Study on the strontium isotope standard in pig teeth excavated from Zaoshugounao site,Shaanxi Province of China

In archaeology, strontium isotope analysis is developing into an efficient scientific technique for tracing the movement of prehistoric humans and animals. Determining the local bioavailable ⁸⁷Sr/⁸⁶Sr ratio range is the key to distinguishing whether the human or animal is indigenous to the local area. It has been shown that the ⁸⁷Sr/⁸⁶Sr ratio in the enamel of pigs can be an excellent sample to determine the range of local strontium isotope ratio at the site. However, pigs may not be all local at the site, and there is no special study on whether pigs’ different ages and tooth types impact the local strontium isotope characteristics. In this paper, the tooth enamel of 19 pigs from the Zaoshugounao site for strontium isotope ratio (⁸⁷Sr/⁸⁶Sr) by multicollector–inductively coupled plasma mass spectrometry. There were no significant differences in ⁸⁷Sr/⁸⁶Sr ratios of local pigs at different months and different molar types, which did not affect the determination of the local strontium isotope standard. Based on the local strontium isotope ratio range (0.711056–0.711476), we found that five pigs were non-local. The Jing and Wei river basins (in Guanzhong basin) and northern Shaanxi are likely sources of non-pigs.     

Political Commitment,Policy Ambiguity,and Corporate Environmental Practices

A lack of clear political commitment together with confusing rules and enforcement often characterize the institutional context of policy implementation and regulatory compliance in developing countries. By connecting such contextual features to existing models of policy implementation and regulatory compliance, we examine how regulatory factors are related to basic and proactive corporate environmental management practices in the Pearl River Delta region in China. Drawing on data derived from both a survey and in‐depth interviews, we show that a perception of clear political commitment to environmental protection across multiple government levels and units is positively associated with business efforts in basic environmental practices, regardless of the specific enforcement intensity. Nevertheless, a perception of clear political commitment is not related to proactive environmental practices. Conversely, a perception of policy ambiguity, in the form of confusing regulatory standards and enforcement, is negatively associated with corporate efforts in both basic and proactive environmental practices; yet, intensive inspections mitigate these negative associations with policy ambiguity.     

PLANTING TREES ON THE ROOF OF THE WORLD

媒人现象的社会作用及其演变

媒人是历史发展中的特殊民俗现象,也是一种特定的文化符号。媒人随一夫一妻制的聘娶婚的出现而出现,在防止男女乱性、保障婚姻安全、完善规范礼法等方面起着积极的历史作用。媒人不仅不会退出历史舞台,相反,在新的历史时期,媒人的社会作用将更加彰显。

晚清圣母圣心会中蒙古教区传教述论

本文认为,晚清时期,圣母圣心会在中蒙古教区获得了持续、稳定的发展。教会的成功既在于其传教方法得当,也在于教会拥有较多的社会资源。怎样评价教会的传教活动,并不是一个容易的话题。     

青州造像所见佛塔之样式、渊源与功能初探

青州佛塔具有相当的自身特色,即采用覆钵顶下高大的方形塔身,并且塔身四面均开龛置像。再考察与青州同时或稍早的云冈、龙门、响堂等处的佛塔,发现青州佛塔的来源当是北魏以来中原佛塔的典型样式,它的布局形式则明显受邺城地区佛像的影响。综合考虑北朝晚期的历史背景,青州造像上大量佛塔的出现,估计与法华经的信仰、末法的信仰有着一定的联系。而这时青州佛塔的功能则主要演变成一种装饰纹样。     

浙江省平湖庄桥坟遗址出土石犁的保护修复

浙江平湖庄桥坟遗址出土的石犁是史前考古的新发现,属于痕迹文物。出土时木构件痕迹饱水,为暗褐色、开裂严重、整体呈腐蚀状,非常脆弱。针对器物的保存状况,因地制宜地制定一系列保护方法:木构件痕迹的脱水保护、底托的加固制作、木构件粘贴复原等,使文物得以长期保存。
