Abstract

Purpose

There is an urge worldwide that school leaders’ mental health and well-being must be prioritised within the education recovery at the local, national and global policy levels. This research identified the intentional well-being practices that school leaders cultivated as they faced unprecedented challenges during the COVID-19 pandemic.

Design/methodology/approach

Data was collected through one-to-one in-depth semi-structured interviews with ten senior school leaders from primary and secondary schools in England. During the pandemic, online interviews were organised using Zoom. An inductive followed by deductive approach qualitative data analysis was employed to offer insights into the multidimensional and sensitive nature of school leaders’ well-being.

Findings

The findings indicated that despite a reported decline in well-being, the participants intentionally engaged in well-being cultivation practices which were both relational: developing multi-faceted support networks, and individual: developing self-care and self-regulation skills. These practices provided different psychological and practical needs necessary for maintaining their well-being and work functioning facing the pandemic.

Originality/value

This study affirms school leaders’ well-being cultivation is an intentional and effortful process involving relational and individual practices to support their multidimensional well-being during extreme challenges. These practices can be mindfully and strategically cultivated. This study enhances the theoretical understanding of school leader well-being and offers timely insights into well-being initiatives in leadership development programmes for educational leaders and policymakers amid global challenges.

Abstract

This study aims to deal with the valuation and accounting of complex derivative instruments. This study attempts to propose a convergence plan by presenting a pricing (fair value evaluation) alternative that considers the accounting process. In this paper, we choose a ZCCB as a representative structured derivative and conduct a case study.

Regarding the expected maturity of ZCCB, there is a need to adjust the historical expected maturity by reflecting the implied expected maturity. As a result of simulation and empirical analysis, it can be seen that the greatest feature of the expected maturity distribution is the Bi-Modal distribution redeemed immediately after the non-call period or at the maturity of the ZCB. Therefore, when using expected maturity, it would be more meaningful to use ZCB maturity date or just after non-call period date rather than the average.

Regarding whether ZCCB's SPPI test is satisfied, the ZCCB return rate is determined according to market input variables and bond issuance conditions and is already fixed at issuance, so it can be judged that the SPPI condition is satisfied.

Abstract

In the paper, the effects of sidecar on the Korean stock market are considered. Throughout the study, we could reach the following conclusions. Firstly, the analysis of return dynamics illustrates that there are no price reversals for all sample groups but price continuations after the event. Secondly, the analysis of volatility and liquidity shows that there are some differences in the effects of sidecar on market volatility and liquidity according to the sample periods‘ however, in the post period of widening of the sidecar trigger levels, the mechanism couldn’t play any role of stabilizing the market volatility and resolving the increased order imbalance around the event. From these results, we could infer that sidecar delays the normal price discovery process and undermine the market liquidity. Also, we suggest that the increased market efficiency of Korea stock market after the financial crisis in 1997, especially deregulation in securities markets, can be a good additional factor for explaining the diffrences in the role of sidecar between sample periods.

Abstract

In this study, we would be interested in knowing how commercial banks use derivatives and analyze its effect on the firm vale in Korea. We find that the derivatives transaction by banks increases during the analysis period and that banks use the derivatives mostly for speculation rather than hedging. Foreign exchange risk is mostly concerned for the purpose of risk hedging, and forward and/or futures are preferred to other derivatives such as option or swap. We also find that the usage of derivatives has a positive effect on the firm value of Korean commercial banks.

Abstract

In this paper we analyze the incentives of derivatives usage and its effect on the risk management and value of firms in Korea. We find that Korean non-financial firms use derivatives not only by the economic incentives to hedge risks but also by the irrational incentives such as the profitability of derivative usage in the previous year. Further results show that the usage of derivatives has a negative effect on the risk management of the firm, which results in the decrease of the firm value. These results show that investors have doubt about the incentives and the effects of derivatives usage in Korea.

Abstract

We illustrate empirically the use of return-based style analysis for domestic stock funds. We search the optimal style model according to the tracking errors, investigate the consistency of the fund style for the optimally selected model, and finally investigate the relationship between fund styles and their fund performance. We use weekly fund return data of domestic stock funds from January 2, 2002 to June 30, 2008, and do style analyses based on the various style indices. The major findings are as follows.

Firstly, we find that the style index models with constraint which in practice restricts short sale are better than those with no such constraint. Secondly, we find that the style index model which divides stock market with four categorized indices based on the dimension of size and book-to market and includes the bond market index is the most useful if they are evaluated based on the out-of-sample tracking errors. While adding the Fama-French 3 factors to the selected model does not improve the explanation power, adding the industry sector indexes improves the explanation power. Thirdly, we investigate the consistency of the fund style models and find that the better performing funds are more volatile in the change of the fund style. Fourthly, we find that, contrary to the expectation that the growth-oriented funds perform better than the value-oriented one, the fund performance and style are observed to be mixed. This finding shows that the fund styles are frequently changed according to their performances and market conditions.

Abstract

This paper investigates a retrospective on the Journal of Derivatives and Quantitative Studies (JDQS) on its 30th anniversary based on bibliometric. JDQSs yearly publications, citations, impact factors, and centrality indices grew up in early 2010s, and diminished in 2020. Keyword network analysis reveals the JDQS's main keywords including behavioral finance, implied volatility, information asymmetry, price discovery, KOSPI200 futures, volatility, and KOSPI200 options. Citations of JDQS articles are mainly driven by article age, demeaned age squared, conference, nonacademic authors and language. In comparison between number of views and downloads for JDQS articles, we find that recent changes in publisher and editorial and publishing policies have increased visibility of JDQS.

Abstract

Purpose

Container shipping companies face various risks with different consequences that are required to be mitigated. Limited empirical research has been done on identifying and evaluating risk management strategies in shipping operations with different risk consequences. This paper aims to identify the appropriate risk mitigation strategies and evaluate the relative importance of these strategies.

Design/methodology/approach

Literature review and interviews were used to identify and validate the appropriate risk mitigation strategies in container shipping operations. A questionnaire with a Likert five-point scale was then conducted to rank the identified risk mitigation strategies in terms of their overall effectiveness. Top six important strategies were selected to evaluate their relative importance under three risk consequences (i.e. financial, reputation and safety and security incident related loss) through using another questionnaire with paired-comparison. Fuzzy analytic hierarchy process (AHP) was then conducted to analyse the paired-comparison questionnaire.

Findings

After conducting a systematic literature review and interviews, 18 mitigation strategies were identified. The results from the first questionnaire show that among the 18 strategies, the top three are “form alliances with other shipping companies”, “use more advanced infrastructures (hardware and software)” and “choose partners very carefully”. After conducting fuzzy AHP, the results show that shipping companies emphasize more on reducing the risk consequence of financial loss; and “form alliance with other shipping companies” is the most important risk mitigation strategy.

Originality/value

This paper evaluates the risk mitigation strategies against three risk consequences. Managers can benefit from the systematic identification of mitigation strategies, which shipping companies can consider for adoption to reduce the operational risk impact.

Abstract

Purpose

This study synthesises the self-determination theory (SDT), expectation-confirmation model (ECM), and protection motivation theory (PMT) to formulate an integrated theoretical framework that elucidates the process of shaping the intention to continue using facial recognition payment (FRP) under the conditional impact of perceived technology security.

Design/methodology/approach

Data from 667 Beijing Winter Olympics visitors with FRP experience were collected through an online survey and analysed using variance based-structural equation modelling (VB-SEM).

Findings

This study reveals that the intention to continue using FRP evolves through three key stages. Initially, in the expectation stage, the multidimensional concept of artificial autonomy (sensing, thought, and action), which is underpinned by self-determination, is pivotal, strongly influencing perceptions of service enhancement and fostering trust in FRP. Subsequently, the confirmation stage underscores the importance of perceived service enhancement and trust as vital drivers in maintaining FRP usage, while also contributing to subjective well-being. Crucially, perceived technology security emerges as a key moderating factor, enhancing positive perceptions and intentions towards FRP, thus influencing its sustained adoption.

Originality/value

This study stands out by revealing the nuanced interplay between artificial autonomy and user perceptions, particularly concerning service enhancement, technology security, and trust, as they influence well-being and the continued adoption of FRP. Robustly grounded in the integrated theoretical framework of SDT, ECM, and PMT, the study’s findings are critical for comprehending the core elements and specific drivers that promote sustained FRP use, especially as we consider its potential widespread implementation. Therefore, this study not only advances theoretical understanding but also offers practical guidance for optimising FRP deployment strategies in a rapidly evolving technological landscape.

Abstract

Purpose

Various employee engagement strategies are proposed to boost organisational performance and business prosperity. Interestingly scholars criticise that these strategies may not always work and mixed views are proposed, leaving a glaring knowledge gap. Drawing on the theories of high-performance-work-practices (HPWPs), this paper aims to conduct a qualitative study, aiming to explore how strategies affect employee engagement and analyse the underlying mechanism.

Design/methodology/approach

This paper gathers research data by interviewing five managers and 15 employees in the hospitality sector. It analyses data through thematic analysis and adopts “Abilities Motivation Opportunities” (AMO) model in improving the analytic rigour. Ethical practices are arranged throughout the project, including consent form, anonymity in participation, confidentiality in responses, freedom to withdraw and data protection.

Findings

Research findings have advanced employee engagement literatures in two ways. On the one hand, when managers recognise employees’ job ability and effort, employees support engagement strategies. On the other hand, however, if managers do not appreciate employees’ job ability and effort, engagement strategies may not necessarily work.

Practical implications

This paper suggests managers display a positive attitude towards subordinates, such as appreciating subordinates’ effort and showing trust and support, if they wish their engagement strategies maximise to the full potential, particularly when managers’ trust is perceived important by employees. Maintaining a healthy communication channel between managers and subordinates also benefits the employee engagement, working morale and overall performance.

Originality/value

To the best of the authors’ knowledge, the current research is the first in its kind, examining hotel employee engagement practice and its implications on performance management in the sector of Nigeria hospitality. Unlike prior studies which link HPWPs to performance directly, our research findings have clarified how HPWPs affect performance through the underlying factors. These are employee engagement and managers’ attitude towards employees.
