Soil Chemical Response to Experimental Acidification Treatments
One of the conclusions reached during the Congressionally mandated National Acid Precipitation Program (NAPAP) was that, compared to ozone and other stress factors, the direct effects of acidic deposition on forest health and productivity were likely to be relatively minor. However, the report also concluded “the possibility of long-term (several decades) adverse effects on some soils appears realistic” (Barnard et al. 1990). Possible mechanisms for these long-term effects include: (1) accelerated leaching of base cations from soils and foliage, (2) increased mobilization of aluminum (Al) and other metals such as manganese (Mn), (3) inhibition of soil biological processes, including organic matter decomposition, and (4) increased bioavailability of nitrogen (N)

Sedimentation in Quincy Bay and Potential Remedial Measures
A lake sedimentation survey determined that about 72% of the volume of Quincy Bay has been filled with sediment deposits. Remaining water depths range from 0.5 foot in Long Lake and Triangle Lake to 5.6 feet in the lower main bay. Measurements of water and sediment fluxes into the bay showed that tributaries contribute 1% of the water and 8% of the sediment, the access channel contributes 52% of the water and 22% of the sediment, and flood overflows from the Mississippi River contribute 47% of the water and 70% of the sediment The average annual sediment inflow is 1,096,000 tons, of which about 245,000 tons, or 22.4%, is deposited in the bay. A number of possible remedial measures, and comments on them from interested agencies and individuals, are presented and discussed in the report. Recommended actions include: 1) rehabilitation of Triangle Lake, 2) selective dredging for boating and fish habitat, 3) implementation of soil conservation practices on tributary watersheds, and 4) further analysis of closing the access channel and diverting all but the largest floods from most of the bay area.publishedpeer reviewedOpe
Vegetation and Acidification
In this chapter, the impact of watershed acidification treatments on WS3 at the Fernow Experimental Forest (FEF) and at WS9 on vegetation is presented and summarized in a comprehensive way for the first time. WS7 is used as a vegetative reference basin for WS3, while untreated plots within WS9 are used as a vegetative reference for WS9. Bioindicators of acidification impacts that will be considered include several measures of tree and stand growth rates, foliar chemistry, bolewood chemistry, and herbaceous species composition and diversity. These studies enhance our understanding of the inter-relationships of changes in soil conditions caused by the acidification treatment and the condition of forest vegetation

Novel pathogenic COX20 variants causing dysarthria, ataxia, and sensory neuropathy.
COX20/FAM36A encodes a mitochondrial complex IV assembly factor important for COX2 activation. Only one homozygous COX20 missense mutation has been previously described in two separate consanguineous families. We report four subjects with features that include childhood hypotonia, areflexia, ataxia, dysarthria, dystonia, and sensory neuropathy. Exome sequencing in all four subjects identified the same novel COX20 variants. One variant affected the splice donor site of intron-one (c.41A>G), while the other variant (c.157+3G>C) affected the splice donor site of intron-two. cDNA and protein analysis indicated that no full-length cDNA or protein was generated. These subjects expand the phenotype associated with COX20 deficiency

Ernst Freund as Precursor of the Rational Study of Corporate Law
Gindis, David, Ernst Freund as Precursor of the Rational Study of Corporate Law (October 27, 2017). Journal of Institutional Economics, Forthcoming. Available at SSRN: https://ssrn.com/abstract=2905547, doi: https://dx.doi.org/10.2139/ssrn.2905547The rise of large business corporations in the late 19th century compelled many American observers to admit that the nature of the corporation had yet to be understood. Published in this context, Ernst Freund's little-known The Legal Nature of Corporations (1897) was an original attempt to come to terms with a new legal and economic reality. But it can also be described, to paraphrase Oliver Wendell Holmes, as the earliest example of the rational study of corporate law. The paper shows that Freund had the intuitions of an institutional economist, and engaged in what today would be called comparative institutional analysis. Remarkably, his argument that the corporate form secures property against insider defection and against outsiders anticipated recent work on entity shielding and capital lock-in, and can be read as an early contribution to what today would be called the theory of the firm.Peer reviewe
