Abstract

Purpose

Financial asset return series usually exhibit nonnormal characteristics such as high peaks, heavy tails and asymmetry. Traditional risk measures like standard deviation or variance are inadequate for nonnormal distributions. Value at Risk (VaR) is consistent with people's psychological perception of risk. The asymmetric Laplace distribution (ALD) captures the heavy-tailed and biased features of the distribution. VaR is therefore used as a risk measure to explore the problem of VaR-based asset pricing. Assuming returns obey ALD, the study explores the impact of high peaks, heavy tails and asymmetric features of financial asset return data on asset pricing.

Design/methodology/approach

A VaR-based capital asset pricing model (CAPM) was constructed under the ALD that follows the logic of the classical CAPM and derive the corresponding VaR-β coefficients under ALD.

Findings

ALD-based VaR exhibits a minor tail risk than VaR under normal distribution as the mean increases. The theoretical derivation yields a more complex capital asset pricing formula involving β coefficients compared to the traditional CAPM.The empirical analysis shows that the CAPM under ALD can reflect the β-return relationship, and the results are robust. Finally, comparing the two CAPMs reveals that the β coefficients derived in this paper are smaller than those in the traditional CAPM in 69–80% of cases.

Originality/value

The paper uses VaR as a risk measure for financial time series data following ALD to explore asset pricing problems. The findings complement existing literature on the effects of high peaks, heavy tails and asymmetry on asset pricing, providing valuable insights for investors, policymakers and regulators.

Abstract

Purpose

This study aims to fabricate a novel electromagnetic interference (EMI) shielding composite aerogel with both thermal insulation and high temperature warning functions.

Design/methodology/approach

An emerging bio-based polypyrrole (PPy) gel/Fe3O4/calcium alginate (PFC) EMI shielding composite aerogel was prepared by freeze-drying and in situ polymerization method. First, Fe3O4/calcium alginate (CA) aerogel was obtained by freeze-drying the Fe3O4/CA mixture. Then, PPy/Fe3O4/CA was obtained by synthesizing PPy on the surface of CA/Fe3O4 aerogel through in situ polymerization. Finally, PPy/Fe3O4/CA was immersed in porphyrin solution (cross-linking agent) to get the final PFC EMI shielding composite aerogel.

Findings

Due to the matched impedance between Fe3O4 and PPy, the EMI shielding performance of PFC composite aerogel can reach up to −8 dB. In addition, the PFC EMI shielding composite aerogel also shows excellent self-extinguishing and thermal insulation properties. After leaving the flame, the burning PFC aerogel is quickly extinguished. When the PFC aerogel is placed on the heating plate at 230 °C, the temperature on the side of the aerogel away from the heating plate is only 90.3 °C after 5 min of heating. The electrical resistance of the PFC composite aerogel can be reduced from 3.62 × 104 O to 5 × 102 O to trigger the warning light after 3 s of exposure to the alcohol lamp flame. This reversible thermal resistance response characteristic can be used to give an early warning signal when the PFC encounters high temperature or flame.

Originality/value

This work provides a novel strategy for designing a multifunctional EMI shielding composite aerogel with repeatable high temperature warning performance. This PFC composite aerogel shows potential applications in the prevention of material combustion in high temperature electromagnetic environments.

Abstract

Purpose

This study aims to explore the influence of green participative leadership on hotel employees’ pro-environmental behavior. Additionally, we seek to analyze the mediating role of green self-efficacy in this relationship while examining how environmental awareness moderates the connection between green participative leadership and green self-efficacy.

Design/methodology/approach

In this study, we distributed questionnaires to 546 employees working in the Chinese hotel industry. We used partial least squares structural equation modeling (PLS-SEM) to analyze the data and test the hypothesized relationships in our model.

Findings

The present study shows that green participative leadership positively influences employees’ pro-environmental behavior, with this relationship being partially mediated by green self-efficacy. Furthermore, environmental awareness significantly moderates the connection between green participative leadership and green self-efficacy.

Practical implications

The findings of this study offer valuable insights for hotel industry managers and policymakers in developing effective strategies for fostering a sustainable work environment. By embracing green participative leadership, hotels can inspire and engage employees to adopt environmentally friendly practices, ultimately contributing to the hotel’s overall sustainability.

Originality/value

This research expands the existing literature by proposing an integrative model that connects green participative leadership, green self-efficacy, environmental awareness and pro-environmental behavior. As a pioneering study within the Chinese hotel industry, it offers unique contextual insights that can help advance environmental sustainability in this sector.

Abstract

Purpose

This study aims to investigate the relationship between individual-level psychological resources and team resilience in the context of expatriate project management teams. It seeks to understand how personal psychological resources contribute to team resilience and explore the dynamic evolution mechanism of team resilience. The goal is to enhance team resilience among expatriates in a BANI (Brittle, Anxious, Nonlinear, and Incomprehensible) world, where organizations face volatile and uncertain conditions.

Design/methodology/approach

An online survey was applied for data collection, and 315 valid samples from Chinese expatriates in international construction projects were utilized for data analysis. A structural equation model (SEM) examines the relationships between personal psychological resources and team resilience. The study identifies five psychological factors influencing team resilience: Employee Resilience, Cross-cultural Adjustment, Self-efficacy, Social Support, and Team Climate. The hypothesized relationships are validated through the SEM analysis. Additionally, a fuzzy cognitive map (FCM) is constructed to explore the dynamic mechanism of team resilience formation based on the results of the SEM.

Findings

The SEM analysis confirms that employee resilience, cross-cultural adjustment, and team climate positively impact team resilience. Social support and self-efficacy also have positive effects on team climate. Moreover, team climate is found to fully mediate the relationship between self-efficacy and team resilience, as well as between social support and team resilience. The FCM model provides further insights into the dynamic evolution of team resilience, highlighting the varying impact effects of antecedents during the team resilience development process and the effectiveness of different combinations of intervention strategies.

Originality/value

This study contributes to understanding team resilience by identifying the psychological factors influencing team resilience in expatriate project management teams. The findings emphasize the importance of social support and team climate in promoting team resilience. Interventions targeting team climate are found to facilitate the rapid development of team resilience. In contrast, interventions for social support are necessary for sustainable, long-term high levels of team resilience. Based on the dynamic simulation results, strategies for cultivating team resilience through external intervention and internal adjustment are proposed, focusing on social support and team climate. Implementing these strategies can enhance project management team resilience and improve the core competitiveness of contractors in the BANI era.

Abstract

Purpose

This study aims to explore the capabilities, limitations and potential of ChatGPT applicable to online reference services in academic libraries.

Design/methodology/approach

This study used the method of qualitative content analytics to assess the general capabilities of ChatGPT applicable in academic libraries. Two experienced academic librarians had face-to-face interactions with ChatGPT by asking ten most common questions often asked by faculty and students at the Georgia Southern University Libraries (https://library.georgiasouthern.edu/). To examine the ChatGPT’s applicability and capability, they also compared the ChatGPT with a popular online chat reference tool called LibChat, which is now widely used in academic libraries in 91 countries worldwide.

Findings

It was found that as an artificial intelligence (AI)-powered real-time chatbot ChatGPT could effectively provide faculty and students with general guidance on locating the needed information resources and services in academic libraries, though its responses might not be accurate or truthful all the time. Embedded into the LibAnswers system of the Springshare’s products (www.springshare.com/libanswers/), LibChat serves as a real-time online chat tool used by academic libraries for reference services, but it is only available during the regular librarians' duty hours. This technical limitation does not meet the dynamic needs of faculty, students, staff, and local community users. Only well-optimized AI-driven chat products like ChatGPT could provide 24/7 online services to support uninterrupted academic library services in the future.

Research limitations/implications

This study only examined the general capability and potential of ChatGPT3.5 in specific subject areas. Additional studies are needed to further explore how the latest capabilities of ChatGPT4.0 or newer version, such as its text-to-image, text-to-speech, text-to-text, text-to-video and Web search, could impact future reference services of academic libraries. ChatGPT’s primary optimization and upgrades in the future may also change and impact this study's findings. The comparison between ChatGPT and LibChat presents a significant breakthrough of the generative AI technology in academic libraries. This comparative study encourages more academic experts, faculty, librarians and scholars to track the advance of generative AI applications, including ChatGPT, adopted in academic learning environments. In addition, the ChatGPT's complete capability and potential enhanced and integrated in the future may go beyond what this study evaluated.

Originality/value

This study examined the strengths and weaknesses of ChatGPT applicable to reference services of academic libraries. Through a comparison between ChatGPT and LibChat, this study suggests that optimized AI online chatbots still have a long way to go to meet the dynamic needs of faculty and students in the ever-changing academic learning environments. To contribute to the existing research literature focusing on the rise of generative AI tools such as ChatGPT, this study provides a valuable reference for the applicability of generative AI applications in academic libraries to promote more library creation and innovation in the coming years of the 21st century.

Abstract

Purpose

Although various stakeholder groups frequently advocate and call for greater heterogeneity among directors and managers, it remains unknown whether team heterogeneity can be beneficial for audit committee to exercise the auditor selection functions. This study aims to address this question.

Design/methodology/approach

Drawing on a sample of domestically listed nonfinancial A-share firms in China from 2008 to 2022, the authors empirically examine whether and how firm’s audit committee heterogeneity associates with the selection of auditors.

Findings

Firms with higher levels of audit committee heterogeneity are more likely to be associated with lower-quality auditors. Further examination reveals the mediating role of risk-taking: higher levels of heterogeneity are associated with higher levels of risk-taking, influencing firms to employ lower-quality auditors. Moreover, the authors document that increased audit committee heterogeneity is associated with more audit committee meetings and lower audit efficiency, and that hiring lower-quality auditors can influence the market value of firms with high audit committee heterogeneity.

Originality/value

To the best of the authors’ knowledge, this study is the first to examine whether and how audit committee erogeneity associates with the selection of auditors. Moreover, because China is a high-power distance, collectivism-oriented, more relations-based (i.e. guanxi-based) than rules-based society, it is critical to examine the influence of team heterogeneity based on the unique cultural context and transitional nature of China’s business environment.

Abstract

Purpose

This paper aims to examine the dynamics between Hong Kong’s domestic sporting needs and its regional aspirations as a “hub” for sport and culture, which have created challenges and contradictions for the optimal provision of relevant infrastructure. These have become particularly evident during the COVID-19 pandemic, when local restrictions have undermined Hong Kong’s appeal as an event destination and hindered access and utilization of venues. In recent years, policies in this area have mainly focused on the development of a new sports park on the former airport runway in Kai Tak, which has acquired additional significance in the city’s quest for post-pandemic economic recovery. Simultaneously, any noncommercial land use in Hong Kong, one of the most densely populated cities in the world, faces intense scrutiny over a perceived scarcity of space.

Design/methodology/approach

By drawing upon concepts from urban studies and policy studies, the paper explores a presumed preference for commodified sporting landscapes and provides an interdisciplinary approach to enhance the author’s understanding of sport policy and infrastructure. This is achieved through direct comparisons of two case studies, and by building on and expanding a multidimensional evaluative framework of sustainability that can avoid economic reductionism.

Findings

This paper finds that Hong Kong’s sport policy framework exhibits unbalanced consideration when it comes to the planning and development of relevant infrastructure.

Originality/value

By acknowledging the interrelatedness and similarity between sports and culture, the paper may further test the adaptability of cultural policy concepts for the analysis of Hong Kong’s sports policy. As such, it aims to bring the usually separated study of cultural and sport policy within a comparable framework.

Abstract

Purpose

The present study aims to examine the lived experience of undergraduate students in learning entrepreneurship education through online coach-peer conference at a university in Indonesia, in order to explore the lived experience of undergraduate students in developing entrepreneurial self-efficacy during the COVID-19 pandemic.

Design/methodology/approach

Anchored in a phenomenological case study, the student participants were interviewed using online platforms such as WhatsApp and Zoom. To triangulate the data, photographs were taken during observation while the participants were engaged in the online learning process. The interview data were transcribed, interpreted using interpretative phenomenological analysis and thematically analyzed.

Findings

This study showed that participants built businesses with (1) the formation of entrepreneurial attitudes and behaviors, (2) increased their entrepreneurial literacy, and (3) increased their involvement in entrepreneurship education coaching programs. This study suggests that the development of entrepreneurial self-efficacy through an online coach-peer conference is important in the development of student businesses.

Originality/value

The findings suggest that nurturing the role of online coach-peer conferences in building student entrepreneurial self-efficacy, both during the pandemic of COVID-19 and in the future.

Abstract

Purpose

Considering that when endorsing the same product, virtual influencers with different identity types (self-created, collaborative) can have different impacts on consumers' purchasing behaviors, this paper aims to explore how to maximize the impact effects of the VIs' respective identities. It provides companies with new perspectives on endorsement strategies.

Design/methodology/approach

The interaction between VI identity type and post type (informational, storytelling) on purchase intention was analyzed in four experiments (N = 1,007), considering informational and normative social influence as intermediate mechanisms and consumer self-construal as moderators.

Findings

The findings show that self-created VI is suited to informational posts and collaborative VI to storytelling posts. This identity-content match effectively triggers the social influence mechanism: informational posts of self-created VI significantly enhance informational social influence. In contrast, storytelling posts of collaborative VI primarily stimulate normative social influence. Consumer self-construal also moderates the process of influencing mechanisms.

Originality/value

Based on social influence theory and matching theory, this paper confirms the existence of an interaction between VI identity types, which influences consumers' purchase intention through informational and normative social influence. This finding fills the research gap in the field of VI endorsement strategy. It also emphasizes the importance of consumer self-construal and contributes new insights into the related field.
