Stephen J. Wayne 《Congress & the Presidency》2013,40(2):199-209
Eisenhower's contributions to the modern presidency are primarily institutional and to some extent, stylistic: his reliance on the professionalism of civil servants in the Bureau of the Budget, his continuation of the annual programming process as well as the procedures for coordinating the executive branch's legislative role, his creation of a White House office to represent him on Capitol Hill, and his respect for Congress as a legislative body. What Eisenhower did not do is equally significant: he did not reject the model of an activist presidency, reverse the New and Fair Deal policies of his Democratic predecessors, or pursue his centrist agenda in a blatantly partisan manner. The Eisenhower experience demonstrates that incivility, inhumanity, and inanity are not inevitable consequences of divided government. 相似文献

This paper explores the implications of an early criticism of the stimulation studies of Fritsch and Hitzig and Ferrier for localized brain functions. Fritsch and Hitzig and Ferrier concluded that motor centers reside in the cortices of the hemispheres. Their studies were replicated, but their conclusions were not generally accepted initially. The most salient, laboratory-based criticism was that the electrical current used for stimulation diffused well beyond the cortex making their conclusion of cerebral motor centers unacceptable. The diffusion argument was essentially a French suggestion. Ferrier's and American research and interpretations provided data and arguments against it. 相似文献

Three American neurologists (C. K. Mills, C. L. Dana, and M. A. Starr) explored the anatomical limits of the motor and tactile systems in the brain from 1884 to 1895. Their papers and critiques of one another show contemporary knowledge, limits of their thinking, and difficulties deciding between alternatives. The issue for them was whether there were separate sensory and motor regions or whether there was a combined sensory-motor region. They based their localization arguments on clinical and laboratory findings and on the conclusions of H. Munk and D. Ferrier. There is a discussion about why differences were unresolved. 相似文献

The author considers three methods of counting maternal deaths, and hence of calculating maternal mortality levels, in the nineteenth century. The first method counts maternal deaths classified in contemporary statistical publications. The second method examines nineteenth-century death registers for records of maternal deaths. The third method identifies maternal deaths through family reconstitution. The author finds that each method, in isolation, leads to underestimating maternal mortality levels because maternal deaths were often misregistered or misclassified under nonmaternal causes and were often not associated with live, registered births, as required for family reconstitution. 相似文献

In November 2008, human skeletal remains were discovered during construction works undertaken by Carlop Properties in the Chloorkop industrial area, Kempton Park, Gauteng. The Forensic Anthropology Unit of the University of Pretoria, Forensic Anthropology Research Centre (FARC) was notified, and rescue excavations of both the exposed and the undisturbed remains were undertaken. The skeletonised remains of at least 18 individuals were recovered and sent to the Department of Anatomy at the University of Pretoria for standard anthropological analysis. The identity and the time period of these human remains are unknown, and during social consultation, no relatives could be identified. Excavations revealed a formal burial pattern, which suggests a formal cemetery, probably associated with a historic institution. All individuals were buried in wooden coffins in an extended, supine position. The remains consist of both adult and juvenile remains. Some of the remains were found in a commingled state because of disturbance caused by construction work. The minimum number of individuals was determined by the visual pair matching of skeletal elements on the basis of similarities observed in bone morphology, age and sex, trauma and pathology and taphonomic alterations. Bioarchaeological techniques were used, and the following results were obtained. Of the 18 individuals, at least 15 were identified to be males, one possibly female and two juveniles. At least five of the adult male individuals presented with cut marks associated with standard autopsy procedures. No reference to the individuals' identity or to the context of the cemetery within the historical span of the Chloorkop area has been located. However, the burial pattern observed, as well as the demographic profile and pathology observed on the skeletal remains, suggests that these individuals could be linked to the Klipfontein Organic Products Factory (ca 1941s–1970s), which employed many migrant labourers, most to whom lived in compounds on the factory premises.
