Descrever e interpretar visões do mundo: consciência crítica da linguagem e literacia cultural em contexto de ensino do Português como Língua Estrangeira

Publication . Alexandre, Marta; conde, ines

Learning a foreign language involves more than merely developing skills related to the knowledge and use of grammatical structures for specific communicative purposes. It is a process that also integrates the recognition of discursive configurations, often ideological, that may be revealed in texts, particularly in specific cultural and social contexts of production and dissemination. Within a globalised world and in various communication contexts, often with an intercultural dimension, hegemonic discourses are produced and disseminated around beliefs, identities, events and geographies, which in some way sustain and naturalise unequal power relations and areas of tension and conflict. This work aligns with theoretical perspectives that recognise the importance of discursive and critical shifts in language teaching and intercultural communication, as well as with approaches that understand language as a social practice, namely Critical Multimodal Discourse Analysis. It is argued that teaching and learning contexts for Portuguese as a Foreign Language (PLE) benefit from training critical awareness of language through its different modes of realisation, and from teaching cultural literacy. In particular when framed by these approaches and equipped with strategies that facilitate the acquisition and application of socially committed textual analysis tools, PLE teaching methodologies enable students to question and evaluate texts in Portuguese in relation to their everyday and professional practices. They also facilitate the mastery of different modes of meaning and an understanding of how they work, making this explicit. To begin with, this article describes and explains a learning sequence for critical discourse analysis of authentic multimodal texts in Portuguese, involving classroom tasks and independent work. The sequence was implemented in the context of the Discourse and Multimodality course unit, part of the Applied Portuguese Language course taught at the School of Education and Social Sciences of the Polytechnic Institute of Leiria to Chinese students in the 2023/2024 academic year. In this context, the portfolio resource is highlighted as an element of individual application and assessment of knowledge, and the results of the application of the proposals are discussed, with reference to works describing and interpreting elements of connotation and interdiscursive configurations in texts selected by the students and included in their portfolios. As a result, the textual analysis work carried out by the students reveals that exposure to authentic texts, which allows them to describe and interpret verbal and visual choices, and the types of relationships that different modes establish between themselves, enables them to develop a critical and socially committed cultural awareness. There was evidence of students identifying and questioning the interrelationship between language, culture, economics, ideology and power, as well as the materiality of representation, both verbal and visual, and, very importantly, the social and communicative specificities of the texts.

Experimental and numerical characterization of single-phase pressure drop and heat transfer enhancement in helical corrugated tubes

Publication . Cruz, Gonçalo G.; Mendes, Miguel A. A.; Pereira, José M. C.; Santos, H.; Nikulin, A.; Moita, Ana S.

The internal flow in corrugated tubes of different helical pitch, covering from the laminar to turbulent regime, was studied in order to characterize the three-dimensional flow and the influence of corrugation geometry on pressure drop and convective heat transfer. With water as working fluid and an imposed wall heat flux, ranging from around 4 to 33 kW/m2, a numerical model was developed with a CFD commercial software, where k−ω SST was used to model turbulence. Experimental tests were performed covering Reynolds numbers in the range from around 300 up to 5000, which allowed to identify the transition region and validate the numerical model. The results show that due to the swirl induced by the corrugation, the critical Reynolds number for the start of transition to turbulent flow is reduced. The thermal performance factor, which quantifies the heat transfer enhancement at the expense of pressure drop, was used to compare the corrugated tubes against the reference case of smooth tube. Based on this, all investigated corrugated geometries performed better than the smooth tube, except for low Reynolds numbers (Re<500) in the laminar regime. Overall, the corrugated tube with the lowest pitch showed a clearly better performance for the intermediate range of Reynolds numbers (1000

Green Marketing and Green Brand – The Toyota Case

Publication . Simão, Lídia; Lisboa, Ana

The main aim of this study is to contextualize sustainability and call for its consideration in firms’ management, namely via green marketing and green brand. Although the concept of sustainable development appeared in the 1970s, only recently has it been incorporated by firms. Development, to be sustainable, has to satisfy the needs of current generations, without compromising the ability of future generations to satisfy theirs. This requires a balance in managing social, economic and environmental aims, both current and future. Given the increasing evidence of environmental problems, the awareness of the need for sustainability has been expanding, at the individual and at the corporate level. Environmentally responsible firms obtain multiple benefits, such as cost reduction (due to the lower resource consumption, such as water or energy), profit increase (from recycling and residuals reuse), production process enhancement (given the cleaner and more efficient technologies), corporate image upgrading, improvement of brand awareness and value as well as performance. Oppositely, firms associated to non-sustainable actions are impaired in those areas. In the scope of a green strategy, a green brand obtains attributes and benefits related to the reduction of the brand’s environmental impact. As such, it should promote the perception of an environmentally healthy brand and disclose such benefits to the more environmentally aware consumers. We present the case of Toyota, a brand with patent and acknowledged efforts in what regards sustainability. It is a worldwide reference of corporate responsibility and of a successful use of green marketing. The brand’s challenge to reach important environmental goals until 2050, demonstrates its commitment and endeavor in multiple crucial aspects of sustainability management. Therefore, Toyota is in a prominent position as a “global green brand”.

UAV Flight Simulator to Improve Elders’ Quality of Life

Publication . Crespo, Christian Bustamante; Idrovo, Graciela Guerrero; Rodrigues, Nuno; Pereira, António

The quality of life in older people deteriorates faster, depending if these have a sedentary lifestyle. Technology is used as a tool in various fields and there are some applications that have been developed to encourage sports through entertainment, this is the case of the Nintendo Wii. The positive impact of this kind of application has been the base in the development of this research. Our proposal focuses on the easy handling of a drone by sensing arm movements through wearable devices, and providing an immersive experience of being in a different place using virtual reality glasses. The aim is to promote the user's cognitive development, due to the hand-eye coordination required to control the drone. Finally, this research, manages to integrate virtual reality with Bluetooth technologies, establishing real-time communication with wearable devices and human movement.

Implemented Data Mining and Signal Management Systems on Spontaneous Reporting Systems’ Databases and their Availability to the Scientific Community - A Systematic Review

Publication . Lima, Luis Miguel de Almeida Vieira; Nunes, Nuno Goncalo Sales Craveiro; Dias, Pedro Goncalo Pires da Silva; Marques, Francisco Jorge Batel

Adverse drug reactions’ spontaneous reporting systems are an important element in worldwide pharmacovigilance, gathering potentially useful information for post-marketing drug safety surveillance. Data mining and signal management systems, providing the capability of reading and interpreting these systems’ raw data (data that has not been subjected to processing or any other manipulation), improve its analysis process. In order for this analysis to be possible, both data mining and signal management systems and raw data should be available to researchers and the scientific community. The purpose of this work was to provide an overview of the spontaneous reporting systems databases reported in literature as having implemented a data mining and signal management system and the implementation itself, evidencing their availability to researchers. A systematic review was carried out, concluding that they are freely provided to researchers within institutions responsible for maintaining the spontaneous reporting systems, but not to most researchers within the scientific community.
