Comparison of the analytical capabilities of the BAC Datamaster and Datamaster DMT forensic breath testing devices

The State of Michigan uses the Datamaster as an evidential breath testing device. The newest version, the DMT, will replace current instruments in the field as they are retired from service. The Michigan State Police conducted comparison studies to test the analytical properties of the new instrument and to evaluate its response to conditions commonly cited in court defenses. The effects of mouth alcohol, objects in the mouth, and radiofrequency interference on paired samples from drinking subjects were assessed on the DMT. The effects of sample duration and chemical interferents were assessed on both instruments, using drinking subjects and wet-bath simulators, respectively. Our testing shows that Datamaster and DMT results are essentially identical; the DMT gave accurate readings as compared with measurements made using simulators containing standard ethanol solutions and that the DMT did not give falsely elevated breath alcohol results from any of the influences tested.     

Sampling and statistical considerations for the Suchey–Brooks method for pubic bone age estimation: Implications for regional comparisons

Although the Suchey–Brooks (SB) system is currently the most widely used method for age-at-death estimation from the pubic bone, the system continues to evolve through stepwise improvements. Since the system was developed from a pubic bone sample derived mainly from North Americans, it is unclear how well it performs on populations from other continents. During the last decade, studies of the SB system on pubic bone samples from local populations in Europe and Asia have indicated regional differences in the relationship between age and pubic bone development. However, these studies have for the most part followed different research protocols, which make comparisons between their results less meaningful. It would be most useful if future regional analysis of the SB system were done in a rigorous and uniform fashion, following standard procedures. In this paper, sampling and statistical considerations are outlined that hopefully will help to standardize research on the SB system.     

Religion und Religiosit?t als Ursache von Homonegativit?t

Although the attitudes towards homosexuality have become more liberal especially in industrialized Western countries, there is still a huge variance in terms of the levels of homonegativity worldwide. This article seeks to explain this variance by means of a multi-level-analysis of 79 countries. The data stem from the last two waves of the World Values Survey. On the basis of this data, the article focuses on the power of the religious denomination of a person and her religiousness in order to explain her attitude towards homosexuality; for both variables a strong influence can be detected. In addition, the article indicates that, on the individual level, socio-demographic variables??e.g. age, gender, education, marital status or profession??are highly interconnected with the intensity of homonegativity. On the country-level, however, the main explanatory factors are both the economic development and the communist heritage. The article further highlights significant conditional relationships by introducing cross-level interactions and interaction terms on the individual level. The final model explains about 60% of the variance on the aggregate level and 30% on the individual level.     

Centralisation versus regionalisation: Designing the Sixth National Mental Health Plan

In response to the recent Productivity Commission report into mental health, the previous Federal Government announced its intention to produce a new national agreement that lays the platform for Australia's sixth national mental health plan. It has been recommended mental health move to a more regional model of governance and planning, away from a centralised, top-down approach, partly in response to broader reforms affecting health care, and partly in direct response to consistent inquiry evidence that the mental health system remains in crisis. The past 30 years of mental health planning have been centralised. Successive national plans set a broad framework, with real decisions about mental health funding and service allocation made in the health departments of our capital cities. Will the next plan sponsor or inhibit regionality in mental health planning? This paper assesses Australia's historical approach to health planning particularly as it affected mental health and the costs arising. In learning these lessons, we propose the necessary ingredients to facilitate a regional, innovative, and effective approach to decentralised planning, for better mental health outcomes. We cannot afford to replicate the failed planning approaches of the past.
