Jonesin': the life and music of Philly Joe Jones
No full textThis thesis explores the life of drummer “Philly” Joseph Rudolf Jones, one of jazz’s most renowned, unknown figures. As the drummer for the Miles Davis Quintet/Sextet and a later incarnation of the Bill Evans Trio, Joe achieved worldwide fame and success. Yet, his life story has always been told in the footnotes of the towering figures he performed with: John Coltrane, Bud Powell, Charlie Parker, Thelonious Monk, etc. Jazz history books recognize Joe’s contributions and nearly all provide a space, albeit a small one, to recognize his accomplishments. Leonard Feather’s The Encyclopedia of Jazz has an entry for Joe, Lewis Porter’s An Historical Survey of Jazz Drumming Styles lists Joe as an important figure in the evolution of jazz drumming, and The Oxford Companion to Jazz states that “just about anyone of consequence worked with Jones.” These texts and many others put Joe in a place of prominence for a handful of sentences. However, footnoting Joe’s success overlooks the fact that he recorded on more than one-hundred albums from 1955-1960 and was probably the most recorded American drummer in any genre during that time period. Despite his popularity and critical acclaim, no published author has delved into Joe’s complex life with any depth. This thesis explores Joe’s musical biography and seeks to illuminate the paradoxes therin. Joe’s story contains drug use, prison time, and abrasive behavior. On the other hand, he was an excellent musician and a generous man who mentored many young musicians. Joe’s life is intertwined in a web of circumstantial experiences: a fatherless upbringing, military service during World War II, integrating the Philadelphia Transit Company, and working to survive as a musician in New York. There are also lesser-known parts of his life including his roots as a Rhythm and blues drummer, his love for big band music, and his associations with the avant-garde. Joe overcame the obstacles of socioeconomic status, racism, evolving musical styles, and the drug culture to become a superb musician who still found time to educate the next generation.M.A.Includes bibliographical referencesIncludes vitaby Dustin E.

No full textInfluences of host community characteristics on Borrelia burgdorferi infection prevalence in Blacklegged ticks
No full textLyme disease is a major vector-borne bacterial disease in the USA. The disease is caused by Borrelia burgdorferi, and transmitted among hosts and humans, primarily by blacklegged ticks (Ixodes scapularis). The ~25 B. burgdorferi genotypes, based on genotypic variation of their outer surface protein C (ospC), can be phenotypically separated as strains that primarily cause human diseases – human invasive strains (HIS) – or those that rarely do – and are non-randomly associated with host species. The goal of this study was to examine the extent to which phenotypic outcomes of B. burgdorferi could be explained by the host communities fed upon by blacklegged ticks. In 2006 and 2009, we determined the host community composition based on abundance estimates of the vertebrate hosts, and collected host-seeking nymphal ticks in 2007 and 2010 to determine the ospC genotypes within infected ticks. We regressed instances of B. burgdorferi phenotypes on site-specific characteristics of host communities by constructing Bayesian hierarchical models that properly handled missing data. The models provided quantitative support for the relevance of host composition on Lyme disease risk pertaining to B. burgdorferi prevalence (i.e., overall nymphal infection prevalence, or NIPAll) and HIS prevalence among the infected ticks (NIPHIS). In 2006, we found positive associations of the relative abundances of mice, of chipmunks, and of shrews with NIPAll. We also found positive associations of NIPHIS with shrews, and with host community diversity (H’), but negative associations with mice, and with chipmunks. In 2009, the relative abundance of mice showed a positive association with NIPAll, whereas the relative abundance of shrews and of H’ showed a negative association. With NIPHIS, only H’ showed a positive association, whereas the relative abundances of mice, of chipmunks, and of shrews, had negative associations. Our study highlights the variability between two years in the effects of host composition on B. burgdorferi genotypes. More importantly, our results highlight how disease risk inference, based on the role of host community, changes when we examine risk overall or at the phenotypic level. Long-term studies will be necessary to detect any consistent effects of host community composition on genotypic variation in the Lyme disease spirochetes
Framing ethanol : a content analysis comparing national and regional media coverage of ethanol
No full textThe main purpose of this research study was to compare national and regional newspaper coverage of the issue of ethanol. The methodology used in this study was content analysis. Newspaper articles were the units of analysis. Newspaper articles printed in four national newspapers and four regional newspapers located in the top ethanol producing states in the United States were collected from a LexisNexis Academic database and analyzed. Newspaper articles were analyzed in terms of article source, size, placement in terms of section and page number, headline and author attributes, the number and types of sources included in each story, overall article tone and themes. Results from the content analysis found no significant correlations between national and regional newspapers and the tone, source types and themes of ethanol articles. Data did show differences in other affective attributes attached to the issue of ethanol.Thesis (M.A.)Department of Journalis
Morphology of mitochondria and cell respiration,pt.1.
No full textTo reveal the mechanism of liver damage by taking CCl4 the author observed the liver tissues from rats at 1.5, 5, 6, 10, 17, 20, and 22 hours after the CCl4 administration, both by light microscope and electron-microscope. 1. Light microscope observation revealed the swelling of liver cells in the carly stage, the appearance of centrolobular fatty degeneration, focal degeneration area and the appearance of balloon cells, with the circulatory disturbances in accompanying stages and hemorrhage in the later stage. 2. Electron-microscope observation revealed the swelling of mitochondria, appearance of the files of thin ER's in the early stage and the regeneration and degeneration of mitochondria with an increase of microbodies in number. Fat droplets are developed from small ones probably from some microbodies without correlation with mitochondria. 3. From these observations the author is of the opinion that CCl4 arrests the cells at first inducing the swelling of cells and their mitochondria, but later the degenerative changes will become severe being complicated by the anoxia which is induced by the circulatory disturbances caused by the compression of vessels with the swollen cells.</p
New Insight into an Old Problem: Analysis, Interpretation, and Theoretical Modeling of the Absorption and Magnetic Circular Dichroism Spectra of Monomeric and Dimeric Zinc Phthalocyanine Cation Radical
No full textThe
chemically or spectroelectrochemically generated formation and aggregation
of zinc(II) tetra-tert-butylphthalocyanine cation
radical [ZnPctBu]+•, which was highly
soluble in common organic solvents, were investigated using UV−vis
and magnetic circular dichroism (MCD) spectroscopies with an emphasis
on the influence of the axial ligand on the fingerprint (∼500
nm) and NIR (720∼1000 nm) spectral envelopes. MCD spectroscopy
is suggestive that the NIR band at ∼1000 nm observed for the
antiferromagnetically coupled cation radical dimer, [ZnPctBu]22+, has no degeneracy, the monomer–dimeric
equilibrium is temperature dependent, and higher degree aggregates
can be formed at specific conditions. Sixteen different exchange-correlation
functionals were tested to accurately predict the energies, intensities,
and profiles of the UV–vis and MCD spectra of the phthalocyanine
cation radical monomer and dimer. It was found that the M05 exchange-correlation
functional (along with several other functionals that include 27–42%
of Hartree–Fock exchange) provided an excellent agreement (∼0.1
eV for the degenerate excited states observed by MCD spectroscopy)
between theory and experiment for the phthalocyanine cation-radical
monomer and dimer. Not only did time-dependent density functional
theory (TDDFT) calculations with M05 exchange-correlation functional
correctly predict the nondegenerate NIR charge-transfer band at ∼1000
nm, all degenerate excited states, monomer and dimer energies, and
oscillator strengths, but also they correctly described the nature
of the experimentally observed at ∼500 nm MCD B-term (fingerprint band) detected for both the monomeric and dimeric
phthalocyanine cation radicals. The TDDFT data explain the similarities
in the UV–vis and MCD spectra of the monomeric and dimeric
species observed between the UV and fingerprint spectral envelopes
as well as correctly predicted the antiferromagnetic coupling between
the two singly oxidized phthalocyanine macrocycles in the dimer
Charge-Transfer Spectroscopy of Bisaxially Coordinated Iron(II) Phthalocyanines through the Prism of the Lever’s <i>E</i><sub>L</sub> Parameters Scale, MCD Spectroscopy, and TDDFT Calculations
No full textThe position of the experimentally
observed (in the UV–vis
and magnetic circular dichroism (MCD) spectra) low-energy metal-to-ligand
charge-transfer (MLCT) band in low-spin iron(II) phthalocyanine complexes
of general formula PcFeL2, PcFeL′L″, and
[PcFeX2]2– (L, L′, or L″
are neutral and X– is an anionic axial ligand) was
correlated with the Lever’s electrochemical EL scale values for the axial ligands. The time-dependent
density functional theory (TDDFT)-predicted UV–vis spectra
are in very good agreement with the experimental data for all complexes.
In the majority of compounds, TDDFT predicts that the first degenerate
MLCT band that correlates with the MCD A-term observed
between 360 and 480 nm is dominated by an eg (Fe, dπ) → b1u (Pc, π*) single-electron excitation
(in traditional D4h point group notation)
and agrees well with the previous assignment discussed by Stillman
and co-workers[Inorg. Chem. 1994, 33, 573–583]. The TDDFT calculations also suggest a small
energy gap for b1u/b2u (Pc, π*) orbital splitting
and closeness of the MLCT1 eg (Fe, dπ) → b1u (Pc, π*) and MLCT2 eg (Fe, dπ) → b2u (Pc,
π*) transitions. In the case of the PcFeL2 complexes
with phosphines as the axial ligands, additional degenerate charge-transfer
transitions were observed between 450 and 500 nm. These transitions
are dominated by a2u (Pc
+ L, π) → eg (Pc, π*) single-electron excitations and are unique for the
PcFe(PR3)2 complexes. The energy of the phthalocyanine-based a2u orbital has large axial
ligand dependency and is the reason for a large energy deviation for
B1 a2u (Pc + L, π)
→ eg (Pc, π*)
transition. The energies of the axial ligand-to-iron, axial ligand-to-phthalocyanine,
iron-to-axial ligand, and phthalocyanine-to-axial ligand charge-transfer
transitions were discussed on the basis of TDDFT calculations
Here and Not Here - How Mina Loy reconciles Aesthetic Impersonality with the assertion of Female Subjectivity
No full textAccording to Christina Walter (2009), the tension between artistic conveyance of the
universal and transcendent and the assertion of marginalized subjectivity particularly
concerned Mina Loy. The aim of this study is to explore how Mina Loy understood and
reconciled this tension. By surveying a selection of Loy’s nonfiction work, the present project
will use a Jungian approach to literary criticism inspired by the work of Susan Roland (2019)
to explore personhood and individual being, identify how those individuals are who they are
by analyzing relationships, and treat culture through seeking what is lost, marginalized or yet
to come into being. I map these three trajectories onto Loy’s work using the following
concepts: understanding of the construction of a (female) self, the aesthetic/relative
impersonality problem, and her idea of what could be if the contemporary social and artistic
paradigm was shifted to include the female voice, before eventually moving past gender
altogether. Relevant ideas from the “Feminist Manifesto” or “Pyscho-Democracy” are used to
understand Loy’s theories, while sections from “Mi & Lo” are analyzed as examples of these
theories in the context of artistic expression. Doing so illuminates not only the passive role
the artist plays in relationship to artistic expression and the creative process, but also the
ramifications of this passivity on the assertion of female subjectivity in a patriarchal society.
Simply put: how can the female author achieve the disconnect required to be an authentic
(modern) artist while simultaneously asserting the female perspective into the
male-dominated discussion
Catalytic Synthesis of Donor-Acceptor-Donor (D-A-D) and Donor-Acceptor-Acceptor (D-A-A) Pyrimidine-Ferrocenes via Acceptorless Dehydrogenative Coupling: Synthesis, Structures, and Electronic Communication
No full textThe synthesis and full characterization of a series of ferrocene-decorated pyrimidines with donor-acceptor-donor (D-A-D) and donor-acceptor-acceptor (D-A-A) architectures are reported. The three novel compounds share a pyrimidine core and single ferrocenyl donor arm, with an additional substituent varied from donor ferrocene (1) to acceptor pyrenyl (2) to donor (4-diphenylamino)phenyl groups (3). The compounds could be easily constructed in acceptable yields in one-pot reactions via acceptorless dehydrogenative coupling reactions mediated by a ruthenium coordination complex supported by a simple bidentate P^N ligand. The solution and solid-state structures of the new pyrimidines are described along with photophysical and computational characterization. The lack of near IR (NIR) transitions upon single-electron oxidation of the compounds implies that the pyrimidinyl unit is less effective at mediating electronic communication compared with pyridine or pyrrole cores. Nevertheless, strong absorption in the far visible and NIR is observed upon formation of a dicationic species from 3 and is attributed to efficient charge transfer from the pyrimidine core to the oxidized donor units.Natural Sciences and Engineering Research Council of Canada (RGPIN-2014-03733
