Gender Differences In Social Support, Self-Salience, And Mental Health, Ee Shin (Emily) Hum, Christina Falci

UCARE: Research Products

Men and women tend to manifest distinct mental health outcomes. Specifically, women report higher levels of internalizing symptoms, such as depression and anxiety, whereas men report higher levels externalizing symptoms, such as alcohol abuse (Rosenfield, S., Lennon, M. C., & White, H. R., 2005; Rosenfield, S., & Smith, D., 2010). However, it is unclear what mechanisms shape the gender differences in mental health outcomes. This research will explore two key possible mechanisms: social support and self-salience. Our aims in this study are to examine how and why mental health outcomes vary by gender? And also to what extent do social …

Perceptions Of Well-Being In Nonmetropolitan Nebraska: 2016 Nebraska Rural Poll Results, Rebecca Vogt, Cheryl Burkhart-Kriesel, Randolph Cantrell, Brad Lubben, Larry J. Mcelravy Jr.

Publications from the Center for Applied Rural Innovation (CARI)

Certain indicators have pointed to overall economic growth in Nebraska. The state’s unemployment rate has remained among the lowest in the nation and wages have increased. However, net farm income continued to decline last year and employment growth in the state has been largely concentrated in the metropolitan counties. Given the challenges and uncertainties of recent years, how do rural Nebraskans believe they are doing and how do they view their future? How satisfied are they with various items that influence their well-being? Have these views changed over the past 21 years? This paper provides a detailed analysis of these …

Global/Local Processing In Incidental Perception Of Hierarchical Structure, Mark S. Mills

Department of Psychology: Dissertations, Theses, and Student Research

The goal of the current thesis is to provide a framework for investigating and understanding visual processing of hierarchical structure (i.e., local parts nested in global wholes, such as trees nested in forests) under incidental processing conditions—that is, where processing of information at global and local levels is both uninformative (cannot aid task performance) and task-irrelevant (need not be processed to perform the task). To do so, a novel method combining two widely-used paradigms (spatial cueing and compound stimulus paradigms) is used for implicitly probing observers’ perceptual representations over the course of processing. This compound arrow cueing paradigm was used …

Family Communication About Sex: A Qualitative Analysis Of Gay And Lesbian Parents' Parent–Child Sex Communication, Allison Bonander

Department of Communication Studies: Dissertations, Theses, and Student Research

As the number of same-sex parents creating families and raising children rises, the stigma surrounding parent-child sex communication (PCSC) remains constant. Parents serve as one of the primary sources of information regarding sex and sexuality to their children; however, gay and lesbian parent-child sex communication remains largely unstudied. Framed within grounded theory, the primary goal of this study is to investigate how gay and lesbian parents navigate and enact parent-child sex communication with their children. Through 22 in-depth interviews with gay and lesbian parents who have directly communicated about sex and sexuality with their children, the following four research questions …

Infant Language Assessment Predicts Later Math Disabilities, Aaron T. Halvorsen, Dennis Molfese

UCARE: Research Products

Prevention of cognitive disabilities currently remains out of reach. Yet, interventions are crucial to maximizing developmental outcomes later in life. To be effective, interventions must occur at the earliest age possible to mitigate potential developmental problems. This study is an attempt to identify newborn infants at risk for developing math disabilities later in life. Several studies used assessment tests at relatively late ages in order to predict future cognitive abilities (Aarnoudse-Moens et al., 2013; Kiechl-Kohlendorfer et al., 2013). More recent research used MRI scans of neonate brains to investigate the relationships between academic abilities and preterm births (Ullman et al., …

An Extendable Visualization And User Interface Design For Time-Varying Multivariate Geoscience Data, Yanfu Zhou

School of Computing: Dissertations, Theses, and Student Research

Geoscience data has unique and complex data structures, and its visualization has been challenging due to a lack of effective data models and visual representations to tackle the heterogeneity of geoscience data. In today’s big data era, the needs of visualizing geoscience data become urgent, especially driven by its potential value to human societies, such as environmental disaster prediction, urban growth simulation, and so on. In this thesis, I created a novel geoscience data visualization framework and applied interface automata theory to geoscience data visualization tasks. The framework can support heterogeneous geoscience data and facilitate data operations. The interface automata …

Behavioral Effects Of Phencyclidine On Nicotine Self- Administration And Reinstatement In The Presence Or Absence Of A Visual Stimulus In Rats, Natashia Swalve, Steven T. Pittenger, Rick A. Bevins, Ming Li

Department of Psychology: Faculty Publications

Rationale—Tobacco use is a serious health problem in the United States and this problem is potentiated in patients with schizophrenia. The reward system is implicated in schizophrenia and may contribute to the high comorbidity between nicotine use and schizophrenia but very little research has been done on the topic. The reward-enhancement effect of nicotine has been shown to be important in nicotine use, but there have been no studies on this effect in animal models of schizophrenia.

Objectives—This study was designed to determine the effects of phencyclidine, used to model negative symptoms of schizophrenia, on self-administration of nicotine with or …

The Influence Of Projection Bias On Outcomes Of Healthcare Financial Incentive Programs, Jordyn M. Bader

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This thesis contributes to the behavioral health literature and literature regarding healthcare financial incentive programs by discussing the influences of the behavioral economic concept of projection bias on programs designed to recruit healthcare providers to rural or under served areas. First, I propose an adaptation to the model of projection bias by introducing a term that captures variability in individuals’ propensity to exhibit projection bias based on the amount of effort expended in predicting future preferences. Next, I conduct a probit model regression to observe what incentive program design features and participant characteristics are likely to influence the probability of …

The Association Of Southeast Asian Nations Agricultural Total Factor Productivity, 1961–2011, Lee Kottmeyer

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This article estimates agricultural total factor productivity (TFP) growth in eight Southeast Asian nations over the time period of 1961-2011, using panel data. This study is concerned with investigating whether the recent slowdown in agricultural productivity growth exhibited by affluent societies extends to this region. Three approaches for measuring agricultural total factor productivity growth are used. First, a non-parametric Simple TFP, output, and input index is calculated. Second, a non-parametric nonstochastic Malmquist index is calculated using data envelopment analysis techniques. Finally, an econometric true fixed effects stochastic frontier model is estimated using a maximum likelihood procedure. Aggregate measures of TFP …

Are Military Regimes Really Belligerent?, Nam Kyu Kim

Department of Political Science: Faculty Publications

Does military rule make a state more belligerent internationally? Several studies have recently established that military autocracies are more likely than civilian autocracies to deploy and use military force in pursuit of foreign policy objectives. I argue that military regimes are more likely to resort to military force because they are located in more hostile security environments, and not because they are inherently aggressive. First, I show that rule by military institution is more likely to emerge and exist in states facing external territorial threats. Second, by examining the relationship between military autocracies and conflict initiation, I find that once …

Cryptosporidium Parvum Among Coprolites From La Cueva De Los Muertos Chiquitos (600–800 Ce), Rio Zape Valley, Durango, Mexico, Johnica J. Morrow, Karl Reinhard

Karl Reinhard Publications

In the present study, 90 coprolites from La Cueva de los Muertos Chiquitos (CMC) were subjected to enzyme-linked immunosorbent assay (ELISA) tests for 3 diarrhea-inducing protozoan parasites, Entamoeba histolytica, Giardia duodenalis, and Cryptosporidium parvum, to determine whether these parasites were present among the people who utilized this cave 1,200–1,400 yr ago. These people, the Loma San Gabriel, developed as a culture out of the Archaic Los Caracoles population and lived throughout much of present-day Durango and Zacatecas in Mexico. The Loma San Gabriel persisted through a mixed subsistence strategy of hunting-gathering and agricultural production. The results of …

Tiers 1, 2 & 3 Intervention: Pyramid Model For Early Childhood Education, Allison Heifner, Jan Thelan, Christine Marvin, Emily A. Dorsey, Teresa Berube, Ana Damme, Reece L. Peterson

Department of Special Education and Communication Disorders: Faculty Publications

Conclusion

The Pyramid Model represents a comprehensive effort to provide teachers, caregivers, and families the tools and strategies needed to promote and support positive behavior, prevent challenging behavior, and address the social needs of all young children. The Pyramid Model emphasizes data-based decision making, employs evidence based prevention and intervention practices, and matches the intensity of behavior intervention to the intensity level of behavior for those children in need of individual support. The Pyramid Model provides a program- wide approach for use by early childhood teachers, caregivers, and families to support the social-emotional development of young children and decrease or …

Native Advertising: An International Perspective, Emily Giller

College of Journalism and Mass Communications: Professional Projects

Native advertising is a different approach to advertising that welcomes content-based marketing. According to the Interactive Advertising Bureau (IAB), native advertising is defined as “paid for content that is relevant to the consumer experience, and is integrated into the surrounding content and is not interruptive”. Native advertising is advertising disguised as regular news content. Specific examples of native advertising include: sponsored posts, Search Engine Marketing (SEM), print stories that appear in newspapers or magazines but are promoted by a brand, and promoted posts on social media. The point of native advertising is to straddle the line between advertising and editorial …

Common Platforms And Devices Used To Access News About Native Americans, Rebekka J. Schlichting

College of Journalism and Mass Communications: Professional Projects

The opening story about Ictinike and the buzzard is a traditional oral story from my Ioway Tribe culture. It represents the way in which Native American people historically shared information and stories. Today, Native stories are shared in multiple ways: oral, written, video, audio, websites, social media, etc. This research explored the ways in which Native Americans receive their stories today, specifically news stories about Native Americans. This research was done in order to see how news outlets could better serve Native populations in the U.S. In addition, I looked at which platforms and devices are most effective for Natives …

Place-Based Learning: Instilling A Sense Of Wonder., Jeanne L. Surface

Rural Futures Institute: Publications

Place-based learning is powerful. It can be implemented in rural, suburban and urban school districts as well as universities. Contextualizing learning with the students lived experiences will increase student achievement and in the words of Rachel Carson, create “a sense of wonder so indestructible that it would last throughout life (2011).”

Nebraska's Wedding Crasher, Jennine Capó Crucet

Department of English: Faculty Publications

My building thinks of itself as Lincoln's premier wedding venue. I was not told this when I signed the lease. A glitch of duct work sends the sounds of every single party straight through the exhaust fan of my apartment's bathroom, so loud and clear that I can hear the names of everyone in the wedding party as they are announced -- not just in the bathroom, but from the living room. I can hear when people are clapping, can hear the claps as individual sonic events: I can almost always make out the crisp echo of the last person …

How Open Science Helps Researchers Succeed, Erin Mckiernan, Philip E. Bourne, C. Titus Brown, Stuart Buck, Amye Kenall, Jennifer Lin, Damon Mcdougall, Brian A. Nosek, Karthik Ram, Courtney K. Soderberg, Jeffrey R. Spies, Kaitlin Thaney, Andrew Updegrove, Kara H. Woo, Tal Yarkoni

Copyright, Fair Use, Scholarly Communication, etc.

Open access, open data, open source, and other open scholarship practices are growing in popularity and necessity. However, widespread adoption of these practices has not yet been achieved. One reason is that researchers are uncertain about how sharing their work will affect their careers. We review literature demonstrating that open research is associated with increases in citations, media attention, potential collaborators, job opportunities, and funding opportunities. These findings are evidence that open research practices bring significant benefits to researchers relative to more traditional closed practices.

“Great Job Cleaning Your Plate Today!” Determinants Of Child-Care Providers’ Use Of Controlling Feeding Practices: An Exploratory Examination, Dipti A. Dev, Brent A. Mcbride, Katherine E. Speirs, Kimberly A. Blitch, Natalie A. Williams

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

Background National early childhood obesity prevention policies recommend that child-care providers avoid controlling feeding practices (CFP) (e.g., pressure-to-eat, food as reward, and praising children for cleaning their plates) with children to prevent unhealthy child eating behaviors and childhood obesity. However, evidence suggests that providers frequently use CFP during mealtimes.

Objective Using the Academy of Nutrition and Dietetics (2011) benchmarks for nutrition in child care as a framework, researchers assessed child-care providers’ perspectives regarding their use of mealtime CFP with young children (aged 2 to 5 years).

Design Using a qualitative design, individual, face-to-face, semi-structured interviews were conducted with providers until …

Differing Perspectives On Older Adult Caregiving, Eve M. Brank, Lindsey E. Wylie

Department of Psychology: Faculty Publications

Informal older adult caregiving allows older adults to stay in their homes or live with loved ones, but decisions surrounding older adult care are fraught with complexities. Related research and case law suggest that an older adult’s need for and refusal of help are important considerations; the current study is the first to examine these factors experimentally. Two samples (potential caregivers and care recipients) provided responses regarding anticipated emotions, caregiver abilities, and allocation of daily caregiving decision making based on a vignette portraying an older adult who had a high or low level of autonomy and who accepted or refused …

Uninvolved Maternal Feeding Style Moderates The Association Of Emotional Overeating To Preschoolers’ Body Mass Index Z-Scores, Maren Hankey, Natalie A. Williams, Dipti A. Dev

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

Objective: To examine the relation between preschoolers' eating behaviors and body mass index (BMI) z-scores (BMIz) and the moderating role of permissive parent feeding styles in these associations.

Design: Cross-sectional study involving mothers' report of food-related parenting styles and child eating behaviors.

Setting: Small city in southern Mississippi.

Participants: Mother–preschooler dyads (n = 104).

Institutional Strategies For Open Educational Resources (Oers): Report Of A Cni Executive Roundtable Held April 3 & 4, 2016, Coalition For Networked Information

Copyright, Fair Use, Scholarly Communication, etc.

At the Spring 2016 CNI Membership Meeting in San Antonio, Texas, we held an Executive Roundtable on the topic of Institutional Strategies for Open Educational Resources (OERs). While this is clearly a topic of growing interest in higher education institutions, we did not anticipate the overwhelming response by CNI member institutions seeking to attend this roundtable. To meet the demand, we offered two sessions of the roundtable (with different institutions participating in each) on Sunday, April 3, and Monday, April 4. We were fortunate to have a student OER advocate from one of our participating institutions join one of the …

"A Mother For All The People": Feminist Science And Chacoan Archaeology, Carrie C. Heitman

Department of Anthropology: Faculty Publications

In 1997, Alison Wylie outlined an epistemic and ontological critique of archaeological inquiry to advance feminist science studies. Wylie’s work, I argue, remains relevant and potentially transformative for analysis of the cultural florescence that took place in Chaco Canyon, New Mexico during the ninth through twelfth centuries A.D. Archival, archaeological, and ethnographic data presented here suggest that women had important and undertheorized roles to play in the social transformations that defined emergent Chacoan society. Legacy data made available through the Chaco Research Archive provide evidence in support of Lamphere’s (2000) ritual power model interpretation of the Chacoan florescence. The advent …

The Influence Of Training On Guides And Their Environmentally Responsible Behaviors And Transformational Leadership Abilities, Nancy Qwynne Lackey

School of Natural Resources: Dissertations, Theses, and Student Research

The ecotourism and interpretive fields were established, in part, to protect natural environments. This goal is achieved by implementing environmentally responsible practices and by providing transformative experiences for visitors. Previous research suggests that ecotour and interpretive guides play a vital role in implementing environmentally responsible behaviors (ERBs) and creating transformative visitor experiences. Other researchers have found that guide training yields many benefits for guides and their abilities, but few have explored the influence of training on guides in detail. The purpose of this research was to explore the influence of established training programs on guides and their ERBs and transformational …

Pregnancy And Intimate Partner Violence In Canada: A Comparison Of Victims Who Were And Were Not Abused During Pregnancy, Tamara L. Taillieu, Douglas A. Brownridge, Kimberly A. Tyler, Ko Ling Chan, Agnes Tiwari, Susy C. Santos

Department of Sociology: Faculty Publications

The purpose of this study was to examine risk factors, indicators of severity, and differences in post-violence health effects for victims who experienced intimate partner violence (IPV) during pregnancy compared to victims who experienced IPV outside the pregnancy period. Data were from Statistics Canada’s 2009 General Social Survey. Among IPV victims, 10.5% experienced physical and/or sexual violence during pregnancy. Victims who had experienced violence during pregnancy were more likely than victims who were not abused during pregnancy to experience both less severe and more severe forms of violence. In fully adjusted models, younger age, separated or divorced marital status, as …

The Potential Water Saved When Usa Households Pay A Water Bill, Wenfeng Li

Department of Agricultural Economics: Dissertations, Theses, and Student Research

A continuing problem for both American agriculture and our society is the shortage of usage water. This problem has become more acute as our population grows and as global warming and the demands of agriculture pushes government agencies to look for ways to save water. More efficient devices are now required and households have been asked to voluntarily restrict water usage. Although less wasteful irrigation methods have been introduced, the problem of inadequate water for agriculture has continued to grow.

Interestingly, there is one area where millions of gallons of clean water are potentially wasted each year that has been …
