Abduction according to Peirce: reflections from the south on the crisis of representation brought on by COVID-19

Paulina Aroch (2023, [Artículo, Artículo])

In this article, I reflect on the importance of abductive thinking for processes of material and conceptual reinvention in the context of the current public health crisis. Inseparable from the climate change engulfing the planet, this crisis provides the basis for a semiotic revolution. Therefore, I interrogate Peirce’s work without losing sight of my own time and place of interlocution. COVID-19 has brought with it a crisis of representation which, in contrast to that unleashed by the Holocaust and World War II, and to which the Frankfurt School responded, demands responses from the Global South. Beginning from Dussel’s call to defend life as a matter of ethical urgency in the face of its irresponsible objectification within colonial capitalist modernity –which arguably triggered the pandemic–, I trace a “nocturnal map” that registers the present meaning-making crisis, and allows for a reimagining and remaking of the world from elsewhere.

URBAN GREEN AND RESILIENCE: AN EXPLORATION IN CÓRDOBA, FORTÍN AND AMATLÁN, VERACRUZ, MEXICO

Rafael Arturo Muñoz-Marquez Trujillo Juan Valente Hidalgo Contreras (2022, [Artículo, Artículo])

This article shows the amount and location of Urban Green (VU) in Amatlán, Córdoba and Fortín, Veracruz, Mexico, in the context of urban resilience to global warming. The objectives of this work are: 1) to know the situation of this resource in terms of its availability (endowment) by present area; 2) measure the distances that separate the green from the population; and 3) determine the population served through the Public Urban Green (VUP) and Urban Green in general (VU-NDVI), as well as contrast with the endowment and distance recommendations of the Secretariat of Agrarian, Territorial and Urban Development (SEDATU).. The working hypotheses are: a) Fortn, Córdoba and Amatlán have a VUP allocation below that recommended by the WHO, but have the possibility of higher allocations, considering the VU-NDVI; and b) Fortín, Córdoba and Amatlán have a VUP system at a maximum distance of 400 meters from each block, and contain VU-NDVI areas at smaller distances. With census and cartographic data, satellite image processing, use of Geographic Information Systems, field verification of the data, and statistical analysis, the amount of VUP and VU-NDVI, the green area endowments per inhabitant, and the distances that separate the two types of green in the population. The results showed, on the one hand, that the allocation of VUP per inhabitant is below the WHO recommendations, but not the VU-NDVI and, on the other hand, that the VUP exceeds the maximum distance recommended by SEDATU, but not thus the VU-NDVI. Finally, it is pointed out that, although the majority of the population is served with VUP in accordance with SEDATU (although with very varied surfaces), the VU-NDVI serves 100% of it. The results show the potential of the latter to increase the share of green in cities such as those analyzed.

Debates contemporáneos sobre la eficacia de los derechos humanos en la globalización

ROBERTO MARTINEZ REGINO HECTOR ALEJANDRO RAMIREZ MEDINA (2023, [Libro])

En esta obra se abordan temáticas vinculadas a las demandas sociales que se han convertido en una fuente de interés y de preocupación para la academia y que, además, son el resultado del esfuerzo constante y persistente de posturas científicas que han permitido la apertura y el continuo desarrollo de líneas de investigación para la innovación del conocimiento susceptible de aplicación. Hoy en día, cualquier actividad humana a nivel individual o social, así como las actividades de la sociedad civil organizada o incluso de las instituciones del Estado están necesariamente vinculadas con los dos grandes ejes de la obra que tiene el lector en sus manos: los derechos humanos y la globalización.

En ese orden de ideas, no es de sorprendernos que las investigaciones académicas aquí presentadas sean visiones contemporáneas de cambios coyunturales y de propuestas de cambio a la estructura de las sociedades y que se interrogan sobre la vigencia del Contrato Social.

Detección de eventos violentos en publicaciones de redes sociales

Detection of violent events in social media publications

Esteban Ponce León (2023, [Tesis de maestría])

En los últimos años, ha habido un interés creciente en el monitoreo de redes sociales para recopilar información y, en algunos casos, para examinar la ocurrencia de delitos. Sin embargo, gran parte de las investigaciones hasta ahora solo se han centrado en ciudades de EE. UU. o extranjeras, y por ende, en publicaciones y conjuntos de datos en inglés El objetivo principal de esta tesis es diseñar un método que permita la identificación de publicaciones de eventos violentos en español y en Twitter, utilizando información multimodal y técnicas de aumento de datos que mejoren el rendimiento de los modelos. Para esto, el trabajo de investigación se dividió en dos fases experimentales. La primera orientada a identificar publicaciones a partir de solo texto, explorando diferentes técnicas de aumento de datos para texto y modelos de aprendizaje máquina y profundo. En la segunda fase, se extendió el método propuesto para abordar la identificación en un contexto multimodal, es decir, considerando tanto los textos de los tweets como las imágenes compartidas que los acompañan. En este caso el método propuesto consideró utilizar descripciones textuales de las imágenes y abordar la problemática desde el dominio textual, además se hicieron 2 tipos de aumento de datos para cada tipo de información. La evaluación de los métodos se hizo utilizando las colecciones de la tarea de evaluación DA-VINCIS 2022 y 2023. Los resultados demostraron una mejora en el rendimiento de los modelos al considerar el uso de información multimodal y el uso de aumento de datos.

In recent years, there has been a growing interest in monitoring social networks to gather information and, in some cases, to examine the occurrence of crime. However, much of the research so far has only focused on US or foreign cities, and thus on English-language publications and data sets. The main objective of this thesis is to design a method that allows the identification of publications of violent events in Spanish and on Twitter, using multimodal information and data augmentation techniques that improve the performance of the models. For this, the research work was divided into two experimental phases. The first aimed at identifying publications from only text, exploring different data augmentation techniques for text and machine and deep learning models. In the second phase, the proposed method was extended to address identification in a multimodal context, that is, considering both the texts of the tweets and the shared images that accompany them. In this case, the proposed method considered using textual descriptions of the images and addressing the problem from the textual domain, in addition, 2 types of data augmentation were made for each type of information. The evaluation of the methods was done using the collections of the DA-VINCIS 2022 and 2023 evaluation task. The results demonstrated an improvement in the performance of the models when considering the use of multimodal information and the use of data augmentation.

Variability of Microcirculation Detected by Blood Pulsation Imaging

Alexei Kamshilin (2013, [Artículo])

The non-invasive assessment of blood flow is invaluable for the diagnostic and monitoring treatment of numerous vascular and neurological diseases. We developed a non-invasive and non-contact method of blood pulsation imaging capable of visualizing and monitoring of the two-dimensional distribution of two key parameters of peripheral blood flow: the blood pulsation amplitude and blood pulsation phase. The method is based on the photoplethysmographic imaging in the reflection mode. In contrast with previous imaging systems we use new algorithm for data processing which allows two dimensional mapping of blood pulsations in large object's areas after every cardiac cycle. In our study we carried out the occlusion test of the arm and found (i) the extensive variability of 2D-distribution of blood pulsation amplitude from one cardiac cycle to another, and (ii) existence of the adjacent spots to which the blood is asynchronously supplied. These observations show that the method can be used for studying of the multicomponent regulation of peripheral blood circulation. The proposed technique is technologically simple and cost-effective, which makes it applicable for monitoring the peripheral microcirculation in clinical settings for example, in diagnostics or testing the efficiency of new medicines. © 2013 Kamshilin et al.
