八指头陀诗歌中的梅意象

近代著名诗僧释敬安的诗歌中,咏梅诗占所有咏物诗之冠,有129首,其中直接以梅命题的诗有19首,梅意象出现的频次也最高,有146次,成为其诗歌的第一意象。其咏梅的角度多种多样,主要是通过与其他花木鸟物并举的意象组合的方式,运用多种修辞手法,托物言志,通过抒发对梅的喜爱,表达诗人对在艰苦环境中生存,并塑造魅力人格的追求。     

冷战后美国外交政策意识形态的道德神话及其悖论

意识形态作为象征符号、价值观同信仰相结合的完整体系是任何社会结构的重要组成部分,必然成为一国国家战略的重要内容。冷战后美国以“遏制”、“削弱”苏联为目的的反共产主义战略迅速转向“全球民主化”攻势,并表现于新干涉主义、新保守主义和新现实主义三种意识形态政策话语。美国外交政策意识形态内涵着巨大的裂痕与冲突,即存在普世价值与全球扩张主义;“欢迎一个强大、繁荣、成功和巩固国际规范、增进全球安全与和平的中国”与“结网--对中国有条件的套住政策”;理想主义与“美国式的资本主义已经从神坛上跌落下来”;“天赋人权”、“人人自由平等”的双重标准四个方面的悖论,表现出美国“人权神话”、自由女神像背后的反人权、反自由的伪善嘴脸。     

Population pressure and fertility in pre-transition Thailand

Before the demographic transition in Thailand, fertility was high, but not uniformly so. As in other pre-transition settings, Thai fertility responded to pressures and opportunities created by socioeconomic structure and land availability. Drawing upon provincial data from the 1947 and 1960 censuses of Thailand, we find a strong 'frontier effect' on Thai fertility in the 1950s. Fertility was higher in sparsely settled frontier provinces and lower in provinces with higher population density relative to cultivatable land. This finding is robust and holds up with controls for agricultural employment, land quality, and the sex ratio (an indicator of sex-selective migration). The effect of population pressure lowers the likelihood of marriage and of marital fertility. The findings from Thailand are consistent with the research of Easterlin on the nineteenth century United States and with other pre-transition societies. We suggest how demographic transition theory might be broadened to include fertility dynamics in pre-transition societies.

Stochastic comparisons of two-unit repairable systems

Abstract

We consider two models of two-unit repairable systems: cold standby system and warm standby system. We suppose that the lifetimes and repair times of the units are all independent exponentially distributed random variables. Using stochastic orders we compare the lifetimes of systems under different assumptions on the parameters of exponential distributions. We also consider a cold standby system where the lifetimes and repair times of its units are not necessarily exponentially distributed.     

兽用速效感冒注射液质量标准的研究

本研究按照农业部《新兽药及兽药新制剂管理办法》的有关要求，除制定出该注射液各药含量及其限度、性状、pH值检查、贮藏条件和有效期等项质量标准外，尚确立了腐植酸显色反应和沉淀反应的鉴别项目，筛选出分光光度法作为控制该注射液色泽的检查指标，并从复方注射液中定量测定出挥发油的含量。该质量标准经四川省兽药监察所检测验证，认为标准先进，方法可行。从而为该注射剂批量生产和质量控制奠定了重要基础。
