The innovation activities of new generation of employees have the characteristics of double network embeddedness, and the degree of psychological contract fulfilment is an important factor that affects their innovation performance. Based on the attributes of internal network embeddedness and external network embeddedness, this paper builds a hypothesis model of the relationship between network embeddedness, psychological contract and innovation performance. It explores the impact and mechanism of network embeddedness on the innovation performance of new generation of employees and the mediating (...) role of the psychological contract. Empirical research shows that network embeddedness has a positive effect on the innovation performance of new generation of employees. The psychological contract has a mediating role in network embeddedness on innovation performance of new generation of employees. These conclusions continue and deepen the research on network embeddedness and innovation performance and further enrich and expand the application of social networks in the research of individual innovation performance of new generation of employees.

Research investigating the underlying mechanisms and boundary conditions under which leader humility influences employee voice remains underdeveloped. Drawing from approach–inhibition theory of power and leader humility literature, we developed a moderated-mediation model in which personal sense of power (i.e., employees’ ability to influence other individuals such as their leader) was theorized as a unique mechanism underlining why employees feel motivated to speak up under the supervision of humble leaders. Additionally, the cultural value of power distance was proposed to be a (...) relevant boundary condition to influence such relationship. We tested the model using time-lagged supervisor–subordinate matched data. Results of mixed models analyses provided support for our hypotheses confirming that employees’ personal sense of power mediates the relationship between leader humility and employee voice, and such relationship was found to be stronger when employees’ power distance was lower rather than higher.

This paper presents a bioinspired lower extremity exoskeleton robot. The proposed exoskeleton robot can be adjusted in structure to meet the wearer’s height of 150–185 cm and has a good gait stability. In the gait control part, a method of identifying different locomotion modes is proposed; five common locomotion modes are considered in this paper, including sitting down, standing up, level-ground walking, ascending stairs, and descending stairs. The identification is depended on angle information of the hip, knee, and ankle joints. (...) A deep locomotion mode identification model based on long-short term memory architecture is proposed in this paper for exploiting the angle data. We conducted two experiments to verify the effectiveness of the proposed method. Experimental results show that the DLMIM is capable of learning inherent characteristics of joint angles and achieves more accurate identification than the other models. The last experiment demonstrates that the DLMIM can recognize transitions between different locomotion modes in time and the real-time performance varies with each individual. (shrink)

ABSTRACT This corpus-assisted critical discourse study examines news reports published by China’s official English-language media from 2000 to 2018, with the goal of understanding how they represent LGBTQ+ issues within the China’s socio-political context. Analysis reveals that the discussion of LGBTQ+-related topics has been consistently discouraged in China’s official English-language media, and the few news reports which have appeared in these media sources have focused on preventing the spread of HIV/aids through homosexual behaviors, on promoting LGBTQ+ rights, and on advocating (...) for the liberalization of sex education in China. The range of these focuses indicates that, despite widely-held negative stereotypes regarding homosexual behaviors and their relation to the spread of HIV/aids, the official English-language media of China have endeavored to project a positive image of the Chinese central government’s efforts to construct a society that is open, inclusive, and tolerant of LGBTQ+ individuals. This study also discusses positive changes in the social well-being of LGBTQ+ persons in China as evidenced first by the more liberal attitudes that gradually have resulted from the efforts of Chinese netizens to influence LGBTQ+-related governmental policies and second, by the more positive representations of LGBTQ+ issues being communicated to global audiences through the China’s official English-language media.

This article investigates Charles Peirce’s development of logical calculi for classical propositional logic in 1880–1896. Peirce’s 1880 work on the algebra of logic resulted in a successful calculus for Boolean algebra. This calculus, denoted byPC, is here presented as a sequent calculus and not as a natural deduction system. It is shown that Peirce’s aim was to presentPCas a sequent calculus. The law of distributivity, which Peirce states in 1880, is proved using Peirce’s Rule, which is a residuation, inPC. The (...) transitional systems of the algebra of the copula that Peirce develops since 1880 paved the way to the 1896 graphical system of the alpha graphs. It is shown how the rules of the alpha system reinterpret Boolean algebras, answering Peirce’s statement that logical graphs supply a new system of fundamental assumptions to logical algebra. A proof-theoretic analysis is given for the connection betweenPCand the alpha system. (shrink)

Although the proliferation of empirical research has documented the association between parental control and school adjustment, findings of this linkage are still inconclusive. Moreover, fewer efforts have been made to address this association in middle school students. Guided by an ecological framework, the current study aimed to integrate the conflicting findings into a coherent body of knowledge, paying particular attention to two research purposes: (a) to examine the association between parental control and three objective indicators of school adjustment (social competence, (...) academic grades, and peer acceptance), and (b) to explore whether this association was moderated by individual characteristics of social identity and grit. A total of 120 Chinese middle school students (42.5% females) aged between 13 and 15 years old were recruited for this study, and research data was gathered from multiple sources. To be specific, students were asked to complete a set of self-report questionnaires concerning parental control, social identity, and grit. Meanwhile, school-related social competence was rated by head teachers; academic grades were obtained from school records; peer acceptance was assessed by sociometric nominations. The results from hierarchical regression analyses showed that parental control was negatively associated with academic grades. Moreover, when reporting higher levels of social identity, parental control was negatively related to social competence and peer acceptance for those students with lower levels of grit. Our findings suggest that parental control can dampen middle school students’ academic performance, and low levels of grit can magnify the detrimental effect of parental control on social competence and peer acceptance in middle school students who regard themselves as closely connected to social groups.

The tendency of customers’ preference to their local brands over the foreign ones is known as the consumer ethnocentrism, and it is one of the important issues in international marketing. This study aims at identifying the behavioral and neural correlates of Consumer Ethnocentrism in the field of brand preference by using Event-Related Potential (ERP). We sampled subjects from two ethnic groups, the Chinese ethnic group and the sub-Sahara black Africans group from the Zhejiang University. The subjects faced two sequential stimuli, (...) S1 followed by S2. The S1 consisted of 40 pictures of 20 Chinese and 20 Africans black peoples wearing traditional clothes, and S2 consisted of 40 fake brand-logos which were divided randomly into two groups of 20 each. The subjects were informed that the people in the S1 purchased and recommended the products with the brand-logos presented in S2, and the subjects were asked to rate their preference degree toward these logos. The brand-logos were called the “in-group recommended logos” if the recommender in S1 were the same race as the subjects, otherwise, the “out-group recommended logos”.The results revealed that the race of the brand-logo recommender highly impacted the Chinese subjects’ preference for the brand-logos. The N200 component elicited by in-group recommended logos were significantly lower than those elicited by out-group recommended logos. Besides, there was evidence that being familiar with foreign cultures reduces consumer ethnocentrism. The African subjects were familiar with Chinese people and adopted Chinese culture, as a result, they did not differ in showing preferences between in-group and out-group recommended logos. (shrink)

Although stressful life events have been shown to be a key risk factor for adolescent NSSI, the potential mediators and moderators of this relationship are unclear. Based on the social development theory and the organism-environment interaction model, we tested whether the link between stressful life events and adolescent NSSI was explained in part by deviant peer affiliation, and whether this process was buffered by gratitude. Chinese adolescents anonymously completed questionnaires to assess the study variables. The present study demonstrated that stressful (...) life events was linked to NSSI in part because of deviant peer affiliation, and high gratitude was a key protective factor to buffer this indirect effect. Teaching gratitude may be a helpful component of prevention and intervention programs to reduce adolescent NSSI. (shrink)

How did human vocalizations come to acquire meaning in the evolution of our species? Charles Darwin proposed that language and music originated from a common emotional signal system based on the imitation and modification of sounds in nature. This protolanguage is thought to have diverged into two separate systems, with speech prioritizing referential functionality and music prioritizing emotional functionality. However, there has never been an attempt to empirically evaluate the hypothesis that a single communication system can split into two functionally (...) distinct systems that are characterized by music- and languagelike properties. Here, we demonstrate that when referential and emotional functions are introduced into an artificial communication system, that system will diverge into vocalization forms with speech- and music-like properties, respectively. Participants heard novel vocalizations as part of a learning task. Half referred to physical entities and half functioned to communicate emotional states. Participants then reproduced each sound with the defined communicative intention in mind. Each recorded vocalization was used as the input for another participant in a serial reproduction paradigm, and this procedure was iterated to create 15 chains of five participants each. Referential vocalizations were rated as more speech-like, whereas emotional vocalizations were rated as more music-like, and this association was observed cross-culturally. In addition, a stable separation of the acoustic profiles of referential and emotional vocalizations emerged, with some attributes diverging immediately and others diverging gradually across iterations. The findings align with Darwin’s hypothesis and provide insight into the roles of biological and cultural evolution in the divergence of language and music. (shrink)

This article is devoted to the consideration of a number of stage projects by Chinese directors, in which the work of the writer Anton Pavlovich Chekhov is reinterpreted. Analysis of such productions and projects as the international drama festival "Chekhov Forever" in 2004, a hybrid work based on Chekhov's story "Three Sisters" and Beckett's novel "Waiting for Godot" by Lin Zhaohua in 1998 and 2018, a double performance by Stan Lai based on the works "I take You by the Hand" (...) by Carol Rocamora and "The Seagull" Chekhov 2014, etc. It allows us to trace innovative approaches to reading Chekhov's works in the context of the life of modern Chinese society. These works cause a great resonance not only in the professional environment, but also among the mass audience, who invariably penetrates the depth of Chekhov's images, the subtlest shades of emotional experiences; the Chinese audience finds themselves close to the problems, hopes and aspirations of the heroes, brilliantly transferred to the actual socio-cultural environment of China, always topical and recognizable. The scientific novelty of the article is connected with the fact that the nature of mastering the creativity of the Russian playwright in the theater of the East is a fairly new and at the same time promising topic for research. The conclusions and results of the study can become the basis for further studies of the specifics of the adaptation of foreign dramaturgy in the national theatrical tradition on the example of other countries and regions.

PurposeThe purpose of this paper is to examine how the shifting conceptualization of the democratizing potential of digital technology can be more comprehensively understood by bringing in science and technology studies perspectives to communication scholarship. The synthesis and discussion are aiming at providing an interdisciplinary theoretical framework for comprehensively understand the democratizing potential of digital technology, and urging researchers to be conscious of assumptions underpinning epistemological positions they take when examining the issue of democratizing potential of digital technology.Design/methodology/approachThe paper is (...) a constructive literature review that synthesizes and integrates existed literature from communication and STS on the democratizing potential of digital technology. The author attempts to bridge theoretical perspectives from communication and STS by identifying core arguments and debates around key concepts and discussing potential implications of different epistemological positions.FindingsTracing the evolving analytical perspectives of technological determinism, the social construction of technology and actor-network theory, the author argues that researchers should be aware of their underlying epistemological assumptions embedded in relationships among users, technological systems and social factors. Analyzing the contested notion of power in the democratizing potential of digital technology from two contrasting perspectives, the author argues that researchers should recognize both the front end and the back end of digital technology in their analysis. In addition, new challenges of algorithm opacity and accountability in impacting the democratizing potential of digital technology are further discussed.Originality/valueThis study provides an original interdisciplinary theoretical framework by reviewing and bridging scholarship from communication and STS in examining the democratizing potential of digital technology. Adopting this interdisciplinary theoretical framework helps researchers develop a more nuanced and comprehensive understanding of the democratizing potential of digital technology. (shrink)

Graded epistemic logic is a logic for reasoning about uncertainties. Graded epistemic logic is interpreted on graded models. These models are generalizations of Kripke models. We obtain completeness of some graded epistemic logics. We further develop dynamic extensions of graded epistemic logics, along the framework of dynamic epistemic logic. We give an extension with public announcements, i.e., public events, and an extension with graded event models, a generalization also including nonpublic events. We present complete axiomatizations for both logics.

Learning in natural environments is often characterized by a degree of inconsistency from an input. These inconsistencies occur, for example, when learning from more than one source, or when the presence of environmental noise distorts incoming information; as a result, the task faced by the learner becomes ambiguous. In this study, we investigate how learners handle such situations. We focus on the setting where a learner receives and processes a sequence of utterances to master associations between objects and their labels, (...) where the source is inconsistent by design: It uses both “correct” and “incorrect” object‐label pairings. We hypothesize that depending on the order of presentation, the result of the learning may be different. To this end, we consider two types of symbolic learning procedures: the Object‐Label (OL) and the Label‐Object (LO) process. In the OL process, the learner is first exposed to the object, and then the label. In the LO process, this order is reversed. We perform experiments with human subjects, and also construct a computational model that is based on a nonlinear stochastic reinforcement learning algorithm. It is observed experimentally that OL learners are generally better at processing inconsistent input compared to LO learners. We show that the patterns observed in the learning experiments can be reproduced in the simulations if the model includes (a) an ability to regularize the input (and also to do the opposite, i.e., undermatch) and (b) an ability to take account of implicit negative evidence (i.e., interactions among different objects/labels). The model suggests that while both types of learners utilize implicit negative evidence in a similar way, there is a difference in regularization patterns: OL learners regularize the input, whereas LO learners undermatch. As a result, OL learners are able to form a more consistent system of image‐utterance associations, despite the ambiguous learning task. (shrink)

Customer civility is an established construct in the study of ethical consumption. However, scholars have paid insufficient attention to customer civility in relation to the flourishing peer-to-peer economy. Therefore, the purpose of this article is to develop and test a theoretical framework which examines the antecedents of the customer civility in the P2P economy. We use social exchange theory to develop a model that posits customer interaction experiences with property owners, properties, and P2P platforms as antecedents of customer civility in (...) the P2P economy. Two studies were used to test our framework: Study 1 comprises a survey of Chinese customers ; Study 2 involves secondary data crawled from the Web site of Xiaozhu, one of China’s largest P2P accommodation platforms. OLS regression analysis was used for hypothesis testing. Results demonstrate three antecedents of customer civility in the P2P accommodation sector: interpersonal trust, property experience, and platform governance. In addition, the positive effect of interpersonal trust on customer civility is stronger when customers have high economic incentive, while the effect of property experience is significantly stronger when customers have low economic incentive.

ABSTRACTConsulting Heidegger's other texts composed during 1936–1942, this article employs a principle of charity and constructs a consistent discourse about an inceptual negativity Heidegger articulates through a confrontation with Hegel in GA 68. Heidegger deliberately differentiates his use of denial that bears Being-historical significance from Hegel's Negation that allegedly aims at synthesis or elevation as a dialectical movement. Being unsatisfied with his approach that remains entangled with metaphysics in the Contributions, Heidegger attempts to transform the question of the Nothing from (...) a subsidiary question to Beyng to an abyssal question. One needs to go under toward the Nothing in its concealed, conjoined, and most intimate relation to Beyng. The movement of going under is fundamentally significant for transitions that could occur from out of the history of Beyng. Never being the fullness of essence, the Nothing places a limit on Beyng, constantly thwarts its unfolding, and maint... (shrink)

Peirce introduced Existential Graphs in late 1896, and they were systematically investigated in his 1903 Lowell Lectures. Alpha graphs for classical propositional logic constitute the first part of EGs. The second and the third parts are the beta graphs for first-order logic and the gamma graphs for modal and higher-order logics, among others. As a logical syntax, EGs are two-dimensional graphs, or diagrams, in contrast to the linear algebraic notations. Peirce's theory of EGs is not only a theory of logical (...) syntax but also a proof theory for many logics. A set of transformation rules of graphs defines a proof system for a graphical logic.

The earliest extant mathematical books from China contain a lot of problems and data about grains. They also betray a close relationship with imperial bureaucracy in this respect. Indeed, these texts quote administrative regulations about grains. For instance, the Book on mathematical procedures 筭數書, found in a tomb sealed ca. 186 BCE, has a section in common with the “regulations on granaries” from the Qin statutes in eighteen domains, known thanks to slips excavated at Shuihudi. Mathematical writings also deal with (...) official vessels used to measure grains. They cast light on statements from, and practices evidenced by, official histories and administrative documents. This article addresses the following issues. Which information about the concrete management of grains can we derive from mathematical writings in relation to administrative documents? Which data can we find in these writings about continuities and changes in the management of grains in the time span between the Qin and Han dynasties? In particular, how can we account for the fact that in a later mathematical text, namely, The Nine Chapters, probably completed in the first century CE, there was a change in the form in which the data about grain equivalences were given, by comparison with the “regulations on granaries”? Finally, what do our conclusions imply with respect to the nature of the earliest extant mathematical writings. In this article, we gather the various types of statement that mathematical writings contain about grains and offer several elements of interpretation for the “regulations on granaries” and the related text in The Nine Chapters. From this perspective, we offer several hypotheses about the management of grain in the Qin and Han dynasties. (shrink)

Chan has been one of the most prominent sects of Chinese Buddhism since the mid and late Tang Dynasty and it has been particularly well-known around the world. The Platform Sutra purports to convey the teachings of Huineng, one of the most revered figures in the Chan tradition, and the text has been regarded as the most reliable source for the study of Chan. This canonical Buddhist text is generally categorized into four different versions: 1) Dunhuang ; 2) Huixin ; (...) 3) Qisong ; and, 4) Zongbao.

To solve the problem that traditional trajectory prediction methods cannot meet the requirements of high-precision, multi-dimensional and real-time prediction, a 4D trajectory prediction model based on the backpropagation (BP) neural network was studied. First, the hierarchical clustering algorithm and the k-means clustering algorithm were adopted to analyze the total flight time. Then, cubic spline interpolation was used to interpolate the flight position to extract the main trajectory feature. The 4D trajectory prediction model was based on the BP neural network. It (...) was trained by Automatic Dependent Surveillance – Broadcast trajectory from Qingdao to Beijing and used to predict the flight trajectory at future moments. In this paper, the model is evaluated by the common measurement index such as maximum absolute error, mean absolute error and root mean square error. It also gives an analysis and comparison of the predicted over-point time, the predicted over-point altitude, the actual over-point time and the actual over-point altitude. The results indicate that the predicted 4D trajectory is close to the real flight data, and the time error at the crossing point is no more than 1 min and the altitude error at the crossing point is no more than 50 m, which is of high accuracy.

We develop a paraconsistent logic by introducing new models for conditionals with acceptive and rejective selection functions which are variants of Chellas’ conditional models. The acceptance and rejection conditions are substituted for truth conditions of conditionals. The paraconsistent conditional logic is axiomatized by a sequent system \ which is an extension of the Belnap-Dunn four-valued logic with a conditional operator. Some acceptive extensions of \ are shown to be sound and complete. We also show the finite acceptive model property and (...) decidability of these logics. (shrink)

Our understanding of the complexity of the oral biome and of the role of the various constituent bacteria in the aetiology of dental disease is growing. Probiotics and their relationship with prebiotics, as well as other microbiome‐based interventions, could be useful in preventing and treating dental disease and in promoting oral health. However, given the promise and early stage of this treatment approach, there are also a number of ethical, social and regulatory issues associated with innovative probiotic therapy. In this (...) article, a brief update is given on contemporary theories of the aetiology and management of the two commonest dental diseases, and on the roles of pre‐ and probiotics and oral biome transplant in the management of these diseases. The focus is primarily on four core issues: informed consent, risk–benefit assessment, how to determine suitable healthy donors, and commercialization and regulation. We discuss the safety and benefits of oral probiotics, not only concerning the products and quality control during their manufacture, but also regarding the depth of public knowledge about this topic. We point out that the requirement of listing ingredients honestly might be insufficient, and that the prevalent rhetoric of ‘natural’ and ‘organic’ as well as some health claims in the translational, innovative probiotic industry and markets are themselves misleading and should be carefully scrutinized. Finally, we suggest an ethical imperative to find a balance between scientific research and industry, and public health in the regulation of probiotics. (shrink)

The main aim of this essay is to show that, for Stevens, the concept of reality is very fluctuating. The essay begins with addressing the relationship between poetry and philosophy. I argue, contra Critchley, that Stevens’ poetic work can elucidate, or at least help us to understand better, the ideas of philosophers that are usually considered obscure. The main “obscure” philosophical work introduced in and discussed throughout the essay is Schelling’s System of Transcendental Idealism. Both a (shellingian) philosopher and a (...) (stevensian) poet search for reality. In order to understand Stevens’ poetry better, I distingush several concepts of reality: initial reality (the external world of the common sense), imagined reality (a fiction, a product of one’s mind), final reality (the object of a philosopher’s and a poet’s search) and total reality (the sum of all realities, Being). These determinations are fixed by reason (in the present essay), whereas in Stevens’ poetic works, they are made fluid by the imagination. This fluidity leads the concept of reality from its initial stage through the imagined stage to its final stage. Throughout this process, imagined reality must be distinguished from both a mere fancy and its products. Final reality is, however, nothing transcendent. It is rather a general transpersonal order of reality created by poetry/the imagination. The main peculiarity of final reality is that it is a dynamic order. It is provisional at each moment. Stevens (and Schelling too) characterizes this order as that of a work of art which is a finite object, but has an infinite meaning. Stevens calls this order “the central poem” or the “endlessly elaborating poem”. If ultimate reality is a poem created by the imagination, one may ask who is the imagining subject. I argue that this agent is best to be thought as total reality, that is, as Being. Stevens, however, maintains that if there were such an agency, it would be an inhuman agency, “an inhuman meditation”. The essay concludes, in a Derridian manner, with the claim that this agency cannot have any name; it is the “unnamed creator of an unknown sphere, / Unknown as yet, unknowable, / Uncertain certainty” (OP: 127). It is best thought as an X, as an unknown variable. Being has no name. (shrink)
