Abstract
Purpose
The study investigates the impact of corporate social responsibility (CSR) domain on millennials' brand relationship quality (BRQ). It also attempts to understand how the relationship between CSR domain and millennials' BRQ is moderated by consumer moral foundation and skepticism.
Design/methodology/approach
The study employed a 2 (CSR domain: individual versus group) × 2 (moral foundation: individualizing versus binding) × 2 (consumer skepticism: high versus low) between-subjects experimental design. MANCOVA was performed to examine the hypothesis.
Findings
The results show that group domain CSR practices have more impact on millennials' BRQ compared to individual domain CSR practices. The findings also reported the moderating effect of skepticism and consumer moral foundation in influencing the relationship between CSR domain and millennials' BRQ.
Research limitations/implications
As the study was conducted in India, the findings are not generalizable to customers from other countries.
Practical implications
Practically, the findings will help marketers in designing their CSR practices to enhance BRQ among millennials.
Originality/value
The study has considered CSR as a heterogeneous action (CSR domain: individual versus group-oriented) and measured its impact on millennials' BRQ. The study is the first of its kind to examine the impact of CSR domain (heterogenous CSR action) on millennials' BRQ (BRQ as a multi-dimensional construct) in services industry, specifically for the banks. This study enriches bank marketing literature by adding a new CSR perspective.

Abstract
Purpose
The finite element method (FEM) is used to calculate the two-dimensional anti-plane dynamic response of structure embedded in D’Alembert viscoelastic multilayered soil on the rigid bedrock. This paper aims to research a time-domain absorbing boundary condition (ABC), which should be imposed on the truncation boundary of the finite domain to represent the dynamic interaction between the truncated infinite domain and the finite domain.
Design/methodology/approach
A high-order ABC for scalar wave propagation in the D’Alembert viscoelastic multilayered media is proposed. A new operator separation method and the mode reduction are adopted to construct the time-domain ABC.
Findings
The derivation of the ABC is accurate for the single layer but less accurate for the multilayer. To achieve high accuracy, therefore, the distance from the truncation boundary to the region of interest can be zero for the single layer but need to be about 0.5 times of the total layer height of the infinite domain for the multilayer. Both single-layered and multilayered numerical examples verify that the accuracy of the ABC is almost the same for both cases of only using the modal number excited by dynamic load and using the full modal number of infinite domain. Using the ABC with reduced modes can not only reduce the computation cost but also be more friendly to the stability. Numerical examples demonstrate the superior properties of the proposed ABC with stability, high accuracy and remarkable coupling with the FEM.
Originality/value
A high-order time-domain ABC for scalar wave propagation in the D’Alembert viscoelastic multilayered media is proposed. The proposed ABC is suitable for both linear elastic and D’Alembert viscoelastic media, and it can be coupled seamlessly with the FEM. A new operator separation method combining mode reduction is presented with better stability than the existing methods.

Abstract
Purpose
The study aims to cope with the problems confronted in the skin lesion datasets with less training data toward the classification of melanoma. The vital, challenging issue is the insufficiency of training data that occurred while classifying the lesions as melanoma and non-melanoma.
Design/methodology/approach
In this work, a transfer learning (TL) framework Transfer Constituent Support Vector Machine (TrCSVM) is designed for melanoma classification based on feature-based domain adaptation (FBDA) leveraging the support vector machine (SVM) and Transfer AdaBoost (TrAdaBoost). The working of the framework is twofold: at first, SVM is utilized for domain adaptation for learning much transferrable representation between source and target domain. In the first phase, for homogeneous domain adaptation, it augments features by transforming the data from source and target (different but related) domains in a shared-subspace. In the second phase, for heterogeneous domain adaptation, it leverages knowledge by augmenting features from source to target (different and not related) domains to a shared-subspace. Second, TrAdaBoost is utilized to adjust the weights of wrongly classified data in the newly generated source and target datasets.
Findings
The experimental results empirically prove the superiority of TrCSVM than the state-of-the-art TL methods on less-sized datasets with an accuracy of 98.82%.
Originality/value
Experiments are conducted on six skin lesion datasets and performance is compared based on accuracy, precision, sensitivity, and specificity. The effectiveness of TrCSVM is evaluated on ten other datasets towards testing its generalizing behavior. Its performance is also compared with two existing TL frameworks (TrResampling, TrAdaBoost) for the classification of melanoma.

Abstract
Purpose
This article aims to understand the opportunities as well as the challenges posed by the methods for internationalized access to domain names.
Design/methodology/approach
The paper first provides background information on how domain names are resolved in the domain name system (DNS). It then reviews the various methods for internationalized access to domain names with a focus on their technical implementation and potential problems. Finally, it discusses several important language and policy issues surrounding the methods.
Findings
The methods proposed for internationalized access to domain names can be classified into two groups: ASCII‐compatible encoding; and multilingual keywords. ASCII‐compatible encoding methods, such as the internationalized domain name (IDN) standards specified by the internet engineering task force, seem technically sound since they do not affect existing DNS operations, but they have some structural limitations. Multilingual keyword methods are rather simple and intuitive to use but they are not compatible with one another and so may return different results from the same multilingual keyword query. Also, both ASCII‐compatible encoding and multilingual keyword methods can raise some important issues associated with languages and policies, such as linguistic problems, disputes over IDNs, and multilingual homographs.
Originality/value
The issues discussed in this paper need to be addressed for broad and seamless implementation of the methods for internationalized access to domain names across various languages. The review of the methods and associated issues can prove helpful to those from internet users and domain name registrants to domain name registries and registrars.

Abstract
The incremental radial forging process employs several tens or hundreds of incremental local strokes, so that the entire process is difficult to analyze due to large computation time and large computer memory. The objective of this work is to propose a new numerical scheme of the finite element method, automatic expansion of domain (AED), to reduce computation time and computer memory. In the AED scheme, an effective analysis domain in each local forging step is defined and then the domain is automatically expanded in accordance with the repeated process. In order to verify the validity of the criterion for the AED scheme and the applicability of the AED scheme, two‐dimensional incremental plane‐strain forging process is first analyzed using the proposed scheme with various criteria and full domain. In addition, three‐dimensional incremental radial forging process is analyzed to verify the applicability of the proposed scheme to a practical incremental forging process.

Abstract
Purpose
This study aims to introduce the concept of dissociative threat, which is the fear of being associated with an undesirable (dissociative) group as a result of demonstrating ability in a domain that is stereotypically linked to that group. Consumers experiencing dissociative threats use inability signaling as a self-presentational strategy in which they present themselves as lacking ability in the dissociative domain.
Design/methodology/approach
Five experimental studies were conducted to test whether consumers experience threat in dissociative domains and to examine factors that influence this threat.
Findings
Results showed that dissociative threat adversely affects consumers’ performance at tasks that require using products linked to dissociative groups. Threatened participants reported intentions to perform poorly and train for a longer time in preparation for such tasks, thus signaling low ability in dissociative domains. Additionally, when participants who were experiencing dissociative threats received confirmation that they lacked ability in that domain, their performance at these tasks improved.
Research limitations/implications
This study expands the knowledge on strategies, including inability signaling, that consumers use to avoid being linked to dissociative groups.
Practical implications
The findings suggest to marketers that stereotypes that link their products to certain consumer segments can threaten other consumers. Factors that shape and alleviate this threat are identified, which may help companies who are marketing such products.
Originality/value
This study extends the current understanding of stereotype threat and proposes a new self-presentational strategy, that has not been documented yet in the literature (i.e. inability signaling), that consumers use to deal with the dissociative threat.

Abstract
Purpose
This paper aims to review analogical reasoning work to distil and apply procedural guidelines that aid theoreticians to develop novel analogies.
Design/methodology/approach
The authors reviewed 189 studies from 1980 to 2020 to identify analogical reasoning guidelines.
Findings
Results revealed four procedural steps for the introduction of novel analogies: target and source domain selection; domain image mapping; relevance assessment; and proposition drafting. […] shallow lakes constitute the source domain and sustainable supply chain management represents the target domain.
Research limitations/implications
The identified procedural guidelines can help future scholars to develop novel analogies with rigor and structure. The paper provides an agenda for new research that addresses gaps in current studies that reason by analogy.
Originality/value
This paper distils and applies analogical reasoning guidelines for the development of novel analogies, extending and complementing much existing theorizing on reasoning by analogy. Additionally, disjointed and fragmented research findings are synthesized to yield a comprehensive understanding of analogical reasoning, which can serve as a foundation for future theorizing in sustainable supply chain management and beyond.

Abstract
Purpose
Based on the conservation of resources (COR) theory (Hobfoll, 1989, 2002), this study first investigates the direct influence of core self-evaluations (CSEs) on work-to-family (W → F) and family-to-work (F → W) conflicts. Second, it tests the mediating impact of Social support from work and home domains in the associations between CSEs and both directions of work-family conflict. This study finally examines the moderating influence of CSEs in the associations between work and home domain social support and both directions of work-family conflict.
Design/methodology/approach
Human resources professionals (629), and engineers (169) employed in Canada completed an online survey. Both directions of work-family conflict were measured as well as CSEs, and work and home domain social support.
Findings
Results indicate that higher CSEs are associated with lower W → F and F → W conflicts. They also suggest an indirect association between CSEs and W → F conflict through supervisor support. The indirect association between CSEs and F → W conflict through home domain social support was also supported. Besides, it appears that CSEs moderate the association between home support and F → W conflict.
Research limitations/implications
Our findings underscore the relevance of considering both dispositional and environmental factors together in work-life research. Results question within- vs. cross-domain conceptualizations of work-life spillover. They also indicate how both differential choice and effectiveness operate in conjunction with managing work-life domains.
Originality/value
The research presents a comprehensive model linking work-family conflict, social support and CSEs. It draws from an integrative personality framework (Judge et al., 1998) and COR theory (Hobfoll, 1989) to explore the underlying processes of CSEs, often inferred but not specified or incorporated into work-life research.

Abstract
The authors explore how entrepreneurs with limited resources legitimated (or failed to legitimate) a new organizational category in different jurisdictions in Canada despite severe resistance. The authors identify three meso-level domains of institutional action (public, administrative, and legal), where actors intervene to change their macro-institutional environment. The findings suggest that these domains mediate the relationship between micro-level agency and macro-level institutions. The authors describe how macro-level consensus about the category legitimacy emerges through a competition between judgments embedded in different discourses and how a particular discourse attains validity, forcing other actors to change their initial unfavorable legitimacy judgments and recognize the category’s legitimacy.
