Despite being recognized as one of the most important compositions in the twentieth¬ century wind band repertoire, the William Byrd Suite presents many obstacles for the conductor and ensemble members. Since its initial publication in 1924, the piece has contained many discrepancies of pitch, articulation, rhythm, dynamics, and phrase completion that appear in the score as well as the parts. Although the work was reissued by Boosey & Hawkes in 1960 and 1991, many of the original errors remained intact. The sheer amount of inconsistencies causes great difficulties for the musicians involved in the rehearsal process, slowing efficiency and resulting in a frustrating impediment to a quality performance. The primary purpose of this study was the creation of a critical edition of Jacob's William Byrd Suite that eliminates errors of extant editions, incorporates modern instrumentation, and considers the source material. To accomplish this, the present project looks at all sources, including the autograph manuscript, orchestral version, published editions, and errata. The editorial process examines the governing philosophy, subsequent editorial decisions and indications, and the final organization of the parts. The study concludes with the inclusion of the full score of the new critical edition.

Indiana University-Purdue University Indianapolis (IUPUI) / Petrography of the sand fraction, particle size analysis, and detrital zircon U/Pb isotope data, and pebble count data were collected from Byrd Glacier moraines and central/western Ross Sea till in order to study the glacially-driven sedimentological dynamics of the Byrd Glacier and to trace material transported from the Byrd Glacier into the Ross embayment. Most of the petrographic data show evidence of local derivation with the exception of the sites from the Lonewolf Nunataks as indicated by exotic rock types within the sand and pebble fractions. This, in conjunction with particle-size data of the samples from the Lonewolf Nunataks indicate that material from underneath the East Antarctic Ice Sheet (EAIS) is being transported to the surface and deposited in this area. The U/Pb ages of zircons from the Byrd Glacier show dominant populations of Ross to Pan-African ages (~533 - 610 Ma) with varying populations of older (Grenville to Archean) zircons. Late Precambrian (~588 – 610 Ma) aged detrital zircons in samples from the head of the Byrd Glacier are older than other dated grains found in the vicinity and may be evidence of early development of the Ross belt or represent evidence of sub-glacial extension of the Mozambique structure found in Dronning Maud Land. The west central Ross Sea till samples have a variety of mineral and lithic fragments that include a dominant population of polymict at certain depth intervals. Detrital zircon data suggests the potential provenance of two of these intervals may be derived from Marie Byrd Land and possibly the Byrd Glacier. Using sand petrography and U/Pb detrital zircon age dating, positive correlation was found between specific samples from the head of the Byrd Glacier and the western Ross Sea. The ice-sheet flow models of Stuiver et al. (1981), Licht and Fastook (1998), and Licht et al. (2005) each show potential support from aspects of this study. It is possible that dynamic ice-flow regime changes of the West and East Antarctic Ice Sheets into the Ross Sea may have occurred some time during the LGM as suggested by geochemical and petrographical evidence found within intervals of central and western Ross Sea cores.

This thesis is a study of the usage of sixteenth-century polyphonic devices as employed by the English composer William Byrd and the Italian composer Pierluigi Palestrina. Both men represented a culmination of sixteenth-century contrapuntal composition in their respective school and period, Byrd of the Renaissance Tudor period, and Palestrina of the Roman school and Renaissance period. Palestrina's work became a pattern for sacred Roman music during the late Renaissance because of its consistency, its origin in the modes, and its compositional style. As it became a popular standard for Latin liturgical music, Catholic composers of all nationalities began to use it as a guide for their writing. At this time in England, one such young composer named William Byrd began to emulate Palestrina. Up to this time few of the English composers had taken advantage of the progress made by the musicians of the Netherlands school. These two composers lived about the same time, and their vocal works are quite comparable, yet there was never any known contact between them. There seem to be some notable differences, but each of these is as consistent as the similarities. Both men were prolific writers of motets, which mirrored all of the Roman Catholic Church activities in an ecclesiastical year. Twelve motets by each composer, six from the early works and six from the late works of each, were chosen for contrast and comparison. In his book, Direct Approach to Counterpoint in 16th-Century Style, C.F. Soderlund set forth a conclusive and concise set of rules which he felt particularly characterized the music of Palestrina. A select group of rules or practices, some pertaining to the melodic line and others concerned with dissonances, was chosen from Soderlund's book to be used as a basis for comparison and contrast of the motets of Palestrina and Byrd.

Virginia's Pupil Placement Board was the most enduring vestige of the state's "massive resistance" movement in the 1950s. Following the example of other Southern states, the state's General Assembly passed the Pupil Placement Act in 1956 as part of a package of legislation designed to counteract the Supreme Court desegregation ruling. The Act, and the Pupil Placement Board that enforced it, lasted a decade, much longer than any of the other legislative initiatives born during that session, longer than the massive resistance movement itself.Whites, including many of Virginia's leaders, considered the Board to be ineffective at stemming the onslaught of integration, while African-Americans felt that the agency breeched their constitutional rights. From its inception to its dissolution in 1966, the Pupil Placement Board had to defend itself in a slew of desegregation cases all over Virginia, and the General Assembly changed the law several times to comply with court orders. Despite this adversity, the Board was consistently effective in stemming desegregation in Virginia throughout its tenure.

Thesis advisor: Seth C. Kruckenberg / The West Antarctic rift system is one of the most expansive regions of extended continental crust on Earth, but relatively little is known about the structure of the mantle lithosphere in this region. This research aims to examine a suite of ultramafic mantle xenoliths from several volcanic centers located throughout Marie Byrd Land, West Antarctica. Through the use of several complementary analytical methods, the deformational and compositional heterogeneity of the lithospheric mantle in this region is characterized. The Marie Byrd Land xenoliths have equilibration temperatures between 779 and 1198°C, which is a range that corresponds to extraction depths between 39 and 72 km. These samples preserve significant mineralogical and microstructural heterogeneities that document both lateral and vertical heterogeneities within the Marie Byrd Land mantle lithosphere. The modal mineralogy of spinel peridotites varies between 40 – 99% olivine, 0 – 42% diopside, 0 – 45% enstatite and 0 – 5% chromite. Minimum olivine grain sizes range from 60 to 110 µm and maximum olivine grain sizes range from 2.5 to 10.0 mm. The geometric mean grain size of olivine in these samples ranges from 100 µm to 2 mm and has an average of 694 µm. The geometric mean grain size of diopside ranges from 90 to 865 µm and has an average of 325 µm, whereas that of enstatite ranges from 120 µm to 1.2 mm and has an average of 625 µm. Comparatively, the pyroxenites contain 0 – 29% olivine, 29 – 95% diopside, 1 – 36% enstatite and 1 – 11% chromite. Deformation mechanism maps suggest that the olivine within the MBL peridotite xenoliths primarily accommodate strain through the operation of dislocation-accommodated grain-boundary sliding at strain rates between 10-19/s and 10-11/s. This is consistent with microstructural observations of the suite made using optical microscopy (e.g., deformation bands and subgrains in olivine; aligned grain boundaries between contrasting phases). Application of the olivine grain size piezometer indicates that the suite preserves differential stresses ranging from 0.5 MPa to 50 MPa, with mean differential stresses ranging from 4 to 30 MPa. Values of mean differential stress only vary slightly throughout the field area, but generally decrease in magnitude towards the east with maximum values migrating upwards in the lithospheric mantle along this transect. The samples from some volcanic centers are highly homogenous with respect to their microstructural characteristics (e.g., Mount Avers – Bird Bluff), whereas others display heterogeneities on the sub-five-kilometer-scale (e.g., Demas Bluff). Comparatively, mineralogical heterogeneities are more consistent throughout the sample suite with variations generally being observed between the sub-five-kilometer-scale and the sub-ten-kilometer-scale. Most samples within the MBL peridotite suite display axial-[010] or A-type olivine textures. Although less dominant, axial-[100], B-type and random olivine textures are also documented within the suite. Axial-[010] textures have J-indices and M-indices ranging from 1.7 – 4.1 and 0.08 – 0.21, respectively. The average value of the J-index for axial-[010] textures is 2.9, whereas the average M-index of these samples is equal to 0.15. Overall, A-type textures tend to be stronger with J- and M-indices ranging from 1.4 – 9.0 and 0.07 – 0.37, respectively. The olivine crystallographic textures of the MBL xenolith suite are heterogeneous on scales that are smaller than the highest resolution that is attainable using contemporary geophysical methods, which implies that patterns of mantle flow and deformation are far more complex than these studies suggest. / Thesis (MS) — Boston College, 2016. / Submitted to: Boston College.

v.1. Text (246 leaves) -- v.2. Figures and musical examples (145 leaves) / William Byrd's motets with Latin text are a little-known contribution to the sacred vocal repertoire. Most important among these works are three books of Cantiones Sacrae, published 1575, 1589 and 1591, respectively. The 1589 Cantiones Sacrae was Byrd's first harvest from a backlog of motets that had been accumulating since 1575. This collection lies at a midpoint between Byrd's earliest published works and his full maturity, as seen in the Masses of 1592--95. / This study will describe the contrapuntal strategies that characterize Byrd's 1589 Cantiones. I will examine Byrd's deeper-level tonal organization and its derivation from cantus firmus technique. I will show how Byrd uses musical material in cantus firmus values (the breve and semibreve) to shape his subject material and his cadence points, and how this shaping plays out over the course of an imitative point. / I will then examine Byrd's introductory gestures in the 1589 Cantiones, identifying 24 presentation types that characterize different degrees of beginning. These types contain one or more melodic subjects in a recurring temporal relationship, and form a vertical interval pattern or harmonic motive. Next, I will discuss Byrd's variation techniques by which he develops these presentation types: textural change, transposition, melodic inversion and invertible counterpoint. Byrd's presentation and variation of subject material divides an imitative point into distinct phases of tonal and contrapuntal activity, providing insight into its overall form and tonal design. / Finally, I will apply these analytical tools to a complete analysis of Tristitia et anxietas, from the 1589 Cantiones, thereby showing how Byrd establishes central pitches in the middleground. Through this analysis, I will summarize Byrd's contrapuntal strategies, both long-range and local, that typify his middle-period sacred vocal style, as viewed through the lens of the 1589 Cantiones Sacrae.

abstract: The Byrd Glacier region of Antarctica is important for understanding the tectonic development and landscape evolution of the Transantarctic Mountains (TAM). This outlet glacier crossing the TAM marks a major discontinuity in the Neoproterozoic-early Paleozoic Ross orogen. The region has not been geologically mapped in detail, but previous studies have inferred a fault to exist beneath and parallel to the direction of flow of Byrd Glacier. Thermochronologic analysis has never been undertaken across Byrd Glacier, and little is known of the exhumation history of the region. The objectives of this study are to assess possible differential movement across the inferred Byrd Glacier fault, to measure the timing of exhumation, and to gain a better overall understanding of the structural architecture of the TAM. Apatites and zircons separated from rock samples collected from various locations north and south of Byrd Glacier were dated using single-crystal (U- Th)/He analysis. Similar cooling histories were revealed with comparable exhumation rates of 0.03 ± 0.003 and 0.04 ± 0.03 mm/yr north and south of Byrd Glacier from apatite data and somewhat similar rates of 0.06 ± 0.008 and 0.04 ± 0.01 mm/yr north and south of Byrd Glacier from zircon data. Age vs. elevation regressions indicate a vertical offset of 1379 ± 159 m and 4000 ± 3466 m from apatite and zircon data. To assess differential movement, the Kukri Peneplain (a regional unconformity) was utilized as a datum. On-site photographs, Landsat imagery, and Aster Global DEM data were combined to map Kukri Peneplain elevation points north and south of Byrd Glacier. The difference in elevation of the peneplain as projected across Byrd Glacier shows an offset of 1122 ± 4.7 m. This study suggests a model of relatively uniform exhumation followed by fault displacement that uplifted the south side of Byrd Glacier relative to the north side. Combining apatite and zircon (U-Th)/He analysis along with remote geomorphologic analysis has provided an understanding of the differential movement and exhumation history of crustal blocks in the Byrd Glacier region. The results complement thermochronologic and geomorphologic studies elsewhere within the TAM providing more information and a new approach. / Dissertation/Thesis / M.S. Geological Sciences 2011

Doctor of Philosophy / Department of Economics / Yang M. Chang / Concerns over the possible loss of government revenue resulting from tariff reductions under trade liberalization have triggered many developing countries to opt for a strategy of raising destination-based consumption taxes on tradable goods. The first essay analyzes the welfare effects of a coordinated tariff reduction and domestic tax reform when the objective of a reforming country is to keep its government revenue unchanged. Assuming imperfect competition in an import-competing industry, we find that revenue-neutral reform involving tariff reduction and an increase in domestic tax rate may reduce domestic welfare under plausible assumptions. It also discusses the scenario in which the reforming country's objective is to keep domestic profit (or production) unchanged. We further identify the conditions under which a profit-neutral tariff and tax reform may be welfare-improving or welfare-deteriorating. The second essay uses a reciprocal-dumping model to examine the welfare effects of the Byrd Amendment (i.e., the Continued Dumping and Subsidy Offset Act, or CDSOA). It analyzes the differences in optimal tariffs set by the home and foreign governments when the home (i.e., the U.S.) government redistributes anti-dumping duties to its domestic firm under the new trade law, as compared to the traditional antidumping policy under which these duties are government revenues. We derive conditions under which the CDSOA may raise or lower the price of an import-competing good in the U.S. market. The results show that the CDSOA is an instrument of protectionism and strictly improves the home country welfare when markets are less competitive than in Cournot equilibrium. We find that under the same market characteristics, the new trade law strictly reduces foreign country welfare. The CDSOA's welfare effect is shown to be ambiguous, however, when markets are more competitive than Cournot. The third essay modifies the model presented in Essay 2 to allow for the scenario in which the foreign country strategically responds to the home country's CDSOA law by adopting similar trade law. The results show that the foreign country is able to enhance its national welfare when the import-competing markets are less competitive than in the Cournot equilibrium. We also discuss whether it is welfare-improving for the U.S. to voluntarily repeal the Byrd Amendment and restore the traditional antidumping policy, considering that, otherwise, its trading partner may also adopt the CDSOA law. We find that it is still in the best interest to the U.S. not to revoke the Byrd Amendment when markets are less competitive than Cournot. When markets are more competitive than Cournot, however, repealing the Amendment may turn out to be socially welfare-improving.
