Abstract
This essay seeks to extend the original gambit of this forum, of thinking possible modes of postcolonial sociology, unto a more relational terrain. It takes as its point of departure the vexed status of history in sociology and the hermeneutic suspicion of comparison in postcolonial theory. Any potential rapprochement between postcolonial theory and sociology must engage with the deeply incongruent status of history and comparison across these fields. I attempt to bridge this divide historically by revisiting an anti-imperial internationalist sociology forged in interwar colonial India. I seek thereby to show what Pierre Bourdieu called a “particular case of the possible” and to participate in ongoing efforts to “provincialize” sociology.

Abstract
Purpose
This paper aims to consider a sustainable inventory model with price dependent demand, non-instantaneous deterioration rate, discount facility, partially backlogged shortages and advance and delay in payments for a two-warehouse system.
Design/methodology/approach
This model considered a non-instantaneous deterioration, which starts after a certain period with a constant rate. The deterioration rate in the rented warehouse is more compared to own warehouse. The proposed model focused on two things. The first one is to the benefits of the advance payments strategy and delayed payment for the retailer and supplier, where the two-warehouse system is available and the second one is using an appropriate discount facility on no of the installment to maximize the total profit. The classical optimization technique is used to solve the problem.
Findings
The combination of trade-credits and advance payments is initiated to provide more benefits to the retailer. The findings prove that advance payments, which are received from the retailer to the supplier are beneficial for the supplier, who can influence the demand increase because of higher lower selling prices. Decreasing the selling price is used as a catalyst to increase demand. It also extends the discount concept of Khan et al. (2019, 2019b).
Research limitations/implications
This model is limited by the fact that it does not consider variable deterioration. Therefore, the proposed inventory model could be extended by considering variable deterioration, as well as fully backlogged shortages and time-dependent demand function.
Originality/value
The study simultaneously considers a non-instantaneous deterioration inventory model, advance-payment, trade-credit for a sustainable two-warehouse inventory system. From the literature search to the best of knowledge no researcher has undergone this sort of study.

Abstract
Purpose
In the present investigation, hydromagnetic boundary layer flow of Walters’-B fluid over a vertical porous surface implanted in a porous material under the action of a strong external applied magnetic field and rotation is presented. In several industrial applications, the external applied magnetic field is strong enough to produce Hall and ion-slip currents. Thus, the influence of Hall and ion-slip currents is also considered in this analysis. The flow through configuration is generated because of time varying motion of the free-stream and buoyancy action.
Design/methodology/approach
Regular perturbation scheme is used to obtain the solution of the system of coupled partial differential equations representing the mathematical model of the problem. Numerical computation has been performed to notice the change in flow behavior and the numerical results for velocity field, temperature field, species concentration, skin friction, rate of heat and mass transfer are presented through graphs and tables.
Findings
An important fact noticed that the exponential time varying motion of the free-stream induces reverse flow in the direction perpendicular to the main flow. Rising values of the strength of the applied magnetic field give increment in the fluid velocity in the neighbourhood of the vertical surface, this may cause because of the exponential motion of the free-stream. The behaviour of the Darcian drag force is similar as magnetic field on fluid flow.
Originality/value
In literature, very less research works are available on Walters’-B fluid where unsteadiness in the system occurs because of time varying motion of the free-stream. In this paper, the authors have made an attempt to study the action of Hall and ion-slip currents, rotation and external applied magnetic field on hydromagnetic boundary layer flow of Walters’-B fluid over a vertical surface implanted in a porous material.

Abstract
Purpose
This research work introduces an imperfect production system where the demand is assumed to be stochastic and it is influenced by random selling price. The shift time from an “in-control” state to an “out-of-control” state is exponentially distributed. The accumulated inventory contains both perfect and defective items which are all sold with a free repair warranty (FRW) offer. Complete back ordering of shortages are taken into account. The purpose of this paper is to determine the optimal selling price and hence the optimal production lot size such that the expected profit is maximized.
Design/methodology/approach
The general model is discussed separately for both types of uniformly distributed selling price-sensitive demand pattern: additive type and multiplicative type. Numerical examples and graphical representations of the optimal solutions are provided to illustrate the models.
Findings
This paper helps the manager to manage future situations and it may be considered as a base work for the researchers to work in this direction.
Research limitations/implications
The main limitation of this model is to consider a single item for a single channel system. There are many correlated issues that need to be further investigated. The future study in this direction may include the consideration of multi-items, diverse demand pattern with different types of price distributions.
Originality/value
In the production inventory literature, plenty of articles are available considering imperfect production but none of them have considered selling price-sensitive stochastic demand where the sales price is random in character under an FRW offer.

Abstract
This paper proposes a framework for evaluating the impact of e‐commerce on the roles of distributors in the semiconductor industry for four different types of products, namely differentiated products, architectural products, technological products, and complex products. Questionnaire and the purposive sampling method were used to collect data from respondents in the distribution industry. The results of the study show that the salience of the roles is increasing. In addition, there is strong likelihood of e‐commerce replacing the traditional distributors, more so for less standardized products such as complex, technological, and architectural products.

Abstract
Purpose
This paper aims to explore optimal pricing policies and characteristics of a two-level dual-channel supply chain under price- and delivery time-sensitive demand. Besides price of the product, the delivery lead time is also a crucial factor in customers’ purchase decisions. A longer delivery lead time would diminish customers’ acceptance and faithfulness on the online channel, while a shorter delivery lead time would lead to incorporation of a substantial amount of logistics costs. In formulation of mathematical model, the effects of delivery lead time on the manufacturer and the retailer’s pricing strategies and profits in cooperative and non-cooperative dual-channel supply chain are explained analytically.
Design/methodology/approach
The analytical models are formed for both non-cooperative and cooperative scenarios under inconsistent and consistent pricing. The authors examine whether revenue sharing (RS) contract or delivery cost sharing contract can solely coordinate the dual-channel supply chain. If a single contract fails, then the combination of RS contract with delivery cost sharing to achieve channel coordination is discussed.
Findings
It is found that the RS or delivery cost sharing contract cannot coordinate the channel individually but revenue and delivery cost sharing contract jointly coordinate the channel. All analytical results are illustrated numerically, along with sensitivity analysis.
Research limitations/implications
There are many correlated issues that need to be further investigated. First, one good extension to this research may include the consideration of the channel structure with competitive retailers. It will be interesting to analyze the performance of coordination mechanisms by considering the retailer as a Stackelberg leader in retailing.
Originality/value
The findings and subsequent methodological discussions aim to provide practical guidance to retailers who are allowing customers to choose how, when and where they interact and purchase by offering a combination of websites (fully functional and mobile-enabled), catalogs and stores with increasing convergence of channels.

Abstract
Resilient and sustainable supply chain management is emerging as a focused area of research in the field of supply chain management. This article aims to introduce this edition of Advances in Environmental Accounting and Management and explore opportunities for research related to resilient and sustainable supply chain management. A critical analysis of literature found the need for developing the theory underpinning resilient and sustainable supply chains and the need for rich empirical studies. The six articles included in this edition present a variety of contexts including food supply chain, environmental accounting models, energy sector, human resources, modern slavery, horticultural worker exploitation and sustainable transport in jurisdictions like Australia, European Union, Fiji and India. Overall, this edition contributes to both theoretical and empirical literature on resilient and sustainable supply chain management and presents a repository of research that explores this area using an accounting and environmental management perspective.

Abstract
Purpose
The utilisation of food waste/by‐products helps to increase produce recovery and enhances nutrition in low‐cost food without any appreciable increase in product cost. The storage behaviour of the product must be studied before commercialisation of the product. This paper aims to focus on this process.
Design/methodology/approach
Extrudates (25 g) prepared under optimised conditions of proportion (rice flour, pulse powder and carrot pomace), moisture content, screw speed and die temperature, were sealed using a polythene sealing machine in LDPE bags and aluminium laminated LDPE bags. The bags were then stored for six months in an incubator at temperature of 38±2°C to evaluate the stability of the product. The extrudates were analysed for change in colour, hardness, moisture content and sensory characteristics.
Findings
Zero‐ and first‐order models were fitted for prediction purposes. The minimum overall change in color ΔE value, minimum increase in moisture content and minimum increase in hardness was observed in aluminium laminated LDPE bags. The zero order model better predicted the variation of L*, b*, ΔE, moisture content and hardness during storage, whereas first order model was better fitted for the a* value.
Originality/value
The carrot pomace has the potential to be used as a food ingredient that enhances the nutritional attributes of products along with a reduction in cost. Extruded products were successfully developed in the laboratory using carrot pomace as one of the ingredients. This study evaluates the kinetic changes during the storage of carrot pomace based extruded snacks.

Abstract
Green supply chain (GSC) modelling is still evolving, yet according to the literature, there is no standard and comprehensive approach for modelling GSCs. This chapter attempts to examine this remarkable gap in research by proposing a standard approach for industrial supply chain (SC) modelling, which allows integrating all relevant environmental constraints. This new approach is inspired from other methodologies proposed earlier regardless of their area of study and implemented via a case study in fish canning industry. The steps of the proposed approach are based on Artificial Intelligence (AI), which has become a mainstream trend nowadays. The proposed approach may help managers and researchers and could provide a guideline for GSC modelling.
