Construct validity of functional capacity tests in healthy workers

Background: Functional Capacity (FC) is a multidimensional construct within the activity domain of the International Classification of Functioning, Disability and Health framework (ICF). Functional capacity evaluations (FCEs) are assessments of work-related FC. The extent to which these work-related FC tests are associated to bio-, psycho-, or social factors is unknown. The aims of this study were to test relationships between FC tests and other ICF factors in a sample of healthy workers, and to determine the amount of statistical variance in FC tests that can be explained by these factors. Methods: A cross sectional study. The sample was comprised of 403 healthy workers who completed material handling FC tests (lifting low, overhead lifting, and carrying) and static work FC tests (overhead working and standing forward bend). The explainable variables were; six muscle strength tests; aerobic capacity test; and questionnaires regarding personal factors (age, gender, body height, body weight, and education), psychological factors (mental health, vitality, and general health perceptions), and social factors (perception of work, physical workloads, sport-, leisure time-, and work-index). A priori construct validity hypotheses were formulated and analyzed by means of correlation coefficients and regression analyses. Results: Moderate correlations were detected between material handling FC tests and muscle strength, gender, body weight, and body height. As for static work FC tests; overhead working correlated fair with aerobic capacity and handgrip strength, and low with the sport-index and perception of work. For standing forward bend FC test, all hypotheses were rejected. The regression model revealed that 61% to 62% of material handling FC tests were explained by physical factors. Five to 15% of static work FC tests were explained by physical and social factors. Conclusions: The current study revealed that, in a sample of healthy workers, material handling FC tests were related to physical factors but not to the psychosocial factors measured in this study. The construct of static work FC tests remained largely unexplained.

Raising the organizational capacity of voluntary sport clubs

Aim of this study is to understand which approach (expert or process orientated) sport club consultants use in succesfully raising the organizational capacity of voluntary sport clubs in the northern part of the Netherlands. Around 130 professional sport club consultants are active in the northern part of the Netherlands, but it is not clear which approach they use in raising the organizational capacity of the clubs within a specific context and if this approach is effective. Theoretical backgroundA sport club with great organizational capacity has the ability to offer their sport, now and in the future, in a sustainable and socially responsible way to (potential) members. Dutch voluntary sport clubs (VSCs) are facing several challenges in perceived consumerist behavior by members (Van der Roest, 2015), demands by the government to attribute to the social policy agenda (Coalter, 2007) and declining number of members in complex contexts (Wollebæk, 2009). Between 300-500 sport club consultants, mostly funded by local governments or sport associations, are tasked to raise the organizational capacity of these VSCs in the Netherlands. Most consultants play an expert role delivering generic interventions on specific topics as recruiting volunteers, sponsorships or positive behavior support. The other consultants play a process consultation role in which a holistic strategic change approach is used for more sustainable organizational development (Schein, 1999). The context of the organizations (VSC’s) is determining which approach is the best in developing the organizational capacity. But most of the time consultants use the same, mostly expert role, in consulting the organizations (Boonstra & Elving, 2009). Therefore it is not clear which approach (expert or process orientated) sport club consultants in the Netherlands use in raising the organizational capacity of VSC’s in different contexts. Methodology, research design, and data analysisThe study will be conducted from March 2017 till the end of July 2017 in the northern part of the Netherlands. In March we have started with identifying successful sport club consultants in three steps: these steps show a qualitative description of the current competences, approaches and interventions (repertoire) as seen by the sport club consultants in our target group:1) A group of experts have been gathered to formulate criteria for the competences, approaches and interventions of a successful process orientated sport club consultant. 2) The criteria from step 1 are validated by theory about organizational development and consulting of organizations. Thereafter the criteria are processed into a digital survey 3) The survey has been send to n=130 sport club consultants in the northern part of the Netherlands. 4) Based on the output of the survey, profiles will be developed of different types sport club consultants (process orientated, mediator, supporter, coach, expert) and the approaches per type of consultant. For each profile a ranking will be made based on which criteria (from step 1) the consultants meet. This ranking will be used to make a selection of successful sport club consultants to conduct research in five multiple case studies. From June on multiple case studies will be conducted in which five process consultants are working with a VSC. A case study protocol will be developed that observe the consultant in three sessions at the club. In addition interviews will be conducted with the consultant, the board of the club, and other relevant stakeholders. With a cross-case synthesis patterns will be developed in the way the consultants worked and how these approaches were interpreted and valued by the various stakeholders. Results, discussion, and implications/conclusionsIn the expected results both approaches and interventions (repertoire) of the consultant as their competences and qualities are analyzed which will result in the profiling of the active sport club consultants. We also gain insights in which approach of the sport club consultants is the most effective in raising the organizational capacity of a VSC in a given context. New insights on how consultants can successfully contribute to the sustainable organizational development of VSCs will be presented.

Extended Definition of Capacity in Airport Systems

Nowadays the main airports throughout the world are suffering because their capacity are getting close to saturation due to the air traffic which is still increasing besides the economic crisis and oil prices. In addition, the forecasts predict an increase in air traffic of at least 3.6% until 2020. This situation makes very important to come up with solutions to alleviate capacity congestions in the main airports throughout the world. Capacity has been perceived traditionally as the factor to be addressed in airport systems and it is faced through a technical perspective. In this paper we propose to change the mind-set and view capacity of airport systems taking other factors than pure technical ones. The discussion is illustrated with the example of Schiphol Airport.

The conceptualisation of vital communities related to ageing in place

Older people today are more likely to age in their own private living environment. However, many face declining health and/or other issues that affect their ability to live independently and necessitate additional support. Such support can be provided by formal networks, but a considerable part can also be offered by informal networks of older people themselves. Going beyond these networks, older people can additionally and perhaps even more substantially benefit from vital communities. Nevertheless, even though this term is increasingly common in the literature, its meaning remains indistinct. A more thorough understanding of this concept might provide valuable knowledge that health care professionals, researchers and community workers can use to offer meaningful and effective support. The purpose of this paper is to draw on existing empirical research on vital communities to build knowledge of the different descriptions and dimensions of the concept. Arksey and O’Malley’s scoping review methodology was adopted. Our search, conducted on 23 March 2020 and updated on 06 January 2021, yielded 4433 articles, of which six articles were included in the scoping review. We deduced that the conceptualisation of a vital community is based on three dimensions: the aim of a vital community, the processes behind a vital community and the typical characteristics of a vital community. None of the selected studies have mapped all three dimensions. Nevertheless, we assume that understanding all three matters when vital communities aim to contribute to the quality of life of people ageing in place.
