Type status and taxonomic accounts for Ambiserrula jugosa (McCulloch 1914) and Inegocia harrisii (McCulloch 1914) (Scorpaeniformes: Platycephalidae)
No full textPlatycephalids Ambiserrula jugosa (McCulloch 1914) and Inegocia harrisii (McCulloch 1914) were described as new species based on 10 and 2 specimens, respectively, collected from the coast of Queensland, Australia by the F.I.S. Endeavour in 1910. McCulloch (1914) listed additional specimens at the end of the description, which he did not exclude from the type series. Previous authors considered the specimens, which McCulloch stated the species to have been described from, to be types of the two species, it was revealed that all 43 and 9 specimens included in these species by McCulloch are type specimens, according to the fourth edition of International Code of Zoological Nomenclature, stating "type series of a nominal taxon consists of all the specimens included by the author in the new nominal taxon" in Article 72.4.1. In I. harrisii, it was assumed that a specimen later designated as the lectotype was figured with the original description. Because its plate legend includes the words "sp. nov. Type", the specimen is regarded to be the holotype of the species and the designation of the lectotype was unnecessary. This study newly recognizes additional 12 paratypes of A. jugosa and 5 paratypes of I. harrisii, and gives taxonomic accounts of the two species to show range extensions of intraspecific variation and distribution newly found. Also comments are given about the type status of other species taken by the Endeavour described by McCulloch in a series of five papers

McCulloch v. Maryland at 200 ::debating John Marshall's jurisprudence /
No full textIn recognition of the 200th anniversary of the Supreme Court's landmark decision in McCulloch v. Maryland, AEI's Program on American Citizenship commissioned five distinguished scholars to author essays keyed to that decision. The program hosted a panel discussion with the authors to present their initial drafts in February 2019. The chapters of this edited volume are the finalized versions of those essays
Lake Havasu City McCulloch Corridor improvement study : final report
No full textabstract: The Arizona Department of Transportation, in cooperation with Lake Havasu City, conducted a long-range corridor study for Mesquite Avenue, McCulloch Boulevard, and Swanson Avenue (referred to in this document collectively as the Corridor). The study looked at ways to support and enhance this revitalization by developing a vision for the Corridor that balances the City’s Main Street Uptown District goals with the need to accommodate future travel demand along each road in the Corridor
Taking stock of open access : progress and issues
No full textPurpose - Aims at providing a broad overview of some of the issues emerging from the growth in open access publishing, with specific reference to the use of repositories and open access journals. Design/methodology/approach - A paper largely based on specific experience with institutional repositories and the internationally run E-library and information science (LIS) archive. Findings - The open access initiative is dramatically transforming the process of scholarly communication bringing great benefits to the academic world with an, as yet, uncertain outcome for commercial publishers. Practical implications - Outlines the benefits of the open access movement with reference to repositories and open access journals to authors and readers alike and gives some food for thought on potential barriers to the complete permeation of the open access model, such as copyright restrictions and version control issues. Some illustrative examples of country-specific initiatives and the international E-LIS venture are given. Originality/value - An attempt to introduce general theories and practical implications of the open access movement to those largely unfamiliar with the movement
Marine diterpene glycosides
No full textMarine diterpene glycosides (MDGs) respresent a small but highly significant group of the much larger class of marine diterpenes. The three well-studied examples of MDGs are eleutherobins, pseudopterosins and fuscosides, all of which exhibit extremely promising biological activity. The eleutherobins are potent anti-mitotic agents, and the pseudopterosins and fuscosides are potent anti-inflammatory agents. This review discusses the structures and biological activities of these compounds, as well as their biosynthesis and synthesis
One-pot syntheses of pseudopteroxazoles from pseudopterosins : a rapid route to non-natural congeners with improved antimicrobial activity
No full textRapid one-pot methodologies to prepare pseudopteroxazole (1) and novel congeners from abundant natural pseudopterosins have been devised. This is highlighted here with the first synthesis of the marine natural product homopseudopteroxazole (2) utilizing a novel, silver(I)-mediated catechol to benzoxazole transformation. Pseudopteroxazoles and isopseudopteroxazoles exhibit potent activity against a range of important Gram-positive pathogens including Mycobacterium spp. and vancomycin-resistant Enterococcus faecium. Several non-natural pseudopteroxazoles exhibited strong activity against methicillin-resistant Staphylococcus aureus, thereby displaying a broader spectrum of antibiotic activity compared to pseudopteroxazole

The Kalman Foundations of Adaptive Least Squares: Applications to Unemployment and Inflation
No full textAdaptive Least Squares (ALS), i.e. recursive regression with asymptotically constant gain, as proposed by Ljung (1992), Sargent (1993, 1999), and Evans and Honkapohja (2001), is an increasingly widely-used method of estimating time-varying relationships and of proxying agents’ time-evolving expectations. This paper provides theoretical foundations for ALS as a special case of the generalized Kalman solution of a Time Varying Parameter (TVP) model. This approach is in the spirit of that proposed by Ljung (1992) and Sargent (1999), but unlike theirs, nests the rigorous Kalman solution of the elementary Local Level Model, and employs a very simple, yet rigorous, initialization. Unlike other approaches, the proposed method allows the asymptotic gain to be estimated by maximum likelihood (ML). The ALS algorithm is illustrated with univariate time series models of U.S. unemployment and inflation. Because the null hypothesis that the coefficients are in fact constant lies on the boundary of the permissible parameter space, the usual regularity conditions for the chi-square limiting distribution of likelihood-based test statistics are not met. Consequently, critical values of the Likelihood Ratio test statistics are established by Monte Carlo means and used to test the constancy of the parameters in the estimated models.Kalman Filter, Adaptive Learning, Adaptive Least Squares, Time Varying Parameter Model, Natural Unemployment Rate, Inflation Forecasting
