Abstract
This study explores the arbitrage profitability of the KOSPI200 futures spread, using intraday data during 10 days prior to the expiration day of each contract for the 9/3/2001 ∼ 6/912005 period. The theoretical frameworks for arbitrage strategies were developed for the analysis. Our results show that 97.36% of the total 8.633 observations were fairly priced. 1.46% (126 observations) were underpriced, and 1.18% (102 observations) were overpriced, in the ex post arbitrage profitability analysis between the futures spread and the calendar spread. Also, in the arbitrage profitability analysis based on the mispricing of the KOSPI200 futures spread against the theoretical price. 90.39% of the total 10.054 observations were fairly priced and 9.61 % (966 observations) were underpriced. There was no overpriced observation. The ajority of those underpriced observations were concentrated in the 3rd Quarter of 2001 and the 1st quarter of 2003. Overall, there were very few arbitrage opportunities except for the introductory period and some contracts with high uncertainty, implying that the KOSPI200 futures spread market has been generally efficient.

Abstract
Purpose
Drawing on the social learning theory, the purpose of this paper is to examine the antecedents and consequences of users’ excessive online social gaming. Specifically, the authors develop a model to propose that observational learning and reinforcement learning mechanisms together determine excessive online social gaming, which further foster adverse consequences.
Design/methodology/approach
The model is empirically validated by a longitudinal survey among users of a popular online social game: Arena of Valor. The empirical data are analyzed using component-based structural equation modeling approach.
Findings
The empirical results offer two key findings. First, excessive online social gaming is determined by observational learning factors, i.e. social frequency and social norm, and reinforcement learning factors, i.e. perceived enjoyment and perceived escapism. Second, excessive online social gaming leads to three categories of adverse consequences: technology-family conflict, technology-work conflict and technology-person conflict. Meanwhile, technology-family conflict and technology-work conflict further foster technology-person conflict.
Originality/value
This study contributes to the literature by developing a nomological framework of excessive online social gaming and by extending the social learning theory to excessive technology use.

Abstract
Purpose
Considering the rapid adoption of social media among consumers and organizations, this study intends to examine the impact of online bundle promotions and contextual interactions on impulse buying as consumers encounter them synchronously. Hence, a research model is proposed with the integration of perceived transaction value, perceived acquisition values, top reviews information, impulse buying tendency and emotional intelligence following the stimulus-organism-response framework, promotional framing effect, and theory of selective attention.
Design/methodology/approach
Data were collected from the active social media members of organization pages and selling groups by utilizing the self-administered questionnaire. This study employed the partial least squares structural equation modeling to evaluate the data of 358 individuals.
Findings
Results reveal the positive impact of targeted constructs on the urge to buy impulsively with complementary partial mediation of impulse buying tendency. Besides, emotional intelligence dissuades users' impulse buying tendencies, but unexpectedly, its moderating effect is insignificant. Further, importance-performance map analysis highlights the highest importance of impulse buying tendency and better performance of perceived transaction value for the urge to buy impulsively.
Originality/value
This research is one of the early studies to explore the influence of social media advertising and contextual social factors (e.g. bundle offers and top reviews information) on impulse buying with the moderation of emotional intelligence and mediation of impulse buying tendency. This research is imperative for scholars and managers with pertinent suggestions to arouse impulse buying.

Abstract
Although Korean sociology of sport is relatively unknown to the international community of scholars, it is a mature field in Korea. Sociology of sport was first introduced in Korea in the mid-1960s when the field first evolved in North America and Europe. However, the development of the field shows different aspects from its Western counterpart due to unique cultural and environmental factors both in academia and in society. There are three major research trends that form Korean sociology of sport. First, there is the research focus on the benefit of sport and physical activity by examining empirical data using quantitative methodologies. The second group of researchers pays attention to individual experience in diverse sport fields and utilize qualitative methodologies to investigate empirical or secondary data. The third and most recent trend is a critical approach that theoretically analyzes ideologies, power relations, and identity politics in sport and society. When looking at the future, there are problems and limitations within the field in Korea. These include lack of continuity in terms of conference sub-themes, over-production of doctoral degree graduates, conservatism rooted in the field, and a danger of regarding sport policy research as an exit for sport sociologists. However, there are also possibilities and reasons for optimism. The biggest possibility for Korean sociology of sport is globalization of the field. Another significant possibility is the need for sport sociologists in planning, developing, and evaluating sport policy. Finally, diversification of the field gives ample opportunities for future research.

Abstract
Maintaining relationships may be difficult in conflict because strong influence attempts can communicate disrespect, especially among Chinese people. The theory of cooperation and competition was used to investigate the effects of persuasion and control influence attempts and social context in conflict. Results from an experimental study support the reasoning that persuasion communicates respect and develops a cooperative relationship. In contrast, coercion communicates disrespect, develops competitive relationships, and results in rejection of the opposing view and negotiator. Consistent with North American research, cooperative compared to competitive context was found to lead to more openness toward the opposing position and negotiator. These results were interpreted as suggesting that persuasion, communication of respect, and a cooperative context facilitate productive conflict management between Chinese people.

Abstract
Because of their relationship‐oriented values, avoiding conflict is thought to be particularly prevalent and appropriate in collectivist societies like China Although research in the West has assumed that avoiding conflict is one approach and a largely ineffective one, collectivists may use conflict avoidance in different ways, including protecting the other protagonist. Eighty‐five managers and employees in six State Owned Enterprises in South China described concrete incidents when they avoided conflict and responded to specific items to measure the prior relationship, motivation, strategies, and consequences. Results identify major motivations and strategies used in conflict avoidance. Findings indicate that Chinese managers and employees relied upon the other person, promoted task productivity, and strengthened the relationship when they had a prior strong relationship and cooperative goals. Cooperative goals and fear of revenge were both found to underlie outflanking (trying to work around the other). Results were interpreted as indicating that avoiding conflict can be useful and even reaffirm an already effective relationship, but like open conflict, it must be managed constructively.

Abstract
In smart cities striving for innovation, development, and prosperity, hydrogen offers a promising path for decarbonization. However, its effective integration into the evolving energy landscape requires understanding regional intricacies and identifying areas for improvement. This chapter examines hydrogen transport from production to utilization, evaluating technologies’ pros, cons, and process equations and using Analytic Hierarchy Process (AHP) as a Multi-Criteria Decision-Making (MCDM) tool to assess these technologies based on multiple criteria. It also explores barriers and opportunities in hydrogen transport within the 21st-century energy transition, providing insights for overcoming challenges. Evaluation criteria for hydrogen transport technologies were ranked by relative importance, with energy efficiency topping the list, followed by energy density, infrastructure requirements, cost, range, and flexibility. Safety, technological maturity, scalability, and compatibility with existing infrastructure received lower weights. Hydrogen transport technologies were categorized into three performance levels: low, medium, and high. Hydrogen tube trailers ranked lowest, while chemical hydrides, hydrail, liquid organic hydrogen carriers, hydrogen pipelines, and hydrogen blending exhibited moderate performance. Compressed hydrogen gas, liquid hydrogen, ammonia carriers, and hydrogen fueling stations demonstrated the highest performance. The proposed framework is crucial for next-gen smart cities, cutting emissions, boosting growth, and speeding up development with a strong hydrogen infrastructure. This makes the region a sustainable tech leader, improving air quality and well-being. Aligned with Gulf Region goals, it is key for smart cities. Policymakers, industries, and researchers can use these insights to overcome barriers and seize hydrogen transport tech opportunities.

Abstract
Purpose
Scholars and professionals are interested in studying customer value in fast-food restaurants. Previous research on the customer value of fast-food restaurants mainly measured the dimensions and relationships of the customer value. However, the research has not examined a method for identifying sources of customer value in fast-food restaurants. Therefore, this study used customer orientation to find customer needs and generate customer value in fast-food restaurants.
Design/methodology/approach
This study presents a conceptual framework with six constructs. A questionnaire was used to gather empirical data from fast-food restaurant customers in Greater Cairo, Egypt. The suggested framework was evaluated using confirmatory factor analysis, reliability and validity analysis, standardized path coefficients and regression-based moderation analysis.
Findings
This study found that proactive customer orientation has a substantial direct and positive impact on customer perceived value. Customer perceived value is also positively influenced by responsive and proactive customer orientations, with customer desired value change intensity acting as a moderator. Customer perceived value substantially impacts customer satisfaction, and the latter substantially affects behavioural intention.
Practical implications
This study offers several suggestions for managers of fast-food restaurants on how to employ customer orientation to find current, latent and future customer desires to provide customer value.
Originality/value
This is the first research in the hospitality industry to demonstrate how responsive and proactive customer orientation may be used to recognize customer needs and provide the desired customer value.

Abstract
Purpose
This study aims to explore the strategic impact of R&D and export activity on the diverse dimensions of US manufacturing firms’ performance. It also explores, using a predictive analytic model, the interactive synergistic effect that R&D and exports have on firm performance.
Design/methodology/approach
This study presents an innovative two-stage regression-neural network approach. Complementing conventional statistical analysis, the predictive backpropagation neural network explores the relative impact of R&D and exports and their synergistic effect on firm performance.
Findings
This study demonstrates the significant and positive effect of R&D and export strategy/activity on the economic performance of leading US manufacturing firms, particularly on their market-based performance (i.e. sustained growth rate or SGR). Furthermore, this study finds that the synergistic effect of R&D and exports on short-term performance (i.e. return on investment) is positive in high-tech firms but negative in low-tech firms. However, the synergistic effect on SGR is increasingly positive regardless of the level of technology.
Originality/value
In addition to traditional statistical analysis, this study uniquely investigates the relative importance of selected strategic variables, along with R&D and export activity and their differential synergistic effects, for firms’ economic performance in contrasting industry settings (high-tech vs low-tech).
