This study tested a structural model of cognitive-emotional explanatory variables to explain performance in mathematics. The predictor variables assessed were related to students’ level of development of early mathematical competencies (EMCs), specifically, relational and numerical competencies, predisposition toward mathematics, and the level of logical intelligence in a population of primary school Chilean students (n = 634). This longitudinal study also included the academic performance of the students during a period of four years as a variable. The sampled students were initially (...) assessed by means of an Early Numeracy Test (ENT), and, subsequently, they were administered a Likert-type scale to measure their predisposition toward mathematics (EPMAT) and a basic test of logical intelligence (TILE). The results of these tests were used to analyse the interaction of all the aforementioned variables by means of a structural equations model. This combined interaction model was able to predict 64.3% of the variability of observed performance. Preschool students' performance in EMCs was a strong predictor for achievement in mathematics for students between 8 to 11 years of age. Therefore, this paper highlights the importance of EMCs and the modulating role of predisposition toward mathematics. Also, this paper discusses the educational role of these findings, as well as possible ways to improve negative predispositions toward mathematical tasks in the school domain. (shrink)

Este artículo propone una relectura de Escritura de Raimundo Contreras de Pablo de Rokha. El objetivo es encontrar huellas de la presencia y referencialidad del sujeto de la enunciación al interior del discurso que él mismo produce, o sea, evidenciar aquellas marcas textuales que permiten comprender cómo en Escritura emerge un sujeto de la enunciación que torna inestables los límites de la primera persona singular. De manera específica, propongo poner atención en los modelos de configuración identitaria que despliega el sujeto (...) de la enunciación: ¿A través de qué estrategias retóricas este sujeto enuncia su yo? La identificación de tales estrategias permitirá determinar las implicaciones ideológicas y los juicios éticos que subyacen la escritura rokhiana de las primeras décadas del siglo pasado. (shrink)

Clathrin and the endocytosis machinery has recently been described as being required in mammalian cells for the internalization of large particles including pathogenic bacteria, fungi, and large viruses. These apparently unexpected observations, within the framework of the classical mechanisms for the formation of clathrin‐coated vesicles, are now considered as examples of a new non‐classical function of clathrin, which can promote the internalization of membrane domains associated to planar clathrin lattices. The role of actin downstream of clathrin seems to be critical (...) for this still poorly characterized process. The historical frontier between endocytosis and phagocytosis is vanishing in the light of this new role for clathrin. (shrink)

This set includes notebooks 1 through 8 with (...) all attendant notes and materials and is an indispensible resource for scholars in the humanities and social sciences. (shrink)

We propose a nonmonotonic Description Logic of typicality able to account for the phenomenon of combining prototypical concepts, an open problem in the fields of AI and cognitive modelling. Our logic extends the logic of typicality ALC + TR, based on the notion of rational closure, by inclusions p :: T(C) v D (“we have probability p that typical Cs are Ds”), coming from the distributed semantics of probabilistic Description Logics. Additionally, it embeds a set of cognitive heuristics for concept (...) combination. We show that the complexity of reasoning in our logic is EXPTIME-complete as in ALC. (shrink)

EL SECTOR SALUD EN LA ARGENTINA DE LOS '90. CONTROVERSIAS ACERCA DE LAS OBRAS SOCIALES SINDICALES.

The paper introduces an extension of the proposal according to which conceptual representations in cognitive agents should be intended as heterogeneous proxytypes. The main contribution of this paper is in that it details how to reconcile, under a heterogeneous representational perspective, different theories of typicality about conceptual representation and reasoning. In particular, it provides a novel theoretical hypothesis - as well as a novel categorization algorithm called DELTA - showing how to integrate the representational and reasoning assumptions of the theory-theory (...) of concepts with the those ascribed to the prototype and exemplars-based theories.

This essay examines the problems associated with the installation of a precision instrument at the National Astronomical Observatory of Chile, starting before its construction and following the process through its installation to its later useful life. Between 1908 and 1913, the director of the observatory, Friedrich W. Ristenpart, corresponded with the German manufacturer, A. Repsold & Söhne in Hamburg, trying to identify the critical points pertinent to the installation of the instrument in Chile. These communications reveal how the installation of (...) the instrument required the stabilization of local knowledge (location, adjustment, calibration, and staging) that would allow the data it obtained to be universally validated. This correspondence between user and manufacturer also reveals that the phenomenon of the mobility of instruments implies much more than simply transporting something from one place to another: there is no movement without some type of coordination between the extraction of an object from a certain place and context and its insertion into a new place and set of relationships.

The following presents an excerpt from Nishitani Keiji’s “Prajña and Reason” (1979), which can be considered Nishitani’s last attempt to make his case for the importance of the “standpoint of śūnyatā (‘emptiness’)” in confrontation with the history of Western philosophy. The translator’s preface situates “Prajña and Reason” (1) in Nishitani’s oeuvre and (2) in the context of his broader reception of Western thought, before (3) outlining the place of the excerpt within the full study. The translation here excerpts section six (...) and a portion of the final section seven. Where the prior sections develop and motivate his unified interpretation of G. W. F. Hegel (from the Differenzschrift to the Encyclopedia), in this excerpt, Nishitani diagnoses a problem in the relationships between the domains of Absolute Spirit, specifically, philosophy and religion. As argued in the translator’s preface, the arch of this study points to the contributions that religion (and art) make in evincing “living activity,” a “Knowing” that, while perhaps “un-Scientific” and, in that way, a “not-Knowing,” is for all that “Truthful.”.

Scientists are rapidly mapping the chemical and physical pathways that constitute biological systems, making the complexity of processes such as inheritance, development, evolution, and even the origin of life increasingly tractable. Through genetics and neuroscience, biological understanding is now being extended deeply into the human sciences and has begun to transform our understanding of behavior, mind, culture, and values. The idea of a science-driven unity of knowledge has reemerged in several forms in both reductionist and nonreductionist frameworks. This volume examines (...) some of the extraordinary empirical discoveries that have caused a revival of this idea and presents theories from thinkers in a variety of disciplines, including E. O. Wilson, Eric Kandel, and Elaine Scarry. (shrink)

The publication of this book is an event in the making. All over the world scientists, psychologists, and philosophers are waiting to read Antonio Damasio's new theory of the nature of consciousness and the construction of the self. A renowned and revered scientist and clinician, Damasio has spent decades following amnesiacs down hospital corridors, waiting for comatose patients to awaken, and devising ingenious research using PET scans to piece together the great puzzle of consciousness. In his bestselling Descartes' Error, (...) Damasio revealed the critical importance of emotion in the making of reason. Building on this foundation, he now shows how consciousness is created. Consciousness is the feeling of what happens-our mind noticing the body's reaction to the world and responding to that experience. Without our bodies there can be no consciousness, which is at heart a mechanism for survival that engages body, emotion, and mind in the glorious spiral of human life. A hymn to the possibilities of human existence, a magnificent work of ingenious science, a gorgeously written book, The Feeling of What Happens is already being hailed as a classic. (shrink)

Antonio Gramsci (1891--1937) was one of the most original political thinkers in Western Marxism and an exceptional intellectual. Arrested and imprisoned by the Italian Fascist regime in 1926, Gramsci died before fully regaining his freedom, yet he wrote extensive letters while incarcerated, rich with insight into the physical and psychological tortures of prison. In meticulous detail, Gramsci records how political prisoners, himself included, contend with the fear of illness and death and the rules and regulations that threaten to efface (...) their individuality. Forming an incomparable link between Gramsci's intellectual passion and his emotional vulnerability, _Letters from Prison_ shows a man reconstructing his life while being separated from it, struggling to recapture the primary relationships that once defined his identity. Frank Rosengarten divides more than four hundred Gramsci letters into two companion volumes, complete with a chronology of the thinker's crucial life experiences, biographical notes on his correspondents, and a bibliography of works cited in his letters.

Antonio Negri, one of the world's leading scholars on Baruch Spinoza (1632-1677) and his contemporary legacy, offers a straightforward explanation of the philosopher's elaborate arguments and a persuasive case for his ongoing relevance. Responding to a resurgent interest in Spinoza's thought and its potential application to contemporary global issues, Negri demonstrates the thinker's special value to politics, philosophy, and related disciplines. Negri's work is both a return to and an advancement of his initial affirmation of Spinozian thought in _The (...) Savage Anomaly_. He further defends his understanding of the philosopher as a proto-postmodernist, or a thinker who is just now, with the advent of the postmodern, becoming contemporary. Negri also connects Spinoza's theories to recent trends in political philosophy, particularly the reengagement with Carl Schmitt's "political theology," and the history of philosophy, including the argument that Spinoza belongs to a "radical enlightenment." By positioning Spinoza as a contemporary revolutionary intellectual, Negri addresses and effectively defeats twentieth-century critiques of the thinker waged by Jacques Derrida, Alain Badiou, and Giorgio Agamben.

It has been suggested that due to AI-technology-generated gadgets, a digital unconscious enables the probable annulment of the Freudian unconscious. The purpose of this article is to delve into Freudian topography as a way to demonstrate that this foreclosure of the unconscious was somewhat present in Freud as of 1920. In addition, regardless of solid attempts at the extinction of the unconscious by contemporary demands, I will focus on how the capitalist discourse and AI-generated technology propose a different form of (...) social bond. Finally, the conceptualization of pain (_Schmerz_) is important for ascribing a different modality to the Freudian unconscious than in recent dissertations, but most importantly, it is a significant element for analytical experience to function properly where it must not be aligned with suffering. An era without an unconscious may foretell a time where enjoyment, as a form of subjectivity, is effaced. (shrink)

This article addresses an open problem in the area of cognitive systems and architectures: namely the problem of handling (in terms of processing and reasoning capabilities) complex knowledge structures that can be at least plausibly comparable, both in terms of size and of typology of the encoded information, to the knowledge that humans process daily for executing everyday activities. Handling a huge amount of knowledge, and selectively retrieve it according to the needs emerging in different situational scenarios, is an important (...) aspect of human intelligence. For this task, in fact, humans adopt a wide range of heuristics (Gigerenzer & Todd) due to their “bounded rationality” (Simon, 1957). In this perspective, one of the requirements that should be considered for the design, the realization and the evaluation of intelligent cognitively-inspired systems should be rep- resented by their ability of heuristically identify and retrieve, from the general knowledge stored in their artificial Long Term Memory (LTM), that one which is synthetically and contextually relevant. This requirement, however, is often neglected. Currently, artificial cognitive systems and architectures are not able, de facto, to deal with complex knowledge structures that can be even slightly comparable to the knowledge heuris- tically managed by humans. In this paper I will argue that this is not only a technological problem but also an epistemological one and I will briefly sketch a proposal for a possible solution. (shrink)

Endowing artificial systems with explanatory capacities about the reasons guiding their decisions, represents a crucial challenge and research objective in the current fields of Artificial Intelligence (AI) and Computational Cognitive Science [Langley et al., 2017]. Current mainstream AI systems, in fact, despite the enormous progresses reached in specific tasks, mostly fail to provide a transparent account of the reasons determining their behavior (both in cases of a successful or unsuccessful output). This is due to the fact that the classical problem (...) of opacity in artificial neural networks (ANNs) explodes with the adoption of current Deep Learning techniques [LeCun, Bengio, Hinton, 2015]. In this paper we argue that the explanatory deficit of such techniques represents an important problem, that limits their adoption in the cognitive modelling and computational cognitive science arena. In particular we will show how the current attempts of providing explanations of the deep nets behaviour (see e.g. [Ritter et al. 2017] are not satisfactory. As a possibile way out to this problem, we present two different research strategies. The first strategy aims at dealing with the opacity problem by providing a more abstract interpretation of neural mechanisms and representations. This approach is adopted, for example, by the biologically inspired SPAUN architecture [Eliasmith et al., 2012] and by other proposals suggesting, for example, the interpretation of neural networks in terms of the Conceptual Spaces framework [Gärdenfors 2000, Lieto, Chella and Frixione, 2017]. All such proposals presuppose that the neural level of representation can be considered somehow irrelevant for attacking the problem of explanation [Lieto, Lebiere and Oltramari, 2017]. In our opinion, pursuing this research direction can still preserve the use of deep learning techniques in artificial cognitive models provided that novel and additional results in terms of “transparency” are obtained. The second strategy is somehow at odds with respect to the previous one and tries to address the explanatory issue by avoiding to directly solve the “opacity” problem. In this case, the idea is that one of resorting to pre-compiled plausible explanatory models of the word used in combination with deep-nets (see e.g. [Augello et al. 2017]). We argue that this research agenda, even if does not directly fits the explanatory needs of Computational Cognitive Science, can still be useful to provide results in the area of applied AI aiming at shedding light on the models of interaction between low level and high level tasks (e.g. between perceptual categorization and explanantion) in artificial systems.

Persuasive technologies can adopt several strategies to change the attitudes and behaviors of their users. In this work I synthesize the lessons learned from three empirical case studies on automated persuasion that have been carried out in the last decade in the contexts of: persuasive news recommendations, social robotics, and e-commerce, respectively. In particular, such studies have assessed, in the technological domain, the effects of nudging techniques relying on well known persuasive argumentation schemas and on framing strategies. In discussing the (...) main findings, I will argue that the obtained persuasive effects are due to the fact that such techniques leverage on cognitive mechanisms that refer to the “system 1” types of automatic processes hypothesized in the context of the dual process theory of reasoning. As a consequence of this state of affairs, any automated persuasive systems (used for ethical purposes: e.g. suggesting good health habits) should be able to re-use these types of system 1 strategies in order to gradually take the users in an argumentation territory where system 2 processes can take place. -/- .

This selection of papers is concerned with the history of linguistics in Spain, dealing with the evolution of linguistic ideas from the Middle Ages and the European context of the linguistic debates in Spain to the 20th century, concluding with Malkiel's appraisal of Ramón Menéndez Pidal (1869-1968). The volume includes papers on Antonio Nebrija and Sanctius, probably the best-known grammarians of the Iberian peninsula, but - as the other papers suggest - there is much more to be known about (...) the Spanish linguistic traditions. The papers in this volume were previously published in Historiographia Linguistica XI:1/2 (1984). (shrink)

Combining typical knowledge to generate novel concepts is an important creative trait of human cognition. Dealing with such ability requires, from an AI perspective, the harmonization of two conflicting requirements that are hardly accommodated in symbolic systems: the need of a syntactic compositionality (typical of logical systems) and that one concerning the exhibition of typicality effects (see Frixione and Lieto, 2012). In this work we provide a logical framework able to account for this type of human-like concept combination. We propose (...) a nonmonotonic Description Logic of typicality called TCL (Typicality-based Compositional Logic). (shrink)

Research on the use of smartphone apps with the aim of developing self-regulated learning and increasing academic performance of university students in virtual mode, as a result of the COVID-19 pandemic, is recent and scarce. The present article shows the results of a study that analyzed the effect of using the 4Planning app with an intra-curricular approach on SRL and on the academic performance of 119 1st-year psychology students in virtual mode, at a Chilean university. The research was conducted with (...) quantitative methodology and a quasi-experimental design, with pre- and posttest measurements of an experimental group and comparisons with three control groups. The results show that students who used the app during 10 weeks of the first academic semester 2021: increased SRL self-report, increased academic self-efficacy, and obtained higher academic performance, compared to those who did not use it. The above occurs because the 4Planning app activates functions of the self-regulatory system of goal-directed behavior, which allows exercising the capacity of self-direction and self-influence on this type of behavior in the particular context of academic performance, which produces SRL. It is concluded that the 4Planning app is effective in developing self-regulation and improving the academic performance of 1st-year university students, in virtual learning mode. (shrink)
