Patients were randomly assigned into two equal groups: Group I received digital complete overdentures with digitally created …

The Direct And Indirect Effects Of Mobile Phone Ownership On Maize Yields In Tanzania, Cool Dady Mangole, Kelvin Mulungu, Christian Kamala Kaghoma, Menale Kassie

All Peer-Reviewed Publications

The study uses the Living Standards Measurement Study-Integrated Surveys on Agriculture to evaluate mobile phone ownership's direct and indirect effect on yields in Tanzania. The results indicate that transitioning from not owning to owning a mobile phone improves maize yields by about 16%. Mobile phones indirectly affect maize yield by facilitating farmers' access to extension services - regardless of the type of provider - but only account for about 2% of the total effects. Considering both direct and indirect effects, this study suggests that extension services partially moderate this causal relationship. Further, the impact of mobile phones is stronger among …

Advances in next-generation sequencing have allowed the use of DNA obtained from unusual sources for wildlife studies. However, these samples have been used predominantly to sequence mitochondrial DNA for species identification while population genetics analyses have been rare. Since next-generation sequencing allows indiscriminate detection of all DNA fragments in a sample, technically it should be possible to sequence whole genomes of animals from environmental samples. Here we used a blood-feeding insect, tsetse fly, to target whole genome sequences of wild animals. Using pools of flies, we compared the ability to recover genomic data from hosts using the short-read sequencing (Illumina) …

All Peer-Reviewed Publications

This review examines the use of insect meal (IM) as a substitute for fishmeal (FM) in fish feeds within the past decade. While global interest in this alternative is growing, research on its effects on fish digestibility, blood parameters, and economic performance has been limited. Meta-analysis on the apparent digestibility coefficient revealed a negative effect summary on dry matter (0.92) and crude lipid (0.51), although the difference between the two groups was relatively minor. However, a positive effect summary was reported in the apparent digestibility of crude protein (0.12), suggesting a potential advantage in the utilization of protein by fish …

Aflatoxin Prevalence And Association With Maize Grain Physical And Nutritional Qualities In The Informal Markets In Meru County, Kenya, C. Cherotich, M. W. Okoth, Abong’ Go, S. W. Kariuki, E. R. Omuse

All Peer-Reviewed Publications

In Kenya, aflatoxin contamination in maize remains a persistent issue, with potential negative impacts on both public health and economic growth. Aflatoxins are toxic secondary metabolites produced by certain mold species, primarily Aspergillus flavus. The extent of Aspergillus fungal invasion in maize grains and the resulting increase in aflatoxin levels is heavily influenced by pre-and post-harvest practices. Before harvest, factors such as insect damage and exposure to warm, humid conditions increase the crop's susceptibility to Aspergillus infection and subsequent aflatoxin formation. Post-harvest, additional risks arise when kernels are damaged by pests like rats or when they are stored in unfavorable …

The United States Healthcare System: From Medicare To Post-Pandemic Health Policy, William M. Sage

Faculty Scholarship

My purpose in this essay is to comment on national health policy in the United States over the past sixty years.  My conclusions are less optimistic than what I had hoped when I began my teaching and research career in the 1990s to be able to say in 2025.  In particular, the successful expansion of publicly supported health coverage via the passage of the Affordable Care Act (“ACA” or “Obamacare”) in 2010 seems to have triggered -- though I hesitate to say that it caused – a backsliding from broader commitments to clinical performance, population health, and social solidarity that …

Border Decriminalization As A State Project: Lessons From Marijuana And Assisted Suicide Legalization Across The United States, Victor C. Romero

Faculty Scholarship

My prior work argued for the decriminalization of border crossings without proof of specific intent to violate another law (like drug trafficking), which is even less likely to happen now than it was when the piece was published, given the current presidential administration’s zealous deportation strategy and Congress’s seeming acquiescence. As such, I advocate for a second-best solution involving federal-state cooperative agreements wherein border states abutting both Mexico and Canada are given the option by the federal government to pass local legislation decriminalizing border crossings into their states as their communities desire. To the extent that the current presidential administration …

Effect Of Paxlovid On Neurodevelopmental Disorder Diagnosis Outcomes In Offspring Of Mothers Infected With Sars-Cov-2 During Pregnancy, Simone Rogers

CMC Senior Theses

The onset of the 2020 COVID-19 pandemic brought concern over the effects that this virus would have on pregnancy and fetal outcomes, specifically neurodevelopmental outcomes. Maternal immune activation (MIA), caused by infection during pregnancy, is known to result in neurodevelopmental disorder (NDD) diagnosis in offspring, typically autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD). This effect has already been observed in mothers who were infected with COVID-19 during pregnancy. However, in 2023, Paxlovid, the COVID-19 antiviral drug, became available to patients experiencing symptoms of the virus, including pregnant women. Consequently, this study seeks to determine whether the risk of …

Addressing Chronic Stress: Activating The Healing Responses, Lily Walther

CMC Senior Theses

This paper seeks to explore the negative effects of chronic stress on the body, emphasize the tissue, cellular, and genetic healing responses that exist to combat these effects, and illustrate the behavioral and physiological interventions that can activate these responses. The concepts of stress and chronic stress have been explained through a progression of models that have been updated over the decades. This includes early theories such as The General Adaptation Syndrome and the Homeostatic Model, as well as more recent depictions such as the Reactive Scope Model. The healing responses are explored on a variety of levels to illustrate …

A Spectroscopy Study Of The Brain: Exploring Sex Differences In Healthy Older Adults, Angela Gushue

CMC Senior Theses

Cognitive decline and aging-related disorders, such as Alzheimer’s, disproportionately affect patients based on sex, but the mechanisms underlying these skewed effects are unknown. This proton magnetic resonance spectroscopy (H-MRS) study seeks to understand if sex disparities in aging exist in neurometabolite concentrations of older adult brains. Sixty-seven participants, ranging from 60 to 85 years of age, underwent the Montreal Cognitive Assessment (MoCA) and H-MRS of the brain. Concentrations of myo-inositol, total creatine, total NAA, and total choline were calculated in the dorsal posterior cingulate cortex, left hippocampal cortex, left medial temporal gyrus, left primary sensorimotor cortex, and right dorsolateral prefrontal …

From Fields To Fast Foods: Food Culture, Identity, And Health In Puerto Rico Under The U.S. Empire, Ivanna Morales Mercado

CMC Senior Theses

Operation Bootstrap, launched in 1947, fundamentally altered Puerto Rico’s economy, just as much as its food culture. Prioritizing manufacturing over agriculture led to the collapse of the island’s farming sector, increasing reliance on food imports and leading to a rise in diet-related diseases such as obesity, type 2 diabetes, and cardiovascular issues. This thesis examines the legacies of Operation Bootstrap on Puerto Rico’s food system, health outcomes, and cultural identity by emphasizing the need to value intergenerational knowledge. The oral history research in this study highlights the importance of intergenerational knowledge in reclaiming sustainable agricultural practices and healthy, culturally significant …

Beyond Teaching A Man To Fish: Smallholder Cultivation, Certification, And Cooperation In Southeast Asian Aquaculture, Sasha Shunko

CMC Senior Theses

This thesis explores the barriers and opportunities facing smallholder aquaculture farmers in Southeast Asia, focusing on Thailand. It examines how certification systems, technical assistance, and policy interventions can effectively include smallholders in development and sustainability efforts. Based on field interviews with Thai shrimp farmers, analysis of certification schemes, and review of other agricultural intervention models, the research traces how market access, corporate concentration, and environmental change shape smallholder livelihoods.

The findings show that while certification is promoted as a tool for sustainability and market integration, in practice it often excludes the very farmers it seeks to empower. Redundant standards, limited …

Neural Correlates Of Attentional Biases In Dietary Choice: Role Of Childhood Socioeconomic Status, Justine Jamie N. Gotico

CMC Senior Theses

Childhood poverty has been shown to increase adult risk for obesity above and beyond its direct effects on adult socioeconomic status (SES). One proposed mechanism of these effects is by shifting behavioral patterns of dietary consumption and choice, for example by increasing rapid attention to high-calorie unhealthy foods. Yet, whether such neural mechanisms can explain observed differences in dietary behavior based on childhood SES remains an open question. Here we used event-related potentials (ERPs) to examine early attentional correlates of low childhood SES during a dietary choice task, based on research suggesting that early attentional biases toward high-calorie foods emerge …

The Politics Of (Mis)Perception: Understanding Americans’ Beliefs About Immigrant Welfare Usage, Ping Xu, Belinda Davis, Michael Henderson, James Garand

Political Science Faculty Publications

Background

Public concerns about immigrants' use of welfare programs have long influenced U.S. immigration and social policy. During the Trump administration, claims that immigrants exploit the American welfare system became central to the political agenda, amplifying perceptions that immigrants are economic burdens. These perceptions, whether grounded in reality or not, can shape public support for both immigration and the welfare state.

Aims

Few studies have systematically examined how closely Americans' perceptions of immigrants' welfare usage align with actual usage patterns, and how individual and contextual factors moderate this relationship. In this study we explore these connections.

Materials and Methods
