This paper addresses a significant research gap in the study of Rayleigh surface wave propagation within a piezoelectric medium characterized by piezoelectric properties, thermal effects and voids. Previous research has often overlooked the crucial aspects related to voids. This study aims to provide analytical solutions for Rayleigh waves propagating through a medium consisting of a nonlocal piezo-thermo-elastic material with voids under the Moore–Gibson–Thompson thermo-elasticity theory with memory dependencies.

The analytical solutions are derived using a wave-mode method, and roots are computed from the characteristic equation using the Durand–Kerner method. These roots are then filtered based on the decay condition of surface waves. The analysis pertains to a medium subjected to stress-free and isothermal boundary conditions.

Computational simulations are performed to determine the attenuation coefficient and phase velocity of Rayleigh waves. This investigation goes beyond mere calculations and examines particle motion to gain deeper insights into Rayleigh wave propagation. Furthermore, this investigates how kernel function and nonlocal parameters influence these wave phenomena.

The results of this study reveal several unique cases that significantly contribute to the understanding of Rayleigh wave propagation within this intricate material system, particularly in the presence of voids.

This investigation provides valuable insights into the synergistic dynamics among piezoelectric constituents, void structures and Rayleigh wave propagation, enabling advancements in sensor technology, augmented energy harvesting methodologies and pioneering seismic monitoring approaches.

This study formulates a novel governing equation for a nonlocal piezo-thermo-elastic medium with voids, highlighting the significance of Rayleigh waves and investigating the impact of memory.

Work-life flexibility policies (e.g., flextime, telework, part-time, right-to-disconnect, and leaves) are increasingly important to employers as productivity and well-being strategies. However, policies have not lived up to their potential. In this chapter, the authors argue for increased research attention to implementation and work-life intersectionality considerations influencing effectiveness. Drawing on a typology that conceptualizes flexibility policies as offering employees control across five dimensions of the work role boundary (temporal, spatial, size, permeability, and continuity), the authors develop a model identifying the multilevel moderators and mechanisms of boundary control shaping relationships between using flexibility and work and home performance. Next, the authors review this model with an intersectional lens. The authors direct scholars’ attention to growing workforce diversity and increased variation in flexibility policy experiences, particularly for individuals with higher work-life intersectionality, which is defined as having multiple intersecting identities (e.g., gender, caregiving, and race), that are stigmatized, and link to having less access to and/or benefits from societal resources to support managing the work-life interface in a social context. Such an intersectional focus would address the important need to shift work-life and flexibility research from variable to person-centered approaches. The authors identify six research considerations on work-life intersectionality in order to illuminate how traditionally assumed work-life relationships need to be revisited to address growing variation in: access, needs, and preferences for work-life flexibility; work and nonwork experiences; and benefits from using flexibility policies. The authors hope that this chapter will spur a conversation on how the work-life interface and flexibility policy processes and outcomes may increasingly differ for individuals with higher work-life intersectionality compared to those with lower work-life intersectionality in the context of organizational and social systems that may perpetuate growing work-life and job inequality.

This study aims to investigate consumers’ construction of food localness through the politics of belonging in a regional context.

Following a socio-spatial lens and considering the “realm of meaning” of place, this research focusses on local consumers’ lived meanings of “local” food choice, and hence adopts a phenomenological approach to the data collection and analysis of 20 in-depth interviews with residents of the Italian region of Marche.

Drawing on Trudeau’s (2006) politics of belonging, this study reveals three interconnected themes which show how local consumers articulate a local food “orthodoxy” and how their discourses and practices draw and maintain a boundary between local and non-local food, whereby local food is considered “autochthonous” of rural space. Thus, this study’s participants construct a local food landscape, conveying rural (vs urban) meanings through which food acquires “localness” (vs non-“localness”) status.

There exists further theoretical opportunity to consider local consumers’ construction of food localness through the politics of belonging in terms of non-representational theory (Thrift, 2008), to help reveal added nuances to the construction of food localness as well as to the complex process of formulating place meaning.

The findings provide considerable scope for food producers, manufacturers and/or marketers to differentiate local food products by enhancing consumers’ direct experience of it in relation to rural space. Thus, enabling local food producers to convey rural (vs urban) meanings to consumers, who would develop an orthodoxy guiding future choice.

The findings enable regional promoters and food policymakers to leverage the symbolic distinctiveness of food autochthony to promote place and encourage consumers to participate in their local food system.

By using the politics of belonging as an analytical framework, this study shows that the urban–rural dichotomy – rather than being an obsolete epistemological category – fuels politics of belonging dynamics, and that local food consumers socially construct food localness not merely as a romanticisation of rurality but as a territorial expression of the contemporary local/non-local cultural conflict implied in the politics of belonging. Thus, this study advances our theoretical understanding by demonstrating that food “becomes” local and therefore, builds on extant food localness conceptualisations.

Though prior research has addressed customer engagement (CE) with a focal object (e.g. a brand), the dynamics characterizing customers' engagement with different objects and the potential spillover from a customer's engagement with one object to that with another remains tenuous, exposing an important literature-based gap. The authors, therefore, develop a model proposing the existence of a spillover effect from customers' brand engagement to their engagement with brand-related content and suggest customers' personality trait of conscientiousness to moderate this effect.

An online survey-based experiment using 380 Danish Facebook users was conducted to test the model.

The results suggest customers' brand engagement as a significant predictor of their engagement with brand-related content, corroborating the proposed spillover effect. A weaker spillover effect is observed for highly (vs less) conscientious customers, substantiating the moderating role of customer conscientiousness. Moreover, customer conscientiousness is found to interact with brand content-related (i.e. commenting/content creation) task type and brand type (i.e. utilitarian/hedonic) (e.g. more conscientious customers are less likely to engage in brand-related content creation vs. commenting tasks), weakening the spillover effect.

This study extends prior research by quantitatively corroborating an intra-individual CE-based spillover effect from customers' brand engagement to their engagement with brand-related content. The authors also unearth a moderating role of customer conscientiousness, which interacts with brand- and brand content-related task type, on the spillover effect, informing the development of digital marketing strategies.
