It starts with the parents and ends with the parents

Alcohol is the most popular recreational drug in Australia. Despite the fact that many people gain enjoyment from alcohol related industries, alcohol is also implicated in much personal trauma and social damage. Parents play a key role in influencing alcohol use and driver behaviour in young people. The aim of this study was to gain an understanding of the attitudes and concerns of parents in Melbourne in relation to their teenage children's use of alcohol and how they educate and/or provide role models for their adolescents with respect to alcohol usage. A convenience sample of parents with adolescent children participated in focus groups. Parents described patterns of alcohol use and perceived influences on consumption. They reported that they wanted to create safe environments for adolescents to consume alcohol but that they needed more support and information on which to base these decisions. There i, an opportunity for public health policy makers to specifically address parents and enhance their role in alcohol related road safety.

Beyond Simon’s means-ends analysis : natural creativity and the unanswered ‘why’ in the design of intelligent systems for problem-solving

Goal-directed problem solving as originally advocated by Herbert Simon’s means-ends analysis model has primarily shaped the course of design research on artificially intelligent systems for problem-solving. We contend that there is a definite disregard of a key phase within the overall design process that in fact logically precedes the actual problem solving phase. While systems designers have traditionally been obsessed with goal-directed problem solving, the basic determinants of the ultimate desired goal state still remain to be fully understood or categorically defined. We propose a rational framework built on a set of logically interconnected conjectures to specifically recognize this neglected phase in the overall design process of intelligent systems for practical problem-solving applications.

"Roll Up and Spend Your Last Dime". The Merry-go-round of Children`s Extra-curricular Activities in Modern Society.

"Step up and play" begins the famous hit song 'Penny Arcade'. And so it
was for thousands of Australian families, as their eldest child began school
this year, and the associated endless merry-go-round of extra-curricular
activities also began. But how many of those families realise that the song ends "Roll up and spend your last dime!"? While the perceived benefits of
children's involvement in extracurricular activities are many and are widely accepted, there are also costs, not only in terms of money but also in terms
of time. Evidence from a study conducted in Melbourne highlights the fact that, for many families such as those on low incomes and those headed by a single parent, both the time and the money costs may be prohibitive. This article highlights parents' perceptions of the benefits·and costs of children's extra-curricular activities, and explores the implications of changing family and household structures for families' capacity to sustain such activities.

Mill specific prediction of worsted yarn performance

Different spinning mills use different raw materials, processing methodologies, and equipment, all of which influence the quality of the yarns produced. Because of many variables, there is a difficulty in developing a universal empirical/theoretical model. This work presents a multilayer perceptron algorithm (MLP) model for the purpose of building a mill specific worsted spinning performance prediction tool. Sixteen inputs are used to predict key yarn properties and spinning performance, including number of fibers in cross-section, unevenness (U%), thin places, neps, yarn tenacity, elongation at break, thick places, and spinning ends-down. Validation of the model on mill specific commercial data set shows that the general fit to the target values is good. Importantly, the performance of the MLP shows a certain degree of stability to different, random selections of independent test data. Subsequent comparison against the predicted outputs of Sirolan Yarnspec™ confirms the overall performance of the artificial neural network (ANN) method to be more accuratefor mill specific predictions.

The effect of yarn hairiness on air drag in ring spinning

Air drag on yarn and package surfaces affects yarn tension, which in turn affects energy consumption and ends-down in ring spinning. This study investigated the effects of yarn hairiness on air drag in ring spinning. Theoretical models of skin friction coefficient on the surface of rotating yarn packages were developed. The predicted results were verified with experimental data obtained from cotton and wool yarns. The results show that hairiness increases the air drag by about one-quarter and one-third for the rotating cotton and wool yarn packages, respectively. In addition, yarn hairiness increases the air drag by about one-tenth on a ballooning cotton yarn.

Western maps/Yanyuwa meaning: an interview with John Bradley

In July 2003 an important one-volume text, Forget about Flinders: A Yanyuwa atlas of the south west gulf of Carpentaria produced in a limited edition of 14 copies, returned to Yanyuwa country and to the families who collaborated with John Bradley and artist Nona Cameron on the project. Subsequently, a second edition of 20 copies has been released, mainly to institutions. It is the most comprehensive attempt yet to restore Yanyuwa names to country and to produce a multilayered, dynamic, history-rich, and bilingual representation of how country is known in this community, and how the central song cycle texts intersect with Yanyuwa tradition. What follows is a condensed and edited interview with Frances Devlin-Glass, in which John Bradley discusses the motivations, the hybridised methodologies employed, the innovations of this new genre, and the pedagogical ends served by this latest iteration of Yanyuwa song cycles.

Is life dissatisfaction the opposite of life satisfaction?

The circumplex model of affect proposes that states of affect can be categorised according to the two dimensions of valence and arousal. According to this model, satisfaction and dissatisfaction are located on the pleasant and unpleasant ends of the valence axis as bipolar opposites. This study investigated the relationship between these two adjectives when assessed with unipolar or bipolar response formats. This suggests that a reciprocal relationship exists between life satisfaction and dissatisfaction when a unipolar response format is employed, but not when a bipolar response format was used. These results are discussed in relation to current affect theory and subject wellbeing research.

How world's best public relations practice was not, but might have been achieved, in respect of a "biosolids" (stabilised sewage sludge) project

This is a case study which criticises the way a water authority has been trying to introduce “biosolids” (stabilised sewage sludge) projects. Two proposed projects have been abandoned after outcry by communities neighbouring earmarked sites. At the time of writing a third project was going ahead. This local scale clash reflects contests which are cropping up globally as water authorities are restricted in their use of land or sea dumping and ordered to introduce environmentally sustainable practices. The case study ends with a discussion of a strand of cultural theory which might have given the water authority a better understanding of the public issues involved. The article concludes that understanding cultural theory might assist organisations achieve world best practice in public relations when they face some of the pressing environmental and safety concerns of the 21st century.

Towards institution-wide online teaching and learning systems: trends, drivers and issues

Universities worldwide are consolidating and enhancing their commitments to various models of e-learning. These activities are leading to the adoption of corporate-wide e-learning systems, and accompanying changes in structures, processes and infrastructure requirements. The professed ideal is to identify narrowly defined corporate IT solutions which can deliver the full range of educational, administrative and student support features to meet the organisational need to expand e-learning activities globally. The trend seems to be away from locally driven and controlled IT development and adoption towards investments in Instructional Management Systems (IMS). In reality, however, universities generally are developing and using a broader array of solutions to meet their needs than may be deemed desirable under a more centralised, corporatised IT approach. This paper examines these trends by analysing the drivers shaping corporate approaches to IT implementation, and reflects critically on some of the educational, economic and organisational tensions and issues evident in institutional approaches to establishing such systems. The paper highlights the ongoing need for innovative, dynamic organisational solutions to progress the e-learning agenda, and the thoughtful reconciliation of centralised and decentralised approaches to achieving desired ends.
