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 …

Huanglongbing (HLB), also known as citrus greening disease, poses a severe threat to the global citrus industry. This disease is caused by three species of bacteria, ‘Candidatus Liberibacter asiaticus’, ‘C. L. africanus’, and ‘C. L. ameri-canus’. The primary pathogen vectors are the Asian citrus psyllid (Diaphorina citri Kuwayama, Hemiptera: Psyllidae) and the African citrus psyllid (Trioza erytreae Del Guercio, Hemiptera: Triozidae). The disease is incurable, and its management relies on reducing vector densities and the adverse effects of bacterial infections on host trees. Managing psyllid vec-tors, especially D. citri, has proven exceptionally challenging due to its rapid spread and subsequent …

The Relationship Between Brain Perfusion And Structure In Youth With Obesity, With And Without Type 2 Diabetes: A Pilot Study., Ryan P. Brady, Amy S. Shah, Mekibib Altaye, Jacob M. Redel, Dean W. Beebe, Mark W. Difrancesco

Manuscripts, Articles, Book Chapters and Other Papers

Neurocognitive decline, dementia, and stroke are associated with obesity and type 2 diabetes (T2D) in adults. Youth-onset T2D and obesity are occurring more frequently, increasing the risk of earlier onset brain-related morbidity. Emerging evidence has demonstrated global and regional changes in gray matter volume (GMV) and cerebral blood flow (CBF) in youth with T2D and obesity as well. Understanding brain pathophysiology in youth-onset T2D and obesity requires more complex and multi-modal investigation of the brain, such as integration of brain structure and perfusion. Twenty youth with T2D and nineteen age, race, sex, and body mass index (BMI) similar youth with …

How Do People Change Their Beliefs About Climate Change? A Qualitative Study On Opinion Shift In The U.S. Midwest, Emily A. Hurley, Michael S. Molloy

Manuscripts, Articles, Book Chapters and Other Papers

Beliefs and attitudes about climate change are the building blocks from which humans create and support mitigation and adaptation strategies. In the United States, 72% of the public now believes that the earth is warming and 58% believe humans are the cause. Although these figures represent some increase since 2010, they also represent a significant remaining gap in acceptance of climate change realties. While a wealth of research has identified isolated factors that influence opinions on climate change, less attention has been given to understanding the process that changes people’s opinions. Our study uniquely applies qualitative methods to examine the …

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: To date, the focus of investigation in pediatric pulmonary embolism (PE) has been on PE recurrence and anticoagulant-related bleeding. While highly relevant, these outcomes do not fully capture functional limitations and the psychological impact that comprises post-PE syndrome.

OBJECTIVES: The primary objective of the Functional Characterization of Venous Thromboembolic Disease (FUVID) study was to investigate mechanisms of post-PE syndrome in children.

METHODS: The ongoing FUVID study will prospectively enroll and systematically follow, over 12 months and with standardized pulmonary, cardiac, and muscle testing, a multicenter prospective cohort of 80 pediatric patients with first-episode PE without comorbidities. FUVID has 2 …

Approval Of Parent-Child Aggression As A Mediator Of Intergenerational Child Abuse Risk: An Evaluation Of Racial Differences, Casie H. Morgan, Christina M. Rodriguez, Doris F. Pu, Zoe O. Elkins

Psychology Faculty Publications

Purpose

Personal history of parent-child aggression (PCA) can predict future parenting behavior, but some effects may differ between racial groups. Black parents in the U.S. are more likely to encounter discrimination and personally experience and approve of PCA, which may account for previously reported group differences. This study examined whether personal PCA history predicted later parental child abuse risk mediated by PCA approval across the transition to parenthood, and whether effects differed by race.

Methods

Expectant parents (non-Hispanic White sample: 95 mothers with 86 fathers; Black sample: 94 mothers with 85 fathers) participated in a prospective longitudinal study, assessed prenatally …

Exploring Differences In Cannabis Use And Harm Perceptions Among Sexual Minority And Heterosexual Females: A Brief Report, Sarah J. Ehlke, Samantha A. Fitzer, Kendra Rigney

Psychology Faculty Publications

Objective: Sexual minority women (SMW) have higher rates of cannabis use compared to heterosexual women, which may be partially attributed to lower harm perceptions. However, no study has examined if the association between harm perceptions and cannabis use is stronger for SMW than heterosexual women. This study examined if sexual identity (SMW vs. heterosexual woman) moderated the association between harm perceptions and past 30-day cannabis use among a sample of female young adults (18-25 years old). Method: Participants were 949 (29.8% SMW; Mean age = 24.33; 92.1% non-Hispanic White) females (99.3% cisgender) recruited from Amazon Mechanical Turk who reported weekly …

Method

In total, 56 post-9/11 veterans were recruited with 28 randomized to the MMMI condition and 28 to the Education and Support (ES) condition. Most participants identified as being White (71.4%), male (66.1%), and had a reported mean age of 41.50 years (Median = 39.50, SD = 9.26).

Results

Among the 56 participants, 82.1% attended at least one treatment session and 44.6% completed all seven sessions. There …

Anhedonia Links Sleep Problems And Suicidal Thoughts: An Intensive Longitudinal Study In High-Risk Adolescents, Kinjal K. Patel, Jaclyn C. Kearns, Dan Foti, Wilfred R. Pigeon, Evan M. Kleiman, Catherine R. Glenn

Psychology Faculty Publications

Growing research indicates that sleep problems are a robust independent risk factor for suicidal thoughts and behaviors among youth. However, relatively little is known about how this risk is conferred. This study used an intensive longitudinal design to investigate anhedonia as a mechanism linking sleep problems and next-day suicidal thoughts in a clinically high-risk sample of adolescents. Adolescents (N = 48; M_age=14.96; 77.1% white, 64.6% female) completed an ecological momentary assessment (EMA) study design for 28 days following discharge from acute psychiatric care for suicide risk. Daily sleep diaries were used to assess prior night total sleep …

Check Your Data Before You Wreck Your Model: The Impact Of Careless Responding On Substance Use Data Quality, Abby L. Braitman, Anna M. Petrey, Jennifer L. Shipley, Rachel Ayala Guzman, Emily Renzoni, Alison Looby, Adrian J. Bravo

Psychology Faculty Publications

Background: The accuracy of survey responses is a concern in research data quality, especially in college student samples. However, examination of the impact of removing participants from analyses who respond inaccurately or carelessly is warranted given the potential for loss of information or sample diversity. This study aimed to understand if careless responding varies across a number of demographic indices, substance use behaviors, and the timing of survey completion.

Method: College students (N = 5809; 70.7% female; 75.7% White, non-Hispanic) enrolled in psychology classes from six universities completed an online survey assessing a variety of demographic and substance use-related information, …

Psychometric Evaluation Of A Novel Measure Of Trauma-Related Cannabis Use To Cope, Sage E. Hawn, Terrell A. Hicks, Christopher Latourrette, Anita Thomas, Daniela Chaname, Sarah Ehlke, Abigail Powers Lott

Psychology Faculty Publications

Background: Posttraumatic stress disorder (PTSD) and cannabis use disorder (CUD) are commonly comorbid and are associated with many negative public health outcomes. One plausible explanation for this comorbidity comes from a self-medication framework, which suggests people use cannabis to cope with PTSD symptoms. Despite theoretical and empirical evidence for PTSD-related cannabis use to cope, no measure of this construct exists.

Objective: We sought to address this gap by developing and validating a novel measure of PTSD-specific cannabis self-medication, which we have termed the Trauma-Related Cannabis Use to Cope (TRCU) questionnaire.

Method: The psychometric properties of the TRCU and how it …

Influence Of Time Pressure And Flood Information Type On Flood Alert Effectiveness In Driving, Katherine R. Garcia, Scott Mishler, Jing Chen

Psychology Faculty Publications

Flood alerts are a means of risk communication that alerts the public to potential floods. The purpose of this research was to investigate factors that affected drivers' understanding and actions given a flood presented through a mobile navigation application. Two experiments were conducted to examine the effects of time pressure and type of flood information on drivers' planned actions when faced with potential flooding. Participants were asked about their planned actions given one type of flood information in a driving scenario either with or without time pressure. Our results indicated significant differences in participants' behaviors across the different flood information …

Brief Videos During Informed Consent May Be Helpful For Participants' Understanding Of Study Information, Abby L. Braitman, Rachel Ayala Guzman, Kristin E. Heron

Psychology Faculty Publications

Although an informed consent process is required for all research, it is not clear how well study participants read informed consent forms and understand their content. A systematic review of medical clinical trials revealed participants had only a 50% rate of understanding for concepts of the consent process, including voluntary participation, blinding, and freedom to withdraw, with lower rates for randomization, risks, and safety issues (Pietrzykowski & Smilowska, 2021). This issue may be more pronounced for online research, with a recent study indicating half of participants report not reading informed consent forms at all (Perrault & Keating, 2017). Although increasing …

The Impact Of Peer Observational Learning On Honesty Following A Transgression, Hannah M. Sliman, George H. Noell

Psychology Faculty Publications

Parents and teachers worry about how lying affects children's development and socialization, as research links persistent lying to delinquency, aggression, and conduct issues. To investigate this, we examined two groups: Honest and Praise versus a Control Group, exploring how exposure influenced children's honesty and confession after transgressions. The study aimed to see if observing peers receive praise for honesty could promote truthfulness. Gender's impact on reporting honesty was assessed. Results showed no significant difference in honesty between the HP and CG groups; children confessed at similar rates in both conditions. Gender did not affect honest reporting. These findings differ from …

Sounds Of Silence: Using The Stereotype Content Model To Understand Perceptions Of Introverts And Extraverts At Work, Mallory A. Mccord

Psychology Faculty Publications

This paper drew on the stereotype content model (SCM) to clarify cultural stereotypes about introverted and extraverted people at work to increase our understanding of the stereotype-driven process that may lead to negative responses to introversion and subsequent detriment to employee health and well-being. The hypothesis that introverted workers would be rated as lower in warmth and competence than extraverted workers was examined across three studies. Study 1 used qualitative content analyses to assess open responses that freely described introverted and extraverted colleagues. Study 2 tested the hypothesis quantitatively using established measures of warmth and competence. Finally, Study 3 tested …

Family Stress Processes Underlying Covid-19-Related Economic Insecurity For Mothers And Fathers And Children's Internalizing Behavior Problems, Joyce Y. Lee, Shawna J. Lee, Sehun Oh, Amy Xu, Angelise Radney, Christina M. Rodriguez

Psychology Faculty Publications

COVID‐19 and its economic fallout have resulted in unprecedented financial insecurity and material hardship for many American families, with a disproportionately negative impact on children and families from socioeconomically disadvantaged contexts. The current study applied the family stress model to examine the family processes underlying pandemic‐related economic insecurity and children's internalizing behaviours. Online survey data from an economically diverse sample of mothers and fathers, who experienced at least one type of pandemic‐related economic insecurity in the United States (N = 259), were collected across two longitudinal time points in the early weeks of COVID‐19: (1) 14 April and (2) 30 …

Pregnant Adults' Interest In Physical And Mental Health Behavior Change Interventions Using Mobile Technology, Natalie M. Yarish, Cassidy M. Sandoval, Alicia Moulder, Meredith I. Turner, Danielle Symons Downs, Kristin E. Heron

Psychology Faculty Publications

Improving the health and well-being of pregnant adults is an important public health priority in the USA, and mobile health (mHealth) interventions may provide a scalable strategy to disseminate behavior change programs to pregnant adults. This study assessed pregnant people’s use of mobile technology, interest in making health behavior changes during and after pregnancy, and their willingness to use mHealth interventions. Participants were 133 pregnant adults (M_age = 27.86; 81% White) living across the USA recruited from social media to complete an online survey. Measures assessed mobile technology use and beliefs about improving mental/physical health in pregnancy and postpartum …

Graduate And Undergraduate Quantitative Education In Psychology In The United States: A Mixed Methods Approach, Abby L. Braitman, James M. Henson

Psychology Faculty Publications

Quantitative methodology is part of the core curriculum for training in psychology and is required of graduate students across all subdisciplines; as such, the depth and breadth of course content is a universal issue among psychology training programs. Required and supplemental quantitative content is constantly evolving with the development of new techniques or applications. Therefore, the purpose of this inquiry was fourfold; we aimed to (1) describe the current state of undergraduate quantitative education and establish a common set of current undergraduate curricular topics; (2) characterize graduate quantitative education in terms of required coursework, optional coursework, and omitted topics; (3) …

Vagally Mediated Heart Rate Variability Modulates The Association Between The Perceived Workload And The Stroop Effect On Behavioral Performance, Xiao Yang, Michael Gazzanigo, Fang Fang, Spencer House

Psychology Faculty Publications

Vagally mediated heart rate variability (vmHRV) reflects top-down cognitive processes involved in emotion-cognition integration. Using cognitive control can be effortful and increase negative affect. However, this intrinsic affective component of cognitive control has not been well studied, and the role of vmHRV in the association between subjective experience in using cognitive control and behavioral performance remains unknown. The current study aimed to examine the relationship of vmHRV with cognitive control and perceived workload in a cognitive task. Eighty-one participants performed the Stroop interference task. Participants rated subjective workload using the NASA Task Load Index (NASA-TLX) scale for congruent and incongruent …

Willingness To Use Long-Acting Injectable Pre-Exposure Prophylaxis (Lai-Prep) Among Black Cisgender Women In The Southern United States, Sylvia Shangani, Jaquetta M. Reeves, Kristin Heron, Jessica M. Sales, Kenneth K. Mugwanya

Psychology Faculty Publications

Background

Long-acting injectable pre-exposure prophylaxis (LAI-PrEP) for HIV prevention may improve adherence for those with concerns with daily pills. Limited data exist on LAI-PrEP acceptability among Black women in the U.S., a population vulnerable to HIV. We assessed willingness to use LAI-PrEP among Black women eligible for PrEP in the Southern U.S.

Methods

We conducted a cross-sectional online survey of HIV-negative Black women from March to June 2022 in the U.S. South. Participants provided information on sociodemographic characteristics, HIV knowledge, PrEP awareness, and use, stigma, risk perception, medical mistrust, and healthcare access. Multivariate logistic regression models determined factors associated with …

Identifying Salient Social, Environmental, And Situational Contexts Of College Drinking: Impacts Across Drinking Outcomes, Abby L. Braitman, Jennifer L. Shipley, Megan Strowger, Emily S. Renzoni

Psychology Faculty Publications

Background and Objectives: Drinking context, such as where, why, and under what social conditions drinking occurs, is consistently associated with daily variability in alcohol use. However, ecological momentary assessment (EMA) requires very brief measurement, not allowing for as many contextual assessments as researchers may like. The current investigation examined common contextual predictors and their associations with different alcohol outcomes.

Methods: A sample of N=528 college drinkers completed three surveys about their most recent drinking episode. This included contextual predictors (location, social context, who was present, alcohol offers, and drinking motives), as well as typical drinking outcomes (number of drinks, estimated …

Evaluation Of A 20-Item Version Of The Trauma-Related Drinking To Cope Questionnaire, Sage E. Hawn, Lauren Smith, Kaytlin Armitage, Selah Ball, Cathy Lau-Barraco, Abigail Powers, Ananda B. Amstadter

Psychology Faculty Publications

Objectives: This study sought to develop and psychometrically evaluate an expanded version of the Trauma-Related Drinking to Cope (TRD) scale, a four-item self-report tool, which was developed to address a crucial gap in self-medication research. Before the development of the TRD, no measures existed which assessed alcohol use for coping with symptoms of posttraumatic stress disorder (PTSD) specifically. Previous work showed that the TRD has strong psychometric properties and clinical utility in its ability to identify individuals with PTSD who may be at risk for developing comorbid alcohol use disorder (AUD). The aim of the present study was to develop …

Am I As Effective At Identifying Emotions As Artificial Intelligence? A Comparative Study Of Emotional Recognition, Traci R. Grove, Alexandra T. Lucas, Maryann Martin, Cathleen M. Deckers, Lulu Sherif Mahmood, Nicole Danaher-Garcia, Mark W. Scerbo, Suzan Kardong-Edgren, Janice C. Palaganas

Psychology Faculty Publications

Background

Learning conversations, or dialogues aimed at deepening understanding and reflection, are deeply influenced by emotions. Effective communication is influenced by emotional intelligence - the ability to recognize, understand, and manage both one’s own and others’ emotions. While advances in artificial intelligence (AI) offer new tools for emotion recognition, these technologies still struggle with accurately interpreting subtle and culturally diverse emotional expressions, sparking debate about their reliability and effectiveness. This article provides a comparative analysis of human versus AI recognition of emotions during an end-of-course reflective learning conversation.

Methods

Emotions during a structured post-conference debriefing were analyzed and coded by …

Parent Ptsd, Social Support And Differential Associations With Facets Of Anxiety Sensitivity, Kristen Bermingham, Christopher Latourrette, Karen G. Chartier, Spit For Science Working Group, Ananda B. Amstadter, Kaitlin Bountress

Psychology Faculty Publications

Background: Anxiety Sensitivity (AS), the belief that anxiety experiences have negative implications, is a prospective predictor of posttraumatic stress disorder (PTSD) and has been linked to changes in PTSD in experimental studies. AS is comprised of three sub-components: cognitive, physical, and social concerns. PTSD is moderately heritable and parental PTSD may increase risk for these AS facets both directly and through environmental influences like reduced social support.

Objective: The present study will examine whether Parent PTSD is associated with reduced social support and in turn facets of AS.

Method: Participants were recruited from an ongoing longitudinal study of college student …

Understanding The "Paradox" In Black-White Alcohol Outcomes: Examining High-Effort Coping And Health Behaviors With A Focus On Black Populations And College Students, Rachel Ayala Guzman, Abby L. Braitman

Psychology Faculty Publications

Despite experiencing more physical health disadvantages and psychosocial stressors, Black Americans consistently report better mental health outcomes compared to White Americans—a phenomenon commonly referred to as the Black-White health paradox. Alcohol research has identified another racial paradox suggesting Black Americans are at greater risk for alcohol-related problems despite drinking less than White Americans, which is known as the Black-White alcohol paradox. While both paradoxes are well-documented, few studies have examined their potential overlap or how insights from one might inform understanding of the other. Although the alcohol paradox is usually examined among older adults, it may be important to consider …

Other Publications

Health data hosted by the U.S. federal government have been disappearing. According to our analysis, between January 21 and February 11, 2025, the Centers for Disease Control and Prevention (CDC) removed 203 datasets (13% of its online datasets, a reduction from 1519 to 1316). The situation is dynamic; various datasets have been removed, restored, manipulated, or not posted as planned.

How Artificial Intelligence Will Shape Securities Regulation, Gabriel Rauterberg

Other Publications

How will the increasing prevalence and sophistication of artificial intelligence (AI) change the doctrine and practice of securities law? My main thesis is that it will push securities regulation toward a more systems-oriented approach. This approach will replace securities law's emphasis, in areas like manipulation, on forms of enforcement targeted at specific individuals and accompanied by punitive sanctions with a greater focus on ex ante rules designed to shape an ecology of actors and information.

Against Judicial Generalists, Matthew L.R. Fletcher

Other Publications

There is something irritatingly wrong with Indian law practice at the Supreme Court.

Oral argument at the Supreme Court is a bitterly unpleasant affair for Indigenous people and tribal advocates for a lengthy variety of reasons. It is canonical that tribal advocates must attempt to avoid Supreme Court review; the strategic thinking is that the Court is the last place an Indian tribe would ever want to be. No Indigenous person has argued a case before the Supreme Court since 2001, approaching a quarter century. Only a tiny handful of Indigenous people have ever clerked for a Supreme Court justice. …
