Os intelectuais portugueses durante o Estado Novo: percursos e posicionamentos

Algum tempo após o golpe militar de 1926 toma forma um regime autoritário – o Estado Novo, cuja duração irá para além das expectativas dos intelectuais republicanos, muitos dos quais passam para a oposição, enquanto outros se aclimatam melhor. Se a relevância dos intelectuais para as sociedades contemporâneas (Winnock) é incontestável, a polarização do campo intelectual (Bourdieu) durante o Estado Novo, caracterizada por profundas tensões políticoideológicas, é uma realidade pouco estudada na sua globalidade, encontrando-se personalidades num leque ideal-típico que vai do intelectual orgânico de Gramsci, que frequentemente integra a elite governante (Pareto), ao clerc de Benda com um ideal de pensamento livre e crítico, para além dos vínculos ideológicos. Durante grande parte do Estado Novo, o prestígio do intelectual, que não integra a elite governante, resulta sobretudo da sua actividade pública, enquanto publicista, escritor de ideias ou produtor de obras artísticas, integrando movimentos culturais e associações cívico-políticas; apenas alguns dos intelectuais são académicos: cientistas, médicos, historiadores, etc. Se numa primeira fase se destacam na agitação intelectual de oposição à Ditadura Militar e ao Estado Novo figuras associadas à «Renascença Portuguesa» ou à «Seara Nova», numa segunda fase, com o final da II Guerra Mundial, que levou muitos dos republicanos e democratas a idealizar uma abertura de regime, surgem personalidades e movimentos com outros referenciais (ligados por exemplo ao marxismo-leninismo tão presente na revista «Vértice»). No pós-guerra há uma reestruturação do campo intelectual, mantendo-se uma forte interacção entre gerações, fenómeno bem patente no MUD ou na candidatura do general Humberto Delgado. Este livro inclui uma introdução geral e compila as sínteses das comunicações apresentadas no Seminário – Os intelectuais portugueses durante o Estado Novo: percursos e posicionamentos, realizado em Junho de 2017 na Universidade de Évora

A new construct to measure participation on social networking sites

Langaro, D., Salgueiro, M. D. F., & Rita, P. (2020). Users' brand page participation: A new construct to measure participation on social networking sites. International Journal of Internet Marketing and Advertising, 14(2), 135-151. https://doi.org/10.1504/IJIMA.2020.107658The increasing development of brand presence on social networking sites (SNS) requires new practices for monitoring the results of brands' efforts. The current research proposes that users' exposure to brand-related content by means of participating on brand pages is a key measure to be monitored. This proposition builds on previous studies which relate positive business consequences with users' exposure to brand communications. Despite the relevance of capturing users' participation on brand pages, so far very limited effort has been made to propose a construct for measuring it. Thus, three studies were implemented and a new construct was proposed and validated for internal consistency, unidimensionality and nomological validity.authorsversionpublishe

History, Science and Nature: boundless frontiers...

The interface between History, Science and Nature is dynamic and vital for deepening knowledge about the uses of the planet and nature (Earth / Oceans / Seas), understanding it as an agent of modernization of economic, social, scientific and cultural of states and nations (Horden et al. 2006; Rozwadowski 2014; García 2014). Nature can also be seen as an agent of new scientific and cultural practices of sociabilities, representative of new political, philosophical and social ideals, in which the production, circulation and appropriation of knowledge and its techniques is a reality (Wigen 2006; Brito 2010; Salgueiro et al. 2014). There is a brave new world waiting for new relations that unite different spatialities and mentalities, enhancing intercultural encounters, manifested in official reports, explorers' reports, and the constitution of libraries, museums, collections and scientific objects (Lopes 2009; Felismino 2014; Granato & Lourenço 2014; Albuquerque 2015; Nunes 2016; Pereira 2017)

The manifest association structure of the single-factor model: insights from partial correlations

The association structure between manifest variables arising from the single-factor model is investigated using partial correlations. The additional insights to the practitioner provided by partial correlations for detecting a single-factor model are discussed. The parameter space for the partial correlations is presented, as are the patterns of signs in a matrix containing the partial correlations that are not compatible with a single-factor model

Estudo sobre a validação do “Modelo de Comportamento Organizacional” de Meyer e Allen para o contexto português

Um dos modelos do comprometimento organizacional que tem revelado maior consistência nos diversos estudos em que foi utilizado, é o “Modelo das Três-Componentes” de Meyer e Allen (1991). Os autores (Meyer & Allen, 1997) propõem, também, três escalas que permitem a medição das componentes afectiva, calculativa e normativa do comprometimento organizacional. O presente trabalho tem como objectivo contribuir para o estudo da validação, no contexto português, do referido modelo e das três escalas a ele associadas. Os resultados obtidos permitiram identificar uma componente afectiva, calculativa e normativa do comprometimento organizacional, conforme o estabelecido pelos autores. No entanto, os resultados não permitiram a validação do modelo. Na realidade, foi encontrada uma estrutura de relações entre as três componentes que não está em linha com a do quadro teórico e empírico estabelecido. Por fim, os resultados permitiram validar as três escalas. Todavia houve a necessidade de considerar a eliminação de alguns dos itens originais. Foram discutidas as implicações destes resultados e sugeridos estudos futuros

Sporotrichoid leishmaniasis: a cross-sectional clinical, epidemiological and laboratory study in Rio de Janeiro State, Brazil

Background Atypical presentations of cutaneous leishmaniasis include sporotrichoid leishmaniasis (SL), which is clinically described as a primary ulcer combined with lymphangitis and nodules and/or ulcerated lesions along its pathway. Aims To assess the differences between patients with sporotrichoid leishmaniasis and typical cutaneous leishmaniasis (CL). Methods From January 2004 to December 2010, 23 cases of SL (4.7%) were detected among 494 CL patients diagnosed at a reference center for the disease in Rio de Janeiro State, Brazil. These 23 cases were compared with the remaining 471 patients presenting CL. Results SL predominated in female patients (60.9%, p = 0.024), with older age (p = 0.032) and with lesions in upper limbs (52.2%, p = 0.028). CL affected more men (64.5%), at younger age, and with a higher number of lesions exclusively in lower limbs (34.8%). Conclusions Differences in clinical and epidemiological presentation were found between SL patients as compared to CL ones, in a region with a known predominance of Leishmania (Viannia) braziliensis. The results are similar to the features of most of the sporotrichosis patients as described in literature, making the differential diagnosis between ATL and sporotrichosis more important in overlapping areas for both diseases, like in Rio de Janeiro State

Unraveling the forcings controlling the vegetation and climate of the best orbital analogues for the present interglacial in SW Europe

The suitability of MIS 11c and MIS 19c as analogues of our present interglacial and its natural evolution is still debated. Here we examine the regional expression of the Holocene and its orbital analogues over SW Iberia using a model-data comparison approach. Regional tree fraction and climate based on snapshot and transient experiments using the LOVECLIM model are evaluated against the terrestrial-marine profiles from Site U1385 documenting the regional vegetation and climatic changes. The pollen-based reconstructions show a larger forest optimum during the Holocene compared to MIS 11c and MIS 19c, putting into question their analogy in SW Europe. Pollen-based and model results indicate reduced MIS 11c forest cover compared to the Holocene primarily driven by lower winter precipitation, which is critical for Mediterranean forest development. Decreased precipitation was possibly induced by the amplified MIS 11c latitudinal insolation and temperature gradient that shifted the westerlies northwards. In contrast, the reconstructed lower forest optimum at MIS 19c is not reproduced by the simulations probably due to the lack of Eurasian ice sheets and its related feedbacks in the model. Transient experiments with time-varying insolation and CO2 reveal that the SW Iberian forest dynamics over the interglacials are mostly coupled to changes in winter precipitation mainly controlled by precession, CO2 playing a negligible role. Model simulations reproduce the observed persistent vegetation changes at millennial time scales in SW Iberia and the strong forest reductions marking the end of the interglacial "optimum".SFRH/BD/9079/2012, SFRH/BPD/108712/2015, SFRH/BPD/108600/2015info:eu-repo/semantics/publishedVersio

Misspecification effects in the analysis of panel data

Misspecification effects (meffs) measure the effect on the sampling variance of an estimator of incorrect specification of both the sampling scheme and the model considered. We assess the effect of various features of complex sampling schemes on the inferences drawn from models for panel data using meffs. Many longitudinal social survey designs employ multistage sampling, leading to some clustering, which tends to lead to meffs greater than unity. An empirical study using data from the British Household Panel Survey is conducted, and a simulation study is performed. Our results suggest that clustering impacts are stronger for longitudinal studies than for cross-sectional studies, and that meffs for the regression coefficients increase with the number of waves analysed. Hence, estimated standard errors in the analysis of panel data can be misleading if any clustering is ignore
