Dotação eficaz de fisioterapeutas em internamento hospitalar: o método WISN como ferramenta de qualidade e gestão
Publication . Vítor Henriques; de Almeida Fontes, Ana Paula; Fidalgo, Pedro
A dotação de Recursos Humanos (RH) é essencial para a qualidade dos cuidados de saúde e segurança dos doentes. A Fisioterapia enfrenta desafios quanto à alocação eficaz de profissionais, sobretudo em internamento hospitalar. A literatura não identificou ferramentas específicas de gestão de RH aplicáveis à Fisioterapia. Contudo, o Workload Indicators of Staffing Need (WISN) revelou-se uma metodologia promissora, transversal às profissões de saúde. Este estudo apresenta a metodologia WISN como ferramenta de apoio ao cálculo da dotação de Fisioterapeutas em ambiente hospitalar. Trata-se de um estudo observacional, analítico e transversal, baseado em inquéritos a fisioterapeutas, com análise estatística descritiva e inferencial com vistas ao conhecimento dos tempos médios de sessões nas principais áreas funcionais e atividades de apoio e adicionais, os quais no WISN correspondem aos padrões de atividade. Os resultados fornecem parâmetros para aplicação do WISN, como Padrões de Atividade para adultos, que foram de 30, 40 e 30 minutos, e para Pediatria foram 30, 45 e 30 minutos, nas áreas Cardiorrespiratória, Neurológica e Ortotraumatológica, respectivamente. Estes valores são adaptáveis a diferentes unidades de internamento. Conclui-se que o WISN é aplicável à Fisioterapia, contribuindo para uma gestão mais eficaz, cuidados de maior qualidade e segurança para os doentes.
Academic discourses of ecotourism: a comparative analysis of Brazil and Portugal (data sets)
Publication . Matschuk, Tamires Chagas; Perdigão Alexandre Ribeiro, Filipa; Custódio Santos, Margarida
These are datasets from a study of academic discourses on ecotourism. The study aims to identify linguistic patterns, recurring themes and underlying ideological assumptions by exploring discourses constructed by academics affiliated with Brazilian and Portuguese teaching and research institutions. A multi-method qualitative approach is employed, involving a corpus-assisted critical discourse analysis (CDA) of 81 English-language scientific articles and a deductive thematic analysis of 10 interviews with researchers.
Storm impact assessment for Scotland’s wave-dominated sedimentary coasts
Publication . Horsburgh, Nicola; Loureiro, Carlos; Hurst, Martin; Rennie, Alistair; Tyler, Andrew
Along wave-dominated sedimentary coasts, risks posed by chronic coastal erosion and rising sea levels during this century have received much atten-tion. However, extreme wave runup during large storms are still poorly charac-terised at large spatial scales, and can contribute significantly to coastal flooding and erosion. This creates an important challenge for coastal management and adaptation planning. This work presents a national-scale storm impact assessment for Scotland’s wave-dominated sand and gravel coasts. It uses readily available national and European datasets to model extreme total water levels that include storm wave runup, tides, storm surge and changes in mean sea level. Future impacts are assessed by integrating likely climate-driven changes to storm forcing and coastal morphology. Outputs estimate the likely storm impact regime at 50 m alongshore transects in Scotland’s natural sand and gravel coasts for the present day, 2050 and 2100, considering climate change scenarios RCP4.5 and RCP8.5. Results indicate 65%, 11% and 4% of transects currently experience collision, overwash and inundation as the most severe storm impact. Towards 2100, tran-sects in overwash and inundation increase to 20% (22%) for RCP4.5 (RCP8.5), but local increases vary considerably between coastal cells. This study contributes to a strategic, national scale understanding of coastal risk that supports the spatial prioritisation of areas in need of proactive adaptation solutions.
The supply of copper to the settlement of Leceia (Portugal) and the Estremadura region during the third millennium BC
Publication . Valério, Pedro; Cardoso, João Luis; Alves, Luís C.; Soares, António M. Monge
The Chalcolithic settlement of Leceia (Portugal) has one of the largest collections of copper artefacts and metallurgical debris in the Portuguese Estremadura. However, the absence of ores and smelting remains suggests that local metallurgical operations were related to the production of artefacts. In fact, the metal assemblage includes several fragments of flat axes, most of them with traces of sectioning, which may have been used as ingots. In order to validate this hypothesis and to identify the copper sources used, elemental, microstructural and Pb isotope characterisation of five axe-ingots was undertaken. The assemblage turned out to be composed of copper with varying amounts of arsenic (0.08–2.94 wt%) and oxide inclusions (Cu2O and Cu-As-O). Some inclusions containing distinct contents of Bi, Sb and/or Sn were also identified, indicating the exploitation of different sources of copper ores. Pb isotope ratios displayed a cluster of four samples (206Pb/204Pb: 18.2378–18.3444) and one outlier with low radiogenic lead (206Pb/204Pb: 17.6625), signatures that compare well with those previously obtained for local artefacts and prills. Euclidean distances identified ore deposits in the Spanish provinces of Huelva and Cordoba as potential suppliers of copper, particularly the supergene copper ores from the mines of Rio Tinto, Cabezadas del Sandino, Preciosa and Quita Pellejo, all of which are located a considerable distance from the settlement of Leceia. Other probable copper sources are located in the mining districts of Linares-La Carolina and Los Pedroches, situated even further away from the Portuguese Estremadura. Consequently, the copper axe-ingots of Leceia, like the previously analysed local artefacts, provide evidence of long-distance trade relations with south-central Iberian Peninsula, which appear to be shared with coeval settlements in Estremadura, such as Vila Nova de São Pedro and Zambujal.
Do vertebrate-type steroids play a role in bivalve reproduction? a case study across two reproductive cycles of magallana gigas
Publication . Rato, Ana Cláudia Nunes; Joaquim, Sandra; Silva, José Paulo da; Anjos, Catarina; Matias, Domitília; Hubbard, Peter
In bivalves, reproduction is regulated by a complex interaction between endogenous and environmental factors, including temperature and food availability. However, hormonal control of the reproductive cycle in bivalves is poorly understood. There is a general belief that vertebrate-type steroids (testosterone, progesterone and 17βoestradiol) are involved in the reproductive cycle of bivalves, even though the necessary enzymes and receptors for such steroids are apparently lacking in the molluscan genome. To investigate the potential role of vertebratetype steroids in reproduction, the current study characterized two consecutive reproductive cycles of the Pacific oyster (Magallana gigas), integrating biochemical composition, reproductive indices, environmental parameters, and steroid levels. Gonadal index (GI), gonadosomatic index, and condition index exhibited clear seasonal fluctuations. Protein, glycogen, and total lipid displayed distinct seasonal patterns, with protein exhibiting structural functions, whereas glycogen and total lipid acted as energy reserves supporting gametogenesis. Both progesterone (0.69-142.33 ng g− 1 ) and testosterone progesterone (2.55-262 ng g− 1 ) levels fluctuated during sampling; progesterone showed correlations with GI, temperature, and protein content, whereas testosterone was mainly associated with environmental factors. These patterns suggest that progesterone may reflect gonadal tissue development and energetic investment rather than acting as a classical sex steroid. The absence of sexspecific steroid patterns, together with the lack of classical steroid receptors in the molluscan genome, supports the hypothesis of an environmental origin and/or an eco-physiological rather than an endocrine role for vertebrate-type steroids in oysters. These findings demonstrate that hormonal studies in bivalves should integrate biochemical, reproductive, and environmental data to understand reproductive strategies.
