Abstract This study examines changes in legislative support for the governor's legislative agenda in Georgia during the governor's first term in office (1991–94). I analyze the factors that led legislators to support the governor's agenda, as well as how the level of support changed between election years and off‐years. I use multivariate OLS models of gubernatorial support to determine how support varied (1) between the parties, (2) between factions within parties, and (3) over time. I find that there was wide variation in support among factions in the majority party and that support varied widely between election years and off‐years.  相似文献

Unwanted sexual attention (UWSA) encompasses unsolicited verbal comments, gestures, stares, and other noncontact behaviors made regarding one's sexuality and physical appearance. The present study examined the correlates and impact of such UWSA perpetrated toward girls by family members. The first objective of the study was to explore whether family climate is associated with intrafamilial UWSA. This included looking at three types of dysfunctional parenting styles (unaffectionate, unavailable, and patriarchal) as well as exploring the co-occurrence of UWSA by adult and child relatives. The second objective was to then measure the impact of such intrafamilial UWSA on childhood emotional health, after controlling for parenting style and the experience of more traditional forms of child sexual abuse (CSA). Of the 296 university women (mean age = 19) who participated in the study, 70% (N = 206) reported UWSA from a family member prior to age 18. Whereas each dysfunctional parenting style was related to presence of UWSA, a simultaneous multiple regression analysis indicated that two of the parenting styles, patriarchal and parental unavailability, also predicted frequency of nonphysical UWSA within the family. Presence of UWSA from a child relative was significantly correlated with presence of UWSA from an adult relative. Additionally, a hierarchical multiple regression, entering the three parenting styles simultaneously in the first step, childhood sexual abuse in the second step, and familial UWSA in the last step, indicated that the frequency of UWSA by family members significantly predicted poorer childhood mental health when controlling for the other variables. Overall, results indicate that while the specific parenting styles which co-occur with UWSA may be detrimental in their own right, the impact of UWSA on girls appears to be above and beyond that of either parenting styles or CSA. Clinical implications are discussed.  相似文献

人离体肝组织胺类产生与死亡时间和环境温度的关系   总被引:3,自引:1,他引:2  
目的探讨在不同环境温度下,人离体肝组织中有机胺类产生量随死亡时间变化的规律,为某些碎尸案的死亡时间推断提供参考资料。方法应用高效液相色谱仪外标法,动态检测人离体肝组织中组胺、腐胺、尸胺和未腐败氨基酸含量。结果在8℃、15℃、23℃和32℃环境下,有机胺类产生量分别于人死后肝脏即刻离体69h、54h、40h和33h趋于最大值,并且在到达峰值之前,各温度组离体肝组织中有机胺类生成量均与死亡时间成正比关系。结论人离体肝组织中有机胺类产生量与死亡时间和环境温度在一定范围内均呈正相关。  相似文献
