Efforts to conserve stream and river biota could benefit from tools that allow managers to evaluate landscape-scale changes in species distributions in response to water management decisions. We present a framework and methods for integrating hydrology, geographic context and metapopulation processes to simulate effects of changes in streamflow on fish occupancy dynamics across a landscape of interconnected stream segments. We illustrate this approach using a 482 km² catchment in the southeastern US supporting 50 or more stream fish species. A spatially distributed, deterministic and physically based hydrologic model is used to simulate daily streamflow for sub-basins composing the catchment. …

Stochastic And Deterministic Processes Regulate Spatio-Temporal Variation In Seed Bank Diversity, Alejandro A. Royo, Todd E. Ristau

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

Question: Seed banks often serve as reservoirs of taxonomic and genetic diversity that buffer plant populations and influence post-disturbance vegetation trajectories; yet evaluating their importance requires understanding how their composition varies within and across spatial and temporal scales (α- and β-diversity). Shifts in seed bank diversity are strongly governed by the deterministic role of differential seed longevities. Nevertheless, spatio-temporal variability in propagule depletion from and recruitment into seed banks may alter both α- and β-diversity. Here, we ask to what degree deterministic seed exhaustion, stochasticity in recruitment and mortality, or both, shape α- and β-diversity?

Adaptive Divergence At The Margin Of An Invaded Range, Francis F. Kilkenny, Laura F. Galloway

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

Invasive plant species threaten biological communities globally. However, relatively little is known about how evolutionary processes vary over the course of an invasion. To evaluate the importance of historical and adaptive drivers of range expansion, we compare the performance of North American populations of invasive Lonicera japonica from areas established 100–150 years ago, now the southern core of the range, to populations from the northern range margin, established within the last 65 years. Growth and survival of individuals from 17 core and 14 margin populations were compared in common gardens at both regions. After three years, margin plants were larger …

Insights From A Synthesis Of Old And New Climate-Proxy Data From The Pyramid And Winnemucca Lake Basins For The Period 48 To 11.5 Cal Ka, Larry Benson, J.P. Smoot, S.P. Lund, S.A. Mensing, F.F. Foit Jr., R.O. Rye

United States Geological Survey: Staff Publications

A synthesis of old and new paleoclimatic data from the Pyramid and Winnemucca lake basins indicates that, between 48.0 and 11.5∙10³ calibrated years BP (hereafter ka), the climate of the western Great Basin was, to a degree, linked with the climate of the North Atlantic. Paleomagnetic secular variation (PSV) records from Pyramid Lake core PLC08-1 were tied to the GISP2 ice-core record via PSV matches to North Atlantic sediment cores whose isotopic and(or) carbonate records could be linked to the GISP2δ¹⁸O record. Relatively dry intervals in the western Great Basin were associated with cold Heinrich events and …

Masculinity In Comparative Black Literatures, Latoya Renee Jefferson

Electronic Theses and Dissertations

This project examines the ways in which Black men in Africa and throughout the African Diaspora define themselves as gendered beings in their fiction and drama beginning with Richard Wright's publication of Native Son in 1940 to Mariama Ba's So Long a Letter published 1980. Black men created a transnational dialectic concerning their masculinity which involved the creation and criticism of several types of masculinity. In Chapters 1 and 2, I discuss the theoretical and the historical framework for this project. In Chapter 3, I discuss the first type of Black masculinity which was based in opposition to Euro-American stereotypes …

Cracker Barrel's Culture: Exporting The South On America's Interstate Exits, Susan Nicola Penman

Electronic Theses and Dissertations

Cracker Barrel Old Country Store® is a chain restaurant and gift shop with its origins in the South. Formed in 1969 in Lebanon, Tennessee, its success story is one that has much to do with how the company has decided to market and advertise itself along regional lines. This thesis explores the regional elements in Cracker Barrel's language, products, and reputation. It focuses on the company's geographic origins, its history and company lore, and the impact of imitating a historically segregated space (the "old country store"). In addition to that, an integral part of this thesis is the role of …

Two Trains Running: Capture And Escape In The Racialized Train Cars Of The Jim Crow South, 1893-1930, Raleigh Mixon Robinson

Electronic Theses and Dissertations

The role of the railroad in the modern American experience—and its role in making that experience modern—cannot be overstated. This thesis proposes to tell one of many possible railroad stories. By focusing on the historical and cultural relevance of a series of bodies in transit, I examine the implementation of railroad segregation law and the response by African-American performers. The thesis begins at the end of the nineteenth century with the Homer Plessy test case and continues across three decades, meeting along the way novelists Charles Chesnutt and James Weldon Johnson and musicians W. C. Handy, Henry "Ragtime Texas" Thomas, …

Perfect Harmony: The Myth Of Tupelo's Industrial Tranquility, Wendy D. Smith

Electronic Theses and Dissertations

Despite a vast amount of research on Southern labor in the 1930s, historians paid little attention to Northeast Mississippi. This predominantly rural area, though, boasted some of the largest garment factories of the period. Local businessmen established a cotton mill and three clothing manufacturing companies in Tupelo, the seat of Lee County. Town boosters boasted of harmonious relations between workers and management at each of the industrial facilities. In the spring of 1937, however, the cotton mill hands undertook a sit-down strike. Five days later, the women in the Tupelo Garment Company tried to initiate a strike. Both efforts failed. …

A Profession, If You Can Keep It: How Information Technology And Fading Borders Are Reshaping The Law Marketplace And What We Should Do About It, Stephen Gillers

Faculty Articles

Technology is changing the way we do business. It has made cross-border trade in goods and services easy. Capital is finding ways to profit from the law business. Lawyers strive to serve clients wherever they need help, including outside their jurisdiction of admission. These changes not only affect how American law firms work, they challenge our system for licensing and regulating lawyers. The traditional geocentric model for regulating the bar, based on physical place of practice, is unstable today because lawyers can practice physically in many places and (virtually) in every place, yet no place in particular. The next twenty …

The Alternative Staffing Work Experience: Populations, Barriers And Employment Outcomes, Helen Levine, Brandynn Holgate, Risa Takenaka, Françoise Carré

Center for Social Policy Publications

This paper presents results of a three-year study of workers and former workers at four Alternative Staffing Organizations (ASOs). ASOs are fee-for-service job brokering businesses created by community-based organizations and national nonprofits whose objective is to gain access to temporary and “temp to permanent” opportunities for workers facing barriers to employment. The paper looks specifically at the relationship between the personal characteristics of workers, their temporary work experiences through the ASO, and the subsequent employment status of former ASO workers, determined through a follow-up survey conducted by telephone six to eight months after workers had left the ASO. We found …

Brief 3: Clustering Assessment: Enhancing Synergies Among Multilateral Environmental Agreements, Judith Wehrli

Governance and Sustainability Issue Brief Series

Against the background of a widely fragmented and diluted international environmental governance architecture, different reform options are currently being discussed. This issue brief considers whether streamlining international environmental regimes by grouping or ‘clustering’ international agreements could improve effectiveness and efficiency. It outlines the general idea of the clustering approach, draws lessons from the chemicals and waste cluster and examines the implications and potentials of clustering multilateral environmental agreements.

Network Survivability Analysis: Coarse-Graining And Graph-Theoretic Strategies, Teshome Feyessa

Dissertations

Survivability is the ability of a system to continuously deliver essential services despite attacks, failures, or accidents that damage a significant portion of the system. Most of existing survivability measures evaluate global impact of faults on a network by averaging the loss in performance over the whole network. These approaches undermine the fact that a fault is not expected to impact all parts of the network equally. Impacts of some faults are contained in local neighborhoods while others have a global reach. In addition, graph algorithms are often computationally intensive, and even polynomial time algorithms get impractical for a fair …

Measuring Equity In Disability And Healthcare Utilization In Afghanistan, Jean-Francois Trani, Cecile Barbou Des Rosieres

Brown School Faculty Publications

This paper analyses equity in health and healthcare utilization in Afghanistan based on a representative national household survey. Equitable access is a cornerstone of the Afghan health policy. We measured socioeconomic-related equity in access to public health care, using disability– because people with disabilities are poorer and more likely to use health care – and a concentration index (CI) and its decomposition. The socioeconomicrelated equity in healthcare utilization was measured using a probit model and compared with an OLS model providing the horizontal inequity index (HI). We found low rate of healthcare facilities utilization (25%). Disabled persons are using more …

Analyzing The Impact Of County Radon Levels And Population Size On The Allocation Of The State Indoor Radon Grant (Sirg) Funds, Stephen Douglas De Jong

Master's Theses

This thesis examines the SIRG program's effectiveness to target funds to states with the highest risk potential, based on county radon levels and population size. The primary method of determining the program's effectiveness was an analysis of the program's allocation of funds at a regional as well as a state level. The analysis focused on two of four input variables that the EPA utilizes in its regional allocation model (e.g., county radon levels and population size).

The analysis showed that the state-level allocation of funds is only marginally related to a combination of county radon levels and population size, while …

Communication Technology In Disaster Management, Denise Nicole Walker

Wayne State University Theses

ABSTRACT

COMMUNICATION TECHNOLOGY IN DISASTER MANAGEMENT

by DENISE WALKER

This thesis will analyze different case studies involving catastrophic disasters. I will compare their rescue response from the government to FEMA's response to Katrina, to establish a basis for comparison. The Midwest Floods and California fires will be compared to Hurricane Katrina in New Orleans because these places are prone to natural disasters. I will look at each of these states ecology to explain why these states are prone to floods, fires and hurricanes. Unlike the Midwest and California, Hurricane Katrina received far less help from the government and FEMA. I …

Numerical Studies Of Orographic Effects On Tropical Weather Systems, Yi-Chih Huang

Dissertations

With Geophysical Fluid Dynamic Model and Weather Research and Forecasting model, two tropical weather systems, African easterly wave (AEW) and Typhoon Morakot (2009), are studied, respectively. With regards to AEW, wave-like disturbances were generated on the lee side by vortex shedding for an easterly flow over an idealized mountain, with a wavelength of about 2000 km, a period of ~2-3 days, and a propagating speed of ~9.6 ms-1 which mimic an AEW. Thus an AEW may be generated by vortex shedding. Furthermore, these orographically generated hydrostatic, continuously stratified inertia-gravity waves on a β-plane are characterized as mixed Rossby-gravity waves based …

Beyond The Brandopolis: A Communicative Approach To City Promotion And Marketing, Kasey Clawson Hudak

Electronic Theses and Dissertations

A review of current city branding literature indicates that unsuccessful attempts at city branding appear to rely on creating static, flashy, and often idealized images of a city. Such marketing efforts may result in a "brandopolis," or images that may not reflect a city's true identity. This dissertation supplements current city branding literature by exploring how stakeholders' discourses form, enhance, and communicate a city's image. The consideration of a communicative approach to the promotion of city images, from a humanities perspective grounds stakeholders' experiences of the city in their communicative practices. This grounded communicative approach to city marketing offers marketers …

The Effectiveness Of Creating A Sense Of Community In Online Learning With Social Awareness Information, Darren Mariano

Electronic Theses and Dissertations

Online social interactions differ from face to face interactions and lack the non-verbal cues leading a learner to procrastinate, decreased motivation, feelings of isolation and high drop out rates. Existing research illustrates a need for social awareness information in online education, and this research studied the impact of the visual presence of social information on a learner's sense of connectedness and learning using Rovai's (2002) classroom community scale (CCS). Specifically, the study examined if a learners' sense of connectedness is improved with the exposure to others' social awareness information; and if and to what degree learning advanced due to the …

Missing The Trees For The Forest? Learning Environments Versus Learning Techniques In Simulations, Chad Raymond

Faculty and Staff - Articles & Papers

Institutions of higher learning are increasingly asked to defend curricular and pedagogical outcomes. Faculty must demonstrate that simulations are productive tools for learning, but a review of the literature shows that the evidence of their effectiveness is inconclusive, despite their popularity in the classroom. Simulations may in fact help students learn, but the pedagogical benefits of simulations may be being attributed too generally to the learning environments that they supposedly produce, rather than the specific learning modalities that occur within them. The paper concludes with a recommendation that educators choose particular learning techniques first, and then build simulations around these …
