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.     

The impacts of parental migration on children’s subjective well-being in rural china: a double-edged sword

ABSTRACT

The emerging problem of left-behind children has attracted mounting academic and policy attention. Prior studies primarily cast light on left-behind children’s education, health, and behavior, while their subjective well-being is much less understood yet. Based on a nationally representative sample of rural children aged 10–15 in 2014, we examine the impacts of different types of parental migration on children’s subjective well-being and how these affects vary between boys and girls. The results show that parental migration is a double-edged sword: children from both-parent migrant families report compromised life satisfaction and relationship quality compared with those in integral families, and mother-only migration significantly lowers children’s subjective health. On the flip side, father-only migration enhances children’s aspiration for attaining college, an encouraging effect that is even stronger than that of parental education and family income. These effects are heterogeneous by children’s gender: boys seem to be more susceptible to the disruptive effects of both-parent migration; mother-only migration effectively promotes girls’ educational aspiration while father-only migration promotes boys’. This study portrays a comprehensive image of left-behind children. Relaxation of hukou restriction, equal access to education, and revitalization of rural economies are imperative to improve the well-being of left-behind children.

长沙风篷岭汉代漆器制作工艺中淀粉胶黏剂的分析

为研究汉代髹漆工艺中是否含有淀粉粘结剂,利用淀粉粒分析方法提取了长沙风篷岭汉墓出土的漆器残片中的残留物.实验结果显示:在偏光显微镜下观察到具有十字消光特性的淀粉颗粒,粒度大小在13至25μm,且有加热糊化的现象,加热温度在60至80℃,加热时间大约在30min以内.本实验证实在汉代漆器制作过程中使用了淀粉作为粘结剂,为研究汉代漆器的制作工艺提供了新的科学方法.     

丝绸之路外国旅游者旅游动机及旅游行为特征——基于跨文化比较的视角

本文以丝绸之路外国旅游者为例,选取西安、敦煌、乌鲁木齐和喀什4个城市为研究地点,采取问卷调查和访谈相结合的方式获取一手资料,从跨文化比较的视角,深入分析了5个文化类别国家的旅游者在旅游动机和旅游行为特征方面的差异。研究结果表明：旅游者主要推力因素是拓展视野,主要拉力因素是旅游景点,且5个文化类别国家的旅游者在推拉因素上存在一定差异;各文化类别旅游者在旅游计划、旅游方式、计划停留天数和旅游路线安排等行为特征方面有显著差异。研究结果表明文化因素对旅游者旅游动机和行为特征均有影响。     

《里耶秦简》(壹)所见作徒管理问题探讨

秦代编制作徒簿的机构有授予方的司空和仓,但二者分工不同;接收方包括库、田官、畜官、少内、属乡等。作徒簿分为临时付受与月度统计两种。秦代各级地方机构对刑徒管理的分工为:郡提出指导原则,县掌握本县刑徒的数据,县属机构负责具体管理。在当时人的观念中,徒隶是一个阶层的泛称,但在司法行政文书中则有特定的内涵,司寇不包括在内。

从地方志的考察中看明清人的奢靡观

本文以地方志为基本资料进行考察,认为传统意义上广义的奢靡观念可以从以下几个方面界定:1.某事项的花费超过该事项的基本需要;2.某些不正当不应有的消费项目与活动;3.某消费与个人(或部分人)的收入不相称;4.消费者攀比浮夸。奢靡观念的新旧激荡反映出明清社会的变迁及其局限性。     

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。     

历史时期射阳湖演变模式研究

射阳湖历史上曾是江苏境内著名的大湖。历史时期,湖区经历了浅水海湾—古泻湖—淡水湖泊—沼泽性湖泊—平原沼泽的演变模式。春秋以前,本区是里下河浅水海湾的一部分;春秋至唐代,本区由古泻湖逐步演变为淡水湖;南宋以来,1128年黄河夺淮以后,大量泥沙进入本区,湖区淤积迅速,成为沼泽性湖泊,加之人类开发活动的深刻影响,射阳湖逐渐演变为里下河平原的一部分。
