Coronavirus disease cases and COVID-19-related deaths have been increasing worldwide since the outbreak in 2019. Before the mass vaccination campaign for COVID-19, the main methods for COVID-19 control in China were mass testing and quarantine. Based on the transmission mechanism of COVID-19, we constructed a dynamic model for COVID-19 transmission in two typical regions: Beijing and Xinjiang. We calculated the basic reproduction number R 0, proved the global stability of COVID-19 transmission via the Lyapunov function technique, and introduced the final (...) size. We assessed the effectiveness of mass testing and quarantine. Sensitivity analysis indicated that the more the people were tested per day, the larger is the quarantine proportionality coefficient, the earlier the source location was determined, and the better is the controlling effect. In addition, it was more effective to increase the coefficient of quarantine if the population density in the region was low. To eliminate the pandemic, the government has to expand testing and quarantine, requiring a large amount of continuous manpower, material, and financial resources. Therefore, new control measures should be developed. (shrink)

The aim of this study was to investigate the applicability of the planned behavior theory model and TPB-6 model of enhanced physical exercise in college students, and to explore the role of exercise commitment in the relationship between exercise intention and behavior, so as to provide theoretical and empirical support for college students to promotion exercise. The study participants were 581 college students are investigated with Theory of Planned Behavior Scale, Exercise Commitment Scale, and Physical Activity Rating Scale. Results showed (...) that the explanatory power of the TPB to exercise intention and exercise behavior is 0.70 and 0.52, respectively, and exercise intention was the primary factor to predict exercise behavior of college students. The Model fit of TPB-6 model is acceptable, compared with TPB 5-factor model, the predictive power of TPB-6 on behavioral intention increases from 70.0 to 75.0%, and the predictive power towards behavior raises from 52.0 to 59.0%. Exercise commitment has a partial mediating effect between exercise intention and behavior, which accounts for 26.89% of the total effect, but it has no moderating effect. In conclusion, this research demonstrates the TPB-5 model has good applicability among the college students, with exercise commitment variables, exercise intention can better predict college students’ exercise behavior, which can be used as the theoretical basis for the intervention on their exercise behavior.

One of the major arenas for debate within generative grammar is the nature of paradigmatic relations among words. Intervening in key debates at the interface between syntax and semantics, this book examines the relation between structure and meaning, and analyses how it affects the internal properties of words and corresponding syntactic manifestations. Adapting notions from the Evo-Devo project in biology (the idea of 'co-linearity' between structural units and behavioural manifestations) Juan Uriagereka addresses a major puzzle: how words can be (...) both decomposable so as to be acquired by children, and atomic, so that they do not manifest themselves as modular to adults.

Este volumen estudia el papel de Cristo en el dinamismo teológico de la acción. Lo hace a través de un análisis de los comentarios al Nuevo Testamento de Santo Tomás de Aquino. Con ello se pretende contribuir a la elaboración de un cristocentrismo moral dentro del proceso de renovación de la teología moral que se ha llevado a cabo en todo el siglo XX.

Revolución Conservadora Y Conservación Revolucionaria Juan Mayorga Ruano La memoria de las víctimas, nos dice Walter Benjamín en el conjunto de su obra, es la única base sobre la que se puede construir una política no reaccionaria. Una política para la humanidad. El presente trabajo se enmarca en el campo de la consideración filosófica de la historia. Se trata de una reflexión sobre el concepto de la historia según Benjamin.

Las guerras centroamericanas de la década de 1980 provocaron giros analíticos en las agendas intelectuales. En este trabajo estudio el caso de Ignacio Martín-Baró, psicólogo social y sacerdote jesuita de la Universidad Centroamericana (UCA) de El Salvador. Postulo que su propuesta de imprimir una perspectiva latinoamericana al pensamiento psicosocial derivó de la necesidad de comprender las crisis sociales surgidas con la guerra. Martín-Baró se interesó por el ‘mundo desgarrado de la vida cotidiana’ como lugar de análisis de los principales conflictos (...) sociales, entre los que destacó la tortura y la alta dosis de crueldad manifestada en el ejercicio de la violencia. Por último, analizo sus reflexiones sobre los impactos de la guerra en la salud mental, especialmente en la niñez, y subrayo su llamado de atención sobre el carácter cultural de la violencia y los desafíos que ello implicaba para la imaginación de un nuevo futuro de convivencia. Si bien fue un pensador en constante alerta sobre la importancia del análisis históricamente sustentado para comprender las crisis sociales, sus intervenciones intelectuales imaginaron un futuro de viabilidad histórica y de sostenibilidad de la vida para las mayorías con las que comprometió su quehacer.

This edition is designed to open the enchanting book to all readers of modern Spanish. Raymond Willis has regularized and brought the medieval text as close as possible, without falsification, to modern canons. The text is printed integrally, without annotation. Mr. Willis' English paraphrase, printed on facing pages, is written in syntactical constructions that exactly parallel the Spanish verses, and thus functions as both a glossary and a key to puzzling constructions. Originally published in 1972. The Princeton Legacy Library uses (...) the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

This book studies the notions of order and universe in the philosophy of Thomas Aquinas. It provides an overview of an array of metaphysical concepts in Aquinas such as relation, proportion, types of order, composition, whole and part. It is claimed that Aquinas' metaphysics is mainaly a metaphysics of the order of the universe.

Functionalism as a philosophical position has been recently applied to the case of emotion research. However, a number of objections have been raised against applying such a view to scientific theorizing on emotions. In this article, I argue that functionalism is still a viable strategy for emotion research. To do this, I present functionalism in philosophy of mind and offer a sketch of its application to emotions. I then discuss three recent objections raised against it and respond to each of (...) them. These objections claim that functionalism is intractable because (i) it does not support a scientifically interesting taxonomy of emotions for experimental settings, (ii) it is inherently teleological, and (iii) it cannot be falsified. I argue that these objections either rely on a simplified version of functionalism as a philosophical position or they pose challenges that functionalists can readily address. Lastly, I conclude by drawing some lessons these objections suggest for a tractable functionalist account of emotions. (shrink)

It is not only difficult to be a sports expert but also difficult to grow from a sports expert to a sports elite. Professional athletes are often concerned about the differences between an expert and an elite and how to eventually become an elite athlete. To explore the differences in brain neural mechanism between experts and elites in the process of motor behavior and reveal the internal connection between motor performance and brain activity, we collected and analyzed the electroencephalography findings (...) of 14 national archers and 14 provincial archers during aiming and resting states and constructed the EEG brain network of the two archer groups based on weighted phase lag index; the graph theory was used to analyze and compare the network characteristics via local network and global network topologies. The results showed that compared with the expert archers, the elite archers had stronger functional coupling in beta1 and beta2 bands, and the difference was evident in the frontal and central regions; in terms of global characteristics of brain network topology, the average clustering coefficient and global efficiency of elite archers were significantly higher than that of expert archers, and the eigenvector centrality of expert archers was higher; for local characteristics, elite archers had higher local efficient; and the brain network characteristics of expert archers showed a strong correlation with archery performance. This suggests that compared with expert archers, elite archers showed stronger functional coupling, higher integration efficiency of global and local information, and more independent performance in the archery process. These findings reveal the differences in brain electrical network topologies between elite and expert archers in the archery preparation stage, which is expected to provide theoretical reference for further training and promotion of professional athletes.

Intuitively, there is a difference between knowledge and mere belief. Contemporary philosophical work on the nature of this difference has focused on scenarios known as “Gettier cases.” Designed as counterexamples to the classical theory that knowledge is justified true belief, these cases feature agents who arrive at true beliefs in ways which seem reasonable or justified, while nevertheless seeming to lack knowledge. Prior empirical investigation of these cases has raised questions about whether lay people generally share philosophers’ intuitions about these (...) cases, or whether lay intuitions vary depending on individual factors (e.g. ethnicity) or factors related to specific types of Gettier cases (e.g. cases that include apparent evidence). We report an experiment on lay attributions of knowledge and justification for a wide range of Gettier Cases and for a related class of controversial cases known as Skeptical Pressure cases, which are also thought by philosophers to elicit intuitive denials of knowledge. Although participants rated true beliefs in Gettier and Skeptical Pressure cases as being justified, they were significantly less likely to attribute knowledge for these cases than for matched true belief cases. This pattern of response was consistent across different variations of Gettier cases and did not vary by ethnicity or gender, although attributions of justification were found to be positively related to measures of empathy. These findings therefore suggest that across demographic groups, laypeople share similar epistemic concepts with philosophers, recognizing a difference between knowledge and justified true belief.

Concerns with improper collection and usage of personal information by businesses or governments have been seen as critical to the success of the emerging electronic commerce. In this regard, computer professionals have the oversight responsibility for information privacy because they have the most extensive knowledge of their organization's systems and programs, as well as an intimate understanding of the data. Thus, the competence of these professionals in ensuring sound practice of information privacy is of great importance to both researchers and (...) practitioners. This research addresses the question of whether male computer professionals differ from their female counterparts in their self-regulatory efficacy to protect personal information privacy. A total of 103 male and 65 female subjects surveyed in Taiwan responded to a 10-item questionnaire that includes three measures: protection (protecting privacy information), non-distribution (not distributing privacy information to others), and non-acquisition (not acquiring privacy information). The findings show (1) significant gender differences exist in the subjects' overall self-regulatory efficacy for information privacy, and, in particular, (2) that female subjects in this study exhibited a higher level of self-regulatory efficacy than males for the protection and non-acquisition of personal privacy information. The identification of the factorial structure of the self-regulatory efficacy concerning information privacy may contribute to future research directed to examining the links between privacy efficacy and psychological variables, such as ethical attitude, ethical intention, and self-esteem. Studies can also be extended to investigate how different cultural practices of morality and computer use in men and women may shape the different development patterns of privacy self-efficacy. Understanding the different cultural practices may then shed light on the social sources of privacy competence and the appropriate remedies that can be provided to improve the situation. (shrink)
