Cost Escalation in Nuclear Power

This report is concerned with the escalation of capital costs of nuclear central station power plants between the early 1960s and the present. The report presents an historical overview of the development of the nuclear power industry and cost escalation in the industry, using existing data on orders and capital costs. New data are presented on regulatory delays in the licensing process, derived from a concurrent study being carried on in the Social Science group at Caltech. The conclusions of the study are that nuclear capital costs have escalated more rapidly than the GNP deflator or the construction industry price index. Prior to 1970, cost increases are related to bottleneck problems in the nuclear construction and supplying industries and the regulatory process; intervenors play only a minor role in cost escalation. After 1970, generic changes introduced into the licensing process by intervenors (including environmental impact reviews, antitrust reviews, more stringent safety standards) dominate the cost escalation picture, with bottlenecks of secondary importance. Recent increases in the time from application for a construction permit to commercial operation are related not only to intervenor actions, but also to suspensions, cancellations or postponements of construction by utilities due to unfavorable demand or financing conditions

Factor Bias and Innovations: A Microeconomic Approach

This paper contains a microeconomic analysis of the influence of change in relative prices on the direction of inventive activity. A control-theory model of a firm which produces final output and also performs research and development is developed. It is assumed that the output of R & D is factor-augmenting technical change. An innovation possibility frontier for the firm is defined and conditions are found under which it is convex. The major theorems relate the change in innovation in response to changing factor prices to the elasticity of substitution in producing final output and to the nature of the production functions for innovation. Two special cases are examined in detail. When current innovation possibilities are appropriately independent of past innovations, the rate of factor augmentation is the same for all factors where relative prices are constant at any level. Comparing time paths with different, constant relative prices gives conditions under which an increase in the price of a factor directs innovation into lines which economize on that factor. A summary of earlier results on similar subjects is included

Synthesis of Cyclic Py-Im Polyamide Libraries

Cyclic Py-Im polyamides containing two GABA turn units exhibit enhanced DNA binding affinity, but extensive studies of their biological properties have been hindered due to synthetic inaccessibility. A facile modular approach toward cyclic polyamides has been developed via microwave-assisted solid-phase synthesis of hairpin amino acid oligomer intermediates followed by macrocyclization. A focused library of cyclic polyamides 1–7 targeted to the androgen response element (ARE) and the estrogen response element (ERE) were synthesized in 12–17% overall yield. The Fmoc protection strategy also allows for selective modifications on the GABA turn units that have been shown to improve cellular uptake properties. The DNA binding affinities of a library of cyclic polyamides were measured by DNA thermal denaturation assays and compared to the corresponding hairpin polyamides. Fluorescein-labeled cyclic polyamides have been synthesized and imaged via confocal microscopy in A549 and T47D cell lines. The IC_50 values of compounds 1–7 and 9–11 were determined, revealing remarkably varying levels of cytotoxicity

Factors Affecting Retention of Undergraduate Students in Fisheries and Wildlife Programs

Undergraduate enrollment in agriculture and natural resources‐related programs has steadily declined for the past decade or more. College administrators and faculty struggle to separate the real causes of this decline from the superficial and often mythical factors. How programs should address this decline is of similar concern. Rather than speculate on why students do not pursue a degree in a natural resources field, specifically fisheries and wildlife (FW), we decided to investigate the question of FW student retention from the perspective of the students themselves. Specifically, we wanted to know: (a) Why do students say they chose to leave the FW program at MSU? (b) Why did students who persisted in program say they chose to stay? and (c) What reasons did transfer students give for choosing FW as a major? We conducted a series of face‐to‐face interviews with these three groups of students, and asked them a series of 10‐14 questions related to their experiences in the Department of Fisheries and Wildlife at Michigan State University in an effort to better understand student reasons for leaving, persisting, and immigrating into the program. Although our project is just beginning, preliminary results offer some interesting insights into the departure puzzle. Specific, but limited, findings from interviewees include: (a) the importance of job prospects and earnings potential, (b) a general reluctance to pursue postgraduate education, (c) a degree of disillusionment at the relative lack of outdoor experiences offered by the program in classroom and extracurricular activities, and (d) a desire for more active participation and field experiences in the undergraduate program. Several students in this study told us that they selected FW out of a desire to spend more time in the field, and were disappointed this was frequently not the case. Some students expressed a general feeling of deception at the realities of the departmental curriculum, although these were poorly defined and may be the product of other issues such as unrealistic program expectations. This ongoing study has the potential to inform natural resource programs on techniques to attract, retain, and educate undergraduate students
