In this article, the 2008 annual lecture of The Women’s Library, London Metropolitan University, the author reflects on the ninety years since 1918 when certain categories of women over the age of thirty (about 8 million) won the right to the parliamentary vote in Britain. In particular, women’s participation in politics in societies worldwide is discussed. 相似文献

This study utilizes an innovative 3D approach to discover metric variables that obtain the highest classification rates for sex estimation from the cranium. Models were constructed from 222 cranial CT scans of U.S. Whites from the Bass Donated Collection. These models were used to create a statistical bone atlas that captures the primary shape variation in the skull and facilitates rapid computer‐automated analyses. The bone atlas showed that important size‐related sex variables are bizygomatic breadth, maximum cranial length, cranial base length, and mastoid height. Shape‐related variables capture sex differences in the projection of the glabellar region, inclination of the frontal, and cranial base flexion. In addition, vault thickness is highly dimorphic, with females having on average thicker vaults in the frontal region, and males having thicker vaults in the occipital region. Cross‐validated linear discriminant analysis obtained >95% accuracy (97.5% with 11 variables and 95.5% with eight variables). 相似文献

This study examines spheno-occipital synchondrosis fusion in the modern American population and presents age ranges for forensic use. The sample includes 162 modern individuals aged 5-25 years. The basilar synchondrosis was scored as open, closing, or closed via direct inspection of the ectocranial site of the suture. Transition analysis was used to determine the average ages at which an individual transitions from unfused to fusing and from fusing to fused. The maximum likelihood estimates from the transition analysis indicate that females are most likely to transition from open to closing at 11.4 years and males at 16.5 years. Females transition from closing to closed at 13.7 years and males at 17.4 years. The probability distributions associated with these maximum likelihood estimates were used to derive age ranges for age estimation purposes. These results reflect sexual dimorphism in basilar synchondrosis fusion and agree approximately with average age at pubertal onset. 相似文献

Abstract: Clavicles from 1289 individuals from cohorts spanning the 20th century were scored with two scoring systems. Transition analysis and Bayesian statistics were used to obtain robust age ranges that are less sensitive to the effects of age mimicry and developmental outliers than age ranges obtained using a percentile approach. Observer error tests showed that a simple three‐phase scoring system proved the least subjective, while retaining accuracy levels. Additionally, significant sexual dimorphism was detected in the onset of fusion, with women commencing fusion at least a year earlier than men (women transition to fusion at approximately 15 years of age and men at 16 years). Significant secular trends were apparent in the onset of skeletal maturation, with modern Americans transitioning to fusion approximately 4 years earlier than early 20th century Americans and 3.5 years earlier than Korean War era Americans. These results underscore the importance of using modern standards to estimate age in modern individuals. 相似文献

Because loyalty and trust are viewed as key requirements for relationships with friends as well as with romantic partners, acts of betrayal, which violate the trust on which these relationships are based, are viewed as serious transgressions. This study focused on 2 commonly occurring kinds of betrayal—betrayal of a friend's confidence despite a promise not to do so and sexual betrayal by a romantic partner despite an agreement to be monogamous. Approximately 261 college students, aged 18 to 23, answered questions concerning the acceptability of betrayal under a variety of different conditions and described their self-restraint, tolerance of deviation, and betrayal behavior. Despite pervasive disapproval of betrayal, the extent of disapproval was a function of the type of betrayal (whether of a romantic partner or a same-sex friend), the justification for the betrayal, the sex of the transgressor, and the characteristics of the respondent. There was greater acceptance of sexual betrayal than betrayal of a friend's confidence, of male than female transgression, and by male than female respondents. These results are largely accounted for by the finding that male respondents gave high ratings of acceptance of sexual betrayal by male transgressors. Acceptance of both forms of betrayal was correlated with lack of self-restraint, tolerance of deviation, and behavioral betrayal. 相似文献
