Assimilating disadvantaged workers in labor markets has been the focus of national policy initiatives for at least two decades. In recent years, public policies have been formulated which will not only provide incentives for the private sector to employ the disadvantaged, but also afford the private sector a larger responsibility in formulating and implementing targeted employment programs. The Job Training Partnership Act (JTPA) and Target Jobs Tax Credit (TJTC) are two major examples. This paper initially reviews the public and private employment and training efforts between 1962 and 1982. Considerable attention is given to summarizing and evaluating the performance of these efforts, especially in light of recent program initiatives by the Reagan Administration.  相似文献

Efflux times were measured for dilute solutions of short lengths of ten single polyester fibers by micro capillary viscometry using a 50-μl charge. Limiting viscosity numbers (intrinsic viscosities) and molecular weights were calculated for each fiber by a single-point method. Efflux times were measured for three of the fibers after they were subjected to two different laundering procedures and outdoor exposure. The viscometric method was unsuitable for fiber identification but was shown to be highly discriminating for the comparison of fibers of similar commercial origins.  相似文献

We report a case of a small infant apparently dying of the Sudden Infant Death Syndrome (SIDS) with a postmortem blood dicyclomine level of 200 ng/mL. Review of the literature and the comparison with blood dicyclomine values from four rabbits given equivalent doses suggests that a blood dicyclomine value of 200 ng/mL probably is in the therapeutic range for infants. Although safely used for years for infantile colic, recently, the administration of dicyclomine has been related to acute episodes of apnea, seizures, and coma. In the absence of those acute reactions, we feel that a 200-ng/mL blood dicyclomine level in a child dying of apparent SIDS should not prevent categorization of the death as SIDS.  相似文献

A fatal case of chronic intravenous drug abuse involving the injection of a nonpsychoactive veterinary combination of penicillin G and streptomycin is reported. The circumstances surrounding the death indicate that the decedent died as a result of streptomycin induced paralytic neuromuscular blockade.  相似文献

Little attention is given to the violent female adolescent. While there is no argument that males commit most of the violent crimes (both juveniles and adults), violent females may demand the attention of policy-makers and administrators. Historically there has been a lack of program offerings for these offenders. This article examines violent female adolescent offenders referred to the Clark County (Las Vegas, Nevada) Juvenile Court Services in two different years (1985 and 1988). This examination includes a review of programs and alternatives for these offenders and a review of what is currently being done by the juvenile justice system to accommodate this population. Dispositions and programmatic treatment offerings for violent adolescent males and females are compared. Recommendations are offered for the juvenile justice system for consideration.  相似文献
