In the field of education, ongoing processes, and optimal schoolwork outcomes require educational leadership, especially in developing countries, due to the lack of sustainable teaching performance and effective leadership. The present study aims to examine the mediating role of teachers’ commitment to transformational leadership and sustainable teaching performance. The sample of the study was selected using a stratified random sampling technique. Out of the 450 copies distributed to the participants, only 374 were retrieved as valid. The hypotheses of the study were tested using PLS–SEM. The findings showed a positive effect of transformational leadership on teachers’ commitment. Moreover, transformational leadership was also found to positively impact teachers’ performance. In contrast, the teachers’ commitment was revealed to positively affect sustainable teaching performance. Finally, the study showed that the teachers’ commitment mediated the relationship between transformational leadership and sustainable teaching performance. This study is unique for being among the few studies that examine the effects of principals’ transformational leadership. It provides educational leaders and policymakers with significant insights by providing a roadmap that aids in understanding the most influential factors on teaching performance sustainability. Consequently, this study holds significant practical relevance for leaders in the field of education and policymakers, as they provide valuable insights into policies and practices that can be implemented to foster sustainability in the school environment.

This study intends to bridge the unattended research gap and add to the knowledge base of ‘human resource management’ regarding the relationships between abusive supervision, and individual organizational citizenship behaviour (OCBI), through the mediation of ‘employee well-being’. For the given purpose, a sample of 250 cases was selected to collect data from non-managerial hotel employees from the metropolitan cities of Pakistan. Given responses were analysed in Smart PLS 3.0. Structural equation modelling (PLS-SEM) was used to conduct the necessary tests regarding measurement model and structural model assessment. The study found statistical support for three of the four hypotheses, confirming the deleterious role of abusive supervision in general and the intervening role of employee well-being. The findings have concluded that abusive supervision is harmful for workplaces, particularly when it comes to employees’ citizenship behaviours. Finally, the predictive relevance and r-squared values for the underlying model were also confirmed.

The present consumer behavior is manipulated by “fast fashion”, where purchasing new, trendy, affordable clothes is preferred over recycling old ones. This changing mannerism has escalated the GHG emissions from the fashion industry. Energy-intensive raw material production, preparation, and processing contribute to considerable emissions. The management of the returned goods from the primary market and further processing through the secondary outlets indulge in reverse logistics. In this paper, efforts are made to minimize the total cost and the carbon emission amount during the process of managing the return articles from the primary market to the reverse distribution center, further processing of the articles at the secondary outlet, and the return of the unsold or excess articles from the secondary outlet. Reverse cross-docking has been implemented in managing the return articles, while environmental concerns over GHG emissions have been addressed by investing in green technology under a strict carbon cap policy. In this research, return articles from the primary and secondary markets, rework of the returned articles, and disposal of the impaired returned articles have been considered. The carbon emission cost at all stages of transportation, rework, or disposal has also been incorporated into this model. A constrained mixed integer linear programming model is proposed and solved considering green investment. A numerical example has been formulated to investigate the effect of green technology on the total cost. The results portray that, though the total cost increases by nearly 2% due to investment in green technology, it ensures a considerable drop of 23% in the carbon emission amount. Also, the result is successful in establishing that reverse cross-docking is a better option than traditional warehousing in terms of minimizing the cost.

To scientifically address the low productivity issue of traditional solar desalination systems, the current review intends to investigate the effect of design changes and performance improvement of solar stills with external and internal condensers. This review highlights that elements such as coolant techniques, the geometry of the condenser, and material features (e.g., nanofluids or surfaces of wettability) have a pivotal impact on maximising output. The results show that the combination of external condensers in solar stills is remarkably effective, where the efficiency ranges between 24% and 165% in distillate yield depending on the design modifications, which include the use of nanofluids, reflectors, and phase change materials (PCMs). In this regard, internal condensers explicitly display significant performance advances, with water production improvements of more than 150% in improved stepped designs and 60% in capillary film designs. To guarantee the maximum production of fresh water, this review proposes a number of adjustments to elevate the overall performance of solar stills, such as condensers with enhanced mechanisms of heat transfer or passive cooling strategies, which enable solar stills to be more practical in achieving the sustainable desalination of water across a wide range of climatic regions. Indeed, the enhancement of the efficiency of solar desalination technologies would support the United Nations Sustainable Development Goal 6 (Clean Water and Sanitation), providing access to safe and affordable drinking water for all.
