The Pittsburgh Youth Study is a prospective longitudinal survey of three samples of Pittsburgh boys (each containing about 500 boys) initially studied in first, fourth, and seventh grades. The first two data collection waves yielded self-reported delinquency and combined delinquency seriousness scores (the combined scores based on information from boy, mother, and teacher) for the middle sample (up to an average age of 10.7 years) and oldest sample (up to an average age of 13.9 years). These scores were compared with records of petitions to the Allegheny County Juvenile Court for delinquency offenses before and up to six years after the assessments. The area under the ROC curve was used as a measure of validity. Concurrent validity was higher than predictive validity. The combined scale had similar concurrent validity but greater predictive validity than the self-report scale, and the combined scale also identified a greater number of boys as serious delinquents. Concurrent validity for admitting offenses was higher for Caucasians, but concurrent validity for admitting arrests was higher for African-Americans. There were no consistent ethnic differences in predictive validity. There was an increase in predictive validity, for both African-Americans and Caucasians, by combining self-report data with information from other sources. Afrer controlling for delinquency measures, African-Americans were more likely than Caucasians to be petitioned in the future, but not in the past. In this research, ethnic differences in official delinquency were partly attributable to ethnic differences in delinquent behavior and were not attributable to differential ethnic attrition or differential ethnic validity of measures of delinquent behavior. 相似文献

Based on data collected from prosecutors' files on domestic violence cases, the research reported here attempts to isolate variables associated with a decision to issue criminal charges in a case. The analysis reveals that variables reflective of the defendant's current or past choices were most strongly associated with the charging decision. Specifically, the defendant's appearing at the charging conference and his use of drugs or alcohol at the time of the violence were the factors most strongly associated with the decision to issue a criminal charge. Other related factors were also reflective of choices made by the defendant: degree of injury inflicted, the instrument used, the fact of prior offenses, and prior abuse of the particular victim. 相似文献

Is Internet freedom an absolute, universal value like freedom of speech? If there are limits, how and by whom can they be established? Is crying fire or scaling firewalls anymore acceptable in cyberspace than in physical space? What is the impact on the discourse between nations, cultures and individuals? In this section, we gather a collage of comments from various key players from Google to Wikileaks to the US State Department along with comments by one of the most cogent analysts of the Net and the president of Turkey. 相似文献

The recent scandal of the National Security Agency (NSA) “Hoovering” up the metadata on US and foreign citizens from Google, Facebook and Yahoo exposes in the full light of day the central paradox of the new digital age: The Internet enables us to know and learn more than ever before, but enables more to be known and learned about us by both snooping governments and monetizing information corporations alike. In this section, Google's Eric Schmidt and Jared Cohen discuss this paradox. We also reprint an interview from 2009 with Mike McConnell, a former chief of the National Security Agency and the driving force behind Booz, Allen, Hamilton's digital security operation. Edward Snowden, the systems administrator who blew the whistle, was employed by the NSA as a subcontractor from Booz, Allen, Hamilton. 相似文献

Persons arrested for misdemeanor domestic violence are held in custody for widely varying lengths of time. To test the effects of this variance, we randomly assigned short (X?= 2.8 hours), full (X?= 11.1 hours), and no arrests (warning only) to a sample of 1,200 cases with predominantly unemployed suspects concentrated in black ghetto poverty neighborhoods in Milwaukee. Victim interviews and one official measure showed that short arrest had a substantial initial deterrent effect relative to the warning group. Longer term follow-up and before-after analysis, however, found neither arrest group reflected any deterrence. On the most comprehensive official measure, short arrest consistently showed significantly higher long-term recidivism than no arrest. Its deterrent effect ended at 30 days, but its criminogenic effect was significant after one year. We conclude that short-custody arrests for domestic violence in poverty ghetto areas may pose a dilemma between short- and long-term crime control, but longer custody arrests have no clear long-term effect in either direction. 相似文献
