Learning Management System (LMS) platforms provide a wealth of information on the learning patterns of students. Learning Analytics (LA) techniques permit the analysis of the logs or records of the activities of both students and teachers on the on-line platform. The learning patterns differ depending on the type of Blended Learning (B-Learning). In this study, we analyse: (1) whether significant differences exist between the learning outcomes of students and their learning patterns on the platform, depending on the type of B-Learning (...) [Replacement blend (RB) vs. Supplemental blend (SB)]; (2) whether a relation exists between the metacognitive and the motivational strategies (MS) of students, their learning outcomes and their learning patterns on the platform. The 87,065 log records of 129 students (69 in RB and 60 in SB) in the Moodle 3.1 platform were analyzed. The results revealed different learning patterns between students depending on the type of B-Learning (RB vs. SB). We have found that the degree of blend, RB vs. SB, seems to condition student behavior on the platform. Learning patterns in RB environments can predict student learning outcomes. Additionally, in RB environments there is a relationship between the learning patterns and the metacognitive and (MS) of the students. (shrink)

Inauguration speech at chair number 18 of the Brasilian Academy of Philosophy.

This article explores the metaphor of Science as provider of sharp images of our environment, using the epistemological framework of Objective Cognitive Constructivism. These sharp images are conveyed by precise scientific hypotheses that, in turn, are encoded by mathematical equations. Furthermore, this article describes how such knowledge is pro-duced by a cyclic and recursive development, perfection and reinforcement process, leading to the emergence of eigen-solutions characterized by the four essential properties of precision, stability, separability and composability. Finally, this article discusses (...) the role played by ontology and metaphysics in the scientific production process, and in which sense the resulting knowledge can be considered objective.

Las confesiones de Tauber han recorrido varios continentes desde el año 1997 y aseguraría que han sido leídas por muchos médicos. Tienen características que las hacen muy atractivas para las personas que hemos elegido la medicina como parte de nuestra vida: historias clínicas y relatos de la práctica profesional. Y, además y sobre todo, el autor se empeña en diagnosticar y curar el cuerpo herido y el alma enferma de la Medicina, planteándose con pasión todas las posibilidades que ofrezcan esperanza. (...) Hay búsqueda de causas, de hipótesis explicativas, de referencias ilustradas y humanistas y del auxilio de los que más saben. Todo para llegar a un diagnóstico y a un plan terapéutico: alivio de los síntomas, posibilidades de curación o de regeneración saludable para favorecer el buen funcionamiento presente y futuro. Ya no será igual, pero no tiene porqué ser peor. El tratamiento y la rehabilitación serán duros y todavía son experimentales, pero están bien fundamentados. .. (shrink)

Higher education in the 21st century faces the challenge of changing the way in which knowledge is conveyed and how teachers and students interact in the teaching-learning process. The current pandemic caused by SARS-CoV-2 has hastened the need to face up to this challenge and has furthered the need to approach the issue from the perspective of digitalisation. To achieve this, it is necessary to design training programmes geared towards teaching staff and which address both the use of technology and (...) instructional design aimed at promoting the development of self-regulated learning and automatic feedback systems. In this study, work was carried out with 23 teachers in a training programme conducted through Moodle. The aims were: to test whether there were any significant differences between the behaviour patterns of new teachers compared to experienced teachers, to determine whether clusters of behaviour patterns corresponded to the type of teacher and to ascertain whether the level of teacher satisfaction with the training activity in digital teaching will depend on the type of teacher. A quantitative as well as a qualitative design was applied. Differences were found in the behaviour patterns in the training activities for the development of rubrics and use of learning analytics systems in virtual learning environments. It was also found that the type of teacher did not correspond exactly to the behaviour cluster in the learning platform. In addition, no significant differences were found in the level of satisfaction between the two kinds of teacher. The main contribution this study makes is to provide a detailed description of the training stage as well as the materials required for its repetition. Further analytical studies are required on teacher perception of training programmes in digital teaching in order to provide personalised training proposals that lead to an effective use of teaching in digital environments.

An Andalusian tradition of zījes seems to have been predominant in the Maghrib due to the popularity of the zīj of Ibn Is[hdotu]āq al-Tūnisī and derived texts compiled in the fourteenth century. This tradition computed sidereal planetary longitudes and allowed the calculation of tropical longitudes by using trepidation tables based on models designed in al-Andalus by Abū Is[hdotu]āq ibn al-Zarqālluh. This tradition also used Ibn al-Zarqālluh's model to calculate the obliquity of the ecliptic, which implied that this angle had a (...) cyclical period of oscillation between a maximum of 23;53° and a minimum of 23;33°: after reaching this minimum value the obliquity of the ecliptic was bound to increase. This paper argues that some new Maghribi sources give information on observations made in the Maghrib in the fourteenth and beginning of the fifteenth centuries that imply that precession had increased beyond the limits allowed by the Zarqāllian trepidation theory, while the obliquity of the ecliptic had diminished below the level accepted by astronomers who followed Ibn al-Zarqālluh. This explains the introduction in the Maghrib of Eastern zījes, which computed directly tropical longitudes and did not accept the cyclical variation of the obliquity. Information about observations of dawn and twilight made both in Egypt and in the Maghrib in the fourteenth and fifteenth centuries is also presented. (shrink)

This paper investigates some classical oppositional categories, like synthetic versus analytic, posterior versus prior, imagination versus grammar, metaphor versus hermeneutics, metaphysics versus observation, innovation versus routine, and image versus sound, and the role they play in epistemology and philosophy of science. The epistemological framework of _objective cognitive constructivism_ is of special interest in these investigations. Oppositional relations are formally represented using algebraic lattice structures like the cube and the hexagon of opposition, with applications in the contexts of modern color theory, (...) Kantian philosophy, Jungian psychology, and linguistics. (shrink)

Los textos de este libro, escritos entre 2006 y 2010, están vinculados por un tema común: la conjunción Humanidades-Universidad. Los autores presentan aquí una parte del proceso de investigación –que se realiza en el Instituto de Investigaciones Sociales de la UNAM– cuyo eje ha girado alrededor del problema de la definición contemporánea de Universidad como institución educativa formadora de cultura y su relación intrínseca con las Humanidades, en una dirección más específica, buscan mostrar la continuidad de las palabras que definen (...) lo humano, a través de un léxico que ha perdurado en la definición y quehacer de la institución universitaria, específicamente de la UNAM. Las correspondencias y cruces necesarios entre las evidencias teóricas y empíricas en este trabajo permiten un abanico de lecturas desde las cuales se posibilitan diversas interpretaciones problemáticas de la institución. Los temas y problemas abordados resultan de sumo interés para la comunidad universitaria, en especial para los académicos universitarios en cuyas manos se realiza cotidianamente el fin formativo de la Universidad. De la misma manera, este libro constituye un excelente material de apoyo para la formación de comunicólogos: en el sentido de contrastar las teorías desde la perspectiva de un estudio concreto, y con ello, arrojar luz sobre la investigación de diversos fenómenos comunicativos.

This article explores some open questions related to the problem of verification of theories in the context of empirical sciences by contrasting three epistemological frameworks. Each of these epistemological frameworks is based on a corresponding central metaphor, namely: (a) Neo-empiricism and the gambling metaphor; (b) Popperian falsificationism and the scientific tribunal metaphor; (c) Cognitive constructivism and the object as eigen-solution metaphor. Each of one of these epistemological frameworks has also historically co-evolved with a certain statistical theory and method for testing (...) scientific hypotheses, respectively: (a) Decision theoretic Bayesian statistics and Bayes factors; (b) Frequentist statistics and p-values; (c) Constructive Bayesian statistics and e-values. This article examines with special care the Zero Probability Paradox (ZPP), related to the verification of sharp or precise hypotheses. Finally, this article makes some remarks on Lakatos’ view of mathematics as a quasi-empirical science. (shrink)

O pensamento político de Francisco Pinto da Cunha Leal (1880-1970) sofreu uma constante evolução ao longo da sua vida pública. A emergência do Estado Novo, nos anos 30 e 40 do século XX, tornou-o num oposicionista, levando-o a denunciar as suas violências e a desconstruir os seus mitos numa intransigente defesa da democracia. Nos inícios dos anos 60, confrontado com as novas realidades políticas, nascidas da Guerra Fria (1947-1991) e da crise do sistema colonial português (1961), aproveitando a relativa tolerância (...) do Salazarismo a nível editorial, esforça-se por fornecer, nos livros que publica, uma alternativa democrática ao pensamento dominante. O presente texto procura analisar a sua reflexão política numa época caracterizada pelo aparecimento de uma nova geração de contestatários do regime. (shrink)

El texto reflexiona sobre el vaciamiento neoliberal de la política, despolitizando la vida y cuantificando la realidad. El neoliberalismo enaltece la libertad individual, llevando a un individualismo extremo que amenaza el tejido social. La destrucción creativa moldea cuerpos y subjetividades, promoviendo competencia y autosacrificio. La exterioridad neoliberal afecta a los individuos, enfocándolos en su propia libertad y bloqueando su capacidad de actuar con otros. La crítica se centra en recuperar la sensibilidad y el deseo para restaurar la vida colectiva, explorando (...) la relación entre el cuerpo entristecido y la lógica neoliberal de acumulación y autorresponsabilidad, sugiriendo que puede generar cuerpos tristes y descontentos -todo esto en atención a una ontología spinozista-. Se critica, así, el culto a la vida en la sociedad neoliberal y cómo se marginaliza a los cuerpos vulnerables, abogando por abrazar la vulnerabilidad y la interdependencia para superar la lógica destructiva y la obsesión por la acumulación.

The Shannon information function (H) has been extensively used in ecology as a statistic of species diversity. Yet, the use of Shannon diversity index has also been criticized, mainly because of its ambiguous ecological interpretation and because of its relatively great sensitivity to the relative abundances of species in the community. In my opinion, the major shortcoming of the traditional perspective (on the possible relation of species diversity with information theory) is that species need for an external receiver (the scientist (...) or ecologist) to exist and transmit information. Because organisms are self-catalized replicating structures that can transmit genotypic information to offspring, it should be evident that any single species has two possible states or alternatives: to be or not to be. In other words, species have no need for an external receiver since they are their own receivers. Therefore, the amount of biological information (at the species scale) in a community with one only species would be species, and not bits as in the traditional perspective. Moreover, species diversity appears to be a monotonic increasing function of (or S) when all species are equally probable (S being species richness), and not a function of as in the traditional perspective. To avoid the noted shortcoming, we could use 2H (instead of H) for calculating species diversity and species evenness (= 2H/S). However, owing to the relatively great sensitivity of H to the relative abundances of species in the community, the value of species dominance (= 1 − 2H/S) is unreasonably high when differences between dominant and subordinate species are considerable, thereby lowering the value of species evenness and diversity. This unsatisfactory behaviour is even more evident for Simpson index and related algorithms. I propose the use of other statistics for a better analysis of community structure, their relationship being: species evenness + species dominance = 1; species diversity × species uniformity = 1; and species diversity = species richness × species evenness.

Apresentar a sociologia e a filosofia frente a dimensão tomada pela informação, e seus usos na contemporaneidade, requer uma mirada sobre relações e interações em ambientes on-line chamados de virtuais ou digitais, como mídias e redes sociais. Com isso, ao pensar os estudos acerca do social e a dimensão de uma filosofia aplicada ao entendimento dessa mesma relação virtual/digital na internet, surgem indagações a ser exploradas de modo a se entender certas transformações pelas quais a sociedade atual tem passado. Dessa (...) forma, a partir de uma exposição de exemplos dessa interação, e transformação social, tornada digital, miro nos novos tipos de trabalhos (e trabalhadores), formas de argumentar acerca dos impactos dos usos dessas formas midiáticas digitalizadas de apropriação da realidade.

Durante décadas, los filósofos han concebido los derechos humanos como una clase de derechos naturales de los que gozamos por el mero hecho de ser seres humanos. Sin embargo, esta interpretación ha sido severamente cuestionada en los últimos años. Toda una familia de autores, identificados con una concepción “práctico-dependiente”, asevera que los derechos humanos constituyen una práctica sui generis completamente ajena a la tradición del derecho natural. En contra de esta postura, este artículo argumenta que el discurso de los derechos (...) naturales es parte constitutiva de la doctrina actual de los derechos humanos y que puede hacer un aporte crucial a la adecuada justificación y comprensión de sus funciones, su contenido y su alcance normativo. Más concretamente, mi tesis será que si bien los derechos humanos no pueden reducirse a derechos naturales, bien podrían derivar de derechos naturales previos. (shrink)

This study integrates corpus-assisted text analysis with frame semantics to study a social problem. Taking a cognitive-linguistic approach to critical discourse studies, in this article I examine the linguistic construction of minors in a corpus of 489 articles from the Uruguayan newspaper El País in the context of the so-called ‘Criminal Imputability Referendum’. Throughout, I focus on the construal operation of framing and identify a host of discursive patterns via which minors and adolescents are recurrently placed within the semantic frame (...) CRIME, and within this, they profile the frame elements of perpetrators of violent crimes rather than victims. I argue that, in the context of the referendum, these discursive strategies run the risk of facilitating the consolidation of a strong conceptual link whereby youth become readily associated with criminality, and are subservient to the political views of groups supporting a lower cut-off age for criminal responsibility and more stringent punishments. The observations arrived at in this instance set the foundations for a future experimental study testing whether the discursive patterns unearthed here have an effect on how readers conceptualize minors outside the texts.

Resumen:En este trabajo se explora la influencia del gerencialismo en las ciencias sociales en las universidades latinoamericanas. En particular, se observa cómo las estructuras y las prácticas de gestión afectan las labores académicas en esta área del conocimiento. Se plantea que el gerencialismo, con su énfasis en la eficiencia y la eficacia, limita el desarrollo de la diversidad teórica y metodológica en la disciplina, favoreciendo enfoques que son fácilmente medibles y, por lo tanto, más alineados con los indicadores de productividad (...) académica. A través de la teoría de Niklas Luhmann, este trabajo ofrece una comprensión de las universidades como sistemas de decisiones. Se analiza cómo estas instituciones gestionan la complejidad a través de programas regulatorios que ordenan sus decisiones en torno a fines específicos determinados por principios como la cuantificación y la burocratización. Finamente, se sugiere la necesidad de revisar los modelos actuales en el contexto de las ciencias sociales de las universidades latinoamericanas donde el pensamiento crítico y el compromiso con las problemáticas sociales deberían jugar un papel central en la definición de su quehacer.Palabras clave: educación superior; gerencialismo; ciencias sociales; Latinoamérica.

Los diversos intentos por conceptualizar el principio de precaución de manera general se construyen a partir de las respuestas que han encontrado los ordenamientos jurídicos, tanto estatales como de carácter internacional, para hacer frente a la incertidumbre que provoca la generación de los riesgos provenientes del desarrollo, especialmente frente a las nuevas tecnologías. De esta forma, se pueden encontrar importantes lecciones en la historia respecto al cómo afrontar situaciones que dañan, principalmente, al medioambiente, la salud humana, animal o vegetal; por (...) lo cual es importante conocer como éstos se han ido enfrentando y fueron dando forma a este principio en la práctica, el cual tiene una importancia fundamental al convertirse en una garantía frente al progreso de las ciencias, para que no sea más caro el “prevenir que curar”.

El concepto de infinito en Descartes hace referencia a las categorías desubstancia y cantidad, por eso difiere del de la teoría moderna del continuomatemático, relativo a la de cualidad. El cartesianismo se soporta en eseinfinito que equivale a Dios, cuya demostración lo supone, y luego explicael cogito como consecuencia de Dios, así mismo explica el mundo y suinteligibilidad. La vida humana es sui generis porque transcurre entre lofinito y lo infinito inabarcable, también se realiza según la necesidad y segúnla libertad. (...) Esta visión del hombre convoca a Descartes a buscar la verdadcon el propósito práctico de vivir lo mejor que se pueda. (shrink)

El déjà vu es problemático en el fin de siglo (XIX), no por la ensoñación poética que trae consigo, sino por la perturbación que le causa a la vida. De allí la preocupación de los “savants” por entenderlo, controlarlo y “curarlo”. El déjà vu irrumpe en la vida cotidiana del sujeto, lo perturba, lo desconcierta. De allí que Bodei lo relacione con el eterno retorno de Nietzsche. Más que un caso aislado o “patológico” ligado a individuos “pa(de)cientes” como los epilépticos, (...) o una “válvula de escape de la realidad”, el déjà vu sería para Bodei, la irrupción (la erupción) de una ilusión frente a la realidad “operante”. El déjà vu pone en crisis la supuesta identidad “absoluta” del sujeto, su dimensión del tiempo y su “confianza” en la continuidad de la personalidad. Para hablar de él es necesario, como sugiere Bodei, referirse al tema del “doble” en la literatura del siglo XIX. (Dostoievski más que Stevenson). (shrink)
