Sovereignty

description: Hopi traditional songs or taatawi are more than aesthetic objects; they are sound-based expressions of Hopi authority.  As I argue in this dissertation, creating, performing, circulating, and remembering taatawi are what we might call acts of sonic sovereignty: a mode of authority articulated within ongoing, sound-based networks that include Hopi people, plants, weather systems, land, and other living things within Hopi territories.
      I begin by exploring the generative process through which taatawi do their connective work, which includes long-term collaborations between yeeyewat (composers) and environmental actors that establish a collective vision of prosperity that is realized when these songs are performed.  Hopi composer Clark Tenakhongva’s taatawi performances during Grand Canyon National Park’s Centennial (a Hopi sacred space currently controlled by settler governments) exemplify the ways Hopi people are actively using taatawi to (re)assert Hopi relations to colonized territories.
      Because taatawi are closely tied to Hopi relations to one another and the land, and sometimes contain specialized forms of knowledge held closely by Hopi clans and ceremonial societies, their ownership and circulation remains of vital concern to Hopi people.  Laura Boulton’s recording of Hopi singers Dan Qötshongva, Thomas Bahnaqya and David Monongye in the Summer of 1940, and the travels of those recordings afterwards, show us the complex politics of Hopi song circulation in the early Twentieth Century up through the present, and how settler cultural and intellectual property laws provide only limited possibilities for indigenous groups seeking to bring their ancestors’ voices back under their control.  And even if tribes could reclaim taatawi under settler property laws, these laws require physical and conceptual transformations that effectively sever them from the networks of relations from which they were created.
      To better support Hopi sonic sovereignty going forward, I offer brief sketches for three potential interventions: (1) an indigenous works amendment to the United States Copyright Act; (2) the use of indigenized licensing frameworks to embed indigenous protocols into the governance and circulation of indigenous creative works both on and off indigenous lands; and (3) establishing a right to indigenous care, similar to Europe’s right to forget, whereby our ancestors’ voices can be subject to indigenous care rather than preserved anonymously and perpetually as archival objects.  My hope is that these will allow indigenous communities to better assert and maintain control over their modes of sonic sovereignty despite the increasing colonization of the sonic world by global intellectual property regimes.

description: In this paper a framework for app store optimization is proposed. The framework is based on two main areas: developer dependent elements and user dependent elements. Developer dependent elements are similar to factors in search engine optimization. User dependent elements are similar to activities in social media. The proposed framework is modelled after downloading sample data from two leading app stores: Google Play and Apple iTunes. Results show that developer dependent elements can be better optimized.

description: Matching methods are widely used for causal inference in observational studies. Among them, nearest neighbor matching is arguably the most popular. However, nearest neighbor matching does not generally yield an average treatment effect estimator that is $\sqrt{n}$-consistent (Abadie and Imbens, 2006). Are matching methods not $\sqrt{n}$-consistent in general? In this paper, we study a recent class of matching methods that use integer programming to directly target aggregate covariate balance as opposed to finding close neighbor matches. We show that under suitable conditions these methods can yield simple estimators that are $\sqrt{n}$-consistent and asymptotically optimal.

description: The Fording River Mine, operated by Fording Coal Limited is located in the Rocky Mountains of British Columbia at elevations ranging from 1650 to 2300 m. Research has been conducted at the mine site since 1969 to develop technology for restoring the forest resource and the critical wildlife habitat. Experiments have been conducted to determine the effect of seeding two species of legumes with the conifer species. The effect of an interseed delay of up to five years on various growth parameters of the conifers was assessed. The growth of the conifers was compared to height to age curves developed for natural regeneration on forest sites in the valley. Research has also been conducted to determine the optimal method of establishment of deciduous trees and shrubs which are critical for the development of ungulate winter range on steep, south aspect slopes. Innovative techniques utilizing various types of seedling protectors have been tested. A range of native trees and shrubs have been tested on various sites and lists of candidate species developed.

description: In order to understand how current environmental conditions affect farmer decision making the levels of grass and soil condition are examined in the decision on when to turn cattle out from winter housing to spring grazing on Irish dairy farms. Five years of satellite derived Normalised Difference Vegetation Index MODIS data, as a proxy for grass growth data, were used along with daily rainfall data and turn out dates from 199 dairy farms. Using GIS analysis conditions at the time of turn out were determined at the date and location of the event. A panel analysis shows that farmers respond to early growth but not immediately, gaining three and half days extra grazing for every week that grass growth is early. The inertia in decision making around a preferred date was shown by using the previous year’s turn out date in the model. We can accurately predict when turn out occurs with a RMSE of 10 days, compared to average on farm range of dates over the 2008-2012 period of 25 days.

description: We consider the random 2-satisfiability problem, in which each instance is a formula that is the conjunction of m clauses of the form (x or y), chosen uniformly at random from among all 2-clauses on n Boolean variables and their negations. As m and n tend to infinity in the ratio m/n --> alpha, the problem is known to have a phase transition at alpha_c = 1, below which the probability that the formula is satisfiable tends to one and above which it tends to zero. We determine the finite-size scaling about this transition, namely the scaling of the maximal window W(n,delta) = (alpha_-(n,delta),alpha_+(n,delta)) such that the probability of satisfiability is greater than 1-delta for alpha < alpha_- and is less than delta for alpha > alpha_+. We show that W(n,delta)=(1-Theta(n^{-1/3}),1+Theta(n^{-1/3})), where the constants implicit in Theta depend on delta. We also determine the rates at which the probability of satisfiability approaches one and zero at the boundaries of the window. Namely, for m=(1+epsilon)n, where epsilon may depend on n as long as |epsilon| is sufficiently small and |epsilon|*n^(1/3) is sufficiently large, we show that the probability of satisfiability decays like exp(-Theta(n*epsilon^3)) above the window, and goes to one like 1-Theta(1/(n*|epsilon|^3)) below the window. We prove these results by defining an order parameter for the transition and establishing its scaling behavior in n both inside and outside the window. Using this order parameter, we prove that the 2-SAT phase transition is continuous with an order parameter critical exponent of 1. We also determine the values of two other critical exponents, showing that the exponents of 2-SAT are identical to those of the random graph.

description: We calculate the radiative corrections of order O(alpha E_e/m_N) as next-to-leading order corrections in the large nucleon mass expansion to Sirlin's radiative corrections of order O(alpha/pi) to the neutron lifetime. The calculation is carried out within a quantum field theoretic model of strong low-energy pion--nucleon interactions described by the linear sigma-model (LsM) with chiral SU(2)xSU(2) symmetry and electroweak hadron-hadron, hadron-lepton and lepton-lepton interactions for the electron-lepton family with SU(2)_L x U(1)_Y symmetry of the Standard Electroweak Model (SEM). Such a quantum field theoretic model is some kind a hadronized version of the Standard Model (SM). From a gauge invariant set of the Feynman diagrams with one-photon exchanges we reproduce Sirlin's radiative corrections of order O(alpha/pi), calculated to leading order in the large nucleon mass expansion, and calculate next-to-leading corrections of order O(alpha E_e/m_N). This confirms Sirlin's confidence level of the radiative corrections O(alpha E_e/m_N). The contributions of the LsM are taken in the limit of the infinite mass of the scalar isoscalar sigma-meson. In such a limit the LsM reproduces the results of the current algebra (Weinberg, Phys. Rev. Lett. {\bf 18}, 188 (1967)) in the form of effective chiral Lagrangians of pion-nucleon interactions with non--linear realization of chiral SU(2)xSU(2) symmetry. In such a limit the L$σ$M is also equivalent to Gasser-Leutwyler's chiral quantum field theory or chiral perturbation theory (ChPT) with chiral SU(2)xSU(2)symmetry and the exponential parametrization of a pion-field (Ecker, Prog. Part. Nucl. Phys. {\bf 35}, 1 (1995)).

description: We consider a set of operators hat{x}=(hat{x}_1,..., hat{x}_N) with diagonal representatives P(n) in the space of generalized coherent states |n>; hat{x}=int dn P(n) |n>_L over polygonal paths with L vertices {n_1...L}. The distribution of the path centroid bar{P}=(1/L) sum_{i=1}^{L}P(n_i) tends to the Wigner function W(x), the joint distribution for the operators: W(x)=lim_{L->infinity} _{L}. This result is proved in the case where the Hamiltonian commutes with hat{x}. The Wigner function is non-positive if the dominant paths with path centroid in a certain region have Berry phases close to odd multiples of pi. For finite L the path centroid distribution is a Wigner function convolved with a Gaussian of variance inversely proportional to L. The results are illustrated by numerical calculations of the spin Wigner function from SU(2) coherent states. The relevance to the quantum Monte Carlo sign problem is also discussed.

description: The purpose of this study is to propose a model that includes student dynamics with the item position effect and student motivation as a test-related psychological factor. In addition, missing data mechanisms were incorporated into models to mimic the actual scene when taking tests. As a prerequisite of the study, the existence of item position effects was identified. Following the first study, SEM models that included student motivation with the item position effect were evaluated, and different missing dataset types were fitted to the SEM models. All analyses used TIMSS 2015 grade 8 mathematics data from the U.S. as exemplary large-scale assessment data. Thus, a significant item position effect was identified on mathematics achievements, accounting for the relevant covariates of student background, socioeconomic status, and psychological variables; the full model with both student motivation and the item position effect was revealed as the best with complete data; the MNAR missingness type was found to have meaningful information that must be considered in test administration. This research should complement well-developed item position effect studies by focusing on modeling the effect with personal factors that show individual differences, thereby avoiding biased estimates in large-scale assessments.

description: This dissertation is a qualitative case study exploring the understandings, beliefs, and practices of Youth Spoken Word Poetry (YSW) educators who work within the field of Hip Hop-Based Education (HHBE) and have grown from youth participants to adult professionals within an international YSW Network. This study examines how current YSW practitioners describe and understand their work, along with the multiple literacy practices they utilize related to spirituality and race. This study is framed by a sociocultural lens of education, includes a blend of qualitative research methods related to narrative approaches, and is inspired by literature grounded in Hip Hop-Based Education; Race and Education; and Spirituality and Education. It is a hope of this study that the findings lead to a more nuanced understanding of how HHBE functions within the landscape of education and impact how we approach HHBE moving forward.
      Major findings revealed that the participants describe themselves as racialized and spiritual beings in implicit and explicit ways. YSW participants in this study described the field of YSW as grounded in African American lineages and acknowledged that the field currently functions as pluralistic and multicultural. YSW participants describe spirituality as personal, collective, and transcendent experiences. Though participants defined spirituality differently, they described it as something that is present, naming it as an important factor to be considered when examining YSW practice. Core literacy practices participants engaged with and enacted within the YSW community related to race and spirituality included acknowledging their voice as something that was expressed individually, collectively, and universally and across time (past, present, and future). These findings highlight the value of communities that support: (1) Reflection, or honoring individual identities; (2) Refraction, or honoring Communities of Practice that shape our paths; and (3) Dispersion, or the use of stories to support dreaming, sharing, and revolutionizing the world as we know it.

It is shown that the trivial Schwarzschild Anti de Sitter becomes unstable in some of these situations, and the possible relevance of this fact for the ADS/CFT conjecture is pointed out.

description: Traces of three Anglo-Saxon inhumation burials were found during a rescue excavation in 1985 at Stafford Road, Brighton. One largely in situ male burial contained a knife and buckle of 7th-century date, while another male grave, badly disturbed by builders, appears to be of the 6th century. Skeletal evidence from this burial shows that the man died from a severe head wound, probably inflicted by a sword blow, but had survived a previous traumatic head wound which had partially healed. Two button brooches and other objects indicate that the third burial was a woman's grave of the 6th century.

description: We examine the achronal averaged null energy condition~(ANEC) for a class of conformal field theories~(CFT) at strong coupling in curved spacetime. By applying the AdS/CFT duality, we find holographic models which violate the achronal ANEC for $3+1$ and $4+1$-dimensional boundary theories. In our model, the bulk spacetime is an asymptotically AdS vacuum bubble solution with neither causality violation nor singularities. The conformal boundary of our bubble solution is asymptotically flat and is causally proper in the sense that a "fastest null geodesics" connecting any two points on the boundary must lie entirely on the boundary. We show that conversely, if the spacetime fails to have this causally proper nature, then there must be a naked singularity in the bulk.

description: The amount of light an exoplanet reflects and emits towards an observer waxes and wanes as the planet orbits through its phases. The amplitude and profile of reflection phase curves constrain the albedo of planetary surfaces and atmospheres, while the thermal amplitude and profile reveal temperature distributions and heat transport efficiencies, all providing valuable insight into the nature of exoplanet surfaces and atmospheres. In this dissertation I highlight the usefulness of utilizing full orbital phase curves in addition to occultation measurements, which provides a higher sensitivity to planetary photons at the expense of a more challenging data reduction. In the first few chapters of this dissertation, I introduce a novel non-parametric algorithm to produce clean, robust exoplanet phase curves, and apply it to separate ensembles of 115 Neptunian and 50 Terran exoplanets observed by the Kepler satellite to measure an upper limit on the average albedo of Kepler’s Neptunian planets, and make the first constraint on the average albedo of Terran worlds. In the fourth chapter, I present the full orbital phase curve and occultation of the ultra-hot Jupiter WASP-100b observed by the Transiting Exoplanet Survey Satellite (TESS), and with the use of Bayesian methods, present the first measurement of a phase shift of the thermal maximum among the phase curves observed by TESS, the degree of which challenges the predicted efficiency of heat transport in the atmospheres of ultra-hot Jupiters. In the final chapter, I present an example of how the NASA ROCKE-3D general circulation model can be used to explore the physical mechanisms that influence the habitability of terrestrial exoplanets, and then show how I generated phase curves from the 3-dimensional models to study the signals produced by simulated TRAPPIST-1 habitable-zone worlds. The work in this dissertation contributes valuable new information to the astronomical literature and provides avenues for further research on the nature of short-period exoplanets.

description: Most flying animals produce aerodynamic forces by flapping their wings back and forth with a complex wingbeat pattern. The fluid dynamics that underlies this motion has been divided into separate aerodynamic mechanisms of which rotational lift, that results from fast wing pitch rotations, is particularly important for flight control and manoeuvrability. This rotational force mechanism has been modelled using Kutta–Joukowski theory, which combines the forward stroke motion of the wing with the fast pitch motion to compute forces. Recent studies, however, suggest that hovering insects can produce rotational forces at stroke reversal, without a forward motion of the wing. We have conducted a broad numerical parametric study over a range of wing morphologies and wing kinematics to show that rotational force production depends on two mechanisms: (i) conventional Kutta–Joukowski-based rotational forces, and (ii) a rotational force mechanism that enables insects with an offset of the pitch-axis relative to the wing's chordwise symmetry axis to generate rotational forces in the absence of forward wing motion. Because flying animals produce control actions frequently near stroke reversal, this pitch-axis-offset dependent aerodynamic mechanism may be particularly important for understanding control and manoeuvrability in natural flyers.
Jacopo Tintoretto in Process: The Making of a Venetian Master, 1540-1560

description: The Last Judgment and the Making of the Golden Calf in the Church of the Madonna dell'Orto in Venice are two of the tallest canvas paintings ever created, each measuring some 14.5 m (47.6 feet) high. At this scale these pictures are clearly statements, made by an artist accustomed to confrontation. Jacopo Tintoretto (c.1518-1594) executed the pair of paintings around 1558-60 for the choir of his neighborhood church, in a commission that he apparently initiated himself, asking payment only for materials. The novelty of their monumentality and indeed their preeminence within Tintoretto's oeuvre were noted by early biographers. The paintings have received little attention in modern scholarship, however, which has tended to prioritize instead as his greatest accomplishments the Miracle of the Slave (1548) - Tintoretto's first picture in a series for the Scuola Grande di San Marco - and the dozens of canvases for the Scuola Grande di San Rocco (1564-88). Moreover, the initial paintings for both of these scuola cycles have been regarded in the literature as among the artist's most pivotal moments, overshadowing his work in the intervening decade of the 1550s, particularly the Last Judgment and the Making of the Golden Calf  and a group of important paintings leading up to them.

      This dissertation argues that, far from being outliers in Tintoretto's oeuvre, the choir paintings for the Madonna dell'Orto - in their scale, technique, iconography, and personal meaning - should be seen as key steps in the artist's personal development and public achievement. Moreover, they represent a critical moment of arrival, summing up, in a grand statement of self-promotion, his work of the 1540s and 1550s. These two paintings must also be viewed as Tintoretto's response to the adversity he endured in the first half of his career. Spurred by his own ambition, faced with the hostility of artistic rivals both old and new, and inspired by an enduring ambition to challenge Michelangelo, Tintoretto initiated the two gigantic choir paintings about the year 1558 to revive a career that had flagged since his triumphant debut with the Miracle of the Slave a decade earlier.
      An examination of Tintoretto's biography, the intentions behind and reception of individual pictures, his stylistic and technical development, the influences of critics and fellow artists, together provide for the first time a detailed analysis of the painter's evolution  in the period around the Miracle of the Slave and the dozen years that followed. This is the stage of his career that prepared Tintoretto to take on the challenges of the Scuola Grande di San Rocco and the massive commissions for the Palazzo Ducale. The turbulent decades of the 1540s and 1550s show an artist in process, on the verge of becoming the master who would dominate painting in Venice in the second half of the sixteenth century.
Universal algebraic relaxation of fronts propagating into an unstable state

description: We analyze ``pulled'' or ``linearly marginally stable'' fronts propagating into unstable states. While ``pushed'' fronts into meta- and unstable states relax exponentially, pulled fronts relax algebraically, and simultaneously the standard derivation of effective interface equations breaks down. We calculate all universal relaxation terms of uniformly translating pulled fronts. The leading $1/t$ and $1/t^{3/2}$ corrections to the velocity are determined by the dispersion relation of the linearized equation only. Our analysis sheds new light on the propagation mechanism of pulled fronts.

description: This dissertation chronicles the plight of the lower status professional group member and their attempts to get recognition by using insider language or jargon. Specifically, it explores jargon within the broader context of status signaling, language, and hierarchical relationships. It seeks to understand how language is used as a way to both gain and infer status. Chapter 1 accomplishes two goals. First, it discusses features of human status systems and status signaling processes. Second, it defines jargon and identifies its functions. In doing so, I incorporate linguistic and social psychological theories to argue that jargon is a marker of status or a status symbol. I differentiate jargon from related linguistic concepts of slang and technical language, and I differentiate jargon from other status signals due to the social costs incurred through its use. Chapter 2 focuses on one social motivation for using jargon, arguing that status threat increases jargon use. It proposes that because jargon is a status marker, it is strategically used by those experiencing low status. Across 10 studies, using both archival and experimental methods, I link low status to jargon use because lower status motivates impression management goals. Chapter 3 explores how the effects of both local and global sources of status threat independently contribute to compensatory and performative jargon use. It replicates findings from chapter 2 while highlighting how multiple sources of status threat combine to provoke status signaling behaviors. Chapter 4 explores the consequences of jargon use, drawing on prior theory in linguistics and social psychology. It begins by showing that high jargon use imposes a cognitive cost upon an audience, which then may then disengage from the speaker’s message as a result. It then shows how high jargon may increase audience appraisals of speaker competence but reduce interpersonal closeness and ratings of warmth. The chapter argues that that high jargon use is particularly interpersonally costly for low-status speakers because they are seen as annoyingly reaching above their station. I also show that extremely low levels of jargon, i.e., flamboyantly colloquial language, also hurt evaluations of a speaker. These results suggest a goldilocks phenomenon, whereby there is a ‘just right” amount of jargon necessary to optimize audience evaluations across warmth, competence, and status. The final chapter five of this dissertation highlights a number of interesting patterns and unanswered questions, paving the way for further studies and lines of inquiry. Overall this dissertation takes a deep dive into the antecedents and consequences of hyperbolic circumluoquationaness, sesquipedalianistic poeanoisms, and professional jive talk, to expand our understanding of how language functions in performing, negotiating, and affecting social relationships with others in everyday life.
Lorentzian regularization and the problem of point-like particles in general relativity

description: The two purposes of the paper are (1) to present a regularization of the self-field of point-like particles, based on Hadamard's concept of ``partie finie'', that permits in principle to maintain the Lorentz covariance of a relativistic field theory, (2) to use this regularization for defining a model of stress-energy tensor that describes point-particles in post-Newtonian expansions (e.g. 3PN) of general relativity. We consider specifically the case of a system of two point-particles. We first perform a Lorentz transformation of the system's variables which carries one of the particles to its rest frame, next implement the Hadamard regularization within that frame, and finally come back to the original variables with the help of the inverse Lorentz transformation. The Lorentzian regularization is defined in this way up to any order in the relativistic parameter 1/c^2. Following a previous work of ours, we then construct the delta-pseudo-functions associated with this regularization. Using an action principle, we derive the stress-energy tensor, made of delta-pseudo-functions, of point-like particles. The equations of motion take the same form as the geodesic equations of test particles on a fixed background, but the role of the background is now played by the regularized metric.

description: The dynamical structure factor (DSF) of strongly coupled ions in dense plasmas with partially and strongly degenerate electrons is investigated. The main focus is on the impact of electronic correlations (non-ideality) on the ionic DSF. The latter is computed by carrying out molecular dynamics (MD) simulations with a screened ion-ion interaction potential. The electronic screening is taken into account by invoking the Singwi-Tosi-Land-Sjölander approximation, and compared to the MD simulation data obtained considering the electronic screening in the random phase approximation and using the Yukawa potential. %This allows us to gain insight into the impact of the electronic non-ideality on the ionic DSF. We find that electronic correlations lead to lower values of the ion-acoustic mode frequencies and to an extension of the applicability limit with respect to the wave-number of a hydrodynamic description. Moreover, we show that even in the limit of weak electronic coupling, electronic correlations have a non-negligible impact on the ionic longitudinal sound speed. Additionally, the applicability of the Yukawa potential with an adjustable screening parameter is discussed, which will be of interest, e.g., for the interpretation of experimental results for the ionic DSF of dense plasmas.

Jazz and Radio in the United States: Mediation, Genre, and Patronage

description: This dissertation is a study of jazz on American radio. The dissertation's meta-subjects are mediation, classification, and patronage in the presentation of music via distribution channels capable of reaching widespread audiences. The dissertation also addresses questions of race in the representation of jazz on radio. A central claim of the dissertation is that a given direction in jazz radio programming reflects the ideological, aesthetic, and political imperatives of a given broadcasting entity. I further argue that this ideological deployment of jazz can appear as conservative or progressive programming philosophies, and that these tendencies reflect discursive struggles over the identity of jazz. The first chapter, "Jazz on Noncommercial Radio," describes in some detail the current (circa 2013) taxonomy of American jazz radio.  The remaining chapters are case studies of different aspects of jazz radio in the United States. Chapter 2, "Jazz is on the Left End of the Dial," presents considerable detail to the way the music is positioned on specific noncommercial stations. Chapter 3, "Duke Ellington and Radio," uses Ellington's multifaceted radio career (1925-1953) as radio bandleader, radio celebrity, and celebrity DJ to examine the medium's shifting relationship with jazz and black American creative ambition. Chapter 4, "Jazz with Ads," uses the mid-1960s to mid-1970s period, in which commercial all-jazz radio had a limited run, as a prism to examine the interwoven roles of genre, format, and commerce in the presentation of jazz on the air.
