ODP Leg 182 drilled two north–south transects in the western Great Australian Bight close to longitude 128°E. These transects penetrated a remarkably thick section of uppermost Pliocene and Pleistocene carbonate sediments, which are separated from Miocene sections by a major hiatus. In the eastern transect, at sites 1129, 1131 and 1127, the Brunhes–Matuyama boundary (onset of C1n) was found at 343 m, between 280 and 300 m, and at 343 m below the sea floor, respectively. In the western transect, at sites 1132 and 1130, it was found between 170 and 181 m, and at 200 m, respectively. Within the Brunhes chron, inclination and intensity fluctuations and correlations between susceptibility and standard δ18 O records were used to give age–depth relations. These age relations from the palaeomagnetics are broadly consistent with the biostratigraphy and the δ18 O results from Leg 182, but do not provide an entirely independent dataset. Rock magnetism stratigraphy at site 1131 revealed the principal bryozoan buildup to be at the time of the last glacial lowstand, as suggested by previous workers. At all sites the sedimentation rate increases from the basal unconformity up into the thick Upper Pleistocene section. In the western transect there appears to be a partial record of most of the Late Pliocene and Early Pleistocene chron boundaries (C1r1n to C2An3n) in a condensed section, but in the eastern transect only the Jaramillo (C1r1n) is observed.

Aim: This pilot study aimed to evaluate the knowledge and practices of South Australian radiographers regarding lateral elbow repositioning and to determine whether an educational poster could improve repositioning knowledge., Method: The study was undertaken in four stages. Stage one involved the development of a survey to explore radiographer knowledge and practices surrounding lateral elbow repositioning. Stage two involved the development of an educational poster. Stage three was a pilot validity study. Three participants (n = 3) were involved in testing the validity and test-retest reliability of the survey and the poster. Stage four was the interventional study which involved the distribution of surveys to two radiography departments in South Australia on two occasions, before and after the distribution of the poster. Six complete data sets were analysed., Results: The pilot validity study ensured the test-retest reliability of the survey was strong (P = .629). It was determined that an educational poster made no significant difference to the knowledge of lateral elbow radiograph repositioning among radiographers (P = .253). It was indicated that this result was not due to familiarity with the presurvey questions (P = .171). Thematic analysis of the open discussion questions found that most participants found the poster helpful but did not consider repositioning to be difficult. The introduction of the poster did not increase image repeat rate and the poster was used moderately over the study length., Conclusion: As this study was unable to determine whether a poster could improve the knowledge and practices of lateral elbow repositioning among radiographers, further research is needed., (Copyright © 2019.

Objective: To test a management model of facilitated reflection on network feedback as a means to engage services in problem solving the delivery of integrated primary mental healthcare to older people., Design: Participatory mixed methods case study evaluating the impact of a network management model using organisational network feedback (through social network analysis, key informant interviews and policy review)., Intervention: A model of facilitated network reflection using network theory and methods., Setting: A rural community in South Australia., Participants: 32 staff from 24 services and 12 senior service managers from mental health, primary care and social care services., Results: Health and social care organisations identified that they operated in clustered self-managed networks within sectors, with no overarching purposive older people's mental healthcare network. The model of facilitated reflection revealed service goal and role conflicts. These discussions helped local services to identify as a network, and begin the problem-solving communication and referral links. A Governance Group assisted this process. Barriers to integrated servicing through a network included service funding tied to performance of direct care tasks and the lack of a clear lead network administration organisation., Conclusions: A model of facilitated reflection helped organisations to identify as a network, but revealed sensitivity about organisational roles and goals, which demonstrated that conflict should be expected. Networked servicing needed a neutral network administration organisation with cross-sectoral credibility, a mandate and the resources to monitor the network, to deal with conflict, negotiate commitment among the service managers, and provide opportunities for different sectors to meet and problem solve. This requires consistency and sustained intersectoral policies that include strategies and funding to facilitate and maintain health and social care networks in rural communities., (Published by the BMJ Publishing Group Limited.
