Composite materials are effective alternatives for rehabilitating critical members of offshore platforms, bridges, and other structures. The structural response of composite reinforcement greatly depends on the orientation of fibres in the composite material. Joints are the most critical part of tubular structures. Various existing studies have identified optimal reinforcement orientations for a single load component, but none has addressed the combined load case, even though most practical loads are multiplanar.

This study investigates the optimal orientation of composite reinforcement for reducing stress concentration factors (SCF) of tubular KT-joints. The joint reinforcement was modelled and simulated using ANSYS. A parametric study was carried out to determine the effect of the orientations of reinforcement in the interface region on SCF at every 15° offset along the weld toe using linear extrapolation of principal stresses. The impact of orientation for uniplanar and multiplanar loads was investigated, and a general result about optimum orientation was inferred.

It was found that the maximum decrease of SCF is achieved by orienting the fibres of composite reinforcement along the maximum SCF. Notably, the optimal direction for any load configuration was consistently orthogonal to the weld toe of the chord-brace interface. As such, unidirectional composites wrapped around the brace axis, covering both sides of the brace-chord interface, are most effective for SCF reduction.

The findings of this study are crucial for adequate reinforcement of tubular joints using composites, offering a broader and universally applicable optimum orientation that transcends specific joint and load configuration.

The learning outcomes are as follows: to identify and analyze the importance of operations management in a situation demanding minimizing environmental impact and maintaining operational momentum; access the risks faced during project executions and apply project management concepts to facilitate Karachi Steel in implementing indigenous technological solutions; and evaluate the importance of adaptability, continuous improvement and innovation in creating sustainable solutions to address complex challenges.

Javaid Iqbal, CEO of Karachi Steel, was the case’s protagonist. With capacity expansion, Javaid relocated the steel facility from Rawalpindi to Islamabad, Pakistan. The company encountered several difficulties because of the air emissions’ inconvenience to nearby residents and the strict environmental regulations. To push the emissions into the air, the company first installed a locally fabricated chimney. Later, they hired a foreign Pakistani engineering firm to install air filters, but the project proved unsuccessful. To control emissions, the company developed a Wet Particulate Control (WPC) system based on a water-sprinkling mechanism. The endeavor was successful, but it resulted in water pollution. As a result, Karachi Steel signed a contract with a local engineering company that invented and effectively installed an air filtration system. Karachi Steel not only devised solutions for their predicaments but also made significant contributions toward achieving the Sustainable Development Goals (SDGs). However, the emissions reporting and monitoring mechanism continued to cause inconvenience for regulators. In addition, the filtration facility encountered a blocked duct conveying zinc sulfate from smoke, resulting in the periodic suspension of operations. As Karachi Steel seek long-term solutions to current challenges, it is critical to examine the relationship between internal circumstances and external forces and stimulate a holistic approach to resolving issues within the realms of operations management and project management.

Ratees' reactions to performance appraisal (PA) system suggest how effective the system is. However, there is less clarity about those different reactions that good versus poor performing ratees show vis-à-vis their performance appraisals. This paper seeks to examine the possible PA responses (PA fairness and PA satisfaction) of the ratees for the cases where they receive equitable versus equal performance-based rewards and punishments.

Two studies were designed. Study 1 was a scenario-based experiment in Pakistan (N = 100 students) and Study 2 was based on surveys in Japan (N = 123 employed students) and Pakistan (N = 111 full-time working professionals). Data were analyzed using one-way repeated measures (Study 1) and structural equation modeling (Study 2).

Overall, good performers considered PA fairer and more satisfying under equity than under equality. However, poor performers considered PA fairer under equity than under equality.

The study has value for PA theorists and managers, as it offers: (a) an understanding on the differential effect of equity versus equality, on employees' perceptions of fairness and satisfaction in a PA setting; (b) clarity about the likely disparity between good and poor performers' reactions toward perceived fairness and satisfaction; and, (c) ratee reactions from both organizational and social perspectives contributing to the philosophical debate questioning whether both distributive fairness and retributive fairness should operate under similar or different normative principles.

This study aims to identify the psychological factors predicting sociopreneurial intention (SEI) and gain insight into the conversion of SEI to sociopreneurial behaviour (SEB) in the presence of facilitating events (FE) as a moderating factor.

Hypotheses are statistically tested using a partial least square structural equation modelling (PLS-SEM) based on purposive survey data (n = 110) from the leaders of dairy cooperatives in Indonesia. The measurement items are specifically developed for this research after thoroughly analysing the questionnaire items provided by prior studies.

The findings support the hypotheses that empathy (EM), perceived social responsibility (PSR) and self-efficacy (SEFF) are strong predictors of SEI. Moreover, although SEI can be directly converted to SEB, FE significantly moderated that conversion.

Future research should also involve the impact of SEB on the community and the sociopreneurs.

This research empirically examines the influence of external factors in converting SEI into SEB, which prior studies overlooked. Moreover, it involves the leaders of dairy cooperatives in Indonesia who perform SEB to help smallholder farmers’ communities facing dairy farming issues such as capital, milk productivity, land size and others as research participants.

Despite the growing interest in closed-loop manufacturing, there is a lack of comprehensive frameworks that integrate product development, production processes, people and policies (4Ps) to optimize sustainable manufacturing performance. This study investigates the influence of the four Ps of closed-loop manufacturing systems (product development, production processes, people and policies) on sustainable manufacturing performance (SMP).

To investigate the influence of the four Ps on SMP, a hybrid analytical model was employed, combining structural equation modeling (SEM) with artificial neural networks (ANN). Data were collected through a structured survey administered to 353 manufacturing firms in Malaysia. SEM was used to assess the relationships between the variables, while ANN was employed to capture nonlinear relationships and improve prediction accuracy.

The research findings demonstrate that product development practices, including eco-design, life cycle assessment and resource planning, exert the most significant influence on SMP. Furthermore, implementing green and lean manufacturing techniques, energy modeling and material utilization/toxicity planning significantly enhances sustainability outcomes. While the social setting (employee motivation, turnover and work–life quality) does not directly impact SMP, it plays a pivotal role in facilitating the implementation of internal environmental policies. Moreover, environmental management practices, both mandatory and voluntary, serve as intermediaries between the four Ps and SMP within closed-loop manufacturing systems.

The findings offer valuable insights for policymakers, industry leaders and manufacturing organizations. By prioritizing product development, implementing green and lean manufacturing practices and fostering a positive social setting, organizations can significantly enhance their sustainable performance. Additionally, the study highlights the importance of effective environmental management practices in mediating the relationship between other factors and SMP.

This study contributes to the literature by providing a comprehensive framework for understanding the factors that drive sustainable manufacturing performance. The hybrid SEM-ANN model offers a robust and innovative approach to analyzing the complex relationships between the four Ps and SMP.

Drawing on the Job Demands-Resources (JD-R) theory, the primary goal of this study is to conceptualise and empirically validate a theoretical framework that explains the process by which digital job resources influence the innovative work behaviour of technological professionals. Specifically, this study aims to examine the impact of digital job resources, especially digital training, and digital communication, on employee digital engagement. Furthermore, it investigates the influence of digital engagement on digital leadership and the effect of digital leadership on innovative work behaviour. Lastly, the study examines whether digital engagement and digital leadership serially mediate the relationship between digital job resources and innovative work behaviour.

Data were collected from full-time technological professionals using multiple sampling techniques. A total of 307 samples were utilised for the final data analysis. Partial Least Squares Structural Equation Modelling (PLS-SEM), employing SmartPLS 4.0, was used to test the study hypotheses.

The findings of this study emphasize that digital engagement and digital leadership are pivotal in mediating the impact of digital communication on technological professionals' innovative work behaviour. Specifically, our results show that digital communication significantly shapes the digital engagement of these professionals. Digital engagement, in turn, positively influences digital leadership, which then fosters technological professionals’ innovative work behaviour. Notably, both digital engagement and digital leadership serve as mechanisms that link digital communication and innovative work behaviour. Contrary to our initial expectations, the study finds that digital training neither directly affects digital engagement nor has an indirect effect on innovative work behaviour.

The present study is distinct in offering a theoretical framework outlining the steps through which digital resources influence technological professionals' digital engagement, digital leadership capabilities, and their innovative work behaviour. Prior studies have predominantly focused on antecedents of innovative work behaviour, with an emphasis on individual characteristics and organisational environmental factors. There is limited research exploring how, or even if, digital job resources – such as digital training and digital communication – affect employees’ innovative work behaviour. Additionally, the examination of the interrelationship between digital engagement and digital leadership is notably lacking in existing literature. Much of the research has instead probed the converse relationship: how leadership styles impact employees' engagement. Lastly, this research is among the pioneering efforts to consider the serial mediating role of digital engagement and digital leadership between digital job resources and innovative work behaviour, a topic that remains underrepresented in academic discourse. This study addresses these gaps.

Islamic financial technology (fintech), primarily peer-to-peer (P2P) lending, plays a substantial role in funding the unbanked population and small and medium enterprises (SMEs) by offering streamlined financial services through online digital technology. In addition, Islamic fintech lending offers a promising return rate for individual and institutional investors, and therefore, it is considered a worthy investment alternative for diversification. This study aims to examine the determinants of project returns of SMEs on Islamic fintech lending platforms, taking the case study of one Islamic fintech lending platform registered at the Financial Service Authority in Indonesia.

Project return information and other information, such as the name of the SME raising fund, project duration, location, contract (aqad) and value (amount of money) to be raised, were extracted from the Islamic fintech lending platform. Furthermore, a regression analysis was performed using the completed projects as sample data (n = 122) on the platform.

The results show that the rate of return is significantly affected by project duration and type of Sharia-compliant contract. Location and project value are, however, found to be statistically insignificant. This study’s overall results align with the Signaling theory, indicating the importance of information for decision-making.

Due to limited access to the data, our study uses data from one of seven Islamic fintech lending platforms; thus, the study results may not be generalized to the general population.

The results suggest that investors aspiring to invest their funds in SME projects on Islamic fintech lending platforms should consider the project duration and contractual agreement since these factors significantly influence the return. Additionally, society may consider the Islamic fintech lending platform a viable investment instrument since its return rate follows the risk-return principle in classical and established finance theories. That is why Islamic fintech lending platforms are competitive compared to the more established ones, such as the Islamic stock market.

To the best of the authors’ knowledge, this study is the first study using an empirical approach to reveal the project return determinants of SMEs on Islamic fintech lending platform.

This study aims to meticulously examine the current state and operational dynamics of e-libraries in Punjab, Pakistan. Using a qualitative research methodology and strength, weakness, opportunities and threats (SWOT) analysis as a principal analytical framework, the study seeks to capture a detailed portrait of these digital repositories. The goal is to uncover the strengths, weaknesses, opportunities and threats associated with the e-libraries.

A qualitative research approach was chosen to gain deeper insights into the e-libraries in Punjab. The study involved conducting detailed interviews with 14 librarians from these e-libraries, an interview guide that was developed specifically for this study. The guide was refined by experts and validated in a pilot study.

The study reveals that e-libraries in Punjab, Pakistan, excel in providing access to diverse digital resources and enhancing digital literacy but face significant challenges related to infrastructure, hardware and digital skills. Opportunities exist in leveraging mobile technology and enhancing staff training to improve service delivery. However, financial constraints, inadequate skilled personnel and regulatory issues pose threats to their efficacy and sustainability.

This study offers key recommendations for improving Punjab’s e-libraries, such as upgrading infrastructure, enhancing staff training and bolstering cybersecurity. It stresses the need for sustained government funding and support. The findings can help librarians boost digital literacy, refine resources and increase community involvement, while guiding policymakers in shaping effective legal frameworks and practitioners in enhancing resource quality and access.

This research highlights the transformative potential of e-libraries in fostering education and culture in Punjab. It emphasizes integrating technology with community and government support to maximize benefits, bridge digital divides and promote social equity. The study calls for ongoing collaboration among librarians, educators and policymakers to harness e-libraries as catalysts for social change and development.

The originality of this study stems from its innovative application of SWOT analysis to e-libraries in Punjab, a first in this context. This approach not only offers new insights into the operational strengths, weaknesses, opportunities and threats of e-libraries but also significantly aids in strategic planning. The findings are pivotal in shaping decisions that foster the effective use of e-libraries, ultimately enhancing digital literacy and educational growth across the region.

Many studies have explored the relationship between green human resource management practices (GHRM) and employees’ green creative behavior (EGCB) within the hospitality industry. However, most prior studies have relied primarily on mono-method approaches, thereby limiting the depth of understanding about the underlying mechanism through which GHRM impacts employee behavior. The authors, in this paper, aim to argue that the connection between GHRM cannot be universal, and some individual factors will act as boundary conditions between these relationships. The authors employ a mixed-methods research design to address this gap to identify potential boundary conditions.

The authors adopted a two-phase approach, integrating qualitative (study 1) and quantitative (study 2) methodologies. Through qualitative research, the authors uncover valuable insights and construct a framework that is subsequently tested in the quantitative phase.

The findings suggest that the strength of the GHRM-EGCB relationship is contingent on the level of Environmental Specific Psychological Empowerment (ESPE) among employees. Employees with a higher degree of ESPE exhibit a stronger connection between GHRM perceptions and EGCB. Furthermore, the authors identify employees’ altruistic values (EAV) as an important moderator, indicating that the intervening effect of ESPE on the GHRM-EGCB relationship is particularly pronounced among employees with high levels of altruism.

By unmasking the complexity through a mixed-methods design, this study contributes to the existing literature by providing a more nuanced understanding of the mechanism between GHRM and green creative behavior.
