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.

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.

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.

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.

Talent management in higher education institutes is an underexplored topic. Only a small portion of talent management publications is focussed on describing talent management in higher education institutes. In this chapter, we give an overview of the most important topics in the talent management literature in general and link it to what is known about these issues in higher education. It discusses the definition of talent and talent management, the talent management process and the multilevel outcomes of talent management, the fairness and justice issues related to talent management and the importance of embedding the analysis of talent management in its broader organizational and institutional context. In the final part of this introduction chapter, we will explain how the talent management topics are discussed in the subsequent chapters of this book.

The case was developed in partnership with the focal entrepreneur, Michael Maher, and relies on primary data he provided.

This case is based on the experiences of Michael Maher, a Cincinnati, OH (USA)-based entrepreneur whose ecommerce business failed in 2016, largely due to a major change in Amazon’s marketplace. The case puts students in Michael’s position as this is happening. It focuses on the fact that although Michael knew, logically, that the failure was largely beyond his control, and that he “should” think about failure as a learning opportunity, emotionally and psychologically he felt terrible. The case forces students to confront this reality as they reflect on the situation and determine how Michael might best respond. The case is intended to help instructors address the often undiscussed “dark sides” of entrepreneurship, which can include financial hardship and intense stress, and also cause or exacerbate depression, substance abuse and other mental and physical health issues (Shepherd, 2019). These challenges frequently impact other involved stakeholders (e.g. family members) and, as a result, can negatively impact familial dynamics, friendships and other relationships. The goal of the case is not to discourage students from entrepreneurial activity, but to make them aware of these potential dark sides. In addition to awareness, the teaching plan is designed to provide students with tools and strategies to recognize and navigate the dark sides.

This case is appropriate for introductory entrepreneurship courses at the undergraduate and graduate level. It might also be used in more advanced courses focused on developing/launching a new venture (e.g. “New Venture Planning” courses). The case can be taught at any point within a given course, but it is recommended after students have developed an understanding of key entrepreneurship concepts in the focal course or in previous courses. In particular, students should have a working knowledge of the concept of “learning from failure” and other tenets of the lean startup and similar approaches (Blank, 2013; Ries, 2011). This background knowledge is important because the case confronts students with the reality that, although “learning from failure” is central to entrepreneurship, that does not necessarily eliminate the social and psychological challenges that often follow failures. Assuming students possess this background knowledge, the case is most effectively used early in a course to make students aware of the “dark sides” they might confront as an entrepreneur and set the stage for the development of strategies and skills to navigate those dark sides throughout the rest of the course. The case’s brevity means it can be assigned to be read in advance of class or during the class session in which it is being covered.

This article seeks to provide a fresh perspective on the methodological approach to studying caregiving in a transnational context by analysing, local caregiver’s lifeworld, informal interpreting/translation and professional communication with foreign retirees.

This project explores the complex and multifaceted meanings of everyday objects through diffractive vignettes to illuminate the communicative entanglements that arise between caregivers and foreign retirees receiving care in Thailand. To identify intra-actions in caregiving, we collected data through informal interviews, observations and various artefacts before combining them in a group of potential communicative relationships by creating a narrative summary of situations.

Communicative relationships in the vignettes are multidimensional, with diverse logics underlying choices, rapport formation and communication effectiveness. This premise also illuminates how caregivers perceive and intra-act with their accommodation strategies, considering trust, comfort and comprehension. Our findings were also discussed with the concept of communication accommodation theory.

As an extension of the post-humanist approach to the diffractive reading of vignettes, this study sees its value in studying agent-related informal translation/interpreting and human-to-human relationships.

This study investigates the mediating role of personal initiative taking in the link between employees' exposure to transformational leadership and their engagement in creative behavior, as well as a potential catalytic role of perceived work overload in this process.

The research hypotheses were tested with survey data collected among employees of a large organization that operates in the telecommunications sector.

Transformational leadership translates into enhanced creative work efforts among employees, because these employees adopt an action-based approach toward work. This mediating role of personal initiative taking is particularly prominent among employees who encounter excessive workloads in their daily jobs, because their initiative and creativity promise solutions to this resource-draining work situation.

For human resource managers, this study reveals that employees who go out of their way to address problem situations offer an important means by which a leadership style that inspires and challenges followers can be leveraged to produce enhanced creative outcomes. It also pinpoints how this process can be triggered by employees' beliefs that work demands are excessive.

This study adds to prior research by detailing a hitherto overlooked factor (personal initiative) and catalyst (perceived work overload), related to the translation of transformational leadership into increased creative behavior.

This paper aims to study antiques enthusiasts’ perspectives on the recent stagnancy in the antiques market, along with their suggestions on how the antiques trade can forge a more secure path forward.

Using a qualitative analysis approach through netnography, this paper examines archived comments of antiques enthusiasts on a “r/antiques” subreddit.

This research studies connoisseurs’ insights into the reduction in antiques sales experienced by a wide cross-section of sellers, particularly independent and small business retailers. Specifically, the results of this paper’s discourse analysis show that technological advances on one hand and socioeconomic factors (e.g. income, family structure and lifestyle) on the other hand have had a significant negative impact on demand for antiques. In addition, specific attributes such as authenticity and sustainability emerged as potential key marketing elements for invigorating the broader public’s interest in purchasing antiques.

Despite their significant insights into the antiques market, antiques enthusiasts have not received the academic attention they deserve. Through discourse analysis of comments in an online antiques community, this paper draws attention to the vulnerabilities of antiques markets to a protracted climate of slow sales, while highlighting potential strategies on how to turn the tide for struggling antiques stores.

Despite being a seminal explanation of the workforce emotional experiences, capable of mapping the path from the antecedents to consequences, affective events theory (AET) only offers a “macrostructure” of a working environment. To date, little is known about the universal features of the work environment that may guide the understanding of imperative work aspects triggering employees’ emotions at work. Hence, the study proposes and validates that Stafford Beer’s viable system model (VSM) can provide a holistic view of the organizational work environment, enabling a comprehensive understanding of work events or factors triggering workforce emotions.

First, the VSM structural layout is used to fill in the “macrostructure” of the “working environment” in AET to diagnose the functional and relational aspects of the work and the related work events occurring within. Using a deductive approach, 31 work events were adopted to determine the impact of VSM-based work environment events on the employees’ emotional experiences and subsequent work attitudes (job satisfaction) and behaviors (citizenship behavior). To field test the proposed nexus of VSM and AET, the survey was conducted on two hundred and fifteen employees from 39 different organizations. PLS-SEM tested the explanatory power of the suggested VSM’s systemic approach for understanding the affective work environment in totality.

The findings confirmed that the VSM metalanguage provides a holistic view of the organizational functioning and social connectivity disposing of affective work events, helpful in assessing their aggregate influence on employees’ emotions and work-related outcomes.

The findings identify how employees' emotions can be triggered by everyday work operations and social relations at work, which can affect their extra-role behaviors and necessary work-related attitudes.

The study utilized Beer’s VSM framework based on the systemic principle of “holistic view” for ascertaining the affective work environment and its related features holistically, which filled in well the macrostructure of “work environment features” with micro-structures of organizational inter-related aspects which are yet to be known in AET – a seminal explanation for managing workforce emotions.

The massive investment in, and development of, automated and connected transport (ACT) technology development has triggered much debate about this breakthrough technology’s potential positive and negative impacts. Multiple studies have explored the potential direct implications for users in terms of road safety, ‘productive’ travel time, mobility of the elderly and physically less mobile persons, as well as indirect impacts such as reduced emissions and freed road space. Through a critical review of the literature on ACT deployment types and discussions with an expert working group on the wider impacts of ACT implementation, this chapter examines four distinct deployment types of ACT technology and their opportunities and threats in transitioning toward inclusive transport systems. Of the four types, we posit that ACT-based public transport has the greatest potential to contribute to a more inclusive mobility future. Examining the case of Singapore using policy documents, academic literature and interviews with representatives of public and private sectors and academia, the chapter draws policy recommendations for governance toward more inclusive ACT innovation and deployment.
