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
A Volumetric Proof of the Log-Concavity of the Characteristic Polynomial of Matroids
No full textThis thesis presents a novel proof of the Heron–Rota–Welsh conjecture using a volume theoretic approach. Originating in the 1950's, the conjecture proposes that the coefficients of the characteristic polynomial of a matroid exhibit the property of log-concavity. A complete proof for all matroids was found only in 2018, when Jun Huh, in collaboration with Karim Adiprasito and Eric Katz, achieved this milestone by developing the theory of combinatorial Hodge theory. We review the link between the combinatorial data of matroids, algebraic objects known as Chow rings, and geometric objects called Bergman fans, and then outline the recent work of Dustin Ross, Anastasia Nathanson, Lauren Nowak, and the author on the theory of normal complexes of fans and their volumetric properties. Our main result stems from showing that the Bergman fans of matroids meet criteria such that the (extended) mixed volumes of their normal complexes obey the Alexandrov–Fenchel inequality, yielding log-concave sequences. We hope this demonstrates that the theory of normal complexes is a tool able to tackle modern problems in mathematics
The relationship between depression and chronotype: A longitudinal assessment during childhood and adolescence
No full textBackground/Objective
During adolescence, chronotype shifts towards “eveningness.” “Eveningness” is related to negative physical and mental health outcomes. Little is known about what influences the shift in chronotype beyond pubertal status. The current study examined the influence of earlier depression predicting later individual differences in adolescent chronotype, accounting for pubertal status, and the prospective prediction of later increases in depression from earlier chronotype.
Methods
Youth (age M=12.06, SD=2.35; 56.5% girls) from the community completed repeated assessments of depression, including both self-reports (14 assessments) and diagnostic interviews (8 assessments), over a 48-month period. At the 36-month time-point, participants completed chronotype and pubertal development measures. Regression and ANOVA analyses examined: (1) the influence of earlier depression levels (baseline to 36-months) upon chronotype, and (2) chronotype (at 36 months) upon later depression (48 months).
Results
Youth with higher earlier depression symptoms (β=-.347, p<.001) and history of depression diagnosis (β=-.13, p=.045) showed a greater eveningness preference controlling for pubertal status, age and gender. Further, depression diagnosis history interacted with pubertal status to predict chronotype: (F(1,243)=4.171, p=.045) such that the influence of depression on chronotype was greatest among postpubertal youth (t=3.271, p=.002). Chronotype (greater eveningness preference) predicted prospective increases in depression symptoms (β=-.16, p=.03) and onset of depressive episode (b=-.085, OR=.92, p=.03) one year later.
Conclusion
Depression, experienced earlier in life, predicts greater preference for eveningness, especially among postpubertal youth. In turn, later depression is predicted by evening preference. These findings suggest the reciprocal interplay between mood and biological rhythms, especially depression and chronotype, during adolescence.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2019-12-01The student, Dustin Haraden, accepted the attached license on 2017-12-12 at 16:34.The student, Dustin Haraden, submitted this Thesis for approval on 2017-12-12 at 16:40.This Thesis was approved for publication on 2017-12-13 at 08:22.DSpace SAF Submission Ingestion Package generated from Vireo submission #11961 on 2018-03-13 at 10:38:25Made available in DSpace on 2018-03-13T17:35:57Z (GMT).
