Full textAbstract:
In recent years, influenced by the pervasive power of technology, standards and mandates, Australian hospitals have begun exploring digital forms of keeping this record. The main rationale is the ease of accessing different data sources at the same time by varied staff members. The initial step in this transition was implementation of scanned medical record systems, which converts the paper based records to digitised form, which required process flow redesign and changes to existing modes of work. For maximising the benefits of scanning implementation and to better prepare for the changes, Austin Hospital in the State of Victoria commissioned this research focused on elective admissions area. This structured case study redesigned existing processes that constituted the flow of external patient forms and recommended a set of best practices at the same time highlighting the significance of user participation in maximising the potential benefits anticipated. In the absence of published academic studies focused on Victorian hospitals, this study has become a conduit for other departments in the hospital as well as other hospitals in the incursion.

Full textAbstract:
With a brief description of the physical setting and institutional history of the Australian water sector, this paper reviews the water institutional reforms in Australia focusing especially on the nature and extent of reforms initiated since 1995 and provides a few case studies to highlight the issues and challenges in effecting changes in some key reform components. The reforms initiated in 1995 are notable for their comprehensiveness, fiscal incentives and clear and time-bound targets to be achieved. Although water institutions in Australia have undergone remarkable changes, thanks to the reforms, there are still issues and challenges inherent in reforming maturing water institutions. Regional diversity in legal systems and quality standards as well as conflicts between private interest and public welfare are still serious to constraining market-based water allocation and management. While Australia still needs further reforms, its recent reform experience provides considerable insights into the understanding of both the theory and the practice of water institutional reforms.

Full textAbstract:
Prefabrication has been shown to be an effective way of construction in the modern-day context. Although much progress has been made in developing reinforced concrete (RC), timber and steel prefabricated elements/structures, prefabrication of masonry walling systems has received limited attention in the past. Conventional masonry construction is labour-intensive and time-consuming; therefore, prefabrication can be an effective solution to accelerate the masonry construction to make it more cost-effective. Therefore, in this paper, an attempt has been made to evaluate the effectiveness of prefabricated masonry systems (PMS) in terms of their structural characteristics and sustainability perspectives in an Australian context. Subsequently, the available studies related to PMS and the prospects of developing prefabricated masonry walling systems were appraised and reported. In order to assess the applicability of PMS, a case study was carried out by designing four types of prospective prefabricated masonry walling systems for a typical housing unit in Australia. It was shown that the reinforced (RM), post-tensioned (PT) and thin layered mortared (TLM) masonry systems are better suited for prefabrication. Later, in order to assess the sustainability of the considered masonry walling systems, life cycle energy analyses were carried using the Environmental Performance in Construction (EPIC) database. It was found that there can be nearly 30% and 15% savings, respectively, in terms of energy saving and CO2 emissions in prefabricated construction than the conventional masonry construction. Finally, the prospects of developing PMS and the need for future research studies on these systems are highlighted.

Abstract The identification of extratropical fronts in reanalyses and climate models is an important climate diagnostic that aids dynamical understanding and model verification. This study compares six frontal identification methods that are applied to June and July reanalysis data over the Central Wheatbelt of southwest Western Australia for 1979–2006. Much of the winter rainfall over this region originates from frontal systems. Five of the methods use automated algorithms. These make use of different approaches, based on shifts in 850-hPa winds (WND), gradients of temperature (TGR) and wet-bulb potential temperature (WPT), pattern matching (PMM), and a self-organizing map (SOM). The sixth method was a manual synoptic technique (MAN). On average, about 50% of rain days were associated with fronts in most schemes (although methods PMM and SOM exhibited a lower percentage). On a daily basis, most methods identify the same systems more than 50% of the time, and over the 28-yr period the seasonal time series correlate strongly. The association with rainfall is less clear. The WND time series of seasonal frontal counts correlate significantly with Central Wheatbelt rainfall. All automated methods identify fronts on some days that are classified as cutoff lows in the manual analysis, which will impact rainfall correlations. The front numbers identified on all days by the automated methods decline from 1979 to 2006 (but only the TGR and WPT trends were significant at the 10% level). The results here highlight that automated techniques have value in understanding frontal behavior and can be used to identify the changes in the frequency of frontal systems through time.

Full textAbstract:
Transit agencies increasingly deploy planning strategies to improve service reliability and real-time operational control to mitigate the effects of travel time variability. The design of such strategies can benefit from a better understanding of the underlying causes of travel time variability. Despite a significant body of research on the topic, findings remain influenced by the approach used to analyze the data. Most studies use linear regression to characterize the relationship between travel time reliability and covariates in the context of central tendency. However, in many planning applications, the actual distribution of travel time and how it is affected by various factors is of interest, not just the condition mean. This paper describes a quantile regression approach to analyzing the impacts of the underlying determinants on the distribution of travel times rather than its central tendency, using supply and demand data from automatic vehicle location and farecard systems collected in Brisbane, Australia. Case studies revealed that the quantile regression model provides more indicative information than does the conditional mean regression method. Moreover, most of the coefficients estimated from quantile regression are significantly different from the conditional mean–based regression model in terms of coefficient values, signs, and significance levels. The findings provide information related to the impacts of planning, operational, and environmental factors on speed and its variability. On the basis of this information, transit designers and planners can design targeted strategies to improve travel time reliability effectively and efficiently.

Australian Journal of Experimental Agriculture 43, no. 3 (2003): 205. http://dx.doi.org/10.1071/ea01012.
Full textAbstract:
During the last decade, a range of indicators has been advocated for assessing soil, farm and catchment health. This paper assembles some recent experiences of the authors in developing and using indicators from paddock to national scales. Indicators are merely a subset of the attributes that are used to quantify aspects of catchment or farm health. Their selection and use in the past has led to criticism of indicators, but, given an explicit approach, most of the criticisms can be overcome. Reliable indicators provide positive and negative signals about the current status of natural resources and how these properties have changed over time. They are used both to identify potential risks and to confirm that current farming practices and systems of land use are effective in maintaining the resource base or economic status. They should be precursors for change and future on-ground investments when problems are observed or identified.A structured approach is needed to ensure indicators are selected and used efficiently. This approach involves: deciding local issues and selecting the most appropriate indicators to reflect those issues; interpreting both positive and negative signals from the monitoring process; taking appropriate action to resolve problems; and, using indicators to monitor the outcomes from the action taken.Finally, we have drawn on these and other experiences to compile a list of indicators that may be used to address sustainability issues associated with farm productivity, soil health and catchment health identified in recent strategic plans developed for the northern grains region of Australia, the focus of this special journal issue.

Full textAbstract:
Changes in the farm operating and policy environments and a need to remain profitable under a cost-price squeeze have contributed to dairy systems in Australia and New Zealand becoming more intensive and complex in recent decades. Farm systems in both countries are now diverse, varying from being based predominantly on pasture with little purchased supplements, to those dependent on high levels of feed supplements and even having zero grazing. Dairy farm performance (defined in this paper as production or technical performance), return (return on assets or profit) and risk (variation in economic performance over time), and intensity of dairy systems was examined using farm survey data, case studies and existing published studies. The level of single technical performance measures, such as milk production, feed conversion efficiency and pasture consumption, prevailing in a business are not guides to the operating profit and return on assets of a business. In addition, when survey data of farm performance was grouped by return on assets, few farms were in the top 25% in successive years. Farms that performed consistently well were characterised by good, but not extreme, technical performance in a range of key areas, which translated to favourable business return (return on asset and profit). The knowledge and skills of farm managers are critical, and means that many different dairy systems can perform well physically and financially and successfully meet farmer goals. The relation between risk and the intensity of dairy systems was also investigated. Options that intensified systems generally resulted in higher net wealth for the farm owner, but almost always at increased risk. The best system for any farmer to operate is one which best meets their multifaceted preferences and goals, regardless of system type.

"Impact of Technical, Human, and Organizational Risks on Reliability of Fire Safety Systems in High-Rise Residential Buildings—Applications of an Integrated Probabilistic Risk Assessment Model." Applied Sciences 10, no. 24 (December 14, 2020): 8918. http://dx.doi.org/10.3390/app10248918.
Full textAbstract:
The current paper presents an application of an alternative probabilistic risk assessment methodology that incorporates technical, human, and organizational risks (T-H-O-Risk) using Bayesian network (BN) and system dynamics (SD) modelling. Seven case studies demonstrate the application of this holistic approach to the designs of high-rise residential buildings. An incremental risk approach allows for quantification of the impact of human and organizational errors (HOEs) on different fire safety systems. The active systems considered are sprinklers, building occupant warning systems, smoke detectors, and smoke control systems. The paper presents detailed results from T-H-O-Risk modelling for HOEs and risk variations over time utilizing the SD modelling to compare risk acceptance in the seven case studies located in Australia, New Zealand, Hong Kong, Singapore, and UK. Results indicate that HOEs impact risks in active systems up to ~33%. Large variations are observed in the reliability of active systems due to HOEs over time. SD results indicate that a small behavioral change in ’risk perception’ of a building management team can lead to a very large risk to life variations over time through the self-reinforcing feedback loops. The quantification of difference in expected risk to life due to technical, human, and organizational risks for seven buildings for each of 16 trial designs is a novel aspect of this study. The research is an important contribution to the development of the next generation building codes and risk assessment methods.

Full textAbstract:
The large number of wells associated with typical coal seam gas (CSG) developments in Australia has changed the paradigm for field management and optimisation. Real time data access, automation and optimisation—which have been previously considered luxuries in conventional resources—are key to the development and operation of fields, which can easily reach more than 1,000 wells. The particular issue in Australia of the shortage of skilled labour and operators has increased pressure to automate field operations. This extended abstract outlines established best practices for gathering the numerous data types associated with wells and surface equipment, and converting that data into information that can inform the decision processes of engineers and managers alike. There will be analysis made of the existing standard, tools, software and data management systems from the conventional oil and gas industry, as well as how some of these can be ported to the CSG fields. The need to define industry standards that are similar to those developed over many years in the conventional oil and gas industry will be discussed. Case studies from Australia and wider international CSG operations will highlight the innovative solutions that can be realised through an integrated project from downhole to office, and how commercial off the shelf solutions have advantages over customised one-off systems. Furthermore, case studies will be presented from both CSG and conventional fields on how these enabling technologies translate into increased production, efficiencies and lift optimisation and move towards the goal of allowing engineers to make informed decisions as quickly as possible. Unique aspects of CSG operations, which require similarly unique and innovative solutions, will be highlighted in contrast to conventional oil and gas.

Full textAbstract:
Protected areas remain a cornerstone for global conservation. However, their effectiveness at halting biodiversity decline is not fully understood. Studies of protected area benefits have largely focused on measuring their impact on halting deforestation and have neglected to measure the impacts of protected areas on other threats. Evaluations that measure the impact of protected area management require more complex evaluation designs and datasets. This is the case across realms (terrestrial, freshwater, marine), but measuring the impact of protected area management in freshwater systems may be even more difficult owing to the high level of connectivity and potential for threat propagation within systems (e.g. downstream flow of pollution). We review the potential barriers to conducting impact evaluation for protected area management in freshwater systems. We contrast the barriers identified for freshwater systems to terrestrial systems and discuss potential measurable outcomes and confounders associated with protected area management across the two realms. We identify key research gaps in conducting impact evaluation in freshwater systems that relate to three of their major characteristics: variability, connectivity and time lags in outcomes. Lastly, we use Kakadu National Park world heritage area, the largest national park in Australia, as a case study to illustrate the challenges of measuring impacts of protected area management programmes for environmental outcomes in freshwater systems.

IntroductionRobot-Assisted Surgery (RAS) has been available in Australia since 2003. There are 50 da Vinci RAS systems in Australia (18 in NSW and 12 in Victoria) with most in the private hospital sector. In Australia the capital cost of a da Vinci RAS system is up to AUD 4 million (USD 2.8 million), which excludes annual maintenance fees of AUD 250,000 (USD 175,000) and consumable costs of AUD 3,500 (USD 2,450) for each procedure.MethodsThe NSW Ministry of Health and Victorian Department of Health and Human Services commissioned a health technology assessment (HTA) to explore the benefits, risks and economic implications of surgical robotics, which involved a review of the peer reviewed literature, a cost benefit analysis of public sector patients who received RAS and broad stakeholder consultation to document current perspectives on RAS applications.ResultsRAS is as safe and effective as other surgical modalities when performed by sufficiently skilled surgeons, although evidence generally comes from small studies with limited follow-up time and few studies report long term mortality, morbidity or patient-reported outcomes. Comparative benefits of RAS are uncertain as most studies conclude little or no difference in procedure related or functional outcomes. While RAS reduces length of stay, which offers patient and health system benefits, this is insufficient to fully offset high capital and consumable costs currently charged to Australian providers. Government and clinical stakeholders identified that establishing an RAS service requires consideration of important factors, including: i) Governance is critical; ii) Higher case volumes may improve financial viability; and iii) a need for state-wide/national standards for surgeon training and credentialing.ConclusionsRAS is as safe and effective as other modalities when performed by skilled surgeons. However, uncertainty remains around long-term outcomes and clinical and cost effectiveness. An accredited training program, monitoring and evaluation will be critical to ensure outcomes data inform ongoing evidence assessment and government policy and investment.

Abstract This final article in our 12-part series articulating a suite of quality improvement studies completes our report on the Deepening our Understanding of Quality in Australia (DUQuA) program of work. Here, we bring the Supplement’s key findings and contributions together, tying up loose ends. Traversing the DUQuA articles, we first argued the case for the research, conducted so that an in-depth analysis of one country’s health system, completed 5 years after the landmark Deepening our Understanding of Quality Improvement in Europe (DUQuE), was available. We now provide a digest of the learning from each article. Essentially, we have contributed an understanding of quality and safety activities in 32 of the largest acute settings in Australia, developed a series of scales and tools for use within Australia, modifiable for other purposes elsewhere, and provided a platform for future studies of this kind. Our main message is, despite the value of publishing an intense study of quality activities in 32 hospitals in one country, there is no gold standard, one-size-fits-all methodology or guarantee of success in quality improvement activities, whether the initiatives are conducted at departmental, organization-wide or whole-of-systems levels. Notwithstanding this, armed with the tools, scales and lessons from DUQuA, we hope we have provided many more options and opportunities for others going about strengthening their quality improvement activities, but we do not claim to have solved all problems or provided a definitive approach. In our view, quality improvement initiatives are perennially challenging, and progress hard-won. Effective measurement, evaluating progress over time, selecting a useful suite of quality methods and having the persistence to climb the improvement gradient over time, using all the expertise and tools available, is at the core of the work of quality improvement and will continue to be so.

APPEA Journal 60, no. 1 (2020): 335. http://dx.doi.org/10.1071/aj19187.
Full textAbstract:
Large sedimentary basins with multiple aquifer systems like the Great Artesian Basin and the Beetaloo Sub-Basin are associated with large time and spatial scales for regional groundwater flow and mixing effects from inter-aquifer exchange. This makes them difficult to study using traditional hydrogeological investigation techniques. In continental onshore Australia, such sedimentary aquifer systems can also be important freshwater resources. These resources have become increasingly stressed because of growing demand and use of groundwater by multiple industries (e.g. stock, irrigation, mining, oil and gas). The social licence to operate for extractive oil and gas industries increasingly requires robust and reliable scientific evidence on the degree to which the target formations are vertically and laterally hydraulically separated from the aquifers supplying fresh water for stock and agricultural use. The complexity of such groundwater interactions can only be interpreted by applying multiple lines of evidence including environmental isotopes, hydrochemistry, hydrogeological and geophysical observations. We present an overview of multi-tracer studies from coal seam gas areas (Queensland and New South Wales) or areas targeted for shale gas development (Northern Territory). The focus was to investigate recharge to surficial karst and deep confined aquifer systems before industrial extraction on time scales of decades up to one million years and aquifer inter-connectivity at the formation scale. A systematic and consistent methodology is applied for the different case study areas aimed at building robust conceptual hydrogeological models that inform groundwater management and groundwater modelling. The tracer studies provided (i) in all areas increased confidence around recharge estimates, (ii) evidence for a dual-porosity flow system in the Hutton Sandstone (Queensland) and (iii) new insights into the connectivity, or lack thereof, of flow systems.

Full textAbstract:
A methodology for validating fire spread simulation systems using historical fire data is presented. The key features of this methodology are (a) quantitative comparison between simulator-generated fire perimeters and fire perimeters from an independently produced fire reconstruction at multiple time points during the fire, and (b) extensive sensitivity analyses on simulation variables including simulation spatial resolution, weather, vegetation coverage and fire behaviour model selection to determine the effect of each simulation input on the simulation output. The methodology is demonstrated in a case study in which the ability of the Australis high-performance wildfire simulator to replicate a large wildfire in Western Australia was examined. Simulation accuracy was found to be lower in extreme fire danger conditions and exhibited under-prediction of the head fire rate of spread. This was caused by inaccuracies in at least one of wind speed data, vegetation data or the fire behaviour model applied; however, the source of the inaccuracy could not be further diagnosed with the available data. The gathering of accurate data during and after active wildfires would facilitate more rigorous simulator and fire behaviour model validation studies as well as more accurate prediction of ‘live’ wildfires.

Full textAbstract:
AbstractWhilst much has been written about the opportunities and perils of Green participation in national coalition governments, analysis of Greens supporting minority governments is less common and has not focused on comparative-historical trends as this article does. We look beyond single case studies of Green-supported minority governments in order to establish historical party trajectories and policy impact over time in three countries with different political systems. The extent of the comparative work here has never previously been undertaken and establishes that repeat instances of such support can provide the basis for more stable and effective future interparty governing relationships. However, we argue that, whilst trust can build between parties to minority government arrangements over decades, it is not assured, and, whilst Green parties may achieve ministerial control after repeat instances of supporting minority governments, the benefits of doing so are not guaranteed.

Full textAbstract:
Human behaviour is a major driver and determinant of household energy consumption, with routines and practices shaping daily energy profiles. These routines and practices are made up of individual lifestyles and other contextual factors that vary from home to home. Social and psychological theories aim to explain and describe how people consume resources in the home, which has resulted in the development of the home system of practice. This evaluates how occupants live and follow multiple routines which result in varying energy consumption practices. This paper develops a methodology to identify and support the concept of the home system of practice using a data analytical approach and link it to residential energy and distribution network management. This paper utilises k-means cluster analysis to identify these different home systems of practices and routines in energy use by using real-time energy consumption data from July 2019 to March 2021 from a living laboratory in Australia. The results of the analysis show the different daily energy profiles for each of the 39 households, with some homes observing large fluctuations and changes in the way they consume energy during the day. Specific homes were discussed as case studies in this paper focusing on linking the occupants’ contextual factors to their energy profiles. This variation is discussed in terms of the routines of the occupants and associated lifestyles that explain why some energy peaks occurred at different parts of the day and differed during the COVID-19 lockdown period in Australia. The paper conducts a comparison between these case studies to show how people’s lifestyles impact household energy consumption (and variation). These case studies investigated the heating and cooling practices of the occupants to demonstrate how they impact overall consumption. This variation is discussed in relation to energy management and prediction of when homes will consume energy to assist in net-zero energy developments and grid stabilisation operations.

Full textAbstract:
This paper develops new practical rule-based energy management systems (EMSs) for typical grid-connected houses with solar photovoltaic (PV) and battery by considering different rates for purchasing and selling electricity. The EMSs are developed to supply the household’s loads and reduce operating costs of the system based on different options of flat and time-of-use (ToU) rates for buying and selling electricity prices. Four different options are evaluated and compared in this study: (1) Flat-Flat, (2) ToU-Flat, (3) Flat-ToU, and (4) ToU-ToU. The operation cost is calculated based on the electricity exchange with the main grid, the equivalent cost of PV generation, as well as the degradation cost of battery storage. The operation of the grid-connected house with rooftop solar PV and battery is evaluated for a sunny week in summer and a cloudy week in winter to investigate the proper performance for high and low generations of PV. While the developed rule-based EMS are generic and can be applied for any case studies, a grid-connected house in Australia is examined. For this purpose, real data of solar radiation, air temperature, electricity consumption, and electricity rates are used. It is found that the ToU-Flat option has the lowest operating cost for the customers.

Numerous studies in urban resilience have been published in the past decade. However, only a few publications have tracked the evolution trends of urban resilience research, the findings of which can serve as a useful guide for scholars to foresee worth-effort research areas and make the best use of precious time and resources. In order to fill the research gap, this study performed a scientometric analysis on the evolution trends of urban resilience research using a versatile software package-CiteSpace. The scientomentric analysis focuses on distribution of lead authors and their institutions, high frequency categories and keywords, high influential journals, author contribution, and evolutionary trends based on co-author analysis, co-word analysis, co-citation analysis and cluster analysis of documents. This study discoveries that first, the U.S., England, Australia, Canada, China and Sweden are the countries that make the most significant contributions in the advancement of urban resilience research; second, the existing urban resilience research focuses primarily on environmental studies, geography and planning development; third, hot topics of the urban resilience research keep shifting from 1993 to 2016; fourth, the knowledge body of urban resilience research consists of five clusters: resilience exploratory analysis, disaster resilience, urban resilience, urban resilience practice, and social-ecological systems; last, the emerging trends in urban resilience research include defining urban resilience, adaptation model, case studies, analytical methods and urban social-ecological systems, resulting in cutting-edge research areas in urban resilience.

ObjectivesComprehensive reporting of surgical disease burden and outcomes are vital components of resilient health systems but remain under-reported. The primary objective was to identify the Victorian surgical burden of disease necessitating treatment in a hospital or day centre, including a thorough epidemiology of surgical procedures and their respective perioperative mortality rates (POMR).DesignRetrospective population-level observational study.SettingThe study was conducted in Victoria, Australia. Access to data from the Victorian Admitted Episodes Dataset was obtained using the Dr Foster Quality Investigator tool. The study included public and private facilities, including day-case facilities.ParticipantsFrom January 2014 to December 2016, all admissions with an International Statistical Classification of Diseases-10 code matched to the Global Health Estimates (GHE) disease categories were included.Primary and secondary outcome measuresAdmissions were assigned a primary disease category according to the 23 GHE disease categories. Surgical procedures during hospitalisations were identified using the Australian Refined Diagnosis Related Groups (AR-DRG). POMR were calculated for GHE disease categories and AR-DRG procedures.ResultsA total of 4 865 226 admitted episodes were identified over the 3-year period. 1 715 862 (35.3%) of these required a surgical procedure. The mortality rate for those undergoing a procedure was 0.42%, and 1.47% for those without. The top five procedures performed per GHE category were lens procedures (162 835 cases, POMR 0.001%), caesarean delivery (76 032 cases, POMR 0.01%), abortion with operating room procedure (65 451 cases, POMR 0%), hernia procedures (52 499 cases, POMR 0.05%) and other knee procedures (47 181 cases, POMR 0.004%).ConclusionsConditions requiring surgery were responsible for 35.3% of the hospital admitted disease burden in Victoria, a rate higher than previously published from Sweden, New Zealand and the USA. POMR is comparable to other studies reporting individual procedures and conditions, but has been reported comprehensively across all GHE disease categories for the first time.

ABSTRACT Microbial contamination of fresh produce (fresh fruits and vegetables) poses serious public health concerns worldwide. This study was conducted as a comprehensive analysis of biological hazards in the global fresh produce chain. Data about produce-related outbreaks and illness were collected from the annual reports and databases of foodborne outbreak surveillance systems in different regions and countries from 2010 to 2015. The global patterns of and regional differences in documented outbreaks and cases were analyzed, and produce commodities and pathogens of greatest concern were identified. Data on sporadic illnesses were also collected through a comprehensive literature review of case-control studies. We found 988 produce-related outbreaks (with known agents) and 45,723 cases in all regions and countries. The numbers of produce-related outbreaks per million person-years were approximately 0.76, 0.26, 0.25, 0.13, 0.12, and 0.05 in New Zealand, Australia, the United States, the European Union, Canada, and Japan, respectively. The top three food categories and pathogens contributing to produce-related outbreaks were vegetables and nonfruits (i.e., food other than fruits; 27.0%), unspecified vegetables (12.2%), and vegetable row crops (11.7%) and norovirus (42.4%), Salmonella enterica (19.9%), and Staphylococcus aureus (7.9%), respectively. Produce consumption was identified as a protective factor, a risk factor, and either a protective or risk factor for sporadic illnesses in 11, 5, and 5 studies, respectively, among 21 case-control studies. Risks associated with produce consumption in the United States and the European Union have been linked to various factors such as irrigation water, cross-contamination, storage time and temperature abuse, infected food handlers, and unprocessed contaminated ingredients. The results of the current study indicate the complexity of produce products consumed across the globe and the difficulty in tracing illnesses back to specific food ingredients.

Full textAbstract:
Stroke represents a major health problem in our society. One of the effects of stroke is foot drop. Foot drop (FD) is a weakness that occurs in specific muscles in the ankle and foot such as the anterior tibialis, gastrocnemius, plantaris and soleus muscles. Foot flexion and extension are normally generated by lower motor neurons (LMN). The affected muscles impact the ankle and foot in both downward and upward motions. One possible solution for FD is to investigate the movement based on the bio signal (myoelectric signal) of the muscles. Bio signal control systems like electromyography (EMG) are used for rehabilitation devices that include foot drop. One of these systems is function electrical stimulation (FES). This paper proposes new methods and algorithms to develop the performance of myoelectric pattern recognition (M-PR), to improve automated rehabilitation devices, to test these methodologies in offline and real-time experimental datasets. Label classifying is a predictive data mining application with multiple applications in the world, including automatic labeling of resources such as videos, music, images and texts. We combine the label classification method with the self-advised support vector machine (SA-SVM) to create an adapted and altered label classification method, named the label self-advised support vector machine (LSA-SVM). For the experimental data, we collected data from foot drop patients using the sEMG device, in the Metro Rehabilitation Hospital in Sydney, Australia using Ethical Approval (UTS HREC NO. ETH15-0152). The experimental results for the EMG dataset and benchmark datasets exhibit its benefits. Furthermore, the experimental results on UCI datasets indicate that LSA-SVM achieves the best performance when working together with SA-SVM and SVM. This paper describes the state-of-the-art procedures for M-PR and studies all the conceivable structures.

Full textAbstract:
Dams affect rivers and other freshwater ecosystems around the world. The structural performance and service delivery of many dams has seldom been assessed; many are unsafe and no longer deliver designed benefits. Changes in hydrology from climate change will require assessment of safety and operations of infrastructure. This creates an opportunity during relicensing for modification or removal of dams to render them safe, maximise their services and minimise social and environmental impacts. We examined case studies of reassessment of dams from Australia (New South Wales), China, France and the United States that illustrated the following: the management challenge of aging and unsafe dams; unrealised opportunities to improve environmental, social and economic benefits; and the benefits of inventory and relicensing systems. Key elements of an ideal regulatory system to optimise water infrastructure performance are identified, comprising periodic (time-limited) relicensing of all infrastructure overseen by an independent regulatory agency that would take decisions in the public interest through a transparent process, involving public participation. Each dam would have an identified owner who must apply best-available technologies to maximise safety, socioeconomic and environmental performance. Dam renovation could minimise current non-climate impacts, improve migration of aquatic wildlife and even attenuate some climate impacts on freshwater biota.

Purpose This paper aims to outline campus management process dynamics that are affected by glocalization, changing funding structures and digitalization, and answer: How do glocalization, changing funding structures and digitalization challenge university campus management? and What implications do the challenges have on campus management processes? Design/methodology/approach Literature overview discusses how glocalization, changing funding structures and digitalization affect campus management. Empirical part explores how these forces affect management processes through 36 interviews on multiple embedded cases in the main campuses of Aalto University in Finland and the University of Melbourne in Australia. Findings Major challenges include future foresight, institutional sharing, economical paucity and functional flexibility. Heterogeneous user behaviors challenge absolute spatial measures as bases for designing learning and working environments. Finding a balance between long-haul portfolio maintenance for the university and future users and short-haul flexible pilots for the current user communities is crucial. Research limitations/implications The results derive from interviews of 36 campus management professionals from two campus management organizations limiting the validity and the reliability of the study. Further studies should be conducted by replicating the study in another context, by interviewing end users and clients and by investigating case investments and impacts over time. Practical implications Campus managers can answer the challenges through practical applications such as big data collection and sharing in physical environments, integrated service provision to thematic communities, cross-pollination of user communities and open access to information and infrastructure services. Originality/value This paper provides insights and tools to strategic alignment by comparing campus management of two fundamentally different systems in the context of higher education and on-going digitalization.

Full textAbstract:
Objective Advancing quality in health services requires structures and processes that are informed by consumer input. Although this agenda is well recognised, few researchers have focussed on the establishment and maintenance of customer input throughout the structures and processes used to produce high-quality, safe care. We present an analysis of literature outlining the barriers and enablers involved in community representation in hospital governance. The review aimed to explore how community representation in hospital governance is achieved. Methods Studies spanning 1997–2012 were analysed using Donabedian’s model of quality systems as a guide for categories of interest: structure, in relation to administration of quality; process, which is particularly concerned with cooperation and culture; and outcome, considered, in this case, to be the achievement of effective community representation on quality of care. Results There are limited published studies on community representation in hospital governance in Australia. What can be gleaned from the literature is: 1) quality subcommittees set up to assist Hospital Boards are a key structure for involving community representation in decision making around quality of care, and 2) there are a number of challenges to effectively developing the process of community representation in hospital governance: ambiguity and the potential for escalated indecision; inadequate value and consideration given to it by decision makers resulting in a lack of time and resources needed to support the community engagement strategy (time, facilitation, budgets); poor support and attitude amongst staff; and consumer issues, such as feeling isolated and intimidated by expert opinion. Conclusions The analysis indicates that: quality subcommittees set up to assist boards are a key structure for involving community representation in decision making around quality of care. There are clearly a number of challenges to effectively developing the process of community representation in hospital governance, associated with ambiguity, organisational and consumer issues. For an inclusive agenda to real life, work must be done on understanding the representatives’ role and the decision making process, adequately supporting the representational process, and developing organisational cooperation and culture regarding community representation. What is known about the topic? Partnering community is recognised as a fundamental element of hospital quality improvement strategies and the implementation of the Australian agenda for advancing the quality of health service standards. It is also known that developing collaborative environments and partnerships can be a challenging process, and that it is good practice to consider the factors that will influence their success and develop an approach built on the identification of potential challenges and the incorporation of facilitators. What does this paper add? This paper draws out key obstacles that can challenge the process of involving community representation into hospital governance structures. What are the implications for practitioners? There is little published on the challenges to community engagement in the hospital governance setting. By doing this, this paper encourages the recognition that although partnering with the community is an essential aspect of achieving quality of care, it requires significant effort and support to be an effective aspect. The paper highlights challenges and facilitators that practitioners should consider if planning for successful community representation on hospital committees.

"Prospectivity insights from automated pre-interpretation processing of open-file 3D seismic data: characterising the Late Triassic Mungaroo Formation of the Carnarvon Basin, North West Shelf of Australia." APPEA Journal 55, no. 1 (2015): 15. http://dx.doi.org/10.1071/aj14002.
Full textAbstract:
Waveform data from pre-interpretation processing is used in nine Late Triassic interpretation case studies from an area extending more than 30,000 km2 across the Exmouth Plateau, Kangaroo Trough and Rankin Trend on the North West Shelf of Australia. Events selected from a database of automatically generated surfaces extracted from six large open-file 3D marine surveys (~16,000 km2) are used to analyse reservoirs, seals, and pore fluid within the Brigadier and Mungaroo formations in this peer-reviewed paper. Today, geoscience teams are challenged with vast data sets such as the archived versions of more than 125 Carnarvon Basin 3D seismic surveys. Pre-interpretation processing delivers a database of numerous seismic events that cannot be effectively managed using traditional interpretation workstations. With, however, a 3D viewer to query, edit and merge the results, geoscience teams are able to review many large surveys and the surfaces in their interpretation workflows. At the 2013 WABS Conference in Perth, WA, two papers offered models for the Late Triassic gas reservoirs. These models represent many years of synthesis and integration of data by teams of geoscientists from two of the major operators on the North West Shelf. Validation and corroboration of the proposed models was gained by using selected pre-interpretation surfaces. Stacking patterns, waveform fitness, amplitude and two-way time surfaces from these spatial databases revealed geological insights about the formations, such as their complexity of structure, extent of reservoirs, and continuity of seals, along with a better understanding about the trapping and charge systems of the fields.

Full textAbstract:
This paper reviews some key memoir studies, which were carried out in South Australia, and considers their process of data collection and analysis. A second aim is to explore the current status and usefulness of Znaniecki’s memoir approach in contemporary educational research. Smolicz followed Znaniecki in emphasizing the need to accept social and cultural values and actions as facts, just as human agents themselves accept them. Every individual was seen as a member of various group social systems and interpreted as a center of experience and actions based on the cultures of those groups. Smolicz also adopted Znaniecki’s memoir method of collecting and analyzing personal data in order to understand the actions and attitudes of young people of immigrant families and their educational experiences in Australian schools. These conscious human agents played an important role in maintaining and changing their group’s cultural systems. This paper highlights examples of various forms of memoirs collected from four different studies focused specifically on the issue of cultural identity. The comments of the participants, who came from various minority ethnic groups living in Australia, illustrate the nature of the comments made, as well as the researchers’ analysis and findings. The research studies of Smolicz and his associates demonstrate that memoir method has an important place in understanding the culture of different groups, which can be applied in many contexts – global, ethnic, national, and local.

Full textAbstract:
ISCPES stands for International Society for Comparative Physical Education and Sports and it is going to celebrate its 40th anniversary in 2018. Since the beginning (Israel 1978) the main goals of the Society were established under a worldwide mind set considering five continents and no discrimination of any kind. The founders wanted to compare Physical Education and Sports across the world, searching for the best practices deserving consideration and applied on the purpose of improving citizen quality of life. The mission still stands for “Compare to learn and improve”.As all the organizations lasting for 39 years, ISCPES experienced several vicissitudes, usually correlated with world economic cycles, social and sports changes, which are in ISS journal articles - International Sport Studies.ISS journal is Scopus indexed, aiming to improve its quality (under evaluation) to reach more qualified students, experts, professionals and researchers; doing so it will raise its indexation, which we know it is nowadays a more difficult task. First, because there are more journals trying to compete on this academic fierce competitive market; secondly, because the basic requirements are getting more and more hard to gather in the publishing environment around Physical Education and Sports issues. However, we can promise this will be one of our main strategic goals.Another goal I would like to address on this Editorial is the language issue. We have this second strategic goal, which is to reach most of languages spoken in different continents; besides the English language, we will reach Chinese, Spanish and Portuguese speaking countries. For that reason, we already defined that all the abstracts in English will be translated into Chinese, Spanish and Portuguese words so people can find them on any search browser. That will expand the demand for our journal and articles, increasing the number of potential readers. Of course this opportunity, given by Motricidade, can be considered as a good example to multiply our scope.In June 2017 we organized a joint Conference in Borovets, Bulgaria, with our colleagues from the BCES – Bulgarian Society for Comparative Educational Studies. During those days, there was an election to appoint a new (Portuguese) president. This constitutes an important step for the Portuguese speaker countries, which, for a 4th year term, will have the opportunity to expand the influence of ISCPES Society diffusing the research results we have been achieving into a vast extended new public and inviting new research experts to innovative debates. This new president will be working with a wide geographical diverse team: the Vice President coming from a South American country (Venezuela), and the other several Executive Board members are coming from Brazil, China, Africa and North America. This constitutes a very favorable situation once, adding to this, we kept the previous editorial team from Australia and Europe. We are definitely committed to improve our influence through new incentives to organize several regional (continental) workshops, seminars and Conferences in the next future.The international research is crossing troubled times with exponential number of new indexed journals trying to get new influence and visibility. In order to do that, readers face new challenges because several studies present contradictory conclusions and outcome comparisons still lacking robust methodologies. Uncovering these issues is the focus of our Society.In the past, ISCPES started its activity collecting answers to the same questions asked to several experts in different countries and continents across the world. The starting studies developed some important insights on several issues concerning the way Physical Education professionals approached their challenges. In the very starting documents ISCPES activity focused in identifying certain games and indigenous activities that were not understood by people in other parts of the world, improving this international understanding and communication. This first attempt considered six groups of countries roughly comprehending 26 countries from all the continents.ISCPES has on its archives several seminal works, PhD proposals and program proposals, which constitutes the main theoretical framework considered in some textbooks printed at the end of the sixties in the XXth century.The methods used mostly sources’ country comparisons, historic development of comparative education systems, list of factors affecting those systems and a systematic analysis of case studies; additionally, international organizations for sports and physical education were also required to identify basic problems and unique features considered for the implementation of each own system. At the time, Lynn C. Vendien & John E. Nixon book “The World Today in Health, Physical Education and Recreation”, Englewood Cliffs, New Jersey: Prentice-Hall, Inc. 1968, together with two monographies from William Johnson “Physical Education around the World”, 1966, 1968, Indianapolis, Phi Epsilon Kappa editions, were the main textbook references.The main landscapes of interest were to study sports compared or the sport role in Nationalisms, Political subsidization, Religion, Race and volunteering versus professionalism. The goal was to state the true place of sports in societies.In March 1970, Ben W. Miller from the University of California compiled an interesting Exhibit n.1 about the main conclusions of a breakfast meeting occurred during the American Association for Health, Physical Education and Recreation. There, they identified thirty-one individuals, which had separate courses in “Comparative and/or International Physical Education, Recreation and Sports”; one month later, they collected eighteen responses with the bibliographic references they used. On this same Exhibit n.1 there is detailed information on the title, catalogue description, date of initial course (1948, the first), credit units, eligibility, number of year offer, type of graduation (from major to doctorate and professional). Concluding, the end of the sixties can be the mark of a well-established body of literature in comparative education and sports studies published in several scientific journals.What about the XXIst century? Is it still important to compare sports and education throughout the world? Only with qualitative methods? Mixed methods?We think so. That is why, after a certain decline and fuzzy goal definition in research motivations within ISCPES we decided to innovate and reorganize people from physical education and sports around this important theme of comparative studies. Important because we observe an increasing concern on the contradictions across different results in publications under the same subject. How can we infer? What about good research questions which get no statistically significant results? New times are coming, and we want to be on that frontline of this move as said by Elsevier “With RMR (results masked review) articles, you don’t need to worry about what editors or reviewers might think about your results. As long as you have asked an important question and performed a rigorous study, your paper will be treated the same as any other. You do not need to have null results to submit an RMR article; there are many reasons why it can be helpful to have the results blinded at initial review”.https://www.elsevier.com/connect/reviewers-update/results-masked-review-peer-review-without-publication-bias.This is a very different and challenging time. Our future strategy will comprehend more cooperation between researchers, institutions and scientific societies as an instrument to leverage our understanding of physical activity and sports through different continents and countries and be useful for policy designs.Next 2018, on the occasion of the UE initiative Sofia – European Capital of Sport 2018 we - Bulgarian Comparative Education Society (BCES) & the International Society for Comparative Physical Education and Sport (ISCPES) - will jointly organize an International Conference on Sport Governance around the World.Sports and Physical Education are facing complex problems worldwide, which need to be solved. For health reasons, a vast number of organizations are popularizing the belief that physical education and sports are ‘a must’ in order to promote human activity and movement. However, several studies show that modern lifestyles are the main cause for people's inactivity and sedentary lifestyles.Extensive funded programs used to promote healthy lifestyles; sports media advertising several athletes, turning them into global heroes, influencers in a new emerging industry around sports organizations. Therefore, there is a rise in the number of unethical cases and corruption that influence the image of physical education and sports roles.We, the people emotional and physically involved with sports and physical activity must be aware of this, studying, discussing and comparing global facts and events around the world.This Conference aims to offer an incentive to colleagues from all continents to participate and present their latest results on four specific topics: 1. Sport Governance Systems; 2. Ethics and Corruption in Physical Education and Sports Policies; 3. Physical Education and Sport Development; 4. Training Physical Educators and Coaches.

Purpose Through a case study of J. Walter Thompson and Kraft’s efforts to market Vegemite in the USA in the late 1960s, this paper aims to explore transnational systems of cultural production and consumption, the US’s changing perception of Australia and the influence of culture on whether advertising fails or succeeds. Design/methodology/approach This paper draws from archival primary sources, including advertisements and newspapers, as well as secondary literatures from the fields of advertising history, food studies and transnational studies of popular culture. Findings Although J. Walter Thompson’s advertising contributed to Vegemite’s icon status in Australia, it failed to capture the American market in the late 1960s. In the 1980s, however, Vegemite did capture American interest when it was central to a wave of Australian popular culture that included films, sport and music, particularly Men at Work’s hit song, “Down Under”, whose lyrics mentioned Vegemite. As such, Vegemite’s moment of success stateside occurred without a national advertising campaign. Even when popular, however, Americans failed to like Vegemite’s taste, confirming it as a uniquely culturally specific product. Originality/value This paper analyzes a little-studied advertising campaign. The case study’s interdisciplinary findings will be of interest to scholars of advertising history, twentieth century USA and Australian history and food studies.

Full textAbstract:
SUMMARY We present an inversion algorithm tailored for point gravity data. As the data are from multiple surveys, it is inconsistent with regards to spacing and accuracy. An algorithm design objective is the exact placement of gravity observations to ensure no interpolation of the data is needed prior to any inversion. This is accommodated by discretization using an unstructured tetrahedral finite-element mesh for both gravity and density with mesh nodes located at all observation points and a first-order system least-squares (FOSLS) formulation for the gravity modelling equations. Regularization follows the Bayesian framework where we use a differential operator approximation of an exponential covariance kernel, avoiding the usual requirement of inverting large dense covariance matrices. Rather than using higher order basis functions with continuous derivatives across element faces, regularization is also implemented with a FOSLS formulation using vector-valued property function (density and its gradient). Minimization of the cost function, comprised of data misfit and regularization, is achieved via a Lagrange multiplier method with the minimum of the gravity FOSLS functional as a constraint. The Lagrange variations are combined into a single equation for the property function and solved using an integral form of the pre-conditioned conjugate gradient method (I-PCG). The diagonal entries of the regularization operator are used as the pre-conditioner to minimize computational costs and memory requirements. Discretization of the differential operators with the finite-element method (FEM) results in matrix systems that are solved with smoothed aggregation algebraic multigrid pre-conditioned conjugate gradient (AMG-PCG). After their initial setup, the AMG-PCG operators and coarse grid solvers are reused in each iteration step, further reducing computation time. The algorithm is tested on data from 23 surveys with a total of 6519 observation points in the Mt Isa–Cloncurry region in north–west Queensland, Australia. The mesh had about 2.5 million vertices and 16.5 million cells. A synthetic case was also tested using the same mesh and error measures for localized concentrations of high and low densities. The inversion results for different parameters are compared to each other as well as to lower order smoothing. Final inversion results are shown with and without depth weighting and compared to previous geological studies for the Mt Isa–Cloncurry region.

Full textAbstract:
Abstract Objective The Deepening our Understanding of Quality in Australia (DUQuA) project is a multisite, multi-level, cross-sectional study of 32 of the largest hospitals in Australia. This overview examines relationships between (i) organization-level quality management systems and department-level quality management strategies and (ii) patient-level measures (clinical treatment processes, patient-reported perceptions of care and clinical outcomes) within Australian hospitals. Design We examined hospital quality improvement structures, processes and outcomes, collecting data at organization, department and patient levels for acute myocardial infarction (AMI), hip fracture and stroke. Data sources included surveys of quality managers, clinicians and patients, hospital visits, medical record reviews and national databases. Outcomes data and patient admissions data were analysed. Relationships between measures were evaluated using multi-level models. We based the methods on the Deepening our Understanding of Quality Improvement in Europe (DUQuE) framework, extending that work in parts and customizing the design to Australian circumstances. Setting, participants and outcome measures The 32 hospitals, containing 119 participating departments, provided wide representation across metropolitan, inner and outer regional Australia. We obtained 31 quality management, 1334 clinician and 857 patient questionnaires, and conducted 2401 medical record reviews and 151 external assessments. External data via a secondary source comprised 14 460 index patient admissions across 14 031 individual patients. Associations between hospital, Emergency Department (ED) and department-level systems and strategies and five patient-level outcomes were assessed: 19 of 165 associations (11.5%) were statistically significant, 12 of 79 positive associations (15.2%) and 7 of 85 negative associations (8.2%). Results We did not find clear relationships between hospital-level quality management systems, ED or department quality strategies and patient-level outcomes. ED-level clinical reviews were related to adherence to clinical practice guidelines for AMI, hip fracture and stroke, but in different directions. The results, when considered alongside the DUQuE results, are suggestive that front line interventions may be more influential than department-level interventions when shaping quality of care and that multi-pronged strategies are needed. Benchmark reports were sent to each participating hospital, stimulating targeted quality improvement activities. Conclusions We found no compelling relationships between the way care is organized and the quality of care across three targeted patient-level outcome conditions. The study was cross-sectional, and thus we recommend that the relationships studied should be assessed for changes across time. Tracking care longitudinally so that quality improvement activities are monitored and fed back to participants is an important initiative that should be given priority as health systems strive to develop their capacity for quality improvement over time.

Abstract. Satellite infra-red emission instruments require efficient systems that can separate and flag observations which are affected by clouds and aerosols. This paper investigates the identification of cloud and aerosols from infra-red, limb sounding spectra recorded by the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS), a high spectral resolution, Fourier transform spectrometer on ENVISAT. Specifically, the performance of an existing cloud and aerosol particle detection method is simulated, with a radiative transfer model, in order to establish for the first time limits to confident detection of particle effects in MIPAS data. The newly established thresholds improve confidence in the ability of MIPAS to detect particle injection events and plume transport in the UTLS as well as better characterised cloud distributions. The method also provides a fast front-end detection system for the MIPClouds processor, a processor designed for the retrieval of macro- and microphysical cloud properties from the MIPAS data. It is shown that across much of the stratosphere, the threshold for the standard cloud index in band A is 5 although values of greater than 6 occur in restricted regimes. Polar regions show a surprising degree of uncertainty at altitudes above 20 km due to potential high ClO formation and also poor signal-to-noise due to low atmosphere temperatures. The optimised thresholds of this study can be used for much of the time, but time/composition dependent thresholds are recommended for MIPAS data for the strongly perturbed polar stratosphere. In the UT, thresholds of 5 apply at 12 km and above but decrease rapidly at lower altitudes. The new thresholds are shown to allow much more sensitive detection of particle distributions in the upper troposphere and lower stratosphere (UTLS), with extinction detection limits above 13 km often better than 10−4 km−1, with values approaching 10−5 km−1 in some cases. Comparisons of the new MIPAS results with data from HIRDLS and CALIOP, outside of the poles, establishes good agreement in distributions (cloud occurrence frequencies and clouds and aerosol top heights) with an offset between MIPAS and the other instruments of 0.5 km between 12 and 20 km. We conclude that current infra-red limb sounders provide a very consistent picture of particles in the UTLS, allowing detection limits which are consistent with the lidar observations. Investigations of the MIPAS data for the Kasatochi volcanic eruption and the Black Saturday fires in Australia are used to exemplify the usefulness of MIPAS limb sounding data for monitoring aerosol injections into the UTLS, and into the stratosphere, in particular over monthly timescales. It is shown that the new thresholds allow such events to be much more effectively monitored from MIPAS with detection limits for these case studies of 1 × 10−5 km−1 at 12 μm.

Background: Achieving system-level, sustainable ‘scale-up’ of interventions is the epitome of successful translation of evidence-based approaches in population health. In physical activity promotion, few evidence-based interventions reach implementation at scale or become embedded within systems for sustainable health impact. This is despite the vast published literature describing efficacy studies of small-scale physical activity interventions. Research into physical activity scale-up (through case-study analysis; evaluations of scale-up processes in implementation trials; and mapping the processes, strategies, and principles for scale-up) has identified barriers and facilitators to intervention expansion. Many interventions are implemented at scale by governments but have not been evaluated or have unpublished evaluation information. Further, few public health interventions have evaluations that reveal the costs and benefits of scaled-up implementation. This lack of economic information introduces an additional element of risk for decision makers when deciding which physical activity interventions should be supported with scarce funding resources. Decision-makers face many other challenges when scaling interventions which do not relate to formal research trials of scale-up; Methods: To explore these issues, a multidisciplinary two-day workshop involving experts in physical activity scale-up was convened by the University of Newcastle, Australia, and the University of Ottawa, Canada (February 2019); Results: In this paper we discuss some of the scale-up tensions (challenges and conflicts) and paradoxes (things that are contrary to expectations) that emerged from this workshop in the context of the current literature and our own experiences in this field. We frame scale-up tensions according to epistemology, methodology, time, and partnerships; and paradoxes as ‘reach without scale’, ‘planned serendipity’ and ‘simple complexity’. We reflect on the implications of these scale-up tensions and paradoxes, providing considerations for future scale-up research and practice moving forward; Conclusions: In this paper, we delve deeper into stakeholders’ assumptions, processes and expectations of scaling up, and challenge in what ways as stakeholders, we all contribute to desired or undesired outcomes. Through a lens of ‘tensions’ and ‘paradoxes’, we make an original contribution to the scale-up literature that might influence current perspectives of scaling-up, provide future approaches for physical activity promotion, and contribute to understanding of dynamic of research-practice partnerships.

Abstract. Satellite infrared emission instruments require efficient systems that can separate and flag observations which are affected by clouds and aerosols. This paper investigates the identification of cloud and aerosols from infrared, limb sounding spectra that were recorded by the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS), a high spectral resolution Fourier transform spectrometer on the European Space Agency's (ESA) ENVISAT (Now inoperative since April 2012 due to loss of contact). Specifically, the performance of an existing cloud and aerosol particle detection method is simulated with a radiative transfer model in order to establish, for the first time, confident detection limits for particle presence in the atmosphere from MIPAS data. The newly established thresholds improve confidence in the ability to detect particle injection events, plume transport in the upper troposphere and lower stratosphere (UTLS) and better characterise cloud distributions utilising MIPAS spectra. The method also provides a fast front-end detection system for the MIPClouds processor; a processor designed for the retrieval of macro- and microphysical cloud properties from the MIPAS data. It is shown that across much of the stratosphere, the threshold for the standard cloud index in band A is 5.0 although threshold values of over 6.0 occur in restricted regimes. Polar regions show a surprising degree of uncertainty at altitudes above 20 km, potentially due to changing stratospheric trace gas concentrations in polar vortex conditions and poor signal-to-noise due to cold atmospheric temperatures. The optimised thresholds of this study can be used for much of the time, but time/composition-dependent thresholds are recommended for MIPAS data for the strongly perturbed polar stratosphere. In the UT, a threshold of 5.0 applies at 12 km and above but decreases rapidly at lower altitudes. The new thresholds are shown to allow much more sensitive detection of particle distributions in the UTLS, with extinction detection limits above 13 km often better than 10−4 km−1, with values approaching 10−5 km−1 in some cases. Comparisons of the new MIPAS results with cloud data from HIRDLS and CALIOP, outside of the poles, establish a good agreement in distributions (cloud and aerosol top heights and occurrence frequencies) with an offset between MIPAS and the other instruments of 0.5 km to 1 km between 12 km and 20 km, consistent with vertical oversampling of extended cloud layers within the MIPAS field of view. We conclude that infrared limb sounders provide a very consistent picture of particles in the UTLS, allowing detection limits which are consistent with the lidar observations. Investigations of MIPAS data for the Mount Kasatochi volcanic eruption on the Aleutian Islands and the Black Saturday fires in Australia are used to exemplify how useful MIPAS limb sounding data were for monitoring aerosol injections into the UTLS. It is shown that the new thresholds allowed such events to be much more effectively derived from MIPAS with detection limits for these case studies of 1 × 10−5 km−1 at a wavelength of 12 μm.

This medal is awarded by the New Zealand Plant Protection Society to honour those who have made exceptional contributions to plantprotection in New Zealand in the widest sense. The medal is awarded for outstanding services to plant protection, whether through research,education, implementation or leadership.
In 2016, the New Zealand Plant Protection Medal was awarded to Dr Rob Beresford who is one of New Zealand’s most experienced and versatile plant pathologists. Rob started his career in science with an MSc Hons, 1st class, in Auckland in 1978 and was appointed to DSIR Plant Diseases Division at Lincoln in 1979. He was awarded a National Research Advisory Council Postgraduate Research Fellowship to undertake PhD studies at Long Ashton Research Station in the UK from1982 to 1985, returning to Lincoln in 1986. Those studies kicked off a long career in epidemiology and today Rob is New Zealand’s pre-eminent plant disease epidemiologist. For 30 years, Rob has been New Zealand’s strongest advocate for the use of weather-based disease prediction for developing practicaldisease control strategies, particularly to reduce the economic, environmental and market residue impacts of fungicide use. By understanding and modelling relationships between pathogen biology and ecology and weather, Rob has translated complex correlations between biological and physical factorsinto simple practical tools for growers to use for disease control. To date, these have included decision support tools for apple scab, downy mildew in onions, botrytis in grapes and more recently Psa in kiwifruit. He has also developed prediction models for climatic risk of invasive pathogens (potato wart disease and myrtle rust) and for the impacts of climate change on crop diseases.
Recognising the importance of climate and weather in affecting plant diseases, Rob has, for many years, championed a network of weather stations in the key horticultural districts throughout New Zealand to generate data for the decision-support tools. It has been a struggle to keep the network running against shortages of funding and the frequent need to re-assert the value of the network to New Zealand horticulture. Rob has built a team of equally committed colleagues who share this understanding and, through tenacity and persistence, have recently achieved an upgrade of the entire network to internet-based communication systems. It is through his close collaborations over many years with the software company HortPlus that his decision support tools have been delivered to the commercial arena.
Rob was a member of the New Zealand team that argued the case at the World Trade Organisation for the easing of restrictions on New Zealand apples entering Australia. Rob’s superior skills in interpreting climate data, in this case Australian data, in terms of pathogen survival, establishment and spread, and his clarity in presenting the results were instrumental in the success of that case in 2010.
In parallel with Rob’s epidemiological strategy to reduce fungicide use is his interest in the threat of pathogens developing resistance to fungicides. Rob leads research to identify resistance threats to fungicides and also provides liaison between grower associations and agrochemical companies to design and implement robust resistance-management strategies. His focus on resistance started in 2005 when he published updated management strategies for all nine of the then available fungicide groups for the New Zealand Plant Protection Society (NZPPS). In 2007, he re-established the New Zealand Committee on Pesticide Resistance (NZCPR) (which had been in abeyance for 10 years) and chaired the committee’s work on fungicides, insecticides and herbicides from 2007 to 2012. He stepped aside to become NZCPR Science Advisor in 2012 so he could focus on resistance research. Following devastating disease outbreaks of apple scab (Venturia ineaqualis) in the pipfruit industry in 2009, Rob initiated a research programme with Pipfruit New Zealand that showed the cause of the outbreaks to be resistance to two groups of fungicides in use at the time. He has recently coordinated resistance strategy updates for botrytis affecting the wine industry, for summer fruit diseases and is currently leading a programme to monitor resistance of grape powdery mildew to key groups of fungicides. Rob was awarded the 2014 Plant & Food Research Chairman’s Award for his work on fungicide resistance.
Rob is an effective communicator at all levels from heavy science to grower forums and is always willing to share his time, skills and knowledge. He has been involved with undergraduate lecturing for many years and has successfully supervised several PhDs.

Introduction:While medicines and medical tests are developed in a controlled clinical trial environment, postmarketing surveillance in the real world can be challenging. MedicineInsight—a database of longitudinal patient-level clinical information from primary care practices in Australia—is a novel program that collects primary care data to improve postmarketing surveillance at a national level.Methods:MedicineInsight collects de-identified clinical information from primary care practice information systems using data extraction tools. MedicineInsight currently includes 3.6 million regular patients of 3,300 family physicians (general practitioners) from 650 primary care practices across Australia. MedicineInsight data include longitudinal clinical information on diagnosis and medicines (dose, strength, route of administration, medication switches over time, adverse events, and allergies), and pathology testing data. A series of observational studies was developed for postmarketing surveillance of management of a range of health priorities including type 2 diabetes mellitus (T2DM), chronic obstructive pulmonary disease (COPD), depression, and antibiotics use.Results:Forty-four percent of patients with T2DM in the MedicineInsight database did not have a recorded hemoglobin A1c result and thirty-one percent did not have a recorded blood pressure reading in the previous 6 months. While guidelines recommend a stepwise approach to the initiation of COPD therapy, forty-nine percent of patients with COPD (with or without asthma) were prescribed dual therapy at initiation and a small number (4.5 percent) were prescribed triple therapy. Between 2011 and 2015, the annual rate of antidepressant prescribing per 1,000 family physician encounters increased by eight percent. High volumes of antibiotics were prescribed for respiratory tract infections in Australian primary care, notwithstanding guideline recommendations that antibiotics are not recommended in most cases.Conclusions:Large scale, real-world clinical data from primary care practices can play an important role in postmarketing surveillance at a national level.

PurposeThe purpose of this paper is to provide a labour process theory interpretation of four case studies within the Australian construction industry. In each case study a working time intervention (a shift to a five‐day working week from the industry standard six days) was implemented as an attempt to improve the work‐life balance of employees.Design/methodology/approachThis paper was based on four case studies with mixed methods. Each case study has a variety of data collection methods which include questionnaires, short and long interviews, and focus groups.FindingsIt was found that the complex mix of wage‐ and salary‐earning staff within the construction industry, along with labour market pressures, means that changing to a five‐day working week is quite a radical notion within the industry. However, there are some organisations willing to explore opportunities for change with mixed experiences.Practical implicationsThe practical implications of this research include understanding the complexity within the Australian construction industry, based around hours of work and pay systems. Decision‐makers within the construction industry must recognize a range of competing pressures that mean that “preferred” managerial styles might not be appropriate.Originality/valueThis paper shows that construction firms must take an active approach to reducing the culture of long working hours. This can only be achieved by addressing issues of project timelines and budgets and assuring that take‐home pay is not reliant on long hours of overtime.

Full textAbstract:
In Australia, the incidence of cancer diagnoses is rising along with an aging population. Cancer treatments, such as chemotherapy, are increasingly being provided in the ambulatory care setting. Cancer treatments are commonly associated with distressing and serious sideeffects and patients often struggle to manage these themselves without specialized real-time support. Unlike chronic disease populations, few systems for the remote real-time monitoring of cancer patients have been reported. However, several prototype systems have been developed and have received favorable reports. This review aimed to identify and detail systems that reported statistical analyses of changes in patient clinical outcomes, health care system usage or health economic analyses. Five papers were identified that met these criteria. There was wide variation in the design of the monitoring systems in terms of data input method, clinician alerting and response, groups of patients targeted and clinical outcomes measured. The majority of studies had significant methodological weaknesses. These included no control group comparisons, small sample sizes, poor documentation of clinical interventions or measures of adherence to the monitoring systems. In spite of the limitations, promising results emerged in terms of improved clinical outcomes (<em>e.g.</em> pain, depression, fatigue). Health care system usage was assessed in two papers with inconsistent results. No studies included health economic analyses. The diversity in systems described, outcomes measured and methodological issues all limited between-study comparisons. Given the acceptability of remote monitoring and the promising outcomes from the few studies analyzing patient or health care system outcomes, future research is needed to rigorously trial these systems to enable greater patient support and safety in the ambulatory setting.

Purpose – The purpose of this paper is to describe the implementation of 3D printing and maker spaces in various library settings. Insights, challenges, successes, projects as well as recommendations will be shared. Commonalities across libraries 3D printing technologies and maker space learning areas will also explored. Design/methodology/approach – This paper delves into six case studies of librarians that have implemented 3D printers and/or maker spaces in their libraries. The case studies focus on libraries at three different levels: school, public, and higher education with two case studies from each type. The author of this paper will describe the cases, projects, challenges, successes, along with other aspects of 3D printer, and maker space integration. Findings – 3D printing and maker spaces, while very popular in the field of librarianship can be incredibly exciting to implement but they come with challenges and successes just like any type of new technology. Librarians have to be fearless in implementing this technology, willing to learn on their feet, and be excited to explore. Originality/value – At this time most publications on 3D printing are held in the realm of popular publications (blogs, magazines, zines, etc.). Very little has been written on a wider range of case studies where 3D printers and maker spaces have been integrated into libraries of various types. This paper sets the foundation for further exploration in how 3D printing and maker spaces could be a part of library services.

PurposeContinuous quality improvement (CQI) programmes have been taken up widely by indigenous primary health care services in Australia, but as yet there has not been a systematic assessment of their focus and achievements. A scoping review of the literature from studies of CQI in indigenous primary health care services was undertaken to explore impacts on service systems, care and client outcomes with the aim of providing guidance on future evaluation efforts. The paper aims to discuss these issues,Design/methodology/approachSearches were conducted in MEDLINE, CINAHL and the Cochrane Database of Systematic Reviews to December 2016 and handsearching of key websites and publications. Studies of CQI programs or activities in Indigenous primary health care services which demonstrated some combination of CQI characteristics, as described by Rubenstein (2013) were included. A two-stage approach to analysis was undertaken. Stage 1 identified the range and scope of literature, and Stage 2 investigated impacts to service systems, care and client outcomes. The Framework for Performance Assessment in Primary Health Care was used to frame the Stage 2 analysis.FindingsThe majority of Aboriginal community controlled health services have been involved in CQI but there are gaps in knowledge about uptake in general practice and government clinics. There are as many baseline studies as studies on impacts over time. Of the 14 studies included for further analysis, 6 reported on impacts on service systems; all 14 reported on impacts on care and 6 on client outcomes. Changes to services systems are variable and studies of impacts on care and client outcomes show promising though uneven improvements. There are no economic studies or studies addressing community engagement in CQI activities.Research limitations/implicationsTo supplement existing limited knowledge about which service system change strategies are effective and sustainable for which problems in which settings, there needs to be investment in research and development. Research needs to be grounded in the realities of service delivery and contribute to the development of CQI capacity at the service level. Knowledge translation needs to be built into implementation to ensure maximum benefit to those endeavouring on a daily basis to constantly reflect on and improve the quality of the care they deliver to clients, and to the stewardship structures supporting services at regional, state/territory and national levels.Practical implicationsImproved approaches, methods, data capture and reporting arrangements are needed to enhance existing activity and to ensure maximum benefit to services endeavouring to reflect on and improve quality of care and to the stewardship structure supporting services at regional, state/territory and national levels.Originality/valueAlthough there is a growing body of research evidence about CQI both nationally and internationally, and considerable investment by the federal government in Australia to support CQI as part of routine practice, there has not been a systematic assessment of the achievements of CQI in Indigenous primary health care services. Many unanswered questions remain about the extent of uptake, implementation and impacts. This is a barrier to future investment and regional and local programme design, monitoring and evaluation. The authors conducted a scoping review to address these questions. From this, the authors draw conclusions about the state of knowledge in Australia with a view to informing how future CQI research and evaluation might be intensified.

ObjectiveThe aim of this study was to describe timelines and challenges encountered in obtaining ethics and governance approvals for an Australian multicentre audit study involving 100 public (n=22) and private (n=78) sites from three health sectors and all eight Australian states and territories. MethodsWe determined and compared the processes, documentation and number of business days required to prepare applications and obtain research ethics and governance approvals. ResultsIn total, the full ethics and governance process (calculated from the date the first application was started to the date the final approval was granted) took 203 business days (79% of the study timeline). Standard risk ethics applications (n=4) took a median of 17 business days (range 3–35 days) to prepare and 32 business days (range 17–67 days) to be approved; expedited ethics applications (n=4) took a median of 5 business days (range 1–20 days) to prepare and 10 business days (range 1–44 days) to be approved. Governance approvals (n=23) took a median of 27 business days (range 4–63 days) to prepare and 20 business days (range 4–61 days) to be approved. Challenges included the lack of a nationwide single-site ethical review process, the extensive time required to duplicate content across applications, variability in application requirements and submission systems, and contract negotiations. ConclusionFurther improvements are needed to reduce duplication and increase the efficiency of Australian ethics and governance review processes. What is known about the topic?The process for obtaining ethics approval for multicentre research has been streamlined through the introduction of single-site ethics review. However, the process of gaining ethics and governance approvals for national multicentre research continues to be time-consuming, resource-intensive and duplicative. What does this paper add?This is the first study to examine the challenges of obtaining ethics and governance approvals for a non-interventional multicentre study involving three health sectors (hospital, aged care, general practice), both private and public services and all eight Australian jurisdictions. Previous examinations of Australian multicentre studies have considered only one health sector, focused on the public system and/or were not national in scope. What are the implications for practitioners?Researchers and funders need to be aware of the considerable time, resources and costs involved in gaining research ethics and governance approvals for multicentre studies and include this in budgets and study timelines. Policy makers and administrators of ethics and governance review processes must address barriers to conducting multicentre research in Australia.

Full textAbstract:
The emerging ‘grand challenges’ of climate change, resource scarcity and population growth present a risk nexus to cities in the Anthropocene. This article discusses the potential that rapid urbanisation presents to help mitigate these risks through large-scale transitions if future urban development is delivered using evidence-based policies that promote regenerative urban outcomes (e.g. decarbonising energy, recycling water and waste, generating local food, integrating biodiversity). Observations from an Australian case study are used to describe urban governance approaches capable of supporting regenerative urbanism. The regenerative urbanism concept is associated with macro-scale urban and transport planning that shapes different urban fabrics (walking, transit, automobile), as the underlying infrastructure of each fabric exhibits a different performance, with automobile fabric being the least regenerative. Supporting urban systems based upon regenerative design principles at different scales (macro, meso and micro) can deliver deep and dramatic outcomes for not just reducing the impact of the grand challenges but turning them into regenerative change. In combination, these approaches form the cornerstone of regenerative cities that can address the grand challenges of the Anthropocene, while simultaneously improving livability and urban productivity to foster human flourishing.

In this manner, we introduce a methodology for detecting chaotic behavior in FO systems through the analysis of Poincaré maps. The optimization process is performed applying differential evolution (DE) and accelerated particle swarm optimization (APSO) algorithms for maximizing the Kaplan-Yorke dimension ($ D_{KY} $) of two case studies: a 3D and a 4D FO chaotic systems with hidden attractors. These FO chaotic systems are solved applying the Grünwald-Letnikov method, and the Numba just-in-time (jit) compiler is used to improve the optimization process's time execution in Python programming language. The optimization results show that the proposed method efficiently optimizes FO chaotic systems with hidden attractors while saving execution time.</p></abstract>

Abstract Background Queensland, Australia has been successful in containing the COVID-19 pandemic. Underpinning that response has been a highly effective virus containment strategy which relies on identification, isolation, and contact tracing of cases. The dramatic emergence of the COVID-19 pandemic rendered traditional paper-based systems for managing contact tracing no longer fit for purpose. A rapid digital transformation of the public health contact tracing system occurred to support this effort. Objectives The objectives of the digital transformation were to shift legacy systems (paper or standalone electronic systems) to a digitally enabled public health system, where data are centered around the consumer rather than isolated databases. The objective of this paper is to outline this case study and detail the lessons learnt to inform and give confidence to others contemplating digitization of public health systems in response to the COVID-19 pandemic. Methods This case study is set in Queensland, Australia. Universal health care is available. A multidisciplinary team was established consisting of clinical informaticians, developers, data strategists, and health information managers. An agile “pair-programming” approach was undertaken to application development and extensive change efforts were made to maximize adoption of the new digital workflows. Data governance and flows were changed to support rapid management of the pandemic. Results The digital coronavirus application (DCOVA) is a web-based application that securely captures information about people required to quarantine and creates a multiagency secure database to support a successful containment strategy. Conclusion Most of the literature surrounding digital transformation allows time for significant consultation, which was simply not possible under crisis conditions. Our observation is that staff was willing to adopt new digital systems because the reason for change (the COVID-19 pandemic) was clearly pressing. This case study highlights just how critical a unified purpose, is to successful, rapid digital transformation.

Full textAbstract:
Objectives. To analyse the short- and long-term costs and benefits of alternative models of primary care for the management of patients with type 2 diabetes in Australia. The models of care reflect differential uptake of primary care-based incentive programs, including reminder systems and involvement of practice nurses in management. This paper describes our study protocol and its progress. Methods. We are undertaking an observational study using a cluster sample design that links retrospective patient data from a range of sources to estimate costs and intermediate outcomes (such as the level of glycosylated haemoglobin (HbA1c)) over a 3-year time horizon. We use the short-term data as a basis to estimate lifetime costs and benefits of alternative models of care using a decision analytic model. Initial report. We recruited 15 practices from a metropolitan area (Adelaide) and allocated them to three models of care. Three hundred and ninety-nine patients agreed to participate. We use multilevel analysis to evaluate the association between different models of care and patient-level outcomes, while controlling for several covariates. Discussion/conclusions. Given the large amount of funding currently used to maintain primary care-based incentives in general practices in Australia, the results of this study generate the knowledge required to promote investment in the most cost-effective incentives. What is known about the topic? Collaborative models of care can improve the outcomes in patients with chronic diseases such as type 2 diabetes (T2D), and the large amount of funding is currently used to maintain primary care-based initiatives to provide incentives for general practices to take a more multidisciplinary approach in management of chronic diseases. What does this paper add? There are few model-based studies of the cost-effectiveness of alternative models of care defined on the basis of the uptake of financial incentives within Australian primary care settings for diabetes management. Using routinely collected data, this project evaluates the effectiveness of alternative models of care and estimates long-term costs and benefits of various models of care. What are the implications for practitioners? This study explores opportunities for the use of linked, routinely collected data to evaluate clinical practice, and identifies the optimal model of care in management of patients with T2D, with respect to differences in long-term costs and outcomes.

AbstractWestern boundary currents (WBCs) are highly variable narrow meandering jets, making assessment of their volume transports a complex task. The required high-resolution temporal and spatial measurements are available only at a limited number of sites. In this study a method is developed for improving estimates of the East Australian Current (EAC) mean transport and its low-frequency variability, using complementary modern datasets. The present calculation is a case study that will be extended to other subtropical WBCs. The method developed in this work will reduce uncertainties in estimates of the WBC volume transport and in the interannual mass and heat budgets of the meridional overturning circulations, improving our understanding of the response of WBCs to local and remote forcing on long time scales. High-resolution expendable bathythermograph (HR-XBT) profiles collected along a transect crossing the EAC system near Brisbane, Australia, are merged with coexisting profiles and parking-depth trajectories from Argo floats, and with altimetric sea surface height data. Using HR-XBT/Argo/altimetry data combined with Argo trajectory-based velocities at 1000 m, the 2004–15 mean poleward alongshore transport of the EAC is 19.5 ± 2.0 Sv (1 Sv ≡ 106 m3 s−1) of which 2.5 ± 0.5 Sv recirculate equatorward just offshore of the EAC. These transport estimates are consistent in their mean and variability with concurrent and nearly collocated moored observations at 27°S, and with earlier moored observations along 30°S. Geostrophic transport anomalies in the EAC system, including the EAC recirculation, show a standard deviation of ±3.1 Sv at interannual time scales between 2004 and 2015.

Two recent studies of the health effects of vegetarian diets reported conflicting results: the EPIC-Oxford study reported a significant increase in strokes among vegetarians compared to meat-eaters among a predominantly Caucasian cohort, while another, performed on Taiwanese Buddhists, reported significantly lower incidence of strokes among vegetarians. This was doubly puzzling given the pronounced decrease in cardiovascular events among the EPIC-Oxford group. In this article, we make a detailed comparison of the actual dietary intake of various food groups by the cohorts in these studies. We then use the nutritional principles of Ayurveda—traditional Indian medicine—to show how these apparently contradictory results may be explained. Systems of traditional medicine such as Ayurveda possess profound knowledge of the effects of food on physiology. Ayurveda takes into account not just the type of food, but also multiple other factors such as taste, temperature, and time of consumption. Traditional cuisines have evolved hand in hand with such systems of medicine to optimize nutrition in the context of local climate and food availability. Harnessing the experiential wisdom of these traditional systems to create an integrative nutrition science would help fight the ongoing epidemic of chronic lifestyle diseases, and improve health and wellness.

Purpose – The purpose of this paper is to describe the emergence of the mobile library FabLab FryskLab, a project of Bibliotheekservice Fryslân (BSF). There will be special attention on how the business case has been established. Design/methodology/approach – The author examines the broader development of (mobile) FabLabs in libraries. Based on the description of sub-projects that together make the project FryskLab the approach of BSF is described. Findings – The design of a mobile library lab speaks to many people’s imagination. However, achieving a sound business case requires a lot more than just driving around in a bus and providing practical workshops. Developing supporting projects is necessary. Originality/value – At this time most publications on mobile library makerspaces are held in the realm of popular publications (blogs, magazines). Very little has been written on a wider range of case studies where mobile library makerspaces have been integrated into library services. This paper serves as an insight on how BSF developed the FryskLab project.

New management techniques (NMTs) associated with `lean production' - teamworking; just-in-time (JIT) systems; continuous improvement (kaizen); zero defects and so on - have become increasingly influential, particularly in the car industry. This paper reports on case studies and a questionnaire survey of workers in UK and US auto firms operating in Britain. Trade unions have had a significant, albeit variable, impact on the introduction of NMTs. However, not only do the workers have an incomplete perception of the nature of NMTs, but those they do experience would seem to result in an intensification of work, rather than `smarter' work as predicted by the protagonists of NMTs.

The licensing and regulation of physicians is an important topic worldwide and is often tied to discussions in various countries of health care system reform. We conducted a review of current practices for regulating physicians as a key group of health care professionals in eight jurisdictions in Asia and other parts of the world in order to draw implications for the development of future regulatory policies in Hong Kong. Jurisdictions studied included Australia, Canada, China, Malaysia, New Zealand, Singapore, the United Kingdom and the United States. A literature search, supplemented by interviews, was conducted. In analyzing information gathered about global regulatory systems, we used a framework for comparing regulatory typology, developed by the RAND Europe research institute. Our review found that the jurisdictions studied exhibited both similarities and differences in terms of how physicians are regulated and by whom. As a result of our search, we were able to identify 10 key trends in international medical regulation of importance to Hong Kong as it considers reforms to its health care system overall:Changes in medical regulation are seen as a way of improving the quality of patient care.Reform of medical regulation often requires government legislation.The creation of common principles for policies, structures and the organization of regulation between professions is an emerging practice.The involvement of lay people on boards and in inquiries is increasingly common.Medical regulation is moving away from models of self-regulation and toward regulatory models that emphasize partnership between professions and the public, physicians and patients.Health care providers and institutional regulators play complementary roles in medical regulation.Regulation impacts the quality of care — not just the detection and remediation of poor performance.Investigatory and disciplinary functions are increasingly separated and organized independently of each other.Continuous Professional Development (CPD) is compulsory for physicians in many jurisdictions.Overseas medical graduates are admitted into practice in different ways from country to country. These trends are important for regulators in all countries to note as they assess the basic structure and effectiveness of their own medical regulatory systems.

Objectives. This paper describes the longitudinal component of a larger mixed methods study into the processes and outcomes of chronic condition management and self-management strategies implemented in three Aboriginal communities in South Australia. The study was designed to document the connection between the application of structured systems of care for Aboriginal people and their longer-term health status. Methods. The study concentrated on three diverse Aboriginal communities in South Australia; the Port Lincoln Aboriginal Health Service, the Riverland community, and Nunkuwarrin Yunti Aboriginal Health Service in the Adelaide metropolitan area. Repeated-measure clinical data were collected for individual participants using a range of clinical indicators for diabetes (type 1 and 2) and related chronic conditions. Clinical data were analysed using random effects modelling techniques with changes in key clinical indicators being modelled at both the individual and group levels. Results. Where care planning has been in place longer than in other sites overall improvements were noted in BMI, cholesterol (high density and low density lipids) and HbA1c. These results indicate that for Aboriginal patients with complex chronic conditions, participation in and adherence to structured care planning and self-management strategies can contribute to improved overall health status and health outcomes. Conclusions. The outcomes reported here represent an initial and important step in quantifying the health benefits that can accrue for Aboriginal people living with complex chronic conditions such as diabetes, heart disease and respiratory disease. The study highlights the benefits of developing long-term working relationships with Aboriginal communities as a basis for conducting effective collaborative health research programs. What is known about the topic? Chronic condition management and self-management programs have been available to Aboriginal people in a range of forms for some time. We know that some groups of patients are keen to engage with care planning and self-management protocols and we have anecdotal evidence of this engagement leading to improved quality of life and health outcomes for Aboriginal people. What does this paper add? This paper provides early evidence of sustained improvement over time for a cohort of Aboriginal people who are learning to deal with a range of chronic illnesses through accessing structured systems of support and care. What are the implications for practitioners? This longitudinal evidence of improved outcomes for Aboriginal people is encouraging and should lead on to more definitive studies of outcomes accruing for people engaged in structured systems of care. Not only does this finding have implications for the overall management of chronic illness in Aboriginal communities, but it points the way to how health services might best invest their resources and efforts to improve the health status of people with chronic conditions and, in the process, close the gap between the life expectancy of Aboriginal people and that of other community groups in Australia.
