The global incidence of diabetes is increasing at epidemic rates. Estimates suggest there are currently 150 million people with diabetes and this number is expected to double in the next 20 years. Type 2 diabetes accounts for 95% of all cases and is characterized in part by impaired sensitivity to insulin or 'insulin resistance'. Defects in the insulin signalling pathways underpin this resistance. In the current article we discuss the regulation of Insulin Receptor Substrate-1 (IRS-1), a protein that plays a pivotal role in insulin signalling and whose function is impaired in subjects with insulin resistance. Coordination of IRS-1 function is multi-faceted, involving phosphorylation of IRS-1 at multiple serine/threonine residues. This controls many aspects of IRS-1, including its interaction with the insulin receptor and subsequent tyrosine phosphorylation, as well as its subcellular distribution and targeting for degradation by the proteasome. Such tight control ensures appropriate transduction and attenuation of the insulin signal, thereby regulating insulin action in healthy individuals. Emerging evidence indicates that `diabetogenic factors' associated with insulin resistance, such as TNFalpha and elevated circulating fatty acids, impact on insulin signalling at the level of IRS-1 serine/threonine phosphorylation. The expression and/or activity of several kinases, such as IkappaB kinase beta (IKKbeta) and salt-induced kinase 2 (SIK2), and the phosphorylation of IRS-1 at key sites, such as Ser307 and Ser789, are increased in states of insulin resistance. Identifying the pathways by which such factors activate these and other kinases, and de. ning the precise roles of specific serine/threonine phosphorylation events in IRS-1 regulation, represent important goals which may eventually provide a rationale for therapeutic intervention.

Issues addressed: The study was designed to gain an understanding of health promotion from the perspective of oral health professionals employed in the public sector during a transition in the focus of services. Methods: A cross sectional survey of oral health professionals employed by Queensland Health was conducted between March and April 2001. Staff were randomly sampled from employment records. A proportionate random sample, stratified across professional groups and geographical zones, was selected. Results: While the majority of the health professionals surveyed perceived oral health promotion to be part of their role, they felt ill equipped to adopt it. Professional groups differed in their confidence and perception of how to promote health in their clinical setting, existing barriers they encountered and their participation in health promotion programs. Conclusions: Strategies to improve the adoption of the oral health promotion role within Queensland public oral health services include: regular in- service and education for all staff regarding health promotion issues; increased cohesion of the oral health team; intersectorial collaboration; supportive district management; and a refocus to primary health care and public health concepts

This paper outlines a multiprofessional education workshop piloted and subsequently conducted with a cohort of 81 graduate entry students of occupational therapy, physiotherapy, speech pathology and audiology. The rationale for, and format of, the workshop is outlined, followed by comparisons between students' knowledge about teamwork prior to and after the four-hour workshop. The workshop was based on a real case scenario of a child with Developmental Coordination Disorder (DCD). Students completed pre- and post-workshop questionnaires about their knowledge of DCD, teamwork and the roles of various professionals and parents; and a post-workshop questionnaire about their views regarding the utility of the workshop, its strengths, and learning outcomes. The evaluation indicated that the workshop was overwhelmingly successful from the students' perspective in: (1) enhancing their understanding about DCD and its multifaceted impact on school age children; (2) developing a deeper appreciation of the importance of teamwork itself; (3) refining their understanding of their own profession's role and (4) developing an appreciation of the role of other professions and parents in working with children with complex needs, and their families. Limitations of this study and directions for future research are discussed.

Australia has experienced a polarization of income and labour market outcomes over the past 20 years (GREGORY and HUNTER, 1995; HARDING, 1996). This has taken an increasingly spatial dimension (HUNTER. 1995a, 1995b), giving rise to concerns that the spatial pooling of disadvantage may hamper the labour market outcomes of youth growing up in poorer residential areas. This paper explores the role that the differential neighbourhood 'quality' of an individual's residential area at age 16 has on their labour market outcomes at age 18 and age 21. Evidence is found that youth who live in poorer quality neighbourhoods face an increased likelihood of being unemployed at both the age of 18 and 21, even after controlling for personal and family characteristics.

On a viewpoint of gender differences in Cd body burden and its health effects, we reviewed the population- based research including our own which conducted in Japan, Thailand, Australia, Poland, Belgium and Sweden to assess health effects of human exposure to environmental cadmium and their potential mechanisms. As a result, six risk factors in Cd health effects in women have been identified; ( 1) more serious type of renal tubular dysfunction, ( 2) difference in calcium metabolism and its regulatory hormones, ( 3) kidney sensitivity; difference in P450 phenotype, ( 4) pregnancy, ( 5) body iron store status, and ( 6) genetic factors. Further studies of Cd toxicity targeted to women would now appear necessary.

A 16-nation study involving 8,360 participants revealed that hostile and benevolent attitudes toward men, assessed by the Ambivalence Toward Men Inventory (P. Glick & S. T. Fiske, 1999), were (a) reliably measured across cultures, (b) positively correlated (for men and women, within samples and across nations) with each other and with hostile and benevolent sexism toward women (Ambivalent Sexism Inventory, P. Glick & S. T. Fiske, 1996), and (c) negatively correlated with gender equality in cross-national comparisons. Stereotype measures indicated that men were viewed as having less positively valenced but more powerful traits than women. The authors argue that hostile as well as benevolent attitudes toward men reflect and support gender inequality by characterizing men as being designed for dominance.
