A new genus and species of Prophalangopsidae, Hylophalangopsis chinensis gen. and sp. nov., is described here on the basis of one well-preserved complete fore wing from the Paleocene of Northern Tibet. The differences between this species and other described species, its systematic position, and its evolutionary significance are discussed. 相似文献

This study empirically analyzes the influence of school accessibility on student academic achievement in a rural area of Taiwan. The sample population comprised elementary and junior high-school students in Pinlin, a small village outside Taipei City, the capital of Taiwan. Data were obtained through a questionnaire survey and analyzed via linear regression and ordered logit regression for continuous grade point average and discrete letter grade, respectively. Compared with previous research, this study presents the following new findings: (1) similar to elementary-school children, travel obstacles also negatively affected learning achievement of junior high-school adolescents; (2) travel obstacles affected academic achievement more significantly for adolescents than children; and (3) travel obstacles affected letter grades more significantly than grade point averages in children. The empirical evidence indicates that travel obstacles explain the academic achievements of children and adolescents with moderate or weak significance. 相似文献

AbstractOnce ostracized and relegated to a mere marginal position in the history of modern Chinese literature, Lin Shu 林紓 (1852–1924) has now become an important and relatively well-known figure. This paper summarizes existing research on Lin Shu's translations and the controversy between the vernacular and the classical language, emphasizing the achievements of Chinese and Japanese scholarship during the past century. For practical reasons, results have been divided chronologically into four categories: (1) Criticism of Lin Shu before 1924; (2) Early Chinese Scholarship (1924–1935); (3) Late Chinese and Early Japanese Scholarship (1935–1960); (4) Renaissance of Studies on Lin Shu outside China (1960–2000). This periodization is supplemented with a brief excursus on the current state of Lin Shu studies. 相似文献

Lithic researchers rely heavily on experimentation to infer past behaviors and activities based on stone artifacts. This paper explores the analogical nature of archaeological inference and the relationship between experimental design and inference validity in stone artifact experimentation. We show that actualistic flintknapping lacks vital aspects of scientific experimentation, and thus has inherent inferential issues of analogical adequacy and confidence. It is argued that a greater emphasis on hypothesis construction and variable control is needed in order to establish sound referential linkages upon which constructive analogic inferences about the past can be built. 相似文献

The Belt and Road Initiative (BRI) is widely touted as China's answer to development through international connectivity. The scheme has often been linked to China's objectives of crafting a new world order centred on itself and/or stabilizing its economy through externalizing surplus capacity. While important in broadly framing China's relationship with the world, this article posits that such a fixation on state-centric visions of development leaves the door open for misinterpretation, mistaking the BRI for a coherent set of projects imposed ‘from above’. Delving into the execution of infrastructure planning on the ground, this article argues that taking a practice-oriented approach to large-scale developmental schemes can more accurately shed light on their internally fractured processes. Two airport projects in central China branded as part of the country's ‘aerial Silk Roads’ are examined to illustrate these dynamics, with particular attention paid to the airports’ shifting conceptualizations, the competitive motivations behind their (re)construction, and the social relations sustaining them. The authors argue that closely tracking the unfolding of a range of infrastructure planning practices within specific projects can demystify modern-day developmental programmes like the BRI, by revealing how their ‘grand’ visions are often reinterpreted, altered and frustrated at local levels, even before they have a chance to influence the world. 相似文献

氧化铁在钧瓷天蓝、天青系列釉色中的着色作用以及乳光蓝色问题,一直是学术界争论的焦点。本研究通过放大氧化铁含量的实验验证方法,通过SEM(scanning electron microscope-扫描电子显微镜)、EDS(Energy Dispersive Spectrometer-能谱仪)、XRD(X-ray diffraction-X射线衍射)等分析方法,重点研究了基础组成和分相结构对釉中氧化铁呈色的影响。同时,作者通过验证研究得出,钧瓷天蓝、天青系列釉色中,真正起呈色作用的是釉中的氧化铁等着色剂,第二相微粒散射呈色并非钧釉的普遍现象,或只是辅助呈色作用。 相似文献

汉武帝取得平定南越的胜利后,于元封元年(公元前110年)在海南建立珠崖郡和儋耳郡,实现了汉代中央直接对海南的统治和治理,在海南历史上具有划时代的意义。儋耳郡在汉昭帝始元五年(公元前82年)并入珠崖郡。但到西汉元始三年(公元前48年),汉元帝宣诏罢珠崖郡,至此珠崖郡短暂的历史结束。西汉王朝在统治和治理珠崖郡中付出一定的军事和经济代价, 相似文献

关于李自成铸币问题,我曾撰写《李自成铸“永昌通宝”》(1985年《陕西金融·钱币专辑〈4〉》)和《李自成铸“永昌通宝”再探》(《中国钱币》1990年4期)二文。十余年来,随着资料的不断补充和出土钱币的大量涌现,使我对李自成铸币在认识上有了进一步的提高,并有许多新的发现,因此,有再度深入探讨的必要。本文结合近十年来全国出土永昌钱的原始资料,确定版式和铸地,再结合钱文发展情况,参照其他大顺文物,确定各类版式的铸造时间,最后对李自成的货币政策做一些分析,力图比较全面地介绍李自成铸币过程,不妥之处请方家指正。 一、永昌通宝全国… 相似文献

Ground-edged artifacts were an important part of the Australian Aboriginal toolkit. They had practical day-to-day uses, but some had symbolic and social values that led to their movement across great distances. Australian provenance studies document long-distance Aboriginal exchange systems extending over hundreds of kilometers. The size and complexity of exchange systems and social networks were contingent upon resources and the productivity of a region's environment. Along the fertile, well-watered lands east of the Great Dividing Range, movement of objects may have been geographically more circumscribed than in drier areas to the west. One hundred and twenty-one mafic, ground-edged artifacts from the New South Wales (NSW) Central Coast and 368 geological specimens from potential sources were non-destructively analyzed by portable X-Ray fluorescence spectrometry. Results indicate the existence of a well-used basalt source within the region at Peats Ridge-Popran Creek as well as multiple local and non-local sources up to 430?km from Mangrove Mountain on the NSW Central Coast. 相似文献
