Abstract
Purpose
Bayesian cubature (BC) has emerged to be one of most competitive approach for estimating the multi-dimensional integral especially when the integrand is expensive to evaluate, and alternative acquisition functions, such as the Posterior Variance Contribution (PVC) function, have been developed for adaptive experiment design of the integration points. However, those sequential design strategies also prevent BC from being implemented in a parallel scheme. Therefore, this paper aims at developing a parallelized adaptive BC method to further improve the computational efficiency.
Design/methodology/approach
By theoretically examining the multimodal behavior of the PVC function, it is concluded that the multiple local maxima all have important contribution to the integration accuracy as can be selected as design points, providing a practical way for parallelization of the adaptive BC. Inspired by the above finding, four multimodal optimization algorithms, including one newly developed in this work, are then introduced for finding multiple local maxima of the PVC function in one run, and further for parallel implementation of the adaptive BC.
Findings
The superiority of the parallel schemes and the performance of the four multimodal optimization algorithms are then demonstrated and compared with the k-means clustering method by using two numerical benchmarks and two engineering examples.
Originality/value
Multimodal behavior of acquisition function for BC is comprehensively investigated. All the local maxima of the acquisition function contribute to adaptive BC accuracy. Parallelization of adaptive BC is realized with four multimodal optimization methods.

Abstract
The goal of this chapter is to reexamine the nature and structure of the military–industrial complex (MIC) through the works of John Kenneth Galbraith. MIC, or military power as he prefers, is a coalition of vested interests within the state and industry that promoted the military power in the name of “national security” for their interests. Galbraith’s theory of giant corporations helps us understand the role of military corporations in the MIC. Moreover, he is a critical scholar in examining this topic because he was a political insider in the Roosevelt, Kennedy, and Johnson administrations and a prominent public intellectual against the Vietnam War. Against this background, this chapter has three parts. After explaining the development of military Keynesianism with respect to the main economic thoughts, it examines the history of the MIC and its impact on economic priorities during and after the Cold War through Galbraith’s works. Finally, this chapter discusses MIC’s relevancy today and evaluates Galbraith’s prophecies.

Abstract
Purpose
Criminology both as a field of study and as a practice draws on a broad range of disciplines from the social, behavioural, human, natural and medical sciences. However, over recent times, the natural and medical sciences have been dismissed, overlooked and even ridiculed, largely since the rise of critical criminology and related contemporary conflict and social harm approaches from the 1960s onwards. This has led to a chasm emerging between the study of criminology and the practice of criminology such as within a policing context. This paper aims to provide a review of an emerging forensic biological method, that of neuroscience, within a criminological context, to illustrate the importance of criminology embracing and reawakening its natural and medical science roots.
Design/methodology/approach
The paper draws on a conceptual design to realign criminology with the full range of disciplines used to inform its theory and application.
Findings
Through illustrating the role of forensic neuroscience, the paper reawakens the scientific method and inquiry of criminology reflecting the importance of the discipline being, and remaining, multi- and trans-disciplinary in nature. The paper, while reflecting on the limitations of scientific method and inquiry, outlines the strengths this approach to criminology engenders, promoting and delivering a scientific-based research agenda that aims to support industry partners in the prevention, disruption and reduction of crime, disorder and threats to public security.
Practical implications
Firstly, it is important for criminology as a field of study to (re)engage with its scientific method and inquiry. Secondly, criminology, by engaging in robust scientific method and inquiry, has a significant contribution to make to professional practice and the work of industry professionals. Thirdly, while there are limitations to such scientific method and inquiry, it should not lead to this component of criminology being discarded. Fourthly, there is a need for contemporary research in the area of scientific method and inquiry and its application to criminological contexts, including that of police practice. Finally, by engaging in scientific method and inquiry that is evidence based, a chasm between the field of study and the practice associated with criminology can be addressed.
Originality/value
This paper addresses the gap between criminology as a field of study and as a practice by reengaging with scientific method and inquiry, illustrating the need and value of criminology being and remaining multi- and trans-disciplinary, ensuring professions underpinned by criminology are supported in their practice.

Abstract
A pandemic causes abrupt and unanticipated disruptions in many facets of society. A lot of authorities have quickly turned to online teaching methods. The best methods for online teaching have become a hot topic of discussion due to this urgent fast transmission. It was difficult to teach physiology to medical and paramedical students online because of concerns about how to give the students an effective interactive online teaching practice and how to guarantee successful outcomes. Therefore, three approaches have been individually applied to medical and nursing students for the first time in the physiology department of the Faculty of Medicine in Rabigh, King Abdulaziz University. Through online lectures and assignments, the strategies attempted to capture the students’ interest and interaction. The second-year nursing students were given a mind map project to complete after the lecture. The third-year medical students used a crossword puzzle game to test the students’ understanding. The third-year medical students were presented with short stories to better comprehend the physiological processes covered in the lectures. Overall, the three instructional strategies received positive feedback from the students. Incorporating such cutting-edge and imaginative educational approaches, in conclusion, could significantly aid in managing the pressures that arise during pandemics.

This paper aims to provide an examination of the use of the concept of resilience and its use in service organisation, ecosystem-related literature and the wider social sciences.
Abstract
Purpose
This paper aims to provide an examination of the use of the concept of resilience and its use in service organisation, ecosystem-related literature and the wider social sciences.
Design/methodology/approach
This paper provides a critical review and commentary on the resilience literature in the social and business sciences and its relevance to service organisations.
Findings
Two main approaches towards resilience are identified (engineering and socio-ecological resilience) with each having different assumptions about the nature of resilience with corresponding implications for policymaking, indicator selection and application in a service context. These approaches operate at different scales and possess different properties with respect to the likelihood of enacting transformative service marketing.
Practical implications
Different conceptualisations of resilience have profound implications for resilience-related policymaking as well as understanding change and adaptation in service ecosystems and organisations.
Social implications
The transformative possibilities of resilience are connected to the active enhancement and construction of social capacity by service organisations and the persistent resilience of the resilience concept.
Originality/value
This paper highlights the importance of clearly defining the resilience concept and its implications for research and transformative service organisations.

Abstract
While diversity, equity, inclusion, and belonging (DEIB) in the workplace means making space for all employees, it has unique implications for Indigenous employees who live and work in countries built on colonialism. Indigenous peoples represent diverse groups with unique and rich cultures that in general share values that are more holistic, spiritual, traditional, egalitarian, and other-oriented than non-Indigenous populations. Such distinct worldviews help explain why non-Indigenous organizations struggle to understand and accommodate Indigenous employees’ priorities and goal-oriented behavior. Creating equity, inclusivity, and belonging in the workplace for Indigenous employees requires more than implementing existing organizational practices with a new cultural awareness, it requires rethinking, reframing, and recreating organizational to facilitate a culture of trust. Re-examining organizational norms and assumptions with the ideas of relationship and responsibility that allow collaborative approaches to collective well-being and inclusivity is required. Creating inclusive workspaces requires that attention must be paid to both organizational (group-level) factors, such as organizational cultures of trust, and interpersonal (individual-level) factors, such as interpersonal trust. However, to build foundations of high-functioning and supportive organizational cultures and interpersonal trust that are sustainable, time and resources are necessary. Without this, the ability to reach the crucial result of engaging Indigenous employees and creating safe workplaces serves only to be performative and not meaningful in terms of action, longevity, and the overall well-being of Indigenous people in the workplace.

The authors systematically review empirical dyadic service encounter research published in top-tier journals between 1972 and 2022.
Abstract
Purpose
The authors systematically review empirical dyadic service encounter research published in top-tier journals between 1972 and 2022.
Design/methodology/approach
The authors employed bibliometric techniques, co-citation analysis and bibliographic coupling analysis to map schools of thought and research frontiers within the dyadic service encounter literature. In total, the authors analyzed 155 articles. To ensure inclusion of high-quality research, the authors screened articles from 139 journals with “4” or “4*” ratings on the 2021 Chartered Association of Business Schools (ABS) journal list, in addition to articles published in three service sector-specific journals: Journal of Service Management, Journal of Services Marketing and Journal of Service Theory and Practice.
Findings
The authors' co-citation analysis identified four distinct clusters within the dyadic service encounter literature: (1) shaping and explaining service encounters; (2) emotions in service work; (3) modeling, manipulating and measuring encounter service quality and (4) emotional labor and regulation in dyadic service encounters. Furthermore, the authors' bibliographic coupling analysis generated three research clusters: (1) service encounter characteristics; (2) emotions and emotional labor and (3) service encounter interaction content.
Originality/value
The authors' comprehensive review synthesizes knowledge, summarizing similarities among research clusters within the service encounter realm. Noteworthy are research clusters that clarify the emotion-based underpinnings and reciprocal nature of behaviors and emotions within dyadic encounters. By conducting complementary bibliometric analyses, the authors trace the evolution of the service encounter literature, providing an overview of the present state of dyadic service encounter research. These analyses offer valuable insights into the current landscape of the field, identifying future dyadic service encounter research opportunities.
