The world population is ageing rapidly. As society ages, the incidence of physical limitations is dramatically increasing, which reduces the quality of life and increases healthcare expenditures. In western society, ~30% of the population over 55 years is confronted with moderate or severe physical limitations. These physical limitations increase the risk of falls, institutionalization, co-morbidity, and premature death. An important cause of physical limitations is the age-related loss of skeletal muscle mass, also referred to as sarcopenia. Emerging evidence, however, clearly shows that the decline in skeletal muscle mass is not the sole contributor to the decline in physical performance. For instance, the loss of muscle strength is also a strong contributor to reduced physical performance in the elderly. In addition, there is ample data to suggest that motor coordination, excitation-contraction coupling, skeletal integrity, and other factors related to the nervous, muscular, and skeletal systems are critically important for physical performance in the elderly. To better understand the loss of skeletal muscle performance with ageing, we aim to provide a broad overview on the underlying mechanisms associated with elderly skeletal muscle performance. We start with a system level discussion and continue with a discussion on the influence of lifestyle, biological, and psychosocial factors on elderly skeletal muscle performance. Developing a broad understanding of the many factors affecting elderly skeletal muscle performance has major implications for scientists, clinicians, and health professionals who are developing therapeutic interventions aiming to enhance muscle function and/or prevent mobility and physical limitations and, as such, support healthy ageing.
Purpose: Self-managed institutional homeless programmes started as an alternative to regular shelters. Using institutional theory as a lens, we aim to explore the experiences of stakeholders with the institutional aspects of a self-managed programs.Method: The data we analysed (56 interviews, both open and semi-structured) were generated in a longitudinal participatory case-study into JES, a self-managed homeless shelter. In our analysis we went back and forth between our empirical data and theory, using a combination of systematic coding and interpretation. Participants were involved in all stages of the research.Results: Our analysis revealed similarities between JES and regular shelters, stemming from institutional similarities. Participants shared space and facilities with sixteen people, which caused an ongoing discussion on (enforcement of) rules. Participants loathed lack of private space. However, participants experienced freedom of choice over both their own life and management of JES and structures were experienced more fluid than in regular care. Somestructures also appeared stimulated self-management.Conclusion: Our analysis showed how an institutional context influences self-management and suggested opportunities for introducing freedom and fluidity in institutional care.
Literature on the relationship between sustainability and human resource management (HRM) is just emerging. This chapter examines the role of the HRM function in advancing the sustainability agenda in the hotel industry. Drawing on 18 interviews with human resource managers (specialists), managers and employees drawn from 12 large and medium hotels in the Netherlands, this chapter reveals that HR professionals perform five different roles - of a coach, facilitator, architect, leader and custodian of sustainability conscience. These roles are based on Ulrich and Beatty’s (2001) model of HRM. It further shows that the propensity of human resource professionals to perform such roles is influenced by two major organisational contextual factors such as: a.) the sophistication of the HRM function and its relative position within the hotel’s decision-making structures; and b.) the stage of development of the hotel’s sustainability agenda. The chapter then concludes by highlighting implications for theory and practice.
