Violence Against Women: Reflecting on 25 Years of the Violence Against Women Act and Directions for the Future.

The year 2019 marked the 25th anniversary of the passage of the landmark legislation, the 1994 Violence Against Women Act (VAWA). As we reflect on the Act, it is important to examine how the VAWA influenced the response to violence against women. This guest editors' introduction provides a preview of five articles devoted to a special issue of Violence Against Women. The articles highlight key aspects of VAWA. With H.R. 15851 awaiting consideration by the Senate, we suggest that perhaps now is an appropriate time to assess the Act's impact.

The 1994 Violence Against Women Act: A Historic Response to Gender Violence.

The Violence Against Women Act (VAWA) is frequently questioned about its success, especially during times of its reauthorization. While federal, state, local, and private organizations have funded a significant amount of research through VAWA since its inception, questions remain as to whether the field has the evidence to make a concrete judgment about its success. The purpose of this article is twofold. First, we review the Act and its subsequent reauthorizations. Second, the article addresses issues related to VAWA's success. We consider whether it is possible to answer Moore Parmley's question posed in 2004, p. 1,428: " . . . on the anniversary of the VAWA, will we be able to say with any confidence that the Act helped to prevent violence against women?"

Rate and extent of aqueous perchlorate removal by iron surfaces.

The rate and extent of perchlorate reduction on several types of iron metal was studied in batch and column reactors. Mass balances performed on the batch experiments indicate that perchlorate is initially sorbed to the iron surface, followed by a reduction to chloride. Perchlorate removal was proportional to the iron dosage in the batch reactors, with up to 66% removal in 336 h in the highest dosage system (1.25 g mL(-1)). Surface-normalized reaction rates among three commercial sources of iron filings were similar for acid-washed samples. The most significant perchlorate removal occurred in solutions with slightly acidic or near-neutral initial pH values. Surface mediation of the reaction is supported by the absence of reduction in batch experiments with soluble Fe2+ and also by the similarity in specific reaction rate constants (kSA) determined for three different iron types. Elevated soluble chloride concentrations significantly inhibited perchlorate reduction, and lower removal rates were observed for iron samples with higher amounts of background chloride contamination. Perchlorate reduction was not observed on electrolytic sources of iron or on a mixed-phase oxide (Fe3O4), suggesting that the reactive iron phase is neither pure zerovalent iron nor the mixed oxide alone. A mixed valence iron hydr(oxide) coating or a sorbed Fe2+ surface complex represent the most likely sites for the reaction. The observed reaction rates are too slow for immediate use in remediation system design, but the findings may provide a basis for future development of cost-effective abiotic perchlorate removal techniques.
