Reinforcing ethical decision making through corporate culture.Al Y. S.Chen,Roby B. Sawyers &Paul F. Williams -1997 -Journal of Business Ethics 16 (8):855-865.detailsBehaving ethically depends on the ability to recognize that ethical issues exist, to see from an ethical point of view. This ability to see and respond ethically may be related more to attributes of corporate culture than to attributes of individual employees. Efforts to increase ethical standards and decrease pressure to behave unethically should therefore concentrate on the organization and its culture. The purpose of this paper is to discuss how total quality (TQ) techniques can facilitate the development of a (...) cooperative corporate culture that promotes and encourages ethical behavior throughout an organization.

Thomas Kuhn‘s Latest Notion of Incommensurability.XiangChen -1997 -Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 28 (2):257-273.detailsTo correct the misconception that incommensurability implies incomparability, Kuhn lately develops a new interpretation of incommensurability. This includes a linguistic theory of scientific revolutions (the theory of kinds), a cognitive exploration of the language learning process (the analogy of bilingualism), and an epistemological discussion on the rationality of scientific development (the evolutionary epistemology). My focus in this paper is to review Kuhn's effort in eliminating relativism, highlighting both the insights and the difficulties of his new version of incommensurability . Finally (...) I suggest that some of Kuhn's difficulties can be overcome by adopting a concept of rationality that filly appreciates the important role of instruments in the development of science. (shrink)
Optimization of IoT-Based Motion Intelligence Monitoring System.Jian Qiao,Zhendong Zhang &EnqingChen -2021 -Complexity 2021:1-10.detailsWe design and implement an intelligent IoT-based motion monitoring system to realize the monitoring of three important parameters, namely, the type of movement, the number of movements, and the period of movement in physical activities, and optimize the system to support the simultaneous use by multiple users. Considering the motion monitoring scenario for smart fit, the framework of an IoT-based motion monitoring system is proposed. The framework contains components such as active acquisition nodes, wireless access points, data processing servers, and (...) terminals. In terms of algorithm optimization, research related to active pattern recognition and periodic calculation methods is conducted. For active pattern recognition, two types of classification algorithms with different complexity are proposed based on Support Vector Machine and deep neural networks, respectively, to adapt to scenarios with different computational capabilities. For period calculation, a method based on over-zero detection and wavelet transform is proposed to count the number of actions and calculate the period of each action. In 100 times action cycle calculation experiments, the count statistic calculation method achieves 100% calculation accuracy and the active cycle calculation results are close to the real value, which proves the effectiveness of the cycle calculation method. The system provides a multiuser-oriented communication method and realizes accurate and reliable human movement monitoring, which has a wide application prospect in the fields of physical education and rehabilitation training.

Continuity through revolutions: A frame-based account of conceptual change during scientific revolutions.XiangChen &Peter Barker -2000 -Philosophy of Science 67 (3):223.detailsIn this paper we examine the pattern of conceptual change during scientific revolutions by using methods from cognitive psychology. We show that the changes characteristic of scientific revolutions, especially taxonomic changes, can occur in a continuous manner. Using the frame model of concept representation to capture structural relations within concepts and the direct links between concept and taxonomy, we develop an account of conceptual change in science that more adequately reflects the current understanding that episodes like the Copernican revolution are (...) not always abrupt. When concepts are represented by frames, the transformation from one taxonomy to another can be achieved in a piecemeal fashion not preconditioned by a crisis stage, and a new taxonomy can arise naturally out of the old frame instead of emerging separately from the existing conceptual system. This cognitive mechanism of continuous change demonstrates the constructive roles of anomaly and incommensurability in promoting the progress of science. (shrink)
The Cognitive Structure of Scientific Revolutions.Hanne Andersen,Peter Barker &XiangChen -2006 - New York: Cambridge University Press. Edited by Peter Barker & Xiang Chen.detailsThomas Kuhn's Structure of Scientific Revolutions became the most widely read book about science in the twentieth century. His terms 'paradigm' and 'scientific revolution' entered everyday speech, but they remain controversial. In the second half of the twentieth century, the new field of cognitive science combined empirical psychology, computer science, and neuroscience. In this book, the theories of concepts developed by cognitive scientists are used to evaluate and extend Kuhn's most influential ideas. Based on case studies of the Copernican revolution, (...) the discovery of nuclear fission, and an elaboration of Kuhn's famous 'ducks and geese' example of concept learning, this volume, first published in 2006, offers accounts of the nature of normal and revolutionary science, the function of anomalies, and the nature of incommensurability.

Motivational profiles of kindergarten teachers in minority areas of China and their association with outcomes.Dasheng Shi,Mengmeng Zhang,YeChen,Ruining Jin &Xiantong Yang -2022 -Frontiers in Psychology 13.detailsAcademic discourses regarding teacher motivation have been on-going for decades for those who teach in ethnic minority areas. Yet research findings failed to provide a consistent conclusion regarding if kindergarten teachers’ motivation pattern would vary based on a case-to-case scenario. Therefore, further studies are needed to probe the motivation patterns among this population. The study firstly examined kindergarten teachers’ motivational profiles based on Expectancy Value Theory, and then examined how teachers’ motivation related to outcome variables. Participants included 1,199 kindergarten teachers (...) from ethnic minority areas in China. Latent profile analysis identified three motivation profiles for teachers: low value-high cost, moderate all, and high value-low cost. Teacher with different motivation profiles had significant differences in work engagement, workplace wellbeing, and retention intention. In addition, chain mediation analysis revealed that work engagement and workplace wellbeing mediated the relationship between motivation profiles and retention intention. The implications of the findings for study are discussed. (shrink)
Compensatory Ethics.Chen-Bo Zhong,Gillian Ku,Robert B. Lount &J. Keith Murnighan -2010 -Journal of Business Ethics 92 (3):323-339.detailsSeveral theories, both ancient and recent, suggest that having the time to contemplate a decision should increase moral awareness and the likelihood of ethical choices. Our findings indicated just the opposite: greater time for deliberation led to less ethical decisions. Post-hoc analyses and a followup experiment suggested that decision makers act as if their previous choices have created or lost moral credentials: after an ethical first choice, people acted significantly less ethically in their subsequent choice but after an unethical first (...) choice, people acted significantly more ethically in their subsequent choice. These findings provide the basis for a model of compensatory ethics. (shrink)
Object and event concepts: A cognitive mechanism of incommensurability.XiangChen -2003 -Philosophy of Science 70 (5):962-974.detailsIn this paper I examine a cognitive mechanism of incommensurability. Using the frame model of concept representation to capture structural relations within concepts, I reveal an ontological difference between object and event concepts: the former are spatial but the latter temporal. Experiments from cognitive sciences further demonstrate that the mind treats object and event concepts differently. Thus, incommensurability can occur in conceptual change across different ontological categories. I use a historical case to illustrate how the ontological difference between an object (...) and an event concept actually caused incommensurability in the context of nineteenth‐century optics. The cognitive and historical analyses indicate that incommensurability can be a local phenomenon and does not necessarily imply incomparability. (shrink)
The concept of fate in mencius.NingChen -1997 -Philosophy East and West 47 (4):495-520.detailsMencius, who often spoke of ming in different senses among which only one can be taken as fate, upheld two doctrines of fate--moral determinism and blind, unalterable fate--but he was prone to apply the former to collective entities, and the latter to individual persons. This bi-level distinction, which is at variance with the non-distinction in both Moism and Taoism, exercised a profound influence upon the minds of later Confucians.
The object bias and the study of scientific revolutions: Lessons from developmental psychology.XiangChen -2007 -Philosophical Psychology 20 (4):479 – 503.detailsI propose a new perspective on the study of scientific revolutions. This is a transformation from an object-only perspective to an ontological perspective that properly treats objects and processes as distinct kinds. I begin my analysis by identifying an object bias in the study of scientific revolutions, where it takes the form of representing scientific revolutions as changes in classification of physical objects. I further explore the origins of this object bias. Findings from developmental psychology indicate that children cannot distinguish (...) processes from objects until the age of 7, but they have already developed a core system of object knowledge as early as 4 months of age. The persistence of this core system is responsible for the object bias among mature adults, i.e., the tendency to apply knowledge of physical objects to temporal processes. In light of the distinction between physical objects and temporal processes, I redraw the picture of the Copernican revolution. Rather than seeing it as a taxonomic shift from a geocentric to a heliocentric cosmology, we should understand it as a transformation from a conceptual system that was built around an object concept to one that was built around a process concept.

Transforming temporal knowledge: Conceptual change between event concepts.XiangChen -2005 -Perspectives on Science 13 (1):49-73.details: This paper offers a preliminary analysis of conceptual change between event concepts. It begins with a brief review of the major findings of cognitive studies on event knowledge. The script model proposed by Schank and Abelson was the first attempt to represent event knowledge. Subsequent cognitive studies indicated that event knowledge is organized in the form of dimensional organizations in which temporally successive actions are related causally. This paper proposes a frame representation to capture and outline the internal structure (...) of event concepts, in particular, their causal connections. The frame representation offers an effective method to analyze the relations between event concepts, and to expose the unique cognitive mechanisms behind conceptual change involved event concepts. Finally this paper shows that the frame representation of event concepts is instrumental to understanding an important historical episode of conceptual change in the context of nineteenth-century optics.

Kuhn's mature philosophy of science and cognitive psychology.Hanne Andersen,Peter Barker &XiangChen -1996 -Philosophical Psychology 9 (3):347 – 363.detailsDrawing on the results of modem psychology and cognitive science we suggest that the traditional theory of concepts is no longer tenable, and that the alternative account proposed by Kuhn may now be seen to have independent empirical support quite apart from its success as part of an account of scientific change. We suggest that these mechanisms can also be understood as special cases of general cognitive structures revealed by cognitive science. Against this background, incommensurability is not an insurmountable obstacle (...) to accepting Kuhn's position, as many philosophers of science still believe. Rather it becomes a natural consequence of cognitive structures that appear in all human beings. (shrink)
The Decoherent Arrow of Time and the Entanglement Past Hypothesis.Jim Al-Khalili &Eddy KemingChen -2024 -Foundations of Physics 54 (49).detailsIf an asymmetry in time does not arise from the fundamental dynamical laws of physics, it may be found in special boundary conditions. The argument normally goes that since thermodynamic entropy in the past is lower than in the future according to the Second Law of Thermodynamics, then tracing this back to the time around the Big Bang means the universe must have started off in a state of very low thermodynamic entropy: the Thermodynamic Past Hypothesis. In this paper, we (...) consider another boundary condition that plays a similar role, but for the decoherent arrow of time, i.e. the subsystems of the universe are more mixed in the future than in the past. According to what we call the Entanglement Past Hypothesis, the initial quantum state of the universe had very low entanglement entropy. We clarify the content of the Entanglement Past Hypothesis, compare it with the Thermodynamic Past Hypothesis, and identify some challenges and open questions for future research. (shrink)
Rethinking the phenomenological meaningfulness of bodily presence and absence in online education.Yulong Li &ZhenChen -2025 -Filosofiya osvity Philosophy of Education 30 (2):110-123.detailsOnline education was once considered a convenient and flexible educational channel. However, COVID-19 forced most teachers and students to have no other option but to move lessons online. Academic publications on online presence can be categorised into two independent fields: theoretical discussions and practical frameworks for improving online presence. Among these publications, some authors are holding pessimistic attitudes towards the idea of online presence. Some of them, following Heideggerian Gelassenheit, argue that online education is more or less a result of (...) participants’ exhibition of controlled and judgemental performances due to its disembodiment, which freezes the reality and is devoted to calculative thinking. Others, following the Levinasian phenomenology of the face, claim that online education, with the screen as the barrier, jeopardises the embodied sensitivity and responsiveness of teachers’ ethical attuning to students. To negotiate with these authors, we would like to remind them of its possibility. Therefore, we draw on Merleau-Ponty’s phenomenology of embodiment to introduce an opinion confirming online presence in education. We then point out the danger of reducing learning to the state of being present in classes, whether bodily or virtually, by inviting readers to rethink “absence” as a concealed side of presence and to confirm the roles of absence and presence in co-constructing a person’s perception of things. We thus emphasise the importance of teachers’ and students’ intentionality to teach or to learn, which determines the effects of online education. Finally, this study concludes with a post-digital view that beckons us to transcend the current debate of teaching online or offline, recognising a blurred boundary between the virtual and bricks-and-mortar modes of education.

Jokes can fail to be funny because they are immoral: The incompatibility of emotions.Dong An &KaiyuanChen -2021 -Philosophical Psychology 34 (3):374-396.detailsJustin D’Arms and Daniel Jacobson have argued that to evaluate the funniness of a joke based on the consideration of whether it is morally appropriate to feel amused commits the “moralistic fallacy.” We offer a new and empirically informed reply. We argue that there is a way to take morality into consideration without committing this fallacy, that is, it is legitimate to say that for some people, witty but immoral jokes can fail to be funny because they are immoral. In (...) our account, one has an intramural moral reason not to feel amused if one focuses on the moral feature itself of a joke rather than the moral consequence implied in one’s reaction to the joke. When one judges a joke as not funny because of the intramural moral reason, one is in a negative emotional state with high arousal, for example, moral disgust or anger. This state is psychologically incompatible with amusement. That one has an intramural reason not to feel amused thus implies that one does not have a reason to feel amused. Moral consideration thus plays an indirect and appropriate role in the evaluation of the funniness of a joke. (shrink)
Empirical content and rational constraint.Cheryl K.Chen -2006 -Inquiry: An Interdisciplinary Journal of Philosophy 49 (3):242 – 264.detailsIt is often thought that epistemic relations between experience and belief make it possible for our beliefs to be about or "directed towards" the empirical world. I focus on an influential attempt by John McDowell to defend a view along these lines. According to McDowell, unless experiences are the sorts of things that can be our reasons for holding beliefs, our beliefs would not be "answerable" to the facts they purportedly represent, and so would lack all empirical content. I argue (...) that there is no intelligible conception of what it is for beliefs to be answerable to the facts that supports McDowell's claim that our empirical beliefs must be justified by experience.

Defensive medicine or economically motivated corruption? A confucian reflection on physician care in china today.Xiao-YangChen -2007 -Journal of Medicine and Philosophy 32 (6):635 – 648.detailsIn contemporary China, physicians tend to require more diagnostic work-ups and prescribe more expensive medications than are clearly medically indicated. These practices have been interpreted as defensive medicine in response to a rising threat of potential medical malpractice lawsuits. After outlining recent changes in Chinese malpractice law, this essay contends that the overuse of expensive diagnostic and therapeutic interventions cannot be attributed to malpractice concerns alone. These practice patterns are due as well, if not primarily, to the corruption of medical (...) decision-making by physicians being motivated to earn supplementary income, given the constraints of an ill-structured governmental policy by the over-use of expensive diagnostic and therapeutic interventions. To respond to these difficulties of Chinese health care policy, China will need not only to reform the particular policies that encourage these behaviors, but also to nurture a moral understanding that can place the pursuit of profit within the pursuit of virtue. This can be done by drawing on Confucian moral resources that integrate the pursuit of profit within an appreciation of benevolence. It is this Confucian moral account that can formulate a medical care policy suitable to China's contemporary market economy. (shrink)
Clinical bioethics in china: The challenge of entering a market economy.Xiao-YangChen -2006 -Journal of Medicine and Philosophy 31 (1):7 – 12.detailsOver the last quarter-century, China has experienced dramatic changes associated with its development of a market economy. The character of clinical practice is also profoundly influenced by the ways in which reimbursement scales are established in public hospitals. The market distortions that lead to the over-prescription of drugs and the medically unindicated use of more expensive drugs and more costly high-technology diagnostic and therapeutic interventions create the most significant threat to patients. The payment of red packets represents a black-market attempt (...) to circumvent the non-market constraint on physicians' fees for services. These economic and practice pattern changes are taking place as China and many Pacific Rim societies are reconsidering the moral foundations of their professional ethics and their bioethics. The integrity of the medical profession and the trust of patients in physicians can only be restored and protected if the distorting forces of contemporary public policy are altered. (shrink)
Putting it Together, Together.Chen Zheng &Barbara Tversky -2024 -Cognitive Science 48 (2):e13405.detailsPeople are not as fast or as strong as many other creatures that evolved around us. What gives us an evolutionary advantage is working together to achieve common aims. Coordinating joint action begins at a tender age with such cooperative activities as alternating babbling and clapping games. Adult joint activities are far more complex and use multiple means of coordination. Joint action has attracted qualitative analyses by sociolinguists, cognitive scientists, and philosophers as well as empirical analyses and theories by cognitive (...) scientists. Here, we analyze how joint action is spontaneously coordinated from start to finish in a novel complex real‐life joint activity, assembling a piece of furniture, a task that captures the essentials of joint action, collaborators, things in the world, and communicative devices. Pairs of strangers assembled a TV cart from a stack of parts and a photo of the completed cart. Coordination prior to each assembly action was coded as explicit, using speech or gesture, or implicit, actions that both advanced the task and communicated the next step. Initial planning relied on explicit communication about structure, but not action nor division of labor, which were improvised. That served to establish a joint representation of the goal that informed actions and monitored progress. As assembly progressed, coordination was increasingly implicit, through actions alone. Joint action is a dynamic interplay of explicit and implicit signaling with respect to things in the world to coordinate ongoing progress, guided by a shared representation of the goal. (shrink)
Edgar Morin's paradigm of complexity and gödel's incompleteness theorem.Yi-ZhuangChen -2004 -World Futures 60 (5 & 6):421 – 431.detailsThis article shows that in two respects, Gödel's incompleteness theorem strongly supports the arguments of Edgar Morin's complexity paradigm. First, from the viewpoint of the content of Gödel's theorem, the latter justifies the basic view of complexity paradigm according to which knowledge is a dynamic, unfinished process, and develops by way of self-criticism and self-transcendence. Second, from the viewpoint of the proof procedure of Gödel's theorem, the latter confirms the complexity paradigm's circular line of inference through which is formed the (...) all-round knowledge of a concrete object.

Carrot or Stick? CSR and Firm Financial Performance.Chen Ma &Latif Yasir -2023 -Journal of Business Ethics 188 (2):349-365.detailsIn this study, we propose and test the relationship between CSR and firm financial performance, how this relationship differs between firms led by CEOs with political connections and those led by CEOs without political connections, and how this relationship differs between state-owned firms and nonstate-owned firms. Based on a sample of 1645 Chinese listed firms during the period 2011 and 2020 (inclusive), we find that CSR has an inverted U-shaped relationship with firm financial performance. As the level of CSR increases (...) from slight to moderate, CSR is positively related to firm performance; as the level of CSR increases from moderate to great, CSR is negatively related to firm financial performance. Additionally, we find that this inverted U-shaped relationship differs between firms led by CEOs with political connections and those led by CEOs without political connections and differs between state-owned firms and nonstate-owned firms. That is, both the synergic effect (positive effect) of CSR on firm financial performance when the level of CSR is low and the competitive effect (negative effect) of CSR on firm financial performance when the CSR is high are more pronounced for firms led by CEOs without political connections and nonstate-owned firms than for firms led by CEOs with political connections and state-owned firms. The theoretical and managerial implications of these findings are discussed. (shrink)
Promoting Cooperation in an Unequal World: Experimental Evidence on the Role of Transparency and Punishment.Jingnan CeciliaChen,John D’Attoma,Miguel A. Fonseca &Antoine Malézieux -forthcoming -Journal of Business Ethics:1-20.detailsAcross two studies, we examine the role of transparency and peer punishment in promoting cooperation and addressing economic inequality in public good contributions. With global inequality rising and the wealthiest few amassing a greater share of resources, its impact on social cohesion and business environments is increasingly significant. Financial secrecy further compounds these issues by allowing for income and wealth concealment at both societal and organizational levels. Our experimental findings reveal that transparency paired with peer punishment significantly boosts cooperation, particularly (...) among advantaged individuals. In contrast, peer punishment alone proves insufficient to mitigate the adverse effects of inequality without the support of transparency. These results underscore the need for ethical governance structures that incorporate transparency, fairness, and accountability—principles essential for organizations committed to fostering trust and social responsibility in unequal settings.

Are Donors Watching? Nonprofit Rating Availability and Pay-to-Performance Sensitivity.Chen Zhao &Richard Dull -2025 -Journal of Business Ethics 197 (4):855-872.detailsCEO compensation by nonprofit organizations is controversial. Higher-qualified CEOs should be compensated more than lesser-qualified individuals because of better performance regarding organizational goals and missions. Alternatively, an ethical issue may exist if CEOs are overcompensated resulting in a negative impact on the operations of their organizations. Donors have the incentive to monitor nonprofit organizations, but their role is limited to their ability to acquire nonprofit organization information. However, charity rating agencies make information more accessible and understandable, thus reducing information asymmetry (...) between donors and nonprofit organizations. This study examines whether charity rating availability is associated with negative pay-to-performance sensitivity. Using a sample derived from the IRS Form 990 s and Charity Navigator ratings, this study provides evidence that rating availability is negatively related to pay-to-performance sensitivity in nonprofit organizations. Additional tests provide evidence that the overall rating score and its financial rating component are negatively associated with pay-to-performance sensitivity. (shrink)
Research on the issue of “evil” in Wang Yangming’s thought.LishengChen -2007 -Frontiers of Philosophy in China 2 (2):172-187.detailsWang Yangming’s discussions concerning evil mainly appear in two sets of texts, i.e., Chuanxilu 传习录 (Instructions for Practical Living) and gongyi 公移 (documents transferred to vertically unrelated departments). The former addresses evil in metaphysical terms, and the latter in social terms. These subtly different approaches show the nuance between self-cultivation and governance of others.
Advice classes of parameterized tractability.Liming Cai,JianerChen,Rodney G. Downey &Michael R.

For example, there are many problems for which the input consists of a graph and a positive integer.

Different ways in which the word of advice can be employed are considered, and it (...) is shown that the class FPT of tractable parameterized problems has interesting and natural internal structure.

On the parameterized complexity of short computation and factorization.Liming Cai,JianerChen,Rodney G. Downey &Michael R. Fellows -1997 -Archive for Mathematical Logic 36 (4-5):321-337.detailsA completeness theory for parameterized computational complexity has been studied in a series of recent papers, and has been shown to have many applications in diverse problem domains including familiar graph-theoretic problems, VLSI layout, games, computational biology, cryptography, and computational learning [ADF,BDHW,BFH, DEF,DF1-7,FHW,FK]. We here study the parameterized complexity of two kinds of problems: (1) problems concerning parameterized computations of Turing machines, such as determining whether a nondeterministic machine can reach an accept state in \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} (...) \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $k$\end{document} steps (the Short TM Computation Problem), and (2) problems concerning derivations and factorizations, such as determining whether a word \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $x$\end{document} can be derived in a grammar \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $G$\end{document} in \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $k$\end{document} steps, or whether a permutation has a factorization of length \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $k$\end{document} over a given set of generators. We show hardness and completeness for these problems for various levels of the \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $W$\end{document} hierarchy.
