The prolonged training time of the neural network (NN) has sparked considerable debate regarding their application in the field of optimization. The purpose of this paper is to explore the beneficial assistance of NN-based alternative models in inductance design, with a particular focus on multi-objective optimization and uncertainty analysis processes.

Under Gaussian-distributed manufacturing errors, this study predicts error intervals for Pareto points and select robust solutions with minimal error margins. Furthermore, this study establishes correlations between manufacturing errors and inductance value discrepancies, offering a practical means of determining permissible manufacturing errors tailored to varying accuracy requirements.

The NN-assisted methods are demonstrated to offer a substantial time advantage in multi-objective optimization compared to conventional approaches, particularly in scenarios where the trained NN is repeatedly used. Also, NN models allow for extensive data-driven uncertainty quantification, which is challenging for traditional methods.

Three objectives including saturation current are considered in the multi-optimization, and the time advantages of the NN are thoroughly discussed by comparing scenarios involving single optimization, multiple optimizations, bi-objective optimization and tri-objective optimization. This study proposes direct error interval prediction on the Pareto front, using extensive data to predict the response of the Pareto front to random errors following a Gaussian distribution. This approach circumvents the compromises inherent in constrained robust optimization for inductance design and allows for a direct assessment of robustness that can be applied to account for manufacturing errors with complex distributions.

This study aims to introduce and define the concept of phygital brand community (PBC). It discusses the potential conflicts that can arise from engaging in multiple PBCs and propose an enriched netnographic methodological approach to explore the role of PBC engagement overlap and its influence on the phygital experience.

Following a critical analysis of the inherent limitations of netnographic methodological approaches in the context of PBCs, this study develops an enriched netnographic research protocol that accounts for the challenges of engagement overlap among PBCs.

This study proposes two methods of analysis, namely, “participatory netnography” and “witness netnography,” which are derived from a mixed-methodology approach that integrates elements of netnography.

The findings of this study underscore the requisite methodological refinements imperative for enhancing netnographic analysis, particularly in its application for a better comprehension of individual behaviors within the realm of PBCs. In pursuit of this objective, the identified adjustments encompass ethical considerations, evaluation methods and their application in a digital milieu, where intricate mechanics and technologies frequently elude conventional methodologies.

In this study, the authors present a novel conceptualization of PBCs, highlighting their role and development, as well as the challenges they pose. To adequately capture the impact of PBC engagement overlap, the authors propose the need for an enriched mixed-methodological approach.

This study aims to develop a conceptual framework for the role of chief financial officer (CFO) in an ever-changing environment. As previous research focused on responding to specific crises, there have been theoretical and practical gaps in the role of CFO. The study's goal is to fill a critical gap by developing a comprehensive and integrated set of roles to assist the CFO in a constantly changing environment.

Using a grounded theory approach, semi-structured interviews and observations were conducted with 21 CFOs from various industries in Thailand, including foreign multinational corporations and domestic companies with international operations. CFOs were asked how they frame their roles in the face of an ever-changing environment and how they prepare for the future.

The iCFO model is developed, which identifies the critical “core” roles of the CFO in securing the business foundation, as well as the “future opportunities” roles that function as growth engines for long-term business strength. The research delves into the importance of integrity, ethical mindset and corporate governance in the role of the CFO. The iCFO model is designed to help guide future research and provide practical applications for CFOs in both domestic and international contexts. The term “core” refers to the CFO’s primary responsibilities, which include driving profitability, managing risks and optimizing business performance. The “future opportunities” component focuses on the roles that CFOs can play in strengthening the future of business by optimizing investment efficiency, driving digital transformation and being the CEO’s business partner. The findings also emphasized “integrity,” which must encompass all decisions, actions or recommendations made by the CFO.

The study offers unique perspectives on an emerging economy, providing new insights. Through interviews with 21 CFOs, it contributes empirical evidence on the development of roles in accounting and finance, emphasizing good governance practices. The findings highlight the integrated role of the CFO and their self-reflection on their value within the company. Significantly, the study's implications are relevant and applicable to a global audience, particularly in developing economies that prioritize growth. Future studies could incorporate integrated thinking into the iCFO model to address social, environmental and economic factors, making it more universally relevant. Additionally, exploring the adoption of the chief value officer context in developing markets could enable CFOs to expand their focus beyond financial metrics, embracing a comprehensive approach to value creation. By integrating these concepts into the iCFO model, CFOs can effectively drive sustainable and impactful business outcomes on a global scale.

This study aims to explore the factors influencing the bottom of the pyramid (BOP) consumers’ adoption and usage intention towards mobile payment (m-payment) to achieve financial inclusion and sustainable development goals.

A qualitative research design is used to explore the enablers and inhibitors that influence BOP consumers’ m-payment adoption and usage intention. To collect the qualitative responses, semi-structured in-depth interviews with BOP respondents were conducted. The thematic analysis using the text mining technique will be used to analyse qualitative data for exploring the predominant factors affecting m-payment adoption intention and usage.

The results suggested awareness, social influences and self-efficacy as crucial enablers and privacy and security risks and vulnerability concerns as crucial inhibitors towards m-payment adoption and usage.

As a novel contribution to the BOP, financial inclusion, sustainable development goals and m-payment literature, this study unfolds several unknown perceived benefits and perceived sacrifices that influence the BOP consumers’ m-payment adoption intention and usage. The study’s findings help the government and banks formulate and implement strategies to achieve financial inclusion among BOP consumers.

The aim of this paper is to explore the possibility of using the Define-Measure-Analyze-Improve-Control (DMAIC) cycle, process mining (PM) and multi-criteria decision methods in an integrated way so that these three elements combined result in a methodology called the Agile DMAIC cycle, which brings more agility and reliability in the execution of the Six Sigma process.

The approach taken by the authors in this study was to analyze the studies arising from this union of concepts and to focus on using PM tools where appropriate to accelerate the DMAIC cycle by improving the first two steps, and to test using the AHP as a decision-making process, to bring more excellent reliability in the definition of indicators.

It was indicated that there was a gain with acquiring indicators and process maps generated by PM. And through the AHP, there was a greater accuracy in determining the importance of the indicators.

Through the results and findings of this study, more organizations can understand the potential of integrating Six Sigma and PM. It was just developed for the first two steps of the DMAIC cycle, and it is also a replicable method for any Six Sigma project where data acquisition through mining is possible.

The authors develop a fully applicable and understandable methodology which can be replicated in other settings and expanded in future research.

As research emerged in terms of how narcissism, a negative or dark trait, has been found to be constructive in enhancing entrepreneurial behaviour, there are mixed results regarding the significance of narcissism in the field of entrepreneurship. Additionally, this previous research has mostly been conducted on student or nascent entrepreneur samples within developed economies. Therefore, the purpose of this paper is to explore how narcissistic traits of established entrepreneurs in an emerging economy context infuence their entrepreneurial behaviour both positively and negatively.

Gioia methodology was applied in the qualitative study by means of in-depth interviews, which allowed for the unpacking of narcissistic traits among established entrepreneurs in South Africa. Four themes emerged from the data, and included insights related to entrepreneurial experience influencing behaviour; business growth linked to personal development; opportunity identification versus loss; and identity separation in relation to authentic identity versus an entrepreneurial identity.

The findings of the paper contribute to creating an understanding of how to hone individual narcissistic traits for positive influences that develop entrepreneurs while also contributing to their business development, opportunity realization and identity. In addition, the findings highlighted a separation between established entrepreneurs’ authentic personality and the inputs that end up resulting in the entrepreneurial personality.

This paper highlights the possibility of narcissism functioning as a business process involved in entrepreneurship rather than a necessary personality trait. An interesting dynamic contributed to what seems to be a constant battle between the authentic identity and the entrepreneur identity, gaining deeper insight surrounding established entrepreneurs’ experiences to survive and, more importantly, thrive as entrepreneurs.

Applying signaling theory to Schein’s organizational culture framework, this study aims to explain how restaurants communicate that their establishments value wine through multiple cultural attributes.

A phenomenological research design was adopted to conduct three focus groups with 14 restaurateurs about wine culture. Conversational analysis with Straussian coding was used.

A comprehensive definition of wine culture was provided, and five factors emerged that signal the presence of a wine culture. A wine presence includes a wine list, marketing efforts, community involvement and restaurant aesthetics. Employee traits are defined by individual attributes, communications skills and overall knowledge (training). Restaurant identity reflects the cultural alignment and customer relationship expectations set forth by ownership. Organizational structure reflects a restaurant’s hierarchy within which an individual or department is afforded the freedom to invest in wine. Future alignment reflects generational differences and trends in wine preferences and consumption.

Researchers are provided a wine-culture definition and framework for wine research. Restaurants can use the study’s findings to formulate strategies for establishing a wine culture.

This study provided a framework for restaurateurs who wish to be known for wine to implement. Researchers and restaurateurs may facilitate communication between guests, staff and an organization regarding wine as a means of creating a competitive advantage.

This study problematizes the prevailing normative and managerial-dominated view of self-initiated employee ambassadorship on social media from a power perspective. The aim is to provide a more nuanced and critical understanding of the negative aspects of this phenomenon.

The empirical material encompasses qualitative interviews with employees from 14 organizations and Foucault’s concept of disciplinary discursive power to analyze which and how discourses exert power over employee communication on social media and what role visibility plays in it.

This study indicates that employee ambassadors’ social media communication is governed by two discourses that create complex tensions, where ambassadors constantly must negotiate between self-branding requirements and an authenticity paradox. These tensions intensify through visibility on social media, where employees strategize and situationally silence their communication through self-monitoring and self-surveillance practices. Conclusively, the findings also outline the need for further critical research to offer a deeper understanding of power relations that influence the communication practices of organizational members.

The paper contributes to a more nuanced understanding of self-initiated employee ambassadorship on social media and highlights disciplinary power relations that go beyond organizational borders.

The findings underscore that organizations need to address the critical aspects of self-initiated employee ambassadorship and act as facilitators to support employees in their navigation process.

This paper contributes a new critical power perspective on employee ambassadorship on social media.

This study aims to investigate the influence of ChatGPT, an AI-based chatbot, on the digital learning experience of students at Mzumbe University.
