Farm Life In The Asset Economy: First-Generation Farmers And The Agrarian Question, Elizabeth Pickard

Theses - ALL

A massive transition of land ownership is currently underway in the U.S. as an increasing proportion of farmers near retirement age with no successor in place. The question of who will replace them has come to the fore as policy makers and food justice activists alike contemplate a shift to a more equitable and ecologically sustainable food system. Embracing a "beginning farmer theory of change," some scholars have called for an increase in the number of first-generation farmers to account for the labor- and knowledge-intensive methods required for agroecological production. Others have brought attention to the historical and ongoing racial, …

The actual crop evapotranspiration (ETa) was mapped in Google Earth Engine Evapotranspiration Flux, using the linear interpolation method in …

Seasonal Variation In The Feeding Ecology Of Yellowfin Tuna (Thunnus Albacares) From The Northern Gulf Of Mexico, Mitchell Shay Lovell

LSU Master's Theses

Highly migratory fishes (e.g., tunas, billfishes, and sharks) play a significant role in the structure and function of open-ocean ecosystems and a better understanding of the food web dynamics that support their populations is essential to improve management and conservation. Here, I use complementary approaches (stomach contents, DNA barcoding, & stable isotopes) to examine seasonal variability in the feeding ecology of sub-adult (70 – 100 cm; n = 371) and adult (100 – 160 cm; n = 206) yellowfin tuna (Thunnus albacares) from the northern Gulf of Mexico over a one-year period (April 2019 – March 2020). Stomach …

Promoting Population Health In Local Communities: Parental Perceptions Of An Embedded Movement And Physical Activity Program For A Preschool Population, Jennifer Hight, Shirley P. O'Brien, Colleen M. Schneck

The Open Journal of Occupational Therapy

Background: Many children reach kindergarten lacking age-appropriate motor skills because of a lack of access to early intervention services or a lack of continued early intervention beyond 3 years of age. Research suggests sedentary children become sedentary adults, which contributes to a growing population of unhealthy Americans with chronic health conditions, such as high blood pressure, diabetes, heart disease, and psychosocial difficulties. Parents often are not aware of the benefits of engaging in physical activity or possess a lack of awareness of their local resources. A community based preschool movement program was created to foster physical activity and promote …

Gut Integrity And Duodenal Enteropathogen Burden In Undernourished Children With Environmental Enteric Dysfunction, Zehra Jamil, Najeeha Talat Iqbal, Romana Idress, Zubair Ahmad, Kamran Sadiq, Junaid Iqbal, Sana Syed, Aneeta Hotwani, Furqan Kabir, Kumail Ahmed, Sheraz Ahmed, Fayyaz Umrani, Fatima Aziz, Adil Kalam, Syed Asad Ali

Department of Biological & Biomedical Sciences

Environmental enteric dysfunction (EED) is a subclinical condition of intestinal inflammation, barrier dysfunction and malabsorption associated with growth faltering in children living in poverty. This study explores association of altered duodenal permeability (lactulose, rhamnose and their ratio) with higher burden of enteropathogen in the duodenal aspirate, altered histopathological findings and higher morbidity (diarrhea) that is collectively associated with linear growth faltering in children living in EED endemic setting. In a longitudinal birth cohort, 51 controls (WHZ > 0, HAZ > -1.0) and 63 cases (WHZ< -2.0, refractory to nutritional intervention) were recruited. Anthropometry and morbidity were recorded on monthly bases up to 24 months of age. Dual sugar assay of urine collected after oral administration of lactulose and rhamnose was assessed in 96 children from both the groups. Duodenal histopathology (n = 63) and enteropathogen analysis of aspirate via Taqman array card (n = 60) was assessed in only cases. Giardia was the most frequent pathogen and was associated with raised L:R ratio (p = 0.068). Gastric microscopy was more sensitive than duodenal aspirate in H. pylori detection. Microscopically confirmed H. pylori negatively correlated with HAZ at 24 months (r = -0.313, p = 0.013). Regarding histopathological parameters, goblet cell reduction significantly correlated with decline in dual sugar excretion (p< 0.05). Between cases and controls, there were no significant differences in the median (25th, 75th percentile) of urinary concentrations (μg/ml) of lactulose [27.0 (11.50, 59.50) for cases vs. 38.0 (12.0, 61.0) for controls], rhamnose [66.0 (28.0, 178.0) vs. 86.5 (29.5, 190.5)] and L:R ratio [0.47 (0.24, 0.90) vs. 0.51 (0.31, 0.71)] respectively. In multivariable regression model, 31% of variability in HAZ at 24 months of age among cases and controls was explained by final model including dual sugars. In conclusion, enteropathogen burden is associated with altered histopathological features and intestinal permeability. In cases and controls living in settings of endemic enteropathy, intestinal permeability test may predict linear growth. However, for adoption as a screening tool for EED, further validation is required due to its complex intestinal pathophysiology.

Department of Paediatrics and Child Health

Introduction: Responsible for at least one in nine pediatric deaths, diarrheal diseases are the leading, global cause of death. Further abetted by improper antibiotic use in a hospital setting, children with acute watery diarrhea can see prolonged hospital stays, and unwanted adverse effects such as antibiotic resistance. Hence, this study is aimed to identify the association between antibiotic usage for the treatment of acute watery diarrhea in children, and the impact this line of management has on the duration of their hospital stay.
Methods: A retrospective review was conducted at the department of Pediatric of Aga Khan University Hospital (AKUH) …

Blood's Concentration Of Lead And Arsenic Associated With Anemia In Peruvian Children, Ana Maria Linares, Jason M. Unrine, Amanda Thaxton Wigging, Juan C. Tantalean, Vlad C. Radulescu

Nursing Faculty Publications

This exploratory, descriptive cohort study (N = 60) determined lead (Pb) and arsenic (As) blood concentrations in Peruvian children and their association with hematological parameters of iron-deficient anemia (IDA) and anthropometric measurement. The mean age of children was 10.8 months (SD = 4.7) and ranged from 3 to 24 months old. Anemia (Hb levels below 10.5 g/dL) was found in 20% of this cohort. Additionally, microcytosis (MCV < 70 fL) was present in 54%, and hypochromia (MCH < 23 pg) in 42% of the group of children. Chi-square analysis showed that 88% of the children with anemia also had microcytosis and hypochromia (p < 0.001). Pb and As were detected in 100% of the infants’ blood samples, and the concentrations were significantly higher in older infants than in younger ones. Pb and As were not associated with the sex, anthropomorphic parameters, or infant hemogram changes. Infants who received iron supplementation were 87% less likely to have low Hb compared with those who did not (OR = 0.13, 95% CI = 0.02–0.88, p = 0.04). Herbal tea intake was significantly associated with microcytosis and hypochromia. Our finding uncovered that hematological parameters for anemia are modified in Peruvian children with high levels of microcytosis …

The Waxing & Waning Of Informed Consent: Medical Assistance In Dying And The Question Of Advance Requests, Thomas B. Mcmorrow

Osgoode Hall Law Journal

This paper traces the impact of the principle of informed consent on Canadian legal developments in the area of advance directives, medical assistance in dying (MAID), and (where the two converge) advance requests in the context of MAID. I show how recognition of the principle of informed consent has not only served to justify developments in the law facilitating advance directives; it has also played an important role in justifying the legalization, under specific circumstances, of MAID. The paradigmatic case of informed consent is where a clearly competent, fully informed adult effectively communicates with their physician, contemporaneously to the administration …

Protistan Grazing Impacts Microbial Communities And Carbon Cycling At Deep-Sea Hydrothermal Vents, Sarah K. Hu, Erica L. Herrera, Amy R. Smith, Maria G. Pachiadaki, Virginia P. Edgcomb, Sean P. Sylva, Eric W. Chan, Jeffrey S. Seewald, Christopher R. German, Julie A. Huber

School of Earth, Environmental, & Marine Sciences Faculty Publications

Microbial eukaryotes (or protists) in marine ecosystems are a link between primary producers and all higher trophic levels, and the rate at which heterotrophic protistan grazers consume microbial prey is a key mechanism for carbon transport and recycling in microbial food webs. At deep-sea hydrothermal vents, chemosynthetic bacteria and archaea form the base of a food web that functions in the absence of sunlight, but the role of protistan grazers in these highly productive ecosystems is largely unexplored. Here, we pair grazing experiments with a molecular survey to quantify protistan grazing and to characterize the composition of vent-associated protists in …

Late Embryogenesis Abundant Proteins And Mitochondrial Membranes From An Animal Extremophile: Insights Into Severe Water Stress, John Marcus Anderson

LSU Doctoral Dissertations

This dissertation focuses on two major topics germane to mechanisms by which animals tolerate extreme water stress. First, the impact of transgenic expression of late embryogenesis abundant proteins (LEA) on water stress tolerance of the fruit fly Drosophila melanogaster was investigated. The overall aim was to extend current understanding of the protective properties of LEA proteins documented with isolated cells to a desiccation-sensitive organism during exposure to drying and hyperosmotic stress. Four lines of D. melanogaster were created that expressed transgenes encoding selected LEA proteins originally identified in embryos of the extremophile Artemia franciscana. After 80% tissue water loss, …

Long Term Effects Of Cash Transfer Programs In Colombia, Orazio Attanasio, Lina Cardona-Sosa, Carlos Medina, Costas Meghir, Christian Posso

Cowles Foundation Discussion Papers

Conditional Cash transfer (CCT) programs have been shown to have positive effects on a variety of outcomes including education, consumption and health visits, amongst others. We estimate the long-run impacts of the urban version of Familias en Acción, the Colombian CCT program on crime, teenage pregnancy, high school dropout and college enrollment using a Regression Discontinuity design on administrative data. ITT estimates show a reduction on arrest rates of 2.7pp for men and a reduction on teenage pregnancy of 2.3pp for women. High school dropout rates were reduced by 5.8pp and college enrollment was increased by 1.7pp for men.

Inanimate Life, George Briggs

Milne Open Textbooks

Inanimate Life is an open textbook covering a very traditional biological topic, botany, in a non-traditional way. Rather than a phylogenetic approach, going group by group, the book considers what defines organisms and examines four general areas of their biology: structure (their composition and how it comes to be), reproduction (including sex), energy and material needs, and their interactions with conditions and with other organisms. Although much of the text is devoted to vascular plants, the book comparatively considers ‘EBA = everything but animals’ (hence the title): plants, photosynthetic organisms that are not plants (‘algae’, as well as some bacteria …

Factors Influencing Rural Women’S Physical Activity Behaviors: A Social Ecological Perspective, Karen Lynn Webb

Nursing ETDs

ABSTRACT

Chronic disease and poor mental health are disproportionally impacting adults living in rural America. Regular physical activity has been shown to promote overall well-being and prevent many chronic diseases. Yet, research shows that many rural adults do not engage in enough physical activity to meet the recommended levels put forth by the federal government. The purpose of this descriptive qualitative study was to explore and describe the experiences of physical activity as perceived by rural women in their own words. Data were collected through semi-structured individual interviews of 20 women aged 25 to 34 living in McDowell County, West …

Early Detection Of Wildlife Morbidity And Mortality Through An Event-Based Surveillance System, Terra R. Kelly, Pranav S. Pandit, Nicole Carion, Devin F. Dombrowski, Krysta H. Rogers, Stella C. Mcmillin, Deana L. Clifford, Anthony Riberi, Michael H. Ziccardi, Erica L. Donnelly-Greenan, Christine K. Johnson

Faculty Research, Scholarly, and Creative Activity

The ability to rapidly detect and respond to wildlife morbidity and mortality events is critical for reducing threats to wildlife populations. Surveillance systems that use pre-diagnostic clinical data can contribute to the early detection of wildlife morbidities caused by a multitude of threats, including disease and anthropogenic disturbances. Here, we demonstrate proof of concept for use of a wildlife disease surveillance system, the 'Wildlife Morbidity and Mortality Event Alert System', that integrates pre-diagnostic clinical data in near real-time from a network of wildlife rehabilitation organizations, for early and enhanced detection of unusual wildlife morbidity and mortality events. The system classifies …

Eating is such a fundamental and enjoyable part of being human. However, for those dealing with age-related conditions such as Alzheimer's or Parkinson's disease the simple task of feeding oneself is far from straightforward. Struggling at mealtime not only endangers ones' health, but just as importantly, it comes with a sense of helplessness and embarrassment that causes additional emotional suffering and puts stress on relationships.
