Filicídio: razões que levam os pais a matarem os seus filhos

Projeto de Graduação apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de licenciada em CriminologiaA morte dos filhos à mão dos seus pais, é uma ato de difícil compreensão, uma vez que o porto seguro das crianças em primeiro lugar deveriam ser os seus pais. No entanto, são vários os casos acontecidos deste a antiguidade até aos dias de hoje. No presente projeto, o filicídio foi o tema dominante, como tal o objetivo baseou-se na tentativa de compreender as motivações dos pais tirarem a vida a um ser que nasceu dos mesmos. Procedeu-se à análise dos diferentes tipos de filicídio, bem como as carateristicas dos ofensores e das vítimas assim como os métodos mais utilizados para o assassinato das crianças, verificando-se que há uma diferença destes no género dos homicidas. Por fim, analisaram-se estudos de diferentes autores, onde se pode comparar entre o ano de 1961 e 2011, no Canadá, as principais motivações para a prática do crime ao longo destes períodos.The death of the children to the hand of their parents, is an difficult act to understand, since the safe haven of the children should be their parents first. However, there are several cases that happened from past times until the present day. In this project, filicide was the dominant theme as such order was based on the attempt to understand the motivations of parents take the life of a being born of the same. We proceeded to the analysis of different types of filicide as well as the features of offenders and victims as well, as the methods used for the murdering of children, verifying that there is a difference in these kind of homicidal. Finally, we analyzed studies of different authors, where we can compare, between 1961 and 2011, in Canada, the main motivations for the crime

Ensino/aprendizagem num novo contexto tecnológico: um estudo no âmbito do ensino superior

Today’s students of higher education are considered digital natives. They have a wide array of technologies at their disposal that are used in their day-to-day lives in very different contexts; including recreation, work and academic. This scenario promotes a change of culture by the main actors associated with the Teaching/Learning process. This prompted the development of the present thesis which aims to evaluate the degree of use and acceptance of technologies supporting the Teaching/Learning process in Higher Education Institutions (HEI). The methodology used when conducting this study was based initially on a review of the specialized literature, identifying the three main technological generations supporting the Teaching/Learning process: Learning Management Systems (LMS), Web 2.0 technologies and Massive Open Online Courses (MOOCs). Subsequently, the technologies recognized as the most relevant within each of these generations have been the subject of (i) a systematic literature review, (ii) a content analysis elaborated on the platforms/technologies used in international Higher Education Institutions, and (iii) an empirical work conducted at a Portuguese Higher Education Institution. Concerning the latter, an understanding of the behavior of the two main players involved in the Teaching/Learning process (students and teachers) was particularly sought after. Therefore, studies were conducted on (i) the students’ use of the main technologies, (ii) the students’ acceptance of some of these technologies in the context of Teaching/Learning and (iii) the use and acceptance of the technologies by teachers. The results indicated that the Moodle platform is the LMS most used in Higher Education Institutions. In this context, the platform is mostly used as a content repository and a communication channel. As for Web 2.0, Video Sharing, Social Networks and Wikis were proven to be the technologies most used by students and teachers. The results also revealed that the technologies in question are well accepted by both parties, thus showing that their adoption could benefit the Teaching/Learning process in the new technological paradigm. Regarding the MOOCs, few teachers showed knowledge of the concept and no teachers who had created these type of courses were identified. This study resulted in the development of seven scientific works with peer review, being five scientific papers published or submitted to international scientific journals and two chapters published in international books. These scientific works constitute an integral part of this doctoral thesis.Atualmente, os estudantes do ensino superior são considerados nativos digitais, tendo à sua disposição um conjunto abrangente de tecnologias que utilizam no seu dia a dia nos mais diversos contextos, incluindo o de lazer, de trabalho e académico. Este cenário promove uma mudança de cultura por parte dos principais atores associados ao processo de Ensino/Aprendizagem, o que motivou o desenvolvimento da presente tese que tem por objetivo avaliar o grau de utilização e de aceitação das tecnologias de suporte ao processo Ensino/Aprendizagem nas Instituições de Ensino Superior (IES). A metodologia utilizada na condução deste estudo, baseou-se inicialmente numa revisão da literatura especializada, tendo-se identificado as três principais gerações tecnológicas de suporte ao processo Ensino/Aprendizagem, mais especificamente os Learning Management Systems (LSM), as tecnologias Web 2.0 e os Massive Open Online Courses (MOOCs). Seguidamente, as tecnologias reconhecidas como as mais relevantes no âmbito de cada uma destas gerações foram alvo de revisão sistemática da literatura, de análise de conteúdo elaborada sobre as plataformas/tecnologias utilizadas em Instituições de Ensino Superior de referência a nível internacional, e de trabalhos empíricos conduzidos numa Instituição de Ensino Superior Portuguesa. Em particular, no que se refere a estes últimos, procurou-se perceber o comportamento relativo à adoção das tecnologias por parte dos dois principais intervenientes no processo Ensino/Aprendizagem, i.e., estudantes e professores. Desta forma, foram conduzidos estudos acerca (i) da utilização, por parte dos estudantes, das principais tecnologias, (ii) da aceitação, por parte dos estudantes, de algumas dessas tecnologias em contexto Ensino/Aprendizagem e (iii) da utilização e aceitação das tecnologias por parte dos professores. Os resultados apontaram para o facto de a plataforma Moodle representar o LMS mais utilizado no Ensino Superior sendo, no contexto do caso analisado, utilizado maioritariamente como repositório de conteúdos e canal de comunicação. No que se refere à Web 2.0, o Video Sharing, as Redes Sociais e as Wikis revelaram-se como as tecnologias mais utilizadas pelos estudantes e pelos professores. Os resultados revelaram, ainda, que as tecnologias em causa são bem aceites, tanto por parte dos estudantes como dos professores, evidenciando, assim, que a sua adoção poderá beneficiar o processo Ensino/Aprendizagem no paradigma tecnológico. Já no que diz respeito às MOOCs, poucos professores evidenciaram conhecer o conceito, não se tendo identificado professores que tivessem criado este tipo de cursos. Este estudo traduziu-se na elaboração de sete trabalhos científicos com revisão por pares, dos quais cinco artigos publicados/submetidos a revistas científicas internacionais e dois capítulos publicados de livros internacionais, que aqui se apresentam e constituem parte integrante desta tese de doutoramento.Programa Doutoral em Engenharia e Gestão Industria

Investigation of laser based processes to optimize eletrospun nanofiber nonwovens for tissue engineering

Polymers and especially polymeric nanofibers are widely investigated in tissue engineering. These materials can imitate the extracellular matrix. Therefore, they can be used as scaffolds for growing human cells. However, in many cases a surface treatment of the nanofiber nonwovens is useful to enhance the cell adhesion. The polar and dispersion components of surface free energy have to be adjusted to control the wettability. To optimize the cell colonization on electrospun nanofibers, polyamide (PA 6.6) and polylactide (PLA) fibers were processed with different types of pulsed UV laser radiation. For comparison polyimide (PI), PA and PLA bulk materials were also investigated. Static contact angles were measured before and after laser processing to investigate the effects of laser irradiation on the wettability. The morphology of the treated areas was evaluated by confocal and scanning electron microscopy. Chemical analyses, like FTIR-ATR were also performed. The wettability of the different materials was changed. PA nanofiber nonwovens are hydrophilic and are appropriate for good adhesion of some kind of cells. PLA nanofiber nonwovens are hydrophobic. By certain laser processes, it was also possible to make this material more hydrophilic. It was observed, that the laser generated topography of the nonwovens plays a great rule in the wettability

Experiences over possessions: Millennials and the experience economy

Nowadays, consumers all over the world are opting for having leisure experiences over owning material possessions. One group in particular is said to be primarily responsible for driving this consumer shift - the millennial generation. As millennials become the generation with the highest global spending power and global expenditure on the experience economy continues to rise, it is pressing to comprehend the dynamic of this environment. Hence, the objective of this dissertation is to better understand the relation between the millennial generation and the experience economy and, more precisely, this cohort’s preference for experiences over possessions and the role played by the experiential categories themselves (entertainment, educational, escapist and esthetic). As such, to discover which experiential realms and elements are more valuable to millennials and the deeper personal outcomes they desire from each experience type, a questionnaire was devised to assess their behaviors and beliefs on this matter. The collected data was analyzed through descriptive statistics. Findings show that millennials exhibit a strong overall preference for experiential purchases over material ones. Yet, esthetic experiences are deemed less relevant than clothes and accessories or even electronic devices, which suggests that not all types of leisure experiences are preferred to material possessions. Additionally, it became evident that millennials desire experiences that correspond to their distinct emotional expectations and that are experientially diverse.Hoje em dia, consumidores de todo o mundo estão a optar por experiências de lazer sobre a posse de bens materiais. Um grupo em particular é considerado como o principal responsável por impulsionar esta mudança de consumo - a geração millennial. À medida que os millennials se tornam a geração com maior poder de compra e o gasto global na economia da experiência continua a aumentar, torna-se premente entender a dinâmica deste ambiente. Assim, o objetivo desta dissertação é compreender melhor a relação entre a geração millennial e a economia da experiência e, mais precisamente, a preferência deste grupo por experiências sobre posses e o papel desempenhado pelas próprias categorias experienciais (entretenimento, educação, escape e estética). Como tal, para descobrir quais os tipos e elementos experienciais mais valiosos para os millennials e os resultados particulares que desejam de cada categoria de experiência, foi concebido um questionário para avaliar os seus comportamentos e atitudes neste tema. Os dados recolhidos foram analisados através de estatísticas descritivas. Os resultados mostram que os millennials apresentam uma forte preferência geral por compras experienciais em relação às materiais. No entanto, as experiências estéticas são consideradas menos relevantes que roupas e acessórios ou mesmo dispositivos eletrónicos, o que sugere que nem todos os tipos de experiências de lazer são preferíveis a bens materiais. Para além disso, tornou-se evidente que os millennials desejam experiências que correspondam às suas distintas expectativas emocionais e que sejam experiencialmente diversas

Development of a Osirix plug-in for non-gaussian diffusion MRI data: application to Breast

Breast cancer is the second leading cause of death by cancer and is the second type of cancer that is the most common among women, causing the death of 1500 women, every year, in Portugal. Over the past decades, with the improvement of imaging techniques and therapeutics, breast cancer mortality rate has been decreasing substantially. One of the imaging techniques used is diffusion-weighted imaging (DWI), which is the magnetic resonance imaging method that is the most sensitive in detecting invasive breast cancer. There are several extensions of this technique that can be based on the premise that the environment is not homogeneous (non-Gaussian models). The non-Gaussian models, take into account the presence of barriers and compartments that restrict the water molecules movement in the biological tissues, allowing the distinction between malignant and benign lesions in DWI. Taking into account that diffusion-weighted imaging is a non invasive method, the diagnosis through the application of these models can become an alternative to biopsy. The main goal of this dissertation was the development of a OsiriX plug-in that performs the non-Gaussian diffusion analysis of DWI in magnetic resonance imaging data. Five non-Gaussian diffusion models were implemented in the application: diffusion kurtosis imaging, intravoxel incoherent motion, gamma distribution, truncated and stretched-exponential. Parametric maps and region-of interest (ROI) parametric values were obtained for each model. In order to fit the various non-Gaussian diffusion models, the Levenberg-Marquardt algorithm was used. This algorithm finds coefficients x to best fit the nonlinear function to the data. The x coefficients results in parametric maps that are able to identify the tumour and also distinguish between malignant and benign lesions provided a comparison with the literature. During the application development, these functionalities were also used to study the dependence of fitted parameters on the number of b-values used and on the image noise. An interface was developed with Objective-C on Xcode for OsiriX where the user gets to choose from five diffusion models in order to obtain parameric maps or values. It also informs on the goodness of fit and it provides fitting plots of the data. The references of the models and extra information are also available in an help button. Finally, the application was tested successfully with breast DWI images of benign and malignant tumors
