Adaptive Non-Immersive VR Environment for Eliciting Fear of Cockroaches : a Physiology-Driven Approach Combined with 3D-TV Exposure
(International Journal of Psychological Research, 2020) Rosa, Pedro Joel; Luz, FIlipe Costa; Junior, Roberto; Oliveira, Jorge; Morais, Diogo; Gamito, Pedro; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
Non-immersive VR environments are related to the least interactive application of VR techniques, such that interaction with the VR environment can occur commonly by 3D-TV without full immersion into the environment. This study presents how 3D-TV exposure combined with physiology recording can elicit fear of cockroaches among individuals with different levels of fear. Thirty-six participants, set apart into three fear groups (low vs. moderate vs. high), were exposed to VR environment with cockroaches for 4 minutes while recording and using cardiac activity as input to the VR environment. Results revealed significant effects on self-report measures and heart rate between different fear groups. Moreover, participants with higher levels of fear were more likely to trigger cockroaches into the scenario due to their cardiac acceleration. Overall results suggest that our physiology-driven VR environment is valid for fear elicitation while having potential use in therapeutic domain.
Anatomy Primitives
(Edições Centro de Investigação em Artes e Comunicação, 2021-10) Araújo, António; Silva, Horácio Hugo Ferreira Faria de Azevedo e; Escola de Comunicação, Arquitetura, Artes e Tecnologias da Informação
We propose an installation that investigates the notion of the anatomical canon and its conceptual and practical role in the artistic modeling of human anatomy. This installation guides the visitor through the synthesis of a digital canon built from standard 3D primitives. Through a model that can be interactively constructed or deconstructed step-by-step, using simple controls, the visitoris invited to study, and draw, the human surface anatomy and its main features as interpreted through the natural tools of digital modeling.
O Aplanamento das Imagens
(Edições Universitárias Lusófonas, 2007) Viveiros, Paulo; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
A densidade visual da pintura flamenga e holandesa afirmou-se devido a uma nova forma de conceber o mundo e o olhar, fornecendo óptimos exemplos de comparação para com o actual cinema digital, desde as epopeias densamente habitadas por milhares de figurantes em programas de auto-gestão, até à densidade visual das layers de pósprodução. Christine Buci-Glucksmann chamou-lhe “olho cartográfico” e Svetlana Alpers “arte da descrição”. Ambos os conceitos lidam com um olhar nómada, presente também nos panoramas dos séculos XVIII e XIX, devido a enquadramentos arbitrários, mas onde os amplos espaços enquadrados, num ponto de vista ideal, por vezes funcionam como controlo do mundo através da “panoramização” do espaço, que lhe retira o relevo, as profundidades distantes e inacessíveis. Tudo está ao alcance do olho. As imagens tornaram-se semelhantes aos mapas, sendo que estes tinham projectado o mundo num plano. Isto gerou um efeito-superfície que se generalizou, transformando paredes em “peles digitais” e a profundidade na horizontalidade plana electrónica, como defende Buci-Gluksmann.
The art of feminist-queering the museum : gate-leaking
(Edições Universitárias Lusófonas, 2020) Grácio, Rita; Coutinho, Andreia C; Falé, Laura; Sobreira, Maribel; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
This paper takes part in the ongoing debate around how museums have begun to address LGBTQI+ and feminist issues in the 21st century. While Portugal is a particularly interesting country to consider, given that it has passed some of the most advanced legislation on LGBTQI+ rights in Europe (Santos 2012), this progressivism is not reflected in Portuguese museum practices, given that gender museology has been slow to emerge (Vaquinhas 2014). After briefly contextualising initiatives addressing gender in Portuguese art museums, we present as a case study Trazer a margem para o centro (Bringing the Margin to the Centre), a series of three talks hosted by the Berardo Collection Museum, which is considered Portugal’s primary modern and contemporary art museum. Unlike previous initiatives in art museums, which were museum-led, the series of talks was led by the small intersectional feminist collective FACA. A sociologist (Rita Grácio) and the three members of FACA (Andreia Coutinho, Laura Falé and Maribel Sobreira) designed and conducted the three talks that constitute the initiative Bringing the Margin to the Centre. Grácio designed and conducted the qualitative study of the audiences that attended Bringing the Margin to the Centre. This study consisted of participant observation at the event series, at which an adapted version of the Personal Meaning Mapping technique (Falk and Storksdieck 2005) was applied; semi-structured phone interviews with participants were then conducted after the event (Falk and Dierking 2011). The main findings show this event raised awareness among cisgender visitors with heteronormative perspectives and provided a space for counter-narratives of the queer community, showing the role of collective curatorial activism and museums in promoting gender equality and inclusiveness, if acting as gate-leakers, rather than as gatekeepers. Hence, museums can provide lessons to other organisations interested in promoting diversity and inclusion.
A atmosfera fílmica como consciência
(Edições Universitárias Lusófonas, 2002) Gil, Inês; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
The concept of "cinematic atmosphere" is complex because its analysis raises the problem of the cinematographic formal construction as inductive medium of the film atmosphere. Moreover, the proper notion of "atmosphere" reveals other concepts more or less controlled by the cinematic elements that will have all the same goal: the recognition of these concepts through the manifestation of the atmosphere.
Belonging to a community: the mediation of belonging
(OberCom, 2012) Damásio, Manuel José; Henriques, Sara; Costa, Conceição; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
This paper introduces the concept of belonging and discusses it in the context of online social networking experience and community experience considering social capital and user’s activities as nuclear concepts to understand collective actions and social relationships mediated by social media. The paper presents an empirical approach based on the study of two local communities and analyses whether interactive social technologies promote greater social involvement and higher production of social capital and participation, that results in a greater sense of belonging within communities. The results indicate a positive relationship between the use of social media and the increase of social capital and sense of belonging. Our work discusses the role and influence of social media in communitarian practices and the relevance social capital theory has as an outcome of media technologies use that result in a greater sense of belonging to a community.
The bodies of the (digitized) body : experiences of sexual(ised) work on OnlyFans
(SMID - Society of Media researchers In Denmark, 2021) Cardoso, Daniel; Scarcelli, Cosimo Marco; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
OnlyFans has enjoyed increasing attention from media and from users and consumers, especially since the start of the covid-19 pandemic, and particularly amongst internet- savy emerging adults. We used semi-structured interviews to collect testimonies from young Italian women (N=20) who sell their own sexual(ised) content on OnlyFans and processed them through Thematic Analysis (Braun & Clarke 2006). Through this process, we sought to explore how different bodies are conceptualized in relation to content production, and how labour takes somatic existence in multiple ways. We looked at (1) how the body is prepared to be presented and mediatized, (2) how its presentation is conceptualized and actualized, and (3) how that work of re-presentation, as a work of networking and therefore where bodily energy is invested and expended. Through this, we show how there are multiple, concurrent and at times contradictory, narratives about corporality, and that potency and healing coexist alongside exhaustion.
Children’s cancer narratives on YouTube : Agency and entrepreneurship in Brazilian CarecaTV
(Edições Universitárias Lusófonas, 2021) Marôpo, Lidia; Carvalho, Raiana de; Jorge, Ana Margarida Ferreira Rato; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
This article looks at the social and cultural contexts of children’s experiences of illness, through a particular focus on the context of the Global South and the role of the social media platform YouTube in children’s culture. It takes a socio-constructivist approach to discuss the case of CarecaTV (BaldTV), a Brazilian YouTube channel with more than one million followers created by Lorena Reginato at the age of 12 when she was recovering from brain cancer. In CarecaTV, cancer subjectivity co-exists with and is expressed through digital commercialization. On the one hand, through this process, Lorena Reginato gains agency as she offers an inspirational and credible first-person testimony about cancer during childhood and becomes an emerging cancer activist. On the other, she uses entrepreneurship strategies associated with the digital influencer model of YouTube to promote herself as a (cancer) micro-celebrity, taking the lead in a youthful and playful culture.
Combining the rational and relational perspectives of electronic trading
(The Operational Research Society, 2009) Redondo, Eduardo; Daniel, Elizabeth; Ward, John; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
Many organisations make extensive use of electronic linkages to facilitate their trading exchanges with partners such as suppliers, distributors and customers. This research explores how the use of inter-organisational systems (IOS) both affects, and is affected by, the relationships between trading partners. In doing this, it brings together two existing but distinct perspectives and literatures; the rational view informed by IOS research, and the behavioural or relationship perspective embodied in inter-organisational relationships (IOR) literature. The research was undertaken in the European paper industry by means of six dyadic case studies. The dyads studied covered both traditional electronic data interchange systems and newer e-marketplace environments. A framework was derived from existing literature that integrates the two perspectives of interest. The framework was used to analyse the case studies undertaken and enabled the inter-relationship between IOS use and IOR to be explained.
Competency management articulation for human resources
(Edições Universitárias Lusófonas, 2008) Teodósio, Fernando; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
In recent years the approach to competences has gained great popularity due to process and organizational reengineering need. Taking opportunity on some recent work in this area dealing challenges that human resources face to develop planning training, I intend to identify several guidelines to develop a future architecture in a practical implementation. At this article is presented the concept development of competency management.
Comunicações Não-coerentes em Sistemas MIMO: Desenho do Receptor e Construção de Códigos
(Edições Universitárias Lusófonas, 2009) Beko, Marko; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
Este trabalho aborda o problema do desenho de códigos espácio-temporais para sistemas de comunicação multiple-input multiple-output (MIMO) sem fios. Considera-se o contexto realista e desafiante da recepção não-coerente (a realização do canal é desconhecida no receptor). O detector conhecido como generalized likelihood ratio test (GLRT)é implementado no receptor e, ao contrário da maioria das abordagens actuais, permite-se uma estrutura de correlação arbitrária para o ruído gaussiano de observação. Apresenta-se uma análise teórica para a probabilidade de erro do detector, em ambos os regimes assimptóticos de relação sinal-ruído (SNR) alta e baixa. Essa análise conduz a um critério de optimalidade para desenho de códigos e permite uma re-interpretação geométrica do problema abordado como um problema de empacotamento óptimo num producto Cartesiano de espaço projectivos. A construção dos códigos implica a resolução de um problema de optimização não-linear, não-diferenciável e de dimensão elevada, o qual foi abordado aqui em duas fases. A primeira fase explora uma relaxação convexa do problema original para obter uma estimativa inicial. A segunda fase, refina essa estimativa através de um algoritmo iterativo de descida do gradiente ao longo de geodésicas, explorando-se assim a geometria Riemanniana imposta pelas restricões de potência sobre os códigos espáciotemporais. Mostra-se que o desempenho dos novos códigos obtidos por este método excede o das soluções previamente conhecidas. De facto, para algumas configurações particulares, estas novas constelações atingem o limiar de Rankin e são por isso garantidamente óptimas.
Constructing sexual victimization: A thematic analysis of reader responses to a literary female-on-male rape story on Goodreads
(Edições Universitárias Lusófonas, 2023) Tselenti, Danai; Cardoso, Daniel; Carvalho, Joana; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
Τhe aim of this study was to provide a detailed understanding of unprompted audience responses to a literary story of female-on-male rape on Goodreads. Thematic analysis of 429 reviews revealed 6 key themes and 12 sub-themes, which evolved around appraising the social function of the book, evaluating its literary features, assessing the depiction of female-on-male rape especially in terms of its perceived realism, as well as around a variety of explicitly emotional and cognitive responses. The aesthetic features of the story proved to be of particular importance for shaping reader engagement. Reflective elaborations on the female rapist were found to constitute a marginal response pattern. Findings identified the existence of an overarching cognitive schema that construes sexual victimization as feminized and is linked to a tripartite pattern of comprehending female on- male rape (female-focused, gender-inclusive, gender-neutral). The study highlights the persistence of gendered rape myths structured around an "ideal victim" - "ideal offender" paradigm, which however co-exist with alternative responses oriented towards de-gendering sexual victimization. These findings suggest the importance of addressing audience responses in future investigations of female sexual violence (hands-on and hands-off behaviors) and pursuing an interventional agenda of more inclusive conceptualizations of victimization.
Defining polyamory : a thematic analysis of lay people's definitions
(Springer New York, 2021) Cardoso, Daniel; Pascoal, Patrícia; Maiochi, Francisco Hertel; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
This study aimed to analyze laypeople’s definitions of polyamory and compare definitions presented by people who are not willing to engage in consensual non-monogamy (CNM) and those who are or are willing to be in a CNM relationship. This exploratory qualitative study used data collected from a convenience sample through a web survey, where people answered the question “What does polyamory mean?” We conducted thematic analysis to examine patterns in meaning and used demographic data to compare themes among groups. The final sample comprised 463 participants aged 18–66 years (M = 32.19, SD = 10.02), mostly heterosexual (60%). Of the total sample, 54% were in a monogamous relationship, followed by 21% not in a relationship, and 13% in a non-monogamous relationship. Analysis showed that people define polyamory mostly as a set of behaviors in a relationship, followed by the potential of multiple relationships or feelings for multiple people. Definitions also include emotional, sexual, and ethical aspects. People in CNM relationships are more likely to define polyamory as constituting a potential form of relating, focus more on interpersonal feelings and ethics, and include consent in their definitions than those unwilling to engage in CNM. People in CNM relationships also focus particularly on the non-central role of sex within these relationships, which might challenge assumptions about sexuality in these relationships in clinical and research settings.
Deleite no obsoleto : o hype vintage da estereoscopia
(Edições Universitárias Lusófonas, 2011) Luz, Filipe Costa; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
Resumo: A história do cinema tem sido feita de enormes avanços tecnológicos devido em grande parte à tecnologia ajudar a vender filmes e permitir conceber novas estéticas narrativas. Apesar de assistimos a um período de um entusiasmo absurdo sobre novos filmes em estereoscopia não são novidade nenhuma, parece-se verificar que com a mesma velocidade com que ressurgiram certamente irão atenuar ou desaparecer. É neste contexto que entendemos a reintrodução da estereoscopia nas salas de cinema, como mais um processo alternativo, obsoleta nos seus princípios, mas que demonstra um enorme potencial criativo para a construção de uma linguagem própria, requerendo uma análise muito mais cuidada do que simplesmente dizer que a televisão e cinema do futuro serão em S3D1. Assim, pretendemos neste trabalho contextualizar a estereoscopia historicamente, tentar justificar nesta tecnologia o paradigma diferente que os filmes em estereoscopia sugere para a tradição narrativa nos filmes ou como permite criar conteúdos alternativos para vanguarda do cinema.

Designing musical expression
(Edições Universitárias Lusófonas, 2017) Sá, Adriana; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
The term New Interface for Musical Expression (NIME) has been applied to a great variety of instruments and systems, since the first NIME conference in 2001. But what is musical expression, and how does an interface intended for idiosyncratic expression differ from ubiquitous interfaces? This paper formulates an understanding where the reciprocal interaction between performer and instrument is important. Drawing from research in perception science , interface design and music, the paper specifies methods that can be used to analyse interaction, attention dynamics and semantics. The methods are applicable to any technical platform and aesthetic approach, facilitating the discussion of creative strategies and the analysis of music experience. The paper uses these methods to describe a NIME that combines an acoustic string instrument and software that operates based on the acoustic sound. The software applies the difference between the detected pitch and the closest tone / half tone to the processing of pre-recorded sounds. The proposed methods help to explain how this NIME enables versatile musical forms, and prevents undesired outcomes. Keywords: NIME, Musical expression, Musical Interface, Perception, Attention, Semantics of Sound
As diferentes construções discursivas do poder: Análise crítica dos discursos políticos de Mário Soares e de Cavaco Silva
(2012) Vieira, Marta Santos; Brito, Manuela Correia de; Álvares, Cláudia; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
O presente artigo pretende analisar as relações entre o discurso político e o poder, aqui entendido como carismático e hegemónico, de modo a compreender as linhas estratégicas de construção do poder do Primeiro-Ministro e do Presidente da República. Iremos analisar o poder weberiano (carismático) e gramsciano (hegemónico) para perceber como se evidencia (nestas dimensões) a construção discursiva dos protagonistas políticos e caracterizar as lideranças do Presidente da República e do Primeiro-Ministro. A metodologia Análise Critica do Discurso (ACD) investiga como é constituída a diferenciação das lideranças no discurso político (Wodak, 2009). O nosso corpora são quatro discursos de tomada de posse referentes ao Presidente da República de Portugal, Mário Soares e ao Primeiro-Ministro de Portugal, Aníbal Cavaco Silva, no período de coabitação (1986-1996) onde se pretende fazer ressaltar elementos que caracterizem as diferentes formas de liderança com vista à sua comparação quanto à estratégia discursividade e à sua contextualização
Digital sex work?: Creating and selling explicit content in OnlyFans
(Routledge, 2022-11-10) Cardoso, Daniel; Chronaki, Despina; Scarcelli, Cosimo Marco; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
Recently, we have seen relatively unknown platforms, like OnlyFans, rise to popularity among producers and consumers of sexual(ised) digital content. This seems to be especially so in the case of young adults who were affected by a sudden disappearance of entry-level jobs in hospitality, retail and associated functions, or diminished university experiences compared to expectations, due to the COVID-19 crisis. Although there is an increasing amount written on young people, sexuality and the media, research on both young adults and their experiences with sexuality online and online sex workers is still lacking, and more so in the case of the use of patronage platforms to sell sexual(ised) content. Focusing on younger women producers, this chapter illustrates their challenges within patriarchal societies and the way in which sex work is heavily gendered. By relying on Thematic Analysis of 20 interviews of Italian emerging adults, our analysis focuses on the self-definition of our participants as sex workers. It examines how OnlyFans creators articulate their professional self through the production of contents, marketing practices and customer relations to understand if and how it is possible to speak about deplatformed sex, and to understand that negotiating the identity of ‘sex worker’ is less about the specific material conditions of those doing content production, and more about the hallmarks of what a ‘job’ is. keywords: sex work ; OnlyFans ; porn ; content producer ; platform labor
The digitalization of analogue stereo photographs and the creation of the digital stereo archive
(Society for Imaging Science and Technology, 2019) Luz, Filipe Costa; Peixoto, Rodrigo; Oliveira, Jorge
This paper analyzes the problems arising from the remediation of the relief effect in the transition from analog to digital of stereo photography. One of the main problems in this conversion is the portability of the awe effect that constitutes an important part of the experience when viewing a stereo pair. This image conversion process, necessary to the creation and dissemination of digital files of 19th century stereoscopic photography, is not linear. The digital stereoscopic projection cards present a number of difficulties for a proper consistency reproduction of the relief effect. Through the study comparison of different viewing apparatus (both digital and analogue including 3D and VR) of a specific stereo image, we will present important results achieved with a sample of 134 participants that were exposed to these devices and propose a guideline manual for the digital stereo archive.
O discurso político e a “revolução democrática” em Portugal: Análise dos discursos presidenciais de Ramalho Eanes e Mário Soares
(Escola Superior de Comunicação Social do Instituto Politécnico de Lisboa, 2013) Álvares, Cláudia; Vieira, Marta Regina Silva dos Santos; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
Este artigo pretende investigar a construção do conceito de democracia nos discursos dos dois presidentes portugueses, Ramalho Eanes e Mário Soares, no período que marca a consolidação da democracia após a autocrática ditadura de Salazar e Caetano que durou quase cinco décadas. O nosso objetivo é caracterizar o discurso presidencial de Ramalho Eanes e Mário Soares, e observar o lugar que o conceito de democracia ocupa nesse discurso e a forma como é abordado. Com este artigo pretendemos apurar como se manifestam as crenças, os assuntos estratégicos e a liderança retórica de Ramalho Eanes e Mário Soares, e onde convergem ou divergem as suas prioridades políticas?
