O engenheiro Adriano Monteiro e a utilização do ferro na reconversão e refuncionalização de espaços em Évora: o caso do Palácio D. Manuel e dos Paços do Concelho

Resumo A partir da segunda metade do século XIX e XX assistiu-se à introdução de novos materiais, como o ferro fundido, o aço e o vidro, na remodelação ou construção de edifícios que procuravam dar resposta às novas necessidades de gestão urbana e de criação de espaços de lazer e sociabilidade. Nestas intervenções, que ficaram marcadas pela arquitectura do ferro, os engenheiros, grupo profissional detentor de competências técnicas que os habilitavam a trabalhar com estes materiais, tiveram um papel determinante. Na cidade de Évora a ligação entre a utilização de novos materiais e os engenheiros, é visível no papel que o Engenheiro Adriano Monteiro teve na reconversão do Palácio D. Manuel e na remodelação do edifício dos Paços do Concelho. Palavras-chave: Engenheiro, Arquitectura do Ferro, Évora, Palácio D. Manuel, Paços do Concelho Abstract From the second half of the nineteenth century onwards, there was the introduction of new materials, such as cast iron, steel and glass, in the remodeling or in the construction of buildings that sought to satisfy the new needs of urban management and the creation of leisure spaces and sociability. In these interventions that were marked by the iron architecture, the engineers, a professional group with technical skills that enabled them to work with these materials, played a decisive role. In the city of Évora this link between the utilization of new materials and engineers, is visible in the role that engineer Adriano Monteiro had in the conversion of the D. Manuel Palace and in the remodeling of the Town Hall building. Keywords: Engineers, Iron Architecture, Évora, D. Manuel Palace, City Hall

BETWEEN IMAGES AND SCOURGES: THE REGIONAL CABLE VERDEAN MANUEL LOPES

This article aims to analyze the work The flagellates East Wind (1959), Cape Verdean writer Manuel Lopes, highlighting their contribution to the development of Cape Verde literature, from a regionalist perspective. In this work, Manuel Lopes introduces the reader to the hard reality that the panel are subjected the inhabitants of St. Anthony, victims of insular confinement and natural phenomena that afflict the region. Thus, this analysis understand regionalism as a timeless current, as Ligia Chiappini (1995), which does not exclude the universalism of the work and seek to identify the specifics of the landscape, the structure and organization of the Cape Verdean society, customs, cuisine, music, way of speaking as a translation for the construction of national identity. Therefore, we will use as theorists subsidies Manuel Ferreira (1997), Daniel Spínola (1998), Simone Caputo Gomes (2008) (2015), João Paulo Madeira (2014), Maria Aparecida Santilli (1985), Maria Nazareth Soares Fonseca e Terezinha Taborna Moreira (2014), among others.

A POÉTICA DO PENSAMENTO INFANTIL NA OBRA DE JOÃO GUIMARÃES ROSA

O presente estudo apresenta algumas reflexões acerca do pensamento infantil e seus aspectos poéticos. Para tanto, inspiramo-nos em um conto de João Guimarães Rosa, extraído do livro Primeiras estórias, intitulado “A partida do audaz navegante”. A protagonista do conto é uma criança cujo olhar poético é traduzido em um discurso também poético e polifônico, rico em desvios sintáticos e em criações vocabulares insólitas e instigantes. O conto enfocado revela a presença de um olhar lírico e filosófico sobre as situações cotidianas, que rompem com os paradigmas tradicionais e trazem à tona o imprevisível. A protagonista da história em questão apreende e compreende a realidade pelo viés poético, criando, deste modo, revoluções discursivas poéticas para as situações cotidianas. E é justamente este olhar que a faz ver novas possibilidades onde ninguém consegue ver. Esta forma singular e imprevisível de produzir os discursos por parte da criança na obra de Guimarães Rosa é similar aos gestos discursivos da criança de um modo geral, que, no presente estudo, relacionamos aos do poeta. As surpreendentes desacomodações sintático-gramaticais presentes nas falas da protagonista, longe de serem encaradas como erros gramaticais, fazem-nos refletir sobre o vigor do discurso infantil e as suas idiossincrasias, reflexos de um universo lírico e criativo. O pensamento mágico da criança e sua perplexidade diante do universo que a cerca se expressam por meio de um discurso também mágico e insólito, como o dos poetas. Deste modo, por meio de um diálogo com o filósofo Bachelard, em sua Poética do devaneio, propomos, neste estudo, uma apreciação do discurso infantil no que ele possui de mágico e original, fruto de devaneios criativos, desamarrados dos condicionamentos da linguagem mecânica e instrumentalizada.

O PENSAMENTO DIALÉTICO DE DANTE MOREIRA LEITE E SUA CRÍTICA À IDEOLOGIA DO CARÁTER NACIONAL BRASILEIRO

Este artigo apresenta uma síntese do pensamento de Dante Moreira Leite (1927-1976) acerca da identidade nacional. Suas análises demonstram as contradições das formulações sobre o caráter nacional, ao denunciar as tentativas de generalizar as características particulares de um grupo ou classe de uma época, como se fossem de toda uma nação. Moreira Leite mostra como as formulações do caráter nacional se tornaram pseudocientíficos e se constituem em ideologias conservadoras ou burguesas, deformando realidades no intuito de fortalecer e manter o status quo. Neste sentido, Dante mostra a fragilidade de qualquer estereótipo que se aventura pelos caminhos das raízes do caráter nacional, utilizando-se de textos da literatura. Pontua o cientificismo de Silvio Romero, a originalidade de Euclides da Cunha e de numerosos outros autores, como Afonso Celso, Nina Rodrigues, Manuel Bonfim, Gilberto Freyre, Sérgio Buarque de Holanda e Caio Prado Júnior. A partir dessas referências, conclui que as ideologias existentes ligadas à definição do caráter nacional brasileiro não representam a autêntica tomada de consciência de uma nação, mas obstáculos para que um povo se torne livre de preconceitos.

Future directions and perspectives for problem solving research and curriculum development

Since the 1960s, numerous studies on problem solving have revealed the complexity of the domain and the difficulty in translating research findings into practice. The literature suggests that the impact of problem solving research on the mathematics curriculum has been limited. Furthermore, our accumulation of knowledge on the teaching of problem solving is lagging. In this first discussion paper we initially present a sketch of 50 years of research on mathematical problem solving. We then consider some factors that have held back problem solving research over the past decades and offer some directions for how we might advance the field. We stress the urgent need to take into account the nature of problem solving in various arenas of today’s world and to accordingly modernize our perspectives on the teaching and learning of problem solving and of mathematical content through problem solving. Substantive theory development is also long overdue—we show how new perspectives on the development of problem solving expertise can contribute to theory development in guiding the design of worthwhile learning activities. In particular, we explore a models and modeling perspective as an alternative to existing views on problem solving.

Methodologies for investigating relationships between concept development and the development of problem solving abilities

This paper is the second in a pair that Lesh, English, and Fennewald will be presenting at ICME TSG 19 on Problem Solving in Mathematics Education. The first paper describes three shortcomings of past research on mathematical problem solving. The first shortcoming can be seen in the fact that knowledge has not accumulated – in fact it has atrophied significantly during the past decade. Unsuccessful theories continue to be recycled and embellished. One reason for this is that researchers generally have failed to develop research tools needed to reliably observe, document, and assess the development of concepts and abilities that they claim to be important. The second shortcoming is that existing theories and research have failed to make it clear how concept development (or the development of basic skills) is related to the development of problem solving abilities – especially when attention is shifted beyond word problems found in school to the kind of problems found outside of school, where the requisite skills and even the questions to be asked might not be known in advance. The third shortcoming has to do with inherent weaknesses in observational studies and teaching experiments – and the assumption that a single grand theory should be able to describe all of the conceptual systems, instructional systems, and assessment systems that strongly molded and shaped by the same theoretical perspectives that are being used to develop them. Therefore, this paper will describe theoretical perspectives and methodological tools that are proving to be effective to combat the preceding kinds or shortcomings. We refer to our theoretical framework as models & modeling perspectives (MMP) on problem solving (Lesh & Doerr, 2003), learning, and teaching. One of the main methodologies of MMP is called multi-tier design studies (MTD).

In Response: "Oral versus IV treatment for catheter-related bloodstream infections - by Burke A. Cunha"

In his letter Cunha suggests that oral antibiotic therapy is safer and less expensive than intravenous therapy via central venous catheters (CVCs) (1). The implication is that costs will fall and increased health benefits will be enjoyed resulting in a gain in efficiency within the healthcare system. CVCs are often used in critically ill patients to deliver antimicrobial therapy, but expose patients to a risk of catheter-related bloodstream infection (CRBSI). Our current knowledge about the efficiency (i.e. costeffectiveness) of allocating resources toward interventions that prevent CRBSI in patients requiring a CVC has already been reviewed (2). If for some patient groups antimicrobial therapy can be delivered orally, instead of through a CVC, then the costs and benefits of this alternate strategy should be evaluated...

Integrin-linked kinase as a target for ERG-mediated invasive properties in prostate cancer models

Approximately half of prostate cancers (PCa) carry TMPRSS2-ERG translocations; however, the clinical impact of this genomic alteration remains enigmatic. Expression of v-ets erythroblastosis virus E26 oncogene like (avian) gene (ERG) promotes prostatic epithelial dysplasia in transgenic mice and acquisition of epithelial-to-mesenchymal transition (EMT) characteristics in human prostatic epithelial cells (PrECs). To explore whether ERG-induced EMT in PrECs was associated with therapeutically targetable transformation characteristics, we established stable populations of BPH-1, PNT1B and RWPE-1 immortalized human PrEC lines that constitutively express flag-tagged ERG3 (fERG). All fERG-expressing populations exhibited characteristics of in vitro and in vivo transformation. Microarray analysis revealed >2000 commonly dysregulated genes in the fERG-PrEC lines. Functional analysis revealed evidence that fERG cells underwent EMT and acquired invasive characteristics. The fERG-induced EMT transcript signature was exemplified by suppressed expression of E-cadherin and keratins 5, 8, 14 and 18; elevated expression of N-cadherin, N-cadherin 2 and vimentin, and of the EMT transcriptional regulators Snail, Zeb1 and Zeb2, and lymphoid enhancer-binding factor-1 (LEF-1). In BPH-1 and RWPE-1-fERG cells, fERG expression is correlated with increased expression of integrin-linked kinase (ILK) and its downstream effectors Snail and LEF-1. Interfering RNA suppression of ERG decreased expression of ILK, Snail and LEF-1, whereas small interfering RNA suppression of ILK did not alter fERG expression. Interfering RNA suppression of ERG or ILK impaired fERG-PrEC Matrigel invasion. Treating fERG-BPH-1 cells with the small molecule ILK inhibitor, QLT-0267, resulted in dose-dependent suppression of Snail and LEF-1 expression, Matrigel invasion and reversion of anchorage-independent growth. These results suggest that ILK is a therapeutically targetable mediator of ERG-induced EMT and transformation in PCa.

Taxonomic review of the chironomid genus Cricotopus v.d. Wulp (Diptera: Chironomidae) from Australia : keys to males, females, pupae and larvae, description of ten new species and comments on Paratrichocladius Santos Abreu

The Australian species of the Orthocladiinae genus Cricotopus Wulp (Diptera: Chironomidae) are revised for larval, pupal, adult male and female life stages. Eleven species, ten of which are new, are recognised and keyed, namely Cricotopus acornis Drayson & Cranston sp. nov., Cricotopus albitarsis Hergstrom sp. nov., Cricotopus annuliventris (Skuse), Cricotopus brevicornis Drayson & Cranston sp. nov., Cricotopus conicornis Drayson & Cranston sp. nov., Cricotopus hillmani Drayson & Cranston, sp. nov., Cricotopus howensis Cranston sp. nov., Cricotopus parbicinctus Hergstrom sp. nov., Cricotopus tasmania Drayson & Cranston sp. nov., Cricotopus varicornis Drayson & Cranston sp. nov. and Cricotopus wangi Cranston & Krosch sp. nov. Using data from this study, we consider the wider utility of morphological and molecular diagnostic tools in untangling species diversity in the Chironomidae. Morphological support for distinguishing Cricotopus from Paratrichocladius Santo-Abreu in larval and pupal stages appears lacking for Australian taxa and brief notes are provided concerning this matter.

Drug administration guides in dysphagia

Aim: The aim of this evaluation was to evaluate the use of Individualised Medication Administration Guides (IMAGs) for patients with dysphagia on one stroke ward over a 6month period. Background: Patients with dysphagia (PWD) are more likely to suffer an administration error than patients without swallowing difficulties. To both standardise and improve medicines administration to patients with dysphagia I-MAGs were introduced on one stroke ward over a 6 month period. Methods: A software package supported with data on current national guidelines on the administration of medicines to PWD was designed by a specialised pharmacist in dysphagia to enable him to create individualised medication administration guides for patients with dysphagia which stated how each medicine should be optimally prepared and administered. On completion of the pilot service a questionnaire was given to all nurses, pharmacist and speech and language therapists who had experienced the I-MAGs. All the professionals received the same questionnaire but questions relevant only to their practice were added to the nurse’s questionnaire. Results: Of 26 Healthcare professionals (HCPs) approached, 19 returned completed questionnaires. Higher variability was found in the 13 responses from the nurse respondents than in the ones from the 3 pharmacist and the 3 SALTs. 8 (61%) of the nurses felt more confident in their practice when I-MAGs were in place. 10 (76%) of the nurses admitted that the guides could sometimes increase the time of the administration, but saw that it made practice safer. All the pharmacists considered the recommendations in the guides useful and all the respondents with the exception of one nurse (12:13) would like this service to continue. Conclusion: I-MAGs were well received on the ward and they support individualised care for patients with dysphagia. But the guides needed additional pharmacist input and greater nursing time. Research to determine the cost effectiveness of I-MAGs is needed.

Implementation of individualised medication administration guides for patients with dysphagia: Results from a pilot controlled trial

Introduction Patients with dysphagia (PWDs) have been shown to be four times more likely to suffer medication administration errors (MAEs).1 2 Individualised medication administration guides (I-MAGs) which outline how each formulation should be administered, have been developed to standardise medication administration by nurses on the ward and reduce the likelihood of errors. This pilot study aimed to determine the recruitment rates, estimate effect on errors and develop the intervention to design a future full scale randomised controlled trial to determine the costs and effects of I-MAG implementation. Ethical approval was granted by local ethics committee. Method Software was developed to enable I-MAG production (based on current best practice)3 4 for all PWDs on two care of the older person wards admitted during a six month period from January to July 2011. I-MAGs were attached to the medication administration record charts to be utilised by nurses when administering medicines. Staff training was provided for all staff on the intervention wards. Two care of the older person wards in the same hospital were used for control purposes. All patients with dysphagia were recruited for follow up purposes at discharge. Four ward rounds at each intervention and control ward were observed pre and post I-MAG implementation to determine the level of medication administration errors. NHS ethical approval for the study was obtained. Results 164 I-MAGs were provided for 75 patients with dysphagia (PWDs) in the two intervention wards. At discharge, 23 patients in the intervention wards and 7 patients in the control wards were approached for recruitment of which 17 (74%) & 5 (71.5%) respectively consented. Discussion Recruitment rates were low on discharge due to the dysphagia remitting during hospitalisation. The introduction of the I-MAG demonstrated no effect on the quality of administration on the intervention ward and interestingly practice improved on the control ward. The observation of medication rounds at least one month post I-MAG removal may have identified a reversal to normal practice and ideally observations should have been undertaken with I-MAGs in place. Identification of the reason for the improvement in the control ward is warranted.

Inability to swallow tablets is common and cause for concern

Inappropriate formulation choices in the administration of medication to elderly patients with dysphagia in nursing homes

Inappropriate food or medication texture in patients with dysphagia is the most significant risk factor for pneumonia. Dysphagia is prevalent within care homes for the older person as it is largely found in conditions associated with ageing. This study was designed to determine the appropriateness of medication formulation choices in elderly patients with dysphagia in care homes.
