Evaluating Public Sector R&D Programs: The Advanced Technology Program's Investment in Wavelength References for Optical Fiber Communications

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.

'A Single Truth': Mill on Harm, Paternalism and Good Samaritanism

On Liberty provides the classic defence of what has come to be known as Mill's harm principle and yet that principle is commonly believed to be at odds with Mill's equally famous discussions of paternalism and good samaritanism. Moreover, the alleged inconsistencies are often said to expose the inadequacies not only of Mill's anti-paternalism and good samaritanism but his harm principle as well. This paper offers a re-interpretation of these three aspects of On Liberty . It attempts to show both the unity of Mill's thought and how the contemporary relevance of his ideas has been misunderstood.     

Trauma Interventions and Systems Change in Rural Areas: The Role of the Juvenile Court Judge in Collaboration with Mental Health Professionals

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.
