Establishing Practical Equivalence Of Factor Loadings In Multigroup Confirmatory Factor Analysis, Christopher Edward Shank

Dissertations

This dissertation compares the performance of equivalence test (EQT) and null hypothesis test (NHT) procedures for identifying invariant and noninvariant factor loadings under a range of experimental manipulations. EQT is the statistically appropriate approach when the research goal is to find evidence of group similarity rather than group difference; despite this, the conventional approach to measurement invariance analysis relies upon NHT. EQT has proved effective for invariance detection using global model-data fit statistics in simulated and real-world data (Counsell et al., 2020) but its use in partial measurement invariance (PMI) analysis for evaluation of factor loading differences between groups has …

Shigella Flexneri Diguanylate Cyclases Regulate Pathogenesis, Ruchi Ojha

Dissertations

The intracellular human pathogen Shigella invades the colonic epithelium to cause disease. Prior to colon invasion, this bacterium navigates through different environments within the human body, including acidic conditions in the stomach and the small intestine which contains antimicrobial molecules including bile acids. To adapt to changing environments, Shigella uses the bacterial second messenger c-di-GMP signaling system. C-di-GMP is synthesized by diguanylate cyclases (DGCs) encoding GGDEF domains. Shigella encodes 10 DGCs in its genome, but 6 of these genes have acquired mutations that presumably inactivated the c-di-GMP synthesis activity of these enzymes. In this study, we first expressed VCA0956, a …

On The Projections And Unitary Groups Of Unital C*-Algebras, Fouzia Shaheen

Dissertations

H. Dye proved that the unitary group in a factor determines the algebraic type of that factor. Al-Rawashdeh, Booth and Giordano established that, for a large class of simple unital C*-algebras, an isomorphism between the unitary groups induces an isomorphism between their K₀-ordered group and 1-groups. Then using the results of Dadarlat-Elliot-Gong and Kirchberg-Phillips, the C*-algebras are isomorphic. Dye introduced special projections P_i,j (a) of the matrix algebra M_n(A), and he used it as a main tool to establish his results in the case of von Neumann factors.
