Comunicação online para a saúde cardiovascular: a mensagem das entidades públicas de saúde e de cardiologia portuguesas e a sua receção por residentes do concelho de Lisboa
Tese especialmente elaborada para obtenção do grau de Doutor em Ciências da ComunicaçãoA comunicação é, de acordo com a revisão da literatura, um pilar para a saúde, funcionando
como um reforço na promoção da saúde e na prevenção e tratamento da doença. As redes
sociais online e os websites têm sido utilizados neste sentido, existindo, no entanto, algumas
relutâncias quanto à sua viabilidade, tendo em conta que são ferramentas relativamente
recentes e existe uma certa desconfiança que as envolve. As doenças cardiovasculares são as
principais causas de morte em Portugal e em todo o mundo.
Esta tese propõe-se a caracterizar a mensagem presente no Facebook e nos websites de
três entidades públicas de saúde e três organizações cardiovasculares portuguesas, bem como
o seu potencial retórico. Adicionalmente, identificam-se as melhores práticas destacadas pelos
emissores e as preferências dos recetores – residentes do concelho de Lisboa.
A investigação apoia-se no método misto, incluindo a análise de conteúdo, a análise de
websites, a análise retórica, a entrevista e o inquérito por questionário. Ancorou-se no
funcionalismo e no interpretativismo, no domínio da epistemologia e, quanto às teorias, na
teoria dos usos e gratificações, na teoria da retórica, no modelo encoding-decoding, no framing,
no modelo de crenças em saúde e no modelo transteórico para a mudança de comportamento.
Entre os resultados, anota-se a atenção das entidades emissoras em querer informar,
mantendo uma lógica pedagógica que se sobrepõe a uma lógica influenciadora de
comportamentos saudáveis. Além disso, identifica-se um valor direcional da mensagem
significativamente neutral, que desvenda um uso envergonhado dos apelos às emoções. No
entanto, o Facebook e websites são considerados ferramentas promissoras no reforço para a
mudança para comportamentos saudáveis, considerando as respostas dos inquiridos e
cumprindo a maioria dos requisitos de veracidade da informação. Assim, entende-se que exista
o uso ativo do Facebook e dos websites no âmbito da comunicação para a saúde cardiovascular,
ainda que recatado, não colocando em prática várias estratégias desenhadas pelas teorias.Communication is, according to the literature review, a pillar for health, working as a
reinforcement in health promotion and disease prevention and treatment. Online social media
and websites have been used in this sense, although there are some reluctances regarding their
viability, due to their relatively recent tools and a certain mistrust that surrounds them.
Cardiovascular diseases are the main causes of death in Portugal and worldwide.
This thesis aims to characterize the message present on Facebook and on the websites of three
public health entities and three Portuguese cardiovascular organizations, as well as its rhetorical
potential. Additionally, the best practices highlighted by the issuers and the preferences of the
receivers – residents of the municipality of Lisbon – are identified.
The investigation is based on the mixed method, including content analysis, website analysis,
rhetorical analysis, interview, and questionnaire survey. It was anchored in functionalism and
interpretivism, in the domain of epistemology and, in terms of theories, in the theory of uses
and gratifications, in the theory of rhetoric, in the encoding-decoding model, in framing, in the
health belief model and in the transtheoretical model for behavior change.
Among the results, the entities' aim to inform is noticed, maintaining a pedagogical logic that
overlaps a logic that influences healthy behaviors. In addition, a significantly neutral directional
value of the message is identified, which reveals a shy use of appeals to emotions. However,
Facebook and websites are considered promising tools in reinforcing the change to healthy
behaviors, considering the respondents' responses, and fulfilling most of the information
veracity requirements. Thus, it is understood that there is an active use of Facebook and
websites in the context of communication for cardiovascular health, even if modest, not putting
into practice various strategies designed by theories.N/
A contrapropaganda na comunicação eleitoral: análise aos cartazes das eleições legislativas e presidenciais portuguesas de 2001 a 2016
Dissertação de Mestrado em Comunicação Social, na vertente de Comunicação EstratégicaComprometendo-se a aferir os objetivos da campanha contrapropagandística, esta
investigação intenta também apurar a estratégia e especificidades dos cartazes
contrapropagandísticos, compreender como os inquiridos lisboetas os percecionam e
identificar quais as características comuns do uso da contrapropaganda nos cartazes, visa
responder à pergunta de partida Qual o contributo da contrapropaganda para os cartazes
políticos nas eleições legislativas e presidenciais portuguesas de 2001 a 2016?
A abordagem metodológica é qualitativa e quantitativa, compondo-se da pesquisa
documental, da entrevista individual em profundidade, do focus group, do inquérito por
questionário online, da análise de conteúdo e semiológica.
Segundo os resultados, os principais objetivos da campanha contrapropagandística
são prejudicar a mensagem do adversário, limitar a sua aceitação e identificar incoerências
nas propostas rivais. O cartaz contrapropagandístico tende a recorrer a figuras políticas
concorrentes como protagonistas, cores da bandeira portuguesa, o ângulo normal, e a regra
“referência a medidas políticas dos adversários”. Os inquiridos avaliam a contrapropaganda
como “importante”, o cartaz contrapropagandístico como sendo mais chamativo, e a regra
mais eficaz a “colocação da propaganda do adversário em contradição com os factos”.
Os inquiridos que votam sempre, ou quase sempre, e dizem estar informados e ter
interesse na política, tendem a rejeitar o cartaz contrapropagandísticoBesides wanting to know the purposes of counterpropaganda, this investigation
aims to study the strategy and specificities of counterpropagandatic posters, to understand
how the respondents perceive them and to identify the common characteristics of the use
of counterpropaganda in posters, in order to answer the question of departure What is the
contribution of counterpropaganda to political posters in the Portuguese legislative and
presidential elections from 2001 to 2016?
The methodological approach is qualitative and quantitative, consisting of
documentary research, individual in-depth interview, focus group, online questionnaire
survey, content analysis and semiology.
According to the results, the main objectives of the counterpropagandist campaign
are to undermine the adversary's message, limit its acceptance and identify inconsistencies
in rival proposals. The counterpropagandistic poster tends to appeal to political figures
competing as protagonists, colors of the Portuguese flag, the normal angle, and the rule
"reference to political measures of opponents." Respondents rate counterpropaganda as
"important," the counterpropagandatic poster as being flashier, and the most effective rule
is "placing adversarial propaganda in contradiction with the facts."
Respondents who always vote, or almost always, and say they are informed and
interested in politics, tend to reject the counterpropagandistic posterN/
Giving a ”like” to cardiovascular health: the positive and negative strategy and the reception of Facebook messages from public health entities and Portuguese cardiology organizations
As doenças cardiovasculares (DCV) continuam a ser a principal causa de morte em Portugal e em todo
o mundo (Direção-Geral da Saúde [DGS], 2017, p. 5), ainda que exista uma melhoria em comparação
com décadas anteriores. Essa redução é atribuída a comunicação, um pilar para a saúde. Com o advento
da inovação nas tecnologias digitais, alguns autores têm apontado para o contributo das redes sociais
online na promoção da saúde e prevenção da doença (e.g. Parvanta & Bass, 2020)
O presente artigo concentra-se na comunicação online sobre DCV, examinando especificamente as
mensagens do Facebook de entidades de saúde pública e organizações de cardiologia portuguesas.
Tem como objetivo conhecer as estratégias persuasivas adotadas e a sua receção pelos residentes do concelho de Lisboa, utilizando a teoria do enquadramento (Rice & Atkin, 2013) e o paradigma de
codificação-descodificação (Hall, 1973), em contexto online. A pesquisa foca-se na produção e nos
efeitos das mensagens que utilizam estratégias positivas e negativas, explorando dimensões cognitivas,
emocionais e comportamentais. O estudo aplica análise de conteúdo – a publicações do Facebook – e
um inquérito por questionário – aos residentes do concelho de Lisboa. Os resultados apresentam
paradoxos, uma vez que sugerem que a negatividade desperta mais emoções e tem mais potencial
para a mudança comportamental, mas pode negligenciar o aspeto pedagógico associado à comunicação
para a saúde. É por isso recomendada a comparação dos resultados com outros países, para entender
a estratégia de mensagem em cardiologia e a sua receção de forma internacional, bem como o estudo
do uso e receção da abordagem negativa e positiva na comunicação de prevenção de outras doenças.Cardiovascular diseases (CVD) continue to be the leading cause of death in Portugal and worldwide
(Direção-Geral da Saúde [DGS], 2017, p. 5), although there has been an improvement compared to
previous decades. This reduction is attributed to communication, a cornerstone for health. With the
advent of innovation in digital technologies, some authors have pointed to the contribution of online
social networks in promoting health and disease prevention (e.g. Parvanta & Bass, 2020).
This article focuses on online communication about CVD, specifically examining the Facebook messages
of public health entities and Portuguese cardiology organizations. It aims to know the persuasive
strategies adopted and their reception by residents in the Lisbon district, using framing theory (Rice &
Atkin, 2013) and the encoding-decoding paradigm (Hall, 1973) in an online context. The research
focuses on the production and effects of messages utilizing positive and negative strategies, exploring
cognitive, emotional, and behavioral dimensions. The study employs content analysis to Facebook posts
and a survey administered to residents in the Lisbon municipality.
The findings present paradoxes, as they suggest that negativity elicits more emotions and has more
potential for behavior change, but it may overlook the pedagogical aspect associated with health
communication. Therefore, it is recommended to compare the results with other countries to
understand the messaging strategy in cardiology and its reception on an international scale, as well as
to study the use and reception of negative and positive approaches in communicating the prevention
of other diseases.info:eu-repo/semantics/publishedVersio
“No, you cannot”: O cartaz contrapropagandístico e estratégias de persuasão nas eleições legislativas e presidenciais portuguesas de 2001 a 2016
Este artigo foca‑‑se no cartaz com feição de contrapropaganda e na sua estratégia persuasiva nas eleições legislativas e presidenciais portuguesas de 2001 a 2016. Visa apurar a estratégia e especificidades dos cartazes e perceber a sua capacidade persuasiva sobre o eleitorado. A abordagem metodológica é mista, compondo‑‑se da análise de conteúdo e semiológica e do inquérito por questionário online aplicado aos lisboetas. Os resultados indicam que o cartaz contrapropagandístico tende a usar políticos concorrentes como protagonistas, o excesso de tempo governativo como assunto e a regra “referência a medidas políticas dos adversários”. Os inquiridos avaliam a regra “colocação da propaganda do adversário em contradição com os factos” como a mais eficaz. Apura‑‑se quatro relações estatisticamente significativas
Educomunicación y Empoderamiento en la Salud Cardiovascular de Residentes de Lisboa
Online educommunication and empowerment are crucial dimensions in awareness, literacy and change processes, and their articulation may bring benefits to cardiovascular health, given that cardiovascular diseases are the deadliest in the world, including in Portugal. This paper aims to explore the relationship between online educommunication and empowerment in cardiovascular health, using Lisbon citizens as a case. The theoretical framework is composed by the interactivity and empowerment model, the health belief model and the uses and gratifications theory. The questionnaire survey was applied to a gender and age quota sample (N=400). The questionnaire includes thematic dimensions, such as online informative practices on cardiovascular health, the eHEALS scale, and the importance and effectiveness of the educommunicative message on cardiovascular health features. Results show that the educommunicative message has characteristics at the level of purpose, content, type, format, emotions, and logic, which enhance it the most. This indicates that exposure to messages with these characteristics may instigate empowerment and behavior change. Respondents self-rated with the most positive levels on the eHEALS scale, showing empowerment at the eHealth level, with age rather than gender differences. There is evidence that eHealth skills and having cardiovascular disease influence information seeking and empowerment. The main contribution lies in identifying characteristics of the cardiovascular health educommunication message that can optimize recipient’s empowerment.La educomunicación en línea y el empoderamiento son dimensiones cruciales en los procesos de concienciación, alfabetización
y cambio, y su articulación puede aportar beneficios a la salud cardiovascular, dado que las enfermedades cardiovasculares son
las más mortíferas del mundo, incluso en Portugal. Este trabajo pretende explorar la relación entre educomunicación online y
empoderamiento en salud cardiovascular, utilizando como caso los residentes del municipio de Lisboa. El marco teórico está
compuesto por el modelo de interactividad y empoderamiento, el modelo de creencias en salud y la teoría de usos y gratificaciones.
El cuestionario se aplica a una muestra por cuotas de sexo y edad (N=400). El cuestionario incluye dimensiones temáticas, como
las prácticas informativas en línea sobre salud cardiovascular, la escala eHEALS, la importancia y la eficacia de las características
del mensaje educomunicativo sobre salud cardiovascular. Los resultados muestran que el mensaje educomunicativo tiene
características a nivel de propósito, contenido, tipo, formato, emociones y lógica, que lo realzan más, según la evaluación de los
encuestados. Esto indica que la exposición a mensajes con estas características puede instigar la capacitación y el cambio de
comportamiento. Los encuestados se autocalificaron con los niveles más positivos en la escala eHEALS, lo que demuestra su
capacitación a nivel de eSalud, con diferencias más de edad que género. Existen pruebas de que las competencias en eSalud y
el hecho de padecer una enfermedad cardiovascular influyen en la búsqueda de información y en la capacitación.info:eu-repo/semantics/publishedVersio
Fiber Optic Sensing System for Temperature and Gas Monitoring in Coal Waste Pile Combustion Environments
International audienceIt is presented an optical fiber sensing system projected to operate in the demanding conditions associated with coal waste piles in combustion. Distributed temperature measurement and spot gas sensing are requirements for such a system. A field prototype has been installed and is continuously gathering data, which will input a geological model of the coal waste piles in combustion aiming to understand their dynamics and evolution. Results are presented on distributed temperature and ammonia measurement, being noticed any significant methane emission in the short time period considered. Carbon dioxide is also a targeted gas for measurement, with validated results available soon. The assessment of this technology as an effective and reliable tool to address the problem of monitoring coal waste piles in combustion opens the possibility of its widespread application in view of the worldwide presence of coal related fires
Towards the new Thematic Core Service Tsunami within the EPOS Research Infrastructure
Tsunamis constitute a significant hazard for European coastal populations, and the impact of tsunami events worldwide can extend well beyond the coastal regions directly affected. Understanding the complex mechanisms of tsunami generation, propagation, and inundation, as well as managing the tsunami risk, requires multidisciplinary research and infrastructures that cross national boundaries. Recent decades have seen both great advances in tsunami science and consolidation of the European tsunami research community. A recurring theme has been the need for a sustainable platform for coordinated tsunami community activities and a hub for tsunami services. Following about three years of preparation, in July 2021, the European tsunami community attained the status of Candidate Thematic Core Service (cTCS) within the European Plate Observing System (EPOS) Research Infrastructure. Within a transition period of three years, the Tsunami candidate TCS is anticipated to develop into a fully operational EPOS TCS. We here outline the path taken to reach this point, and the envisaged form of the future EPOS TCS Tsunami. Our cTCS is planned to be organised within four thematic pillars: (1) Support to Tsunami Service Providers, (2) Tsunami Data, (3) Numerical Models, and (4) Hazard and Risk Products. We outline how identified needs in tsunami science and tsunami risk mitigation will be addressed within this structure and how participation within EPOS will become an integration point for community development

Highly-Birefringent Photonic Bandgap Bragg Fiber Loop Mirror for Sensing Applications
International audienceA highly-birefringent photonic bandgap Bragg fiber loop mirror sensor is proposed. Thanks to the Bragg fiber geometry, one can observe the group birefringence and the bandgap fiber in the transfer function. The sensing head presented different sensitivities for strain and temperature measurements. Using the matrix method, both the physical parameters can be discriminated. It is important to highlight that this Bragg fiber presents sensitivity to temperature of ~5.75 nm/ºC, for the group birefringence measurand
