Detection of parasite eggs from a moat encircling the royal palace of Silla, the ancient Korean Kingdom

We conducted a paleo-parasitological study on soil samples from the ancient moat ruins of Weolseong palace, of the Silla Dynasty (BC 57–AD 935) of Korea. Based on the cultural remains found in the mud-soil layer, the layer was precipitated onto the floor of a moat between the 5th and 8th centuries AD. We found Trichuris trichiura eggs only in that mud-soil layer, whereas no parasite eggs were identified in the other archaeological strata of the ruins. As T. trichiura eggs are shed only in human feces, we speculated that palace toilet contents were continually drained into the moat; therefore, at a certain point in time after construction, the moat finally became a ditch around the palace. Structures in the stone embankments of the moat, possibly designed to make the water flow continuously in one direction, might reflect the Silla people's efforts to alleviate the ever-increasing problems inherent in a moat.     

中共建党与近代上海社会

1921年7月,中共一大在上海召开。作为工业化、现代化和国际化都市的上海,为中共成立提供了最适宜的地理环境。以上海工人为主体的中国工人阶级的壮大和阶级觉悟的提高,为共产党的创建奠定阶级基础。上海发达的媒介网络为马克思主义的早期传播提供便利条件。伴随新文化运动的勃兴,上海成为先进知识分子的集聚与活动中心。以陈独秀为核心的《新青年》编辑部和马克思主义研究会则为中共上海发起组提供基本成员,上海发起组实际担当了组建中共的临时中央。中共在上海的成立是上海近代化的结果。共产党的成立及其初期的活动,构成上海近代史的华章。     

Testing the standardized growth curve (SGC) to OSL dating coastal sediments from the south Bohai Sea, China

It has been suggested that the standardized growth curve (SGC) method can be used to accurately determinate equivalent dose (D_e) and reduce measurement time. However, different opinions regarding the applicability of the SGC method exist. In this paper, we evaluated quartz OSL SGCs of marine and coastal sediments of different grain sizes and different cores in the south Bohai Sea in China, and tested their applicability to the determination of D_e values. Our results suggested as follows: (1) The SGC method is applicable to both multiple- and single-aliquot regenerative-dose (MAR and SAR) protocols of OSL dating and efficiently provides reliable estimates of D_e. (2) Finesand quartz of different palaeodoses showed highly similar dose-response curves and an SGC was developed, but old samples using the SGC method have large uncertainties. (3) For coarse-silt quartz, two different types of dose-response curves were recorded: low-dose (≤60Gy) and high-dose (≥100Gy). The growth curves of low-dose quartz were similar to each other, facilitating the use of SGC in D_e estimations, but errors tended to be larger than those obtained in the SAR method. For high-dose (100–300Gy) quartz, the SGC was also found to be reliable, but there was large uncertainty in D_e (>300Gy) estimation. We suggest that SGC could be employed for the dating of marine and coastal sediments dating using either MAR or SAR OSL protocol and either fine-silt, coarse-silt or fine-sand quartz.     

土默特平原聚落分布形态演变及其驱动因素分析(1934—2019)

选取土默特平原1934、1982和2019年的聚落人口数据,运用GIS空间分析法,定性与定量结合分析研究区聚落分布形态演变及其驱动因素,结果表明,1934—2019年土默特平原以小聚落为主,大规模聚落数量和比例逐年增加,人口等级结构由“扁平”向“长高”金字塔形转变。聚落空间分布整体呈现集聚分布特征,大规模聚落集聚性不显著,其他规模的聚落分布模式由随机向集聚转变,研究区人口极化现象显著;聚落空间分布非均衡发展趋势明显,呈现由极核式向点轴式演变的迹象;聚落网络联系的空间近邻效应显著,人口规模较大的中心城区成为强联系节点。地形、河流、交通是研究区聚落分布形态演变的主要驱动因素,聚落低海拔、邻河流、邻干道、邻城镇的指向性强。该研究便于厘清土默特平原近百年聚落分布形态的演变脉络,为当地聚落的空间布局优化与调控提供一定参考价值。     

Universities in inclusive regional innovation systems: Academic engagement and uneven knowledge use in Brazil

The purpose of this paper is to spatially and regionally examine academic engagement within Brazil, identifying patterns. Moreover, our investigation can contribute to a better understanding of how knowledge can be turned into a tool to fight regional inequality. We depart from two hypotheses: first, universities situated in peripheral regions interact more with companies from relatively more dynamic regions, and second, in the absence of industrial knowledge demand, universities tend to collaborate more closely with a diverse range of stakeholders in the region. To evaluate these hypotheses and find empirical evidence, we consider 4497 research groups and 4603 nonacademic organizations as “nodes” connected by 8830 collaborations throughout all Brazilian regions. Social network tools are used to illustrate the spatial and regional dimensions of academic engagement more accurately. The results show that academic engagement is not regionally homogeneous, demonstrating essential differences regarding local nonacademic partnerships. Innovation policies, which encourage only university–firm interactions, perpetuate regional inequality.     

张居正当国时期的中央财政制度改革——以太仓库为核心

本文以太仓库为切入点,指出张居正时代的中央财政制度改革是在屯田、盐法开中、民运等原有财政体系日渐无法满足北边军镇基本常规需求的情况下,在嘉靖、隆庆以来持续改革的基础上,为改变太仓库长期入不敷出的局面而进行的努力。这次改革在财政方面展现出强烈的中央集权化倾向,但其间太仓库收支渐增的趋势仍在,收不抵支的隐患仍存,北边军镇屯田等原有财政供应体系日渐失效的基本问题未能解决。张居正死后,太仓库财政状况迅速恶化。因此,张居正时期的改革仅仅是推延了明王朝财政崩溃的时间而已。     

Lights and Shadows: The Inquisitorial Process Against the Jesuit Congregation of Nuestra Señora de la Luz on the Mariana Islands (1758–1776)

This article focuses on the controversy over the charges of sexual impropriety made against Father Franz Reittemberger within the context of worship of Nuestra Señora de la Luz (Our Lady of Light) in the mid‐eighteenth century Mariana Islands. As is well known, this cult began to spread around the Americas and the Philippines (via New Spain) starting in 1740, and it became a cohesive force in a multiethnic society perched on the outskirts of Spain's overseas empire. The Society of Jesus arrived in the Marianas' archipelago in 1668 to found a mission with the economic support of Queen Mariana de Austria, Philip IV's widow and regent of Spain. In 1758 Father Reittemberger founded the Marian devotion to Our Lady of Light. After the expulsion of the Jesuit order from the Spanish islands of the Pacific (1769), the Augustinian commissaries of the Holy Office accused the congregation's founder of the crime of sollicitatio ad turpia. In examining this Inquisition trial Jesuit and Augustinian rivalries come to the fore, revealing the larger anti‐Jesuit sentiments that drove public censure of the colonial church in the Spanish overseas possessions.
