    Visitors come to experience science: Towards a non-obtrusive evaluation method based on immersive virtual reality

    This paper focuses on developing and assessing a non-obtrusive and transformative method, based on virtual reality, to evaluate science communication projects in science centres. The method was tested using deep-sea cutting-edge scientific content. We applied a mixed design, with 72 adult participants randomly assigned to experimental conditions (with/without exhibition exposure). Results showed that the exhibition promoted a better understanding of science. The non-obtrusive measures on awareness and engagement were positively related with questions posed via questionnaire and interview. The study adds theoretical and empirical support to the design and implementation of non-obtrusive and transformative evaluation experiences in science exhibitions in science centres and museums.info:eu-repo/semantics/publishedVersio

    Paciente do sexo feminino de 63 anos, melanoderma, ingressou em hospital público se queixando de prurido e secreção nos glúteos por aproximadamente um mês, após visita em área rural. A mesma relatou que fazia uso de antibiótico pomada recomendado para tratamento de furúnculo. Ao exame clínico observou-se duas lesões hiperêmicas e com exsudato purulento, diagnosticadas como miíase furunculóide. Foi removida uma larva viva de Dermatobia hominis de cada lesão, com auxílio de curativo oclusivo com vaselina e pinça. Três doenças devem ser diferenciadas: furúnculo, miíase furunculóide, (causada por D. hominis) e miíase tecidual (causada por Cochliomyia hominivorax devido à extensa destruição tecidual causada por esta última. A 63 year old black female was admitted in a public hospital complaining of itching and secretion in the gluteus for approximately one month after a trip to a rural area. The patient reported using antibiotic ointment for furuncle treatment. At the clinical examination, two hyperemic lesions showing purulent exudate were observed, and were diagnosed as furunculoid myiasis. One Dermatobia hominis larva was removed from each lesion, by means of occlusion using petroleum jelly and tweezers. Three diseasesshould be differentiated when dealing with this kind of occurrence: furuncles, furunculoid myiasis (caused by D. hominis and tissue myiasis (caused by Cochliomyia hominivorax) due to the extensive tissue destruction caused by the latter.

    Children’s right to participate: The Lundy model applied to early childhood education and care

    Children have the right to express their views in all matters affecting them, and to have them considered and given due weight. Children’s participation is most meaningful when rooted in children’s everyday lives, and its promotion should be encouraged from the youngest ages, especially in early childhood education and care (ecec). In this paper we apply the Lundy model of participation, widely used in policy, practice and professional development initiatives, to the ecec context. Based on examples provided by ecec professionals from Belgium, Greece, Poland, and Portugal, we illustrate the implementation of the elements of space, voice, audience and influence, proposed by the Lundy model. We also discuss the interrelations among these elements and the need for organisational and contextual support to enhance children’s participation. This paper adds to existing literature, highlighting theoretical and practical issues associated with the promotion of children’s right to participate in ecec.info:eu-repo/semantics/acceptedVersio

    Observation of an Excited Bc+ State

    Using pp collision data corresponding to an integrated luminosity of 8.5 fb-1 recorded by the LHCb experiment at center-of-mass energies of s=7, 8, and 13 TeV, the observation of an excited Bc+ state in the Bc+π+π- invariant-mass spectrum is reported. The observed peak has a mass of 6841.2±0.6(stat)±0.1(syst)±0.8(Bc+) MeV/c2, where the last uncertainty is due to the limited knowledge of the Bc+ mass. It is consistent with expectations of the Bc∗(2S31)+ state reconstructed without the low-energy photon from the Bc∗(1S31)+→Bc+γ decay following Bc∗(2S31)+→Bc∗(1S31)+π+π-. A second state is seen with a global (local) statistical significance of 2.2σ (3.2σ) and a mass of 6872.1±1.3(stat)±0.1(syst)±0.8(Bc+) MeV/c2, and is consistent with the Bc(2S10)+ state. These mass measurements are the most precise to date

    The Portuguese Society of Rheumatology position paper on the use of biosimilars

    Get PDF
    Biotechnological drugs have become a fundamental resource for the treatment of rheumatic patients. Patent expiry of some of these drugs created the opportunity for biopharmaceutical manufacturers to develop biosimilar drugs intended to be as efficacious as the originator product but with a lower cost to healthcare systems. Due to the complex manufacturing process and highly intricate structure of biologicals, a biosimilar can never be an exact copy of its reference product. Consequently, regulatory authorities issued strict preclinical and clinical guidelines to ensure safety and efficacy equivalence and, in September 2013, the biosimilar of infliximab was the first biosimilar monoclonal antibody to be authorized for use in the European Union. The current document is a position statement of the "Sociedade Portuguesa de Reumatologia" (Portuguese Society of Rheumatology) on the use of biosimilar drugs in rheumatic diseases. Two systematic literature reviews were performed, one concerning clinical trials and the other one concerning international position papers on biosimilars. The results were presented and discussed in a national meeting and a final position document was discussed, written and approved by Portuguese rheumatologists. Briefly, this position statement is contrary to automatic substitution of the originator by the biosimilar, defends either a different INN or the prescription by brand name, supports that switching between biosimilars and the originator molecule should be done after at least 6 months of treatment and based on the attending physician decision and after adequate patient information, recommends the registration of all biosimilar treated patients in Reuma.pt for efficacy, safety and immunogenicity surveillance, following the strategy already ongoing for originators, and opposes to extrapolation of indications approved to the originator to completely different diseases and/or age groups without adequate pre-clinical, safety or efficacy data.info:eu-repo/semantics/publishedVersio
