Abandoned housing: Exploring lessons from baltimore 总被引:1,自引:0,他引:1
James R. Cohen 《Housing Policy Debate》2013,23(3):415-448
Abstract Population loss and economic decline have resulted in thousands of abandoned homes in major U.S. cities. Although abandoned homes are symptomatic of other problems, they also contribute to neighborhood decline and frustrate revitalization. This article provides an overview of the national scope of abandoned housing and profiles Baltimore's strategy for addressing this problem. Challenges in Baltimore's revitalization planning include the necessity of and financial requirements for a comprehensive approach and the difficulty of reaching consensus. Widespread property “flipping” hampers prevention. Efforts to acquire and demolish units are constrained by difficulties in tracking ownership, felons’ ownership of derelict units, and a shortage of staffing to process takings. Challenges in rehabilitating and marketing row houses include the need for subsidies to make units affordable to the most likely buyers, the omnipresence of lead paint, and the lack of foreign immigration. The article proposes a more strategic approach to the city's revitalization planning. 相似文献

The primary aims of this article are (a) to examine the importance of cultural norms and what part they play in requiring us to tolerate others out of respect, and (b) to formulate some guidelines designed to prescribe boundaries to liberty and tolerance conducive to safeguard the rights of individuals and, in turn, democracy. I argue that a liberal democracy can interfere in the business of its sub‐cultures when some cultural norms subvert the basic principles upon which a liberal society is founded. I proceed by making a further radical claim that democracy may prevent cultural groups from entering society if their conceptions of the good essentially conflict with its norms. My basic argument is that considerations of context and intentions must be taken into account, and that they may require the introduction of constraints. I conclude by considering the question whether or not the intolerant group has any right to complain, arguing that it does not.1 相似文献

Dental stone is used as the major material for recovering three-dimensional shoeprints and tire tracks from crime scenes. The procedure for using dental stone sparsely changed over the years. There are two common methods for mixing dental stone: (i) a premeasured amount of dental stone is put in a zip-lock bag to which water is added, and (ii) the water and dental stone are mixed in a bucket. We suggest a novel rapid and efficient method of mixing dental stone and water in a bottle. These methods were compared at equal conditions. The parameters measured were the number of air bubbles, the strength of the cast, the ease of use, and the sharpness and quality of the accidental characteristics present in the cast. The proposed bottle method has the advantages of both the bucket and the zip-lock methods hence it combines strength, sharpness, high quality, and ease of use. 相似文献

Abstract: Genetic information in forensic studies is largely limited to CODIS data and the ability to match samples and assign them to an individual. However, there are circumstances, in which a given DNA sample does not match anyone in the CODIS database, and no other information about the donor is available. In this study, we determined 75 SNPs in 24 genes (previously implicated in human or animal pigmentation studies) for the analysis of single‐ and multi‐locus associations with hair, skin, and eye color in 789 individuals of various ethnic backgrounds. Using multiple linear regression modeling, five SNPs in five genes were found to account for large proportions of pigmentation variation in hair, skin, and eyes in our across‐population analyses. Thus, these models may be of predictive value to determine an individual’s pigmentation type from a forensic sample, independent of ethnic origin. 相似文献

As important as the study of history for military strategists is the acquisition of the historical mind—that is, a way of thinking that uses history as a mode of inquiry. From practical cases to inspiration, history can help with U.S. military decision-making. The historical mind will detect differences as much as similarities between cases, avoiding false analogies, and look for the key questions to be asking. It will look for continuity but also for more important discontinuities; it will look for linkages between data points, but not be too quick to attribute causation. It is a well-traveled mind that appreciates the variability of people and places, conditions and problems; it avoids over-reliance on “lessons learned.” For that reason, the historical education of civilian and military strategists is more, not less, important in an age of rapid change. 相似文献
