Are management‐based regulations effective? Evidence from state pollution prevention programs

This paper evaluates a recent innovation in regulating risk called management‐based regulation. Traditionally, risk regulation has either specified a particular means of achieving a risk‐reduction goal or specified the goal and left the means of achieving that goal up to the regulated entity. In contrast, management‐based regulation neither explicitly imposes the means, nor the ends. Rather, what is required is that each regulated entity review its production processes and develop a set of goals and procedures that will reduce risk. I evaluate the effectiveness of management‐based regulation by taking advantage of policy variation that occurred when 14 states adopted such regulations for toxic chemical control in the 1990s. Using panel data for just over 31,000 manufacturing plants in the United States, I investigate whether facilities subject to management‐based regulations had larger changes in total quantities of toxic chemical releases, engaged in more pollution prevention activities, or reported fewer toxic chemicals to the Toxics Release Inventory (TRI). The results indicate that management‐based regulation has had a measurable positive effect on the environmental performance of manufacturing plants. In particular, plants subject to management‐based regulation experienced larger decreases in total pounds of toxic chemicals released and were more likely to engage in source reduction activities. © 2007 by the Association for Public Policy Analysis and Management     

Patterns of Intimate Partner Violence in Mothers At-Risk for Child Maltreatment

Using three interviews spanning 3 years, we identified intimate partner violence (IPV) classes and determined how class membership changed over time amongst a sample of 217 mothers at-risk for child maltreatment that were enrolled in an early childhood home visitation evaluation study. Data on perpetration/victimization, IPV type (verbal, physical, and sexual abuse and injury) and severity were used to conduct latent class analyses at each time point. Latent transition analyses established the proportion of mothers who changed classes over time. A three-class solution (minimal, moderate, and high IPV) was indicated at each time point. All classes included mutual IPV. Partners used minor verbal abuse in the minimal class, minor and severe verbal abuse and minor physical abuse in the moderate class, and all IPV categories in the high class. At each transition, 40 % or more women moved from minimal to moderate or high IPV. This movement emphasizes the need to screen women frequently and develop interventions recognizing the dynamic nature of IPV.     

Municipal Rebate Programs for Environmental Retrofits: An Evaluation of Additionality and Cost‐Effectiveness

When policies incentivize voluntary activities that also take place in the absence of the incentive, it is critical to identify the additionality of the policy—that is, the degree to which the policy results in actions that would not have occurred otherwise. Rebate programs have become a common conservation policy tool for local municipalities seeking to retrofit residential properties with efficient appliances. This research evaluates whether such rebates can be cost‐effective means for water utilities to promote water conservation. A unique database is developed that combines water‐use data over a three‐year period for all households that participated in a utility's high‐efficiency toilet (HET) rebate program, water‐use data for a matched sample of neighbors who did not receive a rebate, and a survey of rebate participants. Difference‐in‐differences models indicate that installation of an HET reduces household water consumption by approximately 7 percent. While installation of an HET appears to be an effective means for achieving household reductions in water consumption, our results also suggest that the rebate program is a much less effective means for achieving household reductions in water consumption. Specifically, the rebate program is found to provide limited additional water savings beyond what would have occurred naturally and is responsible for only 37 percent of the total water reduction attributable to the installation of HETs over the study period. © 2013 by the Association for Public Policy Analysis and Management.     

The Evolving Construct of Posttraumatic Stress Disorder (PTSD): DSM-5 Criteria Changes and Legal Implications

In the DSM-5, the diagnosis of posttraumatic stress disorder (PTSD) has undergone multiple, albeit minor, changes. These changes include shifting PTSD placement from within the anxiety disorders into a new category of traumatic and stressor-related disorders, alterations in the definition of a traumatic event, shifting of the symptom cluster structure from three to four clusters, the addition of new symptoms including persistent negative beliefs and expectations about oneself or the world, persistent distorted blame of self or others, persistent negative trauma-related emotions, and risky or reckless behaviors, and the addition of a dissociative specifier. The evidence or lack thereof behind each of these changes is briefly reviewed. These changes, although not likely to change overall prevalence, have the potential to increase the heterogeneity of individuals receiving a PTSD diagnosis both by altering what qualifies as a traumatic event and by adding symptoms commonly occurring in other disorders such as depression, borderline personality disorder, and dissociative disorders. Legal implications of these changes include continued confusion regarding what constitutes a traumatic stressor, difficulties with differential diagnosis, increased ease in malingering, and improper linking of symptoms to causes of behavior. These PTSD changes are discussed within the broader context of DSM reliability and validity concerns.     

Environmental survey for four pathogenic bacteria and closely related species using phylogenetic and functional genes

Bacterial species with high DNA sequence similarity to pathogens could affect the specificity of assays designed to detect biological threat agents in environmental samples. The natural presence of four pathogenic bacteria, Bacillus anthracis, Clostridium perfringens, Francisella tularensis, and Yersinia pestis and their closely related species, was determined for a large collection of soil and aerosol samples. Polymerase chain reaction (PCR) and gene sequencing were used using group-specific 16S rRNA primers to identify pathogens and related species, and pathogen-specific virulence genes. Close relatives of B. anthracis (B. cereus group species) were detected in 37% of the soils and 25% of the aerosol samples. The B. anthracis protective antigen (pag) gene or a close homolog was detected in 16 of these samples. For the other three pathogen groups, the frequency of detection was much lower, and none of the samples were positive with both the phylogenetic and virulence gene primer sets.     

Developmental validation of a single-tube amplification of the 13 CODIS STR loci, D2S1338, D19S433, and amelogenin: the AmpFlSTR Identifiler PCR Amplification Kit

Analysis of length polymorphism at short tandem repeat (STR) loci utilizing the polymerase chain reaction (PCR) process has proven to be an ideal assay for human identification purposes. The short length of STR loci coupled with the amplification of target sequence through PCR allows for a robust, sensitive, and specific assay for highly polymorphic markers. A multiplex containing fifteen STR loci plus the gender-determining locus Amelogenin was developed to provide a single amplification/detection of all CODIS (Combined DNA Index System) STR loci (CSF1PO, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, FGA, TH01, TPOX, and vWA) as well as two internationally-accepted STRs (D2S1338 and D19S433). By incorporating five-dye fragment analysis technology and non-nucleotide linkers, previously optimized AmpFlSTR kit primer sequences have been maintained. This kit has been developed in accordance with the standards of the forensic community as defined by the DNA Advisory Board. Validation studies were performed to include developmental validation, and the results support the use of the AmpFlSTR Identifiler PCR Amplification Kit for human identity and parentage testing.
