GRAEME APLIN 《The Australian geographer》1999,30(1):93-101
This commentary concentrates on the physical production of the Australian Geographer and developments of a related nature. As I cannot pretend to have read every paper published over the last 71 years, comment on content is very limited. I also wish to avoid overlap with already published retrospectives included in Volume 19, Number 1, and Volume 27, Number 1, of this journal. A full issue-by-issue index is included in Volume 30, Number 1, of the Australian Geographer (pp. 103-26): all major papers, but not some minor pieces, are listed. Some of the latter, when part of a series, are listed in Tables 1 to 4 in this commentary. A full alphabetical author index for the 71 years of the journal will be included in the next issue (July 1999) as Appendix B. 相似文献

OPINIONOpen‐minded Geographers: Their Potential Role in Integrated Adaptive Environmental Management
There are three key factors to be considered in comprehensive environmental management: (a) integration across disciplines and interests; (b) flexibility and adaptability based on feedback; and (c) interactions between policy and implementation at different scales. Successful management is both integrated and inclusive, and also adaptive and flexible. It involves a synthesis of work, requiring empathy among contributors and active synthesis. Furthermore, there is a need for a dialectical consideration of processes acting at various scales. Geographers who are not too narrowly specialised have a key role to play, and, collectively, might have been more centrally involved in environmental management than they have been. 相似文献

We describe a method which effectively and gently disaggregates muds and mudstones by combining a saturation-freeze-thaw technique with treatment by ultrasonic probe. The method works well for samples containing <5% TOC and which have been buried to depths less than about 3500 m. It does not work for samples strongly cemented with carbonates or silicates. Scanning electron micrographs of size fractions and the strong mineralogical segregation between size fractions are offered as evidence of complete disaggregation. 相似文献
