Valuing The Negative Impacts Of Harmful Algae Blooms, Sergio Alvarez

Rosen Research Review

Ecological disturbances can impact several ecosystem services, including cultural services such as outdoor recreation opportunities. In Florida, one ecological disturbance that is negatively impacting recreation is the occurrence of harmful algae blooms. In recent work, Dr. Sergio Alvarez at UCF Rosen College of Hospitality Management has assessed the impact that harmful algae blooms have on human wellbeing by using random utility models to estimate changes in the value of recreation in coastal ecosystems resulting from these blooms. The results indicate that harmful algae blooms, which reduced boating access between June and September 2018, may have resulted in losses of up …

Determinants Of Fine-Scale Heterogeneity In Mosquito-Borne Virus Systems, Elizabeth Handly Mayton

LSU Doctoral Dissertations

ABSTRACT

Arthropod-borne viruses (arboviruses) are the etiological agents of much morbidity and mortality, especially in low- and middle-income countries. Many of these viruses are spread and maintained by mosquitoes, particularly the urban mosquito Aedes aegypti. Zika virus (ZIKV) is responsible for one of the largest vector-borne disease outbreaks in the past decade, affecting millions in Central and South America including a wave of microcephaly among newborns. Mayaro virus (MAYV) is a mosquito-borne virus endemic to South America and is predicted to become an emergent public health threat. Describing the vector-virus transmission systems are critical for understanding the potential spread …

Challenging The Illusion Of Diversity: A New Theoretical Paradigm Towards Newsroom Inclusion., Paromita Saha

LSU Doctoral Dissertations

Over the past forty years, the news industry has attempted to diversify the racial composition of their newsrooms from the perspective of representing their markets better mirroring best business practices in the industry. The statistics show that an affirmative style of recruitment has produced minimal, superficial results with a high turnover of minority journalists who are hardly promoted to editorial positions, as well as skewed representations of minority racial groups. The literature indicates that hegemonic ideological forces and the White male professional ethos behind journalism is not conducive to minority journalists producing meaningful changes to news content. My study indicates …

Degumming Of Hemp Fibers Using Combined Microwave Energy And Deep Eutectic Solvent, Bulbul Ahmed

LSU Master's Theses

Hemp is considered as one of the sustainable agricultural fiber materials. Degumming or surface modification of hemp bast is needed to produce single fibers for ensuing textile and industrial applications. The traditional degumming process necessitates a high amount of alkali, which causes detrimental environmental pollution. This study offers a new method to degum hemp fibers with reduced use of harmful alkali and precious water resources. In this work, hemp bast fibers were degummed by using combined microwave energy and deep eutectic solvent (DES). The properties of hemp fibers manufactured by this method were investigated and compared with the traditional alkali …

Bcr Affinity Influences T-B Interactions And B Cell Development In Secondary Lymphoid Organs, Alec J. Wishnie, Tzippora Chwat-Edelstein, Mary Attaway, Bao Q. Vuong

Publications and Research

B cells produce high-affinity immunoglobulins (Igs), or antibodies, to eliminate foreign pathogens. Mature, naïve B cells expressing an antigen-specific cell surface Ig, or B cell receptor (BCR), are directed toward either an extrafollicular (EF) or germinal center (GC) response upon antigen binding. B cell interactions with CD4+ pre-T follicular helper (pre- Tfh) cells at the T-B border and effector Tfh cells in the B cell follicle and GC control B cell development in response to antigen. Here, we review recent studies demonstrating the role of B cell receptor (BCR) affinity in modulating T-B interactions and the subsequent differentiation of B …

Morphology Transformation Of Foldamer Assemblies Triggered By Single Oxygen Atom On Critical Residue Switch, Byung-Chang Oh, Eunyoung Yoon, Jintaek Gong, Jaewook Kim, Russell W. Driver, Yongjun Kim, Woo Youn Kim, Hee-Seung Lee

Chemistry and Physics Faculty Articles

The synthesis of morphologically well-defined peptidic materials via self-assembly is challenging but demanding for biocompatible functional materials. Moreover, switching morphology from a given shape to other predictable forms by molecular modification of the identical building block is an even more complicated subject because the self-assembly of flexible peptides is prone to diverge upon subtle structural change. To accomplish controllable morphology transformation, systematic self-assembly studies are performed using congener short β-peptide foldamers to find a minimal structural change that alters the self-assembled morphology. Introduction of oxygen-containing β-amino acid (ATFC) for subtle electronic perturbation on hydrophobic foldamer induces a previously inaccessible solid-state …

Stress-Induced Plasma Cortisol Concentrations In Infancy Are Associated With Later Parenting Behaviors In Female Rhesus Macaques (Macaca Mulatta), Colt Halter

Undergraduate Honors Theses

Few studies have longitudinally assessed the relationship between infant stress reactivity and future parenting styles. Stress-induced plasma cortisol concentrations are stable over development and can be utilized as a marker for stress reactivity. This study investigates the relationship between stress-induced plasma cortisol concentrations in infancy and later parenting behavior in a translational nonhuman primate model. We hypothesized that higher stress-induced cortisol levels in infancy would predict impairments in maternal behaviors in adulthood. Subjects were rhesus macaque females (N=122; Macaca mulatta), assessed as infants and again as mothers. At three-to-four months of age, subjects underwent a standardized BioBehavioral …

Timing Of Childhood Adversities And Self-Injurious Thoughts And Behaviors In Adolescence, Samantha J. North, Kathryn R. Fox, Jenalee R. Doom

Graduate School of Professional Psychology: Faculty Scholarship

Greater childhood adversity predicts a higher likelihood of later self-injurious thoughts and behaviors (SITB). There is little research focused on whether the timing of childhood adversity predicts SITB. The current research examined whether the timing of childhood adversity predicted parent- and youth-reported SITB at age 12 and 16 years in the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) cohort (n = 970). We found that greater adversity at age 11–12 years consistently predicted SITB at age 12 years, while greater adversity at age 13–14 years consistently predicted SITB at age 16 years. These findings suggest there may be sensitive …

Potential Benefits Of Bovine Colostrum In Pediatric Nutrition And Health, Per Torp Sangild, Caitlin Vonderohe, Valeria Melendez Hebib, Douglas G Burrin

Children’s Nutrition Research Center Staff Publications

Bovine colostrum (BC), the first milk produced from cows after parturition, is increasingly used as a nutritional supplement to promote gut function and health in other species, including humans. The high levels of whey and casein proteins, immunoglobulins (Igs), and other milk bioactives in BC are adapted to meet the needs of newborn calves. However, BC supplementation may improve health outcomes across other species, especially when immune and gut functions are immature in early life. We provide a review of BC composition and its effects in infants and children in health and selected diseases (diarrhea, infection, growth-failure, preterm birth, necrotizing …

Reduced Fecundity In Free-Ranging Norway Rats After Baiting With A Liquid Fertility Control Bait, Gary W. Witmer, Stefanie Raymond-Whish

Human–Wildlife Interactions

Norway rats (Rattus norvegicus) cause extensive crop loss, infrastructure damage, and are vectors for zoonotic diseases. Due to reduced efficacy, environmental and animal welfare concerns related to traditional pest management tools, such as rodenticides, it is imperative to find new methods for controlling commensal rodents. Fertility control is emerging as a safe, humane, and effective method of long-term population management. Vinylcyclohexene diepoxide (VCD) and triptolide are 2 compounds that are known to target and inhibit ovarian function. Furthermore, triptolide debilitates spermatogenesis and sperm motility. We prepared liquid bait containing no active ingredients (control) or containing VCD (0.098%) and …
