In this book Jonathan Sperber deploys his extensive knowledge of nineteenth‐century European social and political history, and his diligent research into sources that have become readily available only recently, to produce a substantial biography of Karl Marx. We find, however, that Sperber is mistaken in his treatment of Marx's ideas and of the intellectual contexts within which Marx worked. In fact, we suggest that he is systematically mistaken in this regard. We locate a root source of the error in his reductive approach to theoretical ideas. In section I we focus on the claim, taken for granted in the book, that Marx's ideas are instantiations of “materialism.” By detailed reference to the record of Marx's writings, we show that there is no justification for describing Marx as a “materialist” in the usually accepted senses of that term. In section II we review how Soviet and other interpreters of Marx, taking their lead from the later Engels, insisted that “materialism” was fundamental to Marxism. We suggest that Sperber's presentation of Marx's thinking as “materialist and atheist” aligns far better with such interpretations than it does with what Marx actually wrote. In sections III and IV we criticize Sperber's “contextualist” approach to dealing with ideas in history. His approach may seem reminiscent of Quentin Skinner’ s, but where Skinner deploys the discursive conventions prevailing in a past time to illuminate theoretical ideas, Sperber reduces theoretical ideas to context. We name Sperber's approach “theoretical nominalism,” a term that we use to denote the view that theoretical ideas are nothing but interventions into particular situations. We end by suggesting that greater attentiveness to philosophy and theory would have enriched Sperber's efforts in this book.  相似文献

Ordinary iron objects from an ancient habitation site at Junnar in India, dating to the 2nd BC to AD 2nd century, were examined for their microstructure, chemical composition and age. The objects were mostly made of high carbon steel with a homogeneous microstructure consisting of fine spherical particles of carbide in the ferrite background, free of non-metallic inclusions. Their carbon concentration ranged from 0.7% to over 1.6% with one exception at 0.2%. Some of them contained trace amounts of silicon, manganese and sulfur while one object retained cavities due to volume contraction during solidification reactions. These features indicate that the objects examined constitute an early example of Indian steel making in crucibles. Evidence was found that basic techniques needed for the success of crucible steel technology were mostly available at Junnar at the time. The radiocarbon measurement on carbon samples extracted from one of the iron objects placed its date between 176 BC and AD 20, in agreement with the radiocarbon dates of three charcoal samples from the same site. The forgoing results support that crucible steel was produced in India at a much earlier date than previously supposed, to serve as a material for specific needs arising in daily life.  相似文献

Park, T. & Fitzgerald, E.M.G. September 2012. A late Miocene–early Pliocene Mihirung bird (Aves: Dromornithidae) from Victoria, southeast Australia. Alcheringa 36, 427–430. ISSN 0311-5518.

An incomplete tarsometatarsus identified as an indeterminate species of Dromornithidae is described from the upper Miocene–lower Pliocene shallow marine Black Rock Sandstone at Beaumaris, Victoria, Australia. This isolated specimen represents one of the few pre-Pleistocene dromornithids with a well-constrained geologic age. Additionally, it is one of the few pre-Quaternary dromornithid fossils recorded from southeast Australia. Comparisons with known dromornithid taxa suggest that the Beaumaris dromornithid is distinct from previously established species. This hitherto unknown species of dromornithid in the late Neogene of southeastern Australia cautions against deriving evolutionary patterns solely on the basis of fossils from northern Australia.  相似文献

As is widely recognised, fossil florules are difficult to correlate because they appear to have been more controlled by environmental and ecological factors than uniform changes which reflect the passage of geological time. Here I present a worked example of a generally applicable approach to this problem in dating and mapping fossil plant associations.

Floral associations are best described and named by the classical methods of phytosociology. The three dimensional shape of an association in rocks and its palaeoecology can then be critically assessed. For example, during Middle Triassic time the following plant associations would have been encountered on a traverse from the coast to several hundred kilometres inland from the Pacific margin of Gondwanaland: Pachydermophylletum (mangrove scrub), Linguifolietum (coastal swamp woodland), Dicroidietum odontopteroidium (floodplain forest), Phoenicopsetum (levee bank scrub), Dicroidietum odontopteroidium xylopterosum (xerophytic woodland) and Johnstonietum (mallee-like woodland).

The fourth dimension of fossil plant associations (time) is best assessed from the evolution of a prominent group of plants. In conjunction with the ranges of other plant megafossils, evolutionary changes can be used to define Oppel-zones. For the Late Permian to Early Jurassic of eastern Australasia, I have used the evolution of Dicroidium and leaves of related pteridosperm plants together with other species of restricted stratigraphic range or prominent in the definition of the fossil plant associations. From this evidence four Oppel-zones can be recognised. ‘Thinnfeldia’ callipteroides Oppel-zone (Chhidruan to Smithian, 250–230 × 106 years), Dicroidium zuberi Oppel-zone (Smithian to Middle Anisian, 230–220 × 106 years), D. odontopteroides Oppel-zone (Late Anisian to Ladinian, 220–210 × 106 years) and Yabeiella Oppel-zone (Carnian to Rhaetian, 210–200 × 106 years.

In a complete revision of the pteridosperm form-genera Dicroidium, Johnstonia and Xylopteris, a large number of new combinations and the following new taxa are proposed; Dicroidium gouldii sp. nov., D. odontopteroides var. argenteum var. nov., D. odontopteroides var. moltenense var. nov., D. radiatum sp. nov., D. townrovii sp. nov. and Johnstonia coriacea var. obesa var. nov.  相似文献

The US–Republic of Korea (ROK) alliance had significantly developed asset specificities and common social identities attached to it during the cold war period. If institutional features and ideational factors originating from the cold war threat can account for alliance resilience in the post-cold war period, the US–ROK alliance should be a ‘most likely case’ to support those causal links. This article shows that such is not the case. This article, instead, argues that the US–ROK alliance went beyond being an instrument of threat response to becoming a more complicated mechanism for serving ‘general interests’ in relation to North-East Asian regional order maintenance and order-building, which drove the US–ROK alliance between 1998 and 2008.  相似文献

In this study we analyse the spatial distribution patterns of professionals and related workers in high-skilled occupations and elementary workers in low-skilled occupations in the Seoul metropolitan area and explore their geographical factors. Spatial autocorrelation relates to the formation and clustering of hot spots according to each occupational characteristic. Geographic factors affecting the distribution of workplaces and residences in professionals-related occupations and elementary-related occupations act differently for each middle occupational classification. However, some occupations show similar spatial distribution patterns. In particular, we found that industrial economic drivers have influence more significant than other regional factors in determining the distribution of workplace and residence by occupation. The spatial coefficient of geographical adjacency varies with the attributes of each occupation and tends to be larger in professional jobs. Findings from the study will help prepare policies related to local talents for specialisation and advancement of the occupational structure and will be of wider interest.  相似文献

Lavishly decorated wagons excavated from royal Xiongnu burials are generally regarded as tribute items from China offered to Xiongnu elites, symbolizing important political and economic interactions between the Xiongnu state (209 BC–155 AD) and the Han dynasty (206 BC–220 AD). This theory views such vehicles as having no relation to indigenous Xiongnu craftsmanship. Furthermore, specialized products delivered to the northern nomadic peoples from the Han state are often cited in support of the notion of Xiongnu dependency on foreign states for technological and political development. Expecting to find evidence of China’s traditional iron and bronze technology, we examined a number of key metallic components of these wagons excavated from the royal Xiongnu burial at Golmod 2 in central Mongolia, radiocarbon dated to 109 BC–AD 75. Surprisingly, the iron metallurgy in question was based primarily on the bloomery process while low tin bronze and arsenical copper alloys dominated the pertinent bronze production. These respective technological traditions are typical of Xiongnu manufacture but significantly different from traditional Han metallurgy. We interpret this evidence as suggesting the need for a more balanced evaluation of foreign influence on the rise and development of the Xiongnu state.  相似文献
