ObjectiveVirtual reality grasping exercise training helps patients participate actively in their recovery and is a critical approach to the rehabilitation of hand dysfunction. This study aimed to explore the effects of active participation and VR grasping on brain function combined with the kinematic information obtained during VR exercises.MethodsThe cerebral oxygenation signals of the prefrontal cortex, the motor cortex, and the occipital cortex were measured by functional near-infrared spectroscopy in 18 young people during the resting state, grasping movements, and VR grasping (...) movements. The EPPlus plug-in was used to collect the hand motion data during simulated interactive grasping. The wavelet amplitude of each cerebral cortex and the wavelet phase coherence of each pair of channels were calculated by wavelet analysis. The total difference in acceleration difference of the hand in the VR grasping movements was calculated to acquire kinematic characteristics. The cortical activation and brain functional connectivity of each brain region were compared and analyzed, and a significant correlation was found between VR grasping movements and brain region activation.ResultsCompared with the resting state, the WA values of LPFC, RPFC, LMC, RMC, and ROC increased during the grasping movements and the VR grasping movements, these changes were significant in LPFC and LMC. The WA values of LMC in the VR grasping movements were significantly higher than those in the grasping movements. The WPCO of the cerebral cortex increased during grasping exercise compared with the resting state. Nevertheless, the number of significant functional connections during VR grasping decreased significantly, and only the WPCO strength between the LPFC and LMC was enhanced. The increased WA of the LPFC, RPFC, LMC, and RMC during VR grasping movements compared with the resting state showed a significant negative correlation with KCs.ConclusionThe VR grasping movements can improve the activation and FC intensity of the ipsilateral brain region, inhibit the FC of the contralateral brain region, and reduce the quantity of brain resources allocated to the task. Thus, ordered grasping exercises can enhance active participation in rehabilitation and help to improve brain function. (shrink)

Based on the institutional theory, this article attempts to examine two consecutive questions regarding the impact of various factors on corporate decision in environmental information disclosure (EID): (1) whether or not to disclose; and (2) the level of disclosure. The relevance of these factors is empirically tested using data collected from publicly listed manufacturing companies from 2006 to 2008 in China. Some interesting findings appear. We find that firms that are state-owned, those that operate in environmentally sensitive industries, those having (...) more industrial peers engaged in EID, and those with better reputation are more likely to disclose environmental information. When it comes to the content of EID, variables that attempt to capture external institutional pressures exhibit either no or weak explanatory power. Only the variable of organizational image and reputation is demonstrated to have a significant impact on both the act and the content of EID. This study provides a snapshot of the dialogues between constituencies in the organizational field and EID development. (shrink)

Despite urgent calls for more research on the integration of business ethics and the meaning of work, to date, there have been few corresponding efforts, and we know surprisingly little about this relationship. In this study, we address this issue by examining when and for whom ethical leadership is more effective in promoting a sense of work meaningfulness among employees, and their subsequent work attitudes. Drawing on the contingency theories of leadership and work meaningfulness literature, we speculate that both employees’ (...) core self-evaluation and perceived organizational support moderate the relationship, but in different ways, and these associations carry over to employees’ subsequent work attitudes in terms of job satisfaction, organizational commitment and turnover intention. We test our hypotheses with two-wave survey data collected from 377 employees. Results indicate that ethical leadership is effective in eliciting work meaningfulness and attitudes for employees higher in CSE or when POS is lower, and ineffective for those lower in CSE or when POS is higher. A supplementary analysis reveals a three-way interaction between ethical leadership, CSE and POS in predicting a sense of work meaningfulness and subsequent work attitudes. Our research cautions that ethical leadership is not a universally positive practice; it can be ineffective or even have a negative impact under some circumstances. (shrink)

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)

The COVID-19 crisis has called into question the utilitarianism-oriented human-wildlife relations and the legitimacy of wildlife protection regime in China. The pandemic has triggered significant, swift, and encompassing changes in policies. Drawing on insights from historical institutionalism, we argue that COVID-19 constitutes a critical juncture in China’s wildlife protection policy.

This study conducted in-depth interviews with 20 students from a university in Wuhan so as to obtain data regarding their collective memory at the early stage of the COVID-19 outbreak and their social imaginaries in the longitudinal dimension of time. Compared with those in other regions, interviewees from Wuhan show more fear and dissatisfaction and think that others find it difficult to empathize with their first-hand experiences. Interviewees from Wuhan are more dependent on the media. However, media use can cause (...) problems related to redundant information and emotional impact. While one is confined to home, he/she is forced to participate in communication with family members and the topic of the body is discussed again from a new angle. Trauma leads to self-reconciliation, as facilitated by the re-examination of and reflection on one’ nomination of and reflection on n family members and the months in the wake of the COVID-19 outbreak. However, having received a collectivist education since childhood and having been guided by the discourse system created by the state media, they have since been able to shape their sense of identity and strengthen their sense of national honor.

In order to explore the mechanism of consumer responses to corporate social responsibility, this paper constructs a research framework including CSR, consumer–company identification, consumer responses, and fit, and tests the framework using a scene-questionnaire survey. Empirical results demonstrate that CSR not only has positive influence on consumer purchase intention, recommend intention, and loyalty directly, but also has indirect positive influence on consumer purchase intention and recommend intention through CCI. The influencing process of CSR on CCI is moderated by fit and (...) the moderating direction is different owing to product types. For the products whose association preference is positive, fit can positively moderate the relationship between CSR and CCI, while for products whose association preference is negative, the moderating role will be negative.

How to mitigate stock price crash risk has become a focus in the theoretical and practical fields. Building on the work of Kim et al., this paper investigates the relation between corporate philanthropy and crash risk under the unique Chinese institutional background. The results show that both state ownership and the 2005 split share reform attenuate the mitigating effect of corporate philanthropy on crash risk. Specifically, the negative relation between corporate philanthropy and crash risk is less pronounced for state-owned enterprises (...) than for non-state-owned enterprises, and it is also less pronounced after firms accomplish the split share reform. Further, this effect is more pronounced for firms with greater financial risks and poorer performance. Our paper contributes to the growing literature on the determinants of stock price crash risk and the economic consequences of corporate philanthropy. It also offers useful guidance to firms that are seeking to reduce stock price crash risk in emerging markets. (shrink)

Grounded in Bandura’s social cognitive theory of moral thought and action, we develop a conceptual model linking supervisors’ perceptions of organizational injustice and abusive supervision with moral disengagement mechanisms acting as the underlying process. Specifically, we elaborate why and how supervisors’ experiences of each type of injustice would trigger their adoption of distinctive moral disengagement mechanisms, which in turn lead to their abusive supervisory conduct. The present conceptual model sheds new light on linking organizational injustice to abusive supervision from a (...) moral perspective. In addition, it also provides important theoretical and managerial implications to our current understanding of why and how abusive supervision happens. (shrink)

In view of the fact that vigorously promoting recycling has become a viable means to promote sustainable development, it is important to better understand the impact of recycling efforts on subsequent resource saving behavior. This research empirically examines the effects of recycling efforts on subsequent resource saving by analyzing the survey data of 356 college students in China. The recycling efforts, environmental self-identity and feeling of pride were measured using existing scales while saving behaviors and recycling cost were measured by (...) developing new scales. Partial least squares structural equation modeling was performed to test the structural relationships among recycling efforts, environmental self-identity, feeling of pride, and saving behaviors. Further, the moderation role of recycling cost was tested. The results showed that saving behaviors could be classified into two types based on their costliness; recycling efforts have a positive effect on costless saving behaviors, while having a negative effect on costly saving behaviors; both the positive and negative effect of recycling efforts on resource saving is mediated by pride feeling and environmental self-identity; and recycling cost negatively moderates the effects of recycling efforts on pride feeling. We discuss the theoretical and managerial implications of the findings. (shrink)

Immersive 360-degree video has become a new learning resource because of its immersive sensory experience. This study examined the effects of textual and visual cues on learning and attention in immersive 360-degree video by using eye-tracking equipment integrated in a virtual reality head-mounted display. Participants were randomly assigned to one of four conditions: no cues, textual cues in the initial field of view, textual cues outside the initial FOV, and textual cues outside the initial FOV + visual cues. The results (...) showed that the cues helped learners achieve better learning outcomes and spend more time focusing on the areas with cues. In addition, the study found a serious imbalance in the distribution of learners’ attention in each region of the video. The attention directed to textual cues in the initial FOV is much higher than the attention directed to textual cues outside the initial FOV. Adding visual cues can effectively direct attention to textual cues outside the initial FOV and alleviate the imbalance of attention distribution. Consequently, adding cues to immersive 360-degree video can be an appropriate approach to promote learning and guide attention in immersive 360-degree video learning environments. This study provided new insights into the design and development of immersive 360-degree video instructional resources. (shrink)

In this study, we investigated the integration between neuroscience and entrepreneurship. First, we explored the concept of neuroentrepreneurship and the investigation of neuroentrepreneurship using scientific research methods. Second, we constructed a road map for entrepreneurial researchers interested in conducting neuroentrepreneurship-related research. This is an emerging research area; therefore, to more clearly analyze the dynamics of the research trends, we used a bibliometric method to capture patterns in current publications on subjects related to neuroentrepreneurship, examining papers published between 1999 and 2021 (...) using the keywords “neuroscience” and “entrepreneurship” or “neuroentrepreneurship.” To identify the keywords, we used two academic databases—the Social Science Citation Index and Science Citation Index—accessed through the Web of Science website. The three keywords were identified from studies integrating neuroscience with entrepreneurship. After carefully reviewing the research papers, we identified neuroentrepreneurship as a novel research area. The outcomes of this study provide a guide for describing the theoretical connection between neuroscience and entrepreneurship. In the future, this field of study should be empirically investigated.

The COVID-19 pandemic has created enormous challenges for organizations and employees. Due to the effectiveness of idiosyncratic deals in management practices, more and more organizations use this human resource management tool to address the challenges posed by the COVID-19 pandemic. However, whether there are potential risks or negative effects of i-deals in the COVID-19 pandemic environment is not very clear. Drawing upon social cognitive theory, we proposed that i-deals may foment focal employees’ unethical behavior by triggering their hubristic pride, and (...) such process may be moderated by their trait of grandiose narcissism. We conducted a survey during the COVID-19 outbreak and tested our hypotheses with 492 samples from Shandong Province, China. Consistent with predictions, we found a positive relationship between i-deals and hubristic pride, which, in turn, increased their unethical behavior. And the relationship between i-deals and unethical behavior was mediated by hubristic pride. Furthermore, grandiose narcissism strengthened the positive relationship between i-deals and hubristic pride, as well as the indirect effect of i-deals on unethical behavior via hubristic pride. Our findings contributed to the literature on i-deals and provided guidance for organizations to address the challenges posed by the COVID-19 pandemic. (shrink)

This co-edited volume compares Chinese and Western experiences of engineering, technology, and development. In doing so, it builds a bridge between the East and West and advances a dialogue in the philosophy of engineering.

In the context of China’s supply-side structural reform and the concept of green development, we introduce the energy and environmental factors into the analytical framework of the total factor productivity of the logistics industry and use the Global Malmquist–Luenberger index method to analyze the evolution trend and heterogeneity of green TFP in the logistics industry of 30 provinces in China from 2003 to 2017. The results show that, firstly, the green TFP and traditional TFP of China’s logistics industry are both (...) on the rise and the absence of energy and environmental factors will lead to the overestimation of TFP of the logistics industry. Whether it is green TFP or traditional TFP, the main source of its growth is technical progress. Secondly, there is obvious regional heterogeneity in green TFP of logistics industry. Under the three regional division standards, the average annual growth rate of green TFP is from high to low in the order of eastern, western, and central regions. Under the eight regional classification standards, the eastern coastal economic zone, the southern coastal zone, the northern coastal zone, the northeast region, the middle reaches of the Yellow River, the southwest region, the middle reaches of the Yangtze River, and the northwest region are in order from high to low. Thirdly, there is obvious interprovincial heterogeneity in green TFP of the logistics industry. The highest growth rate of green TFP is in Zhejiang, followed by Jiangsu and Guangdong, and the slowest growth rate is in Chongqing. The technical progress of logistics industry in most provinces contributes more to the growth of green TFP. Fourthly, the differences of green TFP in the three regions of the east, center, and west are shrinking, which may be σ convergence, but the differences among the three regions are expanding. Compared with the existing literature, this paper applies the measurement framework of green TFP to China’s logistics industry and investigates the regional and provincial heterogeneity of green TFP in logistics industry. The conclusions are significant to understand and grasp the heterogeneity of green TFP growth in China’s logistics industry under environmental constraints and how to promote the development of green logistics in China.

PurposeThis study aims to investigate the mediational path of the influence of cultural orientation on the COVID-19 pandemic outcome at the national level and find out whether some culture-related factors can have a moderating effect on the influence of culture.MethodologyCultural dimension theory of Hofstede is used to quantify the degree of each dimension of culture orientation. The cross-section regression model is adopted to test if culture orientations affect the pandemic outcome, controlling for democracy, economy, education, population, age, and time. Then, (...) a mediational analysis is conducted to examine if policy response is the mediator that culture makes an impact on the pandemic outcome. Finally, a moderation analysis is carried out to determine how each control variable has moderated the influence.FindingsThe cross-section regression results showed that culture orientation influences the outcome of the COVID-19 pandemic at the 99% confidence level and that among the six cultural dimensions, collectivism-individualism has the most significant impact. It has also been found that policy response is the mediator of cultural influence, and culture-related factors can moderate the influence.ContributionThe contribution of this research lies in developing the assertion that culture influences pandemic outcomes. Our findings indicate that collectivism-individualism culture orientation affects the effectiveness of epidemic controls the most among the six culture dimensions. Additionally, our research is the first to study the mediating effect of policy responses and the moderating effect of culture-related factors on the influence of cultural orientation on the pandemic outcome.

Aging has become a serious social problem in China. Traditional informal long-term care is hard to sustain because of the reduction in family size and elders’ children migration to big cities. The institution offering services for the disabled elders has been a tendency. There exists a strange phenomenon: some nursing homes are difficult to enter for most disabled elders, while the other ones must search for elders to maintain operation. Therefore, for the evaluation of nursing homes, two problems should be (...) considered: selecting suitable nursing homes for disabled elders; obtaining the key factors influencing the selection of elders and helping nursing homes improve their services based on the key factors. First, we propose a new DEMATEL method for PLTSs to solve the second problem. Then, we present a novel PROMETHEE method to rank the alternatives and make a sensitivity analysis for criteria. Finally, we illustrate our proposed methods to an evaluation problem in Zhenjiang City by a case study. Based on the case study, we can obtain that our proposed methods are effective and practicable.

Among the beliefs related to teaching work, self-efficacy stands out and encourage innovation across the global education systems. Specifically, the lack of interest among instructors in introducing innovative techniques in physical education is a concern across China. Therefore, this study intends to investigate the role of cognitive indicators of innovation in physical education across China. This study opted for quantitative techniques, including using a structured questionnaire to collect data from targeted respondents through the survey techniques. Moreover, 800 questionnaires were circulated, (...) and as a result, 420 usable responses were attained, making the overall response rate stand at 40%. The results indicate that the above-stated cognitive factors, along with self-efficacy, have a positive role in causing innovation across the physical education exchequer of China. Likewise, self-efficacy played the mediating role between cognitive indicators and innovation in physical education in China. The study has notable theoretical and practical implications for the policymakers in terms of introducing policies that could help increase the cognitive state of educationists, which in turn possibly will help make them pursue innovation within the education system of China.

Third-party fairness maintenance could win some reputational benefits, and it includes two methods: punishment and compensation. We predicted that the third parties' preference between punishment and compensation are affected by whether they are free to choose between the two methods, and the affection could be interpreted through reputational benefits. The present study includes two sections. In Study 1, the participants acted as fourth parties who were asked to rate the reputations of the third parties who had chosen different response methods (...) to an unfair result of the dictator game. The results showed that there was no reputational difference between the two methods when third parties were not free to choose, but the reputation of compensation was better when third parties were free to choose. In Study 2, the participants acted as third parties. The participants were asked to choose a method to respond to an unfair result of the dictator game. There were two reputational contexts: secret and open. The results showed that when third parties were not free to choose, they had no preference between the two methods under the two reputational contexts, but when third parties were free to choose freely, they prefer punishment under the secret context but prefer compensation under the open context. This study systematically reveals a reputational interaction between fourth and third parties, and verifies the affection of reputational benefits on the third parties' preference between punishment and compensation.

The isolation requirements of the coronavirus epidemic and the intuitive display advantages of live-streaming have led to an increasing number of retailers shifting to social live-streaming platforms and e-commerce live-streaming platforms to promote and sell their products in real time. However, the provision of live-streaming services will also incur high live-streaming effort costs. In this paper, we develop two decision models for retailers to sell goods through a single online shop and both online shop and live-streaming room; we also present (...) the optimal decisions of pricing and live-streaming efforts. Furthermore, we identify the profitability conditions for retailers to determine when to provide live-streaming services. In addition, we examine the impact of the provision of live-streaming services on the optimal price and live-streaming effort. We obtain three findings. First, there is a unique optimal decision on the price and live-streaming effort under certain conditions. Second, when the effect coefficient of the live-streaming room reaches a certain threshold, there are enough customers who enter the live-streaming room to watch and buy and it is profitable for retailers to provide live-streaming service. Finally, the optimal price and live-streaming effort increase with the increase in average return loss, the effect coefficient of live-streaming effort, and the extra return rate and decrease with the increase in the proportion of customers who choose to buy in the online shop and the price discount coefficient in the live-streaming room.

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.

This article analyzes Xueji and discusses some of the myths and facts in Western perceptions of Chinese educational practice. It also looks at the similarities and contrasts between Eastern and Western conceptions of teaching and learning. A careful study of Xueji will help in understanding some common Western misunderstandings and misperceptions of Chinese pedagogic practices, in particular, the views that Chinese educational practices and ideas are authoritarian, encourage obedience to authority over individual inquiry, promote memorization over comprehension, and are non-individualized (...) to the point of encouraging uniformity over diversity. A better understanding of the classical Chinese approach to learning and teaching will foster a deeper understanding of the nature of pedagogic practices. Such an understanding will enable us to make a better assessment of the similarities and differences between Chinese and Western conceptions of learning and teaching with a view to sharing ideas from both cultural and philosophical perspectives. Throughout the discussion, this article will seek insights for teaching and learning today in a global context. (shrink)

Individualism is not only a Western tradition. In the Zhuangzi we can also identify some elements which may be appropriately attributed to “individualism.” However, due to its particular cultural and philosophical background, Zhuangzian individualism has unique characteristics, which distinguish it from the variety of other individualist thoughts that have emerged in the West. Zhuangzi has a dynamic and open view on individual “self,” considering individuals as changing and unique beings rather than fixed and interchangeable “atoms”; he sets the unlimited Dao (...) as the ultimate source for individuals to conform to, thus releasing individual mind into a realm of infinite openness and freedom. The Zhuangzian individualism is “inward” rather than “outward,” concentrating on individual spirit rather than material interests and rights in social reality. The individualism in the Zhuangzi provides a spiritual space for the development of individuality in ancient China. It also provides an alternative understanding of individual as an existence.
