    Degrees of D. C. E. Reals.Rod Downey, Guohua Wu & Xizhong Zheng - 2004 - Mathematical Logic Quarterly 50 (45):345-350.
    A real α is called a c. e. real if it is the halting probability of a prefix free Turing machine. Equivalently, α is c. e. if it is left computable in the sense that L = {q ∈ ℚ : q ≤ α} is a computably enumerable set. The natural field formed by the c. e. reals turns out to be the field formed by the collection of the d. c. e. reals, which are of the form α—β, where (...)

    Isolation and Lattice Embeddings.Guohua Wu - 2002 - Journal of Symbolic Logic 67 (3):1055-1064.
    Say that (a, d) is an isolation pair if a is a c.e. degree, d is a d.c.e. degree, a < d and a bounds all c.e. degrees below d. We prove that there are an isolation pair (a, d) and a c.e. degree c such that c is incomparable with a, d, and c cups d to o', caps a to o. Thus, {o, c, d, o'} is a diamond embedding, which was first proved by Downey in [9]. Furthermore, (...)

    Bi-Isolation in the D.C.E. Degrees.Guohua Wu - 2004 - Journal of Symbolic Logic 69 (2):409 - 420.
    In this paper, we study the bi-isolation phenomena in the d.c.e. degrees and prove that there are c.e. degrees c₁ < c₂ and a d.c.e. degree d ∈ (c₁, c₂) such that (c₁, d) and (d, c₂) contain no c.e. degrees. Thus, the c.e. degrees between c₁ and c₂ are all incomparable with d. We also show that there are d.c.e. degrees d₁ < d₂ such that (d₁, d₂) contains a unique c.e. degree.

    Quasi-Complements of the Cappable Degrees.Guohua Wu - 2004 - Mathematical Logic Quarterly 50 (2):189.
    Say that a nonzero c. e. degree b is a quasi-complement of a c. e. degree a if a ∩ b = 0 and a ∪ b is high. It is well-known that each cappable degree has a high quasi-complement. However, by the existence of the almost deep degrees, there are nonzero cappable degrees having no low quasi-complements. In this paper, we prove that any nonzero cappable degree has a low2 quasi-complement.

    Bias, Structure, and Injustice: A Reply to Haslanger.Robin Zheng - 2018 - Feminist Philosophy Quarterly 4 (1):1-30.
    Sally Haslanger has recently argued that philosophical focus on implicit bias is overly individualist, since social inequalities are best explained in terms of social structures rather than the actions and attitudes of individuals. I argue that questions of individual responsibility and implicit bias, properly understood, do constitute an important part of addressing structural injustice, and I propose an alternative conception of social structure according to which implicit biases are themselves best understood as a special type of structure.

  13. The Potential of Using Quantum Theory to Build Models of Cognition.Zheng Wang, Jerome R. Busemeyer, Harald Atmanspacher & Emmanuel M. Pothos - 2013 - Topics in Cognitive Science 5 (4):672-688.
    Quantum cognition research applies abstract, mathematical principles of quantum theory to inquiries in cognitive science. It differs fundamentally from alternative speculations about quantum brain processes. This topic presents new developments within this research program. In the introduction to this topic, we try to answer three questions: Why apply quantum concepts to human cognition? How is quantum cognitive modeling different from traditional cognitive modeling? What cognitive processes have been modeled using a quantum account? In addition, a brief introduction to quantum probability (...)

  15. What is My Role in Changing the System? A New Model of Responsibility for Structural Injustice.Robin Zheng - 2018 - Ethical Theory and Moral Practice 21 (4):869-885.
    What responsibility do individuals bear for structural injustice? Iris Marion Young has offered the most fully developed account to date, the Social Connections Model. She argues that we all bear responsibility because we each causally contribute to structural processes that produce injustice. My aim in this article is to motivate and defend an alternative account that improves on Young’s model by addressing five fundamental challenges faced by any such theory. The core idea of what I call the “Role-Ideal Model” is (...)

    A Quantum Question Order Model Supported by Empirical Tests of an A Priori and Precise Prediction.Zheng Wang & Jerome R. Busemeyer - 2013 - Topics in Cognitive Science 5 (4):689-710.
    Question order effects are commonly observed in self-report measures of judgment and attitude. This article develops a quantum question order model (the QQ model) to account for four types of question order effects observed in literature. First, the postulates of the QQ model are presented. Second, an a priori, parameter-free, and precise prediction, called the QQ equality, is derived from these mathematical principles, and six empirical data sets are used to test the prediction. Third, a new index is derived from (...)

    What Kind of Responsibility Do We Have for Fighting Injustice? A Moral-Theoretic Perspective on the Social Connections Model.Robin Zheng - 2019 - Critical Horizons 20 (2):109-126.
    Iris Marion Young’s influential Social Connections Model of responsibility offers a compelling approach to theorizing structural injustice. However, the precise nature of the kind of responsibility modelled by the SCM, along with its relationship to the liability model, has remained unclear. I offer a reading of Young that takes the difference between the liability model and the SCM to be an instance of a more longstanding distinction in the literature on moral responsibility: attributability vs. accountability. I show that interpreting the (...)

  18. Why Yellow Fever Isn't Flattering: A Case Against Racial Fetishes.Zheng Robin - 2016 - Journal of the American Philosophical Association 2 (3):400-419.
    Most discussions of racial fetish center on the question of whether it is caused by negative racial stereotypes. In this paper I adopt a different strategy, one that begins with the experiences of those targeted by racial fetish rather than those who possess it; that is, I shift focus away from the origins of racial fetishes to their effects as a social phenomenon in a racially stratified world. I examine the case of preferences for Asian women, also known as ‘yellow (...)

    This chapter distinguishes between two concepts of moral responsibility. We are responsible for our actions in the first sense only when those actions reflect our identities as moral agents, i.e. when they are attributable to us. We are responsible in the second sense when it is appropriate for others to enforce certain expectations and demands on those actions, i.e. to hold us accountable for them. This distinction allows for an account of moral responsibility for implicit bias, defended here, on which (...)

    Will Creative Employees Always Make Trouble? Investigating the Roles of Moral Identity and Moral Disengagement.Xiaoming Zheng, Xin Qin, Xin Liu & Hui Liao - 2019 - Journal of Business Ethics 157 (3):653-672.
    Recent research has uncovered the dark side of creativity by finding that creative individuals are more likely to engage in unethical behavior. However, we argue that not all creative individuals make trouble. Using moral self-regulation theory as our overarching theoretical framework, we examine individuals’ moral identity as a boundary condition and moral disengagement as a mediating mechanism to explain when and how individual creativity is associated with workplace deviant behavior. We conducted two field studies using multi-source data to test our (...)

    An Improved Squirrel Search Algorithm for Optimization.Tongyi Zheng & Weili Luo - 2019 - Complexity 2019:1-31.
    Squirrel search algorithm is a new biological-inspired optimization algorithm, which has been proved to be more effective for solving unimodal, multimodal, and multidimensional optimization problems. However, similar to other swarm intelligence-based algorithms, SSA also has its own disadvantages. In order to get better global convergence ability, an improved version of SSA called ISSA is proposed in this paper. Firstly, an adaptive strategy of predator presence probability is proposed to balance the exploration and exploitation capabilities of the algorithm. Secondly, a normal (...)

    A Job for Philosophers: Causality, Responsibility, and Explaining Social Inequality.Robin Zheng - 2018 - Dialogue 57 (2):323-351.
    People disagree about the causes of social inequality and how to most effectively intervene in them. These may seem like empirical questions for social scientists, not philosophers. However, causal explanation itself depends on broadly normative commitments. From this it follows that (moral) philosophers have an important role to play in determining those causal explanations. I examine the case of causal explanations of poverty to demonstrate these claims. In short, philosophers who work to reshape our moral expectations also work, on the (...)

    Decision Optimization of Low-Carbon Dual-Channel Supply Chain of Auto Parts Based on Smart City Architecture.Zheng Liu, Bin Hu, Bangtong Huang, Lingling Lang, Hangxin Guo & Yuanjun Zhao - 2020 - Complexity 2020:1-14.
    Affected by the Internet, computer, information technology, etc., building a smart city has become a key task of socialist construction work. The smart city has always regarded green and low-carbon development as one of the goals, and the carbon emissions of the auto parts industry cannot be ignored, so we should carry out energy conservation and emission reduction. With the rapid development of the domestic auto parts industry, the number of car ownership has increased dramatically, producing more and more CO2 (...)

    Moral Degradation, Business Ethics, and Corporate Social Responsibility in a Transitional Economy.Qinqin Zheng, Yadong Luo & Stephanie Lu Wang - 2014 - Journal of Business Ethics 120 (3):405-421.
    This article theoretically proposes and empirically verifies an understudied issue in the business ethics and corporate social responsibility literature—how moral degradation in a society influences the relationship between BE or CSR and firm performance. Building on strategic choice theory, we propose that both BE and CSR become more important in enhancing business success when the perceived MD is heightened. Our analysis of 300 firms operating in China statistically confirms our hypotheses: first, under high MD, firms’ engagement in CSR results in (...)

    Interpretational Paradox, Implicit Normativity, and Human Nature: Revisiting Weakness of Will From a Perspective of Comparative Philosophy.Yujian Zheng - 2017 - Dao: A Journal of Comparative Philosophy 16 (2):145-163.
    This essay critiques or engages a wide range of existing works on the ancient and well-contested issue of weakness of will, from a new perspective of comparative philosophy combined with a focus on a largely neglected Davidsonian paradox of irrationality. It aims at revealing the interplay between the descriptive and the normative in the very notion of critical interpretation, as well as a special relation between holding-true and making-true which helps to explain the non-accidentalness of the descriptive coat of the (...)

    The Mediating Role of Moral Elevation in Cause-Related Marketing: A Moral Psychological Perspective.Ling Zheng, Yunxia Zhu & Ruochen Jiang - 2019 - Journal of Business Ethics 156 (2):439-454.
    With the high frequency and intensity of worldwide disasters, cause-related marketing campaigns with sudden disasters are becoming increasingly popular. However, little is known about whether and how cause acuteness may influence consumer attitudes. This research aims to extend this research area through investigating the relationship between cause acuteness and consumer attitudes toward the product, as well as its underlying mechanism and boundary conditions. Based on a moral psychology perspective, we propose a theoretical model focusing on the mediating role of moral (...)

    An Almost-Universal Cupping Degree.Jiang Liu & Guohua Wu - 2011 - Journal of Symbolic Logic 76 (4):1137-1152.
    Say that an incomplete d.r.e. degree has almost universal cupping property, if it cups all the r.e. degrees not below it to 0′. In this paper, we construct such a degree d, with all the r.e. degrees not cupping d to 0′ bounded by some r.e. degree strictly below d. The construction itself is an interesting 0″′ argument and this new structural property can be used to study final segments of various degree structures in the Ershov hierarchy.

    Bounding Computably Enumerable Degrees in the Ershov Hierarchy.Angsheng Li, Guohua Wu & Yue Yang - 2006 - Annals of Pure and Applied Logic 141 (1):79-88.
    Lachlan observed that any nonzero d.c.e. degree bounds a nonzero c.e. degree. In this paper, we study the c.e. predecessors of d.c.e. degrees, and prove that given a nonzero d.c.e. degree , there is a c.e. degree below and a high d.c.e. degree such that bounds all the c.e. degrees below . This result gives a unified approach to some seemingly unrelated results. In particular, it has the following two known theorems as corollaries: there is a low c.e. degree isolating (...)

    Is Husserl a Conceptualist? Re-reading Husserl’s Sixth Logical Investigation.Pirui Zheng - 2019 - Husserl Studies 35 (3):249-263.
    Whether Husserl is a conceptualist has been heatedly debated among contemporary Husserl scholars. The present article intends to join the debate by asking the question of how, in the Husserlian context, intuitive acts fulfill signitive ones. On the one hand, those who take Husserl to be a conceptualist hold the content-identity theory, arguing that intuitive act and signitive act have the same content, so that the former can fulfill the latter. On the other hand, the non-conceptualists defend the object-identity theory (...)

    Corporate Recidivism in Emerging Economies.Qinqin Zheng & Rosa Chun - 2017 - Business Ethics: A European Review 26 (1):63-79.
    Prior research on corporate misconduct pays extensive attention to single misconduct behaviors. However, little research has addressed recidivism – the repeated behaviors of corporate misconduct. Based on institutional theory and using the context of emerging economies where recidivism plays a considerable role, we propose the path dependency of corporate recidivism and suggest that three influential factors exist: internal preconditioning, inter-organizational imitation, and the prevailing external evaluation. Our event history analysis of 1,036 listed companies in China over the period 2001–2008 statistically (...)

    Precarity is a Feminist Issue: Gender and Contingent Labor in the Academy.Robin Zheng - 2018 - Hypatia 33 (2):235-255.
    Feminist philosophers have challenged a wide range of gender injustices in professional philosophy. However, the problem of precarity, that is, the increasing numbers of contingent faculty who cannot find permanent employment, has received scarcely any attention. What explains this oversight? In this article, I argue, first, that academics are held in the grips of an ideology that diverts attention away from the structural conditions of precarity, and second, that the gendered dimensions of such an ideology have been overlooked.

    Technology, Capabilities and Critical Perspectives: What Can Critical Theory Contribute to Sen’s Capability Approach? [REVIEW]Yingqin Zheng & Bernd Carsten Stahl - 2011 - Ethics and Information Technology 13 (2):69-80.
    This paper explores what insights can be drawn from critical theory to enrich and strengthen Sen’s capability approach in relation to technology and human development. The two theories share some important commonalities: both are concerned with the pursuit of “a good life”; both are normative theories rooted in ethics and meant to make a difference, and both are interested in democracy. The paper provides a brief overview of both schools of thought and their applications to technology and human development. Three (...)

    An Anonymous Authentication Scheme in VANETs of Smart City Based on Certificateless Group Signature.Yuanpan Zheng, Guangyu Chen & Liguan Guo - 2020 - Complexity 2020:1-7.
    With the change of the network communication environment in vehicular ad hoc networks of a smart city, vehicles may encounter security threats such as eavesdropping, positioning, and tracking, so appropriate anonymity protection is required. Based on the certificateless cryptosystem and group signature ideas, this paper proposes a certificateless group signature anonymous authentication scheme for the VANETs of a smart city. In this scheme, it can implement the process of adding, signing, verifying, and revoking group members only by simple multiplication of (...)

    Jump Operator and Yates Degrees.Guohua Wu - 2006 - Journal of Symbolic Logic 71 (1):252 - 264.
    In [9]. Yates proved the existence of a Turing degree a such that 0. 0′ are the only c.e. degrees comparable with it. By Slaman and Steel [7], every degree below 0′ has a 1-generic complement, and as a consequence. Yates degrees can be 1-generic, and hence can be low. In this paper, we prove that Yates degrees occur in every jump class.

    1-Generic Splittings of Computably Enumerable Degrees.Guohua Wu - 2006 - Annals of Pure and Applied Logic 138 (1):211-219.
    Say a set Gω is 1-generic if for any eω, there is a string σG such that {e}σ↓ or τσ↑). It is known that can be split into two 1-generic degrees. In this paper, we generalize this and prove that any nonzero computably enumerable degree can be split into two 1-generic degrees. As a corollary, no two computably enumerable degrees bound the same class of 1-generic degrees.
