Abstract

This study evaluates the influences of organizational commitment components on job satisfaction and job performance among Islamic boarding school (IBS) teachers. It also aimed to decide the mediating effect of job satisfaction on the relationship between organizational commitment and job performance. This comparative study compares the path coefficient between exogenous and endogenous constructs based on respondents’ countries, Malaysia and Indonesia. Through a simple random sampling, the data were gathered from 247 respondents. The analysis was conducted through partial least square structural equation modeling (PLS-SEM) approaches (measurement model, structural model, and multi-group analysis). The measurement model informed that the obtained data was valid and reliable. The structural model examination reports that normative and continuance commitment strongly predict job satisfaction. Similarly, continuance commitment and job satisfaction are significant predictors of job performance. As a mediator, job satisfaction successfully mediates the relationships between continuance commitment and job performance and between normative commitment and job performance. No significant differences emerge from the multi-group analysis results between IBS teachers from Kedah (Malaysia) and Jambi (Indonesia), regarding all direct paths between the constructs. This article provides knowledge contributions from Indonesia and Malaysia, in the context of Islamic education.

Abstract

BACKGROUND: Numerous inflammatory diseases are linked to increased endothelial permeability through the nitric oxide (NO) flux in endothelial cells. Luteolin has in vitro and in vivo anti-inflammatory properties and has been reported to reduce endothelial permeability. However, the exact mechanism/s are yet to be determined. Thus, the present study was conducted to investigate the effects of luteolin in reducing endothelial permeability in vitro using bradykinin (BK) or sodium nitroprusside (SNP) through the NO pathway and the NO radical scavenging property of luteolin.METHODS: Human umbilical vein endothelial cells (HUVECs) in the treatment groups were dosed with luteolin at 5, 10, and 25 µM concentrations and allowed to incubate for one hour prior to induction. The L-NAME or HOE 140 were administered prior to the induction of BK or SNP in HUVECs. The NO radical scavenging test, the nitrite determination assay using L-NAME as antagonist, and the in vitro vascular permeability testing using HOE 140 as antagonist were performed.RESULTS: Endothelial permeability was decreased dose-dependently by 5, 10, and 25 µM luteolin in vitro via lowering NO generation. In comparison to HOE 140, luteolin suppressed the enhanced endothelial permeability more effectively. The suppression was 98.02% by 25 µM luteolin compared to HOE 140 94.05%. It was also discovered that luteolin, when incubated with SNP in a dose-dependent manner, possessed potent NO radical scavenging activities.CONCLUSION: The current data demonstrated luteolin's ability to scavenge NO radicals and significantly decrease endothelial permeability through the NO route. Thus, in complementary medicine, luteolin might be potential to improve endothelial permeability suppressor in reducing inflammation.KEYWORDS: luteolin, endothelial permeability, NO, scavenging property, HUVECs

Abstract

Background: Sport and Exercise Psychology (SEP) has evolved significantly as a scientific discipline, yet comprehensive mapping of its intellectual structure, thematic evolution, and research trends remains limited, particularly for the period encompassing recent methodological and conceptual advances. Aims: This study mapped the bibliometric landscape of SEP research indexed in Scopus (2005–May 2025) and synthesised high-quality empirical evidence to address six research questions, identifying knowledge gaps and future directions. Methods: A dual-method approach combined bibliometric analysis of 2,637 Scopus-indexed articles using VOSviewer software with a PRISMA-guided systematic literature review. The search strategy employed the query TITLE (“Sport and Exercise Psychology”) in the Scopus database, limited to English-language original research articles published between 2005 and May 2025. Bibliometric indicators included publication trends, citation patterns, author productivity (Lotka's Law), journal distribution (Bradford's Law), geographical contributions, and keyword co-occurrence networks. Thirty high-quality empirical studies were reviewed to address six research questions spanning motivation, identity, professional practice, mental health interventions, methodology, and psychological risks. Results: Annual publication growth averaged 13.43%, peaking at 293 articles in 2024. The United States, United Kingdom, and Australia dominated output (32% combined). “Physical activity,” “exercise,” and “mental health” emerged as dominant themes, reflecting expansion beyond performance psychology toward holistic wellbeing. Conceptual structure analysis revealed four primary dimensions: sport motivation and performance, exercise and mental health, youth sport and education, and cognitive aspects. The systematic review identified three cross-cutting themes: progressive methodological pluralism, tension between globalising professional standards and culturally responsive practice, and convergence of researcher epistemology with practitioner identity formation. Conclusion: SEP demonstrates robust growth and increasing methodological sophistication, yet geographical disparities, underrepresented populations, and research-practice gaps require strategic attention to enhance global applicability and the implementation of evidence-based practice. This study contributes to the field by presenting the first integrated bibliometric-systematic review of SEP over two decades, offering a two-method framework that combines structural mapping of knowledge production with a substantial synthesis of empirical evidence, and an approach that has been underutilized in previous SEP reviews.
