High-tech industries often regard workers as their main source of value creation. In order to stimulate their employees' willingness to innovate and their innovative behavior and reduce the turnover intention, companies are now seeking to establish employer–employee relationships in which their employee's willingness to stay is not simply driven by extrinsic motivations. Therefore, it is an important topic in human resources for companies to implement measures that encourage employees to willingly devote themselves to their jobs and consider organizational growth as (...) a component of their career development. This study aimed to investigate the effect of person–organization fit and person–job fit on employees' innovative behavior and turnover intention via the mediators including job satisfaction and organizational commitment. Six hundred ninety-seven employees from China's eight major high-tech industries were examined in this study, and the empirical results were analyzed using partial least squares. Based on the results, it is suggested that the person–organization fit and person–job fit are both crucial factors affecting employees' job satisfaction and organizational commitment, which, in turn, increase employees' willingness to innovate in their jobs and reduce their turnover intentions. Furthermore, this study could serve as a reference for companies in selecting employees, promoting job satisfaction, and developing strategies for sustainable development. (shrink)

In this paper, we propose to incorporate the local attention in WaveNet-CTC to improve the performance of Tibetan speech recognition in multitask learning. With an increase in task number, such as simultaneous Tibetan speech content recognition, dialect identification, and speaker recognition, the accuracy rate of a single WaveNet-CTC decreases on speech recognition. Inspired by the attention mechanism, we introduce the local attention to automatically tune the weights of feature frames in a window and pay different attention on context information for (...) multitask learning. The experimental results show that our method improves the accuracies of speech recognition for all Tibetan dialects in three-task learning, compared with the baseline model. Furthermore, our method significantly improves the accuracy for low-resource dialect by 5.11% against the specific-dialect model. (shrink)

BackgroundCoronary heart disease is closely associated with cognitive impairment, especially in severe cases of heart failure. However, it is unclear whether cardiac systolic function plays a role in the relationship between pre-existing CHD and cognitive impairment in subjects without clinical heart failure.MethodsIn total, 208 subjects from the First Affiliated Hospital of Xi’an Jiaotong University were recruited from June 2014 to January 2015, and were divided into CHD and non-CHD groups according to the inclusion and exclusion criteria. The global cognitive function (...) of all subjects was assessed by the Mini-Mental State Examination and cognitive impairment was defined as the score lower than the cutoff value. Left ventricular ejection fraction was measured using transthoracic echocardiograms. The relationship among pre-existing CHD, LVEF, and cognitive impairment was analyzed by multivariate logistic regression.ResultsIn total, 34 subjects met the criteria of cognitive impairment. Univariate analysis showed that the cognitive impairment prevalence in the CHD group was significantly higher than that in the non-CHD group. Multivariate logistic analysis revealed that CHD was significantly associated with a higher risk of cognitive impairment after adjusting for confounds except for LVEF. However, the OR of CHD decreased when LVEF was further corrected as a continuous variable, and LVEF was negatively associated with the risk of cognitive impairment.ConclusionPre-existing CHD is associated with a higher risk of cognitive impairment, and such an association can be considerably explained by reduced LVEF. An impaired cardiac systolic function may play a key role in the relationship between CHD and cognitive impairment among patients with pre-heart failure conditions. (shrink)

Background: We described the prevalence of anxiety and depression related to COVID-19 pandemic among different types of population and examined their potential risk factors.Methods: A cross-sectional survey was conducted to collect demographic characteristics, exposure histories, and many other concerns about COVID-19. The Zung's self-rating anxiety scale and self-rating depression scale, followed by a four-step multiple logistic regression analysis was performed to identify factors associated with mental health outcomes.Results: Out of 3,303 participants, the quarantined people, community workstation staffs-policemen-volunteers and general public (...) reported higher percentages of depression than the general medical staff. Moreover, the quarantined people also showed higher prevalence of anxiety than the general public and the general medical staff. The quarantined people had the highest risk of anxiety and depression, whereas the self-rated health was negatively associated with the risks of anxiety and depression. Younger age group showed higher risks of anxiety and depression. People who had exposure history or contact from Hubei province after December 1, 2019, had family or friends engaged in front-line health care work, had confirmed case nearby were all more likely to suffer from anxiety. Moreover, the negligence or overindulgence toward the epidemic information was associated with a higher risk of depression and anxiety.Conclusions: Our findings show that the CPV and quarantined people were most at-risk population. We have identified that the young people, people with exposure histories and negligence or overindulgence toward epidemic information are in grave need of attention. (shrink)

Background: Both anxiety and depression in family caregivers of advanced cancer patients are common, and they have a negative influence on both the FCs and the patients. Some studies suggested that a variety of interventions could alleviate the psychological symptoms of FCs. However, there is no consensus on much more effective methods for intervention, and relatively high-quality research is blank in psychological problems of these population in China. The validity of mindfulness-based stress reduction and psychological consultation guided by the needs (...) assessment tool in the psychological status of caregivers will be compared in this study to select a more suitable intervention for the FCs of advanced cancer patients in China.Methods and Analysis: A randomized N-of-1 trial would be conducted at the Cancer Hospital, Chinese Academy of Medical Sciences. Fifty eligible FCs of advanced cancer patients will be recruited, and all will receive three cycles of psychological intervention treatment, with each cycle including both of MBSR and psychological consultation guided by the NST. MBSR and psychological consultation guided by the NST will be compared with each other in each cycle, and the intervention sequence will be based on the random number table generated after the informed consent has been completed. Each treatment period is 2 weeks, and the interval between different treatment cycles or treatment periods is 1 week. The self-reported scales are measured at the beginning and end of each treatment period, including the Self-Rating Anxiety Scale, the Self-Rating Depression Scale, Distress Thermometer, Zarit Burden Interview, Chinese version of the Medical Outcomes Study 12-item Short Form, and Family Carer Satisfaction with Palliative Care scale.Dissemination: The protocol of the study was approved by the Institutional Review Board of the Ethical Committee of the Cancer Hospital, Chinese Academic of Medical Science. The results will be published in a peer-reviewed medical journal. The study is registered at Chinese Clinical Trials Registry with the trial registration number chiCTR2000033707. This study employs an innovative methodological approach on the effectiveness of MBSR and psychological consultation guided by the NST for psychological status of FCs of advanced cancer patients. The findings of the study will be helpful to provide high-quality evidence-based medical data for psychological intervention of FCs of advanced cancer patients, and guide clinicians on best quality treatment recommendations.

This paper attempts to engage with theoretical discourses to address these intersections of gender, body, and space in the forefront of contemporary Chinese visual artists’ radical performances. From Cui Xiuwen’s scandalous video installation Lady’s of the female bathroom in Tianshang Renjian Hotel to Ma Liuming’s iconic androgynous walk on the Great Wall, contemporary Chinese visual/performance artists have challenged the limits and borders of body as art in radically experimental ways. Feminist art has been liberated from female painting in the post-socialist (...) era, and gender hierarchy and norms have been more profoundly critiqued in these performative events. Pressed by the post-socialist political conditions, market economy, the influence of western art in the era of late capitalism, and the Confucian-Taoist tradition, the Chinese artists have embarked on an experimental journey, attempting to articulate a newness of their complicated lived experiences and to call for social and political transformations.

Offers the first focused study of the shifei debates of the Warring States period in ancient China and challenges the imposition of Western conceptual categories onto these debates. In recent decades, a growing concern in studies in Chinese intellectual history is that Chinese classics have been forced into systems of classification prevalent in Western philosophy and thus imperceptibly transformed into examples that echo Western philosophy. Lin Ma and Jaap van Brakel offer a methodology to counter this approach, and illustrate their (...) method by carrying out a transcultural inquiry into the complexities involved in understanding shi and fei and their cognate phrases in the Warring States texts, the Zhuangzi in particular. The authors discuss important features of Zhuangzi’s stance with regard to language-meaning, knowledge-doubt, questioning, equalizing, and his well-known deconstruction of the discourse in ancient China on shifei. Ma and van Brakel suggest that shi and fei apply to both descriptive and prescriptive languages and do not presuppose any fact/value dichotomy, and thus cannot be translated as either true/false or right/wrong. Instead, shi and feican be grasped in terms of a pre-philosophical notion of fitting. Ma and van Brakel also highlight Zhuangzi’s idea of “walking-two-roads” as the most significant component of his stance. In addition, they argue that all of Zhuangzi’s positive recommendations are presented in a language whose meaning is not fixed and that every stance he is committed to remains subject to fundamental questioning as a way of life.

Abstract:Both Zhang Taiyan and Heidegger oppose the idea of unilinear teleological progress by unveiling the dimensions of decline embedded in modern (Western) civilization. In terms of the theory of dual "evolution," Zhang points out that accompanying the increase of good and happiness is the inevitable aggravation of evil and suffering. Critically appropriating Spengler, Heidegger diagnoses the current era as one of gigantic decline and speaks of Europe as the actualization of the decline of the West. Zhang attributes the meontological source (...) of evil and suffering to the abiding affective imprint and self-conceit, while Heidegger's thematization of decline is intimately bound up with his abiding concern with the history of Being. Confronted with the world of decline, Zhang puts forward a Zhuangzian proposal of "harmonizing between shi 是 and fei 非." In contrast, for Heidegger this decline at the same time offers the transition into the other inception of Western tradition. (shrink)

In this article, I introduce a new interpretation of the puzzling thesis “bai 白 ma 馬 fei 非 ma 馬 ” argued by Gongsun Long 公孫龍 in his essay “On White Horse.” I argue that previous interpretations, which can be grouped under the name of “attribute-object interpretations,” are not satisfactory, and that the thesis on the new interpretation is not about attributes or objects, but about names. My argument focuses on the disagreement over inseparability of white between Gongsun Long and (...) his interlocutor in the text of “On White Horse.” On my interpretation or the name interpretation, the disagreement is about whether constituents of a syntactically complex or multi-term name are separable or have their contextually independent meanings. Gongsun Long’s thesis makes perfect sense on my interpretation, and is supported by the text and other preserved texts collected in GongsunLong Zi 公孫龍子. The name interpretation can also make sense of some puzzling expressions of sophists in the classic period. (shrink)

In this article, I argue for a distinct and novel right-based account of risks and I call it the Sophisticated High-risk Thesis. I argue that there is a distinction between rights-infringing risk impositions and no-rights-infringing risk impositions. An action imposing a high risk of harm infringes rights, whereas an act imposing a low risk of harm does not. I also suggest three principles that govern the permissibility of highly risky actions. If a highly risky action meets the conditions specified by (...) any of these three principles, it can be justified. These principles are the consent principle*, the prevent disaster principle* and the reciprocity principle**. I show that the Sophisticated High-risk Thesis is, in general, better than the alternative Risk Thesis defended by McCarthy. (shrink)

With the increasing degrees A.I.s and machines are applied across different social contexts, the need for implementing ethics in A.I.s is pressing. In this paper, we argue for a pluralist hybrid model for the implementation of moral A.I.s. We first survey current approaches to moral A.I.s and their inherent limitations. Then we propose the pluralist hybrid approach and show how these limitations of moral A.I.s can be partly alleviated by the pluralist hybrid approach. The core ethical decision-making capacity of an (...) A.I. based on the pluralist hybrid approach consists of two systems. The first is a deterministic algorithm system that incorporates different moral rules for making explicit moral decisions. The second is a machine learning system that calculates the value of the variables required by the application of moral principles. The pluralist hybrid system is better than the existing proposals as (i) it better addresses the moral disagreement problem of the top-down approach by including different moral principles, while (ii) it reduces the opacity of ethical decision-making compared with a bottom-up system by implementing explicit moral principles for moral decision making.

ABSTRACT ‘Summer Davos’ meeting in China organised by the World Economic Forum is an annual event that brings together leading voices from the East and West in business, society, and politics. The economic-political challenges and geopolitical upheavals that intercepted temporarily and transnationally in the close-up to the 2016 Summer Davos meeting rendered this discursive event a site of particular political/ideological contestation. This study intends to make sense of the unobtrusive, pro- home-nation nationalist ideology manifested in the interpreted texts by Chinese (...) conference interpreters who bridge language gaps in situ in the meeting. These textual manifestations of nationalism are examined by interrogating how specific discursive strategies are deployed in connection with thematic contents about China, the interpreters’ home-nation, in relation to other countries. Fundamentally, Chinese interpreters’ nationalism finds its way into their linguistic means that realise their specific strategies of self-censoring, neutralising self-negativity, aggrandising self-positivity and accentuating the negative-other representation in relation to topics on national sovereignty, territorial integrity, diplomatic relations and economic/political positions, all of which are crucial to the interests of a nation.

Objectives: The corona virus disease-2019 pandemic spread globally, and we aimed to investigate the psychosocial impact on healthcare workers in China during the pandemic.Methods: In this systematic review and meta-analysis, we searched seven electronic databases for cross-sectional studies on psychosocial impact on HWs in relation to COVID-19 from January 1, 2020 to October 7, 2020. We included primary studies involving Chinese HWs during the pandemic, and data were extracted from the published articles. Our primary outcome was prevalence of anxiety, depression, (...) and stress disorders. We pooled prevalence value with their 95% confidence interval using random effect models and assessed study quality on the basis of an 11-item checklist recommended by the Agency for Healthcare Research and Quality. The study protocol was registered in PROSPERO.Results: We identified 25 articles comprising a total of 30,841 completed questionnaires and 22 studies for meta-analysis. The prevalence of anxiety, depression, and stress disorders was 34.4%, 31.1%, and 29.1% for HWs. The pooled prevalence of anxiety disorders for HWs from late January to early February was 46.4%, significantly higher than those in mid-term February and after late February. The pooled prevalence of depression disorders for HWs from late January to early February was 46.5%, significantly higher than those in mid-term February and after late February. HWs working in Hubei Province had a higher prevalence of anxiety and a lower prevalence of depression than those working in other regions. Nurses had a higher prevalence of anxiety and depression than other HWs.Conclusions: About one-third of HWs in China suffered anxiety, depression, and stress at the early epidemic of COVID-19. HWs in Hubei Province, especially nurses, had a higher prevalence of psychological disorders. During the pandemic, a negative psychological state may persist in a proportion of Chinese HWs, fluctuating with the control of the pandemic. The long-term impact should continue to be observed. Attention should be paid to HWs for their psychological impact due to the pandemic.Systematic Review Registration: The study protocol was registered with PROSPERO. (shrink)

中国古代的政治文化是在汉代定型的,而汉代的政治文化又可说是由为儒者宗的公羊学大师董仲舒初步建立起来的，汉代公羊家在其中起了奠基作用。汉代公羊家本着对春秋实史与《春秋》文史的沉思，在承继先秦子学与经学资 源的基础上，形成了以原道、托王、宗经为表征的独特哲学思维方式。在此思维运作下，汉代公羊家立足“大一统”、“察名号”、“行权道”、“说灾异”等内容对政治秩序、政治伦理、政治权衡、政治敬畏展开了独特的哲学 思考，构建了由一统政治、名号政治、权道政治、灾异政治合成的独特王道政治哲学，突显了政治秩序性、政治伦理性、政治合法性、政治权变性、政治敬畏性、政治批判性等一系列政治应然性问题，伸张了儒家所反复强调的“ 政治的善”与“善的政治”，在一定程度上超越了政治实然，具有政治理想主义色彩。跳出汉代公羊家对政治的哲学思考范式，对其政治哲学进行反思，在揭示其神秘的思维面纱与难免的时代局限之后，其合理内核也可资鉴当代 政治文明建设。.

Six-month-old infants discriminate between large sets of objects on the basis of numerosity when other extraneous variables are controlled, provided that the sets to be discriminated differ by a large ratio (8 vs. 16 but not 8 vs. 12). The capacities to represent approximate numerosity found in adult animals and humans evidently develop in human infants prior to language and symbolic counting.

Galen Strawson defends his pessimist position with his famous “Basic Argument”. He attempts to prove that no agent can meet the demands for the ultimate moral responsibility. I argue that the Basic Argument is not impressive because it commits to a linear justification framework under which not only the notion of free will and moral responsibility but every notion would inevitably involve a vicious infinite regress. Surprisingly, this point has not been significantly addressed in the literature of Strawson’s Basic Argument. (...) I scaffold my argument against “Basic Argument” by critically reviewing and comparing Frankfurt, Christman and Ekstrom’s approach to autonomy. I show that any approach, which commits to a linear justification framework, would inevitably involve an infinite regress problem. To make his argument more impressive, Strawson will have to show why he commits to a hierarchical justification framework in the Basic Argument in the first place. (shrink)

Chinese mind-body exercises are positively associated with executive function, but their effects on EF, from synthesized evidence using systematic and meta-analytic reviews, have not been conducted. Therefore, the present systematic review with meta-analysis attempted to determine whether CMBEs affect EF and its sub-domains, as well as how exercise, sample, and study characteristics moderate the causal relationship between CMBEs and EF in middle-aged and older adults. Seven electronic databases were searched for relevant studies published from the inception of each database through (...) June 2020. Randomized controlled trials with at least one outcome measure of CMBEs on EF in adults of mean age ≥ 50 years with intact cognition or mild cognitive impairment and with or without chronic diseases were included. A total of 29 studies ultimately were included in this study. The results indicated that CMBEs improved overall EF, as well as its sub-domains of working memory and shifting. The beneficial effects of CMBEs on EF occurred regardless of type, frequency of group classes, session time, total training time, and length of the CMBEs, in addition to that more frequent participation in both group classes and home practice sessions resulted in more beneficial effects. The positive effects of CMBEs on EF were also demonstrated, regardless of participants mean age, sex, and cognitive statuses, health status, as well as training mode and study language. This review thus suggests that CMBEs can be used as an effective method with small to moderate and positive effects in enhancing EF, and that more frequent group classes and home practice sessions may increase these effects. However, certain limitations, including strictly design studies, limited ES samples for specific variables, and possible biased publications, required paying particular attention to, for further exploring the effects of CMBEs on EF.

Previous research on moral dilemmas has mainly focused on decisions made under conditions of probabilistic certainty. We investigated the impact of uncertainty on the preference for action (killing one individual to save five people) and inaction (saving one but allowing five people to die) in moral dilemmas. We reported two experimental studies that varied the framing (gain vs loss), levels of risk (probability of gain and loss) and levels of ambiguity (imprecise probability information) in the choice to save five individuals (...) by sacrificing one. We found that participants preferred actions with uncertainty (risk/ambiguity) over inaction. Specifically, we found that participants preferred actions with precise probability information (risk) over inaction, and they preferred actions with modest or high levels of ambiguity over actions with precise probabilities, especially when moral dilemmas had a loss frame. We also observed commission bias in Study 2. We discussed the implications for research in moral decision-making. (shrink)

Highlighting the implications of entrepreneurship education, this study examines the effects of entrepreneurship education in predicting the entrepreneurial intention of university students. The study also explores the mediating role of opportunity recognition and the moderating role of entrepreneurial learning in this process.

The findings reveal (...) that entrepreneurship education can promote the entrepreneurial intention of students through opportunity recognition. Furthermore, entrepreneurial learning plays a moderating role in the link between entrepreneurship education and opportunity recognition. Implications for the design and delivery of entrepreneurship education are discussed. (shrink)

In this paper, I propose and defend a distinct and novel approach to compensation for risk impositions. I call it the Risk-Pooling System of compensation. This system suggests that when X performs an action that imposes a risk of harm to Y, then X is liable to Y, and is therefore obliged to make an ex ante compensation that is roughly equivalent to the expected cost of potential harm to a social- risk pool. If and when Y suffers harm as (...) a result of the risk imposed by X, they then receive an ex post compensation roughly equivalent to the cost of actual harm suffered. This system of compensation creates a social buffer between the risk imposer – the one who has the duty to pay compensation into the pool – and the victim – the one who has the right to receive compensation from the social pool. I contend that the Risk-Pooling System is an improvement over its alternatives due to its capacity to produce the best social utilities, particularly, in terms of reducing information costs, obtaining optimal deterrence in the society and creating incentives for people to be engaged in social activities.

Teaching seeks to enhance learners’ well-being as well as their educational motivation since both constructs cause advancement in the process of learning and they increase the level of success in the educational cycle. Well-being is a critical requirement inside the academic environment that is considered as the main dimension of individuals’ tendency in the topic of positive psychology research, which is crucial for learning. Besides, as a significant idea in language domain and in order to consider the relation between well-being (...) and motivation, the other concept is arisen in PP, namely resilience that seems to be effective for learners as it deals with the capability to effectively manage difficulties in the past and present time in the learning process. As a result, this study considers the relationship between well-being and motivation; however, it also inspects the mediating role of resilience in this regard. Consequently, this review of literature holds suggestions for researchers, philosophers, and experts searching for better exploration and attention to the functions of resilience as a mediator in the relationship between learners’ motivation and well-being.

Simion and Kelp develop the obligation-based account of trustworthiness as a compelling general account of trustworthiness and then apply this account to various instances of AI. By doing so, they explain in what way any AI can be considered trustworthy, as per the general account. Simion and Kelp identify that any account of trustworthiness that relies on assumptions of agency that are too anthropocentric, such as that being trustworthy, must involve goodwill. I argue that goodwill is a necessary condition for (...) being trustworthy and further suggest a network account of trustworthy AI, which retains the goodwill as the essential requirement for the concept of trustworthiness and meanwhile predicts that current AI can be trustworthy. The alternative account suggests that the focus of trustworthy AI is not merely AI technology, but the whole network of AI involving AI technology, AI designers, AI companies, and other social and legal institutions. A trustworthy AI requires that AI technology is reliable and that other involved agents are trustworthy. (shrink)

Although most existing studies have considered entrepreneurial bricolage as a means to overcome resource constraints in new ventures, few have explored the direct effects of entrepreneurial bricolage on employee creativity, particularly in the context of entrepreneurial internet firms. Drawing from multiple theories, this study proposes a cross-level mediation model for the trickle-down effects of entrepreneurial bricolage and business model innovation on employee creativity. By using a 2-wave longitudinal design, survey data were collected from multiple sources, including 49 leaders and 336 (...) employees from entrepreneurial internet firms in China. Multilevel structural equation modeling was applied to analyze the cross-level mediation model. The results show that both entrepreneurial bricolage and business model innovation failed to significantly and positively direct employee creativity. Furthermore, entrepreneurial bricolage exerted a cross-level influence on employee creativity that was sequentially transmitted through between-level business model innovation and within-level creative self-efficacy. The theoretical and managerial implications of these findings are also discussed. (shrink)

An adaptive fractional-order nonsingular terminal sliding mode controller for a microgyroscope is presented with uncertainties and external disturbances using a fuzzy neural network compensator based on a backstepping technique. First, the dynamic of the microgyroscope is transformed into an analogical cascade system to guarantee the application of a backstepping design. Then, a fractional-order nonsingular terminal sliding mode surface is designed which provides an additional degree of freedom, higher precision, and finite convergence without a singularity problem. The proposed control scheme requires (...) no prior knowledge of the unknown dynamics of the microgyroscope system since the fuzzy neural network is utilized to approximate the upper bound of the lumped uncertainties and adaptive algorithms are derived to allow online adjustment of the unknown system parameters. The chattering phenomenon can be reduced simultaneously by the fuzzy neural network compensator. The stability and finite time convergence of the system can be established by the Lyapunov stability theorem. Finally, simulation results verify the effectiveness of the proposed controller and the comparison of root mean square error between different fractional orders and integer order is given to signify the high precision tracking performance of the proposed control scheme.
