Insights From The Inclusive Environments And Metrics In Biology Education And Research Network: Our Experience Organizing Inclusive Biology Education Research Events, Rebecca A. Campbell-Montalvo, Natalia Caporale, Gary S. Mcdowell, Candice Idlebird, Katie M. Wiens, Kimberly M. Jackson, Jana D. Marcette, Michael E. Moore

Department of Biochemistry: Faculty Publications

In contrast to efforts focusing on improving inclusion in STEM classrooms from kindergarten through un-dergraduate (K–16), efforts to improve inclusion in scientific meetings and conferences, important hubs of STEM culture, are more recent. Markers of inclusion that are sometimes overlooked at these events can include the composition of panels, how workshops are run, the affordability of conferences, and various other mechanisms that maintain pre-existing hierarchies and norms that limit the participation of early-career researchers and individuals of minoritized cultural, linguistic, and economic backgrounds. The Inclusive Environments and Metrics in Biology Education and Research (iEMBER) network coordinates efforts of researchers from …

A Global Database Of Soil Nematode Abundance And Functional Group Composition, Johan Van Den Hoogen, Stefan Geisen, Thomas W. Crowther, Peter Mullin, Many Co-Authors

Department of Plant Pathology: Faculty Publications

As the most abundant animals on earth, nematodes are a dominant component of the soil community. They play critical roles in regulating biogeochemical cycles and vegetation dynamics within and across landscapes and are an indicator of soil biological activity. Here, we present a comprehensive global dataset of soil nematode abundance and functional group composition. This dataset includes 6,825 georeferenced soil samples from all continents and biomes. For geospatial mapping purposes these samples are aggregated into 1,933 unique 1-km pixels, each of which is linked to 73 global environmental covariate data layers. Altogether, this dataset can help to gain insight into …

Transformative Power Of Stitchery: Sashiko From Cold Regions Of Japan And Embroidery Work Of The Nui Project, Yoshiko Iwamoto Wada

Textile Society of America: Symposium Proceedings

This paper seeks to reveal the transformative power of stitchery by examining textile practices in Japan and articulating how a threaded needle can be viewed as the co-agent of stitchers, infusing their materials with properties in a “processual” and relational manner that reflects the currents of their lifeworld.^[1] I will contrast and compare two practices, one ancient and one modern, one responding to life’s necessities and the other simply to the act of stitching. In the ancient world, stitchery was essential for human survival, and later in rural Japan, sashiko stitchery was a medium that connected textiles with daily …

Where Can Objects Take You? The Case Of The World War Ii Japanese Airman's Suit, Madelyn Shaw, Trish Fitzsimons

Textile Society of America: Symposium Proceedings

“Dad always said that ‘It’s made out of Australian wool,’ and I thought that was just a joke because you couldn’t see how the Japanese would get hold of Australian wool during the war…. But it is a fine material…. They weren’t scrapping for something to wear.” —Wally Lanagan

In December 1942, the Yokosuka Military Department manufactured, surely among hundreds of others, a flying suit, which may or may not have ever been worn by a Japanese pilot. It did, however, end up on display at the Pioneer Park Museum in Dalby, a small town in rural Queensland, Australia. It …

Viscacha: Luxury, Fate And Identification In Precolumbian Textiles, Elena Phipps, Caroline Solazzo

Textile Society of America: Symposium Proceedings

Since the sixteenth century, references by Spanish chroniclers to the use of chinchilla hair (Andean rodents of several species including viscacha) by Andean weavers indicate that the fine hair of these animals had been incorporated into textiles. Their fine soft hair, often mottled in color, has distinctive characteristics which vary and, as a result, make them difficult to identify. Some archaeological finds, primarily in Chile have reported viscacha skins and fur bags, but few if any reports have identified the presence of textiles or spun yarns that incorporate this special fiber. The depiction of the animal takes on special meaning …

Nutritional Value Of Crops Affected By Elevated Carbon Dioxide Concentrations In Atmospheric Conditions, Alex Joseph Cusimano

Department of Environmental Studies: Undergraduate Student Theses

This research was conducted to evaluate the effects of rising atmospheric carbon dioxide concentrations, and the nutritional quality of crops. Using Free Air CO2 Enrichment (FACE) and Decision Support System for Agrotechnology Transfer (DSSAT) to simulate elevated carbon dioxide levels, more review of previous literature was studied. Studies found that although there is a negative loss of nutrient availability, there are major signs that nutrient deficiencies. Nitrogen(protein), Iron, and Zinc are the most impacted with elevated atmospheric CO2 conditions. Further research and experiments regarding long term plant growth should be considered moving forward. With only limted situations and different CO2 …

Book Review: Neha Vora, Teach For Arabia: American Universities, Liberalism, And Transnational Qatar, Loukia K. Sarroub

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

With a provocative title that inherently questions who might be served and educated best by the branch campuses of top US universities in Qatar and Gulf states, Vora’s new book debunks some old myths and reminds readers from the outset that “liberalism has Arabian roots” (18). Vora wonders about and studies the transplant of liberal education into “so-called illiberal” countries like Qatar and other Gulf States. Her timely book offers on-the-ground perspectives of students and faculty in these transplant institutions as they engage with curriculum and one another in a new knowledge economy. The book contributes to scholarship about how …

Identity Negotiation In Multilingual Contexts: A Narrative Inquiry Into Experiences Of An African Immigrant High School Student, Lydiah Kananu Kiramba, James Oloo

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

Background/Context: Inclusion of African immigrant youth voices in educational and research discourses remains rare despite the steady growth of this population in the United States over the past four decades. Consequently, the multilingual abilities of these youth remain typically unnoticed or ignored in the classroom, and little is specifically known about their histories, cultures, expectations, and achievements.

Purpose: Using the narrative inquiry approach and the Natural, Institutional, Discursive, Affinity, Learner, and Solidarity (NIDALS) theoretical lens, we explore the lived experiences of one African immigrant high school student in the Midwestern United States.

Research Design: Using narrative inquiry (Clandinin & Connelly, …

Competing Forces Of Withdrawal And Disease Avoidance In The Risk Networks Of People Who Inject Drugs, Elspeth Ready, Patrick Habecker, Roberto Abadie, Bilal Khan, K. Dombrowski

Department of Sociology: Faculty Publications

We analyze a network of needle-sharing ties among 117 people who inject drugs (PWID) in rural Puerto Rico, using exponential random graph modeling to examine whether network members engage in partner restriction to lower their risk of contracting HIV or hepatitis C (HCV), or in informed altruism to prevent others from contracting these infections. Although sharing of used syringes is a significant risk factor for transmission of these diseases among PWID, we find limited evidence for partner restriction or informed altruism in the network of reported needle-sharing ties. We find however that sharing of needles is strongly reciprocal, and individuals …

Contextualizing The Covid-19 Era In Puerto Rico: Compounding Disasters And Parallel Pandemics, Catherine Garcia, Fernando I. Rivera, Marc A. Garcia, Giovani Burgos, María P. Aranda

Department of Sociology: Faculty Publications

Objectives: The COVID-19 outbreak has worsened the ongoing economic crisis in Puerto Rico by creating "parallel pandemics" that exacerbate socioeconomic and health inequalities experienced by its most vulnerable residents. Unfortunately, conditions on the island have been largely overlooked by national media outlets and the mainland U.S. population. Thus, this research report aims to draw attention to the disparate burden multiple and compounding disasters have on older island-dwelling Puerto Rican adults’ health and well-being.

Methods: We characterize the lived experiences of the older population in Puerto Rico by incorporating data from numerous sources and contextualizing the effects of compounding disasters, the …

A particular focus was understanding whether the socio-collaborative environment facilitated by the learning commons was aligned with the institutional objectives of supporting intensive study and scholarly work.

Methods – A mixed methods sequential explanatory study design was used, in which quantitative findings were supplemented by qualitative findings. Data for the study were drawn from 59 hours of observations documenting behaviors of 9,249 individuals, as well as survey responses from 302 students. Three semi-structured focus groups with 10 students …

Examining Glocal Scales And Mapping Literacy Landscapes: What We Can Learn As Ethnographers Through Geospatial Analyses, Loukia K. Sarroub, William R. England

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

Operationalizing space is challenging because the factors impacting education are often located at different scales. Combining Geographic Information Systems and ethnographic analyses allows researchers to conduct studies at both micro- and macro-scales, thus illuminating the connections between local and global phenomena. In our first case, we analyze refugee migration at multiple scales in order to better understand and contextualize refugee mobility. In case two we measure ‘literacy landscapes’ at the state- and district-level by mapping clusters of high/low standardized reading scores. Hot spot and cold spot analyses show that standardized reading scores are implicitly connected to socioeconomic status and are …

Institutional Responses To Events Challenging Campus Climates: Examining The Power In Language, Crystal Garcia, Benjamin Arnberg, Jessica Weise, Marit Winborn

Department of Educational Administration: Faculty Publications

This qualitative study explored administrative responses to local and sociopolitical events challenging campus climates at public research universities. Using critical discourse analysis, we examined the use of language as a form of power in publicly available documents addressing campus climate for diversity and inclusion at 31 U.S. institutions. Findings center 3 themes: underlying power in determining what to address; the power of language in perpetuating or deconstructing power, privilege, and oppression; and the distinction between espousing and enacting commitments to diversity, equity, and inclusion. Implications for research and practice are discussed.

Training For Specialists Vs. Education For Agroecologists, Charles A. Francis

Department of Agronomy and Horticulture: Faculty Publications

I admit to being a slow learner. Graduate school training in agronomy at the University of California, Davis and in plant breeding at Cornell University provided me with top-quality opportunities to acquire the tools for crop improvement, plus the contacts to join professionals at the International Center for Tropical Agriculture in Colombia. As a young scientist dedicated to building on successes of the Green Revolution, I was convinced that genetic changes would solve global hunger. This had been amply demonstrated with the yield increases of wheat in Mexico and India, and with rice in Southeast Asia. Should this success not …

Innovative Teaching Knowledge Stays With Users, A. Kelly Lane, Jacob D. Mcalpin, Brittnee Earl, Stephanie Feola, Jennifer E. Lewis, Karl Mertens, Susan E. Shadle, John Svoretz, John P. Ziker, Brian A. Couch, Luanna B. Prevost, Marilyne Stains

School of Biological Sciences: Faculty Publications

Programs seeking to transform undergraduate science, technology, engineering, and mathematics courses often strive for participating faculty to share their knowledge of innovative teaching practices with other faculty in their home departments. Here, we provide interview, survey, and social network analyses revealing that faculty who use innovative teaching practices preferentially talk to each other, suggesting that greater steps are needed for information about innovative practices to reach faculty more broadly.

Coproid Predicts The Source Of Coprolites And Paleofeces Using Microbiome Composition And Host Dna Content, Maxime Borry, Bryan Cordova, Angela Perri, Marsha Wibowo, Tanvi Prasad Honap, Jada Ko, Kate Britton, Linus Girdland-Flink, Robert C. Power, Ingelise Stuijts, Domingo C. Salazar-García, Courtney Hofman, Richard Hagan, Thérèse Samdapawindé Kagoné, Nicolas Meda, Helene Carabin, David Jacobson, Karl Reinhard, Cecil Lewis, Aleksandar Kostic, Choongwon Jeong, Alexander Herbig, Alexander Hübner, Christina Warinner

Karl Reinhard Publications

Shotgun metagenomics applied to archaeological feces (paleofeces) can bring new insights into the composition and functions of human and animal gut microbiota from the past. However, paleofeces often undergo physical distortions in archaeological sediments, making their source species difficult to identify on the basis of fecal morphology or microscopic features alone. Here we present a reproducible and scalable pipeline using both host and microbial DNA to infer the host source of fecal material. We apply this pipeline to newly sequenced archaeological specimens and show that we are able to distinguish morphologically similar human and canine paleofeces, as well as non-fecal …

Diet Analysis Reveals Pre-Historic Meals Among The Loma San Gabriel At La Cueva De Los Muertos Chiquitos, Rio Zape, Mexico (600–800 Ce), Elisa Pucu, Julia Russ, Karl Reinhard

Karl Reinhard Publications

Coprolites have been a source of study for archeologists due to several reasons: they not only provide information on the life and nutritional habits of ancient individuals but also on their health. In this paper, we processed 10 coprolites collected at La Cueva de Los Muertos Chiquitos (600–800 CE), Rio Zape, Mexico, with acetolysis solution for pollen analysis. The number of pollen grains/gram of each coprolite sample was quantified along with the macroscopic remains of these samples. The main food item ingested by the population was maize, followed by Agave. Squash blossoms were also part of their food source …

Pinworm Research In The Southwest Usa: Five Decades Of Methodological And Theoretical Development And The Epidemiological Approach, Morgana Camacho, Karl Reinhard

Karl Reinhard Publications

Pinworms infected Ancestral Pueblo populations since early periods of occupation on the Colorado Plateau. The high prevalence of pinworm found in these populations was correlated with the habitation style developments through time. However, in previous studies, Turkey Pen Cave, an early occupation site, and Salmon Ruins, a late occupation site, exhibited prevalences that were anomalously low, suggesting that these sites were outliers. Alternatively, it is possible that the previous quantification method was not successful in detecting the real prevalence and eggs per gram, which led to inexact interpretations. The aims of this study were to verify if previous pinworm prevalences …

Online Engagement And Overall Performance: Tmfd 123: Clothing & Society Benchmark Portfolio – A Peer Review Of Teaching Portfolio, Claire Nicholas

UNL Faculty Course Portfolios

This benchmark course portfolio examines TMFD 123: Clothing & Society, a large enrollment, online delivery course offered in the Department of Textiles, Merchandising & Fashion Design at the University of Nebraska-Lincoln. In addition to detailed discussion of existing course materials, activities, and assessment tools, the portfolio focuses on the issue of student engagement and peer-to-peer interaction. It also tracks the impact of the introduction of a Yellowdig discussion forum assignment in an effort to boost engagement, create a sense of community, and foster connections between course materials and concepts and students’ everyday lives. The latter objective intersects with several of …

Critical Thinking, Perspective-Taking, And Cultural Humility In Global Refugee Health Studies: A Peer Review Of Teaching Benchmark Portfolio, Julie A. Tippens

UNL Faculty Course Portfolios

This portfolio examines the third iteration of a course I developed for the Department of Child, Youth and Family Studies: CYAF 493 – Global Case Studies in Refugee Health and Wellbeing. The primary goal of this course is for students to think critically about the social and structural determinants of refugee health and wellbeing. I have also integrated three core course values to guide instruction: critical thinking, perspective-taking, and cultural humility. Student learning and engagement was analyzed through four areas: (1) a baseline assessment of students’ perceptions of refugees, (2) weekly homework reflections, (3) a book review assignment, and (4) …

White Women Who Lead: God, Girlfriends, And Diversity Projects In A National Evangelical Ministry, Kelsy Burke, Amy Mcdowell

Department of Sociology: Faculty Publications

A robust body of literature has used feminist analysis to study white evangelical women in the United States, but few of these studies have addressed the reproduction of racial inequality. Beginning with the assumption that women-led evangelical ministries are racialized organizations, the authors examine the relationship between racial and gender ideologies and the messages of white evangelical women leaders at the IF:Gathering, a popular annual Christian women’s conference in the United States. On the surface, the women who lead IF embody a contradiction: they support the conservative gender ideology of evangelicalism while challenging this religious tradition by encouraging all Christian …

Mutual Influence? Gender, Partner Pregnancy Desires, Fertility Intentions, And Birth Outcomes In U.S. Heterosexual Couples, Colleen M. Ray, Sela R. Harcey, Julia Mcquillan, Arthur L. Greil

Department of Sociology: Faculty Publications

Competing hypotheses exist with regard to how men’s and women’s pregnancy desires and intentions are associated with births among contemporary heterosexual couples. There are compelling cultural and structural reasons to support either the hypothesis that men’s desires and intentions (patriarchal) or that women’s desires and intentions (matriarchal) will have more influence, or that both partner’s desires and intentions will be associated with births (mutual influence). In addition, patterns of change are likely to differ for couples that have children at wave 1 compared to those who do not. Path analyses of the of heterosexual couples (n = 615) who completed …

“Caballo”: Risk Environments, Drug Sharing And The Emergence Of A Hepatitis C Virus Epidemic Among People Who Inject Drugs In Puerto Rico, Roberto Abadie, K. Dombrowski

Department of Sociology: Faculty Publications

Background: Sharing drug injection equipment has been associated with the transmission of HCV among PWID through blood contained in the cooker and cotton used to prepare and divide up the drug solution. While epidemiologists often subsume this practice under the sharing of “ancillary equipment,” more attention should be paid to the fact that indirect sharing takes place within the process of joint drug acquisition and preparation.

Methods: We employed an ethnographic approach observing active PWID (N = 33) in four rural towns in Puerto Rico in order to document drug sharing arrangements involved in “caballo”, as this practice is locally …

Of Water Jars And Women: A Re-Evaluation Of Fountain House Imagery On Late Archaic Black-Figure Hydriai, Christopher Askew

School of Art, Art History, and Design: Theses and Student Creative Work

From approximately 530 to 500 BCE, images of fountain houses became popular subjects on black-figure hydriai produced in or around ancient Athens. These scenes often involve groups of unidentified women gathering around a fountain spout, typically attached to an ornate architectural structure, in order to fill their water jars. Although isolated pottery sherds depicting these scenes have been discovered in Greece, approximately seventy-five of these scenes have been identified on Attic hydriai depicting such scenes were discovered in Etruscan tombs. Past scholarship has categorized these images either as genre scenes, which represent a domestic activity characteristic of everyday life, or …

The Kaiparowits Puebloans: Kayentan Or Virgin Branch Migrants?, Phil R. Geib

Department of Anthropology: Faculty Publications

More than 50 years ago archaeologists identified a high-density of small Puebloan habitations on the Kaiparowits Plateau in southern Utah. Analysis of pottery from these habitations by James Gunnerson and Florence Lister resulted in conflicting interpretations of cultural affiliation. Gunnerson argued for a Virgin affiliation whereas Lister argued for a Kayentan affiliation. Lister’s interpretation triumphed and the Puebloan occupation of the Kaiparowits was attributed to a migration of Kayenta people from the south during the late Pueblo II period. A review of architectural and artifactual evidence fails to support a Kayentan migration. An expansion of Puebloan groups from the west …

Cultural Heritage And Local Ecological Knowledge Under Threat: Two Caribbean Examples From Barbuda And Puerto Rico, Rebecca Boger, Sophia Perdikaris, Isabel Rivero-Collazo

School of Global Integrative Studies: Faculty Publications

While the impacts to the infrastructures in Barbuda and Puerto Rico by Hurricanes Irma and Maria have received attention in the news media, less has been reported about the impacts of these catastrophic events on the tangible and intangible cultural heritage of these Caribbean islands. This report provides an assessment of the impacts on the cultural heritage by these storms; tangible heritage includes historic buildings, museums, monuments, documents and other artifacts and intangible heritage includes traditional artistry, festivities, and more frequent activities such as religious services and laundering. While the physical destruction was massive, the social contexts in which these …
