Strontium and neodymium isotopic variations in early Archean gneisses affected by middle to late Archean high-grade metamorphic processes: West Greenland and Labrador

Relicts of continental crust formed more than 3400 Ma ago are preserved fortuitously in most cratons. The cratons provide the most direct information about crust and mantle evolutionary processes during the first billion years of Earth history. In view of their polymetamorphic character, these terrains are commonly affected by subsequent tectonothermal events. Hence, their isotope systematics may be severely disturbed as a result of bulk chemical change or local isotopic homogenization. This leads to equivocal age and source information for different components within these terrains. The Sr and Nd isotopic data are presented for early Archean gneisses from the North Atlantic Craton in west Greenland and northern Labrador which were affected by younger metamorphic events

Temperature dependence of the ohmic conductivity and activation energy of Pb1+y(Zr0.3Ti0.7)O3 thin films

The ohmic conductivity of the sol-gel derived Pb1+y(Zr0.3Ti0.7)O3 thin films (with the excess lead y=0.0 to 0.4) are investigated using low frequency small signal alternate current (AC) and direct current (DC) methods. Its temperature dependence shows two activation energies of 0.26 and 0.12 eV depending on temperature range and excess Pb levels. The former is associated with Pb3+ acceptor centers, while the latter could be due to a different defect level yet to be identified.Comment: 13 pages, 3 figures, PostScript.

The Wool ComfortMeter and the Wool HandleMeter, new opportunities for wool

Two instruments have been developed by the Sheep CRC that provide the tools for a new standard in comfort and handle for the next generation of next-to-skin wool knitwear. The Wool ComfortMeter and Wool HandleMeter provide a rapid, accurate and objective measure of two important characteristics of wool knitwear that are currently determined by subjective assessment. The Wool HandleMeter allows the prediction of a set of handle attribute values that can quantify the hand feel of a lightweight jersey fabric. The instrument uses the principle of pushing a fabric sample through a ring. The force displacement curve associated with the fabric test is characterised and used to define each fabric. These values were then compared to the average handle values, as determined by a group of experts, of a large set of lightweight knitted fabrics. Algorithms were developed that enable the instrument to more accurately predict each of seven handle attributes than an individual expert. The Wool ComfortMeter provides a measure of the fibres that are protruding from the surface of the fabric that are responsible for the itchy sensation caused by some knitwear. The results from the instrument have been compared to the results from extensive wearer trials to provide an understanding of the relationship between the instrument value and the comfort perceptions of wearers. The results have shown a very clear relationship between the instrument and wearer trials

Designing for Reuse in an Industrial Internet of Things Monitoring Application

Abstract The Internet of Things (IoT) continues to experience rapid growth, and its influence is extending into previously unreached domains. However, some of these new domains impose specific limitations that complicate the design and implementation of IoT systems. Examples of such limitations are the exclusion of specific protocols, restrictions on the types of data that can be collected, requirements about what information can be transmitted to the public and controls around how that communication occurs. Capturing, representing and designing for these limitations as well as reuse is essential for the quick and successful deployment of such projects. In this paper, we present a case study of an IoT human in the loop monitoring system built for use within an industrial setting. We report our experiences with both designing the first deployment of the system as well as designing variation points into the software architecture to account for future iterations and deployment into other environments

Intensive Learning Centre Concept Report

NSW Corrective Services (CSNSW) engaged the Designing Out Crime (DOC) research centre to research and develop design concept for the development, design and construction of Intensive Learning Centres (ILC) for their correctional facilities. DOC compiled a UTS design team with expertise in architecture, industrial design, design thinking, environmental psychology and correctional environments. The central task for the design team is to respond to the design brief with a design concept that embodies the program principles and can be delivered by corrective services within the project parameters

What is eHealth (6)? Development of a Conceptual Model for eHealth: Qualitative Study with Key Informants

©Tim Shaw, Deborah McGregor, Melissa Brunner, Melanie Keep, Anna Janssen, Stewart Barnet. Originally published in the Journal of Medical Internet Research (http://www.jmir.org), 24.10.2017. BACKGROUND: Despite rapid growth in eHealth research, there remains a lack of consistency in defining and using terms related to eHealth. More widely cited definitions provide broad understanding of eHealth but lack sufficient conceptual clarity to operationalize eHealth and enable its implementation in health care practice, research, education, and policy. Definitions that are more detailed are often context or discipline specific, limiting ease of translation of these definitions across the breadth of eHealth perspectives and situations. A conceptual model of eHealth that adequately captures its complexity and potential overlaps is required. This model must also be sufficiently detailed to enable eHealth operationalization and hypothesis testing.OBJECTIVE: This study aimed to develop a conceptual practice-based model of eHealth to support health professionals in applying eHealth to their particular professional or discipline contexts.METHODS: We conducted semistructured interviews with key informants (N=25) from organizations involved in health care delivery, research, education, practice, governance, and policy to explore their perspectives on and experiences with eHealth. We used purposeful sampling for maximum diversity. Interviews were coded and thematically analyzed for emergent domains.RESULTS: Thematic analyses revealed 3 prominent but overlapping domains of eHealth: (1) health in our hands (using eHealth technologies to monitor, track, and inform health), (2) interacting for health (using digital technologies to enable health communication among practitioners and between health professionals and clients or patients), and (3) data enabling health (collecting, managing, and using health data). These domains formed a model of eHealth that addresses the need for clear definitions and a taxonomy of eHealth while acknowledging the fluidity of this area and the strengths of initiatives that span multiple eHealth domains.CONCLUSIONS: This model extends current understanding of eHealth by providing clearly defined domains of eHealth while highlighting the benefits of using digital technologies in ways that cross several domains. It provides the depth of perspectives and examples of eHealth use that are lacking in previous research. On the basis of this model, we suggest that eHealth initiatives that are most impactful would include elements from all 3 domains

Reframing the purpose, practice and place of juvenile detention in the Northern Territory.

It is clear that for real and lasting change to occur and to be able to create a respectable youth justice system in the NT, a thorough re-evaluation of the purpose, practice and place of detention is required. This submission supports such a re-evaluation, by presenting some findings from our collective experience and expertise related to detention design and research. We provide a summary of literature that helps build an understanding of the current state of dysfunction in the juvenile detention system. Then, drawing on our own experiences working in this context, we suggest a new way of framing juvenile detention that allows and encourages young people to flourish. We offer this perspective for the Commission’s consideration to illustrate that there are many opportunities through which the NT juvenile justice system could be reshaped, rather than to provide definitive or exhaustive conclusions about the way that this should be done
