Constraints To Waterfowl Hunting By Hunters And Anglers In The Central United States, Matthew P. Hinrichs, Matthew P. Gruntorad, Julia A. Nawrocki, Mark P. Vrtiska, Mark A. Pegg, Christopher J. Chizinski

School of Natural Resources: Faculty Publications

Waterfowl hunting participation has been on the decline since the mid‐1980s. We used a web‐based survey to better understand waterfowl hunting constraints (i.e., factors that limit or prohibit participation and enjoyment in leisure activities) among hunters and anglers that hunted or did not hunt waterfowl in the central United States. Forty‐eight constraint items were condensed into 10 constraint factors: Rules and Regulations, Waterfowl Identification, Cost, Waterfowl Hunting Skills, Land Access and Permissions, Interference by Other Hunters, Travel, Social, Waterfowl Populations, and Views of Others. We observed significant effects of both state of residence and activity type (i.e., frequent waterfowl hunters, …

Adrenocortical Attunement, Reactivity, And Potential Genetic Correlates Among Parent-Daughter Dyads From Low-Income Families, Jennifer Byrd-Craven, Michael M. Criss, Jessica L. Calvi, Lixian Cui, Amanda Baraldi, Amanda Sheffield Morris

Athletic Performance Research

Examining the multitude of influences on the development of adolescent stress responses, especially among low-income families, is a critical and understudied topic in the field. The current study examined cortisol attunement between adolescent girls and parents (mostly mothers) from predominantly low-income, single parent, ethnic minority families before and after an in-laboratory disagreement discussion task. The sample consisted of 118 adolescents (M_age = 13.79 years, 76.3% ethnic minorities, 23.7% European Americans) and primary caregivers (M_age = 40.62 years; Mdn yearly income = $24,000; 43.2% single parents; 50% living below poverty line). We investigated oxytocin receptor (OXTR rs53576) …

Passed: Calculate Power And Sample Size For Two Sample Tests, University Of Missouri Li, Ryan P. Knigge, Kaiyi Chen, Emily V. Leary

The R Journal

Power and sample size estimation are critical aspects of study design to demonstrate minimized risk for subjects and justify the allocation of time, money, and other resources. Researchers often work with response variables that take the form of various distributions. Here, we present an R package, PASSED, that allows flexibility with seven common distributions and multiple options to accommodate sample size or power analysis. The relevant statistical theory, calculations, and examples for each distribution using PASSED are discussed in this paper.

Cat.Dt: An R Package For Fast Construction Of Accurate Computerized Adaptive Tests Using Decision Trees, Javier Rodríguez-Cuadrado, Juan C. Laria, David Delgado-Gómez

The R Journal

This article introduces the cat.dt package for the creation of Computerized Adaptive Tests (CATs). Unlike existing packages, the cat.dt package represents the CAT in a Decision Tree (DT) structure. This allows building the test before its administration, ensuring that the creation time of the test is independent of the number of participants. Moreover, to accelerate the construction of the tree, the package controls its growth by joining nodes with similar estimations or distributions of the ability level and uses techniques such as message passing and pre-calculations. The constructed tree, as well as the estimation procedure, can be visualized using the …

Votes And Voters In Time And Space: The Changing Landscape Of Political Party Support In Kentucky, 1974–2020, Glenn Humphress

Department of Geography: Dissertations, Theses, and Student Research

This research examines the time-series geography of voter registrations, presidential elections, senatorial elections, and gubernatorial elections within Kentucky during the period from 1974 to 2020 to explore the dimensions of a changing geography of political party support. During this time Kentucky realigned from strong election support for the Democratic Party to consistent election support for the Republican Party. Using graphs, Dissimilarity Indices, cartographic analysis, and factor analysis, this study confirms aspects of intra-state sectionalism and periodization in election results identified in previous research but finds different characteristics of section and period in voter registrations. In effect this study finds support …

Students' Definitions Of Academic Success, Brent Kelderman

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

Academic success has not been well defined consistently, and when definitions have been proposed (e.g. Kuh, Kinzie, Buckley, Bridges, & Hayek, 2006 ; York, Gibson, & Rankin, 2015), they are not always measured consistently. Is it good grades (Parker, Summerfeldt, Hogan, & Majeski, 2004), and if so, what constitutes a good grade and what should be graded? Is it understanding the material, and if so, is understanding shown by simply completing the academic tasks (Choi, 2005)? Is it perseverance and grit (Tang, Wang, Guo, & Salmela-Aro, 2019), and if so, why do many other definitions and views focus so much …

The Importance Of Acquisition Learning On Nicotine And Varenicline Drug Substitution In A Drug-Discriminated Goal-Tracking Task, Brady M. Thompson, Scott T. Barrett, Y. Wendy Huynh, David A. Kwan, Jennifer E. Murray, Rick A. Bevins

Department of Psychology: Faculty Publications

Nicotine and varenicline (Chantix®; the leading non-nicotine cessation pharmacotherapy) can come to control appetitive behaviors such as goal-tracking. We tested rats (N = 48) in a drug-discriminated goal-tracking (DGT) task where each rat received daily subcutaneous injections of either nicotine (0.4 mg/kg) or saline (0.9% [w/v]) interspersed across the acquisition phase (Phase 1). On saline days, sucrose was intermittently available. On nicotine days, sucrose was withheld. All rats acquired the discrimination with increased goal-tracking rates on saline days relative to nicotine days. Following acquisition, rats were separated into four groups to assess drug-substitution and discrimination reversal in Phase 2. The …

Statistical Mediation Analysis In Regression Discontinuity Design For Causal Inference, Donna Chen

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

Regression discontinuity designs (RDDs) are the most robust quasi-experimental design, but current statistical models are limited to estimates for the simple causal relationship between only two variables: the independent and dependent variables. In practice, intervening variables (or mediators) are often observed as part of the causal chain. Mediators explain the why and how a treatment or intervention works. Therefore, mediation and RDD analysis combined can be a useful tool in identifying key components or processes that make intervention programs effective while making causal inferences for improving student achievement, despite natural constraints, limitations, and ethical considerations. Without an integrated framework of …

An Intersectionality Framework On The Role Of Student-Teacher Relationships On Student Social Outcomes, Kenji Madison

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

This research aimed to build on the great wealth of knowledge on student-teacher relationships, social competence, and peer outcomes while utilizing a different approach integrating race and gender. The view of intersectionality may influence those who join in reading this research to consider race coupled with student gender as a strong influence affecting the formation of a relationship as instrumental as the student-teacher relationship.

In a sample of 10,886 (8489 White, 2397 Black) students from third to fifth grade, the research completed three aims: characterizing the relationship between teacher rated closeness and conflict and students’ social outcomes in fourth and …

Reintegrating Biology Through The Nexus Of Energy, Information, And Matter, Kim L. Hoke, Sara L. Zimmer, Adam B. Roddy, Mary Jo Ondrechen, Craig E. Williamson, Nicole R. Buan

Department of Biochemistry: Faculty Publications

Information, energy, and matter are fundamental properties of all levels of biological organization, and life emerges from the continuous flux of matter, energy, and information. This perspective piece defines and explains each of the three pillars of this nexus. We propose that a quantitative characterization of the complex interconversions between matter, energy, and information that compose this nexus will help us derive biological insights that connect phenomena across different levels of biological organization. We articulate examples from multiple biological scales that highlight how this nexus approach leads to a more complete understanding of the biological system. Metrics of energy, information, …

Matchthem: Matching And Weighting After Multiple Imputation, Farhad Pishgar, Noah Greifer, Clémence Leyrat, Elizabeth Stuart

The R Journal

Balancing the distributions of the confounders across the exposure levels in an observational study through matching or weighting is an accepted method to control for confounding due to these variables when estimating the association between an exposure and outcome and reducing the degree of dependence on certain modeling assumptions. Despite the increasing popularity in practice, these procedures cannot be immediately applied to datasets with missing values. Multiple imputation of the missing data is a popular approach to account for missing values while preserving the number of units in the dataset and accounting for the uncertainty in the missing values. However, …

Estimating Social Influence Effects In Networks Using A Latent Space Adjusted Approach In R, Ran Xu

The R Journal

Social influence effects have been extensively studied in various empirical network research. However, many challenges remain in estimating social influence effects in networks, as influence effects are often entangled with other factors, such as homophily in the selection process and the common social-environmental factors that individuals are embedded in. Methods currently available either do not solve these problems or require stringent assumptions. Recent works by Xu (2018) and others have shown that a latent space adjusted approach based on the latent space model has the potential to disentangle the influence effects from other processes, and the simulation evidence has shown …

The Complicated Road From Academic Dismissal To Degree Completion: A Phenomenological Exploration Of The Student Experience, Annmarie Gottner

Department of Educational Administration: Dissertations, Theses, and Student Research

Graduation rates are a key metric for measuring success, both for the student who attains their degree and the higher education institution that awards the diploma. In a time of increasing social pressure to demonstrate the value of the higher education enterprise, colleges and universities have become increasingly attentive to the graduation rates for their students. Individual students are sensitive to their likelihood of degree completion as costs associated with higher education increase alongside continued perception that employability is positively impacted by a college diploma. Faculty and administrators are keenly committed to supporting students to graduation success, and the economic …

Behavior Modeling Training, Megan Paul

Umbrella Summaries

What is behavior modeling training?

Behavior modeling training (BMT) involves the following five steps: “(a) describing to trainees a set of well-defined behaviors (skills) to be learned, (b) providing a model or models displaying the effective use of those behaviors, (c) providing opportunities for trainees to practice using those behaviors, (d) providing feedback and social reinforcement to trainees following practice, and (e) taking steps to maximize the transfer of those behaviors to the job” (Taylor et al., 2005, p. 692). BMT can be used to train a variety of skills, from interpersonal skills like conflict management, interviewing, assertive communication, and …

Signaling In Training, Megan Paul

Umbrella Summaries

What is signaling?

In a learning environment, signaling refers to cues that direct learners’ attention to specific instructional content or that emphasize how the content is organized (van Gog, 2014). Signals can be verbal (oral or written) or visual (static or dynamic images or graphics). More commonly studied examples include:

signals in written materials: underlining, italics, bold, highlighting, outlines, headings, overviews, and summaries

signals in visual materials: arrows, circles, flashing, color coding, spotlighting (graying out some content), zooming in on key content, and gestures of pedagogical agents

When signals are used only in written text (i.e., without accompanying visuals), they …

The Dynamics Of Dominance: Open Questions, Challenges And Solutions, Eli D. Strauss, Daizaburo Shizuka

School of Biological Sciences: Faculty Publications

Although social hierarchies are recognized as dynamic systems, they are typically treated as static entities for practical reasons. Here, we ask what we can learn from a dynamical view of dominance, and provide a research agenda for the next decades. We identify five broad questions at the individual, dyadic and group levels, exploring the causes and consequences of individual changes in rank, the dynamics underlying dyadic dominance relationships, and the origins and impacts of social instability. Although challenges remain, we propose avenues for overcoming them. We suggest distinguishing between different types of social mobility to provide conceptual clarity about hierarchy …

Preparing To Fill The Leadership Gap: The Challenges Facing Women Leaders In Mid-Level Positions At Urban Community Colleges, Kia L. Hardy, Mitchell R. Williams, Kim Bullington, Felecia Commodore

Journal of Women in Educational Leadership

Community college presidents are currently retiring at rapid rates, and this turnover in leadership is expected to continue. As these important post-secondary institutions face the loss of senior-level leaders, women in mid-career positions are preparing to fill the gap in the leadership pipeline. Although previous studies have examined the leadership challenges faced by women leaders, the focus has been on presidents and vice presidents. This study fills a gap in the literature by examining the leadership experiences of women in mid-level positions - specifically deans and directors - and to identify their unique employment mobility challenges.

The purpose of this …

Correlated Evolution Of Distinct Signals Associated With Increased Social Selection In Female White-Shouldered Fairywrens, John Anthony Jones, Karan J. Odom, Ian R. Hoppe, Doka Nason, Serena Ketaloya, Jordan Karubian

School of Natural Resources: Faculty Publications

Conspicuous female signals have recently received substantial scientific attention, but it remains unclear if their evolution is the result of selection acting on females independently of males or if mutual selection facilitates female change. Species that express female, but not male, phenotypic variation among populations represents a useful opportunity to address this knowledge gap. White-shouldered fairywrens (Malurus alboscapulatus) are tropical songbirds with a well-resolved phylogeny where female, but not male, coloration varies allopatrically across subspecies. We explored how four distinct signaling modalities, each putatively associated with increased social selection, are expressed in two populations that vary in competitive pressure on …

Secondary Traumatic Stress (Sts) – Its Impact On The Child Welfare Workforce And Strategies For Agencies To Address It, Quality Improvement Center For Workforce Development

Other QIC-WD Products

Secondary traumatic stress (STS) can mimic symptoms of post-traumatic stress disorder (PTSD) (Bride, 2007). These symptoms include having dreams and flashbacks of the traumatic event, avoiding activities or places that might remind someone of the traumatic event, having sleep issues, being irritable, difficulty concentrating, or being hypervigilant. In this video, child welfare staff share how the trauma they experience as part of their job affects them, including physical and emotional reactions and the desire to leave the field. Unfortunately, experiencing STS is very common among the child welfare workforce. Although child welfare is not the only profession that is exposed …

An Ethnographic Interpretation Of Latino Perspectives On Family Engagement In Education, Mary Pollema

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

In this period of intense demographic change and educational reform that strongly emphasizes the imperative of family engagement, yet implicates minority culture parents as not being involved, it behooves the field of education to take a closer look at the rigidity that schools utilize in their normalized perceptions and practices of parental involvement. Effective involvement can consist of a number of different activities, but only a few are acknowledged in educational discourse. Therefore, it is important to hear the perspectives of families of other cultures in order to bring to light new understanding that will assist schools in building stronger …

Cognitive Effects Of Alcohol Use And Sleep Disruption In College Students, Taylor English

Department of Psychology: Dissertations, Theses, and Student Research

Alcohol use and sleep disruption are highly prevalent amongst college students, yet their combined effects on cognitive functioning and subsequent classroom performance have not been fully examined. Alcohol use has been shown to negatively impact cognitive functioning, especially in college students without fully matured brain regions. This has led to decreases in academic functioning and increases in college dropout. Disruptions in sleep functioning can lead to both lapses in attention and an overall decrease in attention, which can negatively impact learning in a classroom environment.

Participants were 96 undergraduate students who were invited to participate based on responses from a …

Strategies For Highlighting Items Within Visual Scene Displays To Support Augmentative And Alternative Communication Access For Those With Physical Impairments, Kevin Pitt, John W. Mccarthy

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: In contrast to the traditional grid-based display, visual scene displays (VSDs) offer a new paradigm for aided communication. For individuals who cannot select items from an AAC display by direct selection due to physical impairments, AAC access can be supported via methods such as item scanning. Item scanning sequentially highlights items on a display until the individual signals for selection. How items are highlighted or scanned for AAC access can impact performance outcomes. Further, the effectiveness of a VSD interface may be enhanced through consultation with experts in visual communication. Therefore, to support AAC access for those with physical …
