Leadership and Management Strategies That Promote the Implementation of Consumer-Centred Care in Residential Aged Care Facility

引用

Journal of Biosciences and Medicines 2019年第6期7卷 73-101页

作者： mohanaa naidu Griffith University Queensland Australia

Enhancing leadership and management in the aged care sector is likely to be achieved through adopting cultural changes that are aimed at promoting a healthy working environment in which employees have job satisfaction and are motivated to commit their efforts towards achieving the organizational goals. A conducive working environment offers support, inspiration, and harmonious social relationships among the workers in the aged care homes. Both management and leadership play a role in enhancing a healthy working condition obligatory for implementing new care initiatives, effective strategies and practices that should be appropriately articulated. The current research study aims at examining effective strategies and practices that enhance management and leadership in the aged care sector with the aim of ensuring that all care initiatives are successfully implemented. The research question for the study is focused on the leadership and management strategies used to promote the implementation of consumer-centered care in residential aged care facility. Analysis was aimed at understanding the importance of management and leadership in promoting the implementation of various initiatives surrounding new care models;in this case, the consumer-centered care model in the aged care facilities across Australia and other parts of the world. One major theme emerged from the analysis, which was transforming the organizational culture that was promoted through changing the organizational systems, embracing the “yes culture”, and changing the individuals’ work habits. The “yes culture” means that all individuals are dedicated to succeeding in making excellent decisions autonomously. The study identified that managers and leaders shifted their emphasis from compliance with laws and regulations to create a conducive work environment that empowers workers to support any new initiatives undertaken. The strategy was successful, according to the findings.

Crosstalk between degradation and bioenergetics: how autophagy and endolysosomal processes regulate energy production

引用

Neural Regeneration Research 2025年第3期20卷 671-681页

作者： Angelid Pabon Jagannatham naidu Bhupana Ching-On Wong Department of Biological Sciences Rutgers UniversityNewarkNJUSA

Cells undergo metabolic reprogramming to adapt to changes in nutrient availability, cellular activity, and transitions in cell states. The balance between glycolysis and mitochondrial respiration is crucial for energy production, and metabolic reprogramming stipulates a shift in such balance to optimize both bioenergetic efficiency and anabolic requirements. Failure in switching bioenergetic dependence can lead to maladaptation and pathogenesis. While cellular degradation is known to recycle precursor molecules for anabolism, its potential role in regulating energy production remains less explored. The bioenergetic switch between glycolysis and mitochondrial respiration involves transcription factors and organelle homeostasis, which are both regulated by the cellular degradation pathways. A growing body of studies has demonstrated that both stem cells and differentiated cells exhibit bioenergetic switch upon perturbations of autophagic activity or endolysosomal processes. Here, we highlighted the current understanding of the interplay between degradation processes, specifically autophagy and endolysosomes, transcription factors, endolysosomal signaling, and mitochondrial homeostasis in shaping cellular bioenergetics. This review aims to summarize the relationship between degradation processes and bioenergetics, providing a foundation for future research to unveil deeper mechanistic insights into bioenergetic regulation.
