How Different Is Different? Investigating Criteria For Different Identity Judgments, Harold C. Hill, Michelle Corcoran, Peter Claes, John Clement
How Different Is Different? Investigating Criteria For Different Identity Judgments, Harold C. Hill, Michelle Corcoran, Peter Claes, John Clement

Any face seen for the first time will have a closet neighbour in memory. In order to avoid false alarms, we must be able to distinguish similar from identical faces. Work is reported investigating same/different judgments as a function difference in three dimensional shape defined in terms of standard deviation in a principal component based face space. The aim is to determine the criterion difference below which observers respond “same”. A threshold corresponding to a dprime of 1 was also calculated. Both were first measured under three conditions – same view images, different view images and animated images of the …

The role of Escherichia coli as a pathogen has been the focus of considerable study, while much less is known about it as a commensal and how it adapts to and colonizes different environmental niches within the mammalian gut. In this study, we characterize Escherichia coli organisms (n=146) isolated from different regions of the intestinal tracts of eight pigs (dueodenum, ileum, colon, and feces). The isolates were typed using the method of random amplified polymorphic DNA (RAPD) and screened for the presence of bacteriocin genes and plasmid replicon types. Molecular analysis of variance using the RAPD data showed that E. …

Introduction: Tumour-associated urokinase plasminogen activator (uPA) is a critical marker of invasion and metastasis, and it is recognised as having strong prognostic relevance as well as being a therapeutic target. The specific uPA inhibitor plasminogen activator inhibitor type-2 (PAI-2, SerpinB2) specifically targets cell bound uPA and is internalised. Furthermore, preclinical studies have established the “proof-of-principle” of uPA-targeting by PAI-2-cytotoxin conjugates in human carcinoma models. However, these studies also suggest that PAI-2 is rapidly cleared via the renal system with low total dose reaching the tumour. In this study, a comparative single photon emission computed tomography (SPECT) and biodistribution (BD) analysis …
Does Presentation Make A Difference To Risk Perception: Testing Different Formats For Communication Of Cancer Risks, Sandra C. Jones
Does Presentation Make A Difference To Risk Perception: Testing Different Formats For Communication Of Cancer Risks, Sandra C. Jones

Evidence suggests that the presentation format of risk information can affect people’s perceptions of risk and influence health-related decisions. In these studies we investigated the impact of four different risk presentation formats: standard presentation, risk ladder, different base rates and visual representations on women’s perceptions of developing breast cancer of lymphoma. We found that the different presentations had virtually no impact on the participant’s risk estimates. Only in the second study relating to risk perceptions for lymphoma was there a significant difference between conditions for estimated 10-year-risk, with those in the ladder present condition reporting a lower estimated risk. The …

Changes to ecosystem abiotic parameters are regarded as possible mechanisms facilitating plant invasion and community composition shifts. This study compared the hydrophobic chemical signatures of soil from exotic bitou bush (Chrysanthemoides monilifera spp. rotundata) invaded, indigenous acacia (Acacia longifolia var. sophorae) dominated and bare sand (unvegetated) habitats using a novel, rapid, capturing technique which utilised AmberliteA (R) XAD4 resin filled bags that were placed in situ. The hydrophobic chemical signature of the bitou bush soil extract was significantly different to the acacia soil and bare sand extracts. High concentrations of 18 sesquiterpenes dominated the hydrophobic signature of the bitou bush …

Lipid model membranes such as 1,2-Dimyristoyl-sn-Glycero-3-Phosphocholine (DMPC) serve as role models for their more complex counterparts in biological systems. Quasielastic neutron scattering (QENS) [1-3], inelastic neutron scattering (INS) [4] and neutron spin echo spectroscopy (NSE) [5] have been employed to study local as well as collective dynamics of these membranes on a ps-ns time scale. Most of these studies lack a systematic investigation of the behavior of the model membranes in dependence on their hydration. We now started a detailed investigation of hydration effect on model membrane systems. The complexity of the dynamics can be further reduced by selective deuteration, …
The Utility Of Different Object Properties In Change Detection, Simone K. Favelle, Stephen A. Palmisano
The Utility Of Different Object Properties In Change Detection, Simone K. Favelle, Stephen A. Palmisano

Previous research has shown that changes to the configuration of an object's parts are better detected than changes to the shape/arrangement of those parts. This finding suggests that configural, rather than shape, information plays a critical role in object change detection. The current study investigated configural and shape changes in greater detail to determine what aspects of these two types of object properties, if any, were more or less important for change detection. Specifically we investigated configural changes in terms of the orientation of the part change and shape changes in terms of the non-accidental properties of the part change. …

The impact of an exotic species in natural systems may be dependent not only on invader attributes but also on characteristics of the invaded community. We examined impacts of the invader bitou bush, Chrysanthemoides monilifera ssp. rotundata , in fore and hind dune communities of coastal New South Wales, Australia. We compared invader impacts on vegetation structure, richness of both native and exotic growth forms and community variability in fore and hind dunes. We found that impacts of bitou invasion were context specific: in fore dune shrublands, functionally distinct graminoid, herb and climber rather than shrub growth forms had significantly …

Four groups of young pigs (n 6) were fed a diet containing 50 % maize starch as either a highly digestible waxy starch (control; 0 % amylose) or one of three resistant starch (RS) diets, namely a high-amylose maize starch (HAMS; 85 % amylose), this starch subjected to hydrothermal treatment (HTHAMS; 85 % amylose), or a blend of HAMS and HTHAMS included in equal amounts, for 21 d. Food intake and live weight at the end of the study were similar among the four groups. Ileal starch digestibility was lower in pigs fed the three RS diets but was …

Objective: The aim of this study was to model children’s potential exposure to television food advertisements under different regulatory scenarios to demonstrate the policy implications of regulatory change in Australia. Methods: Television advertising data was collected from Sydney commercial television channels from 14-20 May 2006. Extrapolating from these data, the patterns of food advertising under four regulatory scenarios were examined, including arrangements restricting the content, volume and timing of advertisements. Results: Each scenario resulted in a reduction of total and non-core food advertisements. The scenario to restrict non-core food advertisements during the major viewing period (7:00-20:30) led to the largest …
