Abstract
Purpose
In this article, we consider the magnetohydrodynamic (MHD) nanofluid flow over a rotating stretchable disk through porous medium. For porous medium, Darcy’s relation is used. It also encompassed the impact of nanoparticles shape on MHD nanofluid flow and heat transfer. The effect of thermal radiation and Joule heating is also being considered.
Design/methodology/approach
Three categories of nanoparticles are taken into deliberation, i.e. copper, silver and titanium oxide. The nanofluid is made of pure water and various types of sphere- and lamina-shaped nanoparticles. By using appropriate similarity transformation, the governing partial differential equations are transformed to ordinary one. The coupled ordinary differential equations system is tackled numerically by bvp4c method.
Findings
The impact of various pertinent parameters, i.e. solid volume fraction, Hartman number, thermal radiations parameter, Reynolds number, Eckert number, porosity parameter and ratio parameter, on flow and Nusselt number with a fixed value of Prandtl number at 6.2 is discussed in details. The obtained results are presented in the concluding section. The lamina shape of nanoparticles in silver-water performed an excellent role on temperature distribution. The heat transfer rate of lamina shape in copper-water was found to be greater in the system of flow regime.
Originality/value
The authors have discussed the shape effect of nanoparticles on MHD nanofluid flow over a rotating stretchable disk through porous medium using three categories of nanoparticles, such as copper, silver and titanium oxide. To the best of the authors’ knowledge, this is the first study on mass and heat transfer nanofluid flow and no such study is yet published in literature. A detailed mathematical analysis has also to be carried out to prove the regularity of model. The authors believe that the numerical results are original and have not been copied from any other sources.

Abstract
Purpose
This study aims to investigate how the management of supply chain information impacts the performance of the supply chain. This relationship is explored by considering the mediating influence of internal and external integration, which is underpinned by the principles of resource-based theory.
Design/methodology/approach
Data was collected from 144 supply chain professionals across different manufacturing companies. The proposed hypotheses were subjected to quantitative analysis using partial least squares structural equation modeling, and the validity of the measurement model was assessed with the assistance of SmartPLS software.
Findings
This study identified that information management (IM) significantly and positively affects internal integration (II), customer integration (CI) and supply chain performance (SCP). Similarly, the results showed that II significantly and positively affects SCP. Likewise, CI positively and significantly affected SCP. At the same time, II found a positive yet significant mediating role in the relationship between IM and SCP. CI was found to play a positive but insignificant mediating role in the relationship between IM and SCP.
Originality/value
This research evaluated a second-order model and tested the SCP in conjunction with the resource-based view in the manufacturing industry. This research could be beneficial for researchers, manufacturers and policymakers to attain organizational objectives by implementing an efficient IM system for better integration and SCP.

Abstract
Purpose
Financial shenanigans are the omissions or actions undertaken with the purpose of misrepresenting an organisation's financial statements. Many examples now exist of such behaviour emerging in the context of a desire to deceive the users of financial reports. In this context, research has illustrated how investors can find themselves impacted by such behaviour, with incorrect decision-making around investment decisions being a major issue. However, auditors' perspectives, of obvious importance in such scenarios, given these individuals' role in attesting to the veracity of financial disclosures, have not been investigated. The aim of this study is to address this gap by seeking the experiences of auditors in the developing nation of Pakistan, an environment in which the significant impact of financial improprieties is well-documented.
Design/methodology/approach
Interviews with 50 Pakistani-based auditors were conducted to gather perceptions about the nature and prevalence of financial shenanigans. The questions posed were structured to address issues relating to both the drivers of and methods used to operationalise financial malfeasance.
Findings
The views expressed by the participants suggest that this type of malpractice is common, with a variety of forms employed and a level of audacity and shamelessness is striking. The results indicate the absence of the three institutional pillars conventionally associated with motivating organisational attempts to legitimise behaviour and maintain social contracts. When considered alongside recent findings that the audit profession in Pakistan may not always play an effective monitoring role, we argue that the evidence suggests the existence of motivations for legitimising strategies are not yet fully understood.
Research limitations/implications
This contention helps address recent calls for investigation of issues around legitimising tendencies where theoretical understanding is incomplete. A full understanding of the embedded practices will provide capital providers with the opportunity to make more informed decisions regarding their investments in Pakistani firms by highlighting the financial shenanigans involved, including the sheer audacity apparently associated with the observed behaviour.
Originality/value
Earnings management and auditing have not been studied widely in Pakistan despite the abundant and persistent nature of corporate scandals across the nation for many decades. Whilst implementation (and enforcement) of some accounting and auditing standards have taken place recently, the financial collapses continue, and understanding regarding the on-going fraud is urgently needed. The extent and shameless nature of the perceived behaviour are striking, suggesting that those closest to financial reporting in Pakistan see fraudulent financial reporting as being close to, if not yet fully representative of, normal practice.

Abstract
Purpose
This study aims to explore how organisations use institutional language in Green Bond reports to explain and justify their activities using language that describes and reflects narratives while simultaneously constructing and shaping ideology. The paper mobilises Wodak and Meyer’s critical discourse analysis (CDA) to examine reports and related documentation relating to Green Bonds issued in France.
Design/methodology/approach
The study uses three legitimating discourses: technocratic, environmental and social and business performance to develop a linguistic perspective that permits contributions to existing knowledge in the area.
Findings
The analysis attempts to identify the discursive strategies used to legitimise Green Bond issuance via claims linked to environmental management improvements and business activities’ social impact.
Originality/value
The study contributes to the critical literature on organisational legitimation and responsibility, investigations of Green Bond narratives and an understanding of broader environmental reporting in the financial sector.

Abstract
Purpose
This paper aims to explore the use and impact of social media, specifically Twitter (now X), in political mobilization in Pakistan. It focuses on the events followed by the no-confidence motion against Imran Khan as Pakistan’s prime minister in April 2022 and the protest campaign that ensued, facilitated through the strategic use of the Urdu hashtag #امپورٹڈ_حکومت_نامنظور (translated as “imported-government unacceptable”) on Twitter, both within and outside Pakistan.
Design/methodology/approach
Using Web scraping, data from Twitter was extracted and analyzed between 2022 and 2023. By probing into user account profiles and interactions with this hashtag, this paper investigates the claims surrounding the hashtag’s popularity, by identifying suspicious accounts and their contributions in the trending of the hashtag.
Findings
Findings suggest that the claim of the hashtag's unprecedented success was overhyped, further suggesting that the popularity and impact of the social media campaign were exaggerated. Despite high engagement rates, the study indicates a discrepancy between perceived influence and actual impact on public sentiment and political mobilization.
Originality/value
This paper contributes to the literature on social media’s role in political mobilization and agenda-setting in the Pakistani context. More generally, understanding hashtag dynamics and their impact on shaping public opinion, may be beneficial to academics and practitioners in better understanding the role of digital platforms in the politics.

The purpose of this study is to develop a financial performance measurement model for real estate business.
Abstract
Purpose
The purpose of this study is to develop a financial performance measurement model for real estate business.
Design/methodology/approach
The study uses balanced scorecard (BSC) proposed by Kaplan and Norton (1996) as a theoretical support. The study, being exploratory in nature, uses survey method to collect data on several dimensions of BSC as well as on other performance measures used by real estate businesses in India. The survey data collected is analyzed using exploratory factor analysis (EFA) to explore the model constructs. This is followed by building an integrated conceptual model for measuring the financial performance of a real estate business. The model is tested using partial least squares structural equation modeling (PLS-SEM).
Findings
The study finds that the financial performance of the real estate business revolves around customer satisfaction, employee satisfaction and external networks. The right alignment of these components lead to superior financial performance. It also provides a competitive advantage to the real estate business. These three components (customer satisfaction, employee satisfaction and external networks) have direct and indirect influences on the financial performance of real estate business.
Research limitations/implications
A small sample size (78 respondents), as well as the respondent’s geographical concentration in India, are the limitations of the study. Hence, generalization of findings may be difficult until the findings are validated across the globe.
Practical implications
The conceptual performance measurement model suggested in this research provides an effective tool to plan and strategize to achieve superior financial performance, particularly for stakeholders in the real estate business.
Originality/value
To the best of the authors’ knowledge and belief, this is the first attempt to develop a comprehensive financial performance measurement model for real estate business and test it using EFA and PLS-SEM.

Abstract
Purpose
This study aims to examine the environmental impact of fossil fuel use in newly industrialized countries (NICs), focusing on the relationship between economic growth, energy consumption and environmental sustainability from 1971 to 2020.
Design/methodology/approach
The research uses pool mean group autoregressive distributive lag, fully modified ordinary least squares and dynamic ordinary least squares econometric models to analyze long-run data. These methods enable a detailed assessment of how economic and industrial factors affect environmental pollution.
Findings
The study finds that nonrenewable energy consumption is positively linked to environmental pollution, with a 1% increase leading to a 6.25% rise in pollution. Industrialization, urbanization and globalization also significantly increase pollution, with increments of 2.51%, 3.97% and 2.11%, respectively. Conversely, economic growth has a beneficial effect, reducing pollution by 2.59% for every 1% increase in growth.
Practical implications
Policymakers should balance economic growth with environmental sustainability by reducing nonrenewable energy consumption and supporting renewable energy adoption.
Originality/value
This research provides fresh insights into the dynamics between economic growth and environmental pollution in NICs. By using advanced econometric techniques over an extended period, it offers a view of how economic and industrial activities influence environmental outcomes, highlighting the dual role of economic growth in both promoting development and reducing pollution.

This study aims to examine the relationship between board capital and firm performance in the Chinese tourism industry.
Abstract
Purpose
This study aims to examine the relationship between board capital and firm performance in the Chinese tourism industry.
Design/methodology/approach
The study’s sample includes firms from the Chinese hotel, air transportation/travel and catering industries. This study explores the governance environment in tourism industries. This study estimates three dimensions of the board, including education, expertise and directors interlock. These dimensions are further grouped as human capital (i.e. education and expertise), social capital (interlocks) and board capital (sum of social and human capital). Ordinary least square regressions with multiple robustness tests are used to investigate the effect of board capital on firm value in Chinese listed tourism firms during 2005–2018.
Findings
This study finds that board capital positively impacts firm performance in its dimensions of human and social capital. This study also highlights the two important ownership contexts, namely, institutional investors and state-ownership, that shape the board capital-firm performance association in the Chinese tourism industry.
Practical implications
The findings suggest that board capital plays a significant role in corporate decisions. The results illustrate that higher board capital improves both governance mechanisms and resource provision roles of the board, resulting in higher firm value. The results further offer implications for managers and shareholders of tourism firms when electing directors as shareholders’ representatives.
Originality/value
The study has two important contributions. First, it extends the prior literature of firm value by considering the board’s human and social dimensions in the tourism sector. Second, contrary to prior research on board, this study takes three facets of board capital, education, expertise and interlocks that improve governance mechanisms and bring new resources in the shape of skills, knowledge and expertise.

Abstract
Purpose
The purpose of this study is to examine the role of knowledge management practices, organisational commitment and capacity building on employee performance in the hotel industry. This study also investigated the mediating role of organisational commitment and capacity building between knowledge management practices and employee performance.
Design/methodology/approach
A quantitative approach and questionnaire survey were used to collect data from hotel employees from Malaysia. Self-administered questionnaires were distributed to collect data from 291 participants, and partial least squares structural equation modelling was used to analyse the hypotheses.
Findings
The results of this study confirm that knowledge management practices positively and significantly affect knowledge-employee performance. Employees achieve this performance through the mediating influence of organisational commitment and capacity building culture.
Practical implications
This study offers several implications for Malaysian practitioners and policymakers regarding learning and knowledge management practices in the hospitality industry. The results suggest that organisations can manage knowledge assets and key processes of the organisational environment to create and use knowledge to improve sustainable employee performance through knowledge management practices.
Originality/value
This study sheds light on the knowledge management literature by examining the effect of knowledge management practices on organisational commitment, particularly in the hospitality industry in Malaysia.
