Objectives: The present study aimed to systematically analyze the effects of physical activity on executive function, working memory, cognitive flexibility, and activities of daily living in Alzheimer's disease patients and to provide a scientific evidence-based exercise prescription.Methods: Both Chinese and English databases were used as sources of data to search for randomized controlled trials published between January 1980 and December 2019 relating to the effects of physical activity on executive function, working memory, cognitive flexibility, and ADL issues in AD patients. (...) Sixteen eligible RCTs were ultimately included in the meta-analysis.Results: Physical activity had significant benefits on executive function [standard mean difference = 0.42, 95% confidence interval 0.22–0.62, p < 0.05], working memory, cognitive flexibility, and ADLs among AD patients. Subgroup analysis indicated that, for executive function issues, more than 60 min per session for 16 weeks of moderate-to-high-intensity dual-task exercises or multimodal exercise had a greater effect on AD patients. For working memory and cognitive flexibility issues, 60–90 min of moderate-intensity dual-task exercises 1–4 times/week was more effective. For ADL issues, 30–90 min of multimodal exercise at 60–79% of maximal heart rate 3–4 times/week had a greater effect on AD patients.Conclusions: Physical activity was found to lead to significant improvements in executive function, working memory, cognitive flexibility, and ADLs in AD patients and can be used as an effective method for clinical exercise intervention in these patients. However, more objective, scientific, and effective RCTs are needed to confirm this conclusion. (shrink)

The complex chaotic dynamics and multistability of financial system are some important problems in micro- and macroeconomic fields. In this paper, we study the influence of two-delay feedback on the nonlinear dynamics behavior of financial system, considering the linear stability of equilibrium point under the condition of single delay and two delays. The system undergoes Hopf bifurcation near the equilibrium point. The stability and bifurcation directions of Hopf bifurcation are studied by using the normal form method and central manifold theory. (...) The theoretical results are verified by numerical simulation. Furthermore, one feature of the proposed financial chaotic system is that its multistability depends extremely on the memristor initial condition and the system parameters. It is shown that the nonlinear dynamics of financial chaotic system can be significantly changed by changing the values of time delays. (shrink)

Focusing on Hangzhou, a famous tourist city in China, in this study, four regression models were constructed through four items of tourist loyalty to investigate the influence of tourist perceptions and characteristics on male and female tourist loyalty to shared bicycles. A questionnaire survey and ordered logistic regression model techniques were used. Survey data from 467 tourists indicated that there were significant differences between male and female tourists. For male tourists, their willingness to reuse shared bicycles was positively correlated with (...) ease of access to cycles, environmental awareness, psychological benefit, and management provision; however, their willingness to recommend shared bicycles was only affected by environmental awareness, psychological benefit, and management provision. Among female tourists, willingness to reuse shared bicycles was affected by ease of access to cycles, environmental awareness, and rule adherence, while their willingness to recommend shared bicycles was affected by ease of access to cycles, environmental awareness, psychological benefit, and managerial provision. In addition, female tourists’ socio-demographic and behavioral characteristics had a significant impact on their loyalty, among which length of stay in Hangzhou and education were significant in the four regression models, and number of visits to Hangzhou had a positive impact on female tourists’ willingness to reuse. In addition, female tourists who used Hellobike had higher willingness to reuse and recommend than those who used Mobike. For male tourists, only length of stay in Hangzhou had a significant impact on their reuse intention. The current study extends the theory of attribution to explore the factors which may affect tourist’s loyalty to bicycle-sharing from the perspectives of tourists’ perceptions. It will provide further support to decision makers in the development of new shared-bicycle systems at Chinese tourist destinations, with the aim of strengthening tourist loyalty to shared-bicycle programs.

As a worldwide epidemic in the digital age, cyberbullying is a pertinent but understudied concern—especially from the perspective of language. Elucidating the linguistic features of cyberbullying is critical both to preventing it and to cultivating ethical and responsible digital citizens. In this study, a mixed-method approach integrating lexical feature analysis, sentiment polarity analysis, and semantic network analysis was adopted to develop a deeper understanding of cyberbullying language. Five cyberbullying cases on Chinese social media were analyzed to uncover explicit and implicit (...) linguistic features. Results indicated that cyberbullying comments had significantly different linguistic profiles than non-bullying comments and that explicit and implicit bullying were distinct. The content of cases further suggested that cyberbullying language varied in the use of words, types of cyberbullying, and sentiment polarity. These findings offer useful insight for designing automatic cyberbullying detection tools for Chinese social networking platforms. Implications also offer guidance for regulating cyberbullying and fostering ethical and responsible digital citizens. (shrink)

The writers of the Huainanzi 淮南子 show that emotions are based on resonance. In this ancient Chinese text, emotional expressions are considered natural phenomena; however, at the same time, they are sometimes evaluated negatively. It states that sometimes, not only emotions stemming from desires but also emotional expressions in daily lives must be controlled. This is due to the following prescriptions stemming from the art of rulership: (1) a ruler must clearly and distinctly recognize a situation. Emotional expressions lose the (...) Quintessential Spirit (jingshen 精神), which mediates the recognition of the situation; and (2) the intention must not be revealed to the ruler’s vassals. The concept of heart (xin 心) in the Huainanzi, on the foundation called the “theory of cultivation” of Daoism, is influenced by the art of rulership from Legalism. (shrink)

ObjectiveThis pilot study aimed to evaluate the efficacy of a digital cognitive behavioral therapy in patients with cancer experiencing sleep problems.MethodsA total of 57 participants aged 25–65 years were randomly assigned to three groups—21 participants to a dCBT program, 20 participants to an app-based attentional control program, and 16 participants to a waitlist control group—and evaluated offline before and after the program completion. Of the 57 participants, there were a total of 45 study completers, 15 participants in each group. The (...) dependent variables were sleep quality scores, measured by the Pittsburgh Sleep Quality Index and health-related quality of life scores, measured using the Short-Form 36, and attentional bias scores from a dot-probe computer task.ResultsFor both the intention-to-treat and study-completers analyses, a significant increase supported by a large effect size was found in the quality of sleep score of the HARUToday Sleep group compared to both the app-based attentional control and the waitlist control group. However, no significant changes were found in the quality of life and attentional bias scores.ConclusionOur results suggest that the HARUToday Sleep app has the potential to serve as an intervention module to enhance the sleep quality of patients with cancer experiencing sleep problems.

What is feminist philosophy? A difficult question for feminist scholars in China. Women's studies in the Chinese mainland are characteristically policy‐oriented, geared to practical concerns and moral urgency. Empirical research projects engage many pressing social issues related to the changing situation of women in a rapid marketification of society and commercialization of culture since the post‐1978 reform movement. Here are some examples: migrant female workers and their working conditions in the urban centers; the impact of rural industrialization on women in (...) the countryside: discrimination against women in employment as well as in other aspects of social life; marriage and sexual relations. What follows in this article however, represents an effort to identify and categorize trends in emerging feminist theories. The main questions that might be seen as in one way or another philosophical are located in the historical context of the transformation of Chinese socialism. As we have only very limited access to publications in Hong Kong and Taiwan, to avoid mispresentation we regret that we cannot discuss the feminist work developed in these areas. (shrink)

John Rawls presents a liberal conception of international justice in his book The Law of Peoples, and this liberal conception of international justice has inspired a variety of responses from various perspectives. However, it seems that most such responses come from western perspectives, and that there is hence a corresponding paucity of seriously challenging responses based on non-western traditions. This paper aims to analyze Rawls’s liberal conception of international justice in view of the concept of natural justice expressed within the (...) Book of Change in order to illuminate the limitations and problems of Rawls’s conception in practice as well as in theory. Rawls employs the idea of political liberalism to construct a liberal conception of international justice that can be applied to a society of societies. Rawls addresses the eight principles for justice among free and democratic peoples, which have been historically accepted by western peoples. He admits that these principles are incomplete. There is no theoretical order among the eight principles equivalent to the lexical order of the two principles of justice in A Theory of Justice. There are no guidelines or basic principles for resolving the problem of priority that arises when the principles are themselves in conflict with one another. This situation may generate competing conceptions of justice within the society of peoples. Rawls mentions natural justice in his explanation for the extension of liberal political principles to decent hierarchical peoples. He takes as an example of natural justice the rule of formal equality that “similar cases be treated similarly.” He does not develop any further the idea of natural justice for his theory of international justice, which could potentially span the gap between his ideal theory and non-ideal theory, or enhance the reasonableness of his international justice, especially for non-liberal peoples. The Book of Change expresses the idea of natural justice that underlies the principle of Yin-Yang, which differs fundamentally from the liberal contract paradigm. The paper will argue that the idea of natural justice should be seriously considered for justice among peoples since it can provide the bedrock for criticizing non-public reason as well as public reason.

Due to fresh foods' unique characteristics, where quality, freshness, and perishability are the main concerns, consumers are more inclined to choose offline channels for purchasing foods. However, it is not well-understood how these behaviors are affected by the adverse external environment, e.g., smog pollution. Fine particulate matters on smog days would irritate the respiratory tract and pose health risks to people, triggering negative emotions such as sadness and depression. People tend to stay in a clean indoor environment on smog days. (...) An adverse external environment is causing a gradual change in people's habits and emotions. Still, its impact on shopping behaviors is a complex process in need of further study. The study fills this gap by examining the impact of smog pollution on customer channel choice. Based on data from an e-commerce retailer that operates in both online and offline channels. We find that the degree of smog pollution has a significant positive effect on online channel purchasing at aggregated store-, product-, and individual- levels; moreover, the retailer's in-store interactive activities would restrain this positive relationship; variation of product pricing and customers' healthy eating tendency would pronounce the positive association between smog and online purchasing. These results can serve as a reference for retailers to adjust channel strategies in the face of harsh external conditions. (shrink)

Embodied cognition theory posits that concept representations inherently rely on sensorimotor experiences that accompany their acquisitions. This is well established through concrete concepts. However, it is debatable whether representations of abstract concepts are based on sensorimotor representations. This study investigated the causal role of associated motor experiences that accompany concept acquisition in the involvement of the motor system in the abstract verb processing. Through two experiments, we examined the action–sentence compatibility effect, in the test phase after an increase in motor (...) features during the learning phase for abstract verbs with low motor features or novel words with no conceptual features at all. After associated motor experiences were added in the word learning phase, action–sentence compatibility effect was found in the semantic processing tasks during the test phase for abstract verbs and novel words. This was lacking in the word font color judgment task requiring no semantic processing. Coupled with our previous study, these findings suggest that motor features formed during word learning could causally affect embodiment in the motor system for abstract verbs, and reactivation of motor experiences in abstract verb processing depends on a given task’s demands. Our study supports the view that conceptual representations, even abstract concepts, can be grounded in sensorimotor experiences. (shrink)

We clarify different definitions of the density matrix by proposing the use of different names, the full density matrix for a single-closed quantum system, the compressed density matrix for the averaged single molecule state from an ensemble of molecules, and the reduced density matrix for a part of an entangled quantum system, respectively. We show that ensembles with the same compressed density matrix can be physically distinguished by observing fluctuations of various observables. This is in contrast to a general belief (...) that ensembles with the same compressed density matrix are identical. Explicit expression for the fluctuation of an observable in a specified ensemble is given. We have discussed the nature of nuclear magnetic resonance quantum computing. We show that the conclusion that there is no quantum entanglement in the current nuclear magnetic resonance quantum computing experiment is based on the unjustified belief that ensembles having the same compressed density matrix are identical physically. Related issues in quantum communication are also discussed. (shrink)

Throughout the COVID-19 pandemic, shortages of scarce healthcare resources consistently presented significant moral and practical challenges. While the importance of vaccines as a key pharmaceutical intervention to stem pandemic scarcity was widely publicized, a sizable proportion of the population chose not to vaccinate. In response, some have defended the use of vaccination status as a criterion for the allocation of scarce medical resources. In this paper, we critically interpret this burgeoning literature, and describe a framework for thinking about vaccine-sensitive resource (...) allocation using the values of responsibility, reciprocity, and justice. Although our aim here is not to defend a single view of vaccine-sensitive resource allocation, we believe that attending critically with the diversity of arguments in favor (and against) vaccine-sensitivity reveals a number of questions that a vaccine-sensitive approach to allocation should answer in future pandemics.

Given that women CEOs are usually more risk averse, engage less in opportunistic behavior, and provide higher quality earnings than men CEOs, we argue that firms with women CEOs are likely to face lower operational and information risk and thus enjoy cheaper external funds. Using a large sample of Chinese A-share listed firms operating from 2006 to 2012, we find consistent evidence that Chinese banks tend to impose lower loan costs on firms with women CEOs compared to firms with men (...) CEOs. This effect is more pronounced for non-state-owned enterprises than for state-owned enterprises, for firms without political connections than for firms with political connections, and during non-crisis periods. We do not find any significant effects for firms with women chairpersons, CFOs, or directors. (shrink)

Research on delinquency reduction often highlights the importance of identifying and sanctioning antisocial and illegal activities so as to reduce the likelihood of future offending. The rise of digital technology complicates the process of detecting cybercrimes and technology enabled offenses, as individuals can use devices from anywhere to engage in various harmful activities that may appear benign to an observer. Despite the growth of cybercrime research, limited studies have examined the extent to which technology enabled offenses are detected, or the (...) behavioral and attitudinal factors associated with being unobserved or caught for one’s actions. The current study addresses this gap in the literature by estimating a multinomial regression model for self-reported computer hacking behavior and the likelihood of those actions being detected in a large international sample of juveniles (N = 51,059). The findings demonstrate significant differences between youth who hack without detection compared to those who are caught. The implications of this analysis for our understanding of cybercrime and its relationship to traditional delinquency are explored in depth. (shrink)

Zen philosophy of language is discussed by exploring the concepts of live and dead words, involvement with meaning and involvement with words, and the three mysterious gates as they are employed in Pojo Chinul's huatou meditation. A comparison is made between the Zen use of language and Merleau-Ponty's philosophy of visibility, Julia Kristeva's idea of the semiotic and the symbolic, and Kierkegaard's concept of anxiety, in an attempt to provide a paradigm to understand the Zen Buddhist vision.

The combination of decreased genotyping costs and prolific social media use is fueling a personal genetic testing industry in which consumers purchase and interact with genetic risk information online. Consumers and their genetic risk profiles are protected in some respects by the 2008 federal Genetic Information Nondiscrimination Act (GINA), which forbids the discriminatory use of genetic information by employers and health insurers; however, practical and technical limitations undermine its enforceability, given the everyday practices of online social networking and its impact (...) on the workplace. In the Web 2.0 era, employers in most states can legally search about job candidates and employees online, probing social networking sites for personal information that might bear on hiring and employment decisions. We examine GINA's protections for online sharing of genetic information as well as its limitations, and propose policy recommendations to address current gaps that leave employees? genetic information vulnerable in a Web-based world.

Der Name Hannah Arendt bezeichnet eine ebenso radikale wie originale Erneuerung der Frage nach der „politischen Freiheit”. Um es gleich zu sagen: Freiheit ist mit dem Politischen identisch und gleichursprünglich. „Der Sinn von Politik ist Freiheit.” Das heißt, die genuin menschliche Freiheit in dieser Welt ist nur politisch vollziehbar, während die Freiheit der einzige Existenz- und Rechtfertigungsgrund der Politik ist. Hannah Arendts Überlegungen über das Kriterium politischer Freiheit konzentrieren sich vor allem auf drei Kategorien: „Identität”, „Pluralität” und „Spontaneität”.
