While lying down, a 23-year-old man detonated an improvised explosive device placed behind his head. The posterior neck and shoulders were singed, and much of the brain was avulsed. Death was due to laceration and partial avulsion of the cerebrum, midbrain, and brain stem. The injuries had a directional nature. Facts derived from the scene investigation and gross dissection, including nature, distribution, and extent of the wounds, in conjunction with preceding medical and social history, allowed for a reasonable reconstruction of the circumstances. 相似文献

The assessment of dangerousness is not a diagnosis, but rather a clinical impression based on the individual's past history
of violence and many other factors. With regard to the mental state, it has been noted that “the essence of dangerousness
appears to be a paucity of concern for others'” (Roth, 1974). As a subjective opinion, predicting violence and future dangerousness
bears the weight of much scrutiny and due diligence. Threat assessment evaluations have inherent social and legal ramifications,
and the responsibility must be accepted with the knowledge that accuracy may not always be achieved. This paper discusses
the various aspects of predicting future violence and dangerousness and the caveats that come with such tasks. 相似文献

Nitzan's (1991) analysis of differential sharing rules in a collective rent-seeking setting is reconsidered. Two groups, each with more than one member, are presumed to use different linear combinations of two sharing rules, one based on an equal-division of the prize, and the other on each member's relative effort. We show that an equilibrium always exists for this type of game, and then characterize the equilibrium. Our result is contrary to Nitzan's claims that (a) in the general case an equilibrium often does not exist, and (b) an equilibrium never exists when the groups use the polar extreme rules. 相似文献

Why a combatant command for Africa? I argue that AFRICOM was formed to implement the U.S. national security strategy that seeks to strengthen states and eliminate ungoverned space, as well as establish relationships with African states that offer a means to greater state stability and foster economic development. In so doing, it counters global jihadist by denying them haven among weak governments or in ungoverned areas. It protects U.S. interests in resources by helping governments become more stable. And it competes with the Chinese approach that could worsen the status quo of ineffective states and ungoverned space. Indeed, the U.S. approach of increasing state effectiveness makes African countries less susceptible to the problems that may arise from the Chinese approach and so serves China's interests in access to natural resources. 相似文献

Abstract: Pork ribs with intact muscle tissue were used in an experimental attempt to identify bullet wipe on bone at distances from 1 to 6 feet with 0.45 caliber, full metal jacket ammunition. This resulted in the unexpected finding of primer‐derived gunshot residue (GSR) deep within the wound tract. Of significance is the fact that the GSR was deposited on the bone, under the periosteum, after the bullet passed through a Ziploc® bag and c. 1 inch of muscle tissue. It is also important to note that the GSR persisted on the bone after the periosteum was forcibly removed. The presence of primer‐derived GSR on bone provides the potential to differentiate gunshot trauma from blunt trauma when the bone presents an atypical gunshot wound. In this study, the presence of gunshot primer residue at a distance of 6 feet demonstrates the potential for establishing maximum gun‐to‐target distance for remote shootings. 相似文献
