Beloved Community: Martin Luther King, Howard Thurman, and Josiah Royce
No full textMartin Luther Kings primary emphasis was upon beloved community, a phrase he borrowed from Royce, but an idea that he shared with St. Augustine. Theories of the state tend to focus upon division, in which one stratum dominates another or others. Kings context is the US in the segregated Southa region whose internal divisions sharply instantiate the idea of the state as an unequal hierarchy of dominance. Kings appeal was less to end black subjugation than to end subjugation as such. Hence King was called by some a dreamer, given his background commitment to equality and community, ideals taking marginal precedence over his foreground commitment to liberty and autonomy. This article explores the notion of beloved community broadly and then specifically in Martin Luther King along with related notions in Howard Thurman (1900-1981) and in Josiah Royce (1855-1916).

Working memory training increases general learning abilities in CD-1 outbred mice:
No full textGeneral intelligence is a cognitive trait that is purported to influence most domain-specific learning abilities in humans. Like humans, CD-1 outbred mice express individual differences in their "general" cognitive abilities, such that performance across diverse batteries of learning tasks tend to be positively correlated, and this general learning factor accounts for 32-48% of the variance of individual animals performance in cognitive test batteries. It has been demonstrated that in both humans and mice, the efficacy of working memory capacity correlates highly with measures of general cognitive ability. In three experiments, here we demonstrate that in genetically heterogeneous mice, repetitive working memory training promotes an increase in selective attention and has a commensurately positive effect on the animals' aggregate performance on a battery of five learning tasks. The enhancement of general cognitive performance by working memory exercise was attenuated if the selective attention demands of that exercise were reduced. Finally, because much of the human research conducted on working memory training is done in pre-pubescent children, we trained a group of mice beginning in pre-pubescence and found no difference between that group and one trained at our typical young-adult age. In total, these results provide initial evidence that the efficacy of working memory capacity and selective attention are causally related to an animal’s general cognitive performance, and suggest behavioral strategies to promote those abilities.Ph.D.Includes bibliographical references (p. 63-65)by Kenneth Royce Ligh
The Mineral Susceptibility Database
No full textThe Mineral Susceptibility Database (MSD) consolidates current relevant research from various fields (including museums, earth science, chemistry, and material science) into one freely accessible location. Its aim is to be a comprehensive reference for museum professionals—and a starting point for further research—when assessing the conditions required by their mineral collections and objects.
The data were collected from January 2019 to May 2021 by reviewing various journal articles and publications for relevant data, which was then synthesised and inserted into the correct fields of the Database. The Database was created and designed in Microsoft Excel. This was exported into a PDF to ensure reliability (by avoiding any 3rd party tampering) and format preservation, and to allow for broader access (as most web browser are capable of reading PDFs).
While the data presented in the MSD is replicated in good faith from trusted sources, it is recommended for one to return to the original source document and confirm parameters with the corresponding author

No full textComparing sample mediums for detecting invertebrates using eDNA on Prince Edward Island
No full textEnvironmental DNA (eDNA) as a biodiversity monitoring strategy can be a time-saving and
cost-saving resource when compared to morphometric identification. Aquatic survey programs
are hesitant to adopt metabarcoding-based eDNA sequencing as an official monitoring strategy
due to molecular method shortcomings, namely amplification bias, sequencing material costs and
incomplete reference databases. This study aims to develop a protocol for metabarcoding coastal
crustaceans on Prince Edward Island using novel COI gene metabarcoding primers designed by
Fisheries and Oceans Canada. Next-generation sequencing results from sediment, water, and
unsorted bulk tissue extracts are compared to small-bodied crustacean traps and known PEI
crustacean assemblages. Sampling occurred in June and August of 2021, with two additional
sample time points from the summers of 2016 and 2017 to provide preliminary spatiotemporal
community comparisons. The goal of this study is to develop a protocol using eDNA that may
expedite aquatic crustacean biodiversity surveys and supplement the techniques currently
employed in the watersheds on Prince Edward Island
Infinity and the Self: Royce on Dedekind
No full textInternational audienceIn Die Zahlen (1888), Dedekind defines an infinite set as a set that is isomorphic with one of its proper parts. In The World and the Individual (1900), the American philosopher Josiah Royce relates Dedekind’s notion to Fichte’s and Hegel’s concept of Self defined as an entity that reflects itself into itself. The first aim of this article is to explain Royce’s analysis and to put it in its proper context, that of a critique of Bradley’s mystical idealism. The second aim is to urge a shift in focus in Dedekind’s scholarship: instead of addressing the question of the relationship between mathematics and philosophy in Dedekind’s work through the supposed intentions of its author, it is more fruitful to analyze the reception that philosophers have made of his texts

An Intrageneric and Intraspecific Study of Morphological and Genetic Variation in the Neotropical Compsoneura and Virola (Myristicaceae)
No full textThe Myristicaceae, or nutmeg family, consists of 21 genera and about 500 species of dioecious canopy to sub canopy trees that are distributed worldwide in tropical rainforests. The Myristicaceae are of considerable ecological and ethnobotanical significance as they are important food for many animals and are harvested by humans for timber, spices, dart/arrow poison, medicine, and a hallucinogenic snuff employed in medico-religious ceremonies. Despite the importance of the Myristicaceae throughout the wet tropics, our taxonomic knowledge of these trees is primarily based on the last revision of the five neotropical genera completed in 1937. The objective of this thesis was to perform a molecular and morphological study of the neotropical genera Compsoneura and Virola. To this end, I generated phylogenetic hypotheses, surveyed morphological and genetic diversity of focal species, and tested the ability of DNA barcodes to distinguish species of wild nutmegs. Morphological and molecular analyses of Compsoneura. indicate a deep divergence between two monophyletic clades corresponding to informal sections Hadrocarpa and Compsoneura. Although 23 loci were tested for DNA variability, only the trnH-psbA intergenic spacer contained enough variation to delimit 11 of 13 species sequenced. A morphological and molecular investigation of Compsoneura capitellata showed little discrete morphological variation among populations but significant genetic structure among populations. Phylogenetic analysis of Virola also revealed a deep molecular divergence between two clades having numerous contrasting morphologies. In contrast to Compsoneura, the trnH-psbA intergenic spacer failed to differentiate the majority of Virola species tested. An infraspecific morphological and molecular study of V. sebifera and V. loretensis showed that each of these species contains morphologically and ecologically discrete sympatric morphotypes that likely represent new species. In total, this investigation found 5 provisional new species from fewer than 600 collections at biological stations in Ecuador and Peru where these new species were among the most abundant trees in the forest. This suggests that much diversity likely remains to be described in the Myristicaceae and other tropical plant families
