In the digital age, the global software development sector has been a forerunner in implementing new ways and configurations for remote teamwork using information and communication technologies on a widespread basis. Crises and technological advances have influenced each other to bring about changes in the ways of working. In the 70’s of the last century, in the middle of the so-called oil crisis, the concept of teleworking was defined using remote computer equipment to access office equipment and thus avoid moving (...) around using traditional vehicles. Then from the 90s, with the advent of communications and the widespread use of the Internet, the first virtual work teams were implemented in software development companies that already had some of the important characteristics needed to work in this way, such as, cultural diversity, characterized tasks, geographical distribution of members, communication, interdependence of tasks, leadership, cohesion, empowerment, confidence, virtuality. This manuscript groups the main factors into different models proposed by the literature and also analyzes the results of a study conducted in the midst of the Covid-19 crisis on 317 software development teams that had to work in virtual teams. The results of the quantitative methodology with structural equation modeling based on variance using the partial least squares route method are analyzed. The results of the research focus on some determinants that can directly affect the performance of the virtual team. A first determinant is communication in relation to the tasks. The second is trust in relation to leadership, empowerment and cohesion. The results of virtual teams provide information that can serve as a basis for future research lines for the implementation of virtual work strategies in post-pandemic work. (shrink)

This paper seeks to highlight the methodological contributions developed by Michel Foucault in regard to a critical history. We propose a tour through various passages of the thinker´s work, with the aim of bashing the main elements that allegedly make up his method. From this exercise we maintain that, in order to record the existence of a Foucauldian method, it is necessary to reproblematize this notion beyond the displacements around the well-known three moments of his work -archeological/genealogical/ethical-, reorienting the look (...) towards the critical tension possible to peer around the unique place that occupies the question of history in his work. The novelty of our proposal is to point out that, beyond the well-known substantial contributions foreshadowed around Foucault's conceptual rig, his work must be understood as an eminently practical historical-philosophical methodology, aimed at disarticulating the canonical principles that legitimize knowledge produced by the historiographic method, thus opening a region of indiscernibility and rarity in historical practice that, we maintain, can be thought of in the vicinity of a parahistory. In sum, we propose the thesis that the displacement in Foucault's work takes on a singular power from the introduction of a strategic artifice ― anonymous ―, aimed at forcing a fold of history on itself, showing how historiographical plots actively tax to sustain and legitimize the regimes of knowledge, power and truth present in them.

Diversas evidencias parecen indicar que, durante la comprensión oral, el procesamiento del habla se realiza a partir de la información verbal auditiva y de la información viso-gestual proveniente del interlocutor. En este marco, se evaluó el tiempo y la precisión de respuestas de sujetos oyentes en una tarea de lectura labial con el patrón acústico suprimido. En ella, 25 participantes adultos, sin diagnóstico de patologías lingüísticas o cognitivas ni discapacidad auditiva o visual, debían distinguir si estaban frente a una palabra (...) del español a partir de la visualización de su articulación. Para la tarea se construyeron 240 estímulos, divididos en tres grupos de 80 ‘Palabras’ del español, 80 ‘Pseudopalabras’ del español y 80 ‘No-Palabras’, presentados en forma aleatoria. Los resultados respecto del tiempo de respuesta indicaron que las ‘Palabras’ (m=717,6ms) se reconocen con una velocidad menor que las ‘Pseudopalabras’ (m=809,5ms) y las ‘No-Palabras’ (7633,7ms); mientras que las ‘Pseudopalabras’ demoraron más en ser respondidas que las ‘No-Palabras’. Por su parte, en los resultados de precisión los estímulos presentaron el siguiente patrón de reconocimiento: ‘Palabras’<‘Pseudopalabras’<‘No-Palabras’ (correspondientes a un 59,89%, 62,5% y 86,3%, respectivamente). Del mismo modo, se encontró evidencia robusta de la relación entre el tipo de estímulo presentado y el acierto/desacierto de las respuestas, aunque el modelo indica que la condición ‘No-Palabra’ es reconocida con mayor facilidad y que la diferencia entre ‘Palabras’ y las ‘Pseudopalabras’ no es relevante. Asimismo, se observó una relación entre la menor velocidad y el desacierto en las respuestas. Estos datos corroboran la hipótesis de la integración de información proveniente de la percepción visual y el procesamiento del lenguaje, al mismo tiempo que permiten proyectar trabajos futuros con evidencias electrofisiológicas.

The purpose of this study is to examine how workgroup diversity can be managed through specific strategic human resource management systems. Our review shows that ‘affirmative action’ and traditional ‘diversity management’ approaches have failed to simultaneously achieve business and social justice outcomes of diversity. As previous literature has shown, the benefits of diversity cannot be achieved with isolated interventions. To the contrary, a complete organizational culture change is required, in order to promote appreciation of individual differences. The paper contributes to (...) this discussion by exploring the implications of this change for human resource management, and explaining how the systems of practices should be changed when they are directed to diverse groups. The model designed to test this notion includes: (1) demographic and human capital diversity as independent variables, (2) group performance (measured as innovation outcomes) as the dependent variable and, (3) the orientation of the strategic human resource management system as a potential moderator of this relationship. The main conclusion of the empirical analysis developed is that different patterns of human resource management practices can be used, depending on the type of diversity that the organization faces, and the specific effects that it wishes to manage. Concretely, three alternative management systems are identified in this paper, with different moderating effects. This result has interesting implications for human resource management professionals, explained in the last section. The limitations of this study are also discussed, as well as some issues that future research in this field should address. (shrink)

In this paper we present a semantic analysis of the application of didactic constructivism to chemical education. We show that the psychological basis of constructivism yield, when applied to chemistry, an internalist semantics for the chemical names. Since these names have been presented as typical examples of an externalism for kind terms, a fundamental incompatibility ensues. We study this situation, to conclude that it affects chemical education at every level. Finally, we present a preliminary analysis of this problem from the (...) point of view of physics. (shrink)

A pesar de las «discrepancias radicales» entre ambos autores, este ensayo muestra cómo fueron leídas e interpretadas las Reflexiones sobre la violencia de G. Sorel por Ortega y Gasset. Sin embargo, una mirada crítica nos ofrece cómo el éthos orteguiano y el recurso a la huelga de G. Sorel son estructuras distintas, pero convergentes en sus filosofías. Asimismo descubrimos la misma reflexión en torno al cristianismo y al Renacimiento como metáforas culturales para comprender el desarrollo vital de la razón histórica (...) en épocas de crisis como las que vivieron los dos pensadores.

El autor de este trabajo expone un diagnóstico crítico de Europa apoyándose en la lectura de tres libros diferentes. El triunfo del nihilismo se levantaría, a su juicio, sobre el olvido de tres fundamentos íntimamente conectados entre sí: la Filosofía, el Cristianismo y Europa.

Open peer commentary on the article “Constructivist Model Building: Empirical Examples From Mathematics Education” by Catherine Ulrich, Erik S. Tillema, Amy J. Hackenberg & Anderson Norton. Upshot: I argue that radical constructivism poses a series of deep methodological constraints on educational research. We focus on the work of Ulrich et al. to illustrate the practical implications of these constraints.

El presente texto busca desarrollar una reflexión filosófica respecto de las posibles relaciones entre la noción de identidad y las formas de gobierno contemporáneas. A partir de un breve análisis sobre los principales desarrollos de la noción, se busca tensionar el campo de comprensión habitual y plantear un determinado modo en que esta puede pensarse como un engranaje epistemológico-ético respecto de los modos en que los individuos son llamados a nombrarse y reconocerse dentro de los límites impuestos por una cartografía (...) política. La tesis que sostiene este escrito dice relación con que la categoría de individuo moderno no es sostenible sin una adscripción a un orden de los nombres que tiende al autogobierno en base a la apelación de un ideal ético de correspondencia consigo mismo.

I put forward an inferentialist account of Lewis structures (LSs). In this view, the role of LSs is not to realistically depict molecules, but instead to allow surrogate reasoning and inference in chemistry. I also show that the usage of LSs is a central part of a person’s identity as a chemist, as it is defined within educational identity theory. Taking these conclusions together, I argue that the inferentialist approach to LSs and chemistry identity theory can be studied in parallel, (...) as two complementary sides of the same research programme.

Esta presentación permite al lector tener pleno conocimiento de la interpretación que los obispos hicieron de los acontecimientos históricos de la época. Por último, se añaden algunas observaciones críticas para comparar las ideas de los (...) obispos sobre los laicos con la doctrina del Concilio. (shrink)

We argue for an account of chemical reactivities as chancy propensities, in accordance with the ‘complex nexus of chance’ defended by one of us in the past (Suárez, 2017, 2020). Reactivities are typically quantified as proportions, and an expression such as “A + B → C” does not entail that under the right conditions some amounts of A and B react to give the amount of C that theoretically would correspond to the stoichiometry of the reaction. Instead, what is produced (...) is a fraction α < 1 of this theoretical amount, and the corresponding percentage is usually known as the yield, which expresses the relative preponderance of its reaction. This is then routinely tested in a laboratory against the observed actual yields for the different reactions. Thus, on our account, reactivities ambiguously refer to three quantities at once. They first refer to the underlying propensities effectively acting in the reaction mechanisms, and which in ‘chemical chemistry’ (Schummer, 1998) are commonly represented by means of Lewis structures. Besides, reactivities represent the probabilities that these propensities give rise to, for any amount of the reactants to combine as prescribed. This last notion is hence best understood as a single case chance and corresponds to a theoretical stoichiometric yield. Finally, reactivities represent the actual yields observed in experimental runs, which account for and provide the requisite evidence for / against both the mechanisms and single case chances ascribed.

Does the board of directors influence cost of debt financing? This study of a sample of Spanish listed companies during the period 2004-2007 provides some evidence about the question. The results suggest that two board attributes - director ownership and board activity - appear to influence in the risk assessment of debtholders because of their ability to reduce agency cost and information asymmetry. We also find a non-linear relationship between board size and cost of debt, suggesting that from certain levels (...) the benefits of large boards may be outweighed by the cost of poorer communication and increased decision-making time.
