This study examined 3 aspects of the male gender role and their relationship to alcohol and cannabis involvement in young adult Australian men (N = 160) aged between 18 and 25 years. Higher scores on the Restrictive Emotionality scale, which assessed gender ,role conflict, were found to relate to both alcohol-related problems and cannabis use. Higher scores on the Antifemininity scale, which assessed traditional attitudes toward men, were also found to be associated with alcohol-related problems. However, lower scores on another aspect of gender role conflict, Restrictive Affectionate Behavior Between Men, and lower scores on one aspect of traditional attitudes toward men, Status Rationality, correlated with higher frequency levels of alcohol and cannabis use.

Undergraduate students often have the misconception that molecules have fixed, unchanging bond lengths. This article discusses how linear-molecule rotational band spacings in infrared spectroscopy can be used as a qualitative, visual demonstration of the elongation of average bond lengths on vibrational excitation. The method does not depend on a detailed mathematical analysis of the spectra. In UV–vis spectroscopy, the rotational band spacings give rise to distinctive linear-molecule rotational contours, which easily show whether the average bond length has increased or decreased. The method is based on a spreadsheet simulation of the vibration–rotation or rovibronic (electronic–vibration–rotation) spectrum and is applied to hydrogen chloride IR, iodine UV–vis, and nitrogen UV–vis spectra in this article.

Exercise dependence (EXD) is a psychological condition associated with physical, emotional, social and performance consequences. Despite growing awareness of the prevalence of EXD within the athletic population, the symptoms or dimensions that comprise the condition largely remain unclear. The aim of the present study was to examine the perceptions of coaches relating to the symptoms or dimensions that define EXD among athletes. Participants were 90 coaches of elite athletes employed by the Australian Institute of Sport and State Institutes of Sport in Australia. Coaches completed an EXD checklist and a separate checklist of characteristics of committed exercisers. Both checklists contained 31 dimensions. The results supported a constellation of cognitive, emotional, behavioral, physical, social and performance dimensions. The results are discussed in terms of the consequences of EXD for elite athletes. Implications for coaches and teammates of elite athletes who experience EXD are also highlighted.

Using a high-frequency data set of the spot Australian dollar/US dollar this study examines the distribution of quotes and returns across the 24 hour trading "day". Employing statistical methods for measuring long-tenn dependence in time-series we find evidence of time-varying dependence and volatility that aligns with the opening and closing of markets. This variation is attributed to the effects of liquidity and the price-discovery actions of dealers.

The objective of this study was to investigate relationships between adolescent cannabis use and indices of parent - child attachment, family functioning and parent attitudes to drugs and delinquency. A total of 2848 year 9 and 2363 year 11 students participated in the Victorian Adolescent Health and Well-Being Survey (1999). The study was a school-based random sample of 535 metropolitan and rural, government and non-government secondary schools throughout Victoria, Australia. Cannabis use was defined as 'any' and 'weekly' use in the last 30 days. Multivariate logistic regression was used to identify independent associations between cannabis use and parent - child attachment, family functioning and parent attitudes to drugs and delinquency. Cannabis use in year 9 was associated with permissive parent attitudes to drugs and delinquency (any use: adjusted odds ratio (OR) = 8.1; weekly use: adjusted OR = 7.6), and was particularly sensitive to small changes in the quality of the parent - child relationship with risk increasing threefold for those describing their attachment as 'good' compared with 'very good' (any use: adjusted OR = 2.8, weekly use adjusted OR = 2.9). A similar, but more moderate pattern association was evident in year 11. After adjusting for other family and background factors, poor family functioning showed minimal association with level of cannabis use at both year levels. Results suggest that intervention efforts might sensibly target strengthening parent - children relationships and promoting less permissive parent attitudes to drug use.
