Metabolic Scaling, Energy Allocation Tradeoffs, And The Evolution Of Humans’ Unique Metabolism, Andrew K. Yegian, Steven B. Heymsfield, Eric R. Castillo, Manfred J. Müller, Leanne M. Redman, Daniel E. Lieberman

Clinical Research Faculty Publications

All organisms use limited energy to grow, survive, and reproduce, necessitating energy allocation tradeoffs, but there is debate over how selection impacted metabolic budgets and tradeoffs in primates, including humans. Here, we develop a method to compare metabolic rates as quotients of observed relative to expected values for mammals corrected for size, body composition, environmental temperature, and phylogenetic relatedness. Contrary to previous analyses, these quotients reveal that nonhuman primates have total metabolic rates expected for similar-sized mammals in similar environments. In addition, data from several small-scale societies show that humans evolved exceptionally high resting, activity, and total metabolic rates apparently …

Mobilizing The Masks Of Carnaval For A Re-Reading Of Zobel's Rue Cases-Nègres, Benjamin E. Tilson

Tête à Tête: Journal of Francophone Studies

The identity of Caribbean literature, subject to the forces of domination and exclusion, has long been contested from both within and outside of its field. Alternately described as imitating, reappropriating, indigenizing and reductionist, Caribbean writers have sought to carve out a space for works that are received as authentic without recourse to fetishes. Drawing upon the works of Maryse Condé, the Creolists and anthropologic studies of Carnaval, the present work attempts to analyze what might be termed alternative narratives, characters and symbols in Joseph Zobel’s novel La Rue Cases-Nègres and its filmic adaptation by Euzhan Palcy through the lens of …

This research investigates geomorphic changes to the Mississippi-Alabama-Florida (MAFLA) sand sheet, which presents as shore-oblique Holocene sand ridges, and the exposure and burial of tree stumps following the passage of Hurricane Sally in 2020 using repeat sidescan and bathymetric …

Intensification Strategies Of Southern Arizona Bilinguals, Sadie E. Seilhan

LSU Master's Theses

The present thesis explores the intensification strategies employed by bilingual Spanish-English speakers in Southern Arizona, focusing on six distinct devices: lexical, phrasal, repetition, reformulation, hyperbole, and code-switching. While previous research has largely centered on adverbial and lexical intensifiers in monolingual contexts, this study broadens the scope by examining how bilingual speakers leverage their unique linguistic repertoire to amplify their speech. Using a sociopragmatic framework, the analysis reveals a marked preference for lexical intensification, which accounts for more than half of the recorded instances, with phrasal intensification and repetition following closely. Despite its lower frequency, code-switching stands out as a particularly …

Martial Spirits And Marital Rites: Assessing Rousseau's Critique Of Commerce's Devaluation Of The Military And The Family, Jacob A. Harvey

LSU Doctoral Dissertations

This dissertation will investigate Rousseau’s critique of how commercial society devalues soldiers and families and the responses provided by defenders of commerce. I will examine Rousseau’s corpus to demonstrate how Rousseau viewed commerce as a threat to both the responsibilities that men in a political community must be willing to fight and die for their country, as commercial societies intensify the hedonistic risk-averse calculations within members of the community. I will also show how Rousseau’s concerns towards commerce extended to the family, inhibiting the joys that can come with being part of a family and inhibiting citizens' willingness to have …

We review the functioning and sustainability of coastal marshes and mangroves. Urbanized humans have a 7,000-year-old enduring relationship to coastal wetlands. Wetlands include marshes, salt flats, and saline and freshwater forests. Coastal wetlands occur in all climate zones but are most abundant in deltas. Mangroves are tropical, whereas marshes occur from tropical to boreal areas. Quantification of coastal wetland areas has advanced in recent years but is still insufficiently accurate. Climate change and sea-level rise are predicted to lead to significant wetland losses and other impacts on coastal wetlands and the humans associated with them. Landward migration and coastal retreat …

Spatiotemporal Climatology Of Georgia Tropical Cyclones And Associated Rainfall, Reilly Corkran, Jill Trepanier, Vincent Brown

Faculty Publications

Tropical cyclones (TCs), often characterized by high wind speeds and heavy rainfall, cause widespread devastation, affecting millions of people and leading to economic losses worldwide. TC-specific research in Georgia is scarce, likely due to the minimal geographical extent of its coast and the infrequency of direct landfalls. Research on Georgia TCs does not account for storms that make landfall in other southeastern states (e.g., Florida) and continue north, northeast, or northwest into Georgia. This study used the North Atlantic Basin hurricane database (HURDAT2) to quantify the spatiotemporal patterns of direct and indirect landfalling of Georgia tropical cyclones (>16 ms−1) …

Scene Classification Of Remote Sensing Image Based On Multi-Path Reconfigurable Neural Network, Wenyi Hu, Chunjie Lan, Tian Chen, Shan Liu, Lirong Yin, Lei Wang

Faculty Publications

Land image recognition and classification and land environment detection are important research fields in remote sensing applications. Because of the diversity and complexity of different tasks of land environment recognition and classification, it is difficult for researchers to use a single model to achieve the best performance in scene classification of multiple remote sensing land images. Therefore, to determine which model is the best for the current recognition classification tasks, it is often necessary to select and experiment with many different models. However, finding the optimal model is accompanied by an increase in trial-and-error costs and is a waste of …

The southeastern United States Coastal Plain ecosystem contains baldcypress (Taxodium distichum) swamps and grass-dominated marshes. These ecosystems also occurred on the exposed continental shelf during lower sea levels but are rarely preserved due to the mechanically erosive nature of transgression and regression. Two presently marine sites on the northeastern Gulf of Mexico's continental shelf contain well-preserved woody terrestrial sediments that were the subject of previous studies. This study continues the investigation using geochemical (δ13C, δ15N, δ34S) and palynological characteristics of these formerly terrestrial sediments to determine if swamps and/or marshes existed at the time of deposition. The first site is …

No Evidence For Metabolic Adaptation During Exercise-Related Energy Compensation, E. W. Flanagan, G. Sanchez-Delgado, C. K. Martin, E. Ravussin, H. Pontzer, L. M. Redman

Clinical Research Faculty Publications

The constrained energy model posits that the increased total daily energy expenditure (TDEE) in response to exercise is often less than the energy cost of the exercise prescribed. The mechanisms behind this phenomenon, coined “exercise-related energy compensation” (ExEC), are poorly understood, and it is unknown if ExEC is coupled with metabolic adaptation. Using a randomized controlled 24-week exercise intervention, individuals who demonstrated ExEC were identified. Changes to all components of TDEE and metabolic adaptation were assessed using doubly labeled water over 14 days and room calorimetry over 24-h 48% of individuals exhibited ExEC (−308 ± 158 kcals/day). There were no …
