Recent discussions of contentious politics have focused on struggles in and over space and place. This article builds upon these concerns by using ethnographic, interview, and documentary data to analyze the spatial politics of street market vendors in Santiago, Chile. Drawing upon Lefebvre’s concepts of perceived, conceived, and lived space as well as ideas drawn from research on space and protest, I show how street market vendors build upon spatial routines, a sense of place, political alliances, and scale jumping in their self-defense strategies at the local, national, and international scales. The findings illustrate Lefebvre’s argument that the advance of abstract space (constructed by dominant economic and political elites) provokes resistance by groups who defend and seek to reconstruct lived space.

An international consensus on the need to reduce the use of chlorofluorocarbons (CFCs) and other ozone-depleting gases such as the halons led to the adoptions of the 1987 Montreal Protocol and Title VI of the 1990 Clean Air Act Amendments, "Protecting Stratospheric Ozone." These agreements included major provisions for reducing and eventually phasing out production and use of CFCs and halons as well as advancing the development of replacement chemicals. Because of the ubiquitous use and benefits of CFCs and halons, an expeditious search for safe replacements to meet the legislative deadlines is of critical importance. Toxicity testing and health risk assessment programs were established to evaluate the health and environmental impact of these replacement chemicals. Development and implementation of these programs as well as the structural-activity relationships significant for the development of the replacement chemicals are described below. A dose-response evaluation for the health risk assessment of the replacement chemical HCFC-123 (2,2-dichloro-1,1,1-trifluoroethane) is also presented to show an innovative use of physiologically based pharmacokinetic (PBPK) modeling. This is based on a parallelogram approach using data on the anesthetic gas halothane, a structural analog to HCFC-123. Halothane and HCFC-123 both form the same metabolite, trifluoroacetic acid (TFA), indicative of the same metabolic oxidative pathway attributed to hepatotoxicity. The parallelogram approach demonstrates the application of template model structures and shows how PBPK modeling, together with judicious experimental design, can be used to improve the accuracy of health risk assessment and to decrease the need for extensive laboratory animal testing.  相似文献

This study aims to explore the prevalence of clinic-based research among accredited marriage and family therapy (MFT) programs and reveal rationales explaining why academic settings may or may not be conducting clinical research. Findings of this project are the result of electronic-mail surveys completed by 26 accredited MFT programs. Approximately one-half of the respondents reported currently conducting clinic-based research. Open-ended responses reveal factors that lead to research success and failure, as well as reasons research was not being conducted at training programs.  相似文献

This article describes the Durham Family Initiative (DFI), an innovative effort to bring together child welfare and juvenile justice systems to reach DFI's goal of reducing the child abuse rate in Durham, North Carolina, by 50% within the next 10 years. DFI will follow principles of a preventive system of care (PSoC), which focuses on nurturing the healthy parent-child relationship. A community collaborative of government agency directors has signed a memorandum of agreement to implement the PSoC principles. The researchers will use multiple methods to evaluate DFI's efficacy.  相似文献

War and social transition in Croatia have increased unemployment and rates of substance abuse. A decrease in prevention programs places adolescents at an increased risk. Data collected from the 2002 Split Youth Behavior Risk Survey (YRBS) showed that adolescents are at risk for alcohol use and related problems. Thus, there is a need to strengthen primary and secondary prevention activities to empower adolescents and counteract negative societal change. A public health partnership between the University of Medicine and Dentistry of New Jersey-School of Public Health (UMDNJ-SPH) and Split, Croatia was formed in 2001. Adolescent alcohol prevention was identified as our focus and Project Northland, a model U.S. program, was selected. A strong network of NGOs and government officials support the project. Qualitative evaluation showed strong parent, teacher, and student satisfaction. Preliminary analysis shows a heightened awareness on the part of students that will likely contribute to the overall success of the program.  相似文献

The Doubles, funded by the National Institute on Drug Abuse, is a seven-episode series of media tools designed to teach third and fourth grade students about the science of drug addiction. The program's curriculum is delivered via a set of videos, interactive CD-ROMs, workbooks, or an Internet site. This article examines the process used to develop The Doubles and argues that its success stems from the careful balancing of the needs of the funding agency, state and national curricular guidelines, and the target audience.  相似文献
