The assumption that males approach dating from a pronounced psychobiological orientation while females approach it from a psychoaffectional orientation was questioned. The sex role adopted by the individual was considered to be as important a variable as biological sex. Male and female subjects from three age groups, 16–17 years, 19–20 years, and 24–25 years, completed questionnaires designed to measure their sex roles and dating orientations. All groups of males were found to approach the dating relationship from both a psychoaffectional and psychobiological orientation, while all groups of females approached it from a psychoaffectional orientation and showed an increase in psychobiological orientation with increasing age and increasing depth of relationship. Significant differences were also found in dating attitudes between male and female subjects adopting different sex roles. It was concluded that neither masculinity and femininity, nor psychobiological and psychoaffectional attitudes to dating, lie on single continua. Masculine and feminine sex roles as independent dimensions influence psychobiological and psychoaffectional orientations to dating which are in themselves independent dimensions and not ends of a single continuum.Received her B.A. (Hons. 1) at Macquarie University and Dip.

In this study we investigated homicides in the two Scandinavian capitals, Copenhagen, Denmark and Oslo, Norway, for the 10-year period from 1985 to 1994. The total number of homicides was 431; 63.8% occurred in Copenhagen and 36.2% in Oslo. The average homicide rate was 1.6/100,000 in Copenhagen and 1.8/100,000 in Oslo. Blunt force, sharp force, and strangulation were the most common methods. Firearms were also used but did not account for >20% in either of the two cities. This is probably due to strict gun laws in both countries. There was no clear difference between the homicide victim populations in the two cities with regard to age, gender, or social and marital status. The proportion of alcoholics and unemployed persons was much higher than in the background population and to a similar extent in both cities, indicating that the homicide victim populations differ from the background populations. The perpetrator knew the victim in the majority of the cases. The most frequent motives or circumstances in both cities were fights, family rows, financial controversies, or jealousy.  相似文献

Restoration projects and archaeologic excavations in two Canadian prisons resulted in the recovery of the skeletons of six felons executed by judicial hanging. Damage inflicted by hanging on various skeletal elements was observed. Among the injuries seen were fractures of the hyoid cornua, styloid processes, occipital bones, and cervical vertebral bodies (C2) and transverse processes (C1, C2, C3, and C5). Despite the general uniformity of the hanging technique, which involved a subaural knot, the trauma to the skeletal elements and the cause of death varied among individuals. Although some of this variation was probably due to minor differences in hanging practices, individual anatomic peculiarities of the victims likely also contributed.  相似文献

Justice 2002, a strategic agenda for the Arizona court system over the next five years, has the goal to build public trust confidence in the Arizona courts. A focus of Justice 2002 is the protection of children, families, and communities. One of the number of projects that have been initiated is the establishment of The Committee to Study Family Issues in the Superior Court (Committee). On October 22, 1997, Chief Justice Thomas A. Zlaket established the Committee and charged the members to: "[E]xamine the manner in which cases involving family issues, including cases involving minor children, presently are processed and determined in the Superior Court,… leading to improvement in the manner in which these cases are resolved in the court system; and report to the Arizona Judicial Council its findings and recommendations…" This article is a summarization of the Final Report presented to the Arizona Judicial Council (AJC) in December, 1998. The reader will find that the report is rather general. The Committee has functioned under the assumption that an implementation committee would be formed to work out the details, should the AJC choose to adopt the recommendation to establish a Family Court in Arizona.  相似文献

A 53-year-old woman who was diagnosed as suffering from depression was found dead in her bed. The autopsy revealed no morphological changes sufficient to explain death. Toxicological analysis was performed and the drugs trimipramine (2.33 mg/l), citalopram (4.81 mg/l) and zolpidem (0.07 mg/l) were identified in the femoral blood. A combined drug intoxication resulting in synergistic effects to cardiovascular disorders was proposed as the cause of death. An acute overdose and suicide was suggested by calculation of the parent drug to main metabolite ratios in femoral blood and liver tissue. The trimipramine to desmethyltrimipramine ratios were calculated to be 2.06 and 3.18, the citalopram to desmethylcitalopram ratios were 1.96 and 2.02.  相似文献
