This article examines the "military metropolis," an urban community that depends highly on military expenditures in order to sustain economic vitality. We build on past theories of military Keynesianism and employ insights from urban political economy theory to examine the effects of defense contracts and defense personnel spending on five measures of labor market quality (median household income, income inequality, poverty 125 percent, unemployment, and casualization) in 276 U.S. metropolitan statistical areas in the year 2000. Whereas previous studies of military spending have focused primarily on nations and U.S. states, this study examines metropolitan areas. We test three hypotheses about how federal military outlays might influence urban economies: first, the defense–dependency hypothesis suggests that urban areas rely on defense dollars in varying degrees to sustain their economic stability and vitality. Second, the localized effects hypothesis proposes that defense personnel spending on military bases and civilian personnel will have more immediate effects on urban economies than spending on defense procurement contracts. Third, the gunbelt hypothesis predicts that military spending has affected urban economies unevenly, benefiting metropolitan areas in some regions of the country more than others. The results of this study support all three hypotheses. We offer interpretations of our results and discuss the policy implications for U.S. metropolitan areas.

HIV, hepatitis B & C, drug overdose, and other drug-related health problems still pose significant health risks to injection drug users (IDUs) and their sexual partners, indicating the need for further development of innovative public health interventions. A relatively new intervention implemented in many municipalities throughout the world is the "safer injection site" (SIS). An SIS is a legal facility that allows people to prepare and inject pre-obtained drugs in a hygienic, anxiety-free atmosphere under the supervision of health personnel. This paper examines the responses of a sample of IDUs in New York City to whether they would use an SIS should one be implemented in mid-town Manhattan. The SIS would be part of a comprehensive harm reduction project that already offers needle-exchange, street outreach, testing and counseling, support groups, referral services including drug treatment, and on-site primary medical and dental services. The results of our study indicate that a large majority of the IDUs sampled would utilize an SIS should one be implemented, and that those most likely to use it are IDUs at the highest risk for contracting or spreading blood-borne diseases such as HIV and hepatitis, and for experiencing a drug overdose.

Results are presented of enrolling HIV+ active-injection drug users (IDUs) into a peer-driven intervention (PDI) to improve their adherence to medical care. Using respondent-driven sampling (RDS), which evolved out of the PDI model, the authors recruited and tested 1,097 IDUs, of whom 145 were confirmed to be HIV+. Despite promises of confidentiality, increased social supports, and direct cash rewards for participating, only 78 (54%) of the HIV+ IDUs enrolled in the subsequent adherence study. Correlates of participation as well as interviews with respondents who declined participating are presented. The seemingly negative findings have important implications for future adherence studies. RDS provided a powerful mechanism for recruiting HIV+ IDUs. But selection biases were revealed to favor sicker yet more socially connected respondents, which resulted in more conservative outcomes with regard to social supports and positive health-seeking behaviors. The analysis may help streamline future efforts using the PDI, which harnesses IDUs' abilities to help one another, by underscoring some of the mechanism's limitations.
