Presents a linear goal programming (LGP) model, which can be used to derive an optimal daily production schedule for JIT production systems. Also provides an explanation of how a detailed post‐optimal LGP analysis can enable a decision maker to examine the effects of production scheduling in a JIT “mixed‐model” production environment. To illustrate the informational efficacy of the proposed JIT‐based LGP model, presents an illustrative example.

This article examines the impact of introducing computer technology in just‐in‐time (JIT) systems. Literature review has generally supported the notion that introducing computers within JIT production systems may enhance productivity. Also, the productivity of a computer integrated manufacturing (CIM) system may be enhanced by integrating it with the just‐in‐time (JIT) production system. This integrated production system is called the computer integrated just‐in‐time (CIJIT) production system. This empirical study provides strong evidence that integration of CIM and JIT can significantly improve a firm′s productivity and competitiveness.

The centralized processes of today’s power trading systems are complex and pose a risk of price tampering and hacking. The decentralized and unmodifiable nature of the blockchain technology that has recently been highlighted offers the potential to improve this power trading process. The purpose of this study is to implement a system to apply the blockchain technology to the problem of power trading.

The authors modeled the power trading problem as the interaction between admin, producer and consumer nodes. And a power trading scenario has been created for this model using a blockchain platform called Multichain which is both fast and highly scalable. To verify this scenario, they implemented a trading system using Savoir, a Python-based JsonRPC module.

Experimental results show that all processes, such as blockchain creation, node connectivity, asset issuance and exchange transactions have been correctly handled according to the scenario.

In this study, the authors have proposed and implemented a power trading method that determines price according to the pure market principle and cannot be manipulated or hacked. It is based on the nature of blockchain technology that is decentralized and cannot be tampered.

The purpose of this paper is to investigate the effects of empowering leadership, directive leadership and initiating structure on innovation in small and medium enterprises (SMEs) and examine the mediating role of climate for innovation on those relationships.

Applying structural equation modeling, the study empirically tested the model on a sample of 330 employees from tourism SMEs in Vietnam.

Results indicated that climate for innovation mediated the relationship between empowering leadership and innovation and also initiating structure and innovation. Whereas empowering leadership was found to have a negative direct influence on innovation, directive leadership was unrelated to innovation.

The results of this study contribute to the literature by expanding the existing research on SME innovation, assessing the effect of diverse leadership styles and a climate for innovation on the innovation performance of SMEs. The findings enrich the literature by indicating the contribution of empowering leadership, directive leadership and initiating structure on encouraging innovation in SMEs.

When leading subordinates in the SME context, leaders who have a clear understanding of the effect of empowerment, direction and initiating structure can optimally seek to stimulate innovation. These leadership approaches influence employees’ task, interpersonal and role-related processes that shape a climate for innovation.

The novelty of this paper is that it examines the differential influences of empowering leadership, directive leadership and initiating structure on innovation and the mediating role of climate for innovation on these relationships.

The aim of this paper is to explore the changes in the ICT and global value chains (GVCs) after the COVID-19 pandemic.

This study compared the difference between Korea’ domestic ICT industries, ICT imports and ICT exports before and after the COVID-19 outbreak by using trade data of ICT products and national economic indicators, and presents growth strategy for the ICT industry in the post-COVID 19 era. For this purpose, this study determined the causalities between Korea's imports/exports of ICT products and composite Indexes before and after COVID-19, and derived implications in the ICT industry environment after the COVID-19 pandemic.

Analysis results showed the following changes in Korea's ICT industry in the post-COVID-19 world. (1) Non-face-to-face and contact-free technologies related sectors in the ICT industry, such as the semiconductor sector, have grown exponentially; (2) as the USA has grown as the new key player, the causal relationship with China, a key player of the GVC in the pre-COVID-19 era, disappeared; and (3) the GVC of the ICT industry is not a rigid one-way vertical structure, but is changing to a flexible structure influenced by cooperation and competition between countries.

The results indicate that it is essential to constantly develop new ICT sectors that make use of non-face-to-face and contact-free technologies in the post-COVID-19 era, and the main strategies in response to the changed GVC would be taking the initiative by securing source technologies and expanding through cooperation with other GVCs and resource sharing.

The present study aims to elucidate the mediating role of relational energy between empowering leadership and its attitudinal (employee engagement), behavioral (knowledge sharing) and performance (task) related outcomes, respectively, and the moderating role of autonomy between empowering leadership and relational energy, using the social cognitive theory.

The study used surveys in the small and medium-sized enterprises sector and collected time-lagged data to address common method variance and reveal causal relationships. AMOS was used to conduct hypothesis testing.

The results suggest that empowering leaders have a positive impact on outcomes such as employee engagement, knowledge sharing and task performance, and this impact is mediated by relational energy. Autonomy moderates the empowering leaders and relational energy relationship, strengthening it when autonomy is high.

Organizations should focus on leadership development programs depending on the need. Empowering leadership should be promoted to get positive attitudinal and behavioral outcomes in terms of employees. Empowering the employee in terms of decision-making helps motivate employees to perform better.

The study contributes to the empowering leadership literature by associating social cognitive theory. Empowering leaders has the potential to increase employee engagement, knowledge sharing and task performance.

During exposure to new cultures, immigrants face numerous life changes and challenges, which negatively affect mental health, yet environmental supports may address these concerns. This study aims to examine how neighborhood quality, acculturation and acculturative stress are associated with immigrants’ mental health.

The sample consisted of 511 Asian immigrants who were born in their country of origin and immigrated to the USA. Path analysis using analysis of moment structures (version 22.0) was conducted to test the hypothesized model.

The results from the path analysis indicated that perceived neighborhood quality and acculturative stress had direct effects on mental health among Asian immigrants. The study also found a significant indirect pathway to mental health where more favorable perceptions of neighborhood quality were associated with higher levels of acculturation and lower levels of acculturative stress, which, in turn, resulted in better mental health.

The results of the study highlight the importance of improving neighborhood quality as a means by which to facilitate cultural adjustment/adaptation to US culture and thus, improve mental health among Asian immigrants. In addition, the authors suggested considering cultural origin in designing health programs and/or policies for Asian immigrants, which could promote mental health among Asian immigrants. Based on the results of the model, this study produced insightful information and suggestions on how to improve Asian immigrants’ mental health more effectively.

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.

The purpose of this paper is to compare the direct and indirect effects of transformational, ethical and empowering leadership (EL) on promotive and prohibitive voice behavior. The study also explores the mediating effects of leader-member exchange (LMX) and moderating effects of individual power distance orientation (IPDO) in the hypothesized model. The research conducted attempts to identify the most suitable leadership style for encouraging promotive and prohibitive voice behavior in service sector organizations in India.

Purposive and snowball sampling was used for data collection. Necessary condition analysis (NCA) was conducted to identify the most suitable style for encouraging promotive and prohibitive voice behavior. The results NCA were later verified using the structural equation modeling technique.

Results of the study displayed the supremacy of EL style in promoting high-quality LMX and “promotive and prohibitive” voice over transformational and ethical leadership in Indian service organizations. Considering the overall results of the study, EL appears to be the most suitable style for encouraging promotive and prohibitive voice in a high power distance country like India.

Self-reported measures utilized in the study might have affected the findings and hence, should be interpreted with caution.

Researchers propose the adoption of EL style for encouraging promotive and prohibitive voice in Indian service sector organizations. The researchers also highlight the noteworthy impact of LMX and IPDO on promotive and prohibitive voice behavior, which makes it a point for the leaders to work toward lowering IPDO amongst followers to promote both promotive and prohibitive voice behavior for the growth of an organization.

The study is the first one to conduct a comparative moderated mediated examination to analyze the effects of transformational, ethical and EL in encouraging promotive and prohibitive voice behavior in Indian organizations.

Aiming to find out how to incorporate green building into the architectural curriculum, this study aims to explore the psychological path for cultivating architectural students’ awareness and motivation to learn the green design concepts and related technologies.

Based on a global review of relevant architectural courses in universities, a set of green building learning behaviors was proposed and a survey was conducted in architectural schools in South China to verify the “value-belief-norm” theory through the lens of green building learning behaviors. The psychological path that affects students’ green building learning behaviors was analyzed using structural equation modeling.

The results showed that biospheric and altruistic values could directly affect students’ motivation to learn green building, while personal norms served as the mediating condition for personal values and beliefs, and ultimately improved motivation.

The study suggests that the cultivation of environmental awareness and a sense of the ecological crisis should be developed through foundation courses, by establishing an ecological architecture curriculum, to more effectively guide students to learn and practice green building.

This study, for the first time, applied the “value-belief-norm” theory, which was developed to explain the psychological path for pro-environmental behaviors, to green building learning behaviors of architectural students.
