Societies with low-level food production economies occupy the vast and diverse middle ground between hunting–fishing–foraging and agriculture. Efforts by Ford, Harris, Rindos, Zvelebil, and others to characterize this in-between territory are discussed, and a new conceptual framework is proposed. Domestication, the central landmark of this middle ground, is situated well away from the boundaries with hunting–gathering and agriculture, and separates low-level food production economies into two broad categories. Key issues and questions concerning societies with low-level food production, both with and without domesticates, are discussed. Hunter–gatherer and agriculture boundary zones on either side of the middle ground are considered, as are the developmental pathways that traverse them. 相似文献

Educated citizens are often considered more likely to report corruption; this belief shapes anti-corruption campaigns. However, we know little about how other factors may interact with education’s impact on willingness to report corruption. This article examines data from a household survey undertaken in Papua New Guinea. We find considerable support for the notion that education encourages a greater willingness to report various types of corruption to officials. While our results indicate that this is especially the case when respondents believe that corruption would be addressed by the government, they also show that secondary and post-secondary levels of education can have a positive impact even among those who do not have much faith in reporting institutions. However, the results also suggest that academics and policy-makers should be sensitive to the way trust in the state impacts educated citizens’ willingness to report different kinds of corruption. 相似文献

Thirty ammonite taxa are recognised in the Wangarlu Mudstone of the Bathurst Island Group from the Cox Peninsula and Shoal Bay, Northern Territory, Australia. Included are a new heteromorph genus Notostreptites, type species N. exilis, and four additional new species and subspecies: Pseudhelicoceras gracilis, Labeceras (L.) tumidum, Labeceras (Appurdiceras) decorum, and Idiohamites dorsetensis laticostatus. The assemblage is best collectively correlated with the Mortoniceras (M.) inflatum Zone of the standard European Albian zonation but some of its members may represent the lower part of the Stoliczkaia dispar Zone. It is broadly correlative with faunas from the Eromanga Basin, which relate to an extensive eastern Australian Late Albian epicontinental sea, but is strikingly different in aspect. The Wangarlu Mudstone assemblage has relatively high diversity and an abundance of cosmopolitan heteromorph taxa well known from Europe and elsewhere, whereas Eromanga Basin assemblages are of relatively low diversity and dominated by Austral heteromorph genera known only from Australasia, southern Africa and Malagasy. The Austral character of Eromanga Basin assemblages is attributed to evolution in a restricted epicontinental sea environment and modest dispersal whereas the continental margin position of the Wangarlu Mudstone ensured an influx of pandemic elements drawn from the mid-Cretaceous world ocean. 相似文献
