The aim of this article is to think the relationship between the search for reality or the truth with methodology, by asking some questions to different theoretical perspectives and by analyzing different answers given by the authors and theories. From the sociological theoretical perspective, it deals with two levels of thought with methodological implications. The first refers to the methodological implications arising from the search for reality or truth. The second, epistemological, refers to the theoretical and paradigmatic duality between subjective (...) capacity decisions against the constriction of the subjects by the structures. El objetivo de este artículo es pensar el nexo de la búsqueda de la realidad o de la verdad con la metodología, al plantear preguntas a diversas corrientes teóricas y analizar las respuestas de cada autor o corriente al respecto. Desde la perspectiva teórica sociológica, se abordan dos niveles de reflexión con implicaciones metodológicas. El primero, hace referencia a las implicaciones metodológicas derivadas de la búsqueda de la realidad o de la verdad. El segundo, de carácter epistemológico, hace referencia a la dualidad teórica y paradigmática existente entre la capacidad subjetiva de decisión frente a la constricción de los sujetos por parte de las estructuras.

We present a theoretical discussion of the sociological contribution concerning decisions in organizations. Two theories stand. The first, based on the decision process from a critical theory of the traditional linear multi rational by Lucien Sfez, argues that the decision is a process of interactions and treats it as an institutional process based on the freedom of the subject. The second theory based on self-referential systems by Niklas Luhmann, interprets organizations as systems-making, and understands the concept of decision as purely (...) epistemological specificity, abstracted from the decision of all the elements and organizational variables associated with it. Se expone un debate teórico sobre la aportación sociológica referente a las decisiones en las organizaciones. Sobresalen dos teorías de las decisiones. La primera, basada en el proceso de decisión a partir una teoría crítica de la multirracionalidad lineal elaborado por Lucien Sfez, al plantear que con la decisión se trata de un proceso de interacciones, al ser considerada como un proceso institucional fundamentado en la libertad del sujeto. La segunda fundamentada en la teoría de sistemas autorreferenciales, interpreta las organizaciones como sistemas de decisiones y entiende el concepto de decisión en su especificidad puramente epistemológica, al abstraer de la decisión de todos los elementos y variables organizacionales relacionados con ella (Niklas Luhmann).

The rapid dynamics of COVID-19 calls for quick and effective tracking of virus transmission chains and early detection of outbreaks, especially in the “phase 2” of the pandemic, when lockdown and other restriction measures are progressively withdrawn, in order to avoid or minimize contagion resurgence. For this purpose, contact-tracing apps are being proposed for large scale adoption by many countries. A centralized approach, where data sensed by the app are all sent to a nation-wide server, raises concerns about citizens’ privacy (...) and needlessly strong digital surveillance, thus alerting us to the need to minimize personal data collection and avoiding location tracking. We advocate the conceptual advantage of a decentralized approach, where both contact and location data are collected exclusively in individual citizens’ “personal data stores”, to be shared separately and selectively, voluntarily, only when the citizen has tested positive for COVID-19, and with a privacy preserving level of granularity. This approach better protects the personal sphere of citizens and affords multiple benefits: it allows for detailed information gathering for infected people in a privacy-preserving fashion; and, in turn this enables both contact tracing, and, the early detection of outbreak hotspots on more finely-granulated geographic scale. The decentralized approach is also scalable to large populations, in that only the data of positive patients need be handled at a central level. Our recommendation is two-fold. First to extend existing decentralized architectures with a light touch, in order to manage the collection of location data locally on the device, and allow the user to share spatio-temporal aggregates—if and when they want and for specific aims—with health authorities, for instance. Second, we favour a longer-term pursuit of realizing a Personal Data Store vision, giving users the opportunity to contribute to collective good in the measure they want, enhancing self-awareness, and cultivating collective efforts for rebuilding society.

Regularization may be used as an alternative to dimensionality reduction when the number of variables in a model is much larger than the number of available observations. In a recent study from our group regularized regression was employed to quantify brain functional connectivity in a sample of healthy controls using a brain parcellation and resting state fMRI images. Here regularization is applied to evaluate resting state connectivity abnormalities at the voxel level in a sample of patients with schizophrenia. Specifically, ridge (...) regression is implemented with different degrees of regularization. Results are compared to those delivered by the weighted global brain connectivity method, which is based on averaged bivariate correlations and from the non-redundant connectivity method, a dimensionality reduction approach that applies supervised principal component regressions. Ridge regression is able to detect a larger set of abnormally connected regions than both GBC and NRC methods, including schizophrenia related connectivity reductions in fronto-medial, somatosensory and occipital structures. Due to its multivariate nature, the proposed method is much more sensitive to group abnormalities than the GBC, but it also outperforms the NRC, which is multivariate too. Voxel based regularized regression is a simple and sensitive alternative for quantifying brain functional connectivity. (shrink)

This paper presents a human-robot closely collaborative solution to cooperatively perform surface treatment tasks such as polishing, grinding, finishing, deburring, etc. The proposed scheme is based on task priority and non-conventional sliding mode control. Furthermore, the proposal includes two force sensors attached to the manipulator end-effector and tool: one sensor is used to properly accomplish the surface treatment task, while the second one is used by the operator to guide the robot tool. The applicability and feasibility of the proposed collaborative (...) solution for robotic surface treatment are substantiated by experimental results using a redundant 7R manipulator: the Sawyer collaborative robot.

This volume analyzes in detail Spinoza's reasoning in Tractatus theologico-politicus, identifies allies and enemies in its historical context, and explores its more or less obvious connection with the Ethica.

El objetivo de este artículo es ofrecer una interpretación, en parte novedosa, del pasaje 5.54-5.5423 del Tractatus en el que Wittgenstein examina las proposiciones que representan relaciones intencionales como el juicio. La idea fundamental será que estas proposiciones se consideran como proposiciones que tratan de complejos y, en consecuencia, deberían analizarse de conformidad con el parágrafo 2.0201, lo que me llevará a desarrollar paso a paso el análisis propuesto. Adicionalmente, argumentaré que la teoría de Wittgenstein así entendida excluye la posibilidad (...) de juzgar sinsentidos, a diferencia de la teoría de Russell del juicio como relación múltiple.

In thirteen essays from different aesthetic traditions, Aesthetic Apprehensions: Silences and Absences in False Familiarities problematizes our habituated customs of seeing and reading the familiar to focus on that which cannot easily be comprehended but may be sensed through encounters with the ruptures and gaps that quietly beckon our attention.

En este artículo me propongo abordar el problema del tiempo en las sociedades contemporáneas desde un diálogo entre las construcciones teóricas de Moishe Postone y Hartmut Rosa y el trabajo de Michel Foucault. Los dos primeros se han centrado en explicar cómo la temporalidad se ha convertido en un tipo de dominación abstracta, impersonal y cuasiobjetiva a partir de conceptos como la densificación temporal, la aceleración o la hibridación. Foucault, en cambio, concibe el tiempo bajo el prisma de la racionalidad (...) política neoliberal, por la cual el tiempo pasa a ser un recurso que debe gestionarse por los sujetos en términos empresariales y que termina por configurar una ética neoliberal de la administración del tiempo. Este diálogo ejemplifica de manera privilegiada la tensión entre la coacción o la presión temporal y la administración estratégica del tiempo propia de las sociedades contemporáneas. (shrink)

"La solidarité que je ressentais avec les opprimés, avec ceux qui souffraient, a fait que je me suis spontanément`: tourné vers l'anarchisme - cette théorie qui traite des rapports de domination".

La science est un modèle qui mime dans l'abstrait le comportement de la nature. Créations du chercheur, les théories pour un fait donné peuvent être multiples et chacune valide. La science a des lois, la nature n'en a pas. L'ordre de la nature, c'est le chercheur qui l'y met. L'esprit, façonnant un amorphe premier, participe à la mise en forme de la nature produisant le Réel "en nous". Celle-ci, réciproquement, modèle l'esprit. De ce fait, l'univers n'existerait plus si l'homme disparaissait...

This book explores the notion of endangerment which stands at the heart of a network of concepts, values and practices dealing with objects considered threatened by extinction, and with the procedures aimed at preserving them. It looks at some of the fundamental ways in which this process involves science, but also more than science: not only data and knowledge and institutions, but also affects and values. With a focus on endangerment sensibility, it encapsulates tensions between the normative and the utilitarian, (...) the natural and the cultural. (shrink)

The development of Information and Communication Technologies has favored access to technological resources in adolescents. These tools provide access to information that can promote learning. However, they can also have a negative effect against people, as they can be used with other functionality, in which cyberbullying situations are caused during the interactions that arise when using social networks. The objective of this study was to determine the predictive value of the role of cyberbullying victims based on variables related to other (...) roles involved in cyberbullying and bullying, as well as personal characteristics, contextual characteristics and positive teamwork habits.. Information was collected from 227 students of the educational stages of Primary Education and Secondary Education, aged between 11 and 15 years, in a city with a high index of cultural diversity. The step-by-step technique was used to build the regression model. The results indicate that the model has a good goodness of fit coefficient. The role of cyberbully is the most important predictive variable of the role of the victim in cyberbullying and, to a lesser extent, the role of the witness in cyberbullying, the role of the witness in bullying, and the role of the victim of bullying. The role of the bullying aggressor and the variables sex, age, type of educational center, and teamwork habits are excluded in the predictive model. (shrink)
