The Relevance Of Emotional Intelligence For Leadership In A Higher Education Context, Dominique R. Parrish

Faculty of Science, Medicine and Health - Papers: part A

This paper reports on a case-study research investigation that sought to identify the relevance of emotional intelligence for effective higher education academic leadership. Semi-structured interviews were conducted, pre and post a leadership capacity development intervention, to gather broad data on participants' experiences, insights, and engagement in leadership and the utilisation of emotional intelligence in leading. The study found that emotional intelligence is recognised as a highly relevant and important requirement for academic leadership in higher education. Additionally, the investigation ascertained that emotional intelligence traits related to empathy, inspiring and guiding others and responsibly managing oneself were most applicable for academic …

Making Country Good: Stewardship And Environmental Change In Central Australian Pastoral Culture, Nicholas Gill

Faculty of Social Sciences - Papers (Archive)

Rural stewardship has been a focus of much natural resource management policy in Australia and elsewhere. Despite landowners professing stewardship, some researchers have cast doubt on the utility of the concept due to its vagueness and difficulties of associating attitudes with behaviour. In contrast I argue that stewardship should remain an important concept for understanding rural cultures, landholder practices and the politics of land. Stewardship, however, needs to be understood as emergent, as a 'dwelt achievement', as having temporal depth and as being part of the production of socio-natures. Moreover, as a key vernacular practice, its capacities and vulnerabilities require …

Carbon Dioxide Rebreathing In Respiratory Protective Devices: Influence Of Speech And Work Rate In Full-Face Masks, Carmen L. Smith, Jane L. Whitelaw, Brian Davies

Faculty of Science, Medicine and Health - Papers: part A

Carbon dioxide (CO2) rebreathing has been recognised as a concern regarding respirator use and is related to symptoms of discomfort, fatigue, dizziness, headache, muscular weakness and drowsiness. Previous investigations are limited by small sample size and have not evaluated the relationship between CO2 inhalation and phonic respiration (breathing during speech) in respiratory protective devices (RPDs). A total of 40 workers trained in the use of RPDs performed a graded exercise test on a cycle ergonometer that increased in workload every 5 min. During the third minute of each stage, participants read aloud a prepared text. Measures of mixed expired CO2 …

Are Low-Skill Public Sector Workers Really Overpaid? A Quasi-Differenced Panel Data Analysis, Peter Siminski

Faculty of Commerce - Papers (Archive)

Public–private sectoral wage differentials have been studied extensively using quantile regression techniques. These typically find large public sector premiums at the bottom of the wage distribution. This may imply that low skill workers are ‘overpaid’, prompting concerns over efficiency. We note several other potential explanations for this result and explicitly test whether the premium varies with skill, using Australian data. We use a quasi-differenced Generalized Method of Moments (GMM) panel data model which has not been previously applied to this topic, internationally. Unlike other available methods, this technique identifies sectoral differences in returns to unobserved skill. It also facilitates a …

Application Of The Task-Technology Fit Model To Structure And Evaluate The Adoption Of E-Books By Academics, John D'Ambra, Concepcion S. Wilson, Shahriar Akter

Faculty of Commerce - Papers (Archive)

Increasingly, e-books are becoming alternatives to print books in academic libraries, thus providing opportunities to assess how well the use of e-books meets the requirements of academics. This study uses the task-technology fit (TTF) model to explore the interrelationships of e-books, the affordances offered by smart readers, the information needs of academics, and the "fit" of technology to tasks as well as performance. We propose that the adoption of e-books will be dependent on how academics perceive the fit of this new medium to the tasks they undertake as well as what added-value functionality is delivered by the information technology …

'Reel Love' Across Ethnic Boundaries? The Extent And Significance Of Inter-Ethnic Intimacy In Australian Cinema, Natascha Klocker, Elyse Stanes

Faculty of Science, Medicine and Health - Papers: part A

National cinemas play an important role in the construction of national identities, representing the 'self' to both domestic and international audiences. Evidence of the material impacts of media representations on individuals and society, and the pervasiveness of movie-watching as a cultural activity, underscore the importance of scholarly inquiry into film. Here, we are concerned with how ethnic diversity has been negotiated within the Australian national cinema - specifically at the scale of intimate interpersonal relationships. Our analysis of twenty-five recent Australian films considers how cinema alerts audiences to the possibilities and limitations of love within and across ethnic boundaries. We …

Computerisation Of Perinatal Data Entry: Is The Data Accurate?, Alison Craswell, Lorna Moxham, Marc Broadbent

Faculty of Science, Medicine and Health - Papers: part A

Perinatal data (PD) is collected for mothers and babies Australia wide as mandated at a federal level. The data is used to monitor patterns in midwifery, obstetric and neonatal practice and health outcomes and is also used for research purposes, funding allocation and the education of midwives and medical officers. Accuracy in PD is most often reported via quantitative validation studies of PD collections both internationally and within Australia [1]. These studies report varying levels of accuracy in PD collection and suggest researchers need to be more aware of the quality of data they use. This paper presents findings from …

Faculty of Social Sciences - Papers (Archive)

Parents often express concerns about that technology, particularly video has on their children. Indeed, have been associated with problems social isolation and a drop-off in academic achievement, and games containing violence shown to increase aggressive thoughts and. Frequent interaction with video games been associated with subsequent problems functions such as attention and impulse-control However, it is important to note that technology and video games can also be used to improve behavior. During my 15 years of research examining the brain electrical activity and behavior of children with Attention Deficit Hyperactivity Disorder (ADHD), there has been an increase in the use …

Alcohol Advertising During Televised Australian Football Finals, Sandra C. Jones, Lance Barrie, Michael Chapman, Nicholas J. Corr, Sondra Davoren

Faculty of Social Sciences - Papers (Archive)

Alcohol marketing during sport, and alcohol industry sponsorship of sporting events, is highly lucrative; however, concerns have been raised over the impact on child and adolescent viewers of repeated exposure to alcohol marketing messages. The aim of this research project was to investigate the amount and type of alcohol marketing during two major sporting events in 2012 - the semi-finals and grand final of the AFL and NRL. The broadcasts of these six games were audited for alcohol advertisements and other advertising communications. Almost one-fifth of the screen time included alcohol marketing. Policy and practice implications of these findings are …

Preliminaries To Haptic-Integrated Pronunciation Instruction, William Acton, Amanda Ann Baker, Michael Burri, Brian Teaman

Faculty of Social Sciences - Papers (Archive)

This paper reports on aspects of a haptic (movement plus touch) integrated system for classroom pronunciation instruction. It is based, in part, on established pedagogical practice in the use of somatic/kinesthetic techniques such as gesture in language instruction (Acton, 1984, 2012; Celce-Murcia, Brinton, Goodwin & Briner, 2010; McCafferty, 2004), and management of vocal resonance in singing and voice training (Lessac, 1997). The pedagogical method is designed for use by relatively untrained instructors and is generally best delivered through video with classroom follow up. Relatively recent research and development in haptics, especially in the areas of gaming, prosthetics and robotics, provides …

Faith-Based Substance Abuse Programs, Geoffrey C. B Lyons, Frank P. Deane, Peter J. Kelly

Faculty of Social Sciences - Papers (Archive)

Faith-based programs are one of the primary treatment options for individuals with substance use disorders. However, there is ambiguity regarding what faith-based programs are, how they differ from secular programs, and how they incorporate religion or spirituality into treatment. Furthermore, though evidence suggests faith-based programs can be as effective as other secular treatments, it is unclear how the utilization of religion or spirituality in the treatment process influences recovery outcomes. Preliminary research suggests that the exploration and cultivation of spirituality may operate on recovery by improving a client's psychological well-being, social support systems, and the ability to cope with distress.

Factors Associated With Differences In Quit Rates Between 'Specialist' And 'Community' Stop-Smoking Practitioners In The English Stop-Smoking Services, Mairtin S. Mcdermott, Emma Beard, Leonie S. Brose, Robert West, Andy Mcewen

Faculty of Engineering and Information Sciences - Papers: Part A

Introduction: Behavioral support improves smokers' chances of quitting, but quit rates are typically lower for smokers supported by "community practitioners" for whom smoking cessation is a small part of their job than for those supported by "specialist practitioners" for whom it is the main role. This article examined the factors that might contribute to this. Method: A total of 573 specialist practitioners and 466 community practitioners completed a 42-item online survey that covered demographic and employment information, current practices, levels of training, and 4-week CO-verified quit rates. Responses were compared for community and specialist practitioners. Mediation analysis was undertaken to …

Identity-Based Data Storage In Cloud Computing, Jinguang Han, Willy Susilo, Yi Mu

Faculty of Engineering and Information Sciences - Papers: Part A

Identity-based proxy re-encryption schemes have been proposed to shift the burden of managing numerous files from the owner to a proxy server. Nevertheless, the existing solutions suffer from several drawbacks. First, the access permission is determined by the central authority, which makes the scheme impractical. Second, they are insecure against collusion attacks. Finally, only queries from the same domain (intra-domain) are considered. We note that one of the main applications of identity-based proxy re-encryption schemes is in the cloud computing scenario. Nevertheless, in this scenario, users in different domains can share files with each other. Therefore, the existing solutions do …

A Decentralized Service Discovery Approach On Peer-To-Peer Network, Qiang He, Jun Yan, Yun Yang, Ryszard Kowalczyk, Hai Jin

Faculty of Engineering and Information Sciences - Papers: Part A

Service-Oriented Computing (SOC) is emerging as a paradigm for developing distributed applications. A critical issue of utilizing SOC is to have a scalable, reliable, and robust service discovery mechanism. However, traditional service discovery methods using centralized registries can easily suffer from problems such as performance bottleneck and vulnerability to failures in large scalable service networks, thus functioning abnormally. To address these problems, this paper proposes a peer-to-peer-based decentralized service discovery approach named Chord4S. Chord4S utilizes the data distribution and lookup capabilities of the popular Chord to distribute and discover services in a decentralized manner. Data availability is further improved by …

Gestural Interface Technology In Early Childhood Education: A Framework For Fully Engaged Communication, Holly Tootell, Melinda Plumb, Colin D. Hadfield, Linda Dawson

Faculty of Engineering and Information Sciences - Papers: Part A

Gestural Interface Technology (GIT) has changed the way technology is adopted in classrooms for all ages. The accessibility of control through touch means that technology such as Apple's iPad can be used in early childhood education. In this paper, we introduce a framework for fully-engaged communication, developed from educational pedagogy and critical engagement in information systems. The intersection of these dimensions creates a view of a GIT lifeworld approach which allows it to be used to understand multiple layers of engagement that exist within an early childhood education environment.

Efficient Linkable And/Or Threshold Ring Signature Without Random Oracles, Tsz Hon Yuen, Joseph K. Liu, Man Ho Au, Willy Susilo, Jianying Zhou

Faculty of Engineering and Information Sciences - Papers: Part A

Linkable ring signatures have found many attractive applications. One of the recent important extensions is a linkable threshold ring signature (LTRS) scheme. Unfortunately, the existing LTRS schemes are only secure in the random oracle model (ROM). In this paper, we make the following contributions. First, we construct the first LTRS scheme that is secure without requiring the ROM. Further, we enhance the security of a threshold ring signature (for both linkable or non-linkable) by providing a stronger definition of anonymity. This strengthened notion makes threshold ring signature schemes more suitable in real life. Finally, we provide efficient schemes that outperform …

Algorithm Portfolios For Logistics Optimization Considering Stochastic Demands And Mobility Allowance, N Shukla, A K. Choudhary, P Prakash, K J. Fernandes, M K. Tiwari

Faculty of Engineering and Information Sciences - Papers: Part A

The vehicle routing problem with stochastic demand (VRPSD) is a well known NP-hard problem. The uncharacteristic behaviour associated with the problem enhances the computational efforts required to obtain a feasible and near-optimal solution. This paper proposes an algorithm portfolio methodology based on evolutionary algorithms, which takes into account the stochastic nature of customer demand to solve this computationally complex problem. These problems are well known to have computationally complex objective functions, which make their solutions hard to find, particularly when problem instances of large dimensions are considered. Of particular importance in such situations is the timeliness of the solution. For …

Evidence-Free Policy: The Case Of The National Injury Insurance Scheme, Mark Harrison

Faculty of Engineering and Information Sciences - Papers: Part A

The Productivity Commission report 'Disability Care and Support' recommends tort liability be replaced by a compulsory, government-run, no-fault scheme. But theory and evidence indicate moving to a no-fault scheme will increase the accident rate. Even a move from non-risk-rated third-party insurance to non-risk-rated first-party insurance reduces incentives for care. A no-fault scheme is not superior to current policies; genuine reform will need to be informed by law and economics literature.

Self-Adaptation-Based Dynamic Coalition Formation In A Distributed Agent Network: A Mechanism And A Brief Survey, Dayong Ye, Minjie Zhang, Danny Sutanto

Faculty of Engineering and Information Sciences - Papers: Part A

In some real systems, e.g., distributed sensor networks, individual agents often need to form coalitions to accomplish complex tasks. Due to communication and computation constraints, it is infeasible for agents to directly interact with all other agents to form coalitions. Most previous coalition formation studies, however, overlooked this aspect. Those studies did not provide an explicitly modeled agent network or assumed that agents were in a fully connected network, where an agent can directly communicate with all other agents. Thus, to alleviate this problem, it is necessary to provide a neighborhood network structure, within which agents can directly interact only …

Strong Amicable Orthogonal Designs And Amicable Hadamard Matrices, Jennifer Seberry

Faculty of Engineering and Information Sciences - Papers: Part A

Amicable orthogonal designs have renewed interest because of their use in mobile communications. We show the existence of strong amicable orthogonal designs, AOD(n: 1, n - 1; 1, n - 1), for n = pr + 1, p ≡ 3 (mod 4) a prime and for n = 2r, n a non-negative integer in a form more suitable for communications. Unfortunately the existence of amicable Hadamard matrices is not enough to demonstrate the existence of strong amicable orthogonal designs.

The Role Of Public Procurement In Improving Accessibility To Ict, Gunela Astbrink, William Tibben

Faculty of Engineering and Information Sciences - Papers: Part A

Government bodies use public procurement policies and mechanisms to purchase ICT products and services. Some governments in OECD countries apply accessibility criteria when procuring ICT to improve access to their services and employment opportunities for people with disabilities. This may have a flow-on effect of greater availability of affordable and accessible ICT thus improving digital inclusion. This paper outlines research on comparative analysis of the situation in Australia with current policy in OECD countries. The research resulted in recommendations for a consumer-oriented plan to work with Australian governments on the introduction of accessibility criteria in ICT public procurement.

Model-Driven Disaster Management, Siti Hajar Othman, Ghassan Beydoun

Faculty of Engineering and Information Sciences - Papers: Part A

Disaster management (DM) is a challenging domain to model because of the variety of dynamic characteristics attached to the domain. Metamodeling is a model-driven approach that describes how semantic domain models can be built into an artifact called a Metamodel. By collecting all the domain concepts and partitioning the domain problems into sub-domain-problems, a metamodel can produce a domain-specific language. This paper presents a Disaster Management Metamodel that can serve as a representational layer of DM expertise. This metamodel leads to better knowledge sharing and facilitates combining and matching different DM activities to best manage the disaster on hand.

Performance Evaluation Of Cooperative Communications For Stfc Mb-Ofdm Uwb, Zixuan Lin, Le Chung Tran, Farzad Safaei

Faculty of Engineering and Information Sciences - Papers: Part A

Recently, the combination of cooperative communication, Space-Time-Frequency Codes (STFCs) and Multiband OFDM Ultra-Wideband (MB-OFDM UWB) has been proposed to improve the data rate, system capacity and reliability. This paper provides insightful performance evaluation for our previous proposed cooperative communication schemes for MBOFDM UWB systems. In particular, this paper shows that the usefulness of cooperative communication schemes is decided by the mutual relation between the signal-to-noise ratio (SNR) of the inter-node links, referred to as inter-node SNR, and that of the uplinks, which is referred to as uplink SNR. For a certain uplink SNR value, cooperative communication becomes useful when the …

Security Analysis Of A Distributed Reprogramming Protocol For Wireless Sensor Networks, Yong Yu, Jianbing Ni, Ying Sun

Faculty of Engineering and Information Sciences - Papers: Part A

Reprogramming for wireless sensor networks is essential to upload new code or to alter the functionality of existing code. To overcome the weakness of the centralized approach of the traditional solutions, He et al. proposed the notion of distributed reprogramming where multiple authorized network users are able to reprogram sensor nodes without involving the base station. They also gave a novel distributed reprogramming protocol called SDRP by using identity-based signature, and provided a comprehensive security analysis for their protocol. In this letter, unfortunately, we demonstrate that SDRP is insecure as the protocol fails to satisfy the property of authenticity and …

Optimal Design Of An Ultrasmall Soi-Based 1 X 8 Flat-Top Awg By Using An Mmi, Hongqiang Li, Yaoting Bai, Xiaoyi Dong, Enbang Li, Yang Li, Yu Liu, Wenqian Zhou

Faculty of Engineering and Information Sciences - Papers: Part A

Four methods based on a multimode interference (MMI) structure are optimally designed to flatten the spectral response of silicon-on-insulator- (SOI-) based arrayed-waveguide grating (AWG) applied in a demodulation integration microsystem. In the design for each method, SOI is selected as the material, the beam propagation method is used, and the performances (including the 3 dB passband width, the crosstalk, and the insertion loss) of the flat-top AWG are studied. Moreover, the output spectrum responses of AWGs with or without a flattened structure are compared. The results show that low insertion loss, crosstalk, and a flat and efficient spectral response are …

Systematic Network Design For Liner Shipping Services, Shuaian Wang, Zhiyuan Liu, Qiang Meng

Faculty of Engineering and Information Sciences - Papers: Part A

A systematic design for a liner shipping network was addressed. Many practical features in real-world operations, including multiple types of containers, container transshipment operations, empty container repositioning, origin-to-destination transit time constraints, consistent services with the current network, and joint services with other liner shipping companies, were considered. Given a set of candidate ship routes, some of these routes had to be used, and the use of others was optional. A mixed-integer linear programming model was proposed for the selection of optional ship routes. The solution of this model provided the laden and empty container flow on the selected ship routes. …

Noise Robust Keyword Spotting For User Generated Video Blogs, M S. Barakat, C H. Ritz, D A. Stirling

Faculty of Engineering and Information Sciences - Papers: Part A

This paper presents a template-based system for speaker independent key word spotting (KWS) in continuous speech that can help in automatic analysis, indexing, search and retrieval of user generated videos by content. Extensive experiments on clean speech confirm that the proposed approach is superior to a HMM approach when applied to noisy speech with different signal-to-noise ratio (SNR) levels. Experiments conducted to detect swear words, personal names and product names within a set of online user generated video blogs shows significantly better recall and precision results compared to a traditional ASR-based approach.

A Secure And Effective Anonymous User Authentication Scheme For Roaming Service In Global Mobility Networks, Fentong Wen, Willy Susilo, Guomin Yang

Faculty of Engineering and Information Sciences - Papers: Part A

In global mobility networks, anonymous user authentication is an essential task for enabling roaming service. In a recent paper, Jiang et al. proposed a smart card based anonymous user authentication scheme for roaming service in global mobility networks. This scheme can protect user privacy and is believed to have many abilities to resist a range of network attacks, even if the secret information stored in the smart card is compromised. In this paper, we analyze the security of Jiang et al.'s scheme, and show that the scheme is in fact insecure against the stolen-verifier attack and replay attack. Then, we …

Scalable Fragile Watermarking For Image Authentication, Angela Piper, Reihaneh Safavi-Naini

Faculty of Engineering and Information Sciences - Papers: Part A

Semi-fragile watermarks are used to detect unauthorised changes to an image, whereas tolerating allowed changes such as compression. Most semi-fragile algorithms that tolerate compression assume that because compression only removes the less visually significant data from an image, tampering with any data that would normally be removed by compression cannot affect a meaningful change to the image. Scalable compression allows a single compressed image to produce a variety of reduced resolution or reduced quality images, termed subimages, to suit the different display or bandwidth requirements of each user. However, highly scaled subimages remove a substantial fraction of the data in …
