This article reports on a study of technological innovations in state and local government agencies. The study was based on an aggregate analysis of 140 previously published and unpublished case studies, in which a closed-ended questionnaire was used to extract information from the case studies. The main hypotheses and findings of the study concern the possible existence of two innovative processes, one that emphasizes service improvements but that does not necessarily lead to enduring incorporation of the innovation (production efficiency), and the other that emphasizes incorporation even where the innovation may not have produced a demonstrable service improvement (bureaucratic self-interest).This study was supported in part by a grant from the Office of R&D Assessment, National Science Foundation, though the author alone is responsible for the views expressed here.  相似文献

On 21 February 1890, two woodsmen working in densely wooded Blenheim Swamp in southern Ontario, Canada, stumbled upon the dead body of a young Englishman who had been killed by two gunshot wounds to the head. He was identified as Frederick Benwell by a married couple, the Birchalls, who had traveled with him and another man, Pelly, from England to New York City by ship about 1 week before. The Birchalls lied regarding Benwell's subsequent movements. Questioning Pelly revealed to Detective John Murray that both Pelly and Benwell had replied separately to Birchall's advertisement for young men of means to become partners with him in a large Canadian farm, a deposit first being required. Birchall had been observed taking Benwell from Buffalo, New York, to Blenheim Swamp, for in reality there was no farm. There he had shot Benwell, leaving the body partially exposed. He then tried unsuccessfully to lure Pelly to his death in Niagara Falls. The Birchalls were arrested. Reginald Birchall was tried, convicted, and hanged. His attempt, including murder, to turn the so-called farm pupil colonization scheme to his own benefit had been frustrated by the dogged work of the master Canadian detective Murray.  相似文献

For almost forty years, legislators have advocated comprehensive measures designed to assure Americans quality health care. Instead of implementing an integrated health care plan, Congress has intermittently enacted statutes which address specific health care delivery problems. At times the judiciary has stretched the ambit of existing health legislation in response to particular plaintiffs' urgent claims. This Case Comment examines the dilemma of piecemeal legislation and judicial policymaking as exemplified by Presbyterian Hospital of Dallas v. Harris, a Fifth Circuit Court of Appeals health care financing decision whose outcome Congress has flatly rejected.  相似文献
