Farm Lease Termination, J. David Aiken

Cornhusker Economics

Many farm leases, especially those between family members, are not written but are verbal "handshake" agreements. Because nothing is in writing, the parties may have different recollections of their agreement, making lease disputes more difficult to resolve. The most common legal issue associated with verbal farm leases is how a lease may legally be terminated. For unwritten leases, six months advance notice must be given to legally terminate the lease. In contrast, the termination of a written lease is determined by the terms of the written lease. If nothing is specified, a written lease terminates automatically on the last day …

Exploring The Relationships Of Perceived Discrimination, Anger, And Aggression Among North American Indigenous Adolescents, Kelley J. Sittner Hartshorn, Les B. Whitbeck, Dan R. Hoyt

Department of Sociology: Faculty Publications

A growing body of research has documented associations between discrimination, anger, and delinquency, but the exact nature of these associations remains unclear. Specifically, do aggressive behaviors emerge over time as a consequence of perceived discrimination and anger? Or do adolescents who engage in aggressive behavior perceive that they are being discriminated against and become angry? We use autoregressive cross-lagged path analysis on a sample of 692 Indigenous adolescents (mean age = 12 years) from the Northern Midwest and Canada to answer these research questions. Results showed that the direction of effects went only one way; both perceived discrimination and anger …

A Cluster Analysis Of Service Utilization And Incarceration Among Homeless Youth, Lisa A. Kort-Butler, Kimberly A. Tyler

Department of Sociology: Faculty Publications

Our paper examines service usage (e.g., shelter) as well as a typology of individuals who are most likely to use groupings of services among 249 homeless youth. Our results revealed that the majority of homeless young people have used food programs (66%) and street outreach (65%) on at least one occasion within the past year. Cluster analysis of services revealed four distinct groups: (1) basic survival service use, characterized by above average shelter, food, and outreach service use, but below average on counseling, substance abuse/ mental health services, and incarceration; (2) multiple service use, which included above average use of …

The Small-School Friendship Dynamics Of Adolescent Depressive Symptoms, Jacob E. Cheadle, Bridget J. Goosby

Department of Sociology: Faculty Publications

Adolescence is a time when depressive symptoms and friendships both intensify. The authors ask whether friendships change in response to depressive symptoms, whether individual distress is influenced by friends’ distress, and whether these processes vary by gender. To answer these questions, the authors use longitudinal Simulation Investigation for Empirical Network Analysis models to study how changes in friendships and depressive symptoms intertwine with each other among all adolescents as well as boy-only and girl-only networks in seven smaller K-12 Add Health schools. The findings indicate that distressed youth are more likely to be socially excluded, though depressive symptoms are also …

Poor Parenting And Antisocial Behavior Among Homeless Young Adults : Links To Dating Violence Perpetration And Victimization, Kimberly A. Tyler, Lisa Melander

Department of Sociology: Faculty Publications

Though research has examined risk factors associated with street victimization among homeless young people, little is known about dating violence experiences among this group. Given homeless youths’ elevated rates of child maltreatment, it is likely that they are at high risk for dating violence. As such, the current study examined the association between child maltreatment and parental warmth with dating violence perpetration and victimization through substance use and delinquency among a sample of 172 homeless males and females. Results from path analysis revealed that physical abuse, sexual abuse, and neglect were all significant correlates of both substance use and delinquency, …

An Examination Of Within-Person Variation In Response Propensity Over The Data Collection Field Period, Kristen Olson, Robert M. Groves

Department of Sociology: Faculty Publications

Statistical examinations of deterministic and stochastic response propensity assert that a sample case’s propensity is determined by fixed respondent characteristics. The perspective of this article, that of dynamic response propensities, differs, viewing sample cases’ propensities as evolving over the course of the data collection. Each sample case begins the data collection period in a “base” response propensity. Each change in the data collection protocol which the survey organization subsequently makes might change that base propensity. This article examines four questions: (1) Is there any evidence that the average response propensities of sampled individuals vary over the data collection? (2) Is …

Rotten, Vile, And Depraved! Depictions Of Criminality In Superhero Cartoons, Lisa A. Kort-Butler

Department of Sociology: Faculty Publications

The literature argues that media depictions of crime present messages that conform to and promote the dominant ideology about the causes of crime and the nature of criminality. Most research focuses on television news and adult programs, but little research examines messages about criminality present in children’s shows. To fill this gap, a content analysis of children’s cartoons was conducted, using episodes of Batman: The Animated Series, Spider-Man, and Justice League Unlimited. Three central themes emerged. First, much criminal activity centers on greed. Second, criminals are aware of right and wrong but pursue crime to meet their own self-interests. Third, …

Does Giving People Their Preferred Survey Mode Actually Increase Survey Participation Rates? An Experimental Examination, Kristen Olson, Jolene D. Smyth, Heather M. Wood

Department of Sociology: Faculty Publications

Survey research has long grappled with the concept of survey mode preference: the idea that a respondent may prefer to participate in one survey mode over another. This article experimentally examines the effect of mode preference on response, contact, and cooperation rates; mode choice; and data collection efficiency. Respondents to a 2008 telephone survey (n = 1,811; AAPOR RR3 = 38 percent) were asked their mode preference for future survey participation. These respondents were subsequently followed up in 2009 with two independent survey requests. The first follow-up survey request was another telephone survey (n = 548; AAPOR RR2 = 55.5 …

The Effects Of Item Saliency And Question Design On Measurement Error In A Self-Administered Survey, Michael J. Stern, Jolene D. Smyth, Jeanette Mendez

Department of Sociology: Faculty Publications

Recent survey design research has shown that small changes in the structure and visual layout of questions can affect respondents’ answers, but the results are not always consistent across studies. One possible reason for some of the inconsistency may be differences in the item saliency of the questions used in the experiments. In this article, the authors examine how item saliency might influence visual design effects. The authors report the results of three experimental alterations in question format and visual design using data from a 2005 random sample mail survey of 1,315 households. The results suggest that the saliency of …

Development And Application Of Methods Used To Source Prehistoric Southwestern Maize: A Review, Larry Benson

United States Geological Survey: Staff Publications

Archaeological cobs free of mineral contaminants should be used to source the soils in which they were grown. Mineral contaminants often contain much higher concentrations of metals than vegetal materials and can alter a cob’s apparent metal and heavy-isotope content. Cleaning a cob via immersion in an acid solution for more than a few minutes will result in the incongruent and sometimes complete leaching of metals, including strontium (Sr), from the cob. When using ⁸⁷Sr/⁸⁶Sr to determine the location of potential agriculture fields, it is best to either integrate several depth-integrated soil samples or to integrate several …

“If You Can Dream It, You Can Achieve It.” Parent Memorable Messages As Indicators Of College Student Success, Haley Kranstuber, Kristen Carr, Angela M. Hosek

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

This study investigated various aspects of parents’ memorable messages about college as they relate to indicators of college student success. Findings revealed that parents’ memorable messages about college focused on working (and playing) hard, the necessity of attending college, providing encouragement and support, and general advice based on parents’ own experiences. Although these message themes were not uniquely predictive of college student success, the students’ perceptions of message and sender characteristics emerged as significant predictors of cognitive learning indicators, learner empowerment, college motivation, and satisfaction with college. Theoretical and practical implications for findings are discussed.

Bibliographic Control Of Publications: The Impact On African Countries, Anthony Agena Igbashal, Jacob F. Tsegba

Library Philosophy and Practice (e-journal)

African continent is full of written culture and activities being produced and preserved by her people, not only for posterity but for academics, students and the larger bibliographic communities. That information is generated on the face of African continent on daily bases is not in doubt as printing and publishing has become the order of the day. Libraries and information centers are expected to record and make available all that is written on request. Bibliographic control has become a major determinant of book accessibility and utilization and a key factor to information search. In many countries of the world, individuals …

Employers’ Expectations Of Library Education In Nigeria, Adam Gambo Saleh

Library Philosophy and Practice (e-journal)

Library Education in Nigeria was very much tied up with the general social and political history of the Country. As such, those who aspired to become librarians went to Britain to qualify for the Associate of the Library Association (ALA). However, with the attainment of independence in 1960, the country witnessed the establishment of educational institutions at various levels. The first Library school was established at University College Ibadan in 1960.

Prior to 1960, the Carnegie Corporation has sponsored two studies (Margaret Wrong in 1939 and Ethel Fagan in 1940) to survey the Library needs of West Africa with the …

Correlates Of Homeless Episodes Among Indigenous People, Les B. Whitbeck, Devan M. Crawford, Kelley J. Sittner Hartshorn

Department of Sociology: Faculty Publications

This study reports the correlates of homeless episodes among 873 Indigenous adults who are part of an ongoing longitudinal study on four reservations in the Northern Midwest and four Canadian First Nation reserves. Descriptive analyses depict differences between those who have and have not experienced an episode of homelessness in their lifetimes. Multivariate analyses assess factors associated with a history of homeless episodes at the time of their first interview. Results show that individuals with a history of homeless episodes had significantly more individual and family health, mental health, and substance abuse problems. Periods of homelessness also were associated with …

Macrostructure From Microstructure: Generating Whole Systems From Ego Networks, Jeffrey A. Smith

Department of Sociology: Faculty Publications

This paper presents a new simulation method to make global network inference from sampled data. The proposed simulation method takes sampled ego network data and uses Exponential Random Graph Models (ERGM) to reconstruct the features of the true, unknown network. After describing the method, the paper presents two validity checks of the approach: the first uses the 20 largest Add Health networks while the second uses the Sociology Coauthorship network in the 1990’s. For each test, I take random ego network samples from the known networks and use my method to make global network inference. I find that my method …

Synthesizing Parasitology With Archaeology In Paleopathology, Karl Reinhard, Adauto Araujo

Karl Reinhard Publications

Parasitology is the study of organisms that are symbiotic with other organisms. In this form of symbiosis, the parasite species by definition benefits from the interaction while the host is harmed to some degree. In actuality, some parasites benefit their hosts. The animals traditionally studied by parasitologists range from protozoa to arthropods, and include all types of internal and external worms. Ticks, fleas, lice, and a variety of insects that transmit parasites are also studied by parasitologists. Recently, a more holistic view of parasitism appeared, including bacteria and viruses. In essence, parasitology is the study of a certain kind of …

Zoonotic And Human Parasites Of Inhabitants Of Cueva De Los Muertos Chiquitos, Rio Zape Valley, Durango, Mexico, F. Agustín Jiménez-Ruiz, Scott Lyell Gardner, Adauto Araújo, Martín Horacio Fugassa, Richard H. Brooks, Elizabeth Racz, Karl J. Reinhard

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

We present the first reconstruction of the parasitoses among the people of the Loma San Gabriel culture, as represented by 36 coprolites excavated from the Cueva de los Muertos Chiquitos in Durango, Mexico. The coprolites date to approximately 1,400-yr ago. Species identified based on eggs recovered include the trematode Echinostoma sp., the tapeworms Hymenolepis sp. and Dipylidium caninum, and the nematodes Ancylostoma duodenale, Enterobius vermicularis, and Trichuris trichiura. After rehydration and screening, 2 methods were used to recover eggs from these samples including spontaneous sedimentation and flotation. Samples were analyzed by 3 different laboratories for independent …

The ‘Friendship Dynamics Of Religion,’ Or The ‘Religious Dynamics Of Friendship’? A Social Network Analysis Of Adolescents Who Attend Small Schools, Jacob Cheadle, Philip Schwadel

Department of Sociology: Faculty Publications

Longitudinal social network data on adolescents in seven schools are analyzed to reach a new understanding about how the personal and interpersonal social dimensions of adolescent religion intertwine together in small school settings. We primarily address two issues relevant to the sociology of religion and sociology in general: (1) social selection as a source of religious homophily and (2) friend socialization of religion. Analysis results are consistent with Collins’ interaction ritual chain theory, which stresses the social dimensions of religion, since network–religion autocorrelations are relatively substantial in magnitude and both selection and socialization mechanisms play key roles in generating them. …

Social Class And Finding A Congregation: How Attendees Are Introduced To Their Congregations, Philip Schwadel

Department of Sociology: Faculty Publications

Despite the large numbers of Americans switching religious congregations each year, social scientists know relatively little about how people are introduced to new religious congregations. In this research note, I use multiple surveys of congregants—two surveys of Presbyterians in the 1990s and a survey of attendees from a random sample of congregations in 2001—to examine the effects of education and income on how attendees are introduced to their religious congregations. Results show that education and income are key predictors of how attendees find their congregations. In general, Americans with low levels of education and income are disproportionately likely to be …

Book Review: Making Chastity Sexy: The Rhetoric Of Evangelical Abstinence Campaigns, By Christine J. Gardner, Kelsy Burke

Department of Sociology: Faculty Publications

Evangelical messages about adolescent sexuality appear straight-forward: unless they are married (and heterosexual), teens should not have sex. However, as communications scholar Christine J. Gardner shows in her book, Making Chastity Sexy: The Rhetoric of Evangelical Abstinence Campaigns, how evangelicals go about promoting abstinence is both complicated and unexpected. Gardner focuses on how social meanings about religion and sexuality are constructed in evangelical abstinence campaign by examining the rhetoric of three U.S. campaigns (the primary focus of the book) and one African campaign. One of her most surprising findings—and the one for which the book’s title is based—is that U.S. …

Does The Reason Matter? Variations In Childlessness Concerns Among U.S. Women, Julia Mcquillan, Arthur L. Greil, Patricia Wonch Hill, Kari C. Gentzler, John D. Hathcoat

Department of Sociology: Faculty Publications

Does the reason why women have no children matter with regard to level of childlessness concerns? Reasons include biomedical barriers, situational barriers, delaying motherhood, and choosing to be childfree. The concept of ‘‘childlessness concerns’’ captures the idea that holidays and family gatherings are difficult because of not having children or feeling left out or sad that others have children. Life course and identity theories guided the structural equation model analyses of a representative sample of 1,180 U.S. women without children from the National Survey of Fertility Barriers. The results indicated that women with the least control over pregnancy, those with …

The Intergenerational Effects Of Relocation Policies On Indigenous Families, Melissa L. Walls, Les B. Whitbeck

Department of Sociology: Faculty Publications

This research utilizes life-course perspective concepts of linked lives and historical time and place to examine the multigenerational effects of relocation experiences on Indigenous families. Data were collected from a longitudinal study currently underway on four American Indian reservations in the Northern Midwest and four Canadian First Nation reserves where residents share a common Indigenous cultural heritage. This paper includes information from 507 10 – 12 year old Indigenous youth and their biological mothers who participated in the study. Results of path analysis revealed significant direct and indirect effects whereby grandparent-generation (G1) participation in government relocation programs negatively impacts not …

Conditioned Response Evoked By Nicotine Conditioned Stimulus Preferentially Induces C-Fos Expression In Medial Regions Of Caudate-Putamen, Sergios Charntikov, Matthew E. Tracy, Changjiu Zhao, Ming Li, Rick A. Bevins

Department of Psychology: Faculty Publications

Nicotine has both unconditioned and conditioned stimulus properties. Conditioned stimulus properties of nicotine may contribute to the tenacity of nicotine addiction. The purpose of this experiment was to use neurohistochemical analysis of rapidly developing c-Fos protein to elucidate neurobiological loci involved in the processing of nicotine as an interoceptive conditioned stimulus (CS). Rats were injected (SC) in an intermixed fashion with saline or nicotine (16 sessions of each) and placed in conditioning chambers where they were given one of the three conditions depending on group assignment: (a) nicotine paired 100% of the time with intermittent access to sucrose (nicotine-CS condition), …

Gender Differences In Head Impacts Sustained By Collegiate Ice Hockey Players, Lindley L. Brainard, Jonathan G. Beckwith, Jeffrey J. Chu, Joseph J. Crisco, Thomas W. Mcallister, Ann-Christine Duhaime,, Arthur C. Maerlender, Richard M. Greenwald

Department of Psychology: Faculty Publications

Purpose—This study aims to quantify the frequency, magnitude, and location of head impacts sustained by male and female collegiate ice hockey players over two seasons of play.

Methods—Over two seasons, 88 collegiate athletes (51 female, 37 male) on two female and male NCAA varsity ice hockey teams wore instrumented helmets. Each helmet was equipped with 6 single-axis accelerometers and a miniature data acquisition system to capture and record head impacts sustained during play. Data collected from the helmets were post-processed to compute linear and rotational acceleration of the head as well as impact location. The head impact exposure data (frequency, …

Disentangling The Nature Of The Nicotine Stimulus, Rick A. Bevins, Scott T. Barrett, Robert J. Polewan, Steven T. Pittenger, Natashia Swalve, Sergios Charntikov

Department of Psychology: Faculty Publications

Learning involving interoceptive stimuli likely plays an important role in many diseases and psychopathologies. Within this area, there has been extensive research investigating the interoceptive stimulus effects of abused drugs. In this pursuit, behavioral pharmacologists have taken advantage of what is known about learning processes and adapted the techniques to investigate the behavioral and receptor mechanisms of drug stimuli. Of particular interest is the nicotine stimulus and the use of the two-lever operant drug discrimination task and the Pavlovian drug discriminated goal-tracking task. There is strong concordance between the two methods when using “standard” testing protocols that minimize learning on …

Contributions Of Dynamic Systems Theory To Cognitive Development, John P. Spencer, Andrew Austin, Anne R. Schutte

Department of Psychology: Faculty Publications

This paper examines the contributions of dynamic systems theory to the field of cognitive development, focusing on modeling using dynamic neural fields. A brief overview highlights the contributions of dynamic systems theory and the central concepts of dynamic field theory (DFT). We then probe empirical predictions and findings generated by DFT around two examples—the DFT of infant perseverative reaching that explains the Piagetian A-not-B error, and the DFT of spatial memory that explain changes in spatial cognition in early development. A systematic review of the literature around these examples reveals that computational modeling is having an impact on empirical research …

Neural Mechanisms Underlying Neurooptometric Rehabilitation Following Traumatic Brain Injury, Caitlin M. Hudac, Srinivas Kota, James L. Nedrow, Dennis L. Molfese

Department of Psychology: Faculty Publications

Mild to severe traumatic brain injuries have lasting effects on everyday functioning. Issues relating to sensory problems are often overlooked or not addressed until well after the onset of the injury. In particular, vision problems related to ambient vision and the magnocellular pathway often result in posttrauma vision syndrome or visual midline shift syndrome. Symptoms from these syndromes are not restricted to the visual domain. Patients commonly experience proprioceptive, kinesthetic, vestibular, cognitive, and language problems. Neurooptometric rehabilitation often entails the use of corrective lenses, prisms, and binasal occlusion to accommodate the unstable magnocellular system. However, little is known regarding the …
