Effects Of Separation On The Immigrant Family, Mainor Ramirez

Nebraska College Preparatory Academy: Senior Capstone Projects

In the United States of America, deportation has always been an issue, becoming a greater issue in today’s society. Deportation can be defined as a lawful expulsion of a person from a country. Many families have come to the U.S. in the hope of a brighter and better future, but that is not always the case. Constantly running in fear of the Immigration and Customs Enforcement (ICE), they struggle to survive in a land of unknown. What many people do not know are the reasons why families come to the U.S and the effects deportation has on children when they …

The Effect Of Agkistrodon Contortrix And Crotalus Horridus Venom Toxicity On Strike Locations With Live Prey, Chase Giese

Department of Environmental Studies: Undergraduate Student Theses

This paper aims to uncover if there is a significant difference in the strike location of snake species that have different values of LD50% venom. It is thought that most snakes strike their prey in the anterior (head) area in order for their venom to work quicker in killing them. Venom toxicity is measured by its LD50% value, which is the amount of venom, in mg/kg, to kill 50% of a test population. The Copperhead has an LD50% value of 10.9 mg/kg, and the Timber Rattlesnake has an LD50% value of 1.64 mg/kg. The hypothesis was that if venom toxicity …

Overview Of The Insect Food And Feed Industry, Daniel J. Seckman

Department of Entomology: Distance Master of Science Projects

The entomophagy field is one that when you immerse yourself in it, you will feel like the entire world is talking about insects as food and feed. Yet, from the outside, the industry is virtually nonexistent. In the United States, the North American Coalition for Insect Agriculture (NACIA) is the leading organization dedicated to growing the insect food and feed sector. While the organization has grown extensively in recent years, most individuals in the food, feed, and entomological industry have never heard of the organization. The Wall Street Journal presents the annual Food Forum, which aims to “tackle the critical …

The Relationship Between Bodyweight Status And Weight Perception Explains Differences In Calories Ordered In A Food Choice Exercise, Jean-Claude Mbarushimana, Christopher Gustafson, Henriette Gitungwa, Eliana Zeballos

Department of Agricultural Economics: Faculty Publications

Understanding food choice is critical to be able to address the rise in obesity rates around the globe. In this paper, we examine the relationship between measured (BMI, using self-reported height and weight) and perceived weight status with the number of calories ordered in a controlled online food choice exercise. A total of 1044 participants completed an online food choice exercise in which they selected ingredients for a sandwich from five categories: meat/protein, cheese, spread/dressing, bread, and vegetables. We examine the number of calories ordered by participants and use linear regression to study the relationship of BMI category relative to …

Shaping The Teaching And Learning Of Intercultural Communication Through Virtual Mobility, Theresa Catalano, Andrea Muñoz Barriga

Department of Teaching, Learning, and Teacher Education: Faculty Publications

The globally mobile reality of today’s world has made the field of intercultural communication increasingly relevant as people more often find themselves in intercultural situations. As a result, language teachers must be more prepared to work in intercultural contexts, and to teach their own students how to communicate across differences in intercultural situations both physically and virtually. The present paper examines this special issue’s topic of physical and virtual mobility and intercultural competence through the lens of teacher education. Using narrative inquiry, two teacher educators in very different geographic and socio-economic contexts (US and Colombia) explore their own attempts at …

Department of Teaching, Learning, and Teacher Education: Faculty Publications

The purpose of this qualitative study was to investigate preservice elementary teachers’ science teacher identity development during their participation in the field-based science methods course and a year after. Grounded within the Feiman-Nemser’s thematic framework of learning to teach, this study utilized a case study approach aimed to examine the experiences that contributed to formation of science teacher identities of two participants uniquely positioned in the teacher education programs at the two sites, USA and Canada. Data collected over a year included science autobiographies, reflective journals, interviews, classroom observations, and artifacts. The analysis of the data revealed that experiences and …

Immigrant Background Students’ Names And Identities In U.S. Schools: Voices From The Underground, Lydiah Kananu Kiramba

Department of Teaching, Learning, and Teacher Education: Faculty Publications

This poem is a recreation of conversational interviews with five immigrant background adolescent African girls (Pendo, Furaha, Amani, Faraja, and Neema), all names are pseudonyms. In those interviews, the girls continuously shared how important their names are for them and the challenges they encountered with teachers and peers mispronouncing their names. One student mentioned taking time to teach her teachers, but was often told, “It’s just a name.” Weird gazes on her teachers’ faces are the best pronunciation she had received. This free verse poem speaks to the relationship between students’ individual names and identities, biases—which are often based on …

Cultural And Linguistic Experiences Of Immigrant Youth: Voices Of African Immigrant Youth In United States Urban Schools, Lydiah Kananu Kiramba, Alex Kumi-Yeboah, Patriann Smith, Anthony Mawuli Sallard

Department of Teaching, Learning, and Teacher Education: Faculty Publications

This study explores experiences of 50 culturally and linguistically diverse African immigrant students attending public urban middle and high schools in the US. Drawing on in-depth interviews, and through constant comparison analysis, emerging findings highlight pedagogical, linguistic, and curricular variation struggles in the classroom; transitional contextual challenges; cultural mismatch; miscommunication, and stereotypes. In light of these experiences, African immigrant urban youth draw on familial, navigational and aspirational capital to resist stereotypical assumptions and to develop resilient skills necessary to navigate the inherent challenges. Findings underscore the importance of appreciating ways of knowing that deviate from the host country knowledges as …

Censored Data Considerations And Analytical Approaches For Salivary Bioscience Data, Hedyeh Ahmadi, Douglas A. Granger, Katrina R. Hamilton, Clancy Blair, Jenna L. Riis

Department of Psychology: Faculty Publications

Left censoring in salivary bioscience data occurs when salivary analyte determinations fall below the lower limit of an assay’s measurement range. Conventional statistical approaches for addressing censored values (i.e., recoding as missing, substituting or extrapolating values) may introduce systematic bias. While specialized censored data statistical approaches (i.e., Maximum Likelihood Estimation, Regression on Ordered Statistics, Kaplan-Meier, and general Tobit regression) are available, these methods are rarely implemented in biobehavioral studies that examine salivary biomeasures, and their application to salivary data analysis may be hindered by their sensitivity to skewed data distributions, outliers, and sample size. This study compares descriptive statistics, correlation …

Factors Associated With Smoking In Low-Income Persons With And Without Chronic Illness, Monique T. Cano, David L. Pennington, Sara Reyes, Blanca S. Pineda, Jazmin Llamas, Vyjeyanthi S. Periyakoil, Ricardo F. Muñoz

Department of Psychology: Faculty Publications

INTRODUCTION Tobacco disparities persist among low-income smokers who seek care from safety-net clinics. Many of these patients suffer from chronic illnesses (CILs) that are associated with and exacerbated by smoking. The objective of the current study was to examine the differences between safety-net patients with and without CILs in terms of nicotine dependence and related factors (such as depression, anxiety) and self-efficacy regarding ability to abstain from smoking. METHODS Sixty-four low-income smokers who thought about or intended to quit smoking were recruited from the San Francisco Health Network (SFHN) and assessed for CILs, nicotine dependence, depression, anxiety, and smoking abstinence …

Probabilistic Mapping Of Human Functional Brain Networks Identifies Regions Of High Group Consensus, Ally Dworetsky, Benjamin A. Seitzman, Babatunde Adeyemo, Maital Neta, Rebecca S. Coalson, Steven E. Petersen, Caterina Gratton

Department of Psychology: Faculty Publications

Many recent developments surrounding the functional network organization of the human brain have focused on data that have been averaged across groups of individuals. While such group-level approaches have shed considerable light on the brain’s large-scale distributed systems, they conceal individual differences in network organization, which recent work has demonstrated to be common and widespread. This individual variability produces noise in group analyses, which may average together regions that are part of different functional systems across participants, limiting interpretability. However, cost and feasibility constraints may limit the possibility for individual-level mapping within studies. Here our goal was to leverage information …

A Comprehensive Study To Delineate The Role Of An Extracellular Vesicle-Associated Microrna-29a In Chronic Methamphetamine Use Disorder, Subhash Chand, Austin Gowen, Mason Savine, Dalia Moore, Alexander Clark, Wendy Huynh, Niming Wu, Katherine Odegaard, Lucas Weyrich, Rick A. Bevins, Howard S. Fox, Gurudutt Pendyala, Sowmya V. Yelamanchili

Department of Psychology: Faculty Publications

Extracellular vesicles (EVs), which express a repertoire of cargo molecules (cf. proteins, microRNA, lipids, etc.), have been garnering a prominent role in the modulation of several cellular processes. Here, using both non-human primate and rodent model systems, we provide evidence that brain-derived EV (BDE) miRNA, miR- 29a-3p (mir-29a), is significantly increased during chronic methamphetamine (MA) exposure. Further, miR-29a levels show significant increase both with drug-seeking and reinstatement in a rat MA self-administration model. We also show that EVassociated miR-29a is enriched in EV pool comprising of small EVs and exomeres and further plays a critical role in MA-induced inflammation and …

A New Tool For Equating Lexical Stimuli Across Experimental Conditions, Evan N. Lintz, Phui Cheng Lim, Matthew R. Johnson

Department of Psychology: Faculty Publications

In cognitive psychology and psycholinguistics, lexical characteristics can drive large effects, which can create confounds when word stimuli are intended to be unrelated to the effect of interest. Thus, it is critical to control for these potential confounds. As an alternative to randomly assigning word bank items to stimulus lists, we present LIBRA (Lexical Item Balancing & Resampling Algorithm), a MATLAB-based toolbox for quickly generating stimulus lists of user-determined length and number that can be closely equated on any number of lexical properties. The toolbox comprises two scripts: a genetic algorithm that performs the inter-list balancing, and a tool for …

Does Self-Objectification Entail An Opposition Between Appearance And Competence? The Likert Version Of The Self-Objectification Questionnaire (Lsoq), Robin Wollast, Oliver Klein, Dawn M. Vanleeuwen, Sarah J. Gervais, Philippe Bernard

Department of Psychology: Faculty Publications

We propose a new method to test the reliability of Fredrickson et al.’s self-objectification questionnaire (SOQ). This scale being based on a ranking, traditional reliability estimates are inappropriate. Based on generalizability theory, we suggest to compute the reliability of each subset of questions related to physical appearance vs. physical competence separately in order to average them. We applied this method to a sample of female US undergraduates (n = 395) and evidenced that the reliability of the scale is very low (corrected Cronbach’s alpha = .31). We also noted that a large proportion of the sample (32%) failed to …

An Examination Of The Relations Between Emotion Dysregulation, Dissociation, And Self-Injury Among Dissociative Disorder Patients, M. Shae Nester, Bethany L. Brand, Hugo J. Schielke, Shaina Kumar

Department of Psychology: Faculty Publications

Background: Dissociative disorder (DD) patients report high rates of self-injury. Previous studies have found dissociation and self-injury to be related to emotional distress. To the best of our knowledge, however, the link between emotion dysregulation and self-injury has not yet been examined within a DD population. Objective: The present study investigated relations between emotion dysregulation, dissociation, and self-injury in DD patients, and explored patterns of emotion dysregulation difficulties among DD patients with and without recent histories of self-injury. Method: We utilized linear and logistic regressions and t-test statistical methods to examine data from 235 patient-clinician dyads enrolled …

Trust In The Jury System: A Comparison Of Australian And U.S. Samples, Monica K. Miller, Jeffrey Pfeifer, Brian H. Bornstein, Tatyana Kaplan

Department of Psychology: Faculty Publications

Public trust in the criminal justice system, including the jury system, is important for maintaining a democracy that is fair for all citizens. However, there is little research on trust in the jury system generally and even less cross-country comparison research specifically. Trust in the jury system might relate to other legal attitude measures (e.g., authoritarianism). This study identified the degree to which trust in the jury system relates to legal attitudes and compared perceptions of trust between the U.S. and Australia. Community members completed a survey that included measures of trust in the jury system and legal attitudes. The …

The Truth About Snitches: An Archival Analysis Of Informant Testimony, Jeffrey S. Neuschatz, Danielle K. Deloach, Megan A. Hilgartner, Melanie Fessinger, Stacy A. Wetmore, Amy B. Douglass, Brian H. Bornstein, Alexis M. Le Grand

Department of Psychology: Faculty Publications

Informants are witnesses who often testify in exchange for an incentive (i.e. jailhouse informant, cooperating witness). Despite the widespread use of informants, little is known about the circumstances surrounding their use at trial. This study content-analyzed trials from 22 DNA exoneration cases involving 53 informants. Because these defendants were exonerated, the prosecution informant testimony is demonstrably false. Informant characteristics including motivation for testifying, criminal history, relationship with the defendant and testimony were coded. Most informants were prosecution jailhouse informants; however, there were also defence jailhouse informants and prosecution cooperating witnesses. Regardless of informant type, most denied receiving an incentive, had …

Political Uncertainty Moderates Neural Evaluation Of Incongruent Policy Positions, Ingrid J. Haas, Melissa N. Baker, Frank J. Gonzalez

Center for Brain, Biology, and Behavior: Faculty Publications

Uncertainty has been shown to impact political evaluation, yet the exact mechanisms by which uncertainty affects the minds of citizens remain unclear. This experiment examines the neural underpinnings of uncertainty in political evaluation using functional magnetic resonance imaging (fMRI). During fMRI, participants completed an experimental task where they evaluated policy positions attributed to hypothetical political candidates. Policy positions were either congruent or incongruent with candidates’ political party affiliation and presented with varying levels of certainty.Neural activitywas modelled as a function of uncertainty and incongruence. Analyses suggest that neural activity in brain regions previously implicated in affective and evaluative processing (anterior …

Association Between Sleep Quality And Dorsal Default Mode Network In College Students, Anna Klets

College of Education and Human Sciences: Dissertations, Theses, and Student Research

College students often have poor sleep quality, which may change resting state functional connectivity network in the brain. Prior research demonstrated that sleep is associated with structural and functional changes in some specific brain subareas, which are involved in the dorsal default mode network (dDMN). However, no study to date has comprehensively examined all possible individual pairs of functional connectivity in the dDMN in relation to sleep quality among college students. Therefore, the present study hypothesized that sleep quality in college students was linked to any resting state functional connectivity in the dDMN.

Forty nine college students (25 females) underwent …

Protective Factors Against Dating Violence Perpetration And Victimization, Meagan Kunitzer

Department of Sociology: Dissertations, Theses, and Student Research

Dating violence is a prominent problem among college students that can result in harmful physical and mental health outcomes. To date, much research has focused on risk factors, but less is known about protective factors that may decrease the likelihood of dating violence. As such, the current paper examines protective factors (e.g. religion, positive parental relationships) against perpetrating and/or experiencing dating violence and whether these protective factors operate similarly for both perpetration and victimization. Data were gathered in 2013-2014 at two large public universities using pencil and paper surveys (N = 1482). Bivariate results revealed that women have more protective …

Housework: Socialization Influences On Individual Performance, Couple Division Of Labor And Mental Health, Jaala Robinson

Department of Sociology: Dissertations, Theses, and Student Research

Despite the continued gender inequality in the division of housework, little research has considered how family housework socialization influences the amount of housework a person performs and their mental health. Socialization processes occur via the amount of housework performed in the home during childhood by each parent and the parents’ gender division of household labor. This analysis details three studies that explore the impact of socialization to housework. All three studies take advantage of intergenerational data from the Panel Study of Income Dynamics (PSID). The first study uses a social learning framework to test whether the amount of housework a …

Individual Differences In Social Responsiveness, Social Experiences, And Oxytocin System Genetic Variation In Depression Symptom Severity, Grace Sullivan

Department of Psychology: Dissertations, Theses, and Student Research

Social experiences including discrimination, low social support, and interpersonal conflict are reliable predictors of depression symptom severity (Costello, 1982; Monroe, Rohde, Seeley, & Lewinsohn, 1999; Phifer & Murrell, 1986). However, individual differences may buffer against or exacerbate risk (Pluess & Belsky, 2015). A more holistic and dimensional approach, in line with modern perspectives on mental health (Kircanski, LeMoult, Ordaz, & Gotlib, 2017), requires an investigation of individual differences that moderate associations of positive and negative social experiences with depression symptom severity. This dissertation assesses relative contributions of social experiences (low social support, discrimination, childhood trauma, and sexual objectification) to variation …

Honors Program: Senior Projects (Public)

With an aggressive goal of 25% growth in both the Tree City USA and Tree Campus Higher Education programs, the Arbor Day Foundation (“ADF”, “Arbor Day”) needs a correspondingly bold plan to follow. Our group’s set of recommendations keep in step with ADF’s goals of inspiring people to Plant, Nurture, and Celebrate trees. Adopting ADF’s guiding principles informed and refined our recommendations. Our suggestions to ADF are to expand and refine marketing objectives, make use of communication platforms, streamline the survey and application procedure, and restructure the Tree City participation incentive programs. The subsections of this report provide greater detail …

(Non)Religious Coping With A Natural Disaster In A Rural U.S. Community, Dena Abbott, Andrew Franks, Corey Cook, Caitlin Mercier

Department of Educational Psychology: Faculty Publications

Religious/spiritual (R/S) coping following natural disasters is associated with positive outcomes, leading to perceptions that the absence of R/S coping leads to negative outcomes among nonreligious individuals. However, little research explicitly explores the coping strategies of nonreligious individuals in response to natural disasters and traumatic events. The present study collected data from a sample of survivors of a natural disaster event (i.e., a tornado) to test the relationship between (non)religiosity/(non)spirituality, coping, psychological distress, and posttraumatic growth. Statistical models suggested that problem-focused coping facilitated posttraumatic growth and lower levels of psychological distress among people with lower levels of institutional religiousness and/or …

Transference Of Citizen Science Program Impacts: A Theory Grounded In Public Participation In Scientific Research, Louise I. Lynch-O’Brien

Department of Entomology: Faculty Publications

Citizen science is known for increasing the geographic, spatial, and temporal scale from which scientists can gather data. It is championed for its potential to provide experiential learning opportunities to the public. Documentation of educational outcomes and benefits for citizen scientists continues to grow. This study proposes an added benefit of these collaborations: the transference of program impacts to individuals outside of the program. The experiences of fifteen citizen scientists in entomology citizen science programs were analyzed using a constructivist grounded theory methodology. We propose the substantive-level theory of transference to describe the social process by which the educational and …

Doing Assessment: A Multicase Study Of Preschool Teachers’ Language And Literacy Data Practices, Rachel E. Schachter, Shayne B. Piasta

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

Early childhood research and policy have promoted the use of language and literacy assessment data to inform instruction. Yet, there is a limited understanding of preschool teachers’ data practices and sensemaking, particularly when considered from the perspectives of practicing teachers. In this multicase study, we used a phenomenological approach to generate a theory about preschool teachers’ data practices in relation to supporting children’s language and literacy outcomes. Twenty preschool teachers participated in a series of three observations, planning interviews, and stimulated recall interviews designed to tap their pedagogical reasoning and data use practices. The framework that emerged through iterative within-and …

Sensitray: An Integrated Measuring Device For Monitoring Children’S Mealtime Dietary Intake, Hunter S. Guru, Anthony D. Weng, Santosh Pitla, Dipti Dev

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

Childhood nutrition establishes consumption norms that affect an individual’s health over the course of their lives. However, early nutrition interventions to establish such norms are uncommon owing to the various inefficiencies associated with current methods of measuring childhood nutrition. Here, we present an IoT measuring device, called the SensiTray, which accurately tracks mealtime intake in a child-friendly and cost-effective fashion. Principal technologies underlying the SensiTray (including mass-sensing technologies, microcontrollers) are identified and analyzed, along with other design choices. Operation of the SensiTray is explained with special attention given to SensiTray software peripherals and algorithms. Preliminary testing consisted of static and …

Spring Break Or Heart Break? Extending Valence Bias To Emotional Words, Nicholas R. Harp, Catherine C. Brown, Maital Neta

Department of Psychology: Faculty Publications

Ambiguous stimuli are useful for assessing emotional bias. For example, surprised faces could convey a positive or negative meaning, and the degree to which an individual interprets these expressions as positive or negative represents their “valence bias.” Currently, the most well- wellvalidated ambiguous stimuli for assessing valence bias include nonverbal signals (faces and scenes), overlooking an inherent ambiguity in verbal signals. This study identified 32 words with dual-valence ambiguity (i.e., relatively high intersubject variability in valence ratings and relatively slow response times) and length-matched clearly valenced words (16 positive, 16 negative). Preregistered analyses demonstrated that the words-based valence bias correlated …
