This study shows the spatial juxtaposition and separation of topics regarding law in Thomas Aquinas’ Summa theologiae. These topics are his treatise on legal structures among morals in its part I-II, and his treatise on legal justice among virtues in its part II-II. This difference in the topics’ placements requires mediation by the virtuality of law, in order to grasp the distances and bridges between the two treatments of law.  相似文献

Due to an awareness of the frequency of child abuse and lack of a single instrument to assess the extent of exposure to both the abusive and supportive environments provided by parents, a 70 item inventory (the EASE-PI) was developed that is a self-report on how both mother and father treated the respondent. A factor analysis, which was subsequently replicated, revealed three abusive factors (representing emotional, physical, and sexual abusiveness) and three supportive factors (love/support, promotion of independence, and positive modeling/fairness). The same factors emerged regardless of gender of respondent and gender of parent. The inventory provides a means to investigate the differential and interactive effects of exposure to emotional, physical, and sexual abusiveness and the possible mitigating effects of different types of supportive behaviors by each parent.  相似文献

In only nine of approximately 600 cases of child molestation in New Hampshire and Vermont was the perpetrator found to be a woman. Case histories and some testing data show a history of sexual assault as a child, frequent offense in the company of a dominant male partner, and a major disinhibition as a result of severe character disorder or limited intelligence. These factors not only interfered with maternal bonding and nurturing behavior but also contributed to suspension of judgment about the appropriateness of sexual contact with children.  相似文献

Untreated traumatic rupture of the aorta generally results in sudden death. A case with 14 years' survival after an unrecognized traumatic rupture of the aorta is presented. Chronic traumatic aneurysm of the aorta should be kept in mind in a patient who develops sudden symptoms of arteriosclerotic heart disease months to years after a relevant thoracic trauma.  相似文献

This paper reports the case of a 22-year-old white male who was found dead in a storage room as a result of a fatal ingestion of cyclopropane. Cyclopropane is a sweet-smelling, irritating gas. Autopsy findings revealed congestion and hemorrhagic edema of the lungs, congestion of the trachea, and early autolysis. Cyclopropane was determined by headspace gas chromatography and mass spectrometry. To our knowledge, this is the first reported fatality involving cyclopropane.  相似文献
