The National Institute of Justice (NIJ) and the National Aeronautics and Space Administration's (NASAs) Goddard Space Flight Center (GSFC) have teamed up to explore the use of NASA developed technologies to help criminal justice agencies and professionals solve crimes. The objective of the program is to produce instruments and communication networks that have application within both NASA's space program and NIJ programs with state and local forensic laboratories. A working group of NASA scientists and law enforcement professionals has been established to develop and implement a feasibility demonstration program. Specifically, the group has focused its efforts on identifying gunpowder and primer residue, blood, and semen at crime scenes. Non-destructive elemental composition identification methods are carried out using portable X-ray fluorescence (XRF) systems. These systems are similar to those being developed for planetary exploration programs. A breadboard model of a portable XRF system has been constructed for these tests using room temperature silicon and cadmium-zinc telluride (CZT) detectors. Preliminary tests have been completed with gunshot residue (GSR), blood-spatter and semen samples. Many of the element composition lines have been identified. Studies to determine the minimum detectable limits needed for the analyses of GSR, blood and semen in the crime scene environment have been initiated and preliminary results obtained. Furthermore, a database made up of the inorganic composition of GSR is being developed. Using data obtained from the open literature of the elemental composition of barium (Ba) and antimony (Sb) in handswipes of GSR, we believe that there may be a unique GSR signature based on the Sb to Ba ratio. 相似文献

We hypothesized that incongruous misfortunes generate stronger affective reactions and perceptions of injustice than do equally
severe and equally probable congruous misfortunes. Incongruous misfortunes are defined as ones that bring to mind thoughts
or images of the misfortune either happening to a different person or happening to the same person by a different means. In
a series of studies, victims of incongruous negative life events (e.g., wartime casualties of “friendly” five) were expected
to experience stronger reactions of regret, shock, outrage, and perceived injustice than victims of more congruous versions
of the same events. Differences between reactions to incongruous misfortunes and subjectively improbable misfortunes are explored. 相似文献

The history of tribal-state conflict and the role of the federalgovernment is nearly two centuries old. In recent years, themost contentious source of conflict between American Indiantribes and states has been Indian gaming. The Congress attemptedto compromise and resolve the issue by passing the Indian GamingRegulatory Act (IGRA) in 1988, but the law has only exacerbatedand opened up new avenues of conflict. The scope and stakesof Indian gaming can be seen in the history of Indian gamingin New Mexico where the defects in IGRA have been readily apparent.As Indian gaming has grown, so have efforts to curtail it andother aspects of tribal sovereignty, including tribal sovereignimmunity. These efforts are currently underway in the Congress. 相似文献
