Abstract:
The Twenty-Second Annual Conference of the Association of MuslimSocial Scientists (AMSS) was jointly organized by the Intemational Instituteof Islamic Thought (IIIT) and the AMSS and was held at the IIITpremises in Hemdon, VA. The open-theme conference featured eighteenpanels organized into fourtem sessions.The opening session consisted of the welcoming address by DilnawazSiddiqui, President (Clarion University of Pennsylvania, Clarion, PA), remarksby Mushtaqur Rahman, Conference Chairman (University of Iowa,Ames, IA), and the inaugural address of Taha al 'Alwani (President,IIIT). The second session, "Islamic Philosophy and Compamtive Approaches,"was chaired by Ja'afar Sheikh Idris (Institute of Islamic andArabic Sciences, Fairfax, VA). Presentations included "Islamic Theory ofKnowledge: A Reapptaisal" by Sirajul Husain (Islamic Research and DevelopmentCouncil, Cleveland, OH), "Islamization of the Creative Imaginationand Its Ramifications in the Visual Arts of Islam" by Halide A.Salam (Radford University, Radford, VA), and "The Concept of Free Willin the Comments of al Ash'ari, al Hilli, and Taftazani" by Anne E.Francisse (Seattle, WA).The third session had two concurrent panels: "Concept of Shzird andDemocracy in Islam," chaited by Mumtaz Ahmad (Hampton University,Hampton, VA) and "Culture and Communication," chaired by Ali Ramadan(IIIT). The first panel comprised Aziza a1 Hibri (University of Richmond,Richmond VA) and Ja'afar Shaikh Idris. Al Hibri pointed out thatshura (mutual consultation) is part of Islamic constitutional theory and reflectsthe divine dimension of an Islamic political framework-while democracyis one process of shzirti reflecting the human will in the politicalplane.

Abstract:
Green infrastructure (GI) protects aquatic ecosystems from stormwater runoff caused by urban development. Bioretention (BR) is a typical GI system wherein stormwater runoff is routed to a soil basin planted with vegetation and has been shown to reduce deicing salt loads in surface runoff, but the removal mechanism of salt is poorly understood. This study explores the potential of different vegetation types to reduce deicing salt released from a BR by transpiration. Six engineered soil media columns were built in a laboratory greenhouse to simulate a 1012 m2 BR basin along Lorton Road, Fairfax County, VA, USA. The effect of vegetation type (Blue Wild Indigo and Broadleaf Cattail) and influent salt concentration on flow volume and salt mass reduction were quantified for multiple storm events. For all storm events, chloride inflow concentrations, and vegetation types, Cl− load reduction ranged from 26.1% to 33.5%, Na+ load reduction ranged from 38.2% to 52.5%, and volume reductions ranged from 11.4% to 41.9%. Different inflow salt concentrations yielded different removal rates of deicing salt, and for a given column, salt removal decreased over sequential storm events. For each influent salt concentration, columns planted with Broadleaf Cattail (BC) performed better for volume and salt mass reductions than columns planted with Blue Wild Indigo (BWI), which in turn performed better than the controls.

Abstract:
ABSTRACTBacillus thuringiensissubsp.kurstakiis applied extensively in North America to control the gypsy moth,Lymantria dispar. SinceB. thuringiensissubsp.kurstakishares many physical and biological properties withBacillus anthracis, it is a reasonable surrogate for biodefense studies. A key question in biodefense is how long a biothreat agent will persist in the environment. There is some information in the literature on the persistence ofBacillus anthracisin laboratories and historical testing areas and forBacillus thuringiensisin agricultural settings, but there is no information on the persistence ofBacillusspp. in the type of environment that would be encountered in a city or on a military installation. Since it is not feasible to releaseB. anthracisin a developed area, the controlled release ofB. thuringiensissubsp.kurstakifor pest control was used to gain insight into the potential persistence ofBacillusspp. in outdoor urban environments. Persistence was evaluated in two locations: Fairfax County, VA, and Seattle, WA. Environmental samples were collected from multiple matrices and evaluated for the presence of viableB. thuringiensissubsp.kurstakiat times ranging from less than 1 day to 4 years after spraying. Real-time PCR and culture were used for analysis.B. thuringiensissubsp.kurstakiwas found to persist in urban environments for at least 4 years. It was most frequently detected in soils and less frequently detected in wipes, grass, foliage, and water. The collective results indicate that certain species ofBacillusmay persist for years following their dispersal in urban environments.

Abstract:
An unidentified species of Phytophthora was isolated from irrigation water at a production nursery in Suffolk, VA in 2000 and 2001. Water samples were assayed using a filtration method (3). A similar species was recovered from soil samples collected in two mixed-hardwood forests in Fairfax County in 2002. Soil samples were air dried, remoistened, flooded, and then baited with rhododendron and camellia leaf pieces at room temperature (22 to 24°C) (2). A Phytophthora sp. was recovered from bait pieces cultured on PARPH-V8 selective medium (2). This same species also was isolated from symptomatic leaves of Pieris japonica cv. Temple Bells and Rhododendron catawbiense cv. Maximum Roseum at a garden center in Virginia Beach in 2004. On P. japonica, symptoms appeared as water-soaked, necrotic lesions and marginal necrosis on leaves and necrosis of shoot tips; on R. catawbiense, symptoms were wilting, dieback, and death of shoots. Representative isolates produced semipapillate to papillate sporangia with tapered bases that were caducous and had long pedicels (16 to 120 μm). Sporangia on four isolates were measured: mean lengths were 40.6 to 48.4 μm, mean widths were 26.9 to 31.4 μm, and length/width ratios consistently were 1.5. Sporangia occasionally were distorted and had dual apices, and they often contained a large globule after zoospore release. Chlamydospores ranged from 25 to 32 μm in diameter. All isolates were heterothallic; four isolates paired with known isolates of P. nicotianae were found to be mating type A1. Optimum temperature for mycelium growth on cornmeal agar was 25°C with slight growth at 35°C by some isolates and no growth at 4°C. These morphological characteristics were mostly consistent with those of P. tropicalis (1). P. tropicalis is reported to have sporangia that are papillate, have lengths of 40 to 55 μm, widths of 19 to 27 μm, and length/width ratios of 1.8 to 2.4 (1). The identity of these isolates as P. tropicalis was confirmed using single-strand conformational polymorphism analysis with comparison to a reference isolate (4). These isolates have been retained in permanent collections in the Hong and Jeffers labs. One isolate from each host plant and one isolate from irrigation water were tested for pathogenicity; agar blocks of mycelium (4 × 4 mm) were placed on wounded and nonwounded leaves of P. japonica cv. Mountain Fire and R. catawbiense cv. Olga plants and wrapped with Parafilm to prevent desiccation. Lesions formed on wounded and nonwounded leaves after 4 days at 20 to 30°C, and P. tropicalis was reisolated; no lesions formed on noninoculated control leaves. To our knowledge, this is the first report of P. tropicalis in the continental United States, in irrigation water systems, and as a cause of Phytophthora foliage blight on P. japonica and R. catawbiense (1). This study suggests that the host range of this pathogen is not limited to tropical plants. Although this pathogen did not cause significant economic loss in the garden center surveyed, it was isolated in irrigation water at the production nursery from late spring through fall. An investigation of its impact on nursery crops is warranted. References: (1) M. Aragaki and J. Y. Uchida. Mycologia 93:137, 2001. (2) A. J. Ferguson and S. N. Jeffers. Plant Dis. 83:1129, 1999.

Abstract:
This study examines racial and ethnic disparities in the use of force by the Fairfax County, VA Police Department using post-Ferguson data and after the adoption of modern training and use of force policies on de-escalation. White civilians were overrepresented as subjects of force compared to a variety of benchmarks, while Hispanics were underrepresented. Black and Asian civilians also were overrepresented using some benchmarks but not others. Multivariate models revealed that Black civilians experienced more severe force, higher average force levels, and more total force than Whites. We discuss possible reasons for the overrepresentation of Blacks and Whites as subjects of force, as well as the disparities in force levels and the totality of force experienced by Black civilians. We conclude with suggestions for policy change, training, and deployment changes to help reduce the potential influence of unconscious bias in the application of force by the FCPD and other law enforcement agencies.

Abstract:
Contaminant fate and transport are two of the most important issues project officers have to deal with when developing a sound remediation strategy for a subsurface contamination site. To accurately assess these issues, knowledge of possible pathways, travel times and groundwater receptors are required. A groundwater flow model of a site facilitates the assessment process by determining flow paths, discharge areas and travel time from a contaminant source to a potential receptor. The resulting model can also be used to show potential impacts on drinking water sources and surface habitats. This project is Phase II of the proposed three phase project, Groundwater Flow Modeling of the Aquifer System at Ft. Belvoir (Widdowson, 1998). Phase I consisted of developing a conceptual model of the aquifer system, recommending a modeling strategy and developing a data collection strategy. The objectives of this phase are to design and construct a computer simulation of the groundwater flow system in the aquifers below Ft. Belvoir and to develop a strategy for improved data collection using the results of the model. Steps in this phase included creation of the numerical model, calibration to known water surface elevations, and a sensitivity analysis of the boundary conditions. The numerical model was created in the Department of Defense Groundwater Modeling System environment using MODFLOW. The model was calibrated to pre-1970 wells for the deep aquifer and recent site characterization wells for the upper aquifer. The head distribution was influenced the greatest by topography and the major creeks. Accuracy of the well surface elevations played a major role in the calibration process, as well as tidal influences. A sensitivity analysis showed that adjusting the recharge and the seepage face parameters affected the model results (head and groundwater flow rates) the greatest. While adjusting the constant head and general head boundaries affected the model results the least.

Abstract:
This study uses the Natural Resources Conservation Service (NRCS) TR-55 method to quantify the increase in stormwater runoff volume from infill residential redevelopment, or mansionization, in a 34-acre residential subwatershed of Fairfax County, Virginia. Analysis of 10 redeveloped lots in the subwatershed showed an average increase in impervious cover from 8% to 28% after redevelopment, resulting in an average increase in runoff volume of 18% for the 10-year, 24-hour storm. From 1997 to 2009, the total impervious cover in the subwatershed increased from 18% to 25%, resulting in a calculated 6% increase in runoff volume. Low Impact Development (LID) techniques were modeled as retrofits in the subwatershed to mitigate the increase in runoff volume. Measures modeled include bioretention basins, infiltration trenches, amended soils, permeable pavement, and cisterns. Results indicate that placing bioretention basins or infiltration trenches on 0.5% of the subwatershed or amending 20% of the open space with soil composts would reduce the runoff volume back to the 1997 quantity for the 1-year, 24-hour storm.

Abstract:
The three professions of planning, architecture, and urban design, tend to work separately, but in fact, they are related. The disciplines are combined in this project to illustrate a comprehensive approach to land development. The project presented here integrates planning, architecture, and urban design, and provides a variety of housing types atypical in suburban development. It also illustrates several housing types on a specific site, utilizing the planning, zoning and subdivision regulations of the two jurisdictions.
