A unifying causal framework for analyzing dataset shift-stable learning algorithms.Suchi Saria,BryantChen &Adarsh Subbaswamy -2022 -Journal of Causal Inference 10 (1):64-89.detailsRecent interest in the external validity of prediction models has produced many methods for finding predictive distributions that are invariant to dataset shifts and can be used for prediction in new, unseen environments. However, these methods consider different types of shifts and have been developed under disparate frameworks, making it difficult to theoretically analyze how solutions differ with respect to stability and accuracy. Taking a causal graphical view, we use a flexible graphical representation to express various types of dataset shifts. (...) Given a known graph of the data generating process, we show that all invariant distributions correspond to a causal hierarchy of graphical operators, which disable the edges in the graph that are responsible for the shifts. The hierarchy provides a common theoretical underpinning for understanding when and how stability to shifts can be achieved, and in what ways stable distributions can differ. We use it to establish conditions for minimax optimal performance across environments, and derive new algorithms that find optimal stable distributions. By using this new perspective, we empirically demonstrate that that there is a tradeoff between minimax and average performance. (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.

Is It Wrong to Eat Meat from Factory Farms? If So, Why?MarkBryant Budolfson -2015 - In Ben Bramble & Bob Fischer,The Moral Complexities of Eating Meat. New York, US: Oxford University Press. pp. 1-22.detailsMany philosophers endorse utilitarian arguments against eating meat along the lines of Peter Singer’s, while others endorse deontological arguments along the lines of Tom Regan’s. This chapter suggests that both types of arguments are too quick. Empirical reasons are outlined for thinking that when one eats meat, that doesn’t make a difference to animals in the way that it would have to for either type of argument to be sound—and this chapter argues that this is true notwithstanding recent “expected utility” (...) arguments to the contrary. The chapter then identifies a general puzzle: given that almost everything we do in modern society has some footprint of harm, how does one properly distinguish acts that are permissible among these from those that are not? The chapter explains why this is more difficult than it may initially appear, and it proposes a solution. (shrink)

The inefficacy objection to consequentialism and the problem with the expected consequences response.MarkBryant Budolfson -2019 -Philosophical Studies 176 (7):1711-1724.detailsCollective action problems lie behind many core issues in ethics and social philosophy—for example, whether an individual is required to vote, whether it is wrong to consume products that are produced in morally objectionable ways, and many others. In these cases, it matters greatly what we together do, but yet a single individual’s ‘non-cooperative’ choice seems to make no difference to the outcome and also seems to involve no violation of anyone’s rights. Here it is argued that—contrary to influential arguments (...) by Peter Singer, Alastair Norcross, Shelly Kagan, Derek Parfit, and Allan Gibbard—an appeal to the expected consequences of acts cannot deliver plausible verdicts on many of these cases, because individuals often have a probability of making a difference that is sufficiently small to ensure that ‘non-cooperation’ is the option with the greatest expected value, even when consequentialists themselves agree that ‘cooperation’ is required. In addition, an influential argument by Singer, Norcross, and Kagan is shown to be unsound for the claim that in the collective action situations at issue, the expected effect of one individual’s action equals the average effect of everyone’s similar actions. These results have general implications for normative theory, because they undermine the sort of consequentialist explanation of collective action cases that is initially attractive from many theoretical points of view, consequentialist and otherwise.

Does Self-Serving Leadership Hinder Team Creativity? A Moderated Dual-Path Model.Jian Peng,Zhen Wang &XiaoChen -2019 -Journal of Business Ethics 159 (2):419-433.detailsSelf-serving leadership is a form of unethical leadership behavior that has destructive effect on its targets and the overall organization. Adopting a social cognition perspective, this study expands our knowledge of its adverse effect and the way to mitigate the effect. Integrating two sub-theories of social cognition, we propose a theoretical model wherein self-serving leadership hinders team creativity through psychological safety as well as knowledge hiding, with task interdependence acting as a contextual condition. Results from a sample of 107 R&D (...) teams revealed that self-serving leadership not only reduced team psychological safety, but also induced team knowledge hiding, both of which ultimately affected team creativity. The presence of high task interdependence buffered the destructive effect of self-serving leadership on team creativity via team psychological safety as well as the indirect effect via knowledge hiding.

Non-cognitivism and rational inference.MarkBryant Budolfson -2011 -Philosophical Studies 153 (2):243 - 259.detailsNon-cognitivism might seem to offer a plausible account of evaluative judgments, at least on the assumption that there is a satisfactory solution to the Frege-Geach problem. However, Cian Dorr has argued that non-cognitivism remains implausible even assuming that the Frege-Geach problem can be solved, on the grounds that non-cognitivism still has to classify some paradigmatically rational inferences as irrational. Dorr's argument is ingenious and at first glance seems decisive. However, in this paper I will show that Dorr's argument equivocates between (...) two different notions of evidence, and that once this equivocation is noted there is no reason to doubt that non-cognitivism is consistent with the rationality of such inferences, at least if it is assumed that the Frege-Geach problem can be solved. In particular, I will show that non-cognitivists can endorse the same explanation of the rationality of such inferences that cognitivists should endorse, and that there is thus no need for non-cognitivists to offer any sort of idiosyncratic account of the epistemology of such cases, in contrast to what other commentators on Dorr's argument have thought.

The Associations among Moral Foundations, Political Ideology, and Social Issues: A Study of These Associations in an Asian Sample.I. J. Hsieh &Yung Y.Chen -2021 -Journal of Cognition and Culture 21 (1-2):138-151.detailsThis study examined the relationships among moral foundations, political ideology, and controversial social issues in an Asian culture. The study sample included 835 participants who completed a moral foundations questionnaire and three questions regarding attitudes toward social issues, and a political ideology questionnaire. Results indicated that binding foundations were associated conservative tendencies, and individualizing foundations were associated liberal tendencies. Also, participants who scored higher on Authority showed higher approval of the death penalty, and those scored higher on Purity showed lower (...) approval of the euthanasia. These results may provide a better understanding of the underlying differences for variations in opinions on social issues. Results also have implications for cultural differences in the associations among political ideology, social issues, and moral foundations. (shrink)
Orchestrating Multi-Agent Knowledge Ecosystems: The Role of Makerspaces.Jia-Lu Shi &Guo-HongChen -2022 -Frontiers in Psychology 13.detailsIn the knowledge economy, the process of knowledge sharing and creation for value co-creation frequently emerge in a multi-agent and multi-level system. It's important to consider the roles, functions, and possible interactive knowledge-based activities of key actors for ecological development. Makerspace as an initial stage of incubated platform plays the central and crucial roles of resource orchestrators and platform supporter. Less literature analyses the knowledge ecosystem embedded by makerspaces and considers the interactive process of civil society and natural environment. This (...) study constructs a multi-agent and multi-level knowledge ecosystem from macro, meso, and micro perspective based on Quintuple Helix theory and designs four evolutionary stages of knowledge orchestrating processes. This study finds that the symbiosis, co-evolution, interaction, and orchestration of multiple agents in the knowledge ecosystem should be merged with each other for value co-creation, which helps to take a systematic approach for policymakers, managers, and researchers.

Why the Standard Interpretation of Aldo Leopold’s Land Ethic is Mistaken.MarkBryant Budolfson -2014 -Environmental Ethics 36 (4):443-453.detailsThe standard interpretation of Aldo Leopold’s land ethic is that correct land management is whatever tends to preserve the integrity, stability, and beauty of the biotic community, of which we humans are merely a small part. From this interpretation, it is a short step to interpreting Leopold as a sort of deep ecologist or radical environmentalist. However, this interpretation is based on a small number of quotations from Leopold taken out of context. Once these quotations are put into context, and (...) once the broader context of Leopold’s mature writings and his actions as a land manager are taken into account, it becomes clear that he is much closer to being an enlightened anthropocentrist than he is to being anything like a radical environmentalist. When properly understood, Leopold’s land ethic recognizes that fundamental human interests must be treated with the highest possible respect, and it emphasizes the incredible challenge and need for modesty in identifying the correct tradeoffs between lesser human interests and the interests of the broader biotic community.

Culture under Complex Perspective: A Classification for Traditional Chinese Cultural Elements Based on NLP and Complex Networks.Lin Qi,Yuwei Wang,JindongChen,Mengjie Liao &Jian Zhang -2021 -Complexity 2021:1-15.detailsThe cultural element is the minimum unit of a cultural system. The systematic categorizing, organizing, and retrieval of the traditional Chinese cultural elements are essential prerequisites for the realization of effective extracting and rational utilization, as well as the prerequisite for exploiting the contemporary value of the traditional Chinese culture. To build an objective, integrated, and reliable classification method and a system of traditional Chinese cultural elements, this study takes the text of Taiping Imperial Encyclopedia in Northern Song Dynasty as (...) the primary data source. The unsupervised word segmentation methods are used to detect Out-of-Vocabulary, and then the segmentation results by the THULAC tool with and without custom dictionary are compared. The TF-IDF algorithm is applied to extract the keywords of cultural elements and the Ochiia coefficient is introduced to create complex networks of traditional Chinese cultural elements. After analyzing the topological characteristics of the network, the community detection algorithm is used to identify the topics of cultural elements. Finally, a “Means-Ends” two-dimensional orthogonal classification system is established to categorize the topics. The results showed that the degree distribution in the complex network of Chinese traditional cultural elements is a scale-free network with γ = 2.28. The network shows a structure of community and hierarchy features. The top 12 communities have taken up to 91.77% of the scale of the networks. Those 12 topics of the traditional Chinese cultural elements are circularly distributed in the orthogonal system of cultural elements’ categorization. (shrink)
Catechol-O-Methyltransferase Gene Val158Met Polymorphism Moderates the Effect of Social Exclusion and Inclusion on Aggression in Men: Findings From a Mixed Experimental Design.Meiping Wang,PianChen,Hang Li,Andrew Haddon Kemp &Wenxin Zhang -2021 -Frontiers in Psychology 11.detailsAccumulating research has identified the interactive effects of catechol-O-methyltransferase gene Val158Met polymorphism and environmental factors on aggression. However, available evidence was mainly based upon correlational design, which yields mixed findings concerning who are more affected by environmental conditions and has been challenged for the low power of analyses on gene–environment interaction. Drawing on a mixed design, we scrutinized how COMT Val158Met polymorphism impacts on aggression, assessed by hostility, aggressive motivation, and aggressive behavior, under different social conditions in a sample of (...) 70 Chinese male undergraduate students. We found that both Val/Val homozygote and Met alleles carriers showed differences in the feelings of hostility and aggressive motivation under conditions of exclusion versus inclusion, but these differences were more pronounced for Met allele carriers. These findings implied that COMT Val158Met polymorphism did not respond to environmental stimuli in an all-or-none way and shed light on the importance of examining the gene–environment interaction using a mixed design.

Investigation on the influence of the brand image of higher educational institutions on satisfaction and customer lifetime value.Cheng-Cai Wang,Chin-TsuChen &Chun-FuChen -2012 -Educational Studies 38 (5):593-608.detailsThis study aimed to discuss the relationships among the brand image of universities (external variables), university satisfaction (mediating variables) and customer lifetime value (internal variables). The findings can serve as a reference for higher educational institutions in strengthening their advantages and overcoming their shortcomings, as well as for administrative decision-making. A questionnaire survey was conducted on university students in Taiwan, and 470 valid samples were retrieved. The data were analysed with structural equation modelling and multi-group analysis. The results showed that (...) brand image influences customer satisfaction, which in turn affects customer lifetime value. Satisfaction is a partial mediating variable between brand image and customer lifetime value. Multi-group analysis found that gender has no interfering effect between brand image and satisfaction, nor does it between satisfaction and customer lifetime value or between brand image and customer lifetime value.

Understanding Why Tourists Who Share Travel Photos Online Give More Positive Tourism Product Evaluation: Evidence From Chinese Tourists.Xiuyuan Tang,Yanping Gong,ChunyanChen,Suying Wang &PengfeiChen -2022 -Frontiers in Psychology 13.detailsThis study tested a conceptual model in which photo-sharing behavior during travel elicits tourists’ emotional state, and in turn improves evaluation of the tourism product. The research results in the context of tourist attractions and restaurants provide support for the proposed model. Specifically, tourists’ photo-sharing behavior was significantly associated with more positive product evaluation, both directly and indirectly via the emotion of pleasure. These associations were stronger when the interdependent self-construers had good social experience. The results provide practical guidance for (...) marketers to developing marketing strategy.

We established the normal values of CHEPs parameters in Chinese adults, optimized the test technique, and determined its reproducibility.Methods: We recruited 151 healthy adults. CHEPs was performed on the right forearm to determine the optimal number of stimuli, and then conducted at different sites to establish normal values, determine the effects of demographic characteristics and baseline temperature, and assess the short- and long-term reproducibility. N2 latency/height varied with age (...) and sex, while P2 latency/height and N2–P2 amplitude varied with age. The optimal number of stimuli was three.Results: N2 latency/height and P2 latency/height decreased and N2–P2 amplitude and visual analog scale score increased with increased baseline temperature. CHEPs parameters did not differ with time.Conclusion: We established normal CHEPs values in Chinese adults. We found that CHEPs parameters changed with baseline temperature and that the short- and long-term test reproducibility were satisfactory. (shrink)
Promoting cross‐cultural awareness and understanding: incorporating ethnographic interviews in college EFL classes in Taiwan.Ya‐Chen Su -2008 -Educational Studies 34 (4):377-398.detailsThe emergence of the incorporation of culture into EFL education is a growing trend in Taiwan. The purpose of the study was to examine: the effects of the ethnographic interview project on Taiwanese students' cognitive development in understanding native English speakers and their cultures; changes in students' self‐awareness and understanding of both the target culture and their own; and students' perceptions of the ethnographic interview project employed in EFL college classes. Data were collected through pre–post questionnaires, oral and written reports, (...) classroom observation and interviews. Results indicated that participation in the ethnographic interview project helped facilitate the development of cross‐cultural awareness and communication skills by providing opportunities for students to gain insight into the values of target language countries, learn to view their own culture in new ways, increase their confidence in using English to communicate and view authentic communication as the goal of EFL learning. The majority of the participants saw the ethnographic interview project as an effective means of facilitating intercultural/interpersonal communication and understanding. (shrink)
Neuroanatomical Alterations in Patients With Tinnitus Before and After Sound Therapy: A Combined VBM and SCN Study.Xuan Wei,Han Lv,QianChen,Zhaodi Wang,Chunli Liu,Pengfei Zhao,Shusheng Gong,Zhenghan Yang &Zhenchang Wang -2021 -Frontiers in Human Neuroscience 14.detailsMany neuroanatomical alterations have been detected in patients with tinnitus in previous studies. However, little is known about the morphological and structural covariance network changes before and after long-term sound therapy. This study aimed to explore alterations in brain anatomical and SCN changes in patients with idiopathic tinnitus using voxel-based morphometry analysis 24 weeks before and after sound therapy. Thirty-three tinnitus patients underwent magnetic resonance imaging scans at baseline and after 24 weeks of sound therapy. Twenty-six age- and sex-matched healthy (...) control individuals also underwent two scans over a 24-week interval; 3.0T MRI and high-resolution 3D structural images were acquired with a 3D-BRAVO pulse sequence. Structural image data preprocessing was performed using the VBM8 toolbox. The Tinnitus Handicap Inventory score was assessed for the severity of tinnitus before and after treatment. Two-way mixed model analysis of variance and post hoc analyses were performed to determine differences between the two groups and between the two scans. Student-Newman-Keuls tests were used in the post hoc analysis. Interaction effects between the two groups and the two scans demonstrated significantly different gray matter volume in the right parahippocampus gyrus, right caudate, left superior temporal gyrus, left cuneus gyrus, and right calcarine gyrus; we found significantly decreased GM volume in the above five brain regions among the tinnitus patients before sound therapy compared to that in the HC group. The 24-week sound therapy group demonstrated significantly greater brain volume compared with the baseline group among these brain regions. We did not find significant differences in brain regions between the 24-week sound therapy and HC groups. The SCN results showed that the left superior temporal gyrus and left rolandic operculum were significantly different in nodal efficiency, nodal degree centrality, and nodal betweenness centrality after FDR correction. This study characterized the effect of sound therapy on brain GM volume, especially in the left superior temporal lobe. Notably, sound therapy had a normalizing effect on tinnitus patients. (shrink)

Children ASD Evaluation Through Joint Analysis of EEG and Eye-Tracking Recordings With Graph Convolution Network.Shasha Zhang,DanChen,Yunbo Tang &Lei Zhang -2021 -Frontiers in Human Neuroscience 15.detailsRecent advances in neuroscience indicate that analysis of bio-signals such as rest state electroencephalogram and eye-tracking data can provide more reliable evaluation of children autism spectrum disorder than traditional methods of behavior measurement relying on scales do. However, the effectiveness of the new approaches still lags behind the increasing requirement in clinical or educational practices as the “bio-marker” information carried by the bio-signal of a single-modality is likely insufficient or distorted. This study proposes an approach to joint analysis of EEG (...) and eye-tracking for children ASD evaluation. The approach focuses on deep fusion of the features in two modalities as no explicit correlations between the original bio-signals are available, which also limits the performance of existing methods along this direction. First, the synchronization measures, information entropy, and time-frequency features of the multi-channel EEG are derived. Then a random forest applies to the eye-tracking recordings of the same subjects to single out the most significant features. A graph convolutional network model then naturally fuses the two group of features to differentiate the children with ASD from the typically developed subjects. Experiments have been carried out on the two types of the bio-signals collected from 42 children. The results indicate that the proposed approach can achieve an accuracy of 95% in ASD detection, and strong correlations exist between the two bio-signals collected even asynchronously, in particular the EEG synchronization against the face related/joint attentions in terms of covariance.
