社区生活圈公共服务设施配置的空间分异分析——以大连市沙河口区为例

城市公共服务设施的配置水平直接影响到居民的生活品质。论文基于高德地图获取的地图数据,使用城市网络分析工具(Urban Network Analysis Toolbox, UNA)对大连市沙河口区内的6类公共服务设施分布进行空间分异分析,并对区内90个社区的居民出行可达设施的数量及类别进行测度,最后对各个社区进行总体评价。结果表明：① 大连市沙河口区公共服务设施空间分布不均,北多南少,呈现出“一主多次”的“廾”字形的结构,主要分布在西安路商业区周边和各个街道的次级商业区;② 居民可达设施数量空间差异大,北多南少,各街道均有1或2个区域可达设施数量较多;③ 居民可达设施类型数量存在一定差异,70%以上的住宅楼中的居民可以获得全部6类公共服务设施;④ 各社区居民可达设施总体处于差异较小的均衡状态,但仍有个别社区存在内部差异较大的现象。设施的分布、地物的阻隔和社区的封闭程度对居民获取各类公共服务设施影响较大,建议构建“设施完善、便捷可达”的15 min社区生活圈。     

2010—2015年中东北非政局变动中的“政治性民意势力”及其影响

援引批判地缘政治学话语权和地缘政治想象分析方法,在对“民意”“政治性民意”“政治性民意势力”内涵界定的基础上,分析了2010—2015年中东北非地区相关国家政局变动中“政治性民意势力”的形成背景、过程及其影响。结果表明：中东北非国家“政治性民意势力”的形成有着深厚的国内背景和复杂的国际背景;“政治性民意势力”的形成经历了从民意事件客体的呈现,到民众聚集并上升为政治性议题,再到国内外势力借力博弈形成挑动抗议、推动政变的政治力量的过程;“政治性民意势力”形成以后,多行为体借力博弈下,在国别、区域上呈现不同的扩散轨迹和规律;“政治性民意势力”一方面造成了中东北非相关国家的政局变换,另一方面则推动区域地缘政治格局的变迁。这是对民意事件的地缘政治理论解读和分析,是一次较为有意义的尝试。

The Public Is Intellectual

This article is a discussion and critique of public intellectualism in the present. Rather than reify a self-aggrandized form of public intellectualism within academia that centers individualized intellectual development and that encourages a greater flow of findings outward to communities, I highlight black women public intellectuals who have used their skills, talents, and station within the university and society in novel ways. Moreover, I suggest that scholars take seriously the questions, research methods, and analyses emerging from the general public, particularly from within communal and political organizations. These encouragements are illustrated by highlighting three political education workshops that have been developed across the United States.     

The Relationship between Narratives,Wildlife Value Orientations,Attitudes, and Policy Preferences

Overabundance of white-tailed deer is a pervasive problem across the United States. Deer are blamed for increased risk of auto accidents, tick-borne diseases, and overbrowsing of native species. Lethal management techniques, cited as cost-effective and humane, are commonly employed for herd management. However, the approach frequently sparks outrage among various stakeholders who feel killing of animals is unjustified and prefer nonlethal measures. Wildlife managers then face the challenge of communicating with the public to build policy support for lethal management. The Narrative Policy Framework was used to test the effects of differing narratives on public opinion for lethal deer management. Results indicated narratives were influential in shifting attitudes toward and support for a proposed sharpshooting policy even in some cases where respondents were already familiar with the issue and held a previous opinion. This study also supported the utility of the Narrative Policy Framework for examining human dimensions of wildlife issues.     

基于手机数据的城市公共空间活力评价方法研究——以南京市公园为例

针对已有公共空间活力评价方法存在视角单一,对活力多样性体现不足的问题,本文在深入理解活力内涵与特征的基础上,探讨了多维视角下的公共空间活力评价方法。从个体行为、空间活动、空间交互联系网络的复合视角,围绕活力的核心,综合考虑活动类型及空间联系,提出了重访性、混合性、网络交互中心性三项测度评价指标,在此基础上构建了公共空间活力评价方法框架。以南京市公园为例,采用手机大数据,进行了公园活力的综合评价。分析表明：手机数据可从多个维度快速准确的识别城市公共空间活力现状,并展开综合评价。同时,可进一步参照活力不同维度特征的测度结果,提出具有针对性的活力营造及提升策略与路径指导,体现了本方法对已有评价方法具有一定修正和延展作用。     

A study of coral reef resilience and implications of adaptive management and rehabilitation in Khanh Hoa Province, Vietnam

The Province of Khanh Hoa, Vietnam, is located in the western South China Sea and boasts a shoreline of 385 km and many islands. Previous studies have indicated the extreme diversity and abundance of coral reefs in its waters as compared with other coastal provinces of Vietnam. A study on the resilience of coral reefs against increased surface water temperature and anthropogenic impact is conducted at 19 reef sites in 2015. At each site, a series of parameters (e.g., coral covers, genus diversity, and coral recruitment, substratum heterogeneity, depth, water exchange level, and sediment deposit and water temperature) are measured quantitatively or semi-quantitatively. The measured data are rated based on the relationship between the parameter values and coral susceptibility; the consideration that reef health reflects the biological capability to adapt to environmental changes and the recruitment potential if bleached; and positive or negative influences of physical factors in the mitigation of thermal stress and protecting corals from bleaching. A cumulative analysis enables researchers to divide the studied reefs into four categories based on varying levels of reef health to support resilience, recovery, and vulnerability in the case of increased water temperature. Relevant management interventions for each category and other supporting activities are suggested to enhance management effectiveness and to plan the rehabilitation of coral reefs for biodiversity conservation and touristic development, taking into account the involvement of related stakeholders.     

兼顾志愿者地理信息的国家应急测绘公众服务平台设计
