Ep. #183 - Solar Power, Solar Justice (feat. Dustin Mulvaney)
No full textThis recording and transcript form part of a collection of podcasts conducted by the Cultures of Energy at Rice University. Cultures of Energy brings writers, artists and scholars together to talk, think and feel their way into the Anthropocene. We cover serious issues like climate change, species extinction and energy transition. But we also try to confront seemingly huge and insurmountable problems with insight, creativity and laughter.Cymene and Dominic cover the stress (and joy!) of center directorships and sandwich-making on this week’s podcast. Then (13:53) Dustin Mulvaney (http://www.dustinmulvaney.com) visits the pod to tell us all the things we need to know about solar energy but were afraid to ask. He’s the author of the excellent new book, Solar Power: Innovation, Sustainability and Environmental Justice(U California Press, 2019). We start by talking about whether it’s possible to make a solar power revolution both rapid and just. That gets us to the toxic externalities of solar cell manufacture and his work with the Silicon Valley Toxics Coalition (http://svtc.org) to create a Solar Scorecard system that helps pressure manufacturers to clean up their production processes. Dustin breaks down for us the environmental advantages and disadvantages of both photovoltaic (PV) and concentrated solar (CSP) systems and then we turn to what he calls the “Green Civil War” brewing between animal rights activists and renewable energy activists over land use changes especially in the American Southwest. In closing we discuss whether a radically decentralized energy ecology could help advance environmental justice goals and what lessons should be learned from Obama era ARRA solar investments in terms of improving energy justice in the future
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.

High-resolution trace element geochemistry and sequence stratigraphy of the Middle-Late Devonian (Givetian-Frasnian) Frasnes crisis
No full textThe Middle–Late Devonian (Givetian–Frasnian) ‘Frasnes’ event is marked by a second order mass extinction approximately coeval with the deposition of black shale on a global scale and the ‘falsiovalis’ positive δ13C isotope excursion. These characteristics are also hallmarks of extensively studied mass extinction events such as the Late Devonian Kellwasser (Frasnian-Famennian) and the end-Devonian Hangenberg crises. However, the relative timing of black shale intervals, eustatic sea-level fluctuations, and the carbon isotope excursion is unknown, and any possible causative relationships cannot be determined. This research provides a high-resolution integrated geochemical dataset to evaluate the paleoenvironmental condition of the rocks deposited during the Frasnes interval in central Nevada and compares those results to the better understood Kellwasser and Hangenberg events. Geochemical data from the Frasnes event is tied to lithostratigraphic sections and used to build a sequence stratigraphic framework from which eustatic changes are identified and linked directly to elemental abundance data. These data, in conjunction with new biostratigraphic and carbon isotope data collected from the same samples, places these events within a chronostratigraphic framework and helps to further our understanding of this significant Earth history event.Restricted until 06/2023.

The Malleability of the Past: "Íslendingabók" as Narrative History
No full text"Íslendingabók" (Book of Icelanders) is the earliest surviving history of Iceland, written by the priest Ari Þorgilsson sometime between 1122 and 1133. Despite spanning the period from the Settlement in the ninth century to 1118, the work is concise, which suggests that a specific selection of information was made by the author during the composition process. This hypothesis is supported by the quality of the information conveyed, which seems to favour Ari himself and his patrons, and by Ari’s omission of material that would compromise his view, evidence of which is nevertheless present in other sources.
This article explores "Íslendingabók" as a careful reconstruction of the Icelandic past, thus as narrative history; the focus will be on the strategies and aims that lay behind the author’s project, not least on the ideological foundations that shaped Ari’s views. This approach will allow for a better appreciation of the text and its production context, as compared to the influential but often uncritical methods used to study the work that flourished during the late nineteenth and early twentieth centuries and which still reverberate today, within both scholarly discussions of the work and popular contemporary attitudes in Iceland towards the country’s medieval history and culture
Toward a Credible Pacifism: Violence and the Possibilities of Politics
No full textAdvocates of pacifism usually stake their position on the moral superiority of nonviolence and have generally been reluctant or unwilling to concede that violence can be an effective means of conducting politics. In this compelling new work, which draws its examples from both everyday experience and the history of Western political thought, author Dustin Ells Howes presents a challenging argument that violence can be an effective and even just form of power in politics. Contrary to its proponents, however, Howes argues that violence is no more reliable than any other means of exercising power. Because of this there is almost always a more responsible alternative. He distinguishes between violent and nonviolent power and demonstrates how the latter can confront physical violence and counter its claims. This brand of pacifism gives up claims to moral superiority but recuperates a political ethic that encourages thoughtfulness about suffering and taking responsibility for our actions.https://repository.lsu.edu/facultybooks/1404/thumbnail.jp
Search for single production of vector-like quarks decaying into a W-boson and a b-quark at 13 TeV
No full textA search for singly produced vector-like quarks decaying into Wb with one lepton and jets final states using data collected by ATLAS at 13 TeV in 2015 will be presented. The search employs a high-transverse momentum b-tagged jet, a forward jet originating from the initial-state quark and no other jet activity in the central region of the detector. No significant excess over Standard Model backgrounds is observed and upper limits on the cross-section times branching ratio and couplings are set
Search for Single Production of Vector-like Quarks Decaying into Wb in pp Collisions at sqrt(s)=13 TeV with the ATLAS Detector
No full textIn dieser Dissertation wird die Suche nach einzeln erzeugten vektorartigen T-Quarks mit einer elektrischen Ladung +2/3 und Y-Quarks mit einer elektrischen Ladung von -4/3 vorgestellt. Diese exotischen Teilchen werden von verschiedenen Modellen jenseits des Standardmodells vorhergesagt, welche versuchen das Verständnis der elektorschwachen Symmetriebrechung zu erweitern und somit das Naturalness Problem zu lösen. Hierfür werden die in 2015 und 2016 bei einer Schwerpunktsenergie von 13 TeV und einer integrierten Luminosität von 36.1 inversen fb vom ATLAS Detektor am LHC aufgezeichneten Proton-Proton-Kollisionen ausgewertet. Die Ereignisselektion ist auf leptonisch zerfallende W-Bosonen der Y/T nach Wb Zerfälle ausgerichtet, weshalb ein hochenergetischer, von einem Bottom-Quark stammender Jet, ein einzelnes Lepton, ein in Vorwärtsrichtung emittierter Jet sowie fehlende transversale Energie, neben verschiedenen Isolationskriterien, verlangt wird.
Es konnte keine signifikante Abweichung zur Vorhersage des Standardmodells gemessen werden. Aus diesem Grund wurden obere Grenzen for die Kopplungsstärke und den Mischungswinkel von T-Quarks in einem Singulett-Modell sowie Y-Quarks eines (B,Y)-Dublett bzw. (T,B,Y)-Triplett-Modells mit Quarks der dritten Generation des Standard Modells bestimmt. Hierbei wurden erstmalig Interferenzeffekte mit Standardmodellprozessen berücksichtigt. Die obere Grenze für den Mischungswinkel wurden für ein T-Singulett-Modell bei einer Masse von 800 GeV zu |sin(theta_L)|= 0.18, für ein Y eines (B,Y)-Dublett-Modells zu |sin(theta_R)|= 0.17 sowie für ein Y eines (T,B,Y)-Triplett-Modells zu |sin(theta_L)|= 0.16 bestimmt. Die ermittelten Grenzen innerhalb des (B,Y)-Dublett-Modells im Massenbereich 800 GeV bis 1250 GeV sind zu indirekten, aus elektroschwachen Präzisionsvariablen abgeleiteten Schranken kompetitiv.This thesis presents a search for singly produced vector-like T quarks with charge +2/3 or Y quarks with charge -4/3. These exotic particles are predicted by several beyond-the-standard-model theories which try to shed light on the mechanism of electro-weak symmetry breaking, thus addressing the Naturalness Problem. The analysis is performed on a proton-proton collision data set with an integrated luminosity of 36.1 inverse fb at a centre-of-mass energy of 13 TeV recorded in 2015 and 2016 by the ATLAS detector at the LHC. The focus is on leptonically decaying W bosons from Y/T to Wb decays of the heavy quarks and the event selection requires a jet leading in transverse momentum and being b-tagged, exactly one lepton, a forward jet as well as missing transverse energy beside several isolation requirements.
No significant deviation from the expected Standard Model background is observed. Therefore, upper limits on the coupling strength and mixing angle between third generation Standard Model quarks and a T from a singlet model as well as a Y from a (B,Y) doublet or a (T,B,Y) triplet model are computed using the CLs method. This search represents the first analysis in which the interference effects with the Standard Model background are taken into account. The smallest upper limits are found to be |sin(theta_L)|= 0.18 for a T singlet for a mass of 800 GeV, |sin(theta_R)|= 0.17 in the (B,Y) doublet case at 800 GeV and |sin(theta_L)|= 0.16 for the (T,B,Y) triplet model. The observed limits on the mixing parameter |sin(theta_R)| are competitive with indirect bounds from electroweak precision observables in the mass range between about 800 GeV and 1250 GeV
