Abstract
Purpose
The purpose of this paper is to develop a group acceptance sampling plan (GASP) for a resubmitted lot when the lifetime of a product follows odds exponential log logistic distribution introduced by Rao and Rao (2014). The parameters of the proposed plan such as minimum group size and acceptance number are determined for a pre-specified consumer’s risk, number of testers and the test termination time. The authors compare the proposed plan with the ordinary GASP, and the results are illustrated with live data example.
Design/methodology/approach
The parameters of the proposed plan such as minimum group size and acceptance number are determined for a pre-specified consumer’s risk, number of testers and the test termination time.
Findings
The authors determined the group size and acceptance number.
Research limitations/implications
No specific limitations.
Practical implications
This methodology can be applicable in industry to study quality control.
Social implications
This methodology can be applicable in health study.
Originality/value
The parameters of the proposed plan such as minimum group size and acceptance number are determined for a pre-specified consumer’s risk, number of testers and the test termination time.

Abstract
Purpose
The purpose of study to this article is to analyze the Rayleigh wave propagation in an isotropic dry sandy thermoelastic half-space. Various wave characteristics, i.e wave velocity, penetration depth and temperature have been derived and represented graphically. The generalized secular equation and classical dispersion equation of Rayleigh wave is obtained in a compact form.
Design/methodology/approach
The present article deals with the propagation of Rayleigh surface wave in a homogeneous, dry sandy thermoelastic half-space. The dispersion equation for the proposed model is derived in closed form and computed analytically. The velocity of Rayleigh surface wave is discussed through graphs. Phase velocity and penetration depth of generated quasi P, quasi SH wave, and thermal mode wave is computed mathematically and analyzed graphically. To illustrate the analytical developments, some particular cases are deliberated, which agrees with the classical equation of Rayleigh waves.
Findings
The dispersion equation of Rayleigh waves in the presence of thermal conductivity for a dry sandy thermoelastic medium has been derived. The dry sandiness parameter plays an effective role in thermoelastic media, especially with respect to the reference temperature for η = 0.6,0.8,1. The significant difference in η changes a lot in thermal parameters that are obvious from graphs. The penetration depth and phase velocity for generated quasi-wave is deduced due to the propagation of Rayleigh wave. The generalized secular equation and classical dispersion equation of Rayleigh wave is obtained in a compact form.
Originality/value
Rayleigh surface wave propagation in dry sandy thermoelastic medium has not been attempted so far. In the present investigation, the propagation of Rayleigh waves in dry sandy thermoelastic half-space has been considered. This study will find its applications in the design of surface acoustic wave devices, earthquake engineering structural mechanics and damages in the characterization of materials.

Abstract
Purpose
Lifetime data are used in many different applied sciences, like biomedicine, engineering, insurance and finance and others. The purpose of this paper is to develop a new acceptance sampling plans for Rama distribution when the mean lifetime test is truncated at a pre-determined time. The minimum sample sizes required to assert the specified life mean is obtained for a given customer’s risk. The operating characteristic function values of the sampling plans and producer’s risk are calculated.
Design/methodology/approach
The results are illustrated using numerical examples and a real data set is considered to illustrate the performance of the suggested acceptance sampling plans and how it can be used for the industry applications.
Findings
This paper shows a new acceptance sampling plans based on Rama distribution in the particular case when the mean life time test is truncated.
Originality/value
The results calculated in this paper demonstrate the differences between OC values for different distributions taken into account. In particular, OC values of Rama distribution are found to be less than the proposed distribution counterparts.

Abstract
Purpose
Literature, spanning industrial organization and strategic management disciplines, uses variance decomposition to understand the relative importance of firm, industry and business group effects in shaping profitability variations. Some literature analyzes firm profitability under transition to liberalization. Previous research has taken a static before-and-after view on institutional change. This paper aims to focus on the dynamic process of liberalization in India, analyzing how different institutional regime changes alter firm behavior leading to changes in profitability patterns.
Design/methodology/approach
Based on a panel data set of several thousand Indian firms, spanning the 26-year period between 1980-1981 and 2005-2006, the authors determine the relative importance of firm, industry and business group effects in explaining manufacturing firms’ profitability variances across different institutional phases. The authors evaluate three propositions that help assess transition dynamics between phases. They determine the quantum of catch-up or falling behind by firms.
Findings
Different industries emerge as profitability leaders, as the economy progresses through different liberalization phases. Business groups that have been more effective in resource appropriation, rent-seeking, politician management and non-market activities in a controlled regime are replaced as profit leaders by those that, in a free-market economy, can be capable of intra-business resource allocation tasks and leveraging corporate capabilities.
Originality/value
The approach demonstrates how to analyze the underlying detailed structure of firm-level data, and performance outcomes, to derive nuanced interpretation of factors giving rise to the effects that explain profitability variances, and how to assess the way these effects behave over time. The dynamic evidence-based approach highlights what factors matter, where, when and why, in influencing profitability variances, which are a key dimension of industrial and economic performance.

Abstract
Purpose
The purpose of this research is to analyse the development and implementation of waste-to-energy (WtE) power plants as a strategy to manage municipal solid waste (MSW) in Indonesia. It aims to identify key determinants for the successful adoption of WtE technology in developing countries, focusing on the Benowo WtE power plant, Indonesia’s first large-scale WtE project.
Design/methodology/approach
This study reviews the development of the Benowo WtE power plant, examining political, regulatory and financial factors influencing its implementation. It analyses the roles of national and local government institutions, highlighting critical elements for the successful deployment of WtE projects in a developing country context.
Findings
The review shows that the success of WtE projects in Indonesia is significantly influenced by strong local government commitment, supported by political, financial and regulatory backing from the national government. The Benowo WtE power plant’s development demonstrates that with adequate support, WtE can be a viable solution for managing MSW and generating energy in developing countries. The study also identifies barriers to broader WtE adoption in similar contexts.
Research limitations/implications
The study is limited to 12 WtE projects in Indonesia, with in-depth analysis focused on a single case, potentially overlooking challenges and opportunities in other regions. Furthermore, the study does not include an economic analysis, such as a feasibility assessment. Future research could expand to multiple WtE projects and incorporate primary data collection to provide more comprehensive findings, including feasibility studies of each project.
Practical implications
The findings provide practical guidance for policymakers and stakeholders in developing countries, identifying critical areas for successful WtE deployment and offering a blueprint based on the Benowo WtE power plant.
Social implications
Implementing WtE projects can improve waste management, reduce pollution, enhance public health, create jobs and stimulate local economies. The study underscores the importance of government and community collaboration in addressing environmental challenges and fostering shared responsibility.
Originality/value
This research offers novel insights into WtE technology development in a developing country, specifically focusing on Indonesia’s first large-scale WtE power plant. By analysing the Benowo WtE power plant, the study provides valuable lessons and strategies for other developing nations aiming to adopt WtE solutions for MSW management, emphasising the critical role of government support.

Abstract
Purpose
The purpose of this paper is to present an overview of different aspects of inulin functionality in meat and poultry products.
Design/methodology/approach
Several studies on the physiochemical, textural and sensorial effects of inulin incorporated in meat and poultry products as fat replacer and texture modifier were reviewed.
Findings
Inulin is a plant-derived carbohydrate composed of fructose units and glucosyl moieties at the end of the chain that exhibits unique nutritional and technological benefits. Among its main healthy characteristics, it has been reported to reduce the risk of colon cancer, arteriosclerosis, osteoporosis, diabetes and obesity, to maintain low levels of triglycerides and cholesterol in serum and stimulate the immune system. As a functional food ingredient, it can be used in various foods as a fat replacer, improves water-holding capacity and emulsion stability, as well as modifying the texture and viscosity of foods. Incorporation of inulin into meat and poultry products can be beneficial in producing low-fat products with desirable texture and sensory attributes.
Originality/value
There are limited reviews regarding the application of inulin in meat and poultry products. In this review, chemical composition and physicochemical properties of inulin, its health effects and various effects of inulin incorporation into meat and poultry products including, physicochemical, textural and sensory characteristics of these products are discussed.

Abstract
Purpose
This study examines consumers’ usage intention towards retail metaverse banking. This research also investigated the mediating impact of trust and distrust. This research also examined the moderating impact of perceived security concerns.
Design/methodology/approach
Firstly, a qualitative study is performed to explore the benefits and sacrifices that may influence usage intention. Further, the quantitative study gathered a total of 308 responses to investigate the proposed hypotheses.
Findings
The findings suggest that perceived anthropomorphism and perceived immersion positively impact the usage intention towards retail metaverse banking. Further, lack of social interaction and perceived vulnerability had a negative influence towards retail metaverse banking. Further, trust and distrust were found to be significant mediators. Also, perceived security concern was shown to be a significant moderator.
Originality/value
The study contributes to the metaverse literature and suggests to banks how to enhance usage intention towards retail metaverse banking. The study also enriches the literature on dual-factor theory.

Abstract
Purpose
Many REpresentational State Transfer (RESTful) Web services suffered from anti-patterns problem, which may diminish the sustainability of the services. The anti-patterns problem could happen in the code of the programme or the uniform resource identifiers (URIs) of RESTful Web services. This study aims to address the problem by proposing a technique and an algorithm for detecting anti-patterns in RESTful Web services. Specifically, the technique is designed based on URIs parsing process.
Design/methodology/approach
The study was conducted following the design science research process, which has six activities, namely, identifying problems, identifying solutions, design the solutions, demonstrate the solution, evaluation and communicate the solution. The proposed technique was embedded in an algorithm and evaluated in four phases covering the process of extracting the URIs, implementing the anti-pattern detection algorithm, detecting the anti-patterns and validating the results.
Findings
The results of the study suggested an acceptable level of accuracy for the anti-patterns detection with 82.30% of precision, 87.86% of recall and 84.93% of F-measure.
Practical implications
The technique and the algorithm can be used by developers of RESTful Web services to detect possible anti-pattern occurrences in the service-based systems.
Originality/value
The technique is personalised to detect amorphous URI and ambiguous name anti-patterns in which it scans the Web service URIs using specified rules and compares them with pre-determined syntax and corpus.

Abstract
Purpose
The use of technology in today’s life has skyrocketed, leaving information providers with no option but to implement technological initiatives that will enable effective information access and dissemination. This paper aims to assess the readiness of Botswana public librarians to adopt the use of technology in the management of libraries and dissemination of information.
Design/methodology/approach
Convenience and purposive sampling were used to collect data from 21 participants via Survey Monkey software. The study questions were based on the Technology Readiness Index (TRI) by Parasuraman and Colby (2015). In addition, mixed-methods approach was adopted to collect both qualitative and quantitative data.
Findings
The study found out that public librarians are ready to adopt information and communications technologies (ICTs) in library services. This is evidenced by their usage of social media networks and emails. Results also show that public libraries in Botswana are facing various challenges such as low bandwidth, shortage of computers, lack of timely technological support and ICT skills by librarians.
Research limitations/implications
These findings call upon the Ministry of Youth Empowerment, Sport and Culture Development to setup/construct more public libraries and equip them with the necessary technology. This will enhance productivity and help libraries to meet the needs of the twenty-first century information seekers. An in-depth study should be conducted to establish the technological status in Botswana public libraries.
Originality/value
This is the first study conducted in Botswana to assess the public librarians’ readiness to adopt new technologies.
