Perspectives Of Probation Officers On Training To Support Women Who Commit Co-Occurring Crimes, Cynthia Stephens Apr 2025

Perspectives Of Probation Officers On Training To Support Women Who Commit Co-Occurring Crimes, Cynthia Stephens

Walden Dissertations and Doctoral Studies

The lack of understanding about probation officers’ (POs’) training views, especially concerning female offenders, reduces training and reentry effectiveness for female criminals. This study investigated POs’ perspectives on their training to assist women with co-occurring offenses by developing a practical intervention framework to improve reentry outcomes. The labeling and dual-role relationship theories served as the theoretical foundation to answer the research question, which involved identifying the perspectives of POs on training to support women with co-occurring crimes. A phenomenological design and in-depth face-to-face PO interviews were appropriate to answer the research question. Thematic analysis occurred to identify key concepts revealed …

Understanding Strain-Level Dynamics In Gut Commensal-Pathogen-Host Interactions, Anna Louise Deveaux Apr 2025

Understanding Strain-Level Dynamics In Gut Commensal-Pathogen-Host Interactions, Anna Louise Deveaux

Arts & Sciences Graduate Student Theses and Dissertations

The human gut microbiome is a consortium of trillions of bacteria, archaea, fungi, and viruses that colonizes the gastrointestinal tract and promotes health under homeostatic conditions. This microbial community trains the immune system, modulates inflammation and anticancer immunity, promotes cardiometabolic health, enables nutrient extraction, and prevents pathogen overgrowth. The latter function manifests through colonization resistance, in which microbes occupy spatial and nutritional niches thereby excluding pathogens from the community entirely, and through limiting pathogen population growth if colonization occurs. These roles are facilitated by complex host-microbe and microbe-microbe interactions that underlie differences in susceptibility to microbiome-mediated infectious diseases. The strain-level …


A Woman's Place In Politics: The Effects Of Gendered Politics On A Global Level, Aruhi Kodeboyina Apr 2025

A Woman's Place In Politics: The Effects Of Gendered Politics On A Global Level, Aruhi Kodeboyina

Undergraduate Student Symposium

Women have been denied equality, especially with respect to their male counterparts. Feminism is the theory that seeks to explain this by the norms, beliefs, and societal pressure by which women have been excluded. One predominant realm in which women have been excluded is politics. Although there has been a rise in female politicians across the world, they continue to face the same stereotypes as before. Thus, this study delves into the implications of having more female leaders, looking more specifically at liberal feminist international relations theory. By reviewing literature, this study finds that female leaders impact a variety of …


Assessing The Gaps Between Ethnic Populations: A Comparison Of Lipid-Lowering Interventions ​, Chasen Hershman, Gavin Lamott, Chester Dejong Md Apr 2025

Assessing The Gaps Between Ethnic Populations: A Comparison Of Lipid-Lowering Interventions ​, Chasen Hershman, Gavin Lamott, Chester Dejong Md

Celebration of Research

Pharmacological and lifestyle interventions have been a proven strategy for lowering the cardiovascular risk in all populations. Despite this, certain ethnic populations have a greater ASCVD risk due to either high LDL levels or other factors. The goal of this review is to analyze variables (specifically LDL) that contribute to certain ethnic populations demonstrating a greater risk of CVD as well as interventions that can improve outcomes. Treatment of hyperlipidemia requires a multifactorial approach which is tailored to the individual patients’ needs. Statins continue to be first-line pharmacological therapy for the treatment of lowering LDL. When combining a healthy diet …

Subcutaneous Infusions For Hydration And Nutrition, Bryn Hoekman, Kelsie Dulmes, Laci Van Hauen, Megan Vankalsbeek, Mikayla Johnson, Pam Hulstein

Celebration of Research

Subcutaneous (SC) infusions deliver fluids or medications into the body's fatty tissue using small needles. They are cost-effective, easy to use, comfortable, and carry a low risk of serious complications like infections. In hospital settings, IV access can be challenging, and oral fluid intake may be insufficient for proper hydration. Spencer Hospital was interested in the potential benefits of SC infusions and what population would benefit most. The purpose of this project was to examine SC infusions as an alternative for hydration when IV access is unavailable, focusing on pediatric, geriatric, and palliative population. It compared Hydration, nutrition status, and …

Growing The Good: A Communal Garden Case Study Among Marginalized, Rural Populations, Claire Barbier Apr 2025

Growing The Good: A Communal Garden Case Study Among Marginalized, Rural Populations, Claire Barbier

LSU Master's Theses

Community and Communal gardens (CG) have been documented as early as the late 1800s during periods of economic recessions and high food insecurity (The MIT Press Reader, 2022). However, C.G. adoption rates are expanding on a global scale as communities and municipalities see the potential for the tool to bring relief to environments in dire need of additional resources. Utilizing a communal garden can be used to address a surplus of systemic barriers a community faces; it has a significant opportunity to bring forth the interconnected tiers of public health altogether (Twiss et. al, 2003). Modernized C.G projects bring forth …


Oral Hygiene And Cardiovascular Health, Md. S. Zaman, S. M. Golam Alam, Mohammed S. Razzaque Apr 2025

Oral Hygiene And Cardiovascular Health, Md. S. Zaman, S. M. Golam Alam, Mohammed S. Razzaque

School of Medicine Publications

The human oral microbiome plays a vital role in maintaining oral and systemic health. This diverse microbial community includes over 700 bacterial species, some of which are implicated in developing systemic diseases, particularly cardiovascular diseases (CVDs). Research highlights a strong association between periodontal disease and increased cardiovascular risk, suggesting that good oral hygiene practices may reduce the incidence of CVDs. Porphyromonas gingivalis and Fusobacterium nucleatum drive chronic inflammation in periodontal disease; these bacteria can extend beyond the mouth and contribute to systemic inflammatory responses. The inflammatory factors, including C-reactive protein (CRP), interleukins (IL-1, IL-6), and tumor necrosis factor-alpha (TNF-α), damage …

Modeling The Cystic Fibrosis Intestinal Environment To Study Microbial Interactions, Kaitlyn Emma Barrack Apr 2025

Modeling The Cystic Fibrosis Intestinal Environment To Study Microbial Interactions, Kaitlyn Emma Barrack

Dartmouth College Ph.D Dissertations

The microbiome of the cystic fibrosis (CF) intestine is altered significantly in structure and function beginning in early life. Key taxa associated with health, digestion and immune-training are reduced in abundance, including but not limited to Bacteroides, Faecalibacterium, Akkermansia, Ruminococcus and other short-chain fatty acid producers. Conversely, there is an expansion of microbes with pathogenic potential, such as Escherichia, Veillonella, Pseudomonas and Staphylococcus. The shifts in microbiota composition direct community-wide changes with differences in beta diversity by genotype, whereby children with CF (cwCF) exhibit significantly different gut microbial compositions compared to nonCF children. Additionally, shifts in microbiota structure often …
