Ruth D. Peterson and Lauren J. Krivo are two researchers who used the National Neighborhood Crime Study to observe the racial-spatial dynamics of neighborhood violence. The two examined thirty-six cities in the United States and found that not only do the economic conditions present in these neighborhoods have an effect on the violence that occurs in the area, but also the proximity to more disadvantaged or racially privileged areas can also have an influence on the violence that arises in various black neighborhoods. In this article I review research conducted by Peterson and Krivo on segregated spatial locations, ethnic composition, and neighborhood violent crime. I will begin my article with a discussion of the main purpose of the research. The key points I focused on in this section were the ideas that internal and nearby neighborhood conditions lead to racial and ethnic differences in violence in areas and why this research was important and previous research conducted on this topic (Groveland). I then discuss the theoretical framework of the article and the hypothesis that guided the research. In this section I address the general criminological theory that the researchers used to inform their analysis. (Social disorganization theory) Finally, I conclude the critique of the article with a summary of the study design and the results of the research experiment. In this study, researchers Ruth D. Peterson and Lauren J. Krivo assessed racial disparity within various U.S. cities and determined how these conditions lead to racial and ethnic differences in different areas. They examined the racial spatial dynamics of violence in 36 city neighborhoods across the United States. The importance of this study represents how cultural differences can influence...... half of the paper ......why this research is important. Research in this field will help us learn and understand our communities better. It will allow us to better understand how we can improve our communities and how we can minimize violence regardless of color. I also think the author stayed true to the goals I stated at the beginning of the article. Works Cited1. Peterson, R. D., & Krivo, L. J. (2009).
