Feeding is critical for survival, and disruption in the mechanisms that govern food intake underlies disorders such as obesity and anorexia nervosa. It is important to understand both food intake and food motivation to reveal mechanisms underlying feeding disorders. Operant behavioral testing can be used to measure the motivational component to feeding, but most food intake monitoring systems do not measure operant behavior. Here, we present a new solution for monitoring both food intake and motivation in rodent home-cages: the Feeding Experimentation Device version 3 (FED3). FED3 measures food intake and operant behavior in rodent home-cages, enabling longitudinal studies of …

"I Understand, Honey": Perceived Spousal Empathy's Moderating Influence On The Links Between Depression And Marital Satisfaction And Marital Satisfaction And Physical Health, F. Javier Celestino

Theses and Dissertations

An adapted version of the Vulnerability-Stress-Adaptation model was used as a theoretical guide for this study, which proposes that adaptive processes exist and can moderate relationships between enduring vulnerabilities and different outcomes. Relationships of interest include the negative link between depression and marital satisfaction and the positive link between marital satisfaction and physical health. An adaptive process of interest is empathy, due to its well-researched positive impact on mental, relational, and physical health. This study examined whether perceived spousal empathy (i.e., the empathy perceived by one spouse coming from their spouse) had any moderating effects on the previously mentioned links. …

The Effects Of U.S. Fiscal Policy On Income Inequality ( 1913 – 2013 ), J.D. Lewis

Theses and Dissertations

Income inequality in the United States has reached a level not seen since the Great Depression. Some academics and lawmakers suggest that growing inequality is due to changes in fiscal policy, arguing that cuts in taxes and government spending have reduced the inequality-mitigating effect of fiscal redistribution. While older research provides some support for this argument, newer research suggests otherwise. This disagreement in the literature led me to ask, How has fiscal policy affected income inequality in the United States during the last century? This study seeks to answer this question using data from Piketty et al. (2018), which includes …

Returns To International Migration: Evidence From A Bangladesh-Malaysia Visa Lottery, Ahmed Mushfiq Mobarak, Iffath A. Sharif, Maheshwor Shrestha

Discussion Papers

We follow 3,512 (of 1.4 million) applicants to a government lottery that randomly allocated visas to Bangladeshis for low-skilled, temporary labor contracts in Malaysia. Most lottery winners migrate, and their remittance substantially raises their family’s standard of living in Bangladesh. The migrant’s absence pauses demographic changes (marriage, childbirth, household formation), and shifts decision-making power towards females. Migration removes enterprising individuals, lowering household entrepreneurship, but does not crowd out other family members’ labor supply. One group of applicants were offered deferred migration that never materialized. Improved migration prospects induce pre-migration investments in skills that generate no returns in the domestic market.

Experience, But Not Age, Is Associated With Volumetric Mushroom Body Expansion In Solitary Alkali Bees, Mallory A. Hagadorn, Makenna M. Johnson, Adam R. Smith, Marc A. Seid, Karen M. Kapheim

Biology Student Research

In social insects, changes in behavior are often accompanied by structural changes in the brain. This neuroplasticity may come with experience (experience-dependent) or age (experience-expectant). Yet, the evolutionary relationship between neuroplasticity and sociality is unclear, because we know little about neuroplasticity in the solitary relatives of social species. We used confocal microscopy to measure brain changes in response to age and experience in a solitary halictid bee (Nomia melanderi). First, we compared the volume of individual brain regions among newly emerged females, laboratory females deprived of reproductive and foraging experience, and free-flying, nesting females. Experience, but not age, …

Faculty Publications

Pecan shells are a rich source of various bioactive compounds with potential antioxidant and antimicrobial properties. This study investigated the effect of pecan variety and method extraction on the antioxidant property of shell extracts. Twenty different varieties of pecan shells were subjected to either aqueous or ethanolic extraction and were examined for total phenolics and antiradical activity. The phenolic content and antiradical activity of shell extracts were significantly (p < 0.05) varied with different pecan cultivars. The total phenolic content of ethanol extracts ranged from 304.2 (Caddo) to 153.54 (Cherokee) mg GAE/g of dry extract and was significantly greater (p < 0.05) than those obtained by aqueous extraction. The antiradical activity of ethanol extracts ranged from 840.6 (Maramec) to 526.74 (Caper Fear) mg TEg-1, while aqueous extracts ranged from 934.9 (Curtis) to 468.3 (Elliot) mg TEg-1. Chemical profiling of the crude and acid hydrolyzed extracts was performed by reverse phase high performance liquid chromatography and flow injection electrospray ionization mass spectrometry. Lignin degradation products such as lignols, dilignols, trilignols, and oligolignols were found to be the major components of tested extracts. Phenolic content and antiradical activity of pecan shell extracts are significantly varied with cultivars and methods of extraction.
