本文通过分析罗马政府在不列颠的运作以揭示元首制时期罗马行省体系的运作机制。对总督及代理官任命之考察表明,罗马官员具有非职业性,他们生活在相对固定的晋升体系中,一生需要出任诸多不同职位,并没有为出任某个职位接受专门训练,所以无法发展出专业行政知识。此外,元首制时期官僚机构尚未增生,行省中罗马官员的数量屈指可数。这些都为地方自治开辟了空间。在某些罗马势力不易渗透的地方,地方自治政府在征服初期以藩属国的形式出现。随着时机成熟,藩属国作为一种权宜之计逐渐被具有高度自治权的城市所代替。城市里的地方官员在刑事案件之审理和直接税之征收方面发挥了重要作用。尽可能把行政负担转嫁到地方政府身上是罗马帝国正常运转的奥秘所在。  相似文献

Until now, the oldest known human hair was from a 9000-year-old South American mummy. Here we report fossil hairs of probable human origin that exceed that age by about 200,000 years. The hairs have been discovered in a brown hyaena (Parahyaena brunnea) coprolite from Gladysvale cave in South Africa. The coprolite is part of a hyaena latrine preserved in calcified cave sediment dated between 195,000 and 257,000 years ago. This find supports the hypothesis that hyaenas accumulated some of the early hominin remains found in cave sites, and provides a new source of information on Pleistocene mammals in the Sterkfontein Valley.  相似文献

馆藏壁画是博物馆藏品中一类特殊的文物。在馆藏大召寺壁画、陕西唐墓壁画等现状调查研究的基础上,本文分析馆藏壁画区别于原址壁画的特殊性,并提出针对馆藏壁画特点进行历史信息与现状调查的内容框架。强调壁画揭取历史、修复史、搬运史和保存环境等历史信息的调查对于认知壁画的重要性:壁画的现状调查包括本体调查和病害调查两部分,能够帮助保护工作者以科学的视角综合评价壁画保存现状。本文分别论述调查各个方面的意义、具体内容和方法。调查结果无疑对于制定保护修复方案具有重要意义,为合理实施保护修复提供科学依据,并为后续研究和档案记录提供基础信息。  相似文献

中国经济史的研究领域重点,多集中在中原、江南、口岸等城市,不关注西部民族地区城镇的历史状况,因此很难形成对中国城市发展起源、类型、特征总体的科学总结。笔者在日常文化遗产调研的业务工作中,发现贵州城镇中保留下来可供我们作为文化遗产观察、分析和研究的古代城市建筑物、街区、城垣等遗产已所剩不多,而究其原因是因为人们对城市发展的历史,对城镇历史遗物的文化价值、社会意义所知甚少。本文拟就明至清前期黔中地区的城镇发展史做一点粗浅论述,以引起专家学者对这一问题的关注。  相似文献

Research on the neurobiology and pharmacotherapy of attention-deficit/hyperactivity disorder (ADHD) has grown exponentially since 1980. A reasonable question is whether this research has improved our understanding and treatment of ADHD. This article describes relevant developments that took place roughly between 1900 and 1970. During this time, the efficacy of stimulant therapy for the disorder was established and the symptoms of ADHD were linked to many possible nervous system disorders including in the brain-stem, reticular formation, diencephalon, basal ganglia, frontal lobes, and cortex. In 1970, the catecholamine hypothesis of ADHD was proposed. It is concluded that early theories about the neurobiologic basis of ADHD anticipated core ideas of modern theory.  相似文献

Fezzeh Khanom (c. 1835–82), an African woman, was a slave of Sayyed ‘Ali-Mohammad of Shiraz, the Bab. Information about her life can be recovered from various pious Baha'i histories. She was honored, and even venerated by Babis, though she remained subordinate and invisible. The paper makes the encouraging discovery that a history of African slavery in Iran is possible, even at the level of individual biographies. Scholars estimate that between one and two million slaves were exported from Africa to the Indian Ocean trade in the nineteenth century, most to Iranian ports. Some two-thirds of African slaves brought to Iran were women intended as household servants and concubines. An examination of Fezzeh Khanom's life can begin to fill the gaps in our knowledge of enslaved women in Iran. The paper discusses African influences on Iranian culture, especially in wealthy households and in the royal court. The limited value of Western legal distinctions between slavery and freedom when applied to the Muslim world is noted.  相似文献

This study explores how a scientist's location in science‐based policy networks can affect her policy‐oriented behaviors. In particular, we hypothesize that those scientists who fill structural holes in their networks will be more likely than others to engage in policy‐oriented behaviors. The network data are defined by scientists' coauthorship on policy documents regarding climate change in the Great Lakes. We employ a two‐mode network analysis to identify clusters of scientists who coauthored similar documents, and relative to those clusters, we identify those who fill structural holes by bridging between clusters. We find that those scientists who bridged between clusters were more likely to engage in policy‐oriented behaviors of policy advocacy and advising than were others in the network. This is an example of a link between network location and policy‐oriented behavior indicative of the broader phenomenon of how individuals exert agency, given structural constraints.  相似文献

盟旗制度是清代施行于外藩蒙古的核心管理制度。然而该制度完善于雍正至乾隆时期,因文献资料匮乏,该制度如何形成、如何演变,于清朝初期如何运作均付之阙如。而清廷主管此事务的机构理藩院,却在其顺治年间上报题本中涉及该事务。通过顺治年间满文理藩院题本这一遗留性史料,探讨清初蒙古会盟制度雏形遂成为可能。本文即依据此全新资料,对盟旗制度形成前,蒙古的会盟情况进行探讨,通过对题本的文本分析,在前人研究的基础上进一步补充、完善清初会盟制度的运行过程,以求使此问题更加清晰明了。  相似文献

Charcoal-tempered pottery is uncommon in North America, but was produced with notable frequency in Northeast Florida from ca. AD 300–600. Thirty-six thin sections of pottery were analyzed by petrographic analysis and compared to 10 clay samples in order to characterize the paste of charcoal-tempered wares in terms of charcoal and mineralogical composition and abundance, assess the number of clay sources used to make the pottery, identify the species of wood represented in charcoal inclusions, and infer techniques of ceramic production. This analysis identified four temper categories, three texture groups, and three distinct clay resources used to make charcoal-tempered pottery, all of which were likely local to Northeast Florida. Identified wood taxa include pine (Pinus sp.), cedar (cf. Juniperus sp.), cypress (cf. Taxodium sp.), and sassafras (Sassafras albidum), with pine suspected to be the most common. These genera of charred wood, which exhibit minimal shrinkage in the samples, along with the prevalence of bone and grog inclusions, indicate that hearth contents were processed as temper, sometimes in combination with quartz sand. Potential reasons for the use of hearth contents as temper are considered.  相似文献
