Abstract
The computational efficiency of subspace iteration is addressed relative to the data structures adopted for the very large and generally sparse coefficient matrices. The frequent triangulations and matrix multiplications demand that access to the terms in the coefficient matrices be unbiased. Reliance on virtual memory (paging) operating systems with no special considerations for localized data access is not adequate. Specific data structures must be designed that accommodate the needs of the numerical algorithm yet eliminate unnecessary paging. An implementation of the subspace iteration method using hypermatrix data structures is presented. Use of hypermatrices is shown to provide unbiased and localized data access. The various modifications to the conventional formulation are described and an example problem illustrates the potential benefits of the hypermatrix formulation. Possibilities for adapting hypermatrix data structures to new supercomputer architectures are discussed.

Abstract
This chapter proposes a global agenda to eliminate racism in nursing by targeting reform at nursing education administration internationally. First, the history of racism in nursing is reviewed, along with two models – the diversity model and the cultural competence model – that were applied unsuccessfully to counteract racism in nursing. Second, a description of how racism is entrenched in nursing leadership globally is presented. Third, the recalcitrant structures that serve to maintain institutionalized racism (IR) in the international nursing education system are carefully examined. Specifically, the components and constructs involved in IR in nursing education are delineated, and the way in which these negatively impact both ethnic minority (EM) students and faculty are explained. Based on this, a global agenda to eliminate racism in nursing education internationally is proposed. Eliminating racism in higher education in nursing is a mandatory social responsibility if global healthcare is ever to be equitable. Five actionable recommendations are made to eliminate racism in higher education are summarized as follows: (1) components of nursing programs which are designed to eliminate racism in nursing education should be governed at the country level, (2) to design and implement a system of surveillance of the global nursing community to enable standardized measurement to ensure nursing education programs in all countries are meeting anti-racism benchmark targets, (3) nursing education programs should be established worldwide to provide individual pipeline and mentorship programs to ensure the career success of EM nursing students and faculty, (4) nursing education programs should be conducted to reduce barriers to EM participation in these individual support programs, and (5) nursing education programs are required to teach their nursing faculty skills in developing anti-racist curricula that seeks to eliminate implicit bias.

Abstract
Teams focus on a common and valued goal, and effective teams are able to alter their behaviors in pursuit of this goal. When teams are viewed in the context of a dynamic environment, they must adapt to challenges in the environment in order to maintain team effectiveness. In this light, we describe various sources of team variation and how they combine with individual-level, team-level, and dynamical mechanisms for maintaining team effectiveness in a dynamic environment. The combination of these elements produces a systems view of team effectiveness. Our goals are to begin to define, both in words and in operational terms, team effectiveness from this perspective and to evaluate this definition in the context of team training using intelligent tutoring systems (team ITS). In addressing these goals, we present an example of real-time analysis of team effectiveness and some challenges for team ITS training based on a dynamical systems view of team effectiveness.

Abstract
The finite strip method has been shown to apply to many problems in continuum mechanics. Within the constraints of the method, it has been shown to be superior to the finite element method in terms of data preparation, program complexity and execution time. The finite strip method has been recently extended to groundwater flow problems. The orthogonality of appropriately selected shape functions gives the finite strip method its computational efficiency. The uncoupling achieved from this orthogonality also produces a numerical method which is intrinsically parallel. Consequently, additional efficiencies can be obtained in a parallel environment. Numerical studies of the finite strip method to model a two‐dimensional groundwater flow problem demonstrate the accuracy of the solution and the superior performance of the numerical procedure in a parallel environment.

Abstract
Cultural and creative industries (CCIs) have been argued to play an important role in achieving the sustainable development goals (SDGs). However, the mechanisms through which CCIs contribute to the attainment of SDGs remain underexplored. In this study, the authors adopt a network perspective to examine how the structure of a local CCI network relates to its local sustainability performance. By examining a database of 210,182 networked firms out of 1.34 million CCI firms across 294 cities in China, the authors conclude that both the scale and the density of a local CCI network improve the city’s performance in terms of attaining SDGs 8–12. The authors discuss the implications of these findings and propose future research avenues in international business.

Abstract
Expectations play a crucial role in finance, macroeconomics, monetary economics, and fiscal policy. In the last decade a rapidly increasing number of laboratory experiments have been performed to study individual expectation formation, the interactions of individual forecasting rules, and the aggregate macro behavior they co-create. The aim of this article is to provide a comprehensive literature survey on laboratory experiments on expectations in macroeconomics and finance. In particular, we discuss the extent to which expectations are rational or may be described by simple forecasting heuristics, at the individual as well as the aggregate level.

Abstract
This chapter introduces the tourism–disaster–conflict nexus through a comprehensive review of the contemporary social science literature. After reviewing conceptual definitions of tourism, disaster and conflict, the chapter explores various axes that link through this nexus. The linkages between tourism and disaster include tourism as a trigger or amplifier of disasters, the impacts of disasters on the tourism industry, tourism as a driver of disaster recovery and disaster risk reduction strategies in the tourism sector. Linkages between tourism and conflict include the idea that tourism can be a force for peace and stability, the niche status of danger zone or dark heritage tourism, the concept of phoenix tourism in post-conflict destination rebranding, tourism and cultural conflicts, and tourism’s conflicts over land and resources. Linkages between disaster and conflict include disasters as triggers or intensifiers of civil conflict, disaster diplomacy and conflict resolution, disaster capitalism, and gender-based violence and intra-household conflict in the wake of disasters. These are some of the conversations that organise this volume, and this introductory chapter ends with a summary of the chapters that follow.

Abstract
This chapter proposes that tax education, proxied by Master of Science in Taxation (MST) degree, has substantial influence on chief financial officers’ (CFOs) knowledge, skill sets, values, and cognitive preferences and further influences their decisions in tax reporting. By empirically examining the relation between CFOs with MST degree and their companies' tax compliance based on US data between 2004 and 2016, we find that CFOs with MST degree are associated with improved tax compliance, suggesting that US MST education, beyond general accounting education, cultivates graduates with higher levels of professionalism and ethics in the field of taxation. Moreover, we find that CFOs' tenure, age, and compensation influence the relation between tax education and tax compliance, suggesting company's compensation and employee policies influence executives' tax decisions. Finally, we find that pressures from financial reporting and CEOs with accounting educational background could alleviate the role of CFOs with accounting educational background in tax reporting, while institutional owners could strengthen the role of CFOs. This chapter provides evidence regarding the social implication of MST program and has important managerial implication to tax compliance, executive recruitment, and corporate governance.

Abstract
The turbulent phase of COVID-19 has caused uncertainty as governments fail to develop coherent strategies for cutting emissions and are struggling to match the rhetoric of sustainable activities with actions (Barbier & Burgess, 2020; Cawthorn, Kennaugh, & Ferreira, 2021). In the recent past, firms have failed in their plans to decarbonise their key sectors such as the retail sector in the United Kingdom So far, retailers' commitment to achieving net zero emissions has been an important pledge but delivery is nowhere closer to their promises (Henriques, 2020). The firms' climate targets are not going to be met by magic as serious action is needed to fulfil the promises.
Fossil fuels have led to a drastic increase in carbon emissions in the world over the last decade. Firms championing cleaner energy and low carbon technologies are needed to cut emissions. Renewable energy sources such as wind energy can help reducing the dependency of fossil fuels (Boretti, 2020; Ebhota & Jen, 2020). Wind is an indirect form of solar energy which can provide environment-friendly option in uncertain times and can provide long-term sustainability of global economy. Solar energy technologies have the potential to decrease climate change through energy-related emissions (Li, Dai, & Cui, 2020). Increasing energy demand has initiated a focus on using hydrogen from water as a substitute for oil and fossil fuels (Boretti, 2020).
The first part of the chapter discusses theoretical perspectives of sustainable development and environmental performance with regards to three main issues: energy, water and carbon emissions, whereas the later part highlights the importance of solar technology as a low-polluted alternative to fossil fuels in the retail sector. Sustainable development of energy, water and environmental precautions such as reducing carbon emissions are of interest to wider branches of industries including retail, energy and water sector, governmental policymakers, researchers, educators and society. The purpose of this chapter is to increase the debate of the key issues of sustainable development regarding environment, energy and water in the modern times.
