This qualitative study presents 27 students’ insights about four teachers’ implementation of an immersive Native American history curricular unit designed to equip students with digital skills to critically navigate complex, polarizing social issues. The Digital Civic Learning (DCL) curriculum used Google Suite and Google Classroom or Schoology to provide collaborative slides supporting immersive 2D-graphics, children’s books/resources, immersive activities/artefact-creation, and multimodal tools (e.g., discussion posts, Flipgrid video-essays). Teachers regulated student thinking/behavior towards cohesive outcomes, and encouraged open-ended exploration, operationalizing the design framework (...) as a zone of proximal development (ZPD). The history unit incorporates four cybernetic design features (DF) that enable teachers to steer student-centered collaboration within the curricular unit. The teacher serves four diverse roles (guide, facilitator, modeler, participant observer) mapping onto the DF. Results of focus group interviews with students, which were analyzed based on a theory-informed coding scheme and narrative inquiry, suggest ways for social studies teachers to operationalize the DCL immersive history unit as a cybernetic ZPD by adapting its basic structure to technologies accessible in their schools by adapting its basic structure to technologies accessible in their schools.

The aim of this study was to compare the learning effectiveness of peer tutored problem-based learning and conventional teaching of nursing ethics in Taiwan. The study adopted an experimental design. The peer tutored problem-based learning method was applied to an experimental group and the conventional teaching method to a control group. The study sample consisted of 142 senior nursing students who were randomly assigned to the two groups. All the students were tested for their nursing ethical discrimination ability both before (...) and after the educational intervention. A learning satisfaction survey was also administered to both groups at the end of each course. After the intervention, both groups showed a significant increase in ethical discrimination ability. There was a statistically significant difference between the ethical discrimination scores of the two groups (P < 0.05), with the experimental group on average scoring higher than the control group. There were significant differences in satisfaction with self-motivated learning and critical thinking between the groups. Peer tutored problem-based learning and lecture-type conventional teaching were both effective for nursing ethics education, but problem-based learning was shown to be more effective. Peer tutored problem-based learning has the potential to enhance the efficacy of teaching nursing ethics in situations in which there are personnel and resource constraints. (shrink)

Faced with tremendous employment pressure, how to enhance effective career exploration and career adaptability is crucial for college students’ career. This study uses self-assessed data from 840 undergraduate students at three time points to reveal the formation mechanism of career adaptability from a dual perspective of teacher support and students’ effective part-time behavior. In particular, the mediating role of career exploration is introduced based on self-regulation theory, and the moderating role of teacher support and students’ effective part-time work is introduced (...) based on social cognitive career theory. The results show that Future work self-salience positively influences career adaptability; future work self-salience indirectly influences career adaptability through career exploration; both teacher support and students’ effective part-time behavior positively moderate the indirect relationship between future work self-salience and career adaptability through career exploration. This study attempts to provide practical guidance for college graduates to engage in career exploration and career construction. (shrink)

We investigate how firms adjust corporate pension plans in response to economic policy uncertainty (EPU). Using a sample of US-listed firms, we find that firms increase pension underfunding levels when facing higher EPU. The result is robust to controlling for pension portfolio returns, discount rates, plan sizes, pension liability, numbers of employees, other macroeconomic factors, difference-in-differences and instrumental variable estimation, and additional evidence of pension risk-shifting. Further analysis reveals that financial distress and information asymmetry induced through EPU are the potential (...) channels. The effect is stronger for firms having CEOs being excessively paid, using cash flow as a performance metric in CEO compensation, paying high dividends, and having short-term institutional investors, whereas the presence of unions, positive corporate culture, and social capital alleviate the effect. Notably, managers, not shareholders, appear to be the party reaping the benefits. Our findings suggest that firms may shift risk to employees in response to heightened uncertainty and institutional characteristics play a moderating role in this crucial business ethics issue.

This study attempts to investigate the relationships among the ethical beliefs of Chinese consumers and orientations based on attitudinal attributes: materialism and moral philosophies (idealism and relativism). In addition, this study examines Chinese consumers' ethical beliefs in relation to five selected demographic characteristics (gender, age, religion, family income and education). Based on this exploratory study of 284 Chinese consumers, the following statistically significant findings were discovered. First, Chinese consumers regard that a passively benefiting activity is more ethical, but actively benefiting (...) from an illegal or a questionable activity is unacceptable. Second, the two dimensions of passively benefiting and no harm/no foul can be used to distinguish the consumers who endorse higher levels of idealism or relativism. Third, Chinese consumers with a high level of materialism are more likely to actively benefit from illegal and questionable activities, and the passively benefiting actions. Finally, the more ethical Chinese consumers seem to be younger, be religious, and have a lower family income. (shrink)

The reversible phosphorylation of proteins on serine/threonine residues preceding proline (Ser/Thr‐Pro) is a major regulatory mechanism for the control of a series of cell cycle events. Although phosphorylation is thought to regulate protein function by inducing conformational changes, little is known about most of these conformational changes and their significance. Recent studies indicate that the conformation and function of a subset of these phosphorylated proteins are controlled by the prolyl isomerase Pin1 through isomerization of specific phosphorylated Ser/Thr‐Pro bonds. Furthermore, compelling (...) evidence supports the idea that proline‐directed phosphorylation and subsequent isomerization play a critical role not only in cell cycle control, but also in the development of Alzheimer's disease, where postmitotic neurons display various cell cycle markers, especially mitotic events, prior to degeneration.

Multiple accounts of how theories of human psychology and of image-making influenced each other in a decisive period in the history of philosophy and art.

This meta-analysis examines the relationship between materialism and subjective wellbeing in the Chinese population. Fifty-six relevant studies covering the period from 1998 to 2022 were included in the meta-analysis. Fifty-eight independent effect sizes from a total of 52,368 participants were obtained to calculate the mean effect sizes. Materialistic values correlated with significantly lower subjective wellbeing, while the mean effect size for extrinsic aspirations was found to be not significant. The effect sizes varied across different types of wellbeing outcomes. The associations (...) were also moderated by certain demographic factors, methodological factors, publication features, and economic indicators. We discuss our limitations and the implications for future research. (shrink)

A key property of relational representations is their generativity: From partial descriptions of relations between entities, additional inferences can be drawn about other entities. A major theoretical challenge is to demonstrate how the capacity to make generative inferences could arise as a result of learning relations from non-relational inputs. In the present paper, we show that a bottom-up model of relation learning, initially developed to discriminate between positive and negative examples of comparative relations, can be extended to make generative inferences. (...) The model is able to make quasi-deductive transitive inferences and to qualitatively account for human responses to generative questions such as “What is an animal that is smaller than a dog?” These results provide evidence that relational models based on bottom-up learning mechanisms are capable of supporting generative inferences.

The present study addresses language ostracism in intercultural communication, a phenomenon when someone speaks a language but some members of this language community don’t speak to him in this language. This phenomenon is illustrated by language behaviour towards visually distinct bilingual minorities in Taiwan. Visually distinct minorities in Taiwan reported that they had been spoken to in English by small children or people who did not believe and accept that they really understood Mandarin when they spoke it. They might be (...) spoken to in English despite actually speaking good Mandarin. Taiwanese people behave this way because of two conditions existing in Taiwan: an English-speaking foreigner stereotype where people assume that every foreign-looking person speaks English, and English privilege in Taiwanese society which leads to people being treated better if they can speak English.

The present study primarily aimed to examine whether self-esteem serves as a mediator in the associations between parent–child relationships, including parental support and parent–child conflict, and resilience among adolescents. Three hundred and four Chinese adolescents were surveyed with questionnaires and structural equation modeling was adopted to test the mediational hypothesis. The results indicated that the associations between parent–child relationships and adolescent resilience were primarily mediated by self-esteem and that parental support was more robustly linked with adolescent resilience than parent–adolescent conflict. (...) The current study also tested a competitive mediational model in which resilience was the mediator and self-esteem was the outcome variable, and observed that this model was also well-established but inferior to the hypothesized mediational model. These findings extend our insight into the mechanisms underlying the associations among parent–child relationships, self-esteem, and resilience among adolescents and suggest that adolescent resilience promotion programs should focus on improving parental support in a family context and developing individual self-esteem.

It has been widely assumed and proven that a firm’s research and development investment is limited if the availability of cash flow is constrained. The purpose of this study is to verify the opposite proposition: whether firms invest heavily in R&D when more cash flow is available. This paper discusses the heterogeneous relationship between cash flow from different sources and the R&D investment of firms. The study divides the firm’s cash flow into three categories according to the business activities that (...) generate firm finance: cash flow from operating activities, cash flow from investing activities, and cash flow from financing activities. On this basis, a dynamic R&D investment model is constructed, and the relevant data for Chinese listed firms are used for the empirical research. The study finds that Chinese listed firms do not necessarily spend more cash on R&D investment, even if the availability of cash flow is not constrained. For young firms, CFO and CFI do not significantly correlate with R&D investment, and CFF significantly negatively correlates with R&D investment. For mature firms, the correlations between cash flow generated from different activities and R&D investment are nonsignificant. (shrink)

Objective: Based on how the identity of doctoral students is recognized and understood in the context of Chinese culture, we developed a doctoral identity scale using both qualitative and quantitative analyses.Methods: The initial project of the Scale was formed through qualitative analyses and expert consultation. Nine hundred and ninety-one doctoral students were officially tested, and 982 valid questionnaires were obtained. They were randomly divided into two parts, and 491 of which were assessed for item Response Theory and exploratory factor analysis (...) and 491 of which were assessed for confirmatory factor analysis. The Subjective Well-Being Scale, the Rosenberg Self-Esteem Scale, and the Psychological Sense of School Membership Scale were used to test its the criterion-related validity. One hundred and forty-one students were selected for retesting after 8 weeks.Results: The doctoral student identity questionnaire consisted of two factors identity exploration and identity commitment, explaining 57% of the total variance. The results of CFA showed that the two-factor model fitted the data well. The two dimensions of the Doctoral Student Identity Scale were significantly and positively correlated with the two dimensions of the SWB scale, the latent factor of the RSE scale, and the latent factor of the PSSM scale. Composite reliability values for exploration and commitment were 0.79 and 0.83 respectively, and the values of McDonald’s omega for exploration and commitment were 0.81 and 0.85 respectively. The test-retest reliability of the total questionnaire was 0.842.Conclusion: The Doctoral Student Identity Scale was developed with good reliability and validity, and can be used as a reliable tool for measuring the doctoral student identity. In addition, the questionnaire will provide corresponding ideas and methods for studying the identity issues of specific groups. (shrink)

We present the theory, the experimental evidence and fundamental physical consequences concerning the existence of families of undistorted progressive waves (UPWs) of arbitrary speeds 0≤ϑ<∞, which are solutions of the homogeneuous wave equation, the Maxwell equations, and Dirac, Weyl, and Klein-Gordon equations.

The field of causal learning and reasoning (largely overlooked in the target article) provides an illuminating case study of how the modern Bayesian framework has deepened theoretical understanding, resolved long-standing controversies, and guided development of new and more principled algorithmic models. This progress was guided in large part by the systematic formulation and empirical comparison of multiple alternative Bayesian models.

This study aimed to reveal the characteristics of multi-circuit brain synergy between elite tai chi chuan athletes in resting and exercise states and to provide neuroimaging evidence of improvements in brain function by motor skill training. Functional near-infrared spectroscopy was used to compare the brain activity of professional tai chi chuan athletes and beginners in resting and exercise states, and to assess functional connectivity between the prefrontal lobe and the sensorimotor zone. In the resting state, the FC between the left (...) prefrontal lobe and the right sensorimotor area in the expert group was significantly lower than that in the novice group. In the exercise state, the patterns of FC between the left prefrontal lobe and right sensorimotor area, the right prefrontal lobe and left sensorimotor area, and the left and right sensorimotor areas in the expert group were significantly lower than that in the novice group. From the resting state to the locomotor state, the expert group experienced a greater absolute value of functional connection increment between the left prefrontal cortex and right sensorimotor area, and between the left sensorimotor area and right sensorimotor area. This was positively correlated with the self-evaluation results of motor performance behavior. Under sports conditions, professional athletes’ multi-circuit brain FC strength is significantly reduced, and their elite motor skill performance supports the neural efficiency hypothesis. This may be related to the high adaptation of the brain to specific tasks and the improvement of the integration of somatic perception processing and motor function. (shrink)

Drawing on the cognitive evaluation theory, we proposed a homologous multilevel model to explore how ethical leadership influenced employees’ innovative work behavior through the mediation of intrinsic motivation at both group and individual level. With questionnaires rated by 302 employees from 34 work units of two companies in the mainland of China, we conducted multilevel analysis to examine our hypotheses. The results showed that individual innovative work behavior was positively related to both individual perception of ethical leadership and group ethical (...) leadership, while individual intrinsic motivation mediated the two relationships. Moreover, group intrinsic motivation mediated the relationship between group ethical leadership and innovative work behavior. The theoretical and practical implications were further discussed.

The inconsistent findings of past board diversity research demand a test of competing linear and curvilinear diversity–performance predictions. This research focuses on board age and gender diversity, and presents a positive linear prediction based on resource dependence theory, a negative linear prediction based on social identity theory, and an inverted U-shaped curvilinear prediction based on the integration of resource dependence theory with social identity theory. The predictions were tested using archival data on 288 large organizations listed on the Australian Securities (...) Exchange, with a 1-year time lag between diversity (age and gender) and performance (employee productivity and return on assets). The results indicate a positive linear relationship between gender diversity and employee productivity, a negative linear relationship between age diversity and return on assets, and an inverted U-shaped curvilinear relationship between age diversity and return on assets. The findings provide additional evidence on the business case for board gender diversity and refine the business case for board age diversity. (shrink)
