高梁──苏丹草杂交种干物质积累分配及光合性能的研究

研究表量，高粱—苏丹草杂交种的单株生物量高，其干物质积累量高于甜高粱杂交种和粒用高粱杂交种．各器官的干物质积累量以分蘖茎为最高．并且增长迅速．主茎和分蘖茎的干物质分配率在生育后期无负值．高粱—苏丹草杂交种获得较高生物量的原因是分蘖性强，致使产生较高的ＬＡＩ和ＣＧＲ．     

农业类型的演变与戎狄族群的兴起

农业类型的差异是古代中国区分华夏与戎狄、我族与他族的重要指标之一。春秋以前,在中国北方地区先后形成了旱作农业、非典型游牧农业和游牧农业三种具有地域性色彩的农业类型。新石器时代早期至晚商以前,北方地区农业类型的趋同发展与区域内部的频繁交流,是造成华夏与戎狄在族源关系上呈现复杂面貌的原因所在。晚商以来,非典型游牧农业类型在黄河上游-西辽河流域的发展演变呈现出区域性差异：甘青地区非典型游牧农业类型率先向游牧农业类型转型导致西戎族群最早成为威胁商周王朝西部边疆的劲敌;内蒙古中南部地区和西辽河流域非典型农业类型的分化,使北狄族群出现于山陕北部与燕山南麓地带。     

从人道主义精神看“安乐死”

本文作者从人道主义精神及儒家的生死价值观的角度,讨论“安乐死”所涉及的伦理问题,首先对“安乐死”的定义、词汇作一陈述,其次讨论“安乐死”牵涉的人道主义问题,最后引用儒家的经典,证明“安乐死”是符合儒家生死价值观的思想。     

《大唐西域记》与唐五代小说的创作

唐代,佛教已进入鼎盛发展阶段,高僧玄奘所著录的《大唐西域记》(以下简称《大唐》)广为流传,其中所记载的异域的奇异故事亦随之传播于民间。而当时小说创作中有大量题材取材于民间,两者的相互渗透是不可避免的。本文从《大唐》中梳理出部分题材,以大量实证材料证明《大唐》对当时"征奇话异"的小说创作产生深层影响。     

Politics: Butler's Corporeal Politics: Matters of Politicized Abjection

This essay examines the work of Judith Butler in relation to corporeality through an analysis of Bodies that Matter: On the Discursive Limits of Sex and Butler's notion of politicized abjection. Abjection is considered in relation to bodily materiality and proposed as the most promising path for a revamped corporeal politics. Through a reading of two novels, Katherine Dunn's Geek Love and Barbara Gowdy's Mister Sandman, the essay examines how the abject body can function as politically subversive. Throughout, the essay analyses Butler's placing of the material body in a political domain, and argues that she ultimately endorses materiality as potentially disruptive to the symbolic domain of viable bodies. This recasting of matter within her theory is shown as redefining the body as an active agent rather than a passive receptacle for regulatory norms. The essay examines this under-theorized aspect of her work, and illustrates that politicized abjection is as crucial to her philosophy as the notion of gender as performative.     

办好“第一要务”提高民族素质

文章认为,江总书记所提出的有关“第一要务”的科学论断,是在继承和发展马克思主义生产力理论基础上,考察当今世界的发展趋势并根据中国的实际得出的科学结论,它在“三个代表”的理论体系中占有重要地位,对我们做好民放工作、发展民族教育事业、提高民族素质具有重要指导意义。文章同时指出了在民族工作实际中办好“第一要务”需要加强的五个方面的工作。     

“物质是世界的本原”质疑

“本原”一词源于古希腊哲学关于万物始基的讨论,主要是指构成万物的基本要素、成分。现行哲学教科书提出“物质是世界的本原”,具有明显的逻辑矛盾。物质就其内涵而言是对万物的共同特性的抽象,就其外延来看则是万物的总和。所以,物质是世界的“本质”,而不是世界的“本原”。

Estimating the Risks of Smoking, Air Pollution, and Passive Smoke on Acute Respiratory Conditions

Five years of the annual Health Interview Survey, conducted by the National Center for Health Statistics, are used to estimate the effects of air pollution, smoking, and environmental tobacco smoke on respiratory restrictions in activity for adults, and bed disability for children. After adjusting for several socioeconomic factors, the multiple regression estimates indicate that an independent and statistically significant association exists between these three forms of air pollution and respiratory morbidity. The comparative risks of these exposures are computed and the plausibility of the relative risks is examined by comparing the equivalent doses with actual measurements of exposure taken in the homes of smokers. The results indicate that: (1) smokers will have a 55-75% excess in days with respiratory conditions severe enough to cause reductions in normal activity; (2) a 1 microgram increase in fine particulate matter air pollution is associated with a 3% excess in acute respiratory disease; and (3) a pack-a-day smoker will increase respiratory restricted days for a nonsmoking spouse by 20% and increase the number of bed disability days for young children living in the household by 20%. The results also indicate that the estimates of the effects of secondhand smoking on children are improved when the mother's work status is known and incorporated into the exposure estimate.
