Abstract
This study examines the impacts of the KTB futures options, newly introduced at the Korea Futures Exchange (KOFEX) on May, 2002, on the intraday volatility and liquidity of the KTB futures markets for the period from January 17, 2002, to August 30, 2002. The results show that the volatility of the KTB futures appears to have increased since the inception of the KTB futures options. However, the increase in volatility largely disappears after controlling for the effects of volume, time-to-maturity, day-of-the-week, and bid-ask bounce. There is some mixed evidence regarding the impact on the liquidity of the KTB futures markets, in the sense that the trading volume has increased significantly whereas the bid-ask spreads have widened too. The KTB futures price changes are more likely to lead the price changes of the KTB futures options by about 15 minutes, which is probably due to the infrequent trading problem on the part of the KTB futures options. Finally, though infrequently traded, the put-futures parity condition is rarely violated, and thus is difficult to be exploited for arbitrage transactions, indicating that the two markets are closely linked each other.

Abstract
Purpose
This study aims to identify different antecedents and reveal divergent moderating effects of horizontal collectivism, thereby unlocking the asymmetric mechanisms for employees’ brand citizenship behavior (BCB) and negative word-of-mouth (NWOM).
Design/methodology/approach
This study uses a survey data set and analyzes it with structural equation modeling along with common latent factor analysis designed to control for common method variance.
Findings
BCB is associated with pride at work but not perceived organizational support (POS), so POS drives BCB not directly but indirectly through the emotion of pride at work. In contrast, employees’ NWOM is associated with both POS and frustration, and POS drives NWOM directly and indirectly through the emotion of frustration. Horizontal collectivism has divergent moderating effects that strengthen the relationships of BCB with POS and pride at work and weaken the relationship between employees’ NWOM and frustration.
Originality/value
This study makes two major theoretical contributions to internal branding. First, as a response to the need for an investigation into drivers of employees’ brand-oriented behaviors, it will identify different psychological antecedents and mechanisms for BCB and employees’ NWOM. Second, capturing the potential of horizontal collectivism on employees’ brand-oriented behaviors, this study will reveal the potential divergent moderating effects of horizontal collectivism on BCB and employees’ NWOM. These two contributions will lead to a better understanding of the different mechanisms for employees’ BCB and NWOM.

Abstract
Technology-facilitated violence against women (TFVW) is readily becoming a key site of analysis for feminist criminologists. The scholarship in this area has identified online sexual harassment, contact-based harassment, image-based abuse, and gender-based cyberhate – among others – as key manifestations of TFVW. It has also unpacked the legal strategies available to women seeking formal justice outcomes. However, much of the existing empirical scholarship has been produced within countries like the United States, United Kingdom, and Australia, and there has been limited research on this phenomenon within South East Asia. As such, this chapter maps how technology is shaping Singaporean women's experiences of gendered, sexual, and domestic violence. To do so, it draws upon findings from a research project which examined TFVW in Singapore by utilizing semistructured interviews with frontline workers in the fields of domestic and sexual violence and LGBT services. Drawing from Dragiewicz et al.’s (2018) work on technology-facilitated coercive control (TFCC), I argue that victims-survivors of dating, domestic, and family violence need to be provided with support that is TFCC informed and technically guided. I also suggest that further research is needed to fully understand the prevalence and nature of TFVW in the Singaporean context.

Abstract
Violence against women and girls (VAWG) is a global policy issue with significant social, economic and personal consequences. The burden of VAWGs is distributed unequally, with rates of gender violence significantly higher in low- to middle-income countries of the Global South. Yet the bulk of global research on gender violence is based on the experiences of urban communities in high-income English-speaking countries mainly from the Global North. This body of research typically takes the experience of women from Anglophone countries as the norm from which to theorise and frame theories and research of gender-based violence. This chapter problematises theories that the privilege women in the Global North as the empirical referents of ‘everyday violence’ (Carrington et al., 2016). At the same time, however, it is important to resist homogenising the violence experienced by women across diverse societies in the Global South as oppressed subaltern Southern. This binary discourse exaggerates the differences and obfuscates the similarities of VAWG across Northern and Southern borders and reproduces images of women in the Global South as unfortunate victims of ‘other’ cultures (Durham, 2015; Narayan, 1997). This chapter contrasts three examples, the policing of family violence in Indigenous communities in Australia; Image-based Abuse in Singapore; and the policing of gender violence in the Pacific as a way of concretising the argument.

Abstract
This chapter highlights the characteristics of Asia through the analysis of policy-related documents by five donor countries, namely Japan, South Korea, China, India and Thailand. It will also examine the roles played by regional bodies such as the Southeast Asian Ministers of Education Organization (SEAMEO) and ASPBAE (the Asia South Pacific Association for Basic and Adult Education) as the horizontal channels influencing aid policies in respective countries. Together with the analysis of the national and organizational policies, the regional process of building consensus on the post-2015 agenda is examined, with a particular focus on the Asia-Pacific Regional Education Conference (APREC) held in August 2014.
The analysis reveals that the region has two faces: one is imaginary and the other is functional. There is a common trend across Asian donors to refer to their historical ties with regions and countries to which they provide assistance and their traditional notions of education and development. They highlight Asian features in contrast to conventional aid principles and approaches based on the Western value system, either apparently or in a muted manner. In this sense, the imagined community of Asia with common cultural roots is perceived by the policymakers across the board.
At the same time, administratively, the importance of the region as a stage between the national and global levels is recognized increasingly in the multilateral global governance structure. With this broadened participatory structure, as discussed in the chapter ‘Post-EFA Global Discourse: The Process of Shaping the Shared View of the ‘Education Community’’, the expected function of the region to transmit the norms and requests from the global level and to collect and summarize national voices has increased.

Abstract
Application of the numerical method to the art of Medicine was regarded not as a “trivial ingenuity” but “an important stage in its development”; thus proclaimed Professor Bradford Hill, accepted as the father of medical statistics, a study still largely unintelligible to the mass of medical practitioners. The need for Statistics is the elucidation of the effects of multiple causes; this represents the essence of the statistical method and is most commendable. Conclusions reached empirically under statistical scrutiny have mistakes and fallacies exposed. Numerical methods of analysis, the mathematical approach, reveals data relating to factors in an investigation, which might be missed in empirical observation, and by means of a figure states their significance in the whole. A simplified example is the numerical analysis of food poisoning, which alone determines the commonest causative organisms, the commonest food vehicles and the organisms which affect different foods, as well as changes in the pattern, e.g., the rising incidence of S. agona and the increase of turkey (and the occasions on which it is served, such as Christmas parties), as a food poisoning vehicle. The information data enables preventive measures to be taken. The ever‐widening fields of Medicine literally teem with such situations, where complexities are unravelled and the true significance of the many factors are established. Almost every sphere of human activity can be similarly measured. Apart from errors of sampling, problems seem fewer and controversy less with technical methods of analysis then on the presentation and interpretation of figures, or as Bradford Hill states “on the application of common sense and on elementary rules of logic”.

Abstract
Purpose
With the emergence of a variety of communication channels on social media, employees have more opportunities to engage with external stakeholders for or against their organizational brand. In such a context, focusing on negative word-of-mouth (NWOM) as an employee’s negative discretionary brand-oriented behavior, the current study aimed to identify negative emotions that can serve as drivers for NWOM more strongly than for counterproductive workplace behavior (CWB), relying on the discrete emotion perspective. This study also aimed to examine whether employees’ perceived brand knowledge can directly diminish employees’ NWOM and CWB and attenuate the influence of negative emotions.
Design/methodology/approach
A questionnaire was used to gather relevant data, which were analyzed by structural equation modeling.
Findings
The findings showed that anger was more strongly associated with employees’ NWOM than withdrawal and that envy was more strongly associated with CWB toward individuals than employees’ NWOM. Employees’ perceived brand knowledge was negatively associated with both NWOM and CWB directly and mitigated the association of negative emotions such as anger and envy with CWB, but not with NWOM.
Originality/value
Based on the discrete emotion perspective, the current study explored the relative magnitude of emotional antecedents for employees’ NWOM and conventional CWB. Also, it expanded the previous findings on the positive effects of perceived brand knowledge on the positive outcomes of employees’ actions and its mitigating effects on NWOM and CWB.

Abstract
Purpose
Reflecting on the importance of negative word-of-mouth (NWOM) executed by internal audience of brand management, this study aims to explore the mechanism of employees’ NWOM in the emotional exhaustion context.
Design/methodology/approach
Focusing on employees’ active brand-oriented deviances, this study used a surveyed data set (n = 150) collected from negatively aroused employees experiencing a negative event within their organization. Structural equation modeling was adopted to test the hypotheses.
Findings
The current study revealed that employees’ NWOM is associated with emotional exhaustion. Also, it discovered that emotional exhaustion is more strongly associated with employees’ NWOM than turnover intention.
Research limitations/implications
Relying on self-regulation theory, the current study identified emotional exhaustion as a critical antecedent of employees’ NWOM. Future researchers can use the longitudinal research design or temporal separation as an effort to prevent common method variance.
Practical implications
Internal audiences engage in negative brand-oriented performance by spreading NWOM. Further, the advance in social media may instigate NWOM spread by internal audiences to external audiences.
Originality/value
This paper tests the explanatory power of conservation of resources theory and self-regulatory theory in terms of the impact of employees’ emotional exhaustion on NWOM and turnover intention.

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.
