Healthcare centers are ideal settings to identify and motivate parents to adhere to healthier lifestyles in order to reverse their child's excessive weight. However, such promotions are time- and resource-consuming, and primary health care needs new approaches to engage parents. In this article, we present an app for that purpose, with tailored recommendations for parents regarding young children's lifestyles (eating, drinking, moving, and sleeping habits) with gamification mechanics for parents, and a serious game for their children, aged 3-6 years. Healthcare center based questionnaires were used to assess parent's acceptance of the app. We also determined their enrollment and retention rates with a pilot study, in order to test the implementation of a randomized controlled trial (RCT) in the future (pilot trial registration: ClinicalTrials.gov NCT03881280). In the pilot study, we tested their engagement with the app during a four-week period through a monitoring website. In the acceptance test (n = 13), parents rated the app a median score of seven on a ten-point scale. In the pilot study (n = 21), all parents in the intervention group used the app. The retention rate was 71.4%. This study indicated some areas of improvement related to gaming mechanics in order to increase participation. Healthcare center's professionals and parents of children with overweight/obesity accepted this innovative approach. In addition, it is feasible to test its impact on children's lifestyle by conducting an RCT in the future.

Abstract
Senior entrepreneurship is getting increasing prominence in research, academia, and business. Given the demographic shifts occurring in Western Europe, it is also becoming a nuclear topic of interest for policymakers. Still, existing literature overlooked the emergent trend encompassing older individuals which, with different leitmotifs, starting-up new enterprises after decades as employees. In doing so, they convey formal and informal knowledge, networks, experience, savoir faire, and financial endowments, nurtured along the years, which is an evident advantage compared to the younger counterparts. Due to the raising number of negative experiences in the job market, either in getting or maintaining a position, senior workers look up for alternatives. Sometimes being pushed by necessity, other times pulled by opportunity identification and independence, seniors are increasingly making their best to overcome unsatisfying or insufficient conditions as employees. Enhancing entrepreneurial initiative across older individuals is urgent for policy makers due to the need to find occupation for an aging population and their contribution to income generation, at the same time, social and human capital will be leveraged, multiplying the effects of other policy actions such as education. Using the GEM database, this article aims to offer an overview on the role of age in entrepreneurial intention and its nature, addressing the nonlinearities of the effect. This new methodological framework can be used as a basis for future empirical research on the topic of senior entrepreneurship; additionally, it aims contributing to a better understanding of the role of age in shifting the individual reasons for starting a business, controlling for other individual characteristics. The identification of the particular features of the different age cohorts along with gender, education, social context or macro-economic contexts will shed some light on the specific policy packages needed to reinforce the entrepreneurial initiative as a vehicle to promote sustainable and inclusive growth along the European Countries.

Abstract
Frequently carrying high loads and performing repetitive tasks compromises the ergonomics of individuals, a recurrent scenario in hospital environments. In this paper, we design a logistic planner of a fleet of autonomous mobile robots for the automation of transporting trolleys around the hospital, which is independent of the space configuration, and robust to loss of network and deadlocks. Our robotic solution has an innovative gripping system capable of grasping and pulling non-modified standard trolleys just by coupling a plate. Robots are able to navigate autonomously, to avoid obstacles assuring the safety of operators, to identify and dock a trolley, to access charging stations and elevators, and to communicate with the latter. An interface was built allowing users to command the robots through a web server. It is shown how the proposed methodology behaves in experiments conducted at the Faculty of Engineering of the University of Porto and Braga's Hospital.
