Opis: Background and Purpose: Organisational politics can have a substantial negative effect on employees’ performance, however many organisations still do not pay attention to this organisational behaviour. In our study, we aim to examine the relationship between organisational culture and organisational citizenship behaviour through how employees perceive political behaviour within organisations. Methods: Convenience sampling technique has been employed, quantitative data were collected from 532 employees in the Jordan banking industry via online surveys. Structural equation modelling (SEM) was employed to test the hypotheses of the study. Results: Analyses showed that organisational culture within the banking industry has an effect on how employees perceive political behaviour. A negative perception of political behaviour by employees, in turn, has a negative influence on employees’ citizenship behaviour. These findings answer previous calls to investigate the destructive effect of organisational politics on employee outcomes. Conclusion: Organisations should pay more attention to the destructive effect of organisational politics and try to minimise such behaviour. Organisational citizenship behaviour, in contrast, benefits organisational performance, and the enhancement of this is recommended through the implementation of more effective policies and strategies.

Opis: Purpose: The purpose of this study is to examine how employee perceptions of corporate social responsibility (CSR) can enhance creative performance in an organization both directly and indirectly through job satisfaction and organizational citizenship behavior. This will allow organizations to consider the different factors influencing creative performance, and how these factors can be utilized in a beneficial manner for the organization. Methods: The data for this study was collected via a survey among three telecommunication companies. The valid responses amounted to 344 junior employees. The data was then analyzed to test the hypotheses through structural equation modeling (SEM). Results: The findings of this study indicated a direct positive significant relationship between employee CSR perceptions and creative performance. As well as a positive correlation between employee CSR perceptions and extrinsic and intrinsic job satisfaction. Furthermore, supporting the indirect effects of job satisfaction and organizational citizenship behavior. Moreover, a positive correlation between job satisfaction and organizational citizenship behavior was found. Finally, organizational citizenship behavior and creative performance showcased a positive correlation as well. Conclusion: Organizations should consider the impact of employee CSR perceptions on creative performance, indirectly through extrinsic and intrinsic job satisfaction and organizational citizenship behavior to achieve higher levels of creative performance within their organizations.

Opis: This study explores the potential of using basalt reinforced UHPC by incorporating simulta- neously self-cleaning and self-luminescent features, paving the way for sustainable advancements in civil engineering. New green formulations of UHPC were developed by integrating supplementary cementitious materials and optimizing water to the binder ratio, followed by using basalt fibers to enhance strength and ductility. The fabricated samples with high particle-packing density exhibit sufficient workability and compressive strength up to 136 MPa, and, when incorporating basalt fibers, a notable reduction in brittleness. The inner microstructure of basalt fibers was observed to be smooth, homogeneously distributed, and well adhered to the UHPC matrix. To ensure the desired long-lasting visual appearance of decorative UHPC and reduce future maintenance costs, a time-effective strategy for creating a light-emitting biomimetic surface design was introduced. The samples exhibit high surface roughness, characterized by micro to nano-scale voids, displaying superhydrophobicity with contact angles reaching up to 155.45◦. This is accompanied by roll-off angles decreasing to 7.1◦, highlighting their self-cleaning features. The self-luminescence feature showcased intense initial light emission, offering a potential energy-efficient nighttime lighting solution.

Opis: Reducing the iridium content while preserving high OER activity is an important prerequisite for the progress of inexpensive anodic water splitting electrocatalysts in low pH medium. Here we report the effects of bulk and surface structures of antimony doped tin oxide (ATO) supports on the ATO supported Ir-based electrocatalyst’s activity for oxygen evolution reaction (OER) in acidic media. Ability of the ATO supports to anchor the Ir nanoparticles, measured as the fraction of Ir species from reaction bath landed on ATO support (conversion efficiency; η c ), is found to be strongly dependent on its surface chemistry, characterized in terms of presence of surface oxygen groups (O surface ). Both O surface content and electronic conductivity of ATOs show strong influence on OER activity. In general, high conductivity and low O surface though low O surface may compromise η c content are preferred for high OER activity, . The optimal catalyst demonstrates superior OER activity of 777 A g 1 , 2.5 times that of the state-of-the-art commercial catalyst at 1.65 V vs. RHE. Further, the synthesized catalysts exhibit durability comparable to that of the commercial counterpart.
