    ""On the Undeniable Existence of the Systematic Theory of" Chinese Marxist Philosophy": A Response to Xu Suhua.Jianjie Lu - 2005 - Modern Philosophy 4:006.
    Mr. Xu Suhua article to my proposal of "Marxist Philosophy in China" is equivalent to what he calls "the guiding ideology of the party", "Marxist philosophy in China" is equivalent to what he calls "academic research form", which does not meet my intention. "Legality of Marxist philosophy," the discussion does exist. "Marxist Philosophy in China" in China, learning, using, in practical experience, to carry forward the fine Chinese culture and philosophy, the wisdom of the masses sublimation developed on the basis (...)

    A call for theory‐inspired analysis in qualitative research: Ways to construct different truths in and about healthcare.Stinne Glasdam, Hongxuan Xu & Ragnhild J. A. Gulestø - forthcoming - Nursing Inquiry:e12642.
    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 (...)

    Cooperative gazing behaviors in human multi-robot interaction.Tian Xu, Hui Zhang & Chen Yu - 2013 - Interaction Studies. Social Behaviour and Communication in Biological and Artificial Systemsinteraction Studies / Social Behaviour and Communication in Biological and Artificial Systemsinteraction Studies 14 (3):390-418.
    When humans are addressing multiple robots with informative speech acts, their cognitive resources are shared between all the participating robot agents. For each moment, the user’s behavior is not only determined by the actions of the robot that they are directly gazing at, but also shaped by the behaviors from all the other robots in the shared environment. We define cooperative behavior as the action performed by the robots that are not capturing the user’s direct attention. In this paper, we (...)

    The Creator-Determining Problem and Conjunctive Creationism about Fictional Characters.Min Xu - 2015 - Dialogue 54 (3):455-468.
    According to standard Creationism about fictional characters, each fictional character is created by its single author independently, or created by its co-authors cooperatively, or created by its independent authors independently. I argue that standard Creationism faces the Creator-Determining Problem. I propose a non-standard form of Creationism, i.e., Conjunctive Creationism, according to which each fictional character is conjunctively created. I argue that Conjunctive Creationism does not face the Creator-Determining Problem. By responding to four potential worries, I provide a further defense. My (...)

    Ethical Leadership Behavior and Employee Justice Perceptions: The Mediating Role of Trust in Organization.Angela J. Xu, Raymond Loi & Hang-yue Ngo - 2016 - Journal of Business Ethics 134 (3):493-504.
    Using data collected at two phases, this study examines why and how ethical leadership behavior influences employees’ evaluations of organization-focused justice, i.e., procedural justice and distributive justice. By proposing ethical leaders as moral agents of the organization, we build up the linkage between ethical leadership behavior and the above two types of organization-focused justice. We further suggest trust in organization as a key mediating mechanism in the linkage. Our findings indicate that ethical leadership behavior engenders employees’ trust in their employing (...)

    Predicting Missing Links Based on a New Triangle Structure.Shenshen Bai, Longjie Li, Jianjun Cheng, Shijin Xu & Xiaoyun Chen - 2018 - Complexity 2018:1-11.
    With the rapid growth of various complex networks, link prediction has become increasingly important because it can discover the missing information and predict future interactions between nodes in a network. Recently, the CAR and CCLP indexes have been presented for link prediction by means of different triangle structure information. However, both indexes may lose the contributions of some shared neighbors. We propose in this work a new index to make up the weakness and then improve the accuracy of link prediction. (...)

    CEOs’ Poverty Experience and Corporate Social Responsibility: Are CEOs Who Have Experienced Poverty More Generous?Shan Xu & Panyi Ma - 2022 - Journal of Business Ethics 180 (2):747-776.
    This study examines whether the chief executive officer’s poverty experience has an impact on firms’ corporate social responsibility. We find that firms’ CSR performance increases with CEOs’ poverty experience; specifically, firms with CEOs who experienced early-life poverty are associated with more socially responsible activities and fewer socially irresponsible activities, such as on-the-job consumption, and are more associated with key stakeholder-related rather than community-related CSR. We further find that the positive relationship between the CEO’s poverty experience and CSR strengthens for well-educated (...)

  13. Axioms for deliberative stit.Ming Xu - 1998 - Journal of Philosophical Logic 27 (5):505-552.
    Based on a notion of "companions to stit formulas" applied in other papers dealing with astit logics, we introduce "choice formulas" and "nested choice formulas" to prove the completeness theorems for dstit logics in a language with the dstit operator as the only non-truth-functional operator. The main logic discussed in this paper is the basic logic of dstit with multiple agents, other logics discussed include the basic logic of dstit with a single agent and some logics of dstit with multiple (...)

  14. Causation in branching time (I): Transitions, events and causes.Ming Xu - 1997 - Synthese 112 (2):137-192.
    We propose a theory of events and causes against the background of branching time. Notions discussed include possibility based on reality, transitions, events, determinacy, contingency, causes and effects. The main idea in defining causal relations is to introduce a certain preconditioning circumstance under which one event follows another. We also briefly compare this theory with some other theories.

    Enhancing Consumer Online Purchase Intention Through Gamification in China: Perspective of Cognitive Evaluation Theory.Yan Xu, Zhong Chen, Michael Yao-Ping Peng & Muhammad Khalid Anser - 2020 - Frontiers in Psychology 11.
    The application of game elements of gamification in online shopping is attracting interest from researchers and practitioners. However, it remains unclear how gamification affects and improves consumer purchase intention on online shopping platforms, which still leaves a gap in our knowledge. To narrow this theoretical gap, a theoretical model has been built in this study. This model adopts cognitive evaluation theory to explain the impact of gamification elements on consumer purchase intention. Data was collected from 322 online shopping consumers who (...)

    A Probabilistic Approach to Epistemic Safety from the Perspective of Ascribers.Yingjin Xu - 2022 - Episteme 19 (1):31-46.
    “Epistemic safety” refers to an epistemic status in which the subject acquires true beliefs without involving epistemic luck. There is a tradition of cashing out safety-defining modality in terms of possible world semantics, and even Julian Dutant's and Martin Smith's normalcy-based notions of safety also take this semantics as a significant component of them. However, such an approach has to largely depend on epistemologists’ ad hoc intuitions on how to individuate possible worlds and how to pick out “close” worlds. In (...)

  18. Combinations of Stit and Actions.Ming Xu - 2010 - Journal of Logic, Language and Information 19 (4):485-503.
    We present a simple theory of actions against the background of branching time, based on which we propose two versions of an extended stit theory, one equipped with particular actions and the other with sets of such actions. After reporting some basic results of a formal development of such a theory, we briefly explore its connection to a version of branching ETL.

  19. Early confucian principles: The potential theoretic foundation of democracy in modern china.Keqian Xu - 2006 - Asian Philosophy 16 (2):135 – 148.
    The subtle and complex relation between Confucianism and modern democracy has long been a controversial issue, and it is now again becoming a topical issue in the process of political modernization in contemporary China. This paper argues that there are some quite basic early Confucian values and principles that are not only compatible with democracy, but also may become the theoretic foundation of modern democracy in China. Early Confucianism considers 'the people's will' as the direct representative of 'Heaven's will', with (...)

    Does Education Affect Rural Women’s Trust? Evidence From China.Siyu Xu, Yeye Zhao, Noshaba Aziz & Jun He - 2022 - Frontiers in Psychology 13.
    Trust is of great significance to the economic and social development of a country. In the case of China, the trust of rural women has undergone tremendous changes along with the development of rural areas. It is seen that the trust of rural women has changed from localized to generalized trust, and it is stated that the major factor leading to this transformation is education. To explore the phenomenon empirically, the current study uses the survey data of rural women sourced (...)

    Early Word Order Usage in Preschool Mandarin-Speaking Typical Children and Children With Autism Spectrum Disorder: Influences of Caregiver Input?Ying Alice Xu, Letitia R. Naigles & Yi Esther Su - 2022 - Frontiers in Psychology 12.
    This study explores the emergence and productivity of word order usage in Mandarin-speaking typically-developing children and children with autism spectrum disorder, and examines how this emergence relates to frequency of use in caregiver input. Forty-two caregiver-child dyads participated in video-recorded 30-min semi-structured play sessions. Eleven children with ASD were matched with 10 20-month-old TD children and another 11 children with ASD were matched with 10 26-month-old TD children, on expressive language. We report four major findings: Preschool Mandarin-speaking children with ASD (...)

    We present a theory of actions based on a theory of events in branching time, in which "particular" or "token" actions are taken to be sets of transitions from their initial states to the outcomes. We also present a simple theory of composition of events by which composite events can be formed out of other events. Various kinds of actions, including instantaneous group actions and sequential group actions, are introduced by way of composition, and an extended stit theory of agency (...)

    Does honesty result from the absence of temptation or the active resistance of temptation? The “will’’ hypothesis suggests that honesty results from the active resistance of temptation, while the ”grace” hypothesis argues that honesty results from the absence of temptation. We examined reaction time and measured the cheating behavior of individuals who had a chance to lie for money. In study 1, we tested the “grace” hypothesis that honesty results from the absence of temptation and found a priming effect of (...)

    Challenges to Professional Independence in a Relational Society: Accountants in China.Gina Xu & Steven Dellaportas - 2019 - Journal of Business Ethics 168 (2):415-429.
    This study examines the tensions between the western concept of professional independence and accountants’ commitment to significant others under the care perspective of guanxi. The principle of professional independence is founded on arm’s-length transactions to avoid undue influence on professional and ethical judgement. However, in the relational society of China, social interactions based on Confucianism elicit a duty of care and concern towards significant others in important relationships. For a professional accountant, the commitment to persons with whom they have guanxi (...)

    Although being widely considered as only a Western tradition, individualism is not absent in traditional Chinese philosophy and culture. In some of the classic Chinese philosophic works such as Zhuangzi, we can clearly identify some elements which can be appropriately attributed to “individualism”, such as the awareness of individual “self” as an independent and unique existence, advocating individual freedom and liberty, emphasizing on the value and dignity of individual life, favoring individuals’ autonomy and privacy, pursuing unconstrained development in personality and (...)

    Dynamic Evolution Analysis of Stock Price Fluctuation and Its Control.Yuhua Xu, Zhongyi Ke, Chengrong Xie & Wuneng Zhou - 2018 - Complexity 2018:1-9.
    This paper studies a simple dynamical system of stock price fluctuation time series based on the rule of stock market. When the stock price fluctuation system is disturbed by external excitations, the system exhibits obviously chaotic phenomena, and its basic dynamic properties are analyzed. At the same time, a new fixed-time convergence theorem is proposed for achieving fixed-time control of stock price fluctuation system. Finally, the effectiveness of the method is verified by numerical simulation.

The controversy is beyond the framework of affinity chemistry and entail a synthesis of meta-chemical thinking and experiments. Proust’s discovery of the law of definite proportions not only (...)
