中美科幻小说的创作及研究进路考察——基于1990年代以来的科幻文学视域

科幻小说诞生于19世纪的欧洲,是科技与文学的一种融合.这种文学形式,以其特有的叙事方式,承载着人类探求未来世界、认知未来社会的精神寄望与诉求.作为世界的共有资源,中美两国的科幻小说在其创作及研究的进路中有着较大的距离差别.美国的科幻小说虽较晚于启蒙国英国,但作为科学技术大国、强国,其创作和研究的超越提速是较大的,出现了诸如罗伯特·海因莱因及《星船伞兵》、艾萨克·阿西莫夫及"基地"系列、"机器人"系列等等这样的科幻小说巨头及巨作,研究的深入跟进亦趋于世界前列;相对而言,中国科幻文坛虽曾有过20世纪50年代的辉煌,诞生了郑文光等名家,但中国现代科幻小说的创作及研究是滞后的.20世纪90年代以降,刘慈欣的《三体》三部曲、王晋康的《逃出母宇宙》等科幻大作的出现,使中国科幻小说的创作及研究吸引了世界的目光,其影响在改变着这一滞后的局面.世界科幻王国终于有了中国的声音.     

清代中缅划界的法律之误

中英1894年签订《续议滇缅界、商务条款》,条约前5条是关于定界的规定,划定了除中缅北段未定界以外的边界。由于对有效占有的理解、条约文本、以及地图的失误,中国反而丧失了实际管辖的小江流域,也遗留下南段未定界。中缅近代遗留的南、北两段边界争端,除近代欧洲列强侵略原因外,也源于中国对领土划界、国际法领土取得和变更理论的理解不够深入和准确。因此,及时理解国际法有关领土理论的产生与变更、在积极运用国际法解决边界争端之时更谨慎地注意技术上的细节,才是真正解决国家边界争端的恰当方式。     

高含水期油藏层间压力结构差异量化方法研究

由于长期注水开发和层间非均质性影响，高含水期油藏各小层层间压力结构差异严重，掌握差异状况是合理调整的重要依据。针对现场分层测压资料少，单层压力资料获取困难的情况，应用渗流力学原理建立了高含水期地层层间压力结构差异量化数学模型，模型的关键参数可以通过生产数据计算获得。枣园油田的实例验证表明，高含水油藏层间压力存在明显差异，该方法能够确定各小层的压力差异状况。量化计算结果和实测资料相接近，有利于认清开发矛盾，为合理调整提供技术依据。     

互联网深化、信息不确定性与企业出口平稳性

互联网作为信息搜寻和传播的重要渠道,有利于缓解国际市场不确定性对企业出口决策的影响,从而有助于稳定企业出口预期,保障出口企业的持续生存。本文首先基于Fernandes 和 Tang(2014)的研究框架将互联网深化程度和出口集聚同时纳入到异质性贸易企业模型,在剥离出口集聚对企业出口行为影响的基础上,从理论视角揭示了互联网深化程度提高影响企业出口行为特别是出口持续生存的内在机理与方向。研究发现,不同于出口集聚会同时影响企业的需求冲击和成本冲击,互联网深化带来的信息溢出效应会通过贝叶斯法则(Bayesian Rule)使得企业修正其对国际市场不确定性的预期,提高其对目的国市场成本冲击的估计精度,从而在互联网深化程度较高的城市,企业进入出口市场的临界生产率较低,有利于其出口参与度和出口稳定性的提高。然而互联网深化程度提高不影响企业在目的国市场产品出口的集约边际。本文使用2000-2013 年中国工业企业数据库、中国海关数据库和中国城市统计年鉴数据库的匹配数据从企业-目的国-产品层面实证检验了本文的理论命题。研究表明,我国政府应充分发挥互联网发展降低信息不确定性的微观机制,以推动外贸的平稳增长。     

Modifications of sequential designs in bioequivalence trials

Bioequivalence (BE) studies are designed to show that two formulations of one drug are equivalent and they play an important role in drug development. When in a design stage, it is possible that there is a high degree of uncertainty on variability of the formulations and the actual performance of the test versus reference formulation. Therefore, an interim look may be desirable to stop the study if there is no chance of claiming BE at the end (futility), or claim BE if evidence is sufficient (efficacy), or adjust the sample size. Sequential design approaches specially for BE studies have been proposed previously in publications. We applied modification to the existing methods focusing on simplified multiplicity adjustment and futility stopping. We name our method modified sequential design for BE studies (MSDBE). Simulation results demonstrate comparable performance between MSDBE and the original published methods while MSDBE offers more transparency and better applicability.

Media Disaster Reporting Effects on Public Risk Perception and Response to Escalating Tornado Warnings: A Natural Experiment

Previous research has evaluated public risk perception and response to a natural hazards in various settings; however, most of these studies were conducted either with a single scenario or after a natural disaster struck. To better understand the dynamic relationships among affect, risk perception, and behavioral intentions related to natural disasters, the current study implements a simulation scenario with escalating weather intensity, and includes a natural experiment allowing comparison of public response before and after a severe tornado event with extensive coverage by the national media. The current study also manipulated the display of warning information, and investigated whether the warning system display format influences public response. Results indicate that (1) affect, risk perception, and behavioral intention escalated as weather conditions deteriorated, (2) responses at previous stages predicted responses at subsequent stages of storm progression, and (3) negative affect predicted risk perception. Moreover, risk perception and behavioral intention were heightened after exposure to the media coverage of an actual tornado disaster. However, the display format manipulation did not influence behavioral responses. The current study provides insight regarding public perception of predisaster warnings and the influence of exposure to media coverage of an actual disaster event.     

Premium of Endowment Insurance for Civil Servants will be Paid by Employers and Individuals

There is finally precise information about the reform in endowment insurance to abolish the"double-track system".On December 23,2014,Mr.Ma Kai,Vice Premier of the State Council,delivered a work report on behalf of the State Council at the 12th Session of the Standing Committee of the Twelfth National People’s Congress about the progress made in comprehensively advancing the establishment of urban     

美国、中国与朝鲜停战谈判中的战俘遣返问题

在1951年6月至1953年7月的朝鲜停战谈判中，战俘遣返问题是谈判双方争论最为激烈、耗时最长的议题。美国出于冷战需要，拒不同意遣返所有被俘朝中人员；而朝中方面则依据关于战俘遣返问题的日内瓦公约，要求遣返所有战俘。由于在此问题上僵持不下，致使谈判几次陷于停顿。最终，谈判双方各自做出一定让步，使得战俘遣返问题得以解决，为朝鲜停战协定的签订消除了最后也是最大的一个障碍。     

NETWORKING CAPITALISM: Network Construction and Control Effects In Direct Selling

Drawing on a qualitative study of direct selling in Taiwan, this article examines the process of network construction and its control effects over distributors. I found that weak ties, rather than strong ties, constitute major networks for distributors to expand their business. In order to consolidate trust within weak ties, distributors develop two major strategies: personalizing sales and familiarizing sponsorship. They are engaged in a multilevel performance of emotional labor in facing the audience of customers and fellow distributors. Social networks not only function as a facilitator of economic exchange but also become a meáns of labor control that permeates both public and private lives of distributors.
