Despite the general agreement that US schools have become increasingly punitive since the 1980s, researchers are uncertain about what types of schools use tough-on-crime measures. Some assert that punitive control is concentrated in poor, predominantly ethnic minority schools. Governing-through-crime scholars argue that US schools with mostly middle-class and white students are also punitive, but in less harsh ways using soft surveillance techniques. Relying on data from large, stratified samples of middle and secondary US public schools, we found that high rates of ethnic minority enrollment predicted heavy reliance on law enforcement and security personnel. As rates of student poverty increased, use of soft surveillance techniques as well as reporting students to the police significantly increased. Implications for governing-through-crime, racial control, and reproduction of inequalities theories are discussed. 相似文献

A method is described for obtaining nondistorted, reproducible phosphoglucomutase-1 subtyping patterns from semen stains and bloodstains. Isoelectric focusing of phosphoglucomutase-1 was accomplished in 80 min in a 0.2-mm-thick polyacrylamide gel with an interelectrode wick distance of 8.0 cm. The gel contained 1.2% (w/v) N-(2-hydroxyethyl) piperazine-N-3-propanesulfonic acid (EPPS) and pH 5 to 7 ampholytes (4% w/v). When maintained at room temperature, laboratory-prepared bloodstains and semen stains could be typed for phosphoglucomutase-1 up to four months and three weeks, respectively. An evaluation of phosphoglucomutase-1 typing by isoelectric focusing and the Group I system was performed on casework samples submitted to the FBI Laboratory. In addition to the increased discriminating probability of phosphoglucomutase-1 when subtyped, isoelectric focusing yielded an increase in positive calls on questioned bloodstains (65.6 versus 36.2%) and dried seminal stains (16.4 versus 13.1%) compared with the Group I system. 相似文献

As the twenty-first century begins, a high level of participation in premarital sexual intercourse by college women is well-documented. But, in the research exploring risk-reduction sexual behaviors, the relationship of cognitive abilities to responsible sexual behavior has been under-researched. Anonymous questionnaires were administered to 626 never-married, heterosexual women at a midwestern university to examine personal goal-setting, a cognitive variable postulated to be related to risk-reduction sexual behavior. Women who frequently set goals were more religious, optimistic about life, conservative in sexual attitudes, comfortable with their sexuality, and more psychologically sexually satisfied. Those who less often set goals were more likely to drink alcohol prior to sexual intercourse, become more intoxicated, and less likely to ask if new sex partners had STI(s). The cognitive variable, goal-setting, did differentiate college women who made responsible sexual decisions from those who engaged in risk-taking sexual behaviors.Professor Emerita of Family and Consumer Science, Texas State University-San Marcos.

Donor agencies and foundations use grants to stimulate entrepreneurial growth in developing countries. However, some practitioners have asked whether these grants tend to flow to expatriate entrepreneurs with ties to developed countries (where most grants originate), rather than to local entrepreneurs. This article tackles this question using a data set of 3,434 nascent ventures from 92 developing countries. The authors find that ventures with ties to a developed country are significantly more likely to raise grant financing and in more substantial amounts. Ventures with a founder born in a developed country are the most likely to receive grants, with a weaker effect when considering prior work experience in a developed country. This “expat gap” cannot be explained by differences in education level, prior experience, or ties to other developing countries. Donors seeking to support local entrepreneurs in developing countries should consider ways to make their recruitment and selection processes more equitable. 相似文献

Changes in family formations in western industrialized countriessince the 1960s have not been reflected in cross-national researchin the area of child maintenance. This article outlines childsupport regimes in 14 countries, considering the locus of formaldecision making, the determination of child maintenance obligations– highlighted by way of national informant responses totwo fictitious vignette scenarios – and the enforcementand penalty provisions used in the event of non-compliance.The article concludes that while some broad trends can be identifiedacross countries, there is diversity in how countries respondto family change. 相似文献
