The purpose of this paper is to study the thermal behavior of radial porous fin surrounded by water-base copper nanoparticles under the influence of radiation.

In order to optimize the response variable, the authors perform sensitivity analysis with the aid of response surface methodology (RSM). Moreover, this study enlightens the applications of artificial neural networks (ANN) for predicting the temperature gradient. The governing modeled equations are firstly non-dimensionalized and then solved with the aid of Runge–Kutta fourth order together with the shooting method in order to guess the initial conditions.

Numerical results are analyzed and presented in the form of tables and graphs. This study reveals that the temperature of the fin is decreasing as the wet porous parameter increases (m₂) and the temperature for 10% concentration of nanoparticles are higher than 5 and 1%. Physical parameters involved in the study are analyzed and processed through RSM. It is come to know that sensitivity of temperature gradient to radiative parameter (Nr) and convective parameter (Nc) is positive and negative to dimensionless ambient temperature (θ_a). Furthermore, after ANN training it can be argued that the established model can efficiently be used to predict the temperature gradient over a radial porous fin for the copper-water nanofluid flow.

To the best of our knowledge, only a few attempts have been made to analyze the thermal behavior of radial porous fin surrounded by copper-based nanofluid under the influence of radiation and convection.

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 sex work research field has expanded significantly in recent years, and a myriad of studies have highlighted diverse forms of injustice that sex workers endure. Sex workers are a marginalised and criminalised population and thus researchers have an ethical responsibility to undertake research that challenges existing social conditions and can help support sex worker-led campaigns for change. But what does ‘making a difference’ mean in the context of sex work research and what factors may constrain the extent to which this can be achieved? In this chapter, I explore the promise and pitfalls of undertaking politically engaged, activist research on sex work. I do so by reflecting on my experience as a researcher in the New Zealand context. The aim of this chapter is to unpack the challenges of undertaking research for social change and to explore the possibilities for strengthening the impact of research in this ideologically charged area.

To contextualise the contributions in this section, we present some data on growing up in South Asian societies. It is important to consider the fundamental diversity of conditions in which children and youth live. We suggest some theoretical terms that are helpful in this regard and preview the contributions against this background. The studies on which the contributions are based impressively document the striking inequality in this region.

The purpose of this chapter was to explore how the values of higher education institutions, and ultimately society, are conveyed through the curriculum of an institution. The arguments for focusing on a liberal education grounded in critical thinking are highlighted and then compared to the growing trend of occupational education being the central focus of a college education. The need to understand populist thinking in particular is aligned with the social responsibility that educational institutions carry in their charters. This means that the students and parents who pay tuition for their education want something to show for their investment, namely a level of compensation and employment that is perceived to be correlated with the expense of the degree. The competing views of education and training are then considered in a global context, noting the interconnectedness of the intellectual and business community around the globe. This chapter concludes by highlighting the importance of education and its impact on cultural understanding and engagement as a value, especially calling upon public policymakers to keep higher education leaders in check as they develop plans and expectations for their institutions.

Based on literature providing evidence that Afrocentric hairstyles (e.g. afros, braids, dreadlocks) of Black women working in professional settings are often associated with negative stereotypes and biases regarding competency and professionalism, this chapter examines the extent to which these biases may be influencing the hairstyle choices of Black women employed in higher education. While academic workplaces tend to be more flexible and informal than non-academic settings, we found many Black women in higher education are, nonetheless, choosing to wear Eurocentric hairstyles. However, choice of hairstyle was influenced by academic discipline, type of institution and level in the university hierarchy.

This study aims to investigate the growing use of financial metrics (such as return on investment [ROI]) to measure performance and evaluate human capital (HC) investments.

The research employed an embedded case study approach, examining how one ROI approach was applied to evaluating HC investments, across three sectors (corporate, public health and international development).

Three major findings emerged in this study: First, interpretations of ROI can lead to ambiguity during implementation. ROI is interpreted trichotomously – metaphorically, as a desire for value; literally, as a metric; and procedurally, as a method for planning and evaluating HC investments. Second, understanding, measuring and tracking the domains of people performance (cognitive, affective and psychomotor) is vital to evaluating the impact of HC investments because this is where the change in behavior occurs. Third, although the logic model measures the change in process following an intervention (input-activity-output-outcome-impact), other approaches measure the change in behavior of people in the intervention (people performance).

These findings provide clarity for practitioners about challenges when applying ROI.

This is the first study to explore how the ROI financial metric is applied in a new domain by first examining its interpretation. It elucidates the use of ROI in practice, as well as the different purposes of key ROI approaches.

This study aims to explore to what extent stakeholder engagement affects the sustainability reporting (SR) process and if it succeeds in facilitating the encounter between demand and supply of accountability, as well as the main challenges of this practice, by focusing on a crucial and under-investigated public sector area, the judicial system.

The study adopts an action research (AR) approach. Specifically, it focuses on a specific phase (i.e. stakeholder engagement) of the broader project that was carried on from 2019 in an Italian Public Prosecutor’s Office. Data were collected from multiple sources, i.e. written notes and reports gathered during meetings, the survey administered to stakeholders and the published sustainability reports.

Stakeholder engagement may be a valuable and effective tool for improving the level of accountability, as it increases the responsiveness of SR to the informative needs of stakeholders. However, the study also highlights some critical points that must be addressed to exploit this fully. Among these is the need to act upstream of the process by working on an accounting system that goes beyond the economic dynamics and can effectively answer the accountability demand.

The study contributes to theoretical and empirical knowledge by exploring a topic and a public sphere still limited investigated, i.e. the stakeholder engagement in sustainability in the judicial sector. The AR approach also presents some originality points, as it is low widespread in management and accounting literature.

Stakeholder capitalism has been proposed as an alternative way of thinking about business purpose and value creation. However, stakeholder capitalism can only work as an alternative model of business if all stakeholders and their interests are visible to and taken seriously by managers. The purpose of this paper is to untangle the challenges that invisible, marginalized and powerless stakeholders pose for theorizing about stakeholder capitalism.

This paper is conceptual. The authors first briefly outline the promise of stakeholder capitalism for addressing pressing questions about value creation and stakeholder welfare. The authors then conceptualize stakeholder invisibility as the outcome of a particular stakeholder being both powerless and marginal through the prism of moral intensity theory and one of its elements: proximity. This study discusses the ways in which managers can make invisible stakeholders more visible in their decision-making.

For managers truly to manage for stakeholders, as anticipated by stakeholder capitalism, all stakeholders and stakeholder interests must be visible to them. This study analyzes why sometimes they are not, how they can be made more visible and why stakeholder visibility matters for stakeholder capitalism. This study proffers three principles for business practice: ethical commitments to reduce stakeholder invisibility, analyses of business strategies to surface the contributions of marginalized and invisible stakeholders and taking rights seriously.

This study provides a new perspective on stakeholder capitalism by linking the challenge in operationalizing it to the problems of stakeholder invisibility and marginality.

This study aims to develop a comprehensive, theoretically grounded framework of customer-to-customer interaction (CCI) management, by revisiting three older services marketing models: the servuction model, the services marketing triangle and the services marketing pyramid.

Noting the lack of theoretical frameworks of CCI management, this study adopts a problematization approach to identify foundational services marketing models, question their underlying assumptions, develop an alternative conceptual framework and evaluate its adequacy for CCI management, on the basis of a systematic literature review and content analyses.

By revisiting the assumptions underlying three relevant models in the light of the present-day, technology-infused service environment, this study proposes a four-triangle CCI management framework encompassing four specific modes of CCI management: managerial decisions by the firm; frontline employees; the design of the physical environment; and technology. Furthermore, this study emphasizes the triadic relationships involving the focal customer, other customers and the four modes of CCI management. Building on these findings, this study concludes with an extensive research agenda.

To the best of the authors’ knowledge, this study represents the first scholarly effort in services marketing literature to provide a comprehensive, theoretically grounded framework of CCI management. With its basis in foundational models, the new framework is well-suited to address future challenges to service marketplaces too.
