- Description: The high rates of depression and suicide among older adults have given rise to research which aims to identify factors that protect older people from mental illness. Recently, Bailey and McLaren (2005) developed and tested a model which investigated the relationships between engagement in various leisure activities performed alone or with others, sense of belonging, depression, and suicidal ideation. The present study examined an extended version of the mental health model, incorporating the additional variables of perceived freedom in leisure and physical health status. A sample of Australian males and females (N = 379) aged 65 years and over (M age = 77.23, SD = 7.48) completed the Perceived Freedom in Leisure Questionnaire, the Yale Physical Activity Survey,the Duke Health Profile, the Sense of Belonging Instrument, the Centre for Epidemiological Studies-Depressive Scale, and the Suicide Subscale of the General Health Questionnaire. Results indicated that the model was invariant for gender, and accounted for 56% of the variance in suicidal ideation. The model indicated that physical health had direct relationships with each variable in the model. Perceived freedom in leisure predicted engagement in physical activity, sense of belonging-antecedent, and depression, whereas sense of belonging psychological state predicted depression and suicidal ideation. Results suggest that interventions aimed at improving older adults’ perceptions of freedom and personal choice with regard to their leisure experiences, maintaining optimal health, and increasing opportunities to foster feelings of belonging and relatedness with others, should protect against the development of mental ill health.

- Description: Parthenium hysterophorus L. (Asteraceae) is a weed of national significance in Australia. Among the several arthropod agents introduced into Australia to control populations of P. hysterophorus biologically, Epiblema strenuana Walker (Lepidoptera: Tortricidae) is the most widespread and abundant agent. By intercepting the normal transport mechanisms of P. hysterophorus, the larvae of E. strenuana drain nutrients, other metabolic products, and energy, and place the host plant under intense metabolic stress. In this study, determinations of total non-structural carbohydrates (TNC) levels and carbon and nitrogen isotope ratios of fixed products in different parts of the plant tissue, including the gall, have been made to establish the function of gall as a sink for the nutrients Values of

- Description: Necessary and sufficient conditions for a local minimum form a well-developed chapter of optimization theory. Determination of such conditions for the global minimum is a challenging problem. Useful conditions are currently known only for a few classes of nonconvex optimization problems. It is important to find different classes of problems for which the required conditions can be obtained. In this paper we examine one of these classes: the minimization of the distance to an arbitrary closed set in a class of ordered normed spaces. We use the structure of the objective function in order to present necessary and sufficient conditions that give a clear understanding of the structure of a global minimizer and can be easily verified for some problems under consideration. © 2006 INFORMS.

- Description: Small-to-medium sized agribusiness enterprises (SMAEs) in developing countries have a complicated nature on co-joint business to create a high value of output. Most of the businesses tend to work individually, isolated and uncooperatively. They are not aware that if they do business cooperatively, this will create a higher value of output. Modern sophisticated Information and Communication Technology (ICT) in business can play an important role in enabling cooperation to flourish. In developed countries, ICT adoption in SMAEs has resulted in significant value addition to management improvement and output. In this paper, selected ICT adoption models from SMAEs in developed countries are studied as a benchmark for application to ASEAN developing countries. The aim of this paper is to demonstrate the importance of ICT in SMAEs as a linkage among the agribusiness sub-system in order to reduce both transaction and information cost. A proposed model is developed as an alternative approach for value creation of agribusiness in developing countries.

- Description: The catastrophic misinterpretation model [Behav. Res. Ther. 24 (1986) 461-470] proposes that panic attacks result from misinterpretation of interoceptive stimuli as precursors to physical or psychological emergency. Inconclusive evidence for the model may be partly explained by limitations of the questionnaires developed to measure catastrophic misinterpretation. For example, the Body Sensations Interpretation Questionnaire (BSIQ) is unable to clarify whether anxiety-related interpretations of ambiguous interoceptive stimuli represent catastrophic misinterpretations or responses masking feared outcomes (e.g., heart failure). Additionally, it lacks items relating to several DSM-IV criteria for panic, thereby limiting content validity. Reliability is also potentially compromised due to experimenter-coding of participant-generated responses. A modified form of the BSIQ was developed to address these limitations and evaluated with non-anxious controls (n=34) and people with panic disorder (n=38). The revised questionnaire demonstrated good to excellent internal consistency, inter-rater reliability, and construct validity and is a useful development of the BSIQ.

- Description: Clustering in gene expression data sets is a challenging problem. Different algorithms for clustering of genes have been proposed. However due to the large number of genes only a few algorithms can be applied for the clustering of samples. k-means algorithm and its different variations are among those algorithms. But these algorithms in general can converge only to local minima and these local minima are significantly different from global solutions as the number of clusters increases. Over the last several years different approaches have been proposed to improve global search properties of k-means algorithm and its performance on large data sets. One of them is the global k-means algorithm. In this paper we develop a new version of the global k-means algorithm: the modified global k-means algorithm which is effective for solving clustering problems in gene expression data sets. We present preliminary computational results using gene expression data sets which demonstrate that the modified k-means algorithm improves and sometimes significantly results by k-means and global k-means algorithms.

Monitoring the impact of occupational health and safety education

- Description: "This research investigated whether engineers, graduating from universities more than a decade after the introduction new occupational health and safety (OHS) legislation in Australia, were being equipped with the knowledge and skills to fulfil their professional, legal and moral responsibilities in relation to occupational health and safety. The study focussed on engineering students as future business leaders and designers of working environments. An instrument was designed to examine the ability of OH&S education to affect decision-making and problem solving competence in engineering students and graduates. The study found that engineering graduates in the 1990's were departing [from] their academic institutions with superficial knowledge of occupational health and safety responsibilities and accountability in the workplace. The evaluative tool identified an absence of safety management skills and knowledge within graduate and student engineer groups and an extensive urge to blame and discipline the victim or blame a government regulatory authority. The research found that although occupational health and safety professionals adopt a strategy of a safe work place rather than place emphasis on individual workers the engineers did not adopt the safe place approach and focussed on the person. It is recommended that the evaluative tool or a derivative of it should be used to evaluate the extent to which our community progresses in developing the vital OHS decision-making skills of the people who will manage and design workplaces." --p.ii.

- Description: Objective: To explore trends in the practice of mother-infant psychotherapy among perinatal psychiatry clinicians based in Melbourne. Methods: A cross-sectional survey with a purpose designed self-report questionnaire was used to assess the attitudes and practices of 47 perinatal and infant psychiatry clinicians in their use and understanding of mother-infant psychotherapy. Results: Seventy per cent of clinicians in this field of psychotherapy who responded to the questionnaire subscribe to a psychodynamic model, although cognitive behavioural models are also used. The interventions were mostly used in conjunction with other interventions, would be more accurately described as 'parent-infant psychotherapy', and non-psychiatrists in the area tended to be more likely to be formally trained in psychotherapy, but only 4% were formally trained in specific mother-infant psychotherapy. There was a unanimous request for further clinical training in this area. Conclusions: The emerging field of perinatal psychiatry needs to develop coherent therapeutic models and conduct outcome trials on specific interventions. Specific trainings in these models, in assessment and in diagnostic frameworks are required to enhance clinical efficacy, for research and service development purposes. © 2006 Royal Australian and New Zealand College of Psychiatrists.

- Description: We derive some Moore-like bounds for multipartite digraphs, which extend those of bipartite digraphs, under the assumption that every vertex of a given partite set is adjacent to the same number δ of vertices in each of the other independent sets. We determine when a multipartite Moore digraph is weakly distance-regular. Within this framework, some necessary conditions for the existence of a r-partite Moore digraph with interpartite outdegree δ > 1 and diameter k = 2m are obtained. In the case δ = 1, which corresponds to almost Moore digraphs, a necessary condition in terms of the permutation cycle structure is derived. Additionally, we present some constructions of dense multipartite digraphs of diameter two that are vertex-transitive.

Navigating their way : how do women with hospitalised premature infants perceive their roles in regional special care nurseries?

- Description: "Improved survival rates for premature infants have resulted in extended hospital stays in neonatal nurseries with consequent challenges for mothers assuming a parental role. Additionally, maternal medical complications associated with surgical birth, and a need to locate themselves in unfamiliar clinical environments, exacerbate women's experiences and transition to a maternal role competes with other roles at this time. For women living in rural and regional areas, who experience premature birth, there is additional hardship due to isolation, distance and limited support services. There has been little research on women's experiences with infants in special care nurseries in regional Australia."--(leaf ii).

- Description: The conjugate duality, which states that infx∈X φ(x, 0) = maxv∈Y ' −φ∗(0,v), whenever a regularity condition on φ is satisfied, is a key result in convex anal¬ysis and optimization, where φ : X × Y → IR ∪{+∞} is a convex function, X and Y are Banach spaces, Y ' is the continuous dual space of Y and φ∗ is the Fenchel-Moreau conjugate of φ. In this paper, we establish a necessary and sufficient condition for the stable conjugate duality, ∗ ∗ ∈ X' inf {φ(x, 0) + x ∗(x)} = max {−φ ∗(−x ,v)}, ∀x, x∈Xv∈Y ' and obtain a new global dual regularity condition, which is much more general than the popularly known interior-point type conditions, for the conjugate duality. As a consequence we present an epigraph closure condition which is necessary and sufficient for a stable Fenchel-Rockafellar duality theorem. In the case where one of the functions involved in the duality is a polyhedral convex function, we also provide generalized interior-point conditions for the epigraph closure condition. Moreover, we show that a stable Fenchel’s duality for sublinear functions holds whenever a subdifferential sum formula for the functions holds. As applications, we give general sufficient conditions for a minimax theorem, a subdifferential composition formula and for duality results of convex programming problems.

- Description: With age, gait functions reflected in the walking patterns degenerate and threaten the balance control mechanisms of the locomotor system. The aim of this paper is to explore applications of artificial neural networks for automated recognition of gait changes due to ageing from their respective gait-pattern characteristics. The ability of such discrimination has many advantages including the identification of at-risk or faulty gait. Various gait features (e.g., temporal-spatial, footground reaction forces and lower limb joint angular data) were extracted from 12 young and 12 elderly participants during normal walking and these were utilized for training and testing on three neural network algorithms (Standard Backpropagation; Scaled Conjugate Gradient; and Backpropagation with Bayesian Regularization, BR). Receiver operating characteristics plots, sensitivity and specificity results as well as accuracy rates were used to evaluate performance of the three classifiers. Cross-validation test results indicate a maximum generalization performance of 83.3% in the recognition of the young and elderly gait patterns. Out of the three neural network algorithms, BR performed superiorly in the test results with best sensitivity, selectivity and detection rates. With the help of a feature selection technique, the maximum classification accuracy of the BR attained 100%, when trained with a small subset of selected gait features. The results of this study demonstrate the capability of neural networks in the detection of gait changes with ageing and their potentials for future applications as gait diagnostics.
