Impact Of Spatial Averaging On Radar Reflectivity At Internal Snowpack Layer Boundaries, N. Rutter, H.P. Marshall, K. Tape, R. Essery, J. King

CGISS Publications and Presentations

Microwave radar amplitude within a snowpack can be strongly influenced by spatial variability of internal layer boundaries. We quantify the impact of spatial averaging of snow stratigraphy and physical snowpack properties on surface scattering from near-nadir frequency-modulated continuous- wave radar at 12–18 GHz. Relative permittivity, density, grain size and stratigraphic boundaries were measured in-situ at high resolution along the length of a 9 m snow trench. An optimal range of horizontal averaging (4–6 m) was identified to attribute variations in surface scattering at layer boundaries to dielectric contrasts estimated from centimetre-scale measurements of snowpack stratigraphy and bulk layer properties. Single …

Assessing Park-And-Ride Efficiency And User Reactions To Parking Management Strategies, Krae E. Stieffenhofer, Michael Barton, Vikash Gayah V.

Journal of Public Transportation

Increasing the number of spaces at overutilized park-and-rides often is not possible due to budgetary and other constraints. Instead, transit agencies may instead seek to maximize the number of people that are able to use the existing spaces through various parking management strategies. Unfortunately, the efficiency of park-and-rides is difficult to measure, so agencies cannot accurately quantify existing use or improvement after parking management strategies have been applied. This study proposed and tested a method to measure the person-efficiency of park-and-ride lots through an onsite audit. Additionally, a user survey was proposed to confirm the audit results and unveil reactions …

Organizational Structure And Class: Examining Resilience In The Maoist Movement In India, Juhi Tyagi

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

What causes armed movements to last? I address this question by taking up the case of the Maoist movement in India. Through an ethnographic analysis and interviews of 127 current cadre, surrendered militants and non-movement village members in 77 villages, over a period of twelve months in 2013-2014 in three districts in Telangana, India, as well creating and analyzing a database on Maoist incidents (2000-2012), I find that non-violent armed group organizing best predicted movement resilience. Although state and political economy variables formed a base for armed rebellion, organizational structures in the villages determined the presence and sustenance of armed …

At The Juncture Of Homonationalism And Homophobic Nationalism: Sexual Justice Organizing In Uganda And The Paradox Of Transnational Advocacy, Sasha Maria Rodriguez

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The Anti-Homosexuality Bill of 2009 propelled Uganda to the forefront of global media. In its initial manifestation, the Bill threatened to penalize “aggravated homosexuality†with the death penalty. The media attention earned by the proposed legislation opened avenues for transnational cooperation and communication between US-based Human and LGBTI Rights organizations and Ugandan kuchus – a Ugandan identity that encapsulates various identities of same gender loving or gender nonconforming peoples. This project focuses on this transnational relationship as it interacts with the dynamic of organizing in the midst of a national project of sexual repression. This dissertation asks how kuchu organizing …

An Analysis Of Morphometric Differentiation In Lake And River Populations Of The Emerald Shiner, Notropis Atherinoides, John J.V. Lang

Biology Theses

Understanding mechanisms that account for phenotypic variation has been of interest to biologists since the advent of Darwin’s theory of evolution by natural selection. It is now understood that adaptive divergence is a key driving force of intraspecific differentiation. Further, differences in habitat (e.g., flow regime, prey regime) have been shown to drive adaptive divergence in fish. For instance, fish inhabiting faster flowing water generally exhibit more fusiform bodies than their lake counterparts. Similarly, the partitioning of benthic and pelagic morphs generally results in smaller heads with the latter. This study used geometric shape analysis to assess morphological differences between …

Homogeneity Pursuit In Panel Data Models: Theory And Applications, Peter C.B. Phillips, Liangjun Su, Wuyi Wang

Cowles Foundation Discussion Papers

This paper studies estimation of a panel data model with latent structures where individuals can be classified into different groups where slope parameters are homogeneous within the same group but heterogeneous across groups. To identify the unknown group structure of vector parameters, we design an algorithm called Panel-CARDS which is a systematic extension of the CARDS procedure proposed by Ke, Fan, and Wu (2015) in a cross section framework. The extension addresses the problem of comparing vector coefficients in a panel model for homogeneity and introduces a new concept of controlled classification of multidimensional quantities called the segmentation net. We …

The Spatial Ecology Of The Eastern Box Turtle (Terrapene Carolina Carolina) In A Fragmented Landscape In Southeast Tennessee, Hamilton County, Mark Dillard

Masters Theses and Doctoral Dissertations

The landscape throughout the range of the Eastern Box turtle (Terrapene carolina carolina) has been altered significantly since the late 1880s by habitat fragmentation. In this study, the spatial ecology and seasonal movement patterns of the Eastern Box turtle in contrasting habitat types are investigated. Eastern Box turtles had home ranges that averaged (mean = 3.77 ± 2.82 ha, minimum convex polygon) in size among individuals. There was no significant difference between mean annual home range size and movement patterns between males and females; however, home range size for male turtles was larger during the summer versus spring activity season …

Measuring Community Adaptive And Transformative Capacity In The Arctic Context, Matthew Berman, Gary Kofinas, Shauna Burnsilver

ISER Articles

Adaptive capacity (AC) plays a prominent role in reducing community vulnerability, an essential goal for achieving sustainability. The related concept, transformative capacity (TC), describes a set of tools from the resilience paradigm for making more fundamental system changes. While the literature appears to agree generally on the meaning of AC and TC, operational definitions vary widely in empirical applications. We address measurement of AC and TC in empirical studies of community vulnerability and resilience, with special attention to the problems of arctic communities. We discuss how some challenges follow from ambiguities in the broader vulnerability model within which AC is …

A Marine Reservoir Effect ∆R Value For Kitandach, In Prince Rupert Harbour, British Columbia, Canada, Kevan Edinborough, Andrew Martindale, Gordon T. Cook, Kisha Supernant, Kenneth M. Ames

Anthropology Faculty Publications and Presentations

Prince Rupert Harbour (PRH), on the north Pacific Coast of British Columbia, contains at least 157 shell middens, of which 66 are known villages, in an area of approximately 180 km2. These sites span the last 9500 yr and in some cases are immense, exceeding 20,000 m2 surface area and several meters in depth. Recent archaeological research in PRH has become increasingly reliant on radiocarbon dates from marine shell for developing chronologies. However, this is problematic as the local marine reservoir effect (MRE) remains poorly understood in the region. To account for the MRE and to better date the Harbour’s …

The resulting phase offset from changes in optical path length due to reflection through snow are the primary measurements made. The research uses data from a field campaign in Fraser, CO, involving an instrument …

Modeling Relative Habitat Suitability And Movement Behavior Of Invasive Burmese Pythons In Southern Florida, Holly E. Mutascio

Open Access Theses

Invasive Burmese pythons are established in the Everglades and are altering the ecology of southern Florida. Their distribution in Florida is expanding northward into more urbanized and fragmented habitats. An understanding of the suitability of habitat throughout southern Florida for Burmese pythons and their interaction with Florida’s landscapes through movement behavior is vital for predicting the python’s ability to persist in habitats outside of the Everglades. In this thesis, we use ecological modeling to predict habitat suitability and to investigate personality-dependent dispersal.

First, we used presence-only ecological niche modeling with correction for sampling bias to identify the key landscape variables …

Investigations On The Vampire Moth Genus Calyptra Ochsenheimer, Incorporating Taxonomy, Life History, And Bioinformatics (Lepidoptera: Erebidae: Calpinae), Julia L. Snyder

Open Access Theses

The seventeen species and two subspecies described in the genus Calyptra are known to be obligate fruit piercers, with some species being of economic importance. Males within the genus have not only been observed piercing their fruit hosts, but have also been documented to occasionally feed on mammalian blood. The genetic and ecological mechanisms contributing to host preference for either plant or vertebrate hosts in this lineage are unknown. Thus, the focus of this study was to investigate the chemosensory systems between and among Calyptra species exhibiting differential feeding strategies. Before investigating the chemosensory systems within Calyptra, the taxonomy …

The Influence Of Alkalinity Of Portland Cement On The Absorption Characteristics Of Superabsorbent Polymers (Sap) For Use In Internally Cured Concrete, Juan D. Tabares Tamayo

Open Access Theses

The concrete industry increasingly emphasizes advances in novel materials that promote construction of more resilient infrastructure. Due to its potential to improve concrete durability, internal curing (IC) of concrete by means of superabsorbent polymers (SAP) has been identified as one of the most promising technologies of the 21st century. The addition of superabsorbent polymers into a cementitious system promotes further hydration of cement by providing internal moisture during the hardening and strength development periods, and thus limits self-desiccation, shrinkage, and cracking.

This thesis presents the work performed on the series of cement pastes with varying alkalinity of their pore solutions …

Mean Hydroclimatic And Hydrological Conditions During Two Climatic Modes In The Devils Lake Basin, North Dakota (Usa), Paul E. Todhunter

Geography & Geographic Information Science Faculty Publications

Proxy variables from palaeolimnological studies of lakes in the Prairie Pothole Region of North America have been used to infer large oscillations during the late Holocene between longer periods of high-salinity–dry conditions and shorter periods of low-salinity–wet conditions producing a normative pattern marked by the absence of hydrological stability. Studies of the historical rise in lake level at Devils Lake have identified 1980 as a transition point between two such hydroclimatic modes. This study uses multiple datasets to characterize the mean hydroclimatological and hydrological conditions of these two climatic modes. Mode 1 is a cool and dry phase, and mode …

State Judicial Selection Methods As Public Policy: The Missouri Plan, James A. Gleason

Open Access Dissertations

State judiciaries are foundational institutions of governance in the United States. They are coequal, policy-making branches of government whose members, along with the legislative and executive branches, are constitutionally authorized and empowered in all fifty American states. Extant research on judicial selection in the American states provides neither a comprehensive theory of why states choose their particular judicial selection method nor a comprehensive empirical assessment of this important question. This research seeks to fill this lacuna by increasing understanding of American state courts through the formulation of a theory of state judicial selection, a short but comprehensive history of state …

Open Access Dissertations

Palmer amaranth is a pernicious summer annual weed that has evolved resistance to six herbicide sites of action in the U.S. and threatens agriculture production. In 2011, Palmer amaranth was identified in flood plains in two southern Indiana counties (Posey and Vanderburgh). Determining if Palmer amaranth can survive and reproduce in northern Indiana may provide insight if this weed will be problematic for northern row crop producers. The objectives of our research were to identify fields containing Palmer amaranth and determine the distribution of herbicide resistance traits in Indiana; determine the influence of tillage frequency and tillage intervals on Palmer …

An Examination Of Geographic Patterns Of Soil Climate And Its Classification In The U.S. System Of Soil Taxonomy, Hans Edwin Winzeler

Open Access Dissertations

Soil climate, the record of temporal patterns of soil moisture and temperature, is an important component of the structure of U.S. Soil Taxonomy. The U.S. Soil Survey has used the Newhall Simulation Model (NSM) for estimating soil climate from atmospheric climate records at weather stations since the 1970s. The current soil climate map of the U.S. was published in 1994 by using NSM runs from selected weather stations along with knowledge-based hand-drawn mapping procedures. We developed a revised soil climate mapping methodology using the NSM and digital soil mapping techniques.

The new methodology is called Grid Element Newhall Simulation Model …

Marine Ecoregion And Deepwater Horizon Oil Spill Affect Recruitment And Population Structure Of A Salt Marsh Snail, Steven C. Pennings, Scott Zengel, Jacob Oehrig, Merryl Alber, T. Dale Bishop, Donald R. Deis, Donna Devlin, A. Randall Hughes, John J. Hutchens, Whitney M. Kiehn, Caroline R. Mcfarlin, Clay L. Montague, Sean Powers, C. Edward Proffitt, Nicolle Rutherford, Camille L. Stagg, Keith Walters

Biology

Marine species with planktonic larvae often have high spatial and temporal variation in recruitment that leads to subsequent variation in the ecology of benthic adults. Using a combination of published and unpublished data, we compared the population structure of the salt marsh snail, Littoraria irrorata, between the South Atlantic Bight and the Gulf Coast of the United States to infer geographic differences in recruitment and to test the hypothesis that the Deepwater Horizon oil spill led to widespread recruitment failure of L. irrorata in Louisiana in 2010. Size-frequency distributions in both ecoregions were bimodal, with troughs in the distributions consistent …
