The Australian Government has committed to reducing Indigenous disadvantage, including closing the life-expectancy gap within a generation, and to halving the gap in mortality rates for children under 5 years of age within a decade. Sixty per cent of the health gap between Indigenous and non-Indigenous Australians is attributable to the health of Indigenous people living in non-remote areas of Australia. We conducted a brief review of recent Australian original research publications on the health of the 53% of Indigenous people who live in urban areas, and found that data are sparse; there were only 63 studies in the past 5 years (11% of all articles about Indigenous health during this period). Although Indigenous Australians living in remote areas experience greater health disparity, the government will not achieve its aims without paying due attention to the non-remote-living population. More research is required, and particularly research that actually tests the impact of policies and programs. [ABSTRACT FROM AUTHOR]

U.S. museums were not founded with the intention of building large collections reflecting the history and culture of classical societies such as Mesopotamia, Greece, Rome, and Egypt. Only later, with the combined interest of trustees and private donors, did most museums accept classical archaeology as an academic pursuit. In this paper, I explore how museums in the American Midwest, not known for maintaining extensive classical collections, came to possess relatively large collections from classical societies. I intend in this paper to engender pragmatic lines of questioning regarding the nature of archaeological and anthropological museum studies. I specifically focus on the development of collections at the Field Museum of Natural History in Chicago, the Science Museum of Minnesota in St. Paul, and the Logan Museum of Anthropology in Beloit, WI.

BACKGROUND: Even among countries that have ratified the United Nations Convention on the Rights of the Child there is much disagreement about corporal punishment of children. Last year the Scottish Executive proposed a new law banning the smacking of children under the age of three, becoming the tenth European nation to do so. The proposal, currently abandoned whilst ostensibly still under debate, has raised a wave of controversy in child protection circles. In the nearest neighbouring country, England, a similar proposal was robustly rejected. PURPOSE OF THE PAPER: Given an increasing family and community focus in nursing, the implications of the debate for the profession cannot be ignored. What should we be telling 'ordinary' families about smacking? Thus this paper presents a positional statement on the smacking controversy and outlines some pointers for practice. DISCUSSION: While for many the legislation proposed does not go far enough, others decry it as a breach of parental rights and, thus, the issue has become hugely controversial. Media opinion and various opposing campaigns dominate both public and professional spheres. Rights, responsibilities, examples from other countries, culture and gender are all used as fodder in the debate. Extreme examples are cited by both sides and used as grist for what are at times tenuous arguments. As there is even a division within child protection arenas, practising professionals may struggle to find a way through the maze of seemingly contradictory findings from research, policy and opinion. CONCLUSIONS: A wide range of literature suggests that both public and professional opinion is divided on the use of smacking as a form of discipline of young children. Opinion is also divided on the ability of legislation to bring about change in social attitudes and behaviour. Health care professionals need to be in a position to recommend best practice and to do so consistently. [ABSTRACT FROM AUTHOR]

OBJECTIVES: To explore women's experience of being diagnosed with ductal carcinoma in situ (DCIS) in relation to the following: response to the diagnosis; understanding about the diagnosis; satisfaction with information; satisfaction with the level of involvement in treatment decision-making and satisfaction with support services. DESIGN: An explorative descriptive qualitative design was used to facilitate an in-depth exploration of women's experiences. SETTING AND PARTICIPANTS: Five focus group interviews were conducted in New South Wales (NSW), Australia, involving 26 women diagnosed with DCIS. RESULTS: DCIS is a non-invasive breast disease, that in most cases will not recur if treated, and cannot of itself metastasize to other parts of the body. However, this study found that women were confused about whether or not they had cancer that could result in death. Women's confusion was compounded by the use of the term 'carcinoma' and by the recommendation of treatments such as mastectomy. Women's confusion was not alleviated by appropriate information, with most women reporting dissatisfaction with the information they received specifically about DCIS. CONCLUSIONS: This study identifies that a diagnosis of DCIS has a significant psychological impact on women. The communication challenges highlighted in this study are not only relevant to DCIS but to any other disease in which the natural history is uncertain and the evidence about treatment effectiveness is still emerging. Further research is needed in areas such as DCIS to explore the difficulties experienced in doctor-patient communication and their impact on patient outcomes, and how to optimize doctor-patient communication.

Aim Methods Results Conclusion Many trials have demonstrated the efficacy of specific therapy modalities for individuals with attenuated psychosis symptoms (APS). Less is known regarding mechanisms behind positive outcomes, including the role of nonspecific therapeutic factors. This study explored working alliance (WA) in a clinic serving individuals with APS to see how WA changed across the course of treatment and its relation to APS.Session level APS and WA data was available for 12 individuals of diverse racial and gender identity, (M = 48 sessions each). Multilevel models with random intercepts tested change in WA and APS over time, and cross‐sectional and prospective relations.WA increased and APS decreased over time. Cross sectionally, WA and APS were inversely related. Prospective relations were non‐significant.When symptoms increase, therapists for individuals with APS should be attentive to potential disruptions in WA, though strong WA may be a cross‐sectional protective factor.

Objective: To describe the basis for entheseal-associated bone disease in the spondylarthritides, by analyzing microanatomic and histopathologic relationships between soft tissue, bone cortex, and adjacent trabeculae., Methods: Serial sections from 52 entheses were examined; these entheses encompassed small and large insertions in the upper limb (n = 21), lower limb (n = 27), and spine (n = 4) from 60 cadavers. Enthesis microdamage (fissuring) as well as vascular and reparative changes were evaluated. Contact radiographs were used to ascertain the relationship between entheses and the trabecular network., Results: At virtually all fibrocartilaginous entheses, the deep cortical boundary was extremely thin (typically 50-600 microm) or indistinguishable, and 96% of entheses had small holes in the cortical shell (typically 100-400 microm wide). Such regions were frequent sites of bone formation and renewal (96%) and microdamage (31%); these changes were more common in the lower limb. The presence of blood vessels near holes in the cortical shell was common; in 85% of attachments, blood vessels were present on the soft tissue side of the enthesis. Highly orientated trabeculae were more obvious in the lower limb than the upper limb (59% versus 29%)., Conclusion: The trabecular network supporting the cortical shell is an integral part of the enthesis, transferring load to an extensive skeletal region. In many cases, tendons/ligaments are anchored directly to such networks. This functional integration is associated with microdamage and repair at the hard tissue-soft tissue interface. These findings have implications for understanding bone involvement in SpA and for the SpA concept in general, especially the hypothesis that enthesis-bone architecture may be important in disease initiation.

Objective: The Achilles tendon insertion is associated with a complex of adjacent fibrocartilages, a bursa, and a fat-pad, and is functionally much more than a focal insertion. This has important implications for a better understanding of the spondylarthropathies (SpA). However, the degree to which other insertions form comparable "enthesis organs" has not been established. The aim of this study was to demonstrate the applicability of the enthesis organ concept to other insertion sites., Methods: Both joint-related (articular) and extraarticular entheses were removed from 28 sites in the limbs of formalin-fixed cadavers (age at death 70-101 years) that had been donated for anatomic study. The samples were prepared for paraffin histologic analysis and sectioned longitudinally. The presence and extent of enthesis organs was evaluated at each site in serial sections stained with Masson's trichrome and toluidine blue., Results: Articular enthesis organs were found at 14 entheses, including the attachments of the digital extensor tendons and collateral ligaments, the cruciate ligaments, tibialis anterior, the lateral collateral ligament of the knee, and the popliteal tendon. Extraarticular enthesis organs were seen at 2 sites, the biceps brachii and patellar tendon insertions. In all enthesis organs, sesamoid and/or periosteal fibrocartilage was present in close association with synovium., Conclusion: The concept of an enthesis organ is of general significance in understanding attachment sites and may explain the diverse pathologic changes, including synovitis, bursitis, and extracapsular changes, seen adjacent to tendon/ligament entheses in SpA. These findings may provide insight into the reason the target tissues in SpA are apparently so diverse., (Copyright 2004 American College of Rheumatology)

This study examined the prevalence and predictors of smoking by pregnant women attending a public antenatal clinic. The prevalence of smoking in this population (n = 2577) was found to be 38.0% (95% CI 36.1-39.9%). A review of previous research investigating variables associated with smoking in pregnancy indicated that only three of 42 studies had used multivariate analysis. Using step-wise logistic regression analysis, five variables were found to be independent predictors of smoking in pregnancy: education (having 4 years or less high school), marital status (being unmarried), gravidity (being multigravida), age (being under 25 years) and language spoken at home (speaking English). The model correctly predicted 63.7% of cases. The knowledge and attitudes of pregnant smokers were also investigated using data from a sub-sample of consenting subjects. Three-quarters of the women claimed that they had reduced their smoking since discovering they were pregnant. However, their mean intake of 13.7 cigarettes daily remained at a hazardous level. Approximately half (51%) these smokers claimed to have tried to quit smoking in the current pregnancy. Most (61%) women said they believed smoking was definitely harmful to the unborn child. However, awareness and acceptance of specific risks were inadequate. Of the women in a current relationship, 72% said their partner was a regular smoker. Less than half (45%) the continuing smokers who had seen a doctor about their current pregnancy could recall being advised to stop smoking. There is a need for health care providers to adopt a more systematic and tailored approach to smoking cessation counselling. Efforts to convert quit attempts in pregnancy into sustained cessation represent a priority area of programme development and evaluation.

1. The induction of long-term potentiation (LTP) at excitatory synapses on CA1 pyramidal neurons occurs partly through an increase in the quantal AMPA current. It is also accompanied by an increase in the number of active sites. Any presynaptic modification, requiring the presence of a retrograde messenger, remains uncertain. 2. There are no definitive data that establish a causal link between LTP and the formation of memories. Pharmacological blockage of NMDA and mGLU receptors and genetic mutants with proteins deleted that are thought to be involved in LTP induction or maintenance or in the formation of memories have all linked deficits in LTP with impairments to behavioural learning, but these links are not necessarily causal. The development of tissue- and time-specific lesion of gene expression for multiple gene products may overcome the present limitations of gene deletion experiments and provide more revealing insights into the relationship between LTP and memory.

Smoking is a major cause of adverse pregnancy outcomes. However limited data are available documenting the perceptions of care providers in this area. This mail survey undertaken in 1992-1993 aimed to assess the smoking cessation practices of Australian public antenatal clinics. Questionnaires were returned by 140 (80%) of the 175 eligible hospitals, 83 (48%) medical directors and 108 (62%) nursing directors. Smoking advice was rated an essential activity at the first antenatal visit by 69% of responding directors. Nonetheless, only 12% of clinics indicated they offered relevant training and 4% reported written policies. Results also indicate senior staff may have suboptimal levels of awareness of smoking risks. Clinics used a narrow array of strategies to promote cessation. Almost one-third of directors said they advised smokers to cut down rather than stop smoking completely. There is a need for antenatal clinics to implement integrated strategies for the detection and treatment of pregnant smokers including staff training and modifications to the clinics' environment. In addition, major health promotion agencies need to develop effective smoking cessation programmes designed specifically for use in antenatal clinics and to monitor their on-going implementation.

The use of both licit and illicit drugs has been identified as a major health issue for Australian Aborigines. However, data on the proportion of people who use such drugs is scant. This cross-sectional survey of a randomly selected sample of urban Aboriginal people provides information on the use of the drugs alcohol, tobacco, marijuana, cocaine, heroin as well as petrol sniffing. Overall, a significantly smaller proportion of Aboriginal people were found to be current alcohol drinkers compared to non-Aboriginal Australians. A larger proportion of these drinkers were, however, found to be drinking at levels that were hazardous to their health. A significantly greater proportion of people from the Aboriginal sample were also found to be smokers compared to their non-Aboriginal counterparts. An examination of the use of the illicit substances revealed that a greater proportion reported they had ever used marijuana, compared to the other substances. The findings are discussed in terms of their implications for the health of Aboriginal people.

The evaluation of the efficiency and effectiveness of antenatal education programmes has been identified as a priority in improving maternity services in Australia. Two hundred and ninety four primiparas completed a brief questionnaire in the 3 days following delivery; 82% of the women surveyed attended antenatal education classes. Women were less likely to attend if they were single, younger than 26 years, had lower levels of education, received care during pregnancy from the antenatal clinic and did not have private health insurance. Attenders at antenatal education were also more likely to plan on breast feeding, to be nonsmokers and to know of a greater number of community organizations to help new mothers. However, logistic regression analyses indicated that, with the exception of number of community organizations known, these differences were attributable to demographic differences between attenders and nonattenders. One hundred and forty two women and their partners attending the major provider of antenatal education classes in Newcastle were surveyed prior to and following classes. Significant increases in knowledge were evident following the programme among both women and their partners. Satisfaction with the programme was high as indicated by a large proportion of respondents attending all 4 classes, most programme components being reported as useful or very useful and only a small proportion of respondents experiencing problems with the programme.

A community survey of 8,896 households was undertaken in the Hunter region of New South Wales to assess women's health status. Consent was gained from 5,781 of the 6,361 eligible women between 18 and 69 years of age. The prevalence of hysterectomy in this sample was 16.9%, with 34.2% of women in their fifties having had a hysterectomy. Most hysterectomies (75%) were performed on women between the ages of 30 and 49 years. The demographic variables of parent's country of birth, educational level and employment status predicted recent hysterectomies after controlling for the effect of age.

Distributions of reinforcers between two components of multiple variable-interval schedules were varied over a number of conditions. Sensitivity to reinforcement, measured by the exponent of the power function relating ratios of responses in the two components to ratios of reinforcers obtained in the components, did not differ between conditions with 15-s or 60-s component durations. The failure to demonstrate the "short-component effect," where sensitivity is high for short components, was consistent with reanalysis of previous data. With 60-s components, sensitivity to reinforcement decreased systematically with time since component alternation, and was higher in the first 15-s subinterval of the 60-s component than for the component whose total duration was 15 s. Varying component duration and sampling behavior at different times since component transition may not be equivalent ways of examining the effects of average temporal distance between components.

Pigeons' responses were reinforced in two components of several multiple variable-interval variable-interval schedules of food reinforcement. In one component, the key was illuminated green for 15 seconds and white for 45 seconds. In the other component, the key was illuminated red for 15 seconds and white for 45 seconds. Values for the exponent of the power functions relating response ratios to reinforcement ratios were higher in the presence of the discriminative stimuli (green or red) than in the presence of white. Sensitivity of response ratios to changes in reinforcement ratios provided an index of the extent to which responding was under delayed stimulus control by prior discriminative stimuli.
