Current trends in the rehabilitation of juvenile offenders

The Australian Institute of Criminology's recent work on adult male offenders has found that the most serious and persistent adult offenders had been detained as a juvenile. In terms of crime reduction, interventions that focus on reducing the likelihood of juveniles escalating to adult offenders will have significant benefits for the whole of the Australian community. Research conducted in juvenile justice settings around the world consistently shows that young people who come to the attention of criminal justice agencies have multiple problems and experience high levels of need across all areas of functioning. In meeting these needs, correctional agencies have been increasingly influenced by the model of rehabilitation known as the 'what works' approach. This paper outlines a case management framework for rehabilitating juvenile offenders that includes three of the most important 'what works' principles, namely the risk principle, the needs principle and the responsivity principle. In the longer term, the implementation of the framework will need to be evaluated to determine what works and what doesn't with rehabilitating juveniles.

Labour productivity trends in Australian manufacturing : some time series properties

Labour productivity plays a significant role in economic growth, labour demand and employment situation of a particular economy. In this light, the presence of a structural break in productivity, and its unit root property, has important consequences for the overall economy and in major sectors such as manufacturing. In this article, using some recently developed unit root tests, we examine: (i) the null hypothesis of a unit root in the log-level of labour productivity for 38 manufacturing subdivisions against the alternative of trend stationarity over a three-decade period; and (ii) the presence of a structural break in the series, and whether the break has had a permanent or a transitory effect on manufacturing labour productivity. Our main finding is that shocks to labour productivity have had a transitory effect, implying that policies are likely to have only short-term effects.

Modelling the linkages between the Australian and G7 stock markets : common stochastic trends and regime shifts

This paper examines whether the Australian equity market is integrated with the equity markets of the G7 economies by applying both the Johansen (Statistical analysis of conintegrating vectors, Journal of Economic Dynamics and Control, 12, 231-54, 1988) and Gregory and Hansen (Residual-based tests for cointegration in models with regime shifts, Journal of Econometrics, 70, 99-126, 1996) approaches to cointegration. Some evidence of a pairwise long-run relationship between the Australian stock market and the stock markets of Canada, Italy, Japan and the United Kingdom is found, but the Australian equity market is not pairwise cointegrated with the equity markets of France, Germany or the USA.

Cointegration of stock markets between New Zealand, Australia and the G7 Economies :searching for common trends under structural change

This paper examines whether the New Zealand equity market is integrated with the equity markets of Australia and the G7 economies by applying both the Johansen (1988) and Gregory and Hansen (1996) approaches to cointegration. The Johansen (1988) test suggests that there is no long-run relationship between the New Zealand stock market and any of the other stock markets considered in the study. The Gregory and Hansen (1996) test finds that the New Zealand and United States stock market is cointegrated, but the New Zealand stock market is not cointegrated with the other stock markets in the study. This suggests that in order to avoid some of the risk through international portfolio diversification there is potential for investors to purchase shares in the New Zealand market and either the Australian market or most of the world’s leading equity markets.

Trends in professional education programs for teachers

Increasingly, politicians, bureaucrats, the business community, members of our communities and even members of the teaching profession, are asking questions about professional preparation for teachers, questions like: What is the value of teacher education? What should beginning teachers know and be able to do? How can we make judgements about what they know and are able to do? How can teacher preparation contribute to the retention of high quality beginning teachers who continue to grow and learn?

In this paper, I examine these issues and examine how effective teacher preparation has attempted to respond to these issues, particularly in graduate teacher education programs. I argue that we need to be cognisant of the following aspects when developing and implementing high quality professional education of teachers:

• Connect teacher education to the first year of teaching;
• Prepare teachers who investigate their professional practice within communities of learners
• Prepare teachers with a strong professional knowledge base that helps them make informed professional judgments
• A cohort model that builds strong relationships and professional networks
• Early, regular and sustained school experiences that systematically build professional knowledge and skill. Closely monitored by suitably qualified university personnel and supervising teachers
• Professional standards for beginning teaching and a capstone teacher performance assessment

Computational investigations on periodic trends in Group 14 chemistry

Describes the use of computer-aided molecular modelling to investigate trends in the chemistry of the Group 14 elements, namely carbon, silicon, germanium, tin and lead. The chemical behaviour of two classes of molecules containing Group 14 elements was related to trends in the fundamental properties of these elements.

Physical trends and structural features in organic salts of the thiocyanate anion

A new series of ionic liquids based on the thiocyanate anion has been prepared. Incorporation of this anion with an imidazolium, tetraalkylammonium or pyrrolidinium cation produces ionic liquids with advantageously low melting points and good thermal stability. The low temperature phase behaviour of the salts has been investigated using differential scanning calorimetry and multiple solid phases have been observed. The electrochemical windows of representative imidazolium and pyrrolidinium species have been investigated by cyclic voltammetry and determined to be 2.4 and 3.5 V, respectively. In addition, the solid-state structure of N,N-dimethylpyrrolidinium thiocyanate has been determined by X-ray crystallography. This is the first reported structure of a pyrrolidinium thiocyanate species and shows a layered structure with linear thiocyanate groups having bond lengths comparable to those observed in similar SCN−-containing species.

Post-disaster fiction for young adults : some trends and variations

In the forty years or so since it began to develop as a sub-genre of young adult fiction, post-disaster fiction has commented on a range of issues, including perceived social fears of the time, the nature of various types of society, and what people need in order to be truly human. This paper explores how young adult post-disaster fiction makes comment on these and other issues. It argues that within this genre there are three connected sub-genres, with the disaster having a different function in each, and the nature of the comments made by each of these sub-genres tending also to be different. As its title suggests, this paper includes texts in which the focus is on life after the disaster. The genre’s strong link with both the nature of young adult fiction and with adolescence itself suggests that it will continue to flourish as a sub-genre.

Trends in food intake in French children from 1999 to 2007 : results from the INCA (étude Individuelle Nationale des Consommations Alimentaires) dietary surveys

The objectives of the present study were to assess the intake of different food groups in French children aged 3–17 years (n 1455), and to analyse trends since a dietary survey undertaken 8 years ago. Dietary intake was evaluated using data from the 2006–7 cross-sectional INCA2 national dietary survey (étude Individuelle Nationale sur les Consommations Alimentaires), based on a 7 d food record. Dietary intake (percentage of subjects consuming the food group and amount eaten) was assessed for thirty-nine food categories. We observed variations in food consumption by age, sex, North–South regional gradient, seasonal period and educational level of the responding parent. Trends in dietary intake between 1999 and 2007 were determined by comparing the INCA1 (n 1126) and the INCA2 surveys. Both surveys had been carried out using the same methodology. The findings showed a decrease in energy intake in children aged 3–14 years, due to a reduction in the consumption of foods of animal origin and sweetened products. In adolescents aged 15–17 years, energy intake remained rather stable; during this 8-year period, the consumption of meat decreased, whereas the consumption of savoury snacks such as sandwiches and hamburgers significantly increased. These trends occurred during a time of growing concern about overweight and the associated co-morbidities in France. A number of public health measures were implemented over this period to improve dietary habits and physical activity patterns in children and adults. The periodic monitoring of dietary patterns through the INCA surveys is an essential part of the surveillance network in France.
