The Negative Problem Orientation Questionnaire is a widely used tool for assessing negative problem orientation. However, its construct and measurement invariance has not been adequately tested in adolescents. The present study explored the possible construct of the NPOQ and its measurement invariance in a sample of 754 Chinese adolescents. The results supported a bifactor model of the NPOQ that consists of a general factor NPO and three domain-specific factors including perceived threat, self-inefficacy, and negative outcome expectancy. A multiple-group CFA indicated (...) that the bifactor model showed strict invariance across gender and age. The general and domain factors showed unique variance in indexes of worry, depression, anxiety, and stress, which supported well incremental validity of them. This study confirms for a bifactor conceptualization of the NPOQ and its measurement invariance across gender and age in Chinese adolescents. Additionally, it is recommended that the total score should be used to assess NPO in Chinese adolescents. (shrink)

Yan Fu was the first Chinese person to introduce the teachings of the West to China systematically. Since returning to China from Britain, to which he had been sent to study in 1879, he held an office at the Beiyang Naval College until leaving the institution in 1900. These twenty-some years were precisely the direst moment in the intensifying of China's social crisis, when the imperialists were pressing their aggression toward China and China was being brought to the brink of (...) being partitioned outright. At the time, all the progressive intellectuals in China were worried for the future of the motherland, and pressed on to find what they considered to be the truth of national salvation. The bourgeois reformist faction of the day, with Kang Youwei as its leader, advocated political and legal reform and was tremendously enthusiatic and active in pleading its case throughout China, calling on the intellectuals to respond. Yan Fu, too, at this time, did a large amount of propaganda work for the cause of reform, using the thought of Lao Zi and Zhuang Zi as his foundation and employing his own exceptional knowledge of Western things and Western learning, and his understanding of the capitalist world. He founded the Guowen bao and published a number of important political essays, including "Lun shibian zhi ji" , "Yuan qiang" , "Pi Han" and "Jiu wang jue lun" . He also translated a number of the works of Western bourgeois social science, including [Thomas Huxley's] Evolution and Ethics , [Adam Smith's] The Wealth of Nations , [Herbert Spencer's] A Study of Sociology , [John Stuart Mill's] Logic , and Montesquieu's De l'esprit des lois . Furthermore, he carried out an annotated and evaluative reading of Lao Zi and Zhuang Zi, and in so doing he assimilated Western learning and ideas into the Chinese interpretation of Lao-Zhuang's thought.

On June 30, 1949, just before the nationwide victory of the Chinese Revolution, Mao Zedong wrote his On the People's Democratic Dictatorship, one section of which deals with the Chinese people's quest for revolutionary truth. He wrote that, from the time of China's Opium War in 1840, Chinese progressives such as Hong Xiuquan, Kang Youwei, Yan Fu, and Sun Yatsen went through untold hardships in their search for truth from the Western countries, but nothing worked.

First published in 1958. This volume translates one of the major works of modern Chinese philosophy and in so doing makes a major contribution to the study of comparative philosophy.

Machery et al. presented data suggesting the existence of cross-cultural variation in judgments about the reference of proper names. In this paper, we examine a previously overlooked confound in the subsequent studies that attempt to replicate the results of Machery et al. using East Asian languages. Machery et al. and Sytsma et al. claim that they have successfully replicated the original finding with probes written in Chinese and Japanese, respectively. These studies, however, crucially rely on uses of articleless, ‘bare noun (...) phrases’ in Chinese and Japanese, which according to the linguistic literature are known to be multiply ambiguous. We argue that it becomes questionable whether the extant studies using East Asian languages revealed genuine cross-cultural variation when the probes are reevaluated based on a proper linguistic understanding of Chinese and Japanese bare noun phrases and English definite descriptions. We also present two experiments on native Japanese speakers that controlled the use of ambiguous bare noun phrases, the results of which suggest that the judgments of Japanese speakers concerning the reference of proper names may not diverge from those of English speakers.

In light of Laura Sizer's and Robert Thayer's models of mood, I propose a functional theory to explain in what sense moods are adaptive. I argue that mood involves a mechanism which monitors our physical and mental energy levels in relation to the perceived energy demands of our environment, and generates corresponding cognitive biases in our reasoning style, attention, memory, thought, and creativity. The function of this mechanism is to engage us in the right task with the right amount of (...) energy by maintaining equilibrium between the energy we possess and the energy our environment demands.

Previous studies have shown that the color red can affect basic motor functioning. However, these studies utilized simple gross motor tasks rather than those assessing complex fine motor skills. Moreover, these empirical studies were theoretically based on the threat–behavior link in human and non-human animals, and neglected the relationship between arousal and motor performance. According to the Yerkes–Dodson law and the inverted-U hypothesis in sport psychology, for simple motor tasks, high arousal is more advantageous than low arousal ; for complex (...) motor tasks, low arousal is more advantageous than high arousal. The current research examined the effect of color on different kinds of motor skills based on the inverted U-hypothesis. In Experiment 1, we examined the effect of red and blue on dart-throwing performance, whereas in Experiment 2, we examined the effect of red and blue on grip strength performance. The results showed that performance of fine motor skill in the blue condition was better than in the red condition, and performance of gross motor skill in the red context was better than in the blue context. These results indicate that the type of motor skill assessed moderates the influence of red and blue on motor performance. (shrink)

BackgroundChildhood experiences can exert a huge impact on adult psychological conditions. Previous studies have confirmed the effects of adverse childhood experiences and benevolent childhood experiences on psychological distress separately, but few studies explored a combined effect of ACEs and BCEs on psychological distress. The aim of this study was to explore a combined effect of ACEs and BCEs on psychological distress among Chinese undergraduates.MethodsParticipants were undergraduates aged 17–24 years and completed a self-reported questionnaire. A series of regression analyses were conducted (...) to examine the association between childhood experiences and psychological distress.ResultsA total of 65.7% of undergraduates had BCEs, 27.1% of undergraduates had ACEs, and 12.9% of undergraduates had ACEs and BCEs simultaneously. Logistic regression analysis indicated that undergraduates who experienced high ACEs were more likely to have a high risk of psychological distress [odds ratio = 1.46, 1.84, and 3.15 for uncertainty stress, depressive symptoms, and suicidal ideation, respectively], while undergraduates who experienced High BCEs were less likely to have psychological distress compared with Low-Both group. The combined effect of ACEs and BCEs could also play as a protective factor in uncertainty stress and depressive symptoms.ConclusionOur findings suggested that ACEs and BCEs could not only predict the psychological distress independently, but also BCEs could counteract the negative effect of ACEs in psychological problems. There is an even greater need to identify and support the victims of ACEs and to increase BCEs in early childhood. (shrink)

Guanxi, or social networks common in Confucian cultures, has long been recognized as one of the major factors for success when doing business in China. However, insider networks in business are certainly not confined to Asian cultures, nor is the attendant possibility for corruption. This study obtained original data to investigate current Taiwanese perceptions of (1) how guanxi is established and cultivated; (2) how guanxi actually is practiced now and people’s acceptance of it; and (3) the effects of guanxi on (...) business operations, employment/promotion, and social justice and fairness. The researchers also hope to (4) verify some arguments made by pioneering researchers. The authors speculate on how these attitudes may affect behavior in business transactions in hopes of making readers more aware of differing cultural values that may create unexpected ethical dilemmas. They suggest that professional ethical codes should provide guidance on the practice of guanxi in a Confucian society and that special emphasis or training in interpreting those codes may be required.

Recent research has linked the reduction of abnormal accruals to corporate governance metrics. The results of these studies, however, are based on samples taken from periods prior to promulgated board independence requirements. In other words, during this time period, management not only had discretion over accounting accruals, but also significant influence over the choice of membership on the board of directors. This study suggests that ethical management practices may be a correlated omitted variable in these studies, thus resulting in causal (...) inference problems in the previous research. We argue that, rather than the board of directors monitoring and reducing abnormal accruals as has been posited, management who was not engaging in abusive earnings management was attempting to signal the market regarding the quality of the firm’s financial information through its choice of board membership.

A self-designed questionnaire was given to 634 health professionals in a large teaching hospital in Hubei Province in mainland China, to clarify the participants’ attitude towards information disclosure to cancer patients. Statistic description was used to analyze the data. The item ‘inappropriate information about cancer easily leads to medical disputes’ scored highest at 3.86, while the scores of such items as ‘advantages of fully informing patients outweigh disadvantages’, ‘if their family members demand nondisclosure, you will find it difficult to cooperate (...) in good faith with patients’, and ‘telling white lies to patients disturbs you a lot’ were less than 3. The health care staff placed a high value on both the desire and priority of patients to know the truth, though most of them did not think that patients had received enough information about their disease. In order to improve cancer patients’ current state of knowledge, health professionals should learn more about informed consent, and special methods and guidelines compatible with Chinese culture are urgently required in China.

As more organizations adopt telecommuting or working from home, the work-connected behavior of their employees during non-working hours increases, weakening the boundary between work and family. However, no study has clearly identified whether and how work connectivity behavior after-hours affects employees’ work and family status. Therefore, using role theory, we explored the mechanisms by which WCBA affects employees’ thriving at work and family through work–family enrichment and work–family conflict, and compared the impact of different levels of support for family members (...) on work–family enrichment and conflict, using the Johnson–Neyman method. Our analysis of two-wave data from 257 employees led to the following findings. WCBA had a positive impact on thriving at work, but not on family. There is a ‘double-edged sword’ effect on the impact of WCBA on thriving at work, meaning that work–family enrichment can positively influence thriving at work and negatively influence work–family conflict. There is a double-edged sword effect on the impact of WCBA on thriving at family, meaning that work–family enrichment can positively influence thriving at family and negatively influence work–family conflict. The support of family members moderates the double-edged sword effect between WCBA and thriving at work, in that it can strengthen the positive effects of work–family enrichment and weaken the negative effects of work–family conflicts. Support from family members reinforces the positive impact of work–family enrichment on thriving at family. Thus our study reveals the mechanisms by which WCBA affects the thriving at work and family of employees, and identifies potential methods for managing different levels of work–family enrichment and work–family conflict from the perspective of family member support.

Mutation and lateral transfer are two categories of processes generating genetic diversity in prokaryotic genomes. Their relative importance varies between lineages, yet both are complementary rather than independent, separable evolutionary forces. The replication process inevitably merges together their effects on the genome. We develop the concept of “open lineages” to characterize evolutionary lineages that over time accumulate more changes in their genomes by lateral transfer than by mutation. They contrast with “closed lineages,” in which most of the changes are caused (...) by mutation. Open and closed lineages are interspersed along the branches of any tree of prokaryotes. This patchy distribution conflicts with the basic assumptions of traditional phylogenetic approaches. As a result, a tree representation including both open and closed lineages is a misrepresentation. The evolution of all prokaryotic lineages cannot be studied under a single model unless new phylogenetic approaches that are more pluralistic about lineage evolution are designed. (shrink)

The predictors of attitudes regarding academic plagiarism were investigated in Hong Kong secondary school students. The participants were 257 Grade 10 and 11 students who were taking liberal studies. Quantitative analysis showed that the students were unfamiliar with what actions constituted plagiarism. The best predictor of attitudes was the perceived descriptive norm regarding plagiarism. We explain this finding by applying the cultural-self perspective and present our recommendations for teachers.

Mental health issues are becoming increasingly prevalent amongst university students. However, research on the psychological profile of the general university population is relatively limited. Thus, this study analyses the current state of university students’ psychological conditions; the demographic differences in depression, anxiety, and stress and the influencing factors. The objectives are to provide additional appropriate guidance in mental health for university students with different demographic characteristics. A cross-sectional study of 6,032 university students nationwide was conducted from October 2020 to January (...) 2021. A randomized whole-group sampling method was used to select the study participants, and the 21-item Depression, Anxiety, and Stress Scale was used. P < 0.05 in the final model were considered statistically significant. The number of university students with no complain of depression, anxiety, or stress was 3,751. The odds of developing complain of depression were higher amongst anxious respondents and senior year than their counterparts. Students with “myopia” were 1.263 times more likely to be anxious. In terms of “impaired” or not, impaired is defined as any injury, such as sprain, strain, and fracture, “impaired” university students were 1.321 times more likely to be anxious. Furthermore, history of impairment and myopia increased the odds of stress by 1.305 and 1.305, respectively. Myopia, physical-activity-related injury and irrational eating habits are risk factors for complain of anxiety and stress. Males, upper grades, low parental education, and irrational eating habits are risk factors for complain of depression. Low physical activity levels are also an influential factor for complain of depression. DASS consists of interchangeable risk factors and multiple complains of DASS may coexist. (shrink)

Background Caring behaviour is critical for nursing quality, and the clinical internship environment is a crucial setting for preparing nursing students for caring behaviours. Evidence about how to develop nursing students’ caring behaviour in the clinical environment is still emerging. However, the mechanism between the clinical internship environment and caring behaviour remains unclear, especially the mediating role of moral sensitivity and the moderating effect of self-efficacy. Research objective This study aimed to examine the mediating effect of moral sensitivity and the (...) moderating function of self-efficacy on the association between the clinical internship environment and caring behaviours. Research design A cross-sectional design used acceptable validity scales. The hypothesised moderated mediation model was tested in the SPSS PROCESS macro. Participants and research context This survey collected data from 504 nursing students in an internship at a teaching hospital in Changsha, China. Ethical considerations This study was pre-approved by the ethics committee of the medical school (No. E2022210). Informed consent was obtained from all students. Results The clinical internship environment ( B = 0.450, 95% CI = [0.371, 0.530]) and moral sensitivity ( B = 1.352, 95% CI = [1.090, 1.615]) had positive direct effects on nursing students' caring behaviours. Clinical internship environment also indirectly influenced students’ caring behaviours via moral sensitivity ( B = 0.161, 95% CI = [0.115, 0.206]). In addition, self-efficacy played a moderating role between the clinical internship environment and caring behaviours ( B = 0.019, 95% CI = [0.007, 0.031]), as well as the relationship between the clinical internship environment and moral sensitivity ( B = 0.006, 95% CI = [0.003, 0.010]). Conclusion Moral sensitivity mediates the effect of the clinical internship environment on caring behaviour, and self-efficacy strengthens both direct and indirect effects. This study emphasises the importance of self-efficacy in developing moral sensitivity and caring behaviours in nursing students. (shrink)

None of the studies published in the extant literature has discussed the role of green innovation climate and green autonomy concerning green creativity and this study aims to offer these two novel constructs. By introducing the componential theory of creativity, this study explores green transformational leadership, green innovation climate, and green autonomy as antecedents of green creativity. The authors employed structural equation modeling to analyze survey-based data collected from automotive firms in China. Data were collected from employee-supervisor working in the (...) automotive industry located in Liaoning province, China. The findings reveal that GTL directly and indirectly via green innovation climate partially mediates the green creativity of employees in China. Moreover, green autonomy moderates the relationship between green innovation climate and green creativity. This pivotal contribution suggests that automotive business enterprises should develop GTL to nurture a green innovation climate and offer green autonomy for the green creativity of employees. The above antecedents of green creativity may enable business firms to gain a competitive advantage by innovating green products and practices. (shrink)

Despite globalization and the rapid development of information technology, cross-cultural dialogue did not become any easier. The physical and non-physical confrontations are intensified by the differences in basic values and interest of cultures, which can be seen by the increasing number of wars, extreme localism, and mistrust between people. Rationality, which has long been regarded as the best and the only common language among different cultures, fails to facilitate communication and collaboration. Rationality’s limitation was revealed among others in Alasdair MacIntyre’s (...) Whose Justice? Which Rationality? Unlike what ancient Greek philosophers suggested, there is not a single type of supreme rationality that everyone will and should follow. The only consensus perhaps is about the instrumental rationality suggested by Max Weber, which is futile in promoting cross-cultural dialogues as it addresses the various means rather than the ends of different cultures. In this paper, I argue that emotion is a better language for universal dialogue than rationality in two senses. First, the psychologists and anthropologists provide solid evidence to prove that certain emotions are basic and universal among all human beings. For instance, based on his study of facial expression of the Fore people in Papua New Guinea, Ekman proposed that anger, fear, surprise, disgust, sadness, and happiness are six basic emotions that are universally shared. Other evidence includes studies conducted by Tomkins, Arnold, and Frijda. These basic emotions might serve as the foundation of cross-cultural dialogue because we are evolved to understand the causes and expressions of these emotions in others despite the cultural and social differences. Second, unlike instrumental rationality that focuses solely on how to achieve one’s end, certain emotions are non-egocentric by nature. For instance, compassion is “another-oriented emotion elicited by and congruent with the perceived welfare of another person”. Chinese philosophy expresses a similar idea with the aid of the concept of Ren, which is the essence of human being, according to Confucianism. Love is another non-egocentric emotion that is constituted by care and concern of the well-being of one’s beloved for his or her own sake. That is, I love you not because loving you makes me happy, instead, it is because loving you makes you happy. Such non-egocentric emotions might encourage and motivate crosscultural dialogue despite the conflict of interest between cultures. While facing multifaceted contemporary problems and crisis, we do not lack rational and intelligent solutions. We lack mutual understanding, reciprocal tolerance, and sustainable collaboration. The role of emotion in establishing a platform of cross-cultural dialogue should not be overlooked. (shrink)

In nature, gregarious animals, insects, or bacteria usually exhibit paradoxical behaviors in the form of group fission and fusion, which exerts an important influence on group’s pattern formation, information transfer, and epidemiology. However, the fission-fusion dynamics have received little attention compared to other flocking behavior. In this paper, an intermittent selective interaction based control algorithm for the self-organized fission-fusion behavior of flocking system is proposed, which bridges the gap between the two conflicting behaviors in a unified fashion. Specifically, a hybrid (...) velocity coordination strategy that includes both the egalitarian and selective interactions is proposed, where the egalitarian interaction is to maintain the flock’s order and achieve the fusion behavior while the selective interaction strategy is for the response to external stimulus information and generates the fission behavior. Numerical simulations demonstrate that the proposed control algorithm can realize the self-organized fission-fusion behavior of flocking system under a unified framework. The influences of the main control parameters on the performance of the fission-fusion behavior are also discussed. In particular, the trade-off parameterαbalances the exploration and exploitation behaviors of flocking system and significantly enhances its movement flexibility and environmental adaptivity.

Acute stress is believed to lead to prosocial behaviors via a “tend-and-befriend” pattern of stress response. However, the results of the effect of acute stress on prosocial behavior are inconsistent. The current study explores the moderating effect of gender and social value orientation on the relationship between acute stress and individuals’ pure prosocial behaviors. Specifically, eighty-one participants were selected and underwent the Trier Social Stress Test, followed by the third-party punishment task and the dictator game. The results showed that, in (...) general, the main effect of condition or respiratory sinus arrhythmia reactivity on individual prosocial behaviors was significant and did not vary between genders. Furthermore, social value orientation might moderate the impact of RSA reactivity on the amount of punishment in the third-party punishment task. That is, individuals with self-orientation exhibited more prosocial third-party punishment as RSA reactivity decreased, while the effect did not occur for individuals with prosocial orientation. Taken together, the findings of the current study provide further evidence for the “tend-and-befriend” hypothesis and highlight the underlying physical mechanisms as well as the individual dependence of the effect of psychosocial stress on individuals’ pure prosocial behaviors.

Although current literature demonstrates how parents benefit from parent empowerment programs, the development of a quantitative measure of parent empowerment has garnered limited attention in parenting research. The goal of this research was therefore to develop and validate a quantitative measure for the assessment of practitioners’ attitudes and competence in parent empowerment. In the process of item generation, the qualitative findings derived from four studies in relation to the perceived outcomes and experiences in parent empowerment were synthesized in the first (...) stage. In the second stage, a list of narratives that articulated different themes of parent empowerment was generated, which resulted in an item pool containing 28 items. In the third stage, the research team converted the 28 items into a survey instrument. In the fourth stage, a first-scale validation study was conducted to explore the factor structure of the initial 28-item questionnaire. The exploratory factor analysis on the first sample of 366 practitioners yielded a twofold factor structure with 17 items, including practitioners’ attitudes in parent empowerment and practitioners’ competence in parent empowerment. In the final stage, a second-scale validation study was undertaken to verify the fit of the twofold factor structure. A confirmatory factor analysis on the second sample of 170 practitioners demonstrated a good model fit. The results of reliability tests for the whole scale and two subscales also indicate satisfactory internal consistency. The Parent EmpowermentviaTransformative Learning Questionnaire (PETLQ) was thus developed and confirmed as a scale with sufficient factorial validity and internal consistency to be used for assessing parenting practitioners’ attitudes and competence in parent empowerment and for evaluating the effectiveness of parent empowerment programs.

Public education finance in China plays an important role in education equality. This study investigated two mediation effects with a generalized structural equation model that comprised the mediation effect of shadow education at the school, family, and individual levels and the moderating role of education finance. There was a strong association among heterogeneity factors, shadow education, and educational results, with shadow education playing a mediating role in math and English courses. Individual heterogeneity differences had a negative impact on equality in (...) educational results through access to additional shadow education opportunities, while heterogeneous factors were mediated through shadow education, causing financial moderation effects, in turn affecting inequality in educational results. Finally, the moderation degree and direction of education finance varied significantly, with a greater moderation effect on household-level factors that lead to unequal educational results. Targeted efforts are required to regulate shadow education, which is key to the development of the education system. (shrink)

Physarum polycephalum, a unicellular and multiheaded slime mould, can form highly efficient networks connecting separated food sources during the process of foraging. These adaptive networks exhibit a unique characteristic in that they are optimized without the control of a central consciousness. Inspired by this phenomenon, we present an efficient exploration and navigation strategy for a swarm of robots, which exploits cooperation and self-organisation to overcome the limited abilities of the individual robots. The task faced by the robots consists in the (...) exploration of an unknown environment in order to find a path between two distant target areas. For the proposed algorithm, we experimentally present robustness tests and obstacle tests conducted to analyse the performance of our algorithm and compare the proposed algorithm with other swarm robot foraging algorithms that also focus on the path formation task. This work has certain significance for the research of swarm robots and Physarum polycephalum. For the research of swarm robotics, our algorithm not only can lead multirobot as a whole to overcome the limitations of very simple individual agents but also can offer better performance in terms of search efficiency and success rate. For the research of Physarum polycephalum, this work is the first one combining swarm robots and Physarum polycephalum.
