The human genome has millions of genetics variants that can affect gene expression. These variants are known as cis-regulatory variants and are responsible for intra-species phenotypic differences and individual susceptibility to disease. One of the diseases affected by cis-regulatory variants is breast cancer. Breast cancer is one of the most common cancers, with approximately 4500 new cases each year in Portugal. Breast cancer has many genes mutated and TP53 has been shown to be relevant for this disease. TP53 is one of the most commonly mutated genes in human cancer and it is involved in cell cycle regulation and apoptosis. Previous work by Maia et al has shown that TP53 has differential allelic expression (DAE), which suggests that this gene may be under the influence of cis-regulatory variants. Also, its DAE pattern is totally altered in breast tumours with normal copy number. We hypothesized that cis-regulatory variants affecting TP53 may have a role in breast cancer development and treatment. The present work aims to identify the cis-regulatory variants playing a role in TP53 expression, using in silico, in vitro and in vivo approaches. By bioinformatic tools we have identified candidate cis-regulatory variants and predicted the possible transcription factor binding sites that they affect. By EMSA we studied DNA-protein interactions in this region of TP53. The in silico analysis allowed us to identified three candidate cis-regulatory SNPs which may affect the binding of seven transcription factors. However, the EMSA experiments have not been conclusive and we have not yet confirmed whether any of the identified SNPs are associated with gene expression control of TP53. We will carry out further experiments to validate our findings.

The purpose of this research is to develop and validate a measurement scale to assess golf destinations’ brand personality and therefore to perceive the destination personality of the Algarve as a golf destination. Based on literature review on human personality, brand personality, destination brand image and marketing scales validation procedures, an initial 36 unrepeated items were the base for a survey instrument. Those items were generated from the literature, from the results of individual interviews with experts in tourism and golf in the Algarve and from promotional texts in golf- related websites. After content validation, the items were allocated into categories of attributes by a panel of expert judges. A survey was then applied to a convenient sample of 600 golf players in the Algarve, and 545 (valid) questionnaires were analysed to refine the scale. Golf players assessed the components of the relational brand personality (functional, symbolic and experiential) as well as the Algarve as a golf destination. A taxonomy of brand personality was developed and tested in the Algarve as it is recognized as one of the world best golf destination. The developed taxonomy of brand personality was assessed in two ways: 1) through the overall perception of the Algarve as a golf destination and 2) through the perception of specific attributes of the destination grouped into three main categories (functional, symbolic and experiential). Therefore, two multi-dimensional brand personality models were estimated by using structural equation modelling. Findings of this study indicate that golf players ascribe personality characteristics to destinations. The brand personality of the Algarve is translated into three main dimensions enjoyableness, distinctiveness and friendliness when tourists/golf players reveal their overall perception of the destination. The brand personality of golf destination Algarve is reflected in the dimensions reliability, hospitality, uniqueness and attractiveness when tourists assess the components of the relational brand personality. Refined scales consisting of 10 and 12 items were finally derived meeting both reliability and validity requirements. This study does not replicate Aaker’s (1997) personality dimensions and very little parallelism can be drawn with Aaker’s (1997) brand personality scale since only three items from her scale were validated in both models: friendly and cheerful, (sincerity), reliable (competence). The same is verified concerning the ‘Big-five’. The human personality traits (HPT) validated to describe golf destinations personality are only four helpful, pleasant (agreeableness), relaxed (emotional stability), and innovative (intellect or openness). As far as destination image descriptors (DID) are concerned, the items appealing, relaxed and safe were validated, while traits suggested by the interviews and website promotional texts such as calm, natural, spectacular, unique, welcoming, and the best (destination-specific traits) appear to be appropriate to describe the personality of a golf destination. The results suggest that the overall perception of the Algarve´s brand personality is described by the dimensions enjoyableness, distinctiveness and friendliness. Moreover, the relational perspective revealed that the functional attributes of the destination are described by the dimension reliablility, while the symbolic attributes are described by the dimensions hospitablility and uniqueness and finally its experiential attributes are described by the dimension attractiveness. These results show that a golf destination´s brand personality should not just be based on good golf practices. Theoretical and practical implications are discussed in the context of destination brand personality.

O trabalho aqui proposto tem como objectivo central, a realização de análises ao conjunto dos recipientes cerâmicos pertencentes ao povoado da Sala nº1. Repertório esse, que se baseou no acervo retirado do sítio arqueológico Sala nº1, intervencionado pelo Professor Victor S. Gonçalves (1988, 1989 e 1995). As análises e descrições efectuadas foram sempre norteadas para a tentativa de estabelecer uma sequência de formas que se pudesse verificar quanto à sua normalização e frequência nos contextos presentes ao povoado da Sala nº1. Traduzindo nessa realidade, a diacronia transversal entre os estratos arqueológicos pertencentes ao Neolítico final e os estratos pertencentes ao Calcolítico. Tendo sempre como parâmetros de análise, as metodologias e critérios descritivos dos recipientes cerâmicos, presentes nos trabalhos publicados sobre as realidades cronológicas semelhantes no Sul de Portugal. O próprio conjunto de recipientes cerâmicos aqui analisado foi submetido a essas metodologias, com fim de obter primordialmente as formas e as tipologias a que pertencem. Nesse sentido procurei criar um quadro de referência local e regional, e posteriormente coloca-lo num enquadramento geral do Neolítico final e início do Calcolítico do Alentejo Médio, tentando verificar as similitudes nos quadros tipológicos existentes, como os estabelecidos por Carlos Tavares da Silva e Joaquina Soares. Sendo este um estudo que abrange um tempo cronológico de praticamente 1500 anos, premiei através da amplitude dos contornos que moldaram esta análise, algumas perspectivas possíveis. Quer ao nível das tipologias, quer ao nível das estratégias de ocupação do território, aplicáveis para o espaço e o tempo em análise. Verificando a realidade escassa nos contextos alentejanos (publicados), em que a cultura material se integra numa estratigrafia e cronologias com uma diacronia semelhante à do povoado da Sala nº1. Tentei integrar este povoado num estudo que não sendo comparativo, tivesse essa componente em relação às tipologias e formas cerâmicas identificadas. Procurou-se dar enfase à realidade artefactual das taças carenadas, e à sua possível evolução para formas mais adaptáveis ao uso e consumo quotidiano das comunidades contemporâneas das fases Calcolíticas do povoado.
