Motivations to visit and image destination of Guimarães: differences between Portuguese and foreign tourists during 2012 Guimarães European Capital of Culture (ECOC)

Guimarães hosted the European Capital of Culture (ECOC) during the year of 2012. This study investigates the differences between Portuguese and foreign tourists regarding the main motivations to visit Guimarães and the retained perceived image of the destination. To achieve that purpose a survey was administered to 390 tourists that visited the city during the cultural event. The results show that tourists who visited Guimarães are relatively young, wealthy, employed and well educated. They are touring around the northern part of the country which includes an itinerary beginning in Porto, and extended to other important neighboring cities such as Braga or Viana do Castelo. The main motivations to visit the city, for both Portuguese and foreign tourists, are its historical heritage and the title of ECOC, the associated cultural events and celebrations that take place during 2012. However, these items were more valued by foreigners than Portuguese tourists. Using a factor analysis the tourists’ perceived attributes of Guimarães were described in four dimensions: “material heritage”, “intangible heritage”, “cultural performance”, and “sport and education”. Although foreigners and nationals perceived the tourism attributes of the city differently, the comparison of the mean scores of the four factors across Portuguese and foreigner tourists reveals that the most valued and least valued factors are common to both groups.

An image processing application for quantification of protein aggregates in Caenorhabditis elegans

Protein aggregation became a widely accepted marker of many polyQ disorders, including Machado-Joseph disease (MJD), and is often used as readout for disease progression and development of therapeutic strategies. The lack of good platforms to rapidly quantify protein aggregates in a wide range of disease animal models prompted us to generate a novel image processing application that automatically identifies and quantifies the aggregates in a standardized and operator-independent manner. We propose here a novel image processing tool to quantify the protein aggregates in a Caenorhabditis elegans (C. elegans) model of MJD. Confocal mi-croscopy images were obtained from animals of different genetic conditions. The image processing application was developed using MeVisLab as a platform to pro-cess, analyse and visualize the images obtained from those animals. All segmenta-tion algorithms were based on intensity pixel levels.The quantification of area or numbers of aggregates per total body area, as well as the number of aggregates per animal were shown to be reliable and reproducible measures of protein aggrega-tion in C. elegans. The results obtained were consistent with the levels of aggrega-tion observed in the images. In conclusion, this novel imaging processing applica-tion allows the non-biased, reliable and high throughput quantification of protein aggregates in a C. elegans model of MJD, which may contribute to a significant improvement on the prognosis of treatment effectiveness for this group of disor-ders

Certification and integration of management systems: the experience of Portuguese small and medium enterprises

The purpose of this study was to characterize the situation of Portuguese Small and Medium Enterprises (SMEs) concerning the certification of their Quality Management Systems (QMS), Environmental Management Systems (EMS) and Occupational Health and Safety Management Systems (OHSMS), in their individually form, to identify benefits, drawbacks and difficulties associated with the certification process and to characterize the level of integration that has been achieved. This research was based on a survey carried out by the research team; it was administered to 46 Portuguese SMEs. Our sample comprised 20 firms (43%) from the Trade/Services activity sector, 17 (37%) from the Industrial sector, 5 (11%) from the Electricity/Telecommunications sector and 4 (9%) from the Construction area. All SMEs surveyed were certified according to the ISO 9001 (100%), a quarter of firms were certified according to the ISO 14001 (26.1%) and a few certified by OHSAS 18001 (15.2%). We undertook a multivariate cluster analysis, which enabled grouping variables into homogeneous groups or one or more common characteristics of the SMEs participating in the study. Results show that the main benefits that Portuguese SMEs have gained from the referred certifications have been, among others, an improvement of both their internal organization and external image. We also present the main difficulties in achieving certification. Overall, 7 of the Portuguese SMEs examined indicated that the main benefits of the IMS implementation management included costs reduction, increased employee training and easier compliance of legislation. The respective drawbacks and difficulties are also presented. Finally, we presented the main integrated items in the certified Portuguese SMEs we examined.

Motivation and Benefits of Implementation and Certification according ISO 9001 – the Portuguese Experience

The aim of the research is to analyze the different aspects associated with the motivation and benefits of certified ISO 9001 companies in Portugal. A total of 426 certified Portuguese companies were surveyed. The response rate was equal to 61.03 percent. Our results suggest that the main motivation for certification were “improvement of quality”, “improvement of company image”, “marketing advantage”, “give empowerment to workers / capturing workers knowledge” and “cost reduction”. The main benefits that Portuguese companies have gained from the referred certification have been, among others, the improvement of “procedures”, beneficial effect on the “company’s image”, the improvement of quality products/services, increase of the “customer satisfaction”, improvement of “on-time delivery”; improvement the “morale” of workers’ increase in productivity and decrease of “production costs”, among others. The surveyed firms belong only to the Minho region of the north of Portugal. This paper aims to provide a contribution to the research related to the motivation and benefits associated to the quality management systems. The selection of the motives and benefits were validated through statistical analysis and the relationship between expected and perceived benefits was discussed.

Automated image analysis of lung branching morphogenesis from microscopic images of fetal rat explants

Background: Regulating mechanisms of branching morphogenesis of fetal lung rat explants have been an essential tool for molecular research. This work presents a new methodology to accurately quantify the epithelial, outer contour and peripheral airway buds of lung explants during cellular development from microscopic images. Methods: The outer contour was defined using an adaptive and multi-scale threshold algorithm whose level was automatically calculated based on an entropy maximization criterion. The inner lung epithelial was defined by a clustering procedure that groups small image regions according to the minimum description length principle and local statistical properties. Finally, the number of peripheral buds were counted as the skeleton branched ends from a skeletonized image of the lung inner epithelial. Results: The time for lung branching morphometric analysis was reduced in 98% in contrast to the manual method. Best results were obtained in the first two days of cellular development, with lesser standard deviations. Non-significant differences were found between the automatic and manual results in all culture days. Conclusions: The proposed method introduces a series of advantages related to its intuitive use and accuracy, making the technique suitable to images with different lightning characteristics and allowing a reliable comparison between different researchers.

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.

O IMPACTO FINANCEIRO DAS AUDITORIAS DA QUALIDADE NAS EMPRESAS PORTUGUESAS

This paper discusses the main theme the financial implications that Portuguese companies with the implementation and subsequent certification of the Quality System and respective Quality Audits. The literature review shows that companies do not publish financial results on the subject in question, making it necessary to acquire information through a questionnaire. About 126 questionnaires were sent. Our sample is however 32 validados.Pode to complete questionnaires that the top 5 overall benefits or indirect financial benefits for Portuguese companies were, respectively: improving internal organization; improving the company's image; increasing customer satisfaction; continuous improvement in customer service; improving competitive position. In terms of direct financial benefits the 3 main benefits obtained by the companies were: turnover increase; Performance (cost reduction); Increased business productivity. So it is expected to contribute to the knowledge of the impact, notably financial of Quality Management Systems and respective audits in Portuguese companies.

Improving The Robustness Of Interventional 4D Ultrasound Segmentation Through The Use Of Personalized Shape Priors

While fluoroscopy is still the most widely used imaging modality to guide cardiac interventions, the fusion of pre-operative Magnetic Resonance Imaging (MRI) with real-time intra-operative ultrasound (US) is rapidly gaining clinical acceptance as a viable, radiation-free alternative. In order to improve the detection of the left ventricular (LV) surface in 4D ultrasound, we propose to take advantage of the pre-operative MRI scans to extract a realistic geometrical model representing the patients cardiac anatomy. This could serve as prior information in the interventional setting, allowing to increase the accuracy of the anatomy extraction step in US data. We have made use of a real-time 3D segmentation framework used in the recent past to solve the LV segmentation problem in MR and US data independently and we take advantage of this common link to introduce the prior information as a soft penalty term in the ultrasound segmentation algorithm. We tested the proposed algorithm in a clinical dataset of 38 patients undergoing both MR and US scans. The introduction of the personalized shape prior improves the accuracy and robustness of the LV segmentation, as supported by the error reduction when compared to core lab manual segmentation of the same US sequences.

Cultural mega-events and the enhancement of a city's image: differences between engaged participants and attendees

A city’s image can serve as the basis upon which to develop a strong sense of community. This, in turn, fosters trust and cooperation which may attract tourists and investment, and drive regional economic growth. One strategy to enhance a city’s image is to host cultural mega-events. This study focuses on Guimarães, one of the European Capitals of Culture of 2012, and adopts a marketing communication perspective to explore issues of city image. The objective of the study reported was to understand whether images of Guimarães improved after it hosted the cultural mega-event. To attain this goal, we compare the perceptions of residents who participated in the event (engaged participants) and attendees. Several significant findings are reported and their implications for event managers and public policy administrators are presented, along with the limitations of the study.
