Time Dynamics of the Dutch Municipality Network
Based on data sets provided by Statistics Netherlands and the International
Institute of Social History, we investigate the Dutch municipality merging
process and the survivability of municipalities over the period 1830-2019. We
examine the dynamics of the population and area per municipality and how their
distributions evolved during the researched period. We apply a Network Science
approach, where each node represents a municipality and the links represent the
geographical interconnections between adjacent municipalities via roads,
railways, bridges or tunnels which were available in each specific yearly
network instance. Over the researched period, we find that the distributions of
the logarithm of both the population and area size closely follow a normal and
a logistic distribution respectively. The tails of the population distributions
follow a power-law distribution, a phenomenon observed in community structures
of many real-world networks. The dynamics of the area distribution are mainly
determined by the merging process, while the population distribution is also
driven by the natural population growth and migration across the municipality
network. Finally, we propose a model of the Dutch Municipality Network that
captures population increase, population migration between municipalities and
the process of municipality merging. Our model allows for predictions of the
population and area distributions over time.Comment: 48 pages, 26 figure
Diagnosing Sport-Related Flow Limitations in the Iliac Arteries Using Near-Infrared Spectroscopy
Background: A flow limitation in the iliac arteries (FLIA) in endurance athletes is notoriously difficult to diagnose with the currently available diagnostic tools. At present, a commonly used diagnostic measure is a decrease in ankle brachial index with flex hips (ABIFlexed) following a maximal effort exercise test. Near-infrared spectroscopy (NIRS) is a non-invasive technique that measures skeletal muscle oxygenation as reflected by the balance of O2 delivery from microvascular blood flow and O2 uptake by metabolic activity. Therefore, NIRS potentially serves as a novel technique for diagnosing FLIA. The purpose of this study is to compare the diagnostic accuracy of NIRS-derived absolute, amplitude, and kinetic variables in legs during and after a maximal exercise test with ABIFlexed. Methods: ABIFlexed and NIRS were studied in 33 healthy subjects and 201 patients with FLIA diagnosed with echo-Doppler. Results: After maximal exercise, NIRS kinetic variables, such as the half value time and mean response time, resulted in a range of 0.921 to 0.939 AUC for the diagnosis of FLIA when combined with ABIFlexed. Conversely, ABIFlexed measurements alone conferred significantly worse test characteristics (AUC 0.717, p < 0.001). Conclusions: NIRS may serve as a diagnostic adjunct in patients with possible FLIA.</p
Accelerating CGIARâS digital transformation: A high-level assessment of digital strategy across CGIAR
Estimating VO<sub>2peak</sub> in 18â90 Year-Old Adults:Development and Validation of the FitMĂĄx©-Questionnaire
Purpose: Cardiorespiratory fitness (CRF) plays an essential role in health outcomes and quality of life. However, it is often not assessed nor estimated. Objective CRF assessment is costly, labour intensive and not widely available. Patient-reported outcome measures estimate CRF more cost-efficiently, but current questionnaires lack accuracy. The aim of this study is to develop a new self-reported questionnaire to estimate CRF.</p
A global experiment on motivating social distancing during the COVID-19 pandemic
Finding communication strategies that effectively motivate social distancing continues to be a global public health priority during the COVID-19 pandemic. This cross-country, preregistered experiment (n = 25,718 from 89 countries) tested hypotheses concerning generalizable positive and negative outcomes of social distancing messages that promoted personal agency and reflective choices (i.e., an autonomy-supportive message) or were restrictive and shaming (i.e., a controlling message) compared with no message at all. Results partially supported experimental hypotheses in that the controlling message increased controlled motivation (a poorly internalized form of motivation relying on shame, guilt, and fear of social consequences) relative to no message. On the other hand, the autonomy-supportive message lowered feelings of defiance compared with the controlling message, but the controlling message did not differ from receiving no message at all. Unexpectedly, messages did not influence autonomous motivation (a highly internalized form of motivation relying on oneâs core values) or behavioral intentions. Results supported hypothesized associations between peopleâs existing autonomous and controlled motivations and self-reported behavioral intentions to engage in social distancing. Controlled motivation was associated with more defiance and less long-term behavioral intention to engage in social distancing, whereas autonomous motivation was associated with less defiance and more short- and long-term intentions to social distance. Overall, this work highlights the potential harm of using shaming and pressuring language in public health communication, with implications for the current and future global health challenges
