In Remembrance of Emmett Till: Regional Stories and Media Responses to the Black Freedom Struggle
No full textOn August 28, 1955, fourteen-year-old Chicago native Emmett Till was brutally beaten to death for allegedly flirting with a white woman at a grocery store in Money, Mississippi. Roy Bryant and J. W. Milam were acquitted of murdering Till and dumping his body in the Tallahatchie River, and later that year, an all-white grand jury chose not to indict the men on kidnapping charges. A few months later, Bryant and Milam admitted to the crime in an interview with the national media. They were never convicted.
Although Till’s body was mutilated, his mother ordered that his casket remain open during the funeral service so that the country could observe the results of racially motivated violence in the Deep South. Media attention focused on the lynching fanned the flames of regional tension and impelled many individuals—including Rosa Parks—to become vocal activists for racial equality.
In this innovative study, Darryl Mace explores media coverage of Till’s murder and provides a close analysis of the regional and racial perspectives that emerged. He investigates the portrayal of the trial in popular and black newspapers in Mississippi and the South, documents posttrial reactions, and examines Till’s memorialization in the press to highlight the media’s role in shaping regional and national opinions. Provocative and compelling, In Remembrance of Emmett Till provides a valuable new perspective on one of the sparks that ignited the civil rights movement.
Darryl Mace is associate professor and chair in the Department of History and Political Science at Cabrini College.
Well-conceived and well-executed. Mace delineates the \u27situational\u27 regionalism that arose during the Emmett Till Coverage, that it was not static, but rather the coverage was a response to people’s views of the place in which they lived and how their locale compared to the rest of the nation. This book provides a textual analysis of the coverage of Emmett Till’s lynching, funeral, trial, post-trial reactions; and memorials of Till found in popular mainstream newspapers and popular black newspapers. -- Deborah F. Atwater, author of The Rhetoric of African American Women
Mace\u27s writing is clear and accessible. He offers interesting and valuable insight into the varied media coverage of Emmett Till’s lynching and what it illustrates about racial attitudes across the country. -- Emilye Crosby, author of A Little Taste of Freedom and editor of Civil Rights History from the Ground Up
Historians have long-agreed with David Halberstam that the lynching of Emmett Till and the trial of his murderers was ‘the first great media event of the civil rights movement.’ Until now, however, no one has made the case as thoroughly and persuasively as Darryl Mace does in this landmark study. His exhaustive analysis of the national and regional newspaper coverage is a model of careful and creative scholarship, and if you want to understand how the Till lynching helped to change our national conversation about race, you would do well to begin here. -- Christopher Metress, editor of The Lynching of Emmett Till: A Documentary Narrative
Mace gives readers ample opportunity to understand why Till\u27s violent death wasn\u27t just another senseless murder, why the U.S. was ripe for Civil Rights progress made in the decade after his slaying; and how the press, especially sixty years ago, served its public. -- Terri Schilenmeyer -- Tennessee Tribune
He reminds us just how important the Till murder and trial were for the future of the Freedom Struggle… [Mace] still helps keep this story alive. -- Southern Spaces
[A] much-needed addition to the Till literature[. . . . B]y the time I finished In Remembrance of Emmett Till, I was struck, powerfully so, by the impact of racism rather than regionalism on the writing of Emmett Till’s memory. -- American Historical Reviewhttps://uknowledge.uky.edu/upk_african_american_studies/1032/thumbnail.jp
Conducting hydrologic research with hobbyist electronics: Gaining new insights into stemflow processes with low-cost custom sensor platforms
No full textThe need for greater spatiotemporal resolutions has been a key constraint in the study of the hydrology of vegetated surfaces. Of particular importance to further understanding is the capability to link intra-storm dynamics of interception of precipitation to the meteorological conditions which produced it. Within the study of interception, the dynamics of precipitation routed from the canopy down a plant’s stem (stemflow) represents a significant and highly variable localized input of water. In this study, a “maker” approach is applied to demonstrate a new sensing system which leverages the low-cost and accessibility of hobbyist electronic components in the monitoring of stemflow production. A case study highlighting the performance of the new sensing system serves to demonstrate the potential utility and effectiveness of these low-cost platforms in linking the intra-storm variability of stemflow production to the overall meteorological conditions.Not peer reviewe
The safety profile of perflutren microsphere contrast echocardiography during rest and stress imaging: Results from an Australian multicentre cohort
No full textBackground: Contrast enhanced echocardiography (CEE) is utilised when sub-optimal image quality results in non-diagnostic echocardiograms. However, there have been numerous safety notices issued by regulatory authorities regarding rare but potentially serious adverse reactions (AR). This multi-centre, retrospective analysis was performed to assess the short-term safety of CEE in a broad range of indications. Methods: All CEE performed over 58 months at three institutions were assessed for AR within 30. min. Results: A total of 5956 CEE were performed in 5576 patients. A total of 4903 were stress CEE and 1053 resting CCE. Bolus administration in 5719, infusion in 237 cases; 89.9% of CCE were outpatients. Commonest CEE indication was functional stress testing (82.3%). There were 16 AR related to CEE (0.27%). All AR were mild, transient and all patients made a full recovery. No cases of serious anaphylaxis or death within 30. min of contrast administration. Comparing those with and without an AR, there were no significant differences in age, gender, BMI, LVEF, patient location, exam type or RVSP. There was a slightly increased likelihood of an AR during infusion versus bolus dosing (p= 0.02). Conclusion: CEE is a safe investigation in a broad range of indications and clinical scenarios. AR are very rare, mild and transient
Zirconium complexes of fluorinated aryl diamides
No full textThe reaction of excess ArFNHLi with (ICH2CH2OCH2)2 affords the new diamines (ArFNHCH2CH2OCH2)2 (1, ArF = C6F5; 2, ArF = 3,5-C6H3(CF3)2) in moderate yield. Direct protonolysis of Zr(CH2Ph)nCl4-n (n = 2−4) or Zr[N(SiMe3)2]nCl4-n (n = 2, 3) with 1 or 2 (1 equiv) affords the zirconium complexes Zr(ArFNCH2CH2OCH2)2(X)(Y) (ArF = C6F5: 3, X = Y = Cl; 4, X = N(SiMe3)2, Y = Cl; 5, X = Cl, Y = CH2Ph; 6, X = Y = CH2Ph. ArF = 3,5-C6H3(CF3)2: 7, X = Y = Cl; 8, X = Y = CH2Ph). The structures of 1, 4, 5, and 7 were established by X-ray crystallography with the zirconium complexes 4, 5, and 7 all adopting a monocapped trigonal bipyramidal geometry in the solid state. However, in solution, these complexes display higher symmetry due to rapid ligand rearrangement. The silylamido complex 4 shows restricted rotation of the C6F5 rings in solution (ΔG⧧ = 49 ± 3 kJ mol-1). Abstraction of a benzyl group from 6 by B(C6F5)3 affords {Zr[CH2OCH2CH2N(C6F5)]2(CH2Ph)}+{(PhCH2)B(C6F5)3}- (9). This complex shows evidence for η2-benzyl coordination and does not polymerize ethylene at room temperature. Treatment of 3 with excess MAO (500 equiv) and ethylene (1 atm, 50 °C) affords polyethylene at a modest rate (3.2 kg mol-1 Zr h-1).Peer reviewedFinal article publishe

Ecological Pressures Selecting for Singing Behavior in Primates
No full textThesis (Ph.D.)--University of Washington, 2019This dissertation explores the social, behavioral, and habitat based influences on the evolution of elaborate vocalizations in primates. The goals of this project were to merge and test hypotheses derived from both the primate morphological origins literature and the musical behavior origins literature. Theoretical elements from the leaping and arboreal hypotheses from the primate origins literature were brought to bear on vocal display data from extant primates and on theories on the function of song in animals and music in humans. Specifically, I used computational statistical techniques to test the dual hypotheses that precision limb landing, as required in navigating complex arboreal topologies, could have not only shaped primate morphology, but also evolutionarily shaped their vocal signaling behaviors. I also tested other theories from the literature on both animal communication (e.g. the acoustic adaptation hypothesis) and human music (e.g. coalition signaling as well as group and pair bonding). I collected behavioral data, for as many species (n) as possible, from the primary primate behavioral literature, including vocalization (n=68), locomotion (n=99), and socio-ecological regression control variables. Data were then analyzed in three separate substantive chapters. First, in chapter 2, spectrographic vocalizations were scored manually along ethnomusicologically universal acoustic parameters and subsequently reduced into a univariate acoustic reappearance diversity index [ARDI], reflecting call elaborateness. Second, in chapter 3, quantitative locomotion activity data (e.g. leaping and swinging percentages) were harvested from the positional behavior primary literature in order to both estimate its ancestral influence on morphology as well as to create better (non-binary) predictor variables for testing vocal display origin theories. Third, in chapter 4, I tested for my hypothesized co-evolutionary relationship while controlling for phylogeny. ARDI was highest in smaller, socially monogamous, and forest living groups, as well as positively associated with swinging and leaping. These results are consistent with the dual hypothesis that both elaborate vocal displays and vision changes in primates could have evolved as a result of increased demand for precision limb landing locomotion. In chapter 5, I discuss the limitations and drawbacks as well as the theoretical significance, scientific relevance, broader implications, and ideas for future research
Making the case for improved structural design : tornado outbreaks of 2011
No full textA total of 1,625 tornadoes occurred in the United States in 2011, resulting in economic losses that exceeded $25 billion. Two tornado outbreaks stand out because they caused more than half of those losses. The tornadoes that cut through Tuscaloosa, Alabama, on April 27 and Joplin, Missouri, on May 22 were responsible for a combined 223 fatalities and more than 13,000 damaged buildings in the two cities. Although the economic losses associated with tornado damage are well documented, the writers argue that the overall impact should encompass longer term, broader considerations such as the social disruption and psychological effects that impact communities. This paper examines observations by tornado damage assessment teams led by the first author in these two medium-sized cities and suggests that the evolution of building codes and past approaches to construction have led to conditions that made this extent of damage possible. The authors outline a multidisciplinary path forward that incorporates engineering research and social and economic studies into a new design paradigm leading to building code changes and social practices that will improve resistance and mitigate future losses at a community level from tornadoes

Visual Amplification The visual presentation of new music, practical applications in performance, curation, & composition.
No full textVisual Amplification, the visual presentation of new music in composition, performance and curation explores the
role that visual information plays in our perception of sound and musical performance, specifically in relation to
the presentation of new music (contemporary classical music).
This dissertation will show that a conscious understanding of the power of context over the communication of a
musical work is fundamental to creating high quality and engaging musical experiences.
Through theoretical discussion, a review of current practices in the professional music community and the
presentation of a collection of original creative works, the research outlines the extent to which visual stimuli can
impact the reception of musical work and proposes varied strategies to incorporate this information to maximize
audience engagement.
The research conducted draws on interviews with Jennifer Walshe, Steven Takesugi, Simon Steen-Andersen,
Darryl Buckley, David Chisholm, Stefan Prins, Daniel Lineham, & Jean-Luc Plouvier. Examples from performances
curated by the author with musical groups soundinitiative and scapegoat are also used as case studies
