Balancing environmental impacts and benefits of wastewater reuse

Wastewater reuse is being widely promulgated to help address the global freshwater resource crisis. It can assist in reducing extraction of freshwater from the environment, and reuse of wastewater lessens the need for environmental discharge, which is clearly beneficial to receiving waters. But the practice itself also has the potential to be detrimental to natural and human environments: soil structure can become degraded, aquifers may be polluted, and human health may be threatened. The challenge facing natural resource managers is to identify the potential benefits and risks, and to achieve an appropriate balance. This paper describes environmental benefits and threats concomitant with the reuse of wastewater. We frequently draw upon examples from China and Australia-two countries that face particularly daunting water resource
challenges-but the principles can be.extended far beyond these geographical bounds and are applicable to
many parts of the world.

PKI - advantages and obstacles

Electronic communications have become the most important kind of communications in business. However, trust, privacy and security have become the great challenges for business and governments around the globe. The Public Key Infrastructure (PKI) model tries to solve these issues and make the Internet more secure. This paper explains the main purposes of PKI and addresses some of the major issues and obstacles that face PKI technology today.

Emotion, reason and tradition : essays on the social, poltical and economic thought of Michael Polanyi

This collection of essays demonstrates the continuing importance of the work of Michael Polanyi for the understanding, not only of the great events of the 20th century, but also of the problems that face us in the 21st century. Polanyi moved liberalism away from a negative, sceptical and rationalist basis towards an acceptance of trust, tradition and faith in transcendent values. His conception of the free society is not one merely of doing as one pleases nor vacuously 'open', but one of individual and communal self-dedication to those values and ideals.These essays, authored by a distinguished international and interdisciplinary panel of invited contributors, examine Polanyi's specific insights in the theory of knowledge, the nature and source of social order and the philosophy of economics and science and draw relevant comparisons between Polanyi and related thinkers such as Popper, Hayek and Mises. This book shows the sources of Polanyi's ideas and his distinctive contribution to philosophy generally, to social and political thought and to economics.

Whose identity? Valuing the culture built heritage in diverse and tensioned societies

The UNESCO declaration on cultural diversity in 2002 has raised more questions than answers. More recent events around the World have highlighted the immediate need for legislative actions to protect cultural built heritage in tensioned societies. This paper discusses the potential global risks that face cultural built Heritage. The paper argues that such risks are not only limited to regions where military operations are taking place but also to nations where questions of identity and cultural diversity are raised. The paper questioned the reasons and the impact of the rise of ethno nationalism on the protection of cultural built heritage. The different discourses of these groups that will lead to destruction of cultural artefacts are also explored. In order to properly legislate means for the protection of vulnerable cultural built heritage in conflict areas, the underline value system should be clarified and the values under threat identified. The paper concludes with a plea to move our understanding and definition of culture from the previous 'old' definition with relation to "people' to a 'new' one which is more relevant to context.

A sustainable practice: rethinking nature in cultural research

I start this paper with a question that is also a provocation: how sustainable is a cultural studies that does not take account of nature? What I propose is that before we speculate on how this field can engage with the  environmental concerns that face us this question must first be asked. For what cultural studies can offer in the face of ecological stress, I will argue, is circumscribed by its own traditions. If the logics or conceptual parameters of the discipline resist an accommodation of the conditions of sustainability then we have little to offer. Yet if this is the case, what is the future of cultural studies given not only the current import of environmental issues but also the challenge that these material circumstances raise to our dominant traditions of research? Through a discussion of the limits of social constructivism and the prevalence of deconstructive critique in cultural studies, this paper thinks through what an alternative practice might be. It looks to the theoretical and practical application of assemblage, or gathering, as a generative tool for cultural research, and speculates that what we need at this time is a double agenda: to make our own discipline sustainable as we mobilize the  particular capacities, methods and knowledges of cultural research in  response to ecological distress.

Indigenous higher education student equity : focusing on what works

The rates of higher education access, participation and completion for Indigenous students are much lower than those for non-Indigenous students in Australia. This paper argues for a research-led focus on what works in terms of Indigenous  student equity in higher education. Undertaking independent evaluation of  existing initiatives and leveraging the experience of hundreds of successful Indigenous graduates, it may be possible to articulate some of the ways in which success has been, and can be, achieved, despite the challenges that face Indigenous students. In other words, it may be possible to articulate some aspects of what works for some Indigenous people in relation to higher education. A focus on articulating strategies that Indigenous individuals and communities might adopt in relation to higher education should be developed alongside the management of systemic problems through a range of means. The “successfocused” approach would provide one of a suite of approaches that may be helpful in addressing Indigenous student equity.

Community's attitudes towards intimate partner homicide

The thesis aimed to explore the Victorian Community's attitudes towards intimate partner homicide committed in the context of jealousy and domestic violence. Results revealed that the immediacy of the accused's actions, the gender of the accused, and the gender of the participant interacted to influence participants' verdict and blame responses. The portfolio explored the complexities and challenges that face mental health professionals in deciding the appropriate weighting of child's wishes in child protection assessments. The four case studies presented were chosen due to the attention that was paid to the child's wishes throughout the assessments.

Valuation and sustainability : are rating tools enough?

The lack of sufficient financial drivers are preventing significant investment in sustainability because stakeholders have only very limited ability to measure the sustainability of the building or understand the impact upon the value. Valuers are unable to indicate or clarify whether sustainability is affecting market value as there is an absence of detailed market evidence, sales data and lease transactions of sustainable building. Leaving both Valuers and other stakeholders uncertain of the value implication as there is no reliable evidence as to whether sustainable buildings are feasible (Lutzkendorf and Lorenz, 2005). One of the key barriers is the confusion evident in the industry particularly the measurement of sustainability in commercial property. Although a range of environmental rating tools exist for buildings globally in commercial property, the synergy between these tools and identification of the relationship between the measurement and market value is inherently blurred due to the unique nature of the compilation of points attributed in the rating tools for sustainability or energy certificates in commercial property. The paper examines the challenges that face the Valuation profession in assessing the impact of sustainability on market value.

Climate change regulation : implications for business executives

Purpose – The purpose of this paper is to provide an overarching conceptual decision model that delineates the major issues and decisions associated with carbon regulations that will allow executives to better understand the potential regulatory schemes and implications that may be imposed in the near future.
Design/methodology/approach – The authors use the extant literature as the foundation to develop a conceptual model of the decisions pertaining to climate change regulation that face business executives today.
Findings – This paper suggests four major categories of issues that must be addressed in any climate change regulatory scheme. These include: “scope” – will carbon emission management systems be global or regional; “who pays” – will the consumer or will the supply chain be responsible for the cost of their emissions; “market or compliance-based mechanisms” – will the CO2 emissions system be market-based or a compliance-based regulatory system; and “criteria” – how can credence of the remedy be established – what is necessary for a business initiative to qualify for as a creditable carbon offset?
Research limitations/implications – This paper offers a framework that categories the fundamental decisions that must be made in any climate change regulation. This framework may be useful in advancing research into any of the four categories of decisions and their implications on commerce and the environment. This paper is designed to be managerially useful and in that way does limit its ability to specifically advance many dimensions of research.
Practical implications – The paper offers executives for a simple model of the decisions that must be made to craft an effective climate change regulatory scheme. In addition, it suggests how these decisions may create exploitable economic opportunities for innovative and proactive firms.
Originality/value – This paper adds value to the debate by clarifying the decisions that must be addressed in any climate change regulation scheme.

Australian national critical infrastructure protection : a case study

Australia has developed sophisticated national security policies and physical security agencies to protect against current and future security threats associated with critical infrastructure protection and cyber warfare protection. This paper will discuss some of the common security risks that face Australia and how their government policies and strategies have been developed and changed over time, for example, the proposed Australian Homeland Security department. This paper will discuss the different steps that Australia has undertaken in relation to developing national policies to deal with critical infrastructure protection.

Being a parent on dialysis : a literature review

Aim
This literature review explored the extant literature to further our understanding of the experience of being a parent on dialysis.
Methods
Keywords used to search the literature were haemodialysis, hemodialysis, chronic kidney disease, end stage renal disease, parent and experience. Databases searched included CINAHL, Medline, Wiley/Blackwell, EBSCOHost, Web of Science, Pubmed, and ProQuest. Years included were 1999 to 2009. Seventeen primary research articles (sixteen qualitative, one mixed methods) met the search criteria with only one on parents undergoing dialysis.
Findings
The experience of the parent on dialysis has rarely been explored in the literature. Related research has indicated important themes including: restricted lives; relationships; adjustment; consequences and future outlook.
Conclusions
More should be known about challenges that face parents who receive dialysis. This review established an urgent need for further research to determine the experiences and needs of this population to provide empirical, person-centred nursing care.

Protection of Australia in the cyber age

Australia has developed sophisticated national security policies and physical security agencies to protect against current and future security threats associated with critical infrastructure protection and cyber warfare protection. In this paper, the authors examine some common security risks that face Australia and how government policies and strategies have been developed and changed over time, for example, the proposed Australian Homeland Security department. This paper discusses the different steps that Australia has undertaken in relation to developing national policies to deal with critical infrastructure protection.

The effect of financial constraints, investment policy, product market competition and corporate governance on the value of cash holdings

This study empirically investigates the value shareholders place on excess cash holdings and how shareholders’ valuation of cash holdings is associated with financial constraints, firm growth, cash-flow uncertainty and product market competition for Australian firms from 1990 to 2007. Our results indicate that the marginal value of cash holdings to shareholders declines with larger cash holdings and higher leverage. However, firms that are more financially constrained, that have higher growth rates and that face greater uncertainty exhibit a higher marginal value of cash holdings. These findings are consistent with the explanation that excess cash holdings are not necessarily detrimental to firm value. Firms with costly external financing and that also save more cash for current operating and future investing needs find that the market values these cash hoarding policies favourably. Finally, there is limited evidence of an association between various corporate governance measures and the value of cash holdings for a shorter sample period.

Using an online simulation to address equity issues for off-campus students

The Middle East Politics Simulation (MEPS) is an online role-play exercise aimed at providing students with an improved level of understanding of the political dimensions of the Middle East, including the complexities of negotiation and decision making that face actors in this turbulent region. An online version of MEPS has been running since 1993, initially from Macquarie University, and since 2008 from Deakin University. This longevity provides a useful longitudinal perspective on utilising a collaborative online workplace to offer enhanced learning outcomes in the study of a political topic. The wholly online nature of the simulation means that students of all study modes and even different institutions can participate and benefit equally, thus negating some of the disadvantages faced by off-campus students in learning and assessment. Additionally, the student experience and depth of learning provided by the simulation constitute an excellent example of using the strengths of an e-learning environment to offer an alternative method of engaging and assessing students, which may be beneficial for accommodating the needs of those with differing learning styles.
