Twirre is a new architecture for mini-UAV platforms designed for autonomous flight in both GPS-enabled and GPS-deprived applications. The architecture consists of low-cost hardware and software components. High-level control software enables autonomous operation. Exchanging or upgrading hardware components is straightforward and the architecture is an excellent starting point for building low-cost autonomous mini-UAVs for a variety of applications. Experiments with an implementation of the architecture are in development, and preliminary results demonstrate accurate indoor navigation

PurposeTo support the development and implementation of exercise programming for people with prostate cancer (PC), we investigated their views on exercise.MethodsOnline survey with open recruitment. We collected data on clinical and sociodemographic variables, experiences with exercise advice, outcome expectations, and preferences. We explored determinants of (1) having been counselled about exercise and (2) preferring supervised exercise.ResultsThe survey was completed by 171 patients (mean age = 70 years, SD = 6.5) from all PC treatment pathways. Sixty-three percent of the respondents reported never having been informed about the potential benefits of exercise. Forty-nine percent preferred exercise to be supervised. Respondents generally reported a positive attitude towards exercise. Seventy-four percent indicated barriers to exercising, including fatigue and lack of access to specific programmes. Outcome expectations were generally positive but moderately strong. Receiving hormonal therapy and younger age were significantly associated with having received exercise advice. Being insured and having higher fatigue levels contributed significantly to the preference for supervised exercise.ConclusionDutch people with PC report receiving insufficient effective exercise counselling. Yet, they are open to exercise and expect exercise to improve their health, although they experience various barriers that limit their ability to exercise.Implications for Cancer SurvivorsThe moderate outcome expectations for exercise of people with PC and their limited recall of exercise counselling highlight the need for better integration of exercise in clinical pathways. The lack of access to specific programming limits the use of evidence-based exercise programmes for people with PC.

Participation in sport can positively impact young lives by promoting social development and also physical and mental health and well-being. However, several challenges related to sport participation still exist, such as dropout, health risks related to overtraining, and misconceptions about what evidence-based sport coaching knowledge is. The present chapter critically discusses the scientific and cultural premises on which current coach education in sport is based and offers reflections on how this education can be developed and improved. We suggest that current sports science models, characterised by separate siloes of knowledge, may limit holistic approaches to sports coaching. Additionally, these systems of knowledge are created by power dynamics that are explicitly and implicitly valued in coach education, leading to the production of normative ideas about sports coaching and athlete development. This limited view may lead to blind spots in coach expertise development and hinder the improvement of coaching and coach education. We conclude by sharing some ideas that may contribute to the transformation of coach education through the design of more transdisciplinary approaches in coaching courses.
