Factores de vulnerabilidade para a agressão sexual

A violência sexual contra mulheres e crianças é um fenómeno social e de saúde pública, transversal a diferentes culturas e épocas históricas. A consciencialização deste fenómeno ocorre porém num milénio em que a auto-determinação das mulheres e os direitos fundamentais das crianças passaram a ser considerados pelas principais estâncias políticas. Paralelamente, também a ciência tem dado o seu contributo para a compreensão e resolução destes crimes. Os estudos acerca dos mecanismos de predisposição para a agressão sexual visam a reabilitação dos indivíduos que cometeram ofensas sexuais, prevenindo a reincidência destes comportamentos. O objectivo é diminuir o número de vítimas, intervindo no agressor. O trabalho que apresentamos teve por finalidade investigar potenciais factores de predisposição para a agressão sexual em sujeitos do sexo masculino condenados por crime de violação e abuso sexual de menores, mas também em estudantes universitários com história de violência sexual. Pretendeu-se avaliar de que forma os esquemas precoces mal adaptativos, os mecanismos de inibição/excitação sexual e a personalidade intervêm nestas diferentes formas de violência sexual. Os resultados deste trabalho indicaram que as dimensões avaliadas poderão contribuir para a predisposição e/ou manutenção dos comportamentos de agressão sexual. Adicionalmente, verificou-se que as diferentes formas de violência sexual (violação, abuso sexual de menores e violência sexual em estudantes universitários) são caracterizadas por perfis distintos, e que esta especificidade poderá ser determinante na elaboração de modelos de conceptualização da agressão sexual.

Antecedents of loyalty to a brand : Apple clients vs. non-clients

Apple is undoubtedly a sui generis and remarkable brand in what concerns to its branding and brand experience, and remains an indisputable reference in the consumer electronics and computer industries. The aim of this study encompasses the development and empirical testing of two conceptual models that evaluate and allow to draw a comparison between Apple clients and non-clients’ perceptions, regarding brand experience, brand perceived value, price perceptions and brand trust; and that determine the antecedents of clients’ loyalty to the brand. Therefore, the contribution of this study to the literature relies on the research of the impact of brand experience on brand perceived value and on price perceptions, as well as the influence of price perceptions (positive and negative) on trust, satisfaction, and commitment to the brand. Two surveys were used to test each conceptual model, through a sample collected across the portuguese academic community. The findings prove the strong influence of the sensory and affective aspects of brand experience on both clients and non-clients. They also reveal that the negative role of price is neutralized in the presence of strong brand experience, and that the fact that Apple is viewed as an “expensive brand” may highlight its association to higher quality and prestige. Also, this study reinforces the important role of satisfaction and commitment in building customer loyalty, corroborating the existent literature. Managerial implications derived from the findings are also discussed.

Integrated coastal geoengineering approach for maritime environments

This dissertation introduces several methodological approaches which integrate a proposed coastal management model in an interdisciplinary perspective. The research presented herein is displayed as a set of publications comprising different thematic outlooks. The thesis develops an integrated coastal geoengineering approach which is intrinsically linked to the studied maritime environments. From sandy coasts and marine works to rocky platforms and sea cliffs, this study includes field work between Caminha – Figueira da Foz (NW Portugal) and Galicia (NW Spain). The research also involves an analysis and geological-geotechnical characterisation of natural rock (armourstone) and artificial units (concrete blocks) applied to coastal structures. The main goal is to contribute to the characterisation and re-evaluation of georesources and to determine armourstone suitability and availability from its source (quarry). It was also important to diagnose the geomaterials in situ concerning their degradation/deterioration level on the basis of the current status of the coastal protection works in order to facilitate more efficient monitoring and maintenance, with economic benefits. In the rocky coast approach the coastal blocks were studied along the platform, but also the geoforms were studied from a coastal morphodynamics point of view. A shoreline evolution analysis was developed for sandy coasts through Digital Shoreline Analysis System (DSAS) extension. In addition, the spatial and statistical analysis applied to sea cliffs allowed the establishment of susceptibility zones to erosion and hazardous areas. All of these studies have different purposes and results however, there is a common denominator – GIS mapping. Hence, apart from the studied coastal environment, there is an integrated system which includes a sequence of procedures and methodologies that persisted during the research period. This is a step forward in the study of different coastal environments by using almost the same methodologies. This will allow the characterisation, monitoring and assessment of coastal protection works, rocky coasts, and shore platforms. With such data, it is possible to propose or recommend strategies for coastal and shoreline management based on several justifications in terms of social, economic, and environmental questions, or even provide a GIS-based planning support system reinforced by geocartographic decisions. Overall the development of the applied cartography embraces six stages which will allow the production of detailed maps of the maritime environment: (1) high-resolution aerial imagery surveys; (2) visual inspection and systematic monitoring; (3) applied field datasheet; (4) in situ evaluation; (5) scanline surveying; and (6) GIS mapping. This thesis covers fundamental matters that were developed over the course of scientific publication and as a consequence they represent the results obtained and discussed. The subjects directly related to the thesis architecture are: (i) cartography applied to coastal dynamics (including an art historical analysis as a tool to comprehend the coastal evolution and the littoral zone); (ii) georesources assessment (the role of cartography in georesources zoning, assessment and armourstone durability); (iii) coastal geoengineering applications and monitoring (Espinho pilot site in NW Portugal as an experimental field); (iv) rocky coast and shore platform studies and characterisation; (v) sandy and mixed environment approaches; (vi) coastal geosciences GIS mapping and photogrammetric surveying (coastal geoengineering); and (vii) shoreline change mapping and coastal management strategies (the CartGalicia Project as an example – NW Spain). Finally, all of these thematic areas were crucial to generate the conceptual models proposed and to shape the future of integrated coastal coastal geoengineering management.

Impacto dos estímulos sensoriais na experiência e no valor da marca

O marketing sensorial é uma estratégia de comunicação recente que permite diferenciar uma empresa das suas concorrentes, através da estimulação dos 5 sentidos humanos. A literatura permite formular dois modelos concetuais (clientes e conhecedores) com o objetivo de compreender qual a influência que os estímulos sensoriais têm nos consequentes, como a experiência e os valores de marca, e as consequências dessas relações. A validação dos modelos de investigação realizou-se com base num estudo empírico, que considerou uma marca Aveirense bem implantada no mercado, a Pizzarte Os resultados obtidos mostram que a estimulação sensorial influencia positivamente a experiência e o valor da marca, repercutindo-se na atitude positiva e na intenção de compra da marca.
