Abstract
Purpose
The purpose of this paper is to advance knowledge of the transformative potential of big data on city-based transport models. The central question guiding this paper is: how could big data transform smart city transport operations? In answering this question the authors present initial results from a Markov study. However the authors also suggest caution in the transformation potential of big data and highlight the risks of city and organizational adoption. A theoretical framework is presented together with an associated scenario which guides the development of a Markov model.
Design/methodology/approach
A model with several scenarios is developed to explore a theoretical framework focussed on matching the transport demands (of people and freight mobility) with city transport service provision using big data. This model was designed to illustrate how sharing transport load (and capacity) in a smart city can improve efficiencies in meeting demand for city services.
Findings
This modelling study is an initial preliminary stage of the investigation in how big data could be used to redefine and enable new operational models. The study provides new understanding about load sharing and optimization in a smart city context. Basically the authors demonstrate how big data could be used to improve transport efficiency and lower externalities in a smart city. Further how improvement could take place by having a car free city environment, autonomous vehicles and shared resource capacity among providers.
Research limitations/implications
The research relied on a Markov model and the numerical solution of its steady state probabilities vector to illustrate the transformation of transport operations management (OM) in the future city context. More in depth analysis and more discrete modelling are clearly needed to assist in the implementation of big data initiatives and facilitate new innovations in OM. The work complements and extends that of Setia and Patel (2013), who theoretically link together information system design to operation absorptive capacity capabilities.
Practical implications
The study implies that transport operations would actually need to be re-organized so as to deal with lowering CO2 footprint. The logistic aspects could be seen as a move from individual firms optimizing their own transportation supply to a shared collaborative load and resourced system. Such ideas are radical changes driven by, or leading to more decentralized rather than having centralized transport solutions (Caplice, 2013).
Social implications
The growth of cities and urban areas in the twenty-first century has put more pressure on resources and conditions of urban life. This paper is an initial first step in building theory, knowledge and critical understanding of the social implications being posed by the growth in cities and the role that big data and smart cities could play in developing a resilient and sustainable transport city system.
Originality/value
Despite the importance of OM to big data implementation, for both practitioners and researchers, we have yet to see a systematic analysis of its implementation and its absorptive capacity contribution to building capabilities, at either city system or organizational levels. As such the Markov model makes a preliminary contribution to the literature integrating big data capabilities with OM capabilities and the resulting improvements in system absorptive capacity.

Abstract
Purpose
The purpose of this study is to look at how Shariah-compliant status and Shariah regulation affect the demand for initial public offerings (IPOs) in Pakistan. The Shariah-compliant status, which is seen as a method that offers a credible signal to investors, may explain the anomaly in IPO demand.
Design/methodology/approach
This research used multivariate and quantile regression models to assess data from 85 IPOs issued on the Pakistan Stock Exchange between 2000 and 2019.
Findings
Shariah-compliant status has a considerable negative association with IPO demand. Nevertheless, there is a considerable positive association among Shariah regulation and IPO demand. Furthermore, the interaction among regulatory quality and Shariah-compliant status has a considerable strong influence on IPO demand. As a consequence, the findings show that Shariah-compliant firms might possibly attract the attention of investors. Investors were found to concur on the amicability of rigorous rules and permissible Shariah-compliance aspects.
Research limitations/implications
Future studies could analyse the financial ratio benchmark (cash and debt) to determine the Shariah-compliant status and Shariah regulation to better understand the problem of IPO demand in the context of Pakistan.
Practical implications
The outcomes of this research are useful for issuers and underwriters in comprehending the characteristics that influence high and early IPO success. Such knowledge may assist issuers and underwriters in responsibly planning and managing the IPO process.
Social implications
The results may be useful to investors looking for critical information in prospectuses to make the best choice when subscribing to IPOs in Pakistan.
Originality/value
This is one of the first studies to provide empirical data on the links among Shariah-compliant status, Shariah regulation and IPO demand in Pakistan. Furthermore, this research demonstrates the interaction impact of regulatory quality and Shariah-compliant status on IPO demand.

Abstract
Purpose
This study aims to focuse on the flow behavior of a specific nanofluid composed of blood-based iron oxide nanoparticles, combined with motile gyrotactic microorganisms, in a ciliated channel with electroosmosis.
Design/methodology/approach
This study applies a powerful mathematical model to examine the combined impacts of bio convection and electrokinetic forces on nanofluid flow. The presence of cilia, which are described as wave-like motions on the channel walls, promotes fluid propulsion, which improves mixing and mass transport. The velocity and dispersion of nanoparticles and microbes are modified by the inclusion of electroosmosis, which is stimulated by an applied electric field. This adds a significant level of complexity.
Findings
To ascertain their impact on flow characteristics, important factors such as bio convection Rayleigh number, Grashoff number, Peclet number and Lewis number are varied. The results demonstrate that while the gyrotactic activity of microorganisms contributes to the stability and homogeneity of the nanofluid distribution, electroosmotic forces significantly enhance fluid mixing and nanoparticle dispersion. This thorough study clarifies how to take advantage of electroosmosis and bio convection in ciliated micro channels to optimize nanofluid-based biomedical applications, such as targeted drug administration and improved diagnostic processes.
Originality/value
First paper discussed “Numerical Computation of Cilia Transport of Prandtl Nanofluid (Blood-Fe3O4) Enhancing Convective Heat Transfer along Micro Organisms under Electroosmotic effects in Wavy Capillaries”.

Abstract
Purpose
A critical factor to the success of IPOs is investor demand, which can be observed from the IPO subscription pattern. Therefore, the objective of this study is to review the studies on the demand of IPOs, including empirical and theoretical literature, due to the substantial growth of IPOs over the last two decades.
Design/methodology/approach
This study extracted secondary data regarding IPO demand published from 1988 to 2022 from the Scopus database. We conducted a meta-literature review for qualitative and quantitative methods on the resulting 284 articles using citation analysis (Harzing’s Publish or Perish and VOS viewer software) and content analysis.
Findings
The findings revealed significant elements of the literature, including countries, institutions, journals, authors, articles and topics. Based on the IPO literature review and analyses, this paper developed future research questions to facilitate an extension of the research. Additionally, this paper developed a dual perspective of the present state of IPO research. First, it asserts that the demand for IPOs is not limited to certain countries, jurisdictions or vintages. Second, there are very few studies on demand for IPOs available despite IPOs’ economic worth.
Originality/value
To the best of the authors’ knowledge, this is the first study of its kind to present an empirical evaluation of demand for IPOs using inclusive mapping.

Abstract
Purpose
The purpose of this study is to examine the associations between board size, board independence and triple bottom line (TBL) reporting. The TBL report consists of three components, namely, environmental, social and economic indices.
Design/methodology/approach
This study’s sample consists of top 50 listed companies from the year 2017 to 2019 on Tadawul Stock Exchange. Ordinary least squares, quantile least squares and robust least squares are used to investigate the associations between board characteristics and TBL reporting, including its separate components.
Findings
The authors find a significant negative association between TBL reporting and board independence. Social bottom line is significantly and negatively related to board size and board independence. Results indicate that board independence negatively influences the TBL disclosure of companies. Therefore, companies are encouraged to embrace TBL reporting. This suggests that businesses should improve the quality of their reporting while ensuring that voluntary disclosures reflect an accurate and fair view in order to preserve a positive relationship with stakeholders.
Originality/value
The present study explains the evidence for the determinants of the TBL in Saudi Arabia.

Abstract
Purpose
This study investigates the variables that impact initial public offerings (IPO) initial returns witnessed in Pakistan from 1996 to 2019 using pre-listing information variables, namely country-level institutional quality, sponsor ownership and pricing mechanism. IPO oversubscription is included as a moderating variable.
Design/methodology/approach
This research is motivated by the premise that the Pakistani IPO market is characterised by a broad range of institutional and regulatory frameworks. Multiple regression studies, i.e. ordinary least square (OLS) and quantile least square (QLS), were performed on 102 IPOs issued on the Pakistan stock market.
Findings
The present study findings suggest that the quality of public service, the independence of civil service from political influences and the legitimacy of government increase investors’ confidence in the prospects of companies, hence increasing the demand for IPO and initial returns. In addition, good regulatory quality enhances market transparency and lowers uncertainty, hence signalling high-quality IPOs and leading in substantial initial returns. The negative effect of the lock-up ratio on the initial return of an IPO is consistent with the risk-return trade-off theory, which asserts that the lock-up ratio indicates the quality of the IPO.
Practical implications
The results provide market regulators, policymakers, investors and underwriters with useful data for assuring proper subscriptions of issued shares, as these variables are crucial for company transparency and market efficiency. The findings will also help investors make better IPO subscription decisions.
Originality/value
The present study explains the important influencing factors of IPO initial return in the Pakistani market.

Abstract
Purpose
Ownership structure deals with internal corporate governance mechanism, which plays important role in minimizing conflict of interests between shareholders and management Ownership structure is an important mechanism that influences the value of firm, financing and dividend decisions. This paper aims to examine the impact of the ownership structures, i.e. managerial ownership, institutional ownership on financing and dividend policy.
Design/methodology/approach
The authors use panel data of manufacturing firms from both developed and developing countries, and the generalized method of moments (GMM) is applied to analyze the results. The authors collect the data from DataStream for the period of 2010 to 2019.
Findings
The authors find that managerial ownership and ownership concentration have significant and positive effects on debt financing, but they have significant and negative effects on dividend policy. Institutional ownership shows a positive impact on financing decisions and dividend policy for sample firms.
Originality/value
This study fills the gap by proving the policy implications for both firms and investors, as managers prefer debt financing, but at the same time try to ignore dividend payment. Therefore, investors may not invest in firms with a higher proportion of managerial ownership and may choose to invest more in institutional ownership, which lowers the agency cost.

The purpose of this paper is to assess the impacts on production of five fruit crops from 1961 to 2018 of energy use, CO2 emissions, farming areas and the labor force in China.
Abstract
Purpose
The purpose of this paper is to assess the impacts on production of five fruit crops from 1961 to 2018 of energy use, CO2 emissions, farming areas and the labor force in China.
Design/methodology/approach
This analysis applied the autoregressive distributed lag-bound testing (ARDL) approach, Granger causality method and Johansen co-integration test to predict long-term co-integration and relation between variables. Four machine learning methods are used for prediction of the accuracy of climate effect on fruit production.
Findings
The Johansen test findings have shown that the fruit crop growth, energy use, CO2 emissions, harvested land and labor force have a long-term co-integration relation. The outcome of the long-term use of CO2 emission and rural population has a negative influence on fruit crops. The energy consumption, harvested area, total fruit yield and agriculture labor force have a positive influence on six fruit crops. The long-run relationships reveal that a 1% increase in rural population and CO2 will decrease fruit crop production by −0.59 and −1.97. The energy consumption, fruit harvested area, total fruit yield and agriculture labor force will increase fruit crop production by 0.17%, 1.52%, 1.80% and 4.33%, respectively. Furthermore, uni-directional causality is correlated with the growth of fruit crops and energy consumption. Also, the results indicate that the bi-directional causality impact varies from CO2 emissions to agricultural areas to fruit crops.
Originality/value
This study also fills the literature gap in implementing ARDL for agricultural fruits of China, used machine learning methods to examine the impact of climate change and to explore this important issue.

Abstract
Purpose
The objectives of this study are twofold. First, it intends to investigate the symmetric link between initial public offering (IPO) variability and the determinants of the stock market index, treasury bill rate, inflation, GDP growth rate and foreign direct investment. Second, this study intends to examine the asymmetric link between IPO variability and the aforementioned determinants, namely the stock market index, treasury bill rate, inflation, GDP growth rate and foreign direct investment.
Design/methodology/approach
Data from 1992 to 2018 were gathered from the country of Pakistan in order to achieve the above objectives. Augmented Dickey–Fuller (ADF) and Phillips Perron (PP) unit root tests were employed to determine the data's stationarity properties. The Auto Regressive Distributive Lags (ARDL) model was utilized to examine the symmetric links, and the Non-Linear Auto Regressive Distributive Lag Model (NARDL) was employed to determine the asymmetric links. While the long-run co-integration was examined using the ARDL bound test, the short-run dynamics were tested using the error correction method (ECM).
Findings
The macroeconomic variables of the stock market index, treasury bill rate, inflation, GDP growth rate and foreign direct investment are found to pose significant short-run and long-run symmetric and asymmetric effects on IPO variability. These results indicate the significance of the aforementioned variables in enhancing IPO variability. The findings also demonstrate the typical reactions of inflation, GDP and FDI towards negative and positive shocks in IPO variability and inflation. This evidence implies that Pakistan's poor capital market development is reflected in the country's weak macroeconomic factors. At the same time, the reduced IPO variability in the country also reflects the lack of confidence among prospective issuers and investors due to Pakistan's weak macroeconomic indicators.
Originality/value
This is the first study of its kind to properly investigate the symmetric and asymmetric effects of the macroeconomic variables on Pakistan's IPO variability.

The purpose of this paper is to investigate the impact of diversification, corporate governance and capital regulations on bank risk-taking in Asian emerging economies.
Abstract
Purpose
The purpose of this paper is to investigate the impact of diversification, corporate governance and capital regulations on bank risk-taking in Asian emerging economies.
Design/methodology/approach
The authors applied the generalized method of moments to analyze a sample of 116 listed banks of ten Asian emerging economies for the years 2010–2018.
Findings
The authors found that diversification, board size, CEO duality and board independence, block holders and capital regulations significantly affect bank risk-taking. In particular, nontraditional income sources such as noninterest income and adoption of diversification strategies minimize bank risk-taking.
Practical implications
It is expected that the outcomes of this study can be used by banks in Asian emerging economies that seek to reduce risk-taking by managing the diversification of their income streams and managing the impacts of capital regulation and implementing sound corporate governance features in monitoring their operations. This study suggests practical risk minimizing strategies for banks. First is the sourcing of nontraditional income and adoption of diversification strategies. Second, maintaining nonexecutive directors on the board would enhance monitoring of business activities. Third, maintaining deposit insurance would reduce bank’s risk. Government provides insurance to depositors to motivate them to deposit their funds into the banks. This, in return, facilitates banks to overcome risk. However, banks need to be cautious of any increase in capital ratio, as channeling funds into risky investments would increase risk.
Originality/value
This study is the first to investigate the impacts of corporate governance, diversification and regulation on bank’s risk-taking in a cross-country setting of ten Asian emerging economies.
