How would tourists use Green Spaces? Case Studies in Lisbon
EntretextosThis report provides in a relative condensed format the results of small-scale study undertaken in Lisbon during the
Meeting of the CyberParks Project (www.cost.eu/COST_Actions/tud/Actions/TU1306). CyberParks is a COST Action
coordinated by the Universidade Lusófona at the CeiED - Interdisciplinary Research Centre for Education and
Development. The Project aims at creating a research platform on the relationship between Information and
Communication Technologies (ICT) and the production of public open spaces, and their relevance to sustainable urban
development. The impacts of this relationship are being explored from social, ecological, urban design and technological
perspectives.
Based on the supposition that the participants of the Meeting are tourists visiting Lisbon, a survey was carried out on
the topic how people actually use and how they would use public spaces. This survey is also the first approach to the
case study areas chosen in Lisbon: Parque Quinta das Conchas and Jardim da Estrela. Both green spaces will be subject
of further studies in the forthcoming years.
This study employed (1) a questionnaire for measuring the user’s experience and preferences, and (2) two different
tracking devices that utilise GNSS (Global Navigation Satellite Systems), in our case the GPS for satellite positioning
technologies. It also presents the results of a study on the relevance of wi-fi in Lisbon’s public spaces. Even considering
that the surveys in Lisbon’s green spaces are a first exercise within the work programme of CyberParks they show
important outcomes. On the one hand, regarding the technologies used and their potential for research and on the
other hand the findings about Lisbon’s green spaces. It should be noted that the conducted surveys and the gathered
data are statistically not representative, but can be characterised as an empirical case and as a showcase, as how
tourists tend to use a green space. The results shows that surveys benefit from multiple research methods and from
combining insights.Este relatório apresenta, em formato condensado, os resultados de um estudo de pequena escala realizado em Lisboa
durante o Seminário do Projeto CyberParks. CyberParks é uma Ação COST coordenada pela Universidade Lusófona/CeiED
- Centro de Estudos Interdisciplinares em Educação e Desenvolvimento. O projeto visa a criação de uma plataforma de
debate sobre a relação entre as Tecnologias de Informação e Comunicação (TIC) e a produção de espaços públicos, e
da sua relevância para o desenvolvimento urbano sustentável. Os impactos dessa relação estão a ser explorados a partir
de perspetivas sociais, ecológicas, tecnológicas e de desenho urbano.
Na sua etapa exploratória, este estudo assenta na suposição de que os participantes do Seminário são turistas de visita
a Lisboa. A partir dos dados recolhidos pelos investigadores envolvidos na ação COST, foi realizada uma análise à forma
como diferentes indivíduos usam, e como poderão usar, diferentes espaços públicos verdes. Este estudo apresenta,
portanto, a primeira abordagem às áreas de estudos selecionadas em Lisboa. São elas o Parque Quinta das Conchas e
o Jardim da Estrela. Ambos os espaços verdes serão objeto de novos estudos nos próximos anos. Neste primeiro estudo
exploratório foram empregues: (1) um questionário, para aferir a experiência de um potencial utilizador e as suas
preferências, e (2) dois dispositivos diferentes de rastreamento que utilizam tecnologia GNSS (Sistemas de Navegação
Global por Satélite) e, no nosso caso, o GPS para as tecnologias de posicionamento por satélite. Ele também apresenta
os resultados de um estudo realizado sobre a relevância do wi-fi em espaços públicos na cidade de Lisboa.
Mesmo considerando que os estudos realizados nos espaços verdes representam um primeiro exercício no âmbito do
programa de trabalho do CyberParks em Lisboa, são aqui revelados resultados importantes. Por um lado, o recurso às
tecnologias utilizadas e seu potencial para a investigação e, por outro lado, os resultados sobre a vivência dos espaços
verdes. Deve-se notar que os dados recolhidos não são estatisticamente representativos, mas evidenciam um caso
empírico de como turistas tendem a usar um espaço verde urbano. A combinação do questionário com novos métodos
digitais resultou num grande ganho de conhecimento, recobrindo as áreas de estudo sob a perspetiva de um turista,
para além de maiores informações sobre as potencialidades e limites da tecnologia digital como ferramenta de
investigação. Os resultados mostram que a investigação no campo social pode se beneficiar da combinação de vários
métodos e técnicas
Exploring the barriers and enablers of Online Education programmes : the specific case of Gender and Geographic Mobility in MBA programmes
Education is one of the corner-stones of modern society, representing a propelling motor of our most needed knowledge accumulation. Yet, interestingly enough, the education industry has demonstrated to be one of the least capable to answer to our increasingly innovative and competitive times. As so, the current education business model has been showing growing offer and demand side pressures, thus creating market gaps to be potentially filled by disruptive innovations, more capable to respond to such market dynamics. This thesis focuses in how the online capabilities are enabling the educational business model to break from some of its strains, as well as allowing it to tackle highly valuable market segments like women and international students, considering the significantly representative USA’s MBA reality. The results found that online education is successfully addressing female learners, vis-à-vis the male-built traditional educational system, due to the flexibility it brings and the use of increasingly user-friendly platforms. By contrast, online MBA’s have not been effectively addressing international students thus tuning down the time-and-space asynchrony benefits of such programmes. Consequently, Massive Open Online Courses, as an emerging and disruptive technology, are grasping this market gap and tackling this growing international demand. Higher Education providers need now to fully rationalize the market dynamics in which they are in and understand the role they want to have in the global arena in order to keep being relevant
Forecasting banking crises in developing countries: a dynamic probit approach
Banking crises have afflicted economies in developing countries at least as much as they have in developed ones. In this paper, we discuss possible indicators that allow an effective forecast of banking crises based on an historical analysis of past crises, and develop several probit models, using yearly data from 1960 to 2014 for 33 developing countries across Latin America, Africa and Asia-Pacific. We find that a dynamic probit model which incorporates exuberance dummy variables gives the best forecasting results. Data on exports, inflation, broad money and birth rate provide the best indicators across the different models tested
Obesidade e saúde oral em crianças e adolescentes
Objetivo: Este estudo procura, através de uma revisão bibliográfica, debater e expor a relação
entre a obesidade e a saúde oral em crianças e adolescentes, com especial foco para as duas
principais causas de perda dentária: a cárie dentária e a doença periodontal.
Metodologia: Foram utilizadas bases de pesquisa, nomeadamente: Scielo Brasil, PubMed,
ScienceDirect, Elsevier, ReasearchGate e Wiley Online Library. As palavras-chave utilizadas
para a pesquisa foram: “Obesity”, “Oral Health”, “Children”, “Adolescents”, “Periodontal
Disease”. Foram ainda estipulados fatores de inclusão e de exclusão para a seleção das
publicações, tendo-se totalizado 25 artigos científicos.
Descrição: A obesidade é considerada uma doença crónica, tendo sido classificada como a
“epidemia global do seculo XXI”. Devido à sua causa multifatorial, suspeita-se que possa estar
relacionada com o desenvolvimento de certas patologias orais. A associação entre a obesidade
e carie dentária é pouco clara. Porém, os processos inflamatórios desencadeados pela primeira
poderão estar na origem e/ou exacerbar o desenvolvimento de doenças periodontais em crianças
e adolescentes.Objective: This study aims, through a bibliographical review, to discuss and expose a
relationship between obesity and oral health in children and adolescents with a special focus on
two main causes of tooth loss: dental caries and periodontal disease.
Methodology: There were used some search databases, namely: Scielo Brasil, PubMed,
ScienceDirect, Elsevier, ReasearchGate and Wiley Online Library. The keywords used were:
"Obesity", "Oral Health", "Children", “Adolescents”, "Periodontal Disease". Inclusion and
exclusion factors were used for the selection of publications, which have totalized 25 scientific
articles.
Description: Obesity is considered a chronic disease, having been classified as the "global
epidemic of the 21st century". Because of its multifactorial cause, it is suspected that it may be
related to the development of certain oral pathologies. The association between obesity and
dental caries is unclear. However, inflammatory processes triggered by the former may be at
the origin and/or exacerbate the development of periodontal diseases in children and
adolescents
Distribution patterns of deep-sea benthopelagic fish off Algarve coast, Portugal
The present study characterises and compares the structure and diversity of the deep-sea benthopelagic
ichthyofauna off the southern Portuguese coast, according to the biomass values –in
kg/(nautical mile)2– of ten teleost and seven chondrichthyan species.
The differences between the biomass of benthopelagic species were assessed by depth interval
and sampling season. It seems clear that even at 100 m depth intervals there are differences within
the fish assemblages, and that a few species make most of the contribution to such differences.
No traces of seasonality or even differences between the sampling years have been found.
There is a separation between slope habitat
