To consider the problem of outsourcing warranty repairs to outside vendors when items have priorities in service.

The repair allocation problem is formulated as a convex minimum‐cost network flow problem and solve it by the successive shortest path algorithm. The computation issues involved with the problem are also discussed.

Examples are provided to illustrate the cost benefits achieved due to the priority structure.

The research uses a closed static allocation model. Future research efforts can expand our model by considering a dynamic allocation method or an open population model.

The paper can be a valuable resource to warranty managers who make decisions regarding the negotiations of warranty contracts and the allocation of items to outside repair vendors.

A warranty manager can apply our results to receive insight on the value of giving priority in service to special customers. In addition, resource allocation problems with an objective structure similar to our application can be efficiently solved using our algorithm.

This paper aims to investigate small and medium-sized upstream suppliers' and downstream distributors' understandings of supply chain finance (SCF) arrangements and their decisions to adopt such schemes.

In this paper grounded theory-informed methods are employed, involving 56 in-depth interviews with informants from small and medium-sized enterprises (SMEs), banks and subject experts in the United Kingdom (UK) and Thailand. A category structure for the data is developed. The findings are then examined systematically from both a transaction cost economics (TCE) and non-TCE perspective.

SME members made sense of SCF through a core distinction between dyadic and triadic SCF arrangements. The former maintains independence between physical and financial supply chains, whereas the latter causes them to be closely coupled or even entangled. The SCF adoption decisions of SMEs were based on a consideration of four related aspects: relationality, awareness, control and context. The authors demonstrate the limits of TCE in explaining the findings, leading to a proposed combined theory of the transactional and, importantly, non-transactional influences on how SMEs make decisions about SCF.

Focal firms wanting their SME suppliers and distributors to participate in triadic SCF (TSCF), i.e. reverse factoring and distributor finance, need to understand that transitioning to such schemes involves the unwinding of existing financing arrangements, which may be problematic for SMEs. Moreover, it is important to be aware of SMEs' concerns, such as about what accessing TSCF might signal to the focal firm about their financial health and about the potential loss of control that might result from entangling the physical and financial aspects of supply chains.

This paper unpack the perspectives of both SME suppliers and distributors of large focal firms in supply chains. These firms appear less concerned with the economic advantages (transaction costs) of SCF and more concerned with the relational consequences or non-transactional costs of participation in a TSCF arrangement. The dyadic-triadic distinction provides a new and meaningful way of categorising SCF mechanisms, which also broadens the service triads’ literature from a focus on outsourcing services for a focal firm's customers to outsourcing financing for its suppliers or distributors. The paper also addresses gaps identified by Gelsomino et al. (2016) regarding the need for a general theory of SCF, for empirically-based holistic studies of SCF applications, and a tool for selecting SCF mechanisms.

The buoyancy‐driven magnetohydrodynamic flow in a cubic enclosure was investigated by three‐dimensional numerical simulation. The enclosure was volumetrically heated by a uniform power density and cooled along two opposite vertical walls, all remaining walls being adiabatic. A uniform magnetic field was applied orthogonally to the gravity vector and to the temperature gradient. The Prandtl number was 0.0321 (characteristic of Pb–17Li at 300°C), the Rayleigh number was 10⁴, and the Hartmann number was made to vary between 0 and 2×10³. The steady‐state Navier–Stokes equations, in conjunction with a scalar transport equation for the fluid's enthalpy and with the Poisson equation for the electrical potential, were solved by a finite volume method using a purposely modified CFD code and a computational grid with 64³ nodes in the fluid. Emphasis was laid on the effects of increasing the Hartmann number on the complex three‐dimensional flow and current pattern.

Over the past two decades, the study of team resilience has evolved from focusing primarily on team performance to recognizing its importance in various aspects of team functioning, including psychological health, teamwork, and overall Well-Being. This evolution underscores the need for a broader, more inclusive understanding of team resilience, advocating for a shift from a narrow performance-centric view to a holistic perspective that encompasses the multifaceted impact of resilience on teams.

In advocating for this holistic perspective, this chapter reviews the extant literature, highlighting that resilience is not merely about sustaining performance but also about fostering a supportive, adaptive, and psychologically safe environment for team members. Significant areas for further exploration, including the nuanced nature of adversities teams face, the processes underpinning resilient behaviors, and the broad spectrum of outcomes resilience can influence beyond task performance are also discussed.

The chapter serves as a call to action for a more inclusive examination of how resilience manifests and benefits teams in organizational settings. The proposed shift in perspective aims to deepen understanding of team resilience, promoting strategies for building resilient teams that thrive not only in performance but in all aspects of their functioning.

The purpose of this study is to show the procedure, application and main features of the hybrid numerical-analytical approach known as generalized integral transform technique by using it to study magnetohydrodynamic flow of electrically conductive Newtonian fluids inside flat parallel-plate channels subjected to a uniform and constant external magnetic field.

The mathematical formulation of the analyzed problem is given in terms of a streamfunction, obtained from the Navier–Stokes and energy equations, by considering steady state laminar and incompressible flow and constant physical properties.

Convergence analyses are performed and presented to illustrate the consistency of the integral transformation technique. The results for the velocity and temperature fields are generated and compared with those in the literature as a function of the main governing parameters.

A detailed analysis of the parametric sensibility of the main dimensionless parameters, such as the Reynolds number, Hartmann number, Eckert number, Prandtl number and electrical parameter, for some typical situations is performed.

This study aims to examine the applicability of Hartmann et al.’s (2018) service ecosystem framework to the day-to-day management of the modern sales force. The authors provide a review of the framework, acknowledging its strengths, while also indicating areas for advancement. The authors conclude with recommendations to the framework and indicate opportunities where future research could advance sales theory.

A review of the theoretical underpinnings of the service ecosystem framework is weighed against the established roles and responsibilities of the modern sales force in the literature.

The ability of the framework to capture the multi-level, multi-actor and dynamic aspects of sales represents an improvement in the conceptualization of selling is critical. Suggestions around the refinement for meso-level sales interactions and a more pliant application of service dominant-logic are offered.

The suggested extensions of the framework continue the advancement of novel theorization for the field of sales. Priorities for future research include consideration of ethical implications of the framework and formulations of new management strategies reflective of the broad and dynamic properties of the ecosystem conceptualization.

This paper provides managerial guidelines and implications tied specifically to the thick and thin crossing points and how they may impact employee decision-making.

To the best of the authors’ knowledge, this study is the first to pointedly examine the service ecosystem framework with respect to established principles of managing a modern sales force.

Across disciplines, researchers and practitioners employ decision tree ensembles such as random forests and XGBoost with great success. What explains their popularity? This chapter showcases how marketing scholars and decision-makers can harness the power of decision tree ensembles for academic and practical applications. The author discusses the origin of decision tree ensembles, explains their theoretical underpinnings, and illustrates them empirically using a real-world telemarketing case, with the objective of predicting customer conversions. Readers unfamiliar with decision tree ensembles will learn to appreciate them for their versatility, competitive accuracy, ease of application, and computational efficiency and will gain a comprehensive understanding why decision tree ensembles contribute to every data scientist's methodological toolbox.

The purpose of this paper is to study the effects of ion‐slip current and Hall current on the formation of longitudinal vortices in natural convection flow over a heated horizontal plate.

The criterion on the position marking on the onset of longitudinal vortices is defined in the present paper. The results show that the onset position characterized by the Grashof number depends on the Prandtl number, the Reynolds number, the wave number, the Hall parameter, the ion‐slip parameter, and the Hartmann number.

The flow becomes more stable as the magnetic field increases. However, the destabilizing effect is found on the flow when the Hall and ion‐slip currents are presented.

The standard method of linear stability model is applied, with terms higher than first order in disturbance quantities being neglected.

The problem of MHD natural convection flow with Hall and ion‐slip currents has many important engineering applications, e.g. power generators, Hall accelerators and flows in channels and ducts.

This study is to check the validity of the assumptions that the conditions of Hall and ion‐slip currents can be ignored.

Recent accounting research has connected the coercive and enabling types of formalisation (C/E) (Adler and Borys, 1996) with the distinction between diagnostic and interactive controls (D/I) proposed by Simons (1995, 2000) to tackle research questions on complex control situations involving both the degree of employee autonomy and patterns of management attention. The diverse conceptual approaches used for connecting C/E and D/I have led to fragmentation in the literature and raise concerns about their conceptual clarity. In this paper, we assess the conceptual clarity of various forms of connection between C/E and D/I. Firstly, we conduct an in-depth content analysis of 59 recent papers, and inductively identify three points of conceptual ambiguity and divergence in the literature (namely, the perspective from which a phenomenon is studied; whether categories capture choices driven by design or by style-of-use; and the properties of control systems). We also observe that the literature proposes various forms of connection (i.e. coexistence, inclusion, and combination approaches). Secondly, we use the three detected points of ambiguity and divergence as assessment criteria, and evaluate the extent to which conceptual clarity is at risk under each form of connection. Based on this assessment, we provide guidelines to enhance the conceptual clarity of the connections between C/E and D/I, propose several research models, and indicate opportunities for future research in this area.

The present book chapter deals with the problem of dark tourism as well as the resilience forms of consumption in post-disaster context.

The turn of the century characterised a radical change in the forms of tourism consumption. New forms of tourism as dark or thana tourism have captivated the attention of scholars and journalists. This book chapter centres efforts in dillucidating what are the key factors that determine the formation of a dark site. The text is inspired in my own ethnographies in Cromañon, Argentina and the Ground Zero, US.

As Phillip Stone puts it, not all dark shrines or sites welcome tourists. While some sites are reluctant to mass tourism, others are mainly organised around the figure of the tourist. La Republica de Cromañón is a night club where in a fire died 194 young. The site is today refurbished as a sanctuary to remind the victims. At a closer look, there is a tension between stakeholders at the time of promoting dark tourism in Cromañón. In the opposite the ground zero is fully designed to be visited by thousands tourists.

The originality of this research consists in the contraposition of two study cases which answer the question to what extent dark tourism is desired by locals. The findings lay the foundations towards the specialised literature in dark tourism studies. We discuss critically the nature of thanatopsis.
