Family education support to rural migrant children in China: evidence from Shenzhen

Rural migrant children have become a fast-growing population in China as a consequence of the large-scale population flow from rural to urban areas. Besides the dual-structure hukou system, which restrains rural migrants from upward mobility, family capital also plays an important role in providing family educational support to rural migrant children. Using the data from P District and N District of Shenzhen in 2013, this paper explores the present status of three dimensions of family capital and five aspects of family educational support to Chinese rural migrant children, as well as the correlation between family capital and family educational support from perspectives of migration status (hukou), life course (children’s age), and school type. Constrained by inadequate family capital in multiple dimensions manifested by less education, lower income, and limited social networks, etc., parents of rural migrant children provide less family educational support in nearly every aspect compared with parents of urban local children. Among rural migrant children, those in private migrant schools receive the least support from their parents.     

Within-development density and housing prices in Singapore

This paper measures how much more households pay for less density in their immediate surroundings. Using transaction and administrative data and exploiting the introduction of a regulation that restricted the number of housing units for certain land lots, we find that households discount density: a 10% increase in within-development density decreases the price per square meter by 5%. Further, the mean price per square meter of the average development increased by 1%–3% after the regulation was introduced, while the amount of built-up space remained constant. The increase in total revenue suggests developers may underestimate the externality caused by density.     

The Complexities of a New Faith: Xu Guangqi's Acceptance of Christianity

Xu Guangqi (1562–1633) was one of the most important early Chinese Catholics closely associated with Matteo Ricci (1552–1610), the legendary founder of the Jesuit China mission. In spite of his widespread fame since the seventeenth century, the precise nature of his religious experience has not so far been adequately investigated. To understand his complex relationship with Christianity and thereby gain insight into the fateful East–West intellectual interaction in the early modern period, this article closely probes various aspects of Xu's spiritual journey including his family history, his reception of baptism, and his association with Jesuit missionaries both before and after his conversion, and the particular character of his Catholic faith.     

Non-destructive provenance study of chert using infrared reflectance microspectroscopy

In this paper we explore the potential of non-destructive Infrared reflectance microspectroscopy (IRRMS) for the characterization of chert samples from 10 different geological outcrops in North America with emphasis on the Midcontinent. A principle objective of the project is to determine whether IRRMS analysis can provide a mineral-based signature for bedrock sources of chert artifacts. The technique utilizes a Bio-Rad Digilab FTS-40 Infrared spectroscope and microscope attachment that reflects an infrared beam off a chert specimen. Our findings indicate that spectral features from the molecules constituting minor and trace minerals in chert may provide sufficient characterization for chert sourcing.

大连地区出土汉代青铜器浅析

青铜器在夏代开始铸造,经历了育成期、鼎盛期、转变期、更新期,到汉代因为漆器、早期青瓷和釉陶的广泛使用进入了衰退期。此时青铜器的职能也发生了转变,由先秦的为礼制服务进入了重人阶段。追求人的价值,享受人生乐趣成为时代思潮,使用铜器是为了方便生活,享受生活,所以此时期的铜器,

受阻胺H-622改性B72及光稳定机理研究

为了提高B72文物保护材料的耐光性能,采用高分子量受阻胺H622对B72进行物理共混改性。监测了改性材料老化前后的颜色、失重等参数的变化,并探讨了受阻胺的稳定机理。实验结果表明,经受阻胺H622改性后,材料的耐光老化性大大提高,红外光谱、接触角、失重、硬度等指标的变化明显较改性前降低。同时观察到老化近500h时,改性材料的颜色基本不变。受阻胺H622对B72的稳定作用是由于受阻胺吸收光能后转变为可以再生的氮氧自由基,能捕获B72老化降解产生的自由基,从而阻止B72降解反应的不断进行。由此可见,采用受阻胺H622改性B72是可行的,提供了一种延长B72寿命的新方法。

寢戈考

《左傳》所載名物,多有不可識者。本文以出土實物考證《左傳》所載"寢戈"的特點與用途。戈是古代各兵種作戰中常見的進攻型武器,戈的形制根據兵種的不同和實戰的需要而有所不同。《左傳》所載寢戈,屬小型貼身自衛的武器,自然在形制上與徒戈和車戈等實戰用戈有明顯區别。
