Abstract
Purpose
The proposed IT2FMOVMI model intends to concurrently minimize total cost and warehouse space for the single vendor-retailer, multi-item and a consolidated vendor store. Regarding demand and order quantities with the deterministic and type-1 fuzzy numbers, we have also formulated the classic/crisp MOVMI model and type-1 fuzzy MOVMI (T1FMOVMI) model. The suggested solution technique can solve both crisp MOVMI and T1FMOVMI problems. By finding the optimal ordered quantities and backorder levels, the Pareto-fronts are constructed to form the solution sets for the three models.
Design/methodology/approach
A multi-objective vendor managed inventory (MOVMI) is the most recognized marketing and delivery technique for the service provider and the retail in the supply chain in Industry 4.0. Due to the evolving market conditions, the characteristics of the individual product, the delivery period and the manufacturing costs, the demand rate and order quantity of the MOVMI device are highly unpredictable. In such a scenario, a MOVMI system with a deterministic demand rate and order quantity cannot be designed to estimate the highly unforeseen cost of the problem. This paper introduces a novel interval type-2 fuzzy multi-objective vendor managed inventory (IT2FMOVMI) system, which uses interval type-2 fuzzy numbers (IT2FNs) to represent demand rate and order quantities. As the model is an NP-hard, the well-known meta-heuristic algorithm named NSGA-II (Non-dominated sorted genetic algorithm-II) with EKM (Enhanced Karnink-Mendel) algorithm based solution method has been established.
Findings
The experimental simulations for the five test problems that demonstrated distinct conditions are considered from the real-datasets of SAPCO company. Experimental study concludes that T1FMOVMI and crisp MOVMI schemes are outclassed by IT2FMOVMI model, offering more accurate Pareto-Fronts and efficiency measurement values.
Originality/value
Using fuzzy sets theory, a significant amount of work has been already done in past decades from various points of views to model the MOVMI. However, this is the very first attempt to introduce type-2 fuzzy modelling for the problem to address the realistic implementation of the imprecise parameters.

Abstract
Purpose
Optimum utilization of investments has always been considered one of the most crucial aspects of capital markets. Investment into various securities is the subject of portfolio optimization intent to maximize return at minimum risk. In this series, a population-based evolutionary approach, stochastic fractal search (SFS), is derived from the natural growth phenomenon. This study aims to develop portfolio selection model using SFS approach to construct an efficient portfolio by optimizing the Sharpe ratio with risk budgeting constraints.
Design/methodology/approach
This paper proposes a constrained portfolio optimization model using the SFS approach with risk-budgeting constraints. SFS is an evolutionary method inspired by the natural growth process which has been modeled using the fractal theory. Experimental analysis has been conducted to determine the effectiveness of the proposed model by making comparisons with state-of-the-art from domain such as genetic algorithm, particle swarm optimization, simulated annealing and differential evolution. The real datasets of the Indian stock exchanges and datasets of global stock exchanges such as Nikkei 225, DAX 100, FTSE 100, Hang Seng31 and S&P 100 have been taken in the study.
Findings
The study confirms the better performance of the SFS model among its peers. Also, statistical analysis has been done using SPSS 20 to confirm the hypothesis developed in the experimental analysis.
Originality/value
In the recent past, researchers have already proposed a significant number of models to solve portfolio selection problems using the meta-heuristic approach. However, this is the first attempt to apply the SFS optimization approach to the problem.

Abstract
Purpose
This study examines the dynamics of the modesty-conscious market within the global fashion industry. Specifically, the research aims to understand and analyse the preferences of consumers in this market segment and provide guidance for fashion companies seeking to engage with this sizable audience consumer demand for modest fashion, such as loose-fitting garments and headscarves for women.
Design/methodology/approach
Employing a mono-method quantitative research approach, this study uses a comprehensive big data analytics framework to analyseashion data sets obtained from e-commerce websites.
Findings
The findings highlight a persistent and growing demand for modest fashion; that demand proved resilient in the face of challenges presented by the COVID-19 pandemic. Modest shoppers demonstrate price sensitivity, and their preference for premium brands over affordable ones varies considerably. Crucial factors contributing to the success of modest clothing as best-sellers include price, retailer, colour and fabric, while the discount feature is less important.
Research limitations/implications
While this research provides significant insights, it is important to acknowledge its limitations. This study relies on data gathered from certain e-commerce websites, and specific nuances of consumer behaviour may not be fully captured. In addition, the scope is limited to a specific timeframe and may not account for long-term market shifts.
Practical implications
Fashion companies could use the results of this study to customise their strategy for engaging the modesty-conscious demographic. Comprehending the significance of elements such as price, retailer, colour and fabric can allow firms to enhance their product offerings and marketing strategies.
Social implications
This study highlights the social ramifications of the modesty-focused industry, stressing the changing tastes and requirements of customers within this sector. By aligning their strategies with these societal shifts, fashion companies can contribute to a more inclusive and diverse industry landscape.
Originality/value
This research contributes to the academic literature on modest fashion by using a unique combination of exploratory data analysis and machine learning techniques with fashion e-commerce data sets. This study addresses a gap in the use of big data within this field, and provides novel insights into consumer demand for modest garments. This study challenges the prevailing assumption that consumers of modest fashion prioritise premium pricing, and offers fresh insights into their price sensitivity across both mass-market and luxury segments. It contributes to the literature on consumer behaviour in niche fashion markets and introduces a theoretical framework for understanding the intersection of fashion, culture and consumer economics within the context of modest fashion.

Abstract
Purpose
This study seeks to deepen the understanding of the political process underlying the establishment and evolution of corporate governance (CG) regulations in a developing country.
Design/methodology/approach
Drawing on regulatory space concept (Hancher and Moran, 1989) and Oliver's (1991) typology of strategic responses, the authors identify which actor participated in and benefitted from the establishment of a new transnational CG regulation in Pakistan. Data were collected through interviews and from the published secondary sources.
Findings
The findings highlighted regulations are being influenced and shaped up by the political process of negotiation, bargaining, manipulation and domination between powerful and resourceful actors in a given regulatory space. National regulators and regulatees can be indeed fervent opponents to the transnational regulations when it comes to protecting their well-rooted national interests.
Originality/value
This study contributes to the accounting literature by illustrating political processes through which internationally recognised CG practices are resisted, negotiated and implemented in the developing countries. The regulator must pay attention that the outcome of the regulatory change process is the result of carefully crafted and conscious strategies of actors in the regulatory space.

Abstract
Purpose
The purpose of this paper is to review the nutritional composition, phytochemicals and bioactive compounds of black rice such as flavonoids, phenolic compounds and their health benefits. Black rice has also been used in medicine and for curing diabetes, obesity, cardiovascular diseases and cancer. Green technologies such as microwave-assisted extraction, supercritical fluid extraction and pulse electric field assisted extraction are very useful for the extraction of bioactive compounds as these reduce the use of energy and are environmental friendly. Black rice in different forms can be incorporated in various food products such as bakery, dairy and meat products.
Design/methodology/approach
Information and data were collected from different sources such as Google Scholar, Research Gate, online journals available at Banaras Hindu University library, Web of Science and Scopus. A database of more than 80 scientific sources from different sources was made as per the headings and subheadings of the paper.
Findings
Black rice is a type of rice species (Oryza sativa L.) and very good source of various nutrients and one of the nutritious varieties of rice. It is a good reservoir of essential amino acids such as lysine, tryptophan, minerals including iron, calcium, phosphorus, zinc and selenium; vitamins such as vitamin B1, vitamin B2 and folic acid. Various recent methods of extraction of bioactive compounds from black rice are suggested.
Originality/value
Researchers and scientists have considered black rice as a “Super Food” because of its nutritional profile. Black rice has antioxidant activity, anti-inflammatory activity, anticancer activity, antihyperlipidemia and antihyperglycemia and anti-allergic activity. There is a need to create awareness among the consumers about its nutritional profile and therapeutic properties.

Abstract
Purpose
Using trait activation theory (TAT), this paper aims to empirically assess that work drive (WD) personality characteristics of employees will express better towards intrapreneurial behaviour (IB) outcomes in higher levels of job autonomy (JA) at the workplace.
Design/methodology/approach
Using cross-sectional design, a total of 258 engineering employees from the automotive industry of Pakistan were surveyed. The partial least square structural equation modelling (PLS-SEM) statistical method was used to evaluate the hypothesised theoretical model.
Findings
Statistical results revealed a significant and positive relationship between WD and IB. WD personality was also found to be activated with its interplay with JA for personality expression towards IB.
Practical implications
The present study offers a deeper insight into the interplay of organisational and individual factors as determinants of IB of employees. The study's findings suggested the importance of the rightful application of organisational situational cues in person–situation interaction for positive workplace behaviours by employees. Personality assessment of employees and their interplay with situational cues, as per conceptualisation of TAT, can assist the corporations towards enhanced levels of employees' behavioural tendencies towards intrapreneurship.
Originality/value
The application of TAT from the present study's perspective is novel theoretically as the literature on the activation of personality traits towards IB outcomes is non-existent. Also, the assessment of situational cues in JA will open avenues for organisational behaviour researchers to seek more organisational situational moderators for their assessment of various personality–outcome relationships in diverse contexts to activate personality traits.

Abstract
Purpose
The determination of human behaviours due to individual characteristics (personality traits) or situational factors has long remained inconclusive. Although the literature stream on personality as the determinants of behaviour is voluminous, the interest of researchers is also growing towards organisational situational cues as the determinant of behaviours. According to situation strength theory (SST), behaviours are determined by situations in strong situations and by personality in weak situations. This study aims to propose a theoretical model of intrapreneurial behaviour (IB) emanation from empowering leadership (EL) by extending the epistemology of SST under the influence of organisational strong situations of job autonomy (JA) and perceived organisational support (POS).
Design/methodology/approach
Using SST, the present study argues that strong situations play a key role in determining human behaviours, and the same can be viewed deductively to assess IB.
Findings
The study attempts to propose whether EL is capable of predicting IB under the strong situation effect of JA and POS while dampening the impact of human personality characteristics.
Originality/value
The current study offers a significant departure from current human resource practices in person-situation dialectics, moving away from personality assessments and toward the creation of cues from strong situations for fostering human behaviour. As a result, personality researchers are being encouraged to conduct a reality check on the extensive personality research conducted in occupational settings. Considering organisational situational cues can impact human resource scope in areas such as talent management, selection, promotion and employment.

Abstract
Purpose
In this study, the situation strength theory (SST) has been applied to assess the predictability of empowering leadership (EL) in explaining intrapreneurial behaviour (IB) under the strong situation effect of job autonomy (JA).
Design/methodology/approach
The proposed theoretical framework was assessed using cross-sectional survey data from 237 engineers employed in Pakistan's automotive firms. Covariance-based structural equation modelling (CB-SEM) was used to analyse the survey data.
Findings
The study's results revealed a positive relationship of EL with JA and IB. Drawing from the conceptualisation of SST, JA serves as an organisational strong situation by offering sufficient cues and significantly intensifies the relationship between EL and IB.
Practical implications
The study contributes by establishing the requirement of strong organisational situations for nurturing IB in organisations. The study's outcomes are useful for academia, practitioners and industry to identify strong situations for employees' organisational behavioural outcomes like IB to dampen the personality impacts of employees on organisational processes. Hence, the study offered a major shift or an alternative in existing human resource practices, from personality assessments to creating cues from strong situations for fostering human behaviours. This will impact organisational human resource management scope during talent management, selection, promotion and employment.
Originality/value
The present study is novel from the IB investigation due to situational response in organisations, as assessed by employees. The study contributes towards SST by extending its epistemology to explain IB as an outcome of EL. The present study offers important empirical evidence for the role of the strong organisational situation of JA.
