Abstract
Purpose
Drawing from transformative service research (TSR) and service ecosystem perspectives, the author seeks to provide multi-level insights into gaming service systems and call to action how this knowledge can contribute to cultivating socially responsible gaming by addressing the following research questions: What insights from service ecosystem and TSR literature can help optimise value co-creation and cultivate socially responsible practices in digital gaming services? What future research directions could advance the understanding of digital gaming services and their potential to develop a responsible gaming ecosystem that balances social well-being with commercial success?
Design/methodology/approach
Adopting a conceptual approach of theory synthesis and adaptation, the author discusses four overarching themes alongside key research gaps and directions crucial for understanding the dynamics of gaming ecosystem.
Findings
The central themes – “Exploring individuals as game service consumers”, “Gaming service exchange dynamics among meso-level stakeholders”, “A macro lens to gaming service ecosystem” and “The complexities of multi-actor dynamics and interdependencies” – shed light on how responsible services can be fostered.
Research limitations/implications
Given the absence of a well-defined scope for understanding responsible gaming, future research should develop a typology to capture its multifaceted aspects. Expanding beyond micro-level analysis, conducting consultation interviews with industry practitioners and policymakers can contribute insights into promoting responsible gaming services.
Social implications
The author offers insights for the game players, designers and developers, service providers and policymakers to promote a healthy gaming culture.
Originality/value
Through this research, the author advances the understanding of gaming as a service by illuminating value co-creation and co-destruction within an interconnected gaming service ecosystem through the lens of TSR. Such understanding empowers businesses to prioritise consumer welfare in their decision-making and practices.

Abstract
In this chapter, we seek to bring greater attention to language-based stigma at work and how it affects employees speaking English as their second language. We integrate research findings across multiple disciplines, including management, psychology, linguistics, education, and business ethics, identifying three major themes and knowledge gaps in this research domain. Based on the multidisciplinary knowledge integration, we suggest six promising future directions for organizational and business ethics scholars to pursue. We call for more empirical research focusing on how language-based stigma may harm nonnative English speakers (NNESs) with and without actual mistreatment or discrimination at work and how organizations may intervene to support NNESs. We hope our chapter will spark conducive conversations about mitigating language-based stigma in the workplace.

Abstract
Purpose
The purpose of this study was to validate the feasibility of the proposed microstructure-based model by comparing the simulation results with experimental data. The study also aimed to investigate the relationship between the orientation of graphite flakes and the failure behavior of the material under compressive loads as well as the effect of image size on the accuracy of stress–strain behavior predictions.
Design/methodology/approach
This paper presents a microstructure-based model that utilizes the finite element method (FEM) combined with representative volume elements (RVE) to simulate the hardening and failure behavior of ferrite-pearlite matrix gray cast iron under uniaxial loading conditions. The material was first analyzed using optical microscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD) to identify the different phases and their characteristics. High-resolution SEM images of the undeformed material microstructure were then converted into finite element meshes using OOF2 software. The Johnson–Cook (J–C) model, along with a damage model, was employed in Abaqus FEA software to estimate the elastic and elastoplastic behavior under assumed plane stress conditions.
Findings
The findings indicate that crack initiation and propagation in gray cast iron begin at the interface between graphite particles and the pearlitic matrix, with microcrack networks extending into the metal matrix, eventually coalescing to cause material failure. The ferritic phase within the material contributes some ductility, thereby delaying crack initiation.
Originality/value
This study introduces a novel approach by integrating microstructural analysis with FEM and RVE techniques to accurately model the hardening and failure behavior of gray cast iron under uniaxial loading. The incorporation of high-resolution SEM images into finite element meshes, combined with the J–C model and damage assessment in Abaqus, provides a comprehensive method for predicting material performance. This approach enhances the understanding of the microstructural influences on crack initiation and propagation, offering valuable insights for improving the design and durability of gray cast iron components.

Abstract
Purpose
This study aims to further refine the model, explore the influence of cutting parameters on the machining process, and apply it to practical engineering to improve the efficiency and quality of titanium alloy machining.
Design/methodology/approach
This paper establishes a comprehensive thermo-mechanical fully coupled orthogonal cutting model. This paper aims to couple the modified Johnson–Cook constitutive model, damage model and contact model to construct a two-dimensional orthogonal cutting thermo-mechanical coupling model for high-speed cutting of Ti6Al4V. The model considers the evolution of microstructures such as plastic deformation, grain dislocation rearrangement, dynamic recrystallization, as well as stress softening and hardening occurring continuously in Ti6Al4V metal during high-speed cutting. Additionally, the model incorporates friction and contact between the tool and the workpiece. It can be used to predict parameters such as cutting process, cutting force, temperature distribution, stress and strain in titanium alloy machining. The study establishes the model and implements corresponding functions by writing Abaqus VUMAT and VFRICTION subroutines.
Findings
The use of different material constitutive models can significantly impact the prediction of the cutting process. Some models may more accurately describe the mechanical behavior of the material, thus providing more reliable prediction results, while other models may exhibit larger deviations. Compared to the Tanh model, the proposed model achieves a maximum improvement of 8.9% in the prediction of cutting force and a maximum improvement of 20.9% in the prediction of chip morphology parameters. Compared to experiments, the proposed model achieves a minimum prediction error of 2.8% for average cutting force and a minimum error of 0.57% for sawtooth parameters. This study provides a comprehensive theoretical foundation and practical guidance for orthogonal cutting of titanium alloys. The model not only helps engineers and researchers better understand various phenomena in the cutting process but also serves as an important reference for optimizing cutting processes.
Originality/value
The originality of this research is guaranteed, as it has not been previously published in any journal or publication.

Abstract
Purpose
The purpose of this study is to develop a new protective coating formulation for industrial use, using new eco-friendly succinimide linseed oil resin.
Design/methodology/approach
Epoxidized linseed oil and N-(4-hydroxy phenyl) succinimide are reacted to create succinimide-modified epoxy (SIE) compounds. The synthesized compound was confirmed by different analyses, gas chromatography, Fourier transform infrared, proton nuclear magnetic resonance and scanning electron microscopy. The prepared compound has been blended with a primer paint formulation, then their physical and mechanical properties have been studied. Density function theory is used to calculate Frontier molecular orbital including highest occupied molecular orbital and least unoccupied molecular orbital to indicate the charge transfer from molecule to biological media and molecular electrostatic potential map was used to indicate the chemically reactive zone suitable for drug action.
Findings
The results of the paint formulation confirmed their best performance and provided good mechanical properties and high chemical and corrosion resistance.
Research limitations/implications
Resin compounds are the most used antimicrobial additives. Other functionalities of these compounds, such as corrosion inhibitors, might be studied to see if they are suited for these applications.
Practical implications
Because of the efficiency of the SIE when incorporated with primer, paint against microbial has also been examined in silico using the docking study which contributed to the analysis of their protein binding. This type of epoxy compound is environmentally friendly and can be used as a biocide with different paint formulations. As a result, paint compositions including this compound as additives can be used as dual-purpose paint and for a variety of industrial applications.
Originality/value
This research demonstrates how a low-cost paint composition based on synthesized SIE compounds may be used as a dual-function paint for industrial use.

Abstract
Purpose
This study aims to explore how a postmodern tribe enacts and re-interprets ideologies as a part of consumers’ collective experience, to enhance our understanding of consumer communities in conjunction with ideological capacities.
Design/methodology/approach
The community of “presenteers” is conceptualized as a self-organized tribe with heterogeneous components that generate capacities to act. Netnographic observation was conducted on 18 presenteer accounts and lasted around six months. Real-time data were collected by taking screenshots of the posts and stories that these users created and publicly shared. Data were analysed by adopting assemblage theory, combining inductive and deductive approaches. Firstly, a qualitative visual-textual content analysis of the tribe’s defining components was conducted. Then, the process continued with the thematic analysis of the ideological underpinnings of the tribe’s enactments.
Findings
Findings shed light on the ways in which consumer communities interpret the entanglement of religious, political, and cultural ideologies in shaping their experiences. In the case of the presenteers tribe, findings reflect a novel ideological interplay between neo-Ottomanism, post-feminism and consumerism.
Research limitations/implications
The study offers a deep dive into a unique tribe that is being organized around the consumer-created practice of “presenteering” and investigates consumer communalization in alignment with the ideological turn in culture-oriented interpretative research on consumers, consumption, and markets. This exploration helps to bridge the research on the communalization of consumers with the recent discussions of ideology in the postmodern market.

Abstract
This chapter is born out of concern about the perception of the physical and symbolic place of the live-in housekeeper, both in socioeconomic, and historical terms, as well as the architectural and social dynamics of the home. An intersectional and teleological analysis of the intrinsic devaluation of paid social reproduction work is carried out, based mainly on gender, race, and class inequalities. Ultimately, the chapter tries to locate the position in which the maid finds herself in the domestic environment, both in family relationships and in the symbolism inherent to the concept of the maid’s room. Based on sociological, philosophical, and anthropological analysis, the ambiguous place of domestic workers becomes clearer, promoting a reflection on the very concept of family and household. Thus, the chapter proposes to achieve a hermeneutic dive into the experience of this working class, revealing a hierarchical system beyond the socioeconomic, but above all, of their subjectivities.

Abstract
Purpose
Surface quality and porosity significantly influence the structural and functional properties of the final product. This study aims to establish and explain the underlying relationships among processing parameters, top surface roughness and porosity level in additively manufactured 316L stainless steel.
Design/methodology/approach
A systematic variation of printing process parameters was conducted to print cubic samples based on laser power, speed and their combinations of energy density. Melt pool morphologies and dimensions, surface roughness quantified by arithmetic mean height (Sa) and porosity levels were characterized via optical confocal microscopy.
Findings
The study reveals that the laser power required to achieve optimal top surface quality increases with the volumetric energy density (VED) levels. A smooth top surface (Sa < 15 µm) or a rough surface with humps at high VEDs (VED > 133.3 J/mm3) can serve as indicators for fully dense bulk samples, while rough top surfaces resulting from melt pool discontinuity correlate with high porosity levels. Under insufficient VED, melt pool discontinuity dominates the top surface. At high VEDs, surface quality improves with increased power as mitigation of melt pool discontinuity, followed by the deterioration with hump formation.
Originality/value
This study reveals and summarizes the formation mechanism of dominant features on top surface features and offers a potential method to predict the porosity by observing the top surface features with consideration of processing conditions.

Abstract
This chapter will develop an understanding of what the logical conclusion of having English football clubs primarily existing as businesses: namely, those instances where clubs are treated not as community institutions but as any other business with set assets that can be disposed of at a profit. There is an unfortunate history of clubs being owned based on the value of the assets they possess (such as their stadium or training), a trend that has only seemed to accelerate in recent decades. The various forms asset stripping takes can be explored by examining what happened to clubs like Blackpool FC and Wimbledon FC, as well as many others. This chapter is an exploration of what happens when the entity that fans assume is something more than a business is dismantled for profit, the harshest of reality checks, and a reminder that football clubs in these contexts are little more than business assets.
