Jessica Hagedorn, 19th Annual ODU Literary Festival
No full textJessica Hagedorn Born and raised in the Philippines, Jessica Hagedorn is well-known as a performance artist, poet, and playwright. She is the author of the novel Dogeaters (Penguin), which was nominated for the National Book Award. Hagedorn wrote the screenplay for Fresh Kill, an independent first feature film directed and produced by Shu Lea Cheang and has collaborated on film projects, Color Schemes and Those Fluttering Objects of Desire. Her multimedia theater pieces include Teenytown, The Art of War: Nine situations, and Holy Food. Hagedorn is the recipient of a 1994 Lila Wallace Reader’s Digest Writers Award, and a 1995 NEA Creative Writing Fellowship. Her new novel, The Gangster of Love has been recently released by Houghton Mifflin
Divergent histories of rDNA group I introns in the lichen family Physciaceae
No full textThe wide but sporadic distribution of group I introns in protists, plants, and fungi, as well as in eubacteria, likely resulted from extensive lateral transfer followed by differential loss. The extent of horizontal transfer of group I introns can potentially be determined by examining closely related species or genera. We used a phylogenetic approach with a large data set (including 62 novel large subunit [LSU] rRNA group I introns) to study intron movement within the monophyletic lichen family Physciaceae. Our results show five cases of horizontal transfer into homologous sites between species but do not support transposition into ectopic sites. This is in contrast to previous work with Physciaceae small subunit (SSU) rDNA group I introns where strong support Was found for multiple ectopic transpositions. This difference in the apparent number of ectopic intron movements between SSU and LSU rDNA genes may in part be explained by a larger number of positions in the SSU rRNA, which can Support the insertion and/or retention of group I introns. In contrast. we suggest that the LSU rRNA may have fewer acceptable positions and therefore intron spread is limited in this gene
Reading: Jessica Bruder
No full textIn this audiovisual recording from Thursday, March 24, 2022, as part of the 53rd Annual UND Writers Conference: “Communities and the Individual,” Jessica Bruder reads excerpts from Nomadland. Bruder discusses what it means to be an immersion journalist and what brought her to write Nomadland. Bruder also responds to audience questions about the dynamic between author and those who share their stories for a novel like Nomadland, the connection between immersive journalism and the new journalism literary movement, the process of collecting, organizing, and transforming material into a novel, how faithful the film version of Nomadland was to the book, and if Linda ever got to build her Earthship.

Sequential Derivatization of Polar Organic Compounds in Cloud Water Using O-(2,3,4,5,6-Pentafluorobenzyl)hydroxylamine Hydrochloride, N, O-Bis(trimethylsilyl)trifluoroacetamide, and Gas-Chromatography/Mass Spectrometry Analysis
No full textCloud water samples from Whiteface Mountain, NY were used to develop a combined sampling and gas chromatography-mass spectrometric (GCMS) protocol for evaluating the complex mixture of highly polar organic compounds (HPOC) present in this atmospheric medium. Specific HPOC of interest were mono- and di keto-acids which are thought to originate from photochemical reactions of volatile unsaturated hydrocarbons from biogenic and manmade emissions and be a major fraction of atmospheric carbon. To measure HPOC mixtures and the individual keto-acids in cloud water, samples first must be derivatized for clean elution and measurement, and second, have low overall background of the target species as validated by GCMS analysis of field and laboratory blanks. Here, we discuss a dual derivatization method with PFBHA and BSTFA which targets only organic compounds that contain functional groups reacting with both reagents. The method also reduced potential contamination by minimizing the amount of sample processing from the field through the GCMS analysis steps. Once derivatized only gas chromatographic separation and selected ion monitoring (SIM) are needed to identify and quantify the polar organic compounds of interest. Concentrations of the detected total keto-acids in individual cloud water samples ranged from 27.8 to 329.3 ng mL-1 (ppb). Method detection limits for the individual HPOC ranged from 0.17 to 4.99 ng mL-1 and the quantification limits for the compounds ranged from 0.57 to 16.64 ng mL-1. The keto-acids were compared to the total organic carbon (TOC) results for the cloud water samples with concentrations of 0.607 to 3.350 mg L-1 (ppm). GCMS analysis of all samples and blanks indicated good control of the entire collection and analysis steps. Selected ion monitoring by GCMS of target keto-acids was essential for screening the complex organic carbon mixtures present at low ppb levels in cloud water. It was critical for ensuring high levels of quality assurance and quality control and for the correct identification and quantification of key marker compounds.Corrected proof of accepted manuscrip
Structural and quantitative neuroimaging of the common marmoset monkey using a clinical MRI system
No full textPurpose was to adapt structural and quantitative magnetic resonance imaging (MRI) from humans to common marmoset monkeys on a clinical 3T scanner and to demonstrate the value for translational research.Three-dimensional T1- and T2-weighted MRI and gradient echo-based multi-parameter mapping was performed on nine adult animals using a wrist coil. Structural MRI was applied in a model of targeted experimental autoimmune encephalomyelitis (EAE). Magnetization transfer (MT) and T1 parameter maps were used to depict axon-rich cortical areas. After intraveneous triple dose of gadobutrol, the excretion half-time was determined from consecutive measurements of R1 = 1/T1. Diffusion tensor imaging (DTI) was performed at 1 mm resolution.At 0.4 mm resolution, total measurement time (30 min) was compatible with injection anesthesia, permitting rapid screening and frequent follow-up. Structural MRI depicted the EAE lesion in white matter. Quantitative values of T1, MT, and R2 in marmoset brain were comparable to humans, except for smaller R2 indicating lower iron content in basal ganglia. The middle temporal V5 area and the cortical layer IV could be identified, but were considerably better delineated when averaging two images at 0.33 mm resolution (70 min). A similar distribution volume (23%), but a shorter excretion half time than in humans (30 min) was observed. DTI was feasible only in larger structures, such as major axonal tracts.High-resolution MRI of common marmosets proved feasible using clinical MRI hardware. A rapid 3D examination protocol was established for screening under injection anesthesia, thus avoiding the adverse effects of inhalation anesthesia
