A novel fingerprint recognition method based on a Siamese neural network.Yang Zhang,Lingyi Huang,Shanshan Gu,Jianpeng Yu,Xiao Wu,LixinZhai,Xiaomin Tian,Zhong Yang,Yizhi Wang &Zihao Li -2022 -Journal of Intelligent Systems 31 (1):690-705.detailsFingerprint recognition is the most widely used identification method at present. However, it still falls short in terms of cross-platform and algorithmic complexity, which exerts a certain effect on the migration of fingerprint data and the development of the system. The conventional image recognition methods require offline standard databases constructed in advance for image access efficiency. The database can provide a pre-processed image via a specific method that probably is compatible merely with the specific recognition algorithm. Then, the specific recognition (...) algorithm starts the process of retrieving these specific pre-proessing images for recognition and inevitably will be blocked from other datasets. The proposed method in this research designed an embedded image processing algorithm based on a Siamese neural network in the recognition method that allows the proposed method to recognize images from any source without constructing a database for image storage in advance. In this research, the proposed method was applied to fingerprint recognition and evaluation of the proposed method was evaluated. The results showed that the accuracy of the proposed algorithm was up to 92%, and its F1 score was up to 0.87. Compared with the conventional fingerprint matching methods, its significant advantage in the FRR, FAR, and CR jointly indicated the remarkable correct recognition rate of the proposed method.

Underwater Acoustic Image Encoding Based on Interest Region and Correlation Coefficient.LiuLixin,Guo Feng &Wu Jinqiu -2018 -Complexity 2018:1-13.detailsIt is difficult for the conventional image compression method to achieve good compression effect in the underwater acoustic image, because the UWAI has large amount of noise and low correlation between pixel points. In this paper, fractal coding is introduced into UWAI compression, and a fractal coding algorithm based on interest region is proposed according to the importance of different regions in the image. The application problems of traditional quadtree segmentation in UWAIs was solved by the range block segmentation method (...) in the coding process which segmented the interest region into small size and the noninterest region into large size and balanced the compression ratio and the decoded image quality. This paper applies the classification, reduction codebook, and correlation coefficient matching strategy to narrow the search range of the range block in order to solve the problem of the long encoding time and the calculation amount of encoding process is greatly reduced. The experimental results show that the proposed algorithm improves the compression ratio and encoding speed while ensuring the image quality of important regions in the UWAI. (shrink)

Champion Position Analysis in Short Track Speed Skating Competitions From 2007 to 2019.Lixin Sun,Tianxiao Guo,Fei Liu &Kuan Tao -2021 -Frontiers in Psychology 12.detailsPurpose: Short track speed skating is a racing sport with racing tactics are equally crucial to speed and technical skating skills. Therefore, to investigate the relationship between starting and finishing positions for elite skaters and subsequently, explore pacing patterns for champions are necessary.Methods: To investigate a pattern of effective tactical positioning strategy, Kendall’s tau-b correlations between starting and finishing position were calculated, with 500 m races having the most positive correlation.Results: Furthermore, starting position distributions of winners in each round, as (...) well as the fluctuations in champion starting positions across rounds were analyzed. Our findings showed that skaters on the first track were inclined to win the rounds in 500, 1,000, and 1,500 m, and the differences between starting and finishing positions for champions were minimized in semi-finals. Meanwhile, the pacing patterns were gaining more fluctuations by the increase of race distances for champions, as the average standard deviation of lap rankings equaled 0.90, 1.15, and 2.21 for 500, 1,000, and 1,500 m races, respectively.Conclusion: In conclusion, elite skaters should adopt flexible tactics at the lowest cost of energy consumption. The overall variability of lap ranking in long-distance races were distinctly higher than it in short distance. (shrink)
Mixed Feelings About Supervisors: The Effect of LMX Ambivalence on Supervisor-Directed Behaviors.Lixin Chen,Qingxiong Weng,Anastasiia Popelnukha &Hui Jiang -forthcoming -Journal of Business Ethics:1-20.detailsIntegrating norms of reciprocity, affect theory of social exchange, and ambivalence literature, we investigated how leader-member exchange (LMX) ambivalence influences employees’ interpersonal behaviors toward supervisors. Study 1, with a time-lagged field method, revealed that LMX ambivalence was positively related to _both_ employee-rated supervisor-directed helping and deviant behaviors and that such relationships were mediated by emotional ambivalence toward supervisors. We also confirmed the amplification effects of workplace gossip about supervisors (WGS). Specifically, while receiving more positive WGS (PWGS) or less negative WGS (...) (NWGS) could strengthen the positive relationship between emotional ambivalence and supervisor-directed helping behaviors, receiving less PWGS or more NWGS would accentuate the positive effect of emotional ambivalence on supervisor-directed deviant behaviors. Study 2 replicated our results with a scenario-based method and offered evidence for the mediating effect of emotional ambivalence toward supervisors. Study 3 included supervisor-rated helping and deviant behavior and a subjective measure of emotional ambivalence and again confirmed the mediating role of emotional ambivalence. Our findings extend knowledge of the interpersonal consequences of LMX ambivalence. (shrink)
Authoritarian-Benevolent Leadership and Employee Behaviors: An Examination of the Role of LMX Ambivalence.Lixin Chen &Qingxiong Weng -2023 -Journal of Business Ethics 186 (2):425-443.detailsAccording to social information processing theory and conservation of resource theory, we examine whether and how authoritarian-benevolent leadership influences employees’ proactive work behaviors (PWBs) and unethical pro-organizational behaviors (UPBs). Study 1, a survey of 351 participants, revealed that authoritarian-benevolent leadership was positively related to LMX ambivalence, and that LMX ambivalence was negatively related to employees’ PWBs as well as UPBs. Further, the results showed that LMX ambivalence mediated the relationship between authoritarian-benevolent leadership and employees’ PWBs as well as UPBs. We (...) also found that dialectical thinking negatively moderated the effect of authoritarian-benevolent leadership on employee LMX ambivalence. Study 2, using manipulations in the form of scenarios, examined the mediating effect of LMX ambivalence linking authoritarian-benevolent leadership with employees’ PWBs and UPBs. We discussed the theoretical and practical implications of our findings. (shrink)
Celebrity Endorsement, Brand Equity, and Green Cosmetics Purchase Intention Among Chinese Youth.Zhai Lili,Abdullah Al Mamun,Naeem Hayat,Anas A. Salamah,Qing Yang &Mohd Helmi Ali -2022 -Frontiers in Psychology 13.detailsThe study examined the effect of celebrity attractiveness, celebrity trustworthiness, and celebrity cause fit on the attitude toward green cosmetics. This was followed by the effect of brand awareness, brand associations, brand loyalty, perceived quality, brand credibility on brand equity, including the impact of attitude toward green cosmetics and brand equity on the willingness to purchase green cosmetics among of young Chinese consumers. This study adopted a cross-sectional design and collected quantitative data from 301 respondents using a structured questionnaire, which (...) was distributed online using various social media platforms. It was found that celebrity attractiveness, celebrity trustworthiness, and celebrity cause-fit had a significant impact on the attitudes toward green cosmetic, while brand loyalty, perceived quality, and brand credibility substantially affected brand equity. Moreover, the attitudes toward green cosmetics and brand equity had a strong impact on the willingness to purchase green cosmetics. To increase the sales for green cosmetics, the advertisements for it should have appeal, trustworthiness, and cause-fit celebrities to improve consumers’ attitudes and willingness to purchase green cosmetics. Finding of this study provide a guideline for green cosmetic manufacturers, to direct their resources to enhance brand loyalty, credibility, and perceived quality of the product they produce by highlighting the difference between conventional and green cosmetics.

Dance Movement Recognition Based on Feature Expression and Attribute Mining.XianfengZhai -2021 -Complexity 2021:1-12.detailsThere are complex posture changes in dance movements, which lead to the low accuracy of dance movement recognition. And none of the current motion recognition uses the dancer’s attributes. The attribute feature of dancer is the important high-level semantic information in the action recognition. Therefore, a dance movement recognition algorithm based on feature expression and attribute mining is designed to learn the complicated and changeable dancer movements. Firstly, the original image information is compressed by the time-domain fusion module, and the (...) information of action and attitude can be expressed completely. Then, a two-way feature extraction network is designed, which extracts the details of the actions along the way and takes the sequence image as the input of the network. Then, in order to enhance the expression ability of attribute features, a multibranch spatial channel attention integration module based on an attention mechanism is designed to extract the features of each attribute. Finally, using the semantic inference and information transfer function of the graph convolution network, the relationship between attribute features and dancer features can be mined and deduced, and more expressive action features can be obtained; thus, high-performance dance motion recognition is realized. The test and analysis results on the data set show that the algorithm can recognize the dance movement and improve the accuracy of the dance movement recognition effectively, thus realizing the movement correction function of the dancer.

Risk Prediction and Response Strategies in Corporate Financial Management Based on Optimized BP Neural Network.MeijiaZhai -2021 -Complexity 2021:1-10.detailsThis paper mainly analyzes the theories related to the financial risk of the company and combines the principles of principal component analysis, particle swarm optimization algorithm, and artificial neural network to derive the financial risk index system of the company. To improve the accuracy of financial risk prediction, principal component analysis and particle swarm algorithm are applied to optimize the BP neural network model, the input data of the prediction model is improved, and the optimal initial weights and thresholds are (...) given to the BP neural network by using particle swarm algorithm search, whereby the financial risk prediction model of particle swarm optimization BP neural network is constructed. The empirical results show that the model constructed by BP neural network not only has a high accuracy rate for static financial risk evaluation but also has a better prediction effect. After training and testing, the BP neural network-based enterprise financial risk evaluation model can accurately determine the existing financial situation of enterprise financial management and has a good prediction effect.

Intermittent Time-Varying Formation Control for High-Order Networked Agents Subject to Discontinuous Communications.Lixin Wang,Zhe Luo,Xiaoqiang Li,Xinsan Li &Xiaogang Yang -2021 -Complexity 2021:1-14.detailsThis paper investigates the leaderless and leader-follower time-varying formation design and analysis problems for a group of networked agents subject to discontinuous communications. Firstly, a leaderless time-varying formation control protocol is proposed via the intermittent control strategy, where the control input of each agent is constructed by the distributed local state information and formation instructions in the communication time unit, but it is zero in the noncommunication time unit. Then, an explicit formulation of the formation center function is determined to (...) describe the formation movement trajectory of the whole networked agents. Leaderless time-varying formation design and analysis with discontinuous communications are given in the form of linear matrix inequalities. Moreover, the main results of the leaderless cases are extended to the leader-follower cases. Finally, two numerical examples are provided to illustrate the theoretical results of leaderless and leader-follower cases, respectively. (shrink)
Perceptions of long-term care, autonomy, and dignity, by residents, family and caregivers: The beijing experience.XiaomeiZhai &Ren Zong Qiu -2007 -Journal of Medicine and Philosophy 32 (5):425 – 445.detailsThis article documents the results of a study on the perceptions of long-term elder care in Beijing in the People's Republic of China by those most intimately involved. The study asked a sample of elderly, family members, and health care professionals, all of whom are involved in care at a variety of long-term care facilities in Beijing, about their perceptions of the care given at these facilities from their particular standpoints as regards issues such as the quality and ideal location (...) of care, decision-making regarding the care receiving, who should be responsible for the financing of care, and the meaning of dignity for the elderly in these facilities. The results showed adherence to traditional family values at least on one level regarding the ideal location of care being with the family and in the home, but also the desire to pass on financing of long-term care facilities and the health care they provide the elderly on to the government. These results are not altogether surprising, but they also clearly demonstrate the larger conflict between traditional views about morality and economic considerations regarding health care financing in the China.

No ethical divide between China and the West in human embryo research.XiaomeiZhai,Vincent Ng &Reidar Lie -2016 -Developing World Bioethics 16 (2):116-120.detailsThis is a discussion of the reaction to the recent research article publication in the journal Protein & Cell by a group of scientists at Sun Yat-sen University using the CRISPR/Cas9 technique on editing non-viable human zygotes. Many commentators condemned the Chinese scientists for overstepping ethical boundaries long accepted in Western countries and accused China of having lax regulations on genomic research in general. We argue that not only did this research follow strict ethical standards and fully comply with current (...) regulations, but China also has a well-developed regulatory framework governing such research comparable to many developed countries. We see the reactions among Western commentators as a misunderstanding of the current situation and an expression of a lack of willingness to acknowledge China as an equal partner in the international debate about proper limits to the development of new biotechnologies.

Bentham’s Exposition of Common Law.XiaoboZhai -2017 -Law and Philosophy 36 (5):525-560.detailsBentham is a severe critic of common law, denouncing it as ‘sham law’. Bentham’s denunciation of common law as ‘sham law’ is, however, an evaluative censure, not a descriptive account. A realistic account of the nature of common law can be constructed from his writings. According to this account, first, common law is a collection of authoritative mandates. Second, judicial decisions do not evidence common law; on the contrary, judges, through their decisions, create common law by means of legalizing both (...) customs and single actions. Common law is not, therefore, immemorial, nor did it originate in the people’s consent. Third, stare decisis is necessary for common law to fulfil the function of law, but it has no independent value: it is the principle of utility alone that explains, justifies, and decides the use of stare decisis.

The Need for Cognition on Earthquake Risk in China Based on Psychological Distance Theory.Shasha Li,GuofangZhai,Chenjing Fan,Jing Chen &Li Li -2020 -Complexity 2020:1-14.detailsThere is a high need for cognition on earthquake risk to improve the public’s risk knowledge and risk awareness, so that they can make right decisions and take quick actions regarding mitigation measures and adjustments. In this study, search engine query data from the Baidu Index were extracted to reveal the information search behaviors of the Chinese public regarding the earthquake risk from 2010 to 2012. The data were also analyzed to discuss the characteristics of need for cognition on a (...) nationwide scale and over the long term. The results showed that graphic representations of need for cognition adhere to a “half-peak pattern” before and after earthquake events and dimensions in psychological distance theory, such as temporal distance, spatial distance, and social distance influence the need for cognition on earthquake risk that was the time and spatial discount effect. The implications for theory and practice regarding risk communication and management are discussed and concluded. (shrink)
Mental fatigue decreases complexity: Evidence from multiscale entropy analysis of instantaneous frequency variation in alpha rhythm.YawenZhai,Yan Li,Shengyi Zhou,Chenxu Zhang,Erping Luo,Chi Tang &Kangning Xie -2022 -Frontiers in Human Neuroscience 16:906735.detailsMental fatigue (MF) jeopardizes performance and safety through a variety of cognitive impairments and according to the complexity loss theory, should represent “complexity loss” in electroencephalogram (EEG). However, the studies are few and inconsistent concerning the relationship between MF and loss of complexity, probably because of the susceptibility of brain waves to noise. In this study, MF was induced in thirteen male college students by a simulated flight task. Before and at the end of the task, spontaneous EEG and auditory (...) steady-state response (ASSR) were recorded and instantaneous frequency variation (IFV) in alpha rhythm was extracted and analyzed by multiscale entropy (MSE) analysis. The results show that there were significant differences in IFV in alpha rhythm either from spontaneous EEG or from ASSR for all subjects. Therefore, the proposed method can be effective in revealing the complexity loss caused by MF in spontaneous EEG and ASSR, which may serve as a promising analyzing method to mark mild mental impairments.

Emotional Creativity Improves Posttraumatic Growth and Mental Health During the COVID-19 Pandemic.Hong-KunZhai,Qiang Li,Yue-Xin Hu,Yu-Xin Cui,Xiao-Wei Wei &Xiang Zhou -2021 -Frontiers in Psychology 12.detailsEmotional creativity refers to a set of cognitive abilities and personality traits related to the originality of emotional experience and expression. Previous studies have found that emotional creativity can positively predict posttraumatic growth and mental health. The outbreak of coronavirus disease 2019 (COVID-19) has posed great challenges to people’s daily lives and their mental health status. Therefore, this study aims to address the following two questions: whether emotional creativity can improve posttraumatic growth and mental health during the COVID-19 pandemic and (...) how it works. To do this, a multiple mediation model has been proposed, which supposes that emotional creativity is associated with posttraumatic growth and mental health through perceived social support and regulatory emotional self-efficacy. The study involved 423 participants from multiple regions with different COVID-19 involvement levels. Participants were asked to complete a questionnaire with six parts, which included Emotional Creativity Inventory (ECI), Regulatory Emotional Self-Efficacy Scale (RES), Stress-Related Growth Scale-Short Form (SRGS-SF), Multidimensional Scale of Perceived Social Support scale (MSPSS), Brief Symptom Inventory-18 scale (BSI-18), and COVID-19-related life events questionnaire. Path analysis used to examine the mediation model indicated that under the control of COVID-19-related life events and age, perceived social support mediated a positive association between emotional creativity and posttraumatic growth as well as a negative association between emotional creativity and all mental health problems, including somatization, depression, and anxiety. Regulatory emotional self-efficacy mediates the association between emotional creativity and posttraumatic growth, emotional creativity and anxiety, and emotional creativity and depression. The results suggest that emotional creativity plays an important role in coping with stressful events related to COVID-19. Furthermore, these results might provide a better understanding of the possible paths through which emotional creativity is related to psychological outcomes, such as mental health and posttraumatic growth.

The Variation of Chinese Literature and the Formation of World Literature.Shunqing Cao &LuZhai -2022 -Cultura 19 (2):7-23.detailsIn "The Variation of Chinese Literature and the Formation of World Literature" Shunqing Cao and LuZhai discuss how Chinese works of literature entered other countries' literary circles through variation, and became an essential part of world literature. Both ancient Chinese literature and contemporary Chinese literature have undergone textual circulation, language translation and cultural filtering before becoming part of world literature, all of which are the reasons why literary variation occurs. According to Cao andZhai, the occurrence of (...) variation is a key factor for Chinese literature to become world literature, and an important foundation for the formation of world literature. A country's literature absorbs the characteristics of other countries' literature through variation, thus adapting to the cultural background and reading habits of other countries' readers in terms of language and style, in order to enter the world literature market. Variation may lead to a certain loss of nationality in literary works, and result in significant differences from the original texts. However, the formation of world literature does not come at the cost of eliminating nationality; variation facilitates the formation of world literature. (shrink)

Workplace Guanxi: Its Dispositional Antecedents and Mediating Role in the Affectivity–Job Satisfaction Relationship. [REVIEW]QingguoZhai,Margaret Lindorff &Brian Cooper -2013 -Journal of Business Ethics 117 (3):541-551.detailsThis paper examines dispositional sources of workplace guanxi and the mediating role of workplace guanxi on the affectivity and job satisfaction relationship. Data were collected from 808 respondents in multiple industries in a city in China’s northeast. The study found that both positive affectivity and negative affectivity have an effect on supervisor–subordinate guanxi and co-worker guanxi, which supports the proposition that workplace guanxi has a dispositional source. Supervisor–subordinate guanxi has a positive relationship with job satisfaction, although co-worker guanxi is not (...) significantly related to job satisfaction. The research also found a mediating role of supervisor–subordinate guanxi on the affectivity and job satisfaction relationship, which suggests that supervisor–subordinate guanxi can extend the influence of affectivity to job satisfaction. Taken together, these results suggest that in a high power distance country such as China, supervisor–subordinate guanxi plays a more important role than co-worker guanxi in influencing job satisfaction. Theoretically, this study suggests the as yet unexplored possibility of dispositional antecedents of workplace guanxi and the role of workplace guanxi on the relationship between dispositions and workplace attitudes such as job satisfaction.

Impact of absent crowds on technical and physical performances in the Chinese Soccer Super League.Junjin Chen,ShuaishuaiZhai,Zenghui Xi,Peilun Li &Shuolin Zhang -2022 -Frontiers in Psychology 13.detailsPurposeSpectators have a significant impact on match performances in soccer, but to what extent crowd support contributes to the technical and physical performances remains unclear. This study aimed to investigate the differences in terms of technical and physical performances with and without spectators; and identify the key factors differentiating between win and loss when playing with and without the presence of an audience.MethodsOur study examined 794 performance records from 397 matches during the 2019–2020 seasons in the Chinese Soccer Super League. (...) The least absolute shrinkage and selection operator -logistic regression was utilized to select significant predictors. Using an independent t-test and the Mann–Whitney non-parametric test explores the difference between matches with and without spectators. Key factors between win and loss were explored using univariate and multivariate logistic regression analyses.ResultsOur study found that cross, shots, and shot accuracy displayed decreasing trends whereas sprint distances presented an increasing trend without spectators comparing with the crowd support. Moreover, the above three technical variables were the main factors differentiating between wins and losses. Similarly, team and opponent quality remained important potential factors affecting the match outcome.ConclusionMatch outcome or team performance is determined by a myriad of factors, but there are clear differences in technical and physical performances between matches with and without the presence of an audience. Similarly, our study provides a better explanation for the impact of crowd support on match performances whereby coaches can deploy players and adjust match strategies for ultimate success. (shrink)
