Tooth mineralization standards for blacks and whites from the middle southern United States 总被引:1,自引:0,他引:1
Normative standards are provided for permanent tooth mineralization stages for blacks and whites of the middle southern United States. The data cover tooth development from 3.5 to 13 years of age. Females develop more rapidly than males, and blacks are nearly twice as sexually dimorphic (7.2%) as whites (3.7%). Within each sex, blacks achieve mineralization stages significantly earlier, by about 5%, than whites. This complements earlier findings that teeth erupt at appreciably earlier mean ages in blacks. 相似文献

Current studies of courtroom decisionmaking emphasize contextual variation and the interaction of large numbers of variables In explaining decision outcomes. However, theory suggests that courtroom decisions may be dominated by simple "rules of thumb" that allow decisionmakers to cope with scarcity of time and resources. Following this approach, a parslmonious model of plea bargaining as a two-person game is developed and hypotheses are derived. Data on negotiated sentences for burglary and robbery in three California counties serve to test the hypotheses. The findings confirm that prior criminal history is the dominant factor in determining the severity of negotiated sentences and that defendents with more extensive prior records have less incentive to plea bargalh. Identlfication of this decision rule for negotiated sentences contradlcts arguments for limiting plea bargaining that assume negotiations result in sentencing leniency across the board. 相似文献

ABSTRACTRather than studying young men's career- and/or economic-based aspirations, this article explores the obstacles that hinder youths of both sexes in gerontocratic southern Tajikistan and North India from developing the capacity to make their own life choices. Focusing mainly on the selection of marital partner and largely on women, I explore the narratives of those who have never even dreamed of a good life, of others who have dreamed but been unable to actualize their dreams, of a few who have started to plan the way forward, and of a tiny number who actually managed to achieve their aspirations, teasing out the influences that facilitate this. I suggest that even educated youths with some control over their public lives are constricted by their family relations and that it requires quite specific support to defy one’s family, which can create significant vulnerabilities in settings with no other safety net. 相似文献
