School programs to prevent intrafamilial child sexual abuse

The incidence of child sexual abuse would argue for the schools assuming a larger role in the development of preventive and educational programs. Because of the public school system's consistent and longitudinal contact with children and families it is perhaps the most promising institution for the delivery of preventive efforts. This article presents specific suggestions for school-based programs directed toward the prevention of intrafamilial child sexual abuse. Further, it is argued that for maximum effectiveness, the support of local parent-teacher organizations be elicited; that educational programs be presented separately for parents and children; and that a variety of programs in concert with the development level of participants be presented on topics related to child sexual abuse. Topics regarded as important for prevention efforts are factual information on sexual abuse, appropriate and inappropriate touch, the respective role responsibilities and rights of parents and children, and a sex education approach that stresses the values of nonexploitation and discrimination in the choice of whether to engage in sexual behavior and the choice of partners.     

论河东盐池对华夏文明起源的重要作用

池盐是中国最古老的可供人们直接捞取食用的盐种。河东盐池位于华夏文明发源地的中心地带，有着几千年的悠久历史，河东盐池对华夏文明的形成有过独特而重要的也是无可替代的作用。特别是在华夏族的早期形成过程中，远专华夏族部落首领们曾为争夺盐源而战，有着地利优势的盐池也因此成为尧舜禹三代建都晋南的决定性因素，同时，盐池又是夏商周三代文明重要的经济基础。基于以上几个方面的原因。得出的结论是：盐池时华厦文明的形成有着最直接的或者说是决定性的作用。     

南京国民政府收回盐政主权斗争新探

以往研究范式是把恢复盐务稽核机关和稽核制度作为南京国民政府放弃反帝立场、继承北洋政府衣钵的标志。事实上,南京国民政府曾同列强进行过坚决的斗争,并成功收回盐政主权。南京国民政府恢复盐务稽核机关和稽核制度,主要为提高盐政效率,而改造后的盐务稽核机关已彻底为我所用,不再是列强控制中国盐政的工具。     

Bunte盐法制备巯基乙酸实验合成新方法

采用氯乙酸和碳酸钠反应生成氯乙酸钠,控制氯乙酸钠溶液PH值为8～9,在70～75 ℃下与等摩尔硫代硫酸钠反应生成Bunte盐,加入反应物重量10%的硫酸,控制温度为80～90 ℃,时间为80min进行酸化反应;再加入反应物重量2%的Zn粉在40～50 ℃下还原80min,得到粗产品;萃取、精馏后巯基乙酸纯度可达98.6%,收率可达到89.7%.     

内陆盐湖石盐流体包裹体均—温度指示意义的现代过程研究

Halite precipitation with water and air temperature was observed in detail, and homogenization temperature of fluid inclusions in halite formed in ancient and modem Chaka Salt Lake was studied. Halite precipitates mainly in August every year and largely precipitates between 13 and 15pm at one day when water temperatures reach 20℃ but can seldom reach 30℃. Homogenization temperatures of fluid inclusions in halite formed in Chaka Salt Lake range from 14℃ to 38℃ with an average of 23.7℃. The number of inclusions appears an obvious peak value at homogenization temperatures between 18 - 25℃, which probably represent the water temperature in which halite mainly precipitates when water temperatures reach 20℃. Therefore, homogenization temperatures of fluid inclusions in halite formed in Chaka Salt Lake can wall reflect the water temperature.
