A review of Australian approaches for monitoring, assessing and reporting estuarine condition: III. Evaluation against international best practice and recommendations for the future

In this final component of a three-part review, we present a national synthesis and evaluation of approaches for monitoring, assessing and reporting estuarine condition across Australia. Progress is evaluated against objective criteria that together provide a model of international best practice. We critically assess the limitations, inconsistencies and gaps that are evident across Australian jurisdictions, and identify common obstacles to future progress. Major strengths and successes are also highlighted, together with specific examples of best practice from around Australia that are transferable to other States and beyond. Significant obstacles to greater national coordination of monitoring and reporting practices include inconsistent spatial scales of management, pluralistic governance structures and the lack of any overarching legislation. Nonetheless, many perceptible advances have been made over the last decade across Australia in estuarine monitoring and health assessment, and there is great potential for further progress. Finally, we provide a list of recommendations to address some of the most pressing limitations and gaps, and support improved future monitoring, assessment and reporting for Australian estuaries

A review of Australian approaches for monitoring, assessing and reporting estuarine condition: I. International context and evaluation criteria

© 2016 Elsevier Ltd Given the immeasurable value of estuaries and their severe and growing pressures, sound understanding and reporting of estuarine condition is essential for their effective management and sustainable development. In light of this, we aim to provide a timely and comprehensive three-part review of the approaches currently employed for monitoring, assessing and reporting estuarine condition, focussing on Australian systems. Here, in Part 1, we establish the national and international context of our review and define globally-relevant evaluation criteria against which to assess Australian progress. We achieve this by examining effective monitoring, assessment and reporting programs from around the world and characterising ‘best practice’. We then highlight the Australian historical context and consider recent policies, frameworks, guidelines and legislation relating to the monitoring and reporting of estuarine condition nationwide

First description of myxozoans from Syria: novel records of hexactinomyxon, triactinomyxon and endocapsa actinospore types

Oligochaete worms collected in late March and early April 2005 from 3 freshwater biotopes in Syria were surveyed over an 11 wk period for myxosporean parasites (Myxozoa). Three types of novel actinospore stages were identified from 1 host species, Psammoryctides albicola. A hexactinomyxon was found in 6 P. albicola (7.5%) collected from a branch of the River Orontes, north of the city of Hama. A triactinomyxon and an endocapsa were found in single P. albicola specimens from the Al-Thaurah region of the Euphrates River (Lake Assad). No oligochaetes collected from Al-Ghab fish farm (Orontes region) released actinospores during the observation period. The present study is the first description of myxosporeans, including actinospore stages, from Syria. The 3 types described herein differ morphologically and molecularly (18S rDNA) from published records

Probabilistic soil moisture projections to assess Great Britain's future clay-related subsidence hazard

Clay-related subsidence is Great Britain’s (GB) most damaging soil-related geohazard, costing the economy up to £500 million per annum. Soil-related geohazard models based on mineralogy and potential soil moisture deficit (PSMD) derived from historic weather data have been used in risk management since the 1990s. United Kingdom Climate Projections (UKCP09) suggest that regions of GB will experience hotter, drier summers and warmer, wetter winters through to 2050. As a result, PSMD fluctuations are expected to increase, exacerbating the shrinkage and swelling of clay soils. A forward-looking approach is now required to mitigate the impacts of future climate on GB’s built environment. We present a framework for incorporating probabilistic projections of PSMD, derived from a version of the UKCP09 stochastic weather generator, into a clay subsidence model. This provides a novel, national-scale thematic model of the likelihood of clay-related subsidence, related to the top 1-1.5m soil layer, for three time periods; baseline (1961-1990), 2030 (2020-2049) and 2050 (2040-2069). Results indicate that much of GB, with the exception of upland areas, will witness significantly higher PSMDs through to the 2050’s. As a result, areas with swelling clay soils will be subject to proportionately increased subsidence hazard. South-east England will likely incur the highest hazard exposure to clay-related subsidence through to 2050. Potential impacts include increased incidence of property foundation subsidence, alongside deterioration and increased failure rates of GB’s infrastructure networks. Future clay-subsidence hazard scenarios provide benefit to many sectors, including: finance, central and local government, residential property markets, utilities and infrastructure operators.EPSR

Soil geohazard mapping for improved asset management of UK local roads

Unclassified roads comprise 60% of the road network in the United Kingdom (UK). The resilience of this locally important network is declining. It is considered by the Institution of Civil Engineers to be “at risk” and is ranked 26th in the world. Many factors contribute to the degradation and ultimate failure of particular road sections. However, several UK local authorities have identified that in drought conditions, road sections founded upon shrink–swell susceptible clay soils undergo significant deterioration compared with sections on non-susceptible soils. This arises from the local road network having little, if any, structural foundations. Consequently, droughts in East Anglia have resulted in millions of pounds of damage, leading authorities to seek emergency governmental funding. This paper assesses the use of soil-related geohazard assessments in providing soil-informed maintenance strategies for the asset management of the locally important road network of the UK. A case study draws upon the UK administrative county of Lincolnshire, where road assessment data have been analysed against mapped clay-subsidence risk. This reveals a statistically significant relationship between road condition and susceptible clay soils. Furthermore, incorporation of UKCP09 future climate projections within the geohazard models has highlighted roads likely to be at future risk of clay-related subsidence

Enhanced visualization of the flat landscape of the Cambridgeshire Fenlands

The Fenlands of East Anglia, England, represent a subtle landscape, where topographic highs rarely exceed 30 m above sea level. However, the fens represent an almost full sequence of Quaternary deposits which, together with islands of Cretaceous and Jurassic outcrops, make the area of geological importance. This feature discusses the advantages of using 3D visualization coupled with high-resolution topographical data, over traditional 2D techniques, when undertaking an analysis of the landscape. Conclusions suggest that the use of 3D visualization will result in a higher level of engagement, particularly when communicating geological information to a wider public

Against Prevailing Currents: The History of Them Days Magazine in Labrador

For more than four decades, Them Days magazine has portrayed Labradorians in their own words through publishing a quarterly periodical and multiple books about Labrador as well as creating a public archive. This article will focus on the historical aspects of the magazine’s inception and the challenges its creators faced as they built a storehouse of Labrador narratives that would represent the cultures that make Labrador unique and document a way of life considered to be in precipitous decline. It will also discuss how individuals, peoples, and even magazines must continually negotiate their identities through power relations in a settler-colonial state.Depuis plus de quatre décennies, la revue Them Days dépeint les gens du Labrador dans leurs propres mots grâce à la publication d’un numéro trimestriel et de nombreux livres sur le Labrador, ainsi qu’à la création d’un fonds d’archives publiques. Cet article s’intéresse principalement aux aspects historiques de la fondation de la revue et aux défis que ses fondateurs ont dû relever pour construire un stock de récits du Labrador qui représenteraient les cultures qui font l’originalité du Labrador et qui documenteraient un mode de vie considéré comme en déclin rapide. Il examine également comment les individus, les peuples et même les revues doivent continuellement négocier leur identité à travers des rapports de force dans un État de peuplement colonial

Fifty Years of Innovation in Plastic Surgery

© 2016 The Korean Society of Plastic and Reconstructive Surgeons.Background Innovation has molded the current landscape of plastic surgery. However, documentation of this process only exists scattered throughout the literature as individual articles. The few attempts made to profile innovation in plastic surgery have been narrative, and therefore qualitative and inherently biased. Through the implementation of a novel innovation metric, this work aims to identify and characterise the most prevalent innovations in plastic surgery over the last 50 years. Methods Patents and publications related to plastic surgery (1960 to 2010) were retrieved from patent and MEDLINE databases, respectively. The most active patent codes were identified and grouped into technology areas, which were subsequently plotted graphically against publication data. Expert-derived technologies outside of the top performing patents areas were additionally explored. Results Between 1960 and 2010, 4,651 patents and 43,118 publications related to plastic surgery were identified. The most active patent codes were grouped under reconstructive prostheses, implants, instruments, non-invasive techniques, and tissue engineering. Of these areas and other expert-derived technologies, those currently undergoing growth include surgical instruments, implants, non-invasive practices, transplantation and breast surgery. Innovations related to microvascular surgery, liposuction, tissue engineering, lasers and prostheses have all plateaued. Conclusions The application of a novel metric for evaluating innovation quantitatively outlines the natural history of technologies fundamental to the evolution of plastic surgery. Analysis of current innovation trends provides some insight into which technology domains are the most active
