This exploratory study examined the relationship patterns of child abusers in treatment by comparing interactions involving the therapist with those involving a parent. Twenty participants were included in the study. The participants' relationship patterns were assessed using the core conflictual relationship theme (CCRT) method. Core schemas were found in interactions involving the therapist and a parent. The two CCRTs found in interactions with parents were often motivated by a desire for closeness or intimacy, to which the parent reacted with rejection or domination. The participants then felt disappointed, depressed, and unreceptive. In relationship episodes involving the therapist, a similar desire for closeness was answered with help and cooperation from the therapist, hence leading the participants to feel self-controlled and self-confident. Furthermore, the therapist's criticism and opposition was often experienced as an indication of care and acceptance. 相似文献

In a simulated products liability trial, we tested the effects of bifurcating decisions regarding compensatory and punitive damage awards. Fifty-nine groups of 5-7 jurors heard evidence in a unitary or bifurcated format, deliberated about the case to a unanimous decision, and awarded damages. Trial bifurcation decreased variability in compensatory damage awards across juries hearing the same case, and also decreased the tendency for juries to award extremely high compensatory damages. In addition, deliberation led to lower compensatory awards in the low injury severity condition and higher awards in the high injury severity condition. Jurors reported that they were using evidence more appropriately when the decisions were bifurcated. Implications of evidence bifurcation in civil trials are discussed. 相似文献

In forensic autopsies, one of the most important and common signs of violence to the neck is hemorrhages of the soft tissues. The Institute of Forensic Medicine in Bern evaluates the usefulness of postmortem multislice computed tomography (MSCT) and magnetic resonance imaging (MRI) of forensic cases prior to autopsy. The aim of this study was to prove the sensitivity of postmortem MSCT and MRI in the detection of hemorrhages of the neck muscles. A full body scan prior to and a detailed scan of the explanted larynx after autopsy were performed. MSCT detected multiple fractures of the larynx. Detailed MRI was able to demonstrate the hemorrhage of the left posterior cricoarytenoid muscle. The minor hemorrhage of the right posterior cricoarytenoid muscle could not be detected with certainty. Although more experience is required, we conclude that combined MRI and MSCT examination is a useful tool for documentation and examination of neck muscle hemorrhages in forensic cases. 相似文献

This report highlights the importance of undertaking immunohistochemical staining of the brains of infants who die unexpectedly, as it may not only assist with the evaluation of the cause of death in an individual infant but may also help with the clinical management of subsequent siblings. A 5-month-old male infant who died suddenly was found to have diffuse beta-amyloid precursor protein (beta-APP) staining in the brain, with no unusual features in his history, death scene examination, routine autopsy dissection, and ancillary tests to suggest any definite cause of death. Due to the beta-APP staining, the possibility of previous episodes of occult trauma, apparent life threatening events (ALTEs), and accidental or inflicted suffocation was raised in the autopsy report. As detailed analyses and investigations provided no supportive evidence for trauma or inflicted injury, hypoxia was clinically considered the most likely cause. Because of these concerns, sleeping oxygen saturation levels were monitored following the birth of a subsequent sibling who had normal APGAR scores and no evidence of any health problems. Oxygen desaturation to 70% occurred in association with a color change while on the postnatal ward, and a subsequent polysomnogram showed multiple episodic significant desaturations to around 80% in association with central apnea. Other testing was unremarkable. These cases demonstrate that beta-APP staining of the brain may not only provide clues as to possible mechanisms of death in pediatric forensic cases but may indicate a need for careful clinical evaluation of subsequent siblings for possible central apnea requiring oxygen therapy. 相似文献
