Supermarkets in Portugal: corporate social responsibility image, attitude towards the brand and purchase intention

Recently, companies developed strategies which may influence their Corporate Social Responsibility (CSR) image. This paper discusses the image of four different supermarkets with stores in Portugal. The research compares CSR image and brand attitude of the four supermarkets. Empirical evidence shows that different supermarkets belonging to the same company have different CSR image and brand attitude. The research also confirms that there is positive correlation between CSR image and attitude towards the brand. Further, the results offer empirical evidence that CSR image and brand attitude influence purchase intention of supermarket brands. Finally, brand purchase intention is highly influenced by attitude towards the brand than CSR image.

Portuguese-Americans in the East Coast: is “crystallization” a myth?

In the last but one census of the population in the US, I had to respond as a foreigner resident, and when I was asked about my race, I chose to answer the ways I had heard the activists of the civil rights movement used to do in the US, when color blindness was an important thing to fight for – to “RACE” I added “HUMAN”...

Image upsampling algorithms applied on Nuclear Medicine: comparision of hqnx and nxSaI algorithms families with two interpolation algorithms - nearest neighbour and bicubic interpolation

Introduction: Image resizing is a normal feature incorporated into the Nuclear Medicine digital imaging. Upsampling is done by manufacturers to adequately fit more the acquired images on the display screen and it is applied when there is a need to increase - or decrease - the total number of pixels. This paper pretends to compare the “hqnx” and the “nxSaI” magnification algorithms with two interpolation algorithms – “nearest neighbor” and “bicubic interpolation” – in the image upsampling operations. Material and Methods: Three distinct Nuclear Medicine images were enlarged 2 and 4 times with the different digital image resizing algorithms (nearest neighbor, bicubic interpolation nxSaI and hqnx). To evaluate the pixel’s changes between the different output images, 3D whole image plot profiles and surface plots were used as an addition to the visual approach in the 4x upsampled images. Results: In the 2x enlarged images the visual differences were not so noteworthy. Although, it was clearly noticed that bicubic interpolation presented the best results. In the 4x enlarged images the differences were significant, with the bicubic interpolated images presenting the best results. Hqnx resized images presented better quality than 4xSaI and nearest neighbor interpolated images, however, its intense “halo effect” affects greatly the definition and boundaries of the image contents. Conclusion: The hqnx and the nxSaI algorithms were designed for images with clear edges and so its use in Nuclear Medicine images is obviously inadequate. Bicubic interpolation seems, from the algorithms studied, the most suitable and its each day wider applications seem to show it, being assumed as a multi-image type efficient algorithm.

Traduzir Cesário Verde - Cesário Verde intraduzível

It is main goal of this article to stimulate the debate and reflection on Translation Studies. Based on Cesário Verde‘s poem O Sentimento dum Ocidental (1880) we will discuss the effectiveness and applicability of poetry translation. Since the beginning of the XX century Cesário Verde and his work have been studied on an international range. We may therefore make reference to outnumbered translations of his poems in English, French, German, Italian, and Czech. Poetry translation raises however several difficulties which may affect the comprehension, interpretation and analysis not only of this author but also of his texts. In this manner we will naturally confront as well some of the most relevant items for Translation Studies, namely: Translation purposes and criteria; Translation necessity, possibility and usefulness. We invite you thus to observe the rich and complex Poetry-Translation relation within the analysis of one Cesário‘s poem in Italian, English, German and French.

Mechanisms for reflection-based monitoring of real- time systems

Monitoring is a very important aspect to consider when developing real-time systems. However, it is also important to consider the impact of the monitoring mechanisms in the actual application. The use of Reflection can provide a clear separation between the real-time application and the implemented monitoring mechanisms, which can be introduced (reflected) into the underlying system without changing the actual application part of the code. Nevertheless, controlling the monitoring system itself is still a topic of research. The monitoring mechanisms must contain knowledge about “how to get the information out”. Therefore, this paper presents the ongoing work to define a suitable strategy for monitoring real-time systems through the use of Reflection.

Relatório de Estágio em Educação Pré-Escolar

O relatório de estágio de qualificação profissional desenvolveu-se no âmbito da Unidade Curricular (UC) de Prática Pedagógica Supervisionada, inserida no Mestrado em Educação Pré- Escolar, nos contextos de creche e pré-escolar. Esta integração implicou a mestranda numa atitude investigativa, traduzida no aprofundamento dos referenciais teóricos abordados na referida UC, que permitiu desenvolver uma atitude indagadora e reflexiva, de modo a aliar saberes teóricos à prática e mobilizá-los em contexto. Efetivando a sua prática pedagógica através da observação, recolha de dados, análise sistemática da ação e reflexão crítica permanente, apoiou-se na metodologia de investigaçãoação, que segundo Elliot (1991) constitui um processo reflexivo, que envolve a mudança de teorias e práticas, permitindo ligar a autoavaliação ao desenvolvimento profissional. A prática pedagógica revista neste documento parte da convicção da mestranda relativamente à importância da observação, na mesma perspetiva de Gonçalves (2006): “se soubermos observar, saberemos compreender, se soubermos compreender, saberemos intervir e se soubermos intervir, saberemos melhorar, estaremos a conferir ao exercício de observação e análise da relação educativa o seu verdadeiro estatuto de instrumento de desenvolvimento pessoal/profissional do formando” (p.72). Foi assim que a mestranda solidificou a construção da sua imagem de criança, encarando-a como ativa e competente, almejando que essa visão se refletisse nas suas planificações, que identificavam necessidades e interesses das crianças, e consequentemente na sua ação. A co construção de saberes e a cooperação assumiram particular relevância no processo de formação e desenvolvimento profissional, proporcionado pelos intervenientes no contexto educativo: par de formação, educadoras, supervisora, pais e comunidade.

POSIX trace based behavioural reflection

Traditional Real-Time Operating Systems (RTOS) are not designed to accommodate application specific requirements. They address a general case and the application must co-exist with any limitations imposed by such design. For modern real-time applications this limits the quality of services offered to the end-user. Research in this field has shown that it is possible to develop dynamic systems where adaptation is the key for success. However, adaptation requires full knowledge of the system state. To overcome this we propose a framework to gather data, and interact with the operating system, extending the traditional POSIX trace model with a partial reflective model. Such combination still preserves the trace mechanism semantics while creating a powerful platform to develop new dynamic systems, with little impact in the system and avoiding complex changes in the kernel source code.

The role of cultural mega events in the enhancement of city’s image attributes: differences between engaged and attendee participants

In a time of fierce competition between regions, an image serve as a basis to develop a strong sense of community, which fosters trust and cooperation that can be mobilized for regional growth. A positive image and reputation could be used in the promotional activities of the region benefiting all the stakeholders as a whole. Mega cultural events are frequently used to attract tourists and investments to a region, but also to enhance the city’s image. This study adopts a marketing/communication perspective of city’s image, and intends to explain how the image of the city is perceived by their residents. Specifically, we intend to compare the perceptions of residents that effectively participated in the Guimarães European Capital of Culture (ECOC) 2012 (engaged residents), and the residents that only assisted to the event (attendees). Several significant findings are reported and their implications for event managers and public policy administrators presented, along with the limitations of the study

Quantification and viability analyses of Pseudokirchneriella subcapitata algal cells using image-based cytometry

This work aims to evaluate the feasibility of using image-based cytometry (IBC) in the analysis of algal cell quantification and viability, using Pseudokirchneriella subcapitata as a cell model. Cell concentration was determined by IBC to be in a linear range between 1 × 105 and 8 × 106 cells mL−1. Algal viability was defined on the basis that the intact membrane of viable cells excludes the SYTOX Green (SG) probe. The disruption of membrane integrity represents irreversible damage and consequently results in cell death. Using IBC, we were able to successfully discriminate between live (SG-negative cells) and dead algal cells (heat-treated at 65 °C for 60 min; SG-positive cells). The observed viability of algal populations containing different proportions of killed cells was well correlated (R 2 = 0.994) with the theoretical viability. The validation of the use of this technology was carried out by exposing algal cells of P. subcapitata to a copper stress test for 96 h. IBC allowed us to follow the evolution of cell concentration and the viability of copper-exposed algal populations. This technology overcomes several main drawbacks usually associated with microscopy counting, such as labour-intensive experiments, tedious work and lack of the representativeness of the cell counting. In conclusion, IBC allowed a fast and automated determination of the total number of algal cells and allowed us to analyse viability. This technology can provide a useful tool for a wide variety of fields that utilise microalgae, such as the aquatic toxicology and biotechnology fields.
