Meaning of Life Events and Person Characteristics Interactions Predicting Changes in Attachment
No full textThese are the slides from a presentation given at Society for Personality and Social Psychology Annual Convention on 02/22/2025.One of the core themes in Bowlby (1973)’s attachment theory is the extent to which people’s attachment (in) security exhibits stability and change over time. Previous research has identified life events that may predict such changes but focused on the objective occurrence of events, often overlooking individual subjective experiences. To address this gap, the study explored how people’s subjective interpretations of 7 life events and the interaction between 10 personal characteristics and these experiences (P x sE) relate to changes in their attachment (in)security over time. We analyzed data from 6566 adults who completed between 1 and 24 monthly survey assessments. Our results suggested that the frequency and nature of person-by-subjective experience (P x sE) interactions differed in meaningful ways across specific life events and person characteristics. Additionally, it highlighted that individuals’ subjective interpretations of life events may be a stronger predictor of change in state attachment (in) security than the objective occurrence of events, and offered new insights into why individuals’ sense of security may change in different ways over time
PNIPAM-based Polymers with Selective Absorption for Polar Liquid from Non-Polar Liquid
No full textThese are the slides from a presentation given at National Graduate Research Polymer Conference on 03/20/2025.Separating miscible liquids is an important step in various processes such as wastewater treatment, pharmaceutical engineering, petrochemical product refining, and the food and beverage industry. The current distillation method is limited due to its high energy consumption and lack of ability to separate azeotropes. Herein. we report a poly(n-isopropyl acrylamide) (PNIPAM)-based polymer that demonstrates selective absorption for ethanol from n-heptane. This was verified by refractive index measurements of the feed mixture and the retentate after absorption experiments. Furthermore, PNIPAM copolymerized with fluorinated acrylate (f-PNIPAM). F-PNIPAM exhibited more ethanol absorption which can be attributed to a lowered affinity to n-heptane. These results suggest the potential of the proposed material and mechanism to substitute the distillation method
Narrative Strategies in Social Media Marketing: Case Study in First-Generation Personal Finance Advice on Instagram
No full textThese are the slides from a presentation given at AMA Winter Academic Conference on 02/14/2025.Technology can exacerbate economic inequity through a digital divide, but digital and social media can also level the information access playing field for important decisions, such as personal finance. This study uses Social Support Theory (SST) to explore narrative strategies in Instagram personal finance content created by and targeted to first-generation college graduates. A qualitative case study examined financial advice designed for this understudied population. The content offered a strong asset-based orientation focused on the skills, abilities, and cultural wealth fellow first-generation college graduates leverage. Social support is evident through widespread use of specific emotional, informational, and appraisal support
Disempowering Language in Online Patient Education Materials for People with Type 1 Diabetes: Progress on a Summative Content Analysis
No full textThis poster was presented on April 2, 2025 at The Institute for Public Health and Medicine's Public Health Summit 2025, held at the Northwestern Feinberg School of Medicine, Robert H. Lurie Medical Research Center, Chicago, IL.Objectives: Type 1 diabetes (T1D) is a complex chronic disease requiring ongoing self-management. Patient education aims to empower people to set goals and choose behaviors that accommodate patients’ lives and support optimal health outcomes. The use of disempowering language, however, can undermine self-management and psychosocial outcomes. Disempowering language includes stigmatizing, blaming, and condition-first words or phrases. The objective of this study is to assess T1D online patient education materials (PEMs) for the presence of disempowering language using summative content analysis. This poster reports the sampling protocol and data collection from Phase 1 of the content analysis.
Methods: Summative content analysis quantifies word frequencies (Phase 1) and explores the context of usage (Phase 2). We developed, tested, and refined a sampling protocol for Phase 1. Included PEMs were publicly available, specific to T1D, intended as patient education, available for download, and relevant to newly diagnosed patients. Advertisements, multimedia, resource lists, and manuals were excluded. Disempowering terms and term categories were selected from published diabetes language guidelines. The term categories included Control, Diabetic, Imperatives, Prevent, and Test. Voyant Tools was used to identify the disempowering terms within each PEM. A data collection tool was designed and used to measure how frequently terms were used in each PEM.
Results: Results of the sampling protocol produced 255 unique online PEMs from six Google search strings used to harvest the sample. Each PEM was screened by two independent researchers and variances were resolved by a third researcher. Twenty-nine PEMs were identified for inclusion. All PEMs in the sample used disempowering terms. The highest frequency was in the term category, Imperatives, representing 54% of the total number of disempowering terms used in the sample. Analysis of the results is ongoing.
Conclusions: The refined sampling protocol produced a small but robust data set of unique online PEMs representative of freely available materials patients would encounter online, when searching for general diagnosis information about T1D. The data collection tool used to measure the frequency of disempowering terms in the sample was effective, identifying disempowering terminology use across the sample. Disempowering terms from the data collection tool will be further assessed in Phase 2, which will contextualize the use of those terms and similarly identified words and phrases
Interned Japanese-American Women’s Aspirations for Independence
No full textThese are the slides from a presentation given at 2025 Midwest Sociological Society Annual Meeting on 03/16/2025.This study examines letters exchanged between Japanese-American women and Clara Breed, the librarian at the San Diego Public Library from 1929 to 1945, who became a reliable correspondent, sending care packages that included books, daily necessities, and school supplies. Most of these letters were composed by women and young children, reflecting their perspectives on the challenges they faced, including isolation, uncertainty, and the struggle to maintain a sense of normalcy in the camps. This essay explores how life in these camps influenced Japanese-American women’s independence and motivated their pursuit of academic degrees and careers. Analyzing the letters in the collection, this research reveals the profound impact of internment on women's roles and aspirations. Notably, the letters convey their desires for self-determination and professional growth, as many women began to articulate their ambitions amid oppressive conditions. Conducting research on the origins of Japanese American women’s independence raises essential questions: How did life in the camps help these women achieve independence, and how did it lead them to demand academic degrees or pursue careers? Exploring these questions not only highlights the positive functions of internment camps on Japanese American women’s lives but also has the potential to connect this history to broader narratives of gender activism
PfCSP-Ferritin Nanoparticle Malaria Vaccine Antigen Formulated with Aluminum-salt and CpG 1018® Adjuvants: Preformulation Characterization, Antigen-Adjuvant Interactions, and Mouse Immunogenicity Studies (Dataset)
No full textCircumsporozite protein (CSP), the most abundant surface protein on the parasitic Plasmodium falciparum (Pf) sporozoite and an attractive target for malaria vaccine design, has been shown to induce protective humoral response in humans. In this work, we characterized and formulated a promising recombinant PfCSP immunogen (155) candidate consisting of two PfCSP epitopes (i.e., junction, NANP repeat) fused to H. pylori apoferritin forming a 24-mer nanoparticle. In addition, two N-linked glycans were engineered to mitigate possible anti-apoferritin immune responses and a universal T-cell epitope was included to further enhance immunogenicity. Physicochemical characterization of the 155 antigen was performed including primary structure, post-translational modifications, conformational stability, and particle size. A competitive ELISA was developed to assess antigen binding to a PfCSP-specific mAb. The in vitro antigenicity of the 155 antigen was measured upon formulation with adjuvants, including aluminum-salts (i.e., AlhydrogelTM, Adju-PhosTM) and the TLR-9 agonist CpG 1018®, when freshly combined and after storage at different temperatures over 3 months. The in vivo immunological impact of various adjuvanted formulations of the 155 antigen was investigated in mice. The results support formulation of 155 with AlhydrogelTM + CpG 1018® adjuvants as a promising recombinant malaria vaccine candidate from both a pharmaceutical and immunological perspective
Photoredox-Catalyzed Decarboxylative Elimination via Halogen-Atom Transfer
No full textThese are the slides from a presentation given at ACS Spring 2025 on 03/27/2025.
.
.Enamines are valuable nucleophilic reagents, but their propensity to undergo hydrolysis limits their use in organic synthesis. However, enamides and enecarbamates offer an excellent balance between stability and reactivity. Classically, the synthesis of these moieties requires hazardous chemicals like Grignard reagents and azides or involves the production of toxic waste by-products such as sulfur dioxide. On the other hand, decarboxylation of widely available amino acids offers a green and efficient way for their synthesis. However, the reported procedures suffer from drawbacks such as pre-activation of amino acids or moderate E/Z ratios. Therefore, the present study describes a transition metal-free, photocatalytic approach for the direct decarboxylative synthesis of enamides via halogen-atom transfer. The utility of this new method was demonstrated by synthesizing thirty-six enamides and enecarbamates from various amino acids and dipeptides. Results of scalability studies and downstream derivatization of the substrates will be presented. Finally, current mechanistic understanding of the reaction will be expounded
Inferring corporate insiders’ beliefs about firm value from tax withholding elections
No full textThis presentation was given on November 22, 2024 at the Southern Finance Association Annual Meeting.Exploiting tax withholding elections around equity compensation transactions, we find that tax withholding predicts annualized next month returns that are 4% – 8% lower than not withholding. Withholding is more informative in the presence of greater information asymmetry and following personal tax rate changes. Examining the extent to which withholding reflects opportunism, we find that, during blackout trading periods, withholdings are more likely to occur and more predictive of earnings announcement surprises than sales. Insiders eventually sued by the SEC change their election choice more frequently, and the informativeness of withholding is lower in the year of an SEC enforcement action
A Pilot Study of “Help for Overcoming Problem Eating” (HOPE): A Single Session Intervention for College Students with Binge-Spectrum Eating Disorders
No full textThis poster was presented at Eating Disorder Research Society on 09/26/2024.Introduction: Eating disorders (EDs) are common among college students with approximately 30% of college students endorsing binge eating. Yet, most students with binge-spectrum EDs do not have access to care on their campus. Single Session Interventions (SSIs) can help increase access-to-care for college students with EDs. The goal of this ongoing study was to test the acceptability of Help for Overcoming Problem Eating (HOPE), the first mobile health application based SSI designed to reduce binge eating in college students. HOPE aimed to increase regular eating, an evidence-based technique that has demonstrated effectiveness in reducing binge eating. Methods: College students (N=36) with non-low-weight binge-spectrum EDs completed HOPE and rated its acceptability and useability. Participants also completed a measure of binge eating at baseline and one-week follow-up. Preliminary Results: Paired sample t-tests showed that participants had significant reduction in binge eating at one-week follow-up. Participants found HOPE to be highly acceptable, with a mean overall score of 4.12/5. Qualitative feedback suggested that participants understood the rationale behind regular eating and were motivated to engage in regular eating to reduce binge eating. Conclusion: Results demonstrate preliminary feasibility and acceptability of HOPE. HOPE shows initial promise of helping reduce the public-health burden of EDs in college students by improving accessibility and scalability of care
