    Notes: In situ temperature-dependent spin-polarized cascade electron spectroscopy is used to study exchange coupling processes between a magnetic substrate and a magnetic overlayer separated by a nonferromagnetic spacer layer. Relative Auger intensities of the overlayer/substrate configurations as a function of overlayer coverage together with a model by Ossicini are used to evaluate the degree to which these trilayer structures grow by a continuous layer growth mode. Measurement of the spin polarization and Auger spectroscopy are used during film growth as criteria of chemical film purity. Evidence will be given to show that the oscillatory magnetic coupling behavior as a function of Cr thickness of a NiFe/Cr/NiFe trilayer changes significantly depending on the deposition temperature, which may be associated with microstructural changes. Competing coupling mechanisms are thought to account for this behavior. Data will also be presented to suggest how trace quantities of residual gas sorbates, presumably acting as surfactants, can dramatically alter the magnetization behavior of ultrathin films. Significant increases in magnetization of a 5-A(ring) Fe overlayer film in a Fe/Ta/Fe trilayer structure were observed and are attributed to changes in wetting characteristics at the Fe/Ta interface which cause morphological changes in the film structure. Conversion of weakly interacting magnetic islands to a long-range ferromagnetic continuous film medium exhibiting remanence and a steady-state Brillouin functional M(T ) behavior is thought consistent with these observations. The possible significance of these kinds of observations to some conflicting data in the literature will be mentioned.

    Notes: A household production function is developed which allows for persons to be engaged in more than one activity at a point in time. Labour inputs are scaled back when two activities are being undertaken. Data from the 1987 Australian Time Use Survey is used to estimate equations explaining input hours into home production by adult members of the household. One implication of the empirical results is that when two activities are being undertaken simultaneously input hours on the activity coded as “primary” and the input hours on the activity coded as “secondary” should each have a weight of one-half.

    Notes: The design and operating properties of a GaAs polarized electron source are presented. An electron optical system is described that passes more than 80% of the emitted electrons at 10 μA to the target under low-energy (7–20 eV) parallel beam conditions. Laser excitation can give rise to abnormal energy distributions of the photoemitted electron beam. The existence of longitudinal modes gives a possible explanation for this behavior, which can be avoided using a mode stabilized light source. The overall performance of the polarized electron source is demonstrated by inverse photoemission spectra from Ni(110).

    Notes: Background/purpose: The study was performed to investigate the transepidermal water loss (TEWL) and pH-value in patients in intensive care.Methods: Forty intensive-care patients (22 men, 18 women) were included in the study. TEWL and pH-values were measured at admission, and after 24, 96 and 168 h. The areas of measurement were the forehead, the volar forearm, paraumbilical and the ventral thigh. The measurements were made under standardized environmental conditions according to the recommendations of the EMCO Group.Results: Elevated values were found on the forehead compared with the other skin areas examined. There was no significant change in mean TEWL-values in any patient in the course of the study. There was also no significant influence of TEWL at the time of admission on the prognosis. The course analysis of the mean pH-values, however, showed that patients who developed a systemic inflammatory response syndrome (SIRS) or sepsis during the further course had a higher pH-value over the entire study period.Conclusion: TEWL and the pH of the skin surface could be measured at bedside in the intensive-care unit and delivered reproducible results. These parameters appear, however, to be relevant only for subgroups of patients under intensive care.

    Notes: Aim  To develop and evaluate a brief intervention for reducing risk behaviours associated with HCV transmission in injecting drug users (IDU).Design  Randomized controlled trial of an individually tailored brief behavioural intervention (BBI) (experimental) versus a standardized educational intervention (control).Setting  Specialist drug treatment facility in Melbourne, Australia.Participants  One hundred and forty-five IDU (aged 18 or over, injecting at least weekly in the preceding 6 months) recruited and randomized to the experimental condition (n = 73) or the control condition (n = 72).Interventions  The BBI was based on the Blood-Borne Virus Transmission Risk Assessment Questionnaire (BBV-TRAQ)—a standardized blood-borne virus risk assessment instrument comprising injecting risk, sexual risk and other skin penetration risk subscales. The BBV-TRAQ was used to identify individual HCV risk practices and to tailor the 30-minute experimental BBI. Control participants received a standardized HCV educational session, using current educational materials.Main outcome measures  BBV-TRAQ subscale and total scores and measures of participant satisfaction.Results  One hundred and twenty-four participants (86%) were followed-up at 4 weeks (±7 days). Analyses revealed a significant reduction in HCV risk behaviours for both groups at 1-month follow-up, with participants in the experimental BBI condition reporting higher overall satisfaction with the intervention compared to the control group.Conclusions  Both groups reported significant reductions in risk behaviour, indicating that while BBI methods hold promise for HCV education and prevention, they were not demonstrated to be more effective than the provision of standard educational materials. Future research could evaluate the efficacy of the BBV-TRAQ as a risk behaviour intervention and counselling tool in clinical, NSP and peer education settings.

    Notes: Aim  To compare alternative survey methods for estimating (a) levels of at risk alcohol consumption and (b) total volume of alcohol consumed per capita in comparison with estimates from sales data and to investigate reasons for under-reporting.Setting  The homes of respondents who were eligible and willing to participate.Participants  A total of 21 674 Australians aged 14 years and older.Design  A 2001 national household survey of drug use, experiences and attitudes with weights applied for age, sex, geographic location and day of week of interview.Measures  Self-completion questionnaire using quantity–frequency (QF) and graduated–frequency (GF) methods plus two questions about consumption ‘yesterday’: one in standard drinks, another with empirically based estimates of drink size and strength.Results  The highest estimate of age 14 + per capita consumption of 7.00 l of alcohol derived from recall of consumption ‘yesterday’ or 76.8% of the official estimate. The lowest was QF with 49.8%. When amount consumed ‘yesterday’ was recalled in standard drinks this estimate was 5.27 l. GF questions yielded higher estimates than did QF questions both for total volume (5.25 versus 4.54 l) and also for the proportion of the population at risk of long-term alcohol-related harm (10.6%versus 8.1%). With the detailed ‘yesterday’ method 61% of all consumption was on high risk drinking days.Conclusions  Questions about typical quantities of alcohol consumed can lead to underestimates, as do questions about drinking ‘standard drinks’ of alcohol. Recent recall methods encourage fuller reporting of volumes plus more accurate estimates of unrecorded consumption and the proportion of total alcohol consumption that places drinkers at risk of harm. However, they do not capture longer-term drinking patterns. It is recommended that both recent recall and measures of longer-term drinking patterns are included in national surveys.
