Griliches (1958) [Journal of Political Economy,66: 419--431] and Mansfield et al. (1977) [Quarterly Journal of Economics 91: 221--240] pioneered the application of fundamental economic insight to the development of measurements of private and social rates of return to innovative investments. This paper illustrates field-based methods for measuring the social rates of return to innovative investments by the public sector. The case study described herein relates to the development of an improved standard reference material for the measurement of the wavelength of light in an optical fiber network. 相似文献

This article will focus on the evolution of the collaborative work of the Louisiana Rural Trauma Services Center (LRTSC), a Center within the National Child Traumatic Stress Network, and the 23rd Judicial District, a jurisdiction in south Louisiana serving three rural parishes. We will describe how the collaboration and joint efforts, and the changes that have been made in terms of availability of evaluation and treatment resources, seem to be influencing both the educational and judicial systems in St. James Parish and potential sustainability of some of the identified resources. The article will examine how the court and the LRTSC work together with emphasis on the evaluation, reporting and recommendation processes, outcomes and benefits to date, and challenges for the future. 相似文献
