Feldman, Kerrigan B. Gilbert, John G. Hodge, J. Steen Hoyer, Andy Lin, Suxing Liu, César Lizárraga, Argelia Lorence, Michael Miller, Eric Platon, Monica Tessman, Tony Sax

Department of Agronomy and Horticulture: Faculty Publications

Systems for collecting image data in conjunction with computer vision techniques are a powerful tool for increasing the temporal resolution at which plant phenotypes can be measured non-destructively. Computational tools that are flexible and extendable are needed to address the diversity of plant phenotyping problems. We previously described the Plant Computer Vision (PlantCV) software package, which is an image processing toolkit for plant phenotyping analysis. The goal of the PlantCV project is to develop a set of modular, reusable, and repurposable tools for plant image analysis that are open-source and community-developed. Here we present the details and rationale for major …

Engineering Professors’ Perspectives On Gender And Assessment Of Teamwork, Kacey Beddoes, Grace Panther

Department of Civil and Environmental Engineering: Faculty Publications

Teamwork is an important component of engineering education programs; however, when not facilitated well, it can be a site of gender biases. The aim of this article is to thematically explore what and how engineering professors think about gender in the assessment of teamwork. In 2014 and 2015, semi-structured interviews were conducted with 39 engineering professors in the United States. Interviews covered a wide range of topics, with one section of the interviews devoted to teamwork specifically. For this article, the parts of the interviews about assessment of teamwork are analyzed. It was found that most participants were unaware of …

‘Why I Sent My Child Away’: Culturally Structured Motivations For Long-Distance Parenting, Deepa Srivastava, Maria Rosario De Guzman

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

Although long-distance parenting is often depicted as a response to crisis (e.g., economic) or other stressful life events, it is sometimes undertaken in various culturally normative situations. This current study explores the motivations of South Asian Indian immigrant parents for sending their young children to India to live temporarily with their grandparents. This qualitative study involves in-depth interviews with first generation immigrant parents about their experiences and motivations for sending their children to India. Analysis of the data revealed five themes, namely, (a) contextual and daily challenges in caring for their children in the United States, (b) parents’ concern around …

Incorporating Sociocultural Phenomena Into Ecosystem-Service Valuation: The Importance Of Critical Pluralism, Carena J. Van Riper, Amanda J. Landon, Sarah Kidd, Patrick Bitterman, Lee A. Fitzgerald, Elise F. Granek, Sonia Ibarra, David M. Iwaniec, Christopher M. Raymond, David Toledo

Geography Program: Faculty Publications

Ecosystem-services scholarship has largely focused on monetary valuation and the material contributions of ecosystems to human well-being. Increasingly, research is calling for a deeper understanding of how less tangible, nonmaterial values shape management and stakeholder decisions. We propose a framework that characterizes a suite of sociocultural phenomena rooted in key social science disciplines that are currently underrepresented in the ecosystem-services literature. The results from three example studies are presented to demonstrate how the tenets of this conceptual model can be applied in practice. We consider the findings from these studies in light of three priorities for future research: (1) complexities …

Palynological Investigation Of Mummified Human Remains, Karl Reinhard, Marina Milanello Do Amaral, Nicole Wall

Karl Reinhard Publications

Pollen analysis was applied to a mummified homicide victim in Nebraska, U.S.A., to determine the location of death. A control sample showed the normal ambient pollen in the garage crime scene. Ambient windborne types, common in the air of the region, dominated the control. Internal samples were analyzed from the sacrum, intestine, and diaphragm. Microfossils were recovered from the rehydrated intestine lumen. The intestinal sample was dominated by Brassica (broccoli). The sacrum sample was high in dietary types but with a showing of ambient types. The pollen from the diaphragm was dominated by ambient pollen similar to the control samples. …

Pseudoscorpions Of The Family Cheiridiidae (Arachnida: Pseudoscorpiones) Recovered From Burial Sediments At Pachacamac (500–1,500ce), Peru, Johnica J. Morrow, Livia Taylor, Lauren Peck, Christian Elowsky, Lawrence Stewart Owens, Peter Eeckout, Karl Reinhard

Karl Reinhard Publications

Fragmented remains of pseudoscorpions belonging to the family Cheiridiidae (Arachnida, Pseudoscorpiones) were recovered from Ychsma polity (c. AD 1000–1475) burial sediments from Pachacamac, Peru. Sediments from 21 burials were examined following rehydration in 0.5% trisodium phosphate for 48 h and subsequent screening through a 250 lm mesh. Materials larger than 250 lm were surveyed for the presence of arthropods. A total of two samples contained pseudoscorpion fragments, which were collected and quantified to determine the minimal number of pseudoscorpions present per gram of each sample. Following quantification, pseudoscorpion specimens were imaged utilizing confocal laser scanning microscopy (CLSM) to assist with …

Checking Privilege At The Door: Men’S Reflections On Masculinity In Women’S And Gender Studies Course, Rachel Schmitz, Emily Kazyak

Department of Sociology: Faculty Publications

Certain types of masculinity undergird gender inequality, but different contexts may encourage individuals to conceptualize gender in new and unique ways. Women’s and Gender Studies (WGS) university courses support this for women, but less is known about men’s experiences. Through an analysis of interview data from 15 men who have taken WGS courses, we ask: What do men experience in the WGS classroom and how do men perceive that their experiences in WGS courses shape their conceptualizations of gender and gender relations? Men described developing their understandings of gender inequality after taking a WGS course and they applied this knowledge …

Democratizing Academic Journals: Technology, Services, And Open Access, Scholastica, Danielle Padula, Björn Brembs, Stevan Harnad, Ulrich Herb, Roxanne Missingham, Dan Morgan, John Ortbal

Copyright, Fair Use, Scholarly Communication, etc.

This white paper delves into:

• The past and present state of journal publishing

• Current alternatives to the corporate publisher model

• Steps to realize sustainable, open access-friendly journal models of the future

This paper argues democratization of journal publishing is the key to lowering journal production costs and facilitating OA. Members of the academic community, either at established not-for-profit organizations or through informal groups of editors and advocates, must break up the corporate publisher conglomerate by taking control of journals and developing funding, access, and distribution models that work for their disciplines. This paper explores how widespread adoption …

Social Factors, Alcohol Expectancy, And Drinking Behavior: A Comparison Of Two College Campuses, Kimberly A. Tyler, Rachel M. Schmitz, Scott A. Adams, Leslie Gordon Simons

Department of Sociology: Faculty Publications

Background: Though college students have high rates of heavy drinking, few studies have examined the various pathways through which risks affect drinking and whether this varies by institution. We examined whether alcohol expectancy mediates the relationship between social factors (i.e., hooking up, friends drinking, Greek affiliation, entitlement) and drinking behavior comparing college students from one Midwestern and one Southeastern university. Methods: In the 2013–14 academic year, 1,482 college students (51% female) enrolled in undergraduate courses at two public universities completed a paper and pencil survey of attitudes and experiences about dating, sexuality, and substance use. Multiple group path …

Using Cell Phones For Data Collection: Benefits, Outcomes, And Intervention Possibilities With Homeless Youth, Kimberly A. Tyler, Rachel M. Schmitz

Department of Sociology: Faculty Publications

While many homeless youth use cell phones to stay socially connected, and maintaining positive social ties can contribute to pathways out of homelessness, little is known about how using cell phones for data collection can improve these young people’s lives. We conducted baseline and follow-up interviews with 150 homeless youth as well as provided them with a cell phone for 30 days to gather daily data using short message service (SMS) surveying. This paper examines youths’ opinions about study participation and how they used the cell phone. Results revealed that youth liked participating in the study because the SMS texting …

Lgbtq+ Young Adults On The Street And On Campus: Identity As A Product Of Social Context, Rachel M. Schmitz, Kimberly A. Tyler

Department of Sociology: Faculty Publications

Lesbian, gay, bisexual, queer, and other sexual and gender minority (LGBTQ+) young adults face unique identity-related experiences based on their immersion in distinctive social contexts. The predominant framework of performing separate analyses on samples of LGBTQ+ young people by their primary social status obfuscates more holistic understandings of the role of social context. Using 46 in-depth interviews with LGBTQ+ college students and LGBTQ+ homeless young adults, we ask: How are LGBTQ+ young adults’ capacities for “doing” their gender and sexual identities shaped by their distinctive social contexts? In developing their identities, both groups of LGBTQ+ young adults navigated their social …

“I Wanted To Raise My Hand And Say I’M Not A Feminist”: College Men’S Use Of Hybrid Masculinities To Negotiate Attachments To Feminism And Gender Studies, Rachel Schmitz, Trenton M. Haltom

Department of Sociology: Faculty Publications

Using a hybrid masculinities framework, we qualitatively analyzed 15 college men’s experiences with feminism and gender scholarship in Women’s and Gender Studies (WGS) courses. Men described adopting particular strategies of discourse in their social interactions to manage varied reactions to feminism and gender studies. As a way of justifying their choice of academic study, these men also learned to navigate social relationships by highlighting or downplaying their own masculinity (i.e., creating or deconstructing a hybrid masculinity). Finally, men reconciled the multiple meanings of feminism and WGS studies by drawing from dominant cultural norms and expectations in attempts to make sense …

The Positives And Negatives Of Higher Education: How The Religious Context In Adolescence Moderates The Effects Of Education On Changes In Religiosity, Philip Schwadel

Department of Sociology: Faculty Publications

Although longitudinal research suggests that declines in religiosity associated with higher education vary across religious traditions, it tells us little about variation in the effects of higher education on changes in religiosity more broadly. Higher education may promote increases in religiosity for some, particularly with many Americans now being raised in relatively secular homes. This research note uses multilevel growth curve models and four waves of longitudinal data to examine how the religious context in adolescence moderates the effects of higher education on changes in emerging adult religiosity, regardless of the direction of change. Religious tradition and parent religious service …

Changes In Male Hunting Returns, Raymond B. Hames

Department of Anthropology: Faculty Publications

Research on changes in male hunting among hunter-gatherers addresses two important issues in early human evolution: the nature of the family and trade-offs in mating and parenting effort as well as the development of embodied capital. In the hunter-gatherer literature, there is a debate about the function of male hunting that has implications for understanding the role males play in the evolution of the pair bond. The traditional model argues that male hunting and other economic activities are forms of male provisioning or parenting effort designed to enhance a man’s fitness through his wife’s reproduction and the survivorship of their …

Heteroglossic Practices In A Multilingual Science Classroom, Lydiah Kananu Kiramba

Department of Teaching, Learning, and Teacher Education: Faculty Publications

This paper uses sociocultural theories of language learning to investigate how teachers and students navigate between monolingual institutional policies and the multilingual realities encountered in a rural Kenyan fourth-grade classroom. The paper addresses not only how learners’ communicative repertoires are deployed to make meaning in a foreign language instruction context but also the sociocultural significance of these communicative practices. Results illustrate how the science teacher used heteroglossic practices to mediate students’ access to literacy, hence, supporting the content learning and language development of students. Both the science teacher and the students preferred a more flexible use of language to make …

Relocation Redux: Labrador Inuit Population Movements And Inequalities In The Land Claims Era, Kirk Dombrowski, Patrick Habecker, G. Robin Gauthier, Bilal Khan, Joshua Moses

Department of Sociology: Faculty Publications

The importance of community relocation experiences for aboriginal land claims movements is well documented; the role played by successful land claims in prompting ongoing out-migration is not. Data collected in 2011 on the lives of migrants are used to test three hypotheses: H1, Inuit leaving the land claims area for a nearby nonaboriginal city show markedly different social outcomes based on the length of time since migration; H2, these social outcomes map onto patterns of intergroup boundaries in their new communities; and H3, both of these outcomes are better explained by migration patterns after the land claims than by the …

Metal And Glass: An Investigation Of Possible Historic Period Native American Sites In Wind Cave National Park, Morgan C. Beyer

Department of Anthropology: Theses and Student Research

The Black Hills region was one of the last areas of the American West where Native tribes were able to escape the intervention of the federal government. Because of this and the cultural ties that many Plains Indian tribes hold to the area, this region would seem to be one where non-reservation historic period Native American sites are abundant. The goals of this research were to identify markers that could be utilized by archaeologists to differentiate Native American sites and Euro American sites from the same historic time period in the Black Hills Region, positively identify the occupation of certain …

Illuminating Hopewell Legacy Data: A Case Study Of Mound 23 At Hopewell Mound Group, Margaret Robinson

Department of Anthropology: Theses and Student Research

Digital archives present new opportunities for transparency, context and accessibility by digitizing and publishing limitedly accessible collections of archival documents and artifacts. Due to the destructive nature of archaeological inquiry these datasets are the only remaining materials from which archaeologists can make interpretations about past human behavior. The objective of this thesis was to be a case study for the usability of legacy data from Hopewell Mound Group by examining newly accessible data sources through the Ohio Hopewell digital archive (hopewell.unl.edu). The resulting databases for the burial data and artifacts of Hopewell Mound Group’s Mound 23 are a combination of …

Climate Change And The Integrity Of Science, Peter H. Gleick, James L. Van Etten, Members Of The U.S. National Academy Of Sciences

James Van Etten Publications

We are deeply disturbed by the recent escalation of political assaults on scientists in general and on climate scientists in particular. All citizens should understand some basic scientific facts. There is always some uncertainty associated with scientific conclusions; science never absolutely proves anything. When someone says that society should wait until scientists are absolutely certain before taking any action, it is the same as saying society should never take action. For a problem as potentially catastrophic as climate change, taking no action poses a dangerous risk for our planet.

Scientific conclusions derive from an understanding of basic laws supported by …

Infertility And Fertility Intentions, Desires, And Outcomes Among Us Women, Karina M. Shreffler, Stacy Tiemeyer, Cassandra Dorius, Tiffany Spierling, Arthur L. Greil, Julia Mcquillan

Department of Sociology: Faculty Publications

BACKGROUND AND OBJECTIVE Little is known about how the experience of infertility or identification as someone with infertility shapes women’s fertility intentions, desires, or birth outcomes. The purpose of this paper is to help fill this gap in knowledge for fertility-intentions research.

METHODS Using data from the National Survey of Fertility Barriers (NSFB), we use linear and logistic regression methods to assess how infertility and parity statuses are associated with fertility intentions and desires, as well as how statuses at one point in time predict birth three years later.

RESULTS We find that infertility is associated with lower fertility intentions. …

Assessing The Archaeoparasitological Potential Of Quids As A Source Material For Immunodiagnostic Analyses, Johnica J. Morrow, Karl Reinhard

Karl Reinhard Publications

In the present study, quids from La Cueva de los Muertos Chiquitos (CMC) were subjected to ELISA tests for 2 protozoan parasites, Toxoplasma gondii (n=45) and Trypanosoma cruzi (n=43). The people who occupied CMC, the Loma San Gabriel, lived throughout much of present-day Durango and Zacatecas in Mexico. The known pathoecology of these people puts them into at-risk categories for the transmission of T. gondii and T. cruzi. Human antibodies created in response to these 2 parasites can be detected in modern saliva using ELISA kits intended for use with human serum. For these reasons, quids were reconstituted and …

Prehistoric Pathoecology As Represented By Parasites Of A Mummy From The Peruaçu Valley, Brazil, Karl Reinhard, Adauto Araújo

Karl Reinhard Publications

Paleopathologists have begun exploring the pathoecology of parasitic diseases in relation to diet and environment. We are summarizing the parasitological findings from a mummy in the site of Lapa do Boquete, a Brazilian cave in the state of Minas Gerais. These findings in context of the archaeology of the site provided insights into the pathoecology of disease transmission in cave and rockshelter environments. We are presenting a description of the site followed by the evidence of hookworm, intestinal fluke, and Trypanosoma infection with resulting Chagas disease in the mummy discovered in the cave. These findings are used to reconstruct the …

Temporal And Spatial Distribution Of Enterobius Vermicularis (Nematoda: Oxyuridae) In The Prehistoric Americas, Karl J. Reinhard, Adauto Araújo, Johnica J. Morrow

Karl Reinhard Publications

Investigations of Enterobius sp. infection in prehistory have produced a body of data that can be used to evaluate the geographic distribution of infection through time in the Americas. Regional variations in prevalence are evident. In North America, 119 pinworm positive samples were found in 1,112 samples from 28 sites with a prevalence of 10.7%. Almost all of the positive samples came from agricultural sites. From Brazil, 0 pinworm positive samples were found in 325 samples from 7 sites. For the Andes region, 22 pinworm positive samples were found in 411 samples from 26 sites for a prevalence of 5.3%. …
