Abstract
A boundary element method in terms of the field variables is applied to three‐dimensional electromagnetic scattering problems. Especially, the influence of a dipole excited field on low conducting materials situated very close to the antenna will be discussed. We use higher order edge elements of quadilateral shape for the field approximation on curved surfaces. The tangential components of the unknown field variables are interpolated by vector element functions. The Galerkin method is implemented to obtain a set of linear equations. The applicability of the proposed edge element is investigated by the comparison of different BEM‐formulations and FEM‐results.

Abstract
This chapter is a collection of reflections on the broader concept of my “story to live by” (Connelly & Clandinin, 1990; Craig, 2008, 2014) as a beginning English Language Arts teacher. Burrowing deeply into the impact of a single phrase from a conversation with a found mentor at the close of my first year, the chapter explores the journey of sustaining in the profession by examining what is here within discussed as a narrative undercurrent that carries each educator toward his or her “best-loved Self” (Craig, 2013; Schwab, 1954/1978). This concept is introduced, and then reflected upon in correlation with the development of knowledge communities (Olson & Craig, 2001; Craig & Huber, 2007), narrative authority (Olson, 1995), and narrative identity (Connelly & Clandinin, 1999; McAdams, Josselson & Lieblich, 2006).
In meditating on the broader narrative, I arrived at the conclusion that the conversation referenced initiated my discovering essential elements of my best-loved Self, and my seeking to actualize them within a forged knowledge community. I moved forward and expanded my knowledge “for,” “in,” and “of” practice (Cochran-Smith & Lytle, 1998). Through this process, I authored and re-authored myself through conflicts noted across the literature as factors contributing to beginning teacher attrition rates (Craig, 2014; Schaefer, 2013) and preserved my story to live by.

Abstract
A well-established method of qualitative investigation is the focus group; a form of data collection involving multiple participants. Unlike interviews, focus groups enable participants to offer their opinion in a way that may be guided, inspired, or refuted by others, which enables a rich collection of perspectives to be gathered for research purposes. While traditionally focus groups have been conducted in the face-to-face setting, the COVID-19 pandemic led many researchers to adapt their practice, conducting online focus groups from their home. This paper describes some practical guidance for researchers who wish to conduct focus groups online. This guidance was derived using an autoethnographic approach, drawing on the experience of a researcher working on a large educational development project, reflecting on what was learned from running several focus group sessions. It is envisaged this work will act as an informative guide for researchers who wish to conduct research from home, or use an online medium to conduct focus groups, beyond the pandemic.

Abstract
This paper deals with the inverse scattering problem of reconstructing the material properties of perfectly conducting or dielectric cylindrical objects. The material properties are reconstructed from measured far‐field scattering data provided by the Electromagnetics Technology Division, AFRL/SNH, 31 Grenier Street, Hanscom AFB, MA 01731‐3010. The measured data have to be calibrated for use in our reconstruction algorithm. The inverse scattering problem formulated as unconstrained nonlinear optimization problem is numerically solved using an iterative scheme with a variable calibration factor which will be determined during the optimization process. Numerical examples show the successful application of the method to the measured data.

Abstract
This chapter features our innovative endeavors to inquire into an African-American student's potentially sensitive stories in a methodologically fluid and ethically delicate manner through two generative methods: digital narrative inquiry and musical narrative inquiry. Through a meta-level “inquiry into inquiry” approach, this work explores how we engaged in the digital and musical restorying of the participant's “Wounded Healer” narrative and uncovered its dynamism, cultural richness, and nuances. We subsequently represented the findings in humanizing ways using multimedia and music. Drawing on the insights from exploring these novel methods of digital and musical inquiry, our work illuminates noteworthy elements of narrative research: generativity, transformativity, interpersonal ethics, aesthetic ethics, and communal ethics. Additionally, the potential issue of trustworthiness in fluid narrative inquiries is addressed.

Abstract
Amid the multitude of economic effects emanating from impositions of COVID-19, workers in the tourism sector are potentially experiencing significant psychosocial impacts. These effects are compounded by the uncertainty of pathways for positive change and the precariousness of adjustments to life and livelihoods. Their attitudes to the newly imposed circumstances are possibly conditioned by a sense of hope which may have implications for their adaptations in the face of sudden or slow change. In this chapter, we argue that one’s sense of hope represents an important component of psychosocial well-being and may even be visualized as a necessary component of adaptation. Hope is conceptualized as a cognitive process that entails thinking and planning in order to achieve proposed goals (Snyder, Irving, & Anderson, 1991; Snyder, Lopez, Shorey, Rand, & Feldman, 2003) and can be operationalized into three core components: goals, pathways, and agency. Based on in-depth interviews and a questionnaire survey administered to former accommodation workers in the Negril tourism industry, this chapter examines expressions of hope(lessness) existing among workers displaced by COVID-19. It potentially provides nuanced understandings of hope as a necessary raw material for adaptation initiatives and explores ways in which a sense of hope could be harnessed in the face of disasters and despair.

Abstract
Purpose
This study explores the influence of the coronavirus disease 2019 (COVID-19) career experience on the investment behavior and risk tolerance of chief executive officers (CEOs). Specifically, this study focuses on CEOs' abilities to allocate financial assets and maintain solvency.
Design/methodology/approach
This study adopts a comprehensive approach to analyze financial assets and asset-to-liability ratios. Financial data and individual information of CEOs from listed companies are collected from 2020Q1 to 2021Q4, along with statistics on confirmed COVID-19 cases. Instrumental and alternative variables are used to examine the robustness and endogeneity of the research, ensuring a thorough analysis.
Findings
A significant positive correlation is revealed between CEOs' COVID-19 career experience and their capacity to effectively allocate financial assets. However, COVID-19 has a negative effect on firm performance in terms of solvency. These findings contribute to the empirical evidence linking the pandemic to company performance, representing part of the initial research in this area.
Originality/value
The study suggests that the implementation of potential policy implications, such as loose monetary policies and tax and fee reduction measures, may alleviate the tax burden on listed companies.
