Objective: To describe the distribution of carotenoid intakes and important food sources of carotenoids in the diet of a representative population of older Australians.

Design: Population-based cohort study.

Setting: Two post-code areas in the Blue Mountains, west of Sydney, Australia.

Subjects: We studied 2012 (86%) of the 2334 participants aged 55 + years attending the 5-year follow-up of the cross-sectional Blue Mountains Eye Study (BMES), who completed a detailed semi-quantitative food-frequency questionnaire. The intakes for five carotenoids were studied: α-carotene, β-carotene, β-cryptoxanthin, lutein and zeaxanthin combined, and lycopene.

Results: The mean intake per day for each carotenoid was: α-carotene, 2675 …

Migration, Music And Social Relations On The Nsw Far North Coast, Christopher Gibson

Faculty of Social Sciences - Papers (Archive)

This article explores urban-rural migration on the NSW Far North Coast (the ‘Northern Rivers’ region) and the emergence of popular music as a niche cultural industry. The various images of the NSW Far North Coast as a ‘lifestyle’ region, ‘alternative’ region and coastal retreat have attracted a diverse mix of exurban professionals, unemployed persons, youth subcultures and retirees, yet despite population growth, the region continues to suffer unemployment rates among the highest in Australia. Against this backdrop, popular music has emerged as a niche industry with linkages to cultural production in Sydney, Melbourne and overseas, and also an area of …

Can The Q Link Ally R, A Form Of Sympathetic Resonance Technology (Srttm), Attenuate Acute Mobile Phone-Related Changes To Neural Function?, Rodney J. Croft, Jody Chandler, Adrian P. Burgess, Robert Barry, John D. Williams, Adam Clarke

Faculty of Social Sciences - Papers (Archive)

Objectives: Exposure to active mobile phones (MP) has been shown to affect human neural function as shown by the electroencephalogram (EEG). Although it has not been determined whether such effects are harmful, a number of devices have been developed that attempt to minimize these MP-related effects. One such device, the Q Link Ally^® (QL; Clarus Products, International, L.L.C., San Rafael, CA), is argued to affect the human organism in such a way as to attenuate the effect of MPs. The present pilot study was designed to determine whether there is any indication that QL does alter MP-related effects on …

Design And Implementation Of A Content Filtering Firewall, Rongbo Du, Rei Safavi-Naini, Willy Susilo

Faculty of Engineering and Information Sciences - Papers: Part A

A firewall is a system for enforcing access control policy between two networks and is one of the most important measures to protect against network attacks. Firewalls traditionally protect the internal network from outside threats. But there has been increasing need for preventing the misuses of the network by the internal users which most previous firewalls overlook. In this paper, we propose a method of adding content filtering functionality to the firewall and describe its implementation. We also show a new attack that combines JAVA Applet and XML to get around the content filtering firewall, hence showing the need for …

The Two-Prime Analogue Of The Hecke C*-Algebra Of Bost And Connes, Nadia Larsen, Ian Putnam, Iain Raeburn

Faculty of Engineering and Information Sciences - Papers: Part A

Let p and q be distinct odd primes. We analyse a semigroup crossed product C * (G p,q) α 2 similar to the semigroup crossed product which models the Hecke C * -algebra of Bost and Connes. We describe a composition series of ideals in C * (G p,q) α 2 , and show that the structure of one of the subquotients reflects interesting number-theoretic information about the multiplicative orders of q in the rings Z/p^l Z.

Regularity Of Induced Representations And A Theorem Of Quigg And Speilberg, Astrid An Huef, Iain Raeburn

Faculty of Engineering and Information Sciences - Papers: Part A

Mackey's imprimitivity theorem characterizes the unitary representations of a locally compact group G which have been induced from representations of a closed subgroup K; Rieffel's influential reformulation says that the group C*-algebra C*(K) is Morita equivalent to the crossed product C₀(G/K)×G [14]. There have since been many important generalizations of this theorem, especially by Rieffel [15, 16] and by Green [3, 4]. These are all special cases of the symmetric imprimitivity theorem of [11], which gives a Morita …

Mr Damper And Its Application For Semi-Active Control Of Vehicle Suspension System, G Z. Yao, F F. Yap, G Chen, Weihua Li, S H. Yeo

Faculty of Engineering and Information Sciences - Papers: Part A

In this paper, a semi-active control of vehicle suspension system with magnetorheological (MR) damper is presented. At first a MR damper working in flow mode is designed. Performance testing is done for this damper with INSTRON machine. Then a mathematical model, Bouc–Wen model, is adopted to characterize the performance of the MR damper. With optimization method in MATLAB^® and experimental results of MR damper, the coefficients of the model are determined. Finally, a scaled quarter car model is set up including the model of the MR damper and a semi-active control strategy is adopted to control the vibration of …

Product Systems Over Right-Angled Artin Semigroups, Neal J. Fowler, Aidan Sims

Faculty of Engineering and Information Sciences - Papers: Part A

We build upon MacLane's definition of a tensor category to introduce the concept of a product system that takes values in a tensor groupoid G. We show that the existing notions of product systems fit into our categorical framework, as do the k-graphs of Kumjian and Pask. We then specialize to product systems over right-angled Artin semigroups; these are semigroups that interpolate between free semigroups and free abelian semigroups. For such a semigroup we characterize all product systems which take values in a given tensor groupoid G. In particular, we obtain necessary and sufficient conditions under which a collection of …

Mtd Method For Better Prediction Of Sea Surface Temperature, Velappa Ganapathy, K Meena, Kashem M. Muttaqi

Faculty of Engineering and Information Sciences - Papers: Part A

A class of incremental learning procedures known as the Modified Temporal Difference (MTD) method is introduced in this paper for fixed-step prediction problems which uses the functional features of Multilayer Perceptron. The method is applied for weekly prediction of the Sea Surface Temperature (SST) from oceanographic data. Temporal Difference (TD) methods suggest how each output of a temporal sequence must be changed, whereas a back-propagation algorithm decides which part(s) of a network to change in order to influence its output and reduce the overall error. In other words, TD methods and back-propagation address temporal credit and structural credit assignment issues, …

Mechanically Alloyed Amorphous Ti50(Cu0.45ni0.55)44-X Alxsi4b2 Alloys With Supercooled Liquid Region, L C. Zhang, Jian Xu, E Ma

Faculty of Engineering and Information Sciences - Papers: Part A

A high-energy ball milling procedure has been developed to produce amorphous alloys in Ti₅₀(Cu_0.45Ni_0.55)_44−xAl_xSi₄B₂ (x= 0, 4, 8, 12) powder mixtures. The milling products were characterized using x-ray diffraction, differential scanning calorimetry, and transmission electron microscopy. The Ti-based amorphous alloy powders prepared through this solid-state process exhibit a well-defined glass transition and a supercooled liquid region (ΔT_x =64 K) close to the largest achieved so far for Ti-based undercooled melts. The substitution of Al for Cu and Ni has beneficial effects on …

Environmentalists Help Manage Corporate Reputation: Changing Perceptions Not Behaviour, Sharon Beder

Faculty of Arts - Papers (Archive)

Environmentalists have traditionally drawn attention to environmental problems by highlighting corporate misdeeds and thereby damaged the good reputation of those companies. However, nowadays those very corporations are drawing on environmentalists to help repair their reputations. Nike and BP are two examples of companies that have adopted some environmental reforms as part of their reputation management strategies and received the praise of environmental groups for doing so. Yet both continue with the practices that earned them poor reputations in the first place. Clearly the role of environmentalists in working with such companies is misguided and ineffective in terms of long-term environmental …

Remembrance Of Things That Last, Anthony Ashbolt

Faculty of Arts - Papers (Archive)

For some years now, the 1960s have been contested terrain. Many commentators have rushed to specious judgements about the radical politics of the era, while others have struggled valiantly to keep memories alive. Much of the politics of the contemporary epoch is being played out through the lens of the Sixties. This seems like a grand and foolish claim but it needs to be understood that the so-called neo-liberal and/or neoconservative agenda (and I will include hawkish foreign policy in this) is substantially directed at burying the Sixties. The gains of the various social movements, in particular the anti-war and …

Book Review Of: Sound Technology And The American Cinema, Brian M. Yecies

Faculty of Arts - Papers (Archive)

Sound technology and the American cinema makes an exciting contribution to the fields of film history, film theory, and cultural studies. It offers an in-depth, multi-sourced study of the development of representational technologies, including photography, phonography, and the cinema; each had a convergent role in the permanent adoption of sound into the Hollywood film industry. James Lastra intrigues the reader by constructing a technological genealogy, which connects the ideas and sensibilities of an American culture on the brink of modernity. In doing so, he brings to life a material history of this century's "most influential audiovisual form-the classical Hollywood sound …

A Classification Of Intersection Type Systems, Martin W. Bunder

Faculty of Engineering and Information Sciences - Papers: Part A

The first system of intersection types. Coppo and Dezani [3], extended simple types to include intersections and added intersection introduction and elimination rules ((ΛI ) and (ΛE) ) to the type assignment system. The major advantage of these new types was that they were invariant under β-equality, later work by Barendregt, Coppo and Dezani [1], extended this to include an (η) rule which gave types invariant under βη-reduction.

Urzyczyn proved in [6] that for both these systems it is undecidable whether a given intersection type is empty. Kurata and Takahashi however have shown in [5] …

Can We Teach Problem Solving In A Clinical Nursing Laboratory?, E Ashcroft

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

Can we teach problem solving in a clinical nursing laboratory? Elfi Ashcroft Technical Officer & Nursing Laboratory Manager University of Wollongong Abstract: The objectives of clinical nursing laboratories are the acquisition of psychomotor skills and the simulation of realistic clinical situations (Reilly and Oerman, 1992). A successful educational experience should also encourage the student to identify their development needs and initiate their own learning response (Neary, 2000). Laboratory classes are congested with factual information and demonstration (show and tell). Students, however, rarely have enough time to explore equipment and to acquire technical problem solving skills. The idea to develop a …

Faculty of Social Sciences - Papers (Archive)

This extended study, with both quantitative and qualitative elements, was designed and carried out in 1999-2000 to collect baseline data on refugee women's experiences, expressed needs and perspectives of the existing care services in order to inform the development of relevant maternity care policies for this vulnerable group and to plan models of best practice for the future.

A Sub-Vector Weighting Scheme For Image Retrieval With Relevance Feedback, Lei Wang, Kap Luk Chan, Xuejian Xiong

Faculty of Engineering and Information Sciences - Papers: Part A

In this paper, a sub-vector weighting scheme is proposed for the case of small sample in image retrieval with relevance feedback. By partitioning a multi-dimensional visual feature vector to multiple sub-vectors, the singularity problem caused by small sample can be avoided by the lower dimensionality of the sub-vectors. Then the optimal weighting can be performed on these sub-vectors respectively and the similarity scores obtained are combined as the final score to rank the database images. Experimental results demonstrated that the proposed weighting scheme can significantly improve the efficacy of image retrieval with relevance feedback.

Environmental Factors Associated With Adults' Participation In Physical Activity: A Review, Nancy Humpel, Neville Owen, Eva Leslie

Faculty of Social Sciences - Papers (Archive)

Background: Promoting physical activity is a public health priority, and changes in the environmental contexts of adults’ activity choices are believed to be crucial. However, of the factors associated with physical activity, environmental influences are among the least understood. Method: Using journal scans and computerized literature database searches, we identified 19 quantitative studies that assessed the relationships with physical activity behavior of perceived and objectively determined physical environment attributes. Findings were categorized into those examining five categories: accessibility of facilities, opportunities for activity, weather, safety, and aesthetic attributes. Results: Accessibility, opportunities, and aesthetic attributes had significant associations with physical activity. …

Knowledge About Typical Source Output Influences Perceived Auditory Distance, John W. Philbeck, Donald H. Mershon

Faculty of Social Sciences - Papers (Archive)

Vocal effort is known to influence the judged distance of speechsound sources. The present research examined whether this influence is due to long-term experience gained prior to the experiment versus short-term experience gained from exposure to speech stimuli earlier in the same experiment. Speech recordings were presented to 192 blindfolded listeners at three levels of vocal output. Even upon the first presentation, shouting voices were reported as appearing farthest, whispered voices closest. This suggests that auditory distance perception can be affected by past experience in a way that does not require explicit comparisons between individual stimuli.

Can Motivational Signs Prompt Increases In Incidental Physical Activity In An Australian Health-Care Facility?, A L. Marshall, A E. Bauman, C Patch, J Wilson, J Chen

Faculty of Health and Behavioural Sciences - Papers (Archive)

This study aimed to evaluate whether a stairpromoting signed intervention could increase the use of the stairs over the elevator in a health-care facility. A time-series design was conducted over 12 weeks. Data were collected before, during and after displaying a signed intervention during weeks 4–5 and 8–9. Evaluation included anonymous counts recorded by an objective unobtrusive motion-sensing device of people entering the elevator or the stairs. Self-report data on stair use by hospital staff were also collected. Stair use significantly increased after the first intervention phase (P 0.02), but after the intervention was removed stair use decreased back towards …

Surface Reflectance Properties Of Antarctic Moss And Their Relationship To Plant Species, Pigment Composition And Photosynthetic Function, C. E. Lovelock, Sharon A. Robinson

Faculty of Science - Papers (Archive)

We investigated how surface reflectance properties and pigment concentrations of Antarctic moss varied over species, sites, microtopography, and with water content. We found that species had significantly different surface reflectance properties, particularly in the region of the red edge (approximately 700 nm), but this did not correlate strongly with pigment concentrations. Surface reflectance of moss also varied in the visible region and in the characteristics of the red edge over different sites. Reflectance parameters, such as the Photochemical Reflectance Index (PRI) and Cold Hard Band (CBH) were useful discriminators of site, microtopographic position and water content. The PRI was correlated …

P300 Amplitude Is Determined By Target-To-Target Interval, C. J. Gonsalvez, J. Polich

Faculty of Health and Behavioural Sciences - Papers (Archive)

P300 event-related brain potential (ERP) measures are affected by target stimulus probability, the number of nontargets preceding the target in the stimulus sequence structure, and interstimulus interval (ISI). Each of these factors contributes to the target-to-target interval (TTI), which also has been found to affect P300. The present study employed a variant of the oddball paradigm and manipulated the number of preceding nontarget stimuli (0, 1, 2, 3) and ISI (1, 2, 4 s) in order to systematically assess TTI effects on P300 values from auditory and visual stimuli. Number of preceding nontargets generally produced stronger effects than ISI in …

The Effect Of Fire Simulation On Clothing And Tissue Temperatures, Alison L. Fogarty, Karen A. Armstrong, Brian F. Woods, Nigel A. S Taylor

Faculty of Health and Behavioural Sciences - Papers (Archive)

A series of field trials was undertaken to evaluate the thermal properties of five different personal protective ensembles, under more realistic experimental conditions. This project was designed to address the following applied questions, which could assist in the selection of suitable ensembles for the New South Wales Fire Brigades: (a) Are there between-ensemble differences in the storage of metabolically-produced heat? (b) Are there between-ensemble differences in physiological strain during real-task simulations? (c) Are there between-ensemble differences in the penetration of external heat? These field trials included two simulated fire exposures (Hot Fire Cell and Flashover Simulator), during which, from a …

The Effect Of Individual Psychological Characteristics In The Use Of Computerised Information Systems, Farideh Yaghmaie, Peter Caputi, Rohan Jayasuriya

Faculty of Health and Behavioural Sciences - Papers (Archive)

Investments in computerised information systems in the health industry in evident in most parts of the world. In hospitals and other Healthcare settings, increasingly, hands-on computer use is becoming an important behaviour for effective job perfonnance for health professionals. As the pre-employment (professional) training is provided at a number of different settings the exposure health workers have to computing will vary. Providing training and support to such end-users becomes a complex problem. In addition, based on their prior exposure to computer technology in their work place individuals will have different experiences that make implementation of such systems more complex. Individual …

An Assessment Of The Nutrient Content Of Meals Provided And Facilities Present At State-Funded Crèches In Cape Town, C Pietersen, K E. Charlton, M C. Du Toit, L Sibeko

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

Background: A large proportion of resources allocated to the Community-Based Nutrition Programme (CBNP) of the Department of Health in the Western Cape is spent on crèche-feeding schemes. To date, little evaluation of the CBNP has been undertaken. Aim: A cross-sectional study was conducted to assess the nutritional adequacy of meals provided, and facilities available, at state-funded crèches in the Cape Metropole. Methods: A questionnaire was administered to managers of 43 conveniently sampled crèches in two districts of Cape Town. Twenty-two of the crèches were randomly selected for nutrient assessment of a duplicate meal, and a typical meal sample was weighed …
