SUPERFUND: AN ANALYSIS OF IMPLEMENTATION FAILURE (CERCLA, HEALTH LAW POLICY)

In December, 1980, following increasing congressional and constituent-interest in problems associated with hazardous waste, the Comprehensive Environmental Recovery, Compensation and Liability Act (CERCLA) was passed. During its development, the legislative initiative was seriously compromised which resulted in a less exhaustive approach than was formerly sought. Still, CERCLA (Superfund) which established, among other things, authority to clean up abandoned waste dumps and to respond to emergencies caused by releases of hazardous substances was welcomed by many as an important initial law critical to the cleanup of the nation's hazardous waste. Expectations raised by passage of this bill were tragically unmet. By the end of four years, only six sites had been declared by the EPA as cleaned. Seemingly, even those determinations were liberal; of the six sites, two were identified subsequently as requiring further cleanup.^ This analysis is focused upon the implementation failure of the Superfund. In light of that focus, discussion encompasses development of linkages between flaws in the legislative language and foreclosure of chances for implementation success. Specification of such linkages is achieved through examination of the legislative initiative, identification of its flaws and characterization of attendant deficits in implementation ability. Subsequent analysis is addressed to how such legislative frailities might have been avoided and to attendant regulatory weaknesses which have contributed to implementation failure. Each of these analyses are accomplished through application of an expanded approach to the backward mapping analytic technique as presented by Elmore. Results and recommendations follow.^ Consideration is devoted to a variety of regulatory issues as well as to those pertinent to legislative and implementation analysis. Problems in assessing legal liability associated with hazardous waste management are presented, as is a detailed review of the legislative development of Superfund, and its initial implementation by Gorsuch's EPA. ^

Polymorphisms, linkage and mapping of four enzyme loci in the fish genus Xiphophorus (Poeciliidae).

Electrophoretic variants at four additional enzyme loci--two esterases (Est-2, Est-3), retinal lactate dehydrogenase (LDH-1) and mannose phosphate isomerase (MPI)--among three species and four subspecies of fish of the genus Xiphophorus were observed. Electrophoretic patterns in F1 hybrid heterozygotes confirmed the monomeric structures of MPI and the esterase and the tetrametric structure of LDH in these fishes. Variant alleles of all four loci displayed normal Mendelian segregation in backcross and F2 hybrids. Recombination data from backcross hybrids mapped with Haldane's mapping function indicate the four loci to be linked as Est-2--0.43--Est3--0.26--LDH-1--0.19--MPI. Significant interference was detected and apparently concentrated in the Est-3 to MPI region. No significant sex-specific differences in recombination were observed. This group (designated linkage group II) was shown to assort independently from the three loci of linkage group I (adenosine deaminase, glucose-6-phosphate dehydrogenase, and 6-phosphogluconate dehydrogenase) and from glyceraldehyde-3-phosphate dehydrogenase and two isocitrate dehydrogenase loci. Evidence for conservation of the linkage group, at least in part, in other vertebrate species is presented.

Predicting childhood sexual or physical abuse: a logistic regression geo-mapping approach to prevention.

This study investigates the degree to which gender, ethnicity, relationship to perpetrator, and geomapped socio-economic factors significantly predict the incidence of childhood sexual abuse, physical abuse and non- abuse. These variables are then linked to geographic identifiers using geographic information system (GIS) technology to develop a geo-mapping framework for child sexual and physical abuse prevention.
