abstract: Tres Tangos para Duo de Contrabajos (Three Tangos for Double Bass Duet) is a three-movement set written by Andrés Martín and commissioned by Darren Cueva specifically for this document and accompanying performance project. This piece blends tango with Western art music in a style often referred to as “nuevo tango” (new tango) which was popularized by Astor Piazzolla. This research paper will serve as a performance aid for those wishing to present tango idioms on the double bass in addition to a more detailed guide to performing Tres Tangos by Martín. To give context to performers, this survey begins with a brief history of the tango and the life and stylistic developments of Astor Piazzolla. Various music and dance styles that contributed to early tango include, milonga, habanera, and tango andalúz. The resulting tango was popularized as a music and dance style in the early twentieth century. Astor Piazzolla brought the tango to the concert hall after studying composition with acclaimed professor Nadia Boulanger. His new tango style merged traditional tango, classical composition, and jazz music, which he was exposed to after his family moved from Argentina to New York. Tres Tangos was modeled after the style of Piazzolla. Characteristic articulation and improvised techniques are a fundamental aspect of the tango sound; a successful performance will depend on the musician’s ability to create these sounds. A detailed description of the most common elements is provided as well as suggestions for creating them on the double bass. Finally, I have compiled a specific performance guide for Tres Tangos. This guide includes rhythmic, articulation, fingering, and notational considerations, to assist in the performance of this piece. / Dissertation/Thesis / Doctoral Dissertation Music 2018

abstract: The study and performance of J.S. Bach’s music has long been essential for every string musician. A transcription of the Flute Partita in A minor, BWV 1013, is an excellent addition to the double bass repertoire. This paper includes a performance guide that discusses the technical and musical considerations of each movement, and a new transcription for double bass. Chapter 1 introduces the goals of the paper. Chapter 2 is an overview of the transcription that covers the reasoning behind the bowings, fingerings, note alterations, ornamentation, articulation, and interpretation included in the transcription. Chapters 3 through 6 discuss these technical and musical elements in the context of each movement of the Partita. There are two other transcriptions of this piece for double bass, both of which take a different approach to transcribing the music of Bach. The transcription includes two different versions of the Partita: a version with bowings and note alterations, and a second version that also includes fingering suggestions. The bowings are based on Bach’s manuscript of the Violin Partitas in order to accurately recreate bowings that Bach would have written. The suggested fingerings serve as guidance for bassists who study this piece and are included separately to acknowledge that there are other fingering possibilities. / Dissertation/Thesis / Doctoral Dissertation Music 2018

Nesta retrospectiva procurou-se por informações sobre personagens, instrumentos e aspectos musicais que se relacionassem com o desenvolvimento da linha de baixo nestes dois gêneros. Na análise dos dados, foram definidas as formações instrumentais mais utilizadas e os instrumentos responsáveis pela execução do baixo, bem como suas origens e a forma de tocá-los. Na segunda parte desta pesquisa, foi realizada a categorização e análise musical das linhas de baixo das músicas transcritas do período. Como resultado, foram definidos padrões de acompanhamento, formas de estruturação e feito um levantamento dos instrumentos mais utilizados. Através da comparação das análises, foi possível apontar algumas transformações ocorridas nas mesmas, com ênfase particular no período que o maxixe se transforma em samba / Abstract: This work makes a retrospective analysis of the maxixe and the samba, from 1870 to 1940, from the historical and musicological point. In this retrospective, information concerning people, instruments and other musical aspects related to the bass line development, in these two styles of music, was searched. In the analysis, the main group formations, the instruments used in the bass line performance, its origins and technique were defined. In the second part of this research a categorization and musical analysis of transcribed bass lines from the period were made. As a result, common comping patterns, structural forms and a survey of the most used instruments were defined. By comparison of the analysis, the main changes that occurred in the bass lines were noted with a particular emphasis in the period that the maxixe turned out to samba / Mestrado / Mestre em Música

A large sportfishery that targets both smallmouth (Labeobarbus aeneus) and largemouth (Labeobarbus kimberleyensis) yellowfish exists in South Africa. Both species have high conservation priority, and no assessments documenting the effect of angling on L. aeneus and L. kimberleyensis have been undertaken. The overall aim of this study was to provide an assessment of the impact of angling on L. aeneus and L. kimberleyensis. The specific objectives of this study were to characterise the sectors utilising Lake Gariep, document catch, effort and total catch for the fishery as well as the locality specific biology of L. aeneus and L. kimberleyensis. The study was undertaken on Lake Gariep, South Africa's largest impoundment, situated on the Orange River system in central South Africa. Subsistence fishers were the dominant user group, constituting 60 % of the fishery, the remainder constituted recreational anglers. Angler catches were dominated by carp (Cyprinus carpio; 74 %), followed by mudfish (Labeo capensis; 13 %) and smallmouth yellowfish (8 %). Catches of largemouth yellowfish contributed < 0.5 % to the total catch. The relative abundance of species by weight differed by area (χ² test of independence: χ² = 182, df = 4, p ≤ 0.05). On any sampling day time fished was the best predictor for differences in probability of capture (PC) (Wald X²(1) = 7.169, p = 0.007). The probability of capturing L. aeneus differed significantly between month (Wald X²(5) = 20.690, p = 0.000) and region (Wald X²(3) = 46.755, p = 0.000). The single best predictor of differences in log abundance and non-zero CPUE was region (Factorial ANOVA p ≤ 0.05). Mean CPUE ranged from 0.21 ± 0.06 kg. man⁻¹.hr⁻¹ to 0.82 ± 0.11 kg. man⁻¹.hr⁻¹ in the OV region and 0.42 ± 0.10 kg. man⁻¹.hr⁻¹ to 1.17 ± 0.24 kg. man⁻¹.hr⁻¹ in the GD region. Angler effort was higher in OV than in GD and ranged from 17 ± 3 anglers/day to 45 ± 9 anglers/day and 6 ± 1 anglers/day to 41 ± 8 anglers/day, respectively. Total catch was higher in the GD 46.0 [95 % CI = 15:102.6] t. period⁻¹ than the OV region 40.0 [95 % CI = 13.9:89.6] t. period⁻¹. The total catch from the Lake Gariep fishery between March and December 2007 was estimated to be 86.0 [95 % CI = 40.4:154.8] t. period⁻¹. Age and growth was determined using whole otoliths. The growth of L. aeneus was best described by the von Bertalanffy growth model as Lt = 481.80 (1- e⁻°·²²⁽t⁺°·⁶¹⁾). Gonadal development for L. aeneus was seasonal, with the gonadosomatic index peaking in January, revealing a distinct spawning season. The length at 50 % maturity for female L. aeneus was attained at a fork length of 354.7 mm. Natural mortality (M) was estimated at 0.55 year⁻¹. The growth of L. kimberleyensis was described by the von Bertalanffy growth model as Lt = 763.22 (1- e⁻°·¹¹⁽t⁺°·⁶³⁾). Only 6 mature female and 15 mature male L. kimberleyensis were recorded during the study period. The smallest mature female was a 390 mm FL stage four female and the earliest recorded mature male was a 337 mm FL, ripe running male. Natural mortality (M) was estimated at 0.08 year⁻¹ for L. kimberleyensis. Per recruit analysis indicated that current fishing mortality reduces the L. aeneus spawner biomass by 7 %, which is considered negligible. Labeobarbus kimberleyensis forms an insignificant proportion of anglers catches and stock status is currently considered pristine.

Magíster en Economía Aplicada. Ingeniero Civil Industrial / La dinámica de los procesos de adopción de innovaciones financieras ha sido de interés durante los últimos años ya que cada vez aparecen nuevos instrumentos que buscan aportar alternativas de inversión o protección al mercado. El presente trabajo busca caracterizar, a través del modelo de Bass, el proceso de adopción de nuevas opciones financieras, cuando por primera vez una acción es elegible como subyacente de dichas opciones, y ver qué aspectos del subyacente pueden dar indicios sobre este comportamiento a futuro, buscando un grado de predictibilidad. Es así como se encuentra que tanto calls como puts son adoptadas en el mercado en forma similar, mientas que pasa el tiempo las puts se adoptan más rápido, pero las calls prometen llegar a mayores niveles de transacción y liquidez. Además, se encuentra que se llegará a mayor liquidez de nuevas opciones o que tendrán un crecimiento más rápido, vista desde el dollar volume, a través de stocks con mayores dollar volume tanto de largo plazo como corto plazo, aunque con mayor crecimiento de ésta en el corto plazo, y además con mayor volatilidad histórica. Mientras que sería conveniente evitar stocks con alto dollar volume y ratio bid-ask en el largo plazo, pero bajo en el corto plazo, y también tener presente las condiciones de tasas de interés para decisiones al margen de comprar el stock, ya que adquirir calls sería una buena alternativa, y los índices de ventas cortas dado que es posible recrear una a través de opciones. Agregando a lo anterior, se estudiaron los retornos de estas nuevas opciones, encontrando que hay diferencias importantes entre los retornos de opciones recién introducidas al mercado y aquellas que se tranzan desde al menos ya 3 años, mientras que tienen un mismo perfil de riesgo y que según la teoría deberían tener los mismos retornos, además se probó para distintos portafolios, lo que daría evidencia de que nuevas opciones recargan algún riesgo adicional en sus retornos.

Nicknamed "Mr. Bass Trombone" for his role as a prominent, trailblazing recording artist, George Roberts (b. 1928) has often been recognized as redefining the role of the bass trombone in popular music as well as setting new standards for technical refinement and expressive possibilities of the instrument. Through two interviews and a comparison between ten recorded performances by Roberts and corresponding lead sheets, I make observations about Roberts' performance techniques and illustrate various examples of those techniques. The document includes 35 pp. of interview transcriptions.

This thesis examines formal organization in ground-bass works. While it is true that many or even most works of the ground-bass repertoire are variation sets over a ground, there also exist many ground-bass works that are not in variation form. The primary goal of this thesis is to elucidate the various ways in which such non-variation formal organizations may be achieved. The first chapter of this work discusses the general properties of ground basses and various ways that individual phrases may be placed in relation to the statements of the ground. The second chapter considers phrases groupings, phrase rhythm, and the larger formal organizations that result. The third chapter concludes this study with complete analyses of Purcell’s “When I am laid in earth” from Dido and Aeneas and Delanade’s “Jerusalem, convertere ad dominum Deum tuum” from his setting of the Leçons de ténèbres.

Aquaculture is currently the fastest growing animal production sector. Because the aquaculture sector is growing at rapid rates, certain materials for feed, specifically marine protein sources, are becoming increasingly expensive and unsustainable. To counteract the reliance on fishmeal (FM) and other marine protein sources in the industry plant protein (PP), specifically soybean meal (SBM), has been investigated to replace FM as a protein source. Unfortunately, SBM when given in high quantities (greater than 30%) has been shown to negatively affect fish performance including retarded growth, intestinal inflammation, reduction of spawn quality, as well as dysbiosis in the gut microbiome, most likely due to presence of antinutritional factors such as saponins and tannins in SBM. The goal of this thesis was to investigate the effect of nutritional programming (NP) with SBM-based diet on gut microbiota in broodstock and progeny fish. Three feedings trials were conducted to test the efficacy of 3 approaches towards improving the use of PP in fish.The first trial (Chapter 2), tested the effect of NP on larval zebrafish (Danio rerio). NP is the theory of introducing an early nutritional stimulus to an animal that will ‘program’ the animal to better utilize the stimuli later in its adult life. The zebrafish were programmed in their larval stages, and the trial lasted for 65 days. There was a significant effect on growth performance for the programmed group (NP-PP) in terms of weight gains, as the NP-PP group grew better compared to the non-programmed group (NP-FM) and negative control (-control). There was no significant effect on the gut microbiome in terms of alpha or beta diversity, however, there were significant changes in the relative abundance (RA) of the gut microbiome throughout time in the NP-PP and the NP-FM groups. The findings of the study support that early NP of zebrafish with SBM improves growth performance on PP diet, but the gut microbiome does not seem to be a mechanism for NP.The second feeding trial (Chapter 3) focused on NP induced in the zebrafish broodstock with dietary SBM. For two weeks, the broodstock fish were fed with either a SBM diet or a FM diet so that gametogenesis occurred with either a FM or PP diet. This phase was called the ‘broodstock programming’ stage. The broodstock were then spawned, and the larval fish were separated into four different treatments: 1) SBM broodstock progeny, fed SBM for the entire trial (PPBS-PP) 2) SBM broodstock progeny fed FM the entire trial (PPBS-FM), 3) FM broodstock progeny fed FM the entire trial (+ control, FMBS-FM), and 4) FM broodstock progeny fed SBM the entire trial (- control, FMBS-PP). The PPBS-PP group achieved similar weight gains compared to all other treatments in terms of grams, but was numerically greater than the FMBS-PP treatment. There were no differences detected in gut microbiome alpha or beta diversity in any of the groups, however, there was significant change observed of certain bacterial phyla between the ‘programmed broodstock’, larval fish, and fish at the end of the trial, 48 days post hatch. Overall, this trial suggests that parental programming does not improve PP utilization in the progeny of zebrafish. It also appears that the gut microbiome is not a mechanism of parental programming. The third feeding trial (Chapter 4), was conducted on largemouth bass (Micropterus salmoides). This chapter had a similar experimental design as the first trial (Chapter 2), and larval largemouth bass were programmed with dietary SBM. This trial had an additional group added to it, which included a dietary saponin-programmed group. The study found that the NP with SBM diet or dietary saponin did not improve PP utilization and growth performance of largemouth bass in its pre-adult age. The study also found that the NP with SBM diet or dietary saponin did not have any effect on the largemouth bass gut microbiome, and there does not seem to be any gut microbiome modification associated with the NP in this fish species. Overall, NP can be used to improve dietary PP utilization but optimal timing and PP delivery method must be well assessed to ensure successful PP exposure and adaptation in different species. Nevertheless, the gut microbiome does not seem to be affected by NP and therefore is not considered the mechanism behind NP. Finally, studies on both zebrafish and largemouth bass presented major shifts in the gut microbiome as the fish aged. In addition, the core microbiomes of both species appeared to become more pronounced as the fish become adults. There seem to be an evolutionary tie between host and its gut microbiome. More studies, however, should further investigate this and the genetic effects on gut microbiota development and its heritability.

Copper exposures of 400 μg/L for 5,10 and 15 days resulted in no significant differences in antibody titers of largemouth bass, Micropterus salmoides injected with Aeromonas hydrophila compared to control-injected bass. Twenty days of exposure did significantly increase titers. The control group had significantly lower antibody titers than either control-injected or copper-exposed.

Thomas G. Everett's activities as a catalyst for bass trombone repertoire and scholarship are significant in the development of further research in the field, and in the development of new performance repertoire. An examination of Everett's life and musical influences precedes the detailing of his pursuits of new solo/chamber music for the bass trombone. A discussion of Everett's efforts in obtaining new performance repertoire by means of commission or request is followed by an examination of four pieces composed for Everett. The four pieces profiled are Sonata Breve by Walter Hartley, Prelude, Fugue, and Big Apple by Walter Ross, Everett Suite by Ulysses Kay, and 100 Bars for Tom Everett by András Szöllösy. Three of these four pieces, the Hartley, Ross, and Kay selections, are the repertoire for the performance recital portion of this research. Everett's contributions in the area of publication, including details of his Annotated Guide to Bass Trombone Literature are addressed as well as his role as founder of the International Trombone Association (ITA) and the implications of this organization's existence upon the growth of knowledge in the area of trombone pedagogy and performance. Two appendices account for the pieces in which Everett was involved in bringing to the repertoire. A third appendix is an annotated bibliography of Everett's trombone-related periodical publications.
