居民跨界行为的边界研究：以珠澳边界意义重构为例

研究探讨了边界的物理形态及其空间意义,并讨论由跨界行为催生的地方感与地方意象及其对边界空间意义的重构。以珠澳边界（拱北口岸）为案例地,本文主要采用追踪和访谈的研究方法,研究发现：跨越珠澳边界的行为（尤其是由珠海往澳门方向的跨界行为）以个人消费为主,主要包括购物、娱乐和餐饮等,而与之联结的消费地点也大同小异,但也存在不同时代和社会阶层因素对于跨界活动目的的影响,且流动性往往与特定的地方联结,使原有的固定行政边界及其所规定的空间管制逐渐被打破。出于满足生活的需求、社会互动的情感联系,抑或是出于追求地方价值的体验和情感表达,跨界主体成为塑造边界两边地理想象的重要因素,地理想象与现实生活空间的差异形成了想象的边界并间接地作用于珠澳边界空间意义的重构。     

澳门居民对“自由行”政策支持意向研究:地方依恋的调节作用

居民态度是影响旅游地持续发展的关键因素。借助态度ABC模型的标准学习层级理论,运用结构方程模型研究澳门居民对自由行政策支持意向的形成机理,并对地方依恋在其中的调节作用进行验证。结果表明：澳门居民对自由行政策支持意向主要受正面影响感知和积极情感的影响,澳门居民对自由行政策的经济与社会作用感知能激发其对旅游发展的满意感,并抑制对内地自由行游客的厌恶感,社会成本感知将导致居民对自由行游客的厌恶感,居民满意感对其支持行为意向有显著正向影响,地方依恋在澳门居民态度形成过程中发挥部分调节作用。根据研究结论,提出了提升澳门居民对自由行政策支持意向的管理举措。     

迁居意愿、地方依赖和社区认同——北京中关村地区居住选择调查分析

迁居行为及其意愿反映了城市居民对美好生活的向往,揭示了城市居住环境是否能够满足居民的需要。论文从迁居意愿的视角,将地方依赖和社区认同引入迁居研究中,并采用问卷调查和访谈相结合的方法来分析城市居民的居住选择。运用Williams量表,在292份调查问卷和52份深度访谈的基础上,对北京中关村地区展开了调查研究。结果表明：中关村周边社区居民对就业和子女教育具有明显的地方依赖和较高的社区认同感。在292名被调查者中,共有115名居民有迁居意愿,占被调查者总数的39.4%。其中,在就业和子女教育地方依赖程度较低的调查人群中,这一比例分别上升至47.2%和54.2%。此外,有迁居意愿的居民大多社区认同感不高,在115名有迁居意愿的居民中,仅有4人对所在社区具有强烈认同感。论文从地方感的角度丰富了居住空间的研究内容,为理解当代城市居住空间的特点、提升城市空间建设质量提供了参考依据。     

反射波法检测水泥搅拌桩的可行性和方法研究

水泥搅拌桩作为桩基础的一种特殊形式,在软土地基地区已被广泛应用。由于其桩身纵波波速远低于混凝土桩的波速,且长径比一般较小及桩身均质性等问题,所以应用于混凝土桩的小应变反射波检测方法是否可以应用于对水泥搅拌桩进行检测,在测桩界尚存在分歧意见。作者从理论上分析了反射波法的本质,指出波阻抗差异,分辨率和波长的关系是反射波法的要害。本文讨论了长径比的实际意义及其与一维波动理论的关系．提出了水泥搅拌桩“桩身质量“的新观点。从理论分析和实际检测结果资料的讨论出发．肯定了反射渡完全可以对水泥搅拌桩进行检测,并总结了实际检测过程中的方法技术。     

Numerical simulation and seismic performance evaluation of buried pipelines rehabilitated with cured‐in‐place‐pipe liner under seismic wave propagation

The cured‐in‐place‐pipe (CIPP) liner technology involves installation of flexible polymeric composite liners coated with thermosetting resin to the inner surfaces of existing buried pipelines. This innovative technology provides an efficient, economic, and environmentally friendly alternative for rehabilitation of structurally compromised underground pipelines without expensive and disruptive excavation. However, the lack of analytical/numerical procedures to quantify the seismic performance of CIPP liner reinforced pipelines remains a barrier to the seismic design and rehabilitation of underground pipelines. This paper first develops an experimentally validated hysteretic model of ductile iron push‐on joints, reinforced with one particular type of CIPP liner under repeated axial loading. A numerical procedure is then proposed to systematically assess the seismic performance and fragility of straight buried pipelines incorporating push‐on joints and subjected to transient ground deformations. The numerical results indicate that CIPP liner‐reinforced pipelines exhibit favorable robust seismic performance with limited joint damage under high‐intensity transient ground deformations.

过去千年中国不同区域干湿的多尺度变化特征评估

依据近年发表的新成果,对中国过去千年干湿的年至百年尺度变化特征进行了总结梳理与对比分析,综合评估了20世纪干湿变幅的历史地位。主要结论是：① 根据历史文献记载重建的东中部各区干湿序列在1400年以后均达高信度,但其前因存在记录缺失,仅有半数时段的重建结果达高信度。在东北及内蒙古东部,根据不同地点湖沼沉积物记录揭示的区域干湿百年尺度变化特征在多数时段不一致。在西部的黄土高原、河西走廊、新疆中北部、青藏高原东北部和东南部等地区,利用不同地点树轮资料重建的干湿序列显示的干湿变化特征在区内一致性高。② 过去千年中国各地干湿变化均存在显著的年际、年代际和百年尺度周期。其中准2.5 a、60~80 a和110~120 a等尺度的周期为所有地区共有;3.5~5.0 a、20~35 a等尺度周期则主要发生在东北、东中部地区、黄土高原和青藏高原;而准45 a周期则只发生在东北和东中部地区（均超过90%信度水平）;各区域间的干湿变化位相并不同步。③ 尽管已发现青藏高原东北部20世纪很可能是过去3000 a最湿的世纪之一,但其他大多数区域的重建结果显示：20世纪的干湿变幅在年代际尺度上均未超出其前各个时段的变率范围。     

地方品质驱动新时期中国城市创新力时空演化

针对2001—2016年中国地级市地方品质驱动创新力时空演化格局的研究表明：① 2001年来地市创新力差异趋于持续扩大,且呈明显的阶段性变化,创新力差异自2008年来趋于缓慢下降,而创新力空间集聚性不断增强。② 东部沿海地市存在稳定提升创新活力的多邻域创新极,中西部高创新力地市多位于经济实力较强的区域中心。③ 地市创新力演化存在固着的“核心?边缘”空间结构,且呈现出时变的累积与惯性效应,创新高增长协同发展态势整体较弱。④ 地方服务品质、消费品质、信息化水平、基础设施及医疗服务品质对创新力具有重要影响,地方环境品质、交通便利和吸纳外资品质的影响程度较弱。     

Place ‘From One Glance’: the use of place in the marketing of New Zealand and Australian wines

Associations between place and wine are historically deep. Past and current narratives of wine production are wedded to environment attributes of particular places, and in both the European and Australasian settings this has been codified by way of formal labelling requirements for the place of origin for wines. In this paper we explore the role of place references on the front labels of Australian and New Zealand wines through a small initial survey. The results reveal that the importance of place references is stronger for New Zealand wines. We argue that this reflects strongly the very different structures of the industries in the two countries, with the emphasis for New Zealand producers on high-quality wines for which origin statements are expected as opposed to the Australian focus on the production of bulk, value-driven wines dependent on the blending of wines across regions and places. This in turn has implications for the future development and marketing trajectories of the two industries.     

An Analysis of the Relationship between Residents' Proximity to Water and Attitudes about Resource Protection*

This article investigates attitudes toward water resource protection among residents in varying proximities to resources, specifically to identify attitudinal differences and the extent to which nearness and adjacency explain attitudes. Proximity was evaluated by measured distances using GIS and reported closeness from a mail survey. Five attitudinal dimensions were assessed: general importance of resource protection, support for government, regulations, and economic measures, and combined overall attitudes. Nearness to water was most significant in explaining economic support, and adjacency for generally expressed importance. Attitudes differed most toward regulations. Overall, the relationship appears nonlinear. Empirical findings have implications for resource management, especially equity criteria in decision making.     

Sheinkin as a place in the globalizing city of Tel Aviv

Sheinkin is an example of a place constituted by global forces. Yet Sheinkin creatively responds to scalar jumps of global forces, drawing from the capitals of the global system like Soho and Greenwich village. These models are embedded in the Israeli reality with Sheinkin becoming an incubator of post-Zionist identity. Young people from all over Israel concentrate in the place on Fridays to participate in choreography of strolling along the street with its’ designers’ shops, mingling with celebrities and others who belong to the cult and around the ‘Hyde Park’ corner in which environmental, spiritual and other worldviews are promoted. The article suggests a model to investigate such places as the organic integration of a community whose participants do not live in the place but pilgrimage to the place, a landscape that appraises creativity, originality and individualism, a choreography of strollers who search for stimulations and a set of norms and values promote in the place.
