魏晋南北朝时期淮河流域的商业和城市

在魏晋南北朝时期,战争频繁,淮河流域商业遭到了严重破坏。但在各个战争间歇阶段,尤其自进入南北朝时期以后,南北政权统治区内的商业又有不同程度的恢复。南北双方间还存在着边境互市和以流域为中介地的聘访换货的贸易关系。商品交换媒介是谷帛、钱币并用。从总体上看,军事、政治成分重于经济是这一时期淮河流域城市的突出特点,但自进入南北朝时期以后,淮河流域城市的经济成分明显增长。

Stature and frailty during the Black Death: the effect of stature on risks of epidemic mortality in London,A.D. 1348–1350

Recent research has shown that preexisting health condition affected an individual's risk of dying during the 14th-century Black Death. However, a previous study of the effect of adult stature on risk of mortality during the epidemic failed to find a relationship between the two; this result is perhaps surprising given the well-documented inverse association between stature and mortality in human populations. We suggest that the previous study used an analytical approach that was more complex than was necessary for an assessment of the effect of adult stature on risk of mortality. This study presents a reanalysis of data on adult stature and age-at-death during the Black Death in London, 1348–1350 AD. The results indicate that short stature increased risks of mortality during the medieval epidemic, consistent with previous work that revealed a negative effect of poor health on risk of mortality during the Black Death. However, the results from a normal, non-epidemic mortality comparison sample do not show an association between stature and risks of mortality among adults under conditions of normal mortality. Fisher's exact tests, used to determine whether individuals who were growing during the Great Famine of 1315–1322 were more likely to be of short stature than those who did not endure the famine, revealed no differences between the two groups, suggesting that the famine was not a source of variation in stature among those who died during the Black Death.     

A Re-assessment of Entitlement Theory in the Light of the Recent Famines in Africa

This paper is an attempt to re-assess the nature of famines, as conceptualized in Professor Sen's entitlement theory, in the light of empirical evidence concerning the recent African famines. The paper identifies two critical phenomena that entitlement theory fails to explain. First, during famines, many people choose not to consume food rather than sell vital assets. Secondly, most famine mortality is not directly related to undernutrition, but is caused by outbreaks of disease. Sen's more recent work on poverty provides a framework for understanding these phenomena. The price of this is that entitlements themselves form only part of a larger account of famine. Some aspects of a revised account include coping strategies of famine-affected people, social disruption, and violence. In this account, less severe famine is not theoretically distinct from acute poverty, and severe famine is distinct largely because of the severity of social collapse, which in Africa usually follows violence.     

The Amsterdam Tapestry Producer Alexander Baert (1660–1719) and his Workshop: New Findings

Drawing on archival material relating to the Amsterdam tapestry producer Alexander Baert, much of it previously unpublished, this research note marks a departure from the prevailing, undersocialised, approach to tapestry production and trade in the Northern Netherlands. Data explored here for the first time show that, before emigrating from Oudenaarde, Baert was an active member of a rich network of tapestry entrepreneurs, but that ‘push factors’ such as legal and commercial problems along with ‘pull factors’ such as certain benefits and freedoms prompted his decision to move to the Republic. While earlier studies describe his activities there as an isolated process, it becomes clear that the entrepreneur and his descendants preserved enduring business ties in the Southern Netherlands. These networks furnished Baert with the infrastructure that enabled him to import tapestries from Antwerp, Brussels and Oudenaarde and to purchase Flemish cartoons cheaply.     

A hoard of Nilotic nacreous shells from Egypt to Jericho (Early Bronze II, 3000–2800 BCE): Their finding,content and historical archaeological implications

ABSTRACT

The Tell es-Sultan, ancient Jericho, is amongst the earliest “cities” that rose in the Southern Levant between the end of 4th and the beginning of the 3rd millennium BCE. The site is being excavated, studied and rehabilitated for tourism by Sapienza University of Rome and the Palestinian Ministry of Tourism and Antiquities since 1997. In 2017, during the 13th season of excavation, an unexpected discovery occurred: five Chambardia rubens shells have been found piled up in a dwelling unit dating back to the Early Bronze Age IB-II. The discovery is a tangible evidence of trade and cultural interconnections between the Southern Levant and Egypt, as these shells belong to a species that is only been found to live in the Nile. Moreover, chemical analysis, and thorough Scanning Electron Microscopy examination revealed that the shells contained Manganese Dioxide, an inorganic compound used as make-up ingredient in ancient Egypt, and available in the ores of the Sinai. These findings strongly support the existence of a link between the urban rise in EB IB-II through international trade of luxury goods, and are suggestive of the emergence at Jericho of a ruling elite that was influenced by Egypt.     

Naturwissenschaft und Religion in den Niederlanden um 1600

Dutch science flourished in the late sixteenth and in the seventeenth century thanks to the immigration of cartographers, botanists, mathematicians, astronomers and the like from the Southern Netherlands after the Spanish army had captured the city of Antwerp in 1585, and thanks to the religious and the socio-economic situation of the country. A strong impulse for practical scientific activities started from the Reformation, mainly thanks to its anti-traditional attitude, which had an anti-rationalistic tendency. Therefore, in the Northern Netherlands there was no ‘warfare’ between science and religion and the biblical arguments leading to Galileo's condemnation were not used. Although the growth of the exact sciences and of technology in the late sixteenth and the seventeenth centuries in Protestant cirles may be partly attributed to the expansion of trade, industry, navigation and so on, this does not explain why there was also at the same time a great interest in subjects as botany and zoology, which had no immediate economic utility. There were discussions about Copernicanism and Cartesianism. So a number of astronomers and theologians rejected the earth's movement on scientific and religious grounds, but there were also those who did not reject the Copernican system on biblical grounds. In the seventeenth century there was much discussion between science and religion in the Northern Netherlands, but that discussion was not followed by censure by the Church of the State. In the Republic there was a large amount of intellectual freedom in the study of the natural sciences, thanks to practical and ideological considerations. In the eighteenth century the seventheenth century tension between science and religion changed into a physicotheological natural science. It was believed that investigations into the workings of nature should lead to a better understanding of its Creator. So Bernard Nieuwentijt in his well-known book: The right use of-world views for the conviction of atheists and unbelievers (1715) intended to prove the existence of God on the basis of teleological arguments.     

Decentring international and institutional famine relief in late nineteenth-century China: in search of the local

This article uses rural gazetteer biographies to examine village and household-level famine relief during the great North China Famine of 1876–9 to deepen our understanding of past relief methods and dynamics at the most local level. Despite the appearance of major works recently on famine in modern China, particularly on the Great Leap Forward, knowledge of Chinese famine relief remains thin and scattered considering the enormity of the subject. Nineteenth-century China saw intensifying international relief activity as well as the emergence of a vibrant charity-relief sector based in China's major cities, leading to the rise of prominent relief institutions in the twentieth century, such as the Chinese Red Cross. But the increasingly intense disasters of China's modern period also saw a surprising persistence of local humanitarian traditions still barely covered by historians.     

Law and Famine: Learning from the Hunger Courts in South Sudan

Activists and scholars are seeking to end famine by promoting international legal accountability for starvation. This article deepens our understanding of the relationship between the politics of famine and law by observing the ongoing prevalence and power of legal norms and institutions during times of famine. It reveals the widespread use of hunger courts in famine-prone South Sudan and their role in legally enforcing social networks that provide for the most vulnerable. Based on analysis of country-wide survey data from 2018 and 2019, qualitative interviews from 2019‒22 and in-depth ethnographic observations of hunger courts in one chiefdom in South Sudan during a period of famine-level hunger in 2018 and 2019, the article argues that hunger courts have played a key role in enforcing social networks. These courts have also supported continuity of chiefs’ authority despite crisis. The article concludes by addressing two issues: whether law is necessarily emancipatory in times of famine, and whether legal norms have shifted responsibility for hunger away from the political economies and conflicts that cause famine, instead placing blame and shame on the families of the most vulnerable.     

Climatology of the middle atmosphere of the Southern hemisphere

Main features of spatial distribution and time variations of meteorological parameters in the Southern hemisphere at altitudes 25–80 km are reviewed on the basis of zonal empirical models revised in 1982. Meridional distribution and seasonal variations are analysed. For comparison purposes with the Northern hemisphere, a model developed by Cole and Kantor in 1978 is used. It is revealed that the compilation of new models of the Southern hemisphere atmosphere has not resulted in substantial revision of hemispheric-structure outlined earlier in studies conducted in the Central Aerological Observatory. Meridional distribution of the parameters in summer is characterized by higher values of temperature, pressure and density gradients in the stratosphere of the Southern hemisphere than in that of the Northern hemisphere. This resulted in greater advancement of the core of the summer-time easterly (low towards the equator in the Southern hemisphere than in its northern counterpart. In winter, meridional temperature gradients in the middle stratosphere are greater in the Southern hemisphere than those in the Northern hemisphere, however, rapid attenuation of the gradients with height is observed in the Southern hemisphere, and above 35–40 km they become negative near 50–60°S, in contrast to positive values typical for the Northern hemisphere stratosphere. In the wind field, specific features of the Southern hemisphere westerly flow are high intensity and relatively low altitude of the maximum speed (as compared to the Northern hemisphere).The phases of the annual temperature wave at low latitudes are similar south and north of the equator; south of 30°S a reversal of the phase is observed. The semi-annual oscillation of temperature and wind is less pronounced in middle and high latitudes of the Southern hemisphere than in the Northern hemisphere.The origin of the primary differences between the hemispheres is related mainly to lower intensity of large-scale stratospheric processes in the Southern hemisphere as compared to those in the Northern hemisphere, which is confirmed by values of the standard deviation of the parameters in the two hemispheres.In summer, temperature and pressure fields based on satellite data are symmetric relative to the poles in both hemispheres. In winter, the distortion of the mean pressure field in the mesosphere may be as great in the Southern as in the Northern hemisphere.     

Dynamics and the ozone distribution in the winter stratosphere : modelling the inter-hemispheric differences

Results from a two year simulation of a General Circulation Model are used to illustrate the main differences found in the lower stratosphere dynamics and the ozone distribution between the Southern and the Northern Hemispheres in winter.The model extends from ground to mesospheric levels with a spectral horizontal resolution up to isotropic wavenumber 42. It incorporates a fully interactive scheme for the ozone mixing ratio which accounts for photochemical sources and sinks, advection by the model winds and coupling with radiative calculations.The model reproduces the large scale inter hemispheric differences quite well, with a very stable and cold vortex in the Southern Hemisphere and a warmer vortex often distorted in the Northern Hemisphere. It is concluded that due to interactions between dynamics, polar stratospheric cloud formation and chemistry, there is a possibility that some stratospheric ozone depletion could be effective in late winter near the night terminator in the Northern Hemisphere, whereas significant ozone depletion only occurs in early spring in the Southern Hemisphere.The importance of synoptic scale dynamics on the ozone transport between the high latitudes and the equator is also stressed. The model develops tongues of ozone-rich air from the high latitudes which are irreversibly mixed at mid-latitudes with tongues of ozone-poor air from the low latitudes. Similar tongues or filaments are clearly visible in the TOMS satellite data. They result from the activity of medium scale-waves in the Southern Hemisphere, whereas in the Northern Hemisphere the larger scale planetary waves play a major role in their development, and their size and extension are larger. It is concluded that transport of the ozone depletion to the mid-latitudes could be more effective in the Northern than in the Southern Hemisphere.     

Cultural traffic in Lübeck and Danzig in the Sixteenth and Seventeenth Centuries

In this examination of patterns of cultural traffic in Lübeck and Danzig in the 16th and 17th centuries it is argued that while Danzig was strongly influenced by Dutch commercial contacts and exercised a very strong cultural influence on its Polish hinterland, Lübeck was open to a more diffuse range of external cultural influences, and competed as a centre of culture with its neighbours. Two assumptions are tested here: that a relationship existed between cultural innovation based on external stimuli and levels of commercial prosperity in cities, and that the more passive a city became in terms of international trade, the more it was influenced by external cultural trends. It is concluded that the cultural experiences of the two cities were shaped as much by their relationship with their hinterlands as they were by changing patterns of international trade during the 16th and 17th centuries.

Elastic labor supply and agglomeration

This study analyzes the interplay between the agglomeration of economic activities and interregional differences in working hours, which are typically longer in large cities, as they are normally more developed than small cities. For this purpose, we develop a two‐region model with endogenous labor supply. Although we assume a symmetric distribution of immobile workers, the symmetric equilibrium breaks in the sense that firms may agglomerate when trade costs are intermediate and labor supply is elastic. We also show that the price index is always lower, while labor supply, per capita income, real wages, and welfare are always higher in the more agglomerated region.     

Graduated sovereignty and global governance gaps: Special economic zones and the illicit trade in tobacco products

Illicit trade in tobacco products has been a significant problem globally for many years. It allows cigarettes to be sold far below their legal price and thus contributes to higher consumption, morbidity and mortality, and deprives state treasuries of a substantial amount of revenue. This article identifies special economic zones (SEZs), particularly free trade zones, as a key conduit for this illicit trade. The development of SEZs as weak points in the global governance architecture is explained with reference to the concept of ‘graduated sovereignty’, whereby the uniform management of territory by modern states has given way to a more spatially selective form of territorial governance, in which some slices of territory are more fully integrated into the world economy than others via various forms of differential regulation. Attempts to comprehensively (re)regulate SEZs, in the face of growing evidence of the dysfunctionalities that they can engender, have so far been unsuccessful. It is concluded that the neo-liberal global economy has facilitated a regulatory ‘race to the bottom’, a problem that can only ultimately be overcome by international negotiation and agreement.     

The Return of Zipf: Towards a Further Understanding of the Rank-Size Distribution

We offer a general-equilibrium economic approach to Zipf's Law or, more generally, the rank-size distribution—the striking empirical regularity concerning the size distribution of cities. We provide some further understanding of Zipf's Law by incorporating negative feedbacks (congestion) in a popular model of economic geography and international trade. This model allows the powers of agglomeration and spreading to be in long-run equilibrium, which enhances our understanding of the existence of a rank-size distribution of cities.     

南北朝的客馆及其地理位置

客馆为传统中国外交上的重要机构,由地主国设立,以接待归附者、使节、人质、入朝藩王、沙门与留学生等各种不同身分的外国人,试图落实招抚荒远、万国宾服的理想。南北朝时,客馆在数量与规制上有明显的发展,它除了解决外国人的食宿需求,也是重要的外交折冲场所。南北朝的客馆乃是拥有许多馆舍,颇具规模的馆区。客馆的方位受到城市格局变化的影响,南北朝以后,多位于城南。其地理位置也从城郭外向宫城靠近,且通常位于南北中轴线的通衢上。     

Geneva's future: reflections on the role of a values‐based city

In a world where most of the great cities are heavily branding themselves to compete for lucrativebusiness, political and sporting events, what future role is there for an international values‐based city like Geneva? This article reflects on the history of ideas that have taken root in Geneva over the centuries and suggests how they might be actively re‐positioned to give the city continuing relevance in the coming century. It looks at eleven political and practical ideas that have hadimportant manifestations in Geneva and have been embodied in some of its international organizations, notably: freedom of movement; free thinking; political self‐determination; compassionate warfare; peace and trade among others. It then argues that, in order to survive as a leading international city, Geneva must develop real expertise on these big‐hitting political issues, improve its ability to deliver on them and create a dynamic alliance of other internationalist valuesbased cities around the world which can mobilize similar concerns and embody a similarly Genevan model of international space.     

北宋长干寺圣感塔地宫形制成因初探

2008年发现的南京北宋长干寺圣感塔地宫形制为圆形竖穴土圹式,为目前发现宋代舍利塔地宫中所仅见,而与南北朝时期的早期佛塔地宫形制一致。通过全面梳理我国舍利塔地宫的发展脉络,以及南京长干寺自东吴开始的建塔历史,可以认为北宋长干寺圣感塔地宫独特形制的形成有两种可能性:其一是沿用六朝长干寺佛塔地宫,其二是北宋建塔过程中有意模仿南北朝时期的地宫形制。
