内蒙古自治区社区干预在新冠肺炎防控中的作用机制及影响因素探讨

社区作为基层自治组织以其独特的职能和地位对重大公共卫生事件防控产生影响。本文构建社区干预机制体系,并基于内蒙古社区防控新冠肺炎的实证分析,探讨社区干预在地区和城市、农牧区间的差异,结合问卷得分情况并运用主成分分析法分别探讨影响地区间、城市和农牧区社区干预的主要因素。研究发现：内蒙古中部地区社区干预表现突出,东部其次,西部最差,城市社区干预显著优于农牧区;组织架构和职能发挥对地区内的社区干预效果影响较大。城市社区干预以组织架构和职能发挥为主,内外联系为辅,农牧区社区干预强调组织架构和内外联系,职能发挥薄弱;社区干预依照“组织架构响应--自身职能发挥--内外联系建立”的机制推进。     

Raspadita: a new lithic tool from the Isthmus of Rivas,Nicaragua

A new lithic tool type was discovered at the Pacific Nicaraguan archaeological site of Santa Isabel (AD 800–1350) and named raspadita (small scraper). Thousands of these small tools (1–2 cm in length) were found. They have a rounded proximal edge and a pointed distal end. In this study, the raspaditas are proved to be a coherent tool class with minimal variation in size, shape, material type and usewear. They were manufactured from white chert bladelet cores using soft hammer percussion and pressure flaking unifacial retouch. Usewear points to a composite tool form and a scraping function for the raspaditas. Scanning electron microscopy determined a ventral leading, dorsal following, unidirectional scraping motion for the raspadita proximal end. The material that was scraped has still to be definitely determined but phytoliths visible in the SEM images suggest that the composite tool was used for plant processing.     

安定战略与南唐方镇体制的崩解

南唐方镇在许多方面都发生了重要变化,这些变化引发了方镇体制军事特质的丧失,因此南唐方镇的体制实际上已不再是原先的军政体制,而是一种新的民政体制。决定南唐方镇体制崩解的根本因素是安定战略。五代十国时期是一个特别值得重视的在政治体制方面发生变化的关键时期。

试论夏商城市水利设施及其功能

本文就考古所见夏商城址内的水利遗存进行了分析,对夏商城市水利设施的种类、功能、渊源等相关问题进行了初步探讨。     

试论考古类型学的逻辑与原则

类型学作为认识工具,只涉及科学发现与检验的原理和逻辑,并不涉及具体事实。考古类型学由分型和分式两部分构成,分型即分类,分式即排序。本文借《元君庙仰韶文化墓地》和《试论殷墟文化分期》两篇论著,以集合论的原理和知识说明分类的逻辑,得出穷尽性、排他性、同一性三条原则;以函数的思想说明排序的逻辑,得到同一性原则。     

关于中国早期国家的几个问题

目前学术界对有关中国早期国家的概念存在着分歧.我们认为中国早期国家是指夏商周三代已具备公共权力,但社会仍滞留在居民血缘组织基础之上的政治组织.所谓中国在龙山时代就已出现了早期国家的说法是不能成立的.至于中国早期国家的产生,则是走的部落联盟酋长因其职务的“独立化“转变为“社会主人“这样一条路径.     

评近年来关于知识分子研究的几本史著

学术界近年来关于知识分子问题的研究呈现三大特点：一,“体验中的理解”,利用研究主客体在血脉、情感上的亲密关系,勉力进入先辈生存的精神家园,以理解他们的所思所言所行;二,“建构中的阐释”,力求在某种独特、精致的理论建构中提出假设,表达观点完成叙述;三,“批判中的反思”,通过广义上的学术批判,对古往今来的士之论士、儒之论儒、知识分子之论知识分子的成果进行反思。此外知识分子研究的方法论问题,也值得引起关注。     

Simon McBurney’s Ambitious Pursuit of the Pure Maths Play

Abstract

When Simon McBurney set out to create a play about the fabled relationship between Cambridge mathematician G. H. Hardy and the self-taught Indian genius Srinivasa Ramanujan, he was immediately confronted by the question of how to engage the mathematics authentically. Undaunted by his own uneasiness with the subject, McBurney incorporated a host of experts into the rehearsal process, calling on mathematical educators, expositors, and Fields medalists to come work with the company. While on the surface maths and drama make an incongruous pair, the result was a vibrant collaboration. The final product — the award-winning play A Disappearing Number — shines an interesting light on the surprising similarity between the creative process in mathematics and the creative process in theatre, especially as manifested by the company at Complicite.     

Interpreting pachyderm single carcass sites in the African Lower and Early Middle Pleistocene record: A multidisciplinary approach to the site of Nadung’a 4 (Kenya)

Nadung’a 4 is one of the single carcass pachyderm sites recorded in East Africa during the Lower and Early Middle Pleistocene. The site has yielded an abundant lithic assemblage in close association with the partial carcass of an elephant. Conjoined pedological, geoarchaeological, spatial, technological, and taphonomical analyses have been carried out to address the relationship between hominids and elephant. The resulting data are consistent with a non-fortuitous association between both categories of remains. The lithic artefacts do not match a classical Acheulean tool-kit, as would be expected for the time period ascribed to the site, and the functional patterns inferred from their analysis make this site radically different from other purported butchery sites. The implications of these original features are discussed.
