This study examines the effectiveness of the Repeat Offender Project (ROP), a specialized police unit in Washington, D.C. It documents how the ROP unit operated, what it cost, and how well it achieved its goal of “selecting, apprehending, and contributing to” the conviction of persons believed to be committing jive or more Part I offenses per week. A controlled experiment showed that the ROP substantially increased the likelihood of arrest for the persons it targeted. Quasi-experimental data indicated that ROP arrestees had longer and more serious histories of prior arrests than a comparison sample of arrestees of officers in other police units. The former arrestees were also more likely to be prosecuted and convicted on felony charges and more likely to be incarcerated. ROP officers’arrest productivity was cut in half; but this cost appears to have been offset by the greater seriousness of the current and prior offenses of its arrestees. The study concludes that the creation of selective apprehension units provides a promising new strategy for major urban police departments.  相似文献

Inconsistent findings on the relationship between poverty and violent crime have led some authors to question the presence of a structural relationship. There is reason, however, to believe that many of the existing estimates are biased because measures of poverty contain errors which are confounded with disturbances in the estimated models. In this paper we specify and estimate a model which accommodates the measurement error and provides an instrumental variable estimate of the effects of poverty on homicide rates in the 49 largest cities in the U.S. Compared to similar OLS estimates, the instrumental variable estimates are much larger and fit a model in which poverty increases the homicide rate. The results are similar when homicides are divided into four types: family homicides, other primary homicides, robbery homicides, and other-felony homicides  相似文献

A major programme of research on cognition has been built around the idea that human beings are frequently intuitive thinkers and that human intuition is imperfect. The modern marketing of politics and the time‐poor position of many citizens suggests that ‘fast’, intuitive, thinking in many contemporary democracies is ubiquitous. This article explores the consequences that such fast thinking might have for the democratic practice of contemporary politics. Using focus groups with a range of demographic profiles, fast thinking about how politics works is stimulated and followed by a more reflective and collectively deliberative form of slow thinking among the same participants. A strong trajectory emerges consistently in all groups in that in fast thinking mode participants are noticeably more negative and dismissive about the workings of politics than when in slow thinking mode. A fast thinking focus among citizens may be good enough to underwrite mainstream political exchange, but at the cost of supporting a general negativity about politics and the way it works. Yet breaking the cycle of fast thinking – as advocated by deliberation theorists – might not be straightforward because of the grip of fast thinking. The fast/slow thinking distinction, if carefully used, offers valuable new insight into political science.  相似文献

Kosovo is a proxy war with the Holocaust. As such, this war and its outcome will do much to define the West in the next century That it is a war in Europe, for Europe, sets it apart from all the other tragedies from Rwanda to Kashmir. Our collage of comment on this subject ranges from the secretary general of NATO to the leader of the Kosovars in Albania.  相似文献

Under the sponsorship of the judiciary, the Santa Clara County, California Juvenile Court, in partnership with the Juvenile Mental Health Department and a technical assistance agency (SOLOMON), has pioneered a Juvenile Mental Health Court for seriously mentally ill children who have become involved in the criminal justice system. The judiciary, probation department, district attorney, public defender, county counsel, and service providers have collectively embarked upon the implementation of a modern approach to mental health diagnosis, triage, and treatment services for youth and families who come in contact with the justice system as a result of the combination of serious mental illness and juvenile delinquency. This article presents the court's rationale and protocols.  相似文献

Most countries struggle to implement CO2 reducing policies. Implementation is politically difficult since it typically forces politicians to trade-off different concerns. The literature on how parties and members of parliament (MPs) handle these trade-offs is sparse. We use structural topic models to study how MPs in an oil dependent environment responded to a shock in the oil price that created spatially concentrated costs of climate policies. We leverage the rapid oil price drop between parliamentary sessions and MPs’ constituency adherence in a difference-in-differences framework to identify if MPs respond differently to variation in the salience of trade-offs. We find that MPs facing high political costs of climate policies tried to avoid environmental topics, while less affected MPs talked more about investments in green energy when the oil price declined. Our results suggest that the oil price bust created a ‘window of opportunity’ for advocates of the ‘ green shift’.  相似文献
