Revitalizing inner‐city neighborhoods: New York city's Ten‐Year Plan

Abstract

This article examines the impact of New York City's Ten‐Year Plan on the sale prices of homes in surrounding neighborhoods. Beginning in the mid‐1980s, New York City invested $5.1 billion in constructing or rehabilitating over 180,000 units of housing in many of the city's most distressed neighborhoods. One of the main purposes was to spur neighborhood revitalization.

In this article, we describe the origins of the Ten‐Year Plan, as well as the various programs the city used to implement it, and estimate whether housing built or rehabilitated under the Ten‐Year Plan affected the prices of nearby homes. The prices of homes within 500 feet of Ten‐Year Plan units rose relative to those located beyond 500 feet, but still within the same census tract. These findings are consistent with the proposition that well‐planned project‐based housing programs can generate positive spillover effects and contribute to efforts to revitalize inner‐city neighborhoods.     

The contributions of historic preservation to housing and economic development

Abstract

Historic preservation contributes greatly to housing and economic development. Historic preservation has produced almost 250,000 housing units through use of the federal historic rehabilitation tax credit. Additionally, heritage tourism is a multibillion‐dollar industry, and preservation projects help further community revitalization.

Historic preservation also has a downside. Preservation's growing popularity may dilute its imperative and market prowess, and some argue it is used to thwart new development. Preservation requirements may impede affordable housing production and displace area residents. These undesirable consequences are not givens, however. Preservationists are working to become more flexible, and we suggest ways to practice historic preservation while mitigating some of its negative consequences—for example, tax credit changes, more flexible building codes, and a “tiered” system of designating historic properties at varying levels of significance.     

The redevelopment of distressed public housing: Early results from HOPE VI projects in Atlanta,Chicago, and San Antonio

Abstract

The redevelopment of distressed public housing under the Urban Revitalization Demonstration Program, or HOPE VI, has laudable social, physical, community, and economic goals. Three public housing projects in Atlanta, Chicago, and San Antonio demonstrate the complexity and trade‐offs of trying to lessen the concentration of low‐income households, leverage private resources, limit project costs, help residents achieve economic self‐sufficiency, design projects that blend into the community, and ensure meaningful resident participation in project planning.

Although worthwhile and ambitious, HOPE VI cannot achieve all these goals. More of them can be achieved by developing strategies related to the strength of the local real estate market. To that end, the U.S. Department of Housing and Urban Development and public housing authorities must use the market‐based tools in the Quality Housing and Work Responsibility Act of 1998. Standards for improved physical design and resident participation and further research on critical supportive services for residents are also needed.     

The Mujahideen in Bosnia: the foreign fighter as cosmopolitan citizen and/or terrorist

This article explores the idea of the Mujahideen in Bosnia as ‘cosmopolitan citizens’. During the Balkan War in the early 1990s, these foreign fighters flocked to Bosnia in order to take up arms alongside those whom they understood to be their besieged Muslim brethren. Although this act of transborder mobilization can be framed as an act of cosmopolitan citizenship, the subsequent ‘problem’ of the Mujahideen in a post-9/11 context destabilized their original cosmopolitan act through a re-enactment of borders and the revocation of their (literal) citizenship. Within the larger post-9/11 narrative, where the Mujahideen must necessarily be understood as terrorists/potential terrorists, they are an interesting point of study in an examination of what can be seen as the sinister side of transnational citizenship, and they expose what Appadurai (A. Appadurai, 2006. Fear of small numbers: an essay on the geography of anger. Durham: Duke University Press.) calls our ‘fear of small numbers’. Particularly compelling is that the post-9/11 Mujahid is an unsympathetic figure, and is always already a questionable candidate for ‘citizenship’ as it is commonly understood. Furthermore, his (sic) original ‘cosmopolitan’ act suggests that, although the ‘cosmopolitan ideal’ is the achievement of a citizenship that transcends or escapes borders, the cosmopolitical must nevertheless be assigned value in order to be ethically intelligible.     

Regionalist governance and transnational collective action in Latin America

Abstract

New forms of regionalism are now a central element in global governance. It is sometimes suggested that new regionalism represents an opportunity for transnational civil society activism. I explore this argument through a comparison of processes of collective action in two emerging frames of regionalism governance in the Americas, the FTAA/Summit of the Americas and Mercosur. I show that, while civil society activism has regionalized to some extent in relation to both hemispheric regionalism and sub-regionalism, this process is far more marked in the former. I suggest, further, that the influence of civil society actors in regionalist governance in the Americas is extremely limited. This is due to persistent institutional barriers to inclusion, the practical obstacles for many groups of scaling up to the regional/transnational level and the particular difficulties associated with accessing trade-based negotiations.     

GC/MS衍生化测定精浆中游离支链氨基酸和果糖

目的 建立人精浆中支链氨基酸和果糖的气相质谱衍生化分析方法.方法 精液样本液化离心后,按精子活率的临床标准分为正常组和非正常组,经TMS微波衍生化,GC/MS分析两组支链氨基酸、果糖衍生物含量差异.结果 正常组与非正常组的缬氨酸,亮氨酸,异亮氨酸在相对含量上均有一定差异.正常组3种氨基酸相对含量高于非正常组.果糖分析观察到同样的特征,正常组相对含量高于非正常组.结论 精子活率低的精浆样本仍可检出支链氨基酸和果糖,其差异有助于无精子、少精子精斑的法医学鉴别.
