中国—中亚合作冲突关系及时空热点分析

中亚地处欧亚大陆中心，是“一带一路”倡议建设的重要区域。本文基于GDELT新闻媒体数据库，构建了事件影响度和双边关系度，定量分析了中国与中亚国家之间的合作、冲突关系演变，采用时空热点分析识别了中国在中亚城市尺度的合作、冲突热点模式。结果表明：①中国与中亚国家的合作日趋紧密。“一带一路”倡议提出之后，中国与中亚国家的合作趋势显著上升，与哈萨克斯坦的合作关系最为紧密。②中国在中亚地区的合作区域集中在中亚国家首都、战略要地、重要能源基地等，在乌兹别克斯坦安集延地区和塔吉克斯坦哈特隆州形成集中连片的合作区域。冲突区域集中在中亚国家首都和战略要地，与合作区域在空间上高度重合，但影响力显著低于合作事件。③中国在中亚城市的影响力以合作关系占主导，冲突关系大于合作关系的城市主要分布在吉尔吉斯斯坦。64%的中亚城市为低合作—低冲突状态，中亚国家首都、阿拉木图、安集延属于显著的高合作—高冲突城市。④时间尺度上，中国与中亚地区的合作热点以持续型为主，冲突热点以振荡型为主，哈萨克斯坦纳伦市、阿特劳州为新增冲突热点，应引起重视。     

南京国民政府时期的地籍测量及评估——兼论民国各项调查资料中的“土地数字”

地籍测量是南京国民政府时期土地行政的一项重要措施,然而由于各种主客观原因,这项措施只在部分地方施行,成果有限,长期以来没有得到学界的重视。本文从制度层面对南京国民政府时期的地籍测量进行初步梳理,考察其在全国的总体完成情况,并以江苏省句容县为个案,对其绘制的地籍图进行分析。在此基础上,以杭市县、平湖县的地籍测量数据对民国时期各项土地调查数字进行再评估。     

REPRODUCING AND RESHAPING ETHNIC RESIDENTIAL SEGREGATION IN STOCKHOLM: THE ROLE OF SELECTIVE MIGRATION MOVES

This paper deals with the issues of selective migration moves, and the production and reproduction of immigrantdense neighbourhoods in Stockholm, Sweden. It has been shown earlier that selective migration, that is, socioeconomic and ethnic differences between those leaving, entering and staying in so‐called deprived neighbourhoods, reproduces these neighbourhoods' characteristics of being poor and immigrant dense. Key concepts launched to inform such studies and derived from the US segregation discourse are “white fight” and “white avoidance”, meaning that native people (or white people in the US case) tend to leave neighbourhoods experiencing growing numbers of immigrants (black people) and which they also tend to avoid moving into such neighbourhoods. Using a complete set of geo‐coded longitudinal individual data for the 2005–2008 Stockholm County population, this paper contributes to our understanding of ethnic differences in the intra‐urban migration system. Three empirical questions are addressed: what individual characteristics distinguish (1) those who move into neighbourhoods experiencing rapidly increasing immigrant densities from those moving elsewhere in the urban region; (2) those who leave neighbourhoods experiencing rapidly increasing immigrant densities from those who stay put; (3) those who move in the direction of higher immigrant densities from those moving into lower densities? Results from multivariate statistical analyses provide support for the avoidance hypothesis but less support for the fight hypothesis. When controlling for a range of individual and neighbourhood attributes there is clear evidence that native‐born Swedes are less inclined than most immigrant categories to move into immigrant dense areas while ethnic origin does not seem to matter much when explaining who leaves such areas.     

Digital containment and its discontents

This essay explores a set of existential risks that accompany digital storage capacities, devices, and promises: the anxious exhaustion of digital housekeeping; the disorientation of self-archiving; and the annihilating sense of loss that strikes when digital containment fails.     

The philosophical systems of Francesco Patrizi and Henry More

ABSTRACT

This paper presents a comparison of the philosophical systems of Francesco Patrizi and Henry More. The point, however, is not to demonstrate Patrizi’s influence on More but rather to see how, with respect to some particular subjects, they both tried to offer a modern interpretation of Neoplatonism. The main axis of the analysis follows the topics of space, light, and soul. While to More, light is of merely marginal interest, it is demonstrated that space and soul are of crucial importance and play a similar role in both authors’ systems. They function as intermediary entities that link the higher and the lower reality and form a sort of canvas upon which the material world unfolds. Yet, in comparison with Patrizi, More’s system is both constrained by a much stricter, dualistic classification and at the same time veers dangerously close to immanentism and pantheism (which More tries to avoid).     

Applied spatial modelling in the twenty-first century: the Wilson legacy. Looking back and looking forward

ABSTRACT

In this paper, we review the contributions of Alan Wilson to geography and regional science over a period of more than 50 years. Beginning from theoretical insights, mathematical models and spatial analytics methods for cities, the research becomes somewhat more applied in the 1980s. The notable impact of this work in a business and commercial setting is in marked contrast to a relative lack of traction in a public policy environment. Reasons for this are explored. In more recent times, the advent of big data has started to generate transformational approaches to geographical problems. We argue that years of accumulated experience from the study of more abstract problems within less well-instrumented systems was a precursor to this. Finally, we argue that through working with a ‘family’ of modellers, the skills available to meet these challenges is significantly more extensive than could have been the case in the absence of such a programme. It is a legacy which is at once inspiring, durable and hugely significant.     

DETERMINANTS OF IMMIGRANTS’ ENTRY TO HOMEOWNERSHIP IN THREE NORDIC CAPITAL CITY REGIONS

The extent of homeownership among immigrants may be seen as an indicator of integration and as a determinant of ethnic residential segregation. Studies have shown differences in the determinants of homeownership between immigrants and natives, indicating that variation in homeownership is not only a function of differences in economic resources. These studies have largely focused on Anglo‐American contexts, using mostly cross‐sectional data. We apply survival analysis methods to analyse the determinants of entry to homeownership in the capital regions of three Nordic countries – Denmark, Finland and Sweden – utilizing longitudinal individual‐level register‐based datasets. We find that differences in entry to homeownership between natives and different immigrant groups cannot be explained by differences in socio‐economic background factors. We also find differences in the effects of these factors. Effects of income are generally weaker among non‐Western immigrants and immigrants are less responsive to changes in household composition. The share of non‐Western immigrants in the neighbourhood is only weakly related to entry to homeownership, while immigrants and natives living in public rental housing tend to be slightly less inclined to move to homeownership. Weaker income effects among immigrants, weak effects of ethnic segregation and the importance of the public rental sector differentiate our results from earlier findings. Weaker income effects may indicate that uncertainty about the future also affects middle‐income immigrants. Differences between the three contexts in housing markets and policies do not seem to matter much, although the results indicate that difficult access to the private rental sector may push immigrants to homeownership.     

Population density and the accuracy of the land valuations in the 1798 federal direct tax

Abstract

The peculiar operation of the 1798 federal direct tax has led scholars to question whether tax officials reported the land valuations from their districts faithfully. Peter Lindert and Jeffrey Williamson argue that southern tax assessors systemically under reported the value of southern real estate, and they adjust their income estimates to account for the likelihood of corruption. This paper affirms the reliability of the tax returns by demonstrating that population density, rather than corruption or lax enforcement, can explain nearly all of the variation between the assessment districts. Accepting the tax valuations as accurate would lower Lindert and Williamson’s income estimates, imply slower growth rate between 1774 and 1800, and suggest a higher growth rate between 1800 and 1850.     

基于多源数据的兰州市主城区城市职住空间关系研究

随着中国经济转轨和社会转型，“职住分离”日趋严重，导致城市出现了一系列问题，急需对新的职住关系进行检视。职住关系研究的难点在于如何有效地锁定居住地、工作地，以及居民如何在居住地-工作地之间位移、居住-就业的空间匹配关系。论文以百度POI大数据和热力图为支撑，辅助问卷调查，结合兰州市土地利用现状图，综合应用职住比模型和最近距离等分析方法，多尺度刻画了兰州市主城区的职住关系。结果表明：在城区尺度上，兰州市职住关系总体处于平衡状态，职住平衡型占99.40%，居住倾向型和就业倾向型分别仅占0.12%和0.48%。从城市核心区到边缘区，职住失衡逐渐加重。职住平衡更多地体现在单位型社区上，失衡主要由商业型社区引致。在街道尺度上，职住关系差异明显，绝大多数街道处于职住平衡状态。城市核心区街道以“就业倾向型”为主；边缘区街道表现为“居住倾向型”。
