This study aims to examine the impact of corporate governance on the speed of adjustment (SOA) of capital structure in a developing market, Pakistan.
Abstract
Purpose
This study aims to examine the impact of corporate governance on the speed of adjustment (SOA) of capital structure in a developing market, Pakistan.
Design/methodology/approach
The study's sample includes 173 non-financial enterprises that were listed on the Pakistan Stock Exchange (PSX) between 2011 and 2020. The capital structure of the sample companies is determined by the ratio of total debt to total debt plus the market value of equity. Corporate governance is measured by board size, independence, CEO duality, management ownership, blockholders ownership and institutional ownership. A two-step difference GMM model was used to achieve the study's objectives.
Findings
Through applying the reduced form model approach, we discovered that corporate governance variables have a considerable negative impact on the speed of targeted leverage adjustment in sample firms. Additionally, to check the robustness of results, the two-stage technique used to examine this corporate governance-SOA relationship. Furthermore, we discovered that smaller enterprises modify their capital structure more than larger firms. Furthermore, corporations prioritize short-term debt adjustment above long-term debt adjustment.
Practical implications
The study's findings provide further information to company managers and investors on the relationship between corporate governance quality and the pace of adjustment towards targeted leverage across Pakistani enterprises. Furthermore, this study adds new information from growing countries such as Pakistan to the existing literature, which can help regulatory authorities and policymakers improve the quality of corporate governance. It is commonly known that improving the quality of corporate governance practices improves the firm's capital structure, which benefits all stakeholders.
Originality/value
In the context of developing economies, the academic literature lacks research that examine the impact of corporate governance on dynamic capital structure decisions. This study intends to fill this gap.

Abstract
Purpose
This study aims to investigate the relationship between corporate governance characteristics and the financial performance of both Islamic and conventional banks in the context of an emerging market, i.e. Malaysia.
Design/methodology/approach
This study includes 300 bank-year observations from Islamic and conventional banks over the period 2010–2021. The dynamic panel model (generalized method of moments [GMM]) was considered the primary estimation model that solves simultaneity, endogeneity and omitted variable problems as most governance variables are endogenous by nature. Hence, static models are considered biased after conducting the DWH test of endogeneity, and considering dynamic panel GMM is valid proven by Sargan and Hensen and first-order (ARI) and second-order (ARII) tests.
Findings
Based on the regression results, the authors discovered that board size, female participation in the board and director remuneration have a significant positive impact on bank performance, whereas board meetings have a significant negative impact. Furthermore, the board governance structure of commercial banks is found to be more passive than that of Islamic banks.
Practical implications
The study’s findings added a new dimension to governance research, which could be a valuable source of knowledge for policymakers, investors and regulators looking to improve existing governance mechanisms for better performance of conventional and Islamic banks.
Originality/value
The goal of this study is to add to the existing literature by focusing on the impact of female board participation and other board governance mechanisms in both conventional and Islamic banks on bank performance.

Abstract
Purpose
The purpose of this study is to understand how servant leadership affects employees’ community citizenship behavior by transforming their servant identity. Additionally, the study explicated whether the relationship between servant leadership and employees’ servant identity is contingent on leader–follower value congruence.
Design/methodology/approach
For this study data was collected from 468 employees working in the service industry in three waves which were undertaken with a lag of one month. The collected data was analyzed through structural equation modeling.
Findings
The results revealed that servant leadership is related to employees’ servant identity. The findings also substantiated the relationship between employees’ servant identity and their community citizenship behavior. The mediating role of servant identity linking servant leadership to employees’ community citizenship behavior was confirmed. Finally, leader–follower value congruence was found to moderate the relationship between servant leadership and employees’ servant identity.
Originality/value
The study is the first to ascertain the mediating role of servant identity linking servant leadership to employees’ community citizenship behavior. It is also the first study to ascertain that the effect of servant leadership on employees’ servant identity is contingent upon leader–follower value congruence.

Abstract
Purpose
The presence of heavy metals in milk causes many acute and chronic physiological dysfunctions in human organs. The present study aims to investigate the heavy metals in cow's and buffalo's milk of two major cities, Karachi and Gujranwala, Pakistan to estimate metal intake by humans from this source.
Design/methodology/approach
In total, 48 milk samples from 2 cities were drawn from animals' udder to avoid contamination. Each sample was digested with nitric acid at 105 oC (degree Celsius) on a pre-heated electric hot plate to investigate the metals by atomic absorption spectroscopy (flame type). Air-acetylene technique analyzed chromium, cadmium and lead, and the hydride method analyzed arsenic in the milk samples.
Findings
The results revealed the highest mean lead concentration (19.65 ± 43.86 ppb) in the milk samples, followed by chromium (2.10 ± 2.33 ppb) and arsenic (0.48 ± 0.73 ppb). Cadmium was not detected in any sample, assuming cadmium's occurrence was below the detection level. The concentrations of all the metals in the samples of the two cities do not differ statistically. Lead concentrations in the buffalo's milk were higher than in cow's milk (p < 0.05). However, the concentrations of arsenic and chromium between buffalo's and cow's milk do not differ statistically. The present study reveals a lower level of metals in the milk than those conducted elsewhere. The mean concentrations of all the metals met the World Health Organization's (WHO) safety guidelines (1993).
Research limitations/implications
Although cadmium causes toxicity in the human body, cadmium could not be measured because cadmium's concentration was below the detection level, which is 1 ppb.
Practical implications
This study will help reduce the toxic metals in our environment, and the sources of heavy metals, particularly from the industrial sector could be identified. The feed and water consumed by the milking animals could be carefully used for feeding them.
Social implications
This study will help reduce the diseases and malfunction of human organs and organ systems since these heavy metals cause toxicity and carcinogenicity in humans. Arsenic and chromium cause cancer while lead causes encephalopathy (a brain disease).
Originality/value
The study reports heavy metal concentrations in the two attributes of four independent variables of raw milk samples that were scarcely reported from Pakistan.

Abstract
Purpose
Sustainability is essential to the ongoing operations of banks, though it is much less clear how Islamic corporate governance (ICG) promotes economic sustainability (ES) and thereby prevents bankruptcy. To explore the unexplored, this study aims to examine the efficacy of ICG in preventing bankruptcy and enhancing the ES of Islamic banks operating in Pakistan.
Design/methodology/approach
The current study measures ES through Altman's Z-score to analyze the level of the industry's stability and consequently examines the effect of ICG on the ES of Islamic banks in Pakistan for the post-financial-crises period. Using the country-level data, this study utilized a fixed-effect model and two-stage least squares (2SLS) techniques on balanced panel data spanning from 2009 to 2020 to provide empirical evidence.
Findings
The empirical results unveiled that board size and meetings have a significant positive influence on the ES while managerial ownership demonstrated an unfavorable effect on ES. Interestingly, the insignificant effect of women directors became significant with the inclusion of controlled variables. Overall, the findings indicate that ICG is an efficient tool for promoting ES in Islamic banks and preventing them from the negative effects of emerging crises.
Practical implications
The findings provide concrete insights for policymakers, regulators and other concerned stakeholders to execute a sturdy corporate governance system that not only oversees the economic, social and ethical aspects but also provides measures to alleviate the impacts of potential risks like the COVID-19 pandemic.
Social implications
Examining the role of ICG in alleviating bankruptcy risk is an informative and useful endeavor for all social actors.
Originality/value
To the best of the authors’ knowledge, this study is one of the first efforts to provide evidence-based insights on the role of ICG in preventing bankruptcy and offers a potential research direction for ES.

Abstract
Purpose
This study examines how project leaders’ knowledge hiding influences project performance via project employee creativity, employing the conservation of resources theory. Further, we investigate how mastery motivational climate (MMC) moderates the project employee creativity and project performance relationship.
Design/methodology/approach
Employing purposive sampling design, two-wave data (N = 245) was collected with a gap of three weeks from employees working in R&D departments in private software development project-based organizations located in Lahore, Pakistan.
Findings
Results suggest that leaders’ knowledge hiding does impede project employee creativity and negatively influence project performance. In addition, MMC was found to accentuate the relationship between project employee creativity and project performance.
Practical implications
This study offers notable insights into the knowledge hiding literature from a top-down perspective within the project management domain relating to IT projects. This study’s findings pose implications for practitioners and project-based organizations who are interested in counteracting the adverse effects of knowledge hiding on project performance.
Originality/value
This study proposes a novel approach to job design by considering resource scarcity caused by a leader’s knowledge hiding as a job demand, along with the achievement goal perspective driven by a mastery or goal orientation. To understand these two perspectives, we rely on the conservation of resources (COR) theory to describe how a leader’s knowledge hiding affects project performance through project employee creativity, moderated by mastery motivational climate.

Abstract
Purpose
Nanofluids are used in technology, engineering processes and thermal exchanges. In thermal transfer processing, these are used for the smooth transportation of heat and mass through various mechanisms. In the current investigation, we have examined multiple effects like activation energy thermal radiation, magnetic field, external heat source and especially slippery effects on a bioconvective Casson nanofluid flow through a stretching cylinder.
Design/methodology/approach
Several studies used non-Newtonian fluid models to study blood flow in the cardiovascular system. In our research, Lewis numbers for bioconvection and the influence of important parameters, such as Brownian diffusion and thermophoresis effects, are also considered. This system is developed as a partial differential equation for the mathematical treatment. Well-defined similarity transformations convert partial differential equation systems into ordinary differential equations. The resultant system is then numerically solved using the bvp4c built-in function of MATLAB.
Findings
After utilizing the numerical approach to the system of ordinary differential equations (ODEs), the results are generated in the form of graphs and tables. These generated results show a suitable accuracy rate compared to the previous results. The consequence of various parameters under the assumed boundary conditions on the temperature, motile microorganisms, concentration and velocity profiles are discussed in detail. The velocity profile decreases as the Magnetic and Reynolds number increases. The temperature profile exhibits increasing behavior for the Brownian motion and thermal radiation count augmentation. The concentration profile decreased on greater inputs of the Schmidt number and magnetic effect. The density of motile microorganisms decreases for the increased value of the bio-convective Lewis number.
Originality/value
The numerical analysis of the flow problem is addressed using graphical results and tabular data; our reported results are refined and novel based on available literature. This method is useful for addressing such fluidic flow efficiently.

Abstract
Purpose
This study aimed to examine how different parenting styles, (maternal and paternal) influence the development of maladaptive schemas in adults with depression. Furthermore, the study intends to explore the mediating role of self-efficacy in the relationship between parenting styles and the development of maladaptive schemas.
Design/methodology/approach
The study’s sample of adults aged 19–35, living in the metropolitan cities of Rawalpindi and Islamabad, Pakistan. The screening process involved the utilization the Urdu version of the Depression Anxiety Stress Scale (DASS-42). Parenting styles were assessed using the Parental Authority Questionnaire, a widely recognized tool that assessing Authoritative, Authoritarian, and Submissive styles. In addition, an Urdu translated version of Schema Mode Inventory was used for emotional and cognitive patterns. Participant’s self-efficacy was assessed using Generalized Self-Efficacy Scale.
Findings
The results revealed that all three paternal parenting styles (authoritative, authoritarian and permissive) significantly impact the development of maladaptive schemas. Similarly, authoritative and authoritarian maternal parenting styles had a significant positive impact on maladaptive schemas, while permissive maternal parenting had a slightly positive impact. Additionally, the study found no significant correlation between self-efficacy and maladaptive schemas.
Originality/value
The current study highlighted the impact of parental involvement both paternal and maternal on the development of maladaptive schema mode among adults with depression with specific focus on the mediating role of self-efficacy. This study tries to enhance the understanding mechanism using the parenting styles contribution in adult mental health.

Abstract
Purpose
We investigate how green transformational leadership (GTL) influences green innovative service behavior (GISB), particularly in the hospitality sector, which faces significant environmental challenges. Drawing from social identity theory (SIT), we introduce green organizational identity (GOI) as a mediating mechanism through which GTL fosters GISB. Furthermore, we propose a moderated mediation model whereby a green knowledge-sharing climate (GKSC) serves as a first-stage moderator to further understand how and when GTL fosters GISB through GOI.
Design/methodology/approach
We employed a multi-study design (i.e. two independent studies across China) to test the hypothesized relationships. Study 1 involved full-time employees from the service industry in China, including healthcare, telecommunication, and insurance sectors (N = 313). Study 2 employed a time-lagged dyadic design, collecting responses from employees and their managers at three different time points in the hospitality sector (N = 419).
Findings
In Study 1, the simple mediation results demonstrate that GTL positively influences GISB through the mediating role of GOI. Moreover, in Study 2, the moderating effect of GKSC was supported, showing that in organizations with strong green knowledge-sharing climate, the indirect effect of GTL on GISB via GOI is amplified.
Originality/value
In our work, we address a critical gap in the literature by identifying both the mechanisms and contextual factors that explain how GTL influences GISB. By introducing GOI as a mediator and GKSC as a first-stage moderator, the study advances understanding of how leadership, organizational identity, and a green-supportive climate interact to promote eco-friendly innovation in service organizations. This contributes both theoretically and practically to the development of effective strategies for advancing green initiatives in the service sector.
