Abstract
Provides a comprehensive, critical review of failure prediction with cash flow information since Beaver (1966); and tabulates the methods and cash flow variables used, and the results produced. Describes the literature as “inconsistent and inconclusive” and discusses possible reasons why, e.g. the measurement and diversity of cash flows, lack of model validation, multicollinearity etc. Points out the importance of cash to solvency and dividend payouts; and the limitations it places on creative accounting. Summarizes the reasons for previous inconsistencies and considers possibilities for further research.

Abstract
Purpose
The purpose of this manuscript is to study the vibration characteristics of the spherically symmetric solid and hollow spheres poised of a homogeneous thermoelastic material, based on the three dimensional coupled thermoelasticity.
Design/methodology/approach
In this paper, matrix Fröbenius series solution is used to derive the frequency equations, for the field functions. Results have been applied on rigidly fixed boundary conditions.
Findings
The main finding of this paper is that the frequency of vibration of spherically symmetric sphere (structure is independent of theta and phi) increases with the increase of radius, for solid spheres and for hollow spheres with thickness to mean radius ratio. Deformation in the given materials increases with thickness to mean radius ratio of the hollow sphere.
Originality/value
A numerical simulation has been done with the help of functional iteration method for solid and hollow thermoelastic spheres made of zinc and poly methyl meth acrylate materials for different boundary conditions. The computer simulated results in contempt of frequency, damping of vibration modes and displacement have been obtained graphically and compared with the existed results.

Abstract
Purpose
The purpose of this paper is to investigate the impact of fairness concerns of the retailer on the pricing policies of the supply chain partners, their individual profits, and the overall performance of a dual-channel supply chain composed of one manufacturer and one retailer. First, the authors model the dual-channel supply chain under retailer’s fairness concern. Second, the authors derive the optimal pricing policies of the channel members. Third, the authors analyze the effects of retailer’s fairness and bargaining power on the pricing strategies and profit functions of the dual-channel supply chain system.
Design/methodology/approach
The authors adopt the manufacturer-led Stackelberg game theoretic framework, where the dominant manufacturer’s pricing decisions are based on the retailer’s pricing decision. The paper considers Nash bargaining solution as the fairness reference point to formulate the utility function of the fair-retailer. The paper uses this approach because it endogenously accounts for the competitive power and cooperative contribution of the channel members when they interact.
Findings
The authors find that the retailer’s fairness concerns are not always beneficial for its better performance. If the retailer is moderately sensitive towards its fairness, it will positively influence its performance. However, if the fairness concern becomes too high then it will negatively impact the retailer’s performance because it results in customers’ migration towards direct online channel for buying the products. In addition, if the retailer’s fairness concerns are mild, the manufacturer’s prices will decrease in retailer’s bargaining power, which is opposite otherwise.
Originality/value
The authors use Nash bargaining solution model as the fairness reference in the context of dual-channel supply chain, which is comparatively a recent approach and has been used independently from dual-channel supply chain system.

Abstract
Purpose
Circular economy (CE) is a structured model of production and consumption involving sharing, leasing, reusing, recycling, repairing and refurbishing existing products or materials sustainably. Despite the numerous benefits of CE adoption, the construction and demolition (C&D) sector still struggles to comprehensively understand, integrate and adopt this approach. This study provides a comprehensive analysis of CE within the C&D sector and proposes a structured conceptual framework for an effective construction and demolition waste management (CDWM) program.
Design/methodology/approach
A systematic literature review (SLR) was conducted using the “Preferred Reporting Items for Systematic Reviews and Meta-Analyses” (PRISMA) framework to search for articles across three databases: Scopus, Web of Science and EBSCO. EndNote software and Excel spreadsheets were used to analyze and synthesize the articles up to 2024. A total of 102 articles were included in the study. Various key facets of the CE in CDWM, including barriers and mitigation actions, enablers, tools and techniques, benefits, strategies and frameworks, have been thoroughly reviewed and analyzed for the C&D sector to understand their nature and effectively adopt the CE approach in CDWM operations.
Findings
The findings provide a comprehensive analysis of different facets of CE in CDWM and a structured conceptual framework for the effective adoption of CE. This will contribute to improving the management of CDWM in the C&D sector. The outcomes offer a comprehensive knowledge base of CE in CDWM to managers, planners, decision-makers, stakeholders and researchers, enabling effective deployment.
Practical implications
This study offers a substantial knowledge base to researchers by examining various key facets of CE in CDWM, aiding further exploration of research in the same domain. Additionally, it assists C&D managers, planners, stakeholders and decision-makers by furnishing a structured conceptual framework of CE, thereby enhancing effective implementation. Furthermore, this study supports society by providing a pathway to improve C&D waste circularity through the execution of CE.
Originality/value
This study is the first to comprehensively review the various facets of CE from a CDWM perspective and to propose a structured conceptual framework for the effective adoption of CE in the C&D sector. Additionally, it not only advances theoretical knowledge of CE adoption in the CDWM field but also provides practical guidance to stakeholders on how to implement a comprehensive CE approach to enhance C&D waste circularity.

Abstract
In a pandemic framework (COVID-19), this chapter explores the impact of the global economy and socio-cultures concerning three axes: recreational, tourism, and hospitality. Although we slowly see an economic revival, it is well known that this sector of study is very susceptible to being affected by the context of nations. Following restrictions and measures taken by governments around the world to reduce the number of cases of coronavirus infections, many nations closed their borders, affecting international travel and by 2020 tourism had been reduced to the near cessation of operations due to the imminent fear of this poorly studied disease, and the service sector was negatively affected. It should be added that, according to the World Tourism Organization's projections, a decrease of between 20 and 30% is forecast for 2020 compared to the previous year.

This study contributes to the understanding of the health effects of pesticides exposure and of how pesticides have been and should be regulated.
Abstract
Purpose
This study contributes to the understanding of the health effects of pesticides exposure and of how pesticides have been and should be regulated.
Design/methodology/approach
This study presents literature reviews for the period 2000–2013 on (i) the health effects of pesticides and on (ii) preference valuation of health risks related to pesticides, as well as a discussion of the role of benefit-cost analysis applied to pesticide regulatory measures.
Findings
This study indicates that the health literature has focused on individuals with direct exposure to pesticides, i.e. farmers, while the literature on preference valuation has focused on those with indirect exposure, i.e. consumers. The discussion highlights the need to clarify the rationale for regulating pesticides, the role of risk perceptions in benefit-cost analysis, and the importance of inter-disciplinary research in this area.
Originality/value
This study relates findings of different disciplines (health, economics, public policy) regarding pesticides, and identifies gaps for future research.
