Does Hazardous Waste Matter? Evidence from the Housing Market and the Superfund Program

This paper uses the housing market to develop estimates of the local welfare impacts of Superfund sponsored clean-ups of hazardous waste sites.We show that if consumers value the clean-ups, then the hedonic model predicts that they will lead to increases in local housing prices and new home construction, as well as the migration of individuals that place a high value on environmental quality to the areas near the improved sites. We compare housing market outcomes in the areas surrounding the first 400 hazardous waste sites chosen for Superfund clean-ups to the areas surrounding the 290 sites that narrowly missed qualifying for these clean-ups.We find that Superfund clean-ups are associated with economically small and statistically indistinguishable from zero local changes in residential property values, property rental rates, housing supply, total population, and the types of individuals living near the sitesThese findings are robust to a series of specification checks, including the application of a quasi-experimental regression discontinuity design based on knowledge of the selection rule. Overall, the preferred estimates suggest that the local benefits of Superfund clean-ups are small and appear to be substantially lower than the $43 million mean cost of Superfund clean-ups.

Does Hazardous Waste Matter? Evidence from the Housing Market and the Superfund Program

Approximately $30 billion (2000$) has been spent on Superfund clean-ups of hazardous waste sites, and remediation efforts are incomplete at roughly half of the 1,500 Superfund sites. This study estimates the effect of Superfund clean-ups on local housing price appreciation. We compare housing price growth in the areas surrounding the first 400 hazardous waste sites to be cleaned up through the Superfund program to the areas surrounding the 290 sites that narrowly missed qualifying for these clean-ups. We cannot reject that the clean-ups had no effect on local housing price growth, nearly two decades after these sites became eligible for them. This finding is robust to a series of specification checks, including the application of a quasi-experimental regression discontinuity design based on knowledge of the selection rule. Overall, the preferred estimates suggest that the benefits of Superfund clean-ups as measured through the housing market are substantially lower than the $43 million mean cost of Superfund clean-ups.Valuation of environmental goods, Hazardous waste sites, Environmental regulation, Regression discontinuity, Superfound, Externalities

JSTOR Plant Science

JSTOR Plant Science is an online environment that brings together content, tools, and people interested in plant science. It provides access to foundational content vital to plant science – plant type specimens, taxonomic structures, scientific literature, and related materials, making them widely accessible to the plant science community as well as to researchers in other fields and to the public. It also provides an easy to use interface with powerful functionality that supports research and teaching, including the ability to measure and record plant specimens, share observations and objects with colleagues and classmates, and investigate global plant biodiversity

Listening walks: a method of multiplicity

A listening walk is a mode of walking in which listening to the sounds of spaces is the focus. In this chapter, we look at the potential of listening walks to act as a research method and pedagogic tool. We emphasise its flexibility and adaptability for different purposes and research topics. To make this argument, we consider a listening walk led by one of the authors in Edinburgh, Scotland. We demonstrate that, while listening walks have been posited as a means of producing research data about perceived soundscape quality, they also provide us with an endlessly repeatable and adaptable method that can address a much broader range of research questions, and can be embedded within a variety of teaching settings

Intermolecular hydrogen bonding of the two independent molecules of N-3,5-dinitrobenzoyl-L-leucine

The title compound, C₁₃H₁₅N₃O₇, crystallizes as two independent molecules which differ in their conformation. Intermolecular hydrogen bonding between the amide and carboxylic acid groups as N-H...O=C interactions results in the formation of one-dimensional chains with N...O distances of 2.967 (6) and 3.019 (6) Å. Neighbouring chains are linked by C=O...H-O interactions to form a two-dimensional network, with O...O distances of 2.675 (6) and 2.778 (6) Å

The MEKK1 PHD ubiquitinates TAB1 to activate MAPKs in response to cytokines.

Unlike the other MAP3Ks, MEKK1 (encoded by Map3k1) contains a PHD motif. To understand the role of this motif, we have created a knockin mutant of mouse Map3k1 (Map3k1(m) (PHD)) with an inactive PHD motif. Map3k1(m) (PHD) ES cells demonstrate that the MEKK1 PHD controls p38 and JNK activation during TGF-β, EGF and microtubule disruption signalling, but does not affect MAPK responses to hyperosmotic stress. Protein microarray profiling identified the adaptor TAB1 as a PHD substrate, and TGF-β- or EGF-stimulated Map3k1(m) (PHD) ES cells exhibit defective non-canonical ubiquitination of MEKK1 and TAB1. The MEKK1 PHD binds and mediates the transfer of Lys63-linked poly-Ub, using the conjugating enzyme UBE2N, onto TAB1 to regulate TAK1 and MAPK activation by TGF-β and EGF. Both the MEKK1 PHD and TAB1 are critical for ES-cell differentiation and tumourigenesis. Map3k1(m) (PHD) (/+) mice exhibit aberrant cardiac tissue, B-cell development, testis and T-cell signalling
