Urban consolidation : reality or fantasy

Urban consolidation has been a policy objective of many local and state governments in Australia for the past decade. Densification of city centres and other identified activity centres is a sensible solution to a plethora of policy objectives including: growth management, housing affordability, housing choice and infrastructure utilisation etc whilst preserving the fabric of existing neighbourhoods. However despite the plethora of supportive policies and ripe redevelopment sites, urban sprawl continues to permeate city fringes and affordable urban densification in the post GFC environment slips into the “too hard” basket. This article discusses current issues facing the development industry, highlighting factors contributing to the disequilibrium between demand and supply in the medium to high density residential markets.

Secretome and degradome profiling shows that Kallikrein-related peptidases 4, 5, 6, and 7 induce TGFβ-1 signaling in ovarian cancer cells

Kallikrein-related peptidases, in particular KLK4, 5, 6 and 7 (4-7), often have elevated expression levels in ovarian cancer. In OV-MZ-6 ovarian cancer cells, combined expression of KLK4-7 reduces cell adhesion and increases cell invasion and resistance to paclitaxel. The present work investigates how KLK4-7 shape the secreted proteome ("secretome") and proteolytic profile ("degradome") of ovarian cancer cells. The secretome comparison consistently identified >900 proteins in three replicate analyses. Expression of KLK4-7 predominantly affected the abundance of proteins involved in cell-cell communication. Among others, this includes increased levels of transforming growth factor β-1 (TGFβ-1). KLK4-7 co-transfected OV-MZ-6 cells share prominent features of elevated TGFβ-1 signaling, including increased abundance of neural cell adhesion molecule L1 (L1CAM). Augmented levels of TGFβ-1 and L1CAM upon expression of KLK4-7 were corroborated in vivo by an ovarian cancer xenograft model. The degradomic analysis showed that KLK4-7 expression mostly affected cleavage sites C-terminal to arginine, corresponding to the preference of kallikreins 4, 5 and 6. Putative kallikrein substrates include chemokines, such as growth differentiation factor 15 (GDF 15) and macrophage migration inhibitory factor (MIF). Proteolytic maturation of TGFβ-1 was also elevated. KLK4-7 have a pronounced, yet non-degrading impact on the secreted proteome, with a strong association between these proteases and TGFβ-1 signaling in tumor biology. © 2013 Federation of European Biochemical Societies.

Raising awareness of Australian Aboriginal peoples reality : Embedding Aboriginal knowledge in social work education through the use of field experiences

Effective social work practice with Aboriginal peoples and communities requires knowledge of operational communication skills and practice methods. In addition, there is also a need for practitioners to be aware of the history surrounding white engagement with Aboriginal communities and their cultures. Indeed, the Australian Association of Social Workers (AASW) acknowledges the importance of social workers practising cultural safety. Engendering knowledge of cultural safety for social work students is the opportunity to listen and talk with Aboriginal people who have experienced the destructive impacts of colonisation and the subsequent disruption to family and community. This article discusses the use of field experiences within a Masters of Social Work (Qualifying) Program (MSW) as an educational method aimed at increasing student awareness of contemporary Aboriginal issues and how to practice effectively and within a culturally safe manner.

A pilot randomised trial of Medilixir cream shows some promising results, but control treatment may have been inappropriate

Aim To test the efficacy of Medilixir [cream] against the standard treatment of aqueous cream in the provision of relief from the symptoms of postburn itch. Design RCT with two parallel arms. Setting Professor Stuart Pegg Adult Burns Centre, Royal Brisbane and Women's Hospital, Brisbane, Australia. Participants Fifty-two patients aged between 18 and 80 years, admitted directly to the burns centre between 10 March and 22 July 2008, were able to provide informed consent, and had shown no allergic reaction to a patch test with the study medication, were randomised. Patients admitted from intensive care or high dependency were excluded. Main results Effect estimates and confidence intervals were not reported for any of the outcomes; only group means/proportions and P-values from hypothesis testing were provided. More patients in the intervention group reported itch reduction compared to comparison treatment (91 vs. 82%, P=0.001). Itch recurrence after cream application occurred later in the intervention group compared to the control group (P<0.001). Use of antipruritic medication was significantly greater in the control group (P=0.023). There was no difference in sleep disturbance between groups (not quantified). On average, Medilixir took longer to apply than aqueous cream (157s for Medilixir vs. 139s for aqueous cream; mean difference 17s), but authors noted that the groups did not differ significantly (CI for mean difference and P-values were not reported).

Paper-based mixed reality sketch augmentation as a conceptual design support tool

This undergraduate student paper explores usage of mixed reality techniques as support tools for conceptual design. A proof-of-concept was developed to illustrate this principle. Using this as an example, a small group of designers was interviewed to determine their views on the use of this technology. These interviews are the main contribution of this paper. Several interesting applications were determined, suggesting possible usage in a wide range of domains. Paper-based sketching, mixed reality and sketch augmentation techniques complement each other, and the combination results in a highly intuitive interface.

Music festivals are in trouble but the shows must go on

It’s no secret that the music festival scene in Australia has recently hit some troubled waters. Harvest festival has been cancelled this year, unpaid performers are still chasing the organisers of the failed Peats Ridge festival and Britpop superstars Blur recently pulled out of the Big Day Out, saying festival organisers “have let us down”. What factors are driving this upheaval, and why do some festivals survive where others fail?

Online fine line : using social media to predict the Big Brother eviction

Reality television, alongside shows such as Q&A – which may be Reality TV in all but name – frequently drives social media conversations about the Australian television industry. Big Brother, currently screening on Channel 9, is consistently among the shows with the highest levels of chatter in that regard. The precise Facebook data is hard to quantify but the Official Big Brother page boasts 805,400 likes and more than 59,000 comments since the start of the series, suggesting it has established a firm presence on that platform too...

From true story to Morning Glory : fantasy and reality in journalism movies

Many movies have been made about journalists, including some of cinema’s all-time classics. Fewer have been made about the process of journalism, however, and fewer still have captured that process in a way which reflects the reality of a hyperactive, stressedout trade that at its best confronts power and risks everything to expose its abuse. Those deemed to come close to that gritty realism regularly feature in those polls of the films journalists themselves think are the best representations of their oft-maligned profession. These are the films in which journalists like to think they see themselves. They are part of the professional mythology of journalistic practice.

Developing health literacy through school based health education : can reality match rhetoric

Recently in Australia, the National Health and Hospitals Reform Commission (2009) and National Preventative Health Taskforce (2009) recommended that one way to strengthen consumer engagement within a health system is to ensure health literacy comprise a core element of the National Curriculum for primary and secondary schooling. However, whilst nationally and internationally schools are mandated to teach health education, there is considerable disjuncture between societies' broad expectations and schools' capacities to deliver programs that promote healthy Jiving (Marks, 2010; Basch, 2010). Given the centrality of literacy education in contemporary schooling (Snyder, 2008), 'health literacy' has been identified as a construct that offers the potential to close this perceived gap (McCuaig, Coore & Hay, 2012; Kickbusch, 2001). To date, there has been limited research asto what a health literacy focused, school based health education curriculum could look like.

Understanding expectations with multiple controllers in an augmented reality videogame

Player experiences and expectations are connected. The presumptions players have about how they control their gameplay interactions may shape the way they play and perceive videogames. A successfully engaging player experience might rest on the way controllers meet players' expectations. We studied player interaction with novel controllers on the Sony PlayStation Wonderbook, an augmented reality (AR) gaming system. Our goal was to understand player expectations regarding game controllers in AR game design. Based on this preliminary study, we propose several interaction guidelines for hybrid input from both augmented reality and physical game controllers

Love hurts: The costly reality of online romance fraud

Online dating and romance scams continue to lure in Australians with figures this week showing people have lost more than A$23 million this year alone, with average individual losses at A$21,000 – three times higher than other types of fraud. The Australian Competition and Consumer Commission (ACCC) set up the Scam Disruption Project in August to help target those it believes have been caught in such scams. Over three months it sent 1,500 letters to potential victims in New South Wales and the Australian Capital Territory. The figures released this week show that 50 people have been scammed, losing a total A$1.7 million – that’s an average of A$34,000 per victim. Almost three quarters of the scams were dating and romance related, which saw it evolve into the number one category of fraud victimisation. Romance scams continue to pose a problem – despite the efforts of the police and ACCC – so why is it that people continue to fall for them?

Improving access to housing for low-income communities in Dhaka: From rhetoric to reality in community participation

The research explores how community participation can address affordable housing problems of the poor in Dhaka. The research, based on extensive interviews, community focus groups and household surveys in different Dhaka slums, identifies the limiting factors to promote community participation in affordable housing creation. In Dhaka housing options for poor are currently limited to affordable shelters in informal settlements. Public housing programs have failed to reach the poor and meet affordability levels due to a number of factors including lack of beneficiary participation. Beneficiary participation, though widely recognized for success in housing initiatives, often deteriorates in process of implementation into mere involvement, not reflecting community needs and aspirations and thus failing to meet its core objectives. This research identified the most significant impediments as well as opportunities to advance participation in their own housing provisions in Dhaka city.

Communication and essentialism: Grounding the shared reality of a social category

Essentialism is an ontological belief that there exists an underlying essence to a category. This article advances and tests in three studies the hypothesis that communication about a social category, and expected or actual mutual validation, promotes essentialism about a social category. In Study 1, people who wrote communications about a social category to their ingroup audiences essentialized it more strongly than those who simply memorized about it. In Study 2, communicators whose messages about a novel social category were more elaborately discussed with a confederate showed a stronger tendency to essentialize it. In Study 3, communicators who elaborately talked about a social category with a naive conversant also essentialized the social category. A meta-analysis of the results supported the hypothesis that communication promotes essentialism. Although essentialism has been discussed primarily in perceptual and cognitive domains, the role of social processes as its antecedent deserves greater attention.

Professional spaces for pre-service teachers: sites of reality, imagination and resistance

Questions about the practicum within teacher education tend to focus on the amount of time allocated to it in programs. In this research, we were interested in the quality of the experience rather than assuming ‘more is better’. To understand what is going on and where, this study focussed on the school and specially the departmental office of room as a site for workplace learning. Using qualitative methods we constructed narratives from the data provided by a cohort of four-year bachelor degree pre-service teachers during and following their final major (10 week)practicum experience. Using theories of spatiality to make sense of the data, we found that the narratives revealed stories of spaces where compliance, disappointment were the key features of the practicum, and where resistance through absence (from the departmental office) was an important strategy to manage the experience. This research challenges the ‘more is better’ argument.

Indigenous Australia is deadly – and Leah Purcell shows it (Documentary review)

Urban skyline, as seen from inside a medium-density apartment block, opens Australian director Leah Purcell’s Who We Are: Brave New Clan (2014), which was broadcast on Foxtel’s Bio Channel last night. The one-off documentary – which deserves another run – follows the lives of six Indigenous Australians (not connected in real life but our “clan” for the sake of the documentary). Does it work? Oh yes...
