The Influence Of Proximal And Distal Familial Factors On Preschool Children's Inhibitory Control And Social Emotional Skills, Amy Encinger

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

Children in the United States experience higher rates of poverty than any other age group, including elderly adults and the poverty rate of young children (0-5 years) is considerably higher than that of older children (Proctor et al., 2016). There is an extensive body of research examining familial socioeconomic status (SES) and the influence on the skills and behaviors of young children; however, common key indicators of family SES may not fully depict the ways in which children living in poverty/low-income homes are influenced by economic disadvantage. The focus of the current study is to explore the ways in which …

The R package TULIP integrates several popular high-dimensional LDA-based methods and provides a comprehensive and user-friendly toolbox for linear, semi-parametric and tensor-variate classification. Functions are included for model fitting, cross validation and prediction. In addition, motivated by datasets with diverse sources of predictors, we further include functions for covariate adjustment. Our package is …

The Sea Will Rise, Barbuda Will Survive: Environment And Time Consciousness, Sophia Perdikaris

School of Global Integrative Studies: Faculty Publications

In this article, we examine the link between environmental consciousnesses and time consciousness. We argue that the way people think about time shapes their experience of climate change threats. We contrast western hegemonic concepts of time—the Gregorian Calendar, the Dooms Day Clock, linear time—with the way Barbudans of Antigua and Barbuda, an island nation in the Caribbean experience time—cyclical, through boom and bust cycles. We found that this boom and bust framework was indeed supported by climate change and weather experiences on the island—hurricanes, droughts, changes in the lagoons—as well as economic experiences—cargo boat delays bringing supplies, paycheck delays. By …

Other QIC-WD Products

The QIC-WD learned many lessons while conducting utilization-focused workforce research across eight diverse public child welfare agencies. In this brief we detail how we are chronicling natural variation (e.g., stay at home orders, hiring freezes, political will, and leadership changes), synthesizing existing data, conducting process evaluation (e.g., identifying implementation drivers), visualizing data to meet diverse stakeholder information needs, and building systems that are both flexible and sustainable.

Organizational Justice, Tara Myers, Megan Paul

Umbrella Summaries

What is organizational justice?

Organizational justice is the extent to which an organization treats people fairly. Organizational justice includes fairness related to outcomes, procedures, and interpersonal interactions. Fair workplace outcomes and decisions (e.g., equitable/favorable pay, raise, promotion) are called distributive justice (Adams, 1965). Procedural justice means that outcomes are determined through procedures that are based on accurate information and standard ethics, represent everyone affected by the procedure, include opportunity for input and appeal, are free from bias, and are used consistently (Leventhal, 1980; Thibaut & Walker, 1975). Interactional justice refers to people feeling they were treated with dignity and respect …

Race And Ethnic Variation In College Students’ Allostatic Regulation Of Racism-Related Stress, Jacob E. Cheadle, Bridget J. Goosby, Joseph C. Jochman, Cara Tomaso, Chelsea B. Kozikowski Yancey, Timothy D. Nelson

Department of Sociology: Faculty Publications

Racism-related stress is thought to contribute to widespread race/ ethnic health inequities via negative emotion and allostatic stress process up-regulation. Although prior studies document racerelated stress and health correlations, due to methodological and technical limitations, they have been unable to directly test the stress-reactivity hypothesis in situ. Guided by theories of constructed emotion and allostasis, we developed a protocol using wearable sensors and daily surveys that allowed us to operationalize and time-couple self-reported racism-related experiences, negative emotions, and an independent biosignal of emotional arousal. We used data from 100 diverse young adults at a predominantly White college campus to assess …

Promoting Higher Quality Teacher–Child Relationships: The Insights Intervention In Rural Schools, Kathleen Moritz Rudasill, Ray E. Reichenberg, Jungwon Eum, Jentry Stoneman Barrett, Yuenjung Joo, Emily Wilson, Martinique Sealy

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

Children’s relationships with teachers in kindergarten are crucial for academic and social success. Research shows that teacher–child relationships are predicated, in part, on children’s temperament. The “INSIGHTS into Children’s Temperament” intervention was intended to improve children’s and teachers’ understanding of their and others’ temperament, and has been shown to improve children’s social skills and self-regulation in urban, under-resourced schools. The current study is part of a replication of the effects of INSIGHTS with a sample in rural schools. The purpose was to test the effectiveness of INSIGHTS for promoting positive relationships between teachers and children in kindergarten. Two cohorts of …

Point-Of-Decision Prompts Increase Dietary Fiber Content Of Consumers’ Food Choices In An Online Grocery Shopping Simulation, Kristina Arslain, Christopher Gustafson, Devin J. Rose

Department of Food Science and Technology: Faculty Publications

Only 5% of Americans consume the recommended amount of dietary fiber. In an online simulated shopping experiment, we examined whether a fiber-focused point-of-decision prompt (PDP) would influence consumers to choose food products that were higher in this important nutrient. We hypothesized that participants exposed to the dietary fiber PDP would choose products with more dietary fiber/serving than those who were not exposed to the PDP. The experiment was completed by 753 participants. Participants were randomly assigned to a condition in which they were not exposed to a PDP (the no-PDP condition), a personalized PDP, or PDP without personalization. Choices in …

Department of Teaching, Learning, and Teacher Education: Theses and Other Student Research

This study used a cross-sectional survey design in an aim to compare the technology readiness (TR) of hospital-based nurse educators (HBNEs) that use highfidelity simulation (HFS) and those that do not use HFS in order to determine if a difference in TR might account for the lack of widespread adoption of HFS in the hospital setting. An online survey was administered to HBNEs from two national organizations: ANPD and SSH. Descriptive statistics and quantitative data analyses were conducted and reported as well as qualitative findings. Descriptive statistics revealed the average age of HBNE to be 45-46 years of age, possessing …

Career And Technical Education Teachers’ Beliefs About Developing Students’ Motivation To Write, Katie Graham

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

Students in the U.S. write poorly. Although postsecondary and workplace writing expectations continue to rise, writing instruction has largely remained unchanged over time. As a result, student writing outcomes continue to fall below expectations from both an assessment and hirable proficiency standpoint. Career and Technical Education (CTE) provides a unique opportunity to motivate students who are otherwise disengaged in writing (ACTE, 2009). The benefits of helping students develop their writing-self efficacy has well-documented support (Bruning & Horn, 2009; Bandura, 1997; Pajares 2003; Pajares & Valiante, 2006). However, little is known about the writing opportunities provided in CTE classes or CTE …

School of Biological Sciences: Faculty Publications

Student impressions formed during the first day of class can impact course satisfaction and performance. Despite its potential importance, little is known about how instructors format the first day of class. Here, we report on observations of the first day of class in 23 introductory science, technology, engineering, and math (STEM) courses. We first described how introductory STEM instructors structure their class time by characterizing topics covered on the first day through inductive coding of class videos. We found that all instructors discussed policies and basic information. However, a cluster analysis revealed two groups of instructors who differed primarily in …

Assessment Centers, Tara Myers, Megan Paul

Umbrella Summaries

What are assessment centers?

Assessment centers measure knowledge, skills, abilities, and other characteristics by assessing participants’ responses to job-related simulations. Assessment centers can be used for hiring, placement, and career and skill development (Gaugler, Rosenthal, Thornton, and Bentson, 1987). Typically, participants complete a combination of in-basket, leaderless group discussion, role play, case analysis, and oral presentation exercises (Hoffman, Kennedy, LoPilato, Monahan, and Lance, 2015). Within each exercise, participants review job-relevant information and complete tasks. For the in-basket, participants are presented with documents (e.g., emails, memos, reports, requests—things that might be in an inbox) to which they provide responses and about …

Developing A Computer-Controlled Treat Dispenser For Canine Operant Conditioning, Walker Arce, Jeffrey R. Stevens

Center for Brain, Biology, and Behavior: Faculty Publications

When performing canine operant conditioning studies, the delivery of the reward can be a limiting factor of the study. While there are a few commercially available options for automatically delivering rewards, they generally require manual input, such as using a remote control, in accordance with the experiment script. This means that human reaction times and transmission distances can cause interruptions to the flow of the experiment. The potential for development of non-supervised conditioning studies is limited by this same factor. To remedy this, we retrofitted an off-the-shelf treat dispenser with new electronics that allow it to be remotely controllable as …

Interval Estimation Of Proportion Of Second-Level Variance In Multi-Level Modeling, Steven Svoboda

The Nebraska Educator: A Student-Led Journal

Physical, behavioral and psychological research questions often relate to hierarchical data systems. Examples of hierarchical data systems include repeated measures of students nested within classrooms, nested within schools and employees nested within supervisors, nested within organizations. Applied researchers studying hierarchical data structures should have an estimate of the intraclass correlation coefficient (ICC) for every nested level in their analyses because ignoring even relatively small amounts of interdependence is known to inflate Type I error rate in single-level models. Traditionally, researchers rely upon the ICC as a point estimate of the amount of interdependency in their data. Recent methods utilizing an …

Ohio Progress Update- Addressing Secondary Traumatic Stress And Providing Supportive Supervision, Quality Improvement Center For Workforce Development

Other QIC-WD Products

Secondary traumatic stress (STS) refers to the experience of people – generally professionals– who are exposed to others’ traumatic stories as part of their work. As a result of this exposure, these professionals can develop their own traumatic symptoms and reactions. Child welfare staff are particularly susceptible to STS because of the vulnerable nature of the families they work with, the unpredictable nature of their jobs, and their general lack of physical and psychological protection (ACS-NYU Children’s Trauma Institute, 2011). As such, STS can mimic the symptoms of Post-Traumatic Stress Disorder (Bride, 2007) including nightmares, sleep disruption, avoidance, and irritability. …

Developing A Model Of Graduate Teaching Assistant Teacher Efficacy: How Do High And Low Teacher Efficacy Teaching Assistants Compare?, Cody R. Smith, Cesar Delgado

School of Natural Resources: Faculty Publications

Graduate teaching assistants (TAs) are often responsible for teaching introductory courses to undergraduate science, technology, engineering, and mathematics students. The TAs are usually novices at teaching, and an important factor in their resilience and persistence in the face of inevitable challenges is self-efficacy. Little is known about what affects TA teacher efficacy or whether and how high- and low-efficacy TAs differ in their development as teachers. Bridging these gaps in the literature will inform best practices in developing and implementing professional development (PD) for TAs. Using a mixed-methods sequential exploratory research design, this study found differences in high- and low-efficacy …

Schoolgirl Embroideries & Black Girlhood In Antebellum Philadelphia, Kelli Racine Coles

Textile Society of America: Symposium Proceedings

Embroideries stitched by girls at schools for Black children in the eighteenth and nineteenth centuries are rare finds in the antiques world. The few embroideries likely stitched by Black schoolgirls that do survive often offer historical evidence in the form of the names of their makers’ schools stitched onto their embroideries. Yet there is little scholarship on these embroideries or the education these schoolgirls were pursuing while creating their samplers. In scholarship using material culture as primary evidence, these embroideries provide valuable clues about the lives of Black girls in northern cities during the antebellum period. My work examines the …
