The quality of groundwaters in the central wheatbelt of W.A

IN south-western Australia permanent rivers are virtually absent and the larger drainage systems such as the Swan-Avon, Murray and Blackwood, which have their headwaters in inland low rainfall areas, are generally saline

How inferred contagion biases dispositional judgments of others

AbstractDrawing on recent evidence suggesting that beliefs about contagion underlie the market for celebrity-contaminated objects, the current work investigates how people can make biased dispositional judgments about consumers who own such objects. Results from four experiments indicate that when a consumer comes in contact with a celebrity-contaminated object and behaves in a manner that is inconsistent with the traits associated with that celebrity, people tend to make more extreme judgments of them. For instance, if the celebrity excels at a particular task, but the target who has come into contact with the celebrity-contaminated object performs poorly, people reflect more harshly on the target. This occurs because observers implicitly expect that a consumer will behave in a way that is consistent with the traits associated with the source of contamination. Consistent with the law of contagion, these expectations only emerge when contact occurs. Our findings suggest that owning celebrity-contaminated objects signals information about how one might behave in the future, which consequently has social implications for consumers who own such objects

The type numbers of closed geodesics

Symplectically degenerate maxima via generating functions

We provide a simple proof of a theorem due to Nancy Hingston, asserting that symplectically degenerate maxima of any Hamiltonian diffeomorphism of the standard symplectic 2d-torus are non-isolated contractible periodic points or their action is a non-isolated point of the average-action spectrum. Our argument is based on generating functions.Comment: 25 pages, thoroughly revised version, new titl

Do you see what I see? Identification of child protection concerns by hospital staff and general dental practitioners

Aim An exploration of the threshold that dentists, doctors and nurses recognise for dental and child protection (CP) actions in sample clinical cases, and any differences between these professional groups. Method We present a cross-sectional survey of dentists, doctors and nurses (50 each), who regularly examine children, utilised five fictitious vignettes, combining an oral examination image and clinical history reflecting dental and CP issues. Demographics were collected, and each participant gave their likely action for the cases presented. Results Dentists were significantly better at answering the dental element than the doctors and nurses, (P <0.0001) with no significant difference between these two; only 8% of the latter had undergone any training in assessment of dental health. Although 90.6% of all professionals had undergone CP training, dentists were significantly less accurate at identifying the CP component than doctors and nurses, (P <0.0001) between whom there were no significant differences. Those with higher levels of CP training were most accurate at identifying correct CP actions. Conclusions CP training is effective at improving recognition of child maltreatment, although there remains a worrying lack of knowledge about thresholds for action among dentists. Doctors and nurses have minimal training in, or knowledge of, dental health in children, thus precluding appropriate onward referrals
