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.     

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。     

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。     

唐玉门关地望新探——基于历史文献与考古遗存互证

在实地调查的基础上,根据传世典籍和出土文献的记载,结合年代测定、考古发现和遥感影像资料,通过空间分析,作者认为唐玉门关和墨离军驻地应在河西走廊西段的常乐故城,即今瓜州县“六工古城”遗址。这里是丝绸之路的交通枢纽,是西域出入口的重要关卡,亦即北魏时期新开伊吾道的起首。唐代玉门关地处疏勒河和榆林河下游洪积冲积扇缘的古绿洲,地貌和水资源等地理环境因素是制约关城选址的基础条件,而政治、军事等人文地理因素则是决定玉门关时空变迁的关键。

郑汴一体化背景下开封旅游业发展研究

作为一座具有2700多年历史的文化名城,开封旅游业发展取得了不小的业绩;但如果从总体上衡量,开封的旅游发展还处于初级提升的景点经济阶段.＂十一五＂规划中的郑汴一体化战略将为开封旅游的繁荣提供重大的发展机遇.面对机遇,开封应该调整旅游发展战略,依托郑州庞大的客源市场和便利的交通优势,改革景区（点）机制、筹建文化大市场、净化旅游大环境、建立强有力的旅游管理体制、进一步明确旅游城市定位,争取在规划期内实现开封旅游经济的全面振兴.
