In this paper, by using the adaptive dynamics approach, we investigate how the adaptive evolution of defense ability promotes the diversity of prey species in an initial one-prey–two-predator community. We assume that the prey species can evolve to a safer strategy such that it can reduce the predation risk, but a prey with a high defense ability for one predator may have a low defense ability for the other and vice versa. First, by using the method of critical function analysis, (...) we find that if the trade-off is convex in the vicinity of the evolutionarily singular strategy, then this singular strategy is a continuously stable strategy. However, if the trade-off is weakly concave near the singular strategy and the competition between the two predators is relatively weak, then the singular strategy may be an evolutionary branching point. Second, we find that after the branching has occurred in the prey strategy, if the trade-off curve is globally concave, then the prey species might eventually evolve into two specialists, each caught by only one predator species. However, if the trade-off curve is convex–concave–convex, the prey species might eventually branch into two partial specialists, each being caught by both of the two predators and they can stably coexist on the much longer evolutionary timescale.

Self-serving leadership is a form of unethical leadership behavior that has destructive effect on its targets and the overall organization. Adopting a social cognition perspective, this study expands our knowledge of its adverse effect and the way to mitigate the effect. Integrating two sub-theories of social cognition, we propose a theoretical model wherein self-serving leadership hinders team creativity through psychological safety as well as knowledge hiding, with task interdependence acting as a contextual condition. Results from a sample of 107 R&D (...) teams revealed that self-serving leadership not only reduced team psychological safety, but also induced team knowledge hiding, both of which ultimately affected team creativity. The presence of high task interdependence buffered the destructive effect of self-serving leadership on team creativity via team psychological safety as well as the indirect effect via knowledge hiding.

BackgroundMental stress and imbalance of its two neural stress systems, the autonomic nervous system and the hypothalamic–pituitary–adrenal axis, are associated with chronic prostatitis/chronic pelvic pain syndrome and erectile dysfunction. However, the comprehensive analyses of psychological stress and stress systems are under-investigated, particularly in CP/CPPS patients complicated by lower urinary tract symptoms and ED.Materials and methodsParticipants were 95 patients in CP/CPPS+ED group, 290 patients in CP/CPPS group, 124 patients in ED group and 52 healthy men in control group. The National Institutes (...) of Health Chronic Prostatitis Symptom Index, the International Index of Erectile Function-5 and the International Prostate Symptom Score were used for assessing the disease severity of CP/CPPS, LUTS and ED. Psychometric self-report questionnaires including the Beck Anxiety Inventory, Perceived Stress Scale, Type A Personality Test and Symptom Checklist 90 were completed for distress from physical symptoms. Twenty-five subjects per group were randomly selected for further investigating the changes of the HPA axis and ANS. Saliva samples were taken on 3 consecutive days at 8 specific times with strict reference to time of morning awakening for evaluation of free cortisol. Heart rate variability as marker of the ANS was measured using 24 h electrocardiography, and time-and frequency-domain variables were analyzed.ResultsThe BAI and SCL-90 scores were significantly higher in the CP/CPPS+ED, CP/CPPS and ED groups compared with the control group. The PSS scores of both groups with ED were significantly higher than the control group. Compared with the CP/CPPS group, the differences of PSS, SCL-90 and TAPT scores were statistically significant in CP/CPPS+ED patients. The IPSS scores were shown to have significantly positive correlations with BAI, PSS and SCL-90 in the CP/CPPS patients. However, in all subjects, the IIEF-5 scores were shown to have significantly negative correlations with BAI, PSS, SCL-90 and quality of life score in NIH-CPSI. Cortisol awakening response parameters and diurnal cortisol levels did not significantly vary between the four groups. Time-dependent parameters of HRV also did not differ significantly across groups. In the frequency domain analysis, low frequency was significantly lower in ED patients when compared with CP/CPPS+ED patients and healthy controls, high frequency power was significantly higher in healthy controls compared to patients with ED, CP/CPPS and CP/CPPS+ED, and the CP/CPPS+ED group had significantly higher LF/HF ratio than the control group.ConclusionCP/CPPS and ED patients score exceedingly high on most psychosocial variables. The symptom scores of LUTS and ED positively correlate with the severity of psychological stress. Our findings also suggest that the ANS sympathovagal imbalance is associated with ED and LUTS in CP/CPPS, whereas HPA axis activity is not. (shrink)

Because they are key components of aircraft, improving the safety, reliability and economy of engines is crucial. To ensure flight safety and reduce the cost of maintenance during aircraft engine operation, a prognostics and health management system that focuses on fault diagnosis, health assessment, and life prediction is introduced to solve the problems. Predicting the remaining useful life is the most important information for making decisions about aircraft engine operation and maintenance, and it relies largely on the selection of performance (...) degradation features. The choice of such features is highly significant, but there are some weaknesses in the current algorithm for RUL prediction, notably, the inability to obtain tendencies from the data. Especially with aircraft engines, extracting useful degradation features from multisensor data with complex correlations is a key technical problem that has hindered the implementation of degradation assessment. To solve these problems, deep learning has been proposed in recent years to exploit multiple layers of nonlinear information processing for unsupervised self-learning of features. This paper presents a deep learning approach to predict the RUL of an aircraft engine based on a stacked sparse autoencoder and logistic regression. The stacked sparse autoencoder is used to automatically extract performance degradation features from multiple sensors on the aircraft engine and to fuse multiple features through multilayer self-learning. Logistic regression is used to predict the remaining useful life. However, the hyperparameters of the deep learning, which significantly impact the feature extraction and prediction performance, are determined based on expert experience in most cases. The grid search method is introduced in this paper to optimize the hyperparameters of the proposed aircraft engine RUL prediction model. An application of this method of predicting the RUL of an aircraft engine with a benchmark dataset is employed to demonstrate the effectiveness of the proposed approach. (shrink)

Green consumption values have been shown to motivate consumers to engage in green consumption practices. However, surprisingly little research has examined how green consumption values develop in young people. In the current study, we employed ecological socialization theory as a framework to investigate the process by which parents’ green consumption values shape similar values in their young adolescents. In Study 1, data from 722 Chinese families that included an early adolescent showed that both mothers’ and fathers’ green consumption values were (...) positively associated with early adolescents’ green consumption values, and this association was mediated by each parent’s environmentally responsible consumption behavior. Study 2 replicated the results of Study 1 using two waves of matched parent-adolescent data collected a month apart from another group of 477 Chinese families. Furthermore, Study 2 showed that the mediation process identified in Study 1 was evident only when there was a close parent–child relationship. These findings have implications for cultivating the green consumption values of today’s youth. The results also have heuristic value for future research on the ecological socialization and inter-generational transmission of pro-environmental values. (shrink)

Government subsidies have a direct impact on firms' innovation strategies. The game relationship between the government, the subsidized firm and its competitors under different subsidy strategies affects firms' innovation behavior and thus innovation performance. This paper uses a dynamic evolutionary game theory approach based on cost-benefit differences to analyse the mechanisms by which government subsidy strategies affect firms' innovation strategies. It is found that the marginal benefits of a firm's innovation strategy will directly affect the game outcome, indicating that the (...) choice of innovation strategy depends on the maximization of individual firm's interests. At the same time, a firm's innovation strategy is influenced by the firm's own innovation ability and competitors' innovation strategy, and there are two game equilibria. Government subsidies have a positive contribution to the innovation strategy choice of subsidized firms, but have a crowding-out effect on non-subsidized competing firms. The strength of the penalty, the marginal revenue of the subsidized firms' rational use of government subsidies and the competitors' strategic choices will directly affect the game outcome. (shrink)

Given the significance of teachers’ professional success in the adequacy of education, exploring the determinants of this variable appears crucial. To address this need, this inquiry inspected the role of well-being and emotion regulation in Chinese EFL teachers’ professional success. For this purpose, 357 Chinese EFL teachers were selected to answer three pre-designed questionnaires. Structural equation modeling using Smart-PLS was implemented to analyze teacher participants’ responses. The structural model revealed a strong, favorable connection between well-being, emotion regulation, and professional success. (...) The model also demonstrated that both well-being and emotion regulation were highly influential in Chinese EFL teachers’ professional success. The potential implications for EFL teachers, teacher educators, and educational authorities are further discussed. (shrink)

In recent years, there has been a growing interest in scholars and practitioners to explore the factors that lead to an improvement in Students’ psychological wellbeing. Due to the tough challenges faced by students during their academic life, severe issues of stress, anxiety, and other mental health issues emerge, which affect their academic performance and have a long-lasting impact on their future careers. The pandemic accelerates the stress levels, anxiety, and mental issues of students. The main purpose of this study (...) was to explore how music education impacts on Students’ psychological wellbeing and academic performance. This study also investigates the mediating effect of self-esteem and self-efficacy. To the best of our knowledge, there has been little to no study exploring the relationship of music education on the psychological wellbeing and performance of students, especially from the perspective of Asian countries. This study was conducted in undergraduate and graduate institutions of China. This study was quantitative in nature and data were collected from 319 respondents. The structural equation modeling technique was employed for data analysis. Results reveal that music education has a significant positive impact on psychological wellbeing, which improves Students’ academic performance. Moreover, psychological wellbeing also has a significant and positive impact on Students’ academic performance. Self-efficacy and self-esteem significantly mediate the relationship between music education and psychological wellbeing. The findings of this study open new avenues for future research in music education and psychological wellbeing. This study suggests that the policymakers and practitioners should make such policies that encourage educational institutes to adopt music education to improve the psychological wellbeing of students.

The potential negative impacts of biological pest control on non-target species have become the focus of a contentious debate. In this article, we use examples from both classical and augmentative biological control of fruit fly pests in Hawaii to address several important factors in assessing non-target risks of fruit fly parasitoids. Several fruit fly parasitoids have been introduced to Hawaii and contribute substantially to the reduction of pest populations in the state's farms and forests. However, an historical lack of host-specificity (...) testing of these parasitoids with non-target species has raised concerns about their impact on non-pest fruit flies, including some flies deliberately introduced for biological control of weeds and others that are endemic Hawaiian species. When developing protocols to assess risks of introduced fruit fly parasitoids, we need first to define an appropriate range of species against which host specificity should be tested. For assessing susceptibility of a non-target species to parasitoids, behavioral tests are as important as suitability tests. Experimental factors, such as host-exposure substrate, absence or presence of preferred hosts, and laboratory vs. natural conditions, are shown to affect the results of host-specificity tests and risk analysis. Still, assessing long-term, indirect ecological impacts of parasitoids and weighing potential risks and benefits in multiple dimensions (besides dollar values) remains a challenge to environmentalists, conservationists, applied ecologists, and biocontrol practitioners.

Exploring the amplitude modulation phenomenon of chaotic signal has become a subject of great concern in recent years. This paper mainly concentrates on the preliminary study on amplitude modulation principle of a chaotic system. First, two 3D chaotic systems with quadratic product terms are introduced for studying the amplitude modulation phenomenon of chaotic signal. It is found that the signal amplitude of the first system can be controlled by partial quadratic coefficient. But for the second system, none of nonlinear coefficient (...) can be employed to control the signal amplitude. Then, the amplitude modulation principle of chaotic system is preliminarily studied by exploring the intrinsic relationship between nonzero equilibrium point and phase space trajectory, and it is further validated by introducing unified parameter to the two 3D chaotic systems. As a necessary condition, the principle provides a feasible and simple method for constructing and analyzing an amplitude modulation chaotic system. (shrink)

We design and implement an intelligent IoT-based motion monitoring system to realize the monitoring of three important parameters, namely, the type of movement, the number of movements, and the period of movement in physical activities, and optimize the system to support the simultaneous use by multiple users. Considering the motion monitoring scenario for smart fit, the framework of an IoT-based motion monitoring system is proposed. The framework contains components such as active acquisition nodes, wireless access points, data processing servers, and (...) terminals. In terms of algorithm optimization, research related to active pattern recognition and periodic calculation methods is conducted. For active pattern recognition, two types of classification algorithms with different complexity are proposed based on Support Vector Machine and deep neural networks, respectively, to adapt to scenarios with different computational capabilities. For period calculation, a method based on over-zero detection and wavelet transform is proposed to count the number of actions and calculate the period of each action. In 100 times action cycle calculation experiments, the count statistic calculation method achieves 100% calculation accuracy and the active cycle calculation results are close to the real value, which proves the effectiveness of the cycle calculation method. The system provides a multiuser-oriented communication method and realizes accurate and reliable human movement monitoring, which has a wide application prospect in the fields of physical education and rehabilitation training.

In 2004 The New York Times launched a weekly Times Supplement with Taiwan’s United Daily News. This article aims to explore non-lexicalized allusion variation between TS headlines and NYT headlines as a discourse strategy. A textual survey was conducted on a corpus comprising 605 TS news articles and their corresponding NYT articles. Non-lexicalized allusions were identified and explored within a reader-oriented approach. And a stylistic analysis was performed to explore cognitive, pragmatic, and rhetorical roles of non-lexicalized allusions in the corpus. (...) The results show that non-lexicalized allusions occur in far fewer TS than NYT headlines. The allusion downsizing increases the accessibility of TS headlines to general TS readers at the cost of cultural diverseness and stylistic expressiveness in the headline language, making the language of TS headlines stylistically more restricted and culturally less Western. NYT headline language exemplifies English as a native language, whereas TS headline language is a specific genre of English as an international language. This article also discusses cultural implications of non-lexicalized allusions for EIL learning. It is pointed out that EIL is an integration of elements of all varieties of English involved in international or intercultural discourse. The cultural knowledge behind non-lexicalized allusions dealt with in this article represents one such element of EIL. (shrink)

Using a sample of Chinese listed firms for the period of 2004–2010, this study examines the impact of religion on corporate philanthropic giving. Based on hand-collected data of religion and corporate philanthropic giving, we provide strong and robust evidence that religion is significantly positively associated with Chinese listed firms’ philanthropic giving. This finding is consistent with the view that religiosity has remarkable effects on individual thinking and behavior, and can serve as social norms to influence corporate philanthropy. Moreover, religion and (...) corporate philanthropic giving have a significantly weaker (less pronounced) positive association for state-owned enterprises than for non-state-owned enterprises. The results are robust to a variety of sensitivity tests. Our results highlight religious influence on corporate philanthropic giving in contemporary China, an old traditional country with a typical communist economy. (shrink)

Using a sample of Chinese listed firms in polluting industries for the period of 2008–2010, we empirically investigate whether and how Buddhism, China’s most influential religion, affects corporate environmental responsibility (CER). In this study, we measure Buddhist variables as the number of Buddhist monasteries within a certain radius around Chinese listed firms’ registered addresses. In addition, we hand-collect corporate environmental disclosure scores based on the Global Reporting Initiative (GRI) sustainability reporting guidelines. Using hand-collected Buddhism data and corporate environmental disclosure scores, (...) we provide strong and robust evidence that Buddhism is significantly positively associated with CER. This finding is consistent with the following view: Buddhism can serve as social norms to evoke the consciousness of social responsibility, and thereof strengthen CER. Our findings also reveal that the positive association between Buddhism and CER is attenuated for firms with higher law enforcement index. The results are robust to various measures of Buddhism and a variety of sensitivity tests. (shrink)

Using multisource data and multilevel analysis, we propose that the ethical stance of supervisors influences subordinates’ perceptions of corporate social responsibility which in turn influences subordinates’ trust in the organization resulting in their taking increased personal social responsibility and engagement in organizational citizenship behaviors oriented toward both the organization and other individuals. Using a multilevel model, we assessed the extent to which ethical leadership and CSR at the work unit level impacts subordinates’ behaviors mediated by organizational trust at the individual (...) level. We employed a sample of 71 work unit supervisors and 308 subordinates from five businesses of a conglomerate company located in mainland China. Subordinates were asked to rate supervisory ethical leadership practices, CSR, and their extent of organizational trust. Supervisors were asked to rate the personal social responsibility taking and OCB of their respective subordinates. A multilevel path analysis revealed that ethical leadership has a positive effect on CSR at the work unit level and that CSR has a positive cross-level effect on organizational trust at the individual level, which in turn significantly and positively impacts OCB through the mediating effect of taking personal social responsibility. Results are discussed in the context of China’s manufacturing sector. (shrink)
