Large oil spills in the United States often result in some natural resource damages (NRD), which arise from injuries to natural resources and losses of their services. We use multiple regression analysis to identify the factors that explain variations in NRD settlements, including: spill amount, whether threatened and endangered species were injured, whether recreation closures occurred, some temporal factors, some geographic factors, and some characteristics of the government agencies pursuing NRD. Then, we use our preferred statistical model to predict the median and confidence interval for the NRD settlement for future oil spills with specified characteristics. Such predictions for future spills will be helpful in determining the appropriate scale for the NRD assessment and for setting aside reserves for settlement.  相似文献

ABSTRACT

Two paradigms inform responses to active shooting situations: a traditional lockdown approach where individuals find cover in a classroom and lock the door, and a multi-option approach where individuals evacuate the area, create barricades, and, in last resort situations, actively resist the gunman. While a majority of schools conduct active shooter drills, typically using a traditional lockdown approach, little is known about their effectiveness. Through simulations, this study sought to determine which of the two paradigms that inform active shooter drills is the most effective. Drills informed by the multi-option response paradigm were found to end more quickly and result in fewer people being shot.  相似文献

Visual identification is the most common identification method used by medical examiners but is not always possible. Alternative methods include X‐ray, fingerprint, or DNA comparison, but these methods require additional resources. Comparison of serial numbers on implanted medical devices is a rapid and definitive method of identification. To assess the practicality of using this method, we reviewed 608 consecutive forensic autopsies performed at a regional medical examiner office. Of these, 56 cases required an alternative method of identification due to decomposition (n = 35), gunshot wound (n = 9), blunt trauma (n = 6), or charring (n = 6). Of these 56 cases, eight (14.3%) were known to have an implanted medical device. Of these eight cases, five (63%) could be positively identified by comparing serial numbers. If an implanted medical device is known to be present, and medical records are available, identification by medical device serial number should be a first‐line method.  相似文献

Estimation of postmortem interval (PMI) is a critical component of death investigation. A cadaver can be hypothesized to be a resistor–capacitor (RC) circuit the impedance (Z) of which changes in a quantifiable manner as the cadaver decomposes. This hypothesis was tested using bioelectrical impedance analysis (BIA) equipment to apply a current with a fixed amplitude at a single frequency to four cadavers over time and measuring two components of Z, resistance (R) and reactance (Xc). Quadratic regression analysis between Z and accumulated degree days (ADD) showed a statistically significant parabolic relationship. The parabolic relationship poses an initial challenge to the use of the method, and additional research is needed to address this issue. However, the results of the reported research support the hypothesis that Z measured using BIA has a relationship to PMI.  相似文献

The majority of incarcerated women who suffer from diverse traumatic life histories including abusive home lives and intimate partner violence (IPV), develop post-traumatic stress disorder (PTSD) and struggle with heavy illicit drug use. While many have offered examinations of these relationships, the current study is among the first to utilize an integrated feminist pathways and general strain theory (GST) approach to explain them. Using data from a stratified random sample of all incarcerated women in Oklahoma (N = 334), we explore the links between, adverse childhood experiences, including physical, sexual, emotional, and childhood neglect, IPV, PTSD, and heavy illicit drug use. Our findings indicate that the effects of IPV on heavy illicit drug use are mediated by PTSD symptoms suggesting that PTSD plays a significant role in the pathway to illicit drug use among Oklahoma women prisoners. Implications for the importance of utilizing an integrated feminist pathways and GST approach in future research are offered.  相似文献
