- Active Learning “Factory of Boxes” in the Teaching-Learning Processes in Engineering and EntrepreneurshipPublication . Silva, Ricardo; Garcez, Ana; Gomes, Maria; Morais, António; Lima, Tânia M.; Santos, Fernando Charrua; Franco, Mário"Factory of Boxes” is an Active Learning (AL) where concepts related to Industrial Engineering, Mechanics, Mechatronics, Electrotechnics and Entrepreneurial Management can be cultivated. The interconnection of these concepts offers the possibility of developing occupational related skills in the most diverse areas of knowledge. It is the use of AL, simulating the method of a factory which produces cardboard boxes in different layouts and production systems, namely: (a) Classic Taylorist-Fordist Model; (b) Positions’ Enrichment Volvo Model; (c) cell production Toyota Model; and (d) automated line Taylorist-Fordist Classic Model. Data collection was based on observation, counting and recording production in a simulated test at two Universities (UFPB – Brazil and UBI – Portugal) involving master students in Industrial Engineering. The data were analysed from the aspects of productivity and cycle-time. The results showed: (a) It is an economically viable AL since it uses low-cost materials (except for simulating with automated posts which requires some investment) and (b) the Classic Model has the highest cycle-time and the Toyota Model has higher productivity, although these results derive from simulations with a teaching-learning aim and cannot be generalized. With the involvement of students-apprentices, knowledge was absorbed through layout-sharing and analysis of work organisation models’ dynamics, involving activities using Engineering, Industrial Management and Entrepreneurship tools and concepts.
- Bilateral theta-burst magnetic stimulation influence on event-related brain potentialsPublication . Pinto, Nuno; Duarte, Marta; Gonçalves, Helena; Silva, Ricardo; Gama, Jorge; Patto, Maria Da Assunção VazTheta-burst stimulation (TBS) can be a non-invasive technique to modulate cognitive functions, with promising therapeutic potential, but with some contradictory results. Event related potentials are used as a marker of brain deterioration and can be used to evaluate TBS-related cognitive performance, but its use remains scant. This study aimed to study bilateral inhibitory and excitatory TBS effects upon neurocognitive performance of young healthy volunteers, using the auditory P300' results. Using a double-blind sham-controlled study, 51 healthy volunteers were randomly assigned to five different groups, two submitted to either excitatory (iTBS) or inhibitory (cTBS) stimulation over the left dorsolateral pre-frontal cortex (DLPFC), two other actively stimulated the right DLPFC and finally a sham stimulation group. An oddball based auditory P300 was performed just before a single session of iTBS, cTBS or sham stimulation and repeated immediately after. P300 mean latency comparison between the pre- and post-TBS stimulation stages revealed significantly faster post stimulation latencies only when iTBS was performed on the left hemisphere (p = 0.003). Right and left hemisphere cTBS significantly delayed P300 latency (right p = 0.026; left p = 0.000). Multiple comparisons for N200 showed slower latencies after iTBS over the right hemisphere. No significant difference was found in amplitude variation. TBS appears to effectively influence neural networking involved in P300 formation, but effects seem distinct for iTBS vs cTBS and for the right or the left hemisphere. P300 evoked potentials can be an effective and practical tool to evaluate transcranial magnetic stimulation related outcomes.
- Comunicação no espaço público: a publicidade de guerrilha em PortugalPublication . Silva, Ricardo; Elias, Herlander AlvesO sector da comunicação, nomeadamente a publicidade, enfrenta um reconhecido período de saturação. As marcas digladiam-se cada vez mais e de uma forma feroz para ganhar a atenção de um público cada vez mais disperso, que desenvolveu já mecanismos de rejeição aos tradicionais suportes através dos quais a publicidade veicula as suas mensagens. Num momento em que os meios de informação e as novas tecnologias estão cada vez mais acessíveis ao consumidor, é previsível que este se divorcie voluntariamente da forma tradicional como perceciona a publicidade. Perante essa adversidade, as marcas sentem necessidade em se reinventar a si próprias e à forma como desencadeiam o seu processo de comunicação, centrando agora toda a sua atenção no consumidor, explorando e antecipando as suas necessidades, ao mesmo tempo que desejam promover “experiências de marca”, que revolucionem o modo como as marcas são percecionadas pelo público. Aqui, ganha destaque a publicidade de guerrilha, uma nova forma de comunicação de marcas, que ao potenciar ao máximo os recursos disponíveis, cria situações surpreendentes e inusitadas que usam a interação entre público e marcas, para que estas perdurem na mente do público como algo mais que um logotipo por detrás de um produto. Pretende-se com a publicidade de guerrilha criar uma relação com o potencial consumidor para que, mesmo que este não compre o produto, o possa recordar sempre de um modo diferente.
- Traditional wooden houses in Maringá (Brazil): ICT in planning researchPublication . Gonino, Camila Nakamura; Virtudes, Ana L.; Silva, RicardoIn many cities, the examples of traditional architecture are being replaced by contemporary buildings, without any strategies in order to preserve a specific period of the urban and housing histories. These legacies are witnesses of particular features in terms of local communities, societies, political environments, urban morphologies or architectural languages. In this sense, this article presents the case study of the traditional wooden houses in the city of Maringá in Paraná (Brazil). There is a set of buildings which still remain among the existing urban fabric. However, every year some of them are destroyed in order to give room for new ways of designing the city. The methodological approach is based on the ICT (information and communication technologies) as a tool to study the features of these traditional wooden buildings.
