This research study explores the relationship of urbanization to ecology in the wadeable streams of developing watersheds and describes a protocol, which urban stormwater management agencies can apply in their jurisdiction, to prevent the severe ecologic deterioration that presently occurs in urban streams as a watershed develops. The protocol comprises an 8-step process that involves data collection and analysis integrated with mathematical modeling of runoff from existing and proposed urban development to determine how biologic health indices such as the benthic index of biotic integrity (B-IBI) or Ephemeroptera, Plecoptera, Trichoptera (EPT) richness responds to urbanization of a watershed.
Comet and Asteroid Impact Hazards explores the anticipated consequences of comet and asteroid impact. It presents the first computer simulations of the hazards of comet and asteroid bombardment of a populated Earth. Previous estimates of fatality and damage rates on the 100 to 10,000 year time scale are shown to be too low because they neglect rare, highly lethal outriders of the populations of bombarding objects, those with exceptional strength, unusually low entry velocity, and near-horizontal entry angles. This is the first realistic assessment of both the mean casualty rate and the expected statistical fluctuations in that rate. A breakdown of fatality and damage rates by impactor energy and compositional class suggests lessons for both asteroid search strategies and interdiction techniques.
* Quantatively rigorous treatment of the state of impact hazard prediction, including stuctural blast damage, firestorm ignition, tsunami generation
Identity theft is one of the fastest growing crimes in the United States, costing $52.6 billion in 2004 alone. Victims of identity theft suffer long-term and welldocumented pain and suffering. This is particularly true for senior citizens who comprise the demographic group most frequently victimized by this crime. A review of literature revealed that training has led to positive changes in the attitudes and behaviors of trainees. Although there has been limited research on the impact of training with respect to identity theft prevention strategies, previous work by McKenna and Miller examined the effectiveness of the Citizens Against Senior Exploitation (CASE) Training Model on the attitudes and behaviors of trainees with respect to identity theft prevention. This study provided validity for McKenna and Miller's work and focused specifically on senior citizens, with the goal of helping to address the needs of the group most vulnerable to identity theft predators. Both a treatment group and a comparison group of senior citizens were utilized to examine the changes in their attitudes and behaviors with respect to identity theft prevention. The findings indicated that the CASE Training Program influenced the adoption of identity theft prevention techniques by senior citizens.
