Participants (N = 200) were presented with a criminal homicide trial involving a battered woman who had killed her abuser. Within the trial, both the response history (passive, active) and presence of expert testimony pertaining to battered woman syndrome (present, absent) were systematically varied. As well, half of the participants in each of these conditions were provided with a nullification instruction informing them that they were free to disregard the law and acquit should a strict application of the law result in an unjust verdict. Results indicated that, compared to the passive response condition, the mock jurors were no less receptive to the expert testimony in the active response condition. The impact of the testimony on participants' verdicts, however, was moderated by the nullification instruction. That is, although the presence of the testimony did result in greater verdict leniency, this only occurred when the mock jurors had been released from a strict application of the law. The implications of these findings are discussed.  相似文献

Mediators, called night correspondents, have been hired by some French municipalities to reduce violence in the neighborhoods, using dialogue and daily help (in repairing things in particular). Night correspondents seem to be especially appropriate to reduce incivility, i.e. daily nonrespectful behavior. This essay reports on the results of two surveys conducted in Cergy by MBA students of two seminars at ESSEC business school. Although the recommendation of hiring night correspondents has not been followed yet in Cergy, several decisions have been taken by the social lessors and other public actors in the neighborhoods aimed at reducing violence, through mediation processes.  相似文献

Nuclear magnetic resonance (NMR) spectroscopy was employed for the purpose of identifying samples of materials suspected of containing sodium fluoroacetate (Compound 1080). Acquisition of routine proton (1H) and carbon (13C) NMR spectra provided a straight-forward means for determining the presence of Compound 1080 in the samples and thus afforded a simple method for analysis and identification of this compound.  相似文献

Current procedures for human DNA quantitation reach their limit at 150 pg DNA, which is above the limit of the PCR profiling range using Profiler-Plus (Applied Biosystems, CA). This study tested the potential for the use of primate specific Alu sequences in forensic science for the sensitive detection and quantitaion of DNA. A fluorescently labelled primer pair was designed enabling high efficiency amplification of the core Alu sequence within primate DNA. Quantitation was performed by measurement of fluorescence intensity and comparison to a series of standard template DNA amounts via the construction of a standard curve. The new Alu-based quantitation protocol developed has shown its feasibility in more sensitively quantitating (100-2.5 pg) unknown amounts of human DNA for forensic use. The method is compatible with the use and throughput of current forensic procedures.  相似文献

A statistical evaluation of injuries of head tissues inflicted by blows with human body parts and with blunt hard objects of communal use was carried out. Characteristic morphometrical and topographical features of injuries and factors essential for their severity are defined.  相似文献

The morphology of adrenals was studied in cases of death from total supercooling. The intensity and terms of response are different in different morphofunctional zones of the adrenal cortex. Presumably, the terms and intensity of responses of various portions of the adrenal cortex reflect the specific features of their function regulation.  相似文献
