The problem of adaptive finite-time fault-tolerant control and output constraints for a class of uncertain nonlinear half-vehicle active suspension systems are investigated in this work. Markovian variables are used to denote in terms of different random actuators failures. In adaptive backstepping design procedure, barrier Lyapunov functions are adopted to constrain vertical motion and pitch motion to suppress the vibrations. Unknown functions and coefficients are approximated by the neural network. Assisted by the stochastic practical finite-time theory and FTC theory, the proposed (...) controller can ensure systems achieve stability in a finite time. Meanwhile, displacement and pitch angle in systems would not violate their maximum values, which imply both ride comfort and safety have been enhanced. In addition, all the signals in the closed-loop systems can be guaranteed to be semiglobal finite-time stable in probability. The simulation results illustrate the validity of the established scheme.

This article explores impact investing within the renewable energy sector. Drawing on ethical decision making and sensemaking, this article contributes to an enhanced understanding of the complex ethical sensemaking process of impact investors when facing plausible situations in a world of contested truths. Addressing the ethical tensions faced by impact investors with mixed motives, this study investigates the way decision makers use context-specific reasons to make sense of and shape the renewable energy investment process. This represents an initial attempt to (...) understand ethical sensemaking in impact investing made within the renewable energy sector using a multi-stakeholder approach. Our findings show that prosocial, personal, reputational, and economic motives are the main drivers of REI, with prosocial and personal motives being value-based, and reputational and economic motives being evidence-based. We find three different modes of ethical sensemaking, allowing for the construction of the four motives noted above. These motives are based on the context-specific reasons of impact investing decision makers in the RE sector. This article contributes to the academic discourse on ethical sensemaking with some key processes involved in ethical decision making, and a better understanding of the underlying motivations of impact investing in the RE sector.

MPZL3 is a nuclear‐encoded, mitochondrially localized, immunoglobulin‐like V‐type protein that functions as a key regulator of epithelial cell differentiation, lipid metabolism, ROS production, glycemic control, and energy expenditure. Recently, MPZL3 has surfaced as an important modulator of sebaceous gland function and of hair follicle cycling, an organ transformation process that is also governed by peripheral clock gene activity and PPARγ. Given the phenotype similarities and differences between Mpzl3 and Pparγ knockout mice, we propose that MPZL3 serves as a signaling hub (...) that is regulated by core clock gene products and/or PPARγ to translate signals from these nuclear transcription factors to the mitochondria to modulate circadian and metabolic regulation. Conservation between murine and human MPZL3 suggests that human MPZL3 may have similarly complex functions in health and disease. We summarize current knowledge and discuss future directions to elucidate the full spectrum of MPZL3 functions in mammalian physiology. (shrink)

Despite the rising interest in environmental strategies, few studies have examined how managerial cognition of such strategies influences actual innovation capability development. Taking a managerial cognition perspective, this study investigates how managers’ perceptions of institutional pressures relate to their focus on proactive environmental strategy, which in turn affects firms’ realized innovation capability. The findings from a primary survey and three secondary datasets of publicly listed companies in China reveal that managers’ perceived business and social pressures are positively associated with their (...) focus on proactive environmental strategy, which consequently fosters innovation capability development. Moreover, state ownership and government administrative control weaken the impact of managerial focus on proactive environmental strategy on innovation capability. These findings have important implications for how managerial cognition supports environmental strategy and organizational capability building under the influence of institutional pressures and government intervention.

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.

Although the trickle-down effect of ethical leadership has been documented in the literature, its underlying mechanism still remains largely unclear. To address this gap, we develop a cross-level dual-process model to explain how the effect occurs. Drawing on social learning theory, we hypothesize that the ethical leadership of high-level managers could cascade to middle-level supervisors via its impact on middle-level supervisors’ two ethical expectations. Using a sample of 69 middle-level supervisors and 381 subordinates across 69 sub-branches from a large banking (...) firm in China, we found that middle-level supervisors’ ethical efficacy expectation and unethical behavior–punishment expectation accounted for the trickle-down effect. The explanatory role of middle-level supervisors’ ethical behavior–reward expectation, however, was not supported. The theoretical and practical implications are discussed. (shrink)

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

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)

Objective: Pulmonary complications could badly affect the recovery of neurological function and neurological prognosis of neurological critically ill patients. This study evaluated the effect of high-flow nasal cannula therapy on decreasing pulmonary complications in neurologically critically ill patients.Patients and Methods: The patients admitted to the intensive care unit with serious neurological disease and receiving oxygen therapy were retrospectively reviewed. Patients were divided into the HFNC group and the conventional oxygen therapy group. We analyzed the data within these two groups, including (...) patients’ baseline data, short-term outcomes of respiratory complications, general outcomes including hospital stay, ICU stay and mortality, and neurological functions. To analyze the relevant factors, we performed multivariable logistic regression analysis.Results: A total of 283 patients met the criteria, including 164 cases in the HFNC group and 119 cases in the COT group. The HFNC group had remarkably less mechanical ventilation requirement with lower phlegm viscosity. Even more, ICU stay and total hospital stay were significantly shortened in the HNFC group.Conclusion: HFNC decreased pulmonary complications in neurologically critically ill patients and improved recovery of neurological function and neurological prognosis.

With the quickly rising popularity of smartphone among adolescents over the past decade, studies have begun to investigate the relationship between smartphone addiction and Eysenck's personality traits. Despite numerous studies on this topic, however, findings have been mixed and there is a lack of consensus regarding this relationship. Thus, this meta-analysis aimed to explore the relationship between smartphone addiction and Eysenck's personality traits in Chinese adolescents, as well as its possible moderators. Through literature search and screening, 33 studies were included, (...) comprising 79 independent effect sizes with a total of 17, 737 subjects. A random effects model was selected, and it was found that smartphone addiction was positively associated with psychoticism and neuroticism, but not significantly associated with extroversion. The moderating effect test showed that sex and year of study publication had significant influences on the relationship between smartphone addiction and psychoticism, and the year of study publication had a significant influence on the relationship between smartphone addiction and neuroticism. This study is the first meta-analysis on the relationship between smartphone addiction and Eysenck's personality traits among adolescents in China, and the results have helped to clarify the controversy of previous studies regarding this relationship.

This study explores the online education action for defeating COVID-19 in China from the perspectives of the system, mechanism and mode. In particular, the policy development of online education in China during the epidemic includes the education informatization policy, the online education system, and the online education mechanism in China. The online education and teaching mode during the epidemic involve the synchronous live class-based teaching mode, asynchronous recording and broadcasting teaching mode, online flipped classroom teaching mode, and online tutoring-based teaching (...) mode. Both characteristics and trends of online education in China during the epidemic have been explored in this study. In addition, the problems, discussions and remarks are also offered. (shrink)

This study examines the influence of underwriter–auditor relationship on pre-initial public offering earnings management. Using a sample of Chinese to-be-listed firms, we find that a close UAR, as reflected in repeated collaborations between an underwriter and an audit firm in IPOs, is positively associated with pre-IPO earnings management. This association is more pronounced for firms with politically connected auditors/underwriters, firms with less reputable auditors/underwriters, firms located in provinces with weak legal environment, firms to-be-listed on boards with lax listing requirements, and (...) firms whose auditors are with low industry specialization, and legal liability exposures. We provide further evidence that UAR is associated with greater likelihood of irregular activities in post-IPO period and poorer post-IPO financial performance. To the extent that we control for alternative explanations and potential endogeneity, our results suggest that the collusion incentive is likely to drive repeated collaborations between underwriters and auditors in the Chinese IPO market. Our findings provide interesting implications for auditors, investors, and regulators seeking to understand the Chinese IPO market. (shrink)

Analytic philosophy has been developing in China for over a century, and philosophers shaped by the analytic tradition have grown into an important philosophical community in China. The views of contemporary analytic philosophers in China on central philosophical issues and their similarities and differences with analytic philosophers in English-speaking countries have not been systematically investigated. Bourget and Chalmers have conducted two large-scale online questionnaire surveys on analytic philosophers in English-speaking countries. Inspired by their studies, a survey on analytic philosophers in (...) China was performed. It is found that philosophers in China had no agreement on most issues. According to the comparative analysis with the results of Bourget and Chalmers’ second survey, there were significant differences in views as well as thinking styles between analytic philosophers in China and English-speaking countries. And these differences may be partially explained by cultural factors and academic environments. (shrink)

Pinyin is a phonological encoding system used to spell modern Chinese Mandarin due to the phonological opacity of Chinese characters. The present study examined the role of Pinyin spelling in the reading abilities of adolescents learning Chinese as a foreign language. A total of 158 Indonesian senior primary students were tested on Pinyin spelling, character production, listening comprehension, depth of vocabulary knowledge, and reading comprehension. Pinyin spelling skills were assessed by two measures, Pinyin Dictation and Pinyin Tagging. Path analysis revealed (...) that even after controlling for the effect of character production, Pinyin dictation performance influenced reading comprehension through the mediating effect of listening comprehension and the depth of vocabulary knowledge, and Pinyin tagging performance also influenced reading comprehension through the mediating effect of the depth of vocabulary knowledge. The results highlight the importance of Pinyin skills for Chinese reading abilities of CFL learners. As a reliable and explicit indicator of specifying Chinese phonological representations and processing, Pinyin spelling has a long-term and multifaceted influence on higher-level CFL abilities.

The Myelin Regulator Factor (MYRF) is a master regulator governing myelin formation and maintenance in the central nervous system. The conservation of MYRF across metazoans and its broad tissue expression suggest it has functions extending beyond the well‐established role in myelination. Loss of MYRF results in developmental lethality in both invertebrates and vertebrates, andMYRFhaploinsufficiency in humans causesMYRF‐related Cardiac Urogenital Syndrome, underscoring its importance in animal development; however, these mechanisms are largely unexplored. MYRF, an unconventional transcription factor, begins embedded in the (...) membrane and undergoes intramolecular chaperone mediated trimerization, which triggers self‐cleavage, allowing its N‐terminal segment with an Ig‐fold DNA‐binding domain to enter the nucleus for transcriptional regulation. Recent research suggests developmental regulation of cleavage, yet the mechanisms remain enigmatic. While some parts of MYRF's structure have been elucidated, others remain obscure, leaving questions about how these motifs are linked to its intricate processing and function. (shrink)

The unprecedented public panic caused by COVID-19 will affect the recovery of tourism, especially the theme parks, which are generally crowded due to high visitor volume. The purpose of this study is to discuss the effect of the COVID-19 on the theme park industry. This study aims to predict recommendation intentions of theme park visitors by exploring the complicated mechanism derived from the fear of COVID-19. This study uses a quantitative research method, and SPSS 20.0 and AMOS 22.0 were used (...) for data analysis. An online survey was conducted with 420 Chinese respondents who visited Shanghai Disneyland after its reopening. The study explored the relationship between Fear of COVID-19, perceived risk, participation, service experience, and revisit intention. Results indicated the perceived risk of theme park visitors will not directly ruin their recommendation intention. Visitors’ fear of COVID-19 enhanced their perceived risk, reduced their desire for active participation and impaired their service experience, which consequently affected their recommendation intention. We provide theoretical and managerial implications. (shrink)

BackgroundIndividuals who use methamphetamine for a long period of time may experience decreased inhibition and increased impulsivity. In order to reduce impulsivity or improve inhibitory control ability, high-frequency repetitive transcranial magnetic stimulation has attracted much attention of researchers. Recent studies on addiction have shown that rTMS can stimulate different brain regions to produce different therapeutic effects. Recent work also suggests that HF-rTMS over right dorsolateral prefrontal cortex does not affect the impulsivity of patients with alcohol use disorder; while HF-rTMS over (...) left DLPFC could improve the impulsivity of patients with alcohol use disorder and cigarette smokers. However, it should be noted that empirical studies applying HF-rTMS over left DLPFC of patients with MA use disorders are still lacking.MethodsTwenty-nine patients with MAUD underwent five sessions of HF-rTMS on the left DLPFC per week for 4 consecutive weeks. The cue-induced craving and stop-signal and NoGo task were assessed pre-rTMS and post-rTMS. In addition, 29 healthy controls were recruited. There was no rTMS intervention for the controls, the performance of the stop-signal and NoGo task was evaluated on them.ResultsIn total, HF-rTMS of the left DLPFC significantly decreased MA-dependent patients’ cue-induced craving and stop-signal reaction time. For SSRT, the pre-test of experimental group was significantly higher than the score of control group. In the experimental group, the pre-test score was significantly higher than the post-test score. For Go and stop-signal delay, the pre-test scores of the experimental group was significantly lower than the scores of the control group. No significant difference was found between the pre-test and the post-test scores of the experimental group.ConclusionAdd-on HF-rTMS of left DLPFC may be an effective intervention for reducing impulsivity and cue-induced craving of patients with MAUD. Future research with a control group of MAUD that does not undergo the treatment is needed to confirm the effectiveness. (shrink)

Community detection is one of the key research directions in complex network studies. We propose a community detection algorithm based on a density peak clustering model and multiple attribute decision-making strategy, TOPSIS. First, the two-dimensional dataset, which is transformed from the network by taking the density and distance as the attributes of nodes, is clustered by using the DBSCAN algorithm, and outliers are determined and taken as the key nodes. Then, the initial community frameworks are formed and expanded by adding (...) the most similar node of the community as its new member. In this process, we use TOPSIS to cohesively integrate four kinds of similarities to calculate an index, and use it as a criterion to select the most similar node. Then, we allocate the nonkey nodes that are not covered in the expanded communities. Finally, some communities are merged to obtain a stable partition in two ways. This paper designs some experiments for the algorithm on some real networks and some synthetic networks, and the proposed method is compared with some popular algorithms. The experimental results testify for the effectiveness and show the accuracy of our algorithm. (shrink)

In this article, we introduce a hierarchy on the class of non-archimedean Polish groups that admit a compatible complete left-invariant metric. We denote this hierarchy by $\alpha $ -CLI and L- $\alpha $ -CLI where $\alpha $ is a countable ordinal. We establish three results: (1) G is $0$ -CLI iff $G=\{1_G\}$ ; (2) G is $1$ -CLI iff G admits a compatible complete two-sided invariant metric; and (3) G is L- $\alpha $ -CLI iff G is locally $\alpha $ (...) -CLI, i.e., G contains an open subgroup that is $\alpha $ -CLI. Subsequently, we show this hierarchy is proper by constructing non-archimedean CLI Polish groups $G_\alpha $ and $H_\alpha $ for $\alpha <\omega _1$, such that: (1) $H_\alpha $ is $\alpha $ -CLI but not L- $\beta $ -CLI for $\beta <\alpha $ ; and (2) $G_\alpha $ is $(\alpha +1)$ -CLI but not L- $\alpha $ -CLI.

Over the last 50 years, there has been significant development of qualitative research and related methods in healthcare. Theoretical frameworks support researchers in selecting appropriate research approaches, procedures and analytical tools. However, the implications of the choice of theory are sparsely elucidated. Based on a text excerpt from a public debate article, the study aimed to show how different theory‐inspired analytical perspectives produced varied understandings of the same text. The study presented three subanalyses inspired by Bourdieu's sociological theory, Lazarus and (...) Folkman's psychological theory and utilitarian ethics, respectively. The analyses showed that by using different theoretical analytical perspectives in inductive processes, an immediate interpretation of the text was not obvious. It became possible to spot the underlying meta‐theoretical assumptions, as the interpretations were not taken for granted or indisputable. Our analyses suggest that different theoretical lenses lead to different interpretations of the same empirical material, recognising the existence of multiple truths or realities. Thus, utilising a theoretical perspective in inductive analyses can enhance transparency and rigour because the analytical optics are made explicit to the reader. This allows the reader to follow the analysis processes and comprehend from which theoretical starting point a truth arises. (shrink)

Time-varying formation-containment problems for a second-order multiagent system are studied via pulse-modulated intermittent control in this paper. A distributed control framework utilizing the neighbors’ positions and velocities is designed so that leaders in the multiagent system form a formation, and followers move to the convex hull formed by each leader. Different from the traditional formation-containment problems, this paper applies the PMIC framework, which is more common and more in line with the actual control scenarios. Based on the knowledge of matrix (...) theory, algebraic graph theory, and stability theory, some sufficient conditions are given for the time-varying formation-containment problem of the second-order multiagent system. Some numerical simulations are proposed to verify the effectiveness of the results presented in this paper. (shrink)

The present research explored how foreign language listening anxiety affected Chinese university students' English listening test performance and how proficiency and gender mediated the effects of FLLA on the latter. Two different populations from two universities in China answered the 20-item Foreign Language Listening Anxiety Scale as well as a demographic questionnaire and took an English listening test. Analyses of the collected data revealed the following major findings: Five latent factors underlay the FLLAS, when working alone, FLLA significantly negatively predicted (...) students' English listening test performance, and when working with proficiency and gender, English proficiency level, gender and FLLAS2 significantly predicted students' English listening test performance. These findings confirm the negative effects of FLLA on students' English listening test performance. They also indicate that English proficiency and gender mediate FLLA's effects on the latter, with English proficiency not only directly but also indirectly affecting the latter. (shrink)

While past studies have enriched our understanding of the impact of returnee executives on firm market strategy and outcomes, we know relatively little about the relationship between returnee executives and firm nonmarket strategies. Grounded in upper echelons theory, this study explores the relationship between returnee executives and corporate philanthropy, the latter of which is an important nonmarket strategy in emerging economies such as China. Using data on publicly listed Chinese companies from 2010 to 2017, we find that the proportion of (...) returnee executives is negative related to corporate philanthropy. We also find that this negative relationship is strengthened by executive ownership, but weakened by corporate prominence and political connections. Our study makes important theoretical contributions to strategic leadership research, upper echelons theory, and the literature of corporate philanthropy.

The discourse on Confucianism during the early Republican Era has predominantly revolved around debates among intellectuals and societal elites. This study shifts the focus to the grassroots reconstruction of Confucianism undertaken by Wang Fengyi, a peasant theorist, practitioner, and educator who played a pivotal role in the “the Way of the Virtuous” (shanrendao) movement in Northeastern China during the late nineteenth and early twentieth centuries. Wang was a staunch advocator for the education and literacy of peasant women, who occupied the (...) lowest rungs of society. This chapter delves into his moral philosophy of education, which centers around the idea that women’s literacy is a moral issue. Furthermore, this chapter examines the convergence between Wang Fengyi’s gendered moral philosophy of education and the wartime educational ideology and mobilization efforts of the Japanese colonial administration in Manchukuo. This alignment was conducive – during the last years of Wang’s life – to the co-optation of his initiatives by the colonial administration, in their efforts to reach the impoverished underclass in Manchukuo.

Most Chinese words are compounds formed through the combination of meaningful characters. Yet, due to compositional complexity, it is poorly understood how this combinatorial process affects the access to the whole‐word meaning. In the present study, we turned to the recent development in compositional distributional semantics, and employed a deep neural network to learn the less‐than‐systematic relationship between the constituent characters and the compound words. Based on the compositional representations derived from the computational model, we investigated the combinatorial process in (...) terms of the degree of overlap between the compositional and the lexicalized representations as well as the degree of distinctness of the compositional representation. Analyses of lexical decision and eye‐tracking data revealed the effects of both compositional attributes over and above the effects of constituent character features and compound features, indicating an active engagement of the combinatorial process in compound processing. Moreover, with the increase of compound frequency, and thus the increased likelihood that the holistic route prevails, these compositional effects appeared to be dampened. These findings, therefore, provided a computational characterization for the dual‐route framework, which sheds light on the universal process of compound comprehension across different languages.

Epidemiological studies have confirmed that long-term exposure to road traffic noise can cause cardiovascular diseases, and when noise exposure reaches a certain level, the risk of related CDs significantly increases. Currently, a large number of Chinese residents are exposed to high noise exposure, which could greatly increase the risk of cardiovascular disease. On the other hand, relevant studies have found that people with high noise sensitivity are more susceptible to noise. And it is necessary to pay more attention to the (...) high noise-sensitive people. This study investigated the acute physiological effect of different noise-sensitive groups by indoor-level noise stimulus experiments under laboratory conditions, by observing heart rate variability indicators, including standard deviation of NN intervals, low frequency/high frequency, and heart rate. The results showed that there was no significant difference in HRV between the high-sensitive group and the low-sensitive group at the physiological baseline and the different stimulating noise levels. Then, based on the theory of cumulative effect of noise proposed by WHO Regional Office for Europe, non-significant but observable differences between groups were further discussed. By analyzing differences of the variation trends and the within-group significant changes of SDNN and HR between the two groups, the results tended to show that the high-sensitive group is more affected by road traffic noise. In addition, the values of SDNN and HR showed observable between-group differences at 55 dB and 65 dB which corresponding to the SPL associated with a significantly increased risk of cardiovascular disease concerned by epidemiological studies. According to the cumulative effect theory, these differences in HRV caused by short-term noise stimulation may have the potential to produce physiological response and lead to between-groups differences in prevalence after long-term recurrent effect, and deserve attention and further research.

With the rapid development of artificial intelligence technology, multitasking textual translation has attracted more and more attention. Especially after the application of deep learning technology, the performance of multitask translation text detection and recognition has been greatly improved. However, because multitasking contains the interference problem faced by the translated text, there is a big gap between recognition performance and actual application requirements. Aiming at multitasking and translation text detection, this paper proposes a text localization method based on multichannel multiscale detection (...) of the largest stable extreme value region and cascade filtering. This paper selects the appropriate color channel and scale to extract the maximum stable extreme value area as the character candidate area and designs a cascaded filter from coarse to fine to remove false detections. The coarse filter is based on some simple morphological features and stroke width features, and the fine filter is trained by a two-recognition convolutional neural network. The remaining character candidate regions are merged into horizontal or multidirectional character strings through the graph model. The experimental results on the text data set prove the effectiveness of the improved deep learning network character model and the feasibility of the textual implication translation analysis method based on this model. Among them, the text contains translation character recognition results prove that the model has good description ability. The characteristics of the model determine that this method is not sensitive to the scale of the sliding window, so it performs better than the existing typical methods in retrieval tasks. (shrink)

Road link speed is one of the important indicators for traffic states. In order to incorporate the spatiotemporal dynamics and correlation characteristics of road links into speed prediction, this paper proposes a method based on LDA and GCN. First, we construct a trajectory dataset from map-matched GPS location data of taxis. Then, we use the LDA algorithm to extract the semantic function vectors of urban zones and quantify the spatial dynamic characteristics of road links based on taxi trajectories. Finally, we (...) add semantic function vectors to the dataset and train a graph convolutional network to learn the spatial and temporal dependencies of road links. The learned model is used to predict the future speed of road links. The proposed method is compared with six baseline models on the same dataset generated by GPS equipped on taxis in Shenzhen, China, and the results show that our method has better prediction performance when semantic zoning information is added. Both composite and single-valued semantic zoning information can improve the performance of graph convolutional networks by 6.46% and 8.35%, respectively, while the baseline machine learning models work only for single-valued semantic zoning information on the experimental dataset.

The enterprise network is of great significance in explaining the risk-taking of individual firm. However, some unobservable networks hidden in different firms have long been neglected. Using the text data of the annual reports of China’s listed firms from 2007 to 2018, this paper adopts a textual analysis method to capture the managers’ perceptions of pressure, and build a special kind of hidden inter-firm networks, that is, the perceived competition networks of managers. In addition, this paper discusses the impact of (...) network characteristics on corporate risk-taking behavior. Empirically, there is a positive association between competition strength and corporate risk-taking, as well as the density of perceived competition network. Furthermore, this paper explores the risk-taking behaviors of peer firms in focal firm’s perceived competition network, and finds that the improvement of peer firms’ risk-taking significantly increases the risk bearing level of focal firm, that is, the positive spillover effect of risk-taking behavior among firms in perceived competition networks. Moreover, managers’ personal traits significantly moderate the impact of network characteristics on corporate risk-taking, which is mainly reflected in younger and male managers. Our findings can enrich the literature on social interactions and corporate behaviors, and help firms to improve their understanding of perceptible peer firms. (shrink)

This study explorers whether the relative impacts of brand identification and identification with other users of brand pages on brand loyalty vary according to consumers’ regulatory focus. By integrating social identification theory with regulatory focus theory, this study adopts a dual identification framework to compare the differential impacts of promotion regulatory fit and prevention regulatory fit on brand loyalty. Besides, the moderating effects of product type on the relationship between promotion/prevention regulatory fit and brand loyalty are further investigated. Finally, this (...) study uses different combinations of information technology affordances in order to examine their influences on each identification target. The current study adopts a qualitative methodology and involved conducting semi-structured interviews with 27 brand page users in regard to IT affordances and their subdimensions.

The results support our hypotheses and confirm the differential effects of promotion and prevention regulatory fit on brand loyalty. Theoretically, our study enhances our understanding of the relative effect of dual identification on brand loyalty on social media. Practically, our study delivers insights for companies into how social media brand pages can be used as a strategic tool to achieve brand values. (shrink)

With the improvement of citizens’ risk perception ability and environmental protection awareness, social conflicts caused by environmental problems in large-scale construction projects are becoming more and more frequent. Traditional social risk prevention management has some defects in obtaining risk data, such as limited coverage, poor availability, and insufficient timeliness, which makes it impossible to realize effective early warning of social risks in the era of big data. This paper focuses on the three environments of diversification of stakeholders, risk media, and (...) big data era. The evolution characteristics of the social risk of environmental damage of large-scale construction projects are analyzed from the four stages of incubation, outbreak, mitigation, and regression in essence. On this basis, a social risk early warning model is constructed， and the multicenter network governance mode of social risk of environmental damage in large-scale construction projects and practical social risk prevention strategies in different stages are put forward. Experiments show that the long short-term memory neural network model is effective and feasible for predicting the social risk trend of environmental damage of large-scale construction projects. Compared with other classical models, the long short-term memory model has the advantages of strong processing capability and high early warning accuracy for time-sensitive data and will have broad application prospects in the field of risk control research. By using the network governance framework and long short-term memory model, this paper studies the environmental mass events of large-scale construction projects on the risk early warning method, providing reference for the government to effectively prevent and control social risk of environmental damage of large-scale construction project in China.
