- Disentangling the effects of ego and task-involving climate perceptions on cohesion in youth sportPublication . Chicau Borrego, Carla; Monteiro, Diogo; Benson, Alex J.; Miguel, Mauro; Teixeira, Eduardo; Silva, CarlosThe present study evaluated how the combination of ego- and task-involving climate perceptions related to youth soccer athletes’ perceptions of team cohesion. We hypothesized that athletes would perceive their group to be less cohesive as ego climate perceptions increased in salience relative to task climate perceptions. In addition, the factor structure and longitudinal measurement invariance of Youth Sport Environment Questionnaire (YSEQ)—Portuguese version was also analyzed. A total of 956 national level youth male soccer athletes’ belonging to 49 different teams participated in the study. Using a prospective design with two time points, the polynomial regression with a response surface analysis indicated that the effect of an ego-involving climate on task cohesion varied as a function of task-involving climate perceptions. Specifically, athletes reported lower levels of task cohesion as ego-involving climate perceptions began to predominate over task-involving climate perceptions. Furthermore, a strong taskinvolving climate buffered against the negative effects of ego-involving climate perceptions on task cohesion. Regarding social cohesion, we only observed a positive linear association between task-involving climate perceptions and social cohesion. Our findings support the validity and reliability of two factors underlying the YSEQ and its longitudinal invariance across time in an elite youth sample. Future studies should strive to replicate these results in other sports and with female athletes. Our results provide insight into how task-involving and ego-involving climate perceptions combine to shape how elite youth athletes view their group environment.
- Energy consumption behaviour characterization with mobile gamificationPublication . Toasa, Renato; Silva, Carlos; Silva, Catarina; Gonçalves, Dulce; Neves, Luis; Marcelino, LuisExcessive electric energy consumption results in high costs for consumers, and often on using non-renewable resources. Additionally, in many cases, it is difficult for the consumer or for the energy provider to determine if one or more equipment is being used efficiently. Therefore, the main objective of this work is to promote awareness about energy consumption. For that purpose, a mobile application with a gamification approach was designed to identify users’ behaviors towards the use of energy and, based on the user’s answers, offer advices to save energy and promote ecological awareness. The outcome of using gamification on a mobile application with such goals results in a streamlined data collection application that combines information and entertainment. The collected information is being gathered to potentially create consumer profiles that better reflect the user’s energy consumption.
- JavaScript Middleware for Mobile Agents Support on Desktop and Mobile PlatformsPublication . Silva, Carlos; Costa, Nuno; Grilo, Carlos; Veloz, JorgeThe evolution of technology in interconnection solutions such as Networks or the Internet, have allowed many communication architectures to be born and a varied interconnectivity. Here, we present a project that relies on the mobile agent computing paradigm. A middleware using the JavaScript language that allows the execution and ability to move mobile agents through the local network and Internet. This initiative arose as a way of dealing with problems raised by the considerable amount of existing Java based mobile agents middleware, which force the installation of the Java Virtual Machine in the devices, making complicated its execution in operating systems like macOS, iOS and others non-java friendly O.S. Our middleware works steadily in all operating systems, requiring only the installation of node.js. For mobile platforms the middleware is developed using React-native that allows it to run on mobile operating systems such as Android and iOS.
- Perspetivas uma forma de expressão : o audiovisual como estratégia de inovação socialPublication . Freire, Carla; Silva, CarlosEngaging community in several projects, regardless the particular features that each member can have it is important to promote leisure, well-being and life quality in citizen lives. Therefore it is important to foster strategies that allow everyone, without any kind of discrimination, to participate in different activities. This paper aims to disclosure Perspetivas Project that emerge with the objective of promoting innovative interventions that allow social inclusion of people with intellectual disability, increasing their capacity to create audiovisual works. Perspetivas consist in training activities of audiovisual language to people with intellectual disability, in order to allow them create audiovisual products. Besides promoting leisure experiences, Perspetivas also has the potential to the acquisition and/or development of different skills, such as capacity of self-expression and communication. The project implementation was powerful and enriching, given the collaborative work that has benefited all the involved persons, contributing to promote a new strategy of social innovation.
- Perspetivas: utilização de audiovisuais por pessoas com necessidades especiais: avaliação de uma intervenção do ponto de vista dos cuidadoresPublication . Freire, Carla; Silva, CarlosA qualidade de vida das pessoas passa pela participação e envolvimento em diferentes atividades que promovam a autonomia e desenvolvimento de diferentes competências. O Projeto Perspetivas surge pela necessidade de criação de intervenções com públicos diversificados, que permitam promover o desenvolvimento de competências, através de atividades e ações relacionadas com a linguagem e produção audiovisual. Foi realizada uma intervenção numa Instituição Particular de Solidariedade Social para pessoas com deficiência intelectual, onde os clientes criaram três filmes. O estudo apresentado pretende avaliar a intervenção, do ponto de vista dos cuidadores. Desta forma, foi-lhes aplicado um inquérito por questionário, com os objetivos de: explorar de que forma veem esta intervenção na vida dos clientes; analisar em que medida a intervenção contribui para o desenvolvimento de competências; e identificar os aspetos positivos e menos positivos da intervenção. Os resultados revelam que o Projeto Perspetivas teve sucesso, sendo um projeto inovador e diferente do quotidiano, no qual foi possível dar palavra à instituição, rentabilizando as suas áreas fortes e desenvolvendo diferentes capacidades nos clientes. Não foram identificados aspetos menos positivos, tendo todos os cuidadores envolvidos manifestado interesse em voltar a participar numa nova edição do projeto, caso voltasse a concretizar-se.
