Academic Writing And Theological Inquiry, Terry Dwain Robertson

Faculty Publications

A comparison of two approaches to academic writing and research pedagogies demonstrates that, for Vyhmeister, truth is to be found outside and above us--it is a process of discovery, while Hamilton's approach focuses on the spiritual formation of the writer and can be understood as reflecting a process of spiritual growth. A third approach, which I develop in this article, views academic writing and theological inquiry as a ministry, in which the writer is served by and, in turn, serves the community of faith for the purpose of building a corporate knowledge of God. Research is service and the dissemination …

Biogeography And The Cambrian Radiation Of Arachnomorph Arthropods, Jonathan R. Hendricks, Bruce S. Lieberman

Faculty Publications

Biogeographic patterns in primarily Cambrian arachnomorph taxa are investigated using a recently constructed phylogenetic hypothesis in order to explore the biogeographic context of the Cambrian radiation. A modified version of Brooks Parsimony Analysis is employed to elucidate patterns of vicariance and geodispersal in taxa from six regions (Laurentia, Baltica, Siberia, Australia, Africa and China). Well resolved vicariance and geodispersal trees are very similar and reconstruct Laurentia and China as sister areas. This close area relationship between Laurentia and China provides extensive evidence for congruent vicariance and range expansion in Cambrian arachnomorphs, while data from trilobites do not show this pattern. …

The Large‐Scale Freshwater Cycle Of The Arctic, Mark C. Serreze, Andrew P. Barrett, Andrew G. Slater, Rebecca A. Woodgate, Knut Aagaard, Richard B. Lammers, Michael Steele, Richard Moritz, Michael Meredith, Craig M. Lee

Faculty Publications

This paper synthesizes our understanding of the Arctic's large‐scale freshwater cycle. It combines terrestrial and oceanic observations with insights gained from the ERA‐40 reanalysis and land surface and ice‐ocean models. Annual mean freshwater input to the Arctic Ocean is dominated by river discharge (38%), inflow through Bering Strait (30%), and net precipitation (24%). Total freshwater export from the Arctic Ocean to the North Atlantic is dominated by transports through the Canadian Arctic Archipelago (35%) and via Fram Strait as liquid (26%) and sea ice (25%). All terms are computed relative to a reference salinity of 34.8. Compared to earlier estimates, …

Faculty Publications

The sex pheromone of the scarab beetle, Phyllophaga anxia, is a blend of the methyl esters of two amino acids, L-valine and L-isoleucine. A field trapping study was conducted, deploying different blends of the two compounds at 59 locations in the United States and Canada. More than 57,000 males of 61 Phyllophaga species (Coleoptera: Scarabaeidae: Melolonthinae) were captured and identified. Three major findings included: (1) widespread use of the two compounds [of the 147 Phyllophaga (sensu stricto) species found in the United States and Canada, males of nearly 40% were captured]; (2) in most species intraspecific male response to the …

A Molecular Phylogenetic Analysis Of Strombid Gastropod Morphological Diversity, Jared M. Latiolais, Michael S. Taylor, Kaustuv Roy, Michael E. Hellberg

Faculty Publications

The shells of strombid gastropods show a wide variety of forms, ranging from small and fusiform to large and elaborately ornamented with a strongly flared outer lip. Here, we present the first species-level molecular phylogeny for strombids and use the resulting phylogenetic framework to explore relationships between species richness and morphological diversity. We use portions of one nuclear (325 bp of histone H3) and one mitochondrial (640 bp of cytochrome oxidase I, COI) gene to infer relationships within the two most species-rich genera in the Strombidae: Strombus and Lambis. We include 32 species of Strombus, representing 10 of 11 extant …

Urban Surface Biophysical Descriptors And Land Surface Temperature Variations, Bingqing Liang, Qihao Weng, Dengsheng Lu

Faculty Publications

In remote sensing studies of land surface temperatures (LST), thematic land-use and land-cover (LULC) data are frequently-employed for simple correlation analyses between LULC types and their thermal signatures. Development of quantitative surface descriptors could improve our capabilities for modeling urban thermal landscapes and advance urban climate research. This study developed an analytical procedure based upon a spectral unmixing model for characterizing and quantifying the urban landscape in Indianapolis, Indiana. A Landsat Enhanced Thematic Mapper Plus image of the study area, acquired on 22 June 2002, was spectrally unmixed into four fraction endmembers, namely, green vegetation, soil, high and low albedo. …

Spatial Confidentiality And Gis: Re-Engineering Mortality Locations From Published Maps About Hurricane Katrina, Andrew J. Curtis, Jacqueline W. Mills, Michael Leitner

Faculty Publications

Background: Geographic Information System (GIS) can provide valuable insight into patterns of human activity. Online spatial display applications, such as Google Earth, can democratise this information by disseminating it to the general public. Although this is a generally positive advance for society, there is a legitimate concern involving the disclosure of confidential information through spatial display. Although guidelines exist for aggregated data, little has been written concerning the display of point level information. The concern is that a map containing points representing cases of cancer or an infectious disease, could be re-engineered back to identify an actual residence. This is …

Liana Habitat Associations And Community Structure In A Bornean Lowland Tropical Forest, Saara J. Dewalt, Kalan Ickes, Reuben Nilus, Kyle E. Harms, David F.R.P. Burslem

Faculty Publications

Lianas (woody vines) contribute substantially to the diversity and structure of most tropical forests, yet little is known about the importance of habitat specialization in maintaining tropical liana diversity and the causes of variation among forests in liana abundance and species composition. We examined habitat associations, species diversity, species composition, and community structure of lianas at Sepilok Forest Reserve, Sabah, Malaysia in northeastern Borneo among three soil types that give rise to three distinct forest types of lowland tropical rain forest: alluvial, sandstone hill, and kerangas (heath) forest. Alluvial soils are more nutrient rich and have higher soil moisture than …

Thermochronology Of Mineral Grains In The Red And Mekong Rivers, Vietnam: Provenance And Exhumation Implications For Southeast Asia, Peter D. Clift, Andrew Carter, Ian H. Campbell, Malcolm S. Pringle, Nguyen Van Lap, Charlotte M. Allen, Kip V. Hodges, Mai Thanh Tan

Faculty Publications

Sand samples from the mouths of the Red and Mekong Rivers were analyzed to determine the provenance and exhumation history of their source regions. U-Pb dating of detrital zircon grains shows that the main sources comprise crust formed within the Yangtze Craton and during the Triassic Indosinian Orogeny. Indosinian grains in the Mekong are younger (210-240 Ma) than those in the Red River (230-290 Ma), suggesting preferential erosion of the Qiangtang Block of Tibet into the Mekong. The Red River has a higher proportion of 700-800 Ma grains originally derived from the Yangtze Craton. 40Ar/ 39Ar dating of muscovite grains …

Ms. Conroy offers a selected bibliography of resources to introduce researchers to the issues involved in the debate over the Act's reauthorization and its future implementation.

Assessment Of Pws System Effects On The Random Selection Of Jurors And The Demographic Characteristics Of The Jury Poll In The Superior Court Of Arizona, Maricopa County, Paula Hannaford-Agor, G. Thomas Munsterman

Faculty Publications

In July 2006, the Superior Court of Arizona, Maricopa County (Superior Court), contracted with the National Center for State Courts (NCSC) to review its jury management system. The Superior Court specifically requested that the NCSC Center for Jury Studies determine whether its Proximity Weighted Summoning (PWS) System randomly selects jurors from the master jury list for the county; whether the PWS System systematically excludes any identifiable group or population; and the effect of the PWS System on the demographic characteristics of jurors reporting at the various courthouse facilities in Maricopa County. The Superior Court also requested that the NCSC describe …

The 2005 Continuing Education Survey: What Science Librarians Want To Know, Elizabeth S. Hopkins, Terri Freedman, Camila Gabaldon, Virgina Baldwin, Jill Powell

Co-Variation In Soil Biodiversity And Biogeochemistry In Northern And Southern Victoria Land, Antarctica, Byron J. Adams, J. E. Barrett, Ross A. Virginia, Diana H. Wall, S. C. Cary, A. L. Hacker, J. M. Aislabie

Faculty Publications

Data from six sites in Victoria Land (72-77degrees S) investigating co-variation in soil communities (microbial and invertebrate) with biogeochemical properties show the influence of soil properties on habitat suitability varied among local landscapes as well as across climate gradients. Species richness of metazoan invertebrates (Nematoda, Tardigrada and Rotifera) was similar to previous descriptions in this region, though identification of three cryptic nematode species of Eudorylaimus through DNA analysis contributed to the understanding of controls over habitat preferences for individual species. Denaturing Gradient Gel Electrophoresis profiles revealed unexpectedly high diversity of bacteria. Distribution of distinct bacterial communities was associated with specific …

Quantifying Sulfate Components And Their Variations In Soils Of The Mcmurdo Dry Valleys, Antarctica, Huiming Bao, David R. Marchant

Faculty Publications

Many soils of the McMurdo Dry Valleys (MDV), Antarctica, being old, hyperarid, and frigid, have accumulated abundant atmospheric salts over the last several million years. This salt repository offers an opportunity to study atmospheric chemistry (past and present), the origin and transport of ions in soils, the weathering activity of soils, and postdepositional soil-leaching processes within this unique environment. In particular, soil sulfate in the MDV is known to have multiple origins, but the precise proportions of different sulfate components remain elusive. Here we test a hypothesis that soil sulfate in the MDV is a predictable mixture of three major …

Health In Cuba, Richard S. Cooper, Joan F. Kennelly, Pedro Orduñez-Garcia

Faculty Publications

The poorer countries of the world continue to struggle with an enormous health burden from diseases that we have long had the capacity to eliminate. Similarly, the health systems of some countries, rich and poor alike, are fragmented and inefficient, leaving many population groups underserved and often without health care access entirely. Cuba represents an important alternative example where modest infrastructure investments combined with a well-developed public health strategy have generated health status measures comparable with those of industrialized countries. Areas of success include control of infectious diseases, reduction in infant mortality, establishment of a research and biotechnology industry, and …

Is A Shutdown Of The Thermohaline Circulation Irreversible?, Jianjun Yin, Michael E. Schlesinger, Natasha G. Andronova, Sergey Malyshev, Bin Li

Faculty Publications

The Atlantic thermohaline circulation (THC) plays a vital role in explaining past abrupt climate changes and in maintaining the current climate. Its remarkable nonlinear dynamics, first demonstrated by H. M. Stommel, have been supported by various types of climate models. This has led to severe concerns that global warming may shut down the THC irreversibly, with consequent catastrophic climate changes, particularly for Europe. Here we use an uncoupled ocean general circulation model (OGCM) and a coupled atmosphere-ocean general circulation model (AOGCM) to investigate the nonlinear response of the THC to freshwater perturbations in the northern North Atlantic. We find that …

Will Lowering Estuarine Salinity Increase Gulf Of Mexico Oyster Landings?, R. Eugene Turner

Faculty Publications

Previous studies provide conflicting opinions on whether lower than average salinities in Gulf of Mexico (GOM) estuaries are likely to increase or decrease oyster harvests (Crassostrea virginica), which represented 69% and 54% of the United States oyster landings by weight, and dockside value, respectively, in 2003. The present study examined a 54-yr record (1950–2003) of oyster harvests and river discharge in five major estuaries in GOM states (Florida, Alabama, Mississippi, Louisiana, and Texas). Oyster landings were inversely related to freshwater inflow. Peaks in landings, 21 of 23 in West Florida, Alabama, Mississippi, and Texas combined, were coincidental with …

Systematics And Historical Biogeography Of Greater Antillean Cichlidae, Prosanta Chakrabarty

Faculty Publications

A molecular phylogenetic analysis recovers a pattern consistent with a drift vicariance scenario for the origin of Greater Antillean cichlids. This phylogeny, based on mitochondrial and nuclear genes, reveals that clades on different geographic regions diverged concurrently with the geological separation of these areas. Middle America was initially colonized by South American cichlids in the Cretaceous, most probably through the Cretaceous Island Arc. The separation of Greater Antillean cichlids and their mainland Middle American relatives was caused by a drift vicariance event that took place when the islands became separated from Yucatan in the Eocene. Greater Antillean cichlids are monophyletic …

No Variation And Low Synonymous Substitution Rates In Coral Mtdna Despite High Nuclear Variation, Michael E. Hellberg

Faculty Publications

Background: The mitochondrial DNA (mtDNA) of most animals evolves more rapidly than nuclear DNA, and often shows higher levels of intraspecific polymorphism and population subdivision. The mtDNA of anthozoans (corals, sea fans, and their kin), by contrast, appears to evolve slowly. Slow mtDNA evolution has been reported for several anthozoans, however this slow pace has been difficult to put in phylogenetic context without parallel surveys of nuclear variation or calibrated rates of synonymous substitution that could permit quantitative rate comparisons across taxa. Here, I survey variation in the coding region of a mitochondrial gene from a coral species (Balanophyllia elegans) …

Racially-Tailored’ Medicine Unraveled, Sharona Hoffman

Faculty Publications

In June 2005, the FDA approved BiDil, a heart failure medication that is labeled for use only by African-Americans and thus is the first treatment of its kind. The drug likely portends a future of growing interest in "race-based" medicine. This phenomenon is emerging at the same time that scientists, in light of the Human Genome Project, are reaching an understanding that "race" has no biological meaning, and consequently, "racially-tailored" medicine is both puzzling and troubling.

This Article explores the reasons for the new focus on "racial-profiling" in medicine. It analyzes the risks and dangers of this approach, including medical …

Accuracy Assessment Of Land Cover Maps Derived From Multiple Data Sources, Daniel Unger, Hillary Tribby, Hans Michael Williams, I-Kuai Hung

Faculty Publications

Maximum Likelihood (ML) and Artificial Neural Network (ANN) supervised classification methods were used to demarcate land cover types within IKONOS and Landsat ETM+ imagery. Three additional data sources were integrated into the classification process: Canopy Height Model (CHM), Digital Terrain Model (DTM) and Thermal data. Both the CHM and DTM were derived from multiple return small footprint LIDAR. Forty maps were created and assessed for overall map accuracy, user's accuracy, producer's accuracy, kappa statistic and Z statistic using classification schemes from U.S.G.S. 1976 levels 1 and 2 and T.G.l.C. 1999 levels 2 and 4. Results for overall accuracy of land …

When Policy Meets Practice: The Untested Effects Of Permanency Reforms In Child Welfare, Amy D’Andrade, J Berrick

Faculty Publications

The Adoption and Safe Families Act (P.L. 105-89; ASFA) passed into federal law in 1997. ASFA emphasized child protection over family preservation, and introduced reforms intended to increase the likelihood and the speed with which children in the child welfare system attain a permanent home. This article details two provisions of the law, concurrent planning and reunification exception, and explores challenges in their implementation. These provisions have the potential to shift the nature of how child welfare services are delivered, and which families will receive them. An examination of implementation in the state of California suggests there is a need …

Comparative Phylogeography In A Genus Of Coral Reef Fishes: Biogeographic And Genetic Concordance In The Caribbean, Michael S. Taylor, Michael E. Hellberg

Faculty Publications

Geographic barriers that limit the movement of individuals between populations may create or maintain phylogenetically discrete lineages. Such barriers are often inferred from geographic surveys of a single mitochondrial marker to identify phylogenetic splits. Mitochondrial DNA, however, has an effective population size one-fourth that of nuclear DNA, which can facilitate the rapid evolution of monophyletic mtDNA lineages in the absence of geographic barriers. The identification of geographic barriers will thus be more robust if barriers are proposed a priori, and tested with multiple independent genetic markers in multiple species. Here, we tested two proposed marine biogeographic breaks located at the …

The Taxing Power, The Sixteenth Amendment, And The Meaning Of ‘Incomes,’, Erik M. Jensen

Faculty Publications

This article examines the debates leading to the enactment of the 1894 income tax, which the Supreme Court struck down in 1895, and the Sixteenth Amendment, ratified in 1913, and concludes that an income tax and a tax on consumption were understood to be fundamentally different types of taxes. The author argues that the term “taxes on incomes” in the Sixteenth Amendment should be interpreted with that distinction in mind. The Amendment was intended to make a “tax on incomes,” and only a tax on incomes, possible without the apportionment that would otherwise be required for a direct tax. For …

Spatial Analysis Of Historic Cemeteries: Using High Spatial Resolution Imagery As A Visual Aid, Richard E. Brooks, Daniel Unger, I-Kuai Hung

Faculty Publications

Oak Grove Cemetery, located within the City of Nacogdoches in Nacogdoches County Texas, is one of the earliest cemeteries in the county dating to the early 1800’s. Several historic Texans are interred within this cemetery including Thomas J. Rusk and Charles S. Taylor who was the great-great-grandfather of current United States Senator Kay Bailey Hutchison. Due to a fire circa 1910 many of the records for the original section of the cemetery were lost. In the summer of 2006, the GPS coordinates of each grave marker within the cemetery were plotted on a backdrop of 6 inch spatial resolution multispectral …
