Construction of the avian skull, as demonstrated by direct magnifying microfocal radiography (Aves)
SummaryThe new microfocus X-ray technique works with X-ray sources smaller than 10 Μm in diameter. Thus, in contrast to conventional X-ray systems, it is possible to obtain direct magnifications with high spatial resolution, i.e., well-focused radiographs with better contrast and “depth of focus”. In this connection, specific construction principles of the avian skull are elucidated, comparing several bird groups. The typical pneumatization effects are demonstrated, as are other biologically important anatomical features, in particular those of the bills/beaks as related to mechanical demands.
Physical characteristics of modern microfocus x-ray tubes.
The focal spot size of four 0.3 mm. microfocus commercial x-ray tubes was measured at various kilovoltages and tube currents using a resolution method.The implications of the variations observed are discussed in relation to clinical magnification radiography.
Professional support in rural New South Wales: perceptions of new graduate occupational therapists.
OBJECTIVE
To explore the experiences of professional support among new graduates working in rural New South Wales, including the current availability of professional support and the impact of support levels on professional practice.


DESIGN
Qualitative, using semistructured face-to-face or telephone interviews.


SETTING
New graduate occupational therapists employed in public and private hospitals and community health services in rural New South Wales.


SUBJECTS
Nine new graduate occupational therapists within their first year of practice.


MAIN OUTCOME
A description of participant experiences of professional support and strategies to enhance the recruitment and retention of occupational therapists in rural areas.


RESULTS
Participants reported varied experiences of professional support and emphasised the importance of having access to a wide variety of resources. Participants highlighted that professional support could assist in developing independence and other skills. However, ultimately a lack of support resulted in decreased confidence and subsequent decreased job satisfaction among participants.


CONCLUSIONS
The findings suggest that greater effort should be directed to ensuring that all new graduates have access to professional support, including structured supervision, and that strategies be explored and adopted to ensure that this occurs.
