Strengths Versus Deficits: The Impact Of Gender Role Conflict And Counseling Approach On The Appeal Of Therapy For Men, Jeff Reznicek-Parrado

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

Current trends from the fields of mental health, criminal justice, and sociology suggest that despite men’s significant mental health problems (i.e. Moscick, 1995; Sue, Sue, & Sue, 2003; Greenfield & Snell, 1999; Follman, Aronsen, & Pan, 2013), they are much more reluctant to seek mental health help than women (Addis & Mahalik, 2003; Olfson & Marcus, 2010). Sociologists and psychologists have suggested that this disparity in help seeking can be largely explained by a cultural mismatch between the context of masculinity and the context of psychotherapy. Psychologists have called for a paradigm shift in the way clinical services are rendered …

Changes In Avian Vocalization Occurrence And Frequency Range During The Winter, Amy I. Oden

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

Human population expansion has led to an increase in vehicle traffic and therefore vehicle noise. Traffic and traffic noise has been shown to affect avian abundance, breeding success, density and species diversity on the landscape. Documented changes in avian vocalizations due to traffic noise include shifts in amplitude, frequency, rate, timing, and duration of vocalizations along with a number of behavioral adaptations. During the winters of 2011–2012 and 2012–2013, we recorded and measured the “chick-a-dee” vocalization of Black-capped Chickadees (Poecile atricapillus) and the “po-ta-to-chip” vocalization of American Goldfinches (Spinus tristis) to determine …

Targeted Threats: An Examination Of Thematic Content And Approach Behavior Displayed By Mentally Ill And Non-Mentally Ill Contactors, Charles D. Darrow

Department of Psychology: Dissertations, Theses, and Student Research

Threat assessment involves a set of investigative and operational techniques used to identify, assess, and manage the risks of targeted violence and other problematic approach behavior. The threat assessment approach continues to be refined through empirical research conducted in an effort to identify and better understand the risk factors for engaging in such behaviors, which accounts for the transition to a more dynamic evaluative process. Pertinent is the examination of thematic content utilized by subjects who engage in threatening behavior toward identifiable victims. In targeted threat assessment, thematic content examination involves the analyses of what the threatening individual is saying …

Military Strategy: Theory And Concepts, Randall G. Bowdish

Department of Political Science: Dissertations, Theses, and Student Research

Military strategy was long described as atheoretical—an art that could only be fully comprehended by military genius. This contention is no longer held, as military staffs, comprised of experts and specialists, are able to formulate strategy aided by mini-theories of strategy and a process that takes advantage of collective wisdom rather than singular genius. But the mini-theories of strategy remain underdeveloped and an overarching theory of military strategy does not yet exist. In this dissertation I build a grand theory of military strategy, consisting of a simple two-pole, physical and psychologically oriented framework, mini-theories of military strategy, and additionally, concepts …

The Role Of Emotion In Environmental Decision Making, Hannah Dietrich

Department of Psychology: Dissertations, Theses, and Student Research

Given the environmental concerns of our planet, it is imperative to consider issues of environmental sustainability. Researchers argue that the most serious environmental problems are not merely issues of science, but that of individual behavior. Solutions, therefore, must consider the role of the individual—how one can change his/her behaviors to be more environmentally conscious. The experience of negative or positive emotions, may impact not only people’s experiences with the environment, but also their tendency to engage in pro-environmental behavior. The present study sought to experimentally investigate the role of emotion and information on pro-environmental behavior change. Results indicate that neither …

Impacts Of The Federal Farm And Ranch Lands Protection Program: An Assessment Based On Interviews With Participating Landowners, J. Dixon Esseks, Brian J. Schilling, Alexander Hahn

Center for Great Plains Studies: Staff and Fellows Publications

Focus of the Study

From mid-February to mid-May 2012, a research team at the University of Nebraska-Lincoln surveyed 506 owners whose agricultural land was protected from development through conservation easements that were funded in part by USDA’s Farm and Ranch Lands Protection Program (FRPP). This program “provides matching funds to help purchase development rights to keep productive farm and ranchland in agricultural uses. Working through existing programs, USDA partners with State, tribal, or local governments and non-governmental organizations to acquire conservation easements or other interests in land from landowners, USDA provides up to 50 percent of the fair market easement …

The Impact Of Environmental Regulation On The Structure Of The Us Hog Industry, Gibson Nene, Azzeddine M. Azzam, Karina Schoengold

Department of Agricultural Economics: Faculty Publications

Abstract: This paper develops a comparative statics model of long-run industry equilibrium in the presence of size-based environmental regulation stringency and applies the model to the United States hog industry. The economic model shows that when size-based environmental stringency is also size-biased, large farms downsize, expand, or do neither depending on how environmental stringency shifts their marginal production cost relative to their average cost. Empirical testing using data from the top-ten hog producing states suggests that environmental regulation stringency has limited impact on small farms and leads to a reduction in the number of large farms. We cannot reject positive …

A Natural Resource Condition Assessment For Sequoia And Kings Canyon National Parks, Appendix 16 - Bats, Alice Chung-Maccoubrey

United States National Park Service: Publications

Scope of Analysis

North American bats are highly unique animals that have historically been overlooked by land managers and misunderstood by the public. Bats are unique as the only true flying mammals and due to their exceptionally long lives (5-15 years) and unusually low reproductive rates (typically one young per year) for their small size. Most North American bat species are insectivorous, serve as the primary predators of nocturnal insects, and can consume up to one-third of their weight in insects per night. Thus, bats play a role in regulating insect populations, insect-related ecological processes, and nutrient redistribution and cycling …

Homeless Youths’ Hiv Risk Behaviors With Strangers: Investigating The Importance Of Social Networks, Kimberly A. Tyler

Department of Sociology: Faculty Publications

The purpose of this study was to examine the relationship between homeless youths’ HIV risk behaviors with strangers and risk and protective characteristics of their social networks. Data were from the Social Network and Homeless Youth Project. A total of 249 youth aged 14 to 21 years were interviewed over 15 months in three Midwestern cities in the United States using a systematic sampling strategy. Multivariate results revealed that homeless youth with a greater average number of network members who engaged in more drug risk behaviors and who pressured them into precarious behaviors at least once were more likely to …

The Role Of Drinking In New And Existing Friendships Across High School Settings*, Jacob E. Cheadle, Deadric T. Williams

Department of Sociology: Faculty Publications

We use 9 Add Health high schools with longitudinal network data to assess whether adolescent drinkers choose friends who drink, prefer friends whose friends drink, if selection differs between new and existing friendships, and between schools. Utilizing dynamic social network models that control for friend influences on individual alcohol use, the results show that drinkers do not strongly prefer friends who drink. Instead, they favor close friends whose friends’ drink, suggesting that alcohol matters for selection on the social groups and environments that friends connect each other to. The role of alcohol use differs by whether friendships are new or …

The Impact Of Camp Erin On Bereaved Youth, Alysondra Duke

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

Approximately 5% of adolescents and children will experience the significant loss of a loved one before the age of 15 (Currier, Holland, & Neimeyer, 2007). Numerous intervention efforts have been utilized to normalize the grief process for youth and to assist in the expression and exploration of loss. Several organizations have created weekend-long camps to serve as an avenue for youth to connect with others who have experienced loss with the hope that this early intervention effort may prevent youth from the onset of depression, chronic anxiety, or other psychological conditions. As well, early intervention has been noted as important …

Connecting Scientific Articles With Research Data: New Directions In Online Scholarly Publishing, Ijsbrand Jan Aalbersberg, Judson Dunham, Hylke Koers

Copyright, Fair Use, Scholarly Communication, etc.

Researchers across disciplines are increasingly utilizing electronic tools to collect, analyze, and organize data. However, when it comes to publishing their work, there are no common, well-established standards on how to make that data available to other researchers. Consequently, data are often not stored in a consistent manner, making it hard or impossible to find data sets associated with an article – even though such data might be essential to reproduce results or to perform further analysis. Data repositories can play an important role in improving this situation, offering increased visibility, domain-specific coordination, and expert knowledge on data management. As …

Three Essays On Renewable Energy, Kepifri Alpha Lakoh

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

This dissertation studies three main issues related to renewable energy in the United States and in Sub Sahara Africa.

The first chapter seeks to provide answers to a very fundamental question for second generation biofuels: “How much crop residue can farmers harvest from their fields for sale to cellulosic ethanol companies without affecting current levels of production?” The model developed is applied to 101 counties from four Midwestern states in the United States (Colorado, Iowa, Nebraska and Wyoming). Results show that soil organic matter significantly contributes to explaining changes in technical efficiency and total factor productivity. Furthermore, average crop …

Activism, Deliberation, And Networked Public Screens: Rhetorical Scenes From The Occupy Moment In Lincoln, Nebraska (Part 1 & 2), Joshua P. Ewalt, Jessy J. Ohl, Damien S. Pfister

Department of Communication Studies: Faculty Publications

Part 1 of this manuscript is a dramatization of five rhetorical scenes that take the Occupy phenomenon as a moment to explore features of contemporary social protest and change. Drawing on rhetorical field notes collected over the first two weeks of Occupy Lincoln in Nebraska, we identify how historical tensions between activism and deliberation were both complicated and reasserted as the Occupy moment became a movement. The rhetorical scenes partially replicate actual conversations, though they are remediated through three composite figures: Anda, a longtime social activist; John, an advocate of democratic deliberation; and Dajuan, an undergraduate organizer of the local …

Community Partners’ Assessment Of Service Learning In An Interpersonal And Small Group Communication Course, Sarah Steimel

Department of Communication Studies: Faculty Publications

This assessment explored community partners’ perceptions of service learning in a required communication course. Semi-structured interviews revealed that community partners believed that students were providing needed and valuable service, students were learning about the community and students were learning through their application of course skills in an applied context. However, community partners also felt that students were unaware of or did not care what they should be learning, that faculty contact was rare or nonexistent and that community feedback opportunities were rare and undervalued by faculty. Results suggest specific improvements necessary in service learning assignment design.

Climate Change Tipping Points: A Point Of No Return?, Elise Lequire

Joint Fire Science Program Digests

Summer 2012 saw records fall for intensity of drought and number, size, and cost of wildfires in the Central and Western United States, and the climate forecast calls for more of the same in the near and distant future. When wildfire breaks out, emergency responders decide their immediate strategy based on past experience and quick judgment calls. But in the long term, land managers need to plan for a warmer climate on a time scale of decades, or even a century or more, to better reflect the life span of trees and forests. Studies supported by the Joint Fire Science …

Factors Affecting Students Walking To School: Case Study Of Two Middle Schools In Lincoln, Nebraska, Nivin S. Khalil

Community and Regional Planning Program: Theses

Physical activity, including walking, can be a very healthy and sustainable mode of transportation. Children walking to their schools can get a lot of benefits from acquiring good habits that can be carried through their adulthood. Also, walking to school can reverse the trend of increasing obesity rates among children in the United States. This study is trying to identify the effect of urban form, presented in the distances between residences and schools, on the children’s behavior whether they walk to school or not depending on different urban forms around their schools. Two middle schools in Lincoln, Nebraska were selected …

Authentic, Transformational Leadership: A Phenomenological Study Of The Experiences Of Black/White Biracial Leaders, Carmen R. Zafft

Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research

This phenomenological study described the racial identity and leadership experiences of eight community, education, and business Black/White biracial leaders. Four central themes emerged relating to the participants’ racial identity choices: (a) family discourse, (b) social networks, (c) appearance, and (d) identity work. Three central themes emerged relating to the participants’ leadership experiences: (a) cultural agility: “Blessed to be flexible”, (b) perceived representation: “I look like them”, and (c) transformational leadership: “I lead so others can grow.” Because the participants were conscious of their identity development experience, all demonstrated a strong sense of self which influenced how they experienced leadership. As …

Volunteer Programming Impact On Long-Term Care Facilities, Paul P. Falkowski

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

The purpose of this present study was to examine the direct and indirect effects between the organizational structure of a long-term care facility, the amount of volunteers at the facility, the activities in which volunteers engage while at the facility and daily average number of hours care staff spend with nursing home residents. The time care staff spends with residents has been directly linked to the quality of care provided by the facility. This time is measured by calculating nursing hours per patient and it includes only nursing staff hours.The data for this study come from the National Nursing Home …

Stress, Coping, And Depression In Adolescents： A Longitudinal Analysis Of Data From National Longitudinal Study Of Adolescent Health, Xiaoyun Zhang

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

The study examined the relationships among stress, coping and depression using the public-use data from the first three waves of the National Longitudinal Study of Adolescent Health (Harris & Udry, 1994-2008). The total sample of 3844 participants aged from 11 to 27 was included in the analysis. Latent growth curve modeling was used to identify the developmental trajectories of depressive symptoms and stressful life events from age 12 to age 24, respectively; Latent growth curve modeling with two-construct parallel processes was used to examine the associations between stressful life events and depressive symptoms over time. Path analysis was used to …

Private Soldiers In Africa: A Look At The Effects Of Private Military Contractors And Mercenaries On The Duration Of Civil Wars In Africa From 1960 To 2003, Seth H. Loven

Department of Political Science: Dissertations, Theses, and Student Research

This thesis examines the effect of private soldiers, both Mercenaries and Private Military Contractors (PMC), on the duration of civil wars in Africa from 1960 to 2003. Linear regression is used to determine if private soldiers increase or decrease the duration of civil wars. Ultimately it is found they have little to no statistical impact. This is contrary to the expectations of the theoretical literature on private military contractors, some of which expects private soldiers to profit from war and seek to lengthen duration, and some of which expects the use of additional private soldiers to shorten the duration of …

Suicide Attacks In Afghanistan: Why Now?, Ghulam Farooq Mujaddidi

Department of Political Science: Dissertations, Theses, and Student Research

Why, contrary to their predecessors, did the Taliban resort to use of suicide attacks in the 2000s in Afghanistan? By drawing from terrorist innovation literature and Michael Horowitz’s adoption capacity theory—a theory of diffusion of military innovation—the author argues that suicide attacks in Afghanistan is better understood as an innovation or emulation of a new technique to retaliate in asymmetric warfare when insurgents face arms embargo, military pressure, and have direct links to external terrorist groups. The findings of my in-depth case study of Afghanistan between 1978 and 2010 support the proposition and show that it was an …

Deterring The Democratic People’S Republic Of Korea: The Role Of Japan’S Ballistic Missile Defense, Jonathan Trexel

Department of Political Science: Dissertations, Theses, and Student Research

This dissertation explores the role of Japan’s ballistic missile defense (BMD) program and its deterrent effect upon North Korean behavior. A mixed-methods approach is employed to analyze the topic. Empirical quantitative data included tabulated monthly cooperative-conflictual behavioral interaction between Japan and North Korea spanning a 22-year timeframe (1990-2011). In addition, a strategic profile developed from deterrence theory provided essential qualitative background to compliment the quantitative analysis. Japan’s BMD program was divided into four periods reflecting decision points or phases of program development. Results indicated varied BMD deterrence effectiveness, with two periods indicating Japan’s BMD program strengthened deterrence, one period indicating …

Adolescent Depressive Symptoms And Substance Use: The Mediating Influence Of Health Service Utilization, Sarah E. Malone

Department of Sociology: Dissertations, Theses, and Student Research

A large number of American adolescents suffer from depression and the consequences have been shown to be detrimental to their well-being. Adolescent substance use is also an increasing social problem due to the high usage rates and negative lifelong consequences for users. This paper explores the relationships between victimization, substance use, psychological health service utilization, and depressive symptoms in a sample of 4,757 adolescents. Using two waves of data from the National Longitudinal Study of Adolescent Health (Add Health), the results revealed a positive relationship between victimization and adolescent depressive symptoms, even after controlling for several demographic variables and previous …

Toughness Predicts Performance In College Football, Joseph B. Rigoni

Department of Psychology: Dissertations, Theses, and Student Research

A premium college football player is estimated to generate over $1 million for his program, so optimal player assessment and selection are paramount. Lean body mass, back squat, and vertical jump have been the most predictive physical test scores, but such metrics typically account for less than 10% of variance in football performance. NFL scouts have tended to rely on vertical jump, 40-yard dash, and 20-yard shuttle scores, but interestingly, reliance on none of the physical tests conducted at the NFL Combine was predictive of team success; in fact, teams that relied on fewer total physical test scores tended to …

Social Affiliation: A Model Of Anxious Avoidance In Women, Milena Stoyanova

Department of Psychology: Dissertations, Theses, and Student Research

There is substantial evidence demonstrating that women experience greater anxiety and fear compared to men. However, our understanding of specific factors accounting for women’s greater vulnerability remains rather limited. Taylor and colleagues (2000) proposed that women may have a different biobehavioral response to stress, which has evolved to protect and nurture offspring. The tend-and-befriend model provides new opportunities to explore underlying processes that may contribute to women’s greater anxiety and fear.

The present study examined women’s stress response combined with the absence of positive social contact as it relates to the presentation of fear and anxiety. One hundred and seven …
