Cognitive fatigue is a psychological state characterised by feelings of tiredness and impaired cognitive functioning arising from high demands. This paper examines the recent research progress on assessment provides informed recommendations for future research. Traditionally, introspectively assessed through self-report or objectively inferred decline in behavioural performance. However, more recently, researchers have attempted to explore biological underpinnings understand measure this phenomenon. In particular, there evidence indicating that imbalance between sympathetic parasympathetic nervous activity appears be physiological correlate fatigue. has been indexed various heart rate variability indices also proposed as putative biomarkers Moreover, contrast traditional inferential methods, growing interest using data-driven approaches assessing The ubiquity wearables with capability collect large amounts data major facilitator growth area. Preliminary findings indicate such datasets can used accurately predict machine learning approaches. Overall, potential combining domain-specific knowledge gained biomarker should further explored build robust predictive models

Reducing Healthcare Employees’ Burnout through Ethical Leadership: The Role of Altruism and Motivation

International Journal of Environmental Research and Public Health, Journal Year: 2022, Volume and Issue: 19(20), P. 13102 - 13102

Globally, employee burnout (EBO) is a black swan in healthcare management. Previous organizational management literature shows that EBO was often misunderstood by assuming it as personal issue. However, the new definition World Health Organization (WHO) clearly indicates an occupational phenomenon places responsibility on organizations to manage it. Although recent evidence suggests ethical leadership (ELP) style may be important mitigate EBO, shockingly, such relationships were not tested systems, especially low- and middle-income countries. Filling this knowledge gap existing body of knowledge, study aimed investigate ELP–EBO relationship. To explain underlying mechanism how ELP reduces included two psychological factors mediator moderator: altruism (AL) intrinsic motivation (IM). The data obtained from hospital employees via self-administered questionnaire (n = 289, paper-pencil method). A hypothetical framework designed for empirical validation through structural equation modeling (SEM). Empirical confirmed risk among employees, AL mediates results also conditional indirect role IM above proposed mediated This study’s outcomes can help administration deal with EBO’s epidemic framework. Other, different implications have been discussed detail.

In order conduct this applied study, a random sample (N = 813) was chosen. Male and female employees in Jazan region Saudi Arabia were surveyed collect data that analyzed using descriptive statistics structural equation modeling (path analysis). instrument structured questionnaire, validity which evaluated by expert panel for facial content-based validity. addition, Cronbach’s alpha coefficients (0.743–0.929) utilized confirm instrument’s reliability. To three proposed hypotheses, path analysis applied. Favorable statistically significant (p < 0.05) results suggested direct is positive. empowerment considerably favorably mediated relationship between responsibility. research indirect effects revealed has substantial Finally, it should be noted both impacts are considerable model’s fitness indices satisfactory.
