Is the social agenda driving sustainable property development in Melbourne, Australia?

Purpose – Sustainable property development has increased in market share over the past two to three years globally and locally. This research aims to analyze the drivers and barriers to sustainable property development in Melbourne using the triple bottom line (TBL) theoretical framework. The TBL posits that sustainability has social, economic and environmental aspects to fulfil.

Design/methodology/approach – A questionnaire was sent out to 190 developers in Melbourne who promoted sustainable property development to ascertain their views about the drivers and barriers.

Findings – This research indicates that in the 2007 Melbourne market the drivers were social rather than economic. The data reveal that social reasons are considered more than economic arguments for incorporating sustainability into developments. The business case, or the economic drivers for sustainability alone do not convince developers.

Research limitations/implications – The questionnaire survey informed us about developers' views but not why they have these views. The sample was limited to Melbourne.

Practical implications – More developments are required for developers to become convinced of the benefits. The relatively low price of energy undermines the business case for sustainability in property here and needs to be fully costed.

Originality/value – This paper illustrates that whilst the theoretical framework cites three key areas for sustainability, the reality is that developers are currently driven by social and environmental factors primarily and the business case is not accepted by the majority of developers.

Evaluation of postgraduate critical care nursing students' attitudes to, and engagement with, Team-Based Learning: a descriptive study

The aim of this study was to evaluate postgraduate critical care nursing students' attitudes to, and engagement with, Team-Based Learning (TBL).

Developing professional attributes in critical care nurses using Team-Based Learning.

Australian nurses prepare for specialty practice by undertaking postgraduate theoretical and clinical education in partnership models between universities and hospitals. In our global healthcare system, nurses require advanced critical thinking and strong communication skills to provide safe, high quality patient care. Yet, few education programs focus on developing these skills. Team-Based Learning (TBL) is a specific educational strategy that encourages and rewards students to think critically and solve clinical problems individually and in teams. The aim of this study was to investigate critical care nursing students' perceptions and experiences of TBL after it was introduced into the second half of their postgraduate specialty course. Following Ethics Committee approval, thirty-two students were invited to participate in an extended response questionnaire on their perceptions of TBL as part of a larger study. Data were analyzed thematically. Postgraduate students perceived their professional growth was accelerated due to the skills and knowledge acquired through TBL. Four themes underpinned the development and accelerated acquisition of specialty nurse attributes due to TBL: Engagement, Learning Effectiveness, Critical Thinking, and Motivation to Participate. Team-Based Learning offered deep and satisfying learning experiences for students. The early acquisition of advanced critical thinking, teamwork and communication skills, and specialty practice knowledge empowered nurses to provide safe patient care with confidence.

A potential anti-corrosive ionic liquid coating for MG alloy AZ31 in simulated body fluids

Magnesium alloys are attractive materials for biomedical applications, due to their excellent biocompatibility. However, these alloys show fast corrosion rates in the body that limits their clinical applications. Low-toxic ionic liquid (IL) trimethyl(butyl)phosphonium diphenyl phosphate P1444dpp has been investigated to provide corrosion protection for magnesium alloy AZ31 in simulated body fluids (SBFs). This work reports a preliminary exploration of the influence of different treatment temperatures on the corrosion protection properties of IL films for the magnesium alloy AZ31 in SBFs. Results show that the IL treatment at room temperature did not bring significant improvement in the corrosion performance of the AZ31 in SBF. However, when the treatment temperature was increased to 75°C, the IL treatment resulted in a substantial reduction of the corrosion, in particular the reduction of localized pitting corrosion. The influence of ionic liquid treatment on the corrosion performance of the magnesium alloys AZ31 in SBFs has been investigated by electrochemical impedance spectroscopy (EIS) tests and immersion tests.

Viewing The Biggest Loser : modes of reception and reflexivity among obese people

This article builds on previous reception research and scholarship on makeover TV through an analysis of obese people's views of The Biggest Loser (TBL). TBL involves obese people competing to lose weight as personal trainers push them through dietary and physical activity regimes. We articulate four themes characterizing responses to TBL: “That's not reality,” “Public ownership and judgment of the fat body,” “The lure of the transformation,” and “A guilty pleasure.” We consider how these themes are reflected in participants' movement between mediated, discursive, transparent, and referential modes of reception. While some were adamant in their rejection of the program, others were ambivalent in accepting and identifying with the desire for weight loss but questioning TBL's aesthetic dimensions and moralizing undertones. We argue that the reflexivity of viewers complicates appraisals of TBL as governing at a distance and offer some alternative readings of the impact and appeal of the program.

Produção in vitro de embriões bovinos: utilização de diferentes fontes de gonadotrofinas na maturação dos oócitos

O presente trabalho foi conduzido com o objetivo de avaliar o efeito da utilização de diferentes fontes de gonadotrofinas para maturação in vitro dos oócitos bovinos fecundados e desenvolvidos in vitro sobre as taxas de clivagem (TC) e de blastocistos (TBL). Oócitos imaturos provenientes de ovários de vacas de abatedouro foram submetidos a maturação in vitro sob diferentes condições: meio TCM 199, acrescido de 10% de soro de vaca em estro (SVE), aditivos, hepes, NaHCO3, piruvato de sódio, antibióticos (meio B-199), 20 UI/mL de PMSG e 10 UI/mL de hCG (PMSG/hCG) ou meio B-199, acrescido de 5 mig/mL de FSH e 5 mig/mL de LH (FSH/LH). Seguidos 24 h de cultura a 38,5ºC em atmosfera com 5% de CO2, os oócitos maturos foram incubados com sêmen descongelado durante 18 a 21 horas. Após esse período, os oócitos foram transferidos para placas contendo microgotas de meio Ménezo suplementado com 10% de SVE e células epiteliais do oviduto bovino em suspensão, cobertas com óleo de silicone, os quais permaneceram em cultura por mais 9 dias. Os dados foram analisados pelo teste do Qui-quadrado. A TC e a TBL, para PMSG/hCG e FSH/LH, foram 60 e 13,9% e 61,2 e 10,6%, respectivamente. Não houve diferença entre os tratamentos com relação a TC ou a TBL. Esses resultados sugerem que ambas as fontes de gonadotrofinas podem ser utilizadas para maturação in vitro dos oócitos fecundados e desenvolvidos in vitro.

Investigando o campo magnético das estrelas análogas e gêmeas solares através da espectropolarimetria

This study proposes an observing program focused on the investigation of the stellar magnetism and dynamo evolution in cool active solar-like stars. More mainly in the solar analogs and twins. Observations of stars of our base were carried out with two spectropolarimeter (ESPaDOnS@CFHT and NARVAL@TBL). The analyse of stars in stage different allows an understanding of the dependence of magnetic activity on basic stellar parameters such as rotation, mass, age and depth of the convection zone. This study provides measures necessary for testing dynamo theories. The 65 targets for this project are solar type stars with mass spanning from 0:9 M=Mfi 1:075 solar masses and at different evolutionary stages. Our two main science objectives were, (i) To determine how the magnetic field evolved from the ZAMS to the TO (turn off) for stars with 0:9 M=Mfi 1:075; (ii) To determine the impact of convective depth and rotation on magnetic of cool stars of solar type. The main result from this study was the characterization of the dependence of magnetic field intensity as function of age, Rossby number and the convective zone deepening. This context, the availability of ESPaDOnS and NARVAL opens an exceptional possibility to study the magnetic properties of Sun-like stars by means of spectropolarimetric observations

Abordagem para o desenvolvimento de um etiquetador de alta acurácia para o Português do Brasil

A etiquetagem morfossintática é uma tarefa básica requerida por muitas aplicações de processamento de linguagem natural, tais como análise gramatical e tradução automática, e por aplicações de processamento de fala, por exemplo, síntese de fala. Essa tarefa consiste em etiquetar palavras em uma sentença com as suas categorias gramaticais. Apesar dessas aplicações requererem etiquetadores que demandem maior precisão, os etiquetadores do estado da arte ainda alcançam acurácia de 96 a 97%. Nesta tese, são investigados recursos de corpus e de software para o desenvolvimento de um etiquetador com acurácia superior à do estado da arte para o português brasileiro. Centrada em uma solução híbrida que combina etiquetagem probabilística com etiquetagem baseada em regras, a proposta de tese se concentra em um estudo exploratório sobre o método de etiquetagem, o tamanho, a qualidade, o conjunto de etiquetas e o gênero dos corpora de treinamento e teste, além de avaliar a desambiguização de palavras novas ou desconhecidas presentes nos textos a serem etiquetados. Quatro corpora foram usados nos experimentos: CETENFolha, Bosque CF 7.4, Mac-Morpho e Selva Científica. O modelo de etiquetagem proposto partiu do uso do método de aprendizado baseado em transformação(TBL) ao qual foram adicionadas três estratégias, combinadas em uma arquitetura que integra as saídas (textos etiquetados) de duas ferramentas de uso livre, o TreeTagger e o -TBL, com os módulos adicionados ao modelo. No modelo de etiquetador treinado com o corpus Mac-Morpho, de gênero jornalístico, foram obtidas taxas de acurácia de 98,05% na etiquetagem de textos do Mac-Morpho e 98,27% em textos do Bosque CF 7.4, ambos de gênero jornalístico. Avaliou-se também o desempenho do modelo de etiquetador híbrido proposto na etiquetagem de textos do corpus Selva Científica, de gênero científico. Foram identificadas necessidades de ajustes no etiquetador e nos corpora e, como resultado, foram alcançadas taxas de acurácia de 98,07% no Selva Científica, 98,06% no conjunto de teste do Mac-Morpho e 98,30% em textos do Bosque CF 7.4. Esses resultados são significativos, pois as taxas de acurácia alcançadas são superiores às do estado da arte, validando o modelo proposto em busca de um etiquetador morfossintático mais confiável.

Wild Boar and Red Deer Display High Prevalences of Tuberculosis-Like Lesions in Spain

We describe the distribution of tuberculosis-like lesions (TBL) in wild boar (Sus scrofa) and red deer (Cervus elaphus) in Spain. Animals with TBL were confirmed in 84.21% of mixed populations (n = 57) of red deer and wild boar and in 75% of populations of wild boar alone (n = 8) in central and southern Spain (core area). The prevalence of TBL declined towards the periphery of this region. In the core area, the prevalence ranged up to 100% in local populations of wild boar (mean estate prevalence 42.51%) and up to 50% in red deer (mean estate prevalence 13.70%). We carried out exploratory statistical analyses to describe the epidemiology of TBL in both species throughout the core area. Prevalence of TBL increased with age in both species. Wild boar and red deer mean TBL prevalence at the estate level were positively associated, and lesion scores were consistently higher in wild boars than in red deer. The wild boar prevalence of TBL in wild boar did not differ between populations that were or were not cohabiting with red deer. Amongst the wild boars with TBL, 61.19% presented generalized lesions, and the proportion of generalized cases was similar between sex and age classes. In red deer, 57.14% of TBL-positive individuals presented generalized lesions, and the percentage of generalized cases increased with age class, but did not differ between the sexes. These results highlight the potential importance of wild boar and red deer in the maintenance of tuberculosis in south central Spain.

Risk Factors Associated With the Prevalence of Tuberculosis-Like Lesions in Fenced Wild Boar and Red Deer in South Central Spain

In recent decades the management of large game mammals has become increasingly intensive in south central Spain (SCS), resulting in complex epidemiological scenarios for disease maintenance, and has probably impeded schemes to eradicate tuberculosis (TB) in domestic livestock. We conducted an analysis of risk factors which investigated associations between the pattern of tuberculosis-like lesions (TBL) in wild boar (Sus scrofa) and red deer (Cervus elaphus) across 19 hunting estates from SCS and an extensive set of variables related to game management, land use and habitat structure. The aggregation of wild boar at artificial watering sites was significantly associated with an increasing risk of detecting TBL in both species, which probably relates to enhanced opportunities for transmission. Aggregation of wild boar at feeding sites was also associated with increased risks of TBL in red deer. Hardwood Quercus spp. forest availability was marginally associated with an increased risk of TB in both species, whereas scrubland cover was associated with a reduced individual risk of TBL in the wild boar. It is concluded that management practices that encourage the aggregation of hosts, and some characteristics of Mediterranean habitats could increase the frequency and probability of both direct and indirect transmission of TB. These findings are of concern for both veterinary and public health authorities, and reveal tuberculosis itself as a potential limiting factor for the development and sustainability of such intensive game management systems in Spanish Mediterranean habitats.

A new information fusion method for land-use classification using high resolution satellite imagery

Satellite image classification involves designing and developing efficient image classifiers. With satellite image data and image analysis methods multiplying rapidly, selecting the right mix of data sources and data analysis approaches has become critical to the generation of quality land-use maps. In this study, a new postprocessing information fusion algorithm for the extraction and representation of land-use information based on high-resolution satellite imagery is presented. This approach can produce land-use maps with sharp interregional boundaries and homogeneous regions. The proposed approach is conducted in five steps. First, a GIS layer - ATKIS data - was used to generate two coarse homogeneous regions, i.e. urban and rural areas. Second, a thematic (class) map was generated by use of a hybrid spectral classifier combining Gaussian Maximum Likelihood algorithm (GML) and ISODATA classifier. Third, a probabilistic relaxation algorithm was performed on the thematic map, resulting in a smoothed thematic map. Fourth, edge detection and edge thinning techniques were used to generate a contour map with pixel-width interclass boundaries. Fifth, the contour map was superimposed on the thematic map by use of a region-growing algorithm with the contour map and the smoothed thematic map as two constraints. For the operation of the proposed method, a software package is developed using programming language C. This software package comprises the GML algorithm, a probabilistic relaxation algorithm, TBL edge detector, an edge thresholding algorithm, a fast parallel thinning algorithm, and a region-growing information fusion algorithm. The county of Landau of the State Rheinland-Pfalz, Germany was selected as a test site. The high-resolution IRS-1C imagery was used as the principal input data.

Using ground-penetrating radar, topography and classification of vegetation to model the sediment and active layer thickness in a periglacial lake catchment, Western Greenland, link to shapefiles

The geometries of a catchment constitute the basis for distributed physically based numerical modeling of different geoscientific disciplines. In this paper results from ground-penetrating radar (GPR) measurements, in terms of a 3D model of total sediment thickness and active layer thickness in a periglacial catchment in western Greenland, is presented. Using the topography, thickness and distribution of sediments is calculated. Vegetation classification and GPR measurements are used to scale active layer thickness from local measurements to catchment scale models. Annual maximum active layer thickness varies from 0.3 m in wetlands to 2.0 m in barren areas and areas of exposed bedrock. Maximum sediment thickness is estimated to be 12.3 m in the major valleys of the catchment. A method to correlate surface vegetation with active layer thickness is also presented. By using relatively simple methods, such as probing and vegetation classification, it is possible to upscale local point measurements to catchment scale models, in areas where the upper subsurface is relatively homogenous. The resulting spatial model of active layer thickness can be used in combination with the sediment model as a geometrical input to further studies of subsurface mass-transport and hydrological flow paths in the periglacial catchment through numerical modelling.

Indicadores para avaliação de efeitos de intervenções de saneamento básico: a questão da sustentabilidade

As intervenções de saneamento básico, ou seja, as obras para implantação ou ampliação de sistemas de abastecimento de água e de esgotamento sanitário têm sido relacionadas à redução das taxas de mortalidade infantil ocorrida no estado de São Paulo nas últimas décadas. De fato, a relação entre saneamento básico e saúde pública é antiga, principalmente no que se refere ao controle das doenças de veiculação hídrica. Entretanto, ela se mostra muito fraca, ou até nula, para regiões onde os índices de cobertura por redes de água e esgotos já se encontram em patamares acima da média nacional, como é o caso de grande parte dos municípios do estado de São Paulo. Uma abordagem do saneamento básico, sob o ponto de vista da complexidade de suas relações, considerando aspectos multidimensionais, faz-se necessária como forma de repensar o setor de forma mais ampla, fugindo do senso comum. O objetivo desta pesquisa foi identificar, analisar e descrever indicadores de sustentabilidade que pudessem estabelecer uma nova base para avaliação de efeitos de intervenções de saneamento básico, melhorando a determinação e acompanhamento dos impactos decorrentes, constituindo, então, uma matriz de indicadores específicos para a área, a partir da investigação dos conceitos de sustentabilidade e seus desdobramentos para o setor saneamento básico e o ambiente empresarial. Pesquisas em bases de dados públicas permitiram a identificação e seleção de indicadores multidimensionais para o saneamento, assim como a análise de correlação entre os indicadores selecionados possibilitou identificar possíveis benefícios de curto, médio e longo prazos, oriundos das intervenções de saneamento para os municípios do Vale do Ribeira. Utilizando modelos de organização de indicadores, como o Triple Bottom Line (TBL) e a matriz de indicadores FPSEEA, da Organização Mundial da Saúde (OMS), com algumas adaptações, foi possível agrupar os indicadores de forma a permitir uma visão integrada das dimensões da sustentabilidade e, dessa maneira, determinar que as intervenções de saneamento básico possuem relações sistêmicas com indicadores sociais, ambientais e econômicos, que possibilitem, a partir de sua execução, o estabelecimento de um círculo virtuoso para os municípios
