Covid-19 and Digital Anti-Sinophobia in Argentina

While racial discrimination against people of Asian and particularly Chinese origin is well-understood in the Global North, its dynamics in the Global South remain under-investigated. Moreover, although Covid-19 contributed significantly to the reinforcement of sinophobic stereotypes around the globe, recent research has barely paid any attention to new forms of counter-reaction, such as those that evolve in digital channels, especially in Latin America. This paper sheds light on anti-Asian racism and the digitized counter-reactions of Chinese migrants before and after Covid-19 in the crucial case of Argentina. In the past, these migrants mostly remained silent when confronted with institutional racism. However, it was precisely the outbreak of Covid-19 that contributed to the creation of new forms of empowerment on online platforms by this racialized minority and that allowed them to present their demands to state agencies and to denounce sinophobic debates on social media. Methodologically, this study combines elements of process-tracing with both traditional and online ethnographic methods to explain these trickle-up effects.Fil: Baumann, Clara.

A produção jornalística e as mídias sociais : a utilização do facebook e do twitter na construção da notícia

Dissertação (mestrado)—Universidade de Brasília, Faculdade de Comunicação, Programa de Pós-Graduação em Comunicação, 2014.O presente trabalho está voltado à análise do jornalismo e suas possíveis mudanças estruturais (ou não) em tempos de internet e convergência digital. A proposta é estudar o jornalismo que se processa por meio da web. O enfoque é no processo de produção da notícia com o surgimento e a prática das mídias sociais – especificamente o Facebook e o Twitter. Interessa conhecer, sob a luz do newsmaking, o uso dessas mídias como ferramentas para os jornalistas e de que maneira elas participam na significação da realidade construída por esses profissionais. O objetivo, então, foi analisar se e em que medida essas mídias sociais influenciam na produção da notícia nos jornais Correio Braziliense e Jornal de Brasília, eleitos como o corpus deste trabalho. Partimos da suposição de que as rotinas jornalísticas clássicas são influenciadas pelo uso dessas mídias (especificamente Facebook e Twitter), para trabalhar a hipótese de que os jornalistas alteram suas rotinas de produção da notícia em função do uso das mídias sociais. ________________________________________________________________________________ ABSTRACTThe present work is focused on the analysis of journalism and its possible structural (or not) changes in times of internet and digital convergence. The proposal is to study journalism through the web. The focus is in the process of news production with the emergence and practice of social media - specifically Facebook and Twitter. We aim to understand, employing the theory of Newsmaking, the use of these media as tools for journalists and how these tools participate in the meaning of reality constructed by these professionals. The goal, then, was to examine whether and to what extent social media influence the production of news in the newspapers Correio Braziliense and Jornal de Brasília, elected as the corpus of this work. We start from the assumption that traditional journalistic routines are influenced by the use of these media (specifically Facebook and Twitter) to work with the hypothesis that journalists change their routines of news production due to the use of social media

diásporas chinas en España y Argentina: una tipología para analizar las relaciones diáspora-Estado en el caso chino

Centrándonos en Argentina y España, proponemos una tipología de los mecanismos que el Estado chino utiliza para interactuar con su diáspora. Aunque el covid-19 ha vuelto a poner en escena la diáspora china y su vinculación con los países de acogida, rara vez se ha analizado el rol del Estado de origen sobre su vida diaspórica. Teniendo en cuenta los casi 60 millones de chinos de ultramar y el creciente protagonismo de la RPC en el orden internacional, estas dinámicas resultan de gran relevancia. Basándonos en el concepto de “oro y gloria”, encontramos una fuerte interdependencia entre ambas instituciones: mientras el Estado chino moldea las acciones de sus comunidades overseas en sus diferentes realidades económicas, políticas, sociales y culturales, también se beneficia de sus acciones en el extranjero. Extraemos nuestros datos de las noticias sobre la diáspora china en España y Argentina a través de la técnica de web crawle

The LANDSUPPORT geospatial decision support system (S-DSS) vision: Operational tools to implement sustainability policies in land planning and management

Nowadays, there is contrasting evidence between the ongoing continuing and widespread environmental degradation and the many means to implement environmental sustainability actions starting from good policies (e.g. EU New Green Deal, CAP), powerful technologies (e.g. new satellites, drones, IoT sensors), large databases and large stakeholder engagement (e.g. EIP-AGRI, living labs). Here, we argue that to tackle the above contrasting issues dealing with land degradation, it is very much required to develop and use friendly and freely available web-based operational tools to support both the implementation of environmental and agriculture policies and enable to take positive environmental sustainability actions by all stakeholders. Our solution is the S-DSS LANDSUPPORT platform, consisting of a free web-based smart Geospatial CyberInfrastructure containing 15 macro-tools (and more than 100 elementary tools), co-designed with different types of stakeholders and their different needs, dealing with sustainability in agriculture, forestry and spatial planning. LANDSUPPORT condenses many features into one system, the main ones of which were (i) Web-GIS facilities, connection with (ii) satellite data, (iii) Earth Critical Zone data and (iv) climate datasets including climate change and weather forecast data, (v) data cube technology enabling us to read/write when dealing with very large datasets (e.g. daily climatic data obtained in real time for any region in Europe), (vi) a large set of static and dynamic modelling engines (e.g. crop growth, water balance, rural integrity, etc.) allowing uncertainty analysis and what if modelling and (vii) HPC (both CPU and GPU) to run simulation modelling 'on-the-fly' in real time. Two case studies (a third case is reported in the Supplementary materials), with their results and stats, covering different regions and spatial extents and using three distinct operational tools all connected to lower land degradation processes (Crop growth, Machine Learning Forest Simulator and GeOC), are featured in this paper to highlight the platform's functioning. Landsupport is used by a large community of stakeholders and will remain operational, open and free long after the project ends. This position is rooted in the evidence showing that we need to leave these tools as open as possible and engage as much as possible with a large community of users to protect soils and land

Comparison of the antioxidant potential of antiparkinsonian drugs in different in vitro models

Parkinson's disease (PD) is characterized by progressive degeneration of dopaminergic neurons in the substantia nigra pars compacta. Furthermore, oxidative stress plays a role in PD, causing or contributing to the neurodegenerative process. Currently PD has only symptomatic treatment and still nothing can be done to stop the degenerative process of the disease. This study aimed to comparatively evaluate the antioxidant capacity of pramipexole, selegeline and amantadine in different in vitrostudies and to offer possible explanations on the molecular antioxidant mechanisms of these drugs. In vitro, the antioxidant capacity of the drugs was assessed by the ability of antiparkinsonian drugs to decrease or scavenge ROS in the neutrophil respiratory burst, ability of antiparkinsonian drugs to donate hydrogen and stabilize the free radical 2,2-diphenyl-1-picryl-hydrazyl (DPPH•), to scavenge 2,2'-azino-di-(3-ethylbenzthiazoline-6-sulphonic acid (ABTS+) and evaluation of the ferric reducing antioxidant power (FRAP). This study demonstrated that both pramipexole and selegiline, but not amantadine, have antioxidant effects in vitro by scavenging superoxide anion on the respiratory burst, donating electron in the ABTS+ assay and presenting ferric reduction antioxidant power. This chemical structure-related antioxidant capacity suggests a possible neuroprotective mechanism of these drugs beyond their already recognized mechanism of action

Brazilian Consensus on Photoprotection

Brazil is a country of continental dimensions with a large heterogeneity of climates and massive mixing of the population. Almost the entire national territory is located between the Equator and the Tropic of Capricorn, and the Earth axial tilt to the south certainly makes Brazil one of the countries of the world with greater extent of land in proximity to the sun. The Brazilian coastline, where most of its population lives, is more than 8,500 km long. Due to geographic characteristics and cultural trends, Brazilians are among the peoples with the highest annual exposure to the sun. Epidemiological data show a continuing increase in the incidence of nonmelanoma and melanoma skin cancers. Photoprotection can be understood as a set of measures aimed at reducing sun exposure and at preventing the development of acute and chronic actinic damage. Due to the peculiarities of Brazilian territory and culture, it would not be advisable to replicate the concepts of photoprotection from other developed countries, places with completely different climates and populations. Thus the Brazilian Society of Dermatology has developed the Brazilian Consensus on Photoprotection, the first official document on photoprotection developed in Brazil for Brazilians, with recommendations on matters involving photoprotection

Aplicación de actividades para practicar habilidades de pensamiento crítico y superior en un curso universitario básico de electromagnetismo: algunos resultados

This work shows the results obtained in the implementation of actions ("checkings" and partial evaluation) which have been thought and elaborated by the teachers with the proposal of promoting in the students the possibility of developing a higher and critical thinking. The methodology used is a generic case study in which the sample is formed by all the assistant students to the Physics III course, of the Bachelor in Physics and Teaching Training in Physics, during the year 2007 in the Faculty of Exact and Natural Science of the National University of La Pampa, Argentine. It may be concluded that, the proposed actions to facilitate higher and critical thinking have promoted in this group of students a critical and reflexive learning, allowing them to integrate knowledge, to evaluate themselves and to be evaluated during the developing of the contends of "Electrostatic and magnetostatic fields related with their sources".En este trabajo se hace referencia a los resultados obtenidos de la aplicación de las acciones ("chequeos" y evaluación parcial) pensadas y elaboradas por los docentes, tendientes a favorecer en los estudiantes la posibilidad de desarrollar destrezas intelectuales del pensamiento superior y crítico. La metodología utilizada es un estudio de caso genérico en el que la muestra está constituida por la totalidad de los alumnos que cursaron la asignatura Física III en el año 2007 de las carreras Licenciatura en Física y Profesorado en Física de la Facultad de Ciencias Exactas y Naturales de la Universidad Nacional de La Pampa, Argentina. Se puede concluir que, las acciones propuestas como facilitadoras del pensamiento crítico y superior han promovido, en este grupo de alumnos un aprendizaje críticamente reflexivo y permitieron a los mismos integrar el conocimiento, autoevaluarse y ser evaluados durante el desarrollo del tema "Campos eléctricos y magnéticos relacionados con sus fuentes"

Habilidades de pensamiento crítico y superior desarrolladas por un grupo de alumnos de carreras de Física universitaria: Resultados de entrevistas realizadas a sus docentes

This work shows the results obtained from the analysis of in-depth interviews carried on a group of students´ teachers of the Bachelor in Physics and Teaching Training in Physics, in the Faculty of Exact and Natural Science of the National University of La Pampa, Argentine. The methodology used is a generic case study in which the focus is set in teachers´ opinions about scientific thinking changes produced in students to which, an integrated teaching strategy, based in the practice of higher and critical thinking, was applied in a basic electromagnetism course. It is concluded that, in these students those skills have been promoted, in all the cognitive dominions as they show this capacity in all the courses after that in which the strategy was applied.En este trabajo se muestran los resultados obtenidos del análisis de entrevistas en profundidad efectuadas a docentes de un grupo de alumnos, de las carreras Licenciatura en Física y Profesorado en Física de la Facultad de Ciencias Exactas y Naturales de la Universidad Nacional de La Pampa, Argentina. La metodología empleada es un estudio de casos genérico en el cual el foco está puesto en las opiniones de los docentes acerca de los cambios en la forma de pensamiento científico del grupo de estudiantes al cual se aplicó, en un curso básico de electromagnetismo una estrategia de enseñanza integradora, basada en la práctica de habilidades de pensamiento crítico y superior. Se concluye que se ha promovido en estos estudiantes el desarrollo de dichas habilidades, en todos los niveles del dominio cognitivo, al poner ellos de manifiesto esta capacidad durante el cursado de la de totalidad de las asignaturas, posteriores a aquella donde se aplicó la estrategia
