ULTRA-Ex: Collaborative Research: Urban Sustainability and Push-Pull Drivers of Residential Change: Washington, D.C., Baltimore, Maryland, and the Chesapeake Bay

本研究探讨的问题是：“环境修复与都市更新之间的关系是什麽？“更具体地说，这项研究调查了1）城市可持续发展政策，投资和成果之间的关系; 2）城市化的驱动因素; 3）城市居民区的长期动态。将使用三个相互关联的主题来审查这些关系：a）城市森林和开放空间，B）环境质量，和c）媒介传播疾病。这些研究主题的背景下，考虑到气候变化和环境正义的脆弱性的框架。为了回答这些问题，本研究讨论了几种类型的机会，在理解城市系统的理论进步。传统的社会分析包括几个“推拉”因素，如犯罪，政府服务差，高税收;昂贵和恶化的住房;小建筑地段，种族紧张局势;但很少强调环境参数。该项目介绍了一种新的方法，推挽式驱动器的分析，结合环境参数，特别是在一个很好的分辨率。除了研究长期的，社会生态的推拉变化随着时间的推移，这个项目探讨了泛政府的方法来理解环境修复和城市振兴之间的关系，在邻里水平的效用。这个项目探讨了从一个阶段到另一个阶段的邻里变化的动态理解：是什么原因导致邻里衰落？是什么促使社区重组、振兴和繁荣？还审查了变化的各个方面。关注缓慢和快速变化的变量，关注变化和持续性，对应于对变化类型和速度的兴趣。将采用多种类型的数据和分析，包括高分辨率遥感数据、长期人口普查数据、地块级地籍数据、关键线人调查、水和空气采样以及微生境分析。除了这些数据和分析，三个研讨会-每个研究主题一个-汇集了DC-BC ULTRA社区的所有成员。这些讲习班形成了一个实践社区，围绕着公正、可持续的城市的理念，并为支持者之间的互动和与多个团体交流研究成果提供了机会。 该项目采用了一个完全整合的研究-教育-推广模式，包括研究人员，学生和决策者。研究人员和管理人员在一个完整的研究应用周期中进行合作：a）确定问题，B）收集新数据并共享现有数据，c）分析数据，d）解释结果，e）应用研究结果，f）确定新问题。学生通过课程学习相关内容，并通过有偿奖学金，实习和顶点或论文项目继续从事该项目。学生从班级和整个DC联盟和大学在巴尔的摩地区招募申请支付超研究奖学金。ULTRA研究员直接与研究人员和项目经理合作，参加ULTRA研讨会，并为手稿做出贡献。在自然科学和社会科学，从基础研究到应用实习的广泛机会旨在吸引不同的学生群体和不同的兴趣。

This research addresses the question, "What is the relationship between environmental rehabilitation and urban revitalization?" More specifically, this research investigates the relationships between 1) urban sustainability policies, investments, and outcomes; 2) drivers of urbanization; and 3) long-term dynamics of urban residential neighborhoods. Three inter-related themes will be used to examine these relationships: a) urban forests and open space, b) environmental quality, and c) vector-borne diseases. These research themes are contextualized in a framework that considers vulnerability to climate change and environmental justice. To answer these questions, this research addresses several types of opportunities for theoretical advance in understanding urban systems. Traditional social analysis incorporates several "push-pull" factors such as crime, poor government services, and high taxes; expensive and deteriorating housing; small building lots, and racial tension; but there is little emphasis on environmental parameters. This project introduces a novel approach to push-pull driver analysis by incorporating environmental parameters, particularly at a fine resolution. In addition to examining long-term, social-ecological push-pull changes over time, this project explores the utility of a panarchy approach for understanding the relationship between environmental rehabilitation and urban revitalization at the neighborhood level. This project examines the dynamic understanding of neighborhood change from one phase to another: What causes neighborhoods to decline? What causes neighborhoods to reorganize, revitalize, and prosper? Dimensions of change are also examined. A focus on slow and fast changing variables and attention to both change and persistence correspond to an interest in types and rates of change. Numerous types of data and analyses will be employed, including hi-resolution, remotely sensed data, long-term Census data, parcel-level cadastral data, key-informant surveys, water and air sampling, and micro-habitat analysis. In addition to these data and analyses, three workshops - one for each research theme - bring together all of the members of the DC-BC ULTRA community. These workshops develop a Community of Practice that coalesces around the idea of just, sustainable cities and provides opportunities for interactions among constituencies and communication about research findings with multiple groups. This project adopts a fully integrated research-education-outreach model that includes researchers, students, and decision-makers. Researchers and managers collaborate in a full research-application cycle: a) identify questions, b) collect new data and share existing data, c) analyze data, d) interpret results, e) apply findings, and f) identify new questions. Students are engaged in relevant content through coursework and continue to work on the project through paid fellowships, internships, and capstone or thesis projects. Students are recruited from classes and across the DC Consortium and universities in the Baltimore region to apply for paid ULTRA research fellowships. ULTRA Fellows work directly with researchers and managers on projects, attend ULTRA workshops, and contribute to manuscripts. The broad array of opportunities in the natural and social sciences and from basic research to applied internships are designed to attract a diverse student group and diverse set of interests.
