Partner Support And Connection Protect Couples During Pregnancy: A Daily Diary Investigation, Shaina A. Kumar, Rebecca L. Brock, David Dilillo

Department of Psychology: Faculty Publications

Objective: The objective of the current study was to examine associations between daily subjective stress and relationship satisfaction as a function of two protective factors—partner support and connection (i.e., intimacy, passion, and commitment)—among couples during pregnancy. Background: Stress brought into the intimate relationship by each partner is often associated with relational dissatisfaction and discord, referred to as stress spillover. Although much research has focused on risk for poor relational outcomes associated with partner stress, it is equally important to focus on resilience. Method: We examined this phenomenon among 154 couples navigating pregnancy. Couples attended an initial laboratory session and then …

Friends-Based Protective Strategies And Unwanted Sexual Experiences: A Daily Diary Examination Of First Year College Women, Jessica A. Blayney, Tiffany Jenzer, Anna E. Jaffe, Quinn Carroll, Jennifer P. Read

Department of Psychology: Faculty Publications

Risk for unwanted sexual experiences can emerge in social contexts—the same contexts that early college women navigate with their friends. Though friends naturally engage in prevention strategies, less is known about how capable guardianship influences risk. Using multilevel structural equation modeling, the present study examined guardianship at the person and situation levels. First-year college women (N = 132) completed eight weekends of daily surveys. We examined whether guardianship (e.g., more friends present, greater proportion of female friends, no intoxicated friends) would reduce unwanted sexual experience risk and if this relation was mediated by friends-based strategy use. An alternative model …

Psychological And Physical Intimate Partner Aggression Are Associated With Broad And Specific Internalizing Symptoms During Pregnancy, Gabriela R. Perez, Sara M. Stasik-O’Brien, Lauren M. Laifer, Rebecca L. Brock

Department of Psychology: Faculty Publications

Background: Intimate partner violence (IPV) has serious consequences, particularly during high-risk periods such as pregnancy, which poses a significant risk to maternal mental health. However, it is unclear whether IPV presents a broad risk for psychopathology or is specific to distinct diagnoses or symptom dimensions (e.g., panic, social anxiety). Further, the relative impact of physical versus psychological aggression remains unclear. Methods: One hundred and fifty-nine pregnant couples completed surveys assessing psychological and physical intimate partner aggression unfolding in the couple relationship, as well as a range of internalizing symptoms. Results: Psychological and physical aggression were each associated with broad negative …

Peer Coach Support In Internet-Based Cognitive Behavioral Therapy For College Students With Social Anxiety Disorder: Efficacy And Acceptability, Chandra L. Bautista, Allura L. Ralston, Rebecca L. Brock, Debra A. Hope

Department of Psychology: Faculty Publications

Social anxiety disorder is common among emerging adults and is associated with serious functional impairment. Cognitive-behavioral therapy (CBT) is an effective intervention for social anxiety. An online version may increase access but low completion rates limit utility. This study investigated a self-guided, internet based CBT (ICBT) with peer coach support. Participants were 35 undergraduate students randomized for immediate treatment (IT) or wait-list control (WL) in a randomized controlled trial design. IT participants completed a six-week ICBT program on their own and met briefly with a minimally trained undergraduate student as a “coach” between each lesson. IT participants had a greater …

Using Complex Behavior To Understand Brain Mechanisms In Health And Disease, Cassandra D. Gipson, Paul L. Soto, Erin S. Calipari, Donna M. Platt, John D. Salamone, Rick A. Bevins

Department of Psychology: Faculty Publications

At this point in the history of the science of behavior, a focus on neuroscience-based outcomes has become dominant in neuropsychiatric fields at the preclinical and clinical levels of analysis. The notion that behavior is caused by brain function, and that changing brain function can alter behavior, has fueled this push to understand these neurobiological mechanisms. Within this conceptual framework and the funding to incentivize its adoption, the neuroscience field grew rapidly with the goal to understand the relation between the brain and behavior. As such, a reductionist perspective emerged whereby neural manipulations of increasing sophistication became required for assessing …

Attachment Anxiety And Avoidance Predict Postnatal Partner Support Through Impaired Affective Communication, Frances C. Calkins, Rebecca L. Brock

Department of Psychology: Faculty Publications

Objective: The purpose of the present study was to investigate perceived difficulties in affective communication as a key mechanism linking attachment anxiety and avoidance during pregnancy to the quality of postpartum support received by partners.

Background: During the postpartum period, partner support has the potential to promote family well-being by mitigating stress related to changes experienced during this transition. Attachment security is one of the most robust predictors of intimate relationship processes and impacts partner communication and support dynamics.

Method: Heterosexual couples (N = 159) completed surveys and semi-structured interviews to obtain measures of attachment security, perceived difficulties in …

Political Identity Biases Americans’ Judgments Of Outgroup Emotion, Ruby Basyouni, Nicholas R. Harp, Ingrid J. Haas, Maital Neta

Department of Psychology: Faculty Publications

Social group identity plays a central role in political polarization and inter-party conflict. Here, we use ambiguously valenced faces to measure bias in the processing of political ingroup and outgroup faces, while also accounting for interparty differences in judgments of emotion at baseline. Participants identifying as Democrats and Republicans judged happy, angry, and surprised faces as positive or negative. Whereas happy and angry faces convey positive and negative valence respectively, surprised faces are ambiguous in that they readily convey positive and negative valence. Thus, surprise is a useful tool for characterizing valence bias (i.e., the tendency to judge ambiguous stimuli …

Is The Risk For Sexual Revictimization Cumulative? A Prospective Examination, Anna E. Jaffe, Alexandra N. Brockdorf, Terri L. Messman, Kim L. Gratz, David Dilillo

Department of Psychology: Faculty Publications

Introduction: Sexual abuse during childhood is associated with risk for sexual assault as an adult, known as revictimization. Although multiple experiences of sexual assault in adulthood are also common, it is unclear how risk trajectories might continue to evolve in emerging adulthood, defined as ages 18 to 25. Clarifying risk trajectories is important to inform the development of targeted risk reduction interventions. To fill this gap, we examined cumulative risk for sexual assault in emerging adult women following multiple experiences of childhood sexual abuse (CSA) and adulthood sexual assault (ASA).

Methods: Women (n = 447; aged 18–25 years at …

Settler Colonial Origins Of Intimate Partner Violence In Indigenous Communities, Maia C. Behrendt

Department of Sociology: Dissertations, Theses, and Student Research

Indigenous women in the United States experience disproportionately higher rates of intimate partner violence (IPV) compared to their non-Indigenous counterparts. Through a framework of settler colonialism, this article examines how settler colonial gender practices disrupted and eroded generational patterns of gender roles and power relationships within Indigenous communities, contributing over time to today's higher levels of IPV perpetrated against Indigenous women. I argue that future research on IPV must attend to the historical, contemporary, and legal impacts of settler colonial policies and laws that contribute to increased rates of violence within marginalized and racialized communities. In this article, I first …

Wasted Intuitions: New York City’S Solid Waste Management System And The Ambiguous Effects Of Traditional Collective Good Provision Analysis, Andrew Asplin

Honors Program: Senior Projects (Public)

Refuse Collection services' status as a public good has been highly contested. As it is both rivalrous and excludable, basic theory predicts that private provision of solid waste management services will be more efficient. Private trash carters are able to specialize in a way that municipality-run services simply cannot. New York City is unique in that its solid waste management system is rigidly split: residential trash is managed by the city; commercial trash is managed by private businesses. This thesis explores how New York City's public and private solid waste management systems complicate these initial intuitions through a welfare analysis. …

Safety Splash: Pool Safety For Children And Adults, Rachel Lofton

Honors Program: Senior Projects (Public)

This outreach project was made to address the issue of too many children drowning at pools due to a lack of water safety education. The dissemination of pool safety education is imperative to reduce accidental injuries and drownings. The goal of the Safety Splash video and supplemental materials is to provide pool safety education for children and adults. By encouraging conversations between children and adults before going to the pool, there can be an intervention that reduces the risk of injury and drowning once they arrive. Through research, I compiled information to support the effectiveness of a combination video, pamphlet, …

The Green Wave: Effects Of Legal Marijuana On The Labor Market., Sara Varon

Honors Program: Senior Projects (Public)

In this paper I examine the relationship between the introduction of recreational marijuana laws and the labor market. First, using Google Trends data I find evidence that states that undergo the treatment of recreational marijuana legalization will likely experience a large and significant increase in search volume terms related to marijuana demand following the implementation of marijuana regulations. Using this same data set, I find support for the theory that as marijuana legalization becomes more entrenched within each individual state, public interest for marijuana also increases which allows for the use of Google Trends data as a proxy for legalization …

Biochar: Properties And Potential Benefits For Agricultural Soil In Rwanda, Andromede Uwase

Honors Program: Senior Projects (Public)

Physical and chemical soil degradation is becoming a major challenge for agricultural productivity in Rwanda, which is the most important part of the country’s economy. The wide spreading soil degradation in Rwanda is mainly a result of naturally poor soils coupled with unsustainable soil management leading to, for example, accelerated soil erosion, acidification, nutrient loss, compaction, and to decreasing yields. Biochar, as an end product of pyrolysis of biomass in the absence of oxygen, has been proposed as a soil amendment in remediation strategies because of its positive effects on soil productivity relevant parameters such as soil pH, structure, nutrient …

The Relation Between Childhood Maltreatment And Marriage Quality In Adulthood, Melanie Wagner

Honors Program: Senior Projects (Public)

Childhood maltreatment poses the potential for lasting effects on survivors as they enter adulthood. Research lacks investigations into these potential effects, such as the impact on interpersonal relations. This study investigates the correlation between different types of childhood maltreatment and overall quality of marriage, as well as aims to identify which type of childhood maltreatment may be the strongest relative predictor of marital quality. Analyses on a newlywed dataset from Lancaster County, NE yielded results of a strong negative association between measures of childhood maltreatment and marital quality through the application of the Childhood Trauma Questionnaire and the Quality of …

The Intersection Of Leadership Identity Development And Meaning-Making Experiences In College Students, Tori Pedersen

Honors Program: Senior Projects (Public)

The current study explored the intersection of meaning-making with leadership identity development through a narrative lens. Phenomenological interviews were conducted with six senior college students who participate in a leadership mentoring program. Results showed there are six themes of meaning-making experiences that influence leadership identity development: : (a) Confidence, (b) Growth From Challenges, (c) Identity, (d) Influence by Others, (e) Influencing Others, and (f) Involvements. These findings encourage the practice of developing leadership development curricula based upon these themes to further develop leadership identity in students.

Wheat Transcriptomic Responses To Extended Feeding By Wheat Curl Mites, Lise Pingault, Tran Kim Ngan Luong, Joe Louis, Gary Hein

Department of Entomology: Faculty Publications

The economic importance of wheat and its contribution to human and livestock diets has been already demonstrated. However, wheat production is impacted by pests that induce yield reductions. Among these pests, wheat curl mite (WCM, Aceria tosichella Keifer) impacts wheat all around the world. WCM are tiny pests that feed within the whorl of developing leaves, and their feeding causes leaf curling by preventing them from unfurling. The curling of the leaves provides a protective niche for the WCM. Additionally, WCM are also the vector of serious viruses in wheat. Little is known regarding the impact of the WCM on …

Evaluation Of Settling Chamber Hydraulic Retention Time In A Sunshine Bass Biofloc Production System, Bartholomew W. Green, Candis L. Ray

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

High total suspended solids (TSS) concentrations that result from the high feeding rates used in biofloc technology production systems can negatively impact fish performance. Excess TSS are removed from biofloc production tanks by side-stream settling chambers. The effects on solids removal, water quality dynamics, and performance of sunshine bass (female white bass Morone chrysops x male striped bass M. saxatilis) from three settling chamber hydraulic retention times (HRTs; 18, 43, and 87 min; designated HRT18, HRT43, and HRT87, respectively) were evaluated in this 126-d study in biofloc tanks. Corresponding settling chamber flow rates were 7.2, 3.0, and 1.5 …

A Life-Course Perspective Of Sex Trafficking Among The Bedia Caste Of India, Rochelle L. Dalla, Kaitlin Roselius, Victoria J. Johnson, Jessie Peter, Trupti Jhaveri Panchal, Ramani Ranjan, Mrinalini Mischra, Sagar Sahu

Department of Child, Youth, and Family Studies: Faculty Publications

Thousands of Indian women and girls enter the commercial sex industry (CSI) annually based solely on membership in particular castes (e.g., Bedia, Nat). CSI-involved females bear the burden of sustaining entire family units on money earned in the sex trade; it is a life-long responsibility with negligible social status or personal indemnity. Based on the life-course developmental theory (Elder, Jr. 1994, 1998) this investigation was intended to examine trafficked women’s experiences within the commercial sex industry across time. Beyond the CSI, we were equally interested in experiences with factors that could promote well-being (i.e., social support) and normative developmental transitions …

Root Exudates Impact Plant Performance Under Abiotic Stress, Yen Ning Chai, Daniel P. Schachtman

Department of Agronomy and Horticulture: Faculty Publications

Plant root exudates serve pivotal roles in supporting plant development and interactions with the physicochemical and biological factors in the rhizosphere. Under stress conditions, root exudation is involved in enhancing plant resource-use efficiency and facilitating the crosstalk between plant and soil microbes to ameliorate stress. Although there are a large number of root exudates that remain to be characterized, recent technological advancements have allowed for the function of many exudate compounds to be elucidated. In this review, we discuss current knowledge about the key root exudates that modulate plant resource-use efficiency under various abiotic stresses including drought, aluminum toxicity, phosphorus, …
