AbstractSeafloor mounds are enigmatic features along many continental margins and are often interpreted as gas hydrate pingoes, seep deposits, mud volcanoes, or hydrothermal mounds. When such mounds occur in basins with past volcanic activities, they have the potential to host seafloor metalliferous deposits, which is generally overlooked. Using geophysical datasets, we document the fluid plumbing systems that promoted the formation of seafloor mounds in the Great South Basin (GSB), offshore New Zealand. We also investigate these mounds as potential seafloor metalliferous deposits. Our results reveal 9 seafloor mounds (~ 137 m high) above gigantic (~ 5.4 km high) fluid escape pipes that are associated with deeper crystalline rocks. The structural make-up of the mounds, their geospatial relationships with the pipes and intrusive rocks, and geophysical properties suggest a primary volcanic or hydrothermal origin for the culpable fluids and mounds respectively. Fluids derived from deeper coal beds and shallow foraminiferal oozes in the basin constitute secondary fluid sources focused along polygonal faults and lateral flow cells. A main sub-vertical and minor lateral fluid plumbing patterns are proposed. The relationship between the mounds, pipes, underlying intrusive rocks, and upward routing of mineral-rich fluids could have implications for the formation of ore-grade mineral deposits on the seafloor in the GSB.

This paper describes an international biosolids management initiative, known as the Australian and New Zealand Biosolids Partnership (ANZBP). The ANZBP - known formerly as the Australasian Biosolids Partnership – comprises 33 members dedicated to promoting the sustainable management of biosolids across the two nations. Two critical research projects are described, each of which contributes to the ANZBP goal of promoting the sustainable management of biosolids. The first is a review of community attitudes to biosolids management, the outcomes of which will be used to refine communication tools and methods of community consultation and which will provide input to policy development over time. The second is a review of regulations in place in Australia and New Zealand carried out to identify inconsistencies and improvements that could be made. An outcome of this initiative is potentially the development of a best practice manual. The relationship of the two projects to a sustainability framework adopted by the ANZBP is also described, as is the relationship of the two projects to each other.

The Relationship

Cyniclomyces guttulatus is usually recognised as an inhabitant of the gastrointestinal (GI) tract in rabbits. However, large numbers of C. guttulatus are often detected in the faeces of diarrhoeic rabbits. The relationship of C. guttulatus with rabbit diarrhoea needs to be clearly identified. In this study, a C. guttulatus Zhejiang strain was isolated from a New Zealand White rabbit with severe diarrhoea and then inoculated into SPF New Zealand white rabbits alone or co-inoculated with Eimeriaintestinalis, another kind of pathogen in rabbits. Our results showed that the optimal culture medium pH and temperature for this yeast were pH 4.5 and 40–42 °C, respectively. The sequence lengths of the 18S and 26S ribosomal DNA fragments were 1559 bp and 632 bp, respectively, and showed 99.8% homology with the 18S ribosomal sequence of the NRRL Y-17561 isolate from dogs and 100% homology with the 26S ribosomal sequence of DPA-CGR1 and CGDPA-GP1 isolates from rabbits and guinea pigs, respectively. In animal experiments, the C. guttulatus Zhejiang strain was not pathogenic to healthy rabbits, even when 1 × 108 vegetative cells were used per rabbit. Surprisingly, rabbits inoculated with yeast showed a slightly better body weight gain and higher food intake. However, SPF rabbits co-inoculated with C. guttulatus and E. intestinalis developed more severe coccidiosis than rabbits inoculated with C. guttulatus or E. intestinalis alone. In addition, we surveyed the prevalence of C. guttulatus in rabbits and found that the positive rate was 83% in Zhejiang Province. In summary, the results indicated that C. guttulatus alone is not pathogenic to healthy rabbits, although might be an opportunistic pathogen when the digestive tract is damaged by other pathogens, such as coccidia.

Abstract Background ICU-specific tables of antimicrobial susceptibility for key microbial species (‘antibiograms’), antimicrobial stewardship (AMS) programmes and routine rounds by infectious diseases (ID) physicians are processes aimed at improving patient care. Their impact on patient-centred outcomes in Australian and New Zealand ICUs is uncertain. Objectives To measure the association of these processes in ICU with in-hospital mortality. Methods The Australian and New Zealand Intensive Care Society (ANZICS) Adult Patient Database and Critical Care Resources registry were used to extract patient-level factors, ICU-level factors and the year in which each process took place. Descriptive statistics and hierarchical logistic regression were used to determine the relationship between each process and in-hospital mortality. Results The study included 799 901 adults admitted to 173 ICUs from July 2009 to June 2016. The proportion of patients exposed to each process of care was 38.7% (antibiograms), 77.5% (AMS programmes) and 74.0% (ID rounds). After adjusting for confounders, patients admitted to ICUs that used ICU-specific antibiograms had a lower risk of in-hospital mortality [OR 0.95 (99% CI 0.92–0.99), P = 0.001]. There was no association between the use of AMS programmes [OR 0.98 (99% CI 0.94–1.02), P = 0.16] or routine rounds with ID physicians [OR 0.96 (99% CI 0.09–1.02), P = 0.09] and in-hospital mortality. Conclusions Use of ICU-specific antibiograms was associated with lower in-hospital mortality for patients admitted to ICU. For hospitals that do not perform ICU-specific antibiograms, their implementation presents a low-risk infection management process that might improve patient outcomes.

The Relationship

In recent years workplace stress has been seen as an important occupational health and safety problem and probation officers in New Zealand have been identified as suffering from increasing perceptions of stress. Accordingly, the present study was undertaken with a sample of 50 New Zealand Probation Officers in three offices to examine the relationship of individual, organisational and work stressors with work related strains. It was predicted that work stressors would be positively related to strains and that individual differences (e.g., age or gender) would have a moderating effect on the relationship between stressors and strains. The results showed that stressors caused by organisational problems, such as role boundary and overload, were related to strains, more strongly than job content problems, such as difficult clients. Secondly, age may have a curvilinear relationship to strains. Thirdly, the office, or place of work, moderates the stressor strain relationship.

Objective: This review examines how psychiatric clinical supervision is represented in the psychiatric literature and its relevance for Australasian psychiatry. Method: The literature was first identified then reviewed using Medline and Psychlit, manual searches of relevant journals and personal contact with some key workers in Australia and New Zealand. Results: The predominantly American literature written two to three decades ago reflected the conditions in which psychiatry was practised at that time, largely based in asylums or private offices and informed by the dominant psychoanalytic discourse of that era. These articles, frequently anecdotal and with little empirical support, conceptualized supervision as a developmental process, a syndrome, or a process of identification. They focused substantially on the nature of the relationship between the trainee and supervisor. More recent writers have included trainees’ perspectives. They have identified a number of problems with supervision, including role conflicts, uncertainty about boundaries, lack of supervisory training and lack of effective feedback, and have introduced the concepts of adult learning as highly relevant. These concerns, however, have led to little change to date. Conclusion: The implementation by the Royal Australian and New Zealand College of Psychiatrists (RANZCP) of new training by-laws provides an opportunity to define the meaning of supervision in the current clinical context, to undertake research to clarify the key elements in the process, and to evaluate different techniques of supervision.
