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 study had two aims: to test the effect and the effect size of specific problematic Internet use [online shopping, online pornography, social network site usage, and Internet gaming] on generalized problematic Internet use and to reveal the gender differences in GPIU and SPIU for students from the elementary school level to the university level. In total, 5,215 Chinese students from four types of schools provided self-report data on demographic variables, online shopping, online pornography, SNS usage, Internet gaming, and GPIU. (...) After calculations had been controlled for demographic variables, the results indicated that online shopping, online pornography, SNS usage, and Internet gaming positively predicted GPIU—and Internet gaming was the most critical predictor of GPIU—and that gender differences were revealed in Internet gaming and GPIU in all educational levels, except at senior high school where the gender differences in GPIU were not significant. Significant gender differences were found for online shopping and online pornography for all educational levels above elementary school. These results provided further understanding of the association between GPIU and SPIU and gender differences in PIU, which suggested that gender differences across different educational levels should be considered in interventions of PIU.

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)

While the definitions employed by different governmental agencies and scientific societies differ somewhat, the term “nanotechnology” is generally understood to refer to the manufacturing, characterization, and use of man-made devices with dimensions on the order of 1-100 nanometers. Devices that comprise a fundamental functional element that is nanotechnological are also frequently comprised within nanotechnology, as are manufactured objects with dimensions less than one micrometer. The differences in definition lead to occasional paradoxes, such as the fact that the most widely used (...) nanodrug is labeled a “nanopharmaceutical” by governments of European countries, Canada, and Australia, but it is not a nanotechnology for the U.S. Food and Drug Administration. It is also common in scientific domains to restrict the term “nanotechnology” to objects that possess special, “emerging” properties that only arise because of their nanoscale dimension. (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)

The neural basis of progress monitoring has received relatively little attention compared to other sub-processes that are involved in goal directed behavior such as motor control and response inhibition. Studies of error-monitoring have identified the dorsal anterior cingulate cortex (dACC) as a structure that is sensitive to conflict detection, and triggers corrective action. However, monitoring goal progress involves monitoring correct as well as erroneous events over a period of time. In the present research, 20 healthy participants underwent fMRI while playing (...) a game that involved monitoring progress towards either a numerical or a visuo-spatial target. The findings confirmed the role of the dACC in detecting situations in which the current state may conflict with the desired state, but also revealed activations in the frontal and parietal regions, pointing to the involvement of processes such as attention and working memory in monitoring progress over time. In addition, activation of the cuneus was associated with monitoring progress towards a specific target presented in the visual modality. This is the first time that activation in this region has been linked to higher-order processing of goal-relevant information, rather than low-level anticipation of visual stimuli. Taken together, these findings identify the neural substrates involved in monitoring progress over time, and how these extend beyond activations observed in conflict and error monitoring. (shrink)

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.

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.

Purpose.This paper presents a new method and model based on stochastic MULTIMOORA method and discuss its application to the doctor evaluation in healthcare service.Design/Methodology/Approach. In the previous studies, the number of decision group is often assumed to be small, and the different dimensions of the evaluation indexes were also less. In this paper, the authors study how to evaluate the healthcare service quality of doctors by the large group. Based on the stochastic MULTIMOORA theory, the authors use the method that (...) builds the function of the net probability, the distance between the ideal solutions, and the utility of each doctor.Findings.This paper presents a novel model to determine the optimal doctor that considers both two dimensions in the index system and balances the evaluation results of the two dimensions. The authors designed the questionnaire and conducted field survey to make the proposed method closer to the actual situation in China. Then, they determined the optimal evaluation result for the healthcare service quality of doctors.Research Limitations/Implications.In the process of practical decision-making, there are differences in intellectual literacy level, regional background, and language preference between different decision-makers. it is impossible for the method we proposed to consider the differentiation index system of decision-makers’ preference comprehensively. And this will be a further research direction.Practical Implications.The authors proposed two evaluation index dimensions and tryed to balance the evaluation results of the two dimensions as much as possible. Meanwhile, the information aggregation method based on stochastic MULTIMOORA is distinguished.Social Implications.The proposed method can be applied to the evaluation of doctors in actual healthcare service. It is helpful to improve the healthcare service quality and the hospital management level, further improve the core competition of hospitalsOriginality/Value.This paper makes up for the lack of existing studies of the large group evaluation decision in the healthcare service. A new method on the evaluation of doctors by the large group is established and applied to a healthcare management decision-making problem with Chinese characteristics in reality. (shrink)

The models used in social simulation to date have mostly been very simplistic cognitively, with little attention paid to the details of individual cognition. This work proposes a more cognitively realistic approach to social simulation. It begins with a model created by Gilbert (1997) for capturing the growth of academic science. Gilbert’s model, which was equation-based, is replaced here by an agent-based model, with the cognitive architecture CLARION providing greater cognitive realism. Using this cognitive agent model, results comparable to previous (...) simulations and to human data are obtained. It is found that while different cognitive settings may affect the aggregate number of scientific articles produced, they do not generally lead to different distributions of number of articles per author. The paper concludes with a discussion of the correspondence between our model and the constructivist view of academic science. It is argued that using more cognitively realistic models in simulations may lead to novel insights. (shrink)

Based on the self-verification theory, this research proposed a multi-level model for exploring whether, how, and when differentiated leadership had curvilinear effects on relationship conflict within a team and further on team members’ counterproductive work behaviors toward individuals (CWBI). Drawing on a sample of 297 team members nested in 78 teams, we found that differentiated empowering leadership had no direct curvilinear effects on relationship conflict. However, the results showed that the team competence variance could moderate the curvilinear relationship between differentiated (...) empowering leadership and relationship conflict. Specifically, only in teams with high competence variance among members, differentiated empowering leadership had a U-shaped effect on relationship conflict. Moreover, differentiated empowering leadership interacted with team competence variance had a downstream effect on team members’ CWBI through relationship conflict. We ended up by discussing the theoretical and practical implications of these findings. (shrink)

Philip J. Ivanhoe's translation of Sun Tzu's _Art of War_ will be warmly embraced by students. His discussion in the Introduction about the text’s dating and authorship, as well as Chinese attitudes towards things military, is concise, informative, and up-to-date. The translation itself is a marvel--its language is simple and direct, making it immensely readable and clear.--Keith Knapp, is Westvaco Professor of National Security Studies, Department of History, The Citadel, The Military College of South Carolina.

Like Machiavelli's The Prince and the Japanese Book of Five Rings, Sun Tzu's The Art of War is as timely for business people today as it was for military strategists in ancient China. Written in China more than 2,000 years ago, Sun Tzu's classic The Art of War is the first known study of the planning and conduct of military operations. These terse, aphoristic essays are unsurpassed in comprehensiveness and depth of understanding, examining not only battlefield maneuvers, but also relevant (...) economic, political, and psychological factors. Indeed, the precepts outlined by Sun Tzu regularly applied outside the realm of military theory. It is read avidly by Japanese businessmen and was touted in the movie Wall Street as the corporate raider's bible. Providing a much-needed translation of this classic, Samuel Griffith has made this powerful and unique work even more relevant to the modern world. Including an explanatory introduction and selected commentaries on the work, this edition makes Sun Tzu's strategical and tactical principles accessible not only students of Chinese history competition.

This study examines whether the gender of the directors on fully independent audit committees affects the ability of the committees in constraining earnings management and thus their effectiveness in overseeing the financial reporting process. Using a sample of 525 firm-year observations over the period 2003 to 2005, we are unable to identify an association between the proportion of female directors on audit committees and the extent of earnings management.

This article argues that consent must be revocable. I present two arguments for this conclusion. On the argument from informed consent, irrevocable consent lacks validity because it cannot be sufficiently informed. On the argument from bodily integrity, irrevocable consent lacks validity because we do not have the authority to deny our future selves the ability to protect our bodily integrity. I explain why the argument from bodily integrity captures unique moral problems raised by irrevocable consent and illuminates an important but (...) undertheorized distinction between autonomy and bodily integrity.
