Reinforcement learning relies on the reward prediction error (RPE) signals conveyed by the midbrain dopamine system. Previous studies showed that dopamine plays an important role in both positive and negative reinforcement. However, whether various reinforcement processes will induce distinct learning signals is still unclear. In a probabilistic learning task, we examined RPE signals in different reinforcement types using an electrophysiology index, namely, the feedback-related negativity (FRN). Ninety-four participants were randomly assigned into four groups: base (no money incentive), positive reinforcement (presentation (...) of money rewards), negative reinforcement (removal of money losses), and combined reinforcement (money rewards and removal of money losses) groups. In addition, in order to evaluate the engagement of emotional activity in the different reinforcement processes, Positive and Negative Affect Schedule-Expanded Form (PANAS-X) scales were applied before and after the experiment to detect the emotional changes. The results showed that there was no difference between groups in the dopamine-related learning bias. However, compared to the other three groups, negative reinforcement elicited smaller FRN (the difference-wave measure) during the learning, stronger positive affect and joviality, and less fatigue after the learning, in which the difference between the negative and positive reinforcement groups was smaller. The results indicated that pure avoidance motivation may induce distinct emotional fluctuations, which influence the feedback processing. (shrink)

To study the different mechanisms of understanding figurative language in a speaker’s native language and their second language, this study investigated how scientific metaphors in Chinese and English are electrophysiologically processed via event-related potential experimentation. Compared with the metaphors from daily life or in literary works, scientific metaphors tend to involve both a more complicated context structure and a distinct knowledge-inferencing process. During the N400 time window, English scientific metaphors elicited more negative N400s than Chinese ones at the parietal region. (...) In the late positive component time window, English scientific metaphors elicited less positive LPCs than Chinese ones at the parietal region, and larger late negativities encompassing smaller areas of the brain. The findings might indicate that for late unbalanced bilingual speakers, L2 scientific metaphor comprehension requires more effort in information retrieval or access to the non-literal route. Altogether, the possible findings are that non-native and non-dominant language processing involves decreased automaticity of cognitive mechanisms, and decreased sensitivity to the levels of conventionality of metaphoric meanings.

While unethical behaviors that are intended to benefit the self are often severely punished, unethical behaviors that are intended to benefit the organization (unethical pro-organizational behaviors, UPBs) are disciplined within organizations at different levels of severity. Building on the sensemaking theoretical framework, we study how employees make sense of what the organization is like through observing what the organization has done (i.e., different levels of punishment imposed for UPBs) and how employees subsequently react to the results of sensemaking (i.e., affective (...) commitment to the organization)—increased or decreased turnover and UPB engagement intention. By conducting a vignette-based experimental study and a time-lagged field study, we find that affective commitment to the organization of observers, especially those with a high moral disengagement propensity, increases at a low-to-moderate level of punishment severity for UPBs, and decreases at a moderate-to-high level of punishment severity for UPBs. Furthermore, the impacted affective commitment to the organization subsequently leads to increase in observers’ UPB engagement (intention) and decrease in observers’ turnover intention. We also highlight implications for theory and practice. (shrink)

This study examines the role of responsible entrepreneurship among female entrepreneurs by examining how and when responsible entrepreneurship may exert a positive influence on female entrepreneurial success. Using the data collected from 337 Chinese female entrepreneurs, and by integrating responsible entrepreneurship research with a dynamic capability framework, our findings show, firstly, that responsible entrepreneurship is positively correlated to female entrepreneurial success; secondly, this relationship is mediated by female entrepreneurs’ opportunity recognition; and thirdly, the indirect effect of responsible entrepreneurship on female (...) entrepreneurial success through opportunity recognition is weaker when women entrepreneurs perceive more gender discrimination. Furthermore, using a post hoc analysis, we find that responsible entrepreneurship has a positive impact on entrepreneurial success for both male and female entrepreneurs, but that this impact is more significant for female entrepreneurs than for their male counterparts. With the contextual factor of traditional female social stereotypes inadvertently contributing to greater gender discrimination in the field of entrepreneurship, our results underscore the importance of both responsible entrepreneurship and opportunity recognition in promoting female entrepreneurial success.

Corruption as a non-market strategy for firms has gained increasing attention in the field of strategy management. However, the effect of corruption on innovation is unclear, especially in the context of transition economies. Using institutional theory, we examine the relationship between corruption and new product innovation and identify the contextual conditions of the relationship. Using the World Bank Enterprise Survey data from China, our empirical results show that corruption has a positive effect on firms’ new product innovation. Moreover, we find (...) that policy instability and competitive threats from the informal sector positively moderate the relationship between corruption and new product innovation. Using post hoc analysis, we find that the potentially positive effect of corruption on new product innovation is the consequence of inherent institutional weaknesses in transition economies; as the level of institutional development increases, the effect of corruption on firms’ new product innovation will gradually decrease. Overall, our findings provide new insights into understanding corrupt behaviors in transition economies and present managerial implications for firms’ ethical dilemmas in a transition economy context. We argue that the key to overcoming these ethical dilemmas lies in promoting pro-market institutional reform to reduce the potential benefits of corruption. (shrink)

Frequent human-media interaction via the electronic word-of-mouth platform, trust is acknowledged as an ongoing challenge. This study aimed to understand users' trust in the e-wom platform based on uses and gratifications theory and stimulus-organism-response paradigm. Utilitarian gratification was regarded as stimulus, social gratification and positive emotion as organism, and platform trust as response. Data was acquired from 268 users in China using a questionnaire survey, and the PLS-SEM was used to further analyze the results. The results indicated that there is (...) a hierarchy relationship between types of gratifications. That is, utilitarian gratification is a premise of social gratification. Moreover, sense of self-esteem and positive emotion have a mediating effect between perceived information quality and platform trust. Sense of social belonging and positive emotion have a mediating effect between perceived privacy protection and platform trust. This study not only broadened trust between human and media, but also purposed a hierarchy relationship of different types of gratifications in e-wom platform. (shrink)

Micro-expressions, as fleeting facial expressions, are very important for judging people’s true emotions, thus can provide an essential behavioral clue for lie and dangerous demeanor detection. From embodied accounts of cognition, we derived a novel hypothesis that facial feedback from upper and lower facial regions has differential effects on micro-expression recognition. This hypothesis was tested and supported across three studies. Specifically, the results of Study 1 showed that people became better judges of intense micro-expressions with a duration of 450 ms (...) when the facial feedback from upper face was enhanced via a restricting gel. Additional results of Study 2 showed that the recognition accuracy of subtle micro-expressions was significantly impaired under all duration conditions (50 ms, 150 ms, 333 ms, and 450 ms) when facial feedback from lower face was enhanced. In addition, the results of Study 3 also revealed that blocking the facial feedback of lower face, significantly boosted the recognition accuracy of subtle and intense micro-expressions under all duration conditions (150 ms and 450 ms). Together, these results highlight the role of facial feedback in judging the subtle movements of micro-expressions. (shrink)

In transitional economies, the governing central authorities impose heavy regulatory burdens on firms, which results in great costs for business in terms of time, resources, and other constraints. However, quality assurance through decentralized institutions (such as private certified management standards) is rapidly becoming more prevalent. This study examines the contingent implications that such decentralized institutions have for centralized regulation by focusing on the relationship between international certifications and regulatory burdens. As two prominent features of the institutional environment in emerging economies, (...) the threat of competition from the informal sector and corruption may influence the relationship between international certifications and regulatory burdens. These features are therefore examined in terms of their moderating roles. The study draws on institutional and signaling theories to interpret data from a survey conducted by the World Bank in China in 2012. The empirical results show that international certification is negatively associated with regulatory burdens. This relationship is strengthened by the threat of competition from the informal sector, but mitigated by a corrupt business environment. Our study contributes to the institutional literature and to research on international certifications, and it has implications for both business management and governmental policy. (shrink)

This study focuses on user experience from the perspective of big data to complete the aggregation, clustering, and visual presentation of knowledge. Using a combination of sample literature review, visualization technologies, knowledge map analysis, Carrot2 clustering, and other methodologies, this study intends to examine user experience from three perspectives: research state, hotspots, and trends. First, based on the double-map overlay, core institutions, core countries, core authors, core journals, and core references distribution research, the knowledge flow, research power, and research subjects (...) of user experience are analyzed. Secondly, through keyword clustering analysis, this research intuitively presents the research topics of user experience and reveals the research hotspots and the evolution path of research methods. Finally, with the help of the subject clustering algorithm, the emerging trends of user experience research are predicted: the immersive experience upgrade of multi-scenario integration, the innovative design of multi-role collaboration, and the cross-disciplinary interactive exploration of multi-discipline. Following this, the user experience knowledge map is constructed, providing a global view and macro-cognition for subsequent research. (shrink)

本书对处于社会转型期中国的审美文化特性以及其中出现的种种让人困惑的问题,从不同角度、不同层面作了阐述。.

While rules and exemplars are usually viewed as opposites, this paper argues that they form end points of the same distribution. By representing both rules and exemplars as (partial) trees, we can take into account the fluid middle ground between the two extremes. This insight is the starting point for a new theory of language learning that is based on the following idea: If a language learner does not know which phrase‐structure trees should be assigned to initial sentences, s/he allows (...) (implicitly) for all possible trees and lets linguistic experience decide which is the “best” tree for each sentence. The best tree is obtained by maximizing “structural analogy” between a sentence and previous sentences, which is formalized by the most probable shortest combination of subtrees from all trees of previous sentences. Corpus‐based experiments with this model on the Penn Treebank and the Childes database indicate that it can learn both exemplar‐based and rule‐based aspects of language, ranging from phrasal verbs to auxiliary fronting. By having learned the syntactic structures of sentences, we have also learned the grammar implicit in these structures, which can in turn be used to produce new sentences. We show that our model mimicks children’s language development from item‐based constructions to abstract constructions, and that the model can simulate some of the errors made by children in producing complex questions.

The potential anesthetic neurotoxicity on the neonate is an important focus of research investigation in the field of pediatric anesthesiology. It is essential to understand how these anesthetics may affect the development and growth of neonatal immature and vulnerable brains. Functional magnetic resonance imaging has suggested that using anesthetics result in reduced functional connectivity may consider as core sequence for the neurotoxicity and neurodegenerative changes in the developed brain. Anesthetics either directly impact the primary structures and functions of the brain (...) or indirectly alter the hemodynamic parameters that contribute to cerebral blood flow in neonatal patients. We hypothesis that anesthetic agents may either decrease the brain functional connectivity in neonatal patients or animals, which was observed by fMRI. This review will summarize the effect and mechanism of anesthesia on the rapid growth and development infant and neonate brain with fMRI through functional connectivity. It is possible to provide the new mechanism of neuronal injury induced by anesthetics and objective imaging evidence in animal developing brain. (shrink)

How is scientific knowledge used, adapted, and extended in deriving phenomena and real-world systems? This paper aims at developing a general account of 'applying science' within the exemplar-based framework of Data-Oriented Processing (DOP), which is also known as Exemplar-Based Explanation (EBE). According to the exemplar-based paradigm, phenomena are explained not by deriving them all the way down from theoretical laws and boundary conditions but by modelling them on previously derived phenomena that function as exemplars. To accomplish this, DOP proposes to (...) maintain a corpus of derivation trees of previous phenomena together with a matching algorithm that combines subtrees from the corpus to derive new phenomena. By using a notion of derivational similarity, a new phenomenon can be modelled as closely as possible on previously explained phenomena. I will propose an instantiation of DOP which integrates theoretical and phenomenological modelling and which generalises over various disciplines, from fluid mechanics to language technology. I argue that DOP provides a solution for what I call Kuhn's problem and that it redresses Kitcher's account of explanation. (shrink)

Rousseau's conception of virtue is puzzling, for he sometimes defines virtue as self-mastery and sometimes as patriotism. The prevailing Kantian interpretation emphasizes the first definition with its man-citizen thesis, while attributing the latter to Rousseau's inconsistency. This article challenges this reading and argues that Rousseau intentionally operates with two conceptions of virtue: political virtue as love of fatherland and moral virtue as love of humanity. While the former relies on a state-level amour-propre that draws motivation from the division between nations, (...) the latter hinges on conscience—an intelligent form of amour de soi—that reaches universal humanity. Underlying the two virtues is the irreconcilable tension between nature and politics. Where nature demands universal happiness incorporating all humans, politics necessitates passions that entail division. Retrieving Rousseau's dual conception of virtue highlights Rousseau's fundamental pessimism toward human politics, which has been blurred in the emerging Kantian-liberal scholarship. (shrink)

BackgroundEthically challenging critical events and decisions are common in nursing homes. This paper presents nursing home doctors’ descriptions of how they include the patient and next of kin in end-of-life decisions.MethodsWe performed ten focus groups with 30 nursing home doctors. Advance care planning; aspects of decisions on life-prolonging treatment, and conflict with next of kin were subject to in-depth analysis and condensation.ResultsThe doctors described large variations in attitudes and practices in all aspects of end-of-life decisions. In conflict situations, many doctors (...) were more concerned about the opinion of next of kin than ensuring the patient’s best interest.ConclusionsMany end-of-life decisions appear arbitrary or influenced by factors independent of the individual patient’s values and interests and are not based on systematic ethical reflections. To protect patient autonomy in nursing homes, stronger emphasis on legal and ethical knowledge among nursing home doctors is needed. (shrink)

According to Marx’s unfinished critique of political economy, capitalist relations of production rely on what Marx refers to in Capital as ‘the mute compulsion of economic relations’. The aim of this article is to demonstrate that this constitutes a distinct form of economic power which cannot be reduced to either ideology or violence, and to provide the conceptual groundwork for a systematic theory of capital’s mute compulsion.
