Twenty-four measurements were taken on five of the paired cranial bones and the otoliths of a modern sample of 177 blue cod. Parapercis colias. Regression analysis was performed on these measurements to estimate live fork length and ungutted weight. A number of regression models were examined (linear, logarithmic, exponential and power curve) to work out the optimum estimator for each bone measurement. It was found that live fork length of this species can be estimated with a standard error of less than ±28 mm, and the weight to less than ±140 g. Coefficients are provided for 48 equations linking bone size to live characteristics. This is followed by a study of blue cod from an archaeological site at Waihora in the Chatham Islands. Measurements were made on 8036 archaeological bones with a minimum number of individuals of 2547. It was found that the blue cod catch had near normal characteristics, with a mean fork length of 327 mm and SD of 57 mm. The mean body weight was estimated at 569 g. The usable meat weight represented by these fish is estimated to be 1.0 t. © 1997 John Wiley & Sons, Ltd.  相似文献

Thelodont scales and associated fragments of conodont elements identified as Turinia sp. cf. Turinia australiensis and Ozarkodina sp. cf. Ozarkodina buchanensis respectively are described for the first time from the Early Devonian Murray Creek Formation of Reefton, New Zealand. The conodont and thelodont components of the fauna suggest a late Pragian to early Emsian age for the assemblage.  相似文献

Abstract In early 1919, people like Hu Shi and Chen Duxiu were regarded as members of an ivory-tower "academic faction" (xuepai), embroiled in a debate with an opposing "faction." After the May Fourth demonstrations, they were praised as the stars of a "New Culture Movement." However, it was not obvious how the circle around Hu Shi and Chert Duxiu was associated with the May Fourth demonstrations. This link hinged on the way in which newspapers like Shenbao reported about the academic debates and the political events of May Fourth. After compartmentalizing the debating academics into fixed xuepai, Shenbao ascribed warlord-political allegiances to them. These made the Hu-Chen circle look like government victims and their "factional" rivals like the warlords' allies. When the atmosphere became hostile to the government during May Fourth, Hu Shi's "faction" became associated with the equally victimized May Fourth demonstrators. Their ideas were regarded as (now popular) expressions of anti-government sentiment, and soon this was labeled the core of the "New Culture Movement." The idea and rhetoric of China's "New Culture Movement" in this way emerged out of the fortuitous concatenation of academic debates, newspaper stories, and political events.  相似文献

Since at least the 1960s, the importance of the tremendous territorial expansion under Qing role to the modem history of China has been generally acknowledged. Indeed, one can say that the frontier story is one of the things that makes the Qing "Qing." However, only in the last twenty years has the study of what is now termed the "borderlands" come into its own as a sub-field. This essay begins by describing some key concepts and terms in the study of the Qing frontier, including the Manchu wordjecen. It then raises the problem of narrative fiameworks, asking how we might best contextualize the growth of the empire, before going on to explore the implications of the discursive shift represented by the "New Qing History" and the extensive research on Qing borderlands associated therewith. A poem by the Mongol poet Na-xun Lan-bao provides the focus for a concluding discussion of a distinctive Qing frontier sensibility.  相似文献

作为史学发展进程中一种带有规律性的史学现象的新史学,是历史学发展的内在要求和历史学者的永恒追求。史学史表明,历史学的发展历程,在本质上就是一个一代一代的历史学者在传承既有史学文化遗产的基础上追求新史学的永无止境的过程。历史学者对新史学的追求,是历史学者史家主体意识的鲜明而集中的体现。历史学者所追求的新史学,虽有明确的方向性,但一般只是一个模糊的轮廓。正是通过、并且正是在历史学者对新史学孜孜不倦的永恒追求中,史学不断实现着对自身的超越。  相似文献
