Abstract
Purpose
This study examines how substantive and/or associative claims about the local origin of organic products moderate the determinants and consequences of a grocery retailer’s corporate social responsibility (CSR).
Design/methodology/approach
An experiment with four different conditions – no claim, substantive claim (i.e. number of kilometres), associative claim (i.e. photograph of the producer) and a combination of substantive and associative claims – was carried out in a laboratory store in France with 249 consumers who were randomly divided into four independent samples (a between-subjects design). To analyse the data, partial least squares structural equation modelling was mobilised using XLSTAT (2022) software.
Findings
The study indicates that using claims about the local origin of organic products via in-store signage is an appropriate tool for grocery retailers. For the three types of claims considered, the ethics of the offering influences the retailer’s CSR, which has an indirect impact on consumers’ actual purchases of local organic products via two routes: trust and affective commitment and trust and preference for the retailer. However, grocery retailers should favour a combination of substantive and associative claims to create a stronger impact on purchases.
Originality/value
This research extends the use of substantive and associative claims to sustainable products.

Abstract
Purpose
This article aims to find the similarity solutions for the one-dimensional motion of spherical symmetric shock wave in non-ideal gas influenced by the azimuthal magnetic field and monochromatic radiation in the presence or absence of gravitational field. This paper also aims to study the effects of physical parameters on the strength of shock wave, and on the flow variables in the flow-field region behind the shock front.
Design/methodology/approach
The Roche model is used to describe the gravitational field effects due to a massive nucleus at the point of symmetry. To derive the similarity solutions, the Lie group symmetry method has been used. Also, the numerical solutions to the present problem are obtained by using Rung–Kutta method of the fourth order with the use of Mathematica software. The effects of variation in the parameter of non-idealness of the gas, the gravitation parameter, the strength of the ambient magnetic field and the adiabatic index of the gas on the shock wave, and on the flow variables is discussed. A comparative study between with and without gravitational field is also, made.
Findings
For different choices of the arbitrary constants that appeared in the solution of infinitesimal generators, we have obtained seven distinct cases of similarity solutions. In the absence of the gravitational field, the similarity solution exists to the power and exponential law shock paths, but in the presence of gravitational field, the similarity solution exists to the power law shock path case only. In the absence of gravitational field, the shock strength is enhanced in the exponential law shock path case in comparison to the power law shock path case. It is found that the shock wave decays with an increase in the value of the adiabatic exponent, the strength of magnetic field, non-idealness of the gas or gravitational parameter.
Research limitations/implications
The consideration of medium under the influence of gravitational field due to a heavy nucleus at the center and presence of magnetic field decrease the shock strength. This result may be helpful in designing space vehicle and jet engine.
Practical implications
The result of the present study may be used in the analysis of data from the measurements by space craft in the solar wind and in neighborhood of the Earth’s magnetosphere.
Social implications
The obtained results may be used for mankind.
Originality/value
The study of spherical shock wave propagation influenced by monochromatic radiation and azimuthal magnetic field in a non-ideal gas with or without gravitational field has yet to be discussed by any authors by using the Lie group symmetry method. In this article, we have discussed all possible cases of similarity solutions using the Lie group symmetry method, which is not studied by anyone as known to us.

Abstract
Purpose
This research focuses on the controlling irreversibilities in a radiative, chemically reactive electromagnetohydrodynamics (EMHD) flow of a nanofluid toward a stagnation point. Key considerations include the presence of Ohmic dissipation, linear thermal radiation, second-order chemical reaction with the multiple slips. With these factors, this study aims to provide insights for practical applications where thermal management and energy efficiency are paramount.
Design/methodology/approach
Lie group transformation is used to revert the leading partial differential equations into nonlinear ODE form. Hence, the solutions are attained analytically through differential transformation method-Padé and numerically using the Runge–Kutta–Fehlberg method with shooting procedure, to ensure the precise and reliable determination of the solution. This dual approach highlights the robustness and versatility of the methods.
Findings
The system’s entropy generation is enhanced by incrementing the magnetic field parameter (M), while the electric field (E) and velocity slip parameters (ξ) control its growth. Mass transportation irreversibility and the Bejan number (Be) are significantly increased by the chemical reaction rate (Cr). In addition, there is a boost in the rate of heat transportation by 3.66% while 0.05⩽ξ⩽0.2; meanwhile for 0.2⩽ξ⩽1.1, the rate of mass transportation gets enhanced by 12.87%.
Originality/value
This paper presents a novel approach to analyzing the entropy optimization in a radiative, chemically reactive EMHD nanofluid flow near a stagnation point. Moreover, this research represents a significant advancement in the application of analytical techniques, complemented by numerical approaches to study boundary layer equations.

Abstract
From a world society perspective, common national educational developments are driven by global cultural models that dominated an international liberal order. These models emphasized the centrality of education as an institution, both as a source of human capital and as an inherent human right. Epistemic communities and international organizations circulated these models influencing national educational policies and reforms. However, in recent decades the international liberal order has been challenged with social movements across the political spectrum questioning the value and authority of education in this order. Earlier educational mandates to be more inclusive are attacked with the rights of women, immigrants, and minorities often targeted. Confidence in knowledge grounded in education and science also gets undercut. In a more fragmented world society, educational contestations increase, reflecting surges in nationalist, populist, and traditional illiberal ideas. We reflect on the impact of these challenges on the centrality of education and propose future research directions to ascertain which educational developments are likely to continue to be globally valued and which are more apt to erode.

Abstract
Purpose
This study aims to investigate the association between the co-option of the chief financial officer (CFO) and dividend payments, assessing whether the talent of the CFO affects this association.
Design/methodology/approach
The empirical analyses were based on hand-collected data for 922 firm-year observations from 157 European listed firms, during the period 2013–2019. Empirical models, based on a two-step estimation procedure, involved the use of instrumental variables and the generalised moment method.
Findings
The results show that CFO co-option is negatively associated with the level of dividend payments. It was also found that the degree of CFO talent moderates the negative association between CFO co-option and dividend payments.
Research limitations/implications
This investigation responds to the call for literature which examines how chief executive officer (CEO) – CFO relationships influence firms’ policies and outcomes. The study offers novel evidence for the individual-level characteristics of CFOs which are likely to reduce the effectiveness of CEO power and increase monitoring on corporate decisions on dividends.
Practical implications
The study sheds light on the effect of the interactions between CEOs and CFOs, which are important for investors’ expectations. In this regard, investors may be interested in the CFO profiles which may reduce CEO power over dividend policies.
Originality/value
Unlike previous research, which focused on CEOs, the authors are the first to shed light on the role of CFOs as key decision makers in influencing the dividend policies in modern corporations.

Abstract
This chapter seeks to develop a one-commodity two-sector model, much in line with optimal growth theory tradition owing to Ramsey (1928), Cass (1965), and Koopmans (1965) to overhaul into the dynamic interaction between the formal sector manufacturing activities and environmental quality, assuming an informal sector producing intermediate goods for the formal sector given and thus underline the potential challenges to the conservation of nature in less developed countries. It is thus presented herein, that the in presence of one-sided environmental regulation on the formal sector in exception to the informal sector, economy's long-run equilibrium in terms of consumption, informal sector employment, and capital stock accumulation in the formal sector will dynamically unstable, in what is fundamentally attributable to the switching of environmentally sensitive components of production to informal sector from formal sector, as matter of such partial environmental enforcement.

Abstract
Purpose
Clawback provisions entitle shareholders to recover previously awarded incentive compensation after the discovery of accounting manipulation or misconduct. The author evaluates the impact of clawback enforcement heterogeneity on the horizon of executive compensation.
Design/methodology/approach
The author provides empirical tests to evaluate the impact of clawback adoption decisions. The author deals with the endogeneity of clawback adoption decisions through an instrumental variables strategy that exploits the transmission of governance choices within firms’ networks.
Findings
While the author finds that clawback adoption reduces the frequency of accounting manipulation, this reduction is accompanied by heterogeneous effects on the horizon of executive pay across firms. Clawback adopters with high director independence, high leverage, high managerial termination payments and low executive ownership tilt their compensation toward the short-term.
Practical implications
The results, robust to alternative specifications, suggest that clawbacks allow strong-enforcement firms to tilt compensation toward the short-term, offsetting some of the direct manipulation disincentives generated by the clawback. The stock market reacts positively to the adoption in firms with weak enforcement, suggesting that clawbacks significantly reduce the managers’ rent-extraction capacity.
Originality/value
Using a novel empirical and identification approach, the results suggest that clawbacks allow strong-enforcement firms to tilt compensation toward the short-term, offsetting some of the direct manipulation disincentives generated by the clawback.
