School choice,racial segregation,and test‐score gaps: Evidence from North Carolina's charter school program*

Using panel data that track individual students from year to year, we examine the effects of charter schools in North Carolina on racial segregation and black‐white test score gaps. We find that North Carolina's system of charter schools has increased the racial isolation of both black and white students, and has widened the achievement gap. Moreover, the relatively large negative effects of charter schools on the achievement of black students is driven by students who transfer into charter schools that are more racially isolated than the schools they have left. Our analysis of charter school choices suggests that asymmetric preferences of black and white charter school students (and their families) for schools of different racial compositions help to explain why there are so few racially balanced charter schools. © 2006 by the Association for Public Policy Analysis and Management.     

Sexual attitudes and behavior of bulimic women: A preliminary investigation

One-hundred and seventeen college-aged women at varying risk for developing bulimia answered a number of questions addressing their attitudes toward and comfort with sexuality as well as their sexual and contraceptive history. Risk for developing bulimia was unrelated to sexual attitudes and weakly related to greater comfort with sexuality. High-risk women reported first engaging in intercourse at earlier ages and were also more likely to engage in risky contraceptive behavior than their lower risk counterparts. Despite their tendency to report a greater number of previous sexual partners, high-risk women currently engaged and expected to continue to engage in sex less frequently than lower risk women. Taken together with previous findings, results suggest that the relationship between risk for bulimia and certain patterns of sexual behavior reflects a general cycle of impulsive and controlling behavior exhibited by high-risk women.

An improved method for post-PCR purification for mtDNA sequence analysis

Mitochondrial DNA (mtDNA) analysis of forensic samples typically is performed when the quantity and quality of DNA are insufficient for nuclear DNA analysis or when maternal relatives may be the only reference source. Many of the steps required in the analytical process are both lengthy and labor intensive. Therefore, improvements in the process that reduce labor without compromising the quality of the data are desirable. The current procedure requires purification of the amplicons by centrifugal filtration after PCR and prior to cycle sequencing. Because this method requires several manipulations to perform, alternate cleanup procedures were investigated. These include the use of 1) Qiagen QlAquick PCR Purification columns, 2) Concert Rapid PCR Purification columns, and 3) ExoSAP-IT reagent. When the yield of purified amplicons, quality of the sequence profile, and ease of assay were evaluated, the use of ExoSAP-IT reagent for post-amplification purification was chosen to replace the filtration method.     

Studying contemporary Europe

The study of contemporary Europe has attracted growing attention in mainstream political science and international relations. Both studies of the European Union and cross-country comparisons of various political phenomena in different European countries are beginning to enrich our understanding of the process and limitations of integration. This growth of interest has also been stimulated by the opening up of central and eastern Europe which has encouraged scholars to address the issues of transformation using the tools of comparative politics. In addition, studies of Europeanisation are now being more systematically related to broader international developments and to the process of globalisation. British scholars, and British-based scholars, are making important contributions to the debates in political science and international relations. This review article traces some of the strands of this development.
