Continuous subgraph matching problem on dynamic graph has become a popular research topic in the field of graph analysis, which has a wide range of applications including information retrieval and community detection. Specifically, given a query graph q, an initial graph G 0, and a graph update stream △ G i, the problem of continuous subgraph matching is to sequentially conduct all possible isomorphic subgraphs covering △ G i of q on G i. Since knowledge graph is a directed labeled (...) multigraph having multiple edges between a pair of vertices, it brings new challenges for the problem focusing on dynamic knowledge graph. One challenge is that the multigraph characteristic of knowledge graph intensifies the complexity of candidate calculation, which is the combination of complex topological and attributed structures. Another challenge is that the isomorphic subgraphs covering a given region are conducted on a huge search space of seed candidates, which causes a lot of time consumption for searching the unpromising candidates. To address these challenges, a method of subgraph-indexed sequential subdivision is proposed to accelerating the continuous subgraph matching on dynamic knowledge graph. Firstly, a flow graph index is proposed to arrange the search space of seed candidates in topological knowledge graph and an adjacent index is designed to accelerate the identification of candidate activation states in attributed knowledge graph. Secondly, the sequential subdivision of flow graph index and the transition state model are employed to incrementally conduct subgraph matching and maintain the regional influence of changed candidates, respectively. Finally, extensive empirical studies on real and synthetic graphs demonstrate that our techniques outperform the state-of-the-art algorithms. (shrink)

Subgraph matching on a large graph has become a popular research topic in the field of graph analysis, which has a wide range of applications including question answering and community detection. However, traditional edge-cutting strategy destroys the structure of indivisible knowledge in a large RDF graph. On the premise of load-balancing on subgraph division, a dominance-partitioned strategy is proposed to divide a large RDF graph without compromising the knowledge structure. Firstly, a dominance-connected pattern graph is extracted from a pattern graph (...) to construct a dominance-partitioned pattern hypergraph, which divides a pattern graph as multiple fish-shaped pattern subgraphs. Secondly, a dominance-driven spectrum clustering strategy is used to gather the pattern subgraphs into multiple clusters. Thirdly, the dominance-partitioned subgraph matching algorithm is designed to conduct all isomorphic subgraphs on a cluster-partitioned RDF graph. Finally, experimental evaluation verifies that our strategy has higher time-efficiency of complex queries, and it has a better scalability on multiple machines and different data scales. (shrink)

This article proposes a unified framework for understanding creative problem solving, namely, the explicit–implicit interaction theory. This new theory of creative problem solving constitutes an attempt at providing a more unified explanation of relevant phenomena (in part by reinterpreting/integrating various fragmentary existing theories of incubation and insight). The explicit–implicit interaction theory relies mainly on 5 basic principles, namely, (a) the coexistence of and the difference between explicit and implicit knowledge, (b) the simultaneous involvement of implicit and explicit processes in most (...) tasks, (c) the redundant representation of explicit and implicit knowledge, (d) the integration of the results of explicit and implicit processing, and (e) the iterative (and possibly bidirectional) processing. A computational implementation of the theory is developed based on the CLARION cognitive architecture and applied to the simulation of relevant human data. This work represents an initial step in the development of process-based theories of creativity encompassing incubation, insight, and various other related.. (shrink)

Despite the prevailing discourses on the importance of top management ethical leadership, related theoretical and empirical developments are lacking. Drawing on institutional theory, we propose that top management ethical leadership contributes to organizational outcomes by promoting firm-level ethical and procedural justice climates. This theoretical framework was empirically tested using multi-source data obtained from 4,468 employees of 147 Korean companies from various industries. The firm-level analysis shows that top management ethical leadership significantly predicts ethical climate, which then results in procedural justice (...) climate that fully mediates the effects of top management ethical leadership on two organizational outcomes, namely, firm-level organizational citizenship behavior and firm financial performance. The present study provides a plausible theoretical account and empirical validation of a mechanism through which top management ethical leadership enhances organizational performance. (shrink)

A survey study was conducted to look into the effect of Confucian ethics and the psychological foundations of morality on business managers' perspectives on corporate social responsibility (CSR). Using responses from 393 Chinese managers, we first conducted confirmatory factor analysis to assess the reliability and validity of the measurement model and then employed hierarchical regression to explore the relationships among Confucian ethics, moral foundations, and managers' shareholder value perspectives. The results indicate that both Confucian ethics and managers' moral foundations had (...) significant influence on shareholder value perspectives. In fact, moral foundations and Confucian ethics interacted and jointly affected managers' positions on the shareholder value model of corporate responsibility. This study demonstrates the importance of psychological foundations of morality to managers' CSR orientations and substantiates the persistent impact of Confucian ethics/cultural traditions on today' business practices.

Animal models of human diseases are often used in biomedical research in place of human subjects. However, results obtained by animal models may fail to hold true for humans. One way of addressing this problem is to make animal models more similar to humans by placing human tissue into animal models, rendering them chimeric. Since technical and ethical limitations make neurological disorders difficult to study in humans, chimeric models with human neural tissue could help advance our understanding of neuropathophysiology. In (...) this article, we examine whether the introduction of human neural tissue and any consequent cognitive change is relevant to the way we ought to treat chimeras. We argue that changes in cognitive abilities are morally relevant to the extent that they increase the capacities that affect the moral status of any entity, including awareness, autonomy, and sociability. We posit that no being, regardless of species, should be treated in a way that is incommensurate with its moral status. Finally, we propose a framework that can be used to guide ethical assessment of research involving chimeras with advanced cognitive capacities. We advance this framework as a useful tool for bringing relevant considerations to the forefront for those considering the ethical merit of proposed chimeric research. In doing so, we examine concepts relevant to the question of how any entity may be treated, including moral status, dignity, and capacities. (shrink)

Intelligent machines are no longer distant fantasies of the future or solely used for industrial purposes; they are real “living” things that operate similarly to humans with verbal and nonverbal communication capabilities. Humans see in such technology the horrifying dangers and the bliss enabled by the saving power. Entrenched in the emotions of hope and fear concerning intelligent machines, humans’ attitudes toward intelligent machines are not free of expectations, judgments, strategies, and selfish agendas. As the discovery of the New Worlds (...) has led to the development of an understanding of self as distinct from the other, narratives on intelligent robots have taken on similar forms of colonial discourse: contradictory manifestations of ethnocentrism (anthropocentrism) and exoticism. Similar to colonial encounters, the racialized Mechanical _Other_ operates like any other marginalized group. Colonial discourse often regards the mechanical _Other_ as both inferior yet exotic, which usually produces a mixed sense of blessing and curse, ambivalence composed of both desire and aversion. In these representations of machinic _otherness,_ one should not miss the fundamental injustice of creating the “Machinic Other” and imposing humans’ viewpoints. The field must expand the purview of intelligent machines to consider the larger historical and cultural forces shaping our understanding of who we are as reflected in the mirror of intelligent machines.

Finance ethics have drawn increasing attention from both government regulators and academic researchers. This paper addresses the issue of insider trading ethics. Previous studies on insider trading ethics have failed to provide convincing arguments and consistent results. In particular, the arguments against insider trading are based primarily on moral and philosophical grounds and lack empirical rigor. This study intends to establish and examine the relationship between the ethical issue and economic issue of insider trading. We argue that the ethics of (...) insider trading is in essence an economic rather than a moral issue. It is so far not clear to what extent insider trading may increase or decrease shareholders wealth. Until then, we must take care to avoid over-regulating insider trading. (shrink)

The evolution of Euler diagrams is examined from Euler's original system through the modifications made by Venn and Peirce. It is shown that these modifications were motivated by an attempt to increase the expressivity of the diagrams, but that a side effect of these modifications was a loss of the visual clarity of Euler's original system. Euler's original system is reconstructed from a modern, logical point of view. Formal semantics and rules of inference are provided for this reconstruction of Euler's (...) system, and basic logical properties are proved. (shrink)

Humor is a contextual phenomenon that exists in all societies, although the impact of humor may differ across different cultures. The data for this research was collected using an ethnographic approach, incorporating participant observation and semi-structured interviews. Based in three different South Korean organizations, this research offered the opportunity to interact in depth with workers of varying ages, genders, hierarchical levels, and organizational roles. Observations were complimented by 46 in-depth interviews and ad hoc follow-up discussions. This paper adopts a Confucian (...) perspective to understand the perception and use of workplace humor in these South Korean organizations. Confucian philosophy emphasizes the value of formality within society in order to maintain respectful relationships between individuals. We suggest that humor is used in these South Korean workplaces to support traditional Confucian values of harmony and hierarchy, and the changing cultural values in these workplaces influence humor perceptions in complex ways. The Confucian value of harmony maintained through the idea of hierarchy creates pressure for organizational members, to accept and cope with contentious humor in the workplace. In particular, the clash between the need to maintain harmonious relationships in the workplace (through obedience towards superiors) and the desire to reject some types of humor highlights issues for younger organizational members. Internal conflict creates distress for younger employees who may hold more Westernized values and this affects their emotional, psychological well-being. This study presents a cross-cultural perspective to organizational humor, and suggests that humor may not always be a positive experience for organizational members, but instead may create psychological distress in some employees.

With the emergence of environmental sustainability and green business management, increasing demands have been made on businesses in the areas of environmental corporate social responsibility. Furthermore, the influence of ECSR on green capital investment, environmental performance, and business competitiveness has also been the subject of attention from enterprises. However, in previous studies, the mediating role of green information technology capital in the relationship between ECSR, environmental performance, and business competitiveness, has not been investigated by researchers. In order to bridge this (...) gap in the ECSR literature, this study aims to examine the influence of ECSR on green IT capital, and the consequent effect of green IT capital on environmental performance and business competitiveness. Data were collected from 358 companies from the top 1000 manufacturers in Taiwan. The results confirmed that ECSR has significant positive effects on green IT human capital, green IT structural capital, and green IT relational capital. Green IT structural capital and green IT relational capital have positive effects on environmental performance and business competitiveness, and environmental performance has a positive effect on business competitiveness. In addition, green IT structural capital and green IT relational capital have partial mediating effects on ECSR, environmental performance, and business competitiveness. The implications and suggestions for future research are discussed. (shrink)

Background: Infectious disease outbreaks such as COVID-19 and MERS pose a major threat to healthcare workers' physical and mental health. Studies exploring the positive changes gained from adapting to traumatic events, known as post-traumatic growth, have attracted much attention. However, it is unclear which factors or experiences lead to PTG among HCWs. The purpose of this mixed-method study was to investigate factors associated with PTG among HCWs who experienced the MERS outbreak in South Korea, and fully describe their experience of (...) developing PTG.Methods: Quantitative data from 78 participants were collected using psychometric tools for Psychological distress, Resilience, and Support for coping, and Post-traumatic growth. Qualitative interviews were conducted with seven nurses. Data were analyzed using the qualitative content analysis method according to the sub-themes of resilience, which was the main factor associated with PTG.Results: We found resilience to have a significant impact on PTG. Thus the qualitative interviews were analyzed using the core concepts of resilience. Qualitative interviews with nurses illustrated how participants experienced the development of resilience in terms of its sub-factors: hardiness, persistence, optimism, and support.Conclusion: HCWs who endured the MERS outbreak showed high levels of PTG, and the analysis of the interview data provided a fuller understanding on the experience of remaining resilient and developing PTG. These results provide practical and pragmatic information helpful for developing intervention strategies and protocols that can help HCWs transform adversity into growth and development. (shrink)

Emojis and stickers are becoming increasingly popular in computer mediated communications. The present study examined the associations between personality traits and people’s reasons and patterns for using both emojis and stickers. Participants (n= 312) completed three on-line questionnaires assessing shyness, the Big Five personality traits and why and how they used emojis and stickers. Results revealed that shyness, neuroticism, extraversion and agreeableness were correlated with different reasons of usage. Moreover, some participants exhibited a tendency to adjust frequency of usage depending (...) on who the target person was and whether they were in a private or group chat. People who showed such tendencies were found to differ in personality with those who did not. Some differences in usage patterns were also observed between emojis and stickers. Together, the present study sheds more insights into how emojis and stickers can help people with different personality traits to achieve different purposes in their daily communication. (shrink)

The creative thinking and ability of top management team members is important in coping with rapid changes in the external environment and improving the competitive advantage of an organization. This research focuses on the CEO–TMT interface to explain how CEOs influence TMT characteristics, which in turn affects TMT outcomes. Based on social learning theory, this study examines the associations among CEO ethical leadership, TMT cohesion and TMT creativity in a Chinese context using a total of 91 top management teams. To (...) verify the reliability and validity of the constructs, a series of confirmatory factor analyses (CFAs) were run. The results showed that the hypothesized model captured distinct constructs and fits the data well. Multistep regression method was used to test hypotheses. The results indicated that (a) CEO ethical leadership has a positive effect on TMT creativity; (b) TMT cohesion plays a mediating role in the relationship between CEO ethical leadership and TMT creativity; and (c) power distance plays a moderating role in the relationship between CEO ethical leadership and TMT creativity. The greater the power distance, the weaker the positive relationship between CEO ethical leadership and TMT creativity. This study demonstrates the value of CEO ethical leadership and advocates the importance of establishing team cohesion and building a psychologically safe environment to motivate top managers within an organization to share information and knowledge to improve creativity.

In 2001, China’s moral education curriculum reform called for a returning to life as a radical shift from its previous empty sermonic pedagogy, hoping to cultivate its twenty-first century children into ethical humans. Accordingly, a notion of ‘human ecology’ appeared in the post-2001 textbook design, which became ‘co-being with’ in the latest 2016 textbook redesign. This paper picks up this co-being with as a philosophical, ethical, and ecological notion and scrutinizes its relevance to the discursive construction of China’s moral child (...) in two steps. First, it draws upon Heidegger’s thinking and the Chinese Daoist ecological understanding to explicate the philosophical significance of this ‘co-being with’ for moral education. Second, it unpacks the discursive embodiments of this ethical–ecological co-being with in connection with the construction of moral subjects in the post-2001 and 2016 textbooks. Through rigorous textual analysis, this paper finds that the post-2001 textbook discourses embody an instrumental trope and a subject vs object binary style of reasoning, which possibly makes egoistic rather than ethical children. The 2016 textbook discourses, especially those on the theme of co-being with, however, constrain the above instrumentality and envision cultivating ethical children. This paper argues this theorized co-being with provides some implications for moral education in China and the world, meanwhile raising some pedagogical challenges as well. (shrink)

Learners are able to use 2 different types of knowledge to perform a skill. One type is a conscious mental model, and the other is based on memories of instances. The authors conducted 3 experiments that manipulated training conditions designed to affect the availability of 1 or both types of knowledge about an artificial grammar. Participants were tested for both speed and accuracy of their ability to generate letter sequences. Results indicate that model-based training leads to slow accurate responding. Memorybased (...) training leads to fast, less accurate responding and highest achievement when perfect accuracy was not required. Evidence supports participants’ preference for using the memory-based mode when exposed to both types of training. Finally, the accuracy contributed by model-based training declined over a retention interval. (shrink)

Researchers have identified 2 distinctive types of pictorial displays, namely, pictorial metaphor and pictorial simile, and offered theoretical explanations of them. Regarding the distinction between pictorial metaphor and pictorial simile, we argue that symmetric image alignment of pictorial components depicting things at the object level is the principal design factor that sets pictorial simile apart from pictorial metaphor and links pictorial simile to pictorial grouping. Based on the idea of symmetric image alignment, an attempt is made to identify and explain (...) a further type of pictorial display, namely, pictorial oxymoron. We propose a hypothesis, called the "image grouping hypothesis," to provide an integrated account of pictorial grouping, pictorial simile, and pictorial oxymoron. The hypothesis can be summed up as follows: Symmetric image alignment of pictorial components depicting things of the same kind is apt for expressing pictorial grouping; symmetric image alignment of pictorial components depicting things of different kinds is apt for expressing pictorial simile; and symmetric image alignment of pictorial components depicting things that can be seen as incompatible with each other is apt for expressing pictorial oxymoron.

Tax haven investment has become an increasingly important topic in business ethics. Given the considerable tax haven investments from emerging market firms, understanding how home-country institutions shape their investments in tax havens is theoretically intriguing and practically crucial. By integrating resource dependence and institutional theories, we hypothesize the existence of a negative relationship between firms’ home-country political status and tax haven investment. State-owned enterprises controlled by the central government dominate the political hierarchy. Compared with other types of enterprises, central SOEs (...) receive the strongest institutional support and are the most prone to institutional oversight, thereby exhibiting the weakest tendency to invest in tax havens. This top group is followed by SOEs controlled by local governments, politically connected private firms, and private firms without political connections. These groups exhibit an increasing tendency to invest in overseas tax havens. The empirical analysis of Chinese listed firms during 2003–2013 supports our hypotheses. This research contributes to the business ethics literature by identifying institutional drivers of overseas tax haven investment by emerging market firms, thereby adding to the ethical debate on international tax avoidance.

Moral injury is a significant issue for healthcare workers, often stemming from exposure to ethical dilemmas and distressing events. This study aims to explore the relationship between moral injury and healthcare workers’ career calling, using the job demands-resources model as a theoretical framework. The goal is to understand how moral injury affects healthcare workers’ sense of purpose and vocation and identify factors that may mitigate this impact. A cross-sectional survey was conducted with a sample of 506 Chinese healthcare workers. The (...) study used self-report questionnaires to assess moral injury, authentic self-expression, self-compassion, ethical leadership, and career calling. Path analysis was used to test the proposed mediating and moderating relationships within the job demands-resources model. Moral injury has a negative effect on healthcare workers’ career calling. This effect is mediated by authentic self-expression – the inability to openly discuss moral distress weakens the sense of purpose. Self-compassion and ethical leadership buffer against the negative impact of moral injury on career calling. This research contributes to the understanding of moral injury and career calling in healthcare workers, with practical implications for safeguarding healthcare professionals’ well-being and commitment to their vocation.

Empirical research in Chinese organizations indicates differences in work-related values between different age groups. The authors compared people (older age group) with work experience from the pre-reform period – pre-1978 China, with those who started their work life in a society that had already changed and become open to foreign investments (younger age group). The authors created a model of institutionally sensitive work-related values. The results (...) could help multinational companies achieve competitive advantage. (shrink)

Transcranial magnetic stimulation, as a relatively new type of treatment, is a safe and non-invasive method for pain therapy. Here, we used CiteSpace software to visually analyze 440 studies concerning transcranial magnetic stimulation in pain research from 2010 to 2021, indexed by Web of Science, to clarify the research hotspots in different periods and characterize the process of discovery in this field. The United States ranked first in this field. Lefaucheur JP, Fregni F, and Andrade ACD made great contributions to (...) this field of study. The most prolific institution was University of São Paulo. The four main hot keywords were neuropathic pain, motor cortex, connectivity, and non-invasive brain stimulation. There were three main points that were generally accepted: definite analgesic effect of high-frequency rTMS of M1 contralateral to pain side in neuropathic pain; there are inconclusive recommendations regarding rTMS of the dorsolateral prefrontal cortex in fibromyalgia and neuropathic pain; there is low-quality evidence that single doses of high-frequency rTMS of the motor cortex may have short-term effects on chronic pain. This bibliometric analysis indicated that prospective, multi-center, large-sample, randomized controlled trials are still needed to further verify the effectiveness of various transcranial magnetic stimulation parameters in pain research.

This paper explores global K-pop's negotiation and reconstruction of Korean aesthetics via the dismantling, adoption, appropriation, and transfiguring of central elements of Korean traditional culture. Recently, K-pop groups have been incorporating traditional music and dance (gugak), traditional attire (hanbok), traditional houses (hanok), and old palaces (gogung) into music videos disseminated globally over digital platforms like YouTube. In their efforts to incorporate more 'Koreanness' into their musical productions and neutralize criticisms of their use of the 'K' prefix as inauthentic and unconnected (...) to Korean aesthetics, groups like BTS and BLACKPINK are redefining 'K-heritage' for music consumers worldwide. Along with other globally consumed Hallyu productions like K-movies, K-dramas, and K-games, K-Pop is in the process of reconstructing Koreans' and the world's view of the meaning of Korean-ness.

Many festivals use animals in the name of continuing traditions and religious acts of historical and cultural relevance, as well as for tourist entertainment; however, the welfare of these animals has been overlooked in favor of maintaining cultural identity or making economic profits. The criticism of animal-based festivals has been growing along with the increased public awareness of animal rights. However, this change in public perception has not yet been translated into actual government policies in Korea. This study addresses the (...) unethical practices and challenges regarding animal welfare at festivals from the perspective of visitors to understand the public perception of the need for institutional and regulatory interventions to improve the treatment of animals at festivals. An online survey (N = 1000) is conducted to examine the public perception of animals and animal welfare at festivals and how strongly online survey participants support organizer- and state-level actions to protect the welfare of festival animals. Logistic regression analyses identify gender, pet ownership, pro-animal attitude, visiting experience, sensitivity to criticism regarding animal issues, and perception of animal welfare at festivals as significant predictors of online survey participants’ support for actions ensuring the welfare of animals used in festivals. Our findings also suggest that people sympathize with the need to enhance animal welfare but have low levels of sensitivity to the maltreatment of animals at festivals, indicating the existence of cognitive dissonance. Establishing guidelines and regulations for improving animal welfare can help festivals use animals in a more sustainable way and make visitors rethink and re-establish human–animal relationships.

Background and purposeThis study aimed to analyze the feasibility and safety of endovascular therapy (EVT) in patients with acute posterior circulation stroke and vertebrobasilar dolichoectasia (VBD).Materials and methodsBASILAR was a national prospective registry of consecutive patients with symptomatic and imaging-confirmed acute stroke in the posterior circulation within 24 h of symptom onset. We evaluated EVT feasibility and safety in patients with VBD. Primary outcomes included improvement in modified Rankin Scale scores (mRS) at 90 days and mortality within 90 days. The (...) secondary outcome was the rate of favorable functional outcome, defined as mRS ≤ 3 (indicating independent ambulation) at 90 days. Safety outcomes included surgery-related complications and other serious adverse events.ResultsA total of 534 cases were included: 159 with VBD and 375 controls. No significant difference in mRS at 90 days was found between groups, but patients with VBD had a higher baseline National Institutes of Health Stroke Scale (NIHSS) score [30 (19–33) vs. 25 (15–32)] and were older [65 (59–74) vs. 63 (55–72) year]. After propensity score matching, there were no significant differences in baseline NIHSS score between the two groups, and the efficacy and safety of EVT were similar between patients with or without VBD. Furthermore, the prognostic effect of puncture-to-recanalization time on the probability of mortality within 90 days in EVT-treated patients with VBD was significant {adjusted odds ratio, 1.008 [95% confidence interval (1.001–1.015)]}.ConclusionEndovascular therapy is safe and feasible in patients with acute posterior circulation stroke and VBD. The puncture-to-recanalization time is important for predicting the prognosis of EVT-treated patients with VBD. (shrink)

The present study examines whether collaborative situations make individuals more dishonest in face-to-face settings. It also considers how this dishonesty unfolds over time. To address these questions, we employed a sequential dyadic die-rolling task in which two participants in a pair sitting face-to-face received a payoff only if both reported the same outcome when each one rolled their die. In each trial, one participant rolled a die first and reported the outcome. Then, the second participant was informed of A’s reported (...) number, rolled a die as well, and reported the outcome. If their reported outcomes were identical, both of them received a reward. We also included an individual condition in which an individual subject rolled a die twice and received a reward if he/she reported the same die-roll outcome. We found that B lied significantly more than participants in the individual condition, whereas A lied as much as participants in the individual condition. Furthermore, when collaborating, more and more participants became dishonest as the game progressed, whereas there was no such trend among participants in the individual condition. These findings provide evidence indicating that collaborative settings increase dishonesty and that this effect becomes more evident as the collaboration progress. (shrink)

With the prevalence of the Internet and new media channels, consumer reviews have become one of the main determinants of Consumers’ purchasing decisions. This paper uses the Latent Dirichlet Allocation (LDA) model to identify the key factors that are of major concern to consumers, including design factors, laptop setup factors, logistics factors, after-sales factors, and user experience factors. And, we classify these factors into product quality factors and supporting service factors for new products. We then explore the relationship between online (...) reviews and purchase decisions under these different factors, and also further explore the impact of interactions between online review metrics on purchase decisions. Our findings suggest that the impact of online reviews on consumer purchase decisions also varies considerably across different consumer focus factors. In addition, we find that the impact of the interaction between online review features is complex. In particular, consumers do not follow the positive guidance and make purchase decisions as we would expect when confronted with a large number of positive emotional polarity online reviews. Meanwhile, the interaction between negative emotional polarity and variance of online reviews had no significant effect on consumer purchase decisions. The variance of online reviews has a limited role in reducing consumer risk perceptions triggered by negative emotional polarity. Our study provides new evidence for the study of the impact of online reviews through text mining. (shrink)
