Making water public

The recent 11 years of conservative government rule in Australia was marked by what some commentators refer to as a 'hardening of hearts' and a notable decline in the public realm. At the same time, climate change and drought made an increasing impact on Australian environments and society. This paper responds to the overwhelming tendency, which it aligns with a retreat from the concept of public-ness, to instrumentalise efforts to remediate environmental decline. Focusing in particular on water - or the lack of it - in Australia today, the paper draws on innovations in cultural theory and research practice to retum the question of public-ness to centre stage. This involves a reorientation of what it might mean to 'make water public'  that is not reliant on the sole agency of humans.

Dominant drivers of seedling establishment in a fire-dependent obligate seeder: climate or fire regimes?

Climate change is causing fire regime shifts in ecosystems worldwide. Plant species with regeneration strategies strongly linked to a fire regime, such as obligate seeders, may be particularly threatened by these changes. It is unclear whether changes in fire regimes or the direct effects of climate change will be the dominant threats to obligate seeders in future. We investigated the relative importance of fire-related variables (fire return interval andfire severity) and environmental factors (climate and topography) on seedling establishment in the world's tallest angiosperm, an obligate seeder, Eucalyptus regnans. Throughout its range, this species dominates the wet montane forests of south-eastern Australia and plays a keystone role in forest structure. Following major wildfires, we investigated seedling establishment in E. regnanswithin 1 year of fire as this is a critical stage in the regeneration niche of obligate seeders. Seedling presence and abundance were strongly related to the occurrence of fire but not to variation in fire severity (moderate vs. high severity). Seedling abundance increased with increasing fire return interval (range 26-300 years). First-year seedling establishment was also strongly associated with low temperatures and with high elevations, high precipitation and persistent soil water availability. Our results show that both climate and fire regimes are strong drivers of E. regnans seedling establishment. The predicted warming and drying of the climate might reduce the regeneration potential for some obligate seeders in future and these threats are likely to be compounded by changes in fire regimes, particularly increases in fire frequency.

The world to come: stories

In 1738, English preacher, Isaac Watts wrote ‘The world to come’, a Christian tract about departed souls, death, and the glory or terror of the resurrection. Almost 300 years later the world to come still fascinates readers. It’s not only climate change, it’s the climate of everything: from technological ‘advances’ that threaten to create an immortal humanity; to an endless ‘war on terror,’ which means that, though we may never know war, nor will we ever truly know peace; to a thousand visions of post-Apocalyptic life in the media. The world to come is everywhere; it is with us now… In this anthology, twenty-one writers respond to the world to come – the one just around the corner, the hereafter and the everywhen.

Tax incentives for foreign direct investment part I : Recent trends and countertrends

According to the conventional wisdom, tax incentives for investment - in particular for foreign direct investment (FDI) - are not recommended. That is the view held almost universally by theorists and by the international bodies that advise on tax matters.' Tax incentives are bad in theory and bad in practice. They are bad in theory principally because they cause distortions: investment decisions are made that would not have been made without the inducement of special tax concessions. They are bad in practice, being both ineffective and inefficient. They are ineffective in that tax considerations are only rarely a major determinant in FDI decisions; they are inefficient because their cost, in terms of tax revenue foregone, often far exceeds any benefits they may produce. Other criticisms are also frequently levelled against tax incentives for FDI - they are inequitable (since they benefit some investors but not others), they are difficult to administer and open to abuse, and they lack transparency. Thus, it is not surprising that ''the standard advice given by institutions like the World Bank and the lMF to developing countries is to refrain from offering tax incentives to foreign investors".2 The purpose of this article is not to question that advice or to challenge the conventional wisdom - except in one respect. Recent evidence does suggest that tax considerations are an increasingly important factor in investment decisions and that special tax incentives have become substantially more effective as instruments for attracting FDI than they were 10 or 20 years ago.3 The first part of this article, published here, examines some of that evidence, reviews some recent trends in national policies towards FDI, attempts to suggest why investment incentives have become more important and more effective, and looks at the pressures that are exerted on governments, especially in developing countries, to compete for FDI by offering special incentives. The second part of the article, to be published in the Bulletin next month, assumes that many countries will continue to offer tax incentives to investors regardless of the best advice, and considers how incentives might be designed in order to increase their effectiveness and efficiency.

Section 46:where we have been and where we are going: a review of the recent debate

Two recent reviews of Part IV of the Trade Practices Act (Commonwealth) (1974) have looked specifically at the operation of Section 46 of this Act and have come to very different conclusions concerning its efficacy. The Dawson review (2003) argued that no change to S 46 was required as the courts were providing sufficient guidance in the application of the legislation in this respect. The Senate Committee review (2004) came to different conclusions arguing that the Act needed clarification in regard to certain sections. These reports highlight the controversy that has surrounded this section of the Trade Practices Act for the past thirty years. The aim of this paper is to consider these reviews and evaluate the extent to which the High Court has been able to provide guidance in the application of legislation that prohibits the misuse of market power.

Short-run performance of recent Australian on-market share buy-back announcements

Share buy-backs (or share repurchases) have become increasingly popular among Australian companies during the recent times. One of the aims of share buy-back is to increase the shareholders' wealth by increasing the market price of company shares. While there are several ways of buying backs shares, on-market buy-backs is the most popular method of share repurchase in Australia. Australian listed companies have announced more than two hundred on-market share buy-backs over the past three years. The aim of this paper is to examine the short-run market performance of these recent on-market buy-back announcements.

Short-term effect of on-market buy-back announcements on the share price is an issue, which is theoretically interesting and practically important. Buy-back announcements are believed to convey a signal to the market (i.e., signalling effect). If the market considers this signal positively, the short-run price of the shares would increase. If the signal were considered negatively, the short-run price of shares would decrease. If there is no signalling content or the signal is neutral the price would remain the same. In this study, signalling effect of share buy-back announcements is empirically examined using most recent Australian data. The total population of on-market buy-back announcements that have been lodged with Australian Stock Exchange by Australian listed companies during the period from 1 January 2000 to 10 March 2003 are included in this study. The abnormal market return over the short-run (announcement day and 10 trading days centred on the announcement date) is examined using the All Ordinaries Accumulation Index as the reference portfolio. The daily abnormal returns (AR) and cumulative abnormal returns (CAR) during the event period are computed. The results indicate that the Australian market generally positively reacts to on-market buy-back announcements.

Mind the gap 2014 : research to inform the next five years of library development

Libraries have a long history of gathering evidence of performance. The results of regular client satisfaction surveys directly inform the continuous improvement of library and information services. Staff and student input is critical for improving library physical and virtual spaces, facilities and resources, and also to learn how the university community may approach information discovery into the future.

At Deakin University Library we are investigating, developing and integrating Web 2.0 applications into our service delivery. At the same time, designs for next generation physical learning spaces are being developed and implemented. These will extend the opportunities for students to contribute to a connected network of learners and teachers, to develop social networks, and to enrich experience of university life. Both the online and spaces strategies support the University’s distinctive advantage in flexible education.

But what of the future? How can the Library ensure that its support of research, teaching and learning aligns with changes in the behaviour and preferences of the university community in the next five years? This paper reviews Deakin University Library’s recent achievements, exposes an important gap and previews its plans to ensure its reliable support to the university community continues.

New world orders and the dystopian turn : transforming visions of territoriality and belonging in recent Australian children's fiction

Through the 1990s and into the new millennium, Australian children's literature responded to a conservative turn epitomised by the Howard government and to new world order imperatives of democracy, the market economy, globalisation, and the IT revolution. These responses are evidenced in the ways that children's fiction speaks to the problematics of representation and cultural identity and to possible outcomes of devastating historical and recent catastrophes. Consequently, Australian children's fiction in recent years has been marked by a dystopian turn. Through an examination of a selection of Australian children's fiction published between 1995 and 2003, this paper interrogates the ways in which hope and warning are reworked in narratives that address notions of memory and forgetting, place and belonging. We argue that these tales serve cautionary purposes, opening the way for social critique, and that they incorporate utopian traces of a transformed vision for a future Australia. The focus texts for this discussion are: Secrets of Walden Rising (Allan Baillie, 1996), Red Heart (Victor Kelleher, 2001), Deucalian (Brian Caswell, 1995), and Boys of Blood and BOlle (David Metzenthen, 2003).

MOSAIC (MOthers' Advocates In the Community): protocol and sample description of a cluster randomised trial of mentor mother support to reduce intimate partner violence among pregnant or recent mothers

Background : Intimate partner violence (IPV) is prevalent globally, experienced by a significant minority of women in the early childbearing years and is harmful to the mental and physical health of women and children. There are very few studies with rigorous designs which have tested the effectiveness of IPV interventions to improve the health and wellbeing of abused women. Evidence for the separate benefit to victims of social support, advocacy and non-professional mentoring suggested that a combined model may reduce the levels of violence, the associated mental health damage and may increase a woman's health, safety and connection with her children. This paper describes the development, design and implementation of a trial of mentor mother support set in primary care, including baseline characteristics of participating women.

Methods/Design : MOSAIC (MOtherS' Advocates In the Community) was a cluster randomised trial embedded in general practice and maternal and child health (MCH) nursing services in disadvantaged suburbs of Melbourne, Australia. Women who were pregnant or with infants, identified as abused or symptomatic of abuse, were referred by IPV-trained GPs and MCH nurses from 24 general practices and eight nurse teams from January 2006 to December 2007. Women in the intervention arm received up to 12 months support from trained and supported non-professional mentor mothers. Vietnamese health professionals also referred Vietnamese women to bilingual mentors in a sub-study. Baseline and follow-up surveys at 12 months measured IPV (CAS), depression (EPDS), general health (SF-36), social support (MOS-SF) and attachment to children (PSI-SF). Significant development and piloting occurred prior to trial commencement. Implementation interviews with MCH nurses, GPs and mentors assisted further refinement of the intervention. In-depth interviews with participants and mentors, and follow-up surveys of MCH nurses and GPs at trial conclusion will shed further light on MOSAIC's impact.

Discussion : Despite significant challenges, MOSAIC will make an important contribution to the need for evidence of effective partner violence interventions, the role of non-professional mentors in partner violence support services and the need for more evaluation of effective health professional training and support in caring for abused women and children among their populations.

Generic medicines in Australia : business dynamics and recent policy reform

This article describes the role of generics in the Australian prescription drug market and patterns of business activity in this dynamic market segment. The Pharmaceutical Benefits Scheme (PBS) is the central mechanism for the supply of prescription medicines. PBS prices are arrived at through cost-effectiveness analyses comparing new products against already available products and therapies. In this system, prices do not operate effectively as incentives for consumers or prescribers to choose generics, and their market share was historically marginal. In recent years, generics suppliers achieved a growing market share through discounts (trading terms) to pharmacists. It is estimated that around 30% of PBS scripts, representing around 15% of PBS sales by value, are now filled with generics. Complex changes to the PBS were introduced in 2007, to be phased in over the period to 2012, aimed at increasing the scope for cost benefits to the government, and to lesser extent consumers, from the expanding availability of generic medicines.

Organic ionic plastic crystals : recent advances

Investigations into the synthesis and utilisation of organic ionic plastic crystals have made significant progress in recent years, driven by a continued need for high conductivity solid state electrolytes for a range of electrochemical devices. There are a number of different aspects to research in this area; fundamental studies, utilising a wide range of analytical techniques, of both pure and doped plastic crystals, and the development of plastic crystal-based materials as electrolytes in, for example, lithium ion batteries. Progress in these areas is highlighted and the development of new organic ionic plastic crystals, including a new class of proton conductors, is discussed.

Recent advances in anti-survivin treatments for cancer

Apoptosis occurs via extrinsic or intrinsic signalling each triggered and regulated by many different molecular pathways. In recent years, the selective induction of apoptosis through survivin in tumour cells has been increasingly recognized as a promising approach for cancer therapy. Survivin has multiple functions including cytoprotection, inhibition of cell death, and cell-cycle regulation, especially at the mitotic process stage, all of which favour cancer survival. Many studies on clinical specimens have shown that survivin over expression is invariably up regulated in human cancers, associated with resistance to chemotherapy or radiation therapy, and linked to poor prognosis, suggesting that cancer cells survive with survivin. On the basis of these findings, survivin has been proposed as an attractive target for new anticancer interventions. Survivin inhibitors recently entered clinical trials. Recent studies suggest a possible role for survivin in regulating the function of normal adult cells. However, the expression and function of survivin in normal tissues are still not well characterized and understood. Still better understandings of survivin's role in tumour versus normal cells are needed for designing the strategies to selectively disrupt survivin in cancers. In the present review, we summarise the importance of recent survivin-targeted cancer therapy for future clinical application.

Diabetes risk reduction behaviours of rural postpartum women with a recent history of gestational diabetes

Introduction: For most women, gestational diabetes is temporary; however, an episode of gestational diabetes mellitus (GDM) confers an approximately seven-fold increased risk of developing type 2 diabetes mellitus. Objective: To examine readiness to adopt diabetes risk reduction behaviours and the prevalence of these behaviours among rural women with GDM during their last pregnancy.
Methods: The study design was a self-administered mailed questionnaire seeking information about demographics, stage of change, physical activity level and dietary fat intake. Setting: Regional outpatient context. Participants: Women with a single episode of GDM between 1 July 2001 and 31 December 2005 (n = 210). Main outcome measures: Stage of change for physical activity, weight loss and reducing dietary fat behaviour; meeting activity targets, body mass index (BMI) and dietary fat score.
Results: Eighty-four women returned completed questionnaires (40% response rate). Of the 77 women eligible (mean age 35 ± 3.8 years), 58% met recommended activity targets. Sixty-three percent of women were overweight or obese: mean BMI 29.6 kg/m2 (± 7.30). Women reported a high level of preparedness to engage in physical activity, weight loss and reduction of fat intake. Thirty-nine percent of women had not had any postpartum follow-up glucose screening. Women who remembered receiving diabetes prevention information were significantly more likely to meet physical activity targets (p<0.05).
Conclusions: Readiness to engage in behaviour change was high among this group of rural women for all three diabetes risk reduction behaviours measured. However, despite a high proportion of women meeting activity targets and reducing fat intake, the majority of women remained overweight or obese. Postpartum follow-up glucose testing needs to be improved and the impact of diabetes prevention information provided during pregnancy warrants further study.

Rethinking attachment : fostering positive relationships between infants, toddlers and their primary caregivers

This article provides a synthesis of current theory and research in relation to attachment between infants/toddlers and their caregivers. Worldwide statistics show that there are a significant number of women working in the global labour market. In Australia, recent research also found that over 300,000 children aged 0-5 years are currently attending long day child care, and a child can spend up to 12,500 hours in child care before starting school (based on attendance of 50 hours per week for five years). In order to understand the importance of developing secure relationships that build on the first transition from home to child-care centre, semi-structured interviews were conducted to collect views from parents and child-care staff. Results showed that most participants in the sample were in favour of using a primary caregiver approach. Implications for the implementation of this approach will be discussed.

Self-assembled monolayers into the 21st century : recent advances and applications

The modification of an interface on a molecular level with more than one molecular ‘building block' is essentially an example of the ‘bottom–up' fabrication principle of nanotechnology. The fabrication of such integrated molecular systems in electrochemistry has seen rapid progress in recent years via the development of sensing interfaces fabricated using self-assembled monolayers (SAMs). This review outlines recent advances and applications of self-assembled monolayers for modifying electrodes with an emphasis on the development of integrated molecular systems. First, some basic issues regarding fabricating integrated molecular systems, such as the role of the surface topography of the electrode and patterning surfaces, are discussed. Subsequently an overview of recent developments in pH, inorganic and bio sensing involving the use of SAMs is given. Finally emerging trends in using molecular building blocks in the fabrication of integrated molecular systems, such as nanotubes, dendrimers and nanoparticles, are reviewed.
