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.

In this paper we prove that any c. e. degree is splittable with an c. e. infimum over any lesser c. e. degree in the class of d-c. e. degrees.

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.

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.

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.

Conflicts between target and distraction can occur at the level of both stimulus and response processing. However, the neural oscillations underlying occurrence of the interference in different levels have not been understood well. Here, we reveal such a neural oscillation modulation by combining a 4:2 mapping design (two targets are mapped into one response key) with a practice paradigm (pretest, practice, and posttest) when healthy human participants were performing a novel color-word flanker task. Response time (RT) results revealed constant stimulus (...) conflict (SC, stimulus incongruent minus congruent, SI-CO) but increased response conflict (RC, response incongruent minus stimulus incongruent, RI-SI) with practice. Event-related potential (ERP) results demonstrated stable P3 amplitude differences for the SI-CO in the centro-parietal region across practice, which may reflect maintenance of the stimulus processing; and significantly larger P3 amplitudes in the same region for the RI relative to SI trial type in posttest, which may reflect inhibition of the distraction response. Further, neural oscillatory results showed that with practice, the lower alpha band in the frontal region and the upper alpha band in the occipital-parietal region distinguished between stimulus- and response-conflicts, respectively, suggesting that practice reduces the alertness (sensitiveness) of the brain to conflict occurrence, and enhances stimulus-response associations.

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.

Resumen: La cultura deportiva universitaria es un componente importante del sistema cultural nacional. Es la cristalización de la civilización material y espiritual en el deporte universitario, así como la precipitación de la cultura deportiva y la filosofía del deporte. Sin embargo, en la nueva era, la cultura deportiva universitaria presenta problemas como valorar más la inteligencia que la forma física, carecer de conceptos de cultura deportiva y separar el espíritu de lo material. En la educación universitaria, generalmente se presta más (...) atención al desarrollo académico e intelectual, mientras que no tanto al deporte y ejercicio físico. De hecho, la cultura deportiva universitaria a menudo se centra sólo en la educación física y los eventos deportivos, ignorando el desarrollo de otros aspectos, lo que da lugar a un desequilibrio en todo el sistema de cultura deportiva; la insuficiente inversión de la escuela en instalaciones y equipos deportivos conduce a una falta de apoyo material necesario para que los estudiantes lleven actividades de ejercicio físico. Al mismo tiempo, la comprensión y la búsqueda del deporte por parte de los estudiantes se quedan a menudo en la superficie, careciendo de la búsqueda del espíritu de lo profundo. En la revisión de la cultura deportiva universitaria, se puede utilizar el materialismo dialéctico para analizar la conexión entre el trasfondo social, la tendencia de desarrollo y la influencia mutua de la cultura deportiva; también se puede utilizar la perspectiva del constructivismo social para explorar el proceso de construcción social de la cultura deportiva, los papeles y las interacciones de todos los participantes, y el significado y la influencia de la cultura deportiva en la sociedad. Por consiguiente, para resolver mejor los problemas existentes en la cultura deportiva universitaria, promover el rápido desarrollo de la cultura deportiva universitaria en la nueva era, aumentar la confianza de la cultura deportiva universitaria y construir una cultura deportiva fuerte, este artículo utilizó el método del materialismo dialéctico para analizar la situación actual del deporte universitario. Explica la relación entre la filosofía y la cultura deportiva desde una perspectiva filosófica, así como los problemas actuales de la cultura deportiva. Utilizó el método del constructivismo social para explicarlo desde diferentes perspectivas. Por último, a través del método del constructivismo social, examinó la cultura deportiva universitaria en la nueva era y analizó dialécticamente las formas, funciones, vías de reconstrucción y pensamiento futuro de la cultura deportiva universitaria. La investigación ha constatado que la cultura deportiva de las universidades en la nueva era desempeña un papel importante en los aspectos cultural, educativo y político. La reconstrucción y el desarrollo futuro de la cultura deportiva universitaria en la nueva era necesitan combinar las culturas oriental y occidental, heredar la excelente cultura tradicional y lograr un desarrollo innovador de la cultura deportiva.

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)

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.

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.

Studying the psychology behind the purchase of eco-friendly products and second-hand items can offer valuable insights to promote sustainable consumer behavior. This paper examines factors influencing Italian consumers’ willingness to pay regarding bio-based clothing and second-hand items. Drawing from data collected from 402 Italian participants, we examine how motivations and socio-demographic factors are associated with willingness to pay in the context of sustainable fashion. Our findings reveal that motivations related to environmental concerns are positively associated with consumers’ willingness to pay (...) higher premiums for bio-based clothing. Higher income and education levels are also associated with the willingness to pay higher premiums. Meanwhile, motivation related to vintage appeal is associated with lower desired discounts for second-hand items, particularly among older consumers. Gender differences also influence discount preferences, with men seeking larger discounts on second-hand clothing compared to women. By providing insights into Italian consumers’ sustainable fashion choices, this study offers implications for businesses, policymakers, and researchers aiming to promote eco-conscious consumption and sustainability in the fashion industry.

I present a detailed ethnographic study of magic and divination of the Nuosu people in southwest China and offer a cognitive account of the surprising prevalence of these objectively ineffective practices in a society that has ample access to modern technology and mainstream Han culture. I argue that in the belief system of the Nuosu, ghosts, divination, and magical healing rituals form a closely interconnected web that gives sense and meaning to otherwise puzzling practices, and such a belief system is (...) importantly supported and reinforced by individual’s everyday experiences. Contemporary Nuosu people overwhelmingly treat these practices as instruments for achieving specific ends and often entertain considerable uncertainty regarding their efficacy, which may be overestimated for a number of reasons, including the following: (1) the intuitive plausibility of divination for ghost identification and exorcist rituals is enhanced by the belief in the existence of ghosts as a result of abductive reasoning, (2) negative instances (divinatory or healing ritual failures) are underreported, and (3) people’s misperception of the probability of uncertain events’ occurrence often prevents them from realizing that the efficacies of magical/divinatory practices do not outperform chance. I conclude with some comments on the generalizability of the psychological and social mechanisms discussed. (shrink)

The cultural rise of “big data” in the recent years has pressured a number of occupations to make an epistemological shift toward data-driven science. Though expressed as a professional move, this article argues that the push incorporates gendered assumptions that disadvantage women. Using the human resource occupation as an example, I demonstrate how normative perceptions of feminine “soft skills” are seen as irreconcilable with the masculine “hard numbers” of a data-driven epistemology. The history of human resources reflects how assumptions of (...) a biological fit with an occupation limit what women can convincingly describe as her skillsets. However, challenging this cannot stay within the confines of the occupation itself. To undo sexist thinking, it is necessary to understand the broader networks of patriarchal power that dictate how value is defined in corporate environments, especially within other high status professions in business.

Global citizenship education (GCE) encounters epistemic barriers in curriculum localisation, which, from a semiotic perspective, are related to educators’ subjectivation process. By choosing a Chinese case based on six secondary schools on the east coast of China, this paper builds on previous efforts to investigate how principals’ (n = 6) and teachers’ (n = 10) subjectivation process could influence their comprehension of the concept of GCE. The focus of this paper is on distinguishing the subjectivities in participants’ interviews that related (...) to their perceptions and planning of the curriculum. The findings of the study included qualitative feedback, which was later categorised into three themes: the communitarian subjectivity, the hybrid subjectivity and the assimilated subjectivity. The three forms of subjectivity exposed the vulnerability inherent in participants’ efforts to localize GCE. This study demonstrated a specific epistemic condition that challenges the prevailing discourse, suggesting that defending traditional culture does not always serve the purpose of promoting cultural diversity on a global scale.

In his praise for Part I of Upbuilding Discourses in Various Spirits, the eminent Kierkegaard scholar Eduard Geismar said, "I am of the opinion that nothing of what he has written is to such a degree before the face of God. Anyone who really wants to understand Kierkegaard does well to begin with it." These discourses, composed after Kierkegaard had initially intended to end his public writing career, constitute the first work of his "second authorship." Characterized by Kierkegaard as ethical-ironic, (...) Part One, "Purity of Heart Is to Will One Thing," offers a penetrating discussion of double-mindedness and ethical integrity. Part Two, "What We Learn from the Lilies in the Field and from the Birds of the Air," humorously exposes an inverted qualitative difference between the learner and the teacher. In Part Three, "The Gospel of Sufferings, Christian Discourses," the philosopher explores how joy can come out of suffering. (shrink)

In the 1880s, there had existed a series of controversies between the proponents of open and closed transformers. James Swinburne reopened it in 1889 when he designed a new type of open ‘Hedgehog’ transformer, and argued that it had the highest all-day efficiency. Three years later, John Ambrose Fleming showed that the Hedgehog was not the best but rather close to the worst. The bitter controversy between Swinburne and Fleming ended quickly, as Fleming made the unstable AC power measurement stable (...) by creating agreement concerning the calibration of AC instruments with the help of Kelvin's authority. Instruments, measurement, and calibration were intimately bound up with hegemonic issues in late-Victorian electrical engineering. (shrink)

The purpose of this study was to develop the OL-IAT, an IAT tool that measures implicit attitudes toward organizational loyalty, and to verify its predictive validity. In total, 15 respondents were randomly selected from among the employees of P Company. The respondents were then asked open questions about the image they held of the target company. Based on their responses, a list of words was compiled for use on the OL-IAT. Evaluation categories, either like-dislike or positive-negative, were developed for this (...) test based on the approach-avoidance words proposed by Ostafin and Palfai. The OL-IAT was then administered to 127 employees of Company P, and self-reporting measures were also devised to measure explicit attitudes. A survey of whether the implicit attitude toward organizational loyalty was consistent with the explicit attitude showed that there was no significant correlation, and the attitude inconsistency was evident in the responses. When differences in rank were accounted for, organizational loyalty attitudes were consistent at the manager level, and organizational participation attitudes were consistent at the manager and general staff levels. This study will aid in the development of effective measures of organizational loyalty and accelerate interventions to increase it, which in turn will positively impact long-term organizational growth.
