Data examined in this study are from the 1976 Mexican Fertility Survey. The authors review previous findings and compare information from this survey with data from the 1969 PECFAL Survey. They then examine the types of consensual union and factors such as women's age, educational status, occupation, premarital fertility, and rural or urban residence. The focus of the study is on the extent to which consensual unions eventually become legal marriages. The authors also investigate the increasing probability of termination of marriage through divorce or separation, especially in urban areas.  相似文献

Much attention has been given of late to the erosion of the "employment-at-will" doctrine. Exceptions to this doctrine began to emerge when courts held that at-will employees could sue if their termination violated public policy. The at-will doctrine was further eroded by court rulings that a contract requiring good cause in order to terminate could be inferred from employee handbooks, company personnel policies, and circumstances of employment. As the initial flood of wrongful termination lawsuits now reaches the appellate level, some guidance on the standards employers must observe can be drawn from court decisions. The authors examine these decisions as well as the legislative reform being proposed in response to them.  相似文献

The intent of this paper is to present some psychological threads which appear to be operative for the perpetrator of bite marks. In the catalogue of multiple motivations, there appears to be a current theme of power, control, potency, and the attempt to have a psychological symbolization of the perpetrator's omniscient capacity for absorbing life essences. In an examination of these highly complex needs, the modern perpetrator appears to act out consistently with cultural biases coupled with immediate psychological needs which have pressed for expression. Due to a pattern of psychologically expressed ritualism, the perpetrator will often inadvertently leave important psychological clues at the crime scene. The attack style, mode of death, characteristics of the victim, etc.--these components reveal the information on the type of psychological needs that the perpetrator is trying to satisfy. In the cases of bite marks associated with violent crime, it becomes crucial to an "investigator" what type of personality characteristics are welded together to form this kind of need complex. After reviewing cases reported in the literature and after conducting psychological interviews with perpetrators, three major groups of perpetrators seem to be apparent. The first group is motivated out of an anger track, the second group is motivated out of sadistic biting, and the third is out of the more traditional "cannibal complex" motif.  相似文献
