- Modeling and Dynamic Control of a Class of Semibiomimetic Robotic Fish.ShouxuZhang,Bo Jiang,Xiaoxuan Chen,Jian Liang,Peng Cui &Xinxin Guo -2018 -Complexity 2018:1-8.This paper proposes a new robotic fish which avoids the complex mechanical structure and reduces the model complexity comparing to the existing bioinspired robotic fish, giving rise to a semibiomimetic robotic fish. The generalized Lagrange equation is adopted to establish the dynamic model of the robotic fish. The controllability of the system is analyzed, upon which a trajectory tracking control algorithm is designed by using the feedback linearization technique. The simulation results show that the dynamic model adopted in this paper (...) can achieve better control performance. (shrink)No categories
- Auditory and cross-modal attentional bias toward positive natural sounds: Behavioral and ERP evidence.Yanmei Wang,Zhenwei Tang,XiaoxuanZhang &Libing Yang -2022 -Frontiers in Human Neuroscience 16.Recently, researchers have expanded the investigation into attentional biases toward positive stimuli; however, few studies have examined attentional biases toward positive auditory information. In three experiments, the present study employed an emotional spatial cueing task using emotional sounds as cues and auditory stimuli or visual stimuli as targets to explore whether auditory or visual spatial attention could be modulated by positive auditory cues. Experiment 3 also examined the temporal dynamics of cross-modal auditory bias toward positive natural sounds using event-related potentials. (...) The behavioral results of the three experiments consistently demonstrated that response times to targets were faster after positive auditory cues than they were after neutral auditory cues in the valid condition, indicating that healthy participants showed a selective auditory attentional bias and cross-modal attentional bias toward positive natural sounds. The results of Experiment 3 showed that N1 amplitudes were more negative after positive sounds than they were after neutral sounds, which further provided electrophysiological evidence that positive auditory information enhances attention at early stages in healthy adults. The results of the experiments performed in the present study suggest that humans exhibit an attentional bias toward positive natural sounds. (shrink)
- A Diagnosis Framework for High-reliability Equipment with Small Sample Based on Transfer Learning.Jinxin Pan,Bo Jing,Xiaoxuan Jiao,Shenglong Wang &QingyiZhang -2022 -Complexity 2022:1-15.Conventional methods for fault diagnosis typically require a substantial amount of training data. However, for equipment with high reliability, it is arduous to form a large-scale well-annotated dataset due to the expense of data acquisition and costly annotation. Besides, the generated data have a large number of redundant features which degraded the performance of models. To overcome this, we proposed a feature transfer scenario that transfers knowledge from similar fields to enhance the accuracy of fault diagnosis with small sample. To (...) reduces the redundant information, data were filtered according to manifold consistency. Then, features were extracted based on CNN and feature transfer was conducted. For adequate fitness, the joint adaptation of conditional distribution and marginal distribution was used between the two domains. Minimum structural risk and MMD of adaptation were two indicators weighted for training the model. To test the efficiency of the model, we built an airborne fuel pump testbed, and contributed a new dataset that contained 15 categories of fault data, which serves as the small sample dataset in this research. Then the proposed model was applied in our experimental data. As a result, the fault diagnosis rate increases by 28.6% through our proposed model, which is more precise than other classical methods. The results of feature visualization further demonstrate that the features are more distinguished through the proposed method. All code and data are accessible on my GitHub. (shrink)

Bookmark - Effects of ethical leadership on nurses’ service behaviors.NaZhang,Mingfang Li,Zhenxing Gong &Dingxin Xu -2019 -Nursing Ethics 26 (6):1861-1872.Background: Nurses’ service behaviors have critical implications for hospitals. However, few studies had adequate ethical considerations of service behaviors and accounted for how organizational or individual antecedents can induce nurses to engage in service behaviors. In addition, they mainly focused on the one side of role-prescribed or extra-role service behavior. Objective: This study aims to explore the chained mediation effect of ethical climate and moral sensitivity on the relationship between organizational ethical leadership and nurses’ service behaviors and to examine the (...) relationship, from a comparative view, of the role-prescribed service behavior and extra-role service behavior. Methods: In all, 476 nurses from three tertiary hospitals were investigated with the Ethical Leadership Scale, Ethical Climate Scale, Moral Sensitivity Questionnaire and Service Behavior Questionnaire. Structural equation modeling was adopted to analyze the data. SPSS and Mplus statistical software was used in the data analysis. Ethical considerations: Approval was obtained from the Ethics Committee at School of Nursing, Hebei Medical University. Data privacy and confidentiality were maintained and assured by obtaining subjects’ informed consent to participate in the research before data collection. Results: The effects of ethical leadership on nurses’ service behaviors are mediated by two variables in turn: ethical climate and nurses’ moral sensitivity. Ethical climate and moral sensitivity partially mediated the relationship between ethical leadership and nurses’ role-prescribed service behavior and fully mediated the relationship between ethical leadership and nurses’ extra-role service behavior. Conclusion: Organizational ethical leadership positively affected ethical climate, which positively affected nurses’ moral sensitivity and affected both their role-prescribed service behavior and extra-role service behavior.

- Closure, deduction and hinge commitments.XiaoxingZhang -2021 -Synthese 198 (Suppl 15):3533-3551.Duncan Pritchard recently proposed a Wittgensteinian solution to closure-based skepticism. According to Wittgenstein, all epistemic systems assume certain truths. The notions that we are not disembodied brains, that the Earth has existed for a long time and that one’s name is such-and-such all function as “hinge commitments.” Pritchard views a hinge commitment as a positive propositional attitude that is not a belief. Because closure principles concern only knowledge-apt beliefs, they do not apply to hinge commitments. Thus, from the fact that (...) a subject knows that he is sitting in a room, and the fact that the subject’s sitting in a room entails his bodily existence, it does not follow that the subject also knows that he is not an envatted brain. This paper rejects Pritchard’s non-belief reading of hinge commitments. I start by showing that the non-belief reading fails to solve the skeptical paradox because the reasons that Pritchard uses to support the non-belief reading do not exempt hinge propositions from closure principles. I then proceed to argue that the non-belief reading is false as it claims that hinge commitments, unlike ordinary beliefs, are rationally unresponsive—with the help of a scenario in which a subject’s experience is internally chaotic, we can safely conclude that the hinge commitment that one is not systematically mistaken about the world is equally responsive to one’s evidential situations.

- Moral distress and its influencing factors: A cross-sectional study in China.Zhang Wenwen,Wu Xiaoyan,Zhan Yufang,Ci Lifeng &Sun Congcong -2018 -Nursing Ethics 25 (4):470-480.Objective:The purpose of this study was to describe the current situation of moral distress and to explore its influencing factors among Chinese nurses.Methods:This is an exploratory, descriptive design study. A total of 465 clinical nurses from different departments in three Grade-III, Level-A hospitals in Jinan, Shandong Province, completed the questionnaires, including demographics questionnaire, Chinese version of Moral Distress Scale–Revised, and Job Diagnostic Survey.Ethical considerations:The study was approved by the university ethics board and the local health service director.Results:The total score of (...) Moral Distress Scale–Revised was 36.01 ± 24.02 points. The mean frequency and intensity scores of moral distress were 1.13 ± 0.49 and 1.09 ± 0.58, respectively. The level of moral distress among Chinese clinical nurses was low, and the frequency and intensity of moral distress were on low to moderate level. The level of moral distress experienced by clinical nurses is associated with demographics features and job characteristics, including age, education degree, department, task significance, autonomy, and dealing with others.Conclusion:Our conclusion suggests that hospital and organizational administrations should attach much importance to the moral distress experienced by clinical nurses in China. Further studies should focus on interventions about how to reduce the levels of the frequency and intensity of moral distress among clinical nurses. (shrink)
- Workplace Spirituality and Unethical Pro-organizational Behavior: The Mediating Effect of Job Satisfaction.SuchuanZhang -2018 -Journal of Business Ethics 161 (3):687-705.This study aims to provide a comprehensive understanding about the mechanism that underlies the detrimental effects of workplace spirituality dimensions on employee unethical pro-organizational behavior, directly as well as indirectly, through job satisfaction. Using a sample consisting of 458 employees in various organizations in China, this study reveals that two dimensions of WPS are positively associated with UPB. Also the results of this paper show that each of the three dimensions of WPS has a significant positive relationship with job satisfaction. (...) Furthermore, this study successfully confirms the mediating effect of job satisfaction in the relationship between WPS dimensions and UPB. Finally, theoretical and practical implications, future research directions and limitations of this study are discussed at the end of this research article. (shrink)
- CEO Hubris and Firm Pollution: State and Market Contingencies in a Transitional Economy.LuZhang,Shenggang Ren,Xiaohong Chen,Dayuan Li &Duanjinyu Yin -2018 -Journal of Business Ethics 161 (2):459-478.This study focuses on CEO hubris and its effect on corporate unethical behaviour—pollution in particular, and in addition examines critical institutional contingencies [state ownership, political connection and industrial competition] which may moderate this effect. With data from over-polluting listed firms based on the real-time pollution monitoring system in transitional China from 2015 to 2017, we find that CEO hubris is significantly positively related to firm pollution, and that the moderating role of SO is not significant, that PC positively moderates the (...) hubris–pollution relationship and that industrial competition negatively moderates this relationship. These findings contribute to research on the upper echelon theory, institutional theory and the growing literature on emerging economies. (shrink)
- Status Threat and Ethical Leadership: A Power-Dependence Perspective.GuangxiZhang,Jianan Zhong &Muammer Ozer -2018 -Journal of Business Ethics 161 (3):665-685.Whether, how and when do leaders engage in ethical leadership as a response to status threat? We propose that leaders facing status threat are likely to develop ethical leadership behaviors toward subordinates. Drawing on power dependence theory, we theorize that experiencing status threat augments leaders’ dependence on subordinates who can provide them with status-relevant resources. Dependence on subordinates further motivates leaders to absorb the resource constraints through displaying ethical leadership. However, if leaders are able to obtain alternative resources to cope (...) with status threat, their dependence on subordinates is weakened. We conducted two studies to test the predictions. Using a moderation-of-process design, Study 1 found that when participants experienced status threat, they displayed more ethical leadership behaviors, but particularly so when their reward structure was team- rather than individual-based. Study 2 was a field study using a sample of 104 teams from two Chinese firms listed in the “Top 500 private enterprises in China.” We found that leaders who experienced more status threat were perceived to be more ethical by their subordinates, which was mediated by leaders’ perceptions of dependence on subordinates. The mediated effect was stronger for leaders who were less skilled in networking. Implications for theory on the contextual factors of ethical leadership, dependence, and status threat are discussed.

- Proving that China has a Profession of Engineering: A Case Study in Operationalizing a Concept Across a Cultural Divide.HengliZhang &Michael Davis -2017 -Science and Engineering Ethics 23 (6):1581-1596.This article assumes that a profession is a number of individuals in the same occupation voluntarily organized to earn a living by openly serving a moral ideal in a morally-permissible way beyond what law, market, morality, and public opinion would otherwise require. Our question is whether the concept of profession may have a far wider range than the term, so that, for example, pointing out that a certain language lacks a word for “profession” in our sense, is not enough to (...) show that those who speak the language also lack the concept. We believe the survey of 71 Chinese reported here begins to answer that question. This article has four parts. The first describes who was interviewed, how, when, and so on. The second describes some important features of the survey’s questions, explaining how the questions track the concept of profession. The third part reports and interprets the results relevant to our question. The forth defends a tentative answer to the question with which we began—arguing the survey supports the claim that China has a profession of engineering. This article should serve as a “proof of concept”, that is, a model for similar studies around the world both of engineering and of other occupations thought to be professions. (shrink)
- Cross-Domain Effects of Ethical Leadership on Employee Family and Life Satisfaction: the Moderating Role of Family-Supportive Supervisor Behaviors.ShuxiaZhang &Yidong Tu -2018 -Journal of Business Ethics 152 (4):1085-1097.Drawing on the work–family enrichment theory, the present study investigates the cross-domain effects of ethical leadership on employees’ family and life satisfaction. Moreover, it focuses on the mediating role of work–family enrichment and the moderated mediation process of family-supportive supervisor behaviors underlying the relationship between ethical leadership and employees’ family and life satisfaction. Using a sample of 371 employees and their immediate supervisors in China, we found that WFE mediated the relationship between ethical leadership and employee-rated and supervisor-rated family and (...) life satisfaction. Moreover, FSSB positively moderated the relationship between ethical leadership and WFE, such that the relationship was strengthened when FSSB were higher. Furthermore, the mediations of WFE between ethical leadership and employee-rated and supervisor-rated family and life satisfaction were also positively moderated by FSSB, such that the indirect effects were stronger when FSSB were higher. The theoretical and managerial implications of our findings are further discussed. (shrink)
- A New Universal Bundle Theory.RuoyuZhang -2018 -Philosophia 46 (2):473-486.Universal Bundle Theory holds that objects are fundamentally identical with bundles of universals. Universals are multiply instantiable properties. One popular objection to UBT concerns the possibility of distinct indiscernibles. There are mainly two replies in the literature, corresponding to two representative UBTs, which I shall call the Identity-View and the Instance-View. Each view faces serious problems. This paper proposes a new version of UBT and argues that it is better than these other two versions.No categories

- Weakening faithfulness : some heuristic causal discovery algorithms. Zhalama,JijiZhang &Wolfgang Mayer -2017 -International Journal of Data Science and Analytics 3 (2):93-104.We examine the performance of some standard causal discovery algorithms, both constraint-based and score-based, from the perspective of how robust they are against failures of the Causal Faithfulness Assumption. For this purpose, we make only the so-called Triangle-Faithfulness assumption, which is a fairly weak consequence of the Faithfulness assumption, and otherwise allows unfaithful distributions. In particular, we allow violations of Adjacency-Faithfulness and Orientation-Faithfulness. We show that the PC algorithm, a representative constraint-based method, can be made more robust against unfaithfulness by (...) incorporating elements of the GES algorithm, a representative score-based method; similarly, the GES algorithm can be made less error-prone by incorporating elements of the conservative PC algorithm. As our simulations demonstrate, the increased robustness seems to matter even when faithfulness is not exactly violated, for with only finite sample, distributions that are not exactly unfaithful may be sufficiently close to being unfaithful to make trouble.

- Multifractal Detrended Cross-Correlation Analysis of the Return-Volume Relationship of Bitcoin Market.WeiZhang,Pengfei Wang,Xiao Li &Dehua Shen -2018 -Complexity 2018:1-20.We investigate the cross-correlations of return-volume relationship of the Bitcoin market. In particular, we select eight exchange rates whose trading volume accounts for more than 98% market shares to synthesize Bitcoin indexes. The empirical results based on multifractal detrended cross-correlation analysis reveal that the nonlinear dependencies and power-law cross-correlations in return-volume relationship are found; all cross-correlations are multifractal, and there are antipersistent behaviors of cross-correlation for q=2; the price of small fluctuations is more persistent than that of the volume, while (...) the volume of larger fluctuations is more antipersistent; and the rolling window method shows that the cross-correlations of return-volume are antipersistent in the entire sample period.

- Engineering Ethics in China.HengliZhang &Michael Davis -2018 -Business and Professional Ethics Journal 37 (1):105-135.This article describes China’s century-long concern with the professional ethics of engineers, especially a succession of codes of engineering ethics going back at least to 1933. This description is the result both of our own archival research and of “philosophical history”, the application of concepts from the philosophy of professions to the facts historians (or we) have discovered. Engineers, historians, social scientists, and philosophers of technology, as well as students of professional ethics, should find this description interesting. It certainly provides (...) a reason to wonder whether those who write about codes of professional ethics as if they were an Anglo-American export unlikely to put down roots elsewhere might have overlooked many early codes outside English-speaking countries. While code writers in China plainly learned from Western codes, the Chinese codes were not mere copies of their Western counterparts. Indeed, the Chinese codes sometimes differed inventively from Western codes in form (for example, being wholly positive) or content (for example, protecting local culture). (shrink)
- Character Strengths, Strengths Use, Future Self-Continuity and Subjective Well-Being Among Chinese University Students.YonghongZhang &Mengyan Chen -2018 -Frontiers in Psychology 9:316048.The study was designed to explore the relationships among character strengths, strengths use, future self-continuity and subjective well-being. A total of 225 undergraduates completed paper-and-pencil questionnaires assessing character strengths, strengths use, future self-continuity and subjective well-being. Results suggested several character strengths were correlated with subjective well-being and the strongest correlations were found for hope, curiosity, zest, perseverance and love. All character strengths were significantly correlated with strengths use. Strengths use and future self-continuity were robustly correlated with subjective well-being. The mediation (...) analysis showed that strengths use mediates the relationship between character strengths and subjective well-being, and specifically, the indirect effects of strengths use varies from different character strengths. The moderated mediator suggested that future self-continuity moderated the mediation of strengths use because future self-continuity moderates the effect of strengths use on subjective well-being. Furthermore, the indirect effect of strengths use was stronger with high level of future self-continuity than those with low level of future self-continuity. The present findings make a contribution to understand the underlying mechanisms involving in character strengths are associated with higher level of well-being. Additionally, the findings expand knowledge about future self-continuity and its relation to strengths use and subjective well-being among undergraduates, having significant implications in the educational context.

- Agreeing to disagree and dilation.JijiZhang,Hailin Liu &Teddy Seidenfeld -unknownWe consider Geanakoplos and Polemarchakis’s generalization of Aumman’s famous result on “agreeing to disagree", in the context of imprecise probability. The main purpose is to reveal a connection between the possibility of agreeing to disagree and the interesting and anomalous phenomenon known as dilation. We show that for two agents who share the same set of priors and update by conditioning on every prior, it is impossible to agree to disagree on the lower or upper probability of a hypothesis unless (...) a certain dilation occurs. With some common topological assumptions, the result entails that it is impossible to agree not to have the same set of posterior probabilities unless dilation is present. This result may be used to generate sufficient conditions for guaranteed full agreement in the generalized Aumman-setting for some important models of imprecise priors, and we illustrate the potential with an agreement result involving the density ratio classes. We also provide a formulation of our results in terms of “dilation-averse” agents who ignore information about the value of a dilating partition but otherwise update by full Bayesian conditioning.

- A Pythagorean Fuzzy Multigranulation Probabilistic Model for Mine Ventilator Fault Diagnosis.ChaoZhang,Deyu Li,Yimin Mu &Dong Song -2018 -Complexity 2018:1-19.In coal mining industry, the running state of mine ventilators plays an extremely significant role for the safe and reliable operation of various industrial productions. To guarantee the better reliability, safety, and economy of mine ventilators, in view of early detection and effective fault diagnosis of mechanical faults which could prevent unscheduled downtime and minimize maintenance fees, it is imperative to construct some viable mathematical models for mine ventilator fault diagnosis. In this article, we plan to establish a data-based mine (...) ventilator fault diagnosis method to handle situations where engineers are absent or they are incapable of coming to a conclusion from multisource data. In the process of building the mine ventilator fault diagnosis model, considering that probabilistic rough sets could reduce the errors triggered by incompleteness, inconsistency, and inaccuracy without needing any additional assumptions and Pythagorean fuzzy multigranulation rough sets over the two universes’ model could effectively handle data representation, fusion, and analysis issues, we generalize the existing PF MGRSs over the two universes’ model to the PRS setting, as well as to further establish a novel model named Pythagorean fuzzy multigranulation probabilistic rough sets over two universes. In the granular computing paradigm, three types of PF MG-PRSs over two universes based on the risk attitude of engineers are proposed at first. Afterwards, several basic propositions of the newly proposed model are explored. Moreover, a PF multigranulation probabilistic model for mine ventilator fault diagnosis based on PF MG-PRSs over two universes is investigated. At last, a real-world case study of dealing with a mine ventilator fault diagnosis problem is given to illustrate the practicality of the presented model, and a validity test, a sensitivity analysis, and a comparison analysis are further explored to demonstrate the effectiveness of the presented model.

- Normalized Robust FOPID Controller Regulation Based on Small Gain Theorem.ShuoZhang &Lu Liu -2018 -Complexity 2018:1-10.In this paper, a normalized robust FOPID controller regulation algorithm is proposed. Only one parameter k is necessary to be tuned in the controller regulation process, so the proposed control algorithm is convenient to be applied on both fractional-order systems and integer-order systems. A robustness evaluation function is constructed based on the small gain theorem. Larger robustness evaluation function value will help the system achieve better robustness performance. Another parameter, β, is also available to serve as a tuning knob when (...) larger robust evaluation function value is needed. Therefore, the controlled systems can be stabilized and can achieve quite satisfactory robust control performance using the proposed algorithm. The corresponding robust analysis results are obtained according to different conditions in the discussion. For a special case of widely used fractional-order systems, the FOPI and FOID controllers are presented based on the same tuning scheme together with their robustness discussion. Some examples are shown to verify the robustness of systems controlled by the proposed algorithm. (shrink)No categories

- The Effect of Speech Variability on Tonal Language Speakers’ Second Language Lexical Tone Learning.KaileZhang,Gang Peng,Yonghong Li,James W. Minett &William S.-Y. Wang -2018 -Frontiers in Psychology 9.Speech variability facilitates non-tonal language speakers’ lexical tone learning. However, it remains unknown whether tonal language speakers can also benefit from speech variability while learning second language (L2) lexical tones. Researchers also reported that the effectiveness of speech variability was only shown on learning new items. Considering that the first language (L1) and L2 probably share similar tonal categories, the present study hypothesizes that speech variability only promotes the tonal language speakers’ acquisition of L2 tones that are different from the (...) tones in their L1. To test this hypothesis, the present study trained native Mandarin (a tonal language) speakers to learn Cantonese tones with either high variability (HV) or low variability (LV) speech materials, and then compared their learning performance. The results partially supported this hypothesis: only Mandarin subjects’ productions of Cantonese low level and mid level tones benefited from the speech variability. They probably relied on the mental representations in L1 to learn the Cantonese tones that had similar Mandarin counterparts. This learning strategy limited the impact of speech variability. Furthermore, the results also revealed a discrepancy between L2 perception and production. The perception improvement may not necessarily lead to an improvement in production. (shrink)
- Neutrosophic Regular Filters and Fuzzy Regular Filters in Pseudo-BCI Algebras.XiaohongZhang,Yingcan Ma &F. Smarandache -2017 -Neutrosophic Sets and Systems 17:10-15.Neutrosophic set is a new mathematical tool for handling problems involving imprecise, indetermi nacy and inconsistent data. Pseudo-BCI algebra is a kind of non-classical logic algebra in close connection with various non-commutative fuzzy logics. Recently, we applied neutrosophic set theory to pseudo-BCI al gebras. In this paper, we study neutrosophic filters in pseudo-BCI algebras. The concepts of neutrosophic regular filter, neutrosophic closed filter and fuzzy regular filter in pseudo-BCI algebras are introduced, and some basic properties are discussed. Moreover, the relationships (...) among neutrosophic regular filter, fuzzy filters and anti-grouped neutrosophic filters are prese nted, and the results are proved: a neutrosophic filter (fuzzy filter) is a neutrosophic regular filter (fuzzy regular filter), if and only if it is both a neutrosophic closed filter (fuzzy closed filter) and an anti-grouped neutrosophic filter (fuzzy anti-grouped filter).

- Causal discovery from nonstationary/heterogeneous data : skeleton estimation and orientation determination.KunZhang,Biwei Huang,JijiZhang,Clark Glymour &Bernhard Schölkopf -unknownIt is commonplace to encounter nonstationary or heterogeneous data, of which the underlying generating process changes over time or across data sets. Such a distribution shift feature presents both challenges and opportunities for causal discovery. In this paper we develop a principled framework for causal discovery from such data, called Constraint-based causal Discovery from Nonstationary/heterogeneous Data, which addresses two important questions. First, we propose an enhanced constraint-based procedure to detect variables whose local mechanisms change and recover the skeleton of the (...) causal structure over observed variables. Second, we present a way to determine causal orientations by making use of independence changes in the data distribution implied by the underlying causal model, benefiting from information carried by changing distributions. Experimental results on various synthetic and real-world data sets are presented to demonstrate the efficacy of our methods. (shrink)

- Formal Semantics of English Sentences with Tense and Aspect.WenyanZhang -2017 -ProtoSociology 34:197-216.As common expressions in natural language, sentences with tense and aspect play a very important role. There are many ways to encode their contributions to meaning, but I believe their function is best understood as exhibiting relations among related eventualities (events and states). Accordingly, contra other efforts to explain tense and aspect by appeal to temporal logics or interval logics, I believe the most basic and correct way to explain tense and aspect is to articulate these relations between eventualities. Building (...) on these ideas, I will characterize a formal semantics – Event-State Semantics (ESS) – which differs from all formal semantics based on temporal logics; in particular, one with which sentences with tense and aspect can be adequately explained, including molecular sentences and those with adverbial clauses.
