User-generated content strategy & millennials’ travel intentions
Instagram has created new exciting ways for millennials to connect, interact and contribute to a
pool of online content by taking on the role of content creators. Hence, millennials’ experiences
are being shaped by information obtained and created online in the form of User-Generated
Content (UGC). However, recent tactics to integrate UGC within brands’ content strategies
raised questions about the effects of ‘pure’ UGC compared to other UGC tactics (e.g. paid
partnership or sponsored content).
The main goal of the study was to understand how exposure to different User-Generated Content
Strategies influence millennials’ decisions in the context of Instagram and Travel. In order to
achieve these goals, a cross-sectional online survey with a built-in experiment was conducted.
Findings from the quantitative data analysis indicated that travel-related UGC created on
Instagram shapes every stage of Millennials’ Travel Journeys. In addition, results showed
significant differences in the degree of Millennials’ Online Engagement, Perceived
Trustworthiness, and Travel Intentions, when exposed to different strategies of UGC. Moreover,
UGC created by an independent Instagram user showed the most significant results in terms of
Engagement. However, when it came to Trustworthiness, UGC #reposted on a Brand Official
Account turned out to be the best strategy to gain Millennials’ Trust.
This study further emphasizes the valuable potential of UGC for businesses and contributes to
relevant insights and practical recommendations on how marketers can take advantage of UGC
as a marketing tool and develop an effective UGC Strategy to target Millennials.O Instagram criou novas formas para a geração Millennial interagir e contribuir com conteúdo
online, ao tomarem a posição de criadores de conteúdo. Consequentemente, as experiências desta
geração estão a ser influenciadas por informação obtida e criada online na forma de usergenerated-
content (UGC). No entanto, recentes táticas para integrar UGC nas estratégias das
marcas levantaram questões no que diz respeito ao efeito de ‘puro’ UGC comparado com outras
tácticas de UGC (ex. parcerias pagas ou conteúdo patrocinado).
O presente estudo tem como principal propósito compreender o impacto de diferentes estratégias
de User-Generated Content nos Millennials, no contexto do Instagram e Viagens. Para tal, um
questionário transversal foi realizado.
Os resultados obtidos indicam que UGC, relacionado com viagens partilhado no Instagram, está
presente em todas as etapas da experiência dos Millennials. Para além disso, os resultados
estatísticos indicam diferenças significativas no que diz respeito ao nível de envolvimento
online, percepção de confiança do conteúdo, e intenções de viajar, quando expostos a diferentes
estratégias de UGC. A estratégia que demonstrou resultados mais significativos, em termos de
envolvimento online, foi o cenário em que estava presente conteúdo publicado por um
Instagrammer na sua própria conta. No entanto, relativamente à percepção de confiança, o
conteúdo re-partilhado na conta oficial da marca indica ser a melhor estratégia para ganhar a
confiança desta geração.
Este estudo reforça o valor de UGC para as marcas e contribui ainda com informação relevante,
propondo recomendações práticas sobre como desenvolver uma estratégia de UGC eficaz para
influenciar Millennials
A symbolic homecoming: 3D digital imaging of Greek vases from the MHNC-UP
One of the most interesting Portuguese-German diplomatic
relations is associated with the imprisonment of a ship in Lisbon during World War
I. Bringing this centenary story, which took place between 1914 and 1927, back to
light seemed appropriate due to its strong symbolic charge: some of the pieces
contemplated in the events we will soon be remembering are symbolically returning
home. The subject is not new, however, as it has already been the subject of a
number of publications, including by one of the proponents of this study. But the
approach presented here is naturally different, as it falls within one of the themes
under discussion at this meeting, 3D digital analysis methods and techniques. This
approach has already been considered several times by another of the proponents
of this study, one of which included four Greek vases from different productions
and periods from the Museum of Natural History and Science of the University of
Porto (MHNC-UP) that we will be discussing
Understanding Virtual Objects through Reverse Engineering
[EN] The main objective of our research is to develop a new methodology, based on Reverse Engineering processes – 3D scan, quantitative data analysis and Artificial Intelligence techniques, in particular simulation – to study the relationship between form and function of artefacts. Furthermore, we aim to provide new data, as well as possible explanations of the archaeological record according to what it expects about social activity, including working processes, by simulating the potentialities of such actions in terms of input-output relationships.[ES] El principal objetivo de nuestra investigación consiste en desarrollar una nueva metodología de análisis e interpretación de artefactos arqueológicos para el estudio de la relación entre forma y función de los artefactos. El fundamento de nuestra propuesta es un enfoque basado en técnicas de Ingeniería Inversa que partiendo de datos visuales procedentes de escaneo 3D, los pone en relación con las consecuencias esperadas de las acciones sociales que tuvieron lugar en el pasado en un enfoque de Inteligencia Artificial y análisis cuantitativo de datos. Además, nuestro trabajo está basado en la nueva manera de “ver” la realidad arqueológica. El procedimiento consiste en la “simulación” computacional de la cinemática de esas acciones y ele estudio de las características geométricas y visuales de sus consecuencias potenciales, expresando los resultados en términos de relaciones entrada-salida.This research is funded by the Spanish Ministry for Scienc and Innovation, under grant No. HAR2009-12258, and it is a part of the joint

Three-dimensional reconstruction of Roman coins from photometric image sets
A method is presented for increasing the spatial resolution of the three-dimensional (3-D) digital representation of coins by combining fine photometric detail derived from a set of photographic images with accurate geometric data from a 3-D laser scanner. 3-D reconstructions were made of the obverse and reverse sides of two ancient Roman denarii by processing sets of images captured under directional lighting in an illumination dome. Surface normal vectors were calculated by a “bounded regression” technique, excluding both shadow and specular components of reflection from the metallic surface. Because of the known difficulty in achieving geometric accuracy when integrating photometric normals to produce a digital elevation model, the low spatial frequencies were replaced by those derived from the point cloud produced by a 3-D laser scanner. The two datasets were scaled and registered by matching the outlines and correlating the surface gradients. The final result was a realistic rendering of the coins at a spatial resolution of 75 pixels/mm (13-μm spacing), in which the fine detail modulated the underlying geometric form of the surface relief. The method opens the way to obtain high quality 3-D representations of coins in collections to enable interactive online viewing

Revisão da abordagem da acromegália : a propósito de um caso clínico
Trabalho Final do Curso de Mestrado Integrado em Medicina, Faculdade de Medicina, Universidade de Lisboa, 2019A acromegália é uma doença que representa um desafio diagnóstico, tanto pela sua raridade como pelo facto da sua apresentação clínica ser insidiosa e multissistémica. A sua morbilidade e mortalidade é significativa, tendo sido descrita uma esperança de vida inferior em 10 anos à da população saudável. Por esta razão uma correta abordagem destes doentes e acompanhamento em centros diferenciados é fundamental. Sendo a cirurgia a única terapêutica com potencial curativo, é, sem dúvida, a primeira linha de tratamento. Nos últimos anos surgiram novas alternativas terapêuticas que demonstraram elevada eficácia no controlo da doença em casos em que a cirurgia não tenha sido bem sucedida ou não possa ser realizada. Também o aparecimento de novos marcadores de resposta à terapêutica imagiológicos, histológicos e genéticos são fatores que devem ser integrados na abordagem inicial destes doentes de forma a poder ser realizada a melhor terapêutica caso-a-caso. Assim, salienta-se a necessidade de uma abordagem individualizada da doença em que as características do doente são os pilares da decisão terapêutica e da monitorização da doença.Acromegaly is a disease that represents a diagnostical challenge, not only for its rareness but also because of its slow onset of symptoms and its multisystemic characteristics. The morbility and mortality in these patients is significant, with a life expectancy 10 years inferior to that of the healthy population. For this reason, it is crucial to follow a correct approach across specialized instituitions. Surgery is the only treatment with curative potential and is, therefore, the first line of treatment. In the past years new treatment alternatives have emerged, demonstrating excellent results in controlling the disease in patients with persistent disease after surgery or when surgery is unavailable. New radiological, histologic and genetic markers of response to treatment have also been studied and should be integrated in the initial approach of these patients as an important factor in the decision of the best treatment option in each case. It is important to emphasize the need of an individual approach of acromegaly where the patients’ characteristics are the pillars of the treatment’s decision and follow-up of the disease
Práticas turísticas e comunidades cristãs : para uma criteriologia teológico-prática
O turismo é claramente uma prática em crescimento em Portugal. Como cristãos
somos chamados a Evangelizar nas nossa realidade atual e, perante o crescimento turístico, a
ação pastoral não pode esquecer esta dimensão humana que deriva do seu ser peregrino.
A reflexão realizada neste trabalho pretende através da sinalização de pontos de
ligação, entre o turismo e a evangelização, levar o turista a regressar à sua «origem» (ser
peregrino). Para se conseguir verdadeiramente evangelizar neste campo de ação, é
indispensável a comunidade paroquial, a qual através de gestos de hospitalidade, num
contexto de intimidade e partilha, se torna a ponte para o encontro com Deus da pessoa que
provavelmente apenas está a visitar cultura.Clearly tourism is a growing practise in Portugal. As christians we are called to
Evangelise in our reality and, towards the growth of tourism, the pastoral action can't forget
this human dimension that drifts from being peregrine.
The reflection carried out in this work intends to point out links between tourism and
evangelization, to bring tourists back to their "origin" (being a pilgrim). In order to truly
evangelize in this field of action, the parish community is indispensable, which through
gestures of hospitality, in a context of intimacy and sharing, becomes the bridge to the
encounter with God of the person who probably isjust visiting culture
