引进外资对中国工业化和经济结构变化的影响

本文从中国经济增长两个阶段的不同特点入手,分析了90年代中期以后中国大量引进外资的深层次原因。采用制造业增加值占GDP的比重作为衡量中国工业化进展程度的指标对整个90年代中国工业化的进程进行了实证分析,结果发现,中国的工业化从90年代中期以来实际上长期处于低速徘徊的阶段。大量引进外资导致中国工业化过程中存在两个明显的"替代效应",一是"外资替代效应",二是"弱质替代强质"现象。两个"替代效应"对中国工业化和经济结构变化的影响是极为深刻的。     

中国大城市贫困研究的多种测度与多层模型分析

基于六大城市住户调查数据,采用多种贫困测度和多层模型分析的方法,探讨中国大城市居民贫困状况及其影响因素。研究发现,大城市低收入邻里的贫困状况存在较大差异,其中广州、西安的相对丢失(relative deprivation)严重且低收入群体层级结构复杂,昆明的贫困深度大,而武汉财富集聚相对明显。贫困多层模型表明低收入邻里贫困的主要影响因素仍存在于个体层面,个体在家庭制度、市场制度、国家福利供应中所表现的特征影响了贫困发生率;城市贫困同时存在邻里效应,主要体现在邻里经济状况和贫困文化的影响作用;而城市间的贫困差异亦不可忽视。     

简论曹操对乌桓的征讨及意义

乌桓和袁绍势力的联合是导致曹操征讨乌桓的主要原因之一。在如何对待乌桓的问题上,曹操势力内部意见最初并不统一,但曹操最终采纳了郭嘉的建议,决定出兵乌桓。曹操北征乌桓的胜利,不仅将北疆分立的各政权纳入自己的管辖之下,实现了对北部地区的统一,而且为整军南下,专力于对付割据江东的孙权,以及亡命南方的刘备等解除了后顾之忧,但更重要的是中断了乌桓实现民族统一的历史进程,为乌桓人最终融合于汉等其他民族提供了前提。     

金融危机对青海地方税收的影响及对策

由美国次贷危机引发的全球金融危机,给我国经济发展带来了一定影响,进而对地方税收也产生了较大影响。本文结合青海实际,首先分析了金融危机背景下青海地方税收呈现的主要特点;进而从不同角度深入分析了影响青海地方税收增减的主要因素;最后提出了金融危机背景下促进青海地方税收增长的路径选择等。     

过滤理论的起源、概念及研究进展

过滤是住房的生命周期与家庭的生命周期之间相互作用的产物,包括两大支流:以建立经济理论和模型为代表的关注住房的过滤研究、有关居民迁居的强调家庭的过滤研究。过滤理论的地理学视角可以追溯到霍伊特(Hoyt)的扇形模型,提供了关于居民迁居和城市社会空间结构之关系的解释。过滤理论意义主要有:为低收入群体提供合适住房、解释城市微观和宏观空间变化、分析和解释与住房市场有关的社会问题。过滤理论是中国城市转型研究的新视角。     

The radiocarbon reservoir effect: new evidence from the cemeteries of the middle and lower Dnieper basin,Ukraine

This paper presents preliminary results of new radiocarbon dating of human, faunal and fish skeletal remains from a number of the cemeteries from the Middle and Lower Dnieper Basin, Ukraine. The results appear to demonstrate the presence of a radiocarbon reservoir effect during the Neolithic–Eneolithic periods, the first time that this has been identified in this region. The data indicate that the radiocarbon reservoir effect is currently only evident during these periods, and not in the earlier Epipalaeolithic–Mesolithic periods, prompting the suggestion that the radiocarbon reservoir effect is associated with elevated fish consumption from the Neolithic period onwards.     

Radiocarbon dating of marine shell samples. The marine radiocarbon reservoir effect of coastal waters off Atlantic Iberia during Late Neolithic and Chalcolithic Periods

Radiocarbon dates on marine shells have not been used as extensively as charcoal or bone dates for the setting up of absolute chronologies because interpreting these dates is complicated by the marine radiocarbon reservoir effect. Nevertheless marine shellfish were used widely at least during the Holocene and their shells are abundant and usually well preserved in archaeological deposits located near shorelines. Consequently prior research concerning the oceanographic conditions and the marine radiocarbon reservoir effect of a particular coastal area is needed in order to set up reliable chronologies for that region. Values of regional marine radiocarbon reservoir effect – ΔR – of coastal waters off Atlantic Iberia, some of its variability along the Holocene and its correlation with the upwelling phenomenon were determined during previous research. More data related to the ΔR values for western Portuguese coastal waters during the Late Neolithic and the Chalcolithic, a time interval badly sampled in previous research, were recently obtained. These values can be compared with ΔR values already determined for the Gulf of Cadiz. Besides the importance of these values for a better knowledge of the palaeoceanography and palaeoclimatology of Atlantic Iberia, from now on archaeologists can set up reliable chronologies for Late Neolithic and Chalcolithic contexts using marine shell samples of that origin for radiocarbon dating.     

THE SYNTAX OF OBJECTS AND THE REPRESENTATION OF HISTORY: SPEAKING OF SLAVERY IN NEW YORK

The representation of history continues to evolve in the domain of museum exhibitions. This evolution is informed in part by the creation of new display methods—many of which depart from the traditional conventions used to achieve the "museum effect"—in part by an increased attention to the museum-visitor relationship. In this context the ethical force of bearing witness, at times a crucial aspect of the museum experience, has emerged as a particularly compelling issue. In seeking to represent and address atrocity, injustice, and the abrogation of human rights, museums have the potential to become "sites of conscience" and to encourage "historical consciousness." Through a series of three exhibitions devoted to slavery, the New-York Historical Society demonstrated how such sites can be constructed and how objects can be deployed to represent extreme or "limit cases." In this review/essay I investigate and interrogate these exhibitions, looking closely at the use of objects as a source of "indirect testimony" (Marc Bloch) and at the "dialogical situation" (Paul Ricoeur) that might arise in an encounter among objects, exhibit narratives, and visitors. Thinking in terms of point of view, I look at the variety of rhetorical platforms from which objects speak in these exhibitions; thinking in terms of syntax, I look at the effects of ordering and of the radical juxtaposition of objects; thinking in terms of irony, I look at the provocations of double-voiced narratives and at how objects are used to support those historical sentences.     

郭世宝博士与加拿大华人新移民研究述评

论文评述了加拿大卡尔加里大学教育学院教授郭世宝在加拿大华人新移民研究方面的学术成果。认为他在华人新移民、华人社团、移民的外国文凭认证、文化多元化与高等及成人教育研究方面成就突出,其中在华人新移民研究方面有两项理论创新：在华人新移民融合研究方面提出了＂三重玻璃效应＂理论;在华人新移民回流研究方面运用了＂双重离散＂理论。     

A note on physical properties of musket fire

While the use of ballistics data and principles to clarify historical experience of firearms is to be encouraged, their application is not always straightforward. This paper emphasizes the need for care. An example is given of too sanguine reliance on period studies, specifically of muzzle velocity, and of inadequate appreciation of the physics, in particular of the Magnus force.
