Sustaining Conversations For Rural North Dakota Language Arts Teachers, Erika Joy Dyk

English

This qualitative study explores the role conversation plays in sustaining rural North Dakota Language Arts teachers. This study examines the questions: What conversations are sustained rural North Dakota Language Arts teachers engaging in? and What role does conversation play in sustaining rural North Dakota Language Arts teachers? Six rural Language Arts teachers were interviewed about their experiences with conversation using the framework of the three different discourse communities as proposed by Australian researchers Tytler et al. for rural professional development: the local school community, the local community, and the subject-matter community. Tytler et al.’s framework was productive in this study …

Considering The Effects Of Climate Change On Natural Resources In Environmental Review And Planning Documents: Guidelines For Agencies And Practitioners, Jessica A. Wentz

Sabin Center for Climate Change Law

This paper describes how climate change will affect natural resources in the United States, and explains why consideration of how climate change will affect those resources is necessary in order to fulfill legal requirements under NEPA and other statutes governing the management of these resources. It also presents examples of how climate change has been meaningfully accounted for in environmental review and planning documents. The accompanying protocol contains guidelines for considering the impacts of climate change in environmental reviews as well as other planning documents (e.g., resource management plans and resource assessments).

Federal Implementation Plans And The Path To Clean Power, Daniel Selmi

Sabin Center for Climate Change Law

Promulgated under the Clean Air Act in October 2015, the Clean Power Plan (“CPP”) requires states to significantly reduce carbon emissions from existing power plants and is the centerpiece of the Environmental Protection Agency’s (“EPA”) response to global warming. Many states have filed lawsuits challenging the CPP and some states have vowed that, if those suits are unsuccessful, they will refuse to implement it. In turn, EPA has proposed rules that would implement the CPP by imposing a “federal implementation plan” (“FIP”) upon those recalcitrant states under the authority of the Clean Air Act. Thus, the success of the CPP …

Inclusion, Exclusion, And The "New" Economic Inequality, Olatunde C.A. Johnson

Faculty Scholarship

Is racial inequality an unwelcome intruder to the new discourse on economic inequality? The present discourse on economic inequality emphasizes decades-long trends that have increased economic inequality, whether as a result of reoccurring features in the structure of capitalist economies or more recent changes in institutional, structural, and economic conditions. Researchers direct us to the rising fortunes of the top earners and asset holders relative to the rest, the declining fortunes of the middle class harmed by stagnating wages, and the declining share of industries (like manufacturing) in the economy. This new economic inequality discourse has preoccupied economists, garnered its …

The Importance Of The Artist's Intent, Daniel Conrad

Contemporary Aesthetics (Journal Archive)

Does considering artists' aesthetic intentions enrich our experience of art and enhance art’s aggregate value for human culture? By examining non-aesthetic intent, working motivations, biographical/historical context, and cases in which an announced intent drives aesthetic transformation, I argue that, while its specific value varies from case to case, aesthetic intent is a key part of our cumulative experience of art, correlates with specific neuroanatomical loci, and raises interesting and compelling questions specific to this age of automatized thinking.

Analyzing Winter Migration Fidelity And Movement Of The Wild Taimyr Reindeer Herd, Rangifer T. Tarandus, Emily T. Francis

Dissertations and Theses @ UNI

The Taimyr Reindeer Herd (TRH) is the largest wild reindeer population in the world, and is located in the northern central region of Arctic Russia. Previous detailed research on the spatiotemporal dynamics of this herd have been conducted involving aerial population censuses for two of the three seasons for reindeer: calving (Meerdink, 2012) and summer (Cooney, 2014). The first part of this study continues with the methods of the previous studies, analyzing the spatiotemporal fidelity of the TRH in the winter season. This was completed using geospatial analysis of digitized historical aerial census data of reindeer locations, and analyzing areas …

The Cultural And Rhetorical Elements Of American Picaresque, Cory James Dahlstrom

Dissertations and Theses @ UNI

The picaresque is a literary genre with a long and rich history. Although protean in nature, it is essentially the fictional autobiography of a likeable delinquent or rogue, who survives a series of adventures and a life of hardships by his or her wits and affinity for trickery. Stemming from a long line of tropes dating back to Greek mythology, the picaresque comes into its own fruition towards the end of the Spanish Golden Age with the anonymous publication of Lazarillo de Tormes (1554). Since then, the antihero of the picaresque, the picaro, has become a literary figure across a …

How can capacity for teaching for competency be built and supported through new policies?  How can curricula and pedagogy be better aligned to facilitate the building of sustainability competency in learners and teachers?  What effect …

Ballot-Box Environmentalism Across The Golden State: How Geography Influences California Voters’ Demand For Environmental Public Goods, William Skyler Lewis

Pomona Senior Theses

In California, voters frequently face ballot propositions dealing directly or indirectly with environmental protection. Records of these votes provide powerful evidence of the character of voters’ demand and willingness-to-pay for environmental public goods (e.g., air quality, watershed ecosystem services, parks and recreation), and have been used in past environmental econometrics research to produce aggregated income and price effect estimates. Using neighborhood-level voting records on seven environmental-related ballot propositions in California between 2002 and 2010, this econometric study investigates the nature of voters’ demand for environmental public goods, focusing on the effect of household income on pro-environment voting. Unlike previous studies, …

Public Libraries And Political Participation, 1870-1940, Michael J. Kevane, William A. Sundstrom

Economics

The public library movement of the late 19th and early 20th centuries fostered a rapid increase in the number and quality of public libraries in cities and towns across the United States. One important argument for libraries was that they would enhance American democracy by promoting virtues of citizenship and enabling access to information. This paper examines how voter turnout was affected, in the short-term, by the establishment of public libraries, using a county-by-election year panel. Our empirical strategy exploits the founding dates of public libraries as discrete events that should have influenced subsequent voting behavior. Over the wide range …

A new global synthesis and biomization of long (> 40 kyr) pollen-data records is presented and used with simulations from the HadCM3 and FAMOUS climate models and the BIOME4 vegetation model to analyse the dynamics of the global terrestrial biosphere and carbon storage over the last glacial–interglacial cycle. Simulated biome distributions using BIOME4 driven by HadCM3 and FAMOUS at the global scale over time generally agree well with those inferred from pollen data. Global average areas of grassland and dry shrubland, desert, and tundra biomes show large-scale increases during the Last Glacial Maximum, between ca. 64 and 74 ka BP …

Inferring Late-Holocene Climate In The Ecuadorian Andes Using A Chironomid-Based Temperature Inference Model, Frazer Matthews-Bird, Stephen J. Brooks, Philip B. Holden, Encarni Montoya, William D. Gosling

Ocean Engineering and Marine Sciences Faculty Publications

Presented here is the first chironomid calibration data set for tropical South America. Surface sediments were collected from 59 lakes across Bolivia (15 lakes), Peru (32 lakes), and Ecuador (12 lakes) between 2004 and 2013 over an altitudinal gradient from 150 m above sea level (a.s.l) to 4655 m a.s.l, between 0–17° S and 64–78° W. The study sites cover a mean annual temperature (MAT) gradient of 25 °C. In total, 55 chironomid taxa were identified in the 59 calibration data set lakes. When used as a single explanatory variable, MAT explains 12.9 % of the variance (λ1/λ2 =  1.431). …

Environmental Controls On The Distribution And Diversity Of Lentic Chironomidae (Insecta: Diptera) Across An Altitudinal Gradient In Tropical South America, Frazer Matthews-Bird, William D. Gosling, Angela L. Coe, Mark Bush, Francis E. Mayle, Yarrow Axford, Stephen J. Brooks

Ocean Engineering and Marine Sciences Faculty Publications

To predict the response of aquatic ecosystems to future global climate change, data on the ecology and distribution of keystone groups in freshwater ecosystems are needed. In contrast to mid- and high-latitude zones, such data are scarce across tropical South America (Neotropics). We present the distribution and diversity of chironomid species using surface sediments of 59 lakes from the Andes to the Amazon (0.1–17°S and 64–78°W) within the Neotropics. We assess the spatial variation in community assemblages and identify the key variables influencing the distributional patterns. The relationships between environmental variables (pH, conductivity, depth, and sediment organic content), climatic data, …

The Wealth Of Subnations: Geography, Institutions, And Within-Country Development, Todd Mitton

Faculty Publications

I study determinants of economic development in a new dataset covering 1867 subnational regions from 101 countries, focusing on within-country effects of geography and institutions. Several geographic factors have significant explanatory power forwithin-country differences in per-capita GDP, including terrain ruggedness, tropical climate, ocean access, temperature range, storm risk, and natural resources such as oil, diamonds, or iron. Institutions have a significant positive effect on income among subnational regions with greater autonomy, suggesting that strong subnational institutions enhance development when not dominated by national institutions.

The Uncoordinated Public Domain, Robert Spoo

Cardozo Arts & Entertainment Law Journal

When nations amend their copyright laws in response to calls for international harmonization, they usually expand authors' rights without also seeking to harmonize national public domains. Divergent national copyright laws have resulted in an uncoordinated global public domain that renders authors' works freely available for use in some countries while subjecting them to copyright or moral-rights protection in others. While the fragmented global commons thwarts many valuable uses of cultural resources, it has especially deleterious effects on the ability of researchers to access, copy, and disseminate historical and literary materials, many of which remain unpublished. These effects are mirrored and …

Radioactive Dixie: A History Of Nuclear Power And Nuclear Waste In The American South, 1950-1990, Caroline Rose Peyton

Theses and Dissertations

“Radioactive Dixie: A History of Nuclear Power and Nuclear Waste in the American South, 1950-1990,” examines the political, social, cultural, economic, environmental, and technological dimensions of the nuclear industry in the American South. Today, the US South contains more nuclear reactors than any other region and much of the nation’s radioactive waste. In “Radioactive Dixie,” I argue that this regional distinction resulted from a decades-long effort by southern politicians, industry figures, and government officials to transform the American South into a nuclear-oriented region. Waving the atomic talisman, the nuclear industry served as one pivotal part in a larger project of …

Neuro-Fuzzy Classification Of Felsic Lava Geomorphology At Alarcon Rise, Mexico, Christina Hefron Maschmeyer

Theses and Dissertations

The Alarcon Rise is the only submarine oceanic spreading ridge setting where rhyolitic lavas have been found. This intermediate-rate spreading ridge provides a unique natural laboratory for studying the geomorphology of felsic submarine lava flows at oceanic spreading ridges. Seafloor observations of felsic lava indicate the flow morphology differs from typical submarine basaltic lava at the few other oceanic spreading ridges where differentiated compositions have been recorded. Morphologic variation between mafic and felsic lava flows, especially rhyolites, was also observed at Alarcon Rise.

The Monterey Bay Aquarium Research Institute conducted mapping surveys with autonomous underwater vehicle D Allan B. in …

Race, Place, And Access To Early Intensive Behavioral Intervention Among Children With Autism Spectrum Disorder In South Carolina, Marissa E. Yingling

Theses and Dissertations

Public funding of early intensive behavioral intervention (EIBI) for the 1 in 68 children who meet criteria for autism spectrum disorder (ASD) is rapidly expanding. Evidence indicates that children with ASD experience racial, socioeconomic, and geographic disparities in access to health care services. However, the Interagency Autism Coordinating Committee and the World Health Organization cite disparities in access to early intervention among the most pressing yet understudied areas of research. Currently, ASD service research is dominated by inquiries into the age of diagnosis and enrollment in EIBI. We know little about disparities in the time-lag between diagnosis and treatment onset …

Gatebe, Jun Wang, Eric M. Wilcox, Jejung Lee, Jimmy Adegoke, Churchill Okonkwo, John Bolten, Frederick S. Policelli, Shahid Habib

Department of Earth and Atmospheric Sciences: Faculty Publications

The Northern Sub-Saharan African (NSSA) region, which accounts for 20%–25%of the global carbon emissions from biomass burning, also suffers from frequent drought episodes and other disruptions to the hydrological cycle whose adverse societal impacts have been widely reported during the last several decades. This paper presents a conceptual framework of the NSSA regional climate system components that may be linked to biomass burning, as well as detailed analyses of a variety of satellite data for 2001–2014 in conjunction with relevant model-assimilated variables. Satellite fire detections in NSSA show that the vast majority (>75%) occurs in the savanna and woody …

Climatology, Synoptic Conditions, And Misanalyses Of Mississippi River Valley Drylines, Rebecca S. Duell, Matthew S. Van Den Broeke

Department of Earth and Atmospheric Sciences: Faculty Publications

The dryline is an important focal point for convection initiation. Although drylines most commonly occur on the southern Great Plains, dryline passages and subsequent severe weather outbreaks have been documented in the Mississippi River valley. This study presents a 15-yr (1999–2013) climatology of these Mississippi River valley drylines and associated severe weather. Additionally, synoptic patterns are identified that may result in drylines moving atypically far eastward into the Mississippi River valley. In total, 39 Mississippi River valley drylines (hereafter referred to as MRV drylines) were identified from the North American Regional Reanalysis (NARR) dataset through the study period. Mean and …

The Impact Of Long-Term Dietary Pattern Of Fecal Donor On In Vitro Fecal Fermentation Properties Of Inulin, Junyi Yang, Devin J. Rose

Department of Food Science and Technology: Faculty Publications

Although the composition of the gut microbiota is of interest, the functionality, or metabolic activity, of the gut microbiota is of equal importance: the gut microbiota can produce either harmful metabolites associated with human disease or beneficial metabolites that protect against disease. The purposes of this study were to determine the associations between dietary intake variables and fecal short and branched chain fatty acid (S/BCFA) concentrations; to determine the associations between dietary intake variables and inulin degradation, short and branched chain fatty acid (S/BCFA) production, and ammonia production during in vitro fecal fermentation of a highly fermentable substrate (inulin); and …

Mobilization And Adaptation Of A Rural Cradle-To-Career Network, Sarah J. Zuckerman

Department of Educational Administration: Faculty Publications

This case study explored the development of a rural cradle-to-career network with a dual focus on the initial mobilization of network members and subsequent adaptations made to maintain mobilization, while meeting local needs. Data sources included interviews with network members, observations of meetings, and documentary evidence. Network-based social capital facilitated mobilization. Where networks were absent and where distrust and different values were evident, mobilization faltered. Three network adaptations were discovered: Special rural community organizing strategies, district-level action planning, and a theory of action focused on out-of-school factors. All three were attributable to the composition of mobilized stakeholders and this network’s …

Johnsongrass (Sorghum halepense) is a striking example of a post-Columbian founder event. This natural experiment within ecological time-scales provides a unique opportunity for understanding patterns of continent-wide genetic diversity following range expansion. Microsatellite markers were used for population genetic analyses including leaf-optimized Neighbor-Joining tree, pairwise FST, mismatch analysis, principle coordinate analysis, Tajima's D, Fu's F and Bayesian clusterings of population structure. Evidence indicates two geographically distant introductions of divergent genotypes, which spread across much of the US ingeophylogeny, gene flow patterns can be inferred to have involved five phases. Centers of genetic diversity have shifted from two introduction …

Is The Relationship Between Mast-Seeding And Weather In Oaks Related To Their Life-History Or Phylogeny?, Walter D. Koenig, Reyes Alejano, Maria Dolores Carbonero, Pilar Fernández-Rebollo, Johannes Knops, Teodoro Marañón, Carmen M. Padilla-Díaz, Ian S. Pearse, Ignacio M. Pérez-Ramos, Javier Vázquez-Piqué, Mario B. Pesendorfer

School of Biological Sciences: Faculty Publications

Although the functional basis of variable and synchronous seed production (masting behavior) has been extensively investigated, only recently has attention been focused on the proximate mechanisms driving this phenomenon. We analyzed the relationship between weather and acorn production in 15 species of oaks (genus Quercus) from three geographic regions on two continents, with the goals of determining the extent to which similar sets of weather factors affect masting behavior across species and to explore the ecological basis for the similarities detected. Lag-1 temporal autocorrelations were predominantly negative, supporting the hypothesis that stored resources play a role in masting behavior …

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Climatic variables not only directly affect the interannual variability (IAV) in net ecosystem exchange of CO2 (NEE) but also indirectly drive it by changing the physiological parameters. Identifying these direct and indirect paths can reveal the underlying mechanisms of carbon (C) dynamics. In this study, we applied a path analysis using flux data from 65 sites to quantify the direct and indirect climatic effects on IAV in NEE and to evaluate the potential relationships among the climatic variables and physiological parameters that represent physiology and phenology of ecosystems. We found that the maximum photosynthetic rate was the most important factor …

Baylisascaris Larva Migrans, Kevin R. Kazacos

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Zoonotic diseases, such as baylisascariasis, are receiving increasing attention as components of disease emergence and resurgence (Kazacos, 2001). Baylisascariasis is caused by the roundworm Baylisascaris procyonis and is one of the more recent zoonotic disease developments. This disease remains one of the least known and poorly understood zoonotic diseases, yet over the past several decades it has become widespread. It originated in wildlife species and is now well established as a human malady. Baylisascariasis is transmitted to humans via consumption of contaminated feces, and the role of wildlife (primarily raccoons) in this transmission process is becoming more clearly known and …

Regional Investigation Of A Cyclosporiasis Outbreak Linked To Imported Romaine Lettuce – Nebraska And Iowa, June–August 2013, Bryan F. Buss, M. V. Joshi, C. D. Allensworth, A. Garvey, K. Obbink, S. Mandernach, Thomas J. Safranek

Department of Food Science and Technology: Faculty Publications

A regional, multistate investigation into a June–August 2013 cyclosporiasis outbreak was conducted in Nebraska, Iowa, and neighbouring states. Cases were confirmed on the basis of laboratory and clinical findings. Of 227 cases in Iowa (n = 140) and Nebraska (n=87) residents, 162 (71%) reported dining at chain A/B restaurants – 96% reported house salad consumption. A case-control study identified chain A/B house salad as the most likely vehicle. Traceback was conducted to ascertain production lot codes of bagged salad mix (iceberg and romaine lettuce, red cabbage, and carrots) served as house salad in implicated restaurants. A single production lot code …

Constructing Stability Landscapes To Identify Alternative States In Coupled Social-Ecological Agent-Based Models, Patrick Bitterman, David A. Bennett

Geography Program: Faculty Publications

The resilience of a social-ecological system is measured by its ability to retain core functionality when subjected to perturbation. Resilience is contextually dependent on the state of system components, the complex interactions among these components, and the timing, location, and magnitude of perturbations. The stability landscape concept provides a useful framework for considering resilience within the specified context of a particular social-ecological system but has proven difficult to operationalize. This difficulty stems largely from the complex, multidimensional nature of the systems of interest and uncertainty in system response. Agent-based models are an effective methodology for understanding how cross-scale processes within …
