Valor económico da onda

Dissertação de Mestrado, Ciências Económicas e Empresariais, 30 de Janeiro de 2017, Universidade dos Açores.Pretendeu-se com esta Tese de Mestrado caracterizar os praticantes de surf em Portugal e nos Açores e estimar o potencial dos desportos de ondas no desenvolvimento económico nacional e regional. Para a caracterização dos praticantes de surf foram validados 1654 inquéritos, sendo que 180 inquéritos foram respondidos nos Açores e 1474 em Portugal Continental. O inquérito utilizado foi elaborado pela Universidade Nova de Lisboa no âmbito do estudo Project Value of Waves Ocean Culture. Foram realizados inquéritos iguais nos Açores e em Portugal Continental o que permite uma comparação entre estas duas regiões. Foi realizada uma análise descritiva das respostas dadas às questões relacionadas com a qualidade dos spots bem como uma análise de variância onde se pretendeu encontrar os principais fatores relacionados com esta qualidade. Foram também estimados modelos custo de viagem individual, com base no modelo de Maveriks, que pretenderam explicar a frequência de visita às praias.ABSTRACT: This master’s thesis main purpose was to characterize the surfers in Portugal and in the Azores and estimate the potential of wave sports in the national and regional economic development. To characterize the surfers 1654 were validated, 180 questionnaires were answered in the Azores and 1474 questionnaires in mainland Portugal. The questionnaire was developed by Universidade Nova de Lisboa in the study Project Value of Waves Ocean Culture. Investigations were performed both in the Azores and mainland Portugal which allows a comparison between these two regions. A descriptive analysis addressed the question of the quality of spots as well and analysis of variance identified the main factors related to the quality of the spots. An individual travel cost, based on the Maveriks model, explaining the frequency of visits to beaches was estimated

Deteção da simulação de problemas de memória em contexto forense

Dissertação de mestrado integrado em Psicologia (área de especialização de Psicologia da Justiça)A avaliação da simulação é um procedimento indispensável em muitas avaliações neuropsicológicas, clínicas e forenses. Uma vez que as provas de avaliação neuropsicológicas se mostram incapazes de detetar a simulação de sintomas, outras metodologias devem ser seguidas. A utilização de Testes de Validade de Sintomas (TVS) é uma das técnicas mais promissoras para este mesmo fim. Neste estudo, procurámos desenvolver um novo TVS baseado no TOMM - Test Of Memory Malingering (Tombaugh, 1996) contento, no entanto, diversas alterações metodológicas, efetuadas com base nas conclusões de diversos estudos recentes, de forma a aumentar a eficácia e utilidade deste mesmo teste. Explorámos ainda qual o efeito de diversas variáveis na deteção da simulação de problemas de memória, nomeadamente, o tempo de resposta dos participantes, o treino dos avaliados e a ordem pela qual o TVS é aplicado na bateria de provas. Desenvolvemos um TVS (DETECTS – Teste de Deteção da Simulação de Problemas de Memória) completamente informatizado, com um tempo de aplicação reduzido e com pontos-de-corte eficazes, possuindo a prova um elevado índice de sensibilidade, especificidade e valor preditivo positivo e negativo. Em conjunto com a bateria de testes aplicada, a prova construída permitiu, para a amostra utilizada, que nenhum simulador fosse incorretamente classificado como detentor de uma perturbação mnésica legítima, e vice-versa.The evaluation of malingering is an essential procedure in most neuropsychological, clinical and forensic evaluations. Since neuropsychological tests are unable to detect malingering, other methods must be used for this purpose. One of the most promising procedures is the use of Symptom Validity Tests (SVT). In this study, we aimed to develop a new SVT, inspired on the TOMM - Test of Memory Malingering (Tombaugh, 1996), but with some modifications, based on recent findings from several studies, to increase the effectiveness and usefulness of this test. We also explored the effect of different variables on the detection of memory malingering, for instance, participants’ response time, participants training, and the order in which the SVT is applied within the neuropsychological test battery. Therefore, we developed a fully computerized test (DETECTS – Memory Malingering Detection Test), with a reduced application time, and with effective cut-off points as well as an excellent sensitivity, specificity, positive and negative predictive power values. When applied among the test battery, this test allowed us not to wrongly classify any malingerer as a subject with legitimate memory deficits and vice versa

Does labor mobility affect top management gender choices? : evidence from non-competition agreements

The phenomenon of discrimination is understood as having different causes, one of them being information-based. This theory suggests that the lack of individual-specific information leads people to judge others based on the perceived (and potentially biased) characteristics of the groups they belong to. Exploiting the fact that companies possess more accurate information about their current employees than about outside prospective ones, we utilize changes to non-competition agreement law, which determine the viability of hiring external employees, to assess the existence of gender discrimination in top management positions. We find results consistent with information based discrimination theory.São apontadas diversas causas para o fenómeno da discriminação, consistindo uma delas na informação disponível. Tal teoria defende que a falta de informação específica sobre indivíduos conduz a julgamentos com base nas características (potencialmente enviesadas) que se imputam aos grupos a que pertencem. Explorando o facto de as empresas terem informação mais exata sobre os trabalhadores ao seu serviço do que sobre os que potencialmente podem contratar, usámos alterações a leis dos EUA sobre os acordos de não concorrência (que determinam a viabilidade de contratar trabalhadores no mercado) para avaliar a existência de discriminação de género em lugares de gestão de primeira linha. Chegámos a resultados consistentes com a teoria da discriminação baseada na informação disponível

The impact of cultural time perception in economic behavior: A reinforcement of Max Weber's thesis

The individual and collective perception of time, which is culturally transmitted, molds significantly the way individuals and societies behave and perform in economic matters. The overall aim is to explore how time (as a resource and an institution) is thought-out and how it is one of the most preponderant factors to influence, for instance, consumption, preferences, economic growth and development. The investigation aims to further corroborate and strengthen Max Weber’s 1904-1905 The Protestant Ethic and the Spirit of Capitalism. This is done by showing that the perception of time comes forward as an important cause of the differences between the ascetic Protestant and Catholic mentalities, and consequently their economic behavior and decision-making processes. In other words, it aims to prove that cultural time is a variable (albeit often neglected) that plays a central role in the way the “capitalistic spirit” appeared among certain Protestant doctrines and helped construct the economic paradigms of our times.A perceção individual e coletiva de tempo, que é transmitida por via cultural, molda consideravelmente a forma como os indivíduos e as sociedades agem e como é o seu desempenho em termos económicos. O principal objetivo da presente tese é abordar a forma como o tempo (como um recurso e uma instituição) está presente como um dos fatores que mais influência tem sobre o consumo, as preferências, o crescimento económico e o desenvolvimento. Pretende-se, nesse sentido, corroborar e consolidar a obra A Ética Protestante e o Espírito do Capitalismo de Max Weber (1904-1905). Tal faz-se ao demonstrar que a perceção de tempo assume um papel central no contraste entre as formas de pensamento e conceções protestantes e católicas, e consequentemente o seu comportamento económico e processos de tomada de decisão. Por outras palavras, pretende-se provar que o tempo cultural é uma variável (ainda que frequentemente negligenciada) que assume um papel central na forma como o “espírito capitalista” surgiu em determinadas doutrinas protestantes e ajudou a construir os paradigmas económicos dos nossos tempos

Ovarian Cancer Overview: Molecular Biology and Its Potential Clinical Application

Over the previous two decades, there has been a shift in the ovarian cancer paradigm to consider it as a multiplicity of disease types rather than a single disease, requiring specialized medical management from molecular diagnosis through to treatment. Despite the achieved improvements in diagnosis, surgery, and systemic treatment, ovarian cancer remains the leading cause of death from gynecological tumors in western countries. The study of ovarian cancer at a molecular level could reveal potential biomarkers of disease diagnosis and progression, as well as possible therapeutic targets in areas such as angiogenesis and homologous recombination deficiencies. Although this area of research is proving invaluable concerning newer therapeutic approaches, platinum-based chemotherapy continues to be the core of the first-line treatment. Genomic screening focusing on the identification of prognostic and predictive markers is considered one of the leading areas for future ovarian cancer research

Applicability of the current stock assessment models to the priority azorean fishery resources

This work presents a guidance to conduct stock assessment based on ICES Maximum Sustainable Yield framework. A cross-analysis based on the models’ assumptions and inputs and data available for 22 Azorean priority stocks was performed to assess the applicability of each model to each stock. Information currently available for coastal and some demersal/deep-water stocks limits the use of most models validated by ICES. Only four demersal/deep-water stocks (Pagellus bogaraveo, Helicolenus dactylopterus, Phycis phycis, and Pontinus kuhlii) have data availability and quality enough to perform trend analysis, length-based and catch and survey-based methods. The next steps involve validating life-history parameters, evaluating model performances, and applying alternative tools for data-deficient stocks. Additional monitoring programs are of utmost importance, which must collect missing information and clarify stock delimitation to improve assessment quality. This study guides future stock assessment actions and highlights data gaps where future research should focus.This study is part of the PESCAz project (ref. MAR-01.03.02-FEAMP-0039) financed by the European Maritime and Fisheries Fund (EMFF) through the Regional Government of the Azores under the MAR2020 operational program.info:eu-repo/semantics/publishedVersio

Methodology for single nucleotide polymorphism selection in promoter regions for clinical use. An example of its applicability

Genetic variability in humans can explain many differences in disease risk factors. Polymorphism-related studies focus mainly on the single nucleotide polymorphisms (SNPs) of coding regions of the genes. SNPs on DNA binding motifs of the promoter region have been less explored. On a recent study of SNPs in patients with non-Hodgkin lymphomas we faced the problem of SNP selection from promoter regions and developed a practical methodology for clinical studies. The process consists in identifying SNPs in the coding and promoter regions of the antigen-processing system using the 'dbSNP' database. With the 'HapMap' program, we select SNPs with frequencies >20% in Caucasian populations. For coding regions, we sought biologically and clinically relevant SNPs described in the literature. For the promoter regions, we determined their chromosomal location on 'QiagenSABioscience' site database. The nucleotide sequence of ancestral and variant alleles is available in the 'dbSNP'. These sequences were used in ` Promoter TESS' to determine binding differences of transcription factors. Each sequence may have affinity to different TFs. Thus, SNP selection on the promoter regions was based in the differences on TF binding pattern between the old and the new allele. The potential clinical relevance of the new TFs was also evaluated before the final selection. With this approach, we found that almost half of the relevant SNP fall within the promoter region. In conclusion, we were able to develop a methodology of oriented selection of promoter regions of human genes, comparing the TF with affinity to the ancestral allele with the TF to a variant allele. We selected those SNPs that change the TF's affinity to a pattern with functional significance.(undefined)info:eu-repo/semantics/publishedVersio
