The purpose of this paper is to improve the air movement operations planning heuristic in the literature to generate better solutions in a shorter time period.

Through a rigorous design of experiments (DOEs), we make significant heuristic improvements by evaluating alternative modular methodologies and tuning heuristic parameters for two scenarios. This includes a new approach to considering refueling operations.

We find the fine-tuned heuristic averages a 33% objective improvement and 70% reduction in computation time over the heuristic with original parameters for one of the scenarios. Additionally, we analyze the heuristic's quality of solution over time.

Further analysis is required to generalize heuristic settings, which would require significant access to operational data or a portfolio of scenarios of interest.

Tuned heuristic parameters reduce the computation time from hours to minutes. This also makes it practically feasible to adjust parameters in the objective function to generate multiple courses of action (COAs) for a given instance.

This research provides novel vehicle assignment and routing heuristic improvement alternatives and demonstrates a DOEs-based heuristic tuning procedure.

Craft breweries have a growing role in the beer tourism niche as a place-based attraction but also in daily life as a community space. Research has examined how such breweries can appeal to both tourist and local markets through neolocalism in the form of place branding and local embeddedness. This paper aims to consider the extent to which breweries communicate neolocal themes in visual social media marketing through Instagram images.

This research examines 3,299 Instagram images posted on the official accounts of 13 Houston, Texas (USA) microbreweries and taproom breweries over the course of 2022. Content-semiotic analysis identifies key themes in these images and explores the extent to which breweries signify neolocal themes through these images.

Manifest image content generally appeals to interests in consuming beer and communicates logistical information about if, and when, to visit the brewery. Elements in Instagram images have the potential to convey meanings about neolocalism in the craft beer product, branding, local embeddedness and place-based experiences but such strategies have not been extensively developed or used.

Although both academic and industry sources recognize the importance of social media and visual content in connecting with potential consumers, to the best of the author’s knowledge, this study is the first to examine the extent to which breweries employ neolocal strategies through social media marketing.

This practice forum paper aims to present a theoretical framework to better develop the required supply chain management (SCM) competencies and the workforce needed for managing public health supply chains.

This framework is driven by iterative systems thinking, a deeper consideration of the SCM labor market and a comprehensive mapping of human resource system requirements. The framework centers around three tools. A labor market analysis assesses factors influencing supply of and demand for health SCM workers in a country context. To improve supply of and demand for workers, the SCM Professionalisation Framework provides reference documents to establish health SCM as a recognized profession. The human resources for SCM Theory of Change explains and assesses the conditions required to achieve optimal workforce performance at the organizational level. The Ministry of Health in Rwanda applied these three tools sequentially to assess and improve the supply and performance of its health SCM workforce.

The authors describe this framework, how the tools were applied in Rwanda, and early impressions of the results.

Practitioners can apply this approach to improve SCM competence and promote the attractiveness of health SCM positions by formalizing their professional status. This could lead to a pool of individuals who seek SCM qualifications and, in time, overcome the current shortage of health SCM workers. Employers can apply this approach to structured roles and workforce needs to meet health SCM system requirements. This would lead to a greater demand for and use of appropriately trained personnel.

This paper presents a novel, iterative, systems-thinking approach to develop human resources in public health supply chains. Rwanda is the first country to apply all three tools using this framework.

This study aims to comprehensively understand the regulatory landscape and digital transformation (DT) within the banking sector, anchored in the theory of national innovation systems.

Using insights from a comprehensive literature review, an innovative framework is introduced to categorize regulators and digital banking attributes across 88 countries. The study uses k-means clustering to analyze the digital banking and regulatory status of 88 countries, tracing their evolution over two distinct timeframes.

The cross-country analysis spanning 2014 and 2022 reveals compelling trends in regulatory rankings and digital banking across diverse nations. These findings shed light on the dynamic interplay between regulatory environments and technological innovation.

This research contributes to knowledge by establishing a robust framework for understanding regulator dynamics in digital banking across a wide spectrum of countries. It offers valuable insights for academia, practitioners and policymakers by elucidating the complex relationship between the regulatory landscape and DT, shaping discourse and implications in this field, and informing strategic decision-making and policy formulation in the global financial landscape.

The current landscape of management scholarship faces criticism for prioritising theoretical development over practical relevance, leading to a disconnect between academic research and industry practices or applications. By exploring Pavitt’s work, the authors aim to highlight the importance of contextual understanding in innovation processes and to advocate for recognising diverse scholarly contributions that challenge established norms. A pragmatic theorist and mentor to a whole generation of innovation science and policy scholars worldwide, especially in Europe, Keith Pavitt left a legacy that is insufficiently acknowledged. Ultimately, this paper seeks to bridge the gap between theory and practice and to defend an innovation management that is responsive to contemporary organisational challenges.

The authors review the most relevant works by Keith Pavitt as a practitioner and as a “pragmatic theorist” and his network of author relationships, including all papers, special issues and reports published after his passing. Then, the authors discuss how those seminal papers or reports have been used and could be used in the future. This paper argues for a balanced approach that integrates rigorous academic inquiry with practical insights, emphasising the contributions of Keith Pavitt as a pioneering figure in Innovation-as-Practice.

The authors highlight that much of the current understanding of science and policy of innovation can be traced back to Pavitt’s work and that many future debates about technology could be enhanced by considering his findings. He has the stature of a parental figure, and his taxonomy, based on practice and empirical data, much like other management analysis tools, is widely used but not widely recognised yet, especially by industry managers or employees.

This paper sheds new light on an unacknowledged transdisciplinary pioneer, whose work is situated at the intersection of theory and praxis in Innovation Management: Keith Pavitt. It also advocates for a more transdisciplinary and circumstantial historical approach to management scholars.

While work-life policies (WLPs) are tools that employees may draw on to better manage and balance their work and life demands, there is growing evidence that suggests the usage of WLPs may negatively impact other employees. Drawing from the theory of role dynamics and social role theory, we examine the indirect effect of co-workers taking childcare leave (CTCL) on work anxiety via work-role overload, as well as the impact of gender on this indirect relationship.

We used Prolific Academic to recruit 236 employees to participate in a three-wave study. These data were analyzed as a hypothesized structural equation modelling (SEM) using SPSS AMOS.

Findings reveal: (1) CTCL positively relates to work anxiety via work-role overload, and (2) gender moderates this indirect effect such that this positive relationship is stronger for men than women.

Work-life policy makers should take note of the “hidden costs” associated with work-life policy usage on other employees. Managers should work with policy users to mitigate the negative effects of policy usage on others.

In contrast to broader WLP research, which focuses on the benefits of policy usage on the policy user, this research shows the negative implications of work-life policies on others’ work anxiety via work-role overload. In doing so, it becomes the first study to showcase a crossover effect of CTCL on employees’ work anxiety.

This study aims to present a sustainability framework that advances the conceptual understanding of the role of spirituality in the context of social entrepreneurship.

Through a systematic literature review of spirituality at both the individual and organisational levels, the triple bottom line framework of sustainability, and business ethics, this study offers a sustainability framework for social entrepreneurship. It explains how spirituality at these levels influences various dimensions of social entrepreneurship and helps achieve social, economic, environmental and ethical outcomes.

The study proposed that individuals with spiritual practices are more likely to engage in entrepreneurial, social, ethical and environmental orientations, while organisations with spiritual practices are more likely to engage in employee, market and ethical orientations. Spiritual capability can serve as a strategic advantage and contribute to the sustainable development of social enterprises.

This study makes three significant contributions. First, it presents an emergent framework for integrating spirituality (at both individual and organisational levels) and sustainability within the social entrepreneurship literature, offering implications for both social entrepreneurs and social enterprises. Second, this study proposes incorporating ethics as the fourth dimension of sustainability and argues that spirituality can act as a catalyst for achieving sustainability in social entrepreneurship. Third, this study identifies seven critical dimensions of social entrepreneurship: spiritual capabilities, entrepreneurial orientation, social orientation, environmental orientation, market orientation, ethical orientation and employee orientation, all of which contribute to ethical and sustainable development.

Over the last decades, the need for sustainable energy production and consumption has been heavily discussed. However, there has been no consensus in the extant literature. Thus, to this end, this study aims to explore the long-run and causality connection among disaggregated energy consumption, environmental tax and economic growth in a carbon-function framework for Turkey.

This study uses annual frequency data for econometrics analysis. To this end, our analysis utilizes the autoregressive distributive lag (ARDL) technique for cointegration and long-run analysis, while the Granger causality was used for causality direction.

Economic growth drives Turkey’s Load Capacity Factor (LCF), indicating energy efficiency is linked to economic performance. Renewable energy boosts LCF, while nonrenewable energy hinders it. Population growth positively affects energy efficiency, but environmental taxes have minimal impact, suggesting policy reform is needed. These outcomes have far-reaching implications for macroeconomic policies and environmental sustainability in Turkish economy energy mix amidst its growth path.

The findings suggest the need for policy reforms prioritizing renewable energy investments to enhance Turkey’s energy efficiency and sustainability. Additionally, the current environmental tax structure requires reevaluation to support sustainable energy practices better. These policy changes are crucial for balancing Turkey’s economic growth with environmental goals, ensuring a more sustainable energy future.

This study explores the role of government policy in form of environmental tax in environmental performance in Turkey.

Quality management (QM) plays a pivotal role in driving organisational efforts to enhance operational efficiency and customer satisfaction. This study aims to explore the most important themes in QM over the past three decades, identifying and analysing the top ten key themes that have shaped the field during this period. This study, involving leading academics and industry practitioners, lays the groundwork for a three-to-four-year exploration of the most influential QM themes worldwide.

The authors conducted a comprehensive review of QM literature over the last three decades from top specialist journals on QM. This is followed by conducting a global pilot survey with leading academics and practitioners to pinpoint the top ten dominant themes of QM for organisations to leverage in gaining and maintaining a competitive edge.

The top ten themes of QM, as identified by authors through input from academics and practitioners worldwide, offer valuable insights for companies of all sizes and sectors. These themes serve as a guide for the successful and sustainable implementation of QM practices and continuous improvement strategies.

Despite a limited sample size, the initial findings provide a glimpse into critical themes. Over the next three years, as the study progresses, we anticipate potential changes in the results. Notably, the comparison of themes between manufacturing and services as well as large and small enterprises, remains unexplored in the current investigation.

The authors of this study assert that their research will pave the way for future themes in the digitalization era. Moreover, this research stands out as one of the most exhaustive examinations from both academic and practitioner viewpoints, offering a unique perspective not commonly found in existing literature.

In this research, arbitrage opportunity is tested between the yield rates computed by the NSS model, and the computed forward rates between conventional and Islamic finance to see any arbitrage opportunity. The research questions are the conventional and Islamic finance yields at the same level and equal to each other to avoid arbitrage? Whether conventional and Islamic forward rates differ significantly and thus create any arbitrage opportunity. This study aims to find the presence or absence of arbitrage between conventional and Islamic finance yield rates.

The NSS model is the latest model in calculating yield and forward rates. In the method the error level is minimized so expected yield rate and given yield rate both converged (Vahidin and Anastasios, 2020). When they converged it gives the researchers all six months’ yield rates. For the Nelson Siegal method, all the six months’ yield rates are available and these yield rates can be used to compute the forward rates.

The authors concluded there is a significant difference between the conventional yield rate and the Islamic yield rate. It suggests that because there are significant differences, its suggest arbitrage is possible. So anyone interested in making a guaranteed profit. The conventional yield rates are lower; hence, anyone can borrow from the conventional finance system and invest the money in the Islamic financial system because investments are getting higher rates of income in the form of yield rate in Islamic Finance. So, one can make money because of this difference. Statistically, it is possible to make money, but practically, the authors observed the difference, however it is very meager. The arbitrage opportunity between Islamic finance and conventional finance will not affect the economy because the significant difference is too small. The disturbance in the arbitrage opportunity due to the values is very meager and insignificant.

This research does not address the derivative contracts’ role in risk management; future researchers could take up this as another research.

This research will be beneficial for financial institutions, especially institutional investors. Besides, this research will help the regulators and investment bankers in assisting where and future losses especially bond portfolios in conventional finance and Islamic finance. This study will also contribute and help the asset manager of mutual funds in the mutual fund industries.

In effect, this research will strengthen the financial system, capital market and bond market, derivative contracts such as options contracts, futures contracts, swap contracts and forward contracts will use computed forward rates for assessing future losses (value at risk [VaR]) and to hedge them (Balakrishnan, 2020).

As this topic is rarely studied it will increase the literature present in this domain.
