Using technology to improve peer review and collaborative conversations to benchmark academic standards

In 2010 the Australian government commissioned the Australian Learning and Teaching Council (ALTC) to undertake a national project to facilitate disciplinary development of threshold learning standards. The aim was to lay the foundation for all higher education providers to demonstrate to the new national higher education regulator, the Tertiary Education Quality and Standards Agency (TEQSA), that graduates achieved or exceeded minimum academic standards. Through a yearlong consultative process, representatives of employers, professional bodies, academics and students, developed learning standards applying to any Australian higher education provider. Willey and Gardner reported using a software tool, SPARKPLUS, in calibrating academic standards amongst teaching staff in large classes. In this paper, we investigate the effectiveness of this technology to promote calibrated understandings with the national accounting learning standards. We found that integrating the software with a purposely designed activity provided significant efficiencies in calibrating understandings about learning standards, developed expertise and a better understanding of what is required to meet these standards and how best to demonstrate them. The software and supporting calibration and assessment process can be adopted by other disciplines, including engineering, seeking to provide direct evidence about performance against learning standards. © 2012 IEEE.

Exploring the utility of collaborative governance in a National Sport Organization running head: Collaborative sport governance

This paper presents the outcomes of an 18-month developmental action research study to enhance the governance capability of a national sport organization. Bowls Australia, the national governing body for lawn bowls
in Australia, includes nine independent state and territory member-associations. An intervention was designed and implemented with the Bowls Australia Board. The purpose of the intervention was to enact collaborative governance to overcome a perceived cultural malaise in the governance of the sport. This study is one of the first to examine collaborative governance in a federal sport structure. Results demonstrate the utility of collaborative governance to overcome adversarial national, member-state relations for the purpose of establishing a common and unifying vision for bowls, while also enhancing governance capability. This study identified the importance of collective board leadership in governance decision-making throughout the sport. It also highlights future research directions in relation to collective board leadership in federal governance structures.

Developing a collaborative model of industry feedback for work placement of business students

Work-integrated learning (WIL) is a signature feature of study in many higher education institutions. In business degrees, industry feedback is recognized as an integral part of the assessment of WIL, yet the role played by industry in appraising student performance in the workplace has not been clearly defined. Based on interviews with industry supervisors and academic mentors, this paper addresses the integration of academic and industry supervisor assessment practices designed to maximize student learning outcomes and capture the depth of the learning experiences during a work placement. A model of industry feedback was developed to incorporate planned assessment practices that achieve the learning outcomes agreed to at the start of the placement by all stakeholders: the student, the academic mentor and the industry supervisor.

Comparison of anthropometric measures as predictors of cancer incidence: a pooled collaborative analysis of 11 Australian cohorts

Obesity is a risk factor for cancer. However, it is not known if general adiposity, as measured by body mass index (BMI) or central adiposity [e.g., waist circumference (WC)] have stronger associations with cancer, or which anthropometric measure best predicts cancer risk. We included 79,458 men and women from the Australian and New Zealand Diabetes and Cancer Collaboration with complete data on anthropometry [BMI, WC, Hip Circumference (HC), WHR, waist to height ratio (WtHR), A Body Shape Index (ABSI)], linked to the Australian Cancer Database. Cox proportional hazards models assessed the association between each anthropometric marker, per standard deviation and the risk of overall, colorectal, post-menopausal (PM) breast, prostate and obesity-related cancers. We assessed the discriminative ability of models using Harrell's c-statistic. All anthropometric markers were associated with overall, colorectal and obesity-related cancers. BMI, WC and HC were associated with PM breast cancer and no significant associations were seen for prostate cancer. Strongest associations were observed for WC across all outcomes, excluding PM breast cancer for which HC was strongest. WC had greater discrimination compared to BMI for overall and colorectal cancer in men and women with c-statistics ranging from 0.70 to 0.71. We show all anthropometric measures are associated with the overall, colorectal, PM breast and obesity-related cancer in men and women, but not prostate cancer. WC discriminated marginally better than BMI. However, all anthropometric measures were similarly moderately predictive of cancer risk. We do not recommend one anthropometric marker over another for assessing an individuals' risk of cancer.

Understanding organ donation in the collaborative era: a qualitative study of staff and family experiences

BACKGROUND: Despite the success of the Breakthrough Collaborative Methodology (BCM) in increasing organ donation rates there has been little published evidence on the effect of the BCM on the wider attitudes and experiences of those involved in organ donation. This study sought to identify whether the National Organ Donation Collaborative in Australia had any additional influence on improving the experiences of staff and family members in the organ donation process. METHODS: IN-depth qualitative interviews with 17 family members from 13 families who had agreed to the organ donation of a deceased relative and 25 nurses and intensive care specialists at the Alfred Hospital, Melbourne, Victoria were carried out. RESULTS: The key factor in family members' decision to donate was prior knowledge of the deceased's donation wish. Although most family members did not regret their decision to donate, many were deeply dissatistified and, at times, confused by the technical and administrative nature of the donation process. Most staff members commented that the key community message about donation should be to encourage people to discuss donation rather than urging people to sign donor registers. CONCLUSION: This study identified valuable insights into the processes by which family members and intensive care unit staff deal with the actual processes of donation. Findings suggest that the process for families is far more complex than a simple agreement or refusal to donate. This study suggests that we should not assume that 'rates' of donation in Australia would increase merely through administrative programmes or marketing campaigns.

Creative architectural design with children: a collaborative design project informed by Rhodes's theory

Since the United Nations adopted the Convention on the Rights of the Child in 1989, there has been global consensus that children need to be involved in the planning and design of their environment. There exist various international initiatives that support collaborative design with children, with co-design projects conducted in different areas of the world. Evolving from the global context of co-design, this project explores creativity in relation to architectural design with children. Between October and December 2011, a team of architecture students from Deakin University worked with children from Roslyn Primary School (both institutions located in Victoria, Australia) to design a playground structure. Informed by Rhodes’s (1961) theory, creativity in this co-design project was addressed through the four dimensions of creative designers, creative context, creative process, and creative design outcomes. The findings of this study corroborate Rhodes’s theory of creativity, and suggest that it is useful to engender creative architectural design with children.

Evaluation of a collaborative operation to improve child sexual abuse reporting in Western Australian indigenous communities

This study presents an evaluation of Operation RESET, a community engagement intervention designed to help remote Indigenous communities and human service agencies to uncover, respond to, and prevent child sexual abuse. The primary aim of this evaluation was to determine whether the intervention was associated with increased reporting. Data were obtained for six Western Australian regions between 2007 and 2012. Number of reports and arrests significantly increased in the intervention areas during the intervention compared with the pre-intervention time period but not in the control areas. Arrest rates significantly increased during the intervention and increased further following the intervention. There were no changes in arrest rates in regions that did not participate in the operation. This evidence suggests that the reforms led to a marked improvement in some key outcomes for Indigenous victims of child sexual abuse and supports the adoption of this collaborative approach by other jurisdictions.

Modelling human preferences for ranking and collaborative filtering: a probabilistic ordered partition approach

Learning preference models from human generated data is an important task in modern information processing systems. Its popular setting consists of simple input ratings, assigned with numerical values to indicate their relevancy with respect to a specific query. Since ratings are often specified within a small range, several objects may have the same ratings, thus creating ties among objects for a given query. Dealing with this phenomena presents a general problem of modelling preferences in the presence of ties and being query-specific. To this end, we present in this paper a novel approach by constructing probabilistic models directly on the collection of objects exploiting the combinatorial structure induced by the ties among them. The proposed probabilistic setting allows exploration of a super-exponential combinatorial state-space with unknown numbers of partitions and unknown order among them. Learning and inference in such a large state-space are challenging, and yet we present in this paper efficient algorithms to perform these tasks. Our approach exploits discrete choice theory, imposing generative process such that the finite set of objects is partitioned into subsets in a stagewise procedure, and thus reducing the state-space at each stage significantly. Efficient Markov chain Monte Carlo algorithms are then presented for the proposed models. We demonstrate that the model can potentially be trained in a large-scale setting of hundreds of thousands objects using an ordinary computer. In fact, in some special cases with appropriate model specification, our models can be learned in linear time. We evaluate the models on two application areas: (i) document ranking with the data from the Yahoo! challenge and (ii) collaborative filtering with movie data. We demonstrate that the models are competitive against state-of-the-arts.

Privacy preserving collaborative filtering for KNN attack resisting

Privacy preserving is an essential aspect of modern recommender systems. However, the traditional approaches can hardly provide a rigid and provable privacy guarantee for recommender systems, especially for those systems based on collaborative filtering (CF) methods. Recent research revealed that by observing the public output of the CF, the adversary could infer the historical ratings of the particular user, which is known as the KNN attack and is considered a serious privacy violation for recommender systems. This paper addresses the privacy issue in CF by proposing a Private Neighbor Collaborative Filtering (PriCF) algorithm, which is constructed on the basis of the notion of differential privacy. PriCF contains an essential privacy operation, Private Neighbor Selection, in which the Laplace noise is added to hide the identity of neighbors and the ratings of each neighbor. To retain the utility, the Recommendation-Aware Sensitivity and a re-designed truncated similarity are introduced to enhance the performance of recommendations. A theoretical analysis shows that the proposed algorithm can resist the KNN attack while retaining the accuracy of recommendations. The experimental results on two real datasets show that the proposed PriCF algorithm retains most of the utility with a fixed privacy budget.

Interprofessional collaborative practice across Australasia: an emergent and effective community of practice

Individuals involved in fostering interprofessional collaborative practice in health are employed in the education, practice and political arenas. While the need to innovate and develop optimal training and practice is not new, the uniqueness of interprofessional collaborative practice is that it exists across professional backgrounds and transcends traditional hierarchies (entry-level to senior practitioners). As such, alternate models of support are required to assist champions to progress learning and innovation. One such model is a group of educators and practitioners networking across Australasia, resulting in the Australasian Community of Interprofessional Collaborative Practice (ACoIPCP). ACoIPCP is a lively community of practice (CoP) group across Australia and New Zealand, which is abreast of current activity in the relevant arenas and provides members with an avenue to share information and, therefore, respond appropriately to changes in the environment. Membership includes likeminded individuals who work in the area of interprofessional collaboration from a broad range of perspectives in both health education and practice. This paper describes the development of ACoIPCP and its aims, activities and achievements. By developing a community of practice framework in a cross-organisational environment, ACoIPCP members have been able to support one another, share resources, seek feedback and learn with and from one another to foster interprofessional collaborative practice within educational, clinical and political settings. Information about the processes and outcomes of ACoIPCP may provide guidance to others interested in facilitating learning and innovation through a community of practice model.
