The minor rural aristocracy and great lords in thirteenth-century Tuscany: three cases from the entourage of the Guidi counts

This article examines relations in thirteenth-century Tuscany between the minor rural aristocracy and great rural lords, that is, those based outside cities. The subject is approached through a study based on three families, with special emphasis on the way they were bound to the extended family of the Guidi counts, who were prominent at the highest level in the thirteenth-century kingdom of Italy. In the thirteenth century, attendance on the counts was not attractive to families of the minor aristocracy: it was universally acknowledged that the great rural lords of Tuscany had little to offer their adherents in terms of wealth, power and prestige, incentives which could be obtained from the cities of the region. Minor aristocrats who chose to live as professional soldiers were particularly attracted to the cities, which were always in need of soldiers for their armies.     

自然与城市历史的缠绕--草海之城堪萨斯城的变迁

堪萨斯城崛起于密苏里河与堪萨斯河的交汇处,是一个依赖大平原的农牧业所建立的美国中西部都市。铁路助力资本打破了自然的种种限制,令大平原转化为堪萨斯城的腹地。虽然征服自然以实现城市经济的永续增长,一直是堪萨斯城,乃至整个资本主义制度与经济文化的野心,但是成为腹地并不意味着自然完全受到资本与技术力量的操纵,更不意味着自然的消失。作为一种自发的、独立的力量,自然以其丰饶奠定城市发展的基础,也以其极限挑战着城市发展的野心和规划。在堪萨斯城的故事中,1930年代的尘暴与1951年的洪水以灾难的形式迫使这个城市去适应新的生态现实。     

季节时空交互视角下老年人公交移动性的影响因素研究——以芜湖市为例

公共交通是我国老年人出行的主要交通方式之一,公交移动性是衡量老年人生活质量和幸福感的重要指标。从季节和空间双重维度分析老年人公交移动性的影响因素有助于深入理解老年人出行行为机制。利用公交刷卡数据和地理探测器方法分析了季节时空因子对老年人公交移动性的影响。研究发现：①不同季节中空间因子对老年人移动频率、移动半径和移动熵的解释力和显著性存在明显差异,对老年人移动性影响机制的分析应考虑时空变化的双重影响;②不同空间因子之间以及季节与空间因子之间的交互作用可以显著增强对老年人移动性空间分异的解释力,考虑多个因素的协同效应对深入理解老年人行为有一定帮助。研究试图拓宽老年人移动性影响因素的分析思路,为老年宜居城市建设和城市移动性规划提供重要支撑。     

南宁市房地产价格分布规律的机助制图研究与开发方向的探讨

南宁市房地产业经历了由沉寂、复苏、火爆到稳步发展的过程．各公司开发的房屋类型相近,但价格差异却很大,价格分布呈现明显的规律性：一是城市中心价格高,边缘与郊区价格低;二是东部城区价格高,西部城区价格低．主导价格分布规律的三大影响因子是地理位置、交通便捷程度和生态环境质量．南宁今后的房地产开发和城市规划建设一要顺应价格分布规律,优地优用、保障房地产开发的高效益;二要加强交通设施建设和环境保护．促进全市房地产的升值;三要因势利导,发展城市副中心,逐步形成多中心的城市建设格局。     

北大藏秦水陆里程简“阳”县考辨

北京大学入藏的秦代水陆里程简册中记载秦代有"阳"县存在,关于这一新出现的秦县,前辈学者认为可能是位于今河南省方城县的秦汉"阳城"。然而,从简册中记载的"阳"县下属各乡到其他地区的距离来看,"阳县"不太可能在今方城附近,而更有可能是位于先秦"唐"国故地的"唐"县。其他出土材料所见的"唐"县一般写作"阳",清华简《系年》中还有楚国曾灭"唐(阳)"置县的明确记载。秦代的阳县应该就是继承了楚灭唐国之后所设的阳县。     

浙江宁波镇海鱼山遗址Ⅰ期发掘简报

鱼山遗址位于浙江省宁波市镇海区九龙湖镇河头村,东距现海岸线直线距离约7.3公里。2013至2014年,宁波市文物考古研究所等单位对其进行了Ⅰ期发掘,分别发现河姆渡文化、良渚文化、商周和唐宋等四个不同时期的文化遗存。其中河姆渡文化二、三期,良渚文化晚期和商周时期堆积之间的自然淤泥层,对于研究沿海地区史前至商周时期文化面貌、人地关系等基础性问题提供了一批重要资料。     

City branding in polycentric urban regions: identification,profiling and transformation in the Randstad and Rhine-Ruhr

In polycentric urban regions several distinct cities, none of which is dominant, cooperate and compete with each other to attract inhabitants and firms. In such settings city branding strategies do not solely affect one city, but the entire region. We examined how city branding in the face of ecological modernization, that is, delivering higher added economic value, while lowering environmental impacts, is playing out in the Dutch Randstad and the German Rhine-Ruhr. Our findings show that regional identity formation occurs at the sub-polycentric urban region level, coinciding more with (historical) economic profiles than with planning imaginaries. The Dutch cities profile themselves more along the lines of ecological modernization than their German counterparts. Differences between subregions within each polycentric urban region are also noticeable, where more industrialized regions, such as the Ruhr or southern Randstad focus on ‘green’, ‘liveable’ and ‘knowledge-oriented’, while cities with stronger knowledge-intensive sectors portray themselves as ‘smart’ or ‘sustainable’. Cities generally substantiate their profiles through projects, but a significant gap persists between reality and aspirations for improved environmental conditions. This is especially true for the Dutch cities, where many claims, but little visible action can be observed.     

Polycentricity as spatial imaginary: the case of Helsinki City Plan

The paper analyses with a case study the use of a widely applied normative concept of polycentricity as spatial imaginary. The case study of Helsinki City Plan and the conflict over its city-boulevard scheme draws on qualitative content analysis of planning documents and expert interviews. It demonstrates the instrumental role of multiple interpretations of polycentricity in tension-ridden metropolitan and city-regional spatial planning. The conflict reveals how the conceptual ambiguity of polycentricity and the institutional vagueness of city-regional planning have together enabled advancing contradictory political aims under their guise. In conclusion, the paper emphasizes the persuasive performativity and fluidity of polycentricity as a spatial imaginary in multi-scalar planning settings.     

定州汉墓竹简《论语》研究概述

1973年,考古工作者在河北定州八角廊村40号汉墓之中发现了大量竹简,其中包括许多《论语》残简。这是我们目前所能看到的最早的《论语》白文版本,也是目前唯一能够见到的《论语》的西汉抄本原件,是《论语》出土文献的代表。学者们通过对此简本深入细致的研究,得出了许多新见解。
