Interpreting risk allocation mechanism in public-private partnership projects : an empirical study in a transaction cost economics perspective

Risk allocation in public-private partnership (PPP) projects is currently claimed as capability driven. While lacking theoretical support, the claim is often 'violated' by current industrial practice. There is thus a need for formal mechanisms to interpret why a particular risk is retained by government in one project while transferred to private partners in another. From the viewpoint of transaction cost economics (TCE), integrated with the resource-based view (RBV) of organizational capabilities, this paper proposed a theoretical framework for understanding risk allocation practice in PPP projects. The theories underlying the major constructs and their links were articulated. Data gathered from an industry-wide survey were used to test the framework. The results of multiple linear regression (MLR) generally support the proposed framework. It has been found that partners' risk management routine, mechanism, commitment, cooperation history, and uncertainties associated with project risk management could serve to determine the risk allocation strategies adopted in a PPP project. This theoretical framework thus provides both government and private agencies with a logical and complete understanding of the process of selecting the allocation strategy for a particular risk in PPP projects. Moreover, it could be utilized to steer the risk allocation strategy by controlling certain critical determinants identified in the study. Study limitations and future research directions have also been set out.

Automated identification of lung nodules

A system that can automatically detect nodules within lung images may assist expert radiologists in interpreting the abnormal patterns as nodules in 2D CT lung images. A system is presented that can automatically identify nodules of various sizes within lung images. The pattern classification method is employed to develop the proposed system. A random forest ensemble classifier is formed consisting of many weak learners that can grow decision trees. The forest selects the decision that has the most votes. The developed system consists of two random forest classifiers connected in a series fashion. A subset of CT lung images from the LIDC database is employed. It consists of 5721 images to train and test the system. There are 411 images that contained expert- radiologists identified nodules. Training sets consisting of nodule, non-nodule, and false-detection patterns are constructed. A collection of test images are also built. The first classifier is developed to detect all nodules. The second classifier is developed to eliminate the false detections produced by the first classifier. According to the experimental results, a true positive rate of 100%, and false positive rate of 1.4 per lung image are achieved.

Community development and ecology : engaging ecological sustainability through community development : selected papers from a conference held in Melbourne, 26-28 March 2008

The papers consider such questions as how to build community resilience in the context of profound environmental threat, how to ensure sustainability through community processes and how to assess community progress in responding to threats to the ecosystem.

‘CHOU GAGS CRITICS IN BANDOENG or how the media framed Premier Zhou Enlai at the Bandung Conference, 1955

At the Asian-African Conference at Bandung, Indonesia, in April 1955, the world's press concentrated its gaze on Premier Zhou Enlai of the People's Republic of China. Premier Zhou's every gesture, interaction and statement was scrutinized for evidence that his motivations at Bandung were antagonistic to Western interests. This preoccupation with the motivations of the Chinese was, however, no new phenomenon. By 1955, literary tropes of the ‘Yellow Peril’ had been firmly established in the Western imagination and, after 1949, almost seamlessly made their transition into fears of infiltrating communist Chinese ‘Reds’.

The first half of this paper explores the historical roots of the West's perceptions of the Chinese, through the literary works of Daniel Defoe to the pulp fiction of Sax Rohmer's Dr Fu Manchu series, which ran from 1917 to 1959. It then examines how this negative template was mobilised by the print media at the height of the Cold War to characterize Premier Zhou Enlai, not only as untrustworthy, but also as antagonistically anti-Western. This reading of representations of Premier Zhou at Bandung, as well as the literary tropes propagated in support of eighteenth and nineteenth-century imperial expansion, exposes a history of Western (mis)interpretations of China, and sheds light upon the media network's role in constructing a Chinese enemy in the mid-1950s.

Conceptualising, conducting and disseminating research for the 'public'

Drawing upon one research project Home-School-Community Partnerships for Enhancing Children's Numeracy Development we examine, critically, some problems entailed in the processes of conceptualizing the subjects and objects of inquiry, conducting field work with subjects (as knowing agents) and interpreting and disseminating the knowledge gained. Addressing these issues, in practice, has entailed some necessary consideration of fundamental tensions centred around the professional power-knowledge of teachers and a dominant cultural discourse that situates numeracy learning in the school.

A theoretical model (based upon Engeström's Activity Theory) was used to specify and analyse various types of partnerships within a network of mutually interconnected activities to support children's learning (Bloome et al., 2000; Engeström, 1999). By decentering the school, within this model, we have been led to a closer analysis of the concept of 'partnership' and of the social construction of parental and community involvement in children's numeracy development. One of the most problematic aspects of partnerships evident in our research is the way in which the term 'numeracy' is understood by different stakeholders. Awareness of this has shaped the conduct and dissemination of our research and ultimately enabled us to identify critical issues for further inquiry.

Acceptability, impact and sustainability of the national pilot quality assurance system for self management programs

Chronic condition self-management education and training interventions such as the Stanford Self Management Programs (SMP) have the capacity to improve health and quality of life of people with chronic conditions whilst reducing the use of health services. This is in line with the outcomes from the recent Council of Australian Governments’ meeting where it was indicated that self-management will be a centrepiece in forthcoming chronic disease initiatives.
Aim: report on a large national pilot quality assurance program involving the implementation and of an evaluation and quality monitoring system for SMPs including the provision of structured feedback to courses course leaders and service providers. During 2005/06 the quality assurance program was implemented at 11 diverse organisations across Australia. The program involved assisting organisations apply the 42-item Health Education Impact Questionnaire (HEIQ), a chronic disease health education outcome measure, and then observe and evaluate the value and impact of the quality program. Interviews with course leaders (n=60) and course participants (n=35) have elicited views about course quality and feedback processes.
Results: The evaluation revealed enablers and barriers to effective implementation and sustainability. Important enablers were:
- Course Leaders and organisations valued an Australia-wide system that provided feedback on course
quality and the impact on participants.
- Course Leaders were strongly personally motivated to respond appropriately to HEI-Q course
report feedback.
- Completing the questionnaire provided participants with the opportunity to reflect on issues that
emerge in the course content and reflect on their progression at the end of the SSMP.
Sustainability issues included:
- Organisations and course leaders require support, training and flexibility on how to administer and
manage the use of the HEI-Q.
- Availability of administrative resources in organisations to support the quality assurance activities.
- The requirement that course leaders are trained in interpreting HEI-Q course report data.
A quality improvement framework was developed which identified the actions required of key stakeholders to
support effective implementation.
Discussion: With the increasing endorsement of SMP across sectors it is important that course quality is known, is acceptable, and is communicated to stakeholders to inform and engender confidence in the SSMP. To effectively implement and sustain a quality improvement program for SMP, the processes and tools for measuring outcomes need to be responsive, flexible and easily integrated into the organisation and delivery of programs.
