    Excerpts from Television\u27s Greatest Hits and Other Stories

    The short stories contained in this manuscript are mostly of the realist stripe, with a few concessions made to my more fabulist tendencies. Each is about men and women being forced to relive their old lives or finding themselves at the cusp of new ones, propositions which prove simultaneously attractive and repulsive. By the end of each story, it is my hope to transmit that the characters have survived somewhat intact, though reconstituted. There is a man in grief over the death of the wife he couldn’t stop cheating on, adults trick-or-treating at the expense of their children’s youths, a young woman who obsesses after a high school crush post-divorce. Former enfant terribles get the band back together for reasons that compromise their ethos. Best friends disappear into thin air. A young man is forced to face the consequences of his tendencies toward historical revisionism in his art. An all-night lock-in at a skating rink serves as the venue for confrontations intimate and violent. Ultimately, my hope is that these stories say something about desperate people and what happens when our nostalgia is brought into conflict with the inevitability of aging, the things we create, and how others see us

    The Effect of Used Broiler Litter on the Growth and Persistence of Campylobacter

    Litter is a possible source of Campylobacter colonization for broilers as well as contamination of crops when used as fertilizer. A survey of Arkansas broiler litter indicated that Campylobacter recovery rates were higher in pine shavings and rice hulls than sand. Two experiments utilized three types of litter, which were artificially contaminated with Campylobacter. After 24 hours no Campylobacter could be recovered from any sample. Campylobacter growth was also examined for used pine shaving litter in varying conditions: aerobic atmosphere, micro aerobic atmosphere (6% O2), and moisture content. Campylobacter was recovered for all treatments at the initial sampling, and by the 12 hour sampling time, only the added moisture and micro aerobic atmosphere yielded recoverable Campylobacter. This research suggests that without birds present in the house to shed fresh Campylobacter cells onto the litter, that the litter itself is incapable of harboring the bacteria long enough to colonize sequential flocks

    What Comes After Longing

    What Comes After Longing is a collection of artifacts from my research exploring the desires and haunting motivations of the human experience. Is all life longing for something, some place, somebody, some time? That is the question I pose. What is the purpose of longing? Is it meaningless to long for something if you’re longing for something that’s not real? We filter our experience of the world through this longing. Longing is the filter through which we survive, and my research and work explores whether we can get past this, or whether all life is a series of these longings. The film, music, poetry, and paintings in this body of work stand testament to the way we digest and come to terms with tangible reality through our own internal filter. Referencing portraiture and landscape scenes and scenarios both old and new, true and untrue, the work is a catalyst for a possibly futile attempt to answer a question that has no answer but remains in a nebulous location such as most endeavors in life

    Is Resorption of the Temporomandibular Joint Related to Various Orthodontic Treatment Modalities, Dental Characteristics or Craniofacial Form?

    Introduction: Degenerative joint disease (DJD) or condylar resorption (CR) is mildly prevalent in a pre-orthodontic population and theoretically could contribute to jaw pain and skeletal relapse following orthodontic treatment. Purpose: To determine whether craniofacial form, dental characteristics or particular orthodontic treatment modalities are related to bony condylar degeneration. Materials and methods: 174 subjects were divided into three groups based on the grade of condylar resorption. 1) moderate-severe condylar resorption, 2) mild condylar resorption and 3) no condylar resorption (as diagnosed from panoramic radiographs). Lateral cephalometric radiographs were traced at initial presentation (Tl) and treatment factors were recorded. Groups were compared for differences in skeletal, dental and modalities of orthodontic treatment. Bony condylar change over time was also measured and compared between those with a history of orthognathic surgery and those without. Results: Cephalometric findings of statistical significance among those with moderate- severe condylar resorption included increased vertical skeletal measurements (increased Y-axis, SN-PP, SN-OP, SN-MP, UFH, MPA, gonial angle, decreased P-AFH% and facial axis), increased overjet, decreased Ll-MP, increased NLA, decreased SNA, SNB and maxillomandibular differential when compared to the other groups. Treatment modalities of statistical significance included a history of orthognathic surgery (three­ fold relative risk) and increased treatment time. Conclusions: Results from this study indicate that risk factors for condylar resorption include a dolichofacial type with increased overjet, extended treatment length and orthognathic surgery

    Identifying Ancestral Origin using a Novel Panel of Single Nucleotide Polymorphism Locations

    Get PDF
    A novel panel of single nucleotide polymorphisms (SNPs) used in the classification of ancestral origin is proposed. The panel is motivated by recent results in human identification and categorization using soft biometrics. The panel makes use of SNPs related to the height and ear size of an individual. The classifier proposed in this thesis is a standard maximum-likelihood classifier that matches an individual to the ancestral profile closest to the individual. This method produces results with lower error rates than other proposed methods.;This thesis proposes a new distinct panel of 55 single nucleotide polymorphisms for determining ancestral origin. This panel was later reduced to two panels of 18SNPs and 22SNPs respectively. This new approach is producing a high success rate, and has great promise for future progress. This panel is unique in that all prior research has made use of SNPs related to skin pigmentation since this is considered the most readily identifiable difference between different ancestral groups. We chose to use the four common ancestry groups of African American, Asian, European, and Sub-Saharan African.;The proposed panel of 55 SNPs had a successful classification rate of 98% when tested on simulated data, while the 22 SNP panel when tested on real data had a successful classification rate of 86% due to SNP availability issues in the real data. Using a knockout procedure, the 55 SNP panel was reduced to an 18 SNP panel that had a successful classification rate of 99.8% on simulated data

    International audienceUsing the powerful machinery available for reduced words of type BB, we demonstrate a bijection between centrally symmetric kk-triangulations of a 2(n+k)2(n + k)-gon and plane partitions of height at most kk in a square of size nn. This bijection can be viewed as the type BB analogue of a bijection for kk-triangulations due to L. Serrano and C. Stump.En utilisant la machinerie puissante pour mots réduits de type BB, nous démontrons une bijection entre les kk-triangulations centralement symétriques d’un 2(n+k)2(n + k)-gon et les partitions de plans de hauteur inférieure ou égale à kk dans un carré de taille nn. Cette bijection peut être considérée comme l’analogue de type BB d’une bijection de kk-triangulations due à L. Serrano et C. Stump

    The Psychological Impact of Disaster Relief Work on Disaster Relief Volunteers in North America

    Get PDF
    This study investigated the psychological effects that disaster relief work has on disaster relief volunteers in North America. It provided the necessary framework for research that was conducted to examine if disaster relief volunteers are more vulnerable to developing posttraumatic stress disorder (PTSD) after they volunteer in disaster relief or if they become more resilient and develop posttraumatic growth (PTG) instead. This quantitative study also provided research questions and hypotheses and is a road map for future research. Disaster relief volunteers provide many irreplaceable services to the field of disaster relief. Understanding how disaster relief volunteers are impacted by the trauma they witness strengthens the research field. It allows for adjustments to be made so that disaster relief volunteers are trained and cared for so that they will have the desire to volunteer for future relief efforts. While other studies have researched similar impacts that disaster relief work has on volunteers, few have focused on volunteers serving in relief efforts in North America. Finally, this dissertation exposed the research gap and explained why this research is relevant to the field and what next steps should be taken
