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)

We point out the need to clarify some of the ideas related to the connection between development and sustainability in the Report of the Open Working Group of the General Assembly on Sustainable Development. In particular, the meaning of ‘sustainable’ is not clear when applied to specific areas of human activity. A more detailed explanation of the kind of equality sought for in the proposal is also needed. Because of potential conflicts between goals, we miss some considerations on the impact (...) of population increase both on development and on sustainability. A distinction is made here between two kinds of goals included in the Report. Some of the proposed 17 goals can then be seen as ends in themselves, whereas others seem to be means for the first set. The two sets thereby established should be seen in theory and dealt with in practice in a differentiated manner. (shrink)

Con la finalidad de fundamentar y reforzar su teoría de los bienes primarios, J.Rawls introduce, en el §65 de Una teoría de la justicia, la idea de “principio aristotélico”.Se discuten las dificultades que implica aceptar dicha noción, así como las limitaciones de la idea de bien que subyace en dicho principio. Se busca mostrar que la concepción de bien que Rawls presenta allí padece de “insuficiencia moral” y se defiende la tesis de que su aproximación a la idea de bien (...) opaca la dimensión práctica de la racionalidad.

El presente estudio tiene como objetivo describir el diálogo que la narrativa hispanoamericana de vanguardia sostuvo con la figura del accidente durante el siglo XX, a partir de un esquema de análisis que examina la asimilación de este fenómeno sociocultural en el plano del contenido, de la forma y de la recepción literarias. Para ello, establecemos un modelo de lectura basándose en las observaciones planteadas por Macedonio Fernández en su Museo de la Novela de la Eterna , y analizamos desde (...) este marco de referencia la figuración estético-política del accidente en una muestra ilustrativa de relatos. This article describes the dialogue between Latin American vanguard narrative and the figure of the accident during the twentieth century. We propose a model of analysis that examines the assimilation of this socio-cultural phenomenon in terms of literary structure, reception and content. We propose a reading model based on the insightful contributions of Macedonio Fernandez's Museo de la Novela de la Eterna, and analyze the political-aesthetical figuration of the accident in a corpus of exemplary texts.

Las ruinas y las sombras de Manderley aborda posibles relaciones interpretativas recíprocas entre la novela de Daphne du Maurier Rebecca y la película homónima de Alfred Hitchcock. Algunos de los aspectos que se consideran relevantes en este estudio son: el tratamiento de las “ruinas de la memoria” derridianas dentro de la novela y del propio Hitchcock, la diferenciación y el enfrentamiento de la protagonista “externa” con el mundo de los “internos” de Manderley, los valores icónicos y simbólicos del texto literario (...) y de la visualización fílmica, y las posiciones éticas que implican la elección o el rechazo de ciertos recursos narrativos en ambas obras.

The debate between the pure or fundamentalist branch of mathematics and the applied one induces to discuss dispassionately the links between the queen of sciences and the development of technology. To avoid the existing difficulty in separating the concrete daily problems from the conceptual and theoretic reflections, it generally produces good results to show some elements of the relations between mathematics and teehnology. The autonomous position, which characterizes the mathematics of absolute freedom, clashes with the quick development of technology, which (...) creates a new structure of mathematics. This development produces a pennanent interrogation about what is building and developing anyone who calls himself a mathematician. (shrink)

Con una clara intención analítica y reflexiva, intenta explicar las claves de la evolución de nuestro sistema sanitario, en donde se conjugan factores acaecidos fuera de nuestras fronteras, hasta nuestra propia maduración con la consiguiente afloración de exigencias que propician un desarrollo espectacular que va homologándose con otros países de nuestro entorno y que tienen su punto de arranque cuando nuestra Constitución reconoce el derecho a la salud de todos los ciudadanos.

En el presente trabajo se analizan tres piezas de Rodolfo Usigli bajo la perspectiva del chantaje que impulsa la confrontación de dos fuerzas axiológicas que son la verdad y la mentira; sin embargo, no se trata sólo de dos antagonismos que determinan la temática de su teatro, sino además son dos términos cuya confrontación construye la estructura de la mayor parte de sus dramas. Esta confrontación entre verdad y mentira Rodolfo Usigli la maneja desde distintas aristas, como es la desinformación, (...) la obediencia a la autoridad y la gubernamentalidad. (shrink)

Reflections on Peirce’s theory of abduction have not been free of controversy, given the difficulty to determine clearly the nature and epistemic function of this inference. The article examines three ways of understanding the concept of abduction, developed by Peirce himself throughout his work. The main objective is to reconstruct the logical, methodological, and instinctive conception of this type of reasoning in order to establish the possibility of a theory of abduction.

RESUMEN El suicidio o el interfictium spinoziano es a simple vista una categoría marginal en el pensamiento de Spinoza. La vasta producción filosófica en torno a quien ha sido considerado como el filósofo de la "anomalía salvaje" o al mismo tiempo el pensador de los "afectos alegres" ignora, o en el mejor de los casos trata oblicuamente, las nociones de muerte y suicidio. La paradoja es total porque el rechazo hacia el pensamiento de la muerte contrasta con la profusa interpelación (...) a dicha categoría en su Ética. El propósito de este artículo es mostrar que la expresión negativa del suicidio, como pura imposibilidad y servidumbre respecto a causas externas es, sin embargo, menos literal y clara, cuando en su análisis se incorporan aquellos elementos centrales de su obra más emblemática. Libertad, Necesidad y Sustancia, entre otros, son conceptos que, desde el suicidio se tensionan mostrando los propios límites del orden geométrico esbozado por Spinoza. ABSTRACT Suicide or spinozian interfictium is at first sight a marginal category in Spinoza's thought. The vast philosophical production on who has been considered the philosopher of the "savage anomaly" or at the same time the "cheerful affects" thinker, ignores or, in the best-case scenario, obliquely addresses the notions of death and suicide. The paradox is complete because the rejection towards the thought of death contrasts with the profuse questioning of the aforesaid category in its Ethics. The goal of this article is to show that the negative expression of suicide, as pure impossibility and servitude with respect to external causes is however, less literal and clear when some central elements of its most emblematic work are incorporated in its analysis. Liberty, Need, and Substance, among others, are concepts that from suicide get tensioned showing the own limits of the geometric order insinuated by Spinoza. (shrink)

This 1995 volume views important social and political issues through the eyes of economists. Pioneered by Gary Becker, this approach asserts that all actions, whether working, playing, dating, or mating, have economic motivations and consequences, and can be analysed using economic reasoning. Intended as an introduction to the current state of the field, the essays are informal and non-technical, while still using up-to-date economic reasoning to illuminate such topics as crime, marriage, discrimination, immigration, fads and fashions. The expanding domain of (...) economics is illustrated, as problems from sociology, political science, anthropology, and public policy are all included in this Beckerian view: the world of human interaction, as seen by an economist.

En Teoría de la justicia Rawls no prestó suficiente atención a cómo sus principios podrían realizarse al interior de un régimen socioeconómico específico, por lo que entre sus críticos ha habido desacuerdo sobre cuál de dichos regímenes resulta más adecuado para llevar a cabo su concepción de la justicia. Con la finalidad de contribuir a esta discusión, en este artículo examino los argumentos que Rawls presentó a favor del socialismo liberal y de la democracia de propietarios como los sistemas sociales (...) más adecuados para realizar su teoría. La discusión anterior me permitirá mostrar las críticas que Rawls presentó a las formas tradiciones del estado del bienestar. (shrink)

Las reflexiones en torno al concepto de abducción de Peirce no han estado exentas de controversias, debido a la dificultad para determinar con claridad la naturaleza y la función epistémica de esta inferencia.

El concepto de capital social se encuentra ampliamente difundido en Latinoamérica –a escala local, nacional y supra-nacional- como fundamento y recomendación en la aplicación de políticas sociales destinadas a la disminución de la pobreza, entre las que se encuentran los programas y emprendimientos de vivienda social. La intención del presente artículo es señalar los límites que la disparidad de definiciones y el uso ambiguo de este término impone a su capacidad interpretativa y explicativa en relación con los complejos procesos sociales (...) en que se inscribe. Se intentará ejemplificar esta cuestión a partir de la interpretación y análisis de dos experiencias relevantes en la producción de hábitat popular que se encuentran en curso en la ciudad de Buenos Aires. De las mismas se desprenden que la capacidad de movilización y disponibilidad del recurso vinculado al capital social implica necesariamente una apuesta de luchas en donde lo político juega un rol relevante.

Early in animal development, gradients of secreted morphogenic molecules, such as Sonic hedgehog (Shh), Wnt and TGFβ/Bmp family members, regulate cell proliferation and determine the fate and phenotype of the target cells by activating well‐characterized signalling pathways, which ultimately control gene transcription. Shh, Wnt and TGFβ/Bmp signalling also play an important and evolutionary conserved role in neural circuit assembly. They regulate neuronal polarization, axon and dendrite development and synaptogenesis, processes that require rapid and local changes in cytoskeletal organization and plasma (...) membrane components. A key question then is whether morphogen signalling at the growth cone uses similar mechanisms and intracellular pathway components to those described for morphogen‐mediated cell specification. This review discusses recent advances towards the understanding of this problem, showing how Shh, Wnt and TGFβ/Bmp have adapted their ‘classical’ signalling pathways or adopted alternative and novel molecular mechanisms to influence different aspects of neuronal circuit formation.

Este trabajo tiene por objetivo analizar Hch 16 en tanto relato organizado por el autor en base a las tensiones de las ἐκκλησίαι de inicios del siglo II. Identificaremos en la narración cómo se representan las inquietudes por el liderazgo comunitario y la forja de una identidad grupal. En el primer caso, la interacción de Pablo con los οἶκοι filipenses propicia una reflexión acerca de la relación entre ministros y fieles. En el segundo, las diferentes designaciones que recibe Pablo en (...) el capítulo evidenciarían no solo la compleja identidad de los creyentes, sino la propuesta comunitaria del autor. (shrink)

The Central Dogma of molecular biology, which holds that DNA makes protein and not the other way around, is as influential as it is controversial. Some believe the Dogma has outlived its usefulness, either because it fails to fully capture the ins-and-outs of protein synthesis (Griffiths and Stotz, 2013; Stotz, 2006), because it turns on a confused notion of information (Sarkar, 2004), or because it problematically assumes the unidirectional flow of information from DNA to protein (Gottlieb, 2001). This paper evaluates (...) an underexplored defense of the Dogma, which relies on the assumption that the Dogma and the Inheritance of Acquired Traits, a principle which dates as far back as Jean Baptiste-Lamarck, are incompatible principles (Smith, 1993; Judson, 1979; Dawkins, 1970; Cobb, 2017; Wilkins, 2002; Graur, 2018). By appealing to empirical evidence in molecular science, I argue that this apparent incompatibility is indeed merely apparent. I conclude by briefly demonstrating how these considerations bear on the topic of conceptual pluralism in the philosophy of science (Stencel and Proszewska, 2018; Lu and Bourrat, 2018). (shrink)

Roughly, the Central Dogma of molecular biology states that DNA codes for protein, not the other way around. This principle, which is still heralded as an important element of contemporary biological theory, has received much critical attention since its original formulation by Francis Crick in 1958. Some have argued that the principle should be rejected, on the grounds that it fails to fully capture the ins-and-outs of protein synthesis, while others have argued that the Dogma is predicated on notions of (...) information that are simply implausible. Yet, despite all this criticism, there is much about the Dogma that has not been said. Existing discussions, for example, gloss over the many distinct, logically independent readings of the Central Dogma that have been defended in the philosophical and biological literature, making it difficult to see which dogma is being criticized. Additionally, this oversight makes it unclear what the overall upshot of these discussions should be taken to be. My aim in this paper is to fix this. (shrink)
