Hardly Habitual: Chimpanzees And Gorillas Show Flexibility In Their Motor Responses When Presented With A Causally-Clear Task, Sarah L. Jacobson, Lydia M. Hopper

Publications and Research

In contrast to reports of wild primates, studies of captive primates' flexibility often reveal conservatism: individuals are unable to switch to new and more efficient strategies when task demands change. We propose that such conservatism might be a result of task design and hypothesize that conservatism might be linked to primates' lack of causal understanding in relation to experimental apparatuses. We investigated if chimpanzees (Pan troglodytes) and western lowland gorillas (Gorilla gorilla gorilla) would show greater flexibility when presented with a causally-clear task. We presented six chimpanzees and seven gorillas with a clear tube from which …

Large Pelvic Tubercle In Orangutans Relates To The Adductor Longus Muscle, Brian M. Shearer, Magdalena Muchlinski, Ashley S. Hammond

Publications and Research

Orangutan pelves commonly exhibit a large, projecting tubercle in the iliopubic region, historically assumed to homologous to the pubic tubercle in humans. However, it is not clear whether this tubercle is a unique feature of Pongo, or if it is anatomically homologous with the human pubic tubercle when considered as a soft tissue attachment point. To clarify this issue, we dissected orangutan and other ape cadaveric specimens to evaluate the pelvic brim soft tissues and how they may relate to the tubercle (when present). We additionally conducted a broad osteological survey of pelvic brim morphology across 28 primate genera …

Interest Rate And Commodity Price Impacts On Farm-Level Financials, Ann Denk

Agribusiness and Applied Economics

The agriculture industry has been around for hundreds of years. Although farmers and ranchers work every day to put food on the tables of billions of people from all around the world, most agricultural producers require assistance to finance their operations and continue production. This research is motivated by recent changes in interest rates and the downturn in agricultural commodity prices. This study examines how farm-level financial statements are impacted by changes in interest rates and agricultural commodity market prices. A Monte Carlo simulation is used to model several stochastic variables and derive key financial calculations. This study shows how …

Modern Theoretical Approaches To Medieval Translation, Michelle R. Warren

Dartmouth Scholarship

This chapter explores some of the ways in which modern literary theory opens insights into medieval European translations. Rather than drawing a distinction between theoretical approaches that apply to medieval studies and those that do not, I will explore a few examples that might in turn inspire readers to their own insights. It is my hope that over time readers of this Companion to Medieval Translation will posit many more modern theoretical approaches to medieval translation than can be suggested here. We might even imagine that some of the particularities of medieval European theories of translation could themselves be codified …

How Much Do Emotional, Behavioral, And Cognitive Factors Actually Impact College Student Attitudes Towards English Language Learning? A Quantitative And Qualitative Study, Xin Zuo, Regina D. Weaver, Julia Macrae, Limin Wang

Intensive English Language Program Faculty Publications and Presentations

Researchers have proposed many multidimensional frameworks to identify significant and potential factors, e.g., educational background, positive feelings and career aspirations, that impact English learning attitude in second language acquisition. Yet, there is still very little research to graphically describe the interactions between these factors and how these factors directly or indirectly impact learning attitude. To this end, a questionnaire survey was conducted in Changchun University of Technology. Statistical measures and Bayesian network analysis were introduced to quantitatively and qualitatively analyze the collected data. Furthermore, the significant attitudinal differences between students majoring in the Liberal Arts or Sciences were investigated for …

Maternal Nutrition, One-Carbon Metabolites, And Programming Of Fetal Development During Early Gestation, Matthew Scott Pennell Crouse

Animal Sciences

Crossbred Angus heifers (n = 14) were bred via AI, assigned to nutritional treatment (CON = 100% of requirements for 0.45 kg/d gain and RES = 60% of CON) and ovariohysterectomized on d 50 of gestation. Fetal liver, muscle from the hind limb, and cerebrum were analyzed by RNA-sequencing, and a total of 548, 317, and 151 genes, respectively (P < 0.01) were differentially expressed. Functional categories affected by nutritional treatment included: 1) Liver: metabolic pathways and nucleosome core, 2) Muscle: skeletal muscle and embryogenesis, and 3) Cerebrum: hippocampus and neurogenesis. Bovine embryonic fibroblast cells were cultured in Eagle’s Minimum Essential Medium with 1 g/L glucose (LOW) or 4.5 g/L glucose (HIGH). Control medium contained basal concentrations of one-carbon metabolites (Choline, folate, vitamin B12, and methionine). One-carbon metabolites (OCM: methionine, choline, folate, vitamin B12) were supplemented to the media at 2.5, 5, and 10 times (2.5X, 5X, and 10X, respectively) the control media, except for methionine, which was limited to 2X. One-carbon metabolites increased (P < 0.01) basal respiration and Reserve Capacity in HIGH 2.5X and 10X compared with all other treatments. ATP-linked respiration was greater (P < 0.01) in HIGH OCM supplemented cells compared to Control and was greater in LOW 2.5X compared with LOW Control, 5X, and 10X cells. Total growth rate was greater (P < 0.01) for HIGH 2.5X and 10X compared with LOW Control, 2.5X, and 10X. At 24, 36, 48, and 72 h, cell proliferation in HIGH 10X was always greater (P ≤ 0.03) than Low 10X. Therefore, these data are interpreted to imply that a moderate maternal nutrient restriction during the first 50 d of gestation in beef heifers alters the transcript abundance of genes impacting tissue accretion, function, and metabolism suggesting potential alterations to fetal physiology which should be further investigated. Lastly, supplementation of OCM may improve fetal growth and program increased metabolic efficiency in the offspring, and thus should be a focus of future research into the effects of maternal nutrition on postnatal physiology.

Perceptions Of Modern Meat-Animal Production From Consumers Two To Three Generations Removed From The Farm, Demetris Deon Reed

Animal Sciences

A consumer is defined as a person who purchases goods and services for personal use or a person or thing that eats or uses something (Merriam-Webster, 2019). Consumers either want or need to eat meat, whether it is for self-gratification or nutritive purposes. The modern consumer definition of “meat” has changed from the original hunter stalking prey to now contemporary livestock production practices that confine and feed sophisticated diets in an effort to achieve outstanding muscle-food quality. Those who produce and supply consumers with food and fiber must achieve a higher level of education in keeping with technological advances. Further, …

The Effects Of Red Meat Or Sugar Supplementation During Gestation And Lactation On Maternal Reproduction, Maternal And Offspring Blood Parameters, And Offspring Body Composition, Alexis Michelle Siomka

Animal Sciences

Using swine as a model for humans, this study was conducted to examine whether maternal consumption of added protein (red meat) or free sugar (glucose) throughout gestation and lactation was associated with maternal reproduction, maternal and offspring blood parameters, and offspring mature body composition. Maternal breed of sows of at least one year of age at breeding were utilized. At D-40 of gestation, sows were randomly assigned to one of four dietary supplementation treatments 1) Control (CON): corn-soy gestation diet; 2) Beef (GB): 4 oz cooked beef patty; 3) Sugar (SUG): sugar on a caloric equivalent to the beef patty; …

A Systematic Review Of What Barriers And Facilitators Prevent And Enable Physical Healthcare Services Access For Autistic Adults, David Mason, Barry Ingham, Anna Urbanowicz, Cos Michael, Heather Birtles, Marc Woodbury‑Smith, Toni Brown, Ian James, Clare Scarlett, Christina Nicolaidis, Jeremy R. Parr

School of Social Work Faculty Publications and Presentations

Autistic people are more likely to: be diagnosed with a range of physical health conditions (i.e. cardio-vascular disease); experience premature mortality (for most disease categories); and experience barriers to effectively accessing healthcare. This systematic review sought to identify studies that report on barriers and facilitators to physical healthcare access for autistic people. A total of 3111 records were screened and six studies were included: two quantitative, two qualitative, and two mixed-methodology studies. Patient-provider communication, sensory sensitivities, and executive functioning/planning issues emerged as important barriers to healthcare. Recommendations for clinicians and those planning services are discussed.

Improved Drought Resilience Through Continuous Water Service Monitoring And Specialized Institutions—A Longitudinal Analysis Of Water Service Delivery Across Motorized Boreholes In Northern Kenya, Nick Turman-Bryant, Corey L. Nagel, Lauren Stover, Christian Muragijimana, Evan A. Thomas

Complex Systems Faculty Publications and Presentations

Increasing frequency and severity of drought is driving increased use of groundwater resources in arid regions of Northern Kenya, where approximately 2.5 million people depend on groundwater for personal use, livestock, and limited irrigation. As part of a broader effort to provide more sustainable water, sanitation, and hygiene services in the region, we have collected data related to site functionality and use for approximately 120 motorized boreholes across five counties. Using a multilevel model to account for geospatial and temporal clustering, we found that borehole sites, which counties had identified as strategic assets during drought, ran on average about 1.31 …

A Systems Thinking Approach For Eliciting Mental Models From Visual Boundary Objects In Hydropolitical Contexts: A Case Study From The Pilcomayo River Basin, Riveraine S. Walters, Erin S. Kenzie, Alexander E. Metzger, William Jesse Baltutis, Kakali B. Chakrabarti, Shana Lee Hirsch, Bethany Laursen

Complex Systems Faculty Publications and Presentations

Transboundary collaborations related to international freshwater are critical for ensuring equitable, efficient, and sustainable shared access to our planet’s most fundamental resources. Visual artifacts, such as knowledge maps, functioning as boundary objects, are used in hydropolitical contexts to convey understandings and facilitate discussion across scales about challenges and opportunities from multiple perspectives. Such focal points for discussion are valuable in creating shared, socially negotiated priorities and integrating diverse and often disparate cultural perspectives that naturally exist in the context of international transboundary water resources. Visual boundary objects can also represent the collective mental models of the actor countries and transboundary …

Investigating Metrical Context Effects On Anticipatory Coarticulation In Connected Speech Development, Jillian Adkins, Christina Gildersleeve-Neumann, Melissa A. Redford

Speech and Hearing Sciences Faculty Publications and Presentations

If rhythm acquisition is influenced by the development of articulatory timing, then metrical structure might be expected to condition this timing. This study tested this hypothesis by investigating anticipatory effects of an upcoming noun on the production of a preceding determiner, under the assumption that anticipatory coarticulation indexes chunking. Simple S-V-O sentences were elicited from 5-year-olds, 8-year-olds, and adults. The V was either monosyllabic packed or disyllabic patted. The O was a determiner phrase where nouns varied either in onset place-of-articulation (POA; tack vs. cat) or in their rhymes (tack vs. toot). Acoustic analyses of determiner schwa F1 and F2 …
