Refletindo sobre a prática pedagógica e investigando sobre a utilização de materiais não estruturados em contexto de jardim de infância
Publication . Lopes, Diana da Cruz; Rodrigues, Marina Vitória Valdez Faria
O presente relatório de Prática de Ensino Supervisionada foi realizado no âmbito do Mestrado em Educação Pré-Escolar. Este pretende apresentar o meu percurso de formação como educadora de infância e uma vertente como investigadora. O relatório apresenta três partes distintas, a primeira onde reflito sobre a minha experiência em contexto de creche bem como algumas das aprendizagens construídas ao longo da experiência, de uma forma reflexiva. A segunda parte reflete acerca de um contexto de jardim de infância de vertente pública em que foi implementada a abordagem por projeto. Na terceira parte é abordada a experiência num outro contexto de jardim de infância de carácter público bem como as aprendizagens e desafios que a mesma trouxe. A terceira parte para além da dimensão reflexiva, apresenta também um estudo de natureza investigativa, de carácter qualitativo, seguindo um paradigma interpretativo. Esta investigação foi desenvolvida com um grupo de crianças com idades compreendidas entre os três e os seis anos e pretendeu investigar sobre as aprendizagens proporcionadas pela exploração livre de materiais não estruturados. Os resultados obtidos evidenciam que esta exploração promove aprendizagens no âmbito das diferentes áreas de conteúdo definidas nas OCEPE.

A 1.2V 900nW conductance converter
Publication . Miranda, Nuno; Morais, Raul
This article describes a new electrical conductance converter method suitable for very low power applications, where energy constraints prevails over speed and measurement accuracy. Method idea gather voltage time integration and shopper stabilization techniques to process noisy low amplitude signals and to overcome severe limitations of weak inversion channel CMOS circuitry. Main features and tradeoffs are exploited. A 1.2V ASIC implementation on standard 0.35μm CMOS schematics is also presented. Post-layout simulations shows a total power consumption lower than 900nW including current source excitation inherent to the conductance measurement. Such low power consumption allows the measurement of several physical parameters on self-powered wireless networks.

Business Intelligence in higher education: Enhancing the teaching-learning process with a SRM system
Publication . Piedade, Maria Beatriz; Santos, Maribel Yasmina
Promoting students success requires the implementation of processes and mechanisms that allows the closely monitoring of the students academic activities. Although essential, the activities involved in this complex process do not take place in many higher education institutions due to the lack of appropriate practices and an adequate technological support that sustain these practices. To overcome this complex problem, a conceptual and a technological infrastructure was proposed and integrated into a Student Relationship Management (SRM) system. The SRM system is associated with Business Intelligence concepts and technologies used to obtain knowledge about the students and to support the decision making process. To validate the SRM system relevance, a set of applications cases were carried out in real contexts and supported by the implemented prototype. This paper presents some of the results obtained through the prototype implementation and on the analysis of the several actions that were carried out under the principles of the SRM practice.

Unveiling the power of supplier-country image on B2B customers' perceptions: Beyond the product’s beauty
Publication . Crespo, Cátia Fernandes; Crespo, Nuno Fernandes; Silva, Susana C.
Researchers in business-to-business (B2B) sectors often assume that findings regarding country-of-origin (COO) effects on end consumers can be directly applied to the industrial marketing context. This tendency to generalize can result in an inaccurate understanding of how buyers perceive COO information in B2B scenarios. This study investigates the effect of supplier-country image on international customers’ perceptions of both perceived product quality and relationship quality in a B2B market environment. We further examine the consequences of perceived product quality and relationship quality on supplier awareness and customer loyalty. Data collected from 182 international B2B buyers in the Portuguese footwear, molds, and wood products and furniture industries were analyzed using structural equation modeling (SEM). The results indicate that supplier-country image influences the relationship quality dimensions (trust, commitment, and satisfaction) and perceived product quality. Moreover, trust and commitment enhance customer loyalty, while trust and satisfaction leverage supplier awareness. In contrast, perceived product quality only influences customer loyalty, albeit to a weaker extent. Thus, relationship quality plays a more significant role than perceived product quality in influencing supplier awareness and customer loyalty in B2B environments. These results challenge the notion that the impact of COO on end consumers can be equally applied in B2B contexts, and they expand our understanding of how supplier-country image affects relationship quality in the industrial setting. Furthermore, they draw managers’ attention to the importance of mitigating a potentially negative COO image through measures aimed at improving relationships.

The Effect of Celebrity Endorsement on Brand Equity: A Cross Cultural Comparison
Publication . Crespo, Cátia Fernandes; Ribeiro, Fábio Matos; Ferreira, Alcina Gaspar; Popa, Victor
Celebrity endorsement has become a popular advertising strategy on a global scale. However, although responses to celebrity endorsement are considered to diverge across cultures, cross-cultural research on celebrity endorsement as an advertising strategy is argued to be scarce. The purpose of this research is to extend the current literature by examining cross-cultural similarities and differences in celebrity endorsement effectiveness. We investigate the impact of celebrity endorsement strategies on brand image and brand identification and how these factors, in turn, influence brand equity, across markets. Data were collected through an online survey addressed to two markets: Portugal, and Moldova. A total of 365 valid answers were obtained, 195 from the Portuguese market, and 170 from the Moldovan market. Partial least squares structural equation modeling was used to test the hypotheses. The results indicate that the attitude toward the celebrity endorser has a significantly positive effect on brand image and a significantly positive effect on brand identification, only in the Moldovan market. In both markets, brand image and brand identification positively influence brand equity.
