By 1996, all states had established a program focusing on the development of technology and technology-based economic development. As more agencies move to performance-based management, state S&T programs are increasingly under pressure to report outcome and output data for their programmatic activities. This paper presents findings on the extent and use of performance measurement and evaluation efforts in state science and technology programs. The 1995–96 study was based on a series of eight case studies and a mail survey of science and technology-based programs in all fifty states. The findings show that three groups of measures emerged as most important to state science and technology programs: employment-related data, leveraged or matching fund data, and anecdotal evidence. State programs are especially pressured to report short-term outcomes, yet show economic benefits. Many state program managers find value in performance data—the reseacch shows that the primary reason that many states assess their performance is the value of performance information as a management tool. Any opinions, findings, conclusions, or recommendations here are those of the authors and do not represent the views of the National Science Foundation. This research was supported under NSF Grant No. SBR-9422433 from the Program of Research on Science and Technology and through the second author's NSF Independent Research Plan. The research benefited greatly from the contributions of two tireless research assistants, Arlene Allen and Michael Turton.  相似文献

Kansas is known for its fierce whether, including tornados in the spring and fall and blizzards in the winter. A recent series of tornados cut a path of destruction a mile wide for greater than 40 miles (64 km), killed 20 people, and caused several hundred casualities on the evening of April 26, 1991, in Tornado Alley, which runs from the northern border of Oklahoma through southern Kansas past Wichita toward Emporium, Kansas. The wind velocity was greater than 200 mph. Twenty people were killed, 17 of these in Andover, Kansas, a small town east of Wichita. Injuries caused by the tornados and the excellent emergency response and care provided by medical, law-enforcement, and volunteer personnel in the wake of the storms are described here.  相似文献

This paper takes issue with a central theme in the literature on corruption that a centralized bureaucratic structure necessarily promotes corruption. It argues that the growth of corruption after 1976 was not so much the result of a centralized bureaucratic structure as that of the changing organizational ethics in the schools. In an examination of the schools since 1949, it shows that their structures have not changed radically. But by separating the organizational ethics into their real and ideal dimensions, it demonstrates that despite the continuity in the official goals and codes of ethics, the ‘real’ or fundamental organizational ethic have changed, and new standards of behavior have prompted members to break organizational rules in the more or less decentralized organizational structures.  相似文献
