Abstract
Purpose
This research paper aims to explore the influence of social media–based knowledge-sharing intentions (SMKI) on prospective authentic leadership development (ALD) to deal with the future crisis. In the existing literature, to the best of the authors’ knowledge, there is no significant empirical evidence to test the relationship between SMKI and ALD. Thus, this study contributes to the growing literature regarding the role of SMKIs, ALD, social media–based knowledge-sharing behavior (SMKB) and facilitating conditions (FCs). However, in this study, the authors developed a conceptual framework based on technology adoption and leadership theory. It was used to identify preservice educational leaders’ SMKIs and their effect on ALD to deal with an educational crisis during the COVID-19 pandemic. Furthermore, SMKIs are strengthening ALD, directly and indirectly, using SMKB and FCs.
Design/methodology/approach
In this study, the higher education students are considered preservice leaders who were enrolled in educational leadership and management programs. However, this study’s target population and sample are students enrolled in educational leadership and management programs. Therefore, higher education students are considered preservice educational leaders. Therefore, a multilevel questionnaire survey approach was adopted to collect data from preservice educational leaders (n = 451 at Time 1 and n = 398 at Time 2) enrolled in education departments in the selected universities in Pakistan. A total of 398 survey questionnaires were finalized with a return ratio of 89%. The partial least square structural equation modeling with SmartPLS 3.2.8 was used for the data analysis.
Findings
This research found that SMKIs are positively and significantly connected with ALD. This study also confirms that SMKB significantly and positively mediates the relationship between SMKIs and ALD. Therefore, this study concludes that preservice educational leaders were ready to adopt SMKB.
Practical implications
Social media–based knowledge sharing can be helpful to develop authentic leadership among preservice educational leaders during a crisis. Preservice educational leaders as authentic leaders can prove to be an asset in dealing with the COVID-19 pandemic crisis.
Originality/value
This research integrated the technology adoption model and leadership theory to provide empirical evidence of SMKIs’ direct and indirect influence on ALD through social media–based knowledge-sharing actual use behavior by preservice educational leaders during the COVID-19 pandemic. Moreover, the moderated mediating effect of the FCs was also studied in the relationship between SMKIs and actual user behavior as well as ALD.

Abstract
Purpose
The present work is devoted to investigating the sensitivity analysis of the electroosmotic peristaltic motion of non-Newtonian Casson fluid with the effect of the chemical reaction and magnetohydrodynamics through the porous medium. The main focus is on flow efficiency quantities such as pressure rise per wavelength, frictional forces on the upper wall and frictional forces on the lower wall. This initiative is to bridge the existing gap in the available literature.
Design/methodology/approach
The governing equations of the problem are mathematically formulated and subsequently simplified for sensitivity analysis under the assumptions of a long wavelength and a small Reynolds number. The simplified equations take the form of coupled nonlinear differential equations, which are solved using the built-in Matlab routine bvp4c. The response surface methodology and artificial neural networks are used to develop the empirical model for pressure rise per wavelength, frictional forces on the upper wall and frictional forces on the lower wall.
Findings
The empirical model demonstrates an excellent fit with a coefficient of determination reaching 100% for responses, frictional forces on the upper wall and frictional forces on the lower wall and 99.99% for response, for pressure rise per wavelength. It is revealed through the sensitivity analysis that pressure rise per wavelength, frictional forces on the upper wall and frictional forces on the lower wall are most sensitive to the permeability parameter at all levels.
Originality/value
The objective of this study is to use artificial neural networks simulation and analyze the sensitivity of electroosmotic peristaltic motion of non-Newtonian fluid with the effect of chemical reaction.

Abstract
Purpose
This study aims to model the important flow response quantities over a shrinking wedge with the help of response surface methodology (RSM) and an artificial neural network (ANN). An ANN simulation for optimal thermal transport of incompressible viscous fluid under the impact of the magnetic effect (MHD) over a shrinking wedge with sensitivity analysis and optimization with RSM has yet not been investigated. This effort is devoted to filling the gap in existing literature.
Design/methodology/approach
A statistical experimental design is a setup with RSM using a central composite design (CCD). This setup involves the combination of values of input parameters such as porosity, shrinking and magnetic effect. The responses of skin friction coefficient and Nusselt number are required against each parameter combination of the experimental design, which is computed by solving the simplified form of the governing equations using bvp4c (a built-in technique in MATLAB). An empirical model for Cfx and Nux using RSM and ANN adopting the Levenberg–Marquardt algorithm based on trained neural networks (LMA-TNN) is attained. The empirical model for skin friction coefficient and Nusselt number using RSM has 99.96% and 99.99% coefficients of determination, respectively.
Findings
The values of these matrices show the goodness of fit for these quantities. The authors compared the results obtained from bvp4c, RSM and ANN and found them all to be in good agreement. A sensitivity analysis is performed, which shows that Cfx as well as Nux are most affected by porosity. However, they are least affected by magnetic parameters.
Originality/value
This study aims to simulate ANN and sensitivity analysis for optimal thermal transport of magnetic viscous fluid over shrinking wedge.

Abstract
Purpose
The innovative mentality, it has been found that it is poorly addressed, which in turn does not provide clear delineations in academic literature. The innovative mentality is an opposition to the traditional innovative culture and that this is observed indirectly through the new forms of action of the younger generations. The purpose of this study aims to seek to provide answers by analyzing how the innovative mentality of leaders 40 years of age and under impacts the transformational or transactional leadership styles. Second, this research analyzes whether the leadership style used in the “40 Under 40” impacts an innovative organizational behavior that positively drives toward organizational success.
Design/methodology/approach
The partial least squares structural equations method (PLS-SEM) is used to analyze a set of hypotheses to 103 professionals awarded the 40 under 40 of Caribbean Business Magazine in Puerto Rico between 2012 and 2016. The unit of analysis were young professionals recognized as the “40 Under 40” by the Caribbean Business Magazine in Puerto Rico between 2012 and 2016.
Findings
The study results contribute a novel theory about a new style of leadership, based on innovative mentality as a central axis, when combining different leadership styles. The second study examined whether there are significant differences between male and female gender through the proposed research model. The results reflect when the organizational innovative behavior is analyzed, the transactional leadership role used by women is highlighted.
Originality/value
This study distinguishes the “40 Under 40” from other leaders and has allowed their enterprises to be successful is their innovative leadership style, which is executed through their innovative mentality.

Abstract
Purpose
In the presence of informal sector in the country, designing an energy policy and the pursuit of higher economic growth become challenging for emerging economies. These economies are usually resource starved, and the presence of underground economy leads to faulty estimates of energy demand. The authors explore the energy–growth nexus in the presence of underground economy for Pakistan, an emerging economy host to large informal sector and facing recurring energy crises.
Design/methodology/approach
The authors evaluate the impact of underground economy on energy demand in the presence of explanatory variables, including official gross domestic product (GDP), foreign direct investment and financial development. The authors first assess the influence of official economy on the consumption of energy. The authors investigate how energy consumption is influenced solely by underground economy. Finally, the authors evaluate the impact of true GDP on the energy consumption. The authors employ combined cointegration method of Bayer and Hanck (2013) and then apply vector error correction model.
Findings
The results reveal that official GDP, underground economy and true GDP positively and significantly affect energy consumption in both short and long run. Similarly, financial development as well as foreign direct investment enhance energy consumption. The authors find unidirectional causality between energy consumption and official GDP variables (OGDP → EC), underground economy (UE → EC) and true GDP variables (TGDP → EC) in the long run. The authors observe bidirectional causality in the short run between energy consumption and official GDP (OGDP ↔ EC) and true GDP (TGDP ↔ EC).
Originality/value
To the best of the authors' knowledge, no study examines the causal relationship of energy consumption and underground economy. Overall, the findings assist policymakers to consider and implement different energy-related policies considering the significant role of underground economy for energy consumption in Pakistan.

Abstract
Purpose
The purpose of this study is to investigate the links between a company’s position in a corporate network with its financial performance and strategic risk in the context of the largest Central European stock market.
Design/methodology/approach
This study integrates the theory of social network analysis (SNA) with corporate governance theory with a special focus on resource dependence theory. Using the framework of network social analysis, the authors use network measures of social capital and embeddedness.
Findings
The results of studying companies listed on the Polish stock exchange indicate that a company’s corporate network position has a significant negative impact on strategic risk while having no influence on its financial performance. The research also highlights the importance of a firm’s corporate governance model for both performance and strategic risk.
Research limitations/implications
The data collected, and SNA measures used made it possible to conduct a cross-sectional study. Compared to longitudinal studies, this type of study has a couple of disadvantages addressed in the paper. In the future, the dependencies observed in this study should be tested using longer-term data.
Originality/value
To the best of the author’s knowledge, this is the first paper integrating the corporate personal and capital networks to test risk and performance dependencies in the context of Poland’s corporate governance model. The findings and conclusions can also be applied to analyzing Central and Eastern Europe stock markets.

Abstract
Purpose
This study aims to present an analysis on heat transfer attributes of fluid-particle interaction over a permeable elastic sheet. The fluid streaming on the sheet is Casson fluid (CF) with uniform distribution of dust particles.
Design/methodology/approach
The basic steady equations of the CF and dust phases are in the form of partial differential equations (PDEs) which are remodeled into ordinary ones with the aid of similarity transformations. In addition to analytical solution, numerical solution is obtained for the reduced coupled non-linear ordinary differential equations (ODEs) to validate the results.
Findings
The solution seems to be influenced by significant physical parameters such as CF parameter, magnetic parameter, suction parameter, fluid particle interaction parameter, Prandtl number, Eckert number and number density. The impact of these parameters on flow field and temperature for both fluid and dust phases is presented in the form of graphs and discussed in detail. The effect on skin friction coefficient and heat transfer rate is also presented in tabular form. It has been observed that an increase in the CF parameter curtails the fluid velocity as well as the particle velocity however enhances the heat transfer rate at the wall. Furthermore, comparison of the numerical and analytical solution is also made and found to be in excellent agreement.
Originality/value
Although the analysis of dusty fluid flow has been widely examined, however, the present study obtained both analytical and numerical results of power law temperature distribution in dusty Casson fluid under the influence of magnetic field which are new and original for such type of flow.

Abstract
Purpose
The purpose of this study was to assess the knowledge of head and neck cancers (HNCs), their risk factors, signs and symptoms among the general public of Karachi, Pakistan.
Design/methodology/approach
Initially, 503 individuals were approached for data collection, out of which 404 fit the inclusion criteria (response rate = 80.03%). Nonprobability convenience sampling was utilized to select participants who fell under the age group of 15–60 years, barring the fields of Bachelor of Medicine and Bachelors of Surgery (MBBS) and Bachelors of Dentistry (BDS). Knowledge was evaluated by a 9-item questionnaire, the scores of which yielded the following interpretations: No (0), low (1–3), moderate (4–6) and high (7–9) knowledge.
Findings
Of the 404 participants who completed the questionnaire, 357 (88.4%) participants claimed to be aware of HNC. The HNC knowledge scores had a statistical relevance with socioeconomic status (p = <0.01) and level of education (p = 0.02). Most participants recognized a “lump or swelling in the throat” (87.1%) as the most common symptom, followed by “bleeding in mouth or throat” (84.7%). Surprisingly, 75.25% of participants thought HNCs were inclusive of brain cancer.
Originality/value
Overall, knowledge of HNCs among the general public of Karachi surpasses the knowledge in other regions around the world. Our study demonstrated that people indulge in unhealthy habits despite having sufficient knowledge and this warrants prompt interventions and counseling of the people.

Abstract
Purpose
The purpose of this study is to explore the relationships between shared leadership, psychological contract, felt obligation and employees’ creative deviance as well as to investigate the mediating role of psychological contract and the moderating role of felt obligation in these relationships.
Design/methodology/approach
This study used convenience sampling to obtain longitudinal data collected (interval of one week) from 348 frontline hotel employees. The SPSS Process Model 5 was used to test the moderated mediation model.
Findings
The results indicated that shared leadership has a significant positive impact on both employee creative deviance and psychological contract and psychological contract positively influences creative deviance. The results confirmed that the psychological contract mediated the relationship between shared leadership and employee creative deviance. The study also highlighted the moderating role of felt obligation on the relationship between shared leadership and employee creative deviance.
Originality/value
This study contributes to the literature on shared leadership, psychological contract, felt obligation and creative deviance by providing empirical evidence of the mediating and moderating effects of psychological contract and felt obligation on the relationship between shared leadership and employee creative deviance. The findings offer practical insights into how organizations can leverage shared leadership to enhance employee creative deviance through psychological contract and felt obligation.

Abstract
Purpose
Steered by upper echelon theory, this study aims to scrutinize the prevalence of project manager demographic factors (age, education and experience) in project sustainability management and project performance.
Design/methodology/approach
We used a sample of 209 project managers/supervisor/team leaders who were working in the projects of the China-Pakistan Economic Corridor (CPEC).
Findings
The results indicate that project manager demographic factors have a significant influence on project performance (except experience) and project sustainability management. Moreover, project sustainability management partially mediates the relationship between age, education and project performance while it fully mediates the path between experience and project performance.
Practical implications
The research recommends senior, high educated and experienced managers for CPEC who promote sustainability and gain high project performance.
Originality/value
A number of studies have been carried out to assess the relationship between top managers’ attributes and environmental activities. However, so far, none of the studies has paid attention to the CPEC and projects working in Pakistan.
