In today's diverse society, health professionals require a complete understanding of how physiological, social and psychological factors impact physical wellbeing. Health Psychology in Australia provides a contemporary, relevant perspective on the unique climate in which this increasingly important area of healthcare is practised in Australia. Drawing on the expertise of the author team, this book gives students the skills to identify and evaluate health risk factors and to intervene in and manage health behaviour. Each chapter includes learning objectives, case studies with accompanying reflection questions, critical thinking activities and a detailed summary to consolidate learning. The comprehensive glossary and links to online resources solidify understanding of key concepts and ideas. Written with a focus on respectful advocacy of health promotion, Health Psychology in Australia provides psychology and allied health students with a comprehensive understanding of the role of the health psychologist as clinician, researcher, educator and client.
The surface composition of Mars has been investigated using the Thermal Emission Spectrometer (TES) instrument during the mapping phase of the Mars Global Surveyor mission. The TES has mapped ~85% of the Martian surface at a resolution of 3-9 km. Separation of the atmospheric dust, water-ice cloud, CO2, water vapor, and surface components has been accomplished using radiative transfer and deconvolution. Two distinct surface compositional units have been mapped; (1) a basalt with plagioclase feldspar, Ca-rich pyroxene, minor sheet silicates; and (2) a basaltic andesite with silica glass, plagioclase, and minor pyroxene. Three large-scale (100’s km) accumulations of hematite have been found in Sinus Meridiani, Aram Chaos and Ophir/Candor Chasms. These regions are interpreted to be formed by aqueous precipitation under either ambient or hydrothermal conditions. No surfaces with detectable abundances of carbonate have been found. The albedo of the surface has been mapped with an absolute accuracy of ~1-2% and significant changes in surface albedo have occurred from the orbital measurements obtained by the Viking IRTM instrument.
Can ordinary citizens in a democracy evaluate the claims of scientific experts? While a definitive answer must be case by case, some scholars have offered sharply opposed general answers: a skeptical “no” (e.g. Scott Brewer) versus an optimistic “yes, no problem” (e.g. Elizabeth Anderson). The article addresses this basic conflict, arguing that a satisfactory answer requires a first-order engagement in judging the claims of experts which both skeptics and optimists rule out in taking the issue to be one of second-order assessments only. Having argued that such first-order judgments are necessary, it then considers how they are possible, outlining a range of practices and virtues that can inform their success and likelihood, and drawing throughout on ancient Greek insights as well as contemporary social psychology and sociology of knowledge. In conclusion the ethics of democratic judgment so developed is applied to the dramatic conviction of the members of an Italian scientific risk commission in L'Aquila.
