Determinants of physical activity in middle school children

Objective: To evaluate the theory of reasoned action (TRA) and planned behavior (TPB) in predicting moderate-to-vigorous physical activity (MVPA) in sixth-grade youth. Methods: One hundred ninety-eight students completed a questionnaire measuring attitudes, subjective norms, perceived behavioral control, and intentions to be active. MVPA was measured using the CSA 7,164 accelerometer. Results: Although demonstrating an acceptable fit, the TRA and TPB accounted for only a small percentage of the variance in MVPA. In support of the TPB: the addition: of control perceptions to the reasoned! action model! added to the prediction of intentions and MVPA. Conclusion: Within our sample of sixth graders, the utility of the, TRA or TPB;as a framework for activity interventions appears to be limited.

Social competence and peer interactions of students with intellectual disability in an inclusive high school

This paper reports descriptive information on the relationship between social competence and the amount and type of peer interaction for nine adolescents with intellectual disability attending a regular high school. Each adolescent's social competence was assessed using the AAMR Adaptive Behavior Scale-School (2nd edn) (ABS-S:2). Naturalistic observations were conducted to obtain information on the amount and type of peer interaction. Data were analysed to determine the relationship between social competence and peer interactions. Social competence was not consistently correlated with the amount of peer interaction. Results from the naturalistic observations showed individual differences in patterns of peer interaction with a tendency towards more frequent interactions with peers who also had intellectual disabilities. These data suggest that social competence did not significantly influence the amount and type of peer interaction. Implications for facilitating peer interactions between adolescents with and without intellectual disability are discussed.

Diversity and change in Australia's rangelands: a post-productivist transition with a difference?

Australia's rangelands are experiencing a post-productivist transition at a tempo comparable to Western Europe's, but in contexts that ensure marked divergence in impulses, actors, processes and outcomes. In Australia's most marginal lands, a flimsy mode of pastoral occupance is being displaced by renewed indigenous occupance, conservation and tourism, with significant changes in land ownership, property rights, investment sources and power relations, but also with structural problems arising from fugitive income streams. The sharp delineation between structurally coherent commodity-oriented regions and emerging amenity-oriented regions can provisionally be mapped at a national scale. A comparison of Australia with Western Europe indicates that three distinct but interconnected driving forces are propelling the rural transition, namely: agricultural overcapacity; the emergence of amenity-oriented uses; and changing societal values.

Rural lines of flight: Telecommunications and post-metro dreaming

Information and communications technologies hold a prominent place in the cultural imagination of many people living outside the Australian metropolis, especially recent émigrés. A vision of a wired pastoral conjures up the possibilities of city work, connections and pleasures accompanying the flight to the country. Such aspirations have given a twist to one of the great topos of Australian post-invasion communications history, communications ameliorating the perceived isolation in the bush. This article examines important changes to rural telecommunications in the 1990s coinciding with post-metro dreaming and digital convergence, namely the rise of local telecommunications. Neo-Foucauldian accounts of citizenship hold some promise for explaining the criss-cross of tangled lines of flight in regional communications in the twenty-first century: emergent subjectivities, utopian digital modes of becoming, new politics of infrastructure, reconfigured relationships among state, market and citizen.

Harmful drinking in military veterans with post-traumatic stress disorder: Association with the D2 dopamine receptor A1 allele

Aims: The frequency of the Taq I A alleles (A1 and A2) of the D2 dopamine receptor (DRD2) gene was examined in Caucasian post-traumatic stress disorder (PTSD) patients and controls. Results: In 91 PTSD patients, the frequency of the A1 allele was higher (P = 6.12 x 10(-3)) than in the 51 controls. In the 38 PTSD harmful drinkers (greater than or equal to60 g alcohol/day), A1 allelic frequency was higher (P = 3.91 x 10(-2)) than in the 53 non-harmful drinkers (

Comparison of tafenoquine (WR238605) and primaquine in the post-exposure (terminal) prophylaxis of vivax malaria) in Australian Defence Force personnel

On return from duty in North Solomons Province (including Bougainville Island), Papua New Guinea, 586 Australian Defence Force personnel received either primaquine (14-d) or tafenoquine (3-d) post-exposure malaria prophylaxis. Within 12 months, 6 of the 214 volunteers receiving primaquine and 7 of 378 receiving tafenoquine had developed vivax malaria. Overall, volunteers preferred the shorter course of tafenoquine.

Post-discharge surveillance: can patients reliably diagnose surgical wound infections?

Post-discharge surgical wound infection surveillance is an important part of many infection control programs. It is frequently undertaken by patient self-assessment, prompted either by a telephone or postal questionnaire. To assess the reliability of this method, 290 patients were followed for six weeks post-operatively. Their wounds were photographed and also covertly assessed for signs of infection by two experienced infection control nurses (ICNs). Patients also responded to a postal questionnaire seeking evidence of infection at both week four and week six post-surgery. Correlation between the patient's assessment of their wound and the ICNs diagnosis was poor (r = 0. 37) with a low positive predictive value (28.7%), although negative predictive value was high (98.2%). Assessment of photos for signs of infection by two experienced clinicians also correlated poorly with the ICNs diagnosis of infection (r = 0.54). The patient's recall of prescription of an antibiotic by their general practitioner (GP) for wound infection during the postoperative period correlated best with the ICNs diagnosis (r = 0.76). This latter measure, particularly when confirmed by the GP in those patients reporting an infection, appears to provide the most valid and resource efficient marker of post-discharge surgical wound infection.
