Women have made great strides in the past 100 years. As the iconic cigarette commercial told us almost 50 years ago, “You've come a long way, baby!” Yet women are still underrepresented in the highest leadership ranks, including state and federal office. Before being asked to “lean in” or share valuable insights, a small group of very capable women were leaders long before those two words were seen in the same sentence. One such remarkable woman, Helen Holt, was a “servant‐leader” throughout her illustrious and inspiring career as a member of West Virginia's House of Delegates, then as secretary of state (1957–58), and later as a presidential appointee charged with developing the nation's nursing home system. Holt's work in state and federal government, her appointment by seven U.S. presidents to develop and implement the national nursing home program that is still in use today, and her leadership in civic and nonprofit organizations have made her an inspiration to countless women and men. 相似文献

The recurrent crises emanating from North Korea, and the response to them, is testing US‐China relations and drawing the new boundaries of power in East Asia. The head of the US Joint Chiefs of Staff and the former South Korean national security advisor address this development. 相似文献

In this article, we will compare ethical issues raised by first and second generation biometrics. First generation biometrics use characteristics readily visible to the naked eye to ensure that the person identified is the person he claims to be, whereas second generation biometrics focus on behavioral patterns with the aim of predicting suspicious behavior or hostile intentions. While the collection of biometric features for identification is visible to the person involved, capturing biometric features from a distance may go unnoticed. Our study of a range of U.S. and European projects of second generation biometrics, particularly of Future Attribute Screening Technology and Automatic Detection of Abnormal Behaviour and Threats in crowded Spaces, shows that if data subjects are not aware of the processing of their data, and if behavioral patterns are interpreted without any knowledge of the subject's will and motives, there are risks of discrimination and stigmatization. Thus, second generation biometrics raise some new ethical concerns besides issues of integrity, privacy, and data protection and further underscore the importance of the principle of informed consent in order to maintain public trust. 相似文献

The life‐course approach to criminal career research has devoted a good deal of attention to the generality or specialization of offending behavior. Typically, extant research demonstrates versatility on the part of offenders, yet such findings could be attributable, at least in part, to time and measurement aggregation bias. This work uses a temporally disaggregated and individualized measure of diversity in offending to determine whether the previous findings of generality hold up to shifts in methodology. Using data from a sample of serious felons, results indicated that the magnitude of specialization is greater than in prior studies. Regression results indicated that certain demographic and local life‐circumstance variables are related to the extent of diversity. Theoretical and methodological implications are identified and discussed. 相似文献
