Abstract
Purpose
This study aims to address and observe the positive side of perceived overqualification (POQ) on employee knowledge sharing (KS) and career planning. Role identity theory highlights that an employee’s POQ is related to employee career identity in a positive way.
Design/methodology/approach
The hypotheses were supported by a time-lagged examination of 277 supervisor–subordinate dyads working in the corporate sector.
Findings
The findings state that a person’s career identity is associated with increased KS and career planning. Furthermore, the effect of overqualification on KS and career planning was predicted to be mediated by career identity. Using an interactionism mechanism, this study indicated that this mediation is moderated by leader humility. The career identities of overqualified employees are elevated when a humble leader supports them. The results suggest that, when handled appropriately, POQ may benefit both employees and organizations.
Research limitations/implications
The implications of these results are examined theoretically and practically. Moreover, the findings of this study will open new avenues for scholars and practitioners in the field of organizational behavior and human resource management.
Originality/value
The study examined the positive side of POQ and its effect on employees’ career outcomes and KS attitudes. This study is among the first empirical studies to examine career outcomes and KS behavior due to POQ.

Abstract
Purpose
This work presents a new two-step iterative technique for solving absolute value equations. The developed technique is valuable and effective for solving the absolute value equation. Various examples are given to demonstrate the accuracy and efficacy of the suggested technique.
Design/methodology/approach
In this paper, we present a new two-step iterative technique for solving absolute value equations. This technique is very straightforward, and due to the simplicity of this approach, it can be used to solve large systems with great effectiveness. Moreover, under certain assumptions, we examine the convergence of the proposed method using various theorems. Numerical outcomes are conducted to present the feasibility of the proposed technique.
Findings
This paper gives numerical experiments on how to solve a system of absolute value equations.
Originality/value
Nowadays, two-step approaches are very popular for solving equations (1). For solving AVEs, Liu in Shams (2021), Ning and Zhou (2015) demonstrated two-step iterative approaches. Moosaei et al. (2015) introduced a novel approach that utilizes a generalized Newton’s approach and Simpson’s rule to solve AVEs. Zainali and Lotfi (2018) presented a two-step Newton technique for AVEs that converges linearly. Feng and Liu (2016) have proposed minimization approaches for AVEs and presented their convergence under specific circumstances. Khan et al. (2023), suggested a nonlinear CSCS-like technique and a Picard-CSCS approach. Based on the benefits and drawbacks of the previously mentioned methods, we will provide a two-step iterative approach to efficiently solve equation (1). The numerical results show that our proposed technique converges rapidly and provides a more accurate solution.

Abstract
Purpose
Using two theoretical lenses – social identity theory and generation cohort theory – the present study analyzes the influence of sport motivations (i.e., patriotism, drama and excitement of the game, nostalgic associations, interest in star players and social influence) on the intentions to watch the International Cricket Council (ICC) Twenty-20 (T20) World Cup of three different generation cohorts (i.e., Generations X, Y and Z).
Design/methodology/approach
Data were collected from N = 499 cricket lovers from Pakistan based on a non-probability sampling technique. Exploratory factor analysis (EFA), confirmatory factor analysis (CFA), structural equation modeling (SEM) and multi-group modeling techniques were used as methods.
Findings
SEM results show that cricket fans' intentions to watch the T20 World Cup are positively influenced by patriotism, drama and excitement of the game, and social influence. The results of multi-group modeling reveal significant differences between Generation X-ers, Y-ers and Z-ers regarding the effect of sport motivations on their intentions to watch the ICC T20 World Cup. Specifically, our findings show that for X-ers, interest in star players and nostalgic associations are the main motivations behind watching the T20 World Cup, whereas drama and excitement appeared to be an important predictor for Y-ers, and patriotism and social influence are more likely to increase Z-ers' intentions to watch the T20 World Cup.
Originality/value
This study is the first of its kind to report the motivations of Generations X, Y and Z to watch the T20 World Cup.

Abstract
Purpose
The purpose of this study is to examine the impact of board diversity (e.g. nationality, gender and educational level) on financial performance for a sample of banks listed in 11 countries in the Middle East and North Africa region.
Design/methodology/approach
This paper uses the system generalized method of moments estimation approach on the data of banks listed in the MENA countries over the period 2011–2018 to investigate the relationship between board diversity and financial performance. Also, the findings are supported by additional robustness tests, including ordinary least squares, fixed and random effect techniques.
Findings
The empirical results show that there is a significant relationship between board diversity and financial performance in banks. Specifically, the findings demonstrate that board diversity related to nationality has a significant positive impact on bank performance. The findings also show an insignificant association between gender and educational level diversity and bank performance. The robustness analysis supports the findings of the baseline model.
Practical implications
The study provides multi-country evidence on the importance of board diversity in the MENA region and it sheds light on possible tracks for future reforms aimed at enhancing the effectiveness of the board’s functions.
Originality/value
This paper extends the existing literature by providing empirical evidence on the association between board diversity and financial performance of banks in the MENA countries. This paper also provides preliminary evidence on the importance of board diversity to influence financial performance.

Abstract
Purpose
Diversity in the boardroom is a social factor that spurs public debate in academic and practical arenas. In a two-tier governance system, the question lingers on the impact of board of commissioners and board of directors’ diversity on a company’s performance. This study aims to investigate this issue based on a comprehensive set of diversity variables, namely, age, tenure, gender, education level, culture, functional expertise, industry experience, school of origin and “busyness.”
Design/methodology/approach
The authors constructed diversity indices for board of directors and board of commissioners and used multiple linear regressions to test the hypotheses using samples of companies listed on the Indonesian Stock Exchange from 2014 to 2018.
Findings
Board of director (commissioner) diversity has no significant (a positive) impact on corporate performance. However, the latter does not moderate the relationship between board of director diversity and company performance.
Research limitations/implications
Although the theories of human capital and upper echelons are applied here, the results more likely support a contingency argument, as the effect of diversity may vary by company and period, hence leading to offsetting effects. Thus, the impact of diversity on corporate performance might be better observed through in-depth case studies.
Practical implications
The positive impact of the board of commissioners’ diversity on firm performance might indicate the importance of close monitoring by this board. The results further suggest that appointment decisions of directors and commissioners from diverse backgrounds should be based on criteria other than financial performance.
Originality/value
No study has constructed comprehensive diversity indices of the board of commissioners and directors in a two-tier governance context. The study fills this gap.

Abstract
Purpose
The purpose of the study is to analyze the impact of the Publication Timeline, i.e. Submission to First Decision and Submission to Acceptance on Journal Metrics, i.e. Impact Factor (IF) and 5-year IF.
Design/methodology/approach
Data related to the IF and 5-year IF were retrieved from Clarivate Analytics’ Journal Citation Report 2020. The Publication Timeline of each journal was ascertained through their respective websites. To attain the model fit summary, an analysis of variance (ANOVA) test was performed. Regression analysis was also performed on the models using SPSS 21 software to ascertain the nature and degree of impact the Publication Timeline (Submission to First Decision and Submission to Acceptance) has on Journal Metrics (IF and 5-year IF).
Findings
Submission to First Decision has a significant inverse relationship with both the IF and 5-year IF, whereas Submission to Acceptance has a significant direct relation with 5-year IF and an inverse but insignificant relationship with IF.
Research limitations/implications
Journals published by Springer Nature and of multidisciplinary nature have been considered for the study. Only those journals were selected that provided the information regarding the Publication Timeline, whereas those which did not provide the same, were excluded. However, new insights can be revealed if the journals published by different publishers and belonging to one particular discipline are studied.
Practical implications
The study helps to ascertain the impact of the Publication Timeline on the Impact Metrics of the journals. It can help the authors select the journals as their publishing venues considering the Publication Timeline. Publishers can also be benefitted from the findings of this study since improvisations and modifications in their Publication Timelines can positively influence the impact metrics of their respective journals.
Originality/value
The study attempts to measure the impact of the Publication Timeline on Journal Metrics using cross-sectional secondary data, by performing regression analysis. Though various studies have examined the influence of the Publication Timeline on the IF using correlation analysis, to the best of the authors’ knowledge, this study is the first of its kind to use regression analysis to check the relation, as well as the degree of impact the Publication Timeline, has on Journal Metrics.

Abstract
Purpose
The aim of this study is to provide an insight to international readers into the perspective of doctoral level research in Pakistan. The factors which led to the start of this program and difficulties encountered in this regard at different universities are discussed.
Design/methodology/approach
The study is mainly based on review of the literature. Research theses approved at MPhil and PhD level are evaluated. Some information collected from Library and Information Science (LIS) schools through personal communication is also provided.
Findings
The problems that did not allow success in the doctoral programs in LIS were: lack of encouragement by seniors in a real sense; low esteem for indigenous PhD degree in the eyes of fellow professionals; little or no impact of early recipients of the degree on profession; and non‐availability of financial assistance to the prospective candidates. Of the findings mention is made of: no fixed criteria for admission; the research topics do not concern the problems; and absence of proper supervision/guidance resulting in poor quality of thesis in most cases. Suggestions include: formation of a high level committee comprising senior library educators under the Higher Education Commission to work out problems and streamline the process; maintenance of close links with library schools in other countries, particularly in the English speaking world, which are interested in global librarianship.
Originality/value
This paper is the only evaluation of postmaster level LIS education in Pakistan. The findings are useful for planners of LIS education at postmaster level in Pakistan as well as in other developing countries.

Abstract
Purpose
(1) A mathematical model for the Hybrid nanofluids flow is used as carriers for delivering drugs. (2) The flow conditions are controlled to enable drug-loaded nanofluids to flow through the smaller gap between the two tubes. (3) Hybrid nanofluids (HNFs) made from silver (Ag) and titanium dioxide (TiO2) nanoparticles are analyzed for applications of drug delivery. (Ag) and (TiO2) (NPs) are suitable candidates for cancer treatment due to their excellent biocompatibility, high photoactivity, and low toxicity. (4) The new strategy of artificial neural networks (ANN) is used which is machine-based and more prominent in validation, and comparison with other techniques.
Design/methodology/approach
The two Tubes are settled in such a manner that the gap between them is uniform. The Control Volume Finite Element Method; Rk-4 and Artificial Neural Network (ANN).
Findings
(1) From the obtained results it is observed that the dispersion and distribution of drug-loaded nanoparticles within the body will be improved by the convective motion caused by hybrid nanofluids. The effectiveness and uniformity of drug delivery to target tissues or organs is improved based on the uniform flow and uniform gap. (2) The targeting efficiency of nanofluids is further improved with the addition of the magnetic field. (3) The size of the cylinders, and flow rate, are considered uniform to optimize the drug delivery.
Research limitations/implications
(1)The flow phenomena is considered laminar, one can use the same idea through a turbulent flow case. (2) The gap is considered uniform and will be interesting if someone extends the idea as non-uniform.
Practical implications
(1) To deliver drugs to the targeted area, a suitable mathematical model is required. (2) The analysis of hybrid nanofluids (HNFs) derived from silver (Ag) and titanium dioxide (TiO2) nanoparticles is conducted for the purpose of drug delivery. The biocompatibility, high photoactivity, and low toxicity of (Ag) and (TiO2) (NPs) make them ideal candidates for cancer treatment. (3) Machine-based artificial neural networks (ANN) have a new strategy that is more prominent in validation compared to other techniques.
Social implications
The drug delivery model is a useful strategy for new researchers. (1) They can extend this idea using a non-uniform gap. (2) The flow is considered uniform, the new researchers can extend the idea using a turbulent case. (3) Other hybrid nanofluids flow, in the same model for other industrial usages are possible.
Originality/value
All the obtained results are new. The experimental thermophysical results are used from the existing literature and references are provided.
