Recent systematic studies using newly developed genomic approaches have revealed common mechanisms and principles that underpin the spatial organization of eukaryotic genomes and allow them to respond and adapt to diverse functional demands. Genomes harbor, interpret, and propagate genetic and epigenetic information, and the three‐dimensional (3D) organization of genomes in the nucleus should be intrinsically linked to their biological functions. However, our understanding of the mechanisms underlying both the topological organization of genomes and the various nuclear processes is still largely (...) incomplete. In this essay, we focus on the functional relevance as well as the biophysical properties of common organizational themes in genomes (e.g. looping, clustering, compartmentalization, and dynamics), and examine the interconnection between genome structure and function from this angle. Present evidence supports the idea that, in general, genome architecture reflects and influences genome function, and is relatively stable. However, the answer as to whether genome architecture is a hallmark of cell identity remains elusive. (shrink)

The security of the civil aviation network is closely related to flight safety. Security situation prediction is the advanced stage of situational awareness in the civil aviation network. In this article, a prediction approach of security situations for the air traffic management network is proposed on the basis of the wavelet neural network. The proposed approach adopts the wavelet theory and neural network, combining a time-series forecasting method for the prediction of security situations in the civil aviation network. The experimental (...) results show that this approach has the advantages of fast training and high prediction accuracy. (shrink)

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)

Drawing upon a developmental perspective, we investigated the differences in power acquisition between only and non-only children as well as the mediating role of cooperative and competitive orientations and the moderating role of dependency on parents. To test our hypotheses, we conducted two field studies in 155 part-time Master of Business Administration students and 375 senior students. Results showed that: non-only children were more likely to achieve higher rank at work than only children; only children were less likely than non-only (...) children to acquire power in organizations because they scored lower in cooperative orientation; however, the mediating effect of competitive orientation was not significant; the difference in cooperative orientation between only and non-only children was smaller when dependency on parents was high, whereas it became larger when dependency on parents was low. Our research contributes to the understanding of how family structure influences individual power acquisition. (shrink)

Teachers' emotional states such as optimism and commitment have long been approved influential in second/foreign language education. Although many correlational investigations have been conducted on teacher optimism and commitment, their interaction and kinship with teachers' work engagement have been largely ignored in the literature. Considering this situation, the present mini-review aims to present the theoretical underpinnings, definitions, dimensions, and conceptualizations of these three important variables taken from positive psychology. Moreover, the present review can offer a number of practical implications for (...) EFL teachers, teacher educators, program designers, school principals, and L2 researchers, and raise their awareness of the impact of inner emotions on teachers' academic performance. Finally, research gaps and future directions are provided for eager researchers to run similar and complementary studies in EFL contexts. (shrink)

Multiple goals balancing is an important but not yet fully validated dimension of complex problem solving (CPS). The present study used process data to explore how solvers clarify goals, set priorities, and balance conflicting goals. We extracted behavioral indicators of goal pursuit from the log data of 3,201 students on the third subtask of the “Ticket” task in the PISA 2012 CPS test. Cluster analysis was used to identify 10 groups that varied in goal pursuit behavior. Logistics and least-squares regression (...) analysis were used to explore how goal pursuit affected task scores and CPS proficiency. The results showed that competent solvers clarified goals and weighed priorities more effectively. They also made trade-offs between conflicting goals. The importance of theoretically-driven log data analysis and coping strategies in the face of multiple goals conflict scenarios was discussed. (shrink)

This research investigates how two different types of nongovernmental organization (NGO)–business collaboration for green innovation impact consumers’ purchase intentions. The authors carried out three studies, whose findings show that consumers prefer collaborations in which NGOs are integrated into the product development process (NGO co-development) over those that involve corporate giving to NGOs (sales-contingent donations). They show that green credibility works as a mediator, which explains why these two types of collaboration influence consumers’ purchase intentions differently. They also identify aspirational talk (...) about a company’s future ambitions as an important boundary condition. These findings are important for literature on corporate social responsibility (CSR) communication, co-development, and co-branding and contribute to the discussion of the role of business in society.

The temporal‐focus hypothesis claims that whether people conceptualize the past or the future as in front of them depends on their cultural attitudes toward time; such conceptualizations can be independent from the space–time metaphors expressed through language. In this paper, we study how Chinese people conceptualize time on the sagittal axis to find out the respective influences of language and culture on mental space–time mappings. An examination of Mandarin speakers' co‐speech gestures shows that some Chinese spontaneously perform past‐in‐front/future‐at‐back (besides future‐in‐front/past‐at‐back) (...) gestures, especially when gestures are accompanying past‐in‐front/future‐at‐back space–time metaphors (Exp. 1). Using a temporal performance task, the study confirms that Chinese can conceptualize the future as behind and the past as in front of them, and that such space–time mappings are affected by the different expressions of Mandarin space–time metaphors (Exp. 2). Additionally, a survey on cultural attitudes toward time shows that Chinese tend to focus slightly more on the future than on the past (Exp. 3). Within the Chinese sample, we did not find evidence for the effect of participants' cultural temporal attitudes on space–time mappings, but a cross‐cultural comparison of space–time mappings between Chinese, Moroccans, and Spaniards provides strong support for the temporal‐focus hypothesis. Furthermore, the results of Exp. 2 are replicated even after controlling for factors such as cultural temporal attitudes and age (Exp. 3), which implies that linguistic sagittal temporal metaphors can indeed influence Mandarin speakers' space–time mappings. The findings not only contribute to a better understanding of Chinese people's sagittal temporal orientation, but also have additional implications for theories on the mental space–time mappings and the relationship between language and thought.

This paper’s core concern is Boris Groys’ theory of the total art of Stalinism, which is devoted to rewriting Soviet art history and reinterpreting Socialist Realism from the perspective of the equal rights between political and artistic Art Power. The aim of this article is to decode Groys and the total art of Stalinism, based on answering the following three questions: 1) why did Groys want to rewrite Soviet art history? 2) How did Groys re-narrate Soviet art history? 3) What (...) are the pros and cons of his reordering of the total art of Stalinism? Groys offers an effective paradigm that could rethink two theoretical genres: a) other Socialist Realisms inside or outside the Soviet bloc, during or after the Soviet era; b) the aesthetical rights of political artworks before, during and after the Cold War, and the historical debates about art, especially about art for art’s sake, or art for political propaganda. However, Groys’ total art of Stalinism and its core theory of the Socialist Realism frame hides some dangers of aestheticizing Stalin and Stalinism. (shrink)

ABSTRACTFilm clips are widely used in emotion research due to their relatively high ecological validity. Although researchers have established various film clip sets for different cultures, the few that exist related to Chinese culture do not adequately address positive emotions. The main purposes of the present study were to establish a standardised database of Chinese emotional film clips that could elicit more categories of reported positive emotions compared to the existing databases and to expand the available film clips that can (...) be used as neutral materials. Two experiments were conducted to construct the database. In experiment 1, 111 film clips were selected from more than one thousand Chinese movies for preliminary screening. After 315 participants viewed and evaluated these film clips, 39 excerpts were selected for further validation. In experiment 2, 147 participants watched and rated these 39 film clips, as well as another 8 excerpts chosen from the existing databases, to compare their validit... (shrink)

Employees are critical stakeholders for an organization because they directly deal with the end-users and represent the entire firm. To recognize the strategic importance of the employees, organizations create communication programs to keep employees apprised of organizational issues. In this regard, this study examined the role of communication strategies on organizational commitment. The study also investigated the mediating effect of faculty engagement between communication strategies and organizational commitment. Self-administered survey aided in acquiring data from 276 English language teachers in China. (...) The analysis of the data was conducted using SmartPLS through the Structured Equation Modeling technique. The outcome of the study demonstrated that information flow and information feedback significantly impact organizational commitment and faculty engagement. The analysis also revealed that information adequacy significantly impacts organizational commitment but has no relationship with faculty engagement. The mediation analysis demonstrated that faculty engagement mediated the relationship between information flow and organizational commitment and between information feedback and organization commitment. However, faculty engagement did not mediate the relationship between information adequacy and organizational commitment among English language teachers in China. In theoretical terms, the study contributed in terms of incorporating different communication strategies and examining their effect on organizational commitment and faculty engagement. In practical terms, this study would be beneficial for the management of the educational institutes to develop different ways of enhancing communication strategies within the institute. This study also provided directions for the future, for example, conducting the study on other subject teachers, increasing the sample, carrying out the research in a different context, and adding different mediators and moderators in the existing model.

In the contemporary epistemological literature, peer disagreement is often taken to be an instance of a more general phenomenon of “higher-order evidence.” Correspondingly, its epistemic significance is often thought to turn on the epistemic significance of higher-order evidence in general. This chapter attempts to evaluate this claim, and in doing so to clarify some points of unclarity in the current literature – both about what it is for evidence to be “higher-order,” and about the relationship between disagreement and higher-order evidence. (...) We will begin by considering some candidate definitions of “higher-order evidence,” and offering our own definition that attempts to capture the phenomenon of interest. We will then consider, in light of this definition, whether disagreement and its epistemic significance are best-understood as a kind of higher-order evidence. We’ll argue that although peer disagreement can be epistemically significant qua higher-order evidence, this role doesn’t exhaust its significance, and that it can also serve as straightforward first-order evidence. Finally, we’ll suggest that inattention to this latter point has made broadly conciliatory views about peer disagreement seem somewhat easier to resist than they in fact are. (shrink)

Public welfare fundraising has been used to collect donations for medical supplies and has played an important role in the fight against the COVID-19 pandemic. This paper studies online crowdfunding donations from the Alumni Association of Wuhan University to North American alumni; donation data are used to investigate how individuals' donation behavior is affected by the previous donation amount and information provided by the fundraising platform. First, our results show that one's donation amount is positively affected by the previous donation (...) amount. Second, the donor's positive sentiment in the message that he or she leaves, as measured by either natural language processing or a manual rating, can affect the subsequent anonymity and messages but not the subsequent donation amount. Third, anonymous donations are much smaller than non-anonymous donations. (shrink)

The importance of work stress on newcomers’ organizational socialization has been a topic of substantial interest. However, the impact mechanism of different stressors on newcomers’ organizational socialization is still in the early stages of theory development. This study, based on the theory of the dual work stress model, explored how to challenge stressors and hindrance stressors impact newcomers’ organizational socialization via the mediation of job crafting. Based on the empirical data from 247 newcomers, we found that challenge stressors positively affected (...) newcomers’ organizational socialization; on the contrary, hindrance stressors would result in negative influences. In addition, leader-member exchange enhanced the positive effect of challenge stressors on newcomers’ job crafting and further moderated the indirect influence of challenge stressors on newcomers’ organizational socialization via job crafting. These findings provide a practical guide for organizations to apply stress management and promote newcomers’ socialization. (shrink)

This paper evaluates the Hong Kong approach to consent regarding the forgoing of life-sustaining treatment for incompetent elderly patients. It analyzes the contextualized approach in the Hong Kong process-based, consensus-building model, in contrast to other role-based models which emphasize the establishment of a system of formal laws and a clear locus of decisional authority.Without embracing relativism, the paper argues that the Hong Kong model offers an instructive example of how strategic ambiguities can both make good sense within particular cultural context (...) and serve important moral goals.

Previous studies have demonstrated positive correlations between children’s interpersonal trust and social adjustment. However, the psychological mechanism underlying this effect is still unclear. The current study tested the indirect roles of teacher–student relationships from both students’ and teachers’ perspectives in a Chinese context. In total, 709 pupils from grade three to grade five, and their 17 head teachers from a Chinese public primary school participated in this study. The Children’s Generalized Trust Beliefs Scale, Social Adjustment Scale for Children and Adolescents, (...) and Teacher–Student Relationship Questionnaire were used in this study. All these variables were correlated with each other. Structural equation models showed that the interpersonal trust indirectly influenced social adjustment through the teacher–student relationship from students’ perspectives, while the teacher–student relationship from teachers’ perspectives did not play an indirect role. These findings suggest that the teacher–student relationship perceived by students is more important for children’s social adjustment than that perceived by teachers. Both parents and teachers should pay more attention to developing children’s interpersonal trust, build better teacher–student relationships, and focus more on how children feel about the relationship.
