To evaluate the 5-year course of physical work capacity of participants with early symptomatic osteoarthritis (OA) of the hip and/or the knee; to identify trajectories and explore the relationship between trajectories and covariates. Methods In a prospective cohort study, physical work capacity was measured at baseline, using a test protocol (functional capacity evaluation) consisting of work-related physical activities. Participants were invited to participate in 1, 2 and 5 year follow-up measurements. Multilevel analysis and latent classes analysis were performed, in models with test performances as dependent variables and age, sex, work status, self-reported function (Western Ontario McMasters Arthritis Scale-WOMAC), body mass index (BMI) and time as independent variables. Multiple imputation was used to control for the influence of missing data. Results At baseline and after 1, 2 and 5 years there were 96, 64, 61 and 35 participants. Mean (SD) age at baseline was 56 (4.9) years, 84% were females. There was no statistically significant change in test performances (lifting low and high, carrying, static overhead work, repetitive bending, repetitive rotations) between the 4 measurements. Male sex, younger age and better self-reported function were statistically significant (p < 0.05) determinants of higher performance on most of the tests; having a paid job, BMI and progression of time were not. Three trajectories were identified: 'weak giving way', 'stable and able', and 'strong with decline'. Discussion In subgroups of participants with early symptomatic OA, determined by age, sex and self-reported function, physical work capacity seems to be a stable characteristic over 5 years.
KLM is downsizing the full-freight cargo fleet in Schiphol Airport, for that reason it is important for the company and the airport to explore the consequences of moving the cargo transported by the full freighters into the bellies of the passenger flights. The consequences of this action in terms of capacity and requirements are still unknown. The current study illustrates how to analyse the uncertainty present in the system for identifying the limitations and potential consequences of the reduction of full freighter fleet. The options we identify for coping with the current demand is by adjusting their load factors or increase the number of flights. The current model includes the airside operation of the airport, the truck movements and the traffic that arrives at Schiphol which allows addressing the impact of uncertainties of the operation as well as the limitations and potential problems of the phasing-out action.
Tourism has been a growing industry in Europe in the last decades till 2020. Numerous cities were suffering from too many visitors what resulted in problems regarding support (of inhabitants) and carrying capacity of the destination. Then COVID-19 changed the world and tourism collapsed. Now, two years after the pandemic, cities and regions need to develop new strategies to rebuild tourism. Cities where there is overtourism are facing an extra challenge: to find a good balance between visitors, communities and environment. Six cities and regions (Amsterdam (NL), Krakow (PL), Tallinn (EST), Andalucía/Sevilla (ES), Rome (IT) and Brasov (RO)) that (regularly) experience over-tourism have joined forces how to develop new policy strategies to better distribute tourism in time and space. The objective of the project is to improve the performance of the local-regional strategies and policies by strengthening their contribution to find balance in tourism with a focus on spreading tourism over a wider area, making use of the opportunities offered by the city and region. The project aims to strengthen the positive effects of tourism and to reduce the negative effects of tourism.
