Based on Satow's own account of the conference in his diaries, this article examines the role played by Sir Ernest Satow as the second plenipotentiary on the British delegation at the Second Hague Peace Conference in 1907. His previous experience at the post-Boxer conference at Peking in 1900-1901 stood Satow in good stead during the preparations for the conference as well as once the actual negotiations commenced. His main contribution to the proceedings at The Hague, however, was the preparatory work for the London Naval Conference of 1909. Satow's stance towards the negotiations of 1907 marks him out as a predecessor of twentieth-century internationalists.  相似文献

In this study, we examined the role of dispositional optimism in mediating distress among students who experienced traumatic events, including child physical abuse, emotional abuse, and sexual abuse. Participants included 199 undergraduate and graduate students (aged 18–63 years) from a private university in Oregon. In this study, dispositional optimism partially mediated distress among individuals who had experienced child physical abuse and child emotional abuse; participants with higher levels of optimism had lower levels of distress. In addition, dispositional optimism fully mediated distress among individuals who had experienced traumatic events such as rape, assault, and fire; participants with higher levels of optimism had lower levels of distress. Contrary to prediction, the experience of child sexual abuse was not associated with distress. Clinical implications of these results are addressed.  相似文献

We consider two important notes on optimal law enforcement with corruption. First, we analyze the role of asymmetric information on the emergence of collusion between criminals and enforcers. Second, our paper proposes that the optimal criminal sanction for the underlying offense is not necessarily maximal. We achieve this result by coupling the criminal sanction for the underlying offense with a criminal sanction for corruption, both imposed on offenders. A higher criminal sanction for the underlying offense implies that the government must spend more resources to detect and punish corruption (since the likelihood of collusion increases). Thus, the government could reduce this sanction, save on detection, and increase the criminal sanction for corruption (in order to offset the negative effect on deterrence). We are grateful to Mitch Polinsky and two anonymous referees for helpful suggestions. The usual disclaimers apply.  相似文献

This study examines whether or not using a person as a standard/comparison improves the ability of a child witness to provide more accurate detail about a previously observed person. Study participants included 135 children who observed a male stranger and were then later asked to describe and answer various questions about that person using a third-person standard/comparison. Despite the fact that one-half of participants were exposed to a standard/comparison, neither participants’ gender or exposure to the standard/comparison improved recollection outcomes. However, the gender of the standard/comparisons - especially where female - did have a significant effect on the recall ability of male participants.  相似文献
