Stressful life events and subjective well-being are negatively related, but there is little research in the current literature exploring the mediating and moderating mechanisms underlying this association, especially for female adolescents in vocational schools who are subjected to undesirable life events. In the present study, we examined the mediating role of depression in the association between stressful life events and female adolescents’ subjective well-being, as well as the moderating role of perceived social support in the direct and indirect relations involved. (...) The participants were 1,096 vocational school female adolescents, who completed the questionnaires regarding stressful life events, subjective well-being, depression, and perceived social support. The results showed that depression partially mediated the relation between stressful life events and subjective well-being. Importantly, perceived social support moderated the direct link between stressful life events and subjective well-being, and the indirect link between stressful life events and depression, but not the indirect link between depression and subjective well-being. Especially, female adolescents high in perceived social support displayed higher levels of subjective well-being and lower levels of depression in facing with stressful life events than those low in perceived social support. These findings highlight the mechanisms underlying the relationship between stressful life events and subjective well-being in vocational school female adolescents. (shrink)

Finance ethics have drawn increasing attention from both government regulators and academic researchers. This paper addresses the issue of insider trading ethics. Previous studies on insider trading ethics have failed to provide convincing arguments and consistent results. In particular, the arguments against insider trading are based primarily on moral and philosophical grounds and lack empirical rigor. This study intends to establish and examine the relationship between the ethical issue and economic issue of insider trading. We argue that the ethics of (...) insider trading is in essence an economic rather than a moral issue. It is so far not clear to what extent insider trading may increase or decrease shareholders wealth. Until then, we must take care to avoid over-regulating insider trading. (shrink)

The present study investigated the mediating role of negative emotion in the relationship between cybervictimization and non-suicidal self-injury, and the moderating role of friendship quality in the indirect relationship. This model was tested with 1,326 Chinese adolescents who suffered from cyberbullying in the last 1 year; 727 were boys and 591 were girls, and their mean age was 13.67 years. Participants filled out questionnaires regarding cybervictimization, negative emotion, friendship quality, and non-suicidal self-injury. After demographic variables were controlled, cybervictimization was significantly (...) positively associated with non-suicidal self-injury. Mediation analysis revealed that negative emotion partially mediated the association between cybervictimization and non-suicidal self-injury. Moderated mediation analysis further indicated that the mediated path was weaker for adolescents with higher levels of friendship quality. These findings underscore the importance of identifying the mechanisms that moderate the mediated path between cybervictimization and non-suicidal self-injury among adolescents. (shrink)

This paper proposes an extended version of the interventionist account for causal inference in the practical context of biological mechanism research. This paper studies the details of biological mechanism researchers’ practices of assessing the evidential legitimacy of experimental data, arguing why quantity and variety are two important criteria for this assessment. Because of the nature of biological mechanism research, the epistemic values of these two criteria result from the independence both between the causation of data generation and the causation in (...) question and between different interventions, not techniques. The former independence ensures that the interventions in the causation in question are not affected by the causation that is responsible for data generation. The latter independence ensures the reliability of the final mechanisms not only in the empirical but also the formal aspects. This paper first explores how the researchers use quantity to check the effectiveness of interventions, where they at the same time determine the validity of the difference-making revealed by the results of interventions. Then, this paper draws a distinction between experimental interventions and experimental techniques, so that the reliability of mechanisms, as supported by the variety of evidence, can be safely ensured in the probabilistic sense. The latter process is where the researchers establish evidence of the mechanisms connecting the events of interest. By using case studies, this paper proposes to use ‘intervention’ as the fruitful connecting point of literature between evidence and mechanisms. (shrink)

Potentiality and actuality are a pair of fundamental categories of the materialist dialectic. Here I would like primarily to examine potentiality.

Purpose – This study aims to investigate the perceptions, acceptance, usage and access to social media by students and academics in higher education in informatics programs in Malaysia. A conceptual model based on Connectivism and communities of practice learning theory was developed and were used as a basis of mapping the research questions to the design frameworks and the research outcomes. A significant outcome of this study will be the development of a design framework for implementing social media as supporting (...) tools for student engagement and teaching and learning of informatics programs in higher education institutions in Malaysia. Design/methodology/approach – A mixed-method research methodology with a significant survey research component was employed for this research. This methodology focused on collecting and analyzing quantitative and qualitative data to better understand the research problems. For this study, a mixed-method sequential transformative research strategy based on a QUAN-Qual model was used in the data collection process. Mixed-method research methodology is considered to be most appropriate for this study, as it allows the researcher to gather multiple forms of data from diverse audiences such as educators, administrators and students. Findings – The findings show the close matched of the ownership, amount of hours spent online, types of social media technologies used and pattern of usage between informatics and non-informatics students. It also shows that many students and instructors have started to explore and accept the use of SMTs as a tool for engaging with their institution and their peers as well as for teaching and learning purposes. Innovative institutions need to understand the critical success factors and the barriers that restrict the implementation of SMTs within the HEI to take advantage of the opportunities offered by SMTs in higher education. Research limitations/implications – The surveys and interview participant, in part, are self-selecting, so the data collected cannot be claimed to be representative of the population. However, because of the relatively large number of participants, it can be considered that the findings are indicative. Other limitation includes the depth of data that can be collected using this methodology. Practical implications – There is wide range of social media usage in educational settings now being reported, but many issues are still unexamined. Limited studies have been focusing on the educators’ readiness, acceptance or refusal in integrating social media into their courses, the perceived effectiveness of the tools and student outcomes for their learning. The central outcome of this research will be the development of a design framework that will be used as a guide for Malaysian HEIs and informatics academics to engage students using SMTs in creating effective learning communities for informatics programs. Social implications – The framework will have implication for the social interaction and engagement of students with their institution. Originality/value – Very little work has been reported on student and academic engagement, their perspectives and perceived effectiveness of social media usage in higher education, especially in the Malaysia context. Most of the research focused only on the quantitative research with students from universities in the USA and Australia, with an emphasis mainly on student’s perception and acceptance. There are calls for more research to examine how social media is perceived and accepted by students and academics for teaching and learning, especially in Malaysia. (shrink)

ABSTRACTResearch on the development of selective trust has shown that young children do not indiscriminately trust all potential informants. They are likely to seek and endorse information from individuals who have proven competent or benign in the past. However, research on trust among adults raises the possibility that children might also be influenced by the emotions expressed by potential informants. In particular, they might trust individuals expressing more positive emotion. Indeed, young children’s trust in particular informants based on their past (...) behaviour might be undermined by their currently expressed emotions. To examine this possibility, we tested the selective trust of fifty 4- and 5-year-olds in two steps. We first confirmed that children are likely to invest more trust in individuals expressing more positive emotion. We then showed that even if children have already formed an impression of two potential informants based on their behavioural record, their choices about whose claims to trus... (shrink)

Gender roles are anti-dichotomous and malleable social constructs that should theoretically be constructed independently from biological sex. However, it is unclear whether and how the factor of sex is related to neural mechanisms involved in social constructions of gender roles. Thus, the present study aimed to investigate sex specificity in gender role constructions and the corresponding underlying neural mechanisms. We measured gender role orientation using the Bem Sex-Role Inventory, used a voxel-based global brain connectivity method based on resting-state functional magnetic (...) resonance imaging to characterize the within-network connectivity in the brain reward network, and analyzed how the integration of the reward network is related to gender role scores between sex groups. An omnibus analysis of voxel-wise global brain connectivity values within a two-level linear mixed model revealed that in female participants, femininity scores were positively associated with integration in the posterior orbitofrontal cortex and subcallosal cortex, whereas masculinity scores were positively associated with integration in the frontal pole. By contrast, in male participants, masculinity was negatively correlated with integration in the nucleus accumbens and subcallosal cortex. For the first time, the present study revealed the sex-specific neural mechanisms underlying distinct gender roles, which elucidates the process of gender construction from the perspective of the interaction between reward sensitivity and social reinforcement.

Distinct from nominal metaphors, predicate metaphors entail metaphorical abstraction from concrete verbs, which generally involve more action and stronger motor simulation than nouns. It remains unclear whether and how the concrete, embodied aspects of verbs are connected with abstract, disembodied thinking in the brains of L2 learners. Since English predicate metaphors are unfamiliar to Chinese L2 learners, the study of embodiment effect on English predicate metaphor processing may provide new evidence for embodied cognition and categorization models that remain controversial, and (...) offer practical insights into L2 metaphor processing and pedagogy. Hence, we aim to investigate whether the embodiment of verbs, via the activation of sensorimotor information, influences two groups of L2 learners during their comprehension of conventional and novel predicate metaphors. The results show a significant effect of embodiment: a stronger facilitation for novel predicate metaphors in both higher-level and lower-level groups, and a weaker facilitation for conventional predicate metaphors in the lower-level group. The findings demonstrate preliminary evidence for a graded effect of embodiment on predicate metaphors processing, modulated by L2 proficiency and metaphor novelty. The study supports a hybrid view of embodied cognition and reveals that sensorimotor aspects of verbs may be the intermediate entity involved in the indirect categorization. (shrink)

Media guidelines on safe suicide-related reporting are within the suicide prevention armamentarium. However, implementation issues beleaguer real-world practice. This study evaluated the perspectives of the Malaysian media community, persons with lived experience of suicidal behavior, and mental health professionals on suicide-related reporting in terms of the impact, strategies, challenges, and the implementation of guidelines on safe reporting. Three focus group discussions of purposively sampled Malaysian media practitioners, PLE, and MHP were audio-recorded, transcribed, coded and thematically analyzed. Inclusion criteria were: English (...) fluency, no clinical depression or suicidal ideation, no recent previous suicide attempts or suicide bereavement. Three major themes emerged: Unsafe Reporting; Impact; and Safe Reporting. Most described current reporting as unsafe by being potentially triggering to media users and may contribute to contagion effect. Positive impacts identified included raised awareness toward suicide and its prevention. Unsafe reporting was attributed to inadequate awareness, knowledge, and guidance, lack of empathy and accountability, job-related factors, popularity-seeking, lack of monitoring and governance, and information source with unsafe content. Majority agreed on how suicide stories should be framed to produce a safe report. The media community diverged on how detailed a suicide story should be. Safe reporting challenges included difficulties in balancing beneficial versus harmful details, social media ubiquity and its citizen reporters. Participants suggested these safe reporting strategies: stakeholder engagement, educational approaches, improving governance and surveillance, and guidelines revision. Most acknowledged the relevance of guidelines but were unaware of the existence of local guidelines. Implementation challenges included the dilemma in balancing media industry needs vis-à-vis safe reporting requirements, stakeholder engagement difficulties and social media regulation. There is poor awareness regarding safe suicide-related reporting across all groups. PLE and MHP were negatively impacted by current unsafe messaging which aggravated trauma and grief reactions. Postvention support gaps for mental health professionals were highlighted. Safe reporting promotion strategies should include stakeholder engagement to increase awareness on minimizing Werther and maximizing Papageno effects. Strategic re-examination and dissemination of local media guidelines to address new media issues, and effective surveillance mechanisms, are crucial in sustainable improvement of safe reporting practices.

The energy-limited time-varying formation control problem of second-order multiagent systems is addressed for both leaderless and leader-following communication topologies in this paper. Different from the previous results, the joint consideration of energy limitation and formation design is more challenging and practical. First, an ETVF control protocol is presented, and the total energy supply is pregiven and limited, which is more common in practical applications. Then, by an orthogonal transformation, the formation control problem is converted into the consensus stabilization problem for (...) second-order leaderless MAS, where sufficient conditions for the ETVF are derived by joint design of control gains and the total energy. At the same time, the explicit formula that forms the formation center function is obtained to depict the macroscopic movement of the multiagent system as a whole. Moreover, the proposed method is also extended to the leader-following communication structure. Finally, two examples are given to verify the effectiveness of our theoretical results. (shrink)

In 1908, the first and second chapters of Kropotkin’s Mutual Aid were first translated into Chinese by Li Shizeng, greatly influencing Chinese anarchists. Li Shizeng followed Kropotkin’s scientific argument of anarchism and strengthened the viewpoint for praising “public” and suppressing “private”. When translating Kropotkin’s thoughts, Li Shizeng focused on political revolution, glossing over the criticism of the capitalist economy, and barely referenced Kropotkin’s original anarchist communist ideology.

This paper reviews the studies of Japanese society and culture undertaken by Hong Kong-based sociologists and scholars in related disciplines. It presents information on research projects funded by the Research Grants Council, Social Sciences Citation Index (SSCI), and Arts and Humanities Citation Index (A&HCI) journal articles, authored and edited books, book chapters, non-SSCI and non-A&HCI journal articles, as well as master and doctoral theses written by scholars and graduate students associated with Hong Kong's major universities. It is found that the (...) main topics of research are Japan's capitalist development and corporate growth, meanings and social ramifications of traditional and popular culture, education, gender, and marriage, as well as aspects of work and employment, whereas the major research methods include document analysis, ethnography, and in-depth interviews. The limited amount of research and the preoccupation with economic development and popular culture reflect in part Hong Kong's unique political conditions and the government's indifference to the pursuit of social and political policy analysis. In recent years, the growth of academic exchanges between scholars in Hong Kong, Japan, and other East Asian regions and the heightened emphasis by university administrators on academic research will hopefully bring about advancements in such academic endeavors.

This paper discusses the ethical implications of racism and some of the various costs associated with racism occurring at the institutional level. We argue that, in many ways, the laws, social structures, and institutions in Western society have operated to perpetuate the continuation of historical legacies of racial inequities with or without the intention of individuals and groups in society. By merely maintaining existing structures, laws, and social norms, society can impose social, economic, and health costs on racial minorities that (...) impinge on their well-being and human dignity. Based on a review of multidisciplinary research on racism, particularly focusing on healthcare, we demonstrate how institutional racism leads to social and economic inequalities in society. By positing institutional racism as the inherent cause of avoidable disparities in healthcare, this paper draws attention to the ethical significance of racism, which remains a relatively neglected issue in bioethics research.

In a series of pre-registered studies, we explored (a) the difference between people’s intuitions about indeterministic scenarios and their intuitions about deterministic scenarios, (b) the difference between people’s intuitions about indeterministic scenarios and their intuitions about neurodeterministic scenarios (that is, scenarios where the determinism is described at the neurological level), (c) the difference between people’s intuitions about neutral scenarios (e.g., walking a dog in the park) and their intuitions about negatively valenced scenarios (e.g., murdering a stranger), and (d) the difference (...) between people’s intuitions about free will and responsibility in response to first-person scenarios and third-person scenarios. We predicted that once we focused participants’ attention on the two different abilities to do otherwise available to agents in indeterministic and deterministic scenarios, their intuitions would support natural incompatibilism—the view that laypersons judge that free will and moral responsibility are incompatible with determinism. This prediction was borne out by our findings. (shrink)

The processes of learning and memory have traditionally been studied in large experimental organisms (Aplysia, mice, rats and humans), where well‐characterized behaviors are easily tested. Although Drosophila is one of the most experimentally tractable organisms, it has only recently joined the others as a model organism for learning and memory. Drosophila behavior has been studied for over 20 years; however, most of the work in the learning and memory field has focused on initial learning, because establishing memory in Drosophila has (...) not been as straightforward as in other organisms. A major recent advance in this field has been the development of a training protocol that induces long‐term memory in flies. This made possible experiments that implicated the Drosophila CREB gene as a critical component in the consolidation of long‐term memory, and paves the way for future experiments utilizing the well developed tools in Drosophila. This review will briefly summarize what is known in the field of Drosophila learning and memory to date, and discuss why the unique aspects of this field make traditional approaches difficult and reward the use of alternative paths of experimentation.

Fourth-order autonomous nonlinear differential equations can exhibit chaotic properties. In this study, we propose a family of fourth-order chaotic systems with infinite equilibrium points whose equilibria form closed curves of different shapes. First, the phase diagrams and Lyapunov exponents of the system family are simulated. The results show that the system family has complex phase diagrams and dynamic behaviors. Simulation analysis of the Poincarè mapping and bifurcation diagrams shows that the system has chaotic characteristics. The circuit simulation model is constructed (...) and simulated in Multisim. The circuit simulation results coincide with the numerical simulation results, which verifies the circuit feasibility of the system. Then, based on Lyapunov stability theory and the adaptive control method, the synchronous control of the system with infinite equilibria is designed. Numerical simulation results verify that the system synchronization with the adaptive control method is well. Finally, the synchronous drive system is used for image encryption, the response system is used for decryption, and color image encryption is realized by combining deoxyribonucleic acid coding and operating rules. Therefore, this study not only enriched the research on infinite equilibria chaotic systems but also further expanded secure communication technology by combining chaotic synchronization control and DNA coding in image encryption.
