Abstract
Purpose
This paper aims to investigate the dimensional accuracy and surface roughness of printed masked stereolithography (m-SLA) parts. The fabricated specimens of photosensitive polymer resin have complex shapes and various features. The influence of four process parameters of m-SLA, including layer height, exposure time, light-off delay and print orientation, is studied on response characteristics.
Design/methodology/approach
The Box–Behnken design of response surface methodology is used to examine the effect of process parameters on the shrinkage of various geometrical dimensions like diameter, length, width, and height of different features in a complex shape. Additionally, a multi-response optimization has been carried out using the desirability function to minimize the surface roughness and printing time and maximize the dimensional accuracy.
Findings
The layer height and print orientation influence the surface roughness of parts. An increase in layer height results in increased surface roughness, and the orientation parallel to the z-axis of the machine gives the highest surface roughness. The dimensional accuracy of m-SLA parts is influenced by layer height, exposure time, and print orientation. Although not significant in dimensional accuracy and surface roughness, the light-off delay can affect printing time apart from other parameters like layer height and print orientation.
Originality/value
The effect of layer height and print orientation on dimensional accuracy, printing time, and surface roughness is investigated by researchers using simple shapes in other vat photopolymerization techniques. The present work is focused on studying the effect of these parameters and additional parameters like light-off delay in complicated geometrical parts in m-SLA.

Abstract
Purpose: Tax fraudulence is not an aberration, but it is a deliberate attempt to get rid of the tax burden. The government took enormous measures to curtail tax fraud, which seems dispensable. Taxation is the largest area that needs to be explored as individuals make discrete stings while filing taxes. Since compliance-focussed systems for tax collection are missing, this department is facing difficulties in providing quality data. This chapter will cover blockchain operations in the tax system to streamline the entire process and highlight the challenges.
Need of the Study: As the growth of technology is in the boom stage, research should be carried out to create more awareness regarding its usage and its possible threats. This study will spark more light on taxation by taking blockchain as the torch to improvise the vision.
Design/methodology/approach: The researcher did a comprehensive analysis of the Indian Tax Department and determined whether simplifying taxation could be possible through blockchain. The study gathered concrete facts about the various challenges faced while implementing this system.
Finding: Blockchain technology is rapidly making a roadmap in the taxation system, and there is tremendous potential to create a future vision with blockchain.
Practical Implications: This study will accentuate the function of blockchain technology that is becoming more prominent in the global technology sphere. This study will aid scholars in elaborating on the role of blockchain technology.

Abstract
Purpose: Technological innovations and frameworks that provide a framework for unification have evolved to improve information exchange across organisational units and information security. These integration technologies share and communicate information using defined protocols and different data. Service-oriented architecture (SOA) is a significant emerging approach that enables modular design solution construction.
Methodology: These designs are beneficial when many apps operating on different architectures and networks need to connect. A well-defined strategy and company-specific guidelines are essential for ensuring the firm’s systematic adoption of such an architecture. The critical components of MASSOASCM ‘(Multi-Agent System Service Oriented Architecture Supply Chain Management’ are a multi-agent system (MAS), a service-oriented structure, and supplier management. The MASSOASCM model has been made, and a production unit has been made to show how it works.
Findings: It has been stated that it saves development costs, and inventory management, all of which are critical concerns in any company. Our goal is to create an inventory control approach that relies on MAS and SOA but also a simulation that demonstrates how it works and may enhance Supply Chain Management (SCM) productivity in a production plant.
Practical Implications: The SCM implementation comprises three different services: SCM, SOA, and MAS. These facilities are constructed, maintained, planned, and implemented individually before being brought together collectively using MAS and SOA techniques.

Abstract
Purpose
Free convection inside a square, circular, or elliptic cavity with gravity oscillation is a special class of problems. In a microgravity environment, the reduction or elimination of natural convection can enhance the properties and performances of materials such as crystals. However, aboard orbiting spacecrafts, all objects undergo low‐amplitude broadband perturbed accelerations, or g‐jitter, caused by crew's activities, orbiter maneuvers, equipment vibrations, solar drag, and other sources. Therefore, there is a growing interest in understanding the effects of these perturbations on the systems' behavior. There is no information of flow, heat transfer, and irreversibility analyses in the current literature that considers such a situation in a porous medium. This motivates this paper to conduct the current research.
Design/methodology/approach
As a special case, an elliptic enclosure is considered here. The enclosure is filled with a porous medium whose flow is modeled by the Darcy momentum equation. The full governing differential equations are simplified by the Boussinesq approximation and solved by a finite volume method. Prandtl number (Pr) is fixed at 1.
Findings
The average Nusselt number (Nu), Bejan number (Be), and entropy generation number (Ns) are adopted to characterize the heat transfer and irreversibilities. Gravity oscillation introduces periodic behavior to the Nu, Be, and Ns rate. Depending on the frequency and the Rayleigh number (Ra), three distinguishable regimes of ψ behavior are identified: periodic and synchronous, periodic and asynchronous, and non‐periodic and asynchronous.
Research limitations/implications
Current research is valid only for laminar Darcy type flow situation in the porous media.
Originality/value
This paper will extend the existing theory of thermovibrational convection to porous media.

Abstract
Purpose
The purpose of this paper is to investigate the key attributes that drive Muslim consumer purchase behavior in the context of imported Western food in Pakistan.
Design/methodology/approach
In-depth, semi-structured interviews were used as a data collection tool. In this research, the in-depth interview data were analysed by using the manual content analysis (MCA) technique. Moreover, Leximancer software was used to reanalyse the data to enhance the trustworthiness of the MCA results. A total sample of 43 Muslim consumers from three metropolitan cities in Pakistan participated in the research. The sample comprises professionals, housewives and both college and university students.
Findings
Muslim consumers in Pakistan look at both the intrinsic and extrinsic attributes when purchasing imported Western food. The ruling factors explored were product taste, ingredients, freshness, hygiene, brand name and overall product quality. However, product packaging and labeling also play a significant role. Participants were of the view that imported Western food provides a better, unique consumption experience and an opportunity to choose from a wide variety of food options. Interestingly, interview findings reveal that Western food product attributes surpass the Islamic concept of moderate spending, thus convincing Muslim consumers to engage in the consumption of imported Western food.
Social implications
The presence of imported Western food may improve quality of life by having more opportunities and healthier options for the nation. If the Western food products are stamped Halal or made with Halal ingredients the product has a fair chance of adoption and penetration in the society. Further, it may result in overall health improvements within the society, which is already a major concern in the Pakistani consumer market. Also, food products coming from the Western world induces mindfulness; people are more aware about innovative and useful ingredients that can satisfy their taste buds.
Originality/value
This paper found that Pakistani Muslim consumers are not really concerned about the Islamic concept of moderate spending, and thus, established that Pakistani Muslim consumers are more concerned about product value rather than their Islamic teaching of moderate spending. From a population, with 97 per cent Muslim majority, product packaging and labeling were found to be a dominant and deciding factor, which, in itself, is an interesting finding. Further, established Western brand names help Muslim consumers to recognize products and plays a vital role in their purchase decisions. However, within product labeling, the element of halal ingredients was found to be a deciding factor, but not a leading factor, in purchase decisions.

Abstract
Purpose
The purpose of this research is to compare the board quality's (BQ) impacts on the financial performance (FP) of conventional and Islamic banks (IBs) after the Subprime financial crisis. The main reason is to help financial stakeholders choose the best performing and most appropriate bank type with its engagement based on the BQ index.
Design/methodology/approach
Based on the existing gap in previous researches and by using the GLS method (Generalized Least Squares method), the author compared the BQ's impacts on the FP of conventional and IBs. Settings of the FP and BQ were collected from 30 countries located on 4 continents. Two equal samples were tested; each of them is composed of 112 banks. The author concentrated only on the banks that have published regularly the banks' annual reports over the period 2010–2018.
Findings
Cylindrical panel results revealed that in conventional banks (CBs), the BQ has negatively affected banks' FP, while in IBs the BQ's impacts on the banks’' FP is ambiguous. Nevertheless, the positive impacts are more significant on the IBs' FP than the negative impacts on the IBs' FP.
Practical implications
The main practical contribution is the identification and distinction between the impacts of board determinants' quality on the shareholders' profits in the case of conventional and IBs. Hence, conventional or IBs which have a bad BQ will generate less FP and will be classified as a lender of bankruptcy danger for the bank customer. Besides, whatever the bank type, in a financial stable period, good BQ positively influences FP and provides a good impression to stakeholders. Otherwise, FP indicates that the banks suffer from the weaknesses of the board quality determinants.
Originality/value
Returning to the finance and banking governance literature, the author's article provides the first conditional and demonstrative analysis that detailed a logical comparative process to analyze the correlation between the board determinants' quality and the financial performance of conventional and IBs. However, previous research has always discussed the main role of the board as an internal governance mechanism on the FP separately in each bank type.
