It is not surprising that the organization and behaviour of farm organizations differ depending upon whether they operate in unitary or federal states or in parliamentary or congressional type environment. The question is how different or similar are they and their behaviour in states which are both federal and both parliamentary.

This article examines the variations between Australian and Canadian farm organizations and examines some of the possible explanations for them. Some of the differences stem from the origins of the organizations, others from variations in the two countries’ political institutions or their usages.  相似文献

A new macropodine genus and species, Silvaroo bila, is described from the Pliocene Chinchilla Sand of Queensland. The generic concept of Protemnodon is reviewed, and it is concluded that two Pliocene species previously placed in that genus (bandharr and buloloensis) belong in Silvaroo. Species of Silvaroo resemble the modern forest wallabies of Papua New Guinea (species of Dorcopsis and Dorcopsulus) and also bear close phenetic resemblance to the late Miocene Dorcopsoides fossilis. Forest wallabies are not known from mainland Australia after the middle Pliocene, but occur in the late Pliocene and Pleistocene of New Guinea.  相似文献

ABSTRACT

Medial moraines deposited by former glaciers and ice sheets are rare in Scotland. The most prominent example is the Sgriob na Caillich moraine, which consists of two to four parallel belts of angular quartzite boulders that extend northwestwards for over 3.5?km from the SW flank of Beinn an Oir on the Isle of Jura. The boulder belts extend to within 300?m of the present coastline, where they are truncated by a low bluff and raised marine terrace. The source of the moraine coincides with bedrock gullies and cliffs that represent the scars of former rock-slope failure(s), indicating that the moraine debris was sourced by one or more rockfalls or rockslides onto the ice surface after Beinn an Oir had emerged from the thinning ice cover as a nunatak. Exposure dating of boulders on the moraine indicate that it formed at 16.6?±?0.8?ka, consistent with the timing of ice-sheet retreat in this sector. The alignment of the moraine indicates ice-margin retreat to the SE; as regional ice-sheet retreat across the adjacent offshore shelf was to the NE, this anomaly implies that a residual icefield became stranded on Jura during ice-sheet retreat.  相似文献

Abstract

This paper describes some of the changes that affected the coastlines of South Uist and Benbecula following the ‘Great Storm’ of 11 January 2005. The paper considers historical changes in patterns of winter storminess and addresses the issue of whether or not there has been a recent increase in regional storminess, manifested partly by this particular storm. The paper concludes on the basis of available Greenland ice core chemistry data and historical climate data, together with recent meteorological data, that no such increase has taken place. This surprising conclusion is further discussed in relation to current thinking on the nature of recent climate change.  相似文献

Developing theories of vernacular architecture in archaeology has been hindered by the lack of a defined methodology for studying ancient buildings, and the absence of information on the mechanical properties of construction materials uncommon in today's building practices. In this paper we use Finite Element Methods and recent research on the structural properties of whalebone to analyze the architecture of Thule semi-subterranean houses. These unique dwellings were constructed and used by the ancestors of Inuit/Eskimo peoples in the Canadian Arctic and Greenland. Little is known about how they were designed and constructed because few have ever been discovered intact. The substantial weight of whalebone roof frames suggests that some designs would have performed better than others. Poorly planned houses, or the use of whalebone in a symbolic rather than strictly utilitarian capacity, may have resulted in higher maintenance costs, thereby shortening their anticipated use life. In extreme cases, errors in design, or the failure of materials may have caused dwellings to collapse, resulting in injuries or possibly even death. We demonstrate through this case study that Finite Element Methods constitutes an effective methodology for studying ancient buildings, with the proviso that more research is needed on the mechanical properties of building materials used in the past.  相似文献
