Trust in vaccination is eroding, and attitudes about vaccination have become more polarized. This is an observational study of Twitter analyzing the impact that COVID-19 had on vaccine discourse. We identify the actors, the language they use, how their language changed, and what can explain this change. First, we find that authors cluster into several large, interpretable groups, and that the discourse was greatly affected by American partisan politics. Over the course of our study, both Republicans and Democrats entered the (...) vaccine conversation in large numbers, forming coalitions with Antivaxxers and public health organizations, respectively. After the pandemic was officially declared, the interactions between these groups increased. Second, we show that the moral and non-moral language used by the various communities converged in interesting and informative ways. Finally, vector autoregression analysis indicates that differential responses to public health measures are likely part of what drove this convergence. Taken together, our results suggest that polarization around vaccination discourse in the context of COVID-19 was ultimately driven by a trust-first dynamic of political engagement. (shrink)

El objetivo de este artículo es analizar la relación entre tiempo y memoria en dos escritos de Aristóteles: en la Física IV y en Acerca de la memoria y de la reminiscencia. En Física IV Aristóteles define el tiempo, en relación con el cambio y movimiento del mundo sublunar, como número del movimiento y del cambio. Por otra parte, en Acerca de la memoria y la reminiscencia realiza un análisis fenomenológico del tiempo que no requiere una concepción numérica, sino un (...) reconocimiento de que lo que se hace presente, como imagen, forma parte de una experiencia pasada, caracterizada por no ser. De esta manera, la interpretación numérica del tiempo es el método de recuperación precisa de la memoria, pero el recuerdo implica una experiencia del tiempo, a partir de la cual se constituye la memoria como negatividad.

Epidemiological models directly shape policy responses to public health crises. We argue that they also play a less obvious but important role in solving certain coordination problems and social dilemmas that arise during pandemics. This role is both ethically and epistemically valuable. However, it also gives rise to an underappreciated dilemma, as the features that make models good at solving coordination problems are often at odds with the features that make for a good scientific model. We examine and develop this (...) dilemma in the context of the COVID-19 pandemic, and suggest extensions to other domains. (shrink)

Protests and counter-protests seek to draw and direct attention and concern with confronting images and slogans. In recent years, as protests and counter-protests have partially migrated to the digital space, such images and slogans have also gone online. Two main ways in which these images and slogans are translated to the online space is through the use of emoji and hashtags. Despite sustained academic interest in online protests, hashtag activism and the use of emoji across social media platforms, little is (...) known about the specific functional role that emoji and hashtags play in online social movements. In an effort to fill this gap, the current paper studies both hashtags and emoji in the context of the Twitter discourse around the Black Lives Matter movement. (shrink)

The question of how the probabilistic opinions of different individuals should be aggregated to form a group opinion is controversial. But one assumption seems to be pretty much common ground: for a group of Bayesians, the representation of group opinion should itself be a unique probability distribution, 410–414, [45]; Bordley Management Science, 28, 1137–1148, [5]; Genest et al. The Annals of Statistics, 487–501, [21]; Genest and Zidek Statistical Science, 114–135, [23]; Mongin Journal of Economic Theory, 66, 313–351, [46]; Clemen and (...) Winkler Risk Analysis, 19, 187–203, [7]; Dietrich and List [14]; Herzberg Theory and Decision, 1–19, [28]). We argue that this assumption is not always in order. We show how to extend the canonical mathematical framework for pooling to cover pooling with imprecise probabilities by employing set-valued pooling functions and generalizing common pooling axioms accordingly. As a proof of concept, we then show that one IP construction satisfies a number of central pooling axioms that are not jointly satisfied by any of the standard pooling recipes on pain of triviality. Following Levi, 3–11, [39]), we also argue that IP models admit of a much better philosophical motivation as a model of rational consensus. (shrink)

In the present article we approach different critical interpretations of the figure and the work of the intellectual. We start with Lyotard’s analysis of the decline of universalist parameters and the consequent disappearance of the figure of the classical intellectual. Next, we analyze the description of this figure made by Foucault and Blanchot, of which they defend its validity. These two authors explore the labour of the intellectual from a different perspective than the prescriptive, universalist and liberating discourses that characterized (...) it for a certain time. Proposing in this way a remarkable shift in the way of understanding the intellectual commitment, both bet on the affirmation of some practices without any programmatic theoretical anticipation, which will demand an exposure and alteration of the subject, where knowledge will no longer be safeguard, foundation or orientation.

The objectives of the present study were to adapt a grief intervention program to family caregivers of patients with dementia, and assess its effectiveness in improving the symptoms of grief and other health-related variables. The intervention was based on Shear and Bloom's grief intervention program, with the necessary adaptations for use in the grieving process for a family member's illness. A total of 52 family caregivers of individuals with dementia participated. They were evaluated using a battery of self-report measures assessing (...) grief, overload, resilience, post-traumatic growth, experiential avoidance, health-related quality of life, and benefits of care. The results suggest that the program is effective in improving grief symptoms, caregiver burden, resilience, post-traumatic growth, and quality of life of family caregivers. It is necessary to create and implement interventions targeting caregivers' feelings and manifestations of ambiguous grief, because there is a lack of programs providing an efficient solution for the mental and physical health of caregivers, and because of the human and socioeconomic cost involved in neglecting this group.

According to the broaden-and-build theory of positive emotions, the frequency of positive emotions is associated with the development of positive attitudes, cognitions, and behaviors in organizational contexts. However, positive and negative attitudes at work might also be influenced by different personal and job resources. While emotional intelligence has been significantly associated with positive job attitudes and personal well-being, no studies have yet examined the joint role of teacher happiness and emotional intelligence in key teacher job attitudes. The present study assesses (...) whether emotional intelligence interacts with levels of teacher happiness to jointly explain important teacher job attitudes. A total sample of 685 teaching professionals filled out a battery of scales including subjective happiness, emotional intelligence, job satisfaction, and turnover intention. Our results revealed that subjective happiness was significantly associated with both higher job satisfaction and lower turnover intention. Likewise, emotional intelligence was positively related to happiness and job satisfaction, and negatively related to turnover intention. Finally, interaction analysis showed the main effects of happiness and emotional intelligence in explaining teacher job attitudes. Beyond the main effects, the interaction effects of happiness and emotional intelligence were significant in predicting all teachers' job attitude indicators, even controlling for the effects of their sociodemographic variables. This work expands our knowledge about the role of teachers' positive emotions in the development of positive work attitudes, and also supports the inclusion of emotional skills in future teacher preparation programs as resources to facilitate work-related well-being.

Mucho se ha escrito sobre la imposibilidad de representar el Holocausto como quiebra en el proceso civilizador. Sin embargo, la convocatoria al silencio pronto fue rota por una controversia de relatos que difieren en sí sustancialmente. Desde entonces, el debate sobre la pertinencia de narraciones de corte realista, melodramática o cómica, cuando no fantástica, su legitimidad o ilegitimidad y el uso de material de archivo en los filmes sigue generando importantes dudas a la hora de abarcar la representatividad del horror. (...) Precisamente, al ser una cuestión de extremada sensibilidad para la historia en general y la europea en particular, el Holocausto no deja de interpelarnos con nuevos y antiguos interrogantes. Preguntas que se agudizan más si cabe a la hora de seleccionar fragmentos o filmes para trabajarlos desde el aula.. (shrink)

Rationale, aims and objectives Given the increasing prevalence of cataract and demand for cataract extraction surgery, patients must often wait to undergo this procedure. We validated a previously developed priority scoring system in terms of clinical variables, pre-intervention health status, appropriateness of surgery and gain in visual acuity (VA) and health-related quality of life (HRQoL).Methods Explicit prioritization criteria for cataract extraction created by a variation of the Research and Development (RAND) and University of California Los Angeles appropriateness methodology were retrospectively (...) applied to a prospective cohort of 5257 patients on waiting lists to undergo cataract by phacoemulsification at 17 hospitals in Spain. Demographic data, clinical data and data related to surgical technique were collected by trained ophthalmologists. Patients were evaluated by their ophthalmologist before the intervention and 6 weeks afterward. They also completed, by mail, the Visual Function Index (VF-14) before the intervention and 3 months afterward.Results High-priority patients experienced greater improvement in VA and HRQoL than those classified as intermediate or low-priority (P < 0.0001), even after adjusting by VA and the VF-14 score at baseline. The time to intervention was the same for high-priority patients as it was for intermediate and low-priority patients.Conclusions The priority score we developed identified patients most likely to experience the greatest improvements from cataract extraction. Use of this tool could provide a fairer and more rational way to prioritize patients for cataract extraction. (shrink)

We explore which types of probabilistic updating commute with convex IP pooling. Positive results are stated for Bayesian conditionalization, imaging, and a certain parameterization of Jeffrey conditioning. This last observation is obtained with the help of a slight generalization of a characterization of externally Bayesian pooling operators due to Wagner :336–345, 2009). These results strengthen the case that pooling should go by imprecise probabilities since no precise pooling method is as versatile.

Los centros educativos pueden convertirse en entornos positivos implementando programas basados en evidencias. El objetivo de este artículo es presentar el programa “Creciendo Juntos” y analizar su eficacia en la promoción del establecimiento de relaciones positivas en estos. Se contó con una muestra de 990 alumnos (=12.96; 47.5% chicas) que respondieron la Escala sobre la percepción del alumnado acerca de sus relaciones en el centro y su nivel de participación educativa (RMSEA=.049; 90%.043-.055; CFI=.976; TLI =.967 y SRMR=.026). Mientras el grupo (...) de control empeora en sus relaciones y su participación en el centro, el grupo de intervención se mantiene. (shrink)

Jacques Derrida afirma que el perdón está envuelto en una aporía según la cual solo se puede perdonar lo que es imperdonable. Perdonar lo perdonable sería tan solo un modo de excusar o de saldar una deuda. Si entonces únicamente hay perdón de lo imperdonable, el perdón debe hacer lo imposible y atravesar su propia imposibilidad. Esta manera de aproximarse al perdón cuestiona la lógica de las condiciones que determinan cuándo algo es perdonable, pero también toda certeza en cuanto a (...) su tener lugar, a la posibilidad de su teorización, objetivación o presentación. En este artículo expondré algunos de los aspectos en los que Derrida se separa tanto de Hannah Arendt como de Vladimir Jankélévitch en torno al límite entre el perdón y lo imperdonable. A partir de esto abordaré el «si lo hay» que acompaña al perdón derridiano, no tanto como una duda sobre su existencia, sino como la marca de un «indecidible», una instancia secreta, irreductible e inapropiable a toda forma de determinación. Se llega así a plantear que Derrida no aspira a elaborar una teoría sobre el perdón y sus posibilidades, sino que más bien lo inscribe en una reflexión sobre la justicia, heterogénea al derecho o a la ley, pero no obstante indisociable de sus formas. Este desajuste abre un amplio campo de interrogación sobre lo que pueda implicar tornar posible la imposibilidad del perdón. (shrink)

Interessa ao educador científico contemporâneo compreender as relações entre ciência e religião, particularmente investigando como elas se dão entre seus estudantes e na realidade por eles vivenciada, posto que essa bagagem cultural está presente na sala de aula. Neste sentido, o presente trabalho objetiva identificar e analisar as principais características e tendências de investigações sobre as relações entre ensino de ciências e a religião, a fim de fornecer subsídios atualizados para quem o desejar ou necessitar. Para tanto, uma revisão de (...) referenciais teóricos sobre a relação ciência-religião é apresentada e, em sequência, reúnem-se e analisam-se produções científicas publicadas entre 2004 e 2020 com foco nas relações entre ensino de ciências e a religião. Entre os resultados observados destaca-se que as relações entre religião e ciência não são homogêneas dentro da escola (nem fora dela): diferentes estudantes, bem como diferentes professores, têm diferentes opiniões, atitudes, e visões de mundo sobre o tema. Além disso, os pesquisadores sugerem atuações pedagógicas frente às relações entre religião e ciência: os conhecimentos sobre a história da ciência bem como conhecimentos sobre a história das relações entre a ciência e a religião são relatados como ferramentas importantes e há unanimidade quanto à importância de combater a noção de conflito entre ciência e religião.

Este ensaio acadêmico sobre a infância de terreiro está redigido segundo uma leitura de mundo do candomblé. Há muitas leituras de mundo. Nossas experiências de vida colocaram-nos diante de, pelo menos duas delas: a leitura religiosa como a do candomblé e a leitura laica da pedagogia. No desenrolar dessas experiências observamos no cotidiano de nossas salas de aula - nos cursos de formação de professores e no cotidiano da Educação Infantil - um grande desconhecimento sobre a população de terreiro, em (...) especial sobre suas crianças. O texto aborda o conceito de infância afrodescendente, com base em pesquisas realizadas nos últimos dez anos pelo Grupo de Estudos e Pesquisa Educação, Diversidade e Religião em comunidades religiosas tradicionais situadas no estado do Rio de Janeiro e no estado da Bahia, cujo objetivo é identificar, levar em consideração, compreender de forma pluridisciplinar formas de apropriação, expropriação do legado ancestral africano e afro-brasileiro. No texto trabalhamos com a escuta sensível, inspirado na abordagem italiana segundo a experiência de Reggio Emillia, e com o conceito de vivência de Lev Semenovitch Vigotsky, onde o conceito de vivência como é apreendido como caminho possível para uma educação libertadora, onde a tomada de consciência pela criança possibilita que ela entenda que é autora do próprio mundo. Uma realidade onde a escola valorize e dê visibilidade a infância afrodescendente pertencente as comunidades religiosas tradicionais. (shrink)
