For more than ninety years, between 1921 and 2012, our knowledge of the Broken Hill Man phase of human evolution has been provided by scholars who have been able to access the skull in England, where it was taken in 1921. This paper presents findings of the circumstances under which the skull was discovered in Northern Rhodesia and taken to England, its significance to science, and issues relating to its return to Zambia. The study grew out of the disillusionment of Zambians due to the reluctance of the Natural History Museum in London to repatriate the skull to its country of origin. The study has established that despite the existence of a legal framework in Northern Rhodesia to regulate the removal of relics from the territory, which was then under the administration of the British South Africa Company, the Rhodesia Broken Hill Mine Company donated the skull to the British Museum (Natural History) without obtaining an export permit. It is within the context of the findings and arguments advanced by the parties involved in the claim of ownership that this paper advocates for the return of the skull to Zambia.  相似文献

We examine how the congressional coalition in favor of a law affects the probability of the president appending a positive or negative signing statement to it. Our results show that coalitions matter—presidents consider the power and status of a law's sponsor and the composition of its cosponsorship coalition when deciding whether to offer praise or raise concerns. Moreover, the factors driving praise and criticism differ from one another in important ways. These analyses demonstrate the value of assessing the valence of a signing statement rather than just its presence, and of extending the focus of research on signing statements beyond aggregate factors to investigate how the context surrounding a particular law shapes the president's reaction to it.  相似文献

In the history of neurology, Achille Louis Foville (1799-1879) is a name deserving to be remembered. In the course of time, his circonvolution d'enceinte of 1844 (surrounding the Sylvian fissure) became the ‘convolution encompassing’ every aspect of aphasiology, including amusia, i.e., the localization in a coherent semicircle of cerebral cortex serving the production and perception of language, song and instrumental music in health and disease.  相似文献
