For several examples of Hermitian operators, the issues involved in their possible self-adjoint extension are shown to conform with recognizable properties in the solutions to the associated classical equations of motion. This result confirms the assertion made in an earlier paper (Ref. 1) that there are sufficient classical “symptoms” to diagnose any quantum “illness.”.

Live streaming shopping, the streaming of real-time videos promoting products that consumers can purchase online, has recently been a booming area of e-commerce, especially during the COVID-19 pandemic. The success of live streaming e-commerce largely relies on the extent to which the broadcaster can get consumers engaged by the live stream. Thus, it is important to discover the antecedents of consumer engagement in such a context. Drawing on consumer engagement and neuroscience literature, this study used electroencephalography inter-subject correlation to explore (...) how broadcasters' entrepreneurial passion during live streaming videos influenced consumers' neural engagement as they watched the live streaming videos. We used the framework of displayed passion and preparedness from the entrepreneurial passion literature to predict consumer engagement. We found significant ISC for strong displayed passion, while preparedness had partially significant effects on the first, second, and summed components of ISC. The interaction effects of these two factors on the first and summed components of ISC were partially significant. Strong displayed passion and preparedness activated the left and right prefrontal regions of the consumers' brains. These findings indicate that broadcasters' displayed passion and preparedness can influence consumer engagement in live streaming e-commerce settings. Our findings suggest that a scientific approach could be used to improve a broadcaster's performance by testing ISC during rehearsals before live streaming. (shrink)

A varied air volume air-conditioning system comprises diverse input and/or output disturbances, which are commonly nonlinear, with large lag and uncertainty. Based on the traditional control methods, testing the controlling parameters of a VAV air-conditioning system is challenging. Sliding mode control could improve the robustness of the system due to the adaptive capacity of disturbance rejection. Moreover, the fuzzy algorithm could be employed to determine the stability of a sliding control system by adjusting the parameters in the approach rate, reducing (...) the switching frequency, and weakening chatter. Fuzzy sliding mode control is investigated in this paper to improve the performance of a VAV air-conditioning system. Simulation results verify that the sliding mode control is suitable for a VAV air-conditioning system to achieve good adaptability and robustness considering the influence of multiple external variable disturbances. In addition, the chattering of the system is improved after the introduction of fuzzy control. (shrink)

A hallmark of positive‐sense RNA viruses is the formation of membranous shelters for safe replication in the cytoplasm. Once considered invisible to the immune system, these viral shelters are now found to be antagonized through the cooperation of autophagy proteins and anti‐microbial GTPases. This coordinated effort of autophagy proteins guiding GTPases functions against not only the shelters of viruses but also cytoplasmic vacuoles containing bacteria or protozoa, suggesting a broad immune‐defense mechanism against disparate vacuolar pathogens. Fundamental questions regarding this process (...) remain: how the host recognizes these membranous structures as a target, how the autophagy proteins bring the GTPases to the shelters, and how the recruited GTPases disrupt these shelters. In this review, these questions are discussed, the answers to which will significantly advance our understanding of the response to vacuole‐like structures of pathogens, thereby paving the way for the development of broadly effective anti‐microbial strategies for public health.

Since the outbreak of the COVID-19 pandemic, the physical and mental health of older adults has been threatened. Promoting physical and mental health through physical activity has therefore become a strategy for healthy aging. In order to better understand the impact of the participation of older adults in physical activity, this paper selects different types of physical activity, and examines the relationship between them and subjective well-being through the analysis of the mediation effect of outdoor exercise environment and the regulating (...) effect of exercise form. In this cross-sectional study, a questionnaire survey was conducted in mainland China. The main data come from 903 older adults in five urban areas in Chengdu, Sichuan Province. The surveys were carried out using the Physical Activity Rating Scale, Newfoundland Subjective Well-Being Scale, Exercise Environment Scale, and Exercise Form Scale. SPSS was used for statistical analysis, linear regression analysis was adopted for processing data, and AMOS was used to establish a mediation model. The mediating variable is the outdoor exercise environment, and the moderating variable is exercise form; gender, age, education level, and monthly income were used as control variables. The study results showed that different physical activities were significantly, positively correlated with the subjective well-being of older adults ; among the activities, tai chi had the strongest effect on the subjective well-being of older adults. Outdoor exercise environment played a mediating role between different physical activity types and subjective well-being of older adults [tai chi: β = 0.030, 95% CI ; health qigong: β = 0.018, 95% CI ; walking and jogging: β = 0.034, 95% CI ]. Exercise form moderated the subjective well-being of older adults in different physical activities. The results of this study demonstrate that the outdoor exercise environment plays a mediating role between different physical activities and the subjective well-being of older adults, and the form of exercise can also moderate the impact of different physical activities on the subjective well-being of older adults. This study has enlightening significance for psychological intervention with older adults facing stress, anxiety and depression. (shrink)

The tourism economy has become a new driving force for economic growth, and film-induced tourism in particular has been widely proven to promote economic and cultural development. Few studies focus on analyzing the inherent characteristics of the economic and cultural effects of film-induced tourism, and the research on the dynamic mechanism of the sustainable development of film-induced tourism is relatively limited. Therefore, from the perspective of the integration of culture and industry, the research explores the dynamic mechanism of sustainable development (...) between film-induced culture and film-induced industry through a questionnaire survey of 1,054 tourism management personnel, combined with quantitative empirical methods. The conclusion shows that the degree of integration of culture and tourism is an important mediating role that affects the dynamic mechanism of sustainable development of film-induced tourism, and the development of film-induced tourism depends on the integration of culture and industry. Constructing a diversified industrial integration model according to local conditions and determining the development path of resource, technology, market, product integration, and administrative management can become the general trend of the future development of film-induced tourism.

The complexity of the Hedgehog (Hh) signaling cascade has increased over the course of evolution; however, it does not suffice to accommodate the dynamic yet robust requirements of differential Hh signaling activity needed for embryonic development and adult homeostatic maintenance. One solution to solve this dilemma is to apply multiple forms of post‐translational modifications (PTMs) to the core Hh signaling components, modulating their abundance, localization, and signaling activity. This review summarizes various forms of protein modifications utilized to regulate Hh signaling, (...) with a special emphasis on crosstalk between different forms of PTMs and their feedback regulation by Hh signaling.

High-definition transcranial direct current stimulation is a valid brain stimulation technology to optimize cognitive function. Recent evidence indicates that single anodal tDCS session enhances attention; however, the variation in attention produced by repeated anodal HD-tDCS over a longer period of time has not been explored. We examined the modulation of attention function in healthy young participants who received repeated HD-tDCS sustained for 4 weeks. The results showed a robust benefit of anodal HD-tDCS on executive control and psychomotor efficiency, but not (...) on orienting, alerting, or selective attention ; the benefit increased successively over 4 weeks; and the enhancement on executive control of each week was significant compared to baseline in the anodal group. In addition, the subjects’ performances on the test of executive control and psychomotor efficiency gradually restored to the initial level in the sham group, which appeared obviously from week 3, but the improvement of attention in the anodal group was persistent. We conclude that repeated anodal HD-tDCS provides a positive benefit on executive control and psychomotor efficiency and has obvious accumulative effect after 9 or more times intervention compared to sham HD-tDCS. Additionally, our findings might provide pivotal guidance for the formulation of a strategy for the use of repeated anodal HD-tDCS to modulate on attention function. (shrink)

ObjectiveThis study explores the relationship between physical exercise and school adaptation of junior middle school students and constructs a chain intermediary model through the intermediary role of psychological resilience and sports learning motivation.MethodsUsing the stratified cluster sampling method, 930 junior middle school students in Anhui Province were measured in group psychology by using the physical exercise rating scale, adolescent psychological resilience scale, physical learning motivation scale and school adaptation scale. The statistical software SPSS 23.0 and process plug-in were used for (...) statistical processing, and the common method deviation test was carried out by Harman single-factor control method. Finally, the bootstrap sampling test method and process plug-in were used to test the significance of intermediary effect.Results The direct prediction effect of physical exercise on school adaptation is remarkable ; psychological resilience and sports learning motivation are the intermediary variables of the relationship between physical exercise and school adaptation; psychological resilience and sports learning motivation play a chain mediation role in the relationship between physical exercise and school adaptation. The intermediary effect is composed of three indirect effects: physical exercise → psychological resilience → school adaptation, physical exercise → physical learning motivation → school adaptation, physical exercise → psychological resilience → physical learning motivation → school adaptation.ConclusionsPhysical exercise can directly improve the school adaptation of junior middle school students, which can also affect junior middle school students’ school adaptation indirectly through psychological resilience or sports learning motivation, and it can influence school adaptation through the chain mediation of psychological resilience and sports learning motivation.

ABSTRACT In this paper we explore how a public national media outlet, the British BBC, represents an international legal case which has a highly political nature. The case is US versus Huawei/meng Wanzhou, which took place between 2018 and 2021. Accusations were that the Chinese technology company committed fraud, leading the global HSBC bank to breach US sanctions against Iran. The charges were made by the US using what is called an ‘extraterritorial law’, which, while rejected as law by governments (...) around the world, is policed by US economic powers and control over international finance. Using Critical Discourse Analysis we show that, while the BBC presents much detail of legal process, the actual nature of the law the US uses to bring criminal charges against international companies and banks, is neither considered nor questioned. Our interest is how such a law, which has a huge influence over global trade and politics, is presented to the public in this particular case. We contribute to the position that the nature of laws, how they are used and known, must always be understood within the prevailing discourses of the moment. (shrink)

Social commerce has produced enormous economic benefits as well as challenges for organizations, individuals, and industries. However, social media usage does not necessarily generate users’ intention to purchase on social commerce websites. How social media usage influences users’ purchase intention on social commerce websites still deserves more scholarly attention and this seems particularly important when social commerce transcends borders and countries. Taking an interdisciplinary perspective, the current study adopted a survey research method and identified the roles of social media usage (...) in arousing users’ purchase intention on social commerce websites in a culturally diversified environment. The data was collected from 2,058 international students coming from 135 countries and was analyzed using MPLUS based structural equation modeling. The research unveils the pathway whereby social media usage serves to generate users’ purchase intention on social commerce websites. Importantly, users’ cultural intelligence has been found to play a significant role mediating the effects of social media usage on users’ intention. Further, cultural distance was found to attenuate the effects of social media usage on cultural intelligence. Based on the research findings, the study suggests that social commerce practitioners should be fully aware of the enabling roles of social media and cultural intelligence as well as the deterring role of cultural distance when arousing customers’ purchasing intention in cross-cultural business operations. Any measures facilitated by social media usage to improve international consumers’ cultural intelligence and mitigate the negative effects of cultural distance are supposed to be effective to enhance their purchasing intention. Accordingly, the study confirms the mutually melt and integrative relationships between information technology advancement and business prosperity in cross-cultural environment, which eventually contribute to sustainable development of society.

With the assistance of the corpus analysis tool Wmatrix 4.0, this paper analyzes the semantic categories of the top 10 commercial banks of China and the United States to figure out their social-cultural behavior in the Internet business context. It is discovered that both common and distinctive identities were constructed: the common identities include the professional financial service provider, responsible corporation for employees, and relevant communities with environmental and social consciousness, while the distinctive identities are manifested in the communication strategy, (...) style, and persuasion mode: The Chinese Commercial Banks adopted the proactive strategy for corporate identity construction, are prone to take hierarchical and impersonal communication style, and more focused on the “credibility appeal” and “rational appeal” in persuasion mode; the commercial banks of the United States are more reactive in the communication strategy, position themselves in short distance with the putative audience in communication style, and conform to the typical “affective appeal” regarding the persuasion mode. From the intercultural perspective, the distinctions are the representation of the peculiar high-context culture and low-context culture based on Hofstede's cultural dimensions theory. Chinese banks should try to shorten the cultural gap by adopting communication strategy in conformity with the local cultural when going global rather than sticking to the domestic communication strategy.

Live commerce is a phenomenally innovative form of social commerce in China. In this paper, the authors aim to explore the authenticity of live commerce. By employing a qualitative approach using in-depth interviews and grounded theory, 21 initial categories are classified into six core categories. Among them, authenticity-associated concepts are classified into explicit concepts and implicit concepts. Explicit concepts of authenticity are associated with objectively authentic cues, while implicit concepts of authenticity are associated with subjectively authentic experiences. Moreover, the study (...) explores the relationship between explicit concepts of authenticity and product commitment, as well as the relationship between implicit concepts of authenticity and affective commitment. Both of these paths are found to influence consumers' shopping-related behaviors. Although consumers can more easily perceive explicitly authentic cues than implicitly authentic experiences, this study suggests that the latter may be more effective in inducing shopping behaviors. In addition, the effect of streamer attractiveness on opinion leader building is addressed, while authenticity is found to be an alternative approach to attract consumers both for attractive and nonattractive streamers. Finally, the study addresses theoretical implications and practical implications as well as suggestions for future research. (shrink)

Leadership is considered as a significant antecedent of knowledge hiding in SMEs, but the differential dimension of leadership has been evidently neglected in both theoretical and empirical areas. Drawing on conservation of resource theory and social cognitive theory, this research investigates whether and how SME differential leadership influences subordinate knowledge hiding. Specifically, we analyze the underlying mechanisms of a chain-mediator—job insecurity and territorial consciousness and a boundary condition—leadership performance expectation. Multi-wave and multi-source data were collected from a sample of 704 (...) Chinese SME employees and 140 relevant leaders and applied HLM meso-mediational frameworks, and Bootstrap technique with non-parametric percentile residuals for deviation correction. The results show that differential leadership plays a potential role in promoting subordinate knowledge hiding through the serial intervening mechanism of job Insecurity and territorial consciousness in SMEs. Furthermore, the positive relationship between SME differential leadership and job insecurity becomes stronger among subordinates under higher leadership performance expectation; the positive indirect relationship between SME differential leadership and subordinate knowledge hiding is stronger with higher levels of leadership performance expectation. This study contributes to the existing academic literature by empirically analyzing the under-investigated correlation between differential leadership and subordinate knowledge hiding in SMEs, and by exploring the underlying mechanisms and a boundary condition.

Based on his experimental studies, Libet claims that voluntary actions are initiated by unconscious brain activities well before intentions or decisions to act are consciously experienced by people. This account conflicts with our common-sense conception of human agency, in which people consciously and intentionally exert volitions or acts of will to initiate voluntary actions. This paper offers an alternative interpretation of Libet's experiment. The cause of the intentional acts performed by the subjects in Libet's experiment should not be exclusively attributed (...) to special cerebral processes; conscious intentions formed at the beginning of the experiment, when the subjects received experimental instructions, must be taken into account. In addition, what the subjects were required to report was not a conscious intention or decision to act that conventionally figures in the etiology of voluntary action, but rather a perceived effective urge to move induced by specific experimental instructions. According to the alternative interpretation, the most suitable mental term correlated with the specific brain activity that precedes conscious, self-initiated voluntary bodily movements is volition. This account is supported by recent theories of function of the supplementary motor area . Therefore, the notion that we are the authors or originators of our own actions, which is fundamental to our common understanding of free will, moral responsibility and human dignity, can be preserved.

The study results of this article provide a reference for further researches on the risk assessment algorithm of college student entrepreneurship based on big data analysis. (shrink)

The concept of volition has a long history in Western thought, but is looked upon unfavorably in contemporary philosophy and psychology. This paper proposes and elaborates a unifying conception of volition, which views volition as a mediating executive mental process that bridges the gaps between an agent's deliberation, decision and voluntary bodily action. Then the paper critically examines three major skeptical arguments against volition: volition is a mystery, volition is an illusion, and volition is a fundamentally flawed conception that leads (...) to infinite regress. It is shown that all these charges are untenable and the arguments are far from decisive to dismiss the concept of volition. In addition, it is suggested that a naturalistic approach, which takes philosophical inquiry as continuous with the scientific study of volition, is a promising way to demystify volition. (shrink)

In this paper, it is examined how neuroscience can help to understand the nature of volition by addressing the question whether volitions can be localized in the brain. Volitions, as acts of the will, are special mental events or activities by which an agent consciously and actively exercises her agency to voluntarily direct her thoughts and actions. If we can pinpoint when and where volitional events or activities occur in the brain and find out their neural underpinnings, this can substantively (...) aid to demystify the concept of volition. After first discussing some methodological issues regarding whether it is possible to locate volition in the brain, various approaches by which neuroscientists and psychologists explore the neural correlates and substrates of volition are examined. Although different psychological conceptualizations of volition shape different perspectives toward understanding the functions of volition, the explorations of the neural basis of volition converge on certain common brain areas and structures. A unifying conception of volition that helps to make better sense of recent empirical findings is then suggested. (shrink)

Zhu Xi is the most important of the twelfth-century neo-Confucianists. Some consider him second only to Confucius himself in his importance to Chinese philosophy as a whole, since it is his interpretation of Confucius that has been canonical since his lifetime. This short book, modeled after the Burton Watson "Basic Writings" volumes for Zhuangzi, Xunzi, and Han Feizi, is an accessible, one-volume introduction to Zhu Xi's influential philosophical system designed especially for course use. In "classifying" Zhu Xi's conversations in the (...) Classified Conversations of Master Zhu, Li Jingde dedicated the first thirteen chapters to conversations explaining his general philosophical system. Readers are introduced to his metaphysics of principle (li), psychophysical stuff (qi), spiritual beings (guishen), human nature (xing), mind-heart (xin), and emotions (qing); and to his program of self-cultivation-that is, the curriculum that Confucians should follow to attain moral perfection. Gardner argues that these chapters constitute the best overview of Zhu Xi's basic philosophical teachings, and selections from them form the basis of his volume. Occasionally, they are supplemented with passages from the Collected Literary Writings of Master Zhu and from Zhu's commentaries on the Classics. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 63.1 (2002) 1-17 [Access article in PDF] What if the Father Commits a Crime? Rui Zhu Apparently, Socrates and Confucius respond similarly to the question if a son should turn in his father in the case of the father's misdemeanor. When Euthyphro, flaring his pride of his moral impartiality, tells Socrates that he is on his way to report his father because he (...) has thrown one of the household slaves into a ditch and left him bound there until he was dead, Socrates says, "Good Heaven! Certainly, Euthyphro, most men would not know how they could do this and be right. It is not the part of anyone to do this, but of one who is far advanced in wisdom." 1According to Socrates, only a man of high wisdom knows how to prosecute his father righteously, but Euthyphro does not appear to have this wisdom. When his interlocutor observes that an upright man in his state would bear witness against his father if he misappropriates a sheep, Confucius contradicts the interlocutor's understanding of uprightness by speaking in a matter-of-fact tone: "In my country the upright men are of quite another sort. A father will cover up for his son, and a son his father—which incidentally does involve a sort of up—rightness." 2Confucius stands on the same line with Socrates but seems the more radical of the two. Socrates does not directly refute Euthyphro and only suggests that he make sure he understands what he is doing before going any further. Socrates is not only typically Socratic—indirect and suggestive—but also sounds so reasonable that Euthyphro appears in contrast to be a reckless youth who harbors [End Page 1] only a faint understanding of morality. Confucius's response is more rigid, for he categorically dismisses an act of the Euthyphroian kind. He demands that father and son cover up for each other in the case of either one's guilt. Compared to Socrates, Confucius advocates the position that seems a little too strong and leaves no room for justice, while Socrates does not have that problem with justice. This is how we feel about Socrates and Confucius on our first impression. The prima facie observations that we make from the remarks of Socrates and Confucius seem both plain and unproblematic.By embedding these remarks into their respective social or philosophical cultures, this paper will show that our previous observations are not quite accurate. The apparent affinity of the Socratic and Confucian stances belies different underlying moral philosophies. We want to use their comments as bridges to explore the early Greek and Confucian ethics and show how different a picture we see after things are examined within their traditions.The issue of a possible father-son conflict may be treated as a case study of the early Greek (the Heroic era until the age of Socrates) and early Confucian (Confucius and Mencius) morals. There is a strong theme in the early Greek morals that allows, or sometimes demands, a son such as Euthyphro to prosecute his father for the sake of justice, because justice, instead of love (philein) or filial piety, is the governing principle in the early Greek ethics. Confucian ethics is founded on love (human-heartedness), which in turn is extended from the love between father and son. All moral principles including justice are derived from this extension of love. The mutual love of father and son then becomes the governing principle in the case of Confucianism. A Guilty Father: The Greek Motif The question, "What if the father commits a crime?" has a certain realistic aroma to a boy coming of age in the Hesiodic Greek world. That father has to be overcome by son before some relief from strife becomes possible is a familiar theme in Greek literature. In Hesiod's Theogony, Uranus (the sky) incurs hatred from all his newborn children since he hides them in their mother Gaia's womb and does not let them return to the light, for no reason...

This paper begins by reviewing dominant themes in current teaching of professional ethics in engineering education. In contrast to more traditional approaches that simulate ethical practice by using ethical theories to reason through micro-level ethical dilemmas, this paper proposes a pragmatic approach to ethics that places more emphasis on the practical plausibility of ethical decision-making. In addition to the quality of ethical justification, the value of a moral action also depends on its effectiveness in solving an ethical dilemma, cultivating healthy (...) working relationships, negotiating existing organizational cultures, and achieving contextual plausibility in everyday professional practice. This paper uses a cross-cultural ethics scenario to further elaborate how a pragmatic approach can help us rethink ethical reasoning, as well as ethics instruction and assessment. This paper is expected to be of interest to educators eager to improve the ability of engineers and other professional students to effectively and appropriately deal with the kinds of everyday ethical issues they will likely face in their careers.

With the internationalisation of the Chinese market, Confucian ethics began to draw researchers' attention. However, little research has been conducted in the specific application of Confucian ethics in marketing communication. This article fills in the research gap by examining how Confucian ethics underpins the discourse of Chinese Expo invitations. Chinese sales managers' views are incorporated into the analysis as substantiation of findings. Confucian ethics embraces both qing (emotion) and li (reason) and relevant ethical values such as guanxi (connections), qing, and (...) mianzi (face) play an important role for advertising Expos and trade fairs. The study also highlights the complexities of Chinese Expo advertising that is embedded in inviting behaviour. These findings shed light on understanding Confucian ethics in marketing communications in general and have implications for ethical international marketing and advertising practices. (shrink)
