The main purpose of this paper is to introduce the gradient discretisation method (GDM) to a system of reaction diffusion equations subject to non-homogeneous Dirichlet boundary conditions. Then, the authors show that the GDM provides a comprehensive convergence analysis of several numerical methods for the considered model. The convergence is established without non-physical regularity assumptions on the solutions.

In this paper, the authors use the GDM to discretise a system of reaction diffusion equations with non-homogeneous Dirichlet boundary conditions.

The authors provide a generic convergence analysis of a system of reaction diffusion equations. The authors introduce a specific example of numerical scheme that fits in the gradient discretisation method. The authors conduct a numerical test to measure the efficiency of the proposed method.

This work provides a unified convergence analysis of several numerical methods for a system of reaction diffusion equations. The generic convergence is proved under the classical assumptions on the solutions.

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.

The purpose of this paper is to examine how young British South Asian adults’ dual cultural identity is exhibited and reaffirmed through the appropriation of selfies.

The research adopts a qualitative perspective and utilises a combination of in-depth interviews and netnographic data.

The appropriation of the selfie phenomenon by young British South Asian adults reifies, endorses and reinforces their dual cultural identity. As such, their dual cultural identity is influenced by four factors: consonance between host and ancestral cultures, situational constraints, contextual requirements and convenience.

In terms of the selfie phenomenon, the study makes two major contributions: first, it analyses young British South Asian adults’ cultural dualism. Second, it explicates how their acculturation and their dual cultural identity are expressed through the appropriation of the selfie phenomenon.

Since young British South Asians represent a significant, and distinct, market, organisations serving this market can marshal insights from this research. As such, managers who apprise themselves of the selfie phenomenon of this group are better placed to meet their consumer needs. Account, therefore, should be taken of their twofold cultural identity and dual British/Asian identification. In particular, consideration should be given to their distinct and demonstrable traits apropos religiosity and social, communal, and familial bonding. The characteristics were clearly evident via their interactions within social media. Consequently, senior marketing managers can utilise the aforementioned in positioning their organisations, their brands and their products and services.

The study details a new quadripartite framework for analysing young British South Asian adults’ acculturation that leads to the formation of their dual cultural identity and presents a dynamic model that explicates how cultural identity is expressed through the use and appropriation of technology.

In the presence of coronavirus disease 2019 (COVID-19), due to the social distance restriction, consumers' regular consumption behaviors and patterns have been changing fundamentally. Thereafter, an innovative group buying model has emerged and developed explosively with a specific focus on consumer's location, known as community-based group buying (CGB). The purpose of this paper is to investigate the transfer mechanism of user's trust in dyadic contexts of social and commercial role-playing in the CGB program.

This study adopts an empirical research method, with an online and offline questionnaire survey, a total of 382 responses have been obtained. Then, both descriptive analysis and hierarchical regression analysis are conducted to explore the dual roles of group leader and its corresponding effects on consumers' trust (i.e. emotional trust and behavioral trust) and engagement actions (i.e. purchase and share) in the CGB program.

Results indicate that resident's trust and their perception of group leader's friend role can positively enhance their engagement actions in the CGB programs. Meanwhile, for the purpose of profit maximization, the group leader is more willing to play a friend role in transactions no matter whether the role conflict exists.

Research findings provide some managerial insights for CGB platform on the selection and training of group leaders and the incentive mechanism design.

Compared to younger and older generation migrants, middle-aged migrants in the diaspora seem to be more conflicted regarding their belonging. This paper aims to explore how middle-aged migrants in the diaspora define themselves in space and time.

The paper is based on ethnographic fieldwork done among Malawian migrants (herein referred to as Lydiatians) settled at Lydiate informal settlement in peri-urban Zimbabwe.

The paper reveals that, while younger migrants have a “radical transnational stance”, and older migrants regard their place of settlement as their final home, middle-aged migrants prefer to maintain a “strategic dual sense of place” regarding their place of settlement in the diaspora. These middle-aged migrants can be entrepreneurs considering their current settlement as a strategic place for petty commodity trading or those who find informal settlements to provide needed opportunities for cheap housing as the migrants pursue work in the nearby towns.

The paper offers a deeper understanding of how middle-aged migrants navigate their sense of place and contribute to host nations by functioning as key resources, dynamizing local economies through entrepreneurial activities and labour provision for various industries. The implications of this research should encourage states to positively interact with migrants, leveraging their potential for societal and economic development.

The finding that migrants in the diaspora have a dual, strategic view of their settlements is fascinating, if not new. Before this, scholars presented migrants as transnational figures, successively moving to a better place, which finally becomes home. However, the data presented in this paper suggests that this characterization associating migrants with maintaining a “stable, sedentary, bounded and fixed perception of home” is oversimplified. This is because migrants can sometimes continue to cherish the idea of informal settlements in the diaspora as home, just as the migrants also entertain the nearby established towns as useful places in their life.
