This article reports the results of the national evaluation of the Food Stamp Employment and Training (E&T) Program, based on an experimental study involving over 13,000 program participants in 53 separate local food stamp agencies. The story told by these findings begins with the types of individuals who participated in the E&T Program in FY 1988. Nearly 70 percent did not have children (removing this barrier to finding employment), and about half were single, highly mobile adults living alone. Most received no public assistance other than food stamps. For the most part, then, these were individuals who needed to work—food stamp benefits are not intended to meet total subsistence needs. It would, therefore, be expected that most of the E&T participants would be looking for work (whether or not they were successful) in the absence of E&T requirements. Next, it is apparent that large numbers of E&T participants did not engage in employment or training services in FY 1988. As currently structured, beyond imposing the obligation to meet the requirements of E&T, the program failed to provide any actual services to about half of those deemed eligible to participate. For the most part, the services received by E&T participants consisted primarily of referral to individual job search. In the absence of E&T, many of the individuals currently targeted by the program were able to obtain similar referrals on their own. Consequently, it is not surprising, that E&T was found to have no effect on participants' employment and earnings, and only a relatively small effect on average food stamp benefits.  相似文献

Bystanders killed by bullets not specifically intended for them have long been a very small part of the homicide problem. But the frequency of press accounts of such killings and woundings has apparently increased nationally in recent years. To test this impression, we compiled all shootings of bystanders hit at random and reported in the published indexes of theNew York Times, theLos Angeles Times, and theWashington Post for 1977–1988, as well as a key word computer search of stories in theBoston Globe. We found a rapid increase in both bystander woundings and killings since 1985 in all four cities. The base rate was quite low, and total bystander deaths appear to comprise less than 1% of all homicides in these cities. Nonetheless, the numbers were large enough to show that most bystanders reported shot in New York and Los Angeles are victims of random shootings into crowds, rather than single stray bullets striking a lone individual mushroom. The reverse was true in Boston and Washington, with the effect of much lower rates of bystanders reported shot in those cities.  相似文献
