Time since discharge of shotgun shells

A technique for the estimation of time since discharge of a given class of spent shotgun shells is presented. The technique involved the use of SPME (Solid Phase Microextraction) sampling from the atmosphere inside spent shotgun shells. Compounds absorbed on the SPME fiber were desorbed and analyzed with GC-MS. The decrease in concentration of the combustion product naphthalene was monitored in all shells over a two-month period. Three conditions were examined to prevent naphthalene from escaping prior to testing the shells. A glass vial was successfully incorporated to halt the dissipation of naphthalene. At room temperature the naphthalene peak can be measured for several months and the curve-fitting data can lead to an estimation of time since discharge.     

In the Aftermath of the Storm: US Foreign Policy in the Wake of 9/11 and its Implications for the Asia-Pacific region

In the following article, Kurt M. Campbell, senior vice-president and director of the International Security Program (ISP) at the Center for Strategic and International Studies (CSIS), Washington, DC., and Yuki Tatsumi, ISP research associate at CSIS, explore the changes that have taken place in US foreign policy since the terrorist attacks of 11 September 2001 and how such changes might be reflected on its policy toward the Asia-Pacific region. They point out that the US will shift its focus to security at home and war on terrorism abroad. In the short-term, US focus will deviate from Northeast Asia to Southeast, Central and South Asia, but as the region will continue to be strategically important, the US will remain engaged in the region. It is up to the countries in the Asia-Pacific to ensure that the US engagement in their region is not dominated by unilateralism and excessive preoccupation with the war against terrorism.     

Information Resources Management Expenditures in the States: A Case for Integrating Accounting and Budgeting Systems

A recent national study has found that states may be spending $20 billion on information resources management (IRM) in FY1989. The significant findings of the study regarding financial management are highlighted to show the dimensions of the IRM expenditures in the states. The second part of the paper examines how well the states' accounting systems are able to provide data on IRM expenditures for budgetary decisions. The article expands upon an important issue raised in the study's findings: the need for better integration of accounting and budgeting systems to improve management of information resources. An Information Object Classification Scheme, first suggested by the Commission on Federal Paperwork, is proposed as an important step in helping states improve their information resources management.     

Comparative Evaluation of Potentially Radiolucent Projectile Components by Radiographs and Computed Tomography

Projectile components that are traditionally radiolucent can be of considerable importance in determination of weapon type and caliber, but they are often missed on evaluation of postmortem radiographs. We hypothesized that these components would be significantly better visualized by evaluation of computed tomography (CT) scans compared to the practice standard of radiography alone. In this project, potentially radiolucent projectile components were both pulled apart and fired, and the radiolucent components were recovered. These components were embedded in blocks of ballistics gelatin and were imaged using both radiography and CT. The scans were evaluated by three blinded, board‐certified radiologists for the presence/absence of projectile components and true‐negative regions in each block. If a radiologist indicated visualization of a projectile component, they were further requested to describe their observation. It was found that traditionally radiolucent projectile components are not significantly more often identified on CT scans than radiography (p < 0.05).     

John and Jane Doe: the epidemiology of unidentified decedents

Abstract:  The number of people who cannot be identified at the time of death, sometimes referred to as John or Jane Does, is unknown, and little is known about them as a group. The study's objectives were to estimate the number of annual unidentified deaths, to identify demographic characteristics associated with dying unidentified, to determine whether the rates of such deaths vary geographically or over time, and to better characterize the causes of death. This was a population-based surveillance study of data collected from death certificates from 1979 to 2004 in the U.S. Subjects were selected by the absence of name, date of birth, and Social Security Number on their certificates. Main outcome measures were distributions by age, sex, and underlying cause of death and rates by sex, race, year, and state of death. An average of 413 unidentified persons died each year. The peak year was 1987 with 691 deaths, a rate of 28.5 per 10 million people. The rate declined to 9.7 per 10 million in 2004. Most unidentified decedents were male (80.6%). Unidentified death rates were highest among black people and in the Southwest. Among deaths for which the cause was known, 82.7% were due to injuries. Among injury deaths, 31.8% were homicides. Improvement in identification technology may have reduced rates of unidentified death since the 1980s. In addition, variations in rates of unidentified decedents may reflect changes in risk factors such as homelessness and substance abuse.
