Have You Heard? The Role Of Rumour During Organisational Change Processes, Elizabeth Heathcote, Shane Dawson
Have You Heard? The Role Of Rumour During Organisational Change Processes, Elizabeth Heathcote, Shane Dawson
Faculty of Science, Medicine and Health - Papers: part A
This paper discusses the results of a study of communication and rumour among frontline staff during an arganisational change at a large Australian metropolitan university, and relates the findings to the literature and research surrounding rumour during organisational changes. Secondly, it describes the measures undertaken in a second organisational change, as a result of these lessons learned, to minimise the amount of rumour circulating and address their basic content.

In recent research the change-detection paradigm has been used along with cueing manipulations to show that more attention is allocated to the upper than lower facial region, and that this attentional allocation is disrupted by inversion. We report two experiments the object of which was to investigate how the type of information changed might be a factor in these findings by explicitly comparing the role of attention in detecting change to information thought to be special to faces (second-order relations) with information that is more useful for basic-level object discrimination (first-order relations). Results suggest that attention is automatically directed to …

Although traditionally there has been a debate over whether object recognition involves 3-D structural descriptions or 2-D views, most current approaches to object recognition include the representation of object structure in some form. An advantage for the processing of structural or configural information in objects has been recently demonstrated using a change detection task (Keane, Hayward, & Burke, 2003). We report two experiments that extend this finding and show that configural information dominates change detection performance regardless of an object's orientation. Experiment 1 demonstrated the advantage that configural information has over shape and part arrangement information in change detection across …
What Can Change Blindness Tell Us About The Visual Processing Of Complex Objects?, Simone Keane, Stephen A. Palmisano
What Can Change Blindness Tell Us About The Visual Processing Of Complex Objects?, Simone Keane, Stephen A. Palmisano
Faculty of Health and Behavioural Sciences - Papers (Archive)
Processing visual information about objects in our environment is an essential and widely used skill. However, recent research in change blindness suggests that humans are remarkably poor at detecting certain types of changes to objects. In particular, changes to the configuration of an object's parts are detected quicker and more accurately than changes to the shape of the parts or a switching of parts. The implication of this finding is that information regarding the layout or configuration of an object is better encoded than finer details, like part shape. The aim of the current study was to determine whether this …
Physical Activity, Change In Blood Pressure And Predictors Of Mortality In Older South Africans - A 2-Year Follow-Up Study, Karen E. Charlton, Estelle V. Lambert, Judith Kreft
Physical Activity, Change In Blood Pressure And Predictors Of Mortality In Older South Africans - A 2-Year Follow-Up Study, Karen E. Charlton, Estelle V. Lambert, Judith Kreft
Faculty of Science, Medicine and Health - Papers: part A
Objective. A 2-year follow-up study of a cohort of 200 historically disadvantaged older South Africans was conducted to: (i) characterise current levels of habitual physical activity; (ii) relate physical activity to current risk factors for chronic disease; and (iii) identify risk factors associated with 2-year mortaJity. The baseline sample, drawn in 1993, was found to have a high prevalence of hypertension (71.7%). Research design. Retrospective cohort study. Methods. A baseline sample of 200 persons aged ;:;.. 65 years, resident in the Cape Peninsula, was randomly drawn by means of a two-stage cluster design. Baseline measurements included: anthropometry, waist/hip ratio, systolic …
