Computer analysis of face beauty: a survey
The human face conveys to other human beings, and potentially to computer systems, information such as identity, intentions, emotional and health states, attractiveness, age, gender and ethnicity. In most cases analyzing this information involves the computer science as well as the human and medical sciences. The most studied multidisciplinary problems are analyzing emotions, estimating age and modeling aging effects. An emerging area is the analysis of human attractiveness. The purpose of this paper is to survey recent research on the computer analysis of human beauty. First we present results in human sciences and medicine pointing to a largely shared and data-driven perception of attractiveness, which is a rationale of computer beauty analysis. After discussing practical application areas, we survey current studies on the automatic analysis of facial attractiveness aimed at: i) relating attractiveness to particular facial features; ii) assessing attractiveness automatically; iii) improving the attractiveness of 2D or 3D face images. Finally we discuss open problems and possible lines of research
Subjectivity and complexity of facial attractiveness
The origin and meaning of facial beauty represent a longstanding puzzle.
Despite the profuse literature devoted to facial attractiveness, its very
nature, its determinants and the nature of inter-person differences remain
controversial issues. Here we tackle such questions proposing a novel
experimental approach in which human subjects, instead of rating natural faces,
are allowed to efficiently explore the face-space and 'sculpt' their favorite
variation of a reference facial image. The results reveal that different
subjects prefer distinguishable regions of the face-space, highlighting the
essential subjectivity of the phenomenon.The different sculpted facial vectors
exhibit strong correlations among pairs of facial distances, characterising the
underlying universality and complexity of the cognitive processes, and the
relative relevance and robustness of the different facial distances.Comment: 15 pages, 5 figures. Supplementary information: 26 pages, 13 figure
Understanding and modeling of aesthetic response to shape and color in car body design
This study explored the phenomenon that a consumer's preference on color of car body may vary depending on shape of the car body. First, the study attempted to establish a theoretical framework that can account for this phenomenon. This framework is based on the (modern-) Darwinism approach to the so-called evolutionary psychology and aesthetics. It assumes that human's aesthetic sense works like an agent that seeks for environmental patterns that potentially afford to benefit the underlying needs of the agent, and this seeking process is evolutionary fitting. Second, by adopting the framework, a pattern called “fundamental aesthetic dimensions” was developed for identifying and modeling consumer’s aesthetic response to car body shape and color. Next, this study developed an effective tool that is capable in capturing and accommodating consumer’s color preference on a given car body shape. This tool was implemented by incorporating classic color theories and advanced digital technologies; it was named “Color-Shape Synthesizer”. Finally, an experiment was conducted to verify some of the theoretical developments.
This study concluded (1) the fundamental aesthetics dimensions can be used for describing aesthetics in terms of shape and color; (2) the Color-Shape Synthesizer tool can be well applied in practicing car body designs; and (3) mapping between semantic representations of aesthetic response to the fundamental aesthetics dimensions can likely be a multiple-network structure
Consumer behaviour in wine tourism: involvement, destination emotions and place attachment in the wine tourist behaviour during the Porto wine cellars visits context
Tese apresentada à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Doutor em Ciências EmpresariaisThis study aims to contribute to the conceptual development of consumer behaviour in
wine tourism area by bringing new discussion and empirical evidences. For this, a
literature review of the main concepts was conducted in order to develop and support a
conceptual model. This model was subsequently validated and empirically tested, and a
hypothetical relationship between constructs was established: involvement (personal
involvement and wine product involvement), destination emotions and place attachment
(place identity and place dependence). This is, so far, the first study that analyses the
combined interaction of all these constructs. This research was undertaken in the
framework of wine tourism, namely the measurement of the wine tourist behavior after
visiting the Porto wine cellars.
Methodologically, the first chapter is a qualitative exploratory study that performed a
content analysis on the key constructs (involvement and emotions), allowing a better
understanding of how they can be defined, and the main dimensions underlying each
one of them. The second chapter consisted of a conceptual approach, which focused on
the clarification of the definition of wine tourism, and the wine tourist behaviour in
particular. It also explored the possible relations between constructs (involvement,
destination emotions, place attachment and behavioural intentions), postulating the key preposition that stems from their interaction. In the third chapter, a quantitative research
was used, using a personal intercept survey in the Porto wine cellars to validate and to
give empirical evidences about the behaviour of the Porto wine cellar visitor. The
multilevel analysis of the proposed structural model was made using the SmartPLS
software, allowing the confirmation of all the proposed hypotheses.
In the first chapter, the findings provided a theoretical support of the relevance of
involvement and emotions constructs in the field of tourism. The content analysis
produced insights based on concepts and definitions of these two constructs on a more
holistic perspective. In the second chapter, the findings sustain the special interest in
consumer behaviour in wine tourism, and it stated a set of five prepositions, where the
main constructs are interlinked. In the third chapter, the empirical results indicated that
wine tourists’ personal involvement and their wine product involvement have a
significant influence (and a direct effect) on destination emotions and place attachment,
driving their behavioural intentions.
The study had direct implications (analysis and evaluation of the wine tourist travel
behaviour and wine tourist profile) for the Porto wine cellars. The results led to practical
implications and suggestions for wine tourism managers. Este estudo tem como propĂłsito contribuir para o desenvolvimento conceptual do
comportamento do consumidor na área do enoturismo, contribuindo com uma nova
discussĂŁo e evidĂŞncias empĂricas. Foi realizada uma revisĂŁo da literatura sobre os
principais construtos, a fim de desenvolver e apoiar um modelo conceptual. Este modelo
foi posteriormente validado e testado empiricamente, e foi estabelecida uma relação
hipotética entre os construtos: envolvimento (envolvimento pessoal e envolvimento com
o produto vinho), as emoções do destino e apego ao lugar (identidade do lugar e
dependência do lugar). Até agora, este é o primeiro estudo que analisa a interação
combinada de todos estes construtos. Esta pesquisa foi realizada no âmbito do
enoturismo, ou seja, a medição do comportamento do enoturista após visitar as caves do
vinho do Porto.
Relativamente Ă metodologia aplicada, o primeiro capĂtulo Ă© um estudo qualitativo
exploratório que resultou numa análise de conteúdo sobre os construtos chave
(envolvimento e emoções), permitindo uma melhor compreensão de como eles podem
ser definidos, e as principais dimensões subjacentes a cada um deles. O segundo
capĂtulo consistiu numa abordagem conceptual que incidiu sobre a clarificação da
definição de enoturismo, e o comportamento do enoturista em particular. Este capĂtulo
tambĂ©m explorou as possĂveis relações entre os construtos (envolvimento, emoções do
destino, apego ao lugar e intenções comportamentais), que determinam a preposição chave que decorre de sua interação. No terceiro capĂtulo, uma pesquisa quantitativa, foi
utilizado um questionário estruturado nas caves do vinho do Porto, para validar e dar
evidĂŞncias empĂricas sobre o comportamento do visitante nas caves do vinho do Porto.
Foi realizada a análise multivariada do modelo estrutural proposto, utilizando o software
SmartPLS, que permitiu a confirmação de todas as hipóteses propostas.
No primeiro capĂtulo, os resultados forneceram um suporte teĂłrico da relevância dos
construtos do envolvimento e das emoções na área do turismo. A análise de conteúdo
produziu perceções com base em conceitos e definições destes dois construtos, numa
perspetiva mais holĂstica. No segundo capĂtulo, os resultados sustentam o especial
interesse no comportamento do consumidor no enoturismo, e foi apresentado um
conjunto de 5 preposições, onde os principais construtos são interligados. No terceiro
capĂtulo, os resultados empĂricos indicam que o envolvimento pessoal dos enoturistas e
o seu envolvimento com o produto vinho tĂŞm uma influĂŞncia significativa (e um efeito
direto) sobre as emoções do destino e o apego ao lugar, impulsionando as suas intenções
comportamentais.
O estudo teve implicações diretas (análise e avaliação do comportamento de viagem do
enoturista e perfil do enoturista) para as caves do vinho do Porto. Os resultados levaram
a implicações práticas e sugestões para os gestores de enoturismo.
Cette étude a pour but contribuer pour le développement conceptuel du comportement
du consommateur en oenotourisme, apportant une nouvelle discussion et des Ă©vidences
empiriques. Il a été faite une révision de la littérature à propos des principaux concepts,
a fin de développer et soutenir un modèle conceptuel. Ce modèle a été ensuite validé et
testé empiriquement, et il a été établi un rapport hypothétique entre les concepts :
engagement (engagement personnel et engagement avec le produit vin), Ă©motions du
destin, attachement à l’endroit (identité et dépendance de l’endroit). Celle-ci c’est,
jusqu`à présent, la première étude qui analyse l’interaction combinée des tous ces
concepts. Cette recherche a été réalisée dans le cadre de l’oenotourisme, ça veut dire le
mesurage du comportement de l’oenotouriste après visiter les caves du vin Porto.
Méthodologiquement le premier chapitre c’est une étude qualitative exploratoire qui a
réalisé une analyse du contenu sur les concepts clé (engagement et émotions), en
permettant une meilleure compréhension de la façon dont ils peuvent être définis, ainsi
que les dimensions principales inhérentes à chacun d’eux. Le second chapitre a consisté
dans une approche conceptuelle qui portait sur la précision de la définition de
l’oenotourisme, et le comportement de l’oenotouriste en particulier. Ce chapitre a aussi
exploité les éventuels rapports entre les concepts (engagement, émotions du destin,
attachement à l’endroit et intentions comportementales) qui postulent la préposition clé qui découle de son interaction. Dans le troisième chapitre, une recherche quantitative, il
a été utilisé un questionnaire structuré dans les caves du vin Porto, a fin de valider et de
donner des Ă©vidences empiriques sur le comportement du visiteur dans les caves du vin
Porto. Il a été réalisé l’analyse multifactorielle du modèle structurel proposé, en utilisant
le software SmartPLS qui a permis la confirmation de toutes les hypothèses proposées.
Dans le premier article, les résultats ont fourni un soutien théorique de la pertinence des
concepts de l’engagement et des émotions dans le domaine du tourisme. L’analyse du
contenu a produit des perceptions ayant comme base des conceptions et définitions de
ces deux concepts, dans un point de vue plus holistique. Dans le second article, les
résultats soutiennent le spécial intérêt dans le comportement du consommateur dans
l’oenotourisme, et il a été présenté un ensemble de 5 prépositions, où les principales
constructions sont interconnectées. Dans le troisième article, les résultats empiriques
indiquent que l’engagement avec le produit vin ont une influence significative (et un
effet direct) sur les émotions du destin et l’attachement à l’endroit, en poussant ses
intentions comportementales.
L’étude a eu des implications directes (analyse et évaluation du comportement de
voyage de l’oenotouriste et profil de l’oenotouriste) pour les caves du vin Porto. Les
résultats ont amené à des implications pratiques et suggestions pour les gestionnaires de
l’oenotourisme
Presence 2005: the eighth annual international workshop on presence, 21-23 September, 2005 University College London (Conference proceedings)
OVERVIEW (taken from the CALL FOR PAPERS)
Academics and practitioners with an interest in the concept of (tele)presence are invited to submit their work for presentation at PRESENCE 2005 at University College London in London, England, September 21-23, 2005.
The eighth in a series of highly successful international workshops, PRESENCE 2005 will provide an open discussion forum to share ideas regarding concepts and theories, measurement techniques, technology, and applications related to presence, the psychological state or subjective perception in which a person fails to accurately and completely acknowledge the role of technology in an experience, including the sense of 'being there' experienced by users of advanced media such as virtual reality.
The concept of presence in virtual environments has been around for at least 15 years, and the earlier idea of telepresence at least since Minsky's seminal paper in 1980. Recently there has been a burst of funded research activity in this area for the first time with the European FET Presence Research initiative. What do we really know about presence and its determinants? How can presence be successfully delivered with today's technology? This conference invites papers that are based on empirical results from studies of presence and related issues and/or which contribute to the technology for the delivery of presence. Papers that make substantial advances in theoretical understanding of presence are also welcome. The interest is not solely in virtual environments but in mixed reality environments. Submissions will be reviewed more rigorously than in previous conferences. High quality papers are therefore sought which make substantial contributions to the field.
Approximately 20 papers will be selected for two successive special issues for the journal Presence: Teleoperators and Virtual Environments.
PRESENCE 2005 takes place in London and is hosted by University College London. The conference is organized by ISPR, the International Society for Presence Research and is supported by the European Commission's FET Presence Research Initiative through the Presencia and IST OMNIPRES projects and by University College London

Library websites popularity: does Facebook really matter?
The purpose of this paper is to determine whether the utilization of social media (Facebook) is an important factor in increasing the visibility of the library site usage in Malaysian public universities. Nine top ranked Malaysian public universities involved in this research and number of Facebook followers for each library website is listed. Alexa software was used as the approach to study the issue of visibility. Alexa is able to determine web site usage, by showing the percentage of visitors of library related subdomain(s) as listed in the top subdomains for each University website (domain) over a month. It is found that Universiti Utara Malaysia library website scored the highest percentage of visitors based on the library related subdomain(s) as listed in the top subdomains for the University website in Alexa. To check such irregularities in access, this paper use EvalAccess 2.0 and it is found that Universiti Sains Malaysia’s library website scored higher irregularities. In term of number of Facebook followers, Univesity of Malaya library has the highest score. It is showed that the utilization of social media (Facebook) is not yet an important factor in increasing the visibility of the library websites. However, expectedly, top ranked universities’ library web sites, are more visible and popular. This research is limited to the situation in Malaysia where public universities are more noticeable and seldom face financial constraints rather than private universities. It is highly important for those universities’ library web sites that are not highly visible to initiate the necessary measures in improving the development of their web sites as the usage of the website is an indicator of online quality
