The alteration of the global environment by human activities is so widespread that scientists argue we've entered a new geologic epoch known as the Anthropocene. This dissertation examines the impact of human activities on biogeochemical cycling at the land-sea interface. I focus primarily on the role of land use/land cover (LULC) and coastal nutrient enrichment on silicon (Si) cycling in New England rivers and salt marshes. On land, Si is taken up by vegetation, improving plant fitness and protecting plants from a variety of environmental stressors. In aquatic systems, diatoms, the dominant type of phytoplankton in coastal temperate waters, require Si to survive. My research demonstrates that LULC is an important driver of Si export to coastal systems, accounting for 40-70% of the variability of riverine fluxes. Developed watersheds export significantly (p=0.03) more Si than their forested counterparts, which I hypothesize is due to less vegetated cover, a known Si sink, in developed watersheds. Building on this, I calculated the amount of Si fixed by land plants globally (84 Tmol yr-1) and the percent (55%) of global terrestrial net primary production that can be attributed to active Si-accumulating organisms. Next, I created the first complete salt marsh Si budget by quantifying tidal creek fluxes and net Si accumulation in a relatively undisturbed low-nutrient salt marsh. Further, comparing this Si accumulation to that of a high-nutrient marsh revealed that the high-nutrient marsh contained significantly (p<0.05) more Si within the sediments, roots, and porewater. Combining my original data from six New England salt marshes with published values, I quantify the mode of Si accumulation (rejective, passive, or active) by Spartina grasses and the environmental controls on such accumulation. Finally, using radionuclide tracers 137Cs and 210Pb, I calculated vertical accretion rates of five salt marshes and compared these values to historical measurements. I found that accretion rates have slowed and this deceleration is driven, in part, by a decrease in organic matter accumulation. Together, this dissertation improves our knowledge of Si cycling in terrestrial and aquatic ecosystems, and identifies previously unrecognized ways in which humans are perturbing biogeochemical cycles at the land-sea interface.

Thesis (M.A.)--Boston University / The purpose ot this study was to analyse the four-year undergraduate mechanical-engineering curricula in the engineering schools in New England and New York State, with a view to discovering clues to possible improvement of a similar curriculum in Bradford Durfee Technical Institute in Fall River, Massachusetts.

Thesis (Ed.D.)--Boston University. / The purpose of this study was to determine the competencies of beginning elementary classroom teachers in music theozy and singing. The areas of strength and weakness in music theory and singing were ascertained for reference by teacher-training institutions and public schools trying to meet the needs of the classroom teacher in music.

This thesis presents Bayesian geoacoustic inversion of seabed reflection-coefficient data as part of the U.S. Office of Naval Research Seabed Characterization Experiment 2017 at the New England Mud Patch. First, a linearized, ray-based Bayesian inversion of acoustic arrival times is carried out for high-precision estimation of experiment geometry and uncertainties, representing an important first step to inferring seabed properties using geoacoustic inversion methods such as reflection inversion. The high-precision estimates for source-receiver ranges, source depths, receiver depths, and water depths at reflection points along the survey track are used to calculate grazing angles, with angle uncertainties computed using Monte Carlo methods. The experiment geometry uncertainties are obtained using analytic linearized estimates, and verified with nonlinear analysis. Second, a trans-dimensional (trans-D) Bayesian inversion of reflection-coefficient data is carried out for geoacoustic parameters and uncertainties of fine-grained/cohesive sediments. The trans-D inversion samples probabilistically over an unknown number of seabed interfaces and the parameters of a zeroth- or first-order autoregressive error model. The numerical method of parallel tempering reversible jump Markov-chain Monte Carlo sampling is employed. Spherical-wave reflection coefficient modelling is applied using plane-wave decomposition in the Sommerfeld integral. The inversion provides marginal posterior probability profiles for Buckingham's viscous grain-shearing parameters: porosity, grain-to-grain compressional modulus, material exponent, and compressional viscoelastic time constant as a function of depth in the sediment. These parameters are used to compute dispersion relationships for each layer in the model, providing marginal posterior probability profiles for compressional-wave velocity and attenuation at different frequencies, as well as density. The geoacoustic inversion results are compared to independent measurements of sediment properties. / Graduate

Accordingly, we highlight aspects that justify the inclusion of the work as a historical novel, especially based on the reading of The Historical Novel (1936-37) written by Georg Luk?cs. The diversity of voices and social interrelationships that come out of the main characters of the plot of the novel, as well as their contextual buildings, constituted as important traces to understanding the novel as being of historical value. During our study, we found out that it is in the plots of the novels that the characters reflect, at the same time, the specific conditions of their singularities, the general trends of the historical process and the social conditions from which they arise. We also could see that it is in their singularities that lie special tendencies of human beings. Our references to this study came from scholars as Howard (1964), Bakhtin (1998), Eagleton (2006), Todorov (2009), Zabel (1947), Sellers (1985), Cunlife (1986), Candido (1993) and Schwarz (1981) / O objetivo deste trabalho ? analisar a obra do escritor americano Nathaniel Hawthorne (1804 1864), A Letra Escarlate (1850), ? luz das contribui??es da Literatura e da Hist?ria do povo americano no contexto da Nova Inglaterra dos primeiros s?culos de sua exist?ncia at? o per?odo em que viveu o seu autor. Nesse sentido, buscaremos evidenciar aspectos que justificam a inser??o da obra como um romance hist?rico, especialmente a partir da leitura de O Romance Hist?rico (1936-37) de Georg Luk?cs. A diversidade das vozes sociais e os inter-relacionamentos que se depreenderam dos personagens principais do enredo do romance, assim como as suas constru??es contextuais, se constitu?ram como elementos importantes para a compreens?o do romance como sendo de valor Hist?rico. Durante o nosso estudo, verificamos que ? nos enredos dos romances que as personagens refletem, ao mesmo tempo, as condi??es espec?ficas de suas singularidades, as tend?ncias gerais do processo hist?rico e as condi??es sociais das quais eles surgem. Pudemos verificar tamb?m que ? em suas singularidades que se concentram tend?ncias pr?prias do ser humano. Para fundamentar este estudo buscamos refer?ncias em te?ricos da literatura mundial como Howard (1964), Bakhtin (1998), Eagleton (2006), Todorov (2009), em historiadores como Zabel (1947), Sellers (1985) e Cunlife (1986), bem como nas repercuss?es da obra no Brasil, notadamente a partir de leituras realizadas por Candido (1993) e Schwarz (1981)

abstract: "The Wicked Man's Portion" uses crime writing as a means to measure modernity in early America. Crime writing does things all too familiarly "modern"; it imagines audiences in need of moral instruction, citizens questioning the decisions of those in power, and men and women seeking reassurance that their community was safe, just, and moral. Crime writing pries open the dialectic between the expectations of authority and individuals' experiences. What emerges is the concept of a moral citizen, a self-reliant individual sharing responsibility for a well-ordered community. The first chapter examines typological interpretations of scripture in execution sermons revealing the interrelation between religion and law. Chapters two and three focus on the interaction between criminal law and beliefs in the supernatural; chapter two looks at supernatural crimes and forensic methods, such as those surrounding witch trials, and chapter three examines arguments for capital punishment that hinged upon divine involvement in human affairs. The fourth chapter discusses gallows publications' functions in the public sphere and contributions to inchoate democracy. The final chapter asks how equity defined punishment in economic terms. This chapter pays particular attention variations of punishment determined by race, class, and gender. / Dissertation/Thesis / Ph.D. English 2013
