To test our hypotheses, an online survey was conducted via a large number of 703 employees working in public organizations in southwest China. Results yielded from the structural equation modeling analysis via AMOS (24.0) indicated that the effect of servant leadership on employee resilience was fully mediated by organizational identification and professional identity, respectively. Besides, the association between servant leadership and employee resilience was sequentially mediated from organizational identification to professional identity, and from professional identity to organizational identification. This study provides the first evidence of the predictive effect of servant leadership on employee resilience through organizational identification and professional identity, highlighting the significance of social identity for building and maintaining employees' resilience in coping with challenges posed by COVID-19.

The current study, based on the PERMA model, proposed and examined a hypothetical model exploring the effects of academic self-efficacy, positive relationships, and psychological resilience on university students' life satisfaction. We collected data from a large sample of 1,089 university students in southwest China. The participants completed a battery of self-report questionnaire items measuring academic self-efficacy, positive relationships, psychological resilience, and life satisfaction. The results of the structural equation modeling analysis demonstrated a good fit for our data, suggesting that academic self-efficacy positively predicted university students' life satisfaction through two independent mediators: positive relationships and psychological resilience. Findings yielded from the empirically validated hypothetical model add value to and enrich the PERMA model within a group of Chinese university students. The implications and practical suggestions for improving university students' life satisfaction are discussed in light of these findings.

A total of 901 frontline employees working in a construction engineering company in China participated in this study. They were asked to respond to a battery of questionnaires comprising Trust Scale (affective-based, cognitive-based, and competence-based), Flow Proneness Questionnaire (FPQ), Organizational Identification Scale, Authentic Leadership Questionnaire, and Employee Resilience Scale. Results of structural equation modeling indicated that: (1) Authentic leadership positively predicted employee resilience in the COVID-19 pandemic, directly and indirectly. (2) As for the indirect relationship, two parallel mediation effects and one chain mediation were detected: employees' flow at work and organizational identification respectively and dependently mediated the relationship between authentic leadership and employee resilience; trust and organizational identification played as a chain mediation role within authentic leadership-employee resilience association. The study provides empirical evidence for organizations' resilience-building and leadership training programs. Findings also contribute to the literature by facilitating flow intervention, promoting organizational identification and trust to enhance the effect of authentic leadership in promoting positive psychological functioning of employee resilience. Limitations with respect to future research directions were also outlined.

Blockchain-enabled Internet of Medical Things (BIoMT) has attracted significant attention from academia and healthcare organizations. However, the large amount of medical data involved in BIoMT has also raised concerns about data security and personal privacy protection. To alleviate these concerns, blind signature technology has emerged as an effective method to solve blindness and unforgeability. Unfortunately, most existing blind signature schemes suffer from the security risk of key leakage. In addition, traditional blind signature schemes are also vulnerable to quantum computing attacks. Therefore, it remains a crucial and ongoing challenge to explore the construction of key-secure, quantum-resistant blind signatures. In this paper, we introduce lattice-based forward-secure blind signature (LFSBS), a lattice-based forward-secure blind signature scheme for medical privacy preservation in BIoMT. LFSBS achieves forward security by constructing a key evolution mechanism using a binary tree structure. This mechanism ensures that even if future encryption keys are leaked, past data can still remain secure. Meanwhile, LFSBS realizes post-quantum security based on the hardness assumption of small integer solution (SIS), making it resistant to potential quantum computing attacks. In addition, we formally define and prove the security of LFSBS in a random oracle model, including blindness and forward-secure unforgeability. Comprehensive performance evaluation shows that LFSBS performs well in terms of computational overhead, with a reduction of 22%–73% compared to previous schemes. [ABSTRACT FROM AUTHOR]

Given the severe impact of the global COVID-19 pandemic, there is an urgent need for scientific research on strategies to help vulnerable populations, such as the elderly, cope effectively. Drawing upon the weak ties theory and information literacy, this study started with preliminary interviews to explore potential factors influencing the positive coping behavior of a group of elderly Chinese individuals. It further disentangled the impact of social networks (including network size, network strength, and network heterogeneity) and information acquisition on the elderly's positive coping behavior during the COVID-19 pandemic and elucidated their underlying mechanisms. The hypotheses were tested by surveying 916 individuals aged 60 to 96 in southwest China. Structural equation modeling analysis conducted using AMOS (24.0) revealed that social network (network strength and heterogeneity) and information acquisition were directly associated with positive coping behavior, respectively. Perceived community support mediated such associations. Findings enrich the theoretical literature and provide new perspectives on how to help the elderly cope with health crises by enhancing social network, information acquisition, and perceived community support. Plain language summary: Disentangle the elderly's positive coping behavior in times of COVID-19: Perspectives from the social network, information acquisition, and perceived community support Given the far-reaching impact of the global COVID-19 pandemic, scientific research, and corresponding suggestions on how to help the elderly (the vulnerable population group) cope with positively are emergently needed. To this end, this study conducted a survey of 916 people using a questionnaire survey method and a structural equation model, exploring in depth the factors that may be affected by the active coping behavior of the Chinese elderly people during the COVID-19 pandemic. This research indicates that social networks, information acquisition, and community support can prompt them to take more active response behaviors. Findings from this research stimulate more research on how vulnerable groups such as the elderly can improve coping behavior and ability during the COVID-19 pandemic. Unavoidably, sample selection was only conducted in one provincial capital city in China, and issues such as the applicability of the scale caused by cultural differences need to be noted in future research.

The focus of this study is bystanders' behavior and their willingness to intervene in cases of intimate partner violence (IPV) in three different countries (China, Italy, and Ethiopia), considering individual and social factors (i.e., right-wing Authoritarianism, masculinity ideology, and gender). The Italian sample was made up of 192 participants (56% male). The Chinese sample was made up of 274 participants (66% female). The Ethiopian sample was made up of 161 participants (53.3% female). Participants completed the Male Role Norms Inventory–Short Form, the Right-wing Authoritarianism Scale, and the Willingness to intervene in cases of IPVAW. The Chinese model suggested how masculinity ideology is negatively associated with "reporting the incident to the authorities" factor, and positively with "not my business" factor. Right-wing authoritarianism is positively associated with "reporting the incident to the authorities" factor. The Italian model suggested how masculinity ideology was positively related to the "reporting the incident to the authorities" factor, and gender was negatively related to "not my business" factor, and positively related to "personal involvement" factor. The Ethiopian model suggested how masculinity ideology is positively associated with "personal involvement in the case" factor and gender is positively associated with the "reporting the incident to the authorities" factor. Masculine ideologies, authoritarian personality characteristics, and gender are predisposing factors toward bystander attitudes when confronted with cases of intimate partner violence. Our findings highlight key areas of focus to help raise awareness related to IPV cases, and policy aimed at promoting prosocial society. [ABSTRACT FROM AUTHOR]

Purpose: This paper aims to examine the day-to-day within-person associations between employees' flow experience and organizational identification within the rarely studied context of construction engineering project organizations. Design/methodology/approach: In this daily diary design, the authors surveyed 204 (Mage = 28.3, SD = 5.69) employees of a state-owned construction engineering project organization in southwest China via the online questionnaires comprising flow and organizational identification scales once daily on each workday for three consecutive weeks, which yielded 3,060 data entries. The authors then tested the temporal directionality between flow and organizational identification with multilevel time-series cross-lagged path analysis using Mplus 8.3. Findings: Daily flow experience was linked positively with same-day organizational identification. Importantly, flow experience on the previous day predicted organizational identification on a subsequent day, but not vice versa. Practical implications: This study suggests that construction engineering project managers should implement interventions fostering the employees' flow experience to promote organizational identification, with important implications for organizations aiming at flourishing workforces by facilitating organizational identification through implementing flow strategies. Originality/value: There is a dearth of diary studies on flow and organizational identification specific to construction engineering project employees. The authors' findings provide concrete evidence of the fluctuant nature of daily flow experience and organizational identification as well as their dynamic predictive pathway relationship.
