Starch grains analysis of stone knives from Changning site,Qinghai Province,Northwest China

Plant residues recovered from prehistoric stone artifacts can be used to help explain tool function and plant use. At the Changning site in Qinghai Province, Northwest China, dating from 4000 yr BP, we examined starch granules extracted from three slate stone knives. A total of 153 starch grains were retrieved from three stone knives, from which we identified starches from legumes, the Triticeae tribe, foxtail millet (Setaria italica), broomcorn millet (Panicum miliaceum), roots and tubers. These results indicate that the stone knives may have been used for a variety of activities that included reaping grasses and food processing. The species of starch grains retrieved from the study sample reveal that diverse crops were cultivated at the Changning site 4000 years ago.     

论近代中国后发棉纺织小企业的纵向一体化战略——以常州广益布厂为例

错过了＂黄金时代＂的部分后发棉纺织小企业通过纵向一体化战略成功发展成为中型企业集团。常州广益布厂,以棉织生产为战略突破口,抓住机器印染业方兴的趋势,先前向一体化印染生产,再后向一体化纺纱生产,最终发展成为大成纺织印染集团。这一战略给大成带来了节省交易成本、稳定交易关系、防御竞争对手的优效作用。这一成功案例为后发小企业的发展提供了借鉴。     

In Defense of "Geopolitical Remote Sensing": Reply to Moisio and Harle

The author of a recently published paper on Finland's identity politics and national identity (Antonsich, 2005) responds to comments presented in the preceding paper in this issue of Eurasian Geography and Economics (Moisio and Harle, 2006). The rejoinder focuses on the nature of place knowledge acquired "in place" versus "at distance" as well as on more specific differences in perspective (e.g., use of sources, terminology, critical geopolitcs).

Geographical Metanarratives in Russia and the European East: Contemporary Pan-Slavism

A specialist on Russian geopolitical metanarratives investigates the re-emergence of Pan-Slavism in the ideological landscape of contemporary Russia. Arguing that it is a heterogeneous assemblage of both mutually antagonistic and complementary narratives about the unity of Slavic peoples, the author posits that Pan-Slavism's durability lies not in its conceptual coherence but rather its emotional appeal to disparate Slavic peoples in the former Soviet Union as well as Eastern and Southeastern Europe. After briefly tracing the history of Pan-Slavism from its 17th-century roots through World War I into the Soviet period, he explores the metanarrative's capacity to take modern Russia's geopolitical thinking in new directions, including the potential to replace Russians' center-periphery worldview with a that of a cosmopolitan network of kindred nations affording Russia greater access to the European community.     

Prediction and its discontents: guidance for Australia from the debate over social science forecasting

The well-documented failure of many experts to predict many events of strategic importance—from 9/11 to the global financial crisis to the Arab Spring—has led to a fashionable belief amongst some academics and popular commentators that prediction is a ‘fool's errand’. Problems inherent in forecasting political events, such as cognitive biases, strategic interaction, complexity effects and various others, make this an attractive position. However, although a proper degree of humility is warranted about the ability to predict strategic events, this article argues that not making predictions at all is not an option. No genuinely workable policy advice could flow to Australian policy makers unless analysts are able, however roughly, to try to forecast the future. Moreover, with some hard, determined work, social scientists have recently produced work which promises to be able to foresee important events such as state failures and civil wars with reasonable accuracy. Experts should be encouraged to make, and should routinely be evaluated on, predictions about their area of expertise. Even failed predictions can be useful in pointing up gaps in knowledge and understanding which would otherwise have remained opaque.

试论1949～1959年中苏关系中的美国因素

1949～1959年的中苏关系,经历了从走向结盟到蜜月合作再到出现公开分歧的发展历程。美国作为影响中苏关系的一个外部因素,其制定的分裂中苏关系的楔子战略也经历了三个不同的发展阶段:从第一阶段以中国作为主要突破口,通过所谓灵活政策来阻止中苏结盟;到第二阶段仍以中国为主要突破口,通过强硬政策致力于分裂中苏的长远目标;再到第三阶段以苏联为主要突破口,通过软硬分施的策略来推动中苏同盟走向分裂。楔子战略的侧重点和实施手段不尽相同,效果也前后有别。
