Predictors Of Business Return In New Orleans After Hurricane Katrina, Nina S.N. Lam, Helbert Arenas, Kelley Pace, James Lesage, Richard Campanella

Faculty Publications

We analyzed the business reopening process in New Orleans after Hurricane Katrina, which hit the region on August 29, 2005, to better understand what the major predictors were and how their impacts changed through time. A telephone survey of businesses in New Orleans was conducted in October 2007, 26 months after Hurricane Katrina. The data were analyzed using a modified spatial probit regression model to evaluate the importance of each predictor variable through time. The results suggest that the two most important reopening predictors throughout all time periods were the flood depth at the business location and business size as …

The Contact Period Of Central Peten, Guatemala In Color, Timothy W. Pugh, Leslie G. Cecil

Faculty Publications

When Bernal Díaz del Castillo passed by Nojpeten with Hernán Cortés in 1525, he remarked upon the Itza capital’s brilliant whiteness, even from a great distance (Jones 1998:69). However had he stood in the central plaza, he would have discerned that the sun’s reflection eclipsed artifacts and architecture of a variety of colors. The archaeological record is frequently similarly whitewashed by our focus upon form, weight, and distribution. Nevertheless, color helped imbue the Contact period (AD 1525-1697) world of the Maya of the Petén lakes region of Guatemala with significance. This paper investigates the colors of ritual paraphernalia encountered in …

Cry34Ab1/Cry35Ab1 proteins in event DAS-59122-7 and Cry3Bb1 in event MON 88017 were evaluated against the larvae of Mexican corn rootworm, Diabrotica virgifera zeae Krysan and Smith, which occur below-ground. Field corn hybrids containing Cry1F, Cry1A.105 + Cry2Ab2, …

Ecology Of Vibrio Parahaemolyticus And Vibrio Vulnificus In The Coastal And Estuarine Waters Of Louisiana, Maryland, Mississippi, And Washington (United States), Crystal N. Johnson, John C. Bowers, Kimberly J. Griffitt, Vanessa Molina, Rachel W. Clostio, Shaofeng Pei, Edward Laws, Rohinee N. Paranjpye, Mark S. Strom, Arlene Chen, Nur A. Hasan, Anwar Huq, Nicholas F. Noriea Iii, D. Jay Grimes, Rita R. Colwell

Faculty Publications

Vibrio parahaemolyticus and Vibrio vulnificus, which are native to estuaries globally, are agents of seafood-borne or wound infections, both potentially fatal. Like all vibrios autochthonous to coastal regions, their abundance varies with changes in environmental parameters. Sea surface temperature (SST), sea surface height (SSH), and chlorophyll have been shown to be predictors of zooplankton and thus factors linked to vibrio populations. The contribution of salinity, conductivity, turbidity, and dissolved organic carbon to the incidence and distribution of Vibrio spp. has also been reported. Here, a multicoastal, 21-month study was conducted to determine relationships between environmental parameters and V. parahaemolyticus …

[1] The global tropospheric budget of gaseous and particulate non‐methane organic matter (OM) is re‐examined to provide a holistic view of the role that OM plays in transporting the essential nutrients nitrogen and phosphorus to the ocean. A global 3‐dimensional chemistry‐transport model was used to construct the first global picture of atmospheric transport and deposition of the organic nitrogen (ON) and organic phosphorus (OP) that are associated with OM, focusing on the soluble fractions of these nutrients. Model simulations agree with observations within an order of magnitude. Depending on location, the observed water soluble ON fraction ranges from ∼3% to …

Energy Storage Characteristics Of A New Rechargeable Solid Oxide Iron-Air Battery, Xuan Zhao, Nansheng Xu, Xue Li, Yunhui Gong, Kevin Huang

Faculty Publications

Cost effective and large scale energy storage is critical to renewable energy integration and smart-grid energy infrastructure. Rechargeable batteries have great potential to become a class of cost effective technology suited for large scale energy storage. In this paper, we report the energy storage characteristics of a newly developed rechargeable solid oxide iron–air battery. Investigations of the battery’s performance under various current densities and cycle durations show that iron utilization plays a determining role in storage capacity and round-trip efficiency. Further studies of the battery's cycle life reveal a unique charge-cycle originated degradation mechanism that can be interpreted by a …

Inferring The Evolutionary History Of Divergence Despite Gene Flow In A Lizard Species, Scincella Lateralis (Scincidae), Composed Of Cryptic Lineages, Nathan D. Jackson, Christopher C. Austin

Faculty Publications

Although recent radiations are fruitful for studying the process of speciation, they are difficult to characterize and require the use of multiple loci and analytical methods that account for processes such as gene flow and genetic drift. Using multilocus sequence data, we combine hierarchical cluster analysis, coalescent species tree inference, and isolation-with-migration analysis to investigate evolutionary relationships among cryptic lineages of North American ground skinks. We also estimate the extent that gene flow has accompanied or followed diversification, and also attempt to account for and minimize the influence of gene flow when reconstructing relationships. The data best support seven largely …

Fe 2+-and Mn 2+-rich tourmalines were used to test whether Fe 2+ and Mn 2+ substitute on the Z site of tour- maline to a detectable degree. Fe-rich tourmaline from a pegmatite from Lower Austria was characterized by crystal-structure refinement, chemical analyses, and Mössbauer and optical spectroscopy. The sample has large amounts of Fe 2+ (∼2.3 apfu), and substantial amounts of Fe 3+ (∼1.0 apfu). On basis of the collected data, the structural refinement and the spectroscopic data, an initial formula was determined by assigning the entire amount of Fe 3+ (no delocalized electrons) and Ti 4+ to the Z …

Playing Without Aces: Offset And The Limits Of Flexibility Under Clean Air Act Climate Policy, Nathan D. Richardson

Faculty Publications

The United States Environmental Protection Agency (EPA) continues to move ahead with regulation of greenhouse gas emissions under the Clean Air Act (CAA). Previous work has indicated that basic forms of compliance flexibility—trading—appear to be legally permissible under section III of the CAA. This Article takes a close look at more expansive and ambitious types of flexibility: trading between different kinds of sources, biomass co-firing, and above all, offsets. It concludes that most types of such extended flexibility are either legally incompatible with the CAA, or so legally problematic that EPA is unlikely to adopt them. This has important implications …

The collapse of the Bronze Age Harappan, one of the earliest urban civilizations, remains an enigma. Urbanism flourished in the western region of the Indo-Gangetic Plain for approximately 600 y, but since approximately 3,900 y ago, the total settled area and settlement sizes declined, many sites were abandoned, and a significant shift in site numbers and density towards the east is recorded. We report morphologic and chronologic evidence indicating that fluvial landscapes in Harappan territory became remarkably stable during the late Holocene as aridification intensified in the region after approximately 5,000 BP. Upstream on the alluvial plain, the large Himalayan …

Geospatial Examination Of Lithium In Drinking Water And Suicide Mortality, Marco Helbich, Michael Leitner, Nestor D. Kapusta

Sub-Pixel Classification Of Forest Cover Types In East Texas, Joey Westbrook, I-Kuai Hung, Daniel Unger, Yanli Zhang

Faculty Publications

Sub-pixel classification is the extraction of information about the proportion of individual materials of interest within a pixel. Landcover classification at the sub-pixel scale provides more discrimination than traditional per-pixel multispectral classifiers for pixels where the material of interest is mixed with other materials. It allows for the un-mixing of pixels to show the proportion of each material of interest. The materials of interest for this study are pine, hardwood, mixed forest and non-forest. The goal of this project was to perform a sub-pixel classification, which allows a pixel to have multiple labels, and compare the result to a traditional …

Italy At Home And Abroad After 150 Years: The Legacy Of Emigration And The Future Of Italianità, Mark I. Choate

Faculty Publications

Shortly after unification in the Risorgimento, mass emigration stretched Italy in unforeseen ways, changing its culture, economics, and politics, and even its state, territory, language, and population. This enforced globalization polarized Italy and radically changed Italy as a nation-state and as a national culture. Controversies over emigration sharply divided Italian Liberals from the Nationalists and Fascists. The ideals of the nation-state, articulated by Mazzini, have been transformed by emigration in ways that have anticipated the twenty-first century global world. Today Italy faces similar challenges with rising immigration, together with the potential for constructive solutions.

A Two-Stage Cluster Sampling Method Using Gridded Population Data, A Gis, And Google Earth(Tm) Imagery In A Population-Based Mortality Survey In Iraq, Lp Galway, Nathaniel Bell, Al Shatari Sae, Amy Hagopian, Gilbert Burnham, Abraham Flaxman, Wiliam M. Weiss, Julie Rajaratnam, Tim K. Takaro

Faculty Publications

BACKGROUND:

Mortality estimates can measure and monitor the impacts of conflict on a population, guide humanitarian efforts, and help to better understand the public health impacts of conflict. Vital statistics registration and surveillance systems are rarely functional in conflict settings, posing a challenge of estimating mortality using retrospective population-based surveys.

RESULTS:

We present a two-stage cluster sampling method for application in population-based mortality surveys. The sampling method utilizes gridded population data and a geographic information system (GIS) to select clusters in the first sampling stage and Google Earth TM imagery and sampling grids to select households in the second sampling …

Getting Away With Murder (Most Of The Time): Civil War Era Homicide Cases In Boone County, Missouri, Frank O. Bowman Iii

Faculty Publications

Much of the modem American legal process is dependent, not on particular substantive or procedural rules, but on legal and societal infrastructure that we tend to take for granted. To give the simplest example, appellate practice in Missouri (and elsewhere) was stunted until the late 1880s by the absence of court reporters who could create the verbatim trial records upon which a detailed review for error depends. The study of actual cases decided by juries and judges - law in action, rather than law in theory - owes its fascination to the insights it gives into what people really believe …

School Racial Composition And Race/Ethnic Differences In Early Adulthood Health, Bridget J. Goosby, Katrina M. Walsemann

Faculty Publications

We investigate whether school racial composition is associated with racial and ethnic differences in early adult health. We then examine whether perceived discrimination, social connectedness, and parent support attenuates this relationship. Using U.S. data from Wave I and IV of the National Longitudinal Survey of Adolescent Health, we found that black adolescents attending predominantly white schools reported poorer adult health while Asians reported better health. Further research is warranted to understand whether there are qualitative differences in the treatment of racial and ethnic minorities within certain school contexts and how that differential treatment is related to adult health outcomes.

Artificial Modifications Of The Coast In Response To The Deepwater Horizon Oil Spill: Quick Solutions Or Long-Term Liabilities?, Marisa Luisa Martínez, Rusty A. Feagin, Kevin M.

Faculty Publications

The Deepwater Horizon oil spill threatened many coastal ecosystems in the Gulf of Mexico during the spring and summer of 2010. Mitigation strategies included the construction of barrier sand berms, the restriction or blocking of inlets, and the diversion of freshwater from rivers to the coastal marshes and into the ocean, in order to flush away the oil, on the premise that these measures could reduce the quantity of oil reaching sensitive coastal environments such as wetlands or estuaries. These projects result in changes to the ecosystems that they were intended to protect. Long-term effects include alterations of the hydrological …

The Mapping Of Composite Pollen From Point Sampled Data And Cartographic Generalization, Peter P. Siska, I-Kuai Hung, Vaughn M. Bryant Jr.

Faculty Publications

Pollen grains are microgametophytes produced by angiosperm and gymnosperm plants. They are responsible for transporting genetic material and carrying out fertilization. The study of pollen has numerous practical applications such as plant biodiversity, paleoclimatology, archaeology, allergy studies, the study of nectar sources in honey (melissopalynology), searching for sources of petroleum, and more recently, using pollen as a trace evidence component in forensics. Once pollen grains become airborne, their dispersal is controlled by a number of physical factors that determine the deposition distance from their source area. The purpose of this work is to study spatial pattern of composite pollen in …
