Assessing Subterranean Arthropod Diversity through COI Barcoding in Two Ecoregions of Southwestern Virginia, USA
… gene: cytochrome C oxidase subunit I (COI) from each recovered morphospecies and derived a unique COI barcode for each species sequenced. Objective sequence clustering was used to establish molecular operational taxonomic units (mOTUs) for downstream diversity analyses and establishment …

Phylogenetic Relationships of Tick Species in the <em>Ixodes ricinus</em> Complex, Derived from Mitochondrial Coi and 16S Genes
… cytochrome oxidase subunit I (mtDNA COI), and mitochondrial (mt) 16S genes. Ten species from the complex were analyzed; a 504bp fragment was amplified from the mt 16s gene and a 1080pb fragment from mtDNA COI gene. The inferred phylogeny showed that members of the <em>Ixodes</em> …

DNA Barcode Examination of North American Mayflies Across Their Natural Distribution Reveals Cryptic Species Complexes
… and sequence cytochrome c oxidase subunit 1 (COI), a mitochondrial DNA (mtDNA) encoded subunit of respiratory Complex IV. COI has proven useful as a marker for identification purposes because the frequency of mutations for this gene is relatively high. Thus, conserved mutations and variability …

Introducing a framework for improving competitive programming education for the Cyprus Olympiad in Informatics
… within the Cyprus Olympiad in Informatics (COI) (Eracleous et al., 2019). The proposed COI framework intends to redefine the teaching and learning processes within its discipline. The research focuses on four critical pillars: the pedagogical model of a learning community, the instructional …

Comparison of the abilities of historical and current cost information to predict funds flows
This study compared current operating income (COI), current operating income plus realizable holding gains measured in constant dollars and purchasing power gain (i.e., current real income (CRI)), and historical cost income measured in nominal dollars (HCI) on their ability to predict future funds …

Developing a Faculty-Librarian Community of Inquiry: A Blended Learning Approach to Facilitate Information Literacy Education
… of a blended Community of Inquiry (CoI) (Garrison, 2011) Faculty-Librarians CoI Workshop (FacLibCoI) within a social constructivist epistemology. A mixed methods, design-based research (DBR) approach was used to build and test the FacLibCoI prototype and was based on Pool and …

The Effect of Blackboard Tools on the Community of Inquiry and Learner Satisfaction with Learning Management System-Enabled Courses
… & Straut, 2016). The Community of Inquiry (CoI) theoretical framework is composed of interrelated cognitive, teaching, and social presences, which make up a deeper learning experience (Garrison, Anderson, & Archer, 2010). This study sought to further the theoretical and practical application …

Using personal orientation and career anchors to predict commitment and performance in life insurance salespeople
… salespersons. The Career Orientation Inventory (COI) and the Organizational Commitment Scale (OCS) were used to identify the respective career anchors and the commitment dimensions. A series of factor analyses confirmed the original OCS scale constructs, but not those of the POP and the cor. The …

The interpersonal and mental health implications of the coherence of coming out narratives for a sample of gay men in committed romantic relationships
… state of mind, to code a Coming Out Interview (COI). In the present study current state of mind refers to the degree of coherent discourse produced about coming out experiences as relayed during the COI. Multilevel analyses tested the extent to which these COI dimensions, as revealed through an …

Host-parasite cophylogeny and rates of evolution in two rodent-louse assemblages
… when compared to their hosts. The mitochondrial COI gene of lice of the G. coronadoi complex is evolving approximately 2 -3 times faster than the COI gene of their hosts, whereas the COI gene of lice of the G. mexicanus complex is evolving at roughly the same rate as the same gene of their hosts. …

Contribution to the systematics of the genus Aphis (Hemiptera:Aphididae)
… Parsimony and MrBayes of cytochrome oxidase I (COI), nuclear elongation factor (EF1-∝) and primary endosymbiont Buchnera 16S (Buch 16S) were not congruent. MrBayes strongly supported most of terminal nodes of the phylogenetic trees. The phylogeny was strongly supported by detailed morphological …

Phylogeography of Darlingtonea Kentuckensis and Molecular Systematics of Kentucky Cave Trechines
… mitochondrial gene cytochrome oxidase subunit I (COI) was collected from one to four individuals from 27 populations, and patterns of phylogeography and population structure were inferred from COI haplotypes. A hierarchical analysis of molecular variance found low nucleotide diversity within …

Improving the efficiency of domestic ovens
… Dr Mark Williamson of Cambridge Oven Innovation (COI). Initially computational models were used to predict the efficacy of the design concept. Heat transfer coefficients from literature and a computational fluid dynamics (CFD) simulation were imported into a lumped property model, which predicted …

DNA barcoding of forensically important flies in the Western Cape
… DNA barcode, cytochrome c oxidase subunit I (COI) and a secondary marker, the second internal transcribed spacer (ITS2) were analysed. Phylogenetic analyses for both barcodes showed high interspecific divergence values which are desirable for species level differentiation by DNA barcoding. COI …
