Word Association Tests Of Associative Memory And Implicit Processes: Theoretical And Assessment Issues, Alan W. Stacy, Susan L. Ames, Jerry L. Grenard

CGU Faculty Publications and Research

Word association is one of the most commonly used measures of association in cognitive science. These tests have been used to infer association parameters in normative studies, to derive cues and primes used in diverse paradigms (semantic priming, cued recall, illusory memory), to test implicit memory in experimental studies, and to suggest the operation of implicit processes in nonexperimental work. This chapter briefly outlines some of the historical routes and current controversies about association and summarizes basic cognitive research applying associative tests. The authors then describe benefits and limitations of the tests, as well as implications for theory and interventions …

Does Food Stamp Receipt Mediate The Relationship Between Food Insufficiency And Mental Health?, Colleen Heflin, James P. Ziliak

University of Kentucky Center for Poverty Research Discussion Paper Series

Although the Food Stamp Program is the largest entitlement program remaining in the social safety net, comparatively little is known about the potential benefits that the program may confer on recipients. In this paper we examine an important dimension of well being, mental health, and the extent to which participation in the Food Stamp Program may attenuate the effect of food insufficiency on levels of emotional distress. Using longitudinal data from a nationally representative sample of families in the Panel Study of Income Dynamics (PSID) we model emotional distress as a function of food insufficiency and other known risk factors …

Piezoresistive Sensors On Textiles By Inkjet Printing And Electroless Plating, Amit Sawhney, Animesh Agrawal, Prabir Patra, Paul Calvert

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

We have printed arrays of strain sensors on textiles by inkjet printing of conducting lines and piezoresistive polymer (PEDOT) in order to provide detailed information about the response of a fabric in use. Conducting polymer has been printed onto polyamide and cellulose woven fabrics to form sensors using a modified HP inkjet print-head and X-Y linear positioning table. Good penetration and attachment is found on mercerized cotton but not on polyamide. Silver nitrate lines have been printed onto polyamide and converted to silver connectors by electroless plating. We observed that resistance of silver lines ranged from 0.7-1.5Ω/cm whereas for the …

Differentiation Of Bone Marrow Stem Cells On Inkjet Printed Silk Lines, Skander Limem, Paul Calvert, Hyeon Joo Kim, David L. Kaplan

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

Water based silk solutions were successfully inkjet printed for the first time into patterns of parallel lines onto vinyl plastic substrates. Human bone marrow stromal cells (hMSCs) were seeded on the silk printed patterns and cultured in the presence of 100 ng/ml of bone morphogenic protein (BMP-2). After one week of culture cell growth and attachment showed site specificity on the silk printed lines. Both alkaline phosphatase activity and cell morphology indicated hBMSCs differentiation into osteogenic cells along the silk printed lines. After 4 week of culture, the cellular bridging of adjacent silk printed lines took place for all interline …

Structure Of The Theta Subunit Of Escherichia Coli Dna Polymerase Iii In Complex With The Epsilon Subunit, Max A Keniry, Ah-Young Park, Elisabeth A. Owen, Samir M. Hamdan, Guido Pintacuda, Gottfried Otting, Nicholas E. Dixon

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

The catalytic core of Escherichia coli DNA polymerase III contains three tightly associated subunits, the α, ε, and θ subunits. The θ subunit is the smallest and least understood subunit. The three-dimensional structure of θ in a complex with the unlabeled N-terminal domain of the ε subunit, ε186, was determined by multidimensional nuclear magnetic resonance spectroscopy. The structure was refined using pseudocontact shifts that resulted from inserting a lanthanide ion (Dy³⁺, Er³⁺, or Ho³⁺) at the active site of ε186. The structure determination revealed a three-helix bundle fold that is similar to the solution …

Ling, A New Integron-Associated Gene Cassette Encoding A Lincosamide Nucleotidyltransferase, Renee S. Levings, Ruth M. Hall, Diane Lightfoot, Steven P. Djordjevic

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

Lincosamide antibiotics include lincomycin, a compound produced by several actinomycetes, and its semisynthetic chlorinated derivative clindamycin. These antibiotics block the peptidyltransferase activity of the 50S subunit of the bacterial ribosome, inhibiting protein synthesis, and are active against most gram-positive cocci and anaerobes. However, they are not generally effective against gram-negative bacilli due to intrinsic resistance.

The Impact Of Institutional Surveillance Technologies On Student Behaviour, Shane Dawson

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

Contemporary education institutions are increasingly investing fiscal and human resources to further develop their online infrastructure in order to enhance flexible learning options and the overall student learning experience. Coinciding with the implementation of these technologies has been the centralisation of data and the emergence of online activities that have afforded the capacity for more intimate modes of surveillance by both the institution and education practitioner. This study offers an initial investigation into the impact of such modes of surveillance on student behaviours. Both internal and external students surveyed indicated that their browsing behaviours, the range of topics discussed and …

Observation Of Nondegenerate Cavity Modes For A Distorted Cavity Modes For A Distorted Polystyrene Microsphere, Adam J. Trevitt, Philip J. Wearne, Evan J. Bieske, Michael D. Schuder

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

Nondegenerate azimuthal morphology-dependent resonances are observed for a distorted, fluorescently labeled polystyrene microsphere levitated in a quadrupole ion trap. Modeling the individual resonances by using perturbation theory allows a determination of quadrupole and octupole distortion parameters. The particle’s shape changes slowly over the course of the measurement and eventually becomes spherical. The morphological changes are facilitated by laser heating of the particle above the polystyrene glass transition temperature. We demonstrate a method of transforming a trapped particle to a sphere and rendering its azimuthal modes degenerate.

Tracing The Geographic Origin Of The Cosmopolitan Parthenogenetic Insect Pest Liposcelis Bostrychophila (Psocoptera: Liposcelididae), K M. Mikac, G M. Clarke

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

The randomly amplified polymorphic DNA technique was used to trace the geographic origin of Liposcelis bostrychophila Badonnel populations in Australia from unknown geographic sources internationally. Haplotype (or clonal) diversity was high, with 474 unique haplotypes found from 616 individuals genotyped. Gene diversity estimates (0.10–0.28) and percent polymorphic loci (38.1–88.1%) were moderate to high for most populations. This resulted in genetic distance estimates that ranged from 0.04 to 0.26 and were significantly different for most pairwise population combinations. G ST values for all populations were also moderate (0.04–0.54) and again were significantly different for most pairwise population comparisons. Analysis of molecular …

Surface Process Models And The Links Between Tectonics And Topography, Alexandru T. Codilean, Paul Bishop, Trevor B. Hoey

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

Advances in the theoretical understanding of large-scale tectonic and surface processes, along with a rapid growth of computing technology, have stimulated interest in the use of numerical surface process models (SPMs) of long-term landscape evolution, especially in relation to the links between tectonics and topography. Because of these advances and possibilities and because SPMs continue to play an important part in recent geological, geomorphological, thermochronological and other geosciences research, the models warrant review and assessment. This review summarizes and evaluates the important issues concerning SPMs of long-term landscape evolution that have been addressed only in a passing way by previous …

Nosocomial And Community Transmission Of Measles Virus Genotype D8 Imported By A Returning Traveller From Nepal, Kathryn M. Weston, Dominic Dwyer, Mala Ratnamohan, Kenneth Mcphie, Sau-Wan Chan, James Branley, Lisa Allchin, Krishna Hort

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

Measles is uncommon in Australia due to effective national vaccination strategies. In mid-2003, a cluster of nine cases of measles occurred in western Sydney. The index case was a 29-year-old traveller recently returned from Nepal. The case presented to hospital and transmitted the disease to two others in the Emergency Department. Further cases resulted from both community and nosocomial transmission. The median age of cases was 24 years, with three cases in children aged under four years. Only one person had a documented history of measles vaccination, a child who had received one dose of vaccine overseas. One case was …

Beyond The Rhetoric: What Do We Mean By A 'Model Of Care'?, Patricia Davidson, Elizabeth Halcomb, L Hickman, J Phillips, B Graham

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

Background: Contemporary health care systems are constantly challenged to revise traditional methods of health care delivery. These challenges are multifaceted and stem from: (1) novel pharmacological and non-pharmacological treatments; (2) changes in consumer demands and expectations; (3) fiscal and resource constraints; (4) changes in societal demographics in particular the ageing of society; (5) an increasing burden of chronic disease; (6) documentation of limitations in traditional health care delivery; (7) increased emphasis on transparency, accountability, evidence-based practice (EBP) and clinical governance structures; and (8) the increasing cultural diversity of the community. These challenges provoke discussion of potential alternative models of care, …

Recovery And Evolutionary Analysis Of Complete Integron Gene Cassette Arrays From Vibrio, Yan Boucher, Camilla L. Nesbo, Michael J. Joss, Andrew Robinson, Bridget C. Mabbutt, Michael R. Gillings, W Ford Doolittle, Hatch W. Stokes

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

Background: Integrons are genetic elements capable of the acquisition, rearrangement and expression of genes contained in gene cassettes. Gene cassettes generally consist of a promoterless gene associated with a recombination site known as a 59-base element (59-be). Multiple insertion events can lead to the assembly of large integron-associated cassette arrays. The most striking examples are found in Vibrio, where such cassette arrays are widespread and can range from 30 kb to 150 kb. Besides those found in completely sequenced genomes, no such array has yet been recovered in its entirety. We describe an approach to systematically isolate, sequence and annotate …

A Method For Improving Landscape Scale Temperature Predictions And The Implications For Vegetation Modelling, Michael B. Ashcroft

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

Understanding how environmental factors influence the spatial distribution of vegetation allows environmental managers to plan for issues such as climate change, ecological restoration and intensified land use. Elevation is often used as an indirect predictor of temperature, but this limits the applicability of environmental models to other study areas and introduces errors in mountainous terrain where variations in slope, aspect, and radiation can significantly alter the relationship between elevation and temperature. Some studies have developed estimates for temperature that also consider factors such as radiation, but these usually estimate the temperature for each location without considering the surrounding environment. In …

Homework has been suggested as being an important clinical adjunct to case management practices, however, to date, research has not examined case managers’ use of homework. Aims: To identify the degree that case managers use homework within their clinical practice and explore the way it is administered with people diagnosed with a persistent and recurring psychiatric illness. Method: A survey was completed by 122 case managers (63% of those approached) comprising nurses, psychologists, social workers, occupational therapists and welfare/support workers. Results: Ninety-three percent of case managers implement homework, …

Infants' Discrimination Of Faces By Using Biological Motion Cues, Janine Spencer, Justin O'Brien, Alan Johnston, Harold C. Hill

Faculty of Health and Behavioural Sciences - Papers (Archive)

We report two experiments in which we used animated averaged faces to examine infants' ability to perceive and discriminate facial motion. The faces were generated by using the motion recorded from the faces of volunteers while they spoke. We tested infants aged 4 ^ 8 months to assess their ability to discriminate facial motion sequences (condition 1) and discrim- inate the faces of individuals (condition 2). Infants were habituated to one sequence with the motion of one actor speaking one phrase. Following habituation, infants were presented with the same sequence together with motion from a different actor (condition 1), or …

Visual Correlates Of Prosodic Contrastive Focus In French: Description And Inter-Speaker Variability, Marion Dohen, Helene Loevenbruck, Harold C. Hill

Faculty of Health and Behavioural Sciences - Papers (Archive)

This study is a follow-up of previous studies we conducted on the visible articulatory correlates of French prosodic contrastive focus. A two speaker analysis using an automatic lip-tracking device had shown that these correlates existed and were used in visual perception. However the articulatory strategies depended on the speaker. The purpose of this study was thus to extend the analysis to other speakers, examine the similarities and variabilities and try to identify global tendencies. We recorded five speakers of French with a 3D optical tracker using a 13 sentence (subject-verb-object) corpus and four focus conditions (S, V, O or neutral). …

Effect Of Decorrelation On 3-D Grating Detection With Static And Dynamic Random-Dot Stereograms, Stephen A. Palmisano, Robert S. Allison, Ian P. Howard

Faculty of Health and Behavioural Sciences - Papers (Archive)

Three experiments examined the effects of image decorrelation on the stereoscopic detection of sinusoidal depth gratings in static anddynamic random-dot stereograms (RDS). Detection was found to tolerate greater levels of image decorrelation as: (i) density increasedfrom 23 to 676 dots/deg2; (ii) spatial frequency decreased from 0.88 to 0.22 cpd; (iii) amplitude increased above 0.5 arcmin; and (iv) dotlifetime decreased from 1.6 s (static RDS) to 80 ms (dynamic RDS). In each case, the specific pattern of tolerance to decorrelation couldbe explained by its consequences for image sampling, filtering, and the influence of depth noise.

Challenges To Temperature Regulation When Working In Hot Environments, Nigel Taylor

Faculty of Health and Behavioural Sciences - Papers (Archive)

The focus of this revuew us upon acute exposure to hot environments and the accompanying physiological changes. The target audience includes physiologists, physicians and occupational health and safety practioners. Using the principles of thermodynamics, the avenues for human heat exchange and explored, leading to an evaluation of some methods used to assess thermally-stressful environments. In particular, there is a critique of the wet-bulb globe temperature (WBGT) index, and an overview of an alternative means by which such assessments may be undertaken (the heat stress index). These principles and methods are combined to illustrate how one may evaluate the risk of …

Scaling Of Na+, K+-Atpase Molecular Activity And Membrane Fatty Acid Composition In Mammalian And Avian Hearts, Anthony J. Hulbert, Paul Else, Kurt Haga, Nigel Turner

Faculty of Health and Behavioural Sciences - Papers (Archive)

We have examined Na⁺,K⁺‐ATPase molecular activity and membrane fatty acid composition in the heart of six mammalian and eight avian species ranging in size from 30 g in mice to 280 kg in cattle and 13 g in zebra finches to 35 kg in emus, respectively. Na⁺,K⁺‐ATPase activity scaled negatively with body mass in both mammals and birds. In small mammals, the elevated enzyme activity was related to allometric changes in both the concentration and molecular activity (turnover rate) of Na⁺,K⁺‐ATPase enzymes, while in small birds, higher Na …

Illusory Scene Distortion Occurs During Perceived Self-Rotation In Roll, Stephen A. Palmisano, Ian P. Howard, Robert S. Allison

Faculty of Health and Behavioural Sciences - Papers (Archive)

We report a novel illusory distortion of the visual scene, which became apparent during both: (i) observer rotation inside a furnishedstationary room; and (ii) room rotation about the stationary observer. While this distortion had several manifestations, the most commonexperience was that scenery near Wxation appeared to sometimes lead and other times lag more peripheral scenery. Across a series ofexperiments, we eliminated explanations based on eye-movements, distance misperception, peripheral aliasing, diVerential motion sensitivityand adaptation. We found that these illusory scene distortions occurred only when the observer perceived (real or illusory) changesin self-tilt and maintained a stable Wxation.

Motivation, Psychological Distress And Exercise Adherence Following Myocardial Infarction, Angela Ljubic, Frank P. Deane, Robert Zecchin, Richard Denniss

Faculty of Health and Behavioural Sciences - Papers (Archive)

Fifty patients with myocardial infarction were recruited from a hospital based Cardiac Education and Assessment Program (CEAP) in Sydney, Australia. The Exercise Motivation Inventory-2 (EMI-2) and the Depression, Anxiety and Stress Scale (DASS) were administered prior to commencement in the program and re-administered by telephone interview at 5-month followup. Four exercise adherence measures were completed: attendance, exercise stress test, self-report ratings and a 7-day activity recall interview. There was a 46% adherence rate for MI patients during the hospital based CEAP. Of those individuals who completed CEAP, 91% obtained functional improvement on the exercise stress test. For the 38 patients …
