- Containerizing and evaluating the WRF model for cloud-based HPCPublication . Gouveia, Diogo Manuel Sales; Baras, Karolina; Vieira, Rui Ricardo AlmeidaNumerical models are mathematical representations that solve algebraic or differential equations to simulate phenomena across time and space. Some models, such as the Weather Research and Forecasting (WRF) model, are applied to weather prediction, providing valuable information to individuals, companies, institutions, and governments on potential future events. However, the WRF model can become highly computationally demanding, requiring increasingly power ful hardware resources with the increase of the resolutions and complexity of the simulations. High-Performance Computing (HPC) allows users to leverage powerful instances tailored to their needs, providing the necessary hardware resources for running complex WRF simulations. Mean while, cloud computing presents an enticing option for computationally demanding programs, offering advantages such as economies of scale, high reliability, and availability. On the software side, compiling, configuring, and installing multiple libraries are essential to exploit WRF’s po tential, which can be an arduous task. This study explores a cloud-enabled approach using pre configured Docker images and compares it to on-premises, HPC, and cloud solutions. We also analyze whether cloud computing is economically and performance-wise viable, using a compa rable base architecture across multiple cloud providers, and assess if the convenience of Docker meets the requirements despite potential overhead.
- Parents and athletes’ perceptions of parental involvement practices in youth basketballPublication . Lopes, Maria V.; Ihle, Andreas; Gouveia, Élvio Rúbio; Marques, Adilson; Cinarli, Fahri Safa; França, Cíntia; Ihle, Andreas; Gouveia, Élvio Rúbio; Marques, Adilson; França, CíntiaParental involvement in youth sports is an increasingly relevant topic because of its key implications for children’s development in youth sports. This study’s aims are threefold: (1) to investigate parental involvement practices based on parents’ previous sports experiences, (2) to examine athletes’ and parents’ perceptions on parental involvement practices across different age categories, and (3) to compare the athletes’ and parents’ overall perceptions on parental involvement practices. In total, 423 participants (151 youth players and 272 parents) completed the Parental Behaviors in Sports (PBSP) questionnaire. The PBSP includes separate versions for parents and athletes, each assessing five key dimensions: (1) sports support, (2) competition attendance, (3) technical influence, (4) performance pressure, and (5) sports expectations. In the parents’ group, 154 participants (56.6%) reported previous sports experience. No statistically significant differences were observed in the PBSP dimensions between parents with and without previous sports experience. Parents’ years of sports experience negatively correlated with performance pressure (r = −0.155, p = 0.013) and expectations (r = −0.149, p = 0.017). Age group analysis showed lower competition attendance in the U18 group and higher expectations in the U12 group. When comparing parents’ and athletes’ responses, statistically significant differences emerged in all PBSP dimensions except for performance pressure. These findings underscore the importance of aligning parental involvement with children’s experiences to foster enjoyment, reduce pressure, and support sustained engagement in youth sports.
