The Personal And The Political: Forgiveness And Reconciliation In Restorative Justice, Ari Kohen
The Personal And The Political: Forgiveness And Reconciliation In Restorative Justice, Ari Kohen
Department of Political Science: Faculty Publications
At the center of this paper are three questions: in the absence of a religious worldview, can one gain access to the concepts of forgiveness and reconciliation, can reconciliation be achieved in the absence of forgiveness or does the former depend in some way upon the latter, and can we make sense of a restorative approach to justice in the absence of either forgiveness or reconciliation? To answer these questions, I look closely at the concept of forgiveness in the first section of this article with the goals of disentangling it from its religious undertones and emphasizing its importance to …
American Revolution, Ari Kohen, Sara W. Lunsford
American Revolution, Ari Kohen, Sara W. Lunsford
Department of Political Science: Faculty Publications
When thinking about the American Revolution, one is soon confronted by the puzzle of precisely which revolution is up for discussion. As many scholars of American political thought have noted, one can make a strong case for two revolutionary moments in the founding days of the American republic: the declared separation from Britain in 1776 and the 1789 constitutional revolution. While both of these distinctive moments profoundly influenced the way people think about rights, this essay will focus on the initial revolutionary statement, the American Declaration of Independence. Doing so will enable us to examine closely both the immediate and …

Maintaining Credibility And Authority As An Instructor Of Color In Diversity-Education Classrooms: A Qualitative Inquiry, Gary Perry, Helen A. Moore, Crystal Edwards, Katherine Acosta, Connie Frey
Department of Sociology: Faculty Publications
The movement for multicultural or diversity-centered education has resulted in changes to the academic demography of the United States (Banks, 1991; Butler & Walter, 1991; Goodstein, 1994; Morey & Kitano, 1997). Institutions of higher education have integrated the voices, knowledge, and lived experiences of various underrepresented cultures and excluded groups into their formal academic curriculum. A recent survey by the American Association of Colleges and Universities (AACU) shows that 63% of colleges and universities report that they have in place, or are in the process of developing, a diversity education component in their undergraduate curriculum (AACU, 2003). Of those that …
Coping Styles And Sex Differences In Depressive Symptoms And Delinquent Behavior, Lisa A. Kort-Butler
Coping Styles And Sex Differences In Depressive Symptoms And Delinquent Behavior, Lisa A. Kort-Butler
Department of Sociology: Faculty Publications
Building on research that links gender to differences in well-being and differences in stress exposure and vulnerability, the current study examines how coping styles are gendered in ways that may contribute to sex differences in depressive symptoms and delinquent behavior. The study disaggregates stress measures to reflect gender differences in the experience of stress, examining whether avoidant, approach, and action coping condition the relationship between stress and well-being. Regression analyses were conducted using data from the National Longitudinal Study of Adolescent Health. Results revealed sex differences and similarities. The interaction of avoidant coping and stress helped explain why girls had …
Depressed Affect And Historical Loss Among North American Indigenous Adolescents, Les B. Whitbeck, Melissa L. Walls, Kurt D. Johnson, Allan D. Morrisseau, Cindy M. Mcdougall
Depressed Affect And Historical Loss Among North American Indigenous Adolescents, Les B. Whitbeck, Melissa L. Walls, Kurt D. Johnson, Allan D. Morrisseau, Cindy M. Mcdougall
Department of Sociology: Faculty Publications
This study reports on the prevalence and correlates of perceived historical loss among 459 North American Indigenous adolescents aged 11–13 years from the northern Midwest of the United States and central Canada. The adolescents reported daily or more thoughts of historical loss at rates similar to their female caretakers. Confirmatory factor analysis indicated that our measure of perceived historical loss and the Center for Epidemiologic Studies Depression scale were separate but related constructs. Regression analysis indicated that, even when controlling for family factors, perceived discrimination, and proximal negative life events, perceived historical loss had independent effects on adolescent’s depressive symptoms. …
Patriarchy, Michael R. Hill
Patriarchy, Michael R. Hill
Department of Sociology: Faculty Publications
The term patiarchy refers to an organization, institution, or society in which power, social control, material wealth, and high social status accrue predominantly to males rather than females. Patriarchy is one of the most enduring and pervasive of all social patterns. It appears in all eras, among all races, social institutions, and economic classes, and in virtually every known culture. Rising initially in early family and kinship structures, hierarchical patriarchal patterns are found today around the globe not only in family and kinship groups but also throughout the major social institutions, including language, family, economy, polity, religion, law, education, science, …
Annie Marion Maclean, Feminist Pragmatist And Methodologist, Mary Jo Deegan, Michael R. Hill, Susan L. Wortmann
Annie Marion Maclean, Feminist Pragmatist And Methodologist, Mary Jo Deegan, Michael R. Hill, Susan L. Wortmann
Department of Sociology: Faculty Publications
Annie Marion Maclean was a major Chicago sociologist and methodologist. She was profoundly influenced by the gendered division of labor in sociology during her era. Maclean combined her work with the men and women of the early Chicago school of sociology and the women of Hull-House, an early social settlement. As a feminist pragmatist, Maclean was both a theorist and practitioner who used qualitative and quantitative methods. She set precedents in the Chicago school of ethnography, participant observation, and critical methodology. Maclean, however, was not the “mother” of ethnography. Harriet Martineau holds a far stronger claim to be a founding …

Risk Factors For Trading Sex Among Homeless Young Adults, Kimberly A. Tyler
Risk Factors For Trading Sex Among Homeless Young Adults, Kimberly A. Tyler
Department of Sociology: Faculty Publications
Although numerous homeless youth report trading sex, few studies have examined risk factors associated with trading sex and even fewer have employed multivariate analyses to examine this relationship, even though trading sex is associated with many negative health outcomes. Based on a sample of 151 homeless young adults in the midwestern United States, logistic regression analyses revealed that for each additional year of age, youth were 37% more likely to have traded sex (AOR = 1.37; 95% CI = .99–1.90). White youth were 84% less likely to have traded sex than nonwhite youth (AOR = .16; 95% CI = .03–.77). …

Odds Of Having A Regular Physician And Perceptions Of Care: Ethnic Patterns For Women Ages 25–45, Karina Shreffler, Julia Mcquillan, Arthur Greil, Naomi Lacy, Christine Ngaruiya
Department of Sociology: Faculty Publications
Background and Objectives: This study’s purpose was to simultaneously investigate demographic, socioeconomic status, health status, and access-to-care factors to see if they could explain racial/ethnic differences in the odds of reproductive-aged women having a regular physician and perceptions of those women about their care. Methods: Data come from a nationally representative sample of 4,520 women ages 25–45. We used logistic regression models to ascertain the odds of having a regular doctor and feeling cared for among black, Hispanic, and Asian women as compared to non-Hispanic white women. Models contained controls for factors found significant in prior research and interaction terms. …
The Expansion Of Class Concepts And The Colorado Coal Field War Project, David M. Amrine
The Expansion Of Class Concepts And The Colorado Coal Field War Project, David M. Amrine
Nebraska Anthropologist
The Colorado Coal Field War Project was an attempt by McGuire, Reckner, and others to develop a 'working-class' archaeology that served the public as well as the archaeologists performing excavations and research. The attempt was successful, promoting and supporting ideas that had been discussed in archaeology about gender, class, and the treatment of archaeology as a craft. Their example of using archaeology to benefit communities as well as academic interests can and should be tested in other regions of the United States as well as the rest of the world.
How Effective Leaders Learn From Life: A Grounded Theory Study Of The Impact Of Significant Life Experiences Upon Leadership Development, Ryan P. Meers
Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research
Fifteen effective leaders from diverse organizational backgrounds described their significant life experiences and the impact upon their development as leaders. Using grounded theory methodology, a theoretical model emerged for assisting leaders absorb greater learning from their various life experiences. Related to the central phenomenon of how effective leaders learn from significant life experiences, four causal conditions of types of experiences were identified as influencing how leaders learn: (1) experiences of adversity or loss; (2) experiences of “stretch assignments”; (3) inspirational experiences; and (4) experiences with conflict. Strategies used by the leaders to absorb learning from their significant experiences were active …

Department of Child, Youth, and Family Studies: Faculty Publications
To advance the field of children’s services, implementation and generalization studies are needed to help us reveal the inner workings of intervention projects and how they do (or do not) achieve their outcomes. This paper provides a case study of Head Start teachers’ uptake of the Getting Ready school readiness intervention, intended to strengthen professionals’ capacity to support parental engagement in young children’s development and learning. The qualitative method of document review was used in scrutinizing home visit reports and classroom newsletters as a source of authentic evidence about teachers’ implementation and generalization of an early intervention model. Home visits …
Relation Of Caregiver Alcohol Use To Unintentional Childhood Injury, Amy Damashek, Natalie A. Williams, Kenneth Sher, Lizette Petterson
Relation Of Caregiver Alcohol Use To Unintentional Childhood Injury, Amy Damashek, Natalie A. Williams, Kenneth Sher, Lizette Petterson
Department of Child, Youth, and Family Studies: Faculty Publications
Objective The present study used a case-crossover design to investigate the association of caregiver alcohol consumption and supervision to children's injury occurrence and severity.
Method A community sample of 170 mothers of toddlers was interviewed biweekly about their children's daily injuries for a period of 6 months.
Results Proximal caregiver-reported alcohol use predicted higher likelihood of injury occurrence and higher injury severity, whereas caregiver-reported supervision predicted lower likelihood of injury occurrence and lower injury severity.
Conclusion Even at low levels, proximal caregiver alcohol use may contribute to higher risk for childhood injuries and more severe injuries. The combined effect of …

American Indians And The United States Patent And Trademark Office: The Native American Tribal Insignia Database, Charles D. Bernholz, Linda G. Novotny, Ana L. Gomez
University of Nebraska-Lincoln Libraries: Faculty Publications
The tribal insignia of American Indians offer a distinctive view into the history of these people. Recently, as the result of federal legislation, some of these materials have been brought together, for tribes that are either federally or State recognized entities, as part of the database collection maintained by the United States Patent and Trademark Office (USPTO). This article focuses on the history and use of such images; the policy response by the USPTO to the charge by the Trademark Law Treaty Implementation Act (1998) to examine the USPTO’s specific responsibility to protect such official insignia; and the Office’s resulting …
Digital Editions: Scholarly Tradition In An Avant-Garde Medium, Andrew Jewell
Digital Editions: Scholarly Tradition In An Avant-Garde Medium, Andrew Jewell
University of Nebraska-Lincoln Libraries: Faculty Publications
In our current professional environment, there is a lot of energy and attention paid to the digital humanities and the dreamy new world it is ushering in, and it is becoming increasingly difficult to finance and publish large, sophisticated scholarly editions in print. Funding agencies are now demanding that editions be published in digital format, and the success of certain editorial projects in drawing in funds and attention--Ken Price's Walt Whitman Archive, for example--suggests that future developments in the field will likely require sophisticated engagement with computers.

University of Nebraska-Lincoln Libraries: Faculty Publications
Review of The Nature of Difference: Sciences of Race in the United States from Jefferson to Genomics, edited by Evelynn M. Hammonds and Rebecca M. Herzig.
The Nature of Difference is a timely addition to conversations about race and genomics, organized so as to allow readers to make new connections between contemporary discourses and the histories of science and race. The text’s selections and the organization of the selections with introductory material are especially helpful, serving as navigational aids to the sometimes astounding statements of racial fact that could otherwise be conversation stoppers. The book would be useful either as …

Family Legacies: Constructing Individual And Family Identity Through Intergenerational Storytelling, Blair Thompson, Jody Koenig Kellas, Jordan Soliz, Jason Thompson, Amber Epp, Paul Schrodt
Family Legacies: Constructing Individual And Family Identity Through Intergenerational Storytelling, Blair Thompson, Jody Koenig Kellas, Jordan Soliz, Jason Thompson, Amber Epp, Paul Schrodt
Department of Communication Studies: Faculty Publications
The current study focused on discovering the ways in which the intergenerational transmission of family legacy stories both enables and constrains individual family members’ sense of their own identities. Using semistructured interviews, 17 third-generation family members identified a multitude of both positive and negative family legacies. Both positive and negative legacies were influenced by the storytelling context. Positive legacies portrayed families as hardworking, caring, and cohesive while negative legacies were more idiosyncratic. Individual family members typically responded to their family legacies by embracing the positive and rejecting the negative. However, individuals’ responses also pointed to additional complexities in accepting or …
Communicative And Relational Dimensions Of Shared Family Identity And Relational Intentions In Mother-In-Law/Daughter-In-Law Relationships: Developing A Conceptual Model For Mother-In-Law/Daughter-In-Law Research, Christine Rittenour, Jordan Soliz
Communicative And Relational Dimensions Of Shared Family Identity And Relational Intentions In Mother-In-Law/Daughter-In-Law Relationships: Developing A Conceptual Model For Mother-In-Law/Daughter-In-Law Research, Christine Rittenour, Jordan Soliz
Department of Communication Studies: Faculty Publications
From the perspective of daughters-in-law (N = 190), this study examined communicative and relational factors associated with positive and negative mother-in-law/daughter-in-law relationships. A structural model tested perceptions of shared family identity as a mediator between communicative factors (supportive communication, nonaccommodation, self-disclosure), family-of-origin factors, and daughter-in-law intentions regarding caregiving and future contact with the mother-in-law. Further, open-ended responses were content analyzed to identify additional relational aspects associated with satisfying mother-in-law relationships. Results from both analyses were integrated into a conceptual model to guide future research on this relationship.
The Elasticity Of Taxable Income: Influences On Economic Efficiency And Tax Revenues, And Implications For Tax Policy, Seth H. Giertz
The Elasticity Of Taxable Income: Influences On Economic Efficiency And Tax Revenues, And Implications For Tax Policy, Seth H. Giertz
Department of Economics: Faculty Publications
While research into the elasticity of taxable income (ETr), which measures the responsiveness of reported taxable income to changes in tax rates, dates back to at least Lindsey (1987), recognition of its importance as a central parameter for tax policy design did not begin to take hold until the second half of the 1990s. In fact, a 1998 survey to determine public and labor economists' views on key policy parameters (Fuchs, Krueger, and Poterba 1998) included no questions on the ETI. I suspect that a 2008 survey would include such questions, just as I suspect that a 1998 conference entitled …
A Response To Seth H. Giertz, Daniel Feenberg
A Response To Seth H. Giertz, Daniel Feenberg
Department of Economics: Faculty Publications
There are two aspects of Seth Giertz's excellent chapter that I want to talk about. One is slightly technical; I want to try to provide some explanation for why estimating elasticity of taxable income (ETI) is so difficult. I think this difficulty is unappreciated by nonspecialists, who are quick to latch onto a favorite estimate without understanding the weaknesses in the estimation. The other aspect is a bit more philosophical and addresses the different functions of the partial equilibrium analysis done here and the general equilibrium work done a few years back in the macro group at the Congressional Budget …
Unauthorized Immigration, Örn B. Bodvarsson, Hendrik F. Van Den Berg
Unauthorized Immigration, Örn B. Bodvarsson, Hendrik F. Van Den Berg
Department of Economics: Faculty Publications
One of the results of the clash between immigration policies and economic incentives is unauthorized immigration. There is no accurate data on unauthorized immigration, but estimates permit some empirical work. The motives for immigrants to enter the destination country without formal authorization are the same as those that lead immigrants to seek legal entry, and the static labor market model of immigration can be used to explain the flows of unauthorized immigrants. There are additional factors to consider, however. Unauthorized immigrants do not normally enjoy the same civil rights as legal immigrants, so the potential rewards from immigrating are …
Predatory Senescence In Ageing Wolves, Daniel R. Macnulty, Douglas W. Smith, John A. Vucetich, L. David Mech, Craig Packer
Predatory Senescence In Ageing Wolves, Daniel R. Macnulty, Douglas W. Smith, John A. Vucetich, L. David Mech, Craig Packer
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
It is well established that ageing handicaps the ability of prey to escape predators, yet surprisingly little is known about how ageing affects the ability of predators to catch prey. Research into long-lived predators has assumed that adults have uniform impacts on prey regardless of age. Here we use longitudinal data from repeated observations of individually-known wolves (Canis lupus) hunting elk (Cervus elaphus) in Yellowstone National Park to demonstrate that adult predatory performance declines with age and that an increasing ratio of senescent individuals in the wolf population depresses the rate of prey offtake. Because this ratio fluctuates independently of …
Problems With The Claim Of Ecotype And Taxon Status Of The Wolf In The Great Lakes Region, Matthew A. Cronin, L. David Mech
Problems With The Claim Of Ecotype And Taxon Status Of The Wolf In The Great Lakes Region, Matthew A. Cronin, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Koblmuller et al. (2009) analyzed molecular genetic data of the wolf in the Great Lakes (GL) region of the USA and concluded that the animal was a unique ecotype of grey wolf and that genetic data supported the population as a discrete wolf taxon. However, some of the literature that the researchers used to support their position actually did not, and additional confusion arises from indefinite use of terminology. Herein, we discuss the problems with designation of a wolf population as a taxon or ecotype without proper definition and assessment of criteria.
Koblmuller et al. (2009) wrote ‘The GL …

A Serological Survey Of Infectious Disease In Yellowstone National Park’S Canid Community, Emily S. Almberg, L. David Mech, Douglas W. Smith, Jennifer W. Sheldon, Robert L. Crabtree
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Background: Gray wolves (Canis lupus) were reintroduced into Yellowstone National Park (YNP) after a .70 year absence, and as part of recovery efforts, the population has been closely monitored. In 1999 and 2005, pup survival was significantly reduced, suggestive of disease outbreaks.
Methodology/Principal Findings: We analyzed sympatric wolf, coyote (Canis latrans), and red fox (Vulpes vulpes) serologic data from YNP, spanning 1991–2007, to identify long-term patterns of pathogen exposure, identify associated risk factors, and examine evidence for disease-induced mortality among wolves for which there were survival data. We found high, constant exposure to canine …
Feeding Ecology Of Arctic-Nesting Sandpipers During Spring Migration Through The Prairie Pothole Region, Jan Eldridge, Gary Krapu, Douglas Johnson
Feeding Ecology Of Arctic-Nesting Sandpipers During Spring Migration Through The Prairie Pothole Region, Jan Eldridge, Gary Krapu, Douglas Johnson
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
We evaluated food habits of 4 species of spring-migrant calidrid sandpipers in the Prairie Pothole Region (PPR) of North Dakota. Sandpipers foraged in several wetland classes and fed primarily on aquatic dipterans, mostly larvae, and the midge family Chironomidae was the primary food eaten. Larger sandpiper species foraged in deeper water and took larger larvae than did smaller sandpipers. The diverse wetland habitats that migrant shorebirds use in the PPR suggest a landscape-level approach be applied to wetland conservation efforts. We recommend that managers use livestock grazing and other tools, where applicable, to keep shallow, freshwater wetlands from becoming choked …
Body Size And Predatory Performance In Wolves: Is Bigger Better?, Daniel R. Macnulty, Douglas W. Smith, L. David Mech, Lynn E. Eberly
Body Size And Predatory Performance In Wolves: Is Bigger Better?, Daniel R. Macnulty, Douglas W. Smith, L. David Mech, Lynn E. Eberly
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Summary
1. Large body size hinders locomotor performance in ways that may lead to trade-offs in predator foraging ability that limit the net predatory benefit of larger size. For example, size-related improvements in handling prey may come at the expense of pursuing prey and thus negate any enhancement in overall predatory performance due to increasing size.
2. This hypothesis was tested with longitudinal data from repeated observations of 94 individually known wolves (Canis lupus) hunting elk (Cervus elaphus) in Yellowstone National Park, USA. Wolf size was estimated from an individually based sex-specific growth model derived from …
