Following the Hinckley acquittal, 17 states and the federal government made changes to the insanity defense, including revising the standard, reassigning the burden of proof, and altering the standard of proof. Two studies were conducted to determine whether the specific insanity standard (including the assignment of burden of proof and standard of proof) employed had a significant effect on mock jurors' verdicts. Participants' comprehension of insanity defense instructions was measured and the factors jurors used to decide whether to find the defendant not guilty by reason of insanity (NGRI) were also assessed. Participants' comprehension of insanity defense standards was very low. When asked to identify the factors they considered important in determining whether to find a defendant NGRI, only three elements of insanity defense standards were identified as significant. The results may have important implications for policy decisions regarding the insanity defense.  相似文献

Nathan  Maehala R. 《Trusts & Trustees》2007,13(10):604-607
Trusts continue to play an important role in asset protectionplanning. But annuities and life insurance, and in particularSwiss annuities, are a viable alternative in many cases. Furthermore,the combination of both structures, in most cases can resultin benefits that go beyond that of a pure trust structure ora sole annuity. The mechanics of these advantages are examinedin this article.  相似文献

The authors compared arch width measurements of diagnostic dental models obtained from dental school patients. Arch width measurements were taken in the canine area on each dental cast in an effort to assist forensic dental investigators in matching certain classes of subjects to the bites they might possibly inflict. If any canine teeth were absent, the measurements were taken using other specified adjacent teeth which the investigators felt would be interpreted as the arch width determiners in a bite mark injury. The ages of the subjects varied from 14 to 87 years. Statistical comparison of the maxillary arch width, mandibular arch width, and the mean difference between maxillary and mandibular arch width were performed. Significant differences between the arch width measurements were found to exist between several classes of subjects based on race and sex.  相似文献

Autoerotic death. A definition   总被引:1,自引:0,他引:1  
A definition of autoerotic death is suggested that restricts the use of this term to accidental deaths that occur during individual, usually solitary, sexual activity in which a device, apparatus, or prop that was employed to enhance the sexual stimulation of the deceased in some way caused unintended death. The case of the autoerotic asphyxial death of a 48-year-old man is reported in order to demonstrate the application of this definition.  相似文献

Urgent problems of scientific research on medicolegal evaluation of vehicle trauma were studied. One of perspective ways of increasing scientific control and evidential value of expert conclusion is pointed out. Use of mathematical methods and personal computers in expert evaluation of vehicle trauma is recommended. Expert differential diagnostic system (impact-overrun) developed is described and operating condition of personal computer is given.  相似文献

This model evaluates the use of dental stone casts derived from maxillary tissues and from the internal aspects of maxillary dentures for edentulous postmortem identification. Tissue topography of the total cast and of rugae tracings photographed from the casts were evaluated for identification accuracy in twenty-eight trials for each of the two designs. Eight casts were examined in each trial. The trial was designed as matching or nonmatching, and as an equivocal or unequivocal decision by the examiner. Unequivocal decisions with 100% accuracy resulted when the entire dental cast was evaluated. Seventy-nine percent accuracy with equivocation in some trials resulted when only rugae tracings from the casts were evaluated. This investigation supported use of stone casts derived from the internal anatomy of maxillary dentures for forensic science identification when cast topography in toto was considered.  相似文献
