Existing urban meteorological networks have an important role to play as test beds for inexpensive and more sustainable measurement techniques that are now becoming possible in our increasingly smart cities. The Birmingham Urban Climate Laboratory (BUCL) is a near-real-time, high-resolution urban meteorological network (UMN) of automatic weather stations and inexpensive, nonstandard air temperature sensors. The network has recently been implemented with an initial focus on monitoring urban heat, infrastructure, and health applications. A number of UMNs exist worldwide; however, BUCL is novel in its density, the low-cost nature of the sensors, and the use of proprietary Wi-Fi networks. This paper provides an overview of the logistical aspects of implementing a UMN test bed at such a density, including selecting appropriate urban sites; testing and calibrating low-cost, nonstandard equipment; implementing strict quality-assurance/quality-control mechanisms (including metadata); and utilizing preexisting Wi-Fi networks to transmit data. Also included are visualizations of data collected by the network, including data from the July 2013 U.K. heatwave as well as highlighting potential applications. The paper is an open invitation to use the facility as a test bed for evaluating models and/or other nonstandard observation techniques such as those generated via crowdsourcing techniques.

This work describes the evaluation of several parameters for the preparation of a tuna fish candidate as a reference material (RM) in order to measure the total As mass fraction by slurry sampling graphite furnace atomic absorption spectrometry (SLS-GF AAS) and slurry sampling hydride generation atomic absorption spectrometry (SLS-HG AAS). The main parameters investigated were the homogeneity, analyte segregation and composition during material production. For candidate RM preparation, tuna fish was collected at a local market, cleaned, freeze-dried and treated using different procedures as follows: (1) ground in a cutting mill and separated in different particle sizes (2) ground in cryogenic mill. The mass fraction of As in the cryogenically ground sample was (4.77 +/- A 0.19) mu g g(-1) for SLS-GF AAS and (4.61 +/- A 0.34) mu g g(-1) for SLS-HG AAS. The accuracy of the procedures was checked with tuna fish certified reference material (BCR 627) with recoveries of 102 and 94% for SLS-GF AAS and SLS-HG AAS, respectively. The homogeneity factor was calculated for different pretreatment procedures and for particle sizes in the range of 500-150 mu g, indicating good homogeneity, except for raw fish. There was no observed analyte segregation and no losses, no contamination and no changes in the microdistribution of material during preparation.

Syfte: Att kartlägga vårdpersonalens kunskapsläge samt utbildningsfrekvens i hjärtlungräddning på ett länssjukhus i Mellansverige, samt beskriva följsamheten till att registrera behandlade hjärtstopp till det svenska hjärt-lungräddningsregistret. Metod: Enkätstudie med kvantitativ ansats bestående av 177 respondenter samt även som en retrospektiv observationsstudie. Huvudresultat: Enskilda personer svarade rätt på alla kunskapsfrågorna men som grupp fanns det brister i kunskapen i hjärtlungräddning. Då man jämförde vårdpersonalens kunskap påvisades att i fyra av sju kunskapsfrågor fanns en signifikant skillnad i kunskap mellan den vårdpersonal som har mer regelbunden utbildning, än den som har mindre. De som hade mer regelbunden utbildning hade flera rätt. En signifikant skillnad påvisades även beroende på när man hade haft sin senaste HLR-utbildning, där de som haft sin utbildning nyligen hade flera rätt. Följsamheten hos vårdpersonalen till att registrera patienter som behandlats för hjärtstopp på sjukhus till det svenska hjärt-lungräddningsregistret, kan sammanfattas med att det brister i rapporteringen. Konklusion: Det är viktigt att skapa förutsättningar för frekventa utbildningar till vårdpersonal för att öka kunskap och beredskap i hjärt- och lungräddning, vilket även kan ses som ett kvalitetssäkringsarbete. Ett förbättringsarbete är nödvändigt för att förbättra följsamheten till registreringen.

Single-page applications have historically been subject to strong market forces driving fast development and deployment in lieu of quality control and changeable code, which are important factors for maintainability. In this report we develop two functionally equivalent applications using AngularJS and React and compare their maintainability as defined by ISO/IEC 9126. AngularJS and React represent two distinct approaches to web development, with AngularJS being a general framework providing rich base functionality and React a small specialized library for efficient view rendering. The quality comparison was accomplished by calculating Maintainability Index for each application. Version control analysis was used to determine quality indicators during development and subsequent maintenance where new functionality was added in two steps.   The results show no major differences in maintainability in the initial applications. As more functionality is added the Maintainability Index decreases faster in the AngularJS application, indicating a steeper increase in complexity compared to the React application. Source code analysis reveals that changes in data flow requires significantly larger modifications of the AngularJS application due to its inherent architecture for data flow. We conclude that frameworks are useful when they facilitate development of known requirements but less so when applications and systems grow in size.

The use of outcomes as a tool for curriculum development has considerable currency in Australia. It is widely perceived as representing world's best practice (South Australia Department of Education, Training and Employment, 2000, foreword) and as providing an effective means for quality assurance and enhancement (Willis & Kissane, 1997). At a system level, these assumptions have been unquestioned and unexamined, and curriculum frameworks in all Australian States now consider themselves to be 'outcome-based'. Surprisingly, this results in little similarity between Australian State educational frameworks, and raises the question of what I really understood about the concept of an 'outcome'. This essay explores some definitions of the term and related concepts of 'standards' and 'benchmarks'. The latter terms have less currency in Australia but can be shown to more accurately describe much of what we consider to be outcomes. The issue is not a semantic one, but goes to the very heart of our intentions in specifying learning outcomes. The indiscriminate use of the term 'outcome' has largely devalued it to the point that there is little real understanding and little debate about the efficacy of outcome setting as the primary process in curriculum production in Australia.

This article undertakes a feminist critique of the restructuring of the modern university in Australia. It considers the interaction of the processes of globalisation, corporatisation (through the twin strategies of marketisation and managerialism) and the social relations of gender, and their implication for gender equity work in the academy. The paper locates the reform of Australian universities within their Western context, and considers the gendered effects of the new disciplinary technologies of quality assurance and online learning on the position of women academics. It concludes with some comments about the shift in language from equity to diversity which has accompanied corporatisation, and how this has effectively coopted women's intellectual labour to do the work of the entrepreneurial university.

This paper poses the question, what impact have student evaluations (SE’s) of teaching had on the improvement in teaching in Australian tertiary education. The paper proposes to assess the effectiveness of SE’s through an investigations of the ways in which have been used in Australian tertiary education over the last 20 years or so. Three approaches are discussed: a) quality assurance - student evaluations used to ensure the quality of the learning environment in which learning takes place; b) quality improvement - student evaluations used as a diagnostic tool for individual teaching staff; and c) student feedback – student evaluations used to provide prospective and current students with information to help inform their choices and expectations. The discussions reviews some of the research and known practise in Australian universities. It concludes that SE’s have had a profound impact on pedagological understandings of tertiary education by placing the student at centre stage of teaching and learning. However it suggests that we do not know how SE’s have impacted on teaching effectiveness and improvement. The paper concludes by recommending further research to define critical success factors, a better understanding of how to make the student feedback and evaluation tools and mechanisms more approachable and meaningful for students, and an assessment of the ‘survey industry’ as a sustainable enterprise.

As part of a larger Simplification Project for program quality assurance processes conducted at RMIT University, this paper chronicles the refinement of one aspect: program assessment and reporting. This involved the realignment of criteria used in program quality assurance with those developed in higher-level strategic and business planning processes. In addition, the project attempted to address the lack of alignment between annual program processes and subsequent decisions made about the future of programs, particularly in profile planning processes.
A revised Program Annual Report process was developed that aimed to achieve simplicity and alignment while re-engaging program leaders and heads of schools with the quality agenda. A concerted effort was made to develop a process that improved on previously poor vertical communication inherent in program quality assurance. This paper explores the ways in which this was achieved by a) linking people to data through the use of agreed and contextualised performance indicators, and b) linking people to process through more meaningful input into planning and opportunity for dialogue.

Education programs should be based on research about the knowledge and skills required for practice, rather than on intuition or tradition, but there is limited published curriculum research on health promotion education. This paper describes a case study of how workforce competencies have been used to assist evidence-based health promotion education in the areas of curriculum design, selection of assessment tasks and continuous quality assurance processes in an undergraduate program at an Australian university. A curriculum-competency mapping process successfully identified gaps and areas of overlap in an existing program. Previously published health promotion workforce competencies were effectively used in the process of selecting assessment items, providing clear guidelines for curriculum revision and a useful method to objectively assess competency content in an evidence informed framework. These health promotion workforce competencies constituted an additional tool to assess course quality. We recommend other tertiary institutions consider curriculum-competency mapping and curriculum based assessment selection as quality and evidence based curriculum review strategies.

Purpose – The objective is to describe a selection of sustainability components of leadership effectiveness in organizational performance.
Design/methodology/approach – The paper is based on a conceptual discussion. Findings – The paper contributes to descriptive models that address sustainability components of leadership effectiveness in organizational performance. The study highlights some common views that exist in the management literature and in prosperous management practice related to the direct impact of the relationship in organizational performance between leadership and effectiveness. In fact, it also highlights the critical or sceptical views of leadership effectiveness in organizational performance raised in the literature. Research limitations/implications – The paper contends that the actual leadership effectiveness in organizational performance varies over time and across contexts. At times, the achievement in organizational performance is the outcome of prosperous and conscious leadership, while it at other times may be the outcome of poor and deficient leadership. The topic at hand is positioned and limited to the interface that may describe and explain the connection between these two views. Furthermore, it is limited to corporate decision making and business behaviour in relation to leadership effectiveness and organizational performance. Practical implications – The leadership of an organization need not only to be successful today, but they also need to be successful tomorrow to stay in control and to flourish. Quality control and quality assurance are no longer enough for most organizations. They need to build an awareness of the sustainability components into processes of their management and business practices (i.e. internal and external ones) in order to be judged as successful in corporate decision-making and business behaviour in organizational performance in the long term. Originality/value – The principal contributions of the study are a model of timely leadership effectiveness, a model of contextual leadership effectiveness, and a typology of leadership effectiveness in corporate decision-making and business behaviour. These contributions provide theoretical and managerial ideas and insights into the sustainability components of leadership effectiveness in organizational performance.

This paper draws on work by the author as part of a team undertaking an ARC Discovery project entitled: The Impact of Risk Management on Doctoral Research Policy and Pedagogy in Australian Universities. The team is Erica McWilliam, Peter Taylor, Terry Evans and Alan Lawson, with Eluned Lloyd and Karen Tregenza. Some of the ideas in this paper reflect our discussions, reading and other work as part of this project.

Arguably, part of any manager’s work involves the identification and assessment of risks and then working to minimise or manage them. However, never has this been more important than is the case today for the manager of doctoral studies in Australia. Partly this is related to the rising risk consciousness and risk aversion in contemporary societies, but more particularly it is related to the dangers and harms that have been infused by the Australian government into its policies on ‘research training’ (that is, principally doctoral education) and quality assurance. This article explores the consequences of these two trends, one general and one specific, on the management and nature of doctoral research in Australia.

Aims and objectives: To examine the impact and obstacles that individual Institutional Research Ethics Committee (IRECs) had on a large-scale national multi-centre clinical audit called the National Benchmarks and Evidence-based National Clinical guidelines for Heart failure management programmes Study.

Background
: Multi-centre research is commonplace in the health care system. However, IRECs continue to fail to differentiate between research and quality audit projects.

Methods: The National Benchmarks and Evidence-based National Clinical guidelines for Heart failure management programmes study used an investigator-developed questionnaire concerning a clinical audit for heart failure programmes throughout Australia. Ethical guidelines developed by the National governing body of health and medical research in Australia classified the National Benchmarks and Evidence-based National Clinical guidelines for Heart failure management programmes Study as a low risk clinical audit not requiring ethical approval by IREC.

Results
: Fifteen of 27 IRECs stipulated that the research proposal undergo full ethical review. None of the IRECs acknowledged: national quality assurance guidelines and recommendations nor ethics approval from other IRECs. Twelve of the 15 IRECs used different ethics application forms. Variability in the type of amendments was prolific. Lack of uniformity in ethical review processes resulted in a six- to eight-month delay in commencing the national study.

Conclusions
: Development of a national ethics application form with full ethical review by the first IREC and compulsory expedited review by subsequent IRECs would resolve issues raised in this paper. IRECs must change their ethics approval processes to one that enhances facilitation of multi-centre research which is now normative process for health services.

Relevance to clinical practice: The findings of this study highlight inconsistent ethical requirements between different IRECs. Also highlighted are the obstacles and delays that IRECs create when undertaking multi-centre clinical audits. However, in our clinical practice it is vital that clinical audits are undertaken for evaluation purposes. The findings of this study raise awareness of inconsistent ethical processes and highlight the need for expedient ethical review for clinical audits.
