Hierarchical modelling of timber reference properties using probabilistic methods: Maximum Likelihood Method, Bayesian Methods and Probability Networks

In recent decades, an increased interest has been evidenced in the research on multi-scale hierarchical modelling in the field of mechanics, and also in the field of wood products and timber engineering. One of the main motivations for hierar-chical modelling is to understand how properties, composition and structure at lower scale levels may influence and be used to predict the material properties on a macroscopic and structural engineering scale. This chapter presents the applicability of statistic and probabilistic methods, such as the Maximum Likelihood method and Bayesian methods, in the representation of timber’s mechanical properties and its inference accounting to prior information obtained in different importance scales. These methods allow to analyse distinct timber’s reference properties, such as density, bending stiffness and strength, and hierarchically consider information obtained through different non, semi or destructive tests. The basis and fundaments of the methods are described and also recommendations and limitations are discussed. The methods may be used in several contexts, however require an expert’s knowledge to assess the correct statistic fitting and define the correlation arrangement between properties.

Does the provision of full day care improve the quality of life for children and their parents

This study sought to explore and examine if the provision of full day care improves the quality of life for children and their parents. Owing to the effects of the Celtic Tiger, life in Ireland has changed considerably over the past five to ten years. Because of the booming economy there are now 60.8% of women employed in the workforce. This means many changes for children, parents and families. Findings in the literature review are based on international studies. The researcher utilised both qualitative and quantitative research methodologies for the study. She interviewed 31 respondents; 27 childcare managers; 3 politicians and the chairperson of a childcare committee. Furthermore, 325 questionnaires were completed in a survey by working parents in the statutory and voluntary sectors in and around Sligo town and in two childcare facilities in Letterkenny, Co. Donegal. Babies as young as 4 months are being cared for in childcare facilities from 6.45am until 6.pm daily, 5 days per week. Some children are spending up to 11 hours per day in childcare facilities. The study has not categorically concluded that full day care is either positive or negative for children. Childcare facilities are providing good quality childcare encompassing various services; however, 25 out of 27 childcare managers reported to the researcher that they would not leave their child in full day care. Parents are finding it difficult to manage work life balance. Health dominated quality of life issues. Two hundred and thirty five (235) parents reported being stressed. The study also found that 315 working parents feel that the government is not doing enough to support working parents. On a positive note, 241 parents said they are happy in general with the quality of life for them, their family and their children. In addition, the researcher has identified a number of recommendations for future changes in policy and further study.

Intervenção coronária percutânea utilizando Full Metal Jacket com stents farmacológicos: eventos cardíacos adversos maiores em um ano

FUNDAMENTO: O benefício clínico de intervenção coronária percutânea (ICP) para lesões coronárias longas é incerto; além disso, foram levantadas dúvidas questões sobre a sua segurança. OBJETIVO: Avaliar os preditores de eventos cardíacos adversos maiores (ECAM) associados à ICP utilizando Full Metal Jacket (FMJ), definido como a sobreposição de stents farmacológicos (SF) medindo >60 mm de comprimento, para lesões muito longas. MÉTODOS: Foram incluídos 136 pacientes consecutivos com lesões coronárias longas, requerendo FMJ em nosso cadastro de centro único. O desfecho primário incluiu a ocorrência combinada de todas as causas de morte, infarto do miocárdio (IM) e revascularização do vaso alvo (RVA). Variáveis demográficas, clínicas, angiográficas e de procedimento foram avaliadas por meio de análise de regressão de Cox para determinar os preditores independentes de desfecho. RESULTADOS: O comprimento médio do stent por lesão foi de 73,2 ± 12,3 mm e o diâmetro médio do vaso de referência foi de 2,9 ± 0,6 mm. O sucesso angiográfico foi de 96,3%. A ausência de ECAM foi de 94,9% em 30 dias e 85,3% em um ano. No acompanhamento de um ano, a taxa de mortalidade por todas as causas foi de 3,7% (1,5% por mortes cardíacas), a taxa de IM foi de 3,7%, e a incidência de trombose de stent (TS) definitiva ou provável foi de 2,9%. O gênero feminino [risco relativo (RR), 4,40; intervalo de confiança de 95% (IC), 1,81-10,66, p = 0,001) e ICP de artéria coronária não direita (RR, 3,49; p = 0,006; IC 95%, 1,42-8,59) foram preditores independentes de ECAM em um ano. A ausência de eventos adversos em um ano foi maior em pacientes com angina estável submetidos à ICP (RR, 0,33; IC 95% 0,13-0,80, p = 0,014). CONCLUSÕES: A ICP utilizando FMJ com SF para lesões muito longas foi eficaz, mas associada a uma alta taxa de TS em acompanhamento de um ano. No entanto, a taxa de mortalidade cardíaca, IM não relacionado a procedimento, e ECAM foi relativamente baixa. ICP de vaso coronário alvo, apresentação clínica, e gênero feminino são novos fatores clínicos contemporâneos que parecem apresentar efeitos adversos sobre o resultado da ICP utilizando FMJ para lesões longas.

1st National Accessiblity Plan 2004-2012: achieving equal opportunities and full participation through design for all

According to official statistics, disabled people in Spain number 3.5 million and make up 8.8% of the Spanish population. This group of people are increasingly being recognised as members of society with equal rights, and many of their demands are gradually being transformed into solutions that benefit society as a whole. One example is improved accessibility. Accessible built environments are more human and inclusive places, as well as being easier to get around. Improved accessibility is now recognised as a requirement shared by all members of society, although it is achieved thanks to the demands of disabled people and their representatives. The 1st National Accessibility Plan is a strategic framework for action aimed at ensuring that new products, services and built environments are designed to be accessible for as many people as possible (Design for All) and that existing ones are gradually duly adapted.
