The 2016 presidential election was a jarring event for polling in the United States. Preelection polls fueled high-profile predictions that Hillary Clinton’s likelihood of winning the presidency was about 90 percent, with estimates ranging from 71 to over 99 percent. When Donald Trump was declared the winner of the presidency, there was a widespread perception that the polls failed. But did the polls fail? And if so, why? Those are among the central questions addressed by an American Association for Public Opinion Research (AAPOR) ad hoc committee. This paper presents the committee’s analysis of the performance of preelection polls in …

Strategic Excellence In Post-Digital Ecosystems: A B2c Perspective, Edin Güçlü Sözer, Mustafa Emre Civelek, Murat Çemberci

Zea E-Books Collection

The basic production of the digital economy is knowledge. As it becomes more important, traditional factors like labor and capital become less so. As technological innovation changes the nature of employment, the conversion of labor to consumption becomes increasingly difficult. E-commerce is the most important driving force of the digital economy. Using technology and information networks effectively allows brands or companies to effect rapid changes in competitive markets. The emergence of neo-consumers calls for a higher order of information exchange and interaction. Companies must reasses their complete business processes in a holistic way to ensure market prominence in an economy …

Evaluation Of Acoustic Telemetry Grids For Determining Aquatic Animal Movement And Survival, Richard T. Kraus, Christopher M. Holbrook, Christopher S. Vandergoot, Taylor R, Stewart, Matthew D. Faust, Douglas A. Watkinson, Colin Charles, Mark A. Pegg, Eva C. Enders, Charles C. Krueger

1. Acoustic telemetry studies have frequently prioritized linear configurations of hydrophone receivers, such as perpendicular from shorelines or across rivers, to detect the presence of tagged aquatic animals. This approach introduces unknown bias when receivers are stationed for convenience at geographic bottlenecks (e.g. at the mouth of an embayment or between islands) as opposed to deployments following a statistical sampling design.

2. We evaluated two-dimensional acoustic receiver arrays (grids: receivers spread uniformly across space) as an alternative approach to provide estimates of survival, movement and habitat use. Performance of variably spaced receiver grids (5–25 km spacing) was evaluated by simulating …

Variability Of Rainfall Erosivity And Erosivity Density In The Ganjiang River Catchment, China: Characteristics And Influences Of Climate Change, Xianghu Li, Xuchun Ye

School of Natural Resources: Faculty Publications

Soil erosion is one of the most critical environmental hazards in the world. Understanding the changes in rainfall erosivity (RE) and erosivity density (ED), as well as their affecting factors, at local and catchment scales in the context of climate warming is an important prerequisite of soil erosion prevention and soil loss risk assessment. The present study identified the variability and trends of RE and ED in terms of both time and space in the Ganjiang River catchment over the period of 1960–2012, and also analyzed and discussed the impact of climate change. The results show that RE and ED …

Population Genomic Analysis Of North American Eastern Wolves (Canis Lycaon) Supports Their Conservation Priority Status, Elizabeth Heppenheimer, Ryan J. Harrigan, Linda Y. Rutledge, Klaus-Peter Koepfli, Alexandra L. Decandia, Kristin E. Brzeski, John F. Benson, Tyler Wheeldon, Brent R. Patterson, Roland Kays, Paul A. Hohenlohe, Bridgett M. Von Holdt

The threatened eastern wolf is found predominantly in protected areas of central Ontario and has an evolutionary history obscured by interbreeding with coyotes and gray wolves, which challenges its conservation status and subsequent management. Here, we used a population genomics approach to uncover spatial patterns of variation in 281 canids in central Ontario and the Great Lakes region. This represents the first genome-wide single nucleotide polymorphism (SNP) dataset with substantial sample sizes of representative populations. Although they comprise their own genetic cluster, we found evidence of eastern wolf dispersal outside of the boundaries of protected areas, in that the frequency …

Ecological Drought: Accounting For The Non-Human Impacts Of Water Shortage In The Upper Missouri Headwaters Basin, Montana, Usa, Jamie Mcevoy, Deborah J. Bathke, Nina Burkardt, Amanda E. Cravens, Tonya Haigh, Kimberly R. Hall, Michael J. Hayes, Theresa Jedd, Marketa Podebradska, Elliot Wickham

School of Natural Resources: Faculty Publications

Water laws and drought plans are used to prioritize and allocate scarce water resources. Both have historically been human-centric, failing to account for non-human water needs. In this paper, we examine the development of instream flow legislation and the evolution of drought planning to highlight the growing concern for the non-human impacts of water scarcity. Utilizing a new framework for ecological drought, we analyzed five watershed-scale drought plans in southwestern Montana, USA to understand if, and how, the ecological impacts of drought are currently being assessed. We found that while these plans do account for some ecological impacts, it is …

Exploring The Role Of Relational Practices In Water Governance Using A Game-Based Approach, Piotr Magnuszewski, Karolina Krolikowska, Anna Koch, Michal Pajak, Craig R.

The growing complexity and interdependence of water management processes requires the involvement of multiple stakeholders in water governance. Multi-party collaboration is increasingly vital at both the strategy development and implementation levels. Multi-party collaboration involves a process of joint decision-making among key stakeholders in a problem domain directed towards the future of that domain. However, the common goal is not present from the beginning; rather, the common goal emerges during the process of collaboration. Unfortunately, when the conflicting interests of different actors are at stake, the large majority of environmental multi-party efforts often do not reliably deliver sustainable improvements to policy …

Validation Of A Process-Based Agro-Ecosystem Model (Agro-Ibis) For Maize In Xinjiang, Northwest China, Tureniguli Amuti, Geping Luo, Gang Yin, Qi Hu, Elizabeth A. Walter-Shea

School of Natural Resources: Faculty Publications

Agricultural oasis expansion and intensive management practices have occurred in arid and semiarid regions of China during the last few decades. Accordingly, regional carbon and water budgets have been profoundly impacted by agroecosystems in these regions. Therefore, study on the methods used to accurately estimate energy, water, and carbon exchanges is becoming increasingly important. Process-based models can represent the complex processes between land and atmosphere among agricultural ecosystems. However, before the models can be applied they must be validated under different environmental and climatic conditions. In this study, a process-based agricultural ecosystem model (Agro-IBIS) was validated for maize crops using …

Enhancing Quantitative Approaches For Assessing Community Resilience, W. C. Chuang, A. Garmestani, T. N. Eason, T. L. Spanbauer, H. B. Fried-Peterson, C. P. Roberts, S. M. Sundstrom, J. L. Burnett, D. G. Angeler, B. C. Chaffin, L. Gunderson, D. Twidwell, C. R. Allen

Scholars from many different intellectual disciplines have attempted to measure, estimate, or quantify resilience. However, there is growing concern that lack of clarity on the operationalization of the concept will limit its application. In this paper, we discuss the theory, research development and quantitative approaches in ecological and community resilience. Upon noting the lack of methods that quantify the complexities of the linked human and natural aspects of community resilience, we identify several promising approaches within the ecological resilience tradition that may be useful in filling these gaps. Further, we discuss the challenges for consolidating these approaches into a more …

Fictive Kinships And The Remaking Of Family Life In The Context Of Paid Domestic Work: The Case Of Philippine Yayas, Maria Rosario De Guzman, Aileen S. Garcia, Minerva D. Tuliao

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

In this chapter, we draw from our study on Filipina rural-to-urban migrant workers in the domestic care sector to illustrate how migrants make and remake family in the context of separation. The setting of our study is in Quezon City, Philippines, and our participants are women employed as yayas-domestic care workers employed to care for children. They live in their employers' homes, and most of our respondents live apart from their own children and all are living away from their nuclear families. Details of this study are laid out in an earlier paper that focused on the experience of family …

From Icon Of Empire To National Emblem: New Evidence For The Fallow Deer Of Barbuda, Sophia Perdikaris, Allison Bain, Sandrine Grouard, Karis Baker, Edith Gonzalez, A. Rus Hoelzel, Holly Miller, Reaksha Persaud, Naomi Sykes

School of Global Integrative Studies: Faculty Publications

Barbuda and Antigua’s national animal is the fallow deer, Dama dama dama, a species native to the eastern Mediterranean that has been transported around the world by people during the last 8000 years. The timing and circumstances by which fallow deer came to be established on Barbuda are currently uncertain but, by examining documentary, osteological and genetic evidence, this paper will consider the validity of existing theories. It will review the dynamics of human–Dama relationships from the 1500s AD to the present day and consider how the meaning attached to this species has changed through time: from a …

On-Road Emissions Of Ammonia: An Underappreciated Source Of Atmospheric Nitrogen Deposition, Mark E. Fenn, Andrzej Bytnerowicz, Susan L. Schilling, Dena M. Vallano, Erika S. Zavaleta, Stuart B. Weiss, Connor Morozumi, Linda H. Geiser, Kenneth Hanks

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

We provide updated spatial distribution and inventory data for on-road NH₃ emissions for the continental United States (U.S.) On-road NH₃ emissions were determined from on-road CO₂ emissions data and empirical NH₃:CO₂ vehicle emissions ratios. Emissions of NH₃ from on-road sources in urbanized regions are typically 0.1– 1.3 t km⁻² yr⁻¹ while NH₃ emissions in agricultural regions generally range from 0.4–5.5 t km⁻² yr⁻¹, with a few hot spots as high as 5.5–11.2 t km⁻² yr⁻¹. Counties with higher vehicle NH3 emissions than from agriculture …

Landscape Transformation During Ceramic Age And Colonial Occupations Of Barbuda, West Indies, Allison Bain, Anne-Marie Faucher, Lisa M. Kennedy, Allison R. Leblanc, Michael J. Burn, Rebecca Boger, Sophia Perdikaris

School of Global Integrative Studies: Faculty Publications

This research documented the history of landscape transformation on the island of Barbuda in the Lesser Antilles, Caribbean through cross-disciplinary research approaches. Excavations confirmed a human presence for the seasonal exploitation of conch meat and other mollusks during the Archaic Age (c.3000–500 BC), but more substantial impacts to terrestrial ecosystems likely began during the Ceramic Age (c.500 BC–AD 1500). Our combined sedimentary and charcoal records revealed that human-induced environmental transformations began with Ceramic Age peoples as they cleared vegetation for settlements and gardens with intentional burning. Sedimentary charcoal indicated a dramatic decline in fire during post-Ceramic Age abandonment, continuing through …

Constructing Rock Cairns: Modifying And Signifying The Alpine Landscape Of Southeast Alaska, Ralph J. Hartley, Amanda Renner, William J. Hunt Jr.

Department of Anthropology: Faculty Publications

The existence and variability of human-made rock cairns in subalpine and alpine settings of Southeast Alaska is increasingly well documented. Whete these features were constructed prehistorically and prorohistorically is a fundamental component to assessing the socioecological role of these modifications to a landscape that is, for the most patt, devoid of other physical manifestations of past human activities. Based on information compiled from investigations in the northern portion of Baranof Island and vicinity, we explore the physical and social environmental conditions that may underlie decisions to create the cairns, some of which are estimated to have been built approximately 500 …

Assessing Hazard Vulnerability, Habitat Conservation, And Restoration For The Enhancement Ofmainland China’S Coastal Resilience, Muhammad Sajjad, Yangfan Li, Zhenghong Tang, Ling Cao, Xiaoping Liu

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

Worldwide, humans are facing high risks from natural hazards, especially in coastal regions with high population densities. Rising sea levels due to global warming are making coastal communities’ infrastructure vulnerable to natural disasters. The present study aims to provide a coupling approach of vulnerability and resilience through restoration and conservation of lost or degraded coastal natural habitats to reclamation under different climate change scenarios. The integrated valuation of ecosystems and tradeoffs model is used to assess the current and future vulnerability of coastal communities. The model employed is based on seven different biogeophysical variables to calculate a natural hazard index …

The Flathead Catfish Invasion Of The Great Lakes, Pam L. Fuller, Gary E. Whelan

United States Geological Survey: Staff Publications

A detailed review of historical literature andmuseumdata revealed that flathead catfish were not historically native in the Great Lakes Basin, with the possible exception of a relict population in Lake Erie. The species has invaded Lake Erie, Lake St. Clair, Lake Huron, nearly all drainages in Michigan, and the Fox/Wolf and Milwaukee drainages in Wisconsin. They have not been collected from Lake Superior yet, and the temperature suitability of that lake is questionable. Flathead catfish have been stocked sparingly in the Great Lakes and is not the mechanism responsible for their spread. A stocking in 1968 in Ohio may be …

South Korean Nationalism And The Legacy Of Park Chung Hee: How Nationalism Shaped Park’S Agendas And The Future Korean Sociopolitical Landscape, Brandon L. Santos

Chadron State Graduate Theses

Park Chung Hee (presidential term: 1961-1979) is, arguably, the most significant leader in the Korean Peninsula’s modern history. His governance has many trademark elements that have been thoroughly analyzed. These include his economic plans and violent dealings against his political opposition. One often overlooked variable, however, is the significant traces of early Korean nationalism (1890s-1930s) that defined his regime. Park employed these ideas, although controversial, to completely change a nation that was teetering on the brink of destruction into what is now, one of the most well-known republics in the world – economically, technologically, and culturally. It is important, therefore, …

Chilean Arpilleras: Writing A Visual Culture, R. Darden Bradshaw

Textile Society of America: Symposium Proceedings

This paper highlights a recent inquiry into the contemporary visual culture of the Chilean arpillera from a cross-global perspective. This art form derived from political, social, and economic conditions of the times yet contemporary manifestations do not address these origins. Arpilleras, historically created in the home and sewn by hand, are constructions in which bits of discarded cloth and burlap were used to compose pictorial narratives. The art form arose in Chile during a period of intense political oppression. This manifestation of women’s fiber art has and continues to serve as both seditious and reconstructive forms of visual culture. While …

A Virgin Martyr In Indigenous Garb? A Curious Case Of Andean Ancestry And Memorial Rites Recalled On A Christian Body, Gaby Greenlee

Textile Society of America: Symposium Proceedings

The notion of “social fabric” has deep resonance in the Andes, where woven textiles have long been entwined with gestures of political alliance, marriage, or rituals marking key transitions in the life cycle. Within the life cycle pre-Conquest, what is more, textiles were heavily implicated in that most poignant of transitions-from life to death. Yet in the Andes, death did not remove one from the life cycle. The deceased remained present and active participants in communal life, seen as potent advocates for the next generation, consulted as oracles, and regularly re-dressed in traditional woven textiles. After the Spanish-Catholic conquest, however, …

Rahul Jain’S Reimagined Velvet Drawloom, Barbara Setsu Pickett

Textile Society of America: Symposium Proceedings

Indian textile traditions are exemplars of Deep Local, firmly rooted in geography and culture. Even family names denote specific occupations; Ansari are weavers; Chippa, block-print dyers; Khatri, bandhani dyers. In the 1980s, two exhibitions introduced me to Indian textiles. The Oregon Museum of Science and Industry’s show, “India Festival of Science included artisans demonstrating their specialties. Ansar Ahmed Ansari, a Varanasi silk brocade weaver, wove sari fabric on a Jacquard loom. After shadowing him for several days, he offered his business card and invited me to visit. In New York at the Met, the India Art and Culture exhibition had …

Looking At The Past And Current Status Of Kenya’S Clothing And Textiles, Mercy V.W. Wanduara

Textile Society of America: Symposium Proceedings

This paper analyzes and documents traditional textiles and clothing of the Kenyan people before and after independence in 1963. The paper is based on desk top research and face to face interviews from senior Kenyan citizens who are familiar with Kenyan traditions. An analysis of some of the available Kenya’s indigenous textile fiber plants is made and from which a textile craft basket is made. Kenya’s textile and clothing industry has undergone tremendous changes from pre-colonial era (before 1963) to date. Traditionally Kenyans donned clothing made out locally available materials; namely plants and animal skin. Color for these materials was …

Common Sense & Pin Money: The Material Culture And Legacy Of Lula Annie Butler 1909-2009, Robin Michel Caudell

Textile Society of America: Symposium Proceedings

“Common Sense and Pin Money: The Material Culture and Legacy of Lula Annie Butler 1909-2009” examines local/global contexts of the late Mrs. Butler’s found quilts, her “make do” ethos, which made a way out of no way decades before recycle, re-purpose and green were hash tags. A lifelong Preston, Maryland resident and domestic worker, Mrs. Butler’s household was outfitted with quilts, tablecloths, aprons, pillows, and shopping bags she created from fabric-sample books and fabric remnants obtained from the late Mrs. Sarah Covey, her longest employer, who operated a drapery and upholstery business in Federalsburg, Maryland. Mrs. Butler’s artistic impulse-vibrant, improvisational, …

Embroidering Paradise: Suzanis As A Place Of Creative Agency And Acculturation For Uzbek Women In 19th Century Bukhara, Shannon Ludington

Textile Society of America: Symposium Proceedings

Central Asian women have long been a point of fascination, written and sung about by others. Exoticized as an oriental “other,” there are many legends but only few historic details known, and then recorded not by themselves but by foreign men. A number of excellent books on women in Uzbekistan under the Soviet Union, and on Uzbek craft and culture in general have been published but most authors conclude there simply is not enough evidence to say anything more about Uzbek women from their own perspective before Soviet times. In Embroidering Paradise: Suzanis as a Place of Creative Agency and …
