The Middle Of The Middle: Purgatory, Pilgrimage, And Human And Plant Mobility In A Time Of Climate Crisis, Stephen S. Collis

The Goose

This paper, adapted from a talk given for the Institute of the Humanities at Simon Fraser University on April 26 2023, explores intersecting issues taken up by an in-progress long poem I am currently writing. That long poem, “The Middle,” explores questions of climate displacement, migration, and refuge via a writing-though of Dante’s Purgatorio—itself a poem of pilgrimage. A further context for both the poem and the paper about the poem is an ongoing project of walking in solidarity with refugees, asylum seekers, and immigration detainees that the author has been involved with since 2015. In seeking to “override …

On Foot, Dee Hobsbawn-Smith

The Goose

“On Foot” is an interdisciplinary examination of the importance of walking and running to the creative life. It is primarily a personal essay braided together with free verse poetry and a small proportion of inquiry into a few famous thinkers and writers who walked regularly. The essay traces a serious foot injury and the effects of that trauma, coupled with the threat of loss of sight, on a writer with a long history of walking and running as part of their creative process. The five poems unspool the sights and sounds of the natural rural world where they walk daily, …

Manipulating And Assaying Chromatin Architecture Around Enhancer Elements In Vivo, John Lawrence Carter

Theses and Dissertations

There are about 20,000 genes in the human genome. The lowly nematode worm, C. elegans, has about the same number of genes. How could two organisms that are so different arise from a similar number of genes? The answer is epigenetics, or the factors that help control when and where genes are expressed. There are many layers that comprise the epigenetic control of genes. One of which is the structure or architecture of chromatin. Chromatin is a complex of DNA and proteins. Histone proteins with DNA wrapped around them form the fundamental component of chromatin, the nucleosome. Chromatin exists in …

Probability Distributions Arising In Connection With The Inspection Paradox For Bernoulli Trials., James E. Marengo, Anne Marino Himes, W. Cade Reinberger, David L. Farnsworth

Articles

In renewal theory, the Inspection Paradox refers to the fact that an interarrival period in a renewal process which contains a fixed inspection time tends to be longer than one for the corresponding uninspected process. We focus on the paradox for Bernoulli trials. Probability distributions and moments for the lengths of the interarrival periods are derived for the inspected process, and we compare them to those for the uninspected case.

Domain Specific Feature Representation Learning For Diverse Temporal Data, Farhan Asif Chowdhury

Computer Science ETDs

Humans can leverage domain context to recognize novel patterns and categories based on limited known examples. In contrast, computational learning methods are not adept at exploiting context and require sufficient labeled examples to achieve similar accuracy. Many temporal data domain, for example, seismic signals and oil mining sensor data, requires domain expert annotation, which is both costly and time-consuming. The dependency on training data limits the applicability of machine learning algorithms for domains with limited labeled data. This dissertation aims to address this gap by developing temporal mining algorithms that exploit domain context to learn discriminative feature representation from limited …

Based on in-depth interviews coupled with extensive research, the book highlights the double marginalization that can occur due to secondary employment status in …

Dry Reforming Of Methane Over Substituted Lanthanum Zirconate Pyrochlore Catalysts, Srikar Bhattar

LSU Doctoral Dissertations

One of the potential methods for producing syngas from two greenhouse gases (CH₄ and CO₂) is dry reforming of methane (DRM), which has received a lot of attention. DRM could lower the net emission of these gases if the energy used to power it comes from sources other than hydrocarbons. Despite being highly active, many conventional Ni based metal/support catalyst systems rapidly lose their activity due to the sintering or deposition of coke on the metal clusters' surfaces. Thus, it is crucial that the DRM catalyst must be coke resistant and thermally stable to avoid sintering.

Development Of Novel Biosensors For Direct Measurement Of Proteasome Activity In Intact Single Cells, Alireza Rahnama

LSU Doctoral Dissertations

Enzymes regulate nearly all cellular and biochemical processes governing cellular proliferation, metabolism, and migration. One example is the ubiquitin-proteasome system (UPS), a highly complex, tightly regulated pathway responsible for the recognition and degradation of misfolded or damaged proteins inside the cell. Protein degradation requires posttranslational addition of a polyubiquitin chain to target the protein to the proteasome for degradation which can be reversed by deubiquitinating enzymes (DUBs) which remove the chain. Dysregulation of the UPS is associated with many diseases including cancer which has resulted in the development of inhibitors, like Bortezomib and Carfilzomib, driving higher median patient survival rates …

A family member, friend, or peer often plays a key role in initially identifying, rescuing, and then supporting ongoing recovery efforts of someone at risk for suicide. Preparation is provided through suicide prevention gatekeeper training such as QPR, yet this partner of direct professional service providers often lacks adequate support to effectively perform gatekeeper behaviors leading to the research question, "Does virtual café support effective gatekeeper behaviors?" The project uses a mixed-method approach to determine if a focused discussion group using The World …

Evolutionary Conservation And Times Of Action Of Heterochronic Genes, Maria Ivanova

Theses and Dissertations

The heterochronic pathway of C. elegans is the most well-characterized system to date for controlling the sequence and timing of developmental events. However, we still have critical unanswered questions to address. First, little is known about the evolution of the heterochronic pathway, and of developmental timing in general. To determine if the roles of major heterochronic genes are conserved, I made mutants in orthologs of these genes in C. briggsae, using CRISPR/Cas9. My studies revealed a significant drift in the roles of some of the genes, although all of them are still involved in the developmental timing regulation, and several …

Urinary Tract Infections: A Review Of The Current Diagnostics Landscape, Braith Grey, Mathew Upton, Lovleen Tina Joshi

School of Biomedical Sciences

Urinary tract infections are the most common bacterial infections worldwide. Infections can range from mild, recurrent (rUTI) to complicated (cUTIs), and are predominantly caused by uropathogenic Escherichia coli (UPEC). Antibiotic therapy is important to tackle infection; however, with the continued emergence of antibiotic resistance there is an urgent need to monitor the use of effective antibiotics through better stewardship measures. Currently, clinical diagnosis of UTIs relies on empiric methods supported by laboratory testing including cellular analysis (of both human and bacterial cells), dipstick analysis and phenotypic culture. Therefore, development of novel, sensitive and specific diagnostics is an important means to …

Integrating A Virtual Science Outreach Into The Science Classroom Through Participatory Action Research, Shelby Anne Montague

Electronic Theses and Dissertations Archive

Calls for increased involvement in science outreach have come from scientists (Alberts, 2018; Friedman, 2008), from professional organizations (Jayaratne et al., 2003; Lee, 2018; Toolin, 2004) and from funding agencies (Broadening Participation, 2008; Catsambis, 1995) to increase students’ interest in science, technology, engineering, and mathematics (STEM) and STEM careers. One model of science outreach is the scientist in the classroom model, where a STEM professional visits a school classroom either in-person (Peker et al., 2012; Pratt and Yezierski, 2018) or virtually (Barry et al., 2022; McCombs et al., 2007). The St. Jude Virtual Journal Club is a scientist in the …
