Heritage & habitus : designing to support situated, living knowledge

We refer to an ongoing endeavour aimed to assist Indigenouscommunities in Australian in persisting their personal and cultural memories linked to temporally dynamic interactions in situ. The design enables Indigenous users to upload items they collect themselves (e.g. photographs, audio, video) using mobile phones,in their traditional lands into a topographical simulation; and, thento associate these items with their own hand-drawn markings inthe simulation. The design responds to the rich interconnectedness between Indigenous culture and the land and the need to converge spatial information technologies with practices that are not, inherently, conditioned by the geometries of the West. We propose that the design approach contributes to thinking about ways that mobile guides can respond to multiple realities and corporeal and affective phenomena.

Agreement between temporal and spatial gait parameters from an instrumented walkway and treadmill system at matched walking speed

Background Commercially available instrumented treadmill systems that provide continuous measures of temporospatial gait parameters have recently become available for clinical gait analysis. This study evaluated the level of agreement between temporospatial gait parameters derived from a new instrumented treadmill, which incorporated a capacitance-based pressure array, with those measured by a conventional instrumented walkway (criterion standard). Methods Temporospatial gait parameters were estimated from 39 healthy adults while walking over an instrumented walkway (GAITRite®) and instrumented treadmill system (Zebris) at matched speed. Differences in temporospatial parameters derived from the two systems were evaluated using repeated measures ANOVA models. Pearson-product-moment correlations were used to investigate relationships between variables measured by each system. Agreement was assessed by calculating the bias and 95% limits of agreement. Results All temporospatial parameters measured via the instrumented walkway were significantly different from those obtained from the instrumented treadmill (P < .01). Temporospatial parameters derived from the two systems were highly correlated (r, 0.79–0.95). The 95% limits of agreement for temporal parameters were typically less than ±2% of gait cycle duration. However, 95% limits of agreement for spatial measures were as much as ±5 cm. Conclusions Differences in temporospatial parameters between systems were small but statistically significant and of similar magnitude to changes reported between shod and unshod gait in healthy young adults. Temporospatial parameters derived from an instrumented treadmill, therefore, are not representative of those obtained from an instrumented walkway and should not be interpreted with reference to literature on overground walking.

Multiple types of data are required to identify the mechanisms influencing the spatial expansion of melanoma cell colonies

Background The expansion of cell colonies is driven by a delicate balance of several mechanisms including cell motility, cell-to-cell adhesion and cell proliferation. New approaches that can be used to independently identify and quantify the role of each mechanism will help us understand how each mechanism contributes to the expansion process. Standard mathematical modelling approaches to describe such cell colony expansion typically neglect cell-to-cell adhesion, despite the fact that cell-to-cell adhesion is thought to play an important role. Results We use a combined experimental and mathematical modelling approach to determine the cell diffusivity, D, cell-to-cell adhesion strength, q, and cell proliferation rate, ?, in an expanding colony of MM127 melanoma cells. Using a circular barrier assay, we extract several types of experimental data and use a mathematical model to independently estimate D, q and ?. In our first set of experiments, we suppress cell proliferation and analyse three different types of data to estimate D and q. We find that standard types of data, such as the area enclosed by the leading edge of the expanding colony and more detailed cell density profiles throughout the expanding colony, does not provide sufficient information to uniquely identify D and q. We find that additional data relating to the degree of cell-to-cell clustering is required to provide independent estimates of q, and in turn D. In our second set of experiments, where proliferation is not suppressed, we use data describing temporal changes in cell density to determine the cell proliferation rate. In summary, we find that our experiments are best described using the range D = 161 - 243 ?m2 hour-1, q = 0.3 - 0.5 (low to moderate strength) and ? = 0.0305 - 0.0398 hour-1, and with these parameters we can accurately predict the temporal variations in the spatial extent and cell density profile throughout the expanding melanoma cell colony. Conclusions Our systematic approach to identify the cell diffusivity, cell-to-cell adhesion strength and cell proliferation rate highlights the importance of integrating multiple types of data to accurately quantify the factors influencing the spatial expansion of melanoma cell colonies.

Residential real estate education and globalisation in Australian real estate markets and practices

The purpose of this scoping paper is to offer an overview of the literature to determine the development to date in the area of residential real estate agency academic and career education in respect to Foreign Direct Investment (FDI) transactions and implications in Australia. This paper will review studies on the issue of foreign real estate ownership and FDI in Australian real estate markets to develop an understanding of the current state of knowledge on residential real estate agency practice, career education and real estate licensing requirements in Australia. The distinction between the real estate profession education, compared to other professions such as accounting, legal and finance is based on the intensity of the professional career training prior or post formal academic training. Real estate education could be carried out with relatively higher standards in terms of licensing requirement, career and academic education. As FDI in the Australian real estate market is a complex globalisation and economic phenomenon, a simple content of residential real estate training and education may not promote proper management or capacity in dealing with relevant foreign residential property market transaction. The preliminary summarising from the literature of residential real estate agency education, with its current relevant or emerging licensing requirement are focused on its role and effectiveness and impact in residential real estate market. Particular focus will be directed to the FDI relevant residential real estate agency transactions and practices, which have been strongly influenced by the current residential real estate market and agency practices. Taken together, there are many opportunities for future research to extend our understanding and improving the residential real estate agency education and training of Foreign Direct Investment in the Australian residential real estate sector.

A proposed approach to monitor private-sector policies and practices related to food environments, obesity and non-communicable disease prevention

Private-sector organizations play a critical role in shaping the food environments of individuals and populations. However, there is currently very limited independent monitoring of private-sector actions related to food environments. This paper reviews previous efforts to monitor the private sector in this area, and outlines a proposed approach to monitor private-sector policies and practices related to food environments, and their influence on obesity and non-communicable disease (NCD) prevention. A step-wise approach to data collection is recommended, in which the first (‘minimal’) step is the collation of publicly available food and nutrition-related policies of selected private-sector organizations. The second (‘expanded’) step assesses the nutritional composition of each organization's products, their promotions to children, their labelling practices, and the accessibility, availability and affordability of their products. The third (‘optimal’) step includes data on other commercial activities that may influence food environments, such as political lobbying and corporate philanthropy. The proposed approach will be further developed and piloted in countries of varying size and income levels. There is potential for this approach to enable national and international benchmarking of private-sector policies and practices, and to inform efforts to hold the private sector to account for their role in obesity and NCD prevention.

A point prevalence study of cancer nursing practices for managing intravascular devices in an Australian tertiary cancer center

Purpose The use of intravascular devices is associated with a number of potential complications. Despite a number of evidence-based clinical guidelines in this area, there continues to be nursing practice discrepancies. This study aims to examine nursing practice in a cancer care setting to identify nursing practice and areas for improvement respective to best available evidence. Methods A point prevalence survey was undertaken in a tertiary cancer care centre in Queensland, Australia. On a randomly selected day, four nurses assessed intravascular device related nursing practices and collected data using a standardized survey tool. Results 58 inpatients (100%) were assessed. Forty-eight (83%) had a device in situ, comprising 14 Peripheral Intravenous Catheters (29.2%), 14 Peripherally Inserted Central Catheters (29.2%), 14 Hickman catheters (29.2%) and six Port-a-Caths (12.4%). Suboptimal outcomes such as incidences of local site complications, incorrect/inadequate documentation, lack of flushing orders, and unclean/non intact dressings were observed. Conclusions This study has highlighted a number of intravascular device related nursing practice discrepancies compared with current hospital policy. Education and other implementation strategies can be applied to improve nursing practice. Following education strategies, it will be valuable to repeat this survey on a regular basis to provide feedback to nursing staff and implement strategies to improve practice. More research is required to provide evidence to clinical practice with regards to intravascular device related consumables, flushing technique and protocols.

Weibo, framing, and media practices in China

This study uses frames analysis to investigate online discourses and processes of political deliberation on China’s weibo (microblog) service. It offers a comparative analysis of competing discourses surrounding the case of Wang Yue, a toddler who was ran over by two motor vehicles in Foshan, following which eighteen people passed by and ignored her plight. The study aims to understand how weibo facilitate its users to express their differences and deliberate disagreements with each other. The study found that Internet users are rational in the sense that they do not simply lean towards a dichotomised choice of ‘pro-’ or ‘anti-’ official discourse, but they are able to negotiate their moral choices by considering a wide range of social and political factors in such an emotional and morally controversial incident.

Moderation practices in a faculty of education : the four discourse model

Moderation of student assessment is a critical component of teaching and learning in contemporary universities. In Australia, moderation is mandated through university policies and through the new national university accreditation authority, Tertiary Education Quality and Standards Agency which began operations in late January 2012 (TEQSA, 2012). The TEQSA requirement to declare details of moderation and any other arrangements used to support consistency and reliability of assessment and grading across each subject in the course of study is a radical step intended to move toward heightened accountability and greater transparency in the tertiary sector as well as entrenching evidence-based practice in the management of Australian academic programs. In light of this reform, the purpose of this project was to investigate and analyse current moderation practices operating within a faculty of education at a large urban university in Queensland, Australia. This qualitative study involved interviews with the unit coordinators (n=21) and tutors (n=8) of core undergraduate education units and graduate diploma units within the faculty. Four distinct discourses of moderation that academics drew on to discuss their practices were identified in the study. These were: equity, justification, community building, and accountability. These discourses, together with recommendations for changes to moderation practices are discussed in this paper.

The impact of spatial scales and spatial smoothing on the outcome of Bayesian spatial model

Discretization of a geographical region is quite common in spatial analysis. There have been few studies into the impact of different geographical scales on the outcome of spatial models for different spatial patterns. This study aims to investigate the impact of spatial scales and spatial smoothing on the outcomes of modelling spatial point-based data. Given a spatial point-based dataset (such as occurrence of a disease), we study the geographical variation of residual disease risk using regular grid cells. The individual disease risk is modelled using a logistic model with the inclusion of spatially unstructured and/or spatially structured random effects. Three spatial smoothness priors for the spatially structured component are employed in modelling, namely an intrinsic Gaussian Markov random field, a second-order random walk on a lattice, and a Gaussian field with Matern correlation function. We investigate how changes in grid cell size affect model outcomes under different spatial structures and different smoothness priors for the spatial component. A realistic example (the Humberside data) is analyzed and a simulation study is described. Bayesian computation is carried out using an integrated nested Laplace approximation. The results suggest that the performance and predictive capacity of the spatial models improve as the grid cell size decreases for certain spatial structures. It also appears that different spatial smoothness priors should be applied for different patterns of point data.

Assessing land-use and transport integration via a spatial composite indexing model

Achieving sustainable urban development is identified as one ultimate goal of many contemporary planning endeavours and has become central to formulation of urban planning policies. Within this concept, land-use and transport integration is highlighted as one of the most important and attainable policy objectives. In many cities, integration is embraced as an integral part of local development plans, and a number of key integration principles are identified. However, the lack of available evaluation methods to measure extent of urban sustainability levels prevents successful implementation of these principles. This paper introduces a new indicator-based spatial composite indexing model developed to measure sustainability performance of urban settings by taking into account land-use and transport integration principles. Model indicators are chosen via a thorough selection process in line with key principles of land-use and transport integration. These indicators are grouped into categories and themes according to their topical relevance. These indicators are then aggregated to form a spatial composite index to portray an overview of the sustainability performance of the pilot study area used for model demonstration. The study results revealed that the model is a practical instrument for evaluating success of local integration policies and visualizing sustainability performance of built environments and useful in both identifying problematic areas as well as formulating policy interventions.

Urban acupuncture: Hybrid social and technological practices for hyperlocal placemaking

This paper considers an emerging planning practice that uses networked connections to interact with urban places and re-create enlivened cities. The paper presents “urban acupuncture” as a new planning approach that broadens communication and strategically targets interventions across the city. Defined as an approach, which, through the use of digital social networks and interactions, involves citizens and planners in place activations in order to stimulate and reinvigorate place, thus creating meaningful relationships between citizens and their urban settings. This paper uses the UR[BNE] Brisbane Festival 2012 as a qualitative case study of urban acupuncture, best defined as a hyper-localized healing treatment through place activation to enliven and recreate cities. It examines the challenges faced and opportunities embraced by a network of urban professionals. Their aim was to activate the underused urban spaces of central Brisbane through the festival's activities and events. The findings identify the key elements required to design public spaces using socially and technologically networked interactions.

Asking for it? Practices and structures that perpetuate employee silence in pursuing customised work arrangements

A component of broader scholarship addressing the social context in which individuals work, has focused on the role of ‘employee voice’ in determining flexible-work outcomes (Donnelly et al., 2012). Employee voice incorporates a spectrum of practices designed to give employees a say in organisational decisions (Dundon et al., 2004). This paper extends work on voice and workplace flexibility in two ways. First, it focuses not simply on ‘voice’ but on its antithesis, employee silence, which is defined (following Van Dyne et al., 2003) as the intentional withholding of ideas and opinions. We utilise an alternative reading of silence to the majority of literature which interprets it as a product of employee motivation, by focusing on the role of management and by adopting a framework which considers silence as a control dialectic (Donaghey et al., 2011). Second, the study examines silence with respect to preferences for customising the terms/conditions of employment beyond narrowly defined notions of ‘flexible work’ (e.g., reduced hours; home-working). The study utilises 30 telephone interviews with employees who had been previously identified as ‘discontent non-requesters’ (Skinner and Pocock, 2011: 75), that is they had expressed a desire to request flexible working provisions, but had not done so. Interviewees were asked to articulate the reasons for, and consequences of, their silence. The findings reveal nuanced workplace practices and structures that close down possibilities for employee voice and perpetuate silence on matters relating to customising work. They also illustrate a disjuncture between espoused organizational goals and everyday practices and norms encountered in workplaces.

Fever management in children : Vietnamese parents' and paediatric nurses' knowledge, beliefs and practices

This thesis comprised two studies: an exploratory study and a cross-sectional survey, guided by the Theory of Planned Behaviour. It explored parents' and paediatric nurses' knowledge, beliefs and practices about fever management in Vietnam. The research highlights the determinants of parents' and nurses' intentions to manage childhood fever which can be targeted for future interventions to integrate latest evidence-based practices.

An exploratory study of child-feeding practices of Indian mothers with children aged 1-5 years residing in Australia and Mumbai, India

This research has taken the first step to study child-feeding practices of Indian mothers in relation to childhood obesity. It compares feeding practices of Indian mothers with children aged 1-5 years living in Australia and Mumbai. Mothers in the Australian sample were more likely to use 'positive' feeding practices hypothesized to promote healthy growth and weight status. However, mothers in both samples commonly used coercive feeding practices that potentially increase the risk of childhood obesity. These results will inform interventions designed to promote healthy weight status in this cultural group.
