This paper examines the pervasive conviction that sex offenders - particularly child molesters - will continue to re-offend. This belief in inevitable recidivism turns out to be absolutely essential to both the justification for, and the structure of, the sexually violent predator laws. When actual evidence of sex offender recidivism is examined, however, a huge gap exists between what is assumed and what the data actually show because most sex offenders do not in fact re-offend. Thus there is a galaxy of sexually violent predator laws and an entire branch of Supreme Court jurisprudence that is founded upon a demonstrable urban legend.  相似文献

This paper seeks to address the divide between political rhetoric and reality on the question of the impact of the Internet on China. Many politicians and pundits steadfastly promote the Internet as a conduit for democracy, without empirical proof to support their statements. Nowhere is this more apparent than in the debate over information technology and the Internet in China. The Chinese Communist Party is employing a number of approaches to control the Internet, from introducing numerous regulations to encouraging self‐censorship, with some success. This paper will examine state‐coordinated measures to control the use of the Internet, look at how the Internet could be making CCP rule more effective, and consider the validity of the argument that the Internet represents a threat to CCP rule.  相似文献

Indicators explaining gender differences in personality and pain among older cancer patients have not been adequately addressed. This study examined gender differences in cancer-related pain severity, the Five Factor Model of personality, and affect among older cancer patients (86 women, 64 men). No significant differences were found in pain severity between the gender groups. Analyses indicated that women scored significantly higher for the personality trait of neuroticism than men (p < .05). Further analyses showed that different demographic, health, and personality variables predicted pain severity in women and men. Gender was found to be a significant moderator in the association between the personality trait of neuroticism and average pain. These findings suggest that both gender and different personality types may influence reported pain severity. Specifically, the results suggest that how patients experience and report pain severity may be gender-specific, and that it may be inappropriate to assume that women and men experience, report, and manage their pain in similar ways. Future studies focusing on the influence of personality and gender on health outcomes are needed to assist healthcare providers in tailoring treatment, thereby promoting optimal symptom management.  相似文献

Indian snakeroot (Rauvolfia serpentina) is a valuable forest product, root extracts of which are used as an antihypertensive drug. Increasing demand led to overharvesting in the wild. Control of international trade is hampered by the inability to identify root samples to the species level. We therefore evaluated the potential of molecular identification by searching for species‐specific DNA polymorphisms. We found two species‐specific indels in the rps16 intron region for R. serpentina. Our DNA barcoding method was tested for its specificity, reproducibility, sensitivity and stability. We included samples of various tissues and ages, which had been treated differently for preservation. DNA extractions were tested in a range of amplification settings and dilutions. Species‐specific rps16 intron sequences were obtained from 79 herbarium accessions and one confiscated root, encompassing 39 different species. Our results demonstrate that molecular analysis provides new perspectives for forensic identification of Indian snakeroot.  相似文献
