Previous research has established that perpetrators of homicide-suicide share more characteristics with those who commit suicide than they do with those who commit homicide without suicide. This article examines the characteristics of victims, perpetrators and the circumstances leading to the homicide of a sample of familial homicide-suicides and familial homicides in southwest British Columbia. A familial homicide was defined as one in which the victim and perpetrator were related directly or indirectly through blood or an intimate relationship. Suicide only occurred following the killing of an intimate partner and/or offspring. Consistent with an evolutionary perspective, homicides followed by suicide were most often attributable to male proprietariness (manifested by killing former intimate partners or offspring following an intimate separation) or mental illness. By contrast, none of the murders which occurred as a result of violence by the victim, child abuse, family conflict, or financial/criminal motives was followed by suicide.

65%, increased hydrolysis of the soap gave, as was anticipated, higher saponification values Effect of Exposure of Samples to Air. Although usual precautions had been observed to minimize exposure to the atmosphere during the analysis of the samples reported in Table I, it was believed that the lack of close agreement might have been due to variations in carbon dioxide absorbed.To study this factor, a series of analyses was made in which the opportunity for absorption of carbon dioxide ivas varied.

Educators in all academic disciplines have been encouraged to utilize assessment strategies to evaluate students' critical thinking. The purpose of this study was to assess the viability of the modiied objective structured clinical examination (m-OSCE) to evaluate critical thinking in dental hygiene education. This evaluation utilized a convenience sample of senior dental hygiene students. Students participated in the m-OSCE in which portions of a patient case were revealed at four stations. The exam consisted of multiple-choice questions intended to measure students' ability to utilize critical thinking skills. Additionally, there was one ill-in-the-blank question and a treatment plan that was completed at the ifth station. The results of this study revealed that the m-OSCE did not reliably measure dental hygiene students' critical thinking. Statistical analysis found no satisfactory reliability within the multiple-choice questions and moderately reliable results within the treatment planning portion of the examination. In addition, the item analysis found gaps in students' abilities to transfer clinical evidence/data to basic biomedical knowledge as demonstrated through the multiple-choice questioning results. This outcome warrants further investigation of the utility of the m-OSCE, with a focus on modiications to the evaluation questions, grading rubric, and patient case.
