More towards the centre : searching for field position for student equity in Australian higher education

The field of Australian higher education has changed, is changing and is about to change, as it is repositioned in relation to other ‘fields of power’. It is a sector now well defined by its institutional groupings – the Go8, the IRUs, the ATN and the rest – and by their relative claims to selectivity and exclusivity, with every suggestion of their differentiation growing. Even within these groupings there are distinctions and variations. Moreover, Australian universities now compete within an international higher education marketplace, ranked by THES and Shanghai Jiao Tiong league tables. ‘Catchment areas’ and knowledge production have become global. And the potential of a ‘joined‐up’ tertiary education system, of VET and universities, will rework relations within Australian higher education, as will lifting the volume caps on university student numbers. In sum, Australian universities (and agents within them) are positioned differently in the field, although not in the stable relations imagined by Pierre Bourdieu in the France of the 1960s. And being so variously and variably placed, institutions and agents have different stances available to them, including the positions they can take on student equity. In this paper I begin from the premise that our current shared stance on this has been out‐positioned. Nation‐bound proportional representation loses its equity meaning when the Australian elite send their children to Harvard, Yale, Oxford and Cambridge. The same could also be said, and has been, about equity representations by region, institution, discipline and degree. What then, also, for a new national research centre with a focus on student equity and higher education, for its research agenda and positioning in the field? What stance can it take on student equity that will resonate on a national and even international scale? And, given a global field of higher education, what definitions of equity and propositions for policy and practice can it offer? What will work in the pursuit of equity?

Re-searching ethics : towards a more reflexive critical management studies

Fournier and Grey (2000) suggest that those inhabiting the contested terrain of Critical Management Studies (CMS) share a commitment to identifying inequality and subordination in organizations and to the associated possibility of emancipation, however this is conceived. Despite their additional claim that one crucial distinction between critical and non-critical management studies is the ‘philosophical and methodological reflexivity’ of the former (Fournier and Grey 2000: 19), our review indicates limits to this reflexivity in CMS’s empirical practices – indeed, we argue these may even be counter-productive with regard to its political allegiances. To encourage wider discussion of these issues, we provide a tripartite framework of understandings of research ethics drawn from within and outside the management academy, and interrogate the opportunities and limitations of each for enriching CMS research.

A study on small business enterprises in Bangladesh : searching for growth factors and obstacles

Small businesses are the heart of the market-based economy with their business operations in rural and urban areas of developed and developing countries. In Bangladesh, small business enterprises are playing a significant role by contributing to the production and services, employmnet and thereby to GDP. But these are found to face servere competition and different types of constraints. As a result, these have not achieved substantial growth. In view of this, the present study is primarily aimed at identifying factors and obstacles that influence the growth of SBEs. Finally, the paper suggests some policy measures which are expected to excel the growth of SBEs.

Estuary environmental flows assessment methodology : final specification report

This report provides a consistent and systematic approach to the determination of environmental water requirements for estuaries in Victoria.

Victoria’s limited water resources are subject to competing demands. These demands, including town water supplies and irrigation requirements, often deplete the flow entering estuaries and put their environmental values at risk.

The Estuary Environmental Flows Assessment Methodology (EEFAM) is a standard methodology which can be applied in a consistent manner across all Victorian estuaries, according to their priority. It is not anticipated that this method would be used for the Gippsland Lakes or Port Phillip or Western Port Bay.

Hybrid image segmentation using fuzzy clustering algorithms satellite imagery searching and retrieval

Satellite image processing is a complex task that has received considerable attention from many researchers. In this paper, an interactive image query system for satellite imagery searching and retrieval is proposed. Like most image retrieval systems, extraction of image features is the most important step that has a great impact on the retrieval performance. Thus, a new technique that fuses color and texture features for segmentation is introduced. Applicability of the proposed technique is assessed using a database containing multispectral satellite imagery. The experiments demonstrate that the proposed segmentation technique is able to improve quality of the segmentation results as well as the retrieval performance.

Dynamically searching for a domain for protein function prediction

The availability of large amounts of protein-protein interaction (PPI) data makes it feasible to use computational approaches to predict protein functions. The base of existing computational approaches is to exploit the known function information of annotated proteins in the PPI data to predict functions of un-annotated proteins. However, these approaches consider the prediction domain (i.e. the set of proteins from which the functions are predicted) as unchangeable during the prediction procedure. This may lead to valuable information being overwhelmed by the unavoidable noise information in the PPI data when predicting protein functions, and in turn, the prediction results will be distorted. In this paper, we propose a novel method to dynamically predict protein functions from the PPI data. Our method regards the function prediction as a dynamic process of finding a suitable prediction domain, from which representative functions of the domain are selected to predict functions of un-annotated proteins. Our method exploits the topological structural information of a PPI network and the semantic relationship between protein functions to measure the relationship between proteins, dynamically select a suitable prediction domain and predict functions. The evaluation on real PPI datasets demonstrated the effectiveness of our proposed method, and generated better prediction results.

I'm searching for solutions: why are obese individuals turning to the Internet for help and support with 'being fat'?

INTRODUCTION: This study explores what types of information obese individuals search for on the Internet, their motivations for seeking information and how they apply it in their daily lives. METHOD: In-depth telephone interviews with an Australian community sample of 142 individuals with a BMI ≥ 30 were conducted. Theoretical, purposive and strategic samplings were employed. Data were analysed using a constant comparative method. RESULTS: Of the 142 individuals who participated in the study, 111 (78%) searched for information about weight loss or obesity. Of these, about three quarters searched for weight loss solutions. The higher the individual's weight, the more they appeared to search for weight loss solutions. Participants also searched for information about health risks associated with obesity (n = 28), how to prevent poor health outcomes (n = 30) and for peer support forums with other obese individuals (n = 25). Whilst participants visited a range of websites, including government-sponsored sites, community groups and weight loss companies, they overwhelmingly acted upon the advice given on commercial diet websites. However, safe, non-judgemental spaces such as the Fatosphere (online fat acceptance community) provided much needed solidarity and support. CONCLUSIONS: The Internet provides a convenient source of support and information for obese individuals. However, many turn to the same unsuccessful solutions online (e.g. fad dieting) they turn to in the community. Government and community organisations could draw upon some lessons learned in other consumer-driven online spaces (e.g. the Fatosphere) to provide supportive environments for obese individuals that resonate with their health and social experiences, and address their needs.

Searching Baxter's URDF robot joint and link tree for active serial chains

Teleoperation is integral to society's uptake of modern robotic systems. Given the wide array of readily available robots, ranging from simple mobile platforms and UAVs to advanced humanoid robots such as ASIMO and PR2, teleoperation is required in many different forms. The recent advances in virtual reality systems, interactive input controls and even haptic devices facilitate a wide range of new approaches to teleoperation control. This paper considers a dynamic user interface for improving the operator's ability to teleoperate heterogeneous robotic systems in dynamic and challenging environments. In order to achieve the proposed dynamic user interface the robot(s) comprising the heterogeneous robotic system and their active components need to be categorized. The recent uptake of ROS means that many robots are now represented within the standardized Unified Robot Descriptive Format (URDF), and this paper proposes a method for searching the URDF for active serial chains in individual robot systems. Results demonstrate the ability of the approach to determine active serial chains and associated kinematic information for the Baxter torso robot.
