A major challenge for semantic video segmentation is how to exploit the spatiotemporal information and produce consistent results for a video sequence. Many previous works utilize the precomputed optical flow to warp the feature maps across adjacent frames. However, the imprecise optical flow and the warping operation without any learnable parameters may not achieve accurate feature warping and only bring a slight improvement. In this paper, we propose a novel framework named Dynamic Warping Network to adaptively warp the interframe features (...) for improving the accuracy of warping-based models. Firstly, we design a flow refinement module to optimize the precomputed optical flow. Then, we propose a flow-guided convolution to achieve the adaptive feature warping based on the refined optical flow. Furthermore, we introduce the temporal consistency loss including the feature consistency loss and prediction consistency loss to explicitly supervise the warped features instead of simple feature propagation and fusion, which guarantees the temporal consistency of video segmentation. Note that our DWNet adopts extra constraints to improve the temporal consistency in the training phase, while no additional calculation and postprocessing are required during inference. Extensive experiments show that our DWNet can achieve consistent improvement over various strong baselines and achieves state-of-the-art accuracy on the Cityscapes and CamVid benchmark datasets.

The general consensus emerging from decades of empirical investigation of metaphor processing is that, when appropriately contextualised, metaphorically used language is no more demanding of processing effort than literally used language. However, there is a small number of studies which contradict this position, notably Noveck, Bianco, and Castry (2001): they maintain that relevance-based pragmatic theory predicts increased cognitive costs incurred in deriving the extra effects that metaphors typically yield, and they provide experimental results that support this prediction. In our study, (...) we first surveyed and assessed the tasks and stimulus materials of many experiments on metaphor processing from the 1970's to the present day. The most telling result was an apparent disparity between the processing of metaphorical language used predicatively versus referentially. We then ran two self-paced reading experiments to test our hypothesis that when used as a predicate, metaphorical language is no more costly than literal language, but when used referentially, it does incur extra costs, even given a preceding biasing context. In the first experiment, all metaphorical referring expressions were in subject position so occurred early in the sentence; in the second experiment, we controlled for any effect of sentence position by placing metaphorical referring expressions in object position, thus later in the sentence, similar to the predicate metaphors. In both cases, metaphorical referring incurred significantly greater costs relative to literal equivalents than did metaphorical predication, with no effect of sentence position. We end with a brief analysis of why the referential use of metaphor is special and effort-demanding. (shrink)

This study explores how and when ethical leadership predicts three forms of team-level creativity, namely team creativity, average of member creativity, and dispersion of member creativity. The results, based on 230 members of 44 knowledge work teams from Chinese organizations, showed that ethical leadership was positively related to team creativity and average of member creativity but was negatively related to dispersion of member creativity. Consistent with the predictions of uncertainty reduction theory, psychological safety climate mediated the relationship between ethical leadership (...) and the three forms of team-level creativity. Furthermore, supervisor support for creativity positively moderated the effect of ethical leadership on psychological safety climate and the indirect effects of ethical leadership on the three forms of team-level creativity through psychological safety climate. The analysis offers significant theoretical and practical implications on ethical leadership and creativity in organizations. (shrink)

This exploratory research compares the interactive metadiscourse use by native English-speaking English for academic purposes writing teachers in the United Kingdom and their non-native counterparts in the Chinese contexts. The analysis is based on a self-compiled corpus, including two sub-corpora, which were composed of instructor contributions to classroom discourse: eight sessions of EAP lessons from the Chinese context and eight sessions of EAP lessons from the British context. Adopting an interpersonal model of metadiscourse, the two sub-corpora were compared to examine (...) the similarities and differences in their use of interactive metadiscourse. Findings of the comparative analysis reveal that EAP teachers from both contexts rely heavily on transition markers and frame markers to organize their teaching but differ in particular linguistic realizations. This may indicate the impact of a range of factors such as logical preferences, development order of acquisition, discourse community, and speech community on teachers’ interactive metadiscourse strategies. The article concludes with a few implications for metadiscourse research in spoken academic genres. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 63.1 (2002) 1-17 [Access article in PDF] What if the Father Commits a Crime? Rui Zhu Apparently, Socrates and Confucius respond similarly to the question if a son should turn in his father in the case of the father's misdemeanor. When Euthyphro, flaring his pride of his moral impartiality, tells Socrates that he is on his way to report his father because he (...) has thrown one of the household slaves into a ditch and left him bound there until he was dead, Socrates says, "Good Heaven! Certainly, Euthyphro, most men would not know how they could do this and be right. It is not the part of anyone to do this, but of one who is far advanced in wisdom." 1According to Socrates, only a man of high wisdom knows how to prosecute his father righteously, but Euthyphro does not appear to have this wisdom. When his interlocutor observes that an upright man in his state would bear witness against his father if he misappropriates a sheep, Confucius contradicts the interlocutor's understanding of uprightness by speaking in a matter-of-fact tone: "In my country the upright men are of quite another sort. A father will cover up for his son, and a son his father—which incidentally does involve a sort of up—rightness." 2Confucius stands on the same line with Socrates but seems the more radical of the two. Socrates does not directly refute Euthyphro and only suggests that he make sure he understands what he is doing before going any further. Socrates is not only typically Socratic—indirect and suggestive—but also sounds so reasonable that Euthyphro appears in contrast to be a reckless youth who harbors [End Page 1] only a faint understanding of morality. Confucius's response is more rigid, for he categorically dismisses an act of the Euthyphroian kind. He demands that father and son cover up for each other in the case of either one's guilt. Compared to Socrates, Confucius advocates the position that seems a little too strong and leaves no room for justice, while Socrates does not have that problem with justice. This is how we feel about Socrates and Confucius on our first impression. The prima facie observations that we make from the remarks of Socrates and Confucius seem both plain and unproblematic.By embedding these remarks into their respective social or philosophical cultures, this paper will show that our previous observations are not quite accurate. The apparent affinity of the Socratic and Confucian stances belies different underlying moral philosophies. We want to use their comments as bridges to explore the early Greek and Confucian ethics and show how different a picture we see after things are examined within their traditions.The issue of a possible father-son conflict may be treated as a case study of the early Greek (the Heroic era until the age of Socrates) and early Confucian (Confucius and Mencius) morals. There is a strong theme in the early Greek morals that allows, or sometimes demands, a son such as Euthyphro to prosecute his father for the sake of justice, because justice, instead of love (philein) or filial piety, is the governing principle in the early Greek ethics. Confucian ethics is founded on love (human-heartedness), which in turn is extended from the love between father and son. All moral principles including justice are derived from this extension of love. The mutual love of father and son then becomes the governing principle in the case of Confucianism. A Guilty Father: The Greek Motif The question, "What if the father commits a crime?" has a certain realistic aroma to a boy coming of age in the Hesiodic Greek world. That father has to be overcome by son before some relief from strife becomes possible is a familiar theme in Greek literature. In Hesiod's Theogony, Uranus (the sky) incurs hatred from all his newborn children since he hides them in their mother Gaia's womb and does not let them return to the light, for no reason...

Based on social cognitive theory, this paper explored the cognitive mechanism between ethical leadership and the followers’ extra-role performance. We tested a moderated mediation model in which general self-efficacy mediated the relationship between ethical leadership and the employee extra-role performance, while intrinsic motivation moderated the relationship between ethical leadership and subordinate’s general self-efficacy. Data were collected in two waves from 208 dyads. Results supported the time-lagged effect of ethical leadership on individual extra-role performance and the mediating role of general self-efficacy. (...) Moreover, our findings revealed that intrinsic motivation positively moderated the effect of ethical leadership on general self-efficacy. Furthermore, intrinsic motivation also moderated the indirect effect of ethical leadership on extra-role performance via general self-efficacy. Theoretical and practical implications were further discussed. (shrink)

Adaptation can optimize information processing by allowing the visual system to always adjust to the environment. However, only a few studies have investigated how the visual system makes adjustments to repeatedly occurring changes in the input, still less about the related neural mechanism. Our previous study found that contrast adaptation attenuated after multiple daily sessions of repeated adaptation, which was explained by the habituation of either the adapter’s effective strength or the adaptation mechanisms. To examine the former hypothesis, in the (...) present study we used the frequency tagging technique to measure the adapter-elicited steady-state visual evoked potential amplitudes. Participants repeatedly adapted to the same contrast adapter in a top-up manner for six continuous days, which was called training of adaptation. The behavioral adaptation effect and SSVEP response to the trained adapter and an untrained control adapter were measured before and after training. The psychophysical results showed that the effect of adaptation in the trained condition significantly reduced after training, replicating our previous finding. Contradicting the prediction of the hypothesis that repeated adaptation attenuated the effective strength of the adapter, the SSVEP amplitude was unchanged after training, which was further confirmed by an equivalence test. Taken together, the results challenge the account of habituation of adapter in repeated adaptation, while leaving the account of habituation of adaptation mechanism to be tested. (shrink)

As one of the three systems of China's traditional culture, Daoism has an important place in the history of Chinese philosophy. Based on the ideas of inaction performing all, the Way modeling spontaneity, and the dialectic of you [having, being] and wu [lacking, nonbeing], this article is a systematic exploration of Laozi's philosophy of denial, spontaneity, and atheism, as well as of the deep and lasting influence of his metaphysical principles on all schools of traditional Chinese philosophy.

In nontheistic moral traditions, there is a typical ethical conundrum concerning the relation between cosmic order and human agency. Within those traditions, it is generally recognized that the universe has its own order and history that are independent of human will. A moral discourse has to find space to accommodate human agency in the midst of the iron grid of cosmic law. Both Confucius and Aurelius use the concept of timeliness (kairos) to resolve the difficult issue. But their philosophies take (...) on divergent paths. By studying their resolutions of the issue, we will be able to appreciate the distinctive nature of their nontheistic moral narratives. (shrink)

It has been contended that ostracism is prevalent in the workplace, and there has been increasing research interest in its potential effects. This paper extends the theoretical framework of workplace ostracism by linking it with affective commitment and intention to leave from the perspective of job embeddedness. Using time-lagged data from China, we apply job embeddedness theory to confirm that workplace ostracism decreases the cultivation of job embeddedness, which in turn undermines affective commitment and induces intention to leave. We also (...) find that intrinsic work motivation strengthens the detrimental effects of workplace ostracism on job embeddedness such that the negative relationship is stronger when intrinsic motivation is high rather than low. We further discuss the theoretical and practical implications of our findings and offer future research directions. (shrink)

Enterprises often post branded content on social media and adopt a proactive response approach to improve digital customer engagement to gain a competitive advantage. However, there are many brands which fail to operate social media as effectively as expected. The effective use of brand social media strategies to improve digital customer engagement remains an ongoing challenge for the enterprises. Based on firm-generated content theory and social presence theory, this study aims to identify the impact of brand social media strategies on (...) different levels of digital customer engagement, including positive filtering, cognitive and affective processing as well as advocacy from content strategy and response strategy. Based on 1,519 brand posts on the official Weibo pages of eight of the top 500 Chinese brands in 2021, this study uses a multiple linear regression model to examine the impact of brand social media strategies on digital customer engagement and the moderating effects of brand image and discretionary purchases. The findings show that, on the one hand, among the brand social media content strategies, action content strategy is associated with higher levels of digital customer engagement. On the other hand, different brand social media response strategies have a differential impact on digital customer engagement levels, with cohesive response being the best strategy for increasing digital customer engagement level. In addition, the effectiveness of brand social media response strategy in digital customer engagement is further moderated by the brand image and discretionary purchases. In contrast, the effectiveness of brand social media response strategy in digital customer engagement is stronger when the brand image emphasizes its “competence” or the discretionary purchases focus on “material purchases.” This study not only enriches the research on digital customer engagement but also provides a reference for the brand strategy selection, design and management based on social media.

Human aesthetic practices show a sensitivity to the ways that the appearance of an artefact manifests skills and other qualities of the maker. We investigate a possible origin for this kind of sensibility, locating it in the need for co-ordination of skill-transmission in the Acheulean stone tool culture. We argue that our narrative supports the idea that Acheulian agents were aesthetic agents. In line with this we offer what may seem an absurd comparison: between the Acheulian and the Quattrocento. In (...) making it we display some hidden richness in what counts as an aesthetic response to an artefact. We conclude with a brief review of rival explanations—biological and/or cultural—of how this skills-based sensibility became a regular feature of human aesthetic practices. (shrink)

When participants observed a rubber hand being touched, their sense of touch was activated . While this illusion might be caused by multi-modal integration, it may also be related to empathic function, which enables us to simulate the observed information. We examined individual differences in the RHI, including empathic and schizotypal personality traits, as previous research had suggested that schizophrenic patients would be more subject to the RHI. The results indicated that people who experience a stronger RHI might have stronger (...) empathic and schizotypal personalites simultaneously. We discussed these relationships in terms of self-other representations. (shrink)

Engineering programs in the United States have been experimenting with diverse pedagogical approaches to educate future professional engineers. However, a crucial dimension of ethics education that focuses on the values, personal commitments, and meaning of engineers has been missing in many of these pedagogical approaches. We argue that a value-based approach to professional ethics education is critically needed in engineering education, because such an approach is indispensable for cultivating self-reflective and socially engaged engineers. This paper starts by briefly comparing two (...) prevalent approaches to ethics education in science and engineering: professional and philosophical. While we acknowledge that both approaches help meet certain ethics education objectives, we also argue that neither of these is sufficient to personally engage students in authentic moral learning. We make the case that it is important to connect ethics education to the heart, which is extensively driven by values, and present a value-based approach to professional ethics education. We provide some classroom practices that cultivate a safe, diverse, and engaging learning environment. Finally, we discuss the implications of a value-based approach to professional ethics education for curriculum design and pedagogical practice, including opportunities and challenges for engineering faculty eager to incorporate value-based inquiry into their classrooms.

The fault prediction and abductive fault diagnosis of three-phase induction motors are of great importance for improving their working safety, reliability, and economy; however, it is difficult to succeed in solving these issues. This paper proposes a fault analysis method of motors based on modified fuzzy reasoning spiking neural P systems with real numbers for fault prediction and abductive fault diagnosis. To achieve this goal, fault fuzzy production rules of three-phase induction motors are first proposed. Then, the rMFRSNPS is presented (...) to model the rules, which provides an intuitive way for modelling the motors. Moreover, to realize the parallel data computing and information reasoning in the fault prediction and diagnosis process, three reasoning algorithms for the rMFRSNPS are proposed: the pulse value reasoning algorithm, the forward fault prediction reasoning algorithm, and the backward abductive fault diagnosis reasoning algorithm. Finally, some case studies are given, in order to verify the feasibility and effectiveness of the proposed method. (shrink)

With the development of industrialization and urbanization, cities have become the main carriers of economic activities. However, the long-term development of cities has also caused damage to resources and the environment. Hence, objective and scientific evaluation of urban low-carbon sustainable development capacity is very important. An index system of urban low-carbon sustainable development capability is constructed in this paper, and a TOPSIS-BP neural network model is established to evaluate the low-carbon sustainable development capability of Beijing, Shanghai, Shenzhen, and Guangzhou in (...) China. At the same time, the difference degree of low-carbon sustainable development level in these four cities is analyzed by standard deviation and coefficient of variation, and the influencing factors of urban low-carbon sustainable development ability are extracted by grey correlation analysis. The results show that the capability of low-carbon sustainable development in four cities is rising and the difference of low-carbon sustainable development capability is decreasing; the general view that the higher the general investment in low-carbon sustainable development, the higher the level of low-carbon sustainable development in cities has not been verified; with the change of time series, the factors affecting the capability of low-carbon sustainable development in the same city are different and the influence of the same factor on the capability of low-carbon sustainable development in different cities is different.
