The purpose of this study is to investigate the relationship between sustainable leadership and sustainable project performance. Specifically, the study aims to examine the mediating role of knowledge integration, examining how knowledge integration within an organization influences project outcomes. In addition, the study seeks to explore the moderating role of top management knowledge values, examining how the values and beliefs of top management influence the relationship between sustainable leadership and project performance.

A three-wave survey of 392 employees working in construction sector projects in Pakistan used both hierarchical regression analysis and Hayes’ PROCESS macro method to evaluate the hypotheses.

The study results show that sustainable leadership positively relates to sustainable project performance and knowledge integration mediating this relationship. In addition, the top management knowledge value moderates the indirect effect of sustainable leadership on sustainable project performance via knowledge integration.

Although the model was tested using three-wave data, it is important to note that the data were obtained from a single source. Therefore, it is possible that common method bias may have influenced the results, and this cannot be disregarded.

Organizations seek to prioritize sustainability and integrate sustainability considerations into their project management processes. Organizations can achieve improved sustainable project performance by investing in sustainable leadership development, fostering a culture of knowledge sharing and learning, prioritizing top management support for sustainable performance and integrating sustainable considerations into project management processes.

The study’s grounding on organizational learning theory adds an original and valuable perspective to the relationship between sustainable leadership and sustainable project performance. This investigation is original, as it combines sustainable leadership, knowledge integration and the moderating role of top management knowledge value to understand their impact on sustainable project performance. This unique approach contributes to the literature by providing new insights into these relationships and mechanisms in the construction industry.

This study aims to assess the nexus between perceived overqualification (POQ), anger, knowledge hiding, cyberloafing and harmonious passion (HP).

The authors obtained 264 responses from two public traded firms in Pakistan using a supervisor-subordinated nested design and a multi-time data collecting strategy using convenience sampling.

The study results indicate that POQ positively affects knowledge hiding and cyberloafing. The authors also found anger as a potential mediator in the direct association between POQ and cyberloafing. In addition, the findings suggest that the association between POQ, knowledge hiding and cyberloafing will be weak when individuals exhibit HP towards their job roles. The results of this research, when considered as a whole, provided support for all of the hypothesised direct and indirect linkages, which has important ramifications for both theory and practise.

This study has both theoretical and practical implications. Grounded on equity theory and relative deprivation theory, this paper asserts that HP should be used to decrease POQ affect. According to the authors, pro-environment employee actions may help build a pro-environment workplace culture as well as a pro-environment sense of responsibility, both of which can help to achieve significant pro-environment results.

This study builds on and fills in the gaps left by earlier research to better aid organisational researchers, practitioners and stakeholders in understanding how POQ, rage, information concealing, cyberloafing and harmonic passion interact with one another.

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.

The hypotheses were supported by a time-lagged examination of 277 supervisor–subordinate dyads working in the corporate sector.

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.

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.

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.

This study investigates the link between servant leadership and project management effectiveness in developmental projects in non-governmental organisations (NGOs). Further, this study examined the mediating role of conflict resolution and moderating role of organisational culture.

A three-wave survey of 288 non-governmental organisation (NGO) employees was used to evaluate the hypotheses. Hierarchical regression analysis and Hayes' PROCESS macro technique were used for data analysis.

In this study, servant leadership positively affects employee project management effectiveness in developmental projects in NGOs, and conflict resolution mediates the relationship. Furthermore, the results show that organisational culture moderates the positive relationship between servant leadership and employee project management effectiveness. Moreover, the authors investigated the hypotheses via a moderation mediation model. The strength of the mediated link between servant leadership and project management effectiveness (via conflict resolution) depends on organisational culture strength.

Leaders that practice servant leadership care for their employees genuinely and serve them by allowing them to make their own decisions. Every organisation may benefit from this leadership style since it encourages project effectiveness

New empirical data from this study suggests that servant leadership positively and substantially affects employee project management effectiveness in developmental projects in NGOs.

This paper aims to study the stagnation point flow of Al₂O₃–Cu/H₂O hybrid nanofluid over a radially shrinking disk with the imposition of the magnetic field, viscous-Ohmic dissipation and convective boundary condition.

Similarity variables are introduced and used in reducing the governing partial differential equations into a system of ordinary differential equations. A built-in bvp4c solver in MATLAB is then used in the computation of the numerical solutions for equations (7) and (8) subject to the boundary conditions (9). Then, the behavior of the flow and thermal fields of the hybrid nanofluid, with various values of controlling parameters, are analyzed.

The steady flow problem resulted in multiple (dual) solutions. A stability analysis performed to identify the stable solution applicable in practice revealed that the first solution is stable while the second solution is unstable. The skin friction coefficient and Nusselt number of the hybrid nanofluid are found to be greater than the Al₂O₃–H₂O nanofluid. Thus, the hybrid nanofluid has a better heat transfer performance than the nanofluid. Besides that, the presence of the magnetic field, suction, convective boundary condition and the enhancement of nanoparticle volume fraction of Cu augments the skin friction coefficient and Nusselt number of the hybrid nanofluid. Meanwhile, the presence of viscous-Ohmic dissipation reduces the heat transfer performance of the fluid.

To the best of the authors’ knowledge, the present results are original and new for the study of the flow and heat transfer of Al₂O₃–Cu/H₂O hybrid nanofluid past a permeable radially shrinking disk. Considerable efforts have been directed toward the study of the boundary layer flow and heat transfer over stretching/shrinking surfaces and disks because of its numerous industrial applications, such as electronic, power, manufacturing, aerospace and transportation industries. Common heat transfer fluids such as water, alumina, cuprum and engine oil have limited heat transfer capabilities due to their low heat transfer properties. In contrast, metals have higher thermal conductivities than these fluids. Therefore, it is desirable to combine the two substances to produce a heat transfer medium that behaves like a fluid but has higher heat transfer properties.

Limited evidence exists on bacha bazi, Afghanistan's steadily revived practice involving transgenerational same-sex relationships, despite its frequent association with violence towards young males, known as bacha bereesh. This paper aims to fill this critical gap.

The author conducted an integrative literature review using qualitative and quantitative secondary data. An ecological framework for violence was applied to the findings.

The findings offer a comprehensive overview of bacha bazi in its modern form, including the unique health needs, sexual practices, and gender identities and orientations of bacha bereesh. The author reveals how Afghan masculine identities and male-male sexual activity occur in relation to power structures and notions of honor. Numerous risk factors increasing bacha bereesh vulnerability for violence and socio-legal barriers constraining access to crucial services are also discussed.

Afghanistan's shame-based culture limits accurate data collection by obscuring the practice and stigmatizing bacha bereesh who serve in feminized roles.

The research highlights the inadequacies of applying Western gender-binary frameworks to bacha bazi. It contributes to our understanding of sexuality, gender, masculinity, and male-directed sexual violence within Afghan culture. These insights will help us better address the health needs of this underserved population.

The lack of evidence addressing these topics highlights our paper's originality, while the literature firmly linking violence to poor physical and psychological health outcomes emphasizes the importance of its contribution.

The need to address energy management as a significant innovation in the smart grid is emphasized to enable a more effective penetration of renewable energy to achieve energy savings and CO₂ emission reductions. The purpose of this study is to propose a holistic, flexible decision framework for energy management in a smart grid.

According to the situation actor process−learning action performance (SAP−LAP) model, the variables have been identified after a comprehensive analysis of the literature and consideration of the opinions of domain experts. However, the importance of each SAP−LAP variable is not the same in real practice. Hence, focus on these variables should be given based on their importance, and to measure this importance, an interpretive ranking process based ranking method is used in this study. This helps to allocate proportionate resource to each SAP−LAP variable to make a better decision for the energy management of the smart grid.

This study ranked five actors based on their priorities for energy management in a smart grid: top management, generator and retailor, consumers, government policy and regulation and technology vendors. Furthermore, actions are also prioritized with respect to performance.

The SAP−LAP model conveys information about the state of energy management in India to actors who may proceed or manage the flow of electricity. Additionally, this study aids in detecting vulnerabilities in the current energy generation, transmission and distribution technique. The synthesis of SAP results in LAP, which assists in recommending improvement actions learned from the current situation, actors and processes.

The SAP−LAP model is a revolutionary approach for examining the current state of energy management in a unified framework that can guide decision-making in conflicting situations, significantly the contradictory nature of India’s renewable energy and power sectors.

Teacher Education has been transforming throughout the world to cater to the emerging needs of quality education. Significant developments have taken place nationally and internationally in political, economic, and cultural fields, influencing education in general and teacher education in particular. The quality of education depends to a great extent on the quality of teachers. And, the quality of teachers depends on the way they are educated and trained. Pakistan has a vast education sector and a huge teaching force but teacher education in the country has not been keeping pace with modernization and development globally. Teacher education curricula, dissemination, evaluation and implementation revolved around traditional models for decades. However, there has been a growing realization to reform the teacher education system lately. The education policy (2009) of Pakistan indicates such realization on the part of the stakeholders. This chapter reports on an important teacher education reform program, which is based on collaboration between the government of Pakistan and the USAID. The Teacher Education Project (TEP), assisted by USAID, is a reform initiative that aimed at restructuring and modernizing teacher education in Pakistan. This chapter aims to provide insights into the objectives, importance and achievements of the project in terms of shaping the future direction of teacher education in Pakistan. It reports on the substantial structural and policy changes that took place in teacher education under the project. This chapter also highlights the possible challenges in the way of useful implementation and sustainability of this and similar education reform initiatives in Pakistan.

There is growing recognition that effective project control systems (PCS) are critical to the success of projects. The relationship between the individual elements of PCS and successfully achieving project objectives has yet to be explored. This research investigates the enablers and barriers that influence the elements of PCS success and drive project objectives.

This study adopts a mixed approach of descriptive analysis and regression models to explore the impact of six PCS elements on project outcomes. Petroleum and chemical projects in Saudi Arabia were selected as a case study to validate the research model.

Data from a survey of 400 project managers in Saudi’s petroleum and chemical industry reveal that successful PCS are the key to achieving all project outcomes, but they are particularly critical for meeting project cost objectives. Project Governance was identified as the most important of the six PCS elements for meeting project objectives. A lack of standard processes emerged as the most significant barrier to achieving effective project governance, while having skilled and experienced project team members was the most significant enabler for implementing earned value.

The study offers a direction for implementing and developing PCS as a strategic tool and focuses on the PCS elements that can improve project outcomes.

This research contributes to project management knowledge and differs from previous attempts in two ways. Firstly, it investigates the elements of PCS that are critical to achieving project scope, schedule and cost objectives; secondly, enablers and barriers of PCS success are examined to see how they influence each element independently.

This paper aims to investigates a novel design of a modular moving magnet linear oscillating actuator (MMM-LOA) with the capability of coupling modules, based on their application and space requirements.

Proposed design comprised of modules, and modules are separated by using nonmagnetic materials. Movable part of the proposed design of LOA is composed of permanent magnets (PMs) having axial magnetization direction and tubular structure. Stator of the proposed design is composed of one coil individually in a module. Dimensions of the design parameters are optimized through parametric analysis using COMSOL Multi Physics software. This design is analyzed up to three modules and their response in term of electromagnetic (EM) force and stroke are presented. Influence of adding modules is analyzed for both directions of direct current (DC) and alternating input loadings.

Proposed LOA shows linear increase in magnitude of EM force by adding modules. Motor constant of the investigated LOA is 264 N/A and EM force per PM mass is 452.389 N/kg, that shows significant improvement. Moreover, proposed LOA operates in feasible region of stroke for compressor application. Furthermore, this design uses axially magnetized PMs which are low cost and available in compact tubular structure.

Proposed LOA shows the influence of adding modules and its effect in term of EM force is analyzed for DC and alternating current (AC). Moreover, overall performance and structural topology is compared with state-of-the-art designs of LOA. Improvement with regard of motor constant and EM force per PM mass shows originality and scope of this paper.
