While screen production is notoriously centralised, it is still found outside major media cities where the central problem for actors in these subordinate media cities is how to create sustainable levels of screen production capabilities in circumstances of increasing centralisation and globalisation in media production and its design. This article discusses how the screen production sectors of two subordinate media cities, Brisbane and the Gold Coast, are organised. Each city represents a different pathway for the sustainability of a media sector. The Gold Coast is a production location for globally and nationally dispersed high-budget feature film and TV drama production; while Brisbane is mostly a ‘national production’ location for domestically oriented news, documentary, infotainment and sports programming with a focus on lower budgeted feature filmmaking and occasionally, television drama. These different city pathways are the product of the creative resources and infrastructure evident in each city. 相似文献

This study explores the relationship between Tortuguero National Park and Tortuguero, a neighboring village in northeastern Costa Rica. Based largely on a household survey, the study considers the effect of the establishment of the park on the subsistence and commercial economies of Tortuguero. It also considers the impact of park-based tourism and its potential role in the economic development of the community. Survey results indicate a general decline in the village's standard of living in the decade since the park was created, but an increase in nature tourism has somewhat offset the decline in commercial resource exploitation. Increased participation by villagers in park-based tourism appears to offer hope for sustainable economic development. 相似文献

This article evaluates Karl Popper's contribution to analytic philosophy, and outlines some of the contradictions in his work which make it difficult to locate in any particular tradition. In particular, the article investigates Popper's own claims to be a member of the rationalist tradition. Although Popper described himself as a member of this tradition, his definition of it diverged quite radically from that offered by other supporters of rationalism, like, for example, Mach, Carnap, and the logical positivists of the Vienna Circle. The reason for this was that Popper believed the rationalist tradition, if it were to remain coherent and relevant, needed to overcome the dilemma posed by Hume's problem of induction. Popper believed that this problem rendered conventional understandings of rationalism, science, and inductive reasoning incoherent. This article suggests that Popper's principal contribution to modern philosophy was to reconfigure the rationalist tradition in such a way as to circumvent the problem of induction while preserving the rationalist commitment to reason, rational debate, and objective knowledge. Popper's reconfiguration of the epistemological bases of the rationalist tradition challenged dominant understandings of rationalist and analytic philosophy, and may be appropriately understood as part of a wider move among philosophers like Quine and Putnam to challenge conventional understandings of analytic philosophy, and of what philosophy itself could and could not achieve. It also informed a vision of social and political life (and of the social and political sciences) as rooted in principles of freedom, equality, and rational debate, but which cannot be fit within the traditional ideological landscape. 相似文献

Since being excavated in 2003, the skull of LB1 (the holotype of Homo floresiensis) has been given many faces, though the details regarding how each was accomplished are typically few. Here we detail our application of known, and verified, relationships between the skull and soft tissues of anatomically modern humans to produce an evidence-based facial approximation of LB1. We then compare our results to nine pre-existing LB1 faces using geometric morphometrics. These analyses suggest our facial approximation differs in proportional facial width, upper lip height and nasal morphology. Some of these differences are likely due to a different interpretation of taphonomic and excavation damage, application of different 'forensic' methods and/or an idiosyncratic incorporation of aspects of non-human primate morphology. Other differences, and in particular upper lip height, are less justifiable in relation to the skeletal evidence. 相似文献

Dermal denticles of two thelodont agnathans, Australolepis seddoni gen. et sp. nov., and a possible nikoliviid gen. et sp. indet. are described from the Gneudna Formation, a marine sequence of interbedded limestone and shale exposed on the eastern edge of the Carnarvon Basin, Western Australia. The age and significance of these new forms are discussed. The Gneudna Formation is Late Devonian, probably early Frasnian, which, if confirmed, makes these the youngest thelodonts known to date. 相似文献
