The target article presented a plausible argument that females' susceptibility to threats might be self-protection for staying alive, but some evidence requires scrutiny. We need to consider the biases of narrative reviews, subjective life quality, and the shadow side of extreme reactions to threats before concluding that females' threat-based response is a self-protection mechanism that promotes survival.

To explore whether the generation of new protein folds could be linked to metallic cofactor recruitment, we identified the oldest examples of folds for manganese, iron, zinc, and copper proteins by analyzing their fold‐domain mapping patterns. We discovered that the generation of these folds was tightly coupled to corresponding metals. We found that the emerging order for these folds, i.e., manganese and iron protein folds appeared earlier than zinc and copper counterparts, coincides with the putative bioavailability of the corresponding metals (...) in the ancient anoxic ocean. Therefore, we conclude that metallic cofactors, like organic cofactors, play an evolutionary role in the formation of new protein folds. This link could be explained by the emergence of protein structures with novel folds that could fulfill the new protein functions introduced by the metallic cofactors. These findings not only have important implications for understanding the evolutionary mechanisms of protein architectures, but also provide a further interpretation for the evolutionary story of superoxide dismutases.

Protein redox reactions are one of the most basic and important biochemical actions. As amino acids are weak redox mediators, most protein redox functions are undertaken by protein cofactors, which include organic ligands and transition metal ions. Since both kinds of redox cofactors were available in the pre‐protein RNA world, it is challenging to explore which one was more involved in redox processes of primitive proteins? In this paper, using an examination of the redox cofactor usage of putative ancient proteins, (...) we infer that organic ligands participated more frequently than transition metals in redox reactions of primitive proteins, at least as protein cofactors. This is further supported by the relative abundance of amino acids in the primordial world. Supplementary material for this article can be found on the BioEssays website.

Speech recognition technology has played an indispensable role in realizing human-computer intelligent interaction. However, most of the current Chinese speech recognition systems are provided online or offline models with low accuracy and poor performance. To improve the performance of offline Chinese speech recognition, we propose a hybrid acoustic model of deep convolutional neural network, long short-term memory, and deep neural network. This model utilizes DCNN to reduce frequency variation and adds a batch normalization layer after its convolutional layer to ensure (...) the stability of data distribution, and then use LSTM to effectively solve the gradient vanishing problem. Finally, the fully connected structure of DNN is utilized to efficiently map the input features into a separable space, which is helpful for data classification. Therefore, leveraging the strengths of DCNN, LSTM, and DNN by combining them into a unified architecture can effectively improve speech recognition performance. Our model was tested on the open Chinese speech database THCHS-30 released by the Center for Speech and Language Technology of Tsinghua University, and it was concluded that the DLD model with 3 layers of LSTM and 3 layers of DNN had the best performance, reaching 13.49% of words error rate.

Prior research finds that firms with strong business ethics are less likely to be tax aggressive. Labor union is one of the key stakeholders influencing firm’s tax aggressive behavior, whereas the bargaining process between labor union and firms exhibits ethical dilemma. Although industry-wide labor union coverage is commonly used in prior study to explore the monitoring role of labor unions in constraining management’s aggressive financial and tax decisions of their associated firms, we argue that firm-specific labor unions, which represent a (...) different bargaining power of the employees, do play an important role in determining firms’ tax ethical decisions. Specifically, we examine whether and how the firm-specific labor union coverage impacts firms’ tax aggressiveness decisions over and above industry-wide labor union coverage. We hypothesize and find that firm-specific labor unions influence the associated firms to be more tax aggressive, which results in higher levels of residual cash flows. We also find that industry-wide labor unions influence the associated firms to be less tax aggressive, which is consistent with prior findings. We perform further analyses and find that the results are more pronounced for the firms with greater industry-wide labor unions representation. These results demonstrate that the inclusion of and interaction between the firm-specific and industry-wide labor unions matter in determining corporate’s tax aggressiveness decisions, which highlight firm’s ethical perplexity between tax savings and social commitments.

The classical literature on Confucianism exhorted leaders to practice five core virtues as the basis for becoming a noble person and for sustaining harmonious communities built on trust and good example. We present a theory about how the senior management in modern corporations, by enacting the five Junzi virtues through virtuous environmental, social, and governance policies and practices, might inspire virtue-based relationships between superiors and subordinates and between employees. We argue that if middle managers and employees observe and experience that (...) their firm’s ESG policies and practices are virtuous, they would feel encouraged to practice those virtues in their own behavior, and thus embody and promote interpersonal harmony. We provide three types of illustration for our theory. First, we map the five Junzi virtues to the content of a specimen ESG report. Second, we map seven subtypes of servant leadership behavior of middle managers to the five Junzi virtues. Third, we map seven types of employee organizational citizenship behavior to the five Junzi virtues. (shrink)

A Higher education system is closely related to a country’s development. Governments need to make appropriate adjustments to ensure the healthy and sustainable development of higher education. To measure and evaluate the development status of the national higher education system and propose a set of policies, the following work has been done in this paper: First, this paper establishes a comprehensive evaluation index system based on the AHP-FCE model. The healthy development of education in significant countries was compared horizontally and (...) vertically. The results of weighted scores were used to determine the Japanese higher education system as the research object. Secondly, this paper uses factor analysis and principal component analysis to evaluate the level of sustainable development of higher education, detecting development barriers that migrate from the current to the future. This paper proposes a healthy and sustainable development policy blueprint from four aspects. Finally, this article uses the ARMA time series model to predict the development trend of Japanese higher education in the next 30 years and formulates a timetable for corresponding implementation arrangements. In addition, this paper quantitatively evaluates the effectiveness of the policies we propose and their impact on reality and provides references for other countries in the world. (shrink)

ObjectiveThe study aimed to enhance the learning motivation of college physical education students and improve their learning outcomes. Based on the perspective of the self-determination theory, this study explores the influence of “Small Private Online Course + flipped classroom” teaching on the learning motivation of students majoring in physical education and profoundly analyzes the influencing factors and promotion paths of learning motivation using this model.Materials and methodsA total of four classes of physical education majors in a university were selected and (...) randomly divided into an experimental group and a control group. The experimental group received “SPOC + flipped classroom” teaching, the control group received traditional teaching. Before and after the 16-week intervention, learning motivation, teacher support perception, basic psychological need satisfaction, and academic emotions of the 64 students were measured, and the data were analyzed by repeated-measures analysis of variance and partial least square regression.Results The instructional intervention reduced non-regulation, external regulation, and introjected regulation, while increased identified regulation, intrinsic regulation, and self-determination levels in the students. The levels of non-regulation, external regulation, identified regulation, and self-determination were also significantly different from those of the control group. After the intervention, the scores of support for autonomy, support for competence, support for relatedness, and need for relatedness in the experimental group were significantly higher than those in the control group. Support for autonomy, support for competence, support for relatedness, need for competence and need for relatedness positively predicted the self-determination level, and intrinsic regulation and identified regulation negatively predicted non-regulation, external regulation, and introjected regulation.Conclusion“SPOC + flipped classroom” teaching has a positive impact on students’ learning motivation of basketball skills and promotes students’ motivation autonomy. The improvement of support for autonomy, support for competence, support for relatedness, need for competence, and need for relatedness may be related to the improvement of learning motivation of college students majoring in Physical Education. “SPOC + flipped classroom” teaching enables students to obtain more demand satisfaction by giving them more demand support, while demand support and demand satisfaction can promote the internalization of learning motivation so that students can maintain high autonomy motivation.

Objective: Work stress is one of the urgent public health problems, which has aroused wide attention. In addition, work stress also has a negative impact on the development of enterprises. This study has three purposes: to understand the current status of working stress among couriers, to examine the association between work stress, job satisfaction and sleep quality of Chinese couriers, and to verify the mediating role of psychological capital.Methods: A cross-sectional survey was conducted among 3000 couriers in Beijing of China (...) from January to December 2019 using cluster stratified random sampling. Descriptive statistical analysis was used to describe demographic characteristics of respondents. Pearson correlation analysis was used to analyze the correlation among work stress, job satisfaction, sleep quality, and psychological capital. The mediating analysis was calculated role of psychological capital.Results: A total of 2831 participants were included in this study. The average score of work stress was 2.49 ± 0.76. Work stress was negatively correlated with job satisfaction, sleep quality, and psychological capital, respectively. The direct effect of work stress on job satisfaction is –0.223, and the total effect of work stress on job satisfaction is –0.267. The a*b*c’ is positive, indicating the mediating role psychological capital has in explaining the relationship between couriers’ work stress and job satisfaction. Moreover, psychological capital plays a mediating role between work stress and sleep quality among couriers.Conclusion: Couriers face certain work stress and should be paid attention to and psychological capital can effectively alleviate the work stress of couriers, so measures can be taken to improve it, promoting healthy development of employees and organizations.

A quite popular approach to solving the Causal Exclusion Problem is to adopt a counterfactual theory of causation. In this paper, I distinguish three versions of the Causal Exclusion Argument. I argue that the counterfactualist approach can block the first two exclusion arguments, because the Causal Inheritance Principle and the Upward Causation Principle upon which the two arguments are based respectively are problematic from the perspective of the counterfactual account of causation. However, I attempt to show that the counterfactualist approach (...) is unable to refute a sophisticated version (i.e. the third version) of the exclusion argument in that the Downward Causation Principle, a premise of the third exclusion argument, is actually implied by the counterfactual theory of causation. Therefore, even if other theories of causation might help the non-reductive physicalist to solve the exclusion problem, the counterfactual theory of causation cannot. (shrink)

This paper focuses on learning that takes place outside formal classrooms within groups or teams. Based on the conceptual framework of informal learning, adult learning and lifelong learning, it investigates how two contrasting groups of adult learners in Vietnam, Mekong doctors and Hanoi hairdressers, learn, interact, and collaborate through their informal learning experiences in the workplace. These are two ‘co-present groups’ or two ‘complex systems’. For Vietnamese learners, the challenges of Confucian heritage culture, or the lack of awareness of cultural (...) differences, created obstacles to collaboration and participation. The contribution to this Special Issue argues that co-present group learning applies well to non-Western Confucius-based cultures and other countries with similar values, despite this lack of awareness of cultural differences.
