In a sample of 522 police officers and staff in an English police force, we investigated the role of authoritarian leadership in reducing the levels of employee ethical voice. Drawing upon uncertainty management theory, we found that authoritarian leadership was negatively related to employee ethical voice through increased levels of felt uncertainty, when the effects of a motivational-based mechanism suggested by previous studies were controlled. In addition, we found that the negative relationship between authoritarian leadership and employee ethical voice via (...) felt uncertainty is mitigated by higher levels of benevolent leadership. That is, when authoritarian leaders simultaneously exhibit benevolence, they are less likely to cause feelings of uncertainty in their followers who are then more likely to speak up about unethical issues. We discuss theoretical and practical implications of the findings. (shrink)

As one of the basic elements in acoustic events, timbre influences the brain collectively with other factors such as pitch and loudness. Research on timbre perception involve interdisciplinary fields, including physical acoustics, auditory psychology, neurocognitive science and music theory, etc. From the perspectives of psychology and physiology, this article summarizes the features and functions of timbre perception as well as their correlation, among which the multi-dimensional scaling modeling methods to define timbre are the focus; the neurocognition and perception of timbre (...) are outlined; related experiment findings on the deeper level of timbre perception in terms of neural cognition are summarized. In the meantime, potential problems in the process of experiments on timbre perception and future possibilities are also discussed. Thought sorting out the existing research contents, methods and findings of timbre perception, this article aims to provide heuristic guidance for researchers in related fields of timbre perception psychology, physiology and neural mechanism. It is believed that the study of timbre perception will be essential in various fields in the future, including neuroaesthetics, psychological intervention, artistic creation, rehabilitation, etc. (shrink)

During the past four decades, China has gone through rapid urbanization and modernization. As people adapt to dramatic sociodemographic shifts from rural communities to urban centers and as economic level rises, individualistic cultural values in China have increased. Meanwhile, parent and child behavior in early childhood has also evolved accordingly to match a more individualistic society. This mixed-method study investigated how social change in China may have impacted parenting goals and child development in middle childhood, as seen through the eyes (...) of the current generation of mothers. Thirty mothers of fifth-grade elementary school students from Shenzhen, China were recruited and took part in semi-structured interviews. Participants answered questions and provided examples about their children’s life, their own childhood, and the perceived differences between the two generations. Participating mothers were also asked to rate which generation, themselves or their parents, cared more about the childrearing goals of academic competitiveness and socioemotional well-being. Using both qualitative and quantitative analysis, we expected and found an intergenerational increase in the perceived value mothers placed on individualistic traits: current mothers care more about their children’s academic competitiveness, personal happiness, and social adjustment, compared to their experience of their own mothers’ attitudes during their childhood a generation earlier. They also experience conflict between their children’s academic competitiveness and socioemotional well-being. As a function of both urbanization and increased economic means, children’s collectivistic family responsibilities for essential household chores have declined as the importance of schoolwork has increased.

Vehicular ad hoc network is a multihop mobile wireless communication network that can realize many vehicle-related applications through multitop communication. In the open wireless communication environment, security and privacy protection are important contents of VANET research. The most basic method of VANET privacy protection is anonymous authentication. Even through, there are many existing schemes to provide anonymous authentication for VANETs. Many existing schemes suffer from high computational cost by using bilinear pairing operation or need the assistance of the trust authorities (...) during the authentication process or rely on an ideal tamper-proof device, which requires very strong security assumption. In this study, an anonymous authentication and key negotiation scheme by using private key and group key is proposed, which is based on pseudonym using the nonsingular elliptic curve. In this scheme, there is no third party trust center to participate in the authentication, there is no need to query the database, and there is no need of the local database to save the identity information of many vehicles, which reduce the storage space and the authentication time compared with other schemes. The proposed scheme only needs realistic TPDs. In the proposed scheme, TPDs do not need to preinstall the system key as many other schemes do; hence, the failure of a single TPD does not affect the security of the entire system. The security of the scheme is proved under the random oracle model. Compared with the related schemes using bilinear pairings, the computational cost and communication cost of the proposed scheme are reduced by 82% and 50%, respectively. (shrink)

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)

This study aimed to investigate the factor structure and measurement invariance of the Brief Symptom Inventory-18 among Chinese adults. A sample comprising 1,839 adults from four cities in Shaanxi province completed the BSI-18 and background information. The best-fitting factor structure model of the BSI-18 was verified by confirmatory factor analyses, and multigroup confirmatory factor analyses were performed to test the measurement invariance. The results indicated that the three-factor bi-factor model fitted the current data best. The configural, metric, scalar, and strict (...) invariance models all had acceptable model fit indexes across genders, and the configural, metric, scalar invariance models with different living areas and educational levels were all acceptable. Overall, the three-factor bi-factor model of the BSI-18 shows a good fit for use with Chinese adults, making it a viable tool for effectively measuring the mental health of Chinese adults. (shrink)

PurposeThe purpose of this study was to introduce an orthogonal experimental design to improve the efficiency of building and optimizing models for freezing of gait prediction.MethodsA random forest model was developed to predict FOG by using acceleration signals and angular velocity signals to recognize possible precursor signs of FOG. An OED was introduced to optimize the feature extraction parameters.ResultsThe main effects and interaction among the feature extraction hyperparameters were analyzed. The false-positive rate, hit rate, and mean prediction time were 27%, (...) 68%, and 2.99 s, respectively.ConclusionThe OED was an effective method for analyzing the main effects and interactions among the feature extraction parameters. It was also beneficial for optimizing the feature extraction parameters of the FOG prediction model. (shrink)

Chapter 27 of the ancient Chinese text the Zhuangzi describes three kinds of language: yuyan, zhiyan, and chongyan. Wang Fuzhi first coined the term ‘sanyan ’ or ‘tripartite-language’ to emphasize their overlapping characteristics and incorporate them into a cohesive approach to the text. Sanyan has been used consistently in interpreting the Zhuangzi since the earliest compilation of its extant version and continues to inform academic publications today. Based on descriptions found in the Zhuangzi's ‘miscellaneous chapters’ and on contemporary scholarship, (...) I will explain how this model of sanyan functions and then how it facilitates philosophical reading of the Zhuangzi. Understanding the Zhuangzi's metaphorical language through sanyan lends access into the interrelated semantic field of the pre-Qin philosophical canon and helps unravel Zhuangzi's often-cryptic philosophical expressions.

Among all the post-Zhuang Zi schools of Zhuang Zi philosophy, the Shu Zhuang school was the school of most direct descent. Its works included the twelve "chapters": "Qiushui", "Zhi le", "Da sheng", "Shan mu", "Tian Zifang," "Zhi beiyou," "Geng Sang Chu," "Xu wugui," "Ze yang," "Wai wu", "Yuyan", and "Lie Yukou." From the intellectual content and linguistic style of these essays, the works of the Shu Zhuang school appear to belong to a chronologically earlier category of the outer and (...) miscellaneous chapters. The chief characteristic of this category of writings is that they inherited and basically developed the meaning of the ideas of the "inner chapters." They provided a more careful and detailed explanation of Zhuang Zi's theories of original source, true knowledge, and the equality of things, and they also developed other key ideas of Zhuang Zi, including his idea of human life. The Shu Zhuang school did, to a certain extent, reform and develop Zhuang Zi's ideas, but there is no major breakthrough from his ideas, and, basically, the work of this school was to elaborate but not to innovate. The works of the Shu Zhuang school served as the major corpus of reference material for the study of Zhuang Zi's ideas. In Part 2 of this book, where we developed an interpretaion of Zhuang Zi's ideas, we have already touched on some of these essays written by the people of the Shu Zhuang school. Let us now analyze and critique the ideas of this school in a more concentrated fashion. (shrink)
