Management of isolated orbital floor blow-out fractures: a survey of Australian and New Zealand oral and maxillofacial surgeons

Background: This is the first report of involvement of Australian and New Zealand oral and maxillofacial surgeons in the management of isolated orbital floor blow-out fractures and was conducted to obtain comparisons with the results from a recent similar survey of British oral and maxillofacial surgeons. Methods: A questionnaire survey was sent to all 113 practising members of the Australian and New Zealand Association of Oral and Maxillofacial Surgeons in April 2002 with a second mailout 1 month later. Results: Sixty-nine per cent of the respondents were referred isolated orbital floor blow-out fractures for manage-ment, and just over half of these respondents estimated that 50% or more of the cases went to surgery. The materials most commonly used in orbital floor reconstruction were resorbable membrane for small defects and autologous bone for large defects. Conclusion: As in Britain, management of isolated orbital floor blow-out fractures comprises part of the surgical spectrum for many oral and maxillofacial surgeons in Australia and New Zealand. The management protocol was observed to be very similar between the two groups.

Corporate governance codes in Australia and New Zealand: Propriety and prosperity

Overview of the central features of corporate governance codes, 'Principles of Good Corporate Governance and Best Practice Recommendations' (released by the ASX Corporate Governance Council) and 'Corporate Governance in New Zealand, Principles and Guidelines' (released by New Zealand Securities Commission) - whether the codes address the right problem - are the solutions of independence and disclosure conceptually and practically viable - whether codes pay sufficient attention to wealth creation.

Mental health recovery and occupational therapy in Australia and New Zealand

Every individual with mental illness has the right to be safe and cared for. Most people will receive the love and care from their families and friends, but they will also expect mental-health professionals, occupational therapists and the community to work together to provide the necessary services to support their recovery from mental illness. This article highlights the development of the recovery approach for people with mental illness in Australia and New Zealand. The implications of recovery concepts for occupational therapy, in the areas of individualized approach, participation of service users and carers, person-centred assessment and intervention, intersectoral links and mental-health promotion, are discussed. There are a number of key areas requiring further research and debate, notably the most effective means of implementing and evaluating recovery-focused interventions.

Perceptions of marketing journals by senior academics in Australia and New Zealand

Increasingly, business schools are under pressure to produce quality outputs, including high quality international refereed journal publications. Understanding senior Australian and New Zealand marketing academics' views of journal quality is valuable to individual scholars and to the marketing discipline. This paper presents the findings of a study of such perceptions provided by senior academics in Australia and New Zealand. A survey containing a comprehensive list of 73 journals was sent to all professorial members of ANZMAC and Heads of Marketing Schools in Australia and New Zealand, with an overall response rate of 45%. Respondents rated the journals on a 5-point quality scale and means of ratings were used to establish overall rank. The results suggested that, while senior faculty in Australia and New Zealand have their own distinct perceptions of journal quality, these views are not inconsistent with international views. The implications of the results and directions for future research are discussed.

Evidence-based practice and rehabilitation: occupational therapy in Australia and New Zealand experiences

Evidence-based practice has become the dominant paradigm in the delivery of rehabilitation programme. However, occupational therapists in Australia and New Zealand have been slow in making the transition to become evidence-based practitioners. Collaboration between the university/ tertiary institute and clinical setting is one way that clinicians can be assisted with incorporating research into their practice. Two case examples are presented outlining how collaborative practice can result in improved out.. comes for all concerned.

Early-Middle Jurassic stratigraphy of the Fortrose-Chaslands region, southernmost South Island, New Zealand

The 40 km of coastline from Fortrose to Chaslands Mistake (southeastern South Island, New Zealand) comprises sediments that are part of the Early-Middle Jurassic of the Murihiku Terrane. The sediments are dominantly fluvial with some marine beds and alluvial fan deposition, and display an evolution of fluvial style which progresses from perennial flow to seasonal flow. The McPhee Cove Conglomerate is a prominent unit to the north. It has been used to separate two formations which would otherwise, on inherent lithological grounds, be difficult to distinguish. This paper discusses several similar conglomerates which occur in the south, but which are separated from the type area of the McPhee Conglomerate by major tectonic disruption. Hence, the existing lithostratigraphic nomenclature to the north, including the McPhee Cove Conglomerate, cannot be simply extended southwards. The Fortrose-Chaslands area appears to consist of two tectonic blocks, the Slope Point Block and the Brothers Block, which are separated from each other and from the adjacent Papatowai Block by major strike faults (or fault zones). A change is proposed to the existing stratigraphy which involves recognising all terrestrial sediments as part of the False Island Formation. Four prominent clast-supported conglomerate horizons are named as members of the False Islet Formation: the White Head Conglomerate, Black Bluff Conglomerate. Hoiho Conglomerate, and Slope Point Conglomerate Members. The latter contains five named conglomerate beds.

Adult-population incidence of severe sepsis in Australian and New Zealand intensive care units

Objective. To determine the population incidence and outcome of severe sepsis occurring in adult patients treated in Australian and New Zealand intensive care units (ICUs), and compare with recent retrospective estimates from the USA and UK. Design. Inception cohort study. Setting. Twenty-three closed multi-disciplinary ICUs of 21 hospitals (16 tertiary and 5 university affiliated) in Australia and New Zealand. Patients. A total of 5878 consecutive ICU admission episodes. Measurements and results. Main outcome measures were population-based incidence of severe sepsis, mortality at ICU discharge, mortality at 28 days after onset of severe sepsis, and mortality at hospital discharge. A total of 691 patients, 11.8 (95% confidence intervals 10.9-12.6) per 100 ICU admissions, were diagnosed with 752 episodes of severe sepsis. Site of infection was pulmonary in 50.3% of episodes and abdominal in 19.3% of episodes. The calculated incidence of severe sepsis in adults treated in Australian and New Zealand ICUs is 0.77 (0.76-0.79) per 1000 of population. 26.5% of patients with severe sepsis died in ICU, 32.4% died within 28 days of the diagnosis of severe sepsis and 37.5% died in hospital. Conclusion. In this prospective study, 11.8 patients per 100 ICU admissions were diagnosed with severe sepsis and the calculated annual incidence of severe sepsis in adult patients treated in Australian and New Zealand ICUs is 0.77 per 1000 of population. This figure for the population incidence falls in the lower range of recent estimates from retrospective studies in the U.S. and the U.K.

Australia and New Zealand applied linguistics (ANZAL): Taking stock

This paper reviews some emerging trends in applied linguistics in both Australia and New Zealand. It sketches the current scene of (selected) postgraduate applied linguistics programs in higher education and considers how various university programs define applied linguistics through the classes (titles) they have postgraduate students complete to be awarded a degree. Evidence of program requirements and topics reveal not only what applied linguistics generally entails, but offers insights into how applied linguistics is defined and practiced. Additionally, some of the salient research topics (titles) being published in the journals from the two countries' applied linguistics associations are sketched.

Speleothem master chronologies: combined Holocene O-18 and C-13 records from the North Island of New Zealand and their palaeoenvironmental interpretation

The stable isotope records of four stalagmites dated by 19 TIMS uranium series ages are combined to produce master chronologies for delta(18)O and delta(13)C The delta(18)O records display good overall coherence, but considerable variation in detail. Variability in the delta(13)C records is greater, but general trends can still be discerned. This implies that too fine an interpretation of the structure of individual isotopic records can be unreliable. Speleothem delta(18)O values are demonstrated to show a positive relationship with temperature by comparing trends with other proxy records, but also to respond negatively to rainfall amount. Speleothem delta(13)C is considered to be most influenced by rainfall. The postglacial thermal optimum occur-red around 10.8 ka BP, which is similar in timing to Antarctica but up to 2000 years earlier than most Northern Hemisphere sites. Increasingly negative delta(18)O values after 7.5 ka BP indicate that temperatures declined to a late mid-Holocene minimum centred around 3 ka BP, but more positive values followed to mark a warm peak about 750 years ago which coincided with the 'Mediaeval Warm Period' of Europe. Low 5110 values at 325 years BP suggest cooling coincident with the 'Little Ice Age'. A marked feature of the delta(13)C record is an asymmetric periodicity averaging c. 2250 years and amplitude of c. 1.9parts per thousand. It is concluded that this is mainly driven by waterbalance variations with negative swings representing particularly wet intervals. The 5110 record shows a higher-frequency cyclicity with a period of c. 500 years and an amplitude of c. 0.25 parts per thousand. This is most likely to be temperature-driven, but some swings may have been amplified by precipitation.
