Until the latter part of the 20th century, legal doctrines made it almost impossible to successfully prosecute in criminal court a case involving child sexual abuse (CSA), whether the complaint was timely or delayed. Many English-speaking countries have abrogated most formal legal barriers to prosecuting CSA cases, and courts are faced with the singular challenge of adjudicating sexual offenses against children that are reported to have happened years or decades earlier. We conducted analyses of 4,237 criminal complaints of CSA heard in Canadian criminal courts. There were several differences between timely and delayed prosecutions that led us to conclude that delayed prosecutions of CSA are common and due, in part, to the nature of the offense. Offense duration was associated with longer delays to prosecution. When the accused had access to the child through his position in the community, length of delay to prosecution was very long, particularly for male complainants. More research is needed on delayed CSA prosecutions, particularly given an apparent trend for jurisdictions to abolish barriers to criminal prosecutions of CSA that occurred years or decades earlier.

Compared ambulatory blood pressure (BP) and heart rate (HR) in 30 paramedics during a 24-hr workday and a 24-hr nonworkday. During the 24-hr period as a whole, there were no BP differences between the workday and the nonworkday, but HR was higher during the nonworkday than during the workday. Systolic BP (SBP) recorded in the ambulance on the workday was elevated 9.8 mm Hg, compared to SBP recorded in a car on the nonworkday; it was also 7.2 mm Hg higher at the scene of an accident and at the hospital than during nonworkday activities. Ratings of moods in diaries indicated that paramedics felt more unhappiness, stress, and sadness and less feelings of pleasantness at work than at home. Rather than being elevated for the entire 24-hr period, work BP seemed to reflect the relatively high stress associated with specific situations in the work of a paramedic. 相似文献
