中毒死者体内毒鼠强的GC/MS-SIM分析

一 1 9岁男子赌气吞服一白色粉末 ,1 0min后口鼻流血、抽搐 ,迅速送医院 ,经催吐、透析等方法治疗 5天后死亡。根据中毒症状和经验怀疑为毒鼠强中毒。用GC/NPD检验肝中毒鼠强有干扰。改用GC/MS -SIM法分析 ,心血、肝和胃组织中全部检出毒鼠强 ,浓度分别为 0 5 1 μg .mL- 1、0 4 5 μg .g- 1和 0 33μg .g- 1,和文献结果在同一水平。GC/MS -SIM对复杂检材中低含量毒鼠强测定具有更高的选择性 ,也具有较高的灵敏度 ,同时进一步证实毒鼠强排泄较慢 ,经过较长时间后在体内分布比较均匀     

国际金融市场研究方法的逻辑演变——有效市场假说面临的挑战

有效市场假说作为金融经济学的理论基石,无疑是我们研究国际金融市场的重要方法和依据。许多其他得到广泛 应用的金融投资理论皆以此为基础。历经30年的发展,有效市场理论在不断得到支持的同时,也面临了许多新的市场理论的挑 战。混沌理论和分形市场理论,特别是对于市场异象做出新解释的行为金融学,都从不同角度对传统有效市场理论进行了突破。这 不仅为研究国际金融市场提供了新的思路和方法,也对金融市场的决策者和生产者有着巨大的现实意义。     

Stamped out!: Carto-philatelic evidence of the PRC’s constructed notion of China’s territorial integrity

Carto-philatelic imagery illustrates that the “mental map” of China underlying territorial policies of the People's Republic of China is constructed, contingent, and impermanent. Although it has claimed Taiwan by asserting primordial sovereignty, declaring the island to have been part of China “since ancient times,” the ruling Chinese Communist Party (CCP) has not always viewed the island as part of China. Although it recognized the independence of Mongolia in 1950, before it came to power as the government of the state the CCP envisioned Mongolia as part of China. Postage stamps issued in territories governed by the CCP before 1949 juxtaposed to stamps issued by the Republic of China government affirm what documents suggest: that China's boundaries have not been immutable and have been highly contested by Chinese political elite. This should prompt readers to view with skepticism categorical claims about China's sovereignty and “territorial integrity.”

The Impact of Language Status as an Acculturative Stressor on Internalizing and Externalizing Behaviors among Latino/a Children: A Longitudinal Analysis from School Entry through Third Grade

This study examined the relationship between limited English proficiency status, and internalizing and externalizing behaviors among a sample of Latino/a children (N = 2,840) from the US Department of Education’s Early Childhood Longitudinal Study, Kindergarten (ECLS-K) data set. Results of cross sectional regression and hierarchical linear modeling (HLM) analyses suggest that there is a positive relationship between limited English proficiency and externalizing symptoms, particularly by third grade. Additionally, sex and place of birth also helped to explain externalizing behaviors at various time points in the models. Place of birth and family poverty were significantly associated with internalizing symptoms. Implications for future research and interventions related to internalizing and externalizing behavior among the Latino/a school aged population are discussed.

古代中国与朝鲜的“气”哲学传统比较

在中国,元气自然论在王充以后,受魏晋玄学思辩哲学的压抑一度发展低迷,到北宋张载时走向高峰而发展为元气本体论,后又受程朱"理"论的排挤,一度衰微。300年后,王廷相、王夫之的气论又形成发展高潮。在朝鲜,确立气一元论哲学的徐敬德之后,气哲学传统就表现为主理主气之争、唯理唯气之争,最终由崔汉绮总集成。中国的气论主要作为宇宙本根论,道器、形而上、形而下等范畴始终成为诠释的中心。朝鲜的气论则更多地是对心、性、情等伦理本体的探讨,故主要围绕理气、心性、善恶等概念进行了研究。     

Lessons of Russian in Afghanistan

The experience of Soviet involvement in Afghanistan (1979–1989) is considered through the prism of institutional transfers. Afghanistan has a long history of attempts to implement Muslim, Soviet and Anglo-Saxon institutional designs. Most of them have failed. This failure can be attributed to the lack of ‘elective affinity’ between traditional and new institutions imported from more developed countries. It is argued that a careful examination of the degree of elective affinity must precede any attempt of institutional transfers. An analysis of Ph.D. dissertations defended by Afghan students at Soviet and Russian universities complements logical arguments and references to historical facts.
