Better use of rhetorical theory in public relations

Some of the most important reflections on rhetorical theory associated with public relations appear in: L’Etang (1996); Toth (1999); and various Robert Heath contributions. This paper will reflect on the importance of that work by briefly scouring the origin of rhetoric among the ancient founders of persuasive communication: the pre-Socratic sophists. The paper will then relate the approaches of the above theorists, as well as Kevin Moloney and James Grunig, to the original meaning of sophistry. The last part of the paper will discuss the confluence of rhetorical and semiotic approaches. The rhetoricsemiotics link has been present since the semiotics of St Augustine of Hippo (354-430 CE). Augustine was a professor of rhetoric in his earlier career. The last part of the paper summarises how rhetorical theory, Peircean semiotics and post modern approaches can avoid accusations of relativism and infinite semiosis when they are fitted into a theory of public relations.

Allocating risks in public-private partnership projects using a transaction cost economics approach - a case study

Public-private partnership (PPP) projects are often characterised by increased complexity and uncertainty due to their idiosyncrasy in the management and delivery processes such as long-term lifecycle, incomplete contracting, and the multitude of stakeholders. An appropriate risk allocation is particularly crucial to achieving project success. This paper focuses on the risk allocation in PPP projects and argues that the transaction cost economics (TCE) theory can integrate the economics part, which is currently missing, into the risk management research. A TCE-based approach is proposed as a logical framework for allocating risks between public and private sectors in PPP projects. A case study of the Southern Cross Station redevelopment project in Australia is presented to illustrate the approach. The allocation of important risks is put under scrutiny. Lessons learnt are discussed and alternative management approaches drawing on TCE theory are proposed.

Neurofuzzy decision support system for efficient risk allocation in public-private partnership infrastructure projects

The performance of public-private partnership (PPP) infrastructure projects is largely contingent on whether the adopted risk allocation (RA) strategy is efficient. Theoretical frameworks drawing on the transaction cost economics and the resource-based view of organizational capability are able to explain the underlying mechanism but unable to accurately forecast efficient RA strategies. In this paper, a neurofuzzy decision support system (NFDSS) was developed to assist in the RA decision-making process in PPP projects. By combining fuzzy and neural network techniques, a synthesized fuzzy inference system was established and taken as the core component of the NFDSS. Evaluation results show that the NFDSS can forecast efficient RA strategies for PPP infrastructure projects at a highly accurate and effective level. A real PPP infrastructure project is used to demonstrate the NFDSS and its practical significance.

Working together : collaboration between midwives and doctors in public hospitals

While collaborative, multidisciplinary teamwork is widely espoused as the goal of contemporary hospitals, it is hard to achieve. In maternity care especially, professional rivalries and deep-seated philosophical differences over childbirth generate significant tensions. This article draws on qualitative research in several Victorian public maternity units to consider the challenges to inter-professional collaboration. It reports what doctors and midwives looked for in colleagues they liked to work with — the attributes of a “good doctor” or a “good midwife”. Although their ideals did not entirely match, both groups respected skill and hard work and sought mutual trust, respect and accountability. Yet effective working together is limited both by tensions over role boundaries and power and by incivility that is intensified by increasing workloads and a fragmented labour force. The skills and qualities that form the basis of “professional courtesy” need to be recognised as Aust Health Rev 2009: 33(2): 315–324 essential to good collaborative practice.

Authentication in public key encryption schemes

This thesis analyses authentication in public key encryption and makes contributions in two areas. Firstly, Compressed Nested PKI is proposed which improves the certificate validation process. Then an implicitly certified encryption scheme, Authenticated Public Key Encryption, which makes keys easier to manage, is introduced.

The lived experience of registered nurses caring for adolescent females diagnosed with anorexia nervosa on adolescent wards in public hospitals in Victoria

Explores in depth the experiences of registered nurses caring for female patients diagnosed with anorexia nervosa on adolescent wards in public hospitals in Victoria. The philosophy of Husserl and the procedural steps of analysis developed by Paul Colaizzi were the basis for investigating and extracting the essence of the lived experiences of participants.

Risk allocation in public-private partnership projects

Both the increasing private participation in public projects and the critical importance of appropriate risk allocation to the success of public-private partnership (PPP) projects justify specific research on the risk allocation practice in PPP projects, particularly whether the practice is value-for-money driven. In this paper, the risk allocation in construction projects is examined firstly. The risks associated with PPP projects and the concept of optimal risk allocation are then reviewed. More importantly, the risk allocation practice in PPP projects is examined, particularly in the Australian context. Important issues, such as the current practice, the governments' accountability, and achieving efficient allocation, are discussed. The discussion presented in this paper is expected to justify and elicit further research on how to achieve efficient risk allocation in PPP projects

Alternative water strategies in public domains : innovative strategies in progress along North Terrace, Adelaide

Water sensitive design on our urban threshold is increasingly becoming topical. In Adelaide it is being driven by stormwater management strategies and economic efficiencies in a city that is beginning to embrace its Mediterranean environment, low water sustainability, and whether our showpiece public domains in Adelaide can afford large expanses of manicured lawns.

This paper reviews four projects in progress along the North Terrace in Adelaide. The first involves a major redesign of First Creek as it traverses Adelaide Botanic Garden to address stormwater management issues. The redesign includes strategies to control flash flooding, to cleanse stream water from pollutants, and to carefully incorporate a wetland system as an integral botanical and horticultural feature of a botanic garden. Further down North Terrace, the University of Adelaide is evaluating a scenario that will totally redesign Goodman Crescent, its picture-postcard promenade lawn. The scenario is to host an integrated water retention and water purification and cleansing system that will service independently of mains water an irrigation system and a waterfall. The proposal draws upon a similar strategy recently adopted by the South Australian Museum to capture and cleanse surface and roof water but place the installation and process on display as part of its overall biodiversity museum display that will unfold over the next five years under director Tim Flannery. The fourth example, in process at present, is to devise an integrated water system that may enable the Government House grounds to remove itself from dependence upon costly mains water to totally sustain its extensive gardens and lawns.

Importantly each project has similar threads: creative water maximization and purification use, and a desire to place these ‘installations’ on display as public statements of their commitment to water sustainability in Adelaide. But radically, here are four prominent cultural institutions readily willing to redefine the notion and traditional visual imagery of a ‘wetland’ on what is the main cultural boulevard of a capital city.

Exploring critical factors for achieving successful risk allocation in public-private partnership projects

Public Private Partnerships (PPP) as a procurement mechanism for infrastructure projects is becoming increasingly common. This is principally due to the value for money opportunities it offers the public sector sponsors. This value for money is primarily achieved through the optimisation of the allocation of risk inherent in the project being transferred from the public sector sponsors onto private sector bidders. This paper analyses the influence that these factors have on successful risk allocation with the aim of providing clearer parameters for optimal risk allocation in PPP projects. Through an extensive review of existing literature, the critical success factors for optimal risk allocation in PPP projects are identified. It is found that the optimisation of risk allocation in PPP projects is critically influenced by the identified factors, which will undoubtedly aid in the successful outcome for future PPP projects.

Factor analysis of partners' commitment to risk management in public-private partnership projects

Purpose – The purpose of this paper is to investigate and uncover key determinants that could explain partners' commitment to risk management in public-private partnership projects so that partners' risk management commitment is taken into the consideration of optimal risk allocation strategies.

Design/methodology/approach – Based on an extensive literature review and an examination of the purchasing power parity (PPP) market, an industry-wide questionnaire survey was conducted to collect the data for a confirmatory factor analysis. Necessary statistical tests are conducted to ensure the validity of the analysis results.

Findings – The factor analysis results show that the procedure of confirmatory factor analysis is statistically appropriate and satisfactory. As a result, partners' organizational commitment to risk management in public-private partnerships can now be determined by a set of components, namely general attitude to a risk, perceived one's own ability to manage a risk, and the perceived reward for bearing a risk.

Practical implications – It is recommended, based on the empirical results shown in this paper, that, in addition to partners' risk management capability, decision-makers, both from public and private sectors, should also seriously consider partners' risk management commitment. Both factors influence the formation of optimal risk allocation strategies, either by their individual or interacting effects. Future research may therefore explore how to form optimal risk allocation strategies by integrating organizational capability and commitment, the determinants and measurement of which have been established in this study.

Originality/value – This paper makes an original contribution to the general body of knowledge on risk allocation in large-scale infrastructure projects in Australia adopting the procurement method of public-private partnership. In particular, this paper has innovatively established a measurement model of organisational commitment to risk management, which is crucial to determining optimal risk allocation strategies and in turn achieving project success. The score coefficients of all obtained components can be used to construct components by linear combination so that commitment to risk management can be measured. Previous research has barely focused on this topic.
