The widespread application of QR code technology is best represented by the health codes used in China’s pandemic prevention and control. This technology has enhanced the country’s ability to manage the pandemic by achieving higher efficiency and accuracy. Unfortunately, a certain segment of the older population has encountered difficulties in adapting and maintaining their daily activities. This indicates the limitations of QR code technology in achieving social isolation. This article argues that for a more comprehensive pandemic prevention and control policy (...) system to be established, managing the implementation of this very technology should be done in a more humane fashion, i.e. under the guidance of three moral principles: benevolence, justice, and non-maleficence. By doing so, implementation of QR code technology is done in a way that is not only conducive to COVID-19 prevention and control but also mitigate marginalization of the older people. In the post-pandemic era, the socialization of digital technology will accelerate. Therefore, in the field of public health, we should direct attention not only to the fair distribution of resources but also to the issue of identity that arises due to digital divide. (shrink)

Increasing gender diversity in the boardroom has been promoted as a way to enhance corporate governance and risk management. This study empirically examines whether boards with more female directors play a role in reducing R&D risk. We first show that female directors help to reduce the positive relationship between R&D investment and future performance volatility. We then report that firms with more gender-diverse boards exhibit a lower adverse effect of R&D on the cost of debt. These results are robust to (...) endogeneity analysis, alternative measures of gender diversity and risky investment, and other sensitivity tests. Overall, our results suggest that female directors improve board effectiveness in risk management with respect to R&D investment. (shrink)

When we say “I know why he was late”, we know not only the fact that he was late, but also an explanation of this fact. We propose a logical framework of “knowing why” inspired by the existing formal studies on why-questions, scientific explanation, and justification logic. We introduce the Kyi\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${{\mathcal {K}}{}\textit{y}}_i$$\end{document} operator into the language of epistemic logic to express “agent i knows why φ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} (...) \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\varphi $$\end{document}” and propose a Kripke-style semantics of such expressions in terms of knowing an explanation of φ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\varphi $$\end{document}. We obtain two sound and complete axiomatizations w.r.t. two different model classes depending on different assumptions about introspection. Finally we connect our logic with justification logic technically by providing an alternative semantics and an in-depth comparison on various design choices. (shrink)

Emergency online education has been adopted worldwide due to coronavirus disease 2019 pandemic. Prior research regarding online learning predominantly focused on the perception of parents, teachers, and students in tertiary education, while younger children’s perspectives have rarely been examined. This study investigated how family, school, and individual factors would be associated with primary school students’ satisfaction, perceived effectiveness, and preference in online learning during COVID-19. A convenient sample of 781 Hong Kong students completed an anonymous online survey from June to (...) October 2020. Logistic regression was conducted for 13 potential factors. Results indicated that only 57% of students were satisfied with their schools’ online learning arrangement and 49.6% regarded the online learning as an effective learning mode. Only 12.8% of students preferred online learning, while 67.2% of students preferred in-person schooling. Multiple analyses suggested that teacher–student interaction during online classes was positively associated with students’ satisfaction, perceived effectiveness, and preferences in online learning. Compared to grades 1–2 students, grades 3–6 students perceived more effectiveness and would prefer online learning. Happier schools were more likely to deliver satisfying and effective online education. Students who reported less happiness at school would prefer online learning, and students who reported less happiness at home would be less satisfied with online learning and reflected lower effectiveness. Teachers are encouraged to deliver more meaningful interactions to students and offer extra support to younger children during online classes. Primary schools and parents are encouraged to create a healthy and pleasant learning environment for children. The government may consider building up happy schools in the long run. The study findings are instrumental for policymakers, institutions, educators, and researchers in designing online education mechanisms. (shrink)

In decision-making involving multiple criteria or attributes, a decision maker first identifies all relevant evaluative attributes in making decisions. Then, a dominance principle is often invoked whenever applicable: whenever an option x is better than an option y in terms of some attribute and no worse than y in terms of any other attributes, x is judged to be better than y. If, however, this dominance principle is not applicable, then the decision maker determines the relative importance between the identified (...) evaluative attributes, consults with contextual features of the options under consideration, and makes a decision. It is shown that the combination of these principles runs into problems in the presence of rationality properties, such as transitivity, and a weak continuity requirement on decisions. The paper gives examples from welfare economics, and theories of individual and group decisions. (shrink)

El arte de los jardines tradicionales chinos se basa en la rigurosa e inteligente composición de los elementos arquitectónicos y naturales para crear un hermoso entorno que integre armoniosamente con las diferentes disciplinas artísticas. La cultura es el pilar más importante que sustenta la base conceptual de estos jardines y que es reflejada tanto en el diseño general del jardín como en los detalles de los elementos que lo configuran. Podemos decir que los jardines tradicionales son productos en los que (...) se concentran la cultura y la sabiduría milenaria del pueblo chino. En este artículo analizaremos el jardín tradicional chino mediante las manifestaciones culturales de la concepción del cosmos, el principio de la armonía entre el hombre y la naturaleza, la ocultación y el simbolismo de los elementos del jardín.

Resumen: Como educación estética, la educación musical no sólo necesita transmitir la belleza del arte, sino que también es una forma educativa de transmitir la belleza de la vida. Por lo tanto, con base en la estética de la vida y la connotación de la vida de la educación, la investigación discute la orientación de la vida de la educación musical de varios niveles desde múltiples perspectivas. La investigación analiza la estética vital de la música desde tres aspectos: lo limitado (...) y lo infinito, la existencia cultural del espíritu humanista y el isomorfismo del estado de vida. La discusión sobre la connotación de la vida educativa parte de tres aspectos: sobrevivencia, vivir y vivir. Sobre esta base, la investigación integra las dos teorías anteriores y discute la experiencia subjetiva-comunicación, cogniy emoción cognitiva en la educación musical. A través de la elaboración básica de la visión de vida de la educación musical, se puede encontrar que la educación musical es ayudar a los estudiantes a seguir una vida llena de arte, ayudándoles a desarrollarse armoniosamente.

Resumen: La filosofía China es una filosofía de la ecología. El problema fundamental de la filosofía China es la relación entre el cielo y el hombre, es decir, la relación entre la naturaleza y el hombre. Esto es evidente en las principales escuelas de la filosofía China, como el confucianismo y el taoísmo. Una correcta comprensión y evaluación de la filosofía ecológica China tiene un importante significado práctico para nosotros para reflexionar sobre el desequilibrio ecológico y el deterioro ambiental causado (...) por la civilización industrial creada bajo la guía del concepto mecánico de naturaleza y antropocentrismo, y para reexaminar la forma de la existencia humana, el desarrollo, el pensamiento y los valores. Este artículo tiene como objetivo explorar los elementos de la eco-filosofía en la filosofía China y analizar su influencia en el concepto, el valor y la práctica de la civilización ecológica.

The safety and stability of the power supply system are affected by some faults that often occur in power system. To solve this problem, a criterion algorithm based on the chaotic neural network and a fault detection algorithm based on discrete wavelet transform are proposed in this paper. MATLAB/Simulink is used to establish the system model to output fault signals and travelling wave signals. Db4 wavelet decomposes the travelling wave signals into detail signals and approximate signals, and these signals are (...) combined with the two-terminal travelling wave location method to achieve fault location. And the wavelet detail coefficients are extracted to input to the proposed chaotic neural network. The results show that the criterion algorithm can effectively determine whether there are faults in the power system, the fault detection algorithm has the capabilities of locating the system faults accurately, and both algorithms are not affected by fault type, fault location, fault initial angle, and transition resistance.

In order to solve the problem of node information loss during user matching in the existing user identification method of fixed community across the social network based on user topological relationship, Two-Stage User Identification Based on User Topology Dynamic Community Clustering algorithm is proposed. Firstly, we perform community clustering on different social networks, calculate the similarity between different network communities, and screen out community pairs with greater similarity. Secondly, two-way marriage matching is carried out for users between pairs of communities (...) with high similarity. Then, the dynamic community clustering was performed by resetting the different community clustering numbers. Finally, the iteration is repeated until no new matching user pairs are generated, or the set number of iterations is reached. Experiments conducted on real-world social networks Twitter-Foursquare datasets demonstrate that compared with the global user matching method and hidden label node method, the average accuracy of the proposed UIUTDC algorithm is improved by 33% and 26.8%, respectively. In the case of only user topology information, the proposed UIUTDC algorithm effectively improves the accuracy of identity recognition in practical applications. (shrink)

This research explored the influencing factors of gender swapping among female players in online games and their impact on online gaming behavior. Based on an online survey of 3,658 female players in China, we found that perceived benefits and the Tanbi tendency, a psychological indulgence in enjoying novels, comics, or series on love and sex between attractive males, were the most important factors for female players to employ male avatars. Sexual orientation, perceived anonymity, and perceived tolerance also had a significant (...) influence on gender swapping. Different from the practical benefits perceived by men who use female avatars in online games, the perceived benefit for female players who use male avatars was to avoid gender discrimination. In order to obtain more freedom and fairer treatment, they chose male avatars for a better experience. Female players with a higher degree of gender swapping showed a stronger aggressiveness and dominant “hyper-masculinity” behavior tendency in the game. Though online virtual worlds may be a convenient place for females to experience gender equality through gender swapping, the findings of this study suggest that gender swapping in games may, to some extent, perpetuate or even reinforce gender stereotypes in the real world.

The micro-level corporate social responsibility (CSR) literature has underscored the economic benefits of an organization's CSR investments, such as bolstering employees' organizational commitment and improving work performance. Yet, research on the potential influence of CSR in fostering socially oriented outcomes among employees has been rather scarce. This study aims to investigate the influence of CSR on employees' internal whistleblowing behaviors and the underlying mechanisms. A three-time-point survey was distributed across the service, manufacturing, construction, and financial insurance industries in Chinese enterprises. (...) The findings reveal that both internal and external CSR positively impact employees' internal whistleblowing behaviors through the mediating role of moral courage, with internal CSR demonstrating a stronger effect. Organizational loyalty positively moderates the mediating role of moral courage in the relationship between internal CSR/external CSR and internal whistleblowing behaviors. Theoretically, this study presents a pioneering endeavor in establishing the link between CSR and employees' internal whistleblowing behaviors, underscoring the significant role that employees' perceptions of CSR play in enhancing societal well-being and ethical governance. Besides contributing to the micro-level CSR literature, this study also provides practical insights for organizations seeking to leverage CSR as a tool for promoting employees' ethical conduct.

This study was conducted to investigate the relationship between posttraumatic growth, resilience, positive coping style, and self-efficacy among the primary caregivers of children with developmental disorders in Chongqing, China. A total of 198 primary caregivers aged from 22 to 66 years old, including 155 females and 43 males, were enrolled. The Posttraumatic Growth Inventory, Connor-Davidson Resilience Scale-10, Simplified Coping Style Questionnaire, and General Self-Efficacy Scale were used for data collection. The results found that PTG could be positively predicted by resilience. (...) Positive coping style and self-efficacy mediated the relationship between resilience and PTG. The different levels of PTG were determined by the resident location, monthly income and education of the primary caregivers. The results suggest that it is critical to improve the mental health of the primary caregivers of children with developmental disabilities. Our results also provide a scientific basis for future research. (shrink)

Cảm xúc là yếu tố cơ bản thúc đẩy con người đưa ra quyết định và xử lý thông tin. Sợ hãi là một trong những cảm xúc phổ biến nhất ảnh hưởng đến hành vi của nhà đầu tư cá nhân trên thị trường chứng khoán. Mặc dù nhiều nghiên cứu đã được thực hiện để khám phá tác động của nỗi sợ hãi đối với hiệu quả đầu tư và hành vi giao dịch của nhà đầu tư cá (...) nhân, nhưng vẫn còn rất ít thông tin về các yếu tố ảnh hưởng đến nỗi sợ hãi của nhà đầu tư cá nhân trong thời kỳ thị trường sụt giảm (hoặc những giai đoạn cực kỳ biến động). Vì thế, nghiên cứu này được thực hiện để tìm hiểu liệu các nguồn thông tin ảnh hưởng đến quyết định đầu tư của nhà đầu tư có ảnh hưởng đến sự sợ hãi của họ khi khủng hoảng xảy ra hay không. Nghiên cứu đã sử dụng phương pháp phân tích Bayesian Mindsponge Framework (BMF) trên bộ dữ liệu từ 1526 nhà đầu tư Trung Quốc và Việt Nam. Kết quả nghiên cứu chỉ ra rằng các nhà đầu tư tiếp cận các loại thông tin khác nhau khi đưa ra quyết định đầu tư sẽ ảnh hưởng đến tần suất phản ứng sợ hãi khác nhau. Cụ thể, các nhà đầu tư tham khảo thông tin từ chuyên gia hoặc tự phân tích khi đưa ra quyết định đầu tư ít bị đóng băng (biểu hiện của tâm lý sợ hãi) hơn trong thời kỳ thị trường sụt giảm. Ngược lại, những người đưa ra quyết định đầu tư dựa trên thông tin từ người quen hay bạn bè và trực giác sẽ bị đóng băng thường xuyên hơn. Kết quả nghiên cứu này giúp gợi ý nhà đầu tư cá nhân nên trang bị cho mình các kiến thức về tài chính cũng như tham khảo các ý kiến chuyên gia trên thị trường, hoặc những nguồn thông tin đáng tin cậy, khi đưa ra quyết định đầu tư. Bên cạnh đó, cơ quan quản lý thị trường cần có hoạt động phổ cập kiến thức về thị trường chứng khoán, hạn chế ảnh hưởng của các kênh thông tin không chính thống, và khuyến khích nhà đầu tư ít kinh nghiệm mua chứng chỉ quỹ của các quỹ đầu tư.

With the increasing volume of web services in the cloud environment, Collaborative Filtering- based service recommendation has become one of the most effective techniques to alleviate the heavy burden on the service selection decisions of a target user. However, the service recommendation bases, that is, historical service usage data, are often distributed in different cloud platforms. Two challenges are present in such a cross-cloud service recommendation scenario. First, a cloud platform is often not willing to share its data to other (...) cloud platforms due to privacy concerns, which decreases the feasibility of cross-cloud service recommendation severely. Second, the historical service usage data recorded in each cloud platform may update over time, which reduces the recommendation scalability significantly. In view of these two challenges, a novel privacy-preserving and scalable service recommendation approach based on SimHash, named SerRecSimHash, is proposed in this paper. Finally, through a set of experiments deployed on a real distributed service quality dataset WS-DREAM, we validate the feasibility of our proposal in terms of recommendation accuracy and efficiency while guaranteeing privacy-preservation.

La Crisis es aquel momento en que los relatos impuestos que habian dotado de sentido a la existencia individual y colectiva se resquebrajan. Las interpretaciones que sustentaban la sociedad, muchas veces impuestas de manera violenta, dejan de ser satisfactorias. La Crisis es, ademas, la oportunidad para alumbrar nuevos relatos, interpretaciones, que vengan a sustituir a aquellos que se rompen. Ese es el presente que vivimos, desde donde proyectamos nuestro compromiso con el futuro. Por ello esta obra se propone aportar algunas (...) visiones en torno a la situacion social y politica, en torno a la vida en comun, pero tambien acerca del interpretar, del comprender, del dotar de sentido a la existencia y a lo que esta por venir, con la voluntad de que sea para todos posible crear nuevos mundos, darnos nuevas narraciones y, en definitiva, construir alli donde solo hay escombros.
