conclusion that hypotheses usually raised in the literature about its axiomatics being based on a primitive concept of probability, independent of any interpretation about the nature of chance, are generally inaccurate and that (...) these errors in interpretation led to inadequate conceptual and epistemological approaches.

This paper presents a computational model of the way humans inductively identify and aggregate concepts from the low-level stimuli they are exposed to. Based on the idea that humans tend to select the simplest structures, it implements a dynamic hierarchical chunking mechanism in which the decision whether to create a new chunk is based on an information-theoretic criterion, the Minimum Description Length (MDL) principle. We present theoretical justifications for this approach together with results of an experiment in which participants, exposed (...) to meaningless symbols, have been implicitly encouraged to create high-level concepts by grouping them. Results show that the designed model, called hereafter MDLChunker, makes precise quantitative predictions both on the kind of chunks created by the participants and also on the moment at which these creations occur. They suggest that the simplicity principle used to design MDLChunker is particularly efficient to model chunking mechanisms. The main interest of this model over existing ones is that it does not require any adjustable parameter. (shrink)

The aim of this work is to investigate the factors promoting students’ engagement at school and supporting their well-being experience. According to the Positive Education there is a strong relationship between school environment and student’s well-being. Moreover, the quality of the school climate perceived by the students was found to influence engagement in school activities, as well. In this study, 153 students ( M = 67) attending 10th grade were presented with tests and questionnaires to assess individual assets (personality traits, (...) literacy skills), emerging appraisals (school-climate, well-being experience) and emerging actions (school engagement), according to the Student Well-Being Model. Path analysis showed that the best model does include neither individual assets nor direct effect of school climate on engagement, as the effect of school climate on engagement is mediated by well-being experience. The main result is that school climate has been confirmed as an important factor to be considered to improve engagement in school activities, but it is effective only when its influence can modify the well-being experience of the students. Moreover, the lack of significant effects of individual assets in the model suggests that improving school climate means to support well-being experience and, indirectly school engagement, irrespective to learning abilities and personality traits. This work encourages working in/with schools to implement positive education programs that support and sustain a positive school climate and culture for school-community wellbeing. (shrink)

Rapid Automatized Naming (RAN) is considered a universal marker of developmental dyslexia (DD) and could also be helpful to identify a reading deficit in minority-language children (MLC), in which it may be hard to disentangle whether the reading difficulties are due to a learning disorder or a lower proficiency in the language of instruction. We tested reading and rapid naming skills in monolingual Good Readers (mGR), monolingual Poor Readers (mPR), and MLC, by using our new version of RAN, the RAN-Shapes, (...) in 127 primary school students (from 3rd to 5th grade). In line with previous research, MLC showed, on average, lower reading performances as compared to mGR. However, the two groups performed similarly to the RAN-Shapes task. On the contrary, the mPR group underperformed both in the reading and the RAN tasks. Our findings suggest that reading difficulties and RAN performance can be dissociated in MLC; consequently, the performance at the RAN-Shapes may contribute to the identification of children at risk of a reading disorder without introducing any linguistic bias, when testing MLC.

ORCA.IT, a new online test of online research and comprehension was developed for the Italian population. A group of 183 students attending various types of upper secondary schools in Northern Italy were tested with the new tool and underwent further cognitive and neuropsychological assessment. The different school types involved in the study are representative of the school population in the Italian system, but can also be easily compared with the educational systems of other countries. The new test turned out to (...) have good psychometric properties after accurate item construction and final selection. In particular, Version 1 showed better characteristics than Version 2. Subsequently, comparison with one-way ANOVAs were performed to test whether differences exist between different school types, between groups with and without reading difficulties, and between males and females. Such differences are sometimes reported in the literature, but many remain controversial. Further, Pearson’s bivariate correlations were calculated to analyze associations between scores on the ORCA.IT and cognitive/neuropsychological variables. Finally, a stepwise regression analysis was performed on aggregated scores to identify the predictors of performance on each of the two versions, The test, especially in the most complete version (Version 1), appears to accurately and reliably capture students’ web searching abilities and online reading comprehension. The tool could highlight differences in online search and comprehension ability between students with and without reading difficulties, not penalizing overall performance but allowing very specific weaknesses to be pointed out. Further, it seems to be able to capture differences due to both educational pathways (different school types) and social attitudes (differences between males and females). Most interesting, it shows to be clearly resting on specific cognitive and neuropsychological abilities, including language, memory and attentional skills, which explain a large portion of the total variance. Offline text reading comprehension is a crucial predictor of online reading performance, while decoding ability is not. Prior knowledge also influences the results, as expected. The new tool turns out to be rather independent from previous internet experience and to measure more cognitively grounded processes related to information gathering, processing and communicating.

We study experimentally a coordination game with N heterogeneous individuals under different information treatments. We explore the effects of information on the emergence of Pareto-efficient outcomes, by means of a gradual decrease of the information content provided to the players in successive experiments. We observe that successful coordination is possible with private information alone, although not on a Pareto-optimal equilibrium. Reinforcement-based learning models reproduce the qualitative trends of the experimental results.

En la historia intelectual de América Latina existe una laguna respecto a la producción de las mujeres en el género de ensayo. Son los ensayos de identidad criolla, de hechura masculina, los que construyen el canon respecto a las temáticas y a las maneras de ser abordado. Los ensayos de género que las escritoras han realizado se articulan como respuesta a esta visión dominante de los procesos sociales, políticos y culturales de los países latinoamericanos. Revelan un fuerte descontento con la (...) construcción de la identidad femenina, una preocupación por la construcción de una ciudadanía plena y representan una respuesta a las demandas sociales políticas y culturales de las mujeres y otros grupos marginales. Las intelectuales debatieron, discutieron y polemizaron con las propuestas que al respecto portaban los discursos dominantes y el ensayo de género se vuelve el “arma de combate”. Lo que aquí se presenta, tiene como objetivo la recuperación de este corpus de conocimiento en la historia literaria de Cuba, Puerto Rico y República Dominicana. Una labor de arqueología literaria de temas, obras y autoras a partir del siglo XX. Se brinda, a partir del libro Mujeres ensayistas del Caribe Hispano: Hilvanando el silencio (2007) deAnna Freire Ashbaugh, Lourdes Rojas y Raquel Romeu, una visión panorámica del conjunto de ensayistas de cada país. Otras investigadoras como Catharina Vallejo, Ivette Sóñora, Carmen Dolores Hernández y Consuelo Meza Márquez ampliaran ese corpus y señalan algunos rasgos temáticos de la obra ensayística de autoras como Luisa Campuzano, Mirta Yáñez, Nara Araujo, Marta Núñez Sarmiento y Zaida Capote Cruz de Cuba; Concha Meléndez, Rosario Ferré, Norma Valle Ferrer, Nara Negrón Marreño y Silvia Álvarez Curbelo de Puerto Rico; y, de República Dominicana, Camila Henríquez Ureña, Carmita Landestoy, Carmen Durán y Rosa Inés Curiel Pichardo.

Concept of ethics in Ādi-Granth, Sikh canon.

At least for those who uphold the rationality of morality, ethics and practical reason are not two distinct topics: an ethically sound agent is one whose practical reason functions as it should. Take, for instance, the greatest historical figures. Aristotle claimed that no virtue of character can exist without practical wisdom—the excellence of practical, deliberative reason. And Kant thought that the categorical imperative, the ultimate moral principle that governs a good will, was at the same time the fundamental principlof practical (...) reasoning because the will simply ispractical reason. Even before any philosophical theory of the connection between acting well and the exercise of a rational power is in view, our moral practices strongly suggest that there is one. For we take it for granted that, in an important range of cases, when an agent fails to act as she should, something has gone awry with the agent and not just with her acts, and, furthermore, that the agent herself may be held responsible for this. In calling an agent who acts unethically "irrational," we are saying these two things. (shrink)

Estudio sistemático sobre la imagen y sus complejas relaciones con el lenguaje verbal, partiendo de una crítica al logocentrismo en su vertiente racionalista -que reduce el conocimiento y el pensamiento al discurso lingüístico- para desembocar en una teoría de la representación. El autor sostiene que la imagen va más allá de la representación al tornarse presencia, basándose en el examen de pensadores clásicos y teóricos actuales que han abordado cuestiones afines. Propone una teoría de la imagen que no se ciñe (...) sólo a lo visual, sino que reconoce las dimensiones no visuales de lo imaginal: "el principal objetivo de este libro es contribuir a la construcción de una filosofía de la imagen. Hoy en día es ya una necesidad urgente contar con un aparato conceptual que nos permita afrontar las distintas modalidades de lo imaginal, que aparecen en ámbitos tan diversos como la intimidad psicológica, la ciencia, la filosofía, la comunicación masiva, la religión, la educación, la propaganda o el arte".
