Polygraph testing for deception in Australia: effective aid to crime investigation and adjudication?

Polygraph testing--or the monitoring and analysing of selected physiological measures of an individual who is being interviewed, for the purpose of detecting deception--is controversial in Australia. Considerable mythology surrounds this method of detecting deception. Embedded in popular perceptions of crime fighting and utilised in high-profile criminal cases in Western Australia, Victoria and Queensland, polygraph testing is also explicitly prohibited from being used in crime investigation in New South Wales. Unlike in the United States, polygraph testing has not hitherto routinely been used by government departments and authorities as a preemployment screening tool, but is increasingly being offered in the private sector in Australia. This article examines the current scope of polygraph testing in Australia, describes different approaches to testing, briefly reviews recent information relating to validity and evaluates State legislation prohibiting the use of polygraph testing for specified purposes in New South Wales. Consequent to the continuing controversy regarding the accuracy of polygraph testing in detecting deception (and, conversely, truth-telling), it is argued that the emerging use of polygraph testing is problematic and common law principles rendering the results of such testing inadmissible in court do not constitute sufficient safeguard against inappropriate and intrusive testing. Future research should identify specific polygraph testing techniques and consider the most socially beneficial way of regulating this emerging area of practice.     

The elderly's access to health care services: The crude and subtle impacts of Medicare changes

Medicare, the federal government's health insurance program for the aged and disabled, has been subjected to a number of legislative and regulatory changes since 1981 aimed at reducing the costs of the program. About a third of the cutbacks have been in activities that directly increase patient cost sharing. Other changes, while aimed at improving efficiency, may also shift costs onto program beneficiaries. This paper estimates the differential impacts of such program changes by age and income of elderly Medicare enrollees and discusses the likely resulting impact on their access to care. Surprisingly, such equity concerns have been largely overlooked in the policy debate concerning cost containment under Medicare.     

Education and identity: Thoughts on the social origins of anorexia

Anorexia nervosa is often said to be a condition which afflicts mainly middle-class girls. This paper suggests that it is not social class but a high level of educational attainment which is associated with the onset of anorexia.The effect of education is analysed in terms of it's influence on the identity -formation of the young woman. Anorexia can be seen as an attempt to rescue a spoilt identity.     

U.S. Child Safety Seat Laws: Are they Effective,and Who Complies?

This paper assesses the effectiveness of child safety seat laws in the United States. Over the past 35 years, these laws have steadily increased mandatory child safety seat restraint ages. We exploit state‐year level variation in the age until which children are required to ride in child safety seats to estimate triple difference models using Fatality Analysis Reporting System (FARS) data from 1975 to 2011. Our findings show that increasing the age thresholds is effective in increasing the actual age of children in safety seats. Across the child‐age distribution, restraint rates increase by between 10 and 30 percentage points or by between 50 and 170 percent, in the long run. We also estimate the impact of the child safety seat laws on the likelihood that a child dies in a fatal accident. We find that the laws saved up to 39 children per year. Finally, we find that the laws primarily induce compliant parents to switch from traditional seatbelt use to child safety seat use, with only small effects among parents who do not restrain their children.
