    A Comparative Analysis of John Walton and John Sailhamer on Gen. 1:1

    Much ink has been spilled over the interpretation of Gen. 1:1, particularly in modern times. While these interpretations are diverse, two authors that deviate away from most identifiable norms are John Sailhamer and John Walton. Sailhamer thinks Gen 1:1 is a literal event that took place over an indeterminate block of time preceding the rest of creation. Walton, on the other hand, questions the presupposition of material ontology present in many contemporary accounts of creation, arguing instead that God’s creating should be understood as assigning function. This essay will seek to compare both scholars’ views, summarizing them, finding possible convergences, and areas of divergence. Having established these positions, it will be argued that Sailhamer has the stronger case to make

    Sustainable agricultural land tenure and risk management for extreme climatic events

    The researchers studied how landowners and farmers are working to improve conservation and protect productivity, soil health and water quality while facing extreme weather. The project results yielded more future research questions than definitive answers as to how non-owner landlords and their tenants can work together to safeguard the land and its productivity

    Tectonics and Alteration of Oklahoma Basement Rocks

    Get PDF
    The igneous and metamorphic rocks which underlie the sedimentary section of an area (colloquially referred to as “basement” rocks) exert substantial influence on the overlying younger rocks. Large structural features are rooted in basement rocks, and additionally the basement usually contains the only available information regarding the pre-sedimentary geological history. Secondary alteration processes in basement rocks can significantly change their mineralogy and mechanical properties. Understanding of geological history and regional structures within a given area therefore requires study of its basement rocks. This dissertation utilizes petrographic, geochemical, structural, and magnetic approaches to study the basement rocks of Oklahoma. New petrographic observations of the Mesoproterozoic Osage Microgranite in northeastern Oklahoma provide evidence of deformation and secondary alteration and suggest a possible extrusive origin for this unit. Geochemical data additionally suggest a subduction-related origin. Study of several cores in northeastern Oklahoma shows that fracturing and hydrothermal alteration are pervasive in the area’s basement rocks, in contrast to common assumptions of intact granite used in modeling studies of induced/triggered seismicity. Magnetic susceptibility measurements of some altered basement rocks and overlying clastic sediments show highly unusual properties, including a strongly negative relationship between susceptibility and the strength of the measuring field. Detailed study shows this is likely due to an unknown magnetic mineral which saturates at very low fields and has a Curie temperature near 85 °C. Paleomagnetic study of the ~1370 Ma Spavinaw Granite yields evidence of remagnetization in the early Cambrian and in the middle Paleozoic. Magnetic fabric data suggests it is either strongly tilted relative to its original emplacement or was emplaced as a dike rather than a horizontal sill. Paleomagnetic data from intermediate and mafic rocks associated with the early Cambrian Glen Mountains Layered Complex in southwestern Oklahoma provide a new constraint on the paleogeography of Laurentia, with implications for various hypotheses relating to early Cambrian geomagnetic behavior. Additionally, some sites show evidence of partial to complete remagnetization in the middle and late Paleozoic

    South Skagit Highway realignment: ENVS 493 winter 2013

    Get PDF
    The existing placement of the South Skagit Highway disconnects the Skagit River from approximately 62 acres of floodplain in the project area alone and has direct impacts on habitat conditions. Approximately, 5.2 acres of wetlands are completely inaccessible to fish due to the current highway alignment. An additional 21.7 acres of slough and wetland habitat have only partial fish access due to restricted hydrologic connectivity with the river. Routine dredging and maintenance is required for the 900 feet of Savage Creek which currently runs in the highway ditch. Savage Slough runs under the highway through an undersized culvert that is often blocked by flooding from Mill Creek. An alluvial fan of Mill Creek runs under an undersized bridge making the channel prone to migration, avulsion, and erosion. The channel has been subject to numerous maintenance projects, including dredging and channelization. Seattle City Light (SCL) purchased approximately 212 acres of property on the Skagit River near Mill and Savage Creeks. A large portion of the acquired property has been deforested and disturbed by the South Skagit Highway, which runs through the Skagit River\u27s floodplain and disconnects a variety of existing tributary and wetland habitats. In order to implement habitat restoration and protect the property for conservation, SCL has been working with Skagit River System Cooperative (SRSC) and Skagit County to restore the floodplain to its original ecological functionality, providing habitat for several species. Maintenance costs of the current road would also be reduced. The restoration is likely to include demolition, riparian and floodplain plantings, and culvert removals. Possibilities for floodplain restoration were evaluated after an initial scoping procedure. Suggested restoration would either demolish and realign the existing road or install new bridges and culverts on the existing road. The initial scoping and evaluation narrowed the list of feasible projects down to two, mostly due to the Washington State Department of Transportation\u27s (WSDOT) high cost estimate of the other projects. Project funding has come from both SCL and the Salmon Recovery Funding Board (SRFB, project #091450) and several additional sources

    Modelling Sand Fly Lutzomyia longipalpis Attraction to Host Odour: Synthetic Sex-Aggregation Pheromone Dominates the Response.

    Get PDF
    Zoontic visceral leishmaniasis (ZVL) due to Leishmania infantum is a potentially fatal protozoan parasitic disease of humans and dogs. In the Americas, dogs are the reservoir and the sand fly, Lutzomyia longipalpis, the principal vector. A synthetic version of the male sand fly produced sex-aggregation pheromone attracts both female and male conspecifics to co-located insecticide, reducing both reservoir infection and vector abundance. However the effect of the synthetic pheromone on the vector's "choice" of host (human, animal reservoir, or dead-end host) for blood feeding in the presence of the pheromone is less well understood. In this study, we developed a modelling framework to allow us to predict the relative attractiveness of the synthetic pheromone and potential alterations in host choice. Our analysis indicates that the synthetic pheromone can attract 53% (95% CIs: 39%-86%) of host-seeking female Lu. longipalpis and thus it out-competes competing host odours. Importantly, the results suggest that the synthetic pheromone can lure vectors away from humans and dogs, such that when co-located with insecticide, it provides protection against transmission leading to human and canine ZVL
