Massaging desire : disadvantaged students\u27 aspirations for higher education.

Australia is in a challenging position. Having ridden the resources boom up and down, it now finds it has fallen back from the OECD pack in terms of the number of young adults (25 to 34 year olds) with higher education qualifications. This, coupled with a change of government, has prompted transformation in the Australian higher education system that will increasingly require research and policy to address students’ aspirations for university. Aspiration has long been considered an important condition for entry to higher education (Anderson, Boven, Fensham & Powell, 1980). However, recent policy reforms, specifically the setting of targets for significant increases in participation, now demand a rethinking of the concept. Across Australian universities, the current attainment rate for bachelor degrees among 25 to 34 year olds is around 32 per cent, while over the past twenty years the enrolment rate of students from low socioeconomic status (SES) backgrounds has stagnated at around 15 per cent (Commonwealth of Australia, 2009). In response to the Bradley Review of Australian Higher Education in 2008, the Australian Government has set ‘20/40 targets’ in a bid to increase low SES enrolment to 20 per cent by 2020, and to increase to 40 per cent by 2025 the number of 25 to 34 year olds holding bachelor degrees. This will require that around 220,000 additional students attain bachelor degrees by 2025. Given current levels of unmet demand for university entry, this overall increase in participation, and the proportional increase of low SES students in particular, will only be achievable by engaging with populations of potential students who do not currently seek university places

Wave intensity analysis: A novel non-invasive method for determining arterial wave transmission

Wave intensity analysis is a novel technique for assessing wavelet transmission in the cardiovascular system. Using this tool, we have developed non-invasive techniques to study wave transmission in both central & peripheral arteries in man. The aim of this study was to determine the reproducibility of various haemodynamic measures in the carotid, brachial and radial arteries. 12 treated hypertensive men underwent applanation tonometry and pulsed Doppler ultrasound studies of the carotid, brachial and radial arteries on 2 occasions. Coefficients of variation for the local wave speed, cardiac compression wave intensity and main reflected wave intensity ranged between 3.7-6.6%, 8.2-11.4% and 12.5-19.6% respectively. We conclude that non-invasive methods used for wave intensity analysis are reproducible & provide additional information regarding the complex phenomenon of arterial wave transmission in man

Pro/con ethics debate: Should mechanical ventilation be continued to allow for progression to brain death so that organs can be donated?

Organ transplants continue to redefine medical frontiers. Unfortunately, current demand for organs far surpasses availability, waiting lists are long and many people die before the organ they desperately need becomes available. One proposed way to increase organ availability is to admit patients to the ICU with severe neurological injuries, for a trial of therapy. If the injury is irretrievable, discussions would then focus on extending ventilation for potential brain death/organ donation if a prior wish to donate is known or if the substitute decision maker consents. The following debate discusses the ethical dilemmas of waiting for brain death

When the snowball fails to roll and the use of ‘horizontal’ networking in qualitative social research

Snowball sampling is frequently advocated and employed by qualitative social researchers. Under certain circumstances, however, it is prone to faltering and even failure. Drawing on two research projects where the snowball failed to roll, the paper identifies reasons for this stasis. It goes on to argue that there are alternative forms of networking that can be developed by the qualitative social researcher in lieu of snowballing. Specifically, when research momentum fails to build, rather than drilling down vertically through social networks, we argue that the researcher can move horizontally across social networks and cast the sampling and recruitment net wide and shallow rather than deep. This change in emphasis can, we argue, make the difference between a project failing and a project succeeding, and points to the importance of a variegated understanding of the social networks on which our social research depends

Appreciating aspirations in Australian higher education

Aspiration for higher education (HE) is no longer a matter solely for students and their families. With OECD nations seeking to position themselves more competitively in the global knowledge economy, the need for more knowledge workers has led to plans to expand their HE systems to near universal levels. In Australia, this has required the government and institutions to enlist students who traditionally have not seen university as contributing to their imagined and desired futures. However, this paper suggests that failing to appreciate the aspirations of different groups, understood as a collective cultural capacity, casts doubt over the ability of institutions to deliver increased numbers of knowledge workers. Moreover, inciting subscription to the current norms of HE is a weak form of social inclusion. Stronger forms of equity strategy are possible when HE is repositioned as a resource for different groups and communities to access in the pursuit of their aspirations.<br /

PassViz: A Visualisation System for Analysing Leaked Passwords

Passwords remain the most widely used form of user authentication, despite advancements in other methods. However, their limitations, such as susceptibility to attacks, especially weak passwords defined by human users, are well-documented. The existence of weak human-defined passwords has led to repeated password leaks from websites, many of which are of large scale. While such password leaks are unfortunate security incidents, they provide security researchers and practitioners with good opportunities to learn valuable insights from such leaked passwords, in order to identify ways to improve password policies and other security controls on passwords. Researchers have proposed different data visualisation techniques to help analyse leaked passwords. However, many approaches rely solely on frequency analysis, with limited exploration of distance-based graphs. This paper reports PassViz, a novel method that combines the edit distance with the t-SNE (t-distributed stochastic neighbour embedding) dimensionality reduction algorithm for visualising and analysing leaked passwords in a 2-D space. We implemented PassViz as an easy-to-use command-line tool for visualising large-scale password databases, and also as a graphical user interface (GUI) to support interactive visual analytics of small password databases. Using the "000webhost" leaked database as an example, we show how PassViz can be used to visually analyse different aspects of leaked passwords and to facilitate the discovery of previously unknown password patterns. Overall, our approach empowers researchers and practitioners to gain valuable insights and improve password security through effective data visualisation and analysis
