Digital Discrimination In The Sharing Economy: Evidence, Policy, And Feature Analysis, Miroslav Tushev Mar 2022

Digital Discrimination In The Sharing Economy: Evidence, Policy, And Feature Analysis, Miroslav Tushev

LSU Doctoral Dissertations

Applications (apps) of the Digital Sharing Economy (DSE), such as Uber, Airbnb, and TaskRabbit, have become a main facilitator of economic growth and shared prosperity in modern-day societies. However, recent research has revealed that the participation of minority groups in DSE activities is often hindered by different forms of bias and discrimination. Evidence of such behavior has been documented across almost all domains of DSE, including ridesharing, lodging, and freelancing. However, little is known about the under- lying design decisions of DSE systems which allow certain demographics of the market to gain unfair advantage over others. To bridge this knowledge …


Evaluation Of Hippocampal Allostatic Load-Associated Factors In Animal Models Of Post-Traumatic Stress Disorder: Relevance To Human Ptsd, Dennis Parker Kelley Mar 2022

Evaluation Of Hippocampal Allostatic Load-Associated Factors In Animal Models Of Post-Traumatic Stress Disorder: Relevance To Human Ptsd, Dennis Parker Kelley

LSU Doctoral Dissertations

Post-traumatic stress disorder (PTSD) is associated with elevated allostatic load, nearly double the risk for metabolic syndrome, reduced hippocampal volume, and contextual memory processing deficits. Emerging evidence suggests that these stress effects may predispose individuals to the development of PTSD, and there is a known relationship between chronic stress and metabolic dysfunction. In this work, we utilized two rat models of PTSD to explore these connections. We used an acute predator odor stressor to investigate the relationship between PTSD-like behaviors and mitochondrial dysfunction in the hippocampus of rats, and we observed that conditioned place avoidance was associated with reduced mitochondrial …

Impact Of Host Plant Resistance On Emergence, Body Parameters, And Supercooling Point Of Cylas Formicarius Elegantulus (Coleoptera: Brentidae), Nupur Sarkar, Mark J. Murray, Michael J. Stout, Jeffrey A. Davis

Faculty Publications

Sweetpotato weevil, Cylas formicarius elegantulus (Summers) (Coleoptera: Brentidae), an in-field and storage pest of sweetpotato, is the primary insect constraint to sweetpotato production in tropical and subtropical regions. Feeding by adult and larval sweetpotato weevil induces terpenes, rendering storage roots unmarketable. To reduce storage root damage and sweetpotato weevil populations, the present experiment tested the impact of sweetpotato cultivar on developmental time, adult emergence, body length, weight, and supercooling point of sweetpotato weevil. The cultivars tested were â Beauregard' and â Evangeline,' both orange fleshed cultivars susceptible to sweetpotato weevil, and â Murasaki,' a white fleshed cultivar known to be …


A Comparison Of Hay And Fish Emulsion-Infused Water As Oviposition Attractants For The Cdc Gravid Trap, Timothy D. Mcnamara, Kristen Healy Mar 2022

A Comparison Of Hay And Fish Emulsion-Infused Water As Oviposition Attractants For The Cdc Gravid Trap, Timothy D. Mcnamara, Kristen Healy

Faculty Publications

Multiple oviposition attractants are used for Culex (Diptera: Culicidae) mosquito surveillance in the CDC Gravid Trap, including hay and fish emulsion-infused water. Despite the use of both in the United States, no research has compared their attractiveness. We conducted trapping throughout Louisiana to assess the attractiveness of hay and fish emulsion-infused water in various habitat types and climates. Our results indicate that fish emulsion-infused water attracts more mosquitoes overall, more Culex quinquefasciatus (Say, 1823), and a wider diversity of mosquitoes than hay-infused water. This trend was maintained, regardless of habitat type or climate.

Division of Basic Science Faculty Publications

The mediator kinase module plays a critical role in the regulation of transcription during metabolic processes. Here we demonstrate that in human adipose-derived stem cells (hASCs), kinase module subunits have distinct mRNA and protein expression profiles during different stages of adipogenesis. In addition, siRNA-mediated loss of MED12 results in decreased adipogenesis as evident through decreased lipid accumulation and decreased expression of PPARγ, a master regulator of adipogenesis. Moreover, the decrease in adipogenesis and reduced PPARγexpression are observed only during the early stages of MED12 knockdown. At later stages, knockdown of MED12 did not have any significant effects on adipogenesis or …

The Counterbalancing Effects Of Energy Expenditure On Body Weight Regulation: Orexigenic Versus Energy-Consuming Mechanisms, Paolo Piaggi, Alessio Basolo, Corby K. Martin, Leanne M. Redman, Susanne B. Votruba, Jonathan Krakoff

Clinical Research Faculty Publications

Objective: Weight change is a dynamic function of whole-body energy balance resulting from the interplay between energy intake and energy expenditure (EE). Recent reports have provided evidence for the existence of a causal effect of EE on energy intake, suggesting that increased EE may drive overeating, thereby promoting future weight gain. This study investigated the relationships between ad libitum energy intake and 24-hour EE (24-h EE) in sedentary conditions versus long-term, free-living weight change using a mediation analysis framework. Methods: Native American individuals (n = 61, body fat by dual-energy x-ray absorptiometry: 39.7% [SD 9.5%]) were admitted to the clinical …

Post-Acute Sequelae Of Covid-19: A Metabolic Perspective, Philipp E. Scherer, John P. Kirwan, Clifford J. Rosen

Division of Basic Science Faculty Publications

The SARS-CoV-2 pandemic continues to rage around the world. At the same time, despite strong public health measures and high vaccination rates in some countries, a post-COVID-19 syndrome has emerged which lacks a clear definition, prevalence, or etiology. However, fatigue, dyspnea, brain fog, and lack of smell and/or taste are often characteristic of patients with this syndrome. These are evident more than a month after infection, and are labeled as Post-Acute Sequelae of CoV-2 (PASC) or commonly referred to as long-COVID. Metabolic dysfunction (i.e., obesity, insulin resistance, and diabetes mellitus) is a predisposing risk factor for severe acute COVID-19, and …
