The ripple effects of large-scale transport infrastructure investment

We analyze the general equilibrium effects of an asymmetric decrease in transport costs, combining a large-scale spatial dynamic general equilibrium model for 267 European NUTS-2 regions with a detailed transport model at the level of individual road segments. As a case study, we consider the impact of the road infrastructure investments in Central and Eastern Europe of the European Cohesion Policy. Our analysis suggests that the decrease in transportation costs benefits the targeted regions via substantial increases in gross domestic product (GDP) and welfare compared to the baseline, and a small increase in population. The geographic information embedded in the transport model leads to relatively large predicted benefits in peripheral countries such as Greece and Finland, which hardly receive funds, but whose trade links cross Central and Eastern Europe, generating profit from the investments there. The richer, Western European nontargeted regions also enjoy a higher GDP after the investment in the East, but these effects are smaller. Thus, the policy reduces interregional disparities. There are rippled patterns in the predicted policy spillovers. In nontargeted countries, regions trading more intensely with regions where the investment is taking place on average benefit more compared to other regions within the same country, but also compared to neighboring regions across an international border. We uncover that regions importing goods from Central and Eastern Europe enjoy the largest spillovers. These regions become more competitive and expand exports, to the detriment of other regions in the same country.     

The 1892 General Election and the Eclipse of the Liberal Unionists

This article seeks to establish that the 1892 general election marked a major change in the relative positions of the parties in the Unionist alliance. Not only did it reveal the limitations of the Liberal Unionist Party's strategy and appeal in an age of increasingly organised, mass politics, but it also acted as a brake on the ambitions of the new leader of the Liberal Unionists in the house of commons, Joseph Chamberlain. It argues that the Liberal Unionist Party suffered a more severe setback in 1892 than has been recognized hitherto and that Chamberlain's attempts to revive his party both before and after the general election were now prescribed by the reality of the political position in which the party now found itself. Rather than regarding the fluid political circumstances of the 1890s as the outcome of an emerging struggle between increasingly polarised ideologies, it seeks to reinforce the significance of local political circumstances and the efficacy of party management in the growing dominance of Lord Salisbury and Arthur Balfour and the Conservative central organisers.     

树立正确的战争荣辱观——论甲午战争中四位海军将领自杀

在甲午战争中,邓世昌、林泰曾、刘步蟾和丁汝昌等海军将领宁死不屈、战败自杀,其事迹可歌可泣,更发人深省。从他们成长经历和战斗事略,不难洞悉其自杀原因在于传统的忠君思想和荣辱观以及脆弱的国民性格。中国军人特别是各级将领应当知耻而后勇,树立正确的荣辱观,方能立于不败之地。     

从"资治"到"救国"--关于19世纪史学经世致用思想变化之研究

自19世纪40年代伊始,中国社会所发生的空前的沧桑巨变,直接推动了史学由古代史学向近代史学的转变。这种转变的重要标志之一,就是史学经世致用思想的变化,即史学经世致用思想从“资治”到“救国”,从着眼于王朝治乱兴衰到关注国家和民族前途命运之经世致用的宗旨和参照系的变化。同时,这种变化又对整个19世纪中国史学的发展及其走向产生了重大而深远的影响。     

城市发展指数指引下的我国收缩区域初步评判

城市收缩在全球范围内蔓延，致使以增长为假设前提的区域经济增长模型受到极大挑战。本文以县域单元为研究对象，利用2000年与2010年各县域单元的社会经济数据构建城市发展指数，在其指引下对我国城市收缩状况做初步分析。研究表明：①在城市化的快速进程中，我国县域单元出现收缩现象，特别是县、自治县、自治旗、旗出现较多数量的收缩。②发生收缩的县域单元共261个，大多数为人口较少的中小城镇；西部地区分布较多，且收缩面积较大。③收缩的县级行政区表现出一些共性特征：人口数量和密度下降、老龄化加深、医疗卫生条件较差、经济发展缓慢，财政赤字严重。这一结果有助于初步了解我国收缩区域整体格局，并呼吁研究者和政策制定者尽快针对这一问题展开研究，促进区域可持续发展。     

A New Methodology and Classification System for Describing Three‐Dimensional Particle Formats: Application to Clastic Lithic Products of Archaeological and Geological Origin

A new classification system is proposed to describe the volumetric formats of clastic lithic products of geological and archaeological origin. In order to build this operative classification, the rectangular block or cuboid is established as the standard geometric format to represent their three‐dimensional format (the X‐axis being length or long diameter, the Y‐axis being the width or intermediate diameter, and the Z‐axis being the thickness or short diameter) on a two‐dimensional diagram. To obtain this graph, each absolute coordinate (X, Y, Z) defining the prisms is projected on to an auxiliary plane with a new set of relative coordinates (x, y, z), expressed as the percentage of their sum. The projection generates a triangular diagram on which the indices of elongation and flatness are represented. A geometric transformation converting the triangular diagram into a quadrangular diagram has been produced in order to better represent the scatter points. Then, a double scale is necessary: (i) an absolute scale to quantify the indices, and (ii) a relative scale to calculate where the graphic locus is projected. This new graph also allows us to work with statistical parameters. Finally, two classic examples of applications selected from the literature are shown.     

南方地区古建筑木结构的整体性残损点指标研究

古建筑木结构的残损点指标是对古建筑木结构进行结构安全评估和加固修缮设计的重要指标,目前主要依据1992年制定的《古建筑木结构维护与加固技术规范》(GB 50165—92)中的规定,为了对该规范中的构架整体性残损点指标进行验证和补充,本研究通过对南方地区传统的穿斗木构体系和抬梁木构体系的典型榫卯节点和构架的试验研究,得出两种木构体系结构的整体性关键残损点指标,并与GB 50165—92规范进行比较分析。结果表明:规范规定的抬梁式木构架和穿斗式木构架的局部倾斜残损点比试验结果小,规范值偏于安全。规范中规定的抬梁式木构架梁柱榫卯连接残损点略小于试验结果,规范值偏于安全;而规范中规定的穿斗式木构架梁柱榫卯连接残损点对于燕尾榫穿斗木构而言是安全的,但对于透榫穿斗木构而言,则是不安全的。     

Evaluating Intensity in the Processing of Guanaco (Lama Guanicoe) at the Lower Basin of the Colorado River (Argentina): Fragmentation Levels and Fracture Patterns Analysis

This article explores the levels of fragmentation and fracture patterns in archaeofaunal assemblages from the lower basin of the Colorado River (Argentina) following Outram's methodology. Remains of ungulates (guanaco) have suffered, in these assemblages, a high degree of fragmentation probably caused during the processing of the carcasses. The presence of helical debris and shaft fragments indicates that fragmentation would respond to processing tasks for the consumption of marrow and possibly bone grease. The results of the application of this methodology that were obtained from the analysis of three late Holocene sites (La Primavera, Loma Ruiz 1 and El Tigre) are presented. These results provide new evidence not only for patterns of marrow and bone grease consumption but also for dealing with the subsistence model proposed for the study area. In this sense, the intensification processes already proposed during the final late Holocene (1000–250 bp ) are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

The Icelandic medieval monastic garden - did it exist?

In the multidisciplinary project presented here, 12 known monastic grounds in Iceland were surveyed by a group of medievalists from different fields in the summers of 2009, 2010 and 2011. The aim of the survey was to increase knowledge of the Icelandic monastic garden and of the plants that were known and used there; to look for possible medieval cultural relict plants; to observe continental influence on the island; and to vitalize discussion and research. Landscape and plants were surveyed at the 12 monastic sites, and full botanical investigations made. Many of the plants found have a medieval past as medicinal and utility plants, and some of their properties may have been common knowledge to medieval Icelanders. An investigation of written sources and archaeological and archaeobotanical findings from excavated sites added to the investigators’ knowledge. So were there monastic gardens in Iceland in the Middle Ages? The answer is a rather confident yes. With all the evidence combined, the investigators were able to trace the deliberate use of medicinal, food and utility plants in the monastic contexts. Whether they were cultivated, tended in situ, gathered growing wild or imported is another matter. Continental influence was more evident than has previously been observed.
