Poetries Of Abandonment: A Study Of Plath And Glück, Yara Abdelmoneim May 2025

Poetries Of Abandonment: A Study Of Plath And Glück, Yara Abdelmoneim

Theses and Dissertations

This thesis explores the intersection between literature and trauma, which can be discerned in the key works of two poets, Sylvia Plath and Louise Glück. While offering readings of crucial poems, the thesis also examines the interrelations among trauma, memory and narrative as theorized by two contemporary psychiatrists, Bessel van der Kolk and Judith Herman. Both Plath and Glück wrote about personal and generational trauma after going through different experiences of abandonment. Absence, indirection and repetition provide the basis for literary techniques that allow their traumas to be better understood by authors and readers alike. The degree to which each …

Corradjust Unveils Biologically Relevant Transcriptomic Correlations By Efficiently Eliminating Hidden Confounders, Stepan Nersisyan, Phillipe Loher, Isidore Rigoutsos

Computational Medicine Center Faculty Papers

Correcting for confounding variables is often overlooked when computing RNA-RNA correlations, even though it can profoundly affect results. We introduce CorrAdjust, a method for identifying and correcting such hidden confounders. CorrAdjust selects a subset of principal components to residualize from expression data by maximizing the enrichment of "reference pairs" among highly correlated RNA-RNA pairs. Unlike traditional machine learning metrics, this novel enrichment-based metric is specifically designed to evaluate correlation data and provides valuable RNA-level interpretability. CorrAdjust outperforms current state-of-the-art methods when evaluated on 25 063 human RNA-seq datasets from The Cancer Genome Atlas, the Genotype-Tissue Expression project, and the Geuvadis …

Staff Education To Improve Patient Outcomes And Treatment Compliance Through Use Of Motivational Interviewing In The Mental Health Setting, Rachel Nardi

Walden Dissertations and Doctoral Studies

Summary: Treatment noncompliance is a significant problem within the realm of mental health care. Recurrent noncompliance increases symptom severity, the likelihood of a crisis, and the burden placed on mental health care resources. Motivational interviewing (MI) is an evidence-based practice (EBP) demonstrated through extensive research to positively affect patient outcomes. Teaching MI to mental health care providers is one option organizational leaders can choose to address treatment noncompliance. In order for MI to become standard nursing practice, a method of education must be developed and implemented. This necessitates the identification of effective education delivery methods. A staff education project was …

Predicting Seizure Onset Zones From Interictal Intracranial Eeg Using Functional Connectivity And Machine Learning, Jared Pilet, Scott A. Beardsley, Chad Carlson, Christopher T. Anderson, Candida Ustine, Sean Lew, Wade Mueller, Manoj Raghavan

Biomedical Engineering Faculty Research and Publications

Functional connectivity (FC) analyses of intracranial EEG (iEEG) signals can potentially improve the mapping of epileptic networks in drug-resistant focal epilepsy. However, it remains unclear whether FC-based metrics provide additional value beyond established epilepsy biomarkers such as epileptic spikes and high-frequency oscillations (HFOs). Using interictal iEEG data from 26 patients, we estimated FC across eight frequency bands (4–290 Hz) using amplitude envelope correlation (AEC) and phase locking value (PLV). From the resulting FC-matrices, we estimated two graph metrics each to derive 32 FC-based features. We also extracted features related to spikes, HFOs, and power spectral densities (PSD). A trained support …

Department of Biochemistry and Molecular Biology Faculty Papers

N 6-Methyladenosine (m6A), the most abundant modification in eukaryotic messenger RNAs (mRNAs), has also been found at a low level in bacterial mRNAs. However, enzyme(s) that introduce m6A modification on mRNAs in bacteria remain elusive. In this work, we combine deep-sequencing approaches that identify m6A sites with in vitro biochemical studies to identify putative m6A methyltransferases that would modify Escherichia coli mRNAs. We tested four uncharacterized candidates predicted to encode proteins with putative methyltransferase domains, whose deletion decreased the m6A level. However, in vitro analysis with the purified putative methyltransferases revealed that none of them installs m6A on mRNA. Exposure …

Psychology Faculty Publications and Presentations

Early widowhood is characterized by chronic stress and is associated with a higher risk of incident depression and cardiovascular-related morbidity and mortality. Peripheral inflammation is involved in the pathogenesis of major depressive disorder and atherothrombosis and may represent a common mechanism underlying widow(er)'s elevated risk for both health conditions. Chronic psychological stress sensitizes the release of proinflammatory cytokines during the peripheral stress response. The present study examined whether recent spousal bereavement enhances the inflammatory response to an acute, psychological stressor. Recently widowed older adults (n = 143) and non-widowed controls (n = 69) participated in a quasi-experimental study, during which …

2020-Current year OA Pubs

Subcortical brain structures such as the subthalamic nucleus or the thalamus are involved in regulating motor and cognitive behavior. However, their contribution to perceptual consciousness remains unclear, due to the inherent difficulties of recording subcortical neuronal activity in humans. Here, we asked neurological patients undergoing surgery for deep brain stimulation to detect weak vibrotactile stimuli applied on their hand while recording single neuron activity from the tip of a microelectrode. We isolated putative single neurons in the subthalamic nucleus and thalamus. A significant proportion of neurons modulated their activity while participants were expecting a stimulus. We found that the firing …

Leveraging Ai For Marketing Decisions: Algorithmic Targeting And Healthcare Applications, Annie Shi May 2025

Leveraging Ai For Marketing Decisions: Algorithmic Targeting And Healthcare Applications, Annie Shi

Olin Business School Graduate Student Theses and Dissertations

In this dissertation, I leverage artificial intelligence (AI) for making effective marketing decisions, specifically on how to measure the causal effects of targeting promotions and detecting suspicious retail buyers of opioids. In the first chapter, we propose a novel approach in measuring the true causal effects of targeting promotions. Targeting promotions on online platforms are often determined by AI algorithms, which utilize extensive customer and seller information to generate various algorithmic scores for targeting. Effective targeting, however, will lead to selection bias when evaluating the causal effects of promotions. we analyzed 2,294 promotion experiments on a major online retail platform …

It Is Not Clear How Well Physical Activity Promotion Materials Are Understood: Findings From A Rapid Literature Review, Jafra D. Thomas, Jasmine C. Wong, Regina F. Hockert, Yi Sheng Wu, Winston Kennedy

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 6: Issue 1, Article 6, 2025. Efforts to promote physical activity and other health-related behaviors are more effective when resource materials are understood by a wide and diverse audience. Before our lab’s previous investigations (Thomas et al., 2024), only one study seemed to use the cloze procedure to directly test the comprehension (i.e., readability) of physical activity promotion material (Cardinal & Seidler, 1995). Thus, this rapid literature review sought to (a) determine the extent the cloze procedure has been used to study physical activity promotion material comprehension in lay adults and (b) collate …
