Studying landscape evolution of the Earthís surface is difficult because both tectonic forces and surface processes control its response to perturbation, and ultimately, its shape and form. Researchers often use numerical models to study erosional response to deformation because there are rarely natural settings in which we can evaluate both tectonic activity and topographic response over appropriate time scales (103-105 years). In certain locations, however, geologic conditions afford the unique opportunity to study the relationship between tectonics and topography. One such location is along the Dragonís Back Pressure Ridge in California, where the landscape moves over a structural discontinuity along the San Andreas Fault and landscape response to both the initiation and cessation of uplift can be observed. In their landmark study, Hilley and Arrowsmith (2008) found that geomorphic metrics such as channel steepness tracked uplift and that hillslope response lagged behind that of rivers. Ideal conditions such as uniform vegetation density and similar lithology allowed them to view each basin as a developmental stage of response to uplift only. Although this work represents a significant step forward in understanding landscape response to deformation, it remains unclear how these results translate to more geologically complex settings. In this study, I apply similar methodology to a left bend along the San Andreas Fault in the Santa Cruz Mountains, California. At this location, the landscape is translated through a zone of localized uplift caused by the bend, but vegetation, lithology, and structure vary. I examine the geomorphic response to uplift along the San Andreas Fault bend in order to determine whether predicted landscape patterns can be observed in a larger, more geologically complex setting than the Dragonís Back Pressure Ridge. I find that even with a larger-scale and a more complex setting, geomorphic metrics such as channel steepness index remain useful tools for evaluating landscape evolution through time. Steepness indices in selected streams of study record localized uplift caused by the restraining bend, while hillslope adjustment in the form of landsliding occurs over longer time scales. This project illustrates that it is possible to apply concepts of landscape evolution models to complex settings and is an important contribution to the body of geomorphological study.

The reform of Australian mental health services has resulted in new models of care and changed work practices for all mental health professionals. Occupational therapists today are as likely to be working in multidisciplinary teams performing a range of generic clinical roles as they are to be working in specialist rehabilitation units. These kinds of changes have taken place in other countries, with anecdotal and some empirical evidence that the changes have resulted in concerns about loss of professional identity and roles. This study sought to identify the current work activities carried out by occupational therapists and to determine whether there was a discrepancy between their actual and desired work activities. It was expected that, overall, they would indicate a preference to do more specialist rehabilitation focused work and less generic case management work. A survey of 196 occupational therapists investigated their actual and preferred work activities in 55 specific roles across four broad categories (senior administration, specialist clinical, general clinical and community development). As expected, the participants indicated that they would prefer to be undertaking more specialist rehabilitation oriented work activities than they were actually doing. Contrary to expectations, they also wished to undertake more rather than less generic clinical work activities, to be more engaged in community development work and to take on more senior and administrative roles. They indicated a preference for less rather than more activity on only 5 of the 55 work roles examined. On examining a subset of 113 participants who reported that 50% or more of their time was spent in case management, there was greater evidence of resistance to generic clinical roles. It was therefore concluded that occupational therapists in Australia are seeking to deploy their specialist skills to a greater degree than the current practice environment permits. They have broadly accepted the generic roles required in multidisciplinary community case management, but those who are actually working in these roles are most likely to have reservations about this kind of work.

Objective To give an account of the views held by Australian veterinarians who work with horses on the future of their professional field. Method Questionnaires were mailed to 866 veterinarians who had been identified as working with horses, and 87% were completed and returned. Data were entered onto an Excel spreadsheet, and analysed using the SAS System for Windows. Results Their future prospects were believed to be very good or excellent by >60% of equine veterinarians but by only 30% of mixed practitioners seeing < 10% horses. The main factors believed likely to affect these prospects were the strength of the equine industries and the economic climate affecting horse owners, followed by the encroachment of cities into areas used for horses, competition from other veterinarians including specialist centres and from non-veterinary operators, and their ability to recruit and retain veterinarians with interest, experience and skill with horses. Urban encroachment, competition and recruitment were especially important for those seeing few horses. Concerns were also expressed about the competence and ethical behaviour of other veterinarians, the physical demands and dangers of horse work, the costs of providing equine veterinary services and of being paid for them, the regulatory restrictions imposed by governments and statutory bodies, the potential effects of litigation, and insurance issues. For many veterinarians in mixed practice these factors have reduced and are likely to reduce further the number of horses seen, to the extent that they have scant optimism about the future of horse work in their practices. Conclusion Economic and local factors will result in an increasing proportion of equine veterinary work being done in specialised equine centres, and the future of horse work in many mixed practices is, at best, precarious. A key factor influencing future prospects will be the availability of competent veterinarians committed to working with horses.

Data provided by 400 first year undergraduate students were analysed to develop two short forms of the Eysenck Personality Profiler (EPP) in which each of the 22 primary scales is assessed by a 6-item and a 12-item version instead of the usual 20-item per scale measure. In comparison with the 6-item per scale measure, the 12-item version retains more of the characteristics of the long version and seems a good compromise between quality of data and administration time.

1. We analysed time-series data from populations of red kangaroos (Macropus rufus, Desmarest) inhabiting four areas in the pastoral zone of South Australia. We formulated a set of a priori models to disentangle the relative effects of the covariates: rainfall, harvesting, intraspecific competition, and domestic herbivores, on kangaroo population-growth rate. 2. The statistical framework allowed for spatial variation in the growth-rate parameters, response to covariates, and environmental variability, as well as spatially correlated error terms due to shared environment. 3. The most parsimonious model included all covariates but no area-specific parameter values, suggesting that kangaroo densities respond in the same way to the covariates across the areas. 4. The temporal dynamics were spatially correlated, even after taking into account the potentially synchronizing effect of rainfall, harvesting and domestic herbivores. 5. Counter-intuitively, we found a positive rather than negative effect of domestic herbivore density on the population-growth rate of kangaroos. We hypothesize that this effect is caused by sheep and cattle acting as a surrogate for resource availability beyond rainfall. 6. Even though our system is well studied, we must conclude that approximating resources by surrogates such as rainfall is more difficult than previously thought. This is an important message for studies of consumer-resource systems and highlights the need to be explicit about population processes when analysing population patterns.

Objectives: To validate the WOMAC 3.1 in a touch screen computer format, which applies each question as a cartoon in writing and in speech (QUALITOUCH method), and to assess patient acceptance of the computer touch screen version. Methods: The paper and computer formats of WOMAC 3.1 were applied in random order to 53 subjects with hip or knee osteoarthritis. The mean age of the subjects was 64 years ( range 45 to 83), 60% were male, 53% were 65 years or older, and 53% used computers at home or at work. Agreement between formats was assessed by intraclass correlation coefficients (ICCs). Preferences were assessed with a supplementary questionnaire. Results: ICCs between formats were 0.92 (95% confidence interval, 0.87 to 0.96) for pain; 0.94 (0.90 to 0.97) for stiffness, and 0.96 ( 0.94 to 0.98) for function. ICCs were similar in men and women, in subjects with or without previous computer experience, and in subjects below or above age 65. The computer format was found easier to use by 26% of the subjects, the paper format by 8%, and 66% were undecided. Overall, 53% of subjects preferred the computer format, while 9% preferred the paper format, and 38% were undecided. Conclusion: The computer format of the WOMAC 3.1 is a reliable assessment tool. Agreement between computer and paper formats was independent of computer experience, age, or sex. Thus the computer format may help improve patient follow up by meeting patients' preferences and providing immediate results.

Morningness scales have been translated into several languages, but it lack of normative data and methodological differences make cross-cultural comparisons difficult. This study examines the psychometric properties and factor structure of the Composite Scale of Morningness (CSM) in samples from five countries: France (n = 627), Italy (n, = 702), Spain (n = 391), Thailand (n. = 503), and Australia (17 = 654). Strong national differences are identified. A quadratic relationship between age and CSM total score was apparent in the Australian data with a downward trend after age 35 yrs. There was no age effect in air), sample in the range from 18 to 29 yrs. Factor analysis identified a three-factor solution in all groups for both men and women. Tucker's congruence coefficients indicate that: (1) this solution is highly congruent between sexes in each culture, and (2) a morning affect factor is highly congruent between cultures. These results indicate there are national differences in factorial structure and that cut-off scores used to categorize participants as morning- and evening-types should be established for different cultural and age groups.

Background: The Functional Capacity Index (FCI) was designed to predict physical function 12 months after injury. We report a validation study of the FCI. Methods: This was a consecutive case series registered in the Queensland Trauma Registry who consented to the prospective 12-month telephone-administered follow-up study. FCI scores measured at 12 months were compared with those originally predicted. Results: Complete Abbreviated Injury Scale score information was available for 617 individuals, of whom 587 (95%) could be assigned at least one FCI score (range, 1-17). Agreement between the largest predicted FCI and observed FCI score was poor (kappa = 0.05; 95% confidence interval, 0.00-0.10) and explained only 1% of the variability in observed FCI. Using an encompassing model that included all FCI assignments, agreement remained poor (kappa = 0.05; 95% confidence interval, -0.02-0.12), and the model explained only 9% of the variability in observed FCI. Conclusion: The predicted functional capacity poorly agrees with actual functional outcomes. Further research should consider including other (noninjury) explanatory factors in predicting FCI at 12 months.

Recent analyses assert that large marine vertebrates such as marine mammals are now 'functionally or entirely extinct in most coastal ecosystems'. Moreton Bay is a large diverse marine ecosystem bordering the fastest growing area in Australia. The human population is over 1.6 million and increasing yearly by between 10% and 13% with resultant impacts upon the adjoining marine environment. Nonetheless, significant populations of three species of marine mammals are resident within Moreton Bay and a further 14 species are seasonal or occasional visitors. This paper reviews the current and historical distributions and abundance of these species in the context of the current management regime and suggests initiatives to increase the resilience of marine mammal populations to the changes wrought by the burgeoning human population in coastal environments.
